Safety and Efficacy of SBRT in the Reirradiation for Ultra-central Thoracic Malignant Tumors

December 22, 2023 updated by: Peking University Third Hospital
The reirradiation of thoracic tumor is difficult. The possibility of surgery or re course radiotherapy is very small. In the NCCN guideline, only systemic treatment is recommended. However, the effective rate of systemic treatment is low. SBRT has the characteristics of high dose in tumor target area and low dose in surrounding normal tissues. In theory, SBRT is more conducive to the protection of normal tissues and can potentially be used in the salvage treatment of recurrent lesions after radiotherapy. Even so, SBRT is still controversial in the rescue treatment of recurrent lung cancer after radiotherapy, especially for "ultral-central" lesions close to mediastinal structures (such as bronchus, esophagus and large blood vessels), which have a high probability of fatal side effects. However, a few studies on the application of SBRT in the reirradiation for ultral-central lung cancer have shown acceptable safety and efficacy. Generally speaking, there are few studies on SBRT in the treatment of recurrent ultral-central tumor with limited data. The purpose of this study is to further evaluate the efficacy and toxicities of SBRT in the treatment of recurrent ultral-central tumors after radiotherapy.

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.

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

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

N/A

Sampling Method

Non-Probability Sample

Study Population

Patients with recurrent chest "ultral-central" malignant tumors after radiotherapy who received SBRT treatment in our department from 2022 to 2023 were expected to be enrolled.

Description

Inclusion Criteria:

  • Pathological diagnosis is malignant tumor.
  • The location of the target lesion belongs to the ultra-central type of chest.
  • The target lesion had a history of radiotherapy, and the lesion diameter is ≤ 5cm.
  • There is no extensive systemic metastasis or although there is metastasis, the metastasis have been controlled by previous treatment.
  • KPS>70, no serious or uncontrolled underlying diseases, such as severe or uncontrolled hypertension, diabetes, cardiovascular and cerebrovascular diseases and organ dysfunction, and patients are expected to be tolerated by radiotherapy.

Exclusion Criteria:

  • Poor basic pulmonary function or symptom correlation caused by various reasons, unable to lie flat or cooperate with treatment.
  • The general condition is poor, and the expected survival time is less than 3 months.
  • Psychiatric patients or poor compliance, unable to cooperate to complete treatment.
  • For other reasons, the researcher believes that it is not suitable to participate in this trial.

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
Toxcicties
Time Frame: From the beginning of the treatment to 3 years after the treatment.
Adverse events of radiation of normal tissues (Including lung, trachea, bronchus, esophagus, blood vessels, ribs, spinal cord, brachial plexus).
From the beginning of the treatment to 3 years after the treatment.
Local control time
Time Frame: From the beginning of the treatment to 3 years after the treatment.
The time from the date of SBRT to the date of recurrence of the target tumor or the date of last observation.
From the beginning of the treatment to 3 years after the treatment.

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
Overall survival time
Time Frame: From the beginning of the treatment to 3 years after the treatment.
The time from the date of SBRT to the date of death from any cause or the date of last observation.
From the beginning of the treatment to 3 years after the treatment.
Disease progression time
Time Frame: From the beginning of the treatment to 3 years after the treatment.
The time from the date of SBRT to the date of disease progression from any cause or the date of last observation.
From the beginning of the treatment to 3 years after the treatment.
