| The aim of the work was to analyse the potential influence of different factors on the surgical detection of sentinel lymph node in breast cancer. The procedure has been performed in 704 patients. In 43 out of the 704 cases, the SN was not detected, 24 were palpable and 19 had no palpable tumors. Lymphoscitigraphy was done in 2 h p.i. of 37-55 MBq of 99mTc-nanocolloid. The day before surgery in palpable tumours and 4 h previous to surgery in non-palpable tumours, surgical detection was performed using a gammaprobe. The following factors were analysed: patient age, tumour size, breast quadrant tumour localization, scintigraphic visualizatio,n and the palpation of the tumour. Results: Patient age was significantly (p<0.001) higher in the patients in whom... |

| 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,... |
