Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Treatment: Other - Involved Field Radiotherapy

Experimental: 1 -


Treatment: Other: Involved Field Radiotherapy
The prescribed dose will be 30 Gy in 15-20 fractions, unless the orbit is to be treated, in which case the dose will be 24 Gy in 1.5 to 2 Gy fractions.

Daily fractions of 1.5-2.0 Gy will be employed. Treatment will be given 5 days per week with the planned duration of treatment not exceeding 28 days.

Eligibility
Key inclusion criteria
* Patients of at least 18 years old with histologically documented non-gastric marginal zone lymphoma.
* Disease limited to stages I and II after adequate staging (see Appendix II), patients with stage IV with extranodal disease confined to paired organs (e.g. salivary glands) and including any local extension of this disease into adjacent tissues. Patients with involved lymph nodes on the same side of the diaphragm in addition to paired organ involvement are also eligible, provided all involved tumour sites, nodal and extranodal, can be irradiated to 30 Gy within the tolerance of the relevant normal tissues. If paired organ involvement was regarded as a single extranodal site (rather than 2 separate sites and hence stage IV), eligible patients would then be regarded as having stage IE or IIE disease. Patients with wider dissemination (bone marrow, liver etc) are ineligible.
* Anticipated life expectancy > 2 years
* Given written informed consent
* Been assessed by a radiation oncologist
* Agree to undergo breath testing for H. pylori and/or oesophagogastroduodenoscopy to exclude active infection with helicobacter pylori
* Must be available for long-term follow up
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
* Splenic marginal zone lymphoma
* Received previous locoregional radiotherapy
* A medical contraindication to radiotherapy
* Any previous or concurrent malignancy other than curatively treated non-melanoma skin cancer, level 1 malignant melanoma, or in situ cervical cancer, unless disease and treatment-free for 5 years
* Such extensive involvement of the thorax that treatment with radiotherapy alone would be hazardous because of excessive lung irradiation, even if a shrinking field technique were employed
* Suspected or confirmed pregnancy
* Transformation to large cell lymphoma or other aggressive histology
* Disease that is widely disseminated (bone marrow, liver etc)

Summary
Brief summary
This prospective study will test the following hypotheses in patients with stage I-II low grade marginal zone (MZ) lymphoma:

* Involved Field Radiotherapy will produce a complete response rate of \> 90%
* Radiotherapy will be associated with a locoregional progression of \< 20% after 10 years
* Death from MZ lymphoma will occur in \< 40% of patients within 10 years of radiotherapy

This study secondary objectives are:

* To collect information on the prevalence of H. pylori in non-gastric MALT lymphoma
* To estimate rates of acute and late toxicity of radiotherapy
