Assessment of Risk Factors Correlated with Satellites and In-Transit Metastases in Primary Cutaneous Melanomas

Background and Objectives: This study aimed to identify the risk factors of primary cutaneous melanomas associated with microsatellites, satellites, and in-transit metastases. Materials and Methods: We performed a retrospective study on patients diagnosed with invasive primary cutaneous melanomas in two pathology departments. The cases were distributed into two groups, comparing the clinical–pathological features of cases that presented microsatellites, satellites, and in-transit metastases with cases that did not present microsatellites, satellites, and in-transit metastases. Results: From the total number of primary invasive cutaneous melanomas diagnosed (n = 204), 22% presented microsatellites, satellites, and in-transit metastases (n = 46). The presence of microsatellites, satellites, and in-transit metastases was strongly correlated with a Breslow index > 4 mm, a Clark level of IV or V, and a pT3 or pT4 pathological stage (p 4 mm, a Clark level of IV or V, and an advanced pathological stage.
