[Histological structure and tumor size as prognostic factors in the surgical treatment of patients with peripheral lung cancer].

An analysis of long-term (5 years) results of treatment of 444 patients with peripheral lung cancer has shown that in adenocarcinoma the tumor size is of no significance for prognosis of the disease while in squamous cell carcinoma of more than 5 cm diameter the prognosis is significantly worse (almost 2 times). Since the squamous cell carcinoma is known to be the less biologically active form of lung carcinomas the authors consider that the main task is the organization of measures for early detection of this kind of tumors less than 5 cm in diameter.
