Abstract
Objective To evaluate the clinical diagnosis, treatment and prognostic factors of kidney clear cell renal carcinoma(KIRC) in international sample database. Methods From 1998 to 2012, consecutive patients with KIRC who diagnosed and treated in TCGA organizations were enrolled.Clinical characteristics, objective response and survival time were evaluated, and correlation analysis with lncRNA urothelial cancer associated 1 (UCA1) gene was performed. Results 512 patients with KIRC were enrolled.35.4% of patients were female, 59.6% of stage Ⅰ-Ⅱ, 90.0% of white and 45.1% of grade 1-2.Comprehensive treatment was consistent with the clinical guidelines.Significant correlation was found between UCA1 expression and 4 mRNA subtype, 30 genes mRNA expression, mir-101-1 expression and PBRM1 mutation.And patients with UCA1 overexpression could achieve poor prognosis. Conclusion Diagnosis and treatment of the international TCGA-KIRC research meets clinical guidelines.UCA1 overexpression is an important poor prognostic factor.Combined with the clinical relevance of other important driver genes, UCA1 may be significantly valuable for further study.
