The etiology of human breast cancer is unknown; accepted risk factors, e.g., menstrual, reproductive, and family histories, are implicated in less than half of all cases. Various halogenated hydrocarbons--acting as either co-carcinogens or promoting agents--which are derived from the environment and are concentrated in human fatty stores, may also play a(More)
External beam pelvic irradiation in men is frequently complicated by erectile dysfunction. We tested the erectile function in 23 patients (mean age, 65 years) who received radiation therapy for prostate cancer. Fifteen patients experienced changes in erectile potency following radiotherapy. Neurological, endocrine, and vascular testing revealed(More)
PURPOSE The National Surgical Adjuvant Breast and Bowel Project (NSABP) initiated a randomized trial (B-22) to determine if intensifying but maintaining the total dose of cyclophosphamide (Cytoxan, Bristol-Myers Squibb Oncology, Princeton, NJ) in a doxorubicin (Adriamycin, Pharmacia, Kalamazoo, MI)-cyclophosphamide combination (AC), or if intensifying and(More)
This analysis explores the prognostic significance of preoperative carcinoembryonic antigen (CEA) levels in patients with colorectal cancer. The data were derived from 945 patients entered into two randomized prospective clinical trials of the National Surgical Adjuvant Breast and Bowel Project. A strong correlation was evident between preoperative CEA(More)
It has been traditional to exclude patients with radiation-recurrent carcinoma of the uterine cervix or other pelvic neoplasms, incapacitating pelvic pain, postirradiation fistulas, hemorrhage, or malodorous draining tumor necrosis from pelvic exenteration if cure of the malignant disease is not achievable. This negative attitude is a direct result of the(More)
Two hundred fourteen patients with colorectal carcinoma who underwent curative resection for biopsy-proved or autopsy-proved local recurrences with a minimum of 2 years follow-up were evaluated. The only predictive variables for anastomotic recurrence were Dukes' stage and tumor margins. There were 49 Dukes' A lesions with no observed recurrences. There(More)
Radiation enteritis is seen in patients receiving radiation therapy for various pelvic malignancies. Attempts to prevent this have included various surgical as well as nutritional approaches with little success. The use of a polyglycolic acid mesh sling sewn above the pelvic inlet has prevented small bowel descent into the true pelvis in rats and in humans.(More)
The histogenesis of Paget's disease has been hotly debated, and only recently has epidermotropic theory become widely accepted. With the evolution of our understanding of breast cancer, it became apparent that the prognosis of Paget's disease was more a reflection of that of the underlying carcinoma, be it intraductal or infiltrating. The standard treatment(More)
