RESUMO

OBJECTIVE: This study aimed to evaluate the prognostic impact of age at diagnosis, and pretreatment hematologic markers, including lymphocyte percentage and the neutrophil-to-lymphocyte ratio (NLR), in patients with locally advanced cervical cancer (LACC) treated with definitive radiotherapy (RT). METHODS: A total of 392 patients with LACC (stage IIb to IVa) treated with cisplatin-based concurrent chemoradiotherapy or RT alone between 2001 and 2012 were retrospectively enrolled. Clinical data and pretreatment complete blood counts were extracted from electronic medical records of the patients, and analyzed. Treatment outcomes, progression-free survival (PFS), and overall survival (OS) were evaluated. RESULTS: Low lymphocyte percentage and a high NLR were associated with younger age, advanced stage, larger tumor size, lymph nodes metastasis, and treatment failure. The cut-off value for lymphocyte percentage and NLR was determined using a receiver operating characteristic curve. In univariate analysis, low lymphocyte percentage (≤24%) was associated with poor PFS and OS, while high NLR ( > 2.8) was significantly associated only with PFS. In multivariate analysis, both lymphocyte percentage (hazard ratio [HR], 0.59; 95% confidence interval [CI], 0.40–0.85; P=0.005) and NLR (HR, 1.55; 95% CI, 1.07–2.25; P=0.022) had independent prognostic value for PFS. Compared to younger patients (age ≤50 years), older patients (age > 60 years) had a lower risk of death. CONCLUSION: Although the lymphocyte percentage did not remain significant in multivariate analysis for OS, it was predictive of PFS and OS. Thus, lymphocyte percentage is a simple hematologic parameter with a significant prognostic value in patients with LACC treated with definitive RT.

RESUMO

Objective:To investigate the feasibility of detecting excision repair cross-complementing 1(ERCC1)and ERCC2 in peripheral venous blood instead of cancer tissues from esophageal squamous cell carcinoma patients. Methods:The expressions of ERCC1 and ERCC2 mRNA were detected by using RT-PCR in 39 cases of peripheral venous blood samples, esophageal squamous cell carcinoma tissues, and adjacent normal tissues. ELISA was used to determine the levels of ERCC1 and ERCC2 proteins in serum. The periphe-ral blood from 10 healthy volunteers was used as control. Results:Expression levels of ERCC1 and ERCC2 mRNA and protein were significantly higher in peripheral blood from healthy control than those in esophageal carcinoma patients (P<0.05). There was a positive correlation between the expression of ERCC1 and ERCC2 mRNA in peripheral blood and cancer tissues (P<0.01). Conclusion:The expression levels of ERCC1 and ERCC2 mRNA in peripheral blood can indirectly reflect their expression levels in human esophageal squamous cell carcinoma tissues.
