Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Induction chemotherapy plus concurrent chemoradiotherapy has the IIA evidence and the gemcitabine plus cisplatin (GP) regimen has the I evidence in the National Comprehensive Cancer Network (NCCN) guidelines for the treatment of locoregionally advanced nasopharyngeal carcinoma (NPC). More and more evidence shows that immunotherapy combined with chemotherapy has a synergistic effect in treating tumors. GP chemotherapy combined with PD-1 inhibitor has achieved the initial effect in NPC. With the development of radiotherapeutic techniques and equipment as well as advances in treatment modalities, the 5-year overall survival of patients with non-disseminated NPC has exceeded 80%. But there are still about 20-30% of NPC patients who experienced recurrence or metastasis after radical chemoradiotherapy, especially locoregionally advanced patients. In order to improve their survival, we conduct this clinical trial to determine whether GP chemotherapy combined with PD-1 inhibitor as neoadjuvant therapy can improve the failure-free survival rate of locoregionally advanced NPC patients and provide new evidence for their neoadjuvant therapy of them.
