Sunitinib Rechallenge After Other Targeted Therapies in Metastatic Renal Cell Carcinoma Patients: A Single-Center, Retrospective 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
backgroundSunitinib is still one of the standard therapies in metastatic renal cell carcinoma (mRCC). Despite the benefit of sunitinib resistance will develop in the majority of patients. Most of them receive multiple sequential therapies during the course of disease.
objectivesTo retrospectively investigate the efficacy and safety of rechallenged sunitinib in third or later line settings. PATIENTS AND
methodsTwenty-one mRCC patients were identified who received rechallenged sunitinib between March 2010 and April 2018. Patients received sunitinib in first or second line, then other tyrosine kinase and/or mTOR inhibitors were applied, then sunitinib was rechallenged. Patients' characteristics, tolerability, treatment modalities, and treatment outcomes were recorded. The primary end-point was progression-free survival (PFS) of rechallenged sunitinib.
resultsMedian age of patients was 62 years at the start of sunitinib rechallenge. Sixty-seven percent of patients were male. All patients had prior nephrectomy. Upon rechallenge 4 patients achieved partial response and 12 stable disease. The median PFS of first sunitinib treatment was 22 (95% CI 17-26) months and for rechallenged sunitinib 14 (95% CI 6-20) months. No increased severity of prior toxicity or new adverse events was reported during rechallenged sunitinib. The median overall survival (OS) from the start of first sunitinib was 67 (95% CI 46-76) months. Multivariate Cox regression analysis revealed that younger age (< 57 years) at start of first sunitinib (HR = 0.24; 95% CI 0.07-0.79; p = 0.019) and longer (> 2 years) first sunitinib treatment (HR = 0.28; 95% CI 0.09-0.93; p = 0.038) were independent markers of longer OS.
conclusionSunitinib rechallenge is a feasible and tolerable option with clinical benefit in selected mRCC patients.
