Here’s the question:

I enjoy reading and listening to your perspective on Prostate cancer. You mention High grade or Low grade types of cancer. I presume this pertains to the Gleason score? Or are there other factors involved?

 

Here’s the answer:

Assuming the cancer is no where else and is confined to the prostate as best as can be determined (Negative bone scan and neg CT scan) then the most important factor to consider in the prognosis of a patient with prostate cancer is the Gleason’s score.

My dear buddy Jo An Baldwin Peters made a comment on one of the posts yesterday and mentioned that her husband needed a MRI. They live in Canada and she related that the MRI had been scheduled some time in 2013. She mentioned, “Wait until the U.S. gets health care.”

I mention this to say that it is difficult to get a PSA approved in the U.K. because of the criteria that must be met by the family M.D. to justify the test. Keith Cass makes this point on his website www.theredsock.co.uk

So enter a healthy asymptomatic male in his early 40’s to my office last week who because his father had prostate cancer, his family doctor ordered a PSA. He is in turn sent to me and has a normal rectal exam. We elect to do the prostate biopsy and it shows 5 of 12 cores positive for Gleason’s 7 prostate cancer.

Is there anyone in the audience who would argue that he should not have had a PSA drawn? Or that the above scenario will have no impact on his longevity had it not been discovered? Or that, “Well yes it found something this time or this patient, but you can’t do that on everybody. It would be too expensive to test so many people only to find this guy every so often. (You know that is the argument.) Wonder what this particular patient would say to that argument? What do you want for your father, husband or brother.

What say you?

Screening for Prostate Cancer: A Review of the Evidence for the U.S. Preventive Services Task Force.

Chou R, Croswell JM, et al: Ann Intern Med; 2011;155 (December 6): 762-771

Objective: To review the results of recent PSA studies and to summarize this evidence.

Design/Methods: A systematic review (SR) and meta-analysis (MA) of the data were performed for randomized, controlled trials (RCTs) and cohort studies looking at PSA screening and treatments for prostate cancer (PC). The study focused on 4 questions: does PSA screening decrease mortality, what are the harms of screening, what are the benefits of treating early or screened PC, and what are the harms of early treatment?

Results: Conflicting results on PC mortality were seen from 3 specific RCTs, 2 showing benefit and 1 no benefit. Serious infection or urinary retention from biopsy occurred in 1 in 200 men. A 6% absolute survival benefit from radical prostatectomy (RP) versus watchful waiting (WW) was reported from a high-quality RCT, and cohort studies reported consistent benefit to RP and radiation therapy (RT) over WW. Harms from these treatments were erectile dysfunction (ED) in 1 of 3 men after RP, in 1 of 7 men after RT, and incontinence in 1 of 5 men after RP.

Conclusions: Current population-based PSA screening detects more early prostate cancer but results in a small, if any, increase in survival. There are measurable risks of biopsy and significant harms of early treatment.

Reviewer’s Comments: The U.S. Preventive Services Task Force PSA recommendations have sparked a controversy over PSA testing that has forced many stakeholders, including physicians, patients, and ultimately policy makers, to form an opinion on the future of men’s health care. This review presents a well-developed summary of current evidence on PSA screening and standard treatments for PC. What is not immediately clear is how this synthesis should lead to a recommendation against all future PSA screening, as advocated by the task force. Arguments against the task force’s extreme position abound. Final decisions regarding mortality from screening tests should not be made based on early reporting, yet the RCTs included here are only at 9 to 10 year follow-up for a disease with up to a 25-year progression. It may also be inappropriate to combine the data from these trials, as they are extremely heterogeneous in the screened and “unscreened” populations. The number needed to treat cited (48) for survival is likely too high. Estimates from the European Randomized Study of Screening for Prostate Cancer are 12 to 20, and the U.S. Prostate, Lung, Colorectal, and Ovarian subgroup analysis suggests 5. Finally, even without an overall survival benefit, many would argue that the reduction in metastatic and local disease morbidity has provided a significant benefit to the way men currently experience prostate cancer. We should certainly accept the current limitations of PSA, as laid out extremely well by the task force. However, rather than abandon it, we should pursue improvements in its current application.(Reviewer–Steven E. Canfield, MD).

my hypocrisy will go only so far...toomstone... i recognize hypocrisy so easily....in others... jm

The picture above is from knots in a pine board in our river cabin. It looks just like our dog..Chloe.

