In the phase 3 CLEAR trial, lenvatinib plus pembrolizumab (L + P) showed superior efficacy versus sunitinib in treatment-naïve patients with advanced renal cell carcinoma (aRCC). The combination treatment was associated with a robust objective response rate of 71%. Here we report tumor responses for patients in the L + P arm in CLEAR, with median follow-up of ∼4 yr at the final prespecified overall survival (OS) analysis. Tumor responses were assessed by independent review using Response Evaluation Criteria in Solid Tumors v1.1. Patients with a complete response (CR; n = 65), partial response (PR) with maximum tumor shrinkage ≥75% (near-CR; n = 59), or PR with maximum tumor shrinkage <75% (other PR; n = 129), were characterized in terms of their baseline characteristics. The median duration of response was 43.7 mo (95% confidence interval [CI] 39.2-not estimable) for the CR group, 30.5 mo (95% CI 22.4-not estimable) for the near-CR group, and 17.2 mo (95% CI 12.5-21.4) for the other PR group. The 36-mo OS rates were consistently high in the CR (97%), near-CR (86%), and other PR (62%) groups. Robust objective response rates were observed across International Metastatic RCC Database Consortium favorable-risk (69%, 95% CI 60-78%), intermediate-risk (73%, 95% CI 67-79%), and poor-risk (70%, 95% CI 54-85%) subgroups. The robust response to L + P supports this combination as a standard-of-care first-line treatment for patients with aRCC. PATIENT SUMMARY: The CLEAR trial enrolled patients with advanced kidney cancer who had not previously received any treatment for their cancer. Here we report results for tumor shrinkage observed in the group that received lenvatinib plus pembrolizumab combination treatment during the trial. Shrinkage of target tumors with this combination was long-lasting and was observed in patients irrespective of their disease severity. This trial is registered on ClinicalTrials.gov as NCT02811861., (Copyright © 2024 The Author(s). Published by Elsevier B.V. All rights reserved.)

Background: Preserving health-related quality of life (HRQOL) is an important goal during renal cell carcinoma treatment. We report HRQOL outcomes from a phase II trial (NCT03173560)., Patients and Methods: HRQOL data were collected during a multicenter, randomized, open-label phase II study comparing the safety and efficacy of 2 different starting doses of lenvatinib (18 mg vs. 14 mg daily) in combination with everolimus (5 mg daily), following one prior vascular endothelial growth factor-targeted treatment. HRQOL was measured using 3 different instruments-FKSI-DRS, EORTC QLQ-C30, and EQ-5D-3L-which were all secondary endpoints. Change from baseline was assessed using linear mixed-effects models. Deterioration events for time to deterioration (TTD) analyses were defined using established thresholds for minimally important differences in the change from baseline for each scale. TTD for each treatment arm was estimated using the Kaplan-Meier method., Results: Baseline characteristics of the 343 participants randomly assigned to 18 mg lenvatinib (n = 171) and 14 mg lenvatinib (n = 172) were well balanced. Least-squares mean estimates for change from baseline were favorable for the 18 mg group over the 14 mg group for the FKSI-DRS and most EORTC QLQ-C30 scales, but differences between treatments did not exceed the minimally important thresholds. Median TTD was longer among participants in the 18 mg group than those in the 14 mg group for most scales., Conclusions: Participants who received an 18 mg lenvatinib starting dose had favorable HRQOL scores and longer TTD on most scales compared with those who received a 14 mg starting dose., (© The Author(s) 2022.

Aim: Much attention has been paid to conversion therapy for stage IV gastric cancer, however, its operative comorbidities and survival benefit have not yet been clarified. CONVO-GC-1, an international retrospective cohort study, was designed to investigate the role of conversion surgery in Japan, Korea, and China., Methods: The rate of operative complications was the primary endpoint and the overall survival (OS), according to the four-category criteria previously published (Gastric Cancer:19; 2016), was analyzed as the secondary endpoint., Results: A total of 1206 patients underwent surgery after chemotherapy with curative intent. Operative complications were observed in 290 (24.0%) patients in all grades, including pancreatic fistula and surgical site infection. The median survival time (MST) of all resected patients was 36.7 mo (M) and those of R0, R1, and R2 resection were 56.6 M, 25.8 M, and 21.7 M, respectively. Moreover, the MST of R0 patients were 47.8 M, 116.7 M, 44.8 M in categories 1, 2, and 3, respectively, and not reached in category 4. Interestingly, the MST of P1 patients was as favorable as that of P0CY1 patients if R0 resection was achieved. The MST of patients with liver metastasis was also favorable regardless of the number of lesions, and the MST of patients with para-aortic lymph node (LN) No 16a1/b2 metastasis was not inferior to that of patients with para-aortic LN No 16a2/b1 metastasis., Conclusion: Conversion therapy for stage IV gastric cancer is safe and could be a new therapeutic strategy to improve the survival of patients, especially those with R0 resection., (© 2021 The Authors.
