Terms in these criteria, in plain language(14)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Reproductive potential

Able to have children. For women this usually means from the first period until menopause, unless permanently unable to through surgery; for men, unless permanently sterile. Read who the line is about — participants, women, men, or their partners.

Criteria about it usually ask for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Allogeneic and autologous transplant

Stem cell (bone marrow) transplants. Allogeneic uses cells from a donor; autologous uses your own cells, collected earlier and given back.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

What researchers measure

Primary outcomes

  1. Incidence of Treatment-Related Grade 2 or Higher Acute Adverse Events

    Percentage of participants who experience treatment-related Grade 2 or higher acute adverse events from the start of radiotherapy to 3 months after completion of radiotherapy, assessed according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0 (NCI-CTCAE v5.0).

    Time frame: Up to 3 months

Secondary outcomes

  1. Disease-Free Survival

    Time from the start of radiotherapy to the first documented disease recurrence, distant metastasis, or death from any cause, whichever occurs first.

    Time frame: Up to 3 years

  2. Overall Survival

    Time from the start of radiotherapy to death from any cause.

    Time frame: Up to 3 years

  3. Locoregional Recurrence Rate

    ercentage of participants who develop locoregional recurrence during follow-up. Locoregional recurrence includes recurrence in the tumor bed, mediastinum, pleura, or regional lymph nodes, as assessed by imaging, pathology, or clinical evaluation.

    Time frame: Up to 3 years

  4. Distant Metastasis Rate

    Percentage of participants who develop distant metastasis during follow-up, as assessed by imaging, pathology, or clinical evaluation.

    Time frame: Up to 3 years

  5. All-Cause Mortality Rate

    Percentage of participants who die from any cause during follow-up.

    Time frame: Up to 3 years

  6. Incidence of Treatment-Related Late Adverse Events

    Percentage of participants who experience treatment-related late adverse events occurring 6 months or later after completion of radiotherapy, including pulmonary, cardiac, esophageal, or other late adverse events, assessed according to NCI-CTCAE v5.0.

    Time frame: From 6 months after completion of radiotherapy to 3 years

  7. Total Economic Cost

    Total economic cost per participant during the study period, including direct medical costs, non-medical costs, and indirect costs. Direct medical costs include radiotherapy costs, radiotherapy-related symptomatic treatment costs, and costs for the management of toxic and adverse reactions. Non-medical and indirect costs include transportation costs, accommodation costs, and lost work or companion time costs. Costs will be calculated in Chinese Yuan.

    Time frame: Up to 3 years

  8. Quality of Life Score Assessed by EORTC QLQ-C30

    Quality of life will be assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30). The global health status/quality of life score will be recorded at baseline and predefined follow-up visits. Scores range from 0 to 100, with higher scores indicating better global health status/quality of life.

    Time frame: Up to 3 years

  9. Swallowing Function Score Assessed by the Standardized Swallowing

    Swallowing function will be assessed using the Standardized Swallowing Assessment (SSA). The total SSA score will be recorded at baseline and predefined follow-up visits, with higher scores indicating worse swallowing function.

    Time frame: Up to 3 years

Other outcomes

  1. Odds Ratios for Cardiac-Related Disease Occurrence According to Predefined Cardiac and Coronary Artery Dose Parameters

    Odds ratios for cardiac-related disease occurrence per 1-Gy increase in predefined cardiac and coronary artery dose parameters will be estimated using logistic regression. Predefined dose parameters will include mean heart dose and coronary artery substructure dose parameters, measured in Gray (Gy) from the radiotherapy treatment plan. Cardiac-related disease occurrence will be defined as the occurrence of clinically diagnosed cardiac disease or cardiac adverse events during follow-up, assessed by clinical cardiac evaluation and NCI-CTCAE v5.0. Cardiac-related diseases or adverse events may include coronary artery disease, myocardial ischemia or infarction, arrhythmia, heart failure, pericardial disease, or other clinically diagnosed cardiac events.

    Time frame: From baseline to up to 3 years after radiotherapy
