Risks of Second Primary Gynecologic Cancers following Ovarian Cancer Treatment in Asian Ethnic Subgroups in the United States, 2000-2016.

ABSTRACT:

Background

The differential occurrence of second primary cancers by race following ovarian cancer is poorly understood. Our objective was to determine the incidence of second primary gynecologic cancers (SPGC) following definitive therapy for ovarian cancer. Specifically, we aimed to determine differences in SPGC incidence by Asian ethnic subgroups.

Methods

We identified 27,602 women ages 20 years and older and diagnosed with first primary epithelial ovarian cancer between 2000 and 2016 who received surgery and chemotherapy in 18 population-based Surveillance, Epidemiology and End Results Program registries. We compared the incidence of SPGC with expected incidence rates in the general population of women using estimated standardized incidence ratios (SIR) and 95% confidence intervals (CI).

Results

The incidence of SPGC was lower among White women (SIR = 0.73; 95% CI, 0.59-0.89), and higher among Black (SIR = 1.80; 95% CI, 0.96-3.08) and Asian/Pacific Islander (API) women (SIR = 1.83; 95% CI, 1.07-2.93). Increased risk of vaginal cancers was observed among all women, although risk estimates were highest among API women (SIR = 26.76; 95% CI, 5.52-78.2) and were also significant for risk of uterine cancers (SIR = 2.53; 95% CI, 1.35-4.33). Among API women, only Filipinas had significantly increased incidence of SPGC overall including both uterine and vaginal cancers.

Conclusions

Risk of SPGC following treatment of ovarian cancer differs by race and ethnicity, with Filipina women having the highest rates of second gynecologic cancers among Asian women.

Impact

Ensuring access and adherence to surveillance may mitigate ethnic differences in the early detection and incidence of second gynecologic cancers.

Project description:ImportanceNotable increases in mortality from alcohol-induced causes over the past 2 decades in the United States have been reported. However, comprehensive assessments of trends in alcohol-induced mortality by sex, age, race/ethnicity, and social and geographic factors are lacking.ObjectiveTo examine trends in alcohol-induced mortality rates from 2000 to 2016, comparing results by demographic characteristics including sex, race/ethnicity, age, county-level socioeconomic status, and geographic location.Design, setting, and participantsThis serial cross-sectional study used US national vital statistics data for years 2000 to 2016 for all US residents older than 15 years. Data analysis was conducted from January to September 2019.ExposuresTrends in alcohol-induced mortality by sex, race/ethnicity, age, county-level socioeconomic status (ie, median income, percentage of unemployed residents, percentage of residents with a bachelor's degree), rurality level, and US state.Main outcomes and measuresAlcohol-induced mortality, ie, deaths for which alcohol holds a population-attributable fraction of 1. Deaths were expressed per 100 000 residents as absolute and age-standardized rates. Mortality trends were measured as average annual percentage changes (AAPCs) for the entire period (ie, 2000-2016) and annual percentage changes (APCs) for individual periods of change within the study period.ResultsA total of 425 045 alcohol-induced deaths were identified from 2000 to 2016 (2000: 19 627 deaths; 14 979 [76.3%] men; 2016: 34 857 deaths; 25 213 [73.3%] men). The rate of alcohol-induced deaths increased substantially among men (AAPC, 1.4%; 95% CI, 1.0% to 1.8%) and women (AAPC, 3.1%; 95% CI, 2.6% to 3.6%) and accelerated recently (men, 2012-2016: APC, 4.2%; 95% CI, 3.1% to 5.3%; women, 2013-2016: APC, 7.1%; 95% CI, 5.1% to 9.1%). The largest increases by race/ethnicity were observed among American Indian and Alaska Native men (AAPC, 3.3%; 95% CI, 2.6% to 4.0%), American Indian and Alaska Native women (AAPC, 4.2%; 95% CI, 3.8% to 4.6%), and white women (AAPC, 4.1%; 95% CI, 3.6% to 4.7%). Despite initial declines among black women, black men, and Latino men (eg, Latino men, 2000-2003: APC, -5.1%; 95% CI, -9.8% to -0.1%; 2003-2013: APC, -0.6%; 95% CI, -1.4% to 0.2%), increases occurred later in the study period (eg, Latino men, 2013-2016: APC, 4.1%; 95% CI, 0.3% to 8.1%). The rates of increase varied by age group and in turn by racial/ethnic group. Among white individuals, large absolute increases occurred in midlife (eg, men aged 55-59 years, 2000-2003: 25.5 deaths per 100 000 residents; 2013-2016: 43.3 deaths per 100 000 residents; women aged 50-54 years, 2000-2003: 7.4 deaths per 100 000 residents; 2013-2016: 16.5 deaths per 100 000 residents), although APCs were also large for ages 25 to 34 years, ranging from 4.6% to 6.9% per year among men and from 7.3% to 12.0% among women. Among American Indian and Alaska Native individuals, increases throughout the age range were observed, with the largest absolute increase occurring for ages 45 to 49 years among men (2000-2013: 113.6 deaths per 100 000 residents; 2013-2016: 193.1 deaths per 100 000 residents) and for ages 50 to 54 among women (2000-2013: from 56.1 deaths per 100 000 residents; 2013-2016: 105.1 deaths per 100 000 residents).Conclusions and relevanceThis study found large increases in alcohol-induced death rates across age and racial/ethnic subgroups of the US population, which have accelerated over recent years. Large increases in alcohol-induced deaths among younger age groups may be associated with future increases in alcohol-related disease.

