Abstract

Abstract Men with favorable-risk prostate cancer (PCa) undergoing active surveillance (AS) often seek lifestyle modifications that may reduce their risk of disease progression. We assessed the association between alcohol intake and biopsy upgrading during AS. In this prospective observational study, we included 1,505 men (median follow-up 3.5 years) who were diagnosed with grade group (GG) 1 PCa during 2005–2023 and upon AS enrollment completed a questionnaire estimating alcohol consumption during the preceding 5 years, which we categorized as <1, 1-6, and ≥7 drinks per week. Multivariable competing risk proportional hazards regression was utilized to evaluate self-reported alcohol intake for association with upgrading to ≥GG2 and extreme upgrading to ≥GG3 on a surveillance biopsy, adjusting for baseline clinicopathological prognostic factors, smoking history, and body mass index. Increased alcohol consumption was positively associated with upgrading to ≥GG2 (p¬ for linear trend = 0.008). Compared to <1 drink per week, consumption of ≥7 drinks per week was associated with a 47% increase in the risk of upgrading (subdistribution hazard ratio 1.47, 95% confidence interval 1.16–1.85). No significant association was found between alcohol consumption and extreme upgrading. Our findings identify alcohol consumption as a potentially modifiable lifestyle factor associated with upgrading during AS.

Alcohol is associated with increased risk for several malignancies and is the third leading preventable cause of cancer in the U.S. 1 Although the current U.S. dietary guidelines recommend limiting intake to ≤2 drinks per day for men, a recent Surgeon General’s advisory suggested these limits may still confer cancer risk. 2,3 The relationship between alcohol consumption and PCa remains uncertain, as epidemiologic studies show conflicting results. 4,5 Data in the early-stage PCa AS population are particularly limited. Using one of the largest and longest-running prospective AS cohorts, we examined the association between baseline, self-reported alcohol consumption and PCa grade progression during AS. Our institutional AS Program has monitored men with favorable-risk PCa since 1995. 6 The current study included men in the program who were diagnosed with grade group (GG) 1 PCa between 2005 and 2023, underwent a confirmatory biopsy (typically within 18 months of the diagnostic biopsy) verifying ≤GG1 disease, and upon AS enrollment prospectively completed a questionnaire estimating their alcohol consumption during the 5 years preceding their PCa diagnosis. Institutional Review Board approval and informed consent were obtained from all participants (IRB number NA_00045103). Self-reported alcohol consumption was categorized as: <1 drink per week, 1-6 drinks per week, and ≥7 drinks per week. We evaluated two outcomes: any upgrading (i.e. to ≥GG2) and extreme upgrading (i.e. to ≥GG3) on a surveillance biopsy. Multivariable competing risk proportional hazards regression was used to assess the association between alcohol consumption and each upgrading outcome. Competing events for upgrading during AS included volume reclassification only on a surveillance biopsy triggering treatment, elective treatment, and non-PCa mortality; competing events for extreme upgrading additionally included upgrading to GG2. The regression models adjusted for smoking (current or former smoker versus never smoker), body mass index (BMI), and established AS prognostic factors at baseline including year of diagnosis, age, prostate-specific antigen (PSA) density, number of positive biopsy cores, and maximum percent involvement of a core at diagnosis. 6 A linear contrast was used to assess the linear trend across the alcohol consumption categories by using the median alcohol consumption value for each category. We performed statistical analyses using STATA version 18.0 (StataCorp LLC, College Station, TX). All tests were two sided, with statistical significance set at p <0.05. We included 1,505 men. Self-reported alcohol consumption during the preceding five years is summarized in Table 1 , along with other baseline characteristics. After a median follow-up of 3.5 years (quartiles 1.6–6.2), 515 men experienced upgrading to ≥GG2, including 161 with extreme upgrading to ≥GG3. The cumulative incidence of upgrading was 19% (95% confidence interval [CI] 17%–21%) at 3 years from cancer diagnosis, and 29% (26%–31%) at 5 years; that of extreme upgrading was 6% (5%–7%) at 3 years and 9% (7%–10%) at 5 years. After adjusting for baseline covariates, increased alcohol consumption was significantly associated with an increased risk of upgrading ( p =0.008 for linear trend). Compared with <1 drink per week, consumption of ≥7 drinks per week was associated with a 47% increase in the risk of upgrading (subdistribution hazard ratio 