Association between vasectomy and prostate cancer

There was no significant association between vasectomy and prostate cancer-specific mortality (risk ratio, 1.01, 95% CI, 0.93-1.10). Conclusions: This study found that vasectomy was associated with the risk of any prostate cancer and advanced prostate cancer. From the current evidence, patients should be fully informed of the risk of prostate. There was a weak association between vasectomy and any prostate cancer that was closer to the null with increasingly robust study design. This association is unlikely to be causal and should not preclude the use of vasectomy as a long-term contraceptive option Association between vasectomy and advanced prostate cancer (risk ratio, 1.06, 95% CI, 1.01-1.12), low-grade prostate cancer (risk ratio, 1.06, 95% CI, 1.02-1.10), and intermediate-grade prostate.. No association was found between vasectomy and risk of high-grade, advanced, or fatal prostate cancer. Meaning At most, there is a trivial association between vasectomy and prostate cancer that is unlikely to be causal; therefore, concerns about prostate cancer should not preclude the use of vasectomy as an option for long-term contraception

The association for vasectomy was more pronounced in men who were 40 years at the time of vasectomy (HR=2.63; 95% CI 1.40-4.94) than in men who were younger at vasectomy. CONCLUSIONS: The results from this prospective study suggest a positive association between vasectomy and prostate cancer, especially low-grade disease In light of current biologic and epidemiologic knowledge about the association between prostate cancer and vasectomy, the discrepancies found between the results of different studies 1, 15, 16, and the effect of different methodologies on study results, the clarification of this controversy is a highly significant issue

  5. Objective: To evaluate the possible association between vasectomy and prostate cancer.Design: Systematic review of the literature.Patient(s): Fourteen original studies published between January 1985 and December 1996 that addressed the association between vasectomy and prostate cancer.Main Outcome Measure(s): The strength of the association was estimated with the use of a meta-analysis.

Introduction. The possible association between vasectomy and risk of prostate cancer is a major public health concern. Vasectomy is a widespread and extremely effective method of contraception, with an estimated 500,000 American men undergoing the procedure each year (1, 2).Prostate cancer is the most common cancer among United States men, and in 1999 alone, over 179,000 men will be newly. the American Urological Association, or AUA, concluded that vasectomy likely didn't increase prostate cancer risk yet some studies have suggested a connection between vasectomy and prostate cancer, while others have not. This has led to conflicting media reports, confusion, and some lingering concerns

DATA SOURCES The MEDLINE, EMBASE,Web of Science, and Scopus databases were searched for studies indexed from database inception to March 21, 2017, without language restriction. STUDY SELECTION Cohort, case-control, and cross-sectional studies reporting relative effect estimates for the association between vasectomy and prostate cancer were. Concern that getting a vasectomy could lead to prostate cancer flared in 1993 when the Harvard Health Professionals Follow-up Study reported that men who had undergone vasectomies were about one-and-a-half times more likely to develop prostate cancer than men who had not had the operation RELATED: Prostate Cancer: In Search of Predictive Biomarkers for Immunotherapy. The authors concluded that no strong association between vasectomy and prostate cancer can, based on these data, be. During 4,251,863 person-years of follow-up, there was a small association between vasectomy and incident prostate cancer with a hazard ratio of 1.05 (95% CI, 1.01-1.11). However, no significant association was found when looking separately at prostate cancer b Study Closes the Debate on Vasectomy- Prostate Cancer Link. For years, people believed that there was a link between vasectomies and prostate cancer. In the 1980s and 1990s, reports were published noting that there may be a connection between vasectomies and prostate cancer. A team of researchers from the Mayo Clinic in Rochester, Minnesota and.

In a study that included almost 4400 men with prostate cancer, including 641 who had had vasectomy, the procedure was not associated with prostate cancer risk after an average of 15 years of.. Fourteen original studies published between January 1985 and December 1996 that addressed the association between vasectomy and prostate cancer. MAIN OUTCOME MEASURE(S) The strength of the association was estimated with the use of a meta-analysis (DerSimonian and Laird method) Vasectomy and Cancer Risk Some studies have raised questions about a possible relationship between vasectomy (an operation to cut or tie off the two tubes that carry sperm out of the testicles) and the risk of developing cancer, particularly prostate and testicular cancer Conclusions and Relevance: This review found no association between vasectomy and high-grade, advanced-stage, or fatal prostate cancer. There was a weak association between vasectomy and any prostate cancer that was closer to the null with increasingly robust study design

No. While numerous studies have investigated the link, none of them found any evidence that vasectomy increases a person's risk of prostate cancer. For example, a 2008 study in the Journal of Urology, which looked at 1943 men, found that men who developed prostate cancer were no more likely to have had a vasectomy than men who didn't A large study from the American Cancer Society adds to the evidence that vasectomy does not meaningfully increase prostate cancer risk In fact, since 31% of prostate cancer cases detected in the Danish study were advanced at the time of diagnosis, the association of vasectomy and prostate cancer overall warrants a different. Purpose Conflicting reports remain regarding the association between vasectomy, a common form of male contraception in the United States, and prostate cancer risk. We examined prospectively this association with extended follow-up and an emphasis on advanced and lethal disease. Patients and Methods Among 49,405 US men in the Health Professionals Follow-Up Study, age 40 to 75 years at baseline.

