Comparable Study of Different Thoracic Radiotherapy Regimens for Extensive Stage Small Cell Lung Cancer

April 2, 2019 updated by: Luhua Wang, Cancer Institute and Hospital, Chinese Academy of Medical Sciences

Randomized Phase III Study Comparing Different Thoracic Radiotherapy Regimens in Patients With Extensive Stage Small Cell Lung Cancer Who Respond to Chemotherapy

Most patients with extensive stage small-cell lung cancer (ES-SCLC) who undergo chemotherapy, and prophylactic cranial irradiation, have persistent intrathoracic disease. A Dutch study recently proved that thoracic radiotherapy(TRT), using 30 Gy in 10 fractions of 3 Gy, could improve 2-year overall survival(OS) of this patient group compared with non-TRT group. But intrathoracic progression was still high, either with or without progression elsewhere, occurring in 43.7% in the TRT group. The ideal TRT regimen for ES-SCLC is undefined. Maybe higher dose can provide better local control(LC) and overall survival. In this study, the investigators propose to give an increased dose of TRT to determine whether higher dose will improve 2-year OS, LC and progression-free survival.

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

This is a multicenter, prospective, randomised phase III study. For patients with ES-SCLC who respond to chemotherapy after four to six cycles of standard chemotherapy (platinum etoposide), 45Gy/15F of thoracic radiotherapy will be used in experimental arm, while 30Gy/10F of thoracic radiotherapy will be used in the control arm. Both survival and toxicity of the two arms will be observed and compared.

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.

Ages Eligible for Study

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers
