AB 91. Prognostic factors in patients with malignant pleural effusion who underwent thoracoscopy diagnostic

Background: The survival of patients with malignant pleural effusion is poor. These patients usually undergo thoracoscopy for the diagnosis and treatment of their condition. Factors affecting the survival of these patients is important to determine to undergo invasive procedures such patients.

Aim of the study: The aim of our study was to evaluate prognostic factors in patients with malignant pleural effusion who underwent thoracoscopy.

Patients and methods: Patients with malignant pleural effusion which was diagnosed by thoracoscopy examined for prognostic factors. The survival time was defined as the time from thoracoscopy to death or last follow-up day. A regression model (regression analysis) was used to determine statistically significant predictors in a bivariate and multivariate analysis.

Results: 90 patients with malignant pleural effusion who underwent thoracoscopy were included in our study. The diagnoses were: lung cancer 43%, breast 23.6%, 12.9% mesothelioma, cancer ourogennetikou 7.1%, gastrointestinal cancers 4.8%, 5.1% other cancers of unknown primary site 3.5%. The mean overall survival was 11 months (1-55 months). When analyzing the results of the histological type of the primary tumor, performance status (performance status) and leukocyte counts were found to be prognostic factors for survival.

Conclusions: The physical condition (performance status), the histologic type of the primary tumor, and the ratio of neutrophils/ leukocytes (N/L ratio) were found to be factors influencing survival of patients undergoing thoracoscopy for malignant pleural effusion. The prospect of detecting patients who meet these criteria will help clinicians to choose their patients about to undergo invasive procedures.
