BACKGROUND The purpose of this study was to determine the clinical course, effects of specific tumor histopathologic characteristics, and extent of surgical treatment on the metastatic rate in patients with rectal carcinoids. METHODS Medical records of 44 patients who presented with rectal carcinoids were retrospectively reviewed. Primary tumors were(More)
BACKGROUND The appropriateness of laparoscopic colon resection (LCR) as treatment for malignancy has been questioned. METHODS From 1992 to 1997, 91 patients were entered into a prospective study of LCR for cancer. Clinical, pathologic, and economic parameters of LCR were compared in a cohort of patients matched for age, tumor stage, and type of colectomy(More)
Renal cell carcinoma is unpredictable in outcome, although the best predictor is tumor stage, followed by histologic grade. The authors retrospectively assessed the clinicopathologic features and DNA ploidy of 103 cases of renal cell carcinoma, the latter determined by flow cytometry of formalin-fixed, paraffin-embedded tissue. The study group comprised 63(More)
BACKGROUND We sought to determine the clinical factors and tumor characteristics associated with the reported poor prognosis in young patients with carcinoma of the colon and rectum. STUDY DESIGN A retrospective review was performed of 186 patients younger than 40 years of age who were treated for primary colorectal adenocarcinoma. The median age was 34.3(More)
In a selected group of 207 breast cancer patients with tumor-free axillary nodes, clinical and pathological features were evaluated as to their relationship to long-term disease-free survival. No clinical feature was found to be prognostically useful. Of pathologic features studied, four appear to have significance. These are (1) the volume of the primary(More)
PURPOSE To determine the clinicopathologic behavior of gastric adenocarcinoma in Hispanics by comparing Hispanic and non-Hispanic patients treated at a single cancer center. PATIENTS AND METHODS Medical records of patients with invasive gastric cancer treated from 1985 to 1999 were reviewed. Diagnoses were pathologically confirmed. Differences in(More)
The effect of perioperative blood transfusion on 5- and 10-year survival following curative resection for intra-abdominal colon carcinoma was investigated retrospectively. Two hundred and seven patients with Dukes' stages A, B, and C carcinoma were divided into two groups: those who received perioperative blood transfusion and those who did not. The data(More)
The clinicopathologic and flow cytometric characteristics of 47 bronchopulmonary carcinoids were assessed, relative to patient survival. Aneuploidy was associated more often with tumor size of greater than or equal to 3.0 cm (P less than 0.004) and lymph node (P less than 0.013) or vascular involvement (P less than 0.004). Also, an aneuploid DNA content was(More)
We conducted an evaluation of the hemostatic integrity of patients with untreated cancer of the prostate. Of 60 patients analyzed retrospectively, only 1 had a mild case of disseminated intravascular coagulation, possibly associated with concomitant estrogen therapy, and in 1 patient mild deep vein thrombosis developed preoperatively, also possibly(More)
This investigation was undertaken to assess the apparent poor survival of older patients with Hodgkin's disease. The clinical course of Hodgkin's disease in 136 patients, 60 to 79 years of age, was compared with that of 223 patients, 40 to 59 years of age. The patients registered from November 1977 through December 1983 had not been previously treated, and(More)
