Abstract

The diagnosis of lymphadenopathy after treatment of malignancy is sometimes difficult, especially in patients whose treatment was deemed curative and without local recurrence or those who have increased serum levels of related tumor markers. We aimed to evaluate the effectiveness of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) as a diagnostic tool in patients with lymphadenopathy after curative treatment of malignancy. Consecutive patients with mediastinal, intraabdominal, or pelvic lymphadenopathy after curative treatment of malignancy who were referred to our hospital between October 2003 and September 2007 were enrolled in this study. A total of 62 patients were included. The lymph nodes were located at the mediastinum in 22 patients, intraabdomen in 38 patients, and intrapelvis in 2 patients. From the pathological findings of the FNA sample, 31 patients (50%) were confirmed to have recurrence of the prior malignancy, and 9 patients (15%) were diagnosed as having...