If you are going to recommend to patients to really consider making a decision about whether they should even have a PSA done because of being diagnosed of a cancer that may not need to be treated (we don’t know which ones) or because there may be devastating side effects to the treatment (impotence and incontinence), should you do that for all cancers? What about colon, lung, thyroid, breast, brain, pancreas etc?

So you pick on prostate cancer because more men die with it than of it? Fair enough.

Which ones die of it instead of it as opposed to with it? What test or study will tell you that before you actually do the biopsy to determine if there is cancer, what is the volume and the Gleason’s score? You don’t know that do you? So you are doing this “informed decision because the “majority” of men die with it instead of it, but not all.

Booyahhhh. Got ya!

Abstract and Introduction

Abstract

The objective was to determine the extent of informed decision making for prostate cancer screening in a defined population. A state-wide population based survey of men aged 50 and above (Behavioral Risk Factor Surveillance System, 2004, Washington state) and a simple random sample of primary care physicians, were conducted in the same geographic area. We examined prostate cancer screening rates among the men (defined as either PSA or digital rectal examination within the past year) and prostate cancer screening practices among the physicians. Screening rates were 56% at ages 50–64, 68% at ages 65–79 and 64% among men age 80 and older. Adjusted analyses indicated that age, income, marital status, possessing health insurance and a personal health care provider, and talking with a provider about prostate cancer screening tests were all positively associated with screening status. In the physician survey, most physicians recommend screening to their average-risk male patients. Three-fourths (74%) of physicians discussed benefits and risks of PSA testing with their patients; but few used educational tools. Only 35% discussed the side effects of prostate cancer treatment with their patients. The rates of screening reported by men were relatively high, given that current recommendations promote informed decision making rather than universal screening. The majority of physicians recommend prostate cancer screening to their patients, with few decision-making tools used. All relevant information may not be provided in the discussion. These results point to the need for increasing informed decision making about prostate cancer screening.

Introduction

Prostate cancer is the most common form of cancer (excluding skin cancers) among men in the United States. In 2009, it is estimated that 218 890 new cases were diagnosed and that 27 050 men died from prostate cancer.[1] The two primary prostate cancer screening tests are the PSA test and digital rectal examination (DRE). PSA is a blood test and is publicly available at a reasonable cost (est $20–40 per test). DRE is a manual examination of the prostate through the rectum and is conducted as an additional examination for enlarged prostate. The primary goal of prostate cancer screening is to discover clinically significant disease early in the disease process in order to prevent morbidity and mortality through treatment.[2,3]

According to the United States Preventive Services Task Force and the American College of Preventive Medicine, there are currently insufficient data to recommend for or against routine screening among men at average risk of prostate cancer.[3–5] Instead, men are advised to learn about the benefits and risks of early detection modalities and match them with their values to make informed decisions about whether or not to undergo screening through a process of considering the issues and their own personal views and priorities.[4] Recommendations from the American Urological Association are that prostate cancer screening be ‘offered’ to age-eligible men; these guidelines also include language about discussing the risks and benefits and alignment of choices with personal values and goals with a physician before deciding whether to screen.[6] These recommendations indicate that prostate screening is not a simple choice and that men need to be supported in making informed decisions about whether to obtain screening.[7]

Decision making has been described as a process by which patients can consider relevant information and values to make decisions about procedures that are not medically recommended.[7] Informed decision making involves patients considering the pros and cons of a specific screening test and the resulting activities, considering the options together with personal values, and making a decision. An emphasis upon dialogue and collaboration between clinician and patient is called shared decision making.[8,9] Although shared decision making has been discussed since the early 1980’s, it is relatively new in preventive cancer care. If we apply this model to decisions about prostate cancer screening, then communication and information exchange between patient and provider could be an important factor in the final decision to obtain testing.

