e17127 Background: Risk factors for the development of gynecological cancers are known to vary; however, the effect on mortality is uncertain. Methods: Using CDC Wonder Database, death certificate data, all women who died of cancer in the United States from 2003-2016 were included if a cancer diagnosis was listed as a primary or contributing cause. Cases were then divided into gynecological (GYN) cancer or not, and thereafter characterized as cervical, ovarian, uterine, or other. Other causes contributing to death (comorbidities were then captured via ICD10 codes listed on death certificates and grouped into similar disease states. Chi-squared and Mann-Whitney U tests were performed for statistical significance. Results: Of 35,324,091 death certificates, 4,177,823 deaths were women with cancer listed as a cause of death. 440,792 were gynecological cancer, with cervical cancer in 62,807; uterine cancer in 134,420; ovarian cancer in 221,119; and other gynecological cancers in 25,946. Women with GYN cancers were more likely to have intestinal obstruction (2.7% vs 0.7%, OR 4.05), ascites (0.7% vs 0.2%, OR 3.30), HIV (0.1% vs 0.05%, OR 1.53), kidney disease (4.7% vs 3.6%, OR 1.33), and thrombo-embolic disorders (4.3% vs 3.5%, OR 1.25) when compared to non-GYN cancers (all p < 0.00001). Uterine cancer was more likely to have diabetes-related comorbidities (6.4% vs 3.8%, OR 1.75), metabolic syndrome (9.5% vs 6.1%, OR 1.60), thrombo-embolic disorders (5.5% vs 3.8%, OR 1.48), ischemic heart disease (5.0% vs 3.6%, OR 1.43), than other GYN cancers (all p < 0.00001). Cervical cancer was more associated with HIV (0.3% vs 0.03%, OR 10.73) and tobacco-related disorders (4.7% vs 1.9%, OR 2.56). Ovarian cancer was more associated with ascites (1.1% vs 0.4%, OR 2.93), intestinal obstruction (3.5% vs 1.8%, OR 2.04), and pleural effusion (1.1% vs 0.6%, OR 1.92) (all p < 0.00001). Conclusions: Comorbidities contributing to death significantly differ amongst gynecological cancers and non-gynecological cancers, which has relevance to strategies that can be differentially employed to reduce mortality. In particular, women with uterine cancer may benefit from reduction in risk of diabetes, ischemic heart disease, and embolic disorders; those with cervical cancer may benefit from smoking cessation and optimal HIV management.
