Objective: Uterine serous carcinoma (USC) is a rare diagnosis but associated with high mortality. There is limited data to guide adjuvant treatment decisions in early stage disease. The purpose of this study is to evaluate the impact of adjuvant therapy on recurrence-free survival (RFS) and overall survival (OS) in early stage USC.

The CDC Social Vulnerability Index (SVI) integrates scores for four neighborhood-based SDOH domains (socioeconomic status, household characteristics, minority status, and housing type/transportation) to assess neighborhood social vulnerability (NSV). While NSV has been associated with overall cancer mortality and lung, breast, colon, and endometrial cancer-specific mortality, the relationship between NSV as defined by the SVI and ovarian cancer outcomes remains unknown.

Methods: The National Cancer Database was queried to identify all patients with clinical stage III endometrial cancer who had undergone pre-operative chemotherapy as first course of treatment followed by hysterectomy with or without lymph node dissection between the years 2004 and 2020. Univariable and multivariable models were performed to investigate prognostic factors on overall survival.
Article Synopsis
- Elevated allostatic load (AL), which reflects cumulative physiological stress, is linked to increased mortality in various cancer patients, but its connection to ovarian cancer mortality was previously unknown.
- This study analyzed data from 201 ovarian cancer patients to examine the relationship between high allostatic load and overall survival, using a robust statistical model to assess outcomes.
- Results indicated that high allostatic load significantly correlated with increased mortality risk in ovarian cancer patients, suggesting it could be a useful marker for identifying those in need of additional socioenvironmental support during treatment.
Purpose: The purpose of this study was to evaluate RB1 expression and survival across ovarian carcinoma histotypes and how co-occurrence of BRCA1 or BRCA2 (BRCA) alterations and RB1 loss influences survival in tubo-ovarian high-grade serous carcinoma (HGSC).
Experimental Design: RB1 protein expression was classified by immunohistochemistry in ovarian carcinomas of 7,436 patients from the Ovarian Tumor Tissue Analysis consortium. We examined RB1 expression and germline BRCA status in a subset of 1,134 HGSC, and related genotype to overall survival (OS), tumor-infiltrating CD8+ lymphocytes, and transcriptomic subtypes.
