Background:
The current available evidence on the management of metastatic renal cell cancer (mRCC) in real life is scarce in our environment. We present a summary of the existing real-world data and the results of an analysis describing the clinical characteristics, treatments, and health outcomes of patients with mRCC in northern Spain.
Methods:
Retrospective observational study. Adult patients diagnosed with mRCC between Jan 2007 and Dec 2019 were included. Epidemiological, efficacy and toxicity data were collected. Median overall survival (OS) and progression-free survival (PFS) were determined using the Kaplan-Meier method.
Results:
A total of 829 patients were included (median age at diagnosis:63 years;73% men). Median follow-up was 180 months. The preponderant histology was clear cell (85%). In 50% the initial diagnosis was advanced disease. The distribution according to IMDC prognosis was good (24%), intermediate (50%) and poor (26%). The most frequent metastatic locations were lung (68.3%) and lymph node (41.0%). Most patients (95%) received a first line (1L) systemic treatment, 60% were treated with a second line (2L) of therapy and 37% received third line (3L). A VEGFR-TKIs was the most common treatment (1L: 90%, n = 507; 2L: 49%, n = 233; 3L: 54%, n = 156) followed by mTOR inhibitors (1L: 2%, n = 4; 2L: 27%, n = 126; 3L: 23%, n = 68) and immunotherapy (1L: 3.7%, n = 25; 2L: 27%, n = 126). Median OS was 24.5 months in the general population. According to IMDC prognostic groups, OS was 52.5, 25.7 and 9 months respectively. From the start of the 1L, 2L, and 3L treatment, median PFS was: 1L: 7.8 (6.8-9.0); 2L: 4.9 (4.3-5.5); 3L: 4.3 (3.8-4.8) months. No unexpected toxicity was reported.
Conclusions:
The Real-World Data on the management of mRCC in Northern Spain are comparable in epidemiology, efficacy, and safety to studies conducted in other areas of the world. The significant reduction in the number of patients receiving second and subsequent lines of therapy hampers the access to new therapies developed in this context.
