Patient burden of cancer care can be significant, especially for cancers like melanoma where patients are living longer, even with advanced disease. The purpose of this study is to compare the burden of treatment of melanoma patients with in-transit metastases (ITM). There are multiple treatment options for ITM, but no standard due to lack of large cohort comparative studies; thus, the anticipated burden of care may influence therapy choice.Included patients had in-transit melanoma without distant metastasis and were managed at our institution from July 1, 2015 through December 31, 2020 using a combination of surgery, systemic, intralesional, and radiation therapy. We compared treatment burden, (number of treatments, clinic visits, inpatient hospital days, and distance traveled) and response rates using Kruskal-Wallis and chi-squared tests. Recurrence-free survival and estimated charges were exploratory endpoints.There were 42 patients who met the inclusion criteria. As initial treatment, patients had surgery (n = 20), surgery with adjuvant (n = 6), systemic (n = 9), and intralesional therapy (n = 2). Surgery had the lowest treatment burden (median of 1 treatment, 3 clinic visits, and 0 inpatient days) while surgery with adjuvant systemic therapy had the highest burden (median of 13 treatments, 12 clinic visits, and 0 inpatient days). Systemic, intralesional, and radiation therapy were used more often for recurrent ITM. Travel distance (P = 0.88) and response rates did not statistically differ between the four options for first line therapy (P = 0.99). At a median follow-up time of 8.8 mo, 22 (52%) of the cohort required more than 1 therapy to manage recurrent or progressive disease and 14 (33%) progressed to distant disease.Treatment of in-transit melanoma is associated with high burden of care and often requires multiple therapies, even with maximally effective first treatment choice. Factors evaluated in this study may be used to set expectations of treatment course for newly diagnosed patients and may aid in patients' decisions on therapy selection. |
