Spots Global Cancer Trial Database for A Multicenter, Randomized Controlled, Phase II Clinical Study of First-line Chemotherapy and Camrelizumab With or Without Radiotherapy in the Treatment of Oligometastatic Esophageal Cancer

Study Description

Brief Summary: A multi-center, open, randomized controlled, phase II clinical study to evaluate the efficiency and safety of chemotherapy and immunotherapy combined with locol radiotharepy in treatment of patients with oligometastatic esophageal carcinoma.

Detailed Description: This is a multi-center, open, randomized controlled, phase II clinical study to evaluate the efficiency and safety of chemotherapy and immunotherapy combined with locol radiotharepy in treatment of patients with oligometastatic esophageal carcinoma.For patients required that recurrent or metastatic esophageal cancer, no more than 3 metastatic organs and no more than 5 metastatic lesions. First, all patients receive chemotherapy (the regimen includes paclitaxel and platinum drugs; or cisplatin, pentafluorouracil (5-fluorouracil) ) and other standard first-line chemotherapeutics, combined with Camrelizumab for 4 cycles, and the patients who have not progressed were randomly divided into non-radiotherapy group (control group) and combined radiotherapy group (experimental group) at 1:1 ratio. The experimental group received radiotherapy of the lesion within 8 weeks after the end of chemotherapy and immunotherapy. At least one lesion (both primary and metastatic lesions) was required to be irradiated. Stereotactic body radiotherapy (SBRT, 8Gy/time, 3 -5 times, if other segmentation schemes are used, recommend BED10 \>60Gy) or conventional fractional radiotherapy (parts that are not suitable for SBRT, the total dose is more than 30Gy); the primary lesion should be treated with conventional fractional radiotherapy with a dose of 4000cGy or more;The radiotherapy of the primary lesions and metastases focus is carried out at the same time or sequentially, and immunotherapy shall be started within 8 weeks after the end of all radiotherapy. The control group continued Camrelizumab after 3 weeks of the 4 cycles of chemotherapy combined with immunotherapy. The maintenance immunotherapy of the two groups was: Camrelizumab 200mg Q3W, until PD or toxicity is intolerable or up to 24 months. The endpoint are PFS, OS, ORR and toxicity of the two groups .
