Potential epidemiologic risk factors evaluated included obesity, age, parity, race, smoking, oral contraceptive pill and/or hormonal replacement therapy use, and previous hysterectomy or surgery on fallopian tubes and/or ovaries. Additional factors included stage, extent of debulking, residual disease, and disease status.Results Eighty-one patients were identified, and pathologic diagnosis was independently confirmed. Median age at diagnosis was 56 years (range, 21–86 years). Thirty-four percent were obese, and 80% had optimally debulked disease. Forty-six percent were alive, 14% with disease, whereas 25% were dead of disease, 2% died of intercurrent disease, and 27% had an unknown status. In a univariate analysis, optimal surgical debulking was associated with improved progression-free survival (P = 0.01), disease-specific survival (P = 0.03), and overall survival (OS) (P < 0.001) and body mass index with worse OS (P = 0.05). On multivariate analysis, obesity (hazard ratio, 2.8; 95% confidence interval, 1.05–7.3; P = 0.04) and optimal tumor debulking (hazard ratio, 0.05; 95% confidence interval, 0.008–0.29; P = 0.001) were a significant predictor of OS.Conclusions In a multivariate analysis, obesity and optimal tumor cytoreduction were significant predictors of OS. However, obesity was not associated with worse disease-specific survival, suggesting that mortality of obese patients with LGSC may result from other comorbidities. Interventions addressing obesity may improve survival for women diagnosed with LGSC, and further study is warranted to address the role of obesity in LGSC. ER -
