Non-Hodgkin's lymphomas presenting with gastrointestinal involvement

Area of Science:

• Oncology
• Gastroenterology
• Pathology

Background:

• Non-Hodgkin's lymphoma (NHL) can involve the gastrointestinal tract, presenting unique diagnostic and therapeutic challenges.
• Accurate pathological classification and staging are crucial for determining prognosis and treatment strategies in GI NHL.

Purpose of the Study:

• To analyze the clinical characteristics, treatment, and outcomes of patients with gastrointestinal non-Hodgkin's lymphoma (GI NHL).
• To identify prognostic factors influencing survival in patients with GI NHL.

Main Methods:

• Retrospective review of 33 patients diagnosed with GI NHL between 1978 and 1983.
• Pathological classification using the Kiel classification; staging according to disease extent.
• Analysis of treatment modalities (surgery, chemotherapy, radiotherapy) and survival data.

Main Results:

• The most common histological type was lymphoplasmacytoid immunocytoma (11 patients).
• Stomach (23 patients) and ileocecal region (6 patients) were the most frequent sites.
• 20 out of 33 patients presented with early-stage (I and II) disease.
• Patients with early-stage disease and complete tumor resection achieved long-term survival (mean 32.9+ months).
• Patients with advanced disease (stage III/IV) or lymphoblastic lymphoma had survival probabilities under 12 months.

Conclusions:

• Surgical resection combined with adjuvant therapy offers favorable long-term outcomes for early-stage GI NHL.
• Advanced stage and specific histological subtypes (e.g., lymphoblastic lymphoma) are associated with poorer prognoses.
• Multimodality treatment tailored to disease stage and histology is essential for managing GI NHL.
