Project description:Historically, immediate cytoreductive nephrectomy (CN) was considered the standard of care in patients with metastatic renal cell carcinoma (mRCC) who were fit enough to undergo surgery. Recently, 2 randomized controlled trials, SURTIME and CARMENA, have questioned the role of immediate CN and initiated an ongoing debate on the proper indications and timing of CN. Although some patients still benefit from immediate CN, other patients require immediate systemic treatment, and some of them might benefit from deferred CN in the absence of disease progression. This study provides an overview of the history of CN, an in-depth analysis of SURTIME and CARMENA, and highlights the current indications for performing immediate or deferred CN.
Project description:The management of metastatic renal cell carcinoma (mRCC) continues to be a therapeutic challenge; however, the options for systemic therapy in this setting have exploded over the past 20 years. From the advent of toxic cytokine therapy to the subsequent discovery of targeted therapy (TT) and immune checkpoint inhibitors, the landscape of viable treatment options continues to progress. With the arrival of cytokine therapy, two randomized trials demonstrated a survival benefit for upfront cytoreductive nephrectomy (CN) plus interferon therapy and this approach became the standard for surgical candidates. However, it was difficult to establish the role and the timing of CN with the subsequent advent of TT, just a few years later. More recently, two randomized phase III studies completed in the TT era questioned the use of CN and brought to light the role of risk stratification while selecting patients for CN. Careful identification of the mRCC patients who are likely to have a rapid progression of the disease is essential, as these patients need prompt systemic therapy. With the continued advancement of systemic therapy using the immune checkpoint inhibitors as a first line therapy, the role of CN will continue to evolve.
Project description:This retrospective, five-multicenter study was aimed to evaluate the prognostic impact of pathologic nodal positivity on recurrence-free (RFS), metastasis-free (MFS), overall (OS), and cancer-specific (CSS) survivals in patients with non-metastatic renal cell carcinoma (nmRCC) who underwent either radical or partial nephrectomy with/without LN dissection. A total of 4236 nmRCC patients was enrolled between 2000 and 2012, and followed up through the end of 2017. Survival measures were compared between 52 (1.2%) stage pT1-4N1 (LN+) patients and 4184 (98.8%) stage pT1-4N0 (LN-) patients using Kaplan-Meier analysis with the log-rank test and Cox regression analysis to determine the prognostic risk factors for each survival measure. During the median 43.8-month follow-up, 410 (9.7%) recurrences, 141 (3.3%) metastases, and 351 (8.3%) deaths, including 212 (5.0%) cancer-specific deaths, were reported. The risk factor analyses showed that predictive factors for RFS, CSS, and OS were similar, whereas those of MFS were not. After adjusting for significant clinical factors affecting survival outcomes considering the hazard ratios (HR) of each group, the LN+ group, even those with low pT stage, had similar to or worse survival outcomes than the pT3N0 (LN-) group in multivariable analysis and had significantly more relationship with RFS than MFS. All survival measures were significantly worse in pT1-2N1 patients (MFS/RFS/OS/CSS; HR 4.12/HR 3.19/HR 4.41/HR 7.22) than in pT3-4N0 patients (HR 3.08/HR 2.92/HR 2.09/HR 3.73). Therefore, LN+ had an impact on survival outcomes worse than pT3-4N0 and significantly affected local recurrence rather than distant metastasis compared to LN- in nmRCC after radical or partial nephrectomy.
Project description:Introduction: Renal cell carcinoma (RCC) found during pregnancy is rare. Treatment strategies and timing of surgeries are controversial. Retroperitoneal laparoscopic partial nephrectomy for T2 RCC during pregnancy has not been reported before. Patient Concerns and Diagnosis: Herein, we report a case of T2 RCC found in a 36-year-old woman during her 21st week of pregnancy. Both ultrasound and magnetic resonance imaging (MRI) suggested a malignancy, possibly renal cell carcinoma. Interventions and Outcomes: After discussion with a multidisciplinary team, the tumor was removed completely via retroperitoneal laparoscopic partial nephrectomy, and pathology result was clear cell RCC. A male infant was delivered full-term uneventful, and both the patient and the boy were in good health after a 46-month follow-up. Conclusion: Partial nephrectomy with retroperitoneal laparoscopic technique is feasible and recommended in some T2 RCC patients.
