Clinical trials

This study plans to enroll patients with histologically or cytologically confirmed locally recurrent nasopharyngeal carcinoma. After signing informed consent, eligible subjects will receive three cycles of standard-dose becotatug vedotin combined with a PD-1 inhibitor. Following treatment, imaging assessment and surgical evaluation will be performed. Subjects deemed operable will undergo endoscopic nasal surgery, after which the MDT (multidisciplinary team) will discuss and determine a maintenance treatment plan. For subjects who are not eligible for surgery, the MDT will decide on either maintenance therapy or a switch to an alternative treatment regimen.

The goal of this clinical trial is to learn about the induction chemotherapy efficacy in olfactory neuroblastoma. The main question it aims to answer is: wether olfactory neuroblastoma patients with different pathology subtypes apply to different induction chemotherapy schemes. Participants will be treated with different chemotherapy schemes, to evaluate the tumor remission rate and long term survival.
