Effektivitet og sikkerhed af adebrelimab kombineret med kemoradioterapi hos patienter med ikke -omsættelig lokalt avanceret eller postoperativ tilbagevendende esophageal pladecellekarcinom

29. september 2026 opdateret af: Nanfang Hospital, Southern Medical University

En klinisk fase II -undersøgelse af effektiviteten og sikkerheden af ​​adebrelimab kombineret med kemoradioterapi hos patienter med ikke -omsættelig lokalt avanceret eller postoperativ tilbagevendende esophageal pladecellecarcinom

This study was a multi-center, single-arm, open-label phase II clinical trial. Thirty patients with unresectable locally advanced or postoperative recurrent esophageal squamous cell carcinoma were treated with concurrent chemoradiotherapy combined with immunotherapy. The radiotherapy regimen was intensity-modulated radiotherapy with PGTV at 50-50.4 Gy/25-28 fractions, 1.8-2 Gy per fraction, five times a week. The chemotherapy regimen was paclitaxel 50 mg/m2 and cisplatin 25 mg/m2 intravenous infusion on day 1, once a week for five times. The immunotherapy was with adebutilimab at 1200 mg on day 1, every three weeks for three times. One week before radiotherapy, gastroscopy, chest CT or PET-CT images were taken as the baseline standard. Based on the results of gastroscopy, chest CT or PET-CT before and after treatment, the number of patients with complete response (CR), partial response (PR), stable disease (SD) and progressive disease (PD) in the two groups was observed. The objective response rate (ORR) was calculated as CR + PR, and the disease control rate (DCR) was calculated as CR + PR + SD. The progression-free survival (PFS), overall survival (OS), 1-year and 2-year survival rates and adverse reactions were also statistically analyzed.

Foranstaltningsbeskrivelse
Tidsramme
Objective response rate at 3 months after radiotherapy (ORR)
Tidsramme: Three months after radiation

ORR includes Complete Response (CR) and Partial Response (PR) according to accepted response evaluation criteria (such as solid tumor RECIST version 1.1), (1) Complete response (CR) : Except for nodular disease, all target lesions disappeared completely. All target nodules must be reduced to normal size (short axis < 10 mm). All target lesions must be evaluated. (2) Partial response (PR) : Total diameter of all measurable target lesions is ≥ 30% below baseline. The short diameter was used for the sum of the target nodules, while the longest diameter was used for the sum of all other target lesions. All target lesions must be evaluated.
