Cancer is one of most worry public health problem in many parts of the world and breast cancer is the most common in the women in the Western World. Tamoxifen has been the mainstay of adjuvant endocrine treatment for many years and it is the drug more prescribed in the treatment of breast cancer, mainly in the adjuvant modality, in pre or post menopaused patients, positive estrogen and/or progesterone receptors, used too in the treatment of locally advanced and metastatic disease and in smaller proportion in patients with formal contraindication of surgery or that refuse to submit this treatment modality. In the neoadjuvancy it is just used in clinical research. The tamoxifen also reduces, in the adjuvant modality, used during five years, the probability of recurrence in 47% and deaths caused by breast cancer in 26% and the two main side effects, in spite of rare, are the increase of the prevalence of endometrial cancer and of thromboembolic phenomenon. This study had as main objective to evaluate the patients, breast cancer bearers, in the Institute of Cancer of Ceará, treated with tamoxifen, in the adjuvant form, in the period of 1994 to 2004 regarding the main benefits and side effects. It had been performed the analysis in agreement with the hormonal receptors, clinical and pathological staging and compared with the historical data, as well as the tamoxifen protector effect against new contralateral breast cancer occurrence, main local relapse and distant metastasis in accordance with clinical and pathological staging, and at last, the quality of prontuary information and medical registers. Two hundred seventy nine patients’ prontuaries were analyzed in respect to the demographic data’s, age, menopausal status, clinical and pathological staging, estrogen and/or progesterone receptors status, cases of endometrial cancer, modality of treatment, death causes, histological type and axillary lymph nodes status. It had been evaluated that most of the data is in agreement with the literature, in other words, the early breast cancer group as Clinical Stage I, treated with tamoxifen, had clinical benefice, when compared with the group with locally advanced disease, as well as, less metastasis and locally relapse, benefices to patients with positive estrogen receptors . The damage of the analysis was resulting from the quality accomplished found in the prontuaries, so, doctors should be more and more stimulated to document, in a clear and readable way, the largest number of possible information, not just the positive ones, but all those that more frequently can have relationships with the use of any prescribed medicine or procedure, and the importance to confirm the status of hormonal receptor.
