About this study

Official title: Study on the Safety and Efficacy of 3D-printed Template Assisted Ct-guided RISI in the Treatment of Recurrent Metastatic Squamous Cell Carcinoma of Thoracic Inlet Lymph Nodes After Radiotherapy: a Multi-center Prospective Cohort Study

The malignant tumor at the thoracic entrance is difficult to be surgically removed, and radiotherapy or radiotherapy based comprehensive treatment is often chosen at the initial diagnosis. However, for patients with recurrence after radiotherapy, there is basically no ideal local treatment.The Radioactive i-125 Seed Implantation (RISI) therapy is characterized by high dose within the tumor target area and low dose to surrounding normal tissues, and its radiation dose rate is low, which theoretically benefits the protection of normal tissues and is more suitable for the salvage treatment of recurrent lesions after radiotherapy.3 d printing template technology is through the advance of the preoperative plan design and optimization, to achieve better avoid endanger organs, template of individualized and human body surface after laminating, registration accuracy, its guide pillar to precise control the direction of the needle, the present data show that in the template with CT guided by solid tumors as well had significantly higher accuracy, as the actual target dose of basic postoperative can reach the design request of the preoperative planning, so the application of 3 d printing template helps to further improve the operation efficiency and safety, also has potential promotion effect to curative effect.

The purpose of this study is: (1) Observe the efficacy, toxicity and side effects of 3d-printed template assisted ct-guided RISI in the treatment of recurrent metastatic squamous cell carcinoma of thoracic inlet lymph node after radiotherapy, and evaluate its safety and effectiveness; (2) to explore the relationship between the efficacy, toxicity and side effects of relapsed metastatic squamous cell carcinoma of thoracic inlet lymph node after radiotherapy with different RISI doses;(3)the related influencing factors affecting the effect/toxicity of RISI in the treatment of relapsed lymph node metastatic squamous cell carcinoma at the thoracic inlet after radiotherapy were analyzed.

Read the detailed description

This is a non-randomized, prospective, single-arm, cohort study.Patients meeting the inclusion criteria were enrolled successively in the order of admission and treatment.In this study, the dose interval was set as 110-130gy, and a total of 30 patients were expected to be enrolled. The prescription dose was planned to be grouped into 15 patients of 110-120gy and 120-130gy respectively. The specific situation was subject to the actual postoperative verification dose.

What is being measured

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

  1. Local tumor control rate

    The time from the date of seeds implantation to the date of recurrence of the implanted tumor or the date of last observation.

    Measured: 3 years

  2. Incidence of adverse events

    The adverse events are evaluated by the common terminology criteria for adverse events (CTCAE). The rate of each adverse event will be measured.

    Measured: 3 years

Secondary outcomes (2)
  1. Overall survival time

    The time from the date of seeds implantation to the date of death from any cause or the date of last observation.

    Measured: 3 years

  2. progression-free survival

    The time between the beginning of treatment and the progression of the disease or the occurrence of death for any reason.

    Measured: 3 years

Questions about this trial

What is this clinical trial studying?

A study testing 3D-printing Template-assisted CT-guided I-125 Seed Implantation in people with Brachytherapy and Squamous Cell Carcinomas, run by Peking University Third Hospital 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 6 inclusion and 6 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: status not confirmed, as of the sponsor's last update on 27 Dec 2023. 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?

Results are not available in the source record.

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

Contact Zhe Ji, M.D. (008618710002823, aschoff@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Local tumor control rate (time frame: 3 years). The study lists 2 primary outcomes in all. 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 27 Dec 2023.