Several variables have been noted in the literature to be related to the decision to obtain prostate cancer screening, including personal and individual variables such as knowledge and broader social ecological variables, such as institutional and provider variables.[10] For example, prostate check up and symptom knowledge was low in both African American and Caucasian men.[11] Beliefs varying by culture and ethnicity of surveyed men were important in how they approached prostate cancer screening and treatment.[12] These data indicate that men without information and ways to make sense of that information are at risk for being unable to make an informed decision about whether to get screened for prostate cancer. The other half of the relationship, the interaction with provider, is also important, in that access to a provider was a key variable in predicting prostate cancer screening, independent of demographic variables.[11] The provider has an important role in screening decisions; provider communication style, provider encouragement and provider sharing information with the patient all were significantly and positively related to screening.[10] Providers often have knowledge and attitudes that influence their abilities to assist patients in medical decisions. Unfortunately, discussions about decisions do not happen as frequently as desired; patients do not report accurate and extensive conversations with their provider about screening.[13] These data point to the need to identify both patient- and provider-level variables that help us understand how and why men receive prostate cancer screening.

The purpose of the present study is to identify and compare the prostate cancer screening behaviors of patients and providers in a similar geographic area. We were able to examine state-wide survey data on men’s self reports of screening and data from primary care physicians in Washington state. This comparison will perhaps shed light on the similarities and differences in the views of these two groups and will provide direction for future intervention to improve the shared decision-making process.

Study 1

Patient Reports of Prostate Cancer Screening

Methods. Survey Procedures: We used data from the Washington State Behavioral Risk Factor Surveillance System (BRFSS), a collaborative project of the Centers for Disease Control and Prevention (CDC) and US states and territories. The BRFSS is an ongoing data collection program designed to measure behavioral risk factors in the adult population (18 years of age or older) living in households, via a telephone survey of a probability sample of all households with telephones in the state. The interviewing process used computer-assisted telephone interviewing. Interviewer performance was monitored for quality. Telephone interviewing was conducted during each calendar month, and calls were made 7 days per week, during both daytime and evening hours. Standard procedures were followed for rotation of calls over days of the week and times of day. BRFSS procedural rules are described on their website.[14,15] The response rate using CASRO methods was 43%, with a cooperation rate of 69%.

Survey Data: We conducted analyses on the prostate cancer screening module of the BRFSS data for 2004, focusing on prevalence rates for current prostate cancer screening (defined as PSA screening, and/or DRE screening within the past year). All men ages 40 and over were asked whether they had ever had PSA or DRE, and if yes, when the most recent test occurred. These items are part of the BRFSS core cancer screening measures and were developed and tested at CDC. Men were also asked whether they had ever discussed prostate cancer screening tests with their health care provider. This item was developed and pre-tested by the Washington State Department of Health BRFSS team. Due to current guidelines for average-risk men, we restricted our analysis to men age 50 and older.

Analyses presented in this report were performed using SUDAAN 9.0, (Research Triangle Institute, NC, USA) so that we could account for the BRFSS’ sample design and weighting and obtain rates representative of Washington’s population (Washington also conducts the BRFSS with a much larger sample than most states: even restricting our analyses to men age 50 and older, our analyses include 2840 men). Prevalence estimates were calculated using the ‘final weight’ calculated for each participant. The final weight indicates the number of people in the Washington population of men ages 50 and older represented by each observation. Participants with ‘don’t know’ or ‘refused’ responses were excluded from analyses.

Prevalence rates and confidence intervals were calculated (a) overall, (b) by age, (c) by race, (d) by education level, (e) by income level, (f) by marital status, (g) by rural/urban commuting area, (h) by insurance coverage, (i) by whether participants had a personal health care provider and (j) by whether participants had talked with their provider about prostate cancer screening tests. We then conducted multivariate logistic regression models, with current prostate cancer screening as the outcome variable. We calculated adjusted prevalence ratios from the odds ratios, using Zhang and Yu’s methods for calculating risk and prevalence ratios from multivariate analyses of common behaviors.[15]

Results

A total of 1680 men, or 59.63%, reported current prostate screening. Table 1 presents prostate screening rates by demographic group. Men with household incomes <$20 000 per year and between $20 000 per year and $49 000 per year were less likely to have current prostate cancer screening than men with the highest household incomes. Widowed men were less likely to report prostate cancer screening than coupled men. The majority of men in this sample did possess health insurance of some kind; men with insurance were much more likely to be screened than men without any insurance. Similarly, most of the men reported that they had a personal doctor and were more likely to report screening if they had a personal doctor. More than half of the men had spoken with their health care provider about a prostate cancer screening test, and these men were much more likely to be screened than men who had not had this discussion with their healthcare provider. However, a significant minority of men who had not discussed screening tests with their healthcare provider (43.30%) reported either a PSA test or a DRE in the past year.

