Abstract

Background: In-transit recurrence is a unique and uncommon pattern of treatment failure in patients with melanoma. Little information exists concerning the incidence, predictors, and natural history of in-transit disease since the introduction of sentinel lymph node biopsy (SLNB). Methods: Between 1991 and 2001, 1395 patients with primary melanoma underwent SLNB. Univariate and multivariate logistic regression analyses were performed to examine the association among known clinicopathologic factors, in-transit recurrence, and distant metastatic failure after the development of in-transit disease. Results: With a median follow-up of 3.9 years, 241 patients (17.3%) experienced disease recurrence, including 91 (6.6%) who developed in-transit recurrence. Independent predictors of in-transit recurrence included age >50 years, a lower extremity location of the primary tumor, Breslow depth, ulceration, and sentinel lymph node (SLN) status. Of the 69 patients who presented with in-transit disease as the sole site of first recurrence, 39 developed distant disease. By univariate analysis, predictors of distant failure among patients with in-transit disease included SLN status, largest metastatic focus in the SLN >2.5 mm2, subcutaneous location of in-transit disease, in-transit tumor size ≥ 2 cm, and a disease-free interval before in-transit recurrence of
