First-degree family history of cancers in patients with stage I endometrial carcinoma. Prevalence and prognostic impact

We aimed to study the impact of first-degree family history on patients with endometrial cancer. We conducted a retrospective chart review from January 1990 to June 2016, comparing stage I endometrial cancer patients with and without a sporadic family history of cancers. We collected the patients' demographic information, tumor characteristics, and treatment plans. During the follow-up period, patient information on tumor recurrence and survival was collected. The chi-square test was used to assess the associations between categorical variables. The Cox proportional hazards regression model was used to estimate multivariate-adjusted hazard ratios (95% confidence interval (CI)). Among the 1737 patients with stage I endometrial cancer, 709 had a positive first-degree family history of cancers and 1028 had negative family history (FH) of cancers. Patients with positive FH were more likely to be older, have stage IB disease, and receive adjuvant radiotherapy; however, the difference was not statistically significant. At 5 years follow up, patients with a positive family history had longer time to recurrence (TTR) than their negative FH counterparts. Maternal family history of cancer was the most common, followed by a sister's history of cancer, paternal history, brother's history, and offspring history of cancer. Breast, endometrial, and colon cancers are the most common cancers among first-degree relatives. Endometrial cancer patients with sporadic first-degree FH of cancers share similar demographics and tumor characteristics compared to their counterpart with slightly increased likelihood to be older, with stage IB disease and have a longer TTR compared to their negative counterpart.

Ethnic, racial, and geographic disparities in endometrial cancer mortality along the US-Mexico border from 1999 to 2020

To investigate ethnic, racial, and geographic disparities in EC mortality trends from 1999 to 2020, focusing on the US-Mexico border. We utilized death certificate data from the CDC WONDER database to analyze EC mortality across racial, ethnic, and geographic groups. Age-adjusted mortality rates (AAMRs) were calculated, and trends were analyzed using Joinpoint regression to determine annual percentage change (APC) and average annual percentage change (AAPC). From 1999-2020, there were 3635 EC-related deaths in border regions and 185,887 in non-border areas. Non-border regions had higher AAMRs (2.54 vs. 2.21 per 100,000), but EC mortality increased more rapidly in border regions (AAPC, 1.35; P < 0.001) than in non-border areas (AAPC, 0.73; P < 0.001). Hispanic women had lower overall mortality (AAMR, 2.04 vs. 2.56 per 100,000) but experienced a faster increase in mortality (AAPC, 1.30 vs. 0.88; P < 0.001) compared to non-Hispanics. Black women had the highest mortality (AAMR, 4.71) and a significant upward trend (AAPC, 1.02; P < 0.001) CONCLUSION: EC mortality disparities are evident across racial, ethnic, and geographic lines, with Hispanic women and border regions showing steeper increases in mortality over time. Black women continue to experience the highest mortality rates. These findings underscore the need for targeted public health interventions to address socioeconomic barriers and improve healthcare access in these vulnerable populations.
