The optimal treatment of giant cell tumors of the pelvis and sacrum is controversial. Our current patient series was combined with cases identified in a review of the literature published in the past 50 years, yielding a combined group of 239 lesions for study. Recurrence rates were 49% for patients who had radiation therapy alone, 47% for patients who had(More)
OBJECTIVES The purpose of this article is to discuss the natural history, treatment, and outcomes for patients with aneurysmal bone cysts (ABC). METHODS Review of the pertinent literature. RESULTS ABCs account for 1% to 2% of all primary bone tumors, usually present in the first 2 decades of life, and exhibit a slight female preponderance. The majority(More)
PURPOSE An aneurysmal bone cyst (ABC) is a rapidly expansile and destructive benign tumor of bone that is usually treated by curettage and bone graft, with or without adjuvant treatment. For recurrent tumors, or tumors for which surgery would result in significant functional morbidity, does radiotherapy (RT) provide a safe and effective alternative for(More)
BACKGROUND Our institution has previously demonstrated a survival advantage conferred by preoperative neoadjuvant therapy for locally advanced rectal cancers. We now report our results using transanal excision as definitive surgical therapy in a selected group of patients who experienced significant downstaging of T3 rectal cancers after neoadjuvant(More)
The objective of the current study was to define the optimal treatment for patients with retroperitoneal soft tissue sarcomas (RPS). The authors conducted a review of the pertinent literature and found that the majority of patients had locally advanced RPS at the time of diagnosis. Surgery was the mainstay of treatment, and macroscopic total excision was(More)
Various vasoactive agents have been used to modify tumor blood flow with the ultimate goal of improving cancer detection and treatment, with widely disparate results. Furthermore, the lack of mechanistic interpretations has hindered understanding of how these agents affect the different physiological parameters involved in perfusion. Thus, there is a need(More)
PURPOSE To assess the safety, tolerance, and efficacy of transurethral surgery plus concomitant cisplatin, 5-fluorouracil (5-FU), and radiation therapy in conjunction with selective bladder preservation in patients with muscle-invading bladder cancer. Patients and Methods. Thirty-four eligible patients with clinical stage T2-T4a, Nx M0 bladder cancer(More)
Soft tissue sarcomas are a relatively rare, heterogeneous group of tumors arising from mesenchymal tissues and occurring almost anywhere in the body. The rate of progression and likelihood of hematogenous dissemination, usually to the lung, is determined primarily by tumor grade. The likelihood of regional spread is low. Pretreatment evaluation includes(More)
The purpose of this article is to review the pertinent literature and to define the optimal treatment of patients with aggressive fibromatosis. Data indicate the likelihood of local recurrence after surgery is high, particularly if margins are positive. Moderate-dose radiotherapy alone for gross disease or after a microscopically incomplete resection yields(More)
OBJECTIVE To discuss the treatment and outcomes for giant cell tumor (GCT) of bone. MATERIALS AND METHODS Review of the pertinent literature. RESULTS GCT is a rare benign bone lesion most often found in the extremities of women in the third and fourth decades of life. Surgery is the mainstay of treatment and usually consists of intralesional curettage;(More)
