BACKGROUND & OBJECTIVE: Non-small cell lung cancer(NSCLC) is characterized by high incidence and poor prognosis in our country. New prognostic factors are needed to guide the treatment of patients with NSCLC. This study was designed to evaluate the characteristics and outcome in NSCLC patients who underwent completely surgical resection.
A total of 423 cases were analyzed using SPSS10.0 software. The survival differences were compared by univariate and multivariate analysis.
The 5-year survival rate in this group was 46.98%. Multivariate analysis identified two poor prognostic factors: advanced TNM stage (P=0.003) and blood group B (P=0.02). Multivariate analysis also identified two better prognostic factors:adjuvant chemotherapy (P=0.04) and squamous histological type (P=0.005). The number of the risk factors (blood group B and non- squamous) were negatively related to prognosis according to multivariate analysis in stage III a NSCLC (the 5-year survival rates:43.5% vs 23.7% vs 4.0%, P< 0.001).
Adjuvant chemotherapy maybe is beneficial to NSCLC patients who underwent completely surgical resection. Cox multivariate analysis demonstrates that evaluation of both histological type and blood-group has a significant prognostic effect in stage IIIa patients.
