Background: The objectives of this study were to determine the frequency of metastatic (M1) prostate cancer (PC) at presentation in different age groups, to examine the association of age with PC-specific mortality, and to calculate the relative contribution of different age groups to the pool of M1 cases and PC deaths. Methods: Records from 464,918 patients who were diagnosed with PC from 1998 to 2007 were obtained from the Surveillance, Epidemiology, and End Results (SEER) database. The patients were categorized according to age into groups ages < 50 years, 50 to 54 years, 55 to 59 years, 60 to 64 years, 65 to 69 years, 70 to 74 years, 75 to 79 years, 80 to 84 years, 85 to 89 years, and ≥ 90 years. The cumulative incidence of death from PC was computed using the Gray method. Results: The frequency of M1 PC at presentation was 3% for the group aged < 75 years, 5% for the group ages 75 to 79 years, 8% for the group ages 80 to 84 years, 13% for the group ages 85 to 89 years, and 17% for the group aged ≥ 90 years. The 5-year cumulative incidence of death from PC was 3% to 4% for all patients with PC in any category aged < 75 years, 7% for patients ages 75 to 79 years, 13% for patients ages 80 to 84 years, 20% for patients ages 85 to 89 years, and 30% for patients aged ≥ 90 years. Although patients aged ≥ 75 years at PC diagnosis represented just over a quarter (26%) of all PC cases, they contributed almost half (48%) of all M1 cases and more than half (53%) of all PC deaths. Conclusions: Compared with younger patients (aged < 75 years), older patients were more likely to present with very advanced disease, had a greater risk of death from PC despite higher death rates from competing causes, and contributed more than half of all PC deaths. Awareness of this issue may improve future outcomes for elderly patients with PC.
Sexual desire and arousal difficulties are often correlated in women. However, no studies have examined characteristics of women with clinically diagnosed hypoactive sexual desire disorder (HSDD) that increase the likelihood of co-occurring arousal difficulties. The authors examined combined HSDD and arousal/ lubrication problems using baseline cross-sectional data from the HSDD Registry for Women. Their analyses were restricted to women who could be classified with certainty as having arousal or lubrication difficulties by the Female Sexual Function Index (requiring sexually activity in the past 4 weeks). Results showed that among 426 premenopausal women with HSDD, 50.2% had arousal problems, 42.5% lubrication problems, 39.0% combination, and 46.2% neither. Among 174 postmenopausal women, prevalence percentages were 58.0% arousal, 56.9% lubrication, 49.4% combined, and 34.5% neither. The strongest predictor of combined arousal/lubrication problems was self-reported severity of HSDD. Among premenopausal women, race/ethnicity, depression, and lower relationship happiness were also associated with combined arousal/lubrication problems. Among postmenopausal women, surgical menopause and use of selective serotonin reuptake inhibitors were positively associated with arousal problems. Arousal and lubrication problems were present in approximately half of this subsample of HSDD Registry participants, with distinctions in prevalence and predictors by menopausal status and type of arousal difficulty (arousal vs. lubrication).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