The researchers found that the association remained even among men who received regular PSA screening, suggesting the increased risk of lethal cancer cannot be explained by diagnostic bias. It is the largest and most comprehensive study to date to look at the link between vasectomy and prostate cancer The study, a systematic review and meta-analysis including 53 studies, found there was a weak association between vasectomy and prostate cancer, in which vasectomy was associated with a 0.6% increased risk of prostate cancer diagnosis across all of the studies, but was close to zero effect in the well-controlled studies Concern that getting a vasectomy could lead to prostate cancer flared in 1993 when the Harvard Health Professionals Follow-up Study reported that men who had undergone vasectomies were about one-and-a-half times more likely to develop prostate cancer than men who had not had the operation. The study was careful and large, including 10,055 men.

  1. This issue of The Journal includes two reports of cohort studies by Giovannucci et al that find an association between vasectomy and subsequent risk of prostate cancer. 1,2 Both vasectomy and prostate cancer are common and any causal relationship between the two would be important both for individual and public health. Although the studies by Giovannucci et al are of high quality, whether the.

  3. Nine studies reported no association between vasectomy and prostate cancer stage or grade; 98, 102, 104, 107, 108, 114-116 four studies reported at least one statistically significant finding. 91, 96, 113, 106 These subgroup analyses were not appropriate for meta-analysis given different data breakdowns across studies (i.e., different age.
  4. In fact, there is no established biologic rationale for an association of vasectomy with prostate cancer, the authors wrote in the study. With a vasectomy, the vans deferens is cut, blocked.
  5. The association between vasectomy and prostate cancer was more significant for studies conducted in America (RR = 1.18, 95% CI: 0.89-1.56) than in Europe (RR = 0.89, 95% CI: 0.69-1.14). The summary estimates were higher for those with follow‐up ≤10 years than ones with follow‐up for >10 years and for the studies published before 2002.
  6. Purpose Vasectomy is a commonly used form of male sterilization, and some studies have suggested that it may be associated with an increased risk of prostate cancer, including more aggressive forms of the disease. We investigated the prospective association of vasectomy with prostate cancer in a large European cohort, with a focus on high-grade and advanced-stage tumors, and death due to.
  7. A possible positive association between vasectomy and prostate cancer has raised concern since the early 1990s, although the use of vasectomy for male contraception has remained relatively stable [1]. Approximately 500,000 vasectomies are performed annually in the United States [2]. About 12%) of married men have had a vasectomy

Association between prostate cancer and vasectomy. Prostate cancer affects millions of men worldwide. Some studies have reported an increase in the relative risk of prostate cancer in men who. Objective To determine the association between vasectomy and prostate cancer, adjusting for measures of health seeking behaviour. Design Population based matched cohort study. Setting Multiple validated healthcare databases in Ontario, Canada, 1994-2012. Participants 326 607 men aged 20 to 65 who had undergone vasectomy were identified through physician billing codes and matched 1:1 on age. However, this latest and much bigger study found no association between vasectomy and prostate cancer mortality. This latest study analyzed data for 363,726 men in the Cancer Prevention Study II (CPS-II) cohort, of whom 42,015 (11.5%) were determined to have undergone vasectomy. During follow-up (1982 to 2012), 7451 men died of prostate cancer Vasectomy and risk of prostate cancer. Journal of the American Medical Association 2002; 287(23):3110−3115.

Using a nationwide study of 2.1 million Danish men, Husby et al. report the latest epidemiological finding on vasectomy and prostate cancer in this issue of the Journal.Men who underwent vasectomy had a 15% higher risk of prostate cancer overall (95% confidence interval [CI] = 1.10 to 1.20), with similar associations for advanced and nonadvanced-stage cancers Objectives To evaluate the association of vasectomy with prostate cancer. Methods Participants were male members of the CLUE II cohort followed since 1989. On a questionnaire mailed in 1996, the men were asked if they had had a vasectomy and their age at vasectomy. Between 1996 and April 2004, 78 prostate cancer cases were confirmed among the 3373 men who were at least 35 years old at baseline. The largest association reported was between vasectomy and lethal prostate cancer in a sub-group of men highly screened for prostate cancer. As a result of this report, a number of media outlets released articles linking vasectomy to an increased risk of the most lethal kind of prostate cancer and caused anxiety among many of the millions of. The debate over the association between vasectomy and prostate cancer has been lasted about 40 years and there is no sign of stopping. In the present study, we aimed to evaluate whether vasectomy. Researchers analyzed the association between vasectomy and death from prostate cancer among more than 363,000 men age 40 and older in the Cancer Prevention Study II (CPS-II), including more than 42,000 who were determined to have undergone vasectomy. About 7,400 of the men in the study died of prostate cancer over a 30-year period

