Abstract

AbstractObjectiveTo evaluate the effect of different local treatment strategies on survival outcomes in patients with Stage IVB cervical squamous cell carcinoma (SCC) and adenocarcinoma.MethodsPatients diagnosed with Stage IVB cervical SCC and adenocarcinoma between 2004 and 2015 were included from the Surveillance, Epidemiology, and End Results (SEER) database. Subgroup analysis was performed in those diagnosed between 2010 and 2015 and available for the sites of distant metastases.ResultsIn total, 706 patients were identified in this study, including 378 (53.5%) and 328 (46.5%) diagnosed in 2004–2009 and 2010–2015, respectively. There were 525 (74.4%) and 181 (25.6%) patients with SCC and adenocarcinoma, respectively. Moreover, 274 (38.8%) and 432 (61.2%) patients received hysterectomy and primary radiotherapy, respectively. The results of the multivariate Cox regression analysis showed that histology and local treatment strategies were not related to cause‐specific survival (CSS) and overall survival. In the SCC patients, patients who received primary radiotherapy had similar CSS (P = 0.312) and overall survival (P = 0.390) compared with those treated with surgery. In the adenocarcinoma patients, those who received primary radiotherapy had inferior CSS (P = 0.003) and overall survival (P < 0.001) compared with those treated with surgery. Similar results were found in those diagnosed 2004–2015 and 2010–2015 after propensity score matching.ConclusionsFor patients with Stage IVB cervical cancer who received local therapy, surgery, and primary radiotherapy had similar survival in cervical SCC, whereas surgery had better survival outcomes compared with primary radiotherapy in those with cervical adenocarcinoma.
