Prognosis of the cavitating non-small cell lung cancer

Abstract

Objective To explore the survival and prognostic status of the cavitating non-small cell lung cancer. Methods A total 42 surgically treated patients with cavitating non-small cell lung cancer were studied retrospectively. Kaplan-Meiei was used to analyze the relationship between the prognostic factors and survival time. The cavitaing non-small cell lung cancer were matched 1:2 to the patients with non-small cell lung cancer that there is no cavity in X-ray, for gender, age, histology, lymph nodes dissection, stage, and whether receiving chemotherapy. The two groups were compared using the Log-rank test. Results The overall 1, 3, 5- year- survival rates for cavitating non-small cell lung cancer were 76.2%, 28.6%, and 14.7%, respectively. The diameter of the cavity and lymph nodes status significantly influenced syrvivals. 1he overall syrvival between the two groups of patients showed no sig- nificant differences (P=0.075). But the factors of women(P=O.040), younger than 60 years(P =0.032), NO of the lymph nodes dissection group(P=0.046), and staging Ⅰ were significantly influenced 5-year survivals(P=0.048). Conclusion The diameter of the cavity and lymph nodes status were correlated with the survival. The carcinomatous cavity are important prognosis factors for the nan-retail cell lung cancer patients of younger than 60 years, negative of lymph nodes dissection and staging Ⅰ , but whether the carci- nomtous cavity are important prognosis factors for the non-small cell lung cancer patients of woman was not determined.
