Decision Point: Patient Management
How would you manage the patient?
Tumour biopsy and systemic targeted therapy
Cytoreductive nephrectomy and observation
Cytoreductive nephrectomy followed by systemic targeted therapy
Systemic targeted therapy (neoadjuvant) followed by cytoreductive nephrectomy
Enrollment in clinical trial
Cytoreductive Nephrectomy
How Does It Work? Proposed Mechanisms
• Decreased tumour bulk?
• Azotemia and acidosis?
• Decreased immunosuppression? o Bulky tumours may produce products that inhibit
immune system
• Decreased angiogenesis?
Cytoreductive Nephrectomy and Interferon
Flanigan RC, Mickish G, Sylvester R, Tangen C, Van Poppel H, Crawford ED. Cytoreductive nephrectomy in patients with metastatic renal cell cancer: A combined analysis. J Urol. 2004 Mar; 171: 1071-1076.
Cytoreductive Nephrectomy
Change of Preferred Systemic Therapies
• Molecular targeted therapy
o more effective
o better responses in primary tumour
• Trials have yet to report regarding
effectiveness of cytoreductive nephrectomy
(CNx) with targeted therapy
Cytoreductive Nephrectomy
Rationale for CNx
• 90% of trial patients had a nephrectomy
• Palliative benefits: o May reduce hematuria, intractable pain, paraneoplastic symptoms, local
invasion/compression
• Inferred benefit from interferon randomized trial data
• Rare ‘complete response’ with CNx o Regression of metastatic lesions
Rationale for CNx

Patient Selection for Cytoreductive Nephrectomy
• Balance of Benefit and Risk • Prognostic Factors
o Relatively good prognosis
o Patient with ≤ 3 IMDC criteria appear to derive most benefit
• Tumour Factors o Feasible resection (acceptable morbidity)
o Tumour causing morbidity (eg thrombus, pain)
o Clear cell histology (no sarcomatoid)
o Consider biopsy if no histology available
o Tumour bulk (>75% of tumour can be resected with CN)
o No central nervous system or liver metastases
o Consider CT brain
o No unresected symptomatic metastases
Case Resolution
• Patient received cytoreductive nephrectomy followed by systemic therapy (tyrosine kinase inhibitor).
• No major surgery related complications.
Metastasectomy
Expert Opinion • Many cohorts but no RCTs
• n = 3600*
• Location of metastases in studies:
o Lung 60%
o Bone 30%
o Other 25%
• Synchronous metastases: 40%
• Solitary metastases: 36–87%
• Complete metastasectomy: 30%
• Incomplete metastasectomy: 25%

Metastasectomy
Expert Opinion
• Cohort studies: overall 5-year survival of 15%
• All groups had durable survivors
• Several prognostic factors identified
o Motzer criteria (anemia, hyperCa, PS, >LDH)
o Timing of metastases
o Number of metastases
o Location of metastases
o Completeness of metastasectomy
Breau RH, Blute ML, Surgery for renal cell carcinoma metastasis. Curr Opin Urol, 2010; 20: 375-3781.
Considerations for Metastasectomy
1) Location of Metastases
2) Morbidity of Resection
3) Completeness of Resection
4) Timing
Breau RH, Blute ML, Surgery for renal cell carcinoma metastasis. Curr Opin Urol, 2010; 20: 375-3781.
Location of Metastases
• Adrenal
• Pancreas
• Lung
• Bone
• Lymph nodes
• Brain
• Liver
• Multiple locations have worse outcomes – but not necessarily futile
All groups have long-term survivors
Breau RH, Blute ML, Surgery for renal cell carcinoma metastasis. Curr Opin Urol, 2010; 20: 375-3781.
Location of Metastases: Lung
• 6 cohorts o Largest cumulate reported experience
• 5-year survival: o Complete resection 40%
o Incomplete or no resection 15%
Breau RH, Blute ML, Surgery for renal cell carcinoma metastasis. Curr Opin Urol, 2010; 20: 375-3781.
Resection of Multiple Metastasis
Lung-only metastasis Non-lung-only metastasis
Alt AL, Boorjian SA, Lohse CM, Costello BA, Leibovich BC, Blute ML. Survival after complete surgical resection of multiple metastases from renal cell carcinoma. Cancer. 2011 Jul 1;117(13):2873-8.
Morbidity of Resection
• Morbidity of resection must be considered given unknown benefit
• Multidisciplinary surgical team recommended
Completeness of Resection
• Best responses in patients with complete resection
• Incomplete metastasectomy only for palliation
*Leibovich 2005, Naito 2009 1. Alt AL, Boorjian SA, Lohse CM, Costello BA, Leibovich BC, Blute ML. Survival after complete surgical resection of multiple metastases from renal cell carcinoma.

Journal of Urology, 2008 Sep. 180(3): 873.
Timing
• Prognosis: o Best: Late metachronous (>2 years)
o Intermediate: Synchronous (at time of diagnosis)
o Worst: Early metachronous
Breau RH, Blute ML, Surgery for renal cell carcinoma metastasis. Curr Opin Urol, 2010; 20: 375-3781.
Metastasectomy Summary
1) Location of Metastases o Lung and glandular organs favourable
2) Consider Morbidity of Resection
3) Complete Resection Important
4) Timing
Patient Follow-up
• Patient offered metastasectomy due to: o Favorable location (lung)
o Acceptable surgical risk
o Complete resection of all METs was feasible
o >2 years between nephrectomy and metastases
Case Conclusion
• Patient underwent complete metastasectomy of all 3 lung nodules
• No major peri-operative complications
• Currently no evidence of disease 2 years post-
metastasectomy

Monitoring During Second-Line Therapy
• Patients beyond 1st line therapy will need closer follow up:
o More symptoms due to cancer, so may be less
tolerant of side effects
o Increased risk of rapid progression
Patient Follow-up
• Patient tolerates 1st cycle well
• By end of 2nd cycle
o Increasing weight loss, anorexia, right upper quadrant pain, shortness of breath, ECOG 2
o Based on clinical decline, patient and family referred to palliative care
o Repeat imaging: new disease in liver and lungs and left adrenal gland
Case Resolution
• Patient deteriorates quickly over the next two weeks o ECOG = 3
• No further systemic therapy
• Patient dies peacefully at home
