Surveillance in Patients With Diffuse Large B Cell Lymphoma

Area of Science:

• Oncology
• Radiology

Background:

• Improved cure rates for diffuse large B cell lymphoma (DLBCL) raise questions about post-treatment surveillance.
• Clinical guidelines vary on the necessity of surveillance imaging for DLBCL patients in complete remission.

Purpose of the Study:

• To review current data on the efficacy and risks of surveillance imaging in DLBCL patients achieving complete remission.
• To evaluate the benefits versus harms of routine surveillance scans.

Main Methods:

• A comprehensive PubMed search was conducted using relevant keywords for English-language articles.
• Reference lists of identified articles and reviews were manually searched to identify additional relevant studies.
• Selected articles were reviewed for relevance to surveillance imaging in DLBCL.

Main Results:

• Several studies indicate no overall survival benefit from surveillance scans in DLBCL patients.
• Concerns exist regarding increased risk of secondary malignancies due to radiation exposure from scans.
• Contrasting international guidelines exist regarding surveillance computerized tomography (CT) scans.

Conclusions:

• The potential benefits of surveillance imaging in DLBCL must be weighed against costs, radiation risks, and lack of demonstrated survival advantage.
• Further evaluation is needed to establish optimal surveillance strategies for DLBCL survivors.
