Abstract

Objective To determine overall survival (OS) and factors associated with OS of women with Mullerian adenosarcoma. Methods Women with adenosarcoma of the uterus, cervix or ovary (n = 2205) were identified from the 1998–2011 National Cancer Data Base. Kaplan-Meier and multivariate Cox proportional-hazards survival analyses were performed to test for associations of potential explanatory variables with OS. A subset analysis of women with uterine adenosarcoma was also performed. Analyzed confounders included age, insurance status, income, race, surgical margin status, nodal and distant metastasis, surgical procedure type, and treatment with radiation and/or chemotherapy. Results Primary sites were uterus (n = 1884), cervix (n = 229) and ovary (n = 92), representing 0.43% of uterine, 0.16% of cervical, and 0.04% of ovarian cancers in the NCDB. Only 36/1176 (3.1%) and 2.5% (33/1,342) had nodal and/or distant metastasis, respectively, at diagnosis. Distant metastasis, positive surgical margin, increased age, higher composite comorbidity score and adjuvant radiotherapy were independently associated with decreased OS. Primary site, lymph node status, surgical procedure, chemotherapy use, race, insurance status and income quartiles were not significantly associated with OS. Each 1 cm increase in tumor size was associated with increased hazard for death (HR (95% CI) 1.06 (1.01–1.12), p = 0.018) among women with uterine adenosarcoma. Conclusion Complete surgical resection remains the only treatment with well-evidenced OS benefit among women with Mullerian adenosarcoma. Early surgical resection may increase survival of Mullerian adenosarcoma.
