Simultaneous Integrated Boost vs. Routine IMRT in Limited-stage Small-cell Lung Cancer

January 27, 2021 updated by: Zongmei Zhou, Cancer Institute and Hospital, Chinese Academy of Medical Sciences

A Randomized Phase III Study of Comparison Between Simultaneous Integrated Boost (SIB) Intensity-modulated Radiation Therapy (IMRT) Versus Routine IMRT/VMAT in LD-SCLC

Thoracic radiotherapy concurrent with chemotherapy stands for the standard regime for limited staged small cell lung cancer. Involved node radiation（INF） replaced elective node irradiation（ENI） as the more popular since several trails compared the two regimes. simultaneous integrated boost IMRT becomes mature with advancing in IMRT and VMAT. The investigator hypothesis that SIB-IMRT can confine the dose for organs at risk to reduce the toxicities compared with routine IMRT in limited disease small-cell lung cancer.

Study Overview

Indicates the current recruitment status or the expanded access status.

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.

Detailed Description

All patients recruited divided into two arms：SIB-IMRT or routine IMRT，in the routine arm，the prescription dose was 60Gy/2Gy/30f，and in the SIB arm ，60Gy was given to the field of the tumor and metastatic lymph nodes，50Gy was given to CR lesion and high-risk prevention. The physical advantages of SIB-IMRT are to reduce the radiation dose of organs that are at risk in the lungs, esophagus, and heart ensuring the adequate dose for tumor area at the same time. The investigators are carrying out this trial to compare the efficacy, safety, side effects, and type of failure of the two radiotherapy techniques, which will provide a new choice and reliable basis for the future dose-segmentation study of limited-stage small-cell lung cancer.

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.

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.

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.
