    Malignant pleural effusion is a common complication of advanced malignancy. It affects 15% of oncology patients, and lung cancer and breast cancer are the most common causes.1 Identifying of the condition is essential because its presence has implications in the staging, management and prognosis of a patient with established malignancy, and it can serve as the source of initial diagnostic material. However, the diagnosis can be made only after the detection of neoplastic cells or tissue in the pleural space. Although cytology or biopsy is the confirmatory study, their positivity rate is low. Therefore, malignant pleural effusion can remain undiagnosed even after the analysis of a single or even multiple cytological or biopsy specimens.

    Demographic information (age, sex, symptom, smoking history) and several laboratory markers as well as imaging studies are used in the diagnosis of malignant or benign pleural effusion in clinical setting. A previous study demonstrated that artificial intelligence (AI) framework based on routinely collected clinical data could significantly improve diagnostic performance in distinguishing malignant from benign pleural effusion.2 They revealed the improved …
