OPTIMIZING THE STAGING OF MELANOMA PATIENTS FOR THEIR BEST SURGICAL MANAGEMENT
Abstract
Interval nodes (IN) are defined as lymph
nodes that lie along the course of lymphatic
collecting vessels between a primary tumor
site and a draining node field. Sometimes INs
contain metastases and a consensus on their
surgical management is needed. Therefore,
to optimize the surgical management of
melanoma patients with metastatic lymphatic
involvement, especially when the sentinel
lymph node biopsy identifies an unusual
drainage field, we identified patients treated at
the Department of Plastic and Reconstruction
Surgery of Bari between July 1994 and
December 2012 identified with a primarycutaneous
melanoma who underwent
lymphoscintigraphy and subsequent positive-
IN the lymphadenectomy to evaluate the
impact of this procedure on overall survival
and disease-free-period. 51 patients presented
INs, and lymphadenectomy (LA) of the
subsequent lymphatic field was performed in
13 subjects with positive-IN. In 4 cases
additional lymphatic metastases were detected
in the usual basin beyond the IN+.
Recurrence-free period and survival rate at
5 years were higher in patients with positive-
IN who underwent LA than in subjects who
underwent LA due to positive lymph nodes
in the usual field. Immediate lymphadenectomy
of the subsequent lymphatic field in
patients with positive-INs may afford patients
earlier stage treatment of their disease and
improved prognosis.
