      Introduction

      Immunotherapy is nowadays one of the most used treatments in oncology, although it is not free of adverse effects. In this study, we intended to analyse therapeutic response and immune-related adverse effects (irAEs) of immunotherapy in a sample of patients with non-small cell lung carcinoma (NSCLC) treated with pembrolizumab or nivolumab.

      Methods

      In this retrospective study, clinical data from patients with diagnose of metastasized NSCLC, treated with pembrolizumab or nivolumab, were collected between June 2015 and January 2020 at the Pulmonology Department of Centro Hospitalar e Universitário São João, Porto, Portugal.

      Results

      In a sample of 147 patients, 38 patients (25,9%) developed irAEs, the majority being grade 1 or 2 (n=30, 20,4%). The commonest events were colitis (n=9, 6,1%), skin rash (n=7, 4,8%) and hyperthyroidism (n=6, 4,1%).

      PFS and OS were statistically higher in the group with irAEs compared to the group of patients without irAEs among patients treated in 1st line (PFS: 18,2 months (CI(95%):5,0-31,5) vs. 4,8 months (CI(95%):2,6-6,9); OS: 20,2 months (CI(95%):7,5-34,5) vs. 6,0 months (CI(95%):3,4-9,0)) and in 2nd line or higher (PFS: 14,1 months (CI(95%):10,1-18,4) vs. 5,9 months (CI(95%):4,3-7,6); OS: 18,3 months (CI(95%):14,1-22,4) vs. 8,6 months (CI(95%):6,8-10,6)), p<0,05.

      Conclusion

      In this sample of patients with NSCLC treated with PD-1 blockers, results suggest an association between the occurrence of irAEs and a better therapeutic response.
