Induction Chemo-Immunotherapy + Radiotherapy vs Concurrent Chemoradiotherapy for Unresectable Locally Advanced Esophageal Squamous Cell Carcinoma
Efficacy and Safety of Induction Chemo-Immunotherapy Followed by Radiotherapy vs Concurrent Chemoradiotherapy in Unresectable Locally Advanced Esophageal Squamous Cell Carcinoma: A Randomized, Two-Arm, Phase II Study

Detaillierte Beschreibung
This is a prospective, randomized, two-arm, phase II clinical trial investigating induction chemo-immunotherapy followed by sequential radiotherapy versus concurrent chemo-immunotherapy plus radiotherapy in patients with unresectable locally advanced esophageal squamous cell carcinoma (ESCC).
Current standard of care for unresectable locally advanced ESCC is definitive concurrent chemoradiotherapy. However, outcomes remain suboptimal, with high rates of local recurrence and distant metastasis. The addition of PD-1 inhibitors to concurrent chemoradiotherapy has shown promising activity in recent studies, but optimal sequencing and integration of immunotherapy with radiotherapy are still under investigation.
This trial is designed to evaluate whether an induction strategy with chemo-immunotherapy followed by radiotherapy can improve response rates and long-term survival compared to the standard concurrent approach. Patients will be randomized to receive either:
- Experimental arm: Three cycles of induction chemo-immunotherapy, followed by definitive thoracic radiotherapy, then maintenance immunotherapy for up to one year.
- Control arm: Concurrent chemo-immunotherapy plus definitive thoracic radiotherapy, followed by maintenance immunotherapy for up to one year.
The primary objective is to compare the efficacy of the two regimens in terms of complete response and progression-free survival. Safety, tolerability, and quality of life will also be assessed to support the risk-benefit profile of each strategy.

|---|---|
|
Experimental: Experimental Group: Chemo-Immunotherapy Induction + Radiotherapy + PD-1 Maintenance
Patients receive 3 cycles of PD-1 antibody plus chemotherapy induction therapy, followed by thoracic radiotherapy (50.4Gy in 28 fractions), then PD-1 antibody maintenance therapy (200mg IV q3w, up to 1 year).
|
Paclitaxel 150-175 mg/m² combined with cisplatin 75 mg/m² or carboplatin AUC 5 (maximum 600 mg), administered intravenously every 3 weeks for 3 cycles, concurrent with PD-1 antibody induction therapy for unresectable stage III-IVA esophageal squamous cell carcinoma.
|
|
Aktiver Komparator: Control Group: Concurrent Chemoradiotherapy + PD-1 Maintenance
Patients receive weekly paclitaxel + cisplatin/carboplatin concurrent with thoracic radiotherapy (50.4Gy in 28 fractions), then PD-1 antibody maintenance therapy (200mg IV q3w, up to 1 year).
|
Paclitaxel 50 mg/m² combined with cisplatin 25 mg/m² or carboplatin AUC 5 (maximum 600 mg), administered intravenously once weekly for 5 cycles, concurrent with thoracic radiotherapy (50.4Gy in 28 fractions) for unresectable stage III-IVA esophageal squamous cell carcinoma.
