INTRODUCTION: Systemic therapy of patients with metastatic renal cell carcinoma (mRCC) has improved in the past years, with the advent of new immunotherapy-based combinations as a standard treatment option for first-line therapy. Nevertheless, particularly in good-risk patients by IMDC criteria, tyrosine-kinase inhibitors (TKI) may remain as an option for some patients. We reviewed our experience with TKI as first-line therapy for mRCC patients, trying to identify subgroups of patients that may still benefit from this strategy. MATERIAL AND METHODS: All patients with mRCC treated with first-line TKI, and adequate follow-up, in University Hospital La Paz (Madrid, Spain) between 2007 and 2020 were analyzed. Patients treated inside a clinical trial were excluded from this analysis. RESULTS: A total of 90 patients treated with first-line TKI were included. Regarding IMDC criteria, 33 patients (36.7%) were good-risk, 41 patients (45.5%) intermediate-risk, and 16 patients (17.8%) poor-risk. With a median follow-up of 49 months, the median overall survival (OS) for good, intermediate, and poor-risk patients was 54, 24, and 16 months (p = 0.004). When intermediate-risk was divided into patients with 1 or 2 risk factors, differences in OS were also statistically significant: patients with 1 risk factor had a median OS of 33 months, while patients with 2 risk factors had a median OS of 16 months, the same as poor-risk patients (p = 0.003). In the multivariate analysis, trying to find out which of the IMDC factors had a more remarkable weight in the prognosis of the patients, both ECOG and hemoglobin levels by themselves were significantly associated with OS. CONCLUSION: In our group of patients, survival outcomes were different among patients with intermediate-risk with 1 or 2 risk factors by IMDC criteria. These could help select patients that may benefit from first-line treatment with a TKI, particularly in settings with difficult access to novel therapies, such as immunotherapy-based combinations.