Project description:BackgroundThere is limited and controversial evidence on the prognosis of partial nephrectomy (PN) versus radical nephrectomy (RN) in patients with T3aN0/xM0 renal cell carcinoma (RCC) upstaged from clinical T1 RCC. In this study, we aimed to assess the prognosis difference following PN versus RN in patients with ≤7 cm T3aN0/xM0 RCC.MethodsFrom the Surveillance, Epidemiology, and End Results database, a total of 3196 patients receiving treatment of PN/RN for ≤7 cm T3aN0/xM0 RCC with only extrarenal fat extension in 2010-2017 were identified. An inverse probability of treatment weighting (IPTW)-adjusted cause-specific Cox model with hazard ratio (HR) and 95% confidence interval (CI) was used for overall survival (OS) and cancer-specific survival (CSS) analyses. Sensitivity analysis was based on the propensity score matching of PN and RN groups and from the dataset of 2010-2013.ResultsA total of 872 patients underwent PN, compared with 2324 undergoing RN. After IPTW adjustment, there was no significant difference in preoperative baseline characteristics between the PN and RN cohorts. Patients who underwent RN had worse OS (HRIPTW-adjusted , 1.46; 95% CI, 1.16-1.84; p = 0.001) and comparable CSS (HRIPTW-adjusted , 1.03; 95% CI, 0.64-1.66; p = 0.890) than those receiving PN in all cohorts and subgroups with T3a RCC of ≤4 cm and perinephric fat extension. Further, in patients with 4-7 cm T3a RCC with perinephric-fat invasion and all sizes of T3a RCC with sinus/perisinus fat extension, PN led to comparable OS and CSS. Sensitivity analyses validated these results.ConclusionPN provides comparable CSS and OS or even better OS than RN for patients with RCC ≤7 cm T3aN0/xM0. Although our study has some limitations, our results indicated that PN might oncologically safe for clinical T1 RCC, even confirmed a pathologically T3a upstaging post-PN.
Project description:Cytoreductive nephrectomy has been an integral part of management in metastatic renal cell carcinoma for patients with good performance status, based on the benefit shown by prospective trials in the interferon era and retrospective trials in the targeted therapies era. Clinical Trial to Assess the Importance of Nephrectomy (CARMENA), the first prospective phase III trial comparing a targeted agent alone (sunitinib) versus nephrectomy plus sunitinib, has been recently published, showing non-inferiority for the nephrectomy-sparing arm. In this article, we discuss the impact of nephrectomy including its immune-mediated effects, surgical morbidity and mortality, and the clinical data supporting the indications of nephrectomy in order to analyze the CARMENA trial in context, with the aim to identify optimal strategies for different patient populations in the metastatic setting.
Project description:In the past decades, several treatments have been proposed for the management of metastatic renal cell carcinoma (mRCC). Among these, cytoreductive nephrectomy (CN) represents a controversial and open issue in the era of targeted therapy and novel immunotherapy with immune checkpoint inhibitors. Two important studies, CARMENA and SURTIME, analyzed therapy with sunitinib with or without CN, and immediate CN followed by sunitinib versus a deferred CN after three cycles of sunitinib, respectively. CARMENA showed the non-inferiority of sunitinib alone versus sunitinib plus CN, whereas SURTIME showed no difference in progression-free survival (PFS), but a better median OS among patients with deferred CN. Therefore, more prospective clinical trials and appropriate patient identification are necessary to support CN in this new scenario. This review provides a snapshot of the current evidence for CN in mRCC, discusses the management strategies, and offers perspectives on the direction of future research.
Project description:The use of cytoreductive nephrectomy (CRN) in the targeted therapy era is still debated. We aimed to determine factors associated with reduced use of CRN and determine the effect of CRN on overall survival in patients with metastatic renal cell carcinoma (RCC). All advanced RCC diagnosed between 2001 and 2009 in New South Wales, Australia, were identified from the Central Cancer Registry. Records of treatment and death were electronically linked. Follow-up was to the end of 2011. Multivariable logistic regression analysis was used to determine factors associated with the receipt of CRN. Cox proportional hazards model was used to determine factors associated with survival. A total of 1062 patients were identified with metastatic RCC of whom 289 (27%) received CRN. There was no difference in the use of CRN over the time period of the study. Females (OR 0.68 (95% CI: 0.48-0.96)), unmarried individuals (OR 0.68 (95% CI: 0.48-0.96)), treatment in a nonteaching hospital (OR 0.26 (95% CI: 0.18-0.36)) and individuals without private insurance (OR 0.29 (95% CI: 0.20-0.41)) all had reduced likelihood of receiving CRN. On multivariable analysis, not receiving CRN resulted in a 90% increase in death (HR 1.90 (95% CI: 1.61-2.25)). In addition, increasing age (P < 0.001), increasing Charlson comorbidity status (P = 0.002) and female gender also had a significant independent association with death. Despite a strong association with improved survival, individuals who are elderly, female, have treatment in a nonteaching facility or have no private insurance have a reduced likelihood of receiving CRN.
Project description:We present a 55-year-old male, with good performance status who was diagnosed with a case of metastatic renal cell carcinoma following a pathologic femur fracture. Despite good performance status, multifocal metastases and poor-prognostic features portended a grim prognosis with predicted overall survival of less than nine months. On initial presentation, he was excluded from cytoreductive nephrectomy based on brain metastasis and interleukin-2 was not pursued as the primary tumor was to be left in situ. The patient was reconsidered for cytoreductive nephrectomy after sustained response to fifth line targeted therapies with shrinkage of tumor burden. The post-operative course was uneventful and the patient was discharged home on postoperative day one. Temsirolimus was resumed one week after surgery and the patient reported returning to his normal activities at the two week follow-up visit. We highlight important clinical features of metastatic renal cell carcinoma, the surgical considerations for cytoreductive nephrectomy and the detailed multidisciplinary care the patient received throughout this case report.
