[Analysis of surgical therapeutic effects in 135 cases of early bronchogenic lung cancer].

135 cases of early bronchogenic carcinoma (T1N0M0) out of 864 operated and pathologically confirmed ones were reported, with an incidence of 15.6%. There were 24 females and 111 males. The ages ranged 23-83 with a mean value of 58.7. There was no operative death. Pathological classification showed squamous cell carcinoma 43.7%, adenocarcinoma 20.0%, bronchiolealveolar carcinoma 25.9%. The postoperative follow-up study covered a period of 1-21 years. The 5-year survival rate was 70.6%, 76.2% and 83.3% respectively. Among this series 42.2% were of central type and 57.8% peripheral type. Their 5-year survival rates were 64.7% and 83.0% respectively, with significant difference (P < 0.01). The clinical features, early diagnosis, and surgical therapeutic effects of early bronchogenic carcinoma and multiple primary lung cancer are discussed.
