Outcome of patients with lung cancer treated with stereotactic body radiotherapy for bone oligometastases - a European multicenter cohort study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionMetastasis-directed radiotherapy is of increasing importance in the multidisciplinary management of oligometastatic non-small cell lung cancer (NSCLC), but outcome patterns for stereotactic body radiotherapy (SBRT) of bone oligometastases (BoM) remain insufficiently defined. We aimed to determine oncological outcomes and prognostic factors of SBRT for BoM of NSCLC. MATERIALS AND
methodsPatients with NSCLC treated with SBRT for < 5 BoM between 2010 and 2024 at 15 European cancer centers were retrospectively analyzed. Outcomes included freedom from local recurrence (FFLR), progression-free survival (PFS), overall survival (OS), and adverse events.
resultsWith a median follow-up of 14 months (IQR: 7-24 months), 85 patients with 111 treated BoM were analyzed. The 2-year FFLR was 87.2% (95%-CI: 73.3%-94.1%). The 1-/2-year PFS for singular BoM was 60.1% (CI: 44.6%-72.5%)/ 39.9% (CI: 24.6%-54.8%), while for 2-3 BoM they amounted to 10.2% (95%-CI: 0.6%-35.8%) and 0%. In multivariable analysis, less favorable outcome for OS and PFS was associated with larger BoM (HR 1.003; p < 0.01 and HR 1.005, p < 0.001) and increased number of treated BoM (HR 1.72; p = 0.03 and HR 1.93; p < 0.01). Treatment was well tolerated, with fracture rates of 5.4% and no grade 4 and 5 adverse events.
conclusionThis multicenter cohort analysis revealed that SBRT of BoM from NSCLC appears to be an effective and well-tolerated treatment. Presence of singular BoM was a favorable prognostic factor. Prospective studies are needed to confirm these findings and to determine the role of SBRT in the multidisciplinary management of oligometastases.