Project description:ImportanceIn the last 4 decades, survival among patients with human papillomavirus (HPV)-associated cancers has improved, while the incidence of these cancers has increased among younger cohorts. Among survivors of HPV-associated cancers, persistent HPV infection may remain a risk factor for preventable HPV-associated second primary cancers (HPV-SPCs).ObjectivesTo investigate the risk of HPV-SPCs among survivors of HPV-associated index cancers and to test the hypothesis that the HPV-SPC risk among these persons has increased over the last 4 decades.Design, setting, and participantsA retrospective cohort study of 9 cancer registries of the Surveillance, Epidemiology, and End Results (SEER) database was conducted to identify patients with HPV-associated (cervical, vaginal, vulvar, oropharyngeal, anal, and penile) cancers diagnosed from January 1, 1973, through December 31, 2014. The dates of analysis were July 1, 2017, to January 31, 2018.Main outcomes and measuresThe HPV-SPC risk was quantified by calculating standard incidence ratios (SIRs) and excess absolute risks (EARs) per 10 000 person-years at risk (PYR). The HPV-SPC risk by time was estimated using Poisson regression.ResultsFrom 113 272 (73 085 female and 40 187 male) survivors of HPV-associated cancers, 1397 women and 1098 men developed HPV-SPCs. The SIRs for HPV-SPCs were 6.2 (95% CI, 5.9-6.6) among women and 15.8 (95% CI, 14.9-16.8) among men. The EARs were 18.2 per 10 000 PYR for women and 53.5 per 10 000 PYR for men. Among both women and men, those who had index oropharyngeal cancers had the highest HPV-SPC risk (SIR, 19.8 [95% CI, 18.4-21.4] and EAR, 80.6 per 10 000 PYR among women; SIR, 18.0 [95% CI, 16.9-19.1] and EAR, 61.5 per 10 000 PYR among men). Women who had index cervical cancers and men who had index anal cancers had the lowest HPV-SPC risk (SIR, 2.4 [95% CI, 2.2-2.7] and EAR, 4.5 per 10 000 PYR among women; SIR, 6.5 [95% CI, 4.7-8.8] and EAR, 18.5 per 10 000 PYR among men). Both women and men who had index HPV-associated cancers of any kind had a significantly higher risk of oropharyngeal HPV-SPCs. Over the last 4 decades, the risk of developing most types of HPV-SPCs after index cervical, vaginal, and vulvar cancers increased.Conclusions and relevanceAccording to this study, the HPV-SPC risk among survivors of HPV-associated cancers is significant, implying that persistent HPV infection at multiple sites may be associated with HPV-SPCs. These findings have the potential to inform surveillance recommendations for survivors of HPV-associated cancers.
