Abstract
Objective: To present 15 cases of inflammatory myofibroblastic tumor (IMT) in genitor-urinary system, and analyze the characteristics, diagnosis and treatment of the disease. Methods: The diagnostic and therapeutic process of 15 confirmed cases admitted to Sun Yat-sen University Cancer Center between March 2009 and September 2017 were retrospectively analyzed. Of the total cases, 11 cases were diagnosed with cystic IMT with a maximum diameter of 1.0-4.5 cm, 8 cases underwent transurethral resection of bladder tumor(TURBT)and 4 of them underwent partial cystectomy after TURBT and 3 underwent partial cystectomy directly. Two cases were renal IMT with a maximum diameter of 4.0-9.0 cm, one underwent partial nephrectomy and the other accepted radical nephrectomy. One case who was diagnosed with prostatic IMT with a maximum diameter of 3.4 cm underwent transurethral resection of the prostate (TURP) and postoperative radiotherapy. One case who was diagnosed with perineal IMT with a maximum diameter of 2.1 cm underwent tumor resection. Results: The patients were followed up for 10-32 months with a median time of 27 months. No cases relapsed during the follow-up. Conclusion: Surgery is the preferred method for treating IMT in genitor-urinary system. Retrospective study shows a good prognosis in IMT patients, but a long-term follow-up is still required.
