On August 5, 2021, Yongling Ji and colleagues from the Cancer Hospital of the University of Chinese Academy of Sciences published the results of a Phase 3 clinical trial in the medical journal "JAMA Oncology." The study evaluated the efficacy and safety of TS-1 combined chemoradiotherapy in elderly patients aged 70-85 with esophageal cancer.
A total of 298 elderly patients with esophageal cancer, aged 70-85, participated in this randomized, open-label Phase 3 trial. They were randomized 1:1 to receive either TS-1 combined chemoradiotherapy or radiotherapy alone. The primary endpoint was the two-year overall survival (OS) rate.
The background of the 298 patients was as follows: 60.4% (N=180) were male. The median age in the chemoradiotherapy group was 77 years (range 74-79), and in the radiotherapy group, it was 77 years (range 74-80). Patients with Stage III or IV disease accounted for 50.7% (N=151). The results were as follows:
With a median follow-up of 33.9 months, the primary endpoint of two-year OS rate was 53.2% in the chemoradiotherapy group compared to 35.8% in the radiotherapy group, showing a significant improvement. The secondary endpoint of complete response rate was 41.6% versus 26.8%, respectively.
Regarding safety, apart from the incidence of Grade 3 or higher leukopenia, which was 9.5% in the chemoradiotherapy group versus 2.7% in the radiotherapy group, there were no significant differences in the incidence of other adverse events. The treatment-related mortality rate was 2.0% (N=3) in the chemoradiotherapy group and 2.7% (N=4) in the radiotherapy group.
Based on the results of this Phase 3 trial, Yongling Ji and colleagues stated that TS-1 combined chemoradiotherapy significantly improved overall survival in elderly patients with esophageal cancer, and the safety profile was manageable.
