Real-World Challenges of Managing Diffuse Large B-Cell Lymphoma in a Developing Country

Area of Science:

• Hematology
• Oncology
• Public Health

Background:

• Diffuse large B-cell lymphoma (DLBCL) is a common non-Hodgkin lymphoma.
• Management of DLBCL in resource-constrained settings presents unique challenges impacting patient outcomes.

Purpose of the Study:

• To identify challenges and cancer care disparities in DLBCL management within resource-limited settings.
• To evaluate treatment patterns and outcomes for DLBCL patients in Pakistan.

Main Methods:

• A multicenter retrospective study involving 738 DLBCL patients from 12 centers in Pakistan.
• Patients were categorized into limited-resource and enhanced-resource settings based on national guidelines.

Main Results:

• The majority of patients (69.3%) were treated in limited-resource settings, with a median age of 47 years.
• Advanced-stage disease was prevalent (86.3%), and complete remission was achieved in 74.4% of evaluable patients.
• Median overall survival was 3.6 years, with a 5-year OS of 40%; however, follow-up data was missing for 46.8% of patients.

Conclusions:

• Patients in low- and middle-income countries often present with earlier onset and more advanced DLBCL.
• Inadequate record-keeping and high rates of loss to follow-up, particularly in limited-resource settings, hinder effective cancer care.
• Establishing a national lymphoma registry, improving data collection, and standardizing treatments are crucial for improving DLBCL patient outcomes.
