[Surgical treatment of bronchogenic carcinoma. Long-term results in 496 surgical patients].
BACKGROUND
The operability of lung cancer and the period of survival after resection of the lungs in our country does not yet attain the standard recorded in some advanced countries. The objective of the present work is to analyze factors which influence the survival period after resection therapy of lung cancer.


RESULTS
In 1985-90 in our department 496 patients were operated on account of lung cancer. This number comprised 31 patients subjected to explorative thoracototomy and three patients with pulmonary resection on account of a stage IIIb (pTNM) tumour who were excluded from the statistical analysis. The retrospective study proper analyzes the results of 462 patients (403 men and 59 women) operated in stages I, II and IIIa. Their mean age was 57 years (range 30-74 years, SD 7.5 years). The most frequent histological type was epidermoid carcinoma (68.8%), adenocarcinoma 18.2%, small-cell tumours 5.4% (25 patients). In 262 patients operated on account of lung cancer in stage I (pTNM) the probability of five-year survival was 49.2%, in patients in stage II 42.1%, in 158 patients in stage IIIa 20.9% (for all histological types combined). In 437 patients after resection of the lungs on account of non-small-cellular carcinoma the probability of five-year survival was as follows: stage I 50.0%, stage II 45.0%, stage IIIa 21.2%.


CONCLUSIONS
The probability of five-year survival for the whole group of 462 patients in stages I, II and IIIa was 38.8%. The most important factor which influenced the probability of five-year survival was the stage of the disease. Neither age nor sex of the patients nor the histological type of the tumour had a statistically significant effect on the probability of five-year survival.
