Radiation Therapy Alone for the Treatment of Stage 1 and 2 Mucosa-Associated Lymphoid Tissue (MALT) Lymphoma

February 25, 2022 updated by: M.D. Anderson Cancer Center

Radiation Therapy Alone for Stage 1 and 2 MALT (Mucosa-Associated Lymphoid Tissue) Lymphoma

This trial studies the side effects of radiation therapy used alone, and if it can achieve a high cure rate in the treatment of patients with MALT lymphoma. Radiation therapy uses high energy sources to kill cancer cells and shrink tumors. This treatment may improve the patient's lymphoma.

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

PRIMARY OBJECTIVE:

I. To determine the efficacy and toxicity of radiation therapy alone in treating stage 1 and 2 MALT lymphoma for newly diagnosed patients and for the patients who failed other treatment modalities.

OUTLINE:

Patients undergo radiation therapy once daily (QD) 5 times weekly over 3.5-5 weeks.

After completion of study treatment, patients are followed up at 6-8 weeks, and then every 3-4 months for year 1, every 4-6 months for year 2, every 6 months for years 3 and 4, and once yearly thereafter.

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

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Patients with newly diagnosed stage 1 and 2 MALT lymphoma are eligible for this study
  • Patients with Helicobacter (H.) pylori positive gastric MALT lymphoma are recommended to have treatments with antibiotics prior to enrollment to this protocol
  • Patients who failed other treatment modalities (e.g. chemotherapy, antibiotics therapy etc) are also eligible as far as they never had stage 3 or 4 disease during the course of the disease or disease progression to the opposite side of the diaphragm (as the time course of the response to antibiotic therapy can be very variable among patients, sometimes requiring more than one year for complete response, failure to antibiotic therapy can be very variable among patients, sometimes requiring more than one year for complete response, failure to antibiotic treatment will be defined as no response or progression of the disease documented by endoscopy and biopsy)
  • Patients who have had stage 4 diseases due to bilateral parotid gland or ocular/ocular adnexal involvement or due to multiple sites within Waldeyer's ring will still be eligible

Exclusion Criteria:

  • Patients who had previous radiation dose to the site of the current primary disease which would lead to violation of known radiation tolerance limit of that particular site if treated again
  • Patients with MALT lymphoma of the skin whose lesions are separated by more than 5 cm will be ineligible
  • Previous or concurrent malignancy in any form would not be an exclusion criterion. However, patients who receive chemotherapy for concurrent malignancy will be excluded from statistical analysis
  • Low blood cell counts would not be exclusion criteria as far as the patient is willing to accept supportive measures such as transfusions, filgrastim and epoetin

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
Relapse-free Survival (RFS)
Time Frame: Through study completion, up to 10 years
RFS was defined as the time in months from the date of study entry until the last follow-up or death, with all deaths censored. Kaplan-Meier curves were estimated for the survival distributions.
Through study completion, up to 10 years

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
Median Progression Free Survival (PFS)
Time Frame: 17.5 years
PFS is defined as the time from randomization to progression or death. Kaplan-Meier curves were estimated for the survival distributions.
17.5 years
Progression Free Survival (PFS) at 10 Years
Time Frame: Through study completion, up to 10 years
PFS events is the time in months and defined as any lymphoma relapse ( lymphoma that comes back after successful treatment and a period of remission) or death from any cause. Kaplan-Meier curves were estimated for the survival distributions.
Through study completion, up to 10 years
10 Year Overall Survival (OS)
Time Frame: Through study completion, up to 10 years
Overall Survival is the time in months from start of study treatment to date of death due to any cause. Overall survival rates are estimated by the Kaplan-Meier method.
Through study completion, up to 10 years
