Metastasectomy in Renal Cell Carcinoma
• Characteristics associated with improved survival in patients undergoing metastasectomy for first recurrence– Disease-free interval > 1 yr– Single site of metastasis
• Lung better than brain
• 5-yr survival of 44%– Similar 5-yr survival rates with curative resection
upon second and third recurrence

Observation Before Systemic Therapy Safe for a Subset of Pts With mRCC
Phase II study of pts with mRCC and no previous systemic therapy– Observation with periodic CT assessment; initiation of systemic treatment per discretion of physician and
pt
– Unaffected by IMDC risk group (P = .57), location or number of metastases
Median mos of observation until start of systemic therapy: 14.1 mos

Debulking Nephrectomy in mRCC
Pts most likely to benefit from cytoreduction[1] include those with:
– Good performance status with adequate end-organ function
– Potentially surgically resectable primary tumor mass representing at least 75% of total tumor burden
– Good prognostic features– No central nervous system metastases
Current recommendations based on data from trials incorporating IFN alfa-2b[2]

Conclusions
• Risk classification in mRCC is vital for:– Prognostic assessment– Treatment allocation– Expected outcomes– Research
• Although the m RCC MSKCC-risk score may not be the best, it is the most widely used
• We probably should continue to use it as long is the “law of the nation” in clinical research.
