Burkitt's lymphoma--a study of 50 consecutive cases

Area of Science:

• Oncology
• Hematology
• Epidemiology

Background:

• Burkitt's lymphoma is a highly aggressive non-Hodgkin's lymphoma.
• Understanding its epidemiological patterns is crucial for diagnosis and treatment.
• Pakistan is considered non-endemic for Burkitt's lymphoma.

Purpose of the Study:

• To present a retrospective analysis of Burkitt's lymphoma cases in Pakistan.
• To determine the relative frequency and clinical characteristics of Burkitt's lymphoma.
• To compare findings with global patterns.

Main Methods:

• Retrospective study design.
• Data collected over a 7-year period.
• Analysis of patient demographics, clinical presentation, disease stage, and survival.

Main Results:

• Relative frequency of Burkitt's lymphoma was 6.35% among non-Hodgkin's lymphomas.
• Male predominance (M:F 2.3:1) observed.
• Majority of cases occurred in the pediatric age group.
• Abdominal presentation (intestinal, retroperitoneal) was most common (42%), with rare jaw tumors (4%).
• Primary nodal disease in 36%, bone marrow infiltration in 54%.
• Advanced stage at diagnosis in 54% of cases.
• Poor survival observed despite treatment.

Conclusions:

• Burkitt's lymphoma occurs with higher frequency in Pakistan than in comparable non-endemic countries.
• The 'American mode' of presentation (abdominal) is more prevalent than the 'African mode' (jaw tumor).
• Advanced disease stage and bone marrow infiltration are common at diagnosis, contributing to poor outcomes.
