Primary diffuse large B-cell lymphoma of the uterus: A SEER database analysis

Area of Science:

• Oncology
• Hematology
• Epidemiology

Background:

• Uterine diffuse large B-cell lymphoma (DLBCL) is an uncommon malignancy.
• Existing research on uterine DLBCL primarily consists of case reports and series.
• A comprehensive analysis of demographic, clinical, and survival data is needed.

Purpose of the Study:

• To present a novel case of uterine DLBCL.
• To investigate the demographic and clinical characteristics of primary uterine DLBCL.
• To compare survival outcomes between uterine DLBCL and non-uterine DLBCL.

Main Methods:

• Utilized the Surveillance, Epidemiology, and End Results (SEER) database.
• Included women aged 18 years and older diagnosed with primary DLBCL between 1975 and 2017.
• Compared characteristics and survival between uterine and non-uterine DLBCL cohorts.

Main Results:

• The most frequent sites for uterine DLBCL are the cervix, endometrium, and corpus uteri.
• Non-uterine DLBCL cases were diagnosed in older patients compared to uterine DLBCL.
• Uterine DLBCL patients demonstrated superior survival rates compared to non-uterine DLBCL patients.
• Treatment during the rituximab era correlated with improved survival outcomes.
• Elderly and African American patients experienced poorer overall survival.

Conclusions:

• Uterine DLBCL exhibits distinct demographic and survival characteristics compared to non-uterine DLBCL.
• Early diagnosis and treatment, particularly with rituximab, are crucial for improving patient outcomes.
• Further research is warranted to understand disparities in survival among specific patient cohorts.
