Synchronous brain metastases as a poor prognosis factor in clear cell renal carcinoma: a strong argument for systematic brain screening.
Article in Journal of neuro-oncology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposeBrain metastases (BM) usually represent a poor prognostic factor in solid tumors. About 10% of patients with renal cancer (RCC) will present BM. Local therapies such as stereotactic radiotherapy (SRT), whole brain radiotherapy (WBRT), and surgery are used to achieve brain control. We compared survival between patients with synchronous BM (SynBM group) and metachronous BM (MetaBM group).
methodsIt is a retrospective study of patients with clear cell renal cell carcinoma (ccRCC) and BM treated with TKI between 2005 and 2019 at the Centre Léon Bérard in Lyon. We collected prognostic factors: The International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) risk score, the TNM stage, the histological subtypes and the Fuhrman grade. Overall survival (OS) was defined from diagnosis of metastatic ccRCC to death. Brain progression-free survival (B-PFS) was defined from focal brain therapy to brain progression or death.
results99 patients were analyzed, 44 in the SynBM group and 55 in the MetaBM group. OS in the MetaBM group was 49.4 months versus 19.6 months in the SynBM group, p = 0.0002. The median time from diagnosis of metastasic disease to apparition of BM in the MetaBM group was 22.9 months (4.3; 125.7). SRT was used for 101 lesions (66.4%), WBRT for 25 patients (16.4%), surgery for 21 lesions (13.8%), surgery followed by radiation for 5 lesions (3.3%). B-PFS for all patients was 7 months (IC95% [5.0-10.5]).
conclusionsSurvival of patients with synchronous BM is inferior to that of patients with metachronous BM. Outcome is poor in both cases after diagnosis of BM. Brain screening should be encouraged at time of diagnosis of metastatis in ccRCC.