Study 2

Provider Reports of Prostate Screening Recommendations

Methods. Sample: The authors obtained a mailing list of primary care physicians in Washington state from the Washington State Medical Association. This mailing list included physicians from the following specialties: family practice, general practice, internal medicine and obstetrics/gynecology (physicians identifying obstetrics/gynecology as their specialty did not answer survey questions about prostate cancer screening and will not be discussed further). The list included names and contact information for 5125 physicians practicing in Washington state. Power calculations revealed that a sample of 700 physicians (assuming a 70% response rate) would have sufficient power to estimate physicians’ screening knowledge, attitudes and behaviors with confidence intervals of ±5%. A simple random sample of 700 names was drawn from this list with a random number generator.

Procedures: Gilmore Research Group (GRG), a survey research company that conducts quantitative and qualitative research studies, administered the survey in November and December 2004. All physicians in the sample received a notification letter via fax; this letter described the survey and explained that a survey package would arrive the following day in an overnight-mail envelope. The survey package included: a cover letter explaining the survey, the survey itself, a check for $50.00 as an incentive to participate and a pre-paid overnight return envelope.

Physicians had the option to complete the survey by using the paper copy mailed to them, or by using an online version available on the World Wide Web (the cover letter included access information). GRG mailed reminder postcards to physicians who had not yet completed the survey at 2 and 4 weeks post the initial mailing. Physicians who had not completed the survey after a month received telephone follow-up. The procedures and survey were reviewed by the Washington State Institutional Review Board before fielding the survey.

Survey Questionnaire: The survey questionnaire included four sections: (1) recommendations for colon cancer screening, (2) colon cancer screening performance and follow-up, (3) practice and personal characteristics and (4) prostate cancer screening practices (Sections 1 and 2 are not relevant to this paper and will not be described further). The prostate cancer screening section of the survey included items measuring physicians’ current recommendations for prostate cancer screening, and several items assessing whether risks and benefits associated with screening are discussed with patients, and whether informational tools are used during the discussion (brochures and so on). These items were adapted from a survey of providers in the literature or created by the study team.[16]

The Washington Comprehensive Cancer Control Partnership Prostate Cancer Task Force (which includes cancer survivors, academics, physicians and members of community organizations) provided feedback on early drafts of the survey questionnaire and suggested additional items. GRG pre-tested the survey with four physicians; they all found the survey questionnaire easy to understand and were able to complete it in 10–15 min. Their comments were incorporated into the final version of the survey questionnaire (available from the authors on request).

Statistical Analyses: We used descriptive statistics and contingency tables with χ2-tests to analyze physicians’ screening knowledge, attitudes and practices. These analyses were stratified by the primary care specialties included in the study. We also conducted a multivariate logistic regression analysis to determine which physician characteristics are associated with good informed decision making practice for PSA testing. As in Study 1, we calculated adjusted prevalence ratios and present these in place of odds ratios.

Results

Response Rate. Of the 700 physicians in the sample, 92 (13%) were not eligible to participate (most commonly due to not having an active practice or not self-identifying as a primary care physician) and 53 (8%) were not reachable at the contact information provided in the mailing list. Of the 555 remaining physicians, 397 completed the survey, 11 refused and 147 did not respond, resulting in a response rate of 69% (assuming that all non-responders were eligible; dividing non-responders into eligible and ineligible categories resulted in a 74% response rate). Most of the participants (351; 88%) completed the paper survey. The remaining 46 participants (12%) completed the survey online (analyses revealed only minor differences in physician responses by survey mode).

Physician Sample Characteristics. Most of the physicians in the survey were family practitioners (N=214). Very few physicians described their specialty as general practice (N=15), and these were grouped with family practitioners for all analyses. The other physicians described their specialty as internal medicine (N=116), resulting in a final sample of 345 physicians (excluding the 52 obstetrician/gynecologists who completed the survey, but not the prostate screening items). Most of these physicians were in single-specialty practices (64%), with most physicians (82%) in urban locations.

Most of the physicians were male (69%) and white (83%). Time since completing medical school was fairly evenly distributed, with 15% completing medical school less than 10 years ago, 32% completing 10–19 years ago, 33% completing 20–29 years ago and 20% completing 30 or more years ago.

