The limits of surgical treatment of non-small cell lung cancer

Between January 1, 1991 until December 31, 1996, 286 patients with non-smalt cell lung cancer were diagnosed and treated in the Department of Tuberculosis and Respiratory Diseases and Palliative Care Unit in Babice nad Svitavou, Czech Republic. There were 251 (87.8 %) males and 35 (12.2 %) females. The mean age of the whole group was 63.8 years. According to TNM staging (regarding the locoregional extension of the disease) as the only criterion 112 patients (39.2 %) were eligible for surgical resection of primary lung tumour. However lung surgery was performed in 57 patients (19.9 %) with successful radical resection in 49 cases (17.1 %) out of 286. Surgical procedure was contraindicated in 55 (49.1 %) out of 112 potentially resectable patients mostly because of limited cardiopulmonary function. The strategy of neoadjuvant treatment before the resection of lung tumour was used for 12 (4.2 %) patients. Chemotherapy, radiotherapy or the combination of both treatment modalities was used in 121 (42.3 %) patients. Symptomatic therapy alone was chosen in 104 (36.4 %) cases. The performance of radical resection of lung tumours resulted in a significant influence on the overall survival in the subgroup of all patients with potentially locoregionally operable disease according to the TNM staging. The median survival period reached 17 months if radical resection was done compared to 8.5 months if radical resection was not performed. This difference is statistically significant, p = 0.05.
