Abstract
Background and objective There is insufficient evidence on the oncologic risks of testosterone therapy for men with prostate cancer managed with active surveillance. We carried out a retrospective study to assess the effect of testosterone therapy on oncologic outcomes for men on active surveillance for prostate cancer. Methods Surveillance, Epidemiology and End Results (SEER)-Medicare linked data were used to identify men diagnosed with prostate cancer from 2008 to 2017 who were managed with active surveillance and received testosterone (n = 167) or no testosterone (n = 6658) therapy. Outcomes included conversion from active surveillance to active treatment (radical prostatectomy, cryotherapy, radiation, or androgen deprivation therapy), prostate cancer-specific mortality, and overall mortality. Statistically significant factors on univariable analysis were included in a Cox proportional-hazards regression model for multivariable analysis. Key findings and limitations The median age was 71 yr (interquartile range [IQR] 68-74) in the testosterone group and 72 yr (IQR 69-75) in the no-testosterone group, with corresponding median follow-up after prostate cancer diagnosis of 5.2 yr (IQR 3.4-7.8) and 4.7 yr (IQR 3.2-6.9). There were no prostate cancer-specific deaths in the testosterone group and 39 (0.6%) in the no-testosterone group. Testosterone therapy was not associated with conversion to active treatment (hazard ratio [HR] 0.66, 95% confidence interval [CI] 0.46-0.97; p = 0.033) or overall mortality (HR 1.02, 95% CI 0.68-1.53; p > 0.9). Conclusions and clinical implications In the first population-based, nationally representative study of testosterone therapy for men on active surveillance for prostate cancer, testosterone therapy did not increase the risk of conversion to active therapy or worsen mortality. Prospective studies are needed to confirm these findings. Patient summary For men on active surveillance for prostate cancer, we assessed the effect of testosterone therapy. We found that testosterone therapy did not increase the risk of proceeding to active therapy or of death from prostate cancer.

Abstract
Background Statin therapy has been shown to reduce mortality in a wide range of cancer types and overall stages. Still, there is uncertainty about its efficacy in increasing survival among advanced cancer patients. Methods We conducted a meta-analysis with data from all studies that compared the hazard ratio of overall survival, cancer-specific survival, and progression-free survival in patients with advanced-stage cancer who receive statin therapy. Studies were selected from the PubMed, Embase, and Web of Science databases from their inception to December 31, 2022. Cancer types are limited to those rarely screened during the annual examination and more likely to develop into advanced stages, such as lung, pancreatic and ovarian cancers. This resulted in 27 studies eligible for meta-analysis. Results Statin therapy was associated with a 26% decreased risk of overall survival (HR, 0.74; 95% CI, 0.67, 0.81), 26% decreased risk of cancer-specific survival (HR, 0.74; 95% CI, 0.61-0.88), and 24% decreased risk of progression-free survival (HR, 0.76; 95% CI, 0.65-0.87) for advanced-stage cancer patients. The associations were not attenuated or reinforced by study design, study regions, cancer types, or other medical care. Concomitant use of other anticancer medications did not result in confounding effects. Conclusions Statin therapy produces significant benefits on overall survival and cancer-specific survival. Although the benefits might be lower than the approved immunotherapy medications, its cost-effectiveness could lead to dramatic health consequences. Concomitant use of statin drugs as cancer treatments is highly recommended in future clinical trials.

Association of Statin Use with the Risk of Incident Prostate Cancer: A Meta-Analysis and Systematic Review. JOURNAL OF ONCOLOGY 2022; 2022:7827821. [PMID: 36561541 PMCID: PMC9767737 DOI: 10.1155/2022/7827821] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Revised: 11/12/2022] [Accepted: 11/28/2022] [Indexed: 12/14/2022]
Abstract
Background With the growth and aging of population, the incidence of prostate cancer will increase year by year, which is bound to bring greater economic burden to the society. There has been greater interest in the anticancer effects of statin in recent years. It is controversial whether statin use is associated with the risk of prostate cancer (PCa). Thus, we conducted a meta-analysis and systematic review to explore the effects of statin use and their duration and cumulative dose on the overall incidence of PCa. Method The study was conducted according to the latest guidelines for PRISMA 2020. We searched PubMed and other databases for studies about the association of statin use with the risk of incident prostate cancer between January 1, 1990, and April 11, 2022. Two independent researchers extracted data and evaluated the quality of the studies. R x64 4.1.2 and random-effects model were used for data statistics. Relative risk (RR) and odds ratio (OR) effective values with a 95% confidence interval (95% CI) were used to assess the main results. Results The results of 6 RCT and 26 cohort studies showed that statins did not significantly associate with the incidence of PCa (RR = 0.94, 95% CI: 0.82-1.08). The similar results were obtained from 9 case-control studies (OR = 1.03, 95% CI: 0.99-1.07). However, statins were associated with a lower risk of Pca (RR = 0.44, 95% CI: 0.28-0.70) when the cumulative defined daily dose (cDDD) was high. Using statins for more than five years could be associated with a reduced incidence of Pca (RR = 0.47, 95% CI: 0.23-0.97). There was a significant heterogeneity in these studies (RCT and cohort study: I 2 = 98%, P < 0.01; case-control study: I 2 = 72%, P < 0.01). Conclusion We concluded that statins had a neutral association with the overall risk of PCa. High cDDD and long duration were associated with a lower risk of PCa.

