Temporal trends in cardiovascular burden among patients with prostate cancer receiving androgen deprivation therapy: a population-based cohort study.

ABSTRACT:

Background

Although androgen deprivation therapy (ADT) is associated with cardiovascular risks, the extent and temporal trends of cardiovascular burden amongst patients with prostate cancer receiving ADT are unclear.

Methods

This retrospective cohort study analyzed adults with PCa receiving ADT between 1993-2021 in Hong Kong, with follow-up until 31/9/2021 for the primary outcome of major adverse cardiovascular events (MACE; composite of cardiovascular mortality, myocardial infarction, stroke, and heart failure), and the secondary outcome of mortality. Patients were stratified into four groups by the year of ADT initiation for comparisons.

Results

Altogether, 13,537 patients were included (mean age 75.5 ± 8.5 years old; mean follow-up 4.7 ± 4.3 years). More recent recipients of ADT had more cardiovascular risk factors and used more cardiovascular or antidiabetic medications. More recent recipients of ADT had higher risk of MACE (most recent (2015-2021) vs least recent (1993-2000) group: hazard ratio 1.33 [1.11, 1.59], P = 0.002; P_trend < 0.001), but lower risk of mortality (hazard ratio 0.76 [0.70, 0.83], P < 0.001; P_trend < 0.001). The 5-year risk of MACE and mortality for the most recent group were 22.5% [20.9%, 24.2%] and 52.9% [51.3%, 54.6%], respectively.

Conclusions

Cardiovascular risk factors were increasingly prevalent amongst patients with prostate cancer receiving ADT, with increasing risk of MACE despite decreasing mortality.

Project description:BackgroundAndrogen deprivation therapy (ADT) worsens glycaemic control and cardiovascular outcomes. The prognostic value of visit-to-visit HbA1c variability (VVHV) has been unexplored in prostate cancer (PCa) patients receiving ADT.ObjectiveTo explore the effect of ADT on VVHV and the cardiovascular prognostic value of VVHV.Design setting and participantsPCa patients receiving ADT in Hong Kong between January 1, 1993 and March 31, 2021 were included in this retrospective cohort study. Those with fewer than three HbA1c results available within 3 yr after ADT initiation, <6 mo of ADT, missing baseline HbA1c, prior diagnosis of any component of major adverse cardiovascular events (MACEs), and MACEs occurring within 3 yr were excluded. Patients were followed up until September 31, 2021.Outcome measurements and statistical analysisThe outcome was MACEs (composite of heart failure, myocardial infarction, stroke, and cardiovascular mortality). VVHV was calculated from HbA1c levels within 3 yr after and, separately where available, before ADT initiation using coefficient of variation (CV; standard deviation [SD] divided by mean) and average real variability (ARV; average difference between consecutive measurements).Results and limitationsAltogether, 1065 patients were analysed (median age 74.4 yr old [interquartile range 68.3-79.5 yr]). In 709 patients with VVHV available before and after ADT initiation, VVHV increased after ADT initiation (p < 0.001), with 473 (66.2%) and 474 (66.9%) having increased CV and ARV, respectively. Over a median follow-up of 4.3 yr (2.8-6.7 yr), higher VVHV was associated with a higher risk of MACEs (adjusted hazard ratio [per SD] for CV 1.21 [95% confidence interval: 1.02, 1.43], p = 0.029; ARV 1.25 [1.06, 1.48], p = 0.008). Limitations included residual confounding and selection bias.ConclusionsIn PCa patients receiving ADT, VVHV increased after ADT initiation. Higher VVHV was associated with an increased risk of MACEs.Patient summaryIn prostate cancer patients receiving androgen deprivation therapy (ADT), glycaemic control is less stable after initiating ADT, which was associated with an increased cardiovascular risk.

Project description:BackgroundThis study aimed to examine the associations between the use of statins concurrent with androgen deprivation therapy (ADT) and the risks of mortality in Asian patients diagnosed with prostate cancer (PCa).MethodsAdult patients (≥18 years old) diagnosed with PCa who were receiving any form of ADT and were being treated at public hospitals in Hong Kong from December 1999 to March 2021 were retrospectively identified, with follow-up conducted until September 2021. Patients who had received medical castration for <180 days without subsequent bilateral orchidectomy, those who had used statins concurrently with ADT for <180 days, and those with missing baseline total cholesterol levels were excluded. Statin users were defined as individuals who had used statins for ≥180 days concurrent with ADT, while non-users were those who had not used any statins. PCa-related mortality was the primary outcome, while all-cause mortality served as the secondary outcome. Inverse probability treatment weighting was employed to balance the covariates.ResultsA total of 4920 patients were included, consisting of 2578 statin users and 2342 non-users (mean age 76.1 ± 8.2 years). Over a mean follow-up period of 4.2 ± 3.3 years, it was observed that statin users had significantly lower risks of both PCa-related mortality (weighted hazard ratio [wHR] 0.56 [95% confidence interval (CI) 0.48, 0.65], p < 0.001) and all-cause mortality (wHR 0.57 [95% CI 0.51, 0.63], p < 0.001), regardless of the type of ADT used. Notably, these associations were more pronounced among patients with less advanced PCa, as indicated by the absence of androgen receptor antagonist or chemotherapy usage (p value for interaction <0.001 for both outcomes).Conclusion(s)The use of statins concurrent with ADT was associated with reduced mortality risks among Asian patients with PCa. These findings suggest the need for additional research to explore the potential role of statins in the treatment of PCa patients.

Project description:PurposeThis study aimed to explore the existing literature on frailty experienced by patients with prostate cancer (PC) receiving androgen deprivation therapy (ADT).Materials and methodsDatabase and manual searches were conducted to identify relevant studies published in English, with no limitation on the year of publication, according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews guidelines. Four databases-PubMed, Cochrane Library, EMBASE, and CINAHL-were used for database searches and reference lists, related journals, and Google Scholar were used for manual searches.ResultsA total of 12 studies were analyzed for this scoping review. Of these, only 2 were intervention studies, and 1 was a randomized controlled trial. Among the two intervention studies, the multidisciplinary intervention program, including psychological counseling, nutritional coaching, and supervised group physical exercise did not show significant improvement in frailty. In contrast, high-dose vitamin D supplementation significantly decreased frailty. The conceptual and operational definitions of frailty used in each study varied, and the most used one was mainly focused on physical functions. As a result of analyzing the other health-related variables associated with frailty in patients with PC receiving ADT, age, metastases, comorbidities, and incident falls were related to a high frailty level. As for the physiological index, high levels of C-reactive protein, and interleukin-6, and fibrinogen, low levels of total testosterone, lymphocyte count, and creatinine were associated with a high level of frailty. A few studies explored the relationship between psychological and cognitive variables and frailty.ConclusionsFurther research related to frailty in patients with PC receiving ADT should be conducted, and effective interventions to manage frailty should be developed. Additionally, research that considers not only the physical domain of frailty but also the psychological, cognitive, and social domains needs to be conducted.
