Chemoimmunotherapy With or Without SBRT Before Surgery for Locally Advanced Oral and Oropharyngeal Cancer

Официальное название

Neoadjuvant Chemoimmunotherapy With or Without SBRT Followed by Surgery for Locoregionally Advanced Squamous Cell Carcinoma of the Oral Cavity and Oropharynx: A Phase II Randomized Trial

Обзор

In this study, participants will be randomly assigned to either the experimental group or the control group. The experimental group will first receive SBRT (6Gy\*3 fractions) to treat the primary tumor and metastatic lymph nodes. This will be followed by a combination of Toripalimab, Docetaxel, and Cisplatin for three cycles, every three weeks. The control group will receive the same combination of Toripalimab, Docetaxel, and Cisplatin for three cycles, every three weeks, but without SBRT. After the final round of chemotherapy, all participants will have imaging scans and, three weeks later, undergo surgery. After surgery, they may also receive additional radiotherapy with or without chemotherapy. Patients can also choose whether to continue treatment with Toripalimab after surgery.

Подробное описание

Participants will be randomly assigned to the experimental group and the control group. The experimental group will first receive SBRT (Stereotactic Body Radiotherapy) for the primary tumor and positive lymph nodes (prescribed dose: 6 Gy × 3 fractions, once every other day). One to two weeks after SBRT, they will receive 240 mg of Toripalimab + 75 mg/m² of Docetaxel + 75 mg/m² of Cisplatin, administered every 3 weeks for 3 cycles. The control group will receive 240 mg of Toripalimab + 75 mg/m² of Docetaxel + 75 mg/m² of Cisplatin, administered every 3 weeks for 3 cycles. Both groups will undergo imaging assessment 2 weeks after the final chemotherapy cycle. Three weeks after the last chemotherapy cycle, participants will receive curative surgery. Postoperative adjuvant radiotherapy ± chemotherapy will be administered according to preoperative staging and postoperative pathological characteristics. Patients may also choose to continue maintenance treatment with Toripalimab after surgery.
