Materials and Methods: A total 222 patients were enrolled retrospectively. Through the study; age, sex, cancer histological type, pleural/pleural effusion FDG uptake in PET/CT, pleural effusion’s location, amount, biochemical property, and pleurodesis efficacy were recorded.
Results: Mean age was 65.52 years, 22.9% of them were women, and 73.3% were men. Lung cancer histological types were; small cell lung cancer (13.1%), adenocarcinoma (72.1%), squamous cell carcinoma (9.5%), and not specified non-small cell lung cancer (5.4%). In 22.1% of the patients, pleurodesis was efficient, in 50% partially efficient, and in 27.9% inefficient. The only independent factor affecting pleurodesis efficacy was found as cancer histological type (p < 0.05). Pleurodesis efficacy was found higher in the squamous cell carcinoma group (p < 0.05).
Conclusions: As far as we know, this is the first study on correlation between efficacy of talc pleurodesis through the pleural catheter and the lung cancer histological types. Pleurodesis was significantly more efficient in patients with squamous cell carcinoma, possibly due to its immunohistochemical behavior.
