1 · What the graph read from it

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.

2 · The registry

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

backgroundSequential inhibition of the vascular endothelial growth factor (VEGF) pathway with sorafenib could be useful for patients with metastatic renal cell carcinoma (RCC). Our aim was to determine the activity and tolerability of sorafenib as a second-line therapy in advanced RCC initially treated with a different VEGF-tyrosine kinase inhibitor (TKI).

methodsA prospective observational cohort in Mexico (2012-2019). We included 132 subjects with metastatic RCC and who had progression despite treatment with sunitinib. The primary end-point was time to disease progression as evaluated every 12-16 weeks.

resultsThe mean age of the cohort was 59 years (interquartile range [IQR] 50-72), 96 (73%) were men, and 48 (36%) had a favorable prognosis according to the IMDC (International Metastatic RCC Database Consortium) prognostic model. The median progression-free survival (PFS) and overall-survival after the introduction of sorafenib treatment was 8.6 months (95% confidence interval [CI]: 6.7-10.5) and 40 months (95% CI: 34.5-45.4) respectively. The median overall survival from RCC diagnosis to death was 71 months (95% CI: 58.2-83.8). On multivariable analyses, age > 65 years was associated with a longer PFS (HR 0.51; 95% CI: 0.31-0.86; p = 0.018). The median PFS in subjects aged > 65 years was longer compared to subjects ≤65 years (14.0 [95% CI: 9.2-18.8] vs. 7.2 months [95% CI: 5.3-9.1]; p = 0.012). Adverse events grade ≥ 3 associated with sorafenib occurred in 38 (29%) patients.

conclusionSequential inhibition of VEGF with sorafenib as a second-line treatment may benefit patients with metastatic RCC, especially in subjects > 65 years old.
