Objectives: In most patients, stage IVB cervical cancer is incurable, and the outcomes are poor. There is significant individual variation in patients with stage IVB cervical cancer, in whom standard treatment has not been well defined. This study aims to review the outcomes and discuss treatment strategies in patients with stage IVB cervical cancer.
Methods: From January 1, 1992, to December 31, 2011, we retrospectively reviewed the data of patients with stage IVB cervical cancer who were given a diagnosis at the Department of Gynecology of the Cancer Institute Hospital.
Results: A total of 111 patients were enrolled. At the time of analysis, the median overall survival (OS) was 16.6 months (range, 0.2-120.9 months), and the 5-year OS rate was 20.2%. The 5-year OS rate was 59.4% for those with only para-aortic lymph node metastases; 24.8% for those with lymphogenous metastases, excluding those with only para-aortic lymph node metastases; 6.1% for those with hematogenous metastases; and 0% for those with disseminated metastases. The OS in patients with lymphogenous metastases was better compared with that of those with either hematogenous or disseminated metastases (P < 0.0001). In multivariate analysis, the performance status, site of metastases (only lymph node or other metastases), and local stage were all independent prognostic factors.
Conclusions: We determined performance status, site of metastases (only lymph node or other metastases), and local stage as independent prognostic factors in patients with stage IVB cervical cancer. Regarding treatment, we confirmed that the effectiveness of chemotherapy was also of significance.
