Renal cell carcinomas: Correlation of size with tumor grade and extracapsular extension

ABSTRACT

To find the association of tumor size with grade of tumor and its extra capsular extension. A review of record of all renal biopsies performed at pathology department King Edward Medical University over a period of two years was done. It was found that large sized tumors tend to have a higher grade and this correlation was found to be statistically significant [P=0.02]. A significant correlation was also seen between the size of tumor and extra capsular extension [P=0.001]. It was concluded patients presenting with larger renal tumors, who subsequently underwent nephrectomy and histopathological analysis were diagnosed with a higher grade. This relation implies that these patients with larger tumors will in turn have poorer prognosis
