Liver Resection for Metastases from Renal Cell Carcinoma
ABSTRACT This study was conducted to evaluate the safety and efficacy of liver resection in patients with hepatic metastases from renal cell carcinoma and to identify selection criteria for patients suitable for resection.
Between January 1988 and March 2006, 31 patients underwent liver resection for metastases from renal cell carcinoma. Patients were identified from a prospective database and retrospectively reviewed. Patient, tumor, and operative parameters were analyzed for their influence on long-term survival.
The overall 1-, 3- and 5-year survival rates were 82.2%, 54.3%, and 38.9%, respectively. One patient was deceased and 4 developed complications during the postoperative course. In the univariate analysis, site of the primary tumor (P = 0.013), disease-free interval (P = 0.012), and resection margins (P = 0.008) showed significant influence on long-term survival. In the multivariate analysis, only the resection margins were identified as an independent prognostic factor after liver resection.
Liver resection is effective and safe in the treatment of patients with hepatic metastases from renal cell carcinoma and offers the chance of long-term survival and cure. Achieving a margin-negative resection is the most important criterion in the selection of suitable patients for liver resection. However, the number of patients in the present study was small, and investigations of larger series may provide further prognostic parameters in these patients.

ABSTRACT: Despite early renal carcinoma diagnosis is more frequent nowadays, ~25-30 % of patients have metastatic disease at presentation and another ~30 % develop recurrent or metastatic disease after radical treatment for localized disease. In recent years, treatment of renal carcinoma is increasing in complexity due to the inclusion of a number of effective systemic treatments prolonging survival and increasing the therapeutic strategies for tumor debulking, or even achieving surgical complete responses and prolonged disease-free intervals. Initial multimodal approaches with immunotherapeutic agents are now being validated in patients treated with the new-targeted agents. Patients are now able to receive an optimal therapeutic strategy seeking a longer survival with an acceptable life quality and avoiding unnecessary comorbidities. In this context and as an initial therapeutic approach, it is imperative to promote patients' selection with established prognostic models within a multidisciplinary team to assess the recommendation of a cytoreductive nephrectomy (CN), metastasectomy, and/or systemic treatment. In the context of mRCC, when feasible and in patients with favorable prognostic factors, the strategy should be to consider a CN or metastasectomy for tumor debulking in order to achieve free intervals of prolonged disease. By contrast, it is recommended to evaluate whether to perform a biopsy for histological diagnosis without nephrectomy in the following situations: high surgical risk, bulky metastatic disease or in specific sites (brain or liver) or ECOG PS 3/4. The following review covers from initial to recent studies on the integration of systemic treatment and surgery in the context of metastatic disease for an optimal multimodal management in renal carcinoma.Current Treatment Options in Oncology 03/2015; 16(3):337.

ABSTRACT: Background: Metastatic renal cell carcinoma (RCC) to the liver portrays a poor prognosis and liver directed therapy remains controversial. We aimed to determine potential selection criteria for patients who might benefit from this strategy. Materials and Methods: We evaluated 247 consecutive patients with RCC metastatic to the liver from a prospectively maintained database. Results: Eighteen patients received liver directed therapy (18/247, 7%). Ten patients underwent liver resection (10/247, 4%) and eight patients underwent radiofrequency ablation (RFA, 8/247, 3%). All were rendered free of disease in the liver. Five had synchronous liver disease and underwent synchronous resections with their primary. Mortality was 0%. Fourteen had single (surgery 7, RFA 7) and four (surgery 3, RFA 1) had multiple liver lesions, respectively. Median size of lesions was 5cm (0.5 - 10cm) and 2.5cm (1 - 6cm) in the surgery and RFA groups, respectively. Median DFI was 10 months, and no difference was observed in those with a longer vs. shorter than median DFI (p = 0.95); liver specific progression free survival for the surgery and RFA groups were 4 and 6 months, respectively (p= 0.93). 1, 3 and 5-year actuarial survivals for the whole group were 89%, 40%, 27%. Median survival for the surgery group was 24 (3 to 254+) months, and for the RFA group 15.6 (7-56+) months (p = 0.56). Metachronous liver disease was associated with prolonged survival (p = 0.02). Conclusions: Liver directed therapy for RCC is safe. For highly selected patients with metachronous liver RCC metastases, liver directed therapy should be considered in a multidisciplinary manner.Journal of Cancer 04/2012; 3:184-90.

ABSTRACT: To evaluate outcomes of surgical treatment in patients with hepatic metastases from renal-cell carcinoma in the Netherlands, and to identify prognostic factors for survival after resection. Renal-cell carcinoma has an incidence of 2,000 new patients in the Netherlands each year (12.5/100,000 inhabitants). According to literature, half of these patients ultimately develop distant metastases with 20% involvement of the liver. Resection of renal-cell carcinoma liver metastases (RCCLM) is performed in only a minority of patients. Hence, little is known about outcome of resectable RCCLM. Patients were retrieved from local databases of the Netherlands Task Force for Liver Surgery (14 centers) and from the Dutch collective pathology database. Survival and prognostic factors were determined by Kaplan-Meier analysis and log rank test. Thirty-three patients were identified who underwent resection (n = 29) or local ablation (n = 4) of RCCLM in the Netherlands between 1990 and 2008. These patients comprise 0.5% to 1% of the total population of patients diagnosed with RCCLM in that period. There was no operative mortality. The overall survival at 1, 3, and 5 years was 79, 47, and 43%, respectively. Metachronous metastases (n = 23, P = 0.03) and radical resection (n = 19, P < 0.001) were statistically significant prognosticators of overall survival. Size < 50 mm (n = 18, P = 0,54), solitary metastases (n = 19, P = 0.93), and presence of extrahepatic metastases (n = 11, P = 0.28) did not have a statistically significant impact on survival. The favorable 5-year survival rate of 43% without operative mortality as found in this nationwide study indicates that selected patients with RCCLM can benefit from surgical treatment.Annals of Surgical Oncology 02/2011; 18(7):1932-8.