Physician Recommendations and Informed Decision-making Practices. Most of the physicians reported recommending DRE (90%) and PSA (83%) to average-risk male patients. Most physicians recommended beginning testing during the mid-forties (M start age=45 for DRE and 48 for PSA). Only 37% of physicians reported that they stopped performing DRE at a given age (M stop age=79 years), and 52% reported stopping PSA (M stop age=78 years). Most of the physicians (74%) reported that they ‘always or almost always’ discuss the risks and benefits of PSA testing; about half (52%) reported that they always/almost always discuss risks and benefits of prostate cancer screening when they perform DRE. Very few physicians (10%) reported always using any materials to discuss prostate cancer screening. Physicians were most likely to report use of written materials, with 37% reporting use of written materials sometimes and 9% always or almost always. Very few physicians used videotapes and websites.

Table 3 summarizes physicians’ reports of the topics they address when discussing PSA tests. Physicians were likely to report discussion of issues about the PSA test’s performance characteristics, such as efficacy in detecting prostate cancer and the possibility of false-positive results (64% ‘very likely’ to discuss). Most physicians did not report discussion of ‘downstream’ issues, such as the possible side effects of treatment for prostate cancer (35% ‘very likely’ to discuss).

Table 3. Proportion of physicians reporting issues they discuss when deciding whether to order PSA tests

Family practice (N=229) Internal medicine (N=116)
Efficacy of PSA in detecting prostate cancer 68.42% (62.08–74.15) 53.91% (44.74–62.83)
Efficacy of PSA in reducing mortality from prostate cancer 56.39% (49.84–62.72) 52.63% (43.44–61.65)
PSA may prompt further tests that may not reveal cancer 65.79% (59.37–71.68) 59.48% (50.29–68.05)
Anxiety may occur while waiting for results or taking more tests 32.89% (27.08–39.28) 24.14% (17.19–32.78)
Prostate cancer may not cause significant morbidity if untreated 55.95% (51.82–62.30) 59.48% (50.29–68.05)
Efficacy of treatment options for prostate cancer 35.68% (29.70–42.15) 34.78% (26.62–43.95)
Possible side effects of treatments for prostate cancer 34.36% (28.45–40.80) 35.65% (27.41–44.84)

Note: 95% confidence intervals in parentheses. Percentage reflect physicians saying they ‘always or almost always’ discuss the issue. Remaining response options were ‘unlikely’ and ‘somewhat likely’ to discuss. Physicians’ responses were approximately equally divided across the three response options for discussing treatment efficacy and side effects of treatment for prostate cancer, and anxiety that may occur while waiting for results. For other issues, the majority of responses (80% or more) fell into either ‘somewhat likely’ or ‘very likely’ to discuss.

About half of the physicians (55%) collect family history information for prostate cancer for 75% or more of their male patients. Given that family history is a significant risk factor for prostate cancer and should inform individual men’s prostate cancer screening decisions, it is surprising that many physicians do not routinely collect this information from their patients.

Associations with Prostate Cancer Screening Best Practices. For these analyses, we defined best practice as always or almost always discussing the risks and benefits of prostate cancer screening when deciding whether to order PSA, because of the clinical guidelines (for example, American Cancer Society[2] and American Urological Association[6]). In this sample of primary care physicians, 74% reported always or almost always using best practices, with 21% sometimes and 5% rarely or never using best practices.

Table 4 presents use of best practices for prostate cancer screening by physician background and characteristics. Physician specialty was the only characteristic associated with best practice in this model. Family practitioners were more likely to always discuss risks and benefits than internal medicine physicians.

Discussion

Most men are screened, and more men are screened for prostate cancer than for colorectal cancer (total screening rate with either PSA or DRE=59.63%; only 55.89% of this sample reported fecal occult blood test in the past year, flexible sigmoidoscopy in the past 5 years, or colonoscopy in the past 10 years). This is concerning, considering the conflicting recommendations for prostate cancer screening and the lack of recommendations to screen by most recommending bodies. Reports of screening follow the demographic patterns presented in the literature in other studies, in that low income and minority men in general are screened less. In addition, these disadvantaged men report talking with their provider about prostate cancer screening less frequently than do men with more resources, indicating a possible mechanism for differences in screening rates.

