| Breast cancer is still associated with high mortality rates and one of the most important factors governing long survival is accurate and early diagnosis. In underdeveloped countries, this disease frequently is only detected in advanced stages; however, through mammography, many women have been diagnosed at early stages. In this context, the sentinel lymph node (SLN) technique is associated with less postoperative morbidity compared to axillary lymphadenectomy. Lymphoscintigraphy has emerged as a method for the evaluation of lymphatic drainage chains in various tumours, being both accurate and non invasive. The aim of this work is to present the main aspects which cause controversy about SLN and lymphoscintigraphy and the impact that these procedures have... |

| Biopsy of the sentinel lymphnode (SLNB), the first lymphnode to receive lymphatic drainage from the primary tumor, accurately predicts the axillary lymph node status and, when negative, obviates the need for axillary lymphadenectomy (AL). The aim of this study was, to verify the SLN localization in breast cancer through preoperative lymphoscintigraphy and intraoperative gamma-probe, as well as to demonstrate the benefits of such techniques in preventing complications of AL. Medical records of 228 patients with breast carcinoma, who were underwent SLN localization and, radioguided surgery, from March 2005 to December 2007 were analyzed retrospectively. Data regarding age, tumor characteristic, breast involved, type of surgery, radiopharmaceutical drainage... |

| Sentinel node (SN) status is the most important prognostic factor for localized melanoma. Usually, patients with Breslow thickness of less than 1.0 mm are not included in SN protocols. However, the literature presents a rate ranging from 3 to 7% of nodal recurrence in thin melanoma. Ulceration, regression and high mitotic rate have been considered to be indications for an SN biopsy. The metastatic potential of the vertical growth phase is uncertain. To correlate pathological features in thin melanoma with SN metastasis, we reviewed 358 patients submitted to SN biopsy. Seventy-seven patients with lesions of 1 mm or smaller were included in the study group. Histological evaluation of the primary tumor included thickness, Clark level, mitotic rate,... |
