Patients receiving local therapy (surgery or SBRT) or systemic therapy alone (targeted therapy or PD\u20101 inhibitors) were divided into two groups. Progression\u2010free survival (PFS) and overall survival (OS) were analyzed using Kaplan\u2013Meier method, Cox regression model.

Local therapy was surgery in 34 patients (32.1%) and SBRT in 39 (36.8%) patients. Patients treated with systemic therapy alone had more non\u2010clear cell type (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.044), more advanced T stage (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.006), higher number (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.043) but smaller size of lesions (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.042). Patients receiving local therapy had significantly longer PFS than systemic therapy (19.7 vs. 7.5\u00a0months, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.001). After matching, the PFS in the local therapy group remained higher (23.9 vs. 7.5\u00a0months, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.001). The 2\u2010year OS of the local therapy group and systemic therapy group was 91.6% and 71.8%, respectively (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.084). Local therapy was associated with better PFS (HR 0.37; <jats:italic>p<\/jats:italic>\u00a0=\u00a00.0003) and OS (HR 0.23; <jats:italic>p<\/jats:italic>\u00a0=\u00a00.002) in multivariate analysis.
