[Results of surgical treatment of stage I non-small cell lung cancer].
Results of surgical treatment of 152 cases of stage I non-small cell lung cancer from 1985 to 1989 are reported. The 1, 3, 5-year survival rates were 92.1%, 74.5%, 64.6%, respectively. Among 152 cases, there were 100 squamous carcinoma, 44 adenomatous carcinoma and 8 squamous and adenomatous mixtures. There were 50 cases of T1 N0 M0 and 102 of T2 N0 M0 according to TNM staging. Of the 152 cases, 46 were discovered by regular physical check-up without symptoms and 106 by patient complaints. 130 cases underwent lobectomy, 14 cases pneumonectomy, and 8 cases sectional or wedge cut. Comparison of the 5-year survival rate after the operation was: T1 N0 M0 > T2 N0 M0; squamous > adenomatous; lobectomy > pneumonectomy (P > 0.005); cases detected by regular check-up > those with symptoms (P < 0.005). The 5-year survival rate of stage I lung cancer was 64.6%. There is no difference from the result of those in 1960s and 1970s. More effective combination therapy is needed to increase the survival rate.
