About this study

Official title: The Second Affiliated Hospital of Hainan Medical University

Aim to observe the application of MR-Linac for precision radiotherapy of tumours, analyse its therapeutic effect, toxic and side effects,Characteristics of dosimetric parameters etc.

Read the detailed description

Primary endpoint:

  • Overall response rate (ORR) : It refers to the proportion of patients whose tumor volume reduction reaches the pre-specified value and can maintain the minimum time requirement, which is a Complete Response (CR) and a partial response (PR). Partial Response) sum of the proportions.

Secondary points:

  • Progression-free Survival (PFS) : the time from the start of treatment until objective tumor Progression or all-cause death of the patient.
  • Disease Control Rate (DCR) : The percentage of patients whose cancer shrinks or remains stable over time.
  • Overall Survival (OS) : the time from the start of treatment to all-cause death.
  • Incidence of adverse reactions: toxicity according to Common Toxicity Criteria for Adverse Events (CTCAE).
  • Quality of life: The EORTC Quality of Life measure -QLQ-C30-(V3.0) was used, and the higher the score, the higher the quality of life.
  • Dosimetric parameters: include gross target volume(GTV), clinical target volume(CTV),internal target volume(ITV),planning target volume(PTV),γ-passing rate,and limited dose of organs at risk (including average dose, maximum dose, etc.)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. overall response rate

    The proportion of patients whose tumor volume reduction reached the predetermined value and maintained the minimum time limit requirement was the sum of CR (Complete Response) and PR (Partial Response) proportions.

    Measured: 3months, 6months,12months,24months,36months,60months

Secondary outcomes (8)
  1. Progression-Free Survival

    The time from the start of treatment until objective tumor Progression or patient all-cause death

    Measured: 3months, 6months,12months,24months,36months,60months

  2. Disease Control Rate

    The percentage of patients whose cancer shrinks or remains stable over time

    Measured: 3months, 6months,12months,24months,36months,60months

  3. Overall survival

    Overall survival of participating patients will be obtained from the hospital information systems

    Measured: 3months, 6months,12months,24months,36months,60months

  4. Incidence of adverse reactions

    Disease-specific toxicity is obtained from the hospital information system. Toxicities are reported according to the Common Terminology Criteria for Adverse Events (CTCAE) dictionary

    Measured: 3months, 6months,12months,24months

  5. Patient reported Health related quality of life (HRQoL)

    Patient reported health related quality of life is captured through a questionnaire the Generic European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30. It is a core scale applicable to all cancer patients. It contains a total of 30 items, items 1 to 28 are divided into 4 grades and scored 1 to 4 points, items 29 and 30 are divided into 7 grades and scored 1 to 7 points. The 30 entries are divided into 15 domains, including 5 functional domains (i.e., somatic, role, cognitive, emotional, and social), 3 symptom domains (i.e., fatigue, pain, nausea, and vomiting), 1 quality of life domain, and 6 single entries/domains. A high score on functional or global health status scale represents a high/healthy level of functioning.

    Measured: 3months,6months,12months,24months

  6. Dosimetric parameters:dose of target volume(TV)

    Dose of target volume(TV)includes gross target volume(GTV),clinical target volume(CTV),internal target volume(ITV) and planning target volume(PTV),Measured by cGy.

    Measured: During Radiotherapy

  7. Dosimetric parameters:OAR

    Limited dose of organ at risk(OAR) ,includes mean dose(Dmean), maximum dose(Dmax)and minimum dose(Dmin),Measured by cGy.

    Volume dose limitation,Measured by percent(%),for example, lung V20≤30%.

    Measured: During Radiotherapy

  8. Dosimetric parameters:γ passing rate

    The gamma passing rate evaluates the coincidence between the calculated and measured dose distributions by utilizing the percent dose difference (DD) and distance to agreement.

    Measured: During Radiotherapy

Questions about this trial

What is this clinical trial studying?

An observational study of Overall Response Rate and Oncology, run by The Second Affiliated Hospital of Hainan Medical University at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 13 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact junnv xu, doctor (18208946196, xujunnv@sina.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

overall response rate (time frame: 3months, 6months,12months,24months,36months,60months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Feb 2025.
