Background/Aim: Numerous new treatment options have been approved for metastatic renal cell carcinoma (mRCC) in the last decade. Nevertheless, not all patients receive systemic therapy. Certain patients present with very advanced disease, poor Eastern Cooperative Oncology Group performance status (ECOG PS), or severe comorbidity, i.e. factors that lead oncologists to prefer best supportive care (BSC) instead of systemic therapy. The aim of this quality-of-care study was to identify baseline factors (disparities) associated with receipt of systemic therapy rather than BSC. Patients and Methods: This retrospective analysis included 140 consecutive patients managed in a rural region of Norway (2007-2022). Two differently managed groups were compared in univariate tests followed by multi-nominal regression. Results: The majority of patients (n=95, 68%) had received systemic therapy. Typical patients were males in their 60s or 70s, with clear cell histology, prior nephrectomy, and intermediate prognostic features. Patients who received systemic therapy lived significantly longer than those who did not (median 30.4 versus 5.0 months, p<0.001). Survival benefit of systemic treatment was observed even in patients with ECOG PS3 or age =80 years. In addition to younger age (p<0.001) and better ECOG PS (p<0.001), metachronous presentation was associated with higher rates of systemic therapy utilization (p=0.03). Conclusion: Assignment to systemic therapy for mRCC was individualized in the present patient population. In all age and ECOG PS subgroups, systemic therapy was associated with better survival (doubling at least). Optimum utilization rates are difficult to determine. However, in light of the survival outcomes, a rate of 12% in patients aged 80 years or older appears rather low. [ABSTRACT FROM AUTHOR]