Statin Use Is Associated with Better Prognosis of Patients with Prostate Cancer after Definite Therapies: A Systematic Review and Meta-Analysis of Cohort Studies. JOURNAL OF ONCOLOGY 2022; 2022:9275466. [PMID: 36425939 PMCID: PMC9681552 DOI: 10.1155/2022/9275466] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/16/2022] [Revised: 10/28/2022] [Accepted: 11/01/2022] [Indexed: 03/03/2024]
Abstract
OBJECTIVE Although the prognostic effect of statins on patients with prostate cancer (PCa) has been frequently evaluated, a consistent result is still lacking. We aimed to evaluate the association between statin use and mortality among patients with PCa after definite therapies. METHODS A systematic search of PubMed and other databases for cohort studies about the effect of statins on patients with PCa was performed until April 2022. Meta-analysis was performed using R software version 4.1.2. RESULTS 24 cohort studies involving 369, 206 participants were finally included. We found statin use significantly reduced the risk of prostate cancer-specific mortality (PCSM) with a pooled hazard ratio (pHR) = 0.76 (95% CI: 0.69-0.84, 18 studies), especially for postdiagnostic statin users: pHR = 0.81 (95% CI: 0.77-0.85) and patients who accepted androgen deprivation therapy (ADT): pHR = 0.69 (95% CI: 0.59-0.81). Statin use was also associated with a 24% reduction in the risk of all-cause mortality (ACM): pHR = 0.76 (95% CI: 0.68-0.85, 17 studies), especially for postdiagnostic statin users: pHR = 0.81 (95% CI: 0.78-0.85) and patients treated with ADT: pHR = 0.72 (95% CI: 0.63-0.82) or radiotherapy (RT): pHR = 0.68 (95% CI: 0.50-0.93). CONCLUSION In conclusion, the use of statins could promote the prognosis of patients with PCa, especially for postdiagnostic users. For patients who received either ADT or radical prostatectomy (RP), statin use could decrease the PCSM. As for those who received either ADT or RT, statin use could decrease the ACM.

Low testosterone and high cholesterol levels in relation to all-cause, cardiovascular disease, and cancer mortality in White, Black, and Hispanic men: NHANES 1988-2015. Hormones (Athens) 2022; 21:399-411.

Abstract
PURPOSE The role of testosterone (T) deficiency (T ≤ 300 ng/dL) and hypercholesterolemia (total cholesterol ≥ 240 mg/dL) in the risk of all-cause cardiovascular diseases (CVD) and cancer mortality among a nationally representative sample of non-Hispanic White (NHW), non-Hispanic Black (NHB) and Hispanic men remains poorly understood. METHODS Data included a full sample (NHANES 1988-1991, 1999-2004, 2011-2014) and subset sample (excluding 2011-2012, no estradiol and SHBG levels available) of 5379 and 3740 men, respectively. Participants were aged ≥ 20 y with serum T and cholesterol data (median follow-up 7.6 years). Weighted multivariable-adjusted Cox proportional hazards models were used in this study. RESULTS In the overall population of full and subset samples, hypercholesterolemia was inversely associated with all-cause (HR = 0.76, 95% CI, 0.63-0.91) and cancer mortality (HR = 0.56, 95% CI, 0.34-0.90). Similar findings were observed among NHW men, but higher T levels increased the risk of CVD mortality in the subset sample (T3 vs T1, Ptrend = 0.02). Among NHB men in the full and subset samples, T deficiency increased the risk of CVD mortality, but T3 vs. T1 decreased it (Ptrend = 0.03), and hypercholesterolemia decreased cancer mortality. Among Hispanic men in the full and subset samples, T deficiency increased, and hypercholesterolemia decreased the risk of CVD mortality. CONCLUSION Hypercholesterolemia was inversely associated with cancer mortality. However, higher levels of T were positively associated with CVD mortality among NHW and were inversely associated with CVD mortality among NHB and Hispanic men. Larger prospective studies are warranted to clarify the underlying relationship between T and cholesterol with mortality among racial and ethnic groups.

Joint association of statins and testosterone replacement therapy with cardiovascular disease among older men with prostate cancer: SEER-Medicare 2007-2015. Cancer Epidemiol 2022; 79:102172. [PMID: 35523034 DOI: 10.1016/j.canep.2022.102172] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2022] [Revised: 04/19/2022] [Accepted: 04/26/2022] [Indexed: 11/22/2022]
Abstract
BACKGROUND Use of statins and testosterone replacement therapy (TTh) have been independently linked with prostate cancer (PCa) and cardiovascular diseases (CVD). However, there is a research gap about the joint association of statins and TTh with CVD among PCa survivors and a matched cancer-free cohort. METHODS In SEER-Medicare 2007-2015 (N = 35,990 men), we identified 17,995 PCa survivors, and 17,995 age- and index-matched cancer-free men. Pre-diagnostic prescription of statins and TTh was ascertained for this analysis and examined in two matched cohorts. Weighted multivariable-adjusted conditional logistic regression models were used to evaluate the independent and joint associations of statins and TTh with CVD. RESULTS We found that independently statins (OR = 0.48, 95% CI: 0.44-0.53) and TTh (OR = 0.74, 95% CI: 0.0.61-0.90) were each inversely associated with CVD in the overall sample. TTh plus statins was inversely associated with CVD (OR = 0.50, 95% CI: 0.36-0.70, Pinteraction = 0.03). Similar associations were observed among the matched cancer-free cohort. Among PCa survivors, only statins (OR = 0.62, 95% CI: 0.56-0.68) and combination of TTh plus statins (OR = 0.63, 95% CI: 0.44-0.90) were inversely associated with CVD, but not the independent use of TTh. CONCLUSION Pre-diagnostic use of statins and TTh, independent or in combination, were inversely associated with CVD in the overall and cancer-free populations, but among PCa survivors it was mainly use of statins, not TTh. Greater reduced effects on CVD were observed with statins or in combination with statins, but not with TTh. Future studies need to confirm these associations among older men with aggressive PCa.
