Impact of hemoglobin on survival of young women with cervical cancer treated with concurrent chemoradiotherapy.

Abstract

e17529 Background: Cervical cancer is a global public health problem, with higher impact in many low-income and middle income countries. In Peru, cervical cancer is the leading cause of cancer deaths among women. The aim of this study is to investigate the prognostic factors affecting long-term survival in locally advanced cervical cancer young patients treated with concurrent chemoradiotherapy. Methods: This is a retrospective study of young women with locally advanced cervical cancer who underwent radiotherapy with concurrent platinum-based chemotherapy at the national cancer peruvian institute (INEN), from 2008 to 2012. The clinicopathological factors of all patients were collected. To explore the relationship between factors and prognosis, survival rates were estimated by the Kaplan–Meier method. Results: A total of 192 patients under 35 years old . Among all patients, 167 were diagnosed with SCC, 19 with AC, and 5 with ASC. Most of the patients were IIB and IIIB FIGO stage, 69% and 22% respectively. 38 cases had no metastatic lymph nodes and 42 cases were diagnosed of lymph node metastases, of which 30 were positive for pelvic lymph nodes only, and 12 were positive for para-aortic lymph nodes. We obtained pretreatment hemoglobin levels for all patients and found a median of 111 g/L, also we calculated the Prognostic nutritional index (PNI) with a median of 41.87 that correlates with a moderate to severe malnutrition in patients prior treatment. Response to chemoradiotherapy was not available in 13 patients, 136 achieved complete response, 30 patients with persistent disease and 12 with disease progression. Estimated median OS of all patients was 114.1 months [101.8-126.4] and median DFS was 112.3 months [98.9-125.7]. Exploratory analysis was performed to determine potential prognostic factors, only hemoglobin ≤ 100 g/L was statistically significant (p = 0.007). Conclusions: In young patients undergoing chemoradiation for cervical carcinoma, the hemoglobin prior treatment is prognostically significant.
