The Impact

Objective: To evaluate the role of incomplete metastasectomy (IM) for patients with metastatic renal cell carcinoma (mRCC) on overall survival (OS) and time to introduction of first-line systemic therapy. Methodology: Patients diagnosed with mRCC between Jan 2011 and Apr 2019 in 16 centers were selected from the Canadian Kidney Cancer information system database. We included mRCC patients who had prior nephrectomy and had received an IM (resection of at least 1 metastasis) or no metastasectomy (NM). A propensity score matching was performed to minimize selection bias. Cox proportional hazards analysis was used to assess the impact of the metastasectomy while adjusting for potential confounders. OS was assessed by Kaplan-Meier analysis. Results: A total of 138 patients with mRCC underwent IM, while 1221 patients did not. On multivariate analysis, IM did not improve OS (hazard ratio [HR] 0.96, 95% CI 0.63 to 1.45, P = 0.836) However, subgroup analyses revealed IM improved OS compared with NM when lungs were the only site involved (median time to OS not reached versus 66 months, respectively; P = 0.014). Additionally, lung metastasectomy delayed the systemic therapy compared with NM (median 41 and 13 months, respectively, P = 0.014). IM of endocrine organs (thyroid, pancreas, adrenals) or bone metastases did not impact OS. Conclusion: The role of IM for mRCC is limited. Incomplete resection of lung metastases was associated with improved OS and delayed time to introduction of systemic therapy when lungs were the sole location of metastatic disease. Despite case-matching, unknown unadjusted confounders may explain the relationship between IM and survival in this analysis.

617 Background: Metabolic disruption is frequent in renal cell carcinoma (RCC). Loss of the mitochondrial fumarate hydratase (FH) enzyme is associated with enhanced glycolytic metabolism, angiogenesis and clinical aggressiveness in type 2 papillary RCC. However, FH expression has never been evaluated in clear cell RCC (ccRCC). In this study, we investigated the impact of FH expression on the outcomes of patients (pts) with metastatic ccRCC (mccRCC). Methods: We included pts with mccRCC, for whom formalin-fixed, paraffin embedded (FFPE) tissue from the primary tumor had been obtained before initiation of systemic treatment. FH levels were evaluated by immunohistochemistry (IHC), and were defined as “normal” if FH expression in most cancer cells was comparable to the adjacent normal tubular cells and “low” in the opposite case. We evaluated the association between FH levels and clinico-pathological characteristics through the chi-squared or Fisher’s exact test. The log-rank test was used to compare survival between patient subgroups. Results: We evaluated 49 mccRCC pts, of whom 36 (73.5%) had synchronous metastases. FH levels were normal in 29 (59.2%) pts and low in 20 (40.8%) pts. FH expression was not associated with patient age (p = 0.5), sex (p = 0.34), tumor grade (p = 0.66), T stage (p = 0.38), N stage (p = 0.88), metastatic disease at the time of diagnosis (p = 0.4), number of metastatic sites (p = 1) or sarcomatoid morphology (p = 0.36). 44 pts received first-line therapy with tyrosine kinase inhibitors (TKIs). In pts with low as compared to normal FH levels, median progression free survival (mPFS) during any first-line treatment was 34 and 10.1 months, respectively (HR 0.39, 95% CI 0.18-0.85; p = 0.014), while mPFS during first-line TKI therapy was 34 and 8.42 months, respectively (HR 0.4, 95% CI 0.17-0.94; p = 0.03). Median overall survival (OS) was not reached in pts with FH-low tumors, while it was 22.9 months in normally expressing ones (HR 0.14, 95% CI 0.032-0.63; p = 0.028). Conclusions: In mccRCC pts, low FH expression in primary tumors is associated with longer PFS during any first-line or TKI treatment, and also with better OS. This is the first study to reveal a prognostic and predictive role of FH levels in mccRCC.

Cytoreductive Nephrectomy

350 Background: The role of cytoreductive nephrectomy (CNx) in patients with metastatic renal cell carcinoma (mRCC) is currently in question. Assessing the benefits and risks of CNx is challenging, with a lack of validated prognostic tools. Biomarkers of the systemic inflammatory response have prognostic utility in mRCC and are included in the IMDC score used to predict survival in patients with mRCC treated with systemic therapy. We sought to investigate their role in patients with mRCC who had undergone CNx. Methods: A cohort of 68 patients, suitable for first-line VEGFR inhibitor (VEGFRi) systemic therapy, who had undergone CNx for mRCC, were identified from a clinical database of patients referred to a regional mRCC service. Inflammatory biomarkers from routine blood tests (haemoglobin, white cell count, neutrophil count, platelets, C-reactive protein (CRP), albumin) and the IMDC score, measured at the time of diagnosis of mRCC, were recorded. The relationship between these and overall survival and time to VEGFRi (tVEGFRi) was examined using Kaplan-Meier and Cox-regression methods. Results: Data were available for 68 patients. Median survival was 33.7 months. On multivariate analysis, albumin ( < 35g g/dL v ≥35 g/dL) and CRP (≤ 10 mg/L v > 10 mg/L) were independently associated with overall survival (p = 0.027 and p = 0.034 respectively). Albumin stratified survival from 24.7 to 87.2 months (p < 0.0001) and CRP from 29.4 to 82.3 months (p = 0.004). 40 (59%) patients subsequently commenced VEGFRi therapy. Median tVEGFRi was 18.1 months, with only 5 (7%) patients commencing treatment within 3 months. 16 (24%) patients yet to receive systemic therapy remain alive after a median 54.0 months follow-up. On multivariate analysis, albumin was also predictive of tVEGFRi (p = 0.037), stratifying tVEGFRi from 6.07 to 45.7 months (p = 0.002). Conclusions: These results highlight that biomarkers of the systemic inflammatory response are strong prognostic factors in mRCC patients who have undergone CNx. Albumin and CRP, but not IMDC, predict survival in this patient group. Significantly, the population investigated here differ from those included in the CARMENA and SURTIME studies, with a majority undergoing surveillance prior to VEGFRi therapy. Our results support a role for CNx in patients where deferred systemic therapy strategies may be employed. Albumin may assist in clinical decision making when considering when to start systemic therapy. We advocate further studies to investigate the prognostic role of these simple, routine clinical tests in patients with mRCC undergoing CNx.

Editor's Note: The following article is based on the 2016 ASCO Annual Meeting Education Session “Cytoreductive Nephrectomy in Renal Cell Carcinoma: A Debate.” The author reviews the pros and cons of cytoreductive nephrectomy and whether recent advances in systemic therapy warrant physicians to proceed directly to systemic therapy as in other metastatic solid tumors, without the integral step of cytoreductive nephrectomy.

Dismal Prognosis

It is widely accepted that renal cell carcinoma with liver metastasis carries a dismal prognosis. We aimed to explore the value of cytoreductive nephrectomy among these patients. Patients were extracted from the SEER database between 2010 and 2017. The univariate and multivariate Cox proportional hazards models were conducted to select the prognostic predictors of survival. Patients were divided into nephrectomy and non-nephrectomy groups. Propensity score-matching analyses were applied to reduce the above factors’ differences between the groups. Overall survival was compared by Kaplan-Meier (K-M) analyses. Data from 683 patients was extracted from the database. The univariate Cox regression and multivariate Cox regression revealed that factors including age, histologic type, T and N stages, lung metastasis, brain metastasis, and nephrectomy were significant predictors of survival in the patients. After the propensity score-matching analyses, we found that nephrectomy prolonged overall survival. Nephrectomy can prolong overall survival in eligible renal cell carcinoma patients with liver metastasis.
