Abstract:
Introduction. Colorectal cancer (CR) is one of the most frequent neoplasms in developed countries with a survival index lower than 50% in 5 years. In the whole of Spain more than 11.000 cases per year are diagnosed. In Tarragona province it presents a yearly increase of 3.5% in men and of 2.7% in women.. One of the most important aspects in order to improve survival is to set follow-up programs that attempt to detect the most precociously possible relapses and showing up of pre-neoplasic and neoplasic injuries at a curable stage. Hipothesis. From the set out data, we can establish as a work hipothesis that intensive follow-up of CR operated with curative pretense can contribute to improve survival.Objectives. 1.Study of prevalence, incidence and CR tendency analysis in southern Catalonia districts. 2. Analyse and compare monitoring results on survival of those patients who undergone major CR surgery with a radical purpose, as a result of the fullfilment of a strict follow up program (intensive vs. non intensive).3. Relate patient's progress in terms of the state of progress of neoplasm by the moment the diagnosis is done.4. Investigate which are the predictive factors related to CR prognosis, and that, consequently must be included in follow up programes.Material and Methode. In line with the work's hipothesis, objectives and carried out research, patients were distributed into two groups:-Study of prevalence and incidence.-Study of survival.Which have been the object of different analysis according to the objectives.The first group includes those patients diagnosed of CR during the period of the study (1982 - 2001) and that are living in Tarragona province. The analysis is an observative and descriptive type, so that it allows knowledge of the impact of the disease an
