Papillary renal cell carcinoma type 1, grade 2: Nucleoli (one annotated by arrows) are conspicuous and eosinophilic at 400 magnification and visible but not prominent at 100 magnification. The WHO/ISUP system is histological tumor grading system for renal cell carcinoma, suggested by the International Society of Urologic Pathologists (ISUP) in ...
Renal cell carcinoma (RCC) is a kidney cancer that originates in the lining of the proximal convoluted tubule, a part of the very small tubes in the kidney that transport primary urine. RCC is the most common type of kidney cancer in adults, responsible for approximately 90–95% of cases. [ 1 ]

Like other cancers, kidney cancer is measured in stages. •Stage 1, the tumour has not spread and is localized. This accounts for 65% of cases of kidney cancer and 92.5% of people with stage 1 kidney cancer survive 5 years. •Stage 2 and 3, the tumour has grown larger and has spread and started to affect regional tissues and lymph nodes.
G (1–4): the grade of the cancer cells (i.e. they are "low grade" if they appear similar to normal cells, and "high grade" if they appear poorly differentiated) S (0–3): elevation of serum tumor markers; R (0–2): the completeness of the operation (resection-boundaries free of cancer cells or not) Pn (0–1): invasion into adjunct nerves
For premalignant dysplastic changes, the CIN (cervical intraepithelial neoplasia) grading system is used. [7] Colon cancer: originally consisted of four stages: A, B, C, and D (the Dukes staging system). More recently, colon cancer staging is indicated either by the original A-D stages or by TNM. [8] Kidney cancer: uses TNM. [9]
This system uses a grading score ranging from 2 to 10. Lower Gleason scores describe well-differentiated less aggressive tumors. Other systems include the Bloom-Richardson grading system for breast cancer and the Fuhrman system for kidney cancer. Invasive-front grading is useful as well in oral squamous cell carcinoma. [4]
