Overview

To evaluate whether individualized elective neck irradiation for nasopharyngeal carcinoma based on the vertebral level of metastatic lymph nodes can reduce the incidence of radiation-related adverse effects and improve patients' quality of life,without reducing survival.

Description

A multicenter phase III noninferiority randomized trial (NCT02642107) showed that upper-neck irradiation at the uninvolved neck resulted in comparable regional control and survival rate to standard whole-neck irradiation in NPC, reduced late toxicity of hypothyroidism, dysphagia, and neck tissue damage, and improved quality of life, including fatigue and swallowing.

However, the vertical range of the upper neck is extensive, necessitating further reduction in the scope of prophylactic irradiation. By integrating MRI and PET-CT to accurately assess metastatic lymph nodes and their corresponding vertebral levels, the investigators identified a pattern of sequential lymph node metastasis descending along the vertebral body in the vertical direction. Further correlative analysis revealed that nodal metastasis at any one of the vertebral levels strongly and positively correlated with metastasis at two adjacent vertebral levels, including one level above and one below.

Considering this, the investigators propose the following scientific hypothesis: individualized elective neck irradiation for nasopharyngeal carcinoma based on the vertebral level of metastatic lymph nodes can reduce the incidence of radiation-related adverse effects and improve patients' quality of life, without reducing survival. The investigators thus conduct a multicenter randomized phase 3 trial to verify their hypothesis.

Eligibility

Exclusion Criteria:

  • The exclusion criteria include: previous chemotherapy treatment, surgery (except diagnostic) or radiotherapy to the neck or nasopharyngeal regions; previous malignancy; lactation or pregnancy; or severe coexisting illness.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
