[Evaluation of prognostic factors in early lung cancer].
We evaluated the prognostic factors in 52 cases of resected early lung cancer: hilar early lung cancers 9 cases and peripheral early lung cancers 43 cases. All hilar lesions were squamous cell carcinoma, and peripheral lesions were adenocarcinoma (31 cases), squamous cell carcinoma (10 cases), large cell carcinoma (2 cases) and carcinoid (1 case). No relapse was found in hilar lesions, but 7 relapses and 5 deaths were found in peripheral lesions. Prognostic factors were examined in these cases. Location of lung cancer (hilar or peripheral) was found to be important in early lung cancer. In addition, age was a significant prognostic factor in peripheral early lung cancer with multivariate analysis. No other significant factor was found in our cases. Twelve out of 52 cases with lung cancer had other malignancies after or before operation. These were cancers of second primary lung, colo-rectal, uterus, stomach, breast, thyroid, liver and malignant melanoma. Therefore, we have to carefully observe other parts even after resection of early lung cancer.
