The objective of this study was to confirm whether hemoglobin (Hb) levels during chemoradiotherapy are associated with survival in patients with locally advanced cervical carcinoma and to assess impact of the Hb level on survival according to lymph node (LN) metastasis. A retrospective review of 85 cervical carcinoma patients treated with concurrent chemoradiotherapy was conducted. The stage of disease ranged between FIGO stage IB and stage IVA. Disease-free and overall survivals were evaluated by univariate and multivariate analyses. After median follow-up of 35.7 months, 24 patients developed recurrence of disease and 14 patients died from their disease. Stage, LN metastasis, and squamous cell carcinoma antigen and Hb levels during chemoradiation were correlated significantly with survival (P < 0.05). Maintenance of Hb above 10.0 g/dL was associated with better survival (P < 0.05). However, no such benefits were observed in patients with LN metastasis by magnetic resonance imaging (MRI). Multivariate Cox regression hazard model showed that Hb levels during chemoradiation were an independent prognostic factor in patients without LN metastasis by MRI. Maintenance of Hb during chemoradiation is of benefit in cervical carcinoma patients without LN metastasis but not with LN metastasis by MRI.
