BACKGROUND: Radiotherapy (RT) is effective in cervical cancer; radiation-induced lymphopenia correlates with poor survival outcome in several cancer types. We investigated the association of total lymphocyte count (TLC) with survival outcomes in patients with cervical cancer. METHODS: We retrospectively reviewed 168 patients with cervical cancer initially treated with definitive RT. We obtained clinicopathological data and TLCs before RT and at the end and at 6 months after RT. Patient-, treatment-, and tumor-specific factors were evaluated to determine their predictive values for overall survival. The association of overall and progression-free survivals with lymphopenia at each point was evaluated. RESULTS: Median follow-up duration was 44 (interquartile range: 25-67) months. Median TLCs before RT and at the end and at 6 months after RT were 1625/mm3, 400/mm3, and 800/mm3 (interquartile range: 1270-1930/mm3, 290-550/mm3, and 600-1067/mm3), respectively. For overall survival, in addition to FIGO stage, body mass index, histology, treatment, and presence of para-aortic lymph node metastasis, lymphopenia at 6 months after RT was a poor prognostic factor in multivariate analysis (P = 0.0026; hazard ratio [HR], 3.06; 95% confidence interval [CI]: 1.48-6.33). For progression-free survival, TLCs before and at 6 months after RT were poor prognostic factors in univariate analysis (P = 0.0318 and 0.0081, respectively); however, the latter was the only independent prognostic factor in multivariate analysis (P = 0.0021; HR, 2.67; 95% CI: 1.43-4.99). CONCLUSION: Post-RT persistent lymphopenia could be a poor prognostic factor for patients with cervical cancer who receive RT.
