Renal Cell Carcinoma Lesions More Likely to be Central in Location

Renal & Urology News is reporting: Researchers at Dalhousie University and Queen Elizabeth II Health Sciences Centre in Halifax, Nova Scotia, analyzed 157 renal masses in patients who underwent treatment for presumed renal cell carcinoma (RCC) based on preoperative imaging.

Of the 157 masses, 141 (89.8%) turned out to be RCC. Fifty (82%) peripheral masses were RCC versus 71 (95.9%) central masses and 20 (91%) hilar masses, Drs. Mason and Rendon reported. Peripheral masses were twice as likely as hilar masses to be benign.

This is practical information that may hep in screening and diagnosis. Perhaps a more central lesion should be more aggressively worked up. It is however, unclear if this translates to all populations and this is a relatively low sample size.
