Diffuse Large B-Cell Lymphoma

Burkitt Lymphoma
![Page 7: HIV and Non Hodgkin Lymphomadepts.washington.edu/...and_non_hodgkin_lymphoma.pdf · comprise 50% of the cancers in people living with HIV • We should offer age-appropriate cancer](https://reader034.vdocument.in/reader034/viewer/2022052007/601bf948a32a6716064549a1/html5/thumbnails/7.jpg)
• In the US, approximately 6% of all patients with diffuse large B cell lymphoma, and approximately 25% of patients with Burkitt lymphoma are HIV (+).
• These % vary by demographic group.

Malignancy and HIV
• In the HAART era, non AIDS-defining malignancies comprise 50% of the cancers in people living with HIV
• We should offer age-appropriate cancer screening to our HIV (+) patients
• Since 20% of HIV (+) people in the US don’t know their HIV status, recommend HIV testing in patients with anal cancer, NHL, Hodgkin lymphoma, or ITP

Lymphoma in HIV-Positive People
• 50-100 fold increased incidence of aggressive NHL (in comparison to HIV-negative people)
• Some increased incidence of Hodgkin lymphoma • Primary central nervous system lymphoma – CD4 cells <
50/µl (and often < 10/µl)

HIV-Associated NHL: Practical Approach
• Diffuse large B cell (most common) • Burkitt lymphoma • Primary CNS lymphoma (rare today) • Plasmablastic lymphoma (rare) • Primary effusion lymphoma (rare)

HIV-Associated NHL
• B symptoms common • Often extra nodal (liver, gastric, rectum, kidney, skin
involvement) • Clinically aggressive • Stage similarly to HIV (-) NHL

AIDS Malignancy Consortium Clinical Trials
• We are a core site for AMC clinical trials • AMC 075 R-EPOCH ± vorinostat for HIV (+) people with
diffuse large B-cell lymphoma and CD4≥50/µl

HIV-Associated DLBCL
• Multiple studies of CHOP or EPOCH variants ± Rituximab • EPOCH with concurrent or sequential rituximab (AMC 034) • concurrent better, OAS 70% at 2 years* • Short course EPOCH with dose-dense rituximab (NCI) • OAS 68% at 5 years • * 23/106 patients had Burkitt lymphoma

Treatment of HIV-Associated Diffuse Large B Cell Lymphoma
• Dose-adjusted R-EPOCH (preferred) or R-CHOP • Consider not using rituximab in patients with CD4 < 50/ml • HAART • Avoid zidovudine (more cytopenias) • Supportive care with peg-filgrastim, pneumocystis, candida,
HSV-2 prophylaxis

Prognosis
• As HAART improves, prognosis is defined mainly by lymphoma-related features, and less by HIV

HIV-Associated Burkitt Lymphoma
• About 1/3 as common as DLBCL • Occurs at a higher CD4 count • Clinically very aggressive • Often involves extra nodal sites
![Page 20: HIV and Non Hodgkin Lymphomadepts.washington.edu/...and_non_hodgkin_lymphoma.pdf · comprise 50% of the cancers in people living with HIV • We should offer age-appropriate cancer](https://reader034.vdocument.in/reader034/viewer/2022052007/601bf948a32a6716064549a1/html5/thumbnails/20.jpg)
HIV-Associated Burkitt Lymphoma
• Treated 29 patients with DA-EPOCH-R, plus intrathecal therapy
• 10 were HIV (+), 19 were HIV(-) • All in CR, median follow up of 4-5 years
![Page 21: HIV and Non Hodgkin Lymphomadepts.washington.edu/...and_non_hodgkin_lymphoma.pdf · comprise 50% of the cancers in people living with HIV • We should offer age-appropriate cancer](https://reader034.vdocument.in/reader034/viewer/2022052007/601bf948a32a6716064549a1/html5/thumbnails/21.jpg)
Plasmablastic Lymphoma
• Rare (~3% of HIV-associated NHL) • Mass lesion in gums/palate, but can be elsewhere (liver, GI
tract, lungs, muscle) • Often diagnosed by dentists • Poor outcome (median survival 11 months; 5 year survival
24%), most deaths due to lymphoma

Summary
• People living with HIV have a long expected survival on HAART
• As the HIV (+) population ages, ~50% of the cancers are non AIDS-defining malignancies so think about age appropriate cancer screening.
• As HAART improves, prognosis is defined more by tumor-related features and less by HIV
• It is key to have these patients on HAART
