Abstract:

Objective　To investigate the operative approach and treatment effects of the tumors of pelvic ring.　Methods　From January 1992 to November 2008, 46 patients with tumors in pelvic ring were treated. In all cases, 34 suffered from malignant tumor, and 12 from benign tumor with malignant inclination (27 males and 19 females, aged 32-65 years, averagely 46.8 years). Partial pelvitomy or partial sacrectomy were performed for all cases. The ilioinguinal incision, utilitarian incision, inguinal and perineum incision, and the anterior and posterior approach were used for typeⅠ, Ⅱ, Ⅲ and Ⅳ tumors respectively. The benign and malignant tumors in pubis, ischium or pubic symphysis were resected radically, defects were reconstructed with plastic plate or not.　Results　The following up time was about 3-53 months (averagely 32 months), and 43 patients survived.　Conclusions　Pelvic tumorectomy will get good therapy effects. Radical resection, proper reconstruction according the position of the tumor and carefully protection of the nerve are the key to get good results.
