Evolution of Metabolic and Immune Dysfunction in In-transit Melanoma

Summary

Melanoma in-transit metastases (ITMs) continue to represent a therapeutic dilemma, in that no standard method of treatment has been uniformly adopted. The complexity and heterogeneity of patient and disease characteristics, including the location and number of ITMs presents a barrier to a one size fits all treatment approach. Treatment of patients with limited regional disease remains challenging. Patients are typically treated with a combination of surgery, regional therapy, systemic therapy. Data on the management of ITMs is limited, even with the availability of immunotherapy (IMT). This study will use the unique etiology of ITMs to facilitate the understanding of how individual lesions metabolically and immunologically evolve as they move away from the primary tumor site. It is hypothesize that as ITMs move away from the primary melanoma site each will harbor progressively hypermetabolic tumor cells and a harsher microenvironment.
