OBJECTIVES: Pelvic reconstruction after tumor resection is challenging. METHODS: A retrospective study had been performed to compare the outcomes between patients undergoing reconstructive surgery of the pelvis with allogeneic bone graft after en bloc resection of pelvic tumors and patients undergoing en bloc resection only. RESULTS: Patients without reconstruction had significantly lower functional scores at 3 months (10 vs. 15, P = 0.001) and 6 months after surgery (18.5 vs. 22, P = 0.0024), a shorter duration of hospitalization (16 days vs. 40 days, P < 0.001), and lower hospital costs (97,500 vs. 193,000 RMB, P < 0.001) than those undergoing pelvic reconstruction. Functional scores were similar after 12 months of surgery (21.5 vs. 23, P = 0.365) with no difference in the rate of complications between the two groups (P > 0.05). CONCLUSIONS: Pelvic reconstruction with allogeneic bone graft after surgical management of pelvic tumors is associated with satisfactory surgical and functional outcomes. Further clinical studies are required to explore how to select the best reconstruction method. Level of evidence iv, case series.
