Long-term survival and post-hoc analysis of toripalimab plus definitive chemoradiotherapy for oesophageal squamous cell carcinoma: insights from the EC-CRT-001 phase II trial.

ABSTRACT:

Background

In the EC-CRT-001 phase II study, the combination of toripalimab (an anti-programmed death-1 antibody) and definitive chemoradiotherapy (CRT) has shown promising efficacy in patients with locally advanced oesophageal squamous cell carcinoma (ESCC). Here, we reported the long-term outcomes and post-hoc exploratory analyses.

Methods

This single-arm, phase II trial enrolled 42 patients diagnosed with unresectable stage I-IVA ESCC was conducted at Sun Yat-sen University Cancer Center between November 2019 and January 2021. Treatment consisted of chemotherapy (weekly 50 mg/m² of paclitaxel and 25 mg/m² of cisplatin for five cycles), concurrent radiotherapy (50.4 Gy in 28 fractions), and toripalimab (240 mg every 3 weeks for up to 1 year).
