Pulmonary Inflammatory Myofibroblastic Tumor: Surgical Resection and Long-Term Surveillance

Objective: Inflammatory myofibroblastic tumor is a very rare mesenchymal tumor, we share our experience of surgical treatment for inflammatory myofibroblastic tumor. Materials and Methods: From January 2005 to January 2015, 32 patients were recruited in this study including 13 males and 19 females who received surgery and diagnosed as inflammatory myofibroblastic tumor. Postoperative followup was conducted by thoracic surgeons every 3 months until 12 months after surgery, after that every 6 months until 24 months, and then yearly. Results: 32 patients (aged: 9-72 yr, average:37.85 ± 19.42 yr, 13 males and 19 females ) received surgical treatment for inflammatory myofibroblastic tumor (ranged:0.8-8 cm, average:3.84 ± 2.05 cm), including 15 cases of lobectomy, 7 cases of wedge resection, 4 cases of bronchoplasty, 2 case of tracheal tumor resection, 3 cases of sleeve resection and 1 case of wedge resection with biopsy of the chest wall. 31 patients are still alive till now, while one patient die 6 months after the surgery. Conclusion: It suggested that complete resection of the IMT lesions may lead to a promising long-term survival, otherwise it may lead to a compromised outcome.
