Purpose:
We aimed to evaluate therapeutic results of radiotherapy for gastric mucosa-associated lymphoid tissue (MALT) lymphomas.
Patients And Methods:
We reviewed retrospectively the records of 11 patients presenting with gastric MALT lymphoma treated between 1993 and 2014. Patients with low-grade lymphoma in failure after helicobacter eradication had exclusive gastric external radiotherapy. Chemotherapy followed by radiotherapy were indicated in case of high grade lymphoma. Radiotherapy doses range between 30 and 40Gy (2Gy per fraction, five fractions per week).
Results:
All tumours were IE stage. Seven patients with low-grade lymphoma had radiotherapy. Four patients with high-grade lymphoma received chemotherapy then radiotherapy. Ten patients are in complete remission after treatment achievement. Five and 10 years disease-free survival are 100%. No severe toxicity was seen.
Conclusion:
Eradication of Helicobacter pylori is the mainstay of treatment of gastric MALT. External irradiation is an effective and well-tolerated treatment modality in case of resistance to helicobacter eradication.

Lymphoid Cells and Tissues
Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...

Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
