Association of immune checkpoint inhibitor and tyrosine kinase inhibitor-related cutaneous adverse events with outcomes in metastatic renal cell carcinoma. PG - 1242-1247 LID - 10.1111/ijd.15583 [doi] AB - INTRODUCTION: Skin toxicity is a common, expected side effect of tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibitors (ICIs) used for metastatic renal cell carcinoma (mRCC). We evaluated the association between skin toxicity and clinical efficacy outcomes of these agents in mRCC patients. METHODS AND MATERIALS: Data were obtained from patients with mRCC treated with TKIs and/or ICIs from 2016-2019 at a referral hospital in Mexico City. Clinical outcomes were compared among patients who developed treatment-related cutaneous adverse events (AEs) and those without skin toxicity. RESULTS: Thirty-five patients with mRCC were identified who were treated with sunitinib (51.4%), nivolumab plus cabozantinib (28.6%), nivolumab monotherapy (17.1%), or ipilimumab plus nivolumab plus cabozantinib (2.9%). Any grade skin toxicity was seen in 65.7% of patients. With a median follow-up of 14 months, radiological responses were as follows: 48.6% stable disease, 25.7% partial response, and 2.8% complete response. Compared to subjects without skin toxicity, patients who developed cutaneous AEs had higher disease control rate 91.3% vs. 50.0% (P = 0.019) and superior 12-month overall survival rate 91% vs. 67% (P = 0.01), respectively. There was a trend toward improved median progression-free survival (16 months vs. 5 months, P = 0.13). Grade 1-2 cutaneous toxicity was found to be predictive for disease control, with HR 2.72 (95% CI 1.1-6.71, P = 0.030), and all grade cutaneous toxicity was prognostic of overall survival, with HR 0.18 (95% CI 0.04-0.91, P = 0.039). CONCLUSION: Cutaneous AEs are associated with improved overall survival and response in patients with mRCC treated with immunotherapy and/or TKIs.
