Diffuse histiocytic lymphoma involving the gastrointestinal tract
Cancer
|May 1, 1978
Summary
Most patients with diffuse histiocytic lymphoma of the gastrointestinal tract present with widespread disease, requiring systemic therapy. Current treatments show limited success, highlighting the need for improved chemotherapy and complication prevention strategies.
Area of Science:
- Oncology
- Gastroenterology
- Hematology
Background:
- Diffuse histiocytic lymphoma (DHL) can involve the gastrointestinal tract.
- Accurate staging is crucial for determining appropriate treatment strategies.
Purpose of the Study:
- To summarize the staging and treatment outcomes for 18 patients with gastrointestinal DHL.
- To identify factors contributing to treatment failure and complications.
Main Methods:
- Retrospective review of 18 patients with gastrointestinal DHL.
- Rigorous staging procedures were employed.
- Treatment modalities included chemotherapy, surgical resection, and radiation therapy.
Main Results:
- 72% of patients presented with Stage IV (widespread) disease.
- Complete remission was achieved in only 28% of patients.
- Treatment failures were attributed to tumor drug resistance (46%) and complications like hemorrhage or perforation (38%).
Conclusions:
- Localized gastrointestinal lymphoma is rare; most cases require systemic therapy.
- Current treatment regimens have limited efficacy, necessitating the development of more active chemotherapeutic approaches.
- Preventing complications such as bowel perforation and hemorrhage is critical, potentially through combined surgical and systemic chemotherapy approaches.
