Combined staging and grading of renal cell carcinoma.
After surgical removal of renal cell cancers we can compare and contrast 3 prognostically differing groups by combining staging after Robson and histologic grading of malignancy. Good cancers (grade 1, stage I or II) have an (uncorrected) 5-year-survival rate of 93%, bad cancers (grade 3, Robson stage II or III) one of 35%. The remaining tumors (intermediate cancers) have a 5-year-survival rate of 64%. Classification in 3 groups is also advisable for future comparison of end result reports.
