Long term survival after compound hemipelvectomy

Three patients survived free of disease ten and one-half, ten and almost six years, respectively, following compound hemipelvectomy for a variety of tumors. Each patient had been operated upon previously at least three times, but the tumors were still well localized despite the propensity for local infiltration or growth. In addition to the lower extremity and the ipsilateral pelvic bones, varieties of organs were resected. In one patient with chondrosarcoma of the pelvis, there was a local recurrent mass and, in another with adenocarcinoma of the appendix, a solitary pulmonary metastasis. Both of these lesions were successfully resected, and the patients remained free of disease nine and four and one-half years, respectively, after resection of the recurrent lesions. The third patients had carcinoma of the penis with metastases in both groins; carcinoma of the breast devedeveloped nine and one-half years after hemipelvectomy. The two younger patients were fitted with prostheses, and all three adjusted fairly well physically and psychologically to their disability. Frequently, the huge size of these tumors, the infiltration of many contiguous structures and, possibly, other features known to be associated with a bad prognosis make them appear to be incurable. We suggest that slowly growing tumor which remain localized for a long time can be controlled if adequately excised, possibly because they may be associated with strong systemic immunity. The extremely few such patients who may be encountered in surgical practice ought, therefore, to be recognized as potentially curable and treated accordingly, despite the often formidable risk or technical problems at operation and the resultant postoperative disabilities.
