RCC Rad Onc
Renal Cell Carcinoma Rad Onc
Question | Answer |
---|---|
RCC T1 | Tumor <=7cm in greatest dimension, limited to the kidney |
RCC T1a | Tumor <= 4cm in greatest dimension, limited to the kidney |
RCC T1b | Tumor more than 4cm but <=7cm in greatest dimension, limited to the kidney |
RCC T2 | Tumor >7cm, limited to the kidney |
RCC T3 | Tumor extends into major veins or invades adrenal gland or perirenal and/or renal sinus fat but not beyond Gerota's fascia |
RCC T3a | Tumor invades adrenal gland or perirenal and/or renal sinus fat but not beyond Gerota's fascia |
RCC T3b | Tumor grossly extends into the renal vein or its segmental (muscle-containing) branches, or vena cava below the diaphragm |
RCC T3c | Tumor grossly extends into vena cava above diaphragm or invades the wall of the vena cava |
RCC T4 | Tumor invades beyond Gerota's fascia |
RCC N1 | Mets in a single regional LN |
RCC N2 | Mets in more than one regional LN |
RCC Stage I and 5 yr OS | T1N0M0. 5 yr OS 85-90% |
RCC Stage II and 5 yr OS | T2N0M0. 5 yr OS 65-85% |
RCC Stage III (2) and 5 yr OS | T3N0M0, T1-3N1M0. 5 yr OS 40-60% |
RCC Stage IV (3) and 5 yr OS (2) | T4N0-1M0, AnyTN2M0, Any M1. 5 yr OS 30% if only 1 metastatic site. <10% if >1 metastatic site |
RCC Treatment Recommendations for Radiation | No widely accepted role for adjuvant RT, although retrospective data suggests possible utility in select cases. Unresectable disease could have pre-op RT. Focal palliation of mets can be performed. |
