Clinical Scorecard: The Effect of Initial Versus Sequential Chemoradiotherapy on Survival in Patients with Locally Advanced Esophageal Squamous Cell Carcinoma
At a Glance
Category Detail
Condition Locally advanced unresectable esophageal squamous cell carcinoma (ESCC)
Key Mechanisms Definitive chemoradiotherapy (DCRT) and immune checkpoint inhibitor (ICI)-based conversion therapies
Target Population Patients aged 18-85 with histologically confirmed ESCC and unresectable disease
Care Setting Multicenter study across three medical centers
Key Highlights
Salvage DCRT showed significantly improved overall survival (OS) compared to upfront DCRT. 1-year OS rates: 95.1% (salvage) vs. 56.9% (upfront). 2-year OS rates: 68.8% (salvage) vs. 36.6% (upfront). Objective remission rate (ORR) was higher in the salvage group (68.29%) than in the upfront group (26.00%). Median OS for the entire cohort was 24.6 months.
Guideline-Based Recommendations
Diagnosis
Histological confirmation of ESCC is required. Clinical evaluation of tumor stage (cT2–4 N0/N + M0 or M1).
Management
DCRT is the standard first-line treatment for locally advanced unresectable ESCC. Consider ICI-based conversion therapy prior to DCRT.
Monitoring & Follow-up
Assess overall survival (OS), event-free survival (EFS), progression-free survival (PFS), and objective remission rate (ORR).
Risks
Potential adverse effects from prior ICI therapy on subsequent DCRT efficacy.
Patient & Prescribing Data
Patients with unresectable locally advanced ESCC treated from January 2018 to May 2024.
Combination of ICIs with platinum-based chemotherapy followed by DCRT shows promise for improved outcomes.
Clinical Best Practices
Utilize a multidisciplinary treatment approach for managing locally advanced ESCC. Consider salvage DCRT for patients who do not respond to initial conversion therapy.