How does this relatively high screening rate match with the recommendation from the provider? It seems that men are getting screened, in part, because providers are recommending the screening. The rates of provider recommendations, according to provider reports, are quite high and are one possible cause of screening in the majority of men. A higher proportion of general internists recommended screening, suggesting that guidelines might be better known among internal medicine physicians. On the other hand, family practice physicians are more likely to discuss the risks and benefits of PSA tests with their patients.

The second disturbing finding is that providers don’t use decision-making materials or aids when providing recommendations to patients. The simple recommendation from providers to get screened (without cautions and caveats) might be the reason for the high rate of screening reported in men. The process of shared decision making is complex, and most providers report lack of skills and knowledge for this process.[17] Furthermore, most physician visits are very brief, and physicians may find the time required to explain the risks and benefits of PSA testing prohibitive. Using shared decision-making tools and materials might help, although few providers currently do so. A sizable number of men report obtaining prostate screening without discussing it with their physician. From our data we do not have a clear picture of how screening is obtained in this situation, but the patients could have been simply saying that no decision-making discussions occurred when they requested or were offered screening.

Of particular note is the relatively high screening rate among men over 80, higher than for the youngest men in our sample. This relatively high proportion of older men who are obtaining screening is in contrast to the recent debates about the appropriateness of considering life expectancy when screening older men.[18] Given that the minor burden of screening is often followed by more invasive tests and treatments, we should consider whether screening for prostate cancer that is not likely to result in mortality is wise at older ages.

There are several limitations to the present study that somewhat curtail its applicability to a larger population. First, the response rate to the BRFSS is problematic at 43%, bringing the potential for selection bias in the survey and calling into question the representativeness of the existing responses. Second, the providers sampled are not a direct match for the patients surveyed, and this would have made for stronger conclusions about the role of providers in screening for prostate cancer. Third, these data are bounded by geography and time, and therefore might not be relevant to other settings.

Where shall we go from here? We are far from meeting the recommendations that discussions about the risks and benefits of prostate cancer screening occur between patient and provider before deciding whether to obtain prostate cancer screening. Providers must be better engaged in the framing of prostate cancer screening as a decision, not a conclusion. National policy guidelines indicate that prostate cancer screening needs to be approached as a decision of the patient, not as a goal for patient behavior. So, continuing to work with physicians to improve their decision-facilitating skills with patients is one direction. Physicians are faced with an increasing array of new screening and treatment options that have complicated risks and benefits, so increased skills in shared decision making should serve them well beyond the topic of prostate cancer screening.

Wide provision of existing tools and materials to help in the decision-making process might be another direction for future research. Creating opportunities for patients to learn the facts about prostate screening outside of the provider visit might make that visit more productive and useful to both physician and provider. These tools range from complicated written packages available online from home, to paper guides that can be distributed by physicians at their offices (for example, CDC guides), to easy-to-use electronic tools that could be installed in provider offices to be used before a visit. These tools might be an efficient way to increase the shared decision-making activities that occur about prostate cancer screening without creating extra burden for primary health care providers.

if nothing lasts forever then why is love the exception....outkast

What do you think about this “review” of my book by someone on Amazon?

An informative book if the reader is trying to decide between radiation or
surgery only. But if you want to explore other avenues like Hormone Therapy as
well as Traditional Chinese Medicine and other alternative modalities, there is
no info at all. This is strictly a prostate cancer surgeon talking about which
one of these treatment options he eventually chose.

The reviewer is right in some respects…my book is limited primarily to the two most common modalities of treating prostate cancer in the USA. This was the intent…take a very complicated decision and go about showing ways to arrive a decision that would be best for the individual taking into consideration the risks of each modality and the specifics of the prostate cancer.

It was not meant to be an “end all do all” but “an arrow in one’s quiver” and that is stated in the book.

Another thing it does is focus on the abnormal urinary symptoms inherent to each of the treatments and why that is important to consider in any prostate cancer treatment decision.

Well he gave me 3 stars and now I am below 5 stars…boo hoo hoo!

Can someone throw me a bone and if you found my book helpful write a review for amazon…but not for who you’d think?  The reviews I feel really do help the newly diagnosed prostate cancer in their journey to the decision that best suits them. Reviews tell the reader  a bit about the reviewer (this reviewer is an alternative medicine type) but issues that were important to him and this in turn clues the newly diagnosed patient into issues that may be relevant to them.

