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)
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)
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)
PURPOSE We compared the long-term results of postprostatectomy radiotherapy (RT) from two institutions, one adapting a prospective policy of adjuvant RT and the other salvage RT. METHODS AND MATERIALS Between 1989 and 1997, 69 patients were referred for adjuvant RT to the institution using adjuvant RT and 88 patients with evidence of recurrence were(More)
For giant cell tumors of bone, does radiotherapy provide a safe and effective treatment? This retrospective review includes 24 patients with 26 histologically diagnosed tumors treated with megavoltage radiotherapy between March 1972 and July 1996. Of the 10 recurrent tumors, five had an intralesional resection, two had a biopsy, and three had no biopsy(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)
Twenty pathologic fractures occurred in 285 patients with soft tissue tumors that were treated with radiation therapy and surgery. Twelve of these fractures occurred in 11 patients from a subpopulation of 163 patients with 168 soft tissue tumors of the thigh (155 soft tissue sarcomas and 13 aggressive fibromatosis). The fractures occurred at a mean of 40.5(More)
OBJECTIVE Preoperative treatment of rectal cancer with combined chemotherapy and radiation therapy has become a widely accepted strategy. The current challenge is to improve outcomes whereas minimizing morbidity and maximizing the potential for a sphincter sparing procedure. This study sought to evaluate the safety and efficacy of a combination of 2 novel(More)