1.47, 95% CI 1.16–1.85). Alcohol consumption was not significantly associated with extreme upgrading ( Table 2 ). In a prospective cohort of over 1,500 men, after adjusting for baseline prognostic factors, smoking history, and BMI, we found that increased self-reported alcohol consumption was positively associated with PCa grade progression during AS. To our knowledge, this is the first prospective study to identify alcohol consumption as a potential risk factor for P­Ca grade progression during AS. The only prior AS study examining alcohol consumption as part of a broader lifestyle analysis found no association with progression, although its small sample size likely limited statistical power 7 . Alcohol consumption was significantly associated with upgrading to ≥GG2, whereas no association was observed with extreme upgrading to ≥GG3. It is likely that true dedifferentiation from GG1 to > GG3 takes longer than to GG2. We have previously shown that extreme upgrading increases significantly with age. 8 Thus, our relatively limited follow-up, and the low number of extreme upgrading events—only 49 men consuming ≥7 drinks/week experienced extreme upgrading—may have reduced our ability to detect an association for this endpoint. Alcohol may exert long-term cumulative effects through pathways such as acetaldehyde mediated DNA damage, oxidative stress, and chronic inflammation, which could plausibly influence progression risk over time among men on AS. 3 Our observation that ≥7 drinks/week was associated with a nearly 50% increased risk of grade progression falls below the U.S. Dietary Guidelines’ recommended limit of ≤14 drinks per week 2 . Instead, our results are consistent with recommendations of the World Health Organization, which emphasize that no level of alcohol consumption is completely risk-free, as even low intake may increase cancer risk. 9 Intake patterns in our cohort are consistent with the general U.S. population, with 4% reporting excessive intake (≥16 drinks/week) and 40% classified as light drinkers (<4 drinks/week), comparable to the Centers for Disease Control and Prevention estimates for older American adults. 10 Strengths of our study include the large sample size, prospective data collection, and rigorous follow-up. Limitations include reliance on self-reported intake, lack of lifetime or post-diagnosis alcohol data, and inability to assess binge drinking patterns. Although we adjusted for smoking, BMI, and established clinical prognostic variables, there may be unmeasured confounding factors inherent to an observational study design. Specifically, lifestyle factors such as diet and exercise may contribute to the observed association between alcohol consumption and biopsy upgrading, but we did not have detailed information on these factors for the entire cohort. In conclusion, in a large prospective cohort, increased self-reported alcohol consumption at baseline was positively associated with PCa grade progression during AS. In particular, consumption of ≥7 alcoholic drinks per week was associated with a significant, nearly 50% increase in the risk of PCa grade progression during AS. No association was observed between alcohol consumption and extreme progression to GG3 or worse disease. Our findings may help inform clinical counseling for men pursuing AS regarding how alcohol consumption relates to their risk of progression. Declarations Funding Sources: None.

After a median follow-up of 3.5 years (quartiles 1.6–6.2), 515 men experienced upgrading to ≥GG2, including 161 with extreme upgrading to ≥GG3. The cumulative incidence of upgrading was 19% (95% confidence interval [CI] 17%–21%) at 3 years from cancer diagnosis, and 29% (26%–31%) at 5 years; that of extreme upgrading was 6% (5%–7%) at 3 years and 9% (7%–10%) at 5 years. \u0026nbsp;\u003c/p\u003e\n\u003cp\u003eAfter adjusting for baseline covariates, increased alcohol consumption was significantly associated with an increased risk of upgrading (\u003cem\u003ep\u003c/em\u003e=0.008 for linear trend). Compared with \u0026lt;1 drink per week, consumption of ≥7 drinks per week was associated with a 47% increase in the risk of upgrading (subdistribution hazard ratio 1.47, 95% CI 1.16–1.85). Alcohol consumption was not significantly associated with extreme upgrading (\u003cstrong\u003eTable 2\u003c/strong\u003e). \u0026nbsp;\u003c/p\u003e\n\u003cp\u003eIn a prospective cohort of over 1,500 men, after adjusting for baseline prognostic factors, smoking history, and BMI, we found that increased self-reported alcohol consumption was positively associated with PCa grade progression during AS. To our knowledge, this is the first prospective study to identify alcohol consumption as a potential risk factor for P­Ca grade progression during AS. The only prior AS study examining alcohol consumption as part of a broader lifestyle analysis found no association with progression, although its small sample size likely limited statistical power\u003csup\u003e7\u003c/sup\u003e.