From the abstract
Solid organ transplant recipients (SOTRs) face frequent advanced cutaneous malignancies, yet data guiding systemic therapy are limited.
Reported results
Among 196 SOTRs treated with ICIs (101 cutaneous squamous cell carcinoma, 83 melanoma, 12 Merkel cell carcinoma), the overall response rate (ORR) was 39.3%, and lack of progression occurred in 58.0%. Graft rejection occurred in 36.9% and graft failure in 22.3%. A higher number of baseline immunosuppressive agents decreased odds of rejection (OR 0.55) and failure (OR 0.38).
Authors' conclusions
ICIs provide antitumor activity but substantial graft-related risk, while T-VEC and HPIs show high response rates with no reported rejection.
