Sarcomatoid Differentiation

Background: Sarcomatoid differentiation/histology of renal cell carcinoma (sRCC) in patients with metastatic renal cell carcinoma (mRCC) is still underresearched in current therapy regimes. We aimed to evaluate the impact of sRCC on outcomes in patients with mRCC treated with tyrosine kinase inhibitors (TKIs).Methods: We collected complete data of 262 consecutive mRCC patients from our institutional database for this retrospective study. All patients were treated with TKIs within a single or multimodal treatment approach. All analyses were adjusted for the presence of sRCC. Descriptive statistics as well as uni- and multivariable outcome metrics, including progression-free (PFS) and overall survival (OS) as endpoints were performed.Results: Overall, 18 patients had sRCC (6.9%). Patients with sRCC had more often clear-cell histology (p = 0.047), a higher T-stage (p = 0.048), and underwent cytoreductive nephrectomy more frequently (p < 0.001). The most common first-line TKIs were Sunitinib (65.6%), Sorafenib (19.5%), and Pazopanib (10.3%), respectively. At a median follow-up of 32 months, patients with sRCC had significantly reduced PFS (p = 0.02) and OS (p = 0.01) compared to patients without sRCC. In multivariable analyses that adjusted for the effects of standard mRCC predictors, the sarcomatoid feature retained its independent association with inferior PFS (HR: 2.39; p = 0.007) and OS (HR: 2.37; p = 0.001). This association remained statistically significant in subgroup analyses of patients with Sunitinib as first-line therapy (PFS p < 0.001; OS: p < 0.001).Conclusion: Despite its rare occurrence, our findings confirm sRCC as a powerful predictor for inferior outcomes in mRCC treated with targeted therapies. This suggests a need for more tailored treatment strategies in patients harboring mRCC with sarcomatoid histology to improve oncological outcomes.

Background: We performed a retrospective population-based studyto assess the impact of tyrosine kinase inhibitors (TKIs) on overallsurvival (OS) in patients treated for metastatic renal cell carcinoma(mRCC) in Alberta, Canada and to assess the impact of nephrectomyon OS in patients treated with TKIs.Methods: We identified 134 patients who began taking a TKIbetween December 2003 and June 2007 for mRCC in Alberta. Wecompared survival in this group to that in an earlier cohort of141 pa tients treated with interferon-α (IFN-α) between May 1995and March 2003. We used the Kaplan–Meier method to determineOS, and we used a Cox proportional hazards model to determinehazard ratios (HRs) and confidence intervals (CIs). We performedmultivariate analysis to assess the impact of neprhectomy on OS.Results: Of the 134 patients treated with TKIs, 81 received treatmentin the first-line setting, whereas 53 received treatment after priorIFN-α therapy. All 141 patients from the IFN-α cohort receivedtreatment in the first-line setting. Patients treated with TKIs had animproved OS compared with the IFN-α cohort (HR 0.61, 95% CI0.45–0.83, p = 0.001). The median OS was 18 months in the TKIgroup and 10 months in the IFN-α group. The benefit of TKIs wasconfined to favourable and intermediate risk groups according tothe Memorial Sloan-Kettering Cancer Center prognostic model.Prior nephrectomy was associated with improved OS in the TKIcohort, independent of other prognostic factors.Conclusion: Tyrosine kinase inhibitors improve OS compared withIFN-α in mRCC. In patients treated with TKIs, prior nephrectomyis associated with improved survival independent of other prognosticvariables.Contexte : Une étude rétrospective de population a été menée afind’évaluer l’effet des inhibiteurs de la tyrosine-kinase (ITK) sur lasurvie globale (SG) des patients atteints d’un néphrocarcinomemétastatique et d’évaluer l’impact d’une néphrectomie sur la SGdes patients traités par ITK.Méthodes : Cent trente-quatre patients en Alberta ont entrepris untraitement par ITK entre decembre 2003 et juin 2007 en raisond’un néphrocarcinome. On a comparé les taux de survie dans cegroupe avec ceux d’un groupe de 141 patients ayant entrepris untraitement de première intention par IFN-α entre mai 1995 et mars2003. La survie globale a été calculée à l’aide de la méthode deKaplan Meier, et le risque relatif (RR) et les intervalles de confiance(IC) ont été calculés à l’aide du modèle des risques proportionnelsde Cox. Une analyse multivariée a permis d’évaluer l’impact dela néphrectomie sur la SG dans la population globale de l’étuded’une part et chez les patients traités par ITK d’autre part.Résultats : Les 134 patients ayant entrepris un traitement par ITK ontété répartis ainsi : traitement de première intention, 81 patients, ettraitement de seconde intention après un traitement par IFN-α,53 patients. Les patients traités par ITK ont montré une SG supérieurepar rapport aux patients traités par IFN-α (RR 0,61, IC à 95 % 0,45–0,83, p = 0,001). La SG médiane était de 18 mois chez les patientstraités par ITK et de 10 mois chez les patients traités par IFN-α. Letraitement par ITK n’a eu un avantage que chez les patients atteintsde néphrocarcinome métastatique présentant un risque faible ouintermédiaire selon le modèle du Memorial Sloan-Kettering CancerCener. Une néphrectomie antérieure a été associée à une meilleureSG dans la cohorte traitée par ITK, indépendamment des autres facteurspronostics.Conclusion : Le traitement par ITK a amélioré la SG par rapport autraitement par IFN-α dans une population « réelle ». Une néphrectomieantérieure a été associée à une SG supérieure chez lespatients traités par ITK.

