Reconstruction with Modular Hemipelvic Endoprosthesis after Pelvic Tumor Resection: A Report of 50 Consecutive Cases

Abstract

PurposeTo evaluate the effectiveness of reconstruction with a modular hemipelvic endoprosthesis after pelvic tumor resection.MethodsWe retrospectively studied 50 consecutive patients diagnosed with pelvic tumor from 2003 to 2013. All patients received limb-salvage surgery and reconstruction with modular hemipelvic endoprosthesis.ResultsPatients were followed for an average of 54 months. At the most recent follow-up, 32 patients were alive with an estimated three-year and five-year survival rate of 66.3% and 57.5% according to the Kaplan-Meier survival analysis. Eighteen patients died from the tumor, with a mean survival of 28 months, and 9 patients experienced local recurrence at an average of 19.6 months after surgery. Patients with marginal or intracapsular surgical margins had a significantly higher recurrence rate than those with wide margins (p=0.02). Metastasis occurred in 12 cases at an average of 16 months after surgery. The perioperative complication rate was 48.0%, and the most common complications were wound healing disturbance (28.0%) and deep infection (14.0%). The endoprosthetic complication rate was 16.0%, and breakage of the pubic connection plate was the most common complication. The mean Musculoskeletal Tumor Society score was 61.4%.ConclusionReconstruction with a modular hemipelvic endoprosthesis after pelvic tumor resection can improve function, with an acceptable complication rate.

“…Accordingly, there is much controversy about optimal surgical treatment, systemic chemotherapy, and radiotherapy. In congruence with previous studies, we found that surgery confers a significant advantage in OS and CSS of patients with pelvic CS . Of the types of surgery involved, wide surgical resection was a significant prognostic factor for the long‐term survival and local recurrence of decrease, and individual reconstruction was a key to maintaining good function .…”

“…A second-generation cephalosporin (cefuroxime) was provided intravenously at the time of surgery and continued orally for 2 weeks, similarly to a protocol used in man. 19 The nature of the tumor was not determined in the case reported here because fine needle aspiration (FNA) of deep lesions can seed tumor cells along the tract created by the needle. 20,21 Some authors therefore suggest avoiding FNA or biopsy of a lesion if it is surgically resectable, 20 and biopsy should be performed only if it is likely to change the treatment option or alter an owner's willingness to consent to treatment.…”
