Recurrent Nasopharyngeal Carcinoma

This phase II trial tests the addition of BMS-986016 (relatlimab) to the usual immunotherapy after initial treatment for nasopharyngeal cancer that has come back after a period of improvement (recurrent) or that has spread from where it first started (primary site) to other places in the body (metastatic). Relatlimab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. The usual approach of treatment is initial treatment with chemotherapy such as the combination of cisplatin (or carboplatin) and gemcitabine, along with immunotherapy such as nivolumab. After the initial treatment is finished, patients may continue to receive additional immunotherapy. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of tumor cells. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Gemcitabine is a chemotherapy drug that blocks the cells from making deoxyribonucleic acid (DNA) and may kill cancer cells. Giving BMS-986016 in addition to the usual immunotherapy after initial treatment may extend the time without the tumor cells growing or spreading longer than the usual approach in patients with recurrent or metastatic nasopharyngeal cancer.

This is a multicenter, randomized controlled, phase III clinical trial. The purpose of this study is to evaluate the efficacy and adverse effect of PD-1 antibody with chemoradiotherapy versus chemoradiotherapy alone in recurrent nasopharyngeal carcinoma patients.

This study aims at exploring whether plasma radiofrequency ablation at low temperature is associated with better survival outcome in localized recurrent nasopharyngeal carcinoma by conducting a randomized controlled trial of plasma radiofrequency ablation at low temperature versus electrocautery block resection at high frequency for localized recurrent nasopharyngeal carcinoma. If the hypothesis is confirmed, it is expected to provide a convenient choice for the surgical treatment of localized recurrent nasopharyngeal carcinoma.

This clinical trial aims to determine whether Natural Killer (NK) cell therapy administered in combination with concurrent chemoradiotherapy (CRT) can reduce recurrence in patients with advanced nasopharyngeal cancer (NPC), and to identify the highest safe and tolerable dose of allogeneic NK cells. Allogeneic NK cells, derived from healthy donors, have demonstrated good tolerability in cancer patients. The primary research questions are: 1. What is the maximum tolerated dose (MTD) of allogeneic NK cells when administered with CRT in NPC patients? 2. Can the addition of allogeneic NK cells to standard CRT reduce the proportion of NPC patients with detectable plasma EBV-DNA from 30% to 10%? Phase 1: Participants will receive one of five escalating doses of allogeneic NK cells with CRT to determine the MTD. Phase 2: Participants will receive the established MTD NK dose together with CRT. Participants will undergo regular safety monitoring, side-effect assessment, measurement of plasma EBV-DNA levels, and surveillance for disease recurrence.

The above studies show that most of the supportive evidence for the reduction of toxicity and improvement of efficacy of proton therapy for recurrent Nasopharyngeal carcinoma(NPC) comes from various observational and retrospective studies, lacking high-level evidence-based medical evidence. The conduct of this study will explore the safety and efficacy of intensity-modulated proton radiotherapy for recurrent NPC and provide more high-quality evidence-based medical evidence for proton therapy of recurrent cancer.

The purpose of this study is to compare chemotherapy plus immunotherapy with immunochemotherapy combined subsequent locoregional radiotherapy in recurrent nasopharyngeal carcinoma (NPC), in order to confirm the value of immunotherapy and chemotherapy in recurrent NPC patients.

Adjuvant Therapy Versus Endoscopic Surgery Alone in Early-stage Recurrent Nasopharyngeal Carcinoma: A Multicenter Randomized Controlled Trial

A multicenter randomized controlled study of surgery combined with neoadjuvant and adjuvant therapy for locally advanced recurrent nasopharyngeal carcinoma in comparison to surgery combined with adjuvant therapy

This is a phase 3, multicentre, randomised controlled trial to study the effectiveness and toxicity of PD-1 antibody Toripalimab combined with concurrent cisplatin chemoradiotherapy versus cisplatin concurrent chemoradiotherapy alone in treating patients with locoregionally recurrent nasopharyngeal carcinoma.

This study is a multicenter RCT to compare 3-year overall survival(OS) rate, progression free survival(PFS),local progression free survival(LPFS),regional progression free survival(RPFS),distant metastasis free survival(DMFS), and toxicities of endonasal endoscopic surgery versus IMRT.
