Cancer-Specific Survival Stratification Derived from Tumor Expression of Tissue Inhibitor of Metalloproteinase-2 in Non-Metastatic Renal Cell Carcinoma.

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
Degradation of the extracellular matrix is a prerequisite for the processes of cancer cell invasion and metastasis. The purpose of our study was to assess the association of matrix metalloproteinases (MMP-1, MMP-2, MMP-3, MMP-9) and their inhibitors (TIMP-1 and TIMP-2) with renal cell carcinoma (RCC) progression and cancer-specific survival (CSS), using immunohistochemical analysis of 60 formalin-fixed, paraffin-embedded sections of tumor tissue and normal tissue near the tumor from surgical T1-3bN0 M0 RCC specimens. Significant overexpression of MMP-2 in tumor and normal tissue was correlated with advanced stages, tumor size, sarcomatous differentiation and clinical symptoms. Overall survival was 31.7% (55.2% M0, 9.7% M1) and CSS 56.7% (100% M0, 16.1% M1) with a follow-up of 76 (5-230) months. Fuhrman grade [HR 2.87 (95% CI: 1.28-6.45); p = 0.01], tumor size [HR 1.13 (95% CI: 1.03-1.26); p = 0.009] and low TIMP-2 expression [HR 0.35 (95% CI: 0.16-0.78); p = 0.01] were independent predictive factors of CSS and stratified the patients into three groups with different rates of 10-year CSS; [100%, 73.9% and 20.5% for the good, intermediate and poor prognosis group respectively (p = 0.000006)] . This study offers strong evidence that TIMP-2 expression in tumor tissue may play a crucial role in progression and poor prognosis in human localized and locally advanced RCC.
