There is no evidence that one treatment was superior to the other or could improve the outcome reported with ICT followed by RT alone (French Groupe Oncologie Radiothérapie Tête et Cou [GORTEC] 2000-01 trial [Induction CT by Cisplatin, 5FU With or Without Docetaxel in Patients With T3 and T4 Larynx and Hypopharynx Carcinoma]). The protocol that can best compare with RT alone after ICT is still to be determined.
Background: Real-world data on cabozantinib in metastatic renal cell carcinoma (mRCC) is limited. This study (CABOREAL) reports treatment patterns and outcomes for patients treated with cabozantinib through the French Early Access Program. Patients and methods: This multicentre (n Z 26), observational, retrospective study enrolled patients with mRCC who had received 1 dose of cabozantinib. Overall survival (OS) was estimated using the KaplaneMeier method; subgroups were compared using the log-rank test.A multiple Cox regression model assessed predictive factors of OS after cabozantinib initiation. Results: Four hundred and ten recruited patients started treatment between September 2016 and February 2018: the Eastern Cooperative Oncology Group Performance Status 2, 39.3%; poor International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) risk, 31.7%; 0e1, 2 and 3 previous treatment lines, 25.3%, 33.4% and 41.2%, respectively; bone metastases, 55.9%; brain metastases, 16.8%. Median (minemax) follow-up was 14.4 (0 e30) months. Overall, 57.0% of patients had a dose reduction, 15.6% an alternative dose schedule. The median average daily dose was 40.0 mg. Median (quartile [Q]1eQ3) treatment duration was 7.6 (0.1e29.1) months, median OS was 14.4 months, and the 12-month OS rate was 56.5% (95% confidence interval: 51.5e61.2). Most patients (54.4%) received subsequent treatment. Predictive factors associated with longer OS were body mass index 25 kg/m 2 (p Z 0.0021), prior nephrectomy (p Z 0.0109), favourable or intermediate IMDC risk (p < 0.0001) and cabozantinib initiation at 60 mg/day (p Z 0.0486). Conclusions: In the largest real-world study to date, cabozantinib was effective in unselected, heavily pretreated patients with mRCC. Initiation at 60 mg/day was associated with improved outcomes.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
