    Abstract:
    A total of 1325 patients with bronchogenic carcinoma who were treated at the surgical clinic of the Technical University of Munich between 1981 and 1991 were enrolled in a prospective follow-up study. The 5-year actuarial survival rate of 605 patients with squamous cell carcinoma was 28.2%, of 288 patients with adenocarcinoma 38.0%, of 219 patients with small cell carcinoma 15.4%, of 74 patients with giant cell carcinoma 19.0%, and of 139 patients with other histologic findings 27.8%. In all, 680 patients (51.4%) underwent surgery. Diagnostic thoracotomy without resection was performed in 6.2% of cases. Lethality within 30 days was 1% for lobectomy, 7.3% for bilobectomy, and 7.7% for pneumonectomy including extended resections. The 5-year survival rates among the operated patients were 64.8% for T1N0M0 tumours, 49.4% for T2N0M0, 46.1% for T1N1M0, 43.4% for T2N1M0, 23.8% for T3 and 11.7% for T4. T1N0M0 adenocarcinoma was associated with a better prognosis than squamous cell carcinoma of the same early stage, with a 5-year survival rate of 82.2% vs 55.9%. The prognosis of patients with T3N2 was worse than that of patients with a T3-4 primary tumour but only N0-1 lymph node involvement (5-year survival rate 18.1% vs 31.7%). Stepwise logistic regression analysis identified tumour stage, therapy, and histologic result as the factors with the greatest impact on the prognosis. Adjuvant radiation after resection in patients with T2-3 adenocarcinoma or squamous cell carcinoma improved the prognosis by one tumour stage compared with patients who only underwent surgery. In conclusion, surgical therapy of bronchogenic carcinoma offers favourable survival rates with acceptable risk.(ABSTRACT TRUNCATED AT 250 WORDS)
