Surgery is the most common treatment for patients with non-small cell lung cancer (NSCLC) in stages I, II and in some patients in stage IIIA. However, for several rea- sons, not every patient in these stages is submitted to surgery. In this study, the authors present the clinical data of the patients diagnosed with NSCLC in surgical stages and analyse the factors that may be related to the survival rate. The retrospective study is based on the systematic revision of 32 consecutive cases diagnosed between Ja- nuary 1998 and December 2001. Every patient has been treated in the oncologic pneumology unit of the pneu- mology service of the Hospital Centre, Vila Real-Peso da Régua The analysed parameters were the following: age, sex, smoking habits, symptoms and performance status. The results of the following exams have also been analysed: Computed tomography, bronchoscopy, transtoracic aspiration biopsy and histological examens (exfoliativa cytology and surgical removed piece). It has also been evaluated the type of treat- ment and the survival rate, calculated using the Kaplan-Meier method. The period of time of this study included 32 individuals, 8 females, 24 males, aged between 31 and 81 years old- avera- ge 64,8 years old. Concerning smoking habits, 40,6% (n=13) were non-smokers, 50% (n=16) were smokers, and 9,4%(n=3) were ex-smokers. Only 16,6% of the NSCLC were in surgical stage: cIA 10 patients, cIB 10 patients, cIIA 0 patients; cIIB 4 patients; cIIIA 8 patients; distribution of the histological types: adenocarcinoma (n=16); squamous cell carcinoma (n=11); mixed pattern (n=1); neuroendocri- ne (n=2) others (n=2). The survival rate after 5 years of the patients submitted to surgery was 75% for pIA; 55% for pIB; 30% for pIIB e 33% for pIIIA. Although the surgery is the only potentially curative therapy for lung cancer, the percentage of patients in surgical state is low and the survival rate after 5 years is above 50% only in stage I (A and B) Key-words: Retrospective study, lung cancer, surgical stages.
