[An angiogenesis study of Dukes' B colonic tumors]. / Studio sull'angiogenesi nei tumori colici Dukes' B.

PURPOSE: To evaluate the angiogenesis in Dukes' B colon cancer. PATIENTS AND METHODS: In 60 patients (age, 39-75 years), the microvessel density and the relationship between the angiogenesis and other histologic features were retrospectively evaluated. In an ongoing prospective study, 25 patients have been enrolled to determine the possible therapeutic implications of VEGF quantitative analysis. RESULTS: The retrospective portion of this study confirms the prognostic value of the angiogenesis in terms of recurrences and survival. At present, no conclusions can be drawn from the prospective portion of the study.
