Combined ultrasound-guided cuttingneedle biopsy and standard pleural biopsy for diagnosis of malignant pleural effusions

The most efficient approach to diagnose malignant pleural effusions (MPEs) is still controversial and uncertain. This study aimed to evaluate the utility of a combined approach using ultrasound (US)-guided cutting-needle biopsy (CNB) and standard pleural biopsy (SPB) for diagnosing MPE.
