Impact of Antibiotics and Corticosteroids on The Efficacy of Immune Checkpoint Inhibitors in Patients With Advanced Melanoma

Abstract

Objective: The treatment of malignant melanoma has changed a lot in recent years. The use of immune checkpoint inhibitors has prolonged survival in patients with advanced melanoma. Our study evaluates the impact of antibiotics, corticosteroids, and adjuvant treatment on the efficacy of immune checkpoint inhibitors in patients with advanced melanoma.Material and Methods: We conducted a retrospective analysis of metastatic melanoma patients treated with ipilimumab and nivolumab. Concomitant antibiotics, corticosteroids for any reason, and prior adjuvant treatment for melanoma were recorded. Progression free survival and overall survival were compared in each group. Results: We enrolled 29 patients with advanced melanoma treated with immune checkpoint inhibitors. Eighteen 62.1% patients had concomitant antibiotic therapy, and 16 55.2% patients had used corticosteroids for any reason. Seventeen patients 58.6% had adjuvant therapy with interferon alpha.Although not significant, PFS and OS were shorter in patients treated with concomitant antibiotics: PFS 15.9 months vs. 9 months, p=0.561; OS 38 months vs. 18 months, p=0.404.PFS and OS were shorter in patients who had used corticosteroids during immune checkpoint inhibitor treatment: PFS 27.2 months vs. 5.4 months p=0.007 and OS 50 months vs. 14 months p=0.009 . PFS was 23.2 months in the adjuvant interferon group vs. 6.2 months with no prior interferon, p=0.019. Overall survival was also longer in patients with prior adjuvant interferon treatment: 39.8 months vs. 12.9 months p=0.004 .Conclusion: Concomitant use of antibiotics and corticosteroids in patients with advanced melanoma may affect the efficacy of immune checkpoint inhibitors
