ABSTRACT

Lung cancer in women is increasing in worldwide. This process beginning with the difference on the susceptibility of lung cancer in women smokers may be different from men in the prognosis. In this study, it was aimed to evaluate the clinical features, and prognostic factors of female patients with lung cancer diagnosed between January 2000-December 2005. The data of 109 patients data was evaluated. The mean age was 59.40 +/- 11.56 and 17 (15.6%) patients were smokers. In 20 patients (18.3%) having a family history of cancer, 55% of them had a relative with lung cancer. In admission, cough (81.7%), dyspnea (78.9%), chest pain (40.3%) were the most frequent presenting symptoms. The most common site of tumoral lesion in bronchoscopy were right upper lobe (16.5%). In the study group histopathological diagnosis were as follows; adenocarcinoma (44.9%), small cell lung cancer (SCLC) (19.3%), squamous cell (10.1%), non-small cell lung cancer (NSCLC) --undefined (22.0%), carsinoid tumors (2.8%), in non-smokers adenocarcinoma was significantly higher than smokers (44.9%/17.7%) (p< 0.001). 61.9% of NSCLC patients and 57.1% of SCLC patients had a stage IV disease at the initial evaluation. The most common sites of metastasis were bone (28.4%), liver (22.9%), and brain (11.9%), there were multiple metastasis in 10 patients. Median survival time was found as 288 days. In univariate analysis, comorbidity, primary tumor stage, bone metastasis, advanced disease stage, ECOG performance score >or= 2 and supportive care alone were poor prognostic factors. In multivariate analysis, poor performance status (p= 0.003), advanced disease stage (p= 0.002) and bone metastasis (p= 0.04) were negatively related to survival. In women, the definition of the clinical features, disease course and survival related factors may contribute to our future treatment approaches based on our national data.
