[Analysis of lymph mode recurrence in patients with melanoma and negative sentinel lymph node negative. Retrospective study at the Hospital Saint-Louis, Paris].
Melanoma is a malignant tumor, with dominant lymphatic extension. Sentinel lymph node is the first lymph node touched by melanoma. Our retrospective and monocentric study is about 87 patients, between July 1999 and July 2003. The inclusion criteria were malignant melanoma with Breslow level superior or equal 1.5 mm, and/or Clark level superior or equal IV, and/or ulcerated, and/or in regression. Sentinel lymph node has been negative on histological analysis in 75 patients (86.2%). About these 75 patients, we found five metastatic lymph node recurrence (6.66%) in a short notice (median 10.2 months). For the five patients with recurrence, the original slides and tissue blocks were available for reexamination. Then, we found micrometastasis in two patients (40% of occult metastasis). Our rate of lymph node recurrence in patients with sentinel lymph node negative is about 6.66%. Our analysis make us believe that early recurrence are essentially linked to histological analysis limits, and maybe to skip metastasis existence.
