Improved Outcome of Human Immunodeficiency Virus-Associated Plasmablastic Lymphoma of the Oral Cavity in the Era of Highly Active Antiretroviral Therapy: A Report of Two Cases
Bibliographic record
Abstract
Plasmablastic lymphoma (PBL) is a recently described type of non-Hodgkin's lymphoma (NHL) that occurs in up to 3% of patients with HIV infection. Although the clinical-pathological features of several patients with HIV-associated plasmablastic lymphoma are documented, detailed description of clinical outcome is limited to isolated case reports. Generally, the response to lymphoma therapy is poor and survival is short. Response to highly active anti-retroviral therapy (HAART), however, has also been described. In this report, we describe the clinical course of two patients diagnosed with HIV-associated PBL in the era of HAART. One patient had a complete response to HAART, with a response-duration of 14 months, followed by relapse in the gastrointestinal tract several months after an anti-retroviral holiday. He is currently in complete remission (CR) eight months from diagnosis of relapse after receiving a full course of combination chemotherapy with modified CHOP, and 25 months from initial diagnosis. A second patient responded to brief chemotherapy in conjunction with HAART and is in clinical CR ten months from diagnosis. These cases illustrate that immunologic and virologic control with HAART may be beneficial for treating PBL and may possibly maintain continued CR. We advocate a high index of suspicion for primary PBL or its recurrence in patients with HIV infection, a history of low CD4 counts or high viral load, and oral or gastrointestinal symptoms.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