Finally, hormones are used not for cure and hence don’t have a role in the person making “the decision.” They are used occasionally by the radiation therapist as an adjunct but not as primary treatment option unless the disease is metastatic or the patient’s underlying health dictates its use.

Don’t know much about Chinese remedies for prostate cancer.

better to live on the corner of the roof, than to share a house with a nagging wife...proverbs

North Georgia is known for being in the foothills of the Blue Ridge Mountains and for the small streams associated with that. The state fisheries department “stocks” the streams with Rainbow trout that they raise at various hatcheries. The state then takes them by truck and empties the fish into the small streams at bridge crossings. The “locals” know when the trucks are coming or they keep a look out for them and when they see them go by they follow them to see when and where they are stocking. They call their friends and get their rods and corn and go and catch the stocked fish often times depleting the trout before the unsuspecting or “un enlightened” can get there. I have fished out West many many years and out there the streams have native trout and lots of room for your fly line to flip about to put a fly where the fisherman wants. In north Georgia, the streams are small, they are stocked, and there is little room for the traditional fly fishing techniques. There are some spots on bigger streams with a wide area that can be fished like out West but they are not common. Some folks have bought sections of a river or stream, stocked it with Rainbows, fed them, and then let people for a price come in and fish for them. Big fish, still stocked, still not native, somewhat of a contrived fly fishing experience but an experience non the less for a price and pictures of the experience. The customer can now say that he dressed up like a fly fisherman, used a fly rod and has a picture of him and big fish held by the guide (they won’t let you touch the fish) to prove it.

I have attempted to catch stocked fish on many occasions. The limit is about 6 and they actually taste very good, the majority are about 8-10 inches long. They are raised on corn and so the locals will put corn on a hook with a worm and let it float naturally on the bottom to catch the trout. The locals will deplete the hole and by the time someone like me gets there the trout are few and far between. The rarely use fly rods for the purpose preferring an ultralight Zebco with 4 lb test to flip to the holes in tight spaces. I have been at a small stream to catch one of these stockers and have seen men from Atlanta all duded up in a $350 Orvis wading outfit, $500 fly rod and standing near a small hole with no room to cast and the line just sitting three feet in front with a fly. Unfortunately, I have never been very successful in catching stocked trout, regardless of the fishing device, or lure, or bait used. It’s not really a natural pursuit anyway and I think my heart is really not into it….especially when you see a guy in overalls and fishing with a Walmart rod and worm just killing the fishing and leaving with a stringer by the time I get there.

Now quickly, Chattahoochee Shoal Bass, like the one shown above. The perfect solution to fishing in North Georgia, using a fly rod or reel, and having plenty of room to fish…just like out west but no limitations to the size constraints of the river and no “stock fishing people” with corn around. These fish live in and about rocks, eat and behave very similar to trout, but are native, fight well and are in the Chattahoochee at its more northern distribution. I can but my flies or lures in a pocket of my shorts, get my fishing kayak and a cooler, and fish the whole river by going from rock to rock and getting out when I want using a rock in the middle of the river as a fishing platform or fish from the kayak. I can take my dog, I don’t need waders, a shirt, a tackle box, fishing at its most simplistic and finest nature.

The fish above was caught by casting a black worm to a rock cliff and letting the worm fall off the rock into the water to the immediate strike of the “shoalie.” Penelope, our Chocolate Lab, jumped in after it as well after it was hooked and swam around trying to catch the line and made the whole process of landing the fish that more interesting. I tried to film it but elected to just catch it and take pictures. We own one of the little cabins in the background, it was in one of these that I wrote a large portion of my book, and from the steps is where me and Penelope swam across to the rocks to fish. It don’t get no better than this, and all I need for an occasion like this is one fish. That supplies me adequately for my “fish fix.”

Now….Can you get cancer from having sex with a man or husband who has prostate cancer? Well…I hope not.

Recent comment on this blog by the wife of a prostate cancer patient:

You don’t know that there is no communicability of prostate cancer cells. There are many instances of cancers being spread by virus-like antigens; leukemias, cervical cancers– and there are some indications that a retrovirus may be involved with prostate cancer. In 2006, researchers associated a previously unknown retrovirus, Xenotropic MuLV-related virus or XMRV, with human prostate tumors. This retrovirus may very well travel between human beings.
That there are no direct links discovered as yet between prostate cancer patients and cancers found in their sexual partners certainly does not preclude those links ever being found. Your flippant dismissal of the legitimate fears of communicability (i.e. “so, good try girls” etc.) are insulting to women who are caught in this terrible situation with the men they love.
Shame on you.

