Abstract

fetched live from OpenAlex

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.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
