Results: The median tumor size grow from 2.14 (range, 0.30-6.70) cm to 4.33 (range, 1.40-8.80) cm after a median 46.0 months observation period. The average tumor growth rate was 0.80 (range, 0.16-3.80) cm/year.
What percentage of kidney tumors are cancerous?
The odds ratio for the association of malignancy with tumor size was 1.16 (95% CI 1.11–1.22), indicating that each 1 cm increase in tumor size was associated with a 16% increase in the odds of malignancy. The percentage of benign tumors decreased from 37.5% for those less than 1 cm to 7.1% for tumors 7 cm or greater.
