Angiogenesis ( neovascularization) plays a key role in carcinogenesis, tumour progression and metastasis. It is now well established that angiogenesis is an essential requirement for the growth and progression of solid tumours. Type of Study: Observational study, longitudinal, comparative, retrospective and prospective of the type of cohorts. Objective: To determine if the increase in the number of angiogenesis in the carcinomas reduces their survival time. Methods: We counted new microvessels (arterioli, capillaries, vens) in three camps of 100 x (without special stain ). The range was 1-200. The followed of patient was evaluated on people-month with range 1-60. Results: A cohortes study was conducted on 85 patients of General Hospital Issste, Tepic, Nayarit, México 1992-1996. We identified Pearson Correlation between tumoral Angiogenesis and time of survival of patients with carcinoma.Ours r Correlation was - 0.55 ( Strong and negative). A big score of neoangiogenesis had less time of survival p < 0.01 . Age, sex, histological differentiation of carcinomas without clinical and statistical differences.2 graphics.