\u003c/p\u003e\n\u003cp\u003eAlcohol consumption was significantly associated with upgrading to ≥GG2, whereas no association was observed with extreme upgrading to ≥GG3. \u0026nbsp;It is likely that true dedifferentiation from GG1 to \u003cu\u003e\u0026gt;\u003c/u\u003eGG3 takes longer than to GG2. We have previously shown that extreme upgrading increases significantly with age.\u003csup\u003e8\u003c/sup\u003e\u0026nbsp; Thus, our relatively limited follow-up, and the low number of extreme upgrading events—only 49 men consuming ≥7 drinks/week experienced extreme upgrading—may have reduced our ability to detect an association for this endpoint. \u0026nbsp;Alcohol may exert long-term cumulative effects through pathways such as acetaldehyde mediated DNA damage, oxidative stress, and chronic inflammation, which could plausibly influence progression risk over time among men on AS.\u003csup\u003e3\u003c/sup\u003e\u003c/p\u003e\n\u003cp\u003eOur observation that ≥7 drinks/week was associated with a nearly 50% increased risk of grade progression falls below the U.S. Dietary Guidelines’ recommended limit of ≤14 drinks per week\u003csup\u003e2\u003c/sup\u003e. Instead, our results are consistent with recommendations of the World Health Organization, which emphasize that no level of alcohol consumption is completely risk-free, as even low intake may increase cancer risk.\u003csup\u003e9\u003c/sup\u003e Intake patterns in our cohort are consistent with the general U.S. population, with 4% reporting excessive intake \u0026nbsp;(≥16 drinks/week) and 40% classified as light drinkers (\u0026lt;4 drinks/week), comparable to the Centers for Disease Control and Prevention estimates for older American adults.\u003csup\u003e10\u003c/sup\u003e\u003c/p\u003e\n\u003cp\u003eStrengths of our study include the large sample size, prospective data collection, and rigorous follow-up. Limitations include reliance on self-reported intake, lack of lifetime or post-diagnosis alcohol data, and inability to assess binge drinking patterns. Although we adjusted for smoking, BMI, and established clinical prognostic variables, there may be unmeasured confounding factors inherent to an observational study design. Specifically, lifestyle factors such as diet and exercise may contribute to the observed association between alcohol consumption and biopsy upgrading, but we did not have detailed information on these factors for the entire cohort.\u003c/p\u003e\n\u003cp\u003eIn conclusion, in a large prospective cohort, increased self-reported alcohol consumption at baseline was positively associated with PCa grade progression during AS. In particular, consumption of ≥7 alcoholic drinks per week was associated with a significant, nearly 50% increase in the risk of PCa grade progression during AS. No association was observed between alcohol consumption and extreme progression to GG3 or worse disease. Our findings may help inform clinical counseling for men pursuing AS regarding how alcohol consumption relates to their risk of progression. \u0026nbsp;\u003c/p\u003e"},{"header":"Declarations","content":"\u003cp\u003e\u003cstrong\u003eFunding Sources:\u0026nbsp;\u003c/strong\u003eNone.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eConflicts of Interest:\u0026nbsp;\u003c/strong\u003eNone.\u0026nbsp;\u003c/p\u003e"},{"header":"References","content":"\u003col\u003e\u003cli\u003e\u003cspan\u003eIslami F, Marlow EC, Thomson B et al (2024) Proportion and number of cancer cases and deaths attributable to potentially modifiable risk factors in the United States, 2019.

We assessed the association between alcohol intake and biopsy upgrading during AS. In this prospective observational study, we included 1,505 men (median follow-up 3.5 years) who were diagnosed with grade group (GG) 1 PCa during 2005–2023 and upon AS enrollment completed a questionnaire estimating alcohol consumption during the preceding 5 years, which we categorized as \u0026lt;1, 1-6, and ≥7 drinks per week. Multivariable competing risk proportional hazards regression was utilized to evaluate self-reported alcohol intake for association with upgrading to ≥GG2 and extreme upgrading to ≥GG3 on a surveillance biopsy, adjusting for baseline clinicopathological prognostic factors, smoking history, and body mass index. Increased alcohol consumption was positively associated with upgrading to ≥GG2 (p¬ for linear trend = 0.008). Compared to \u0026lt;1 drink per week, consumption of ≥7 drinks per week was associated with a 47% increase in the risk of upgrading (subdistribution hazard ratio 1.47, 95% confidence interval 1.16–1.85). No significant association was found between alcohol consumption and extreme upgrading.
