Objective |
We examined the effect of radiation on survival for early-stage uterine carcinosarcomas and leiomyosarcomas.
Study Design |
The surveillance, epidemiology, and end results database was used to identify patients with stage I/II carcinosarcomas and leiomyosarcomas. Logistic regression and Cox models were developed to determine radiation use and survival.
Results |
Among 1819 women with carcinosarcomas and 1088 women with leiomyosarcomas, radiation was administered to 667 of the patients (37%) with carcinosarcomas and to 235 of the patients (22%) with leiomyosarcomas. In a multivariate model, adjuvant radiation reduced the risk of death by 21% in women with carcinosarcomas (hazard ratio, 0.79; 95% CI, 0.7-0.9). Radiation reduced mortality rates in patients with carcinosarcomas who had not undergone node dissection but had only a marginal effect on survival in node-negative women. Adjuvant radiation had no effect on survival for early-stage leiomyosarcomas (hazard ratio, 1.1; 95% CI, 0.9-1.4).
Conclusion |
Adjuvant radiotherapy improves survival for select patients with early-stage carcinosarcomas but is of limited value for leiomyosarcomas.
