Background: Satellitosis or in-transit metastasis (S-ITM) has clinical outcomes comparable to node-positivity in cutaneous squamous cell carcinoma (cSCC). There is a need to stratify risk groups.
Objective: To determine which prognostic factors of S-ITM confer an increased risk of relapse and cSCC-specific-death.
Methods: Retrospective multicenter cohort study. Patients with cSCC developing S-ITM were included. Multivariate competing risk analysis evaluated which factors were associated with relapse and specific-death.
Results: Of a total of 111 patients with cSCC and S-ITM, 86 patients were included for analysis. An S-ITM size ≥20 mm, >5 S-ITM lesions and a primary tumor deep invasion were associated with an increased cumulative incidence of relapse [sub-hazard ratio (SHR): 2.89 (95% CI 1.44-5.83, p=0.003), 2.32 (95% CI 1.13-4.77, p=0.021), 2.863 (95% CI 1.25-6.55, p=0.013)] respectively. A number >5 S-ITM lesions was also associated with an increased probability of specific death [SHR: 3.48 (95% CI 1.18-10.2, p=0.023].
Limitations: Retrospective study, heterogeneity of treatments.
Conclusion: The size and the number of S-ITM lesions confer an increased risk of relapse and the number of S-ITM an increased risk of specific-death on patients with cSCC presenting with S-ITM. These results provide new prognostic information and could be considered in staging guidelines.
