Conservative surgery and the total thyroidectomy in well-Differentiated thyroid cancer

Despite being the endocrine neoplasia most common thyroid cancer, it occupies only about 2% of all cancers, is more common in women than in men, ratio of 3 to 1 and in most cases patients between 25 and 65 years. Well-differentiated tumors (papillary and follicular) are usually curables.1 The little aggressive biological behavior of well-differentiated tumors, led in the early 80s of last century, there is and Cadi, started talking of factors forecasts in this variety of tumor and introduced different scales for evaluation, assigning patients into two groups: high and low risk. Thus the AGES, AMES, mace, and GAMES DAMES appears. All based their assessment on factors related to the patient (age and sex) and the tumor (size, extent, degree of differentiation, metastasis behavior of DNA, resection), according to the result of this assessment and according to group which is included the patient, less extensive surgical techniques proposed for low risk.1 Age, degree of differentiation, the extent and size of the tumor play an important role in deciding on treatment, which everyone agrees is surgical excision, but opinions vary when determining the extent of resection for effective treatment, hence “to be adjusted surgical techniques according to each patient carcinoma”, this is achieved by the proper staging and defining groups risk.2
