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

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Age ≥ 18 years old
  • Pathologically confirmed as ATC, thyroid cancer containing ATC components, PDTC (in accordance with Turin criteria), or other thyroid cancers with poorly differentiated components, and the MDT considers the biological behavior similar to PDTC.
  • Evaluated by the MDT and proposed to receive external beam radiotherapy, including postoperative R0/R1, R2 gross residual, inoperable local lesion, and local recurrence.
  • ECOG performance status 0-2
  • expected survival ≥ 3 months
  • major organ functions can meet the requirements for radiotherapy and the proposed systemic treatment.
  • The subject voluntarily participates in the study and signs a written informed consent form, willing to follow up according to the protocol and fill in the quality of life scale.

Exclusion Criteria:

  • Has received radiotherapy to the head and neck or upper mediastinum region in the past, and the target area of this study overlaps significantly with it, and the normal tissue limit cannot be met.
  • Has severe uncontrolled infections, active bleeding, unaddressed airway crises, severe dysfunction of the heart, lungs, liver, kidneys or other diseases that cannot be safely treated with radiotherapy.
  • Pregnant or lactating women; women of childbearing age who do not agree to take effective contraceptive measures.
  • Has other active malignant tumors within 5 years or simultaneously (excluding cured localized tumors such as skin basal cell carcinoma, skin squamous cell carcinoma, superficial bladder cancer, prostate carcinoma in situ, cervical carcinoma in situ, breast carcinoma in situ, etc.)
  • Cannot complete radiotherapy fixation, simulation positioning or follow-up imaging assessment.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Selective coverage radiotherapy
Radiation: Selective coverage radiotherapy
  1. GTV or GTV tb 66-70Gy/33-35Fx
  2. High-risk CTV 60Gy: Expand the GTV/GTVtb by 10 mm and adjust according to the anatomical barriers, pre-treatment area were involved if received systemic treatment before radiotherapy；The lymphatic drainage areas where the positive lymph nodes are located, can also be regarded as high-risk CTVs according to MDT decision.
Active Comparator: comprehensive coverage radiotherapy
Radiation: comprehensive coverage radiotherapy
  1. GTV or GTV tb 66-70Gy/33-35Fx
  2. CTV: Expand the GTV/GTVtb by 10 mm and adjust according to the anatomical barriers, pre-treatment area were involved if received systemic treatment before radiotherapy（60 Gy）；prophylactic irradiation was performed on the bilateral neck II-VI regions and upper mediastinum regions based on the extent of lymph node invasion, and the dose was determined according to the risk stratification（54-60Gy）.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Locoregional control rate，LRC
Time Frame: 12 months
The time from the randomization date to the first occurrence of locoregional progression/recurrence. Locoregional regions include the primary thyroid lesion or the postoperative tumor bed, the central region/upper mediastinal related regions, the cervical lymph node region, the retropharyngeal lymph nodes, and the cervical soft tissue contiguous with the original lesion. 12-month LRC is defined as 1 minus the cumulative incidence of locoregional progression over 12 months.
12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Progression Free Survival，PFS
Time Frame: 12 months
From the date of randomization to the date of the first recording of tumor PD (evaluated according to the RECIST 1.1) or the date of death due to any cause, whichever comes earlier. PD includes local regional recurrence/progression and distant metastasis.
12 months
Overall Survival, OS
Time Frame: 12 months
The time from randomization to death due to any cause.
12 months
Disease Control Rate，DCR
Time Frame: up to 12 months
Defined as the proportion of patients with a complete response, partial response and stable Disease to radiotherapy according to Response Evaluation Criteria in Solid Tumors (RECIST). Applicable to those with measurable lesions.
up to 12 months
Adverse Events
Time Frame: 12 months
All radiotherapy-related adverse events will be documented
12 months
Quality of Life (QoL) by EORTC QLQ-H&N35 questionnaire.
Time Frame: 12 months
Changes in QoL of participants from baseline to up to 12 months after the radiotherapy. Use EORTC QLQ-H&N35 questionnaire.