The Association Between Vasectomy and Prostate Cancer: A

The AUA's Vasectomy Guideline Panel concluded in 2012 that there is no association between vasectomy and prostate cancer or other significant health risks. The committee's 2012 guideline also says there is no need for physicians to routinely discuss prostate cancer in their preoperative counseling of vasectomy patients There was also an association with age, seen between prostate cancer and vasectomy. Compared with men who had not had undergone the procedure, those who did so when they were younger than the median age were at a significantly increased risk for prostate cancer (HR, 1.18; 95% CI, 1.03 - 1.35) Given the differences between men who do and do not utilize vasectomy, selection bias appears likely to explain any identified association between vasectomy and prostate cancer. Conclusions. With over 20 years of follow‐up, no convincing relationship between vasectomy and prostate cancer of any grade was identified According to the authors, they paid particular attention to study quality and set out to determine if there is an association between vasectomy and any prostate cancer, high-risk prostate.

Abstract. Epidemiological cohort studies investigating the association between vasectomy and prostate cancer risk have yielded inconsistent results. The aim o During that time, 6,023 cases of prostate cancer were diagnosed among the men, including 811 fatal cases. Several studies have looked at the association between vasectomy and prostate cancer.

Vasectomy and Cancer Risk. Some studies have raised questions about a possible relationship between vasectomy (an operation to cut or tie off the two tubes that carry sperm out of the testicles) and the risk of developing cancer, particularly prostate and testicular cancer.Such a relationship, if proven, would be of importance because about 1 in 6 men over age 35 in the United States has had a. To further emphasize this point, far stronger data showing a correlation between prostate cancer (exceptionally more common than PPA) and vasectomy was evaluated by the World Health Organization in 1993, and this organization concluded that 'no known biological mechanism existed to explain any possible association between vasectomy and. Do vasectomies increase the risk of prostate cancer and dementia? A handful of studies in the early 1990s reported an association between vasectomy and prostate cancer, but a conclusive survey in.

Introduction. There have been some front page articles recently stating vasectomy increases the risk of prostate cancer. This has been based on a recent study by the Journal of Clinical Oncology. It observed, that men with a vasectomy have a higher risk (19 in 1000 rather than 16 in 1000) to develop aggressive prostate cancer and that young men. Prostate cancer is the most common cancer in American men and the second leading cause of cancer-related death in American men, after lung cancer.

Vasectomy and the risk of prostate cancer in a prospective

TUESDAY, July 18, 2017 (HealthDay News) -- For men who have had or might undergo a vasectomy, there is good news: A major study finds scant evidence that the procedure raises their risk of prostate cancer. At most, there is a trivial association between vasectomy and prostate cancer that is unlikely to be causal, concluded a team led by Dr. R. Jeffrey Karnes, of the Mayo Clinic in Rochester. However, a population-based, case-control study including men with newly diagnosed prostate cancer showed no association between prostate cancer and vasectomy (relative risk = 0.94),30 and a meta. However, several studies showed that vasectomy was associated with testicular cancer[8,9] and prostate cancer[10,11]. This association especially caught the public's attention because o Accordingly, the association between vasectomy and prostate cancer is of concern and needs further assessments, especially in preclinical models. We have previously demonstrated that semenogelin-I, a major structural protein in human semen, induces prostate cancer progression via functioning as an androgen receptor co-activator [ 27 , 28 , 29.

However, there was a weak association between vasectomy and any prostate cancer that was closer to the null with increasing robust study design. This means that since the man has already visited urologist for vasectomy procedure, chances are he will return to urologist for prostate specific antigen testing The first association between prostate cancer and vasectomy was reported by Honda et al 24 in a population-based case-control study in 1988. They found that the risk of prostate cancer was higher in men who had been vasectomized, and this risk increased with the number of years since vasectomy (the relative risk [RR] for prostate cancer 30. A history of a vasectomy was associated with a 10% increase in prostate cancer overall, and relative risk was 22% higher for high-grade prostate cancer (defined as prostate cancer with a Gleason score between 8 and 10). Analyses suggested that the association of vasectomy with lethal prostate cancer was not linked to differences in sex hormone. The American Medical Association has been sharing updated information concerning the lack of a link between vasectomy procedures and prostate cancer. The findings were published in the Journal of Clinical Oncology and were based on a study that followed participants from 1982 to 2012

Several studies have looked at the association between vasectomy and prostate cancer. It is well known that men who have had a vasectomy are more likely to be seen more frequently by urologists in follow-up than men who never had a vasectomy, and will undergo more frequent PSA testing, he said The results confirmed those of a study by the American Cancer Society. The latter had found no correlation between vasectomy and prostate cancer. The study also found that there was no significant correlation between vasectomy and the overall risk of prostate cancer, the risk of high-grade prostate cancer, or the death rate from the disease vasectomy and high -grade prostate cancer and lethal prostate cancer (RR, 1.22 and 1.19, respectively). There was no apparent association between vasectom y and low -grade or localized prostate cancer. Conclusions: Vasectomy may be associated with a slight increased risk of high -grade or lethal prostate cancer