The Impact

Background: The Memorial Sloan–Kettering Cancer Center (MSKCC) prognostic model has been widely used for the prediction of the outcome of metastatic renal cell carcinoma (mRCC) patients treated with systemic therapies, however, data from large studies are limited. This study aimed at the evaluation of the impact of the MSKCC score on the outcomes in mRCC patients treated with first-line sunitinib, with a focus on the intermediate-risk group. Methods: Clinical data from 2390 mRCC patients were analysed retrospectively. Progression-free survival (PFS), overall survival (OS), and objective response rate (ORR) were analysed according to the MSKCC risk score. Results: ORR, median PFS, and OS for patients with one risk factor were 26.7%, 10.1, and 28.2 months versus 18.7%, 6.2, and 16.2 months, respectively, for those with two risk factors (ORR: p = 0.001, PFS: p < 0.001, OS: p < 0.001). ORR, median PFS, and OS were 33.0%, 17.0, and 44.7 months versus 24.1%, 9.0, and 24.1 months versus 13.4%, 4.5, and 9.5 months in the favourable-, intermediate-, and poor-risk groups, respectively (ORR: p < 0.001, PFS: p < 0.001, OS: p < 0.001). Conclusions: The results of the present retrospective study demonstrate the suitability of the MSKCC model in mRCC patients treated with first-line sunitinib and suggest different outcomes between patients with one or two risk factors.

Real World Data

The standards of treatment for metastatic renal cell carcinoma (mRCC) have changed significantly from unsuccessful attempts of radiation and cytostatic therapy to the encouraging results of targeted therapy and specific immunotherapy. Sunitinib has got into the practice in 2006, and now it`s one of the most studied and approved. Sunitinib is one of the first oral targeted drugs for RCC. It affects such receptors as VEGFR1, 2, 3; PDGFR, FGFR, c-KIT, and RET, which take part in the pathologic angiogenesis, tumor growth, and metastasizing. Moreover, sunitinib stimulates the growth and development of lymphatic vessels, that deliver immunocytes to the tumor. The advantage of sunitinib over non-specific immunotherapy has been proven by Motzer et al. The randomized trials COMPARZ, RECORD-3, and SWITCH have confirmed that sunitinib is more effective than several targeted drugs (pazopanib, everolimus, and sorafenib respectively) as the first line of treatment for mRCC. The randomized trial of the 3rd phase CARMENA has demonstrated the importance of sunitinib monotherapy for mRCC of intermediate and poor prognosis. In general, sunitinib has been proven to be an effective first-line drug for mRCC, as it`s evidenced in the comprehensive metaanalysis of real-world data and randomized controlled trials published between 2000 and 2017. Nowadays, despite the success of the immunotherapeutic direction, tyrosine kinase inhibitors, and particularly sunitinib, rightfully remain the standard for mRCC of favourable prognosis, the treatment option for worse prognosis in case of contraindications for other methods of therapy, and it` s also used in subsequent therapy lines.

Tyrosine kinase inhibitors still play a very important role in the treatment of metastatic renal cell carcinoma despite a continuously changing scenario, in which immunotherapy and several combination-based approaches are also available. In this light, patient-reported outcomes and health-related quality of life are important factors in the selection of the best first-line treatment. This Review focuses on the existing evidence on patient-reported outcomes and health-related quality of life with several tyrosine kinase inhibitors (pazopanib, sunitinib, cabozantinib and tivozanib) used as first-line treatment for metastatic renal cell carcinoma.
