30Gy Versus 40Gy Involved-field Radiotherapy for Localized Diffuse Large B Cell Lymphoma Achieving CR After Chemotherapy

July 1, 2010 updated by: Cancer Institute and Hospital, Chinese Academy of Medical Sciences

Phase 3 Study of 30Gy Versus 40Gy Involved-field Radiotherapy in Localized Diffuse Large B Cell Lymphoma Achieving CR After Chemotherapy

The purpose of this study is to determine whether 30Gy Involved-field Radiotherapy (IFRT) is as effective as 40Gy in the treatment of localized Diffused Large B cell Lymphoma (DLBCL) when completing CR after chemotherapy.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

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

The best proper doses of IFRT in combined modality treatments (CMT) for localized DLBCL is still undetermined. Existing treatment guidelines recommend 40Gy or above as the standard treatment dosage. However, there were large-scaled clinical trials implying smaller doses such as 30Gy may be equivalent effective. Lowering radiation doses can decrease treatment toxicities and radiotherapy-induced diseases, which has been conformed by HD13 study for Hodgkin's Lymphoma. It may even retain the truth when modern era radiation techniques are involved and especially in patients achieving CR after chemotherapy. A comprehensive, prospective dose-comparing study is needed.

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

15 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

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.
