    ABSTRACT: The aim of this study was to investigate the feasibility and the morbidity of sentinel lymph node detection in patients with vulvar carcinoma. In 15 patients with vulvar squamous cell carcinoma, the inguinal sentinel lymph nodes was detected using both peritumoral injection of technetium-99m sulfur colloid and isosuflan blue before the surgical time. The detection of the inguinal sentinel lymph node was never completed by an inguinal lymphadenectomy. In case of metastatic lymph node, patients were treated by complementary inguinal irradiation. A total of 19 inguinal node dissection were performed. The sentinel lymph node was identified in 18/19 (94.7%) groin dissections. A total of 38 sentinel lymph nodes were removed. 4 patients were found to have metastatic lymph node (26.7%) with a total of 6 metastatic lymph nodes. The postoperative morbidity was minimal, with only one patient presenting a permanent edema of the extremity (6.7%) after complementary inguinal irradiation. We confirm the results of previous studies that sentinel node dissection appears to be technically feasible in patients with vulvar carcinoma. This may reduce the morbidity of usual inguinal lymphadenectomy without under-evaluate the nodal status. This procedure could be implemented in future therapy concepts.

    ABSTRACT: Sentinel lymph node biopsy concept was described in several reports since 1994. Technical and identification procedure, false negative risk, learning curve criteria and benefits concerning cancer stadification and postoperative morbidity were assessed. Peroperative and postoperative pathologic examination procedures are improving progressively but remains still under debate. Classification for micro-metastasis, isolated cells and macro-metastasis in sentinel lymph node was suggested but their immunohistochimic detection and prognostic impact are unclear. These parts are discussed in this article.

    ABSTRACT: Benefits provided by sentinel lymph node biopsy (SLNB) include improvement of pathologic examination and lower rate of sequels. The aim of this study was to assess the accuracy of this procedure in large tumors. From march 1999 and december 2003, 663 patients were operated for a breast cancer and underwent a SLNB. All patients with tumor larger than 30 mm and/or with involved SLNB underwent a complete axillary dissection (AD). One hundred and sixteen patients (17.5%) with a tumor larger than 30 mm underwent an AD. Identification rate of SLNB was 94% (109/116). Among the 43 cases with non metastatic SLNB, the AD was negative in 39 cases (90.7%). In four cases a palpable non sentinel lymph node discovered during the SLNB procedure was found to be involved. In one case the lymphoscintigraphy found only one lymph node with a very low fixation and an AD was performed because of low efficiency of the lymphoscintigraphy procedure. SLNB false negative rate was 1.4 % (1/72) among the 72 cases with lymph node involvement. AD was performed in 66 cases (60.5%) during the same operating time than the SLNB. AD showed a lymph node involvement in 30 cases (30/72, 41.7%): in 5 cases among 24 cases with microscopic disease (20.8%) and in 25 cases among 48 cases with macroscopic disease (52%). This series results suggest than AD could be avoided for negative SLNB tumors up to 50 mm at pathologic examination in patients with clinically-measured tumor smaller than 30 mm.

    ABSTRACT: The aim of this study was to define the interest of sentinel lymph node biopsy (SLNB) for the staging of ductal carcinoma in situ (DCIS) and DCIS with micro-invasion (DCISM) in patients with breast carcinoma. From June 1999 to December 2002 we listed, in a retrospective study, 52 patients treated surgically for a DCIS or a DCISM. All except one had an histology before surgery, and all had SLNB. Intraoperative imprint cytology of the sentinel lymph node (SLN) was performed then there were analysed by staining with hematoxylin-eosin. Patients with positive SLN underwent complete axillary dissection. It was removed an average of three SLNs by patient (extreme 1 to 6). Metastases in the SLN were detected in four (7,7%) of the 52 patients, including three cases had only micrometastases in the SLN. In the four patients treated with complete axillary dissection, the SLN were the only positives nodes. The SLNB for DCIS and DCISM increases the involvement rate of lymph node. Because of the widespread for early detection of breast cancer, it is noted a regular increase in the rate of DCIS. Even if the attitude to be had towards the lymph node metastases in these cases is not yet well defined, and so only 2% of the patients approximately die of this pathology, it is interesting because of increase in absolute value of mortality, to try to improve the prognosis criteria to modify the treatment of this pathology.
