Predictive role of tissue-based molecular markers in patients treated with sunitinib for metastatic renal cell carcinoma.
Article in World journal of urology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
introductionWe analyzed the clinicopathological data of patients undergoing radical nephrectomy for clear cell type renal cell carcinoma (RCC) who presented with metastasis and were subsequently treated with sunitinib and identified molecular markers in nephrectomy specimens to predict susceptibility to sunitinib. PATIENTS AND
methodsThe medical records of 65 patients who underwent nephrectomy for metastatic clear cell type RCC and were then treated with sunitinib were reviewed. The nephrectomy specimens were subjected to prospective immunohistochemical staining for vascular endothelial growth factor, vascular endothelial growth factor receptor-2 (VEGFR-2), platelet-derived growth factor-B, and platelet-derived growth factor receptor-β expression.
resultsIn 58 evaluable patients, the median value of initial and best overall response was -9.69 and -24.04 %, respectively. VEGFR-2 expression was associated significantly with initial and best overall responses to sunitinib, along with Karnofsky performance status and Memorial Sloan-Kettering Cancer Center prognostic risk group. Multiple linear regression analyses revealed that strong VEGFR-2 expression was positively associated with the best reduction in tumor response (β = -0.275, P = 0.016) and poor Karnofsky performance status was negatively associated it (β = 0.477, P < 0.001). Karnofsky performance status and retroperitoneal lymph node involvement associated independently with progression-free- and overall survivals. None of the molecular markers associated significantly with survival.
conclusionVEGFR-2 expression might be a useful biomarker for predicting the response to sunitinib by patients with metastatic RCC. Karnofsky performance status and retroperitoneal lymph node involvement were predictive of disease progression and death.
