Objective To evaluate the demographic characteristics, clinical course, and outcome in organ transplant recipients with metastatic skin cancer.
Design and Setting An international, multicenter, Internet-coordinated collaborative group retrospectively analyzed data from 68 organ transplant recipients with 73 distinct metastatic skin cancers.
Main Outcome Measurements The Kaplan-Meier method was used to estimate the cumulative incidence of relapse, overall survival, and disease-specific survival after metastatic skin cancer. Univariate Cox proportional hazards models were fit to evaluate factors for an association with survival.
Results Metastasis from skin cancer in organ transplant recipients most commonly consisted of squamous cell carcinoma in regional nodal basins. It was predominantly treated with a combination of surgery and irradiation. By 1 year after metastasis, the cumulative incidence of relapse was 29%, and the 3-year disease-specific survival was 56%. Patients whose initial metastases were distant or systemic had a significantly poorer disease-specific survival than those whose initial metastases were in-transit or regional (risk ratio, 6.5; P<.001).
Conclusions Metastatic skin cancer in organ transplant recipients has a poor prognosis. Preventive, early, and aggressive therapeutic interventions are required to minimize this serious complication of transplant-associated immunosuppression.
