| Summary: | ABSTRACT Background Inflammatory myofibroblastic tumor (IMT) is a rare intermediate‐grade neoplasm. It presents a great challenge in diagnosis and treatment. This study aims to identify the clinicopathological characteristics of IMT. Methods A retrospective study was conducted, enrolling patients with IMT at Peking Union Medical College Hospital from January 2013 to October 2023. Clinical information, treatments, and efficacy were analyzed. Results A total of 72 patients were enrolled, including 38 men and 34 women, with a median age of 46.5 years. The most common primary site included the lung (n = 15, 20.8%), intestinal tract (n = 8, 11.1%), abdominal cavity (n = 7, 9.7%), and nasal sinus (n = 5, 6.9%). Thirty patients harbored anaplastic lymphoma kinase (ALK) fusion genes; Sixty‐five (90.3%) patients underwent surgical resection, and 11 of them had postoperative recurrence. Thirty patients received systemic therapy, including nonsteroidal anti‐inflammatory drugs (n = 1), steroids (n = 5), chemotherapy (n = 7), targeted therapy (n = 2), and immune checkpoint inhibitor (n = 1). Conclusions The most common site of IMT is the lung. Surgery is the main treatment for IMT, and postoperative adjuvant therapy for ALK‐positive patients needs to be focused. The molecular testing is essential for all patients diagnosed with IMTs. Systemic treatment needs further research. |