The person’s comments above I think are well spoken and made me do some thinking and re-research on links between the male with prostate cancer giving the female he may have sex with cancer (she could not get prostate cancer, so we have to assume any question regarding this is getting a cancer in general…women don’t have a prostate and prostate cancer is a cancer of prostate cells).

I could not find any articles in the Journal of Urology that addressed the subject and all the “googled” references to the question made no link between the male with prostate cancer and the female. This excercise did prompts some thoughts and maybe more addresses the issue from a practical or pragmatic perspective.

  • Take any man that has been diagnosed with prostate cancer. It is not as if he got cancer the very moment he was diagnosed. Just like other cancers, the disease has been in the body long before the diagnosis was made. So for the male with the “diagnosis” of prostate cancer, he has been having sex with his wife for possibly years before the diagnosis was made, but yet having it in his body. What are we to do about this possibility?
  • Since 1 in 6 men ultimately get prostate cancer, should all concerned women have their men biopsied for prostate cancer before having sex with them. Not very practical and this is why I have elected to view this from a “common sense” approach as opposed to “well it is possible that a link will be found one day.”
  • If it is spread would it be through saliva? Would it be the cells and viruses in the sperm? Sperm would seem more reasonable-again most men have had prostate cancer years before it is diagnosed? Would a condom fix this? Should this be a recommendation of fearful women afraid to catch cancer from their husband-before or after the diagnosis is made?
  • Something to ponder…if cancer is spread from the man’s sperm…then for the man that has been treated for prostate cancer by a radical prostatectomy-he has no ejaculate. So is the man without a prostate who has prostate cancer but no ejaculate…is he safer for the female not getting cancer than the man who has prostate cancer but not diagnosed but has a “communicable ejaculate?”
  • Men who have been treated with radiation with time have little if any ejaculate…not because the prostate has been removed but the gland has been “dried up” by the radiation.
  • What kind of cancer would the female get? It won’t be prostate. Since the prostate is an “adenocarcinoma” or a cancer of a gland, would the female get a glandular cancer or just any cancer. This would work if the male suppressed the females immune system and then she’d be susceptible to any cancer?
  • Could a male get cancer from a female if she has breast cancer? They both have breasts.
  • And on and on and on….

Now to being flippant and insulting to women caught in this terrible situation (married to a man with prostate cancer-like my wife is):

  • I sincerely apologize if my response offended…I may too often try to use irreverent humor to make points…
  • The “good try girls” is a male thing and too was made in jest about the trite stigma of women trying to get out of having sex i.e. the old headache or menses thing. I again apologize for that…meant to be funny not insulting.
  • I believe that if a wife is concerned about catching cancer from her husband who has prostate cancer (by the way…having cancer and having been treated for prostate cancer are two different things-if you are treated and there is no evidence of disease i.e. negligible PSA then you don’t have cancer-you “had” it) the stress by worrying about catching cancer is a greater drag on her well-being than the chances of getting a cancer. My wife will correct me any time I say or imply that I have prostate cancer. “John you don’t have cancer.”
  • There is a difference, I would think, between the wife of a man with prostate cancer that has failed the initial treatment and has recurrent prostate cancer and the wife of the man who has been treated, most probably cured and has no evidence of residual disease.
  • I think it would make the wife of the man, who had prostate cancer that has spread  to his bones, think more about the possibility of the communicable nature of prostate cancer. So I feel it is a legitimate concern or question.

Summarizing…I am sorry to offend…I want to helpful in these issues and be clever with it in a knowledgeable way but not be “doctorish.” Take all with a grain of salt. Thinking about this issue…if you could spread cancer where would it end, look at all the cancers out there each with their own “virus” to spread and how that would affect relationships.

I think the reason this comes up more with prostate cancer than with other cancers is this…sperm. Subconsciously the female may be thinking that the fluid comes through the prostate and carries with it cells that then touch her tissues and then the possibility of getting cancer.

Well…it has never been shown, but as the commentor correctily states…”just because it hasn’t been proven that there isn’t a link doesn’t mean there isn’t one”…agreed.

So you men out there trying to get out of having sex because you have prostate cancer…sorry-not a good excuse…. Just kidding…..
