Reducing High Risk Primary Tumor Clinical Target Volumes (CTVp1) in Non-metastatic Nasopharyngeal Carcinoma Treated With Intensity-modulated Radiotherapy(IMRT): A Phase 3, Multicentre, Randomised Controlled Trial(CTVp1-NPC)

To evaluate the long-term local control, survival rate, acute and late radiation related toxicities, quality of life after reducing high risk primary tumor clinical target volumes (CTVp1) in non-metastatic nasopharyngeal carcinoma treated with IMRT.

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

This phase 3, multicenter,randomized controlled clinical trial recruits patients with newly-diagnosed non-metastatic nasopharyngeal carcinoma patients treated with IMRT. The intervention is delineating high risk primary tumor clinical target volumes (CTVp1) as GTV+5mm or GTV+5mm+whole nasopharynx. The objective is to compare the long-term local control, survival rate, acute and late radiation related toxicities between the two groups.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
