Summary
Malignant lymphoma patterns in Oman differ from Western and Eastern data. This study details the epidemiology of Hodgkin's disease and non-Hodgkin's lymphomas in Omani patients.
Area of Science:
- Oncology
- Epidemiology
- Pathology
Background:
- Malignant lymphoma (ML) epidemiology in the Middle East is poorly understood.
- This study addresses a gap in the documented patterns of ML in the region.
Purpose of the Study:
- To describe the epidemiological pattern of malignant lymphoma in native Omani patients.
- To compare Omani ML patterns with those reported globally.
Main Methods:
- Retrospective analysis of 46 Omani patients diagnosed with ML between 1990 and 1990.
- Histopathological and immunological classification of Hodgkin's disease (HD) and non-Hodgkin's lymphomas (NHL) subtypes.
Main Results:
- Non-Hodgkin's lymphomas (NHL) constituted 65% of cases, with a predominantly diffuse pattern (83%) and high-grade type (70%).
- B-cell lymphomas accounted for 80% of NHL cases.
- The observed ML pattern in Oman showed unique characteristics, differing from Western, Far East, and Saudi Arabian data, with similarities to tropical African patterns.
Conclusions:
- The epidemiological profile of malignant lymphoma in Oman presents distinct features compared to other global regions.
- Further research is warranted to elucidate the specific factors contributing to these observed patterns in Oman.
