Encouraging direction, but not yet definitive.
This retrospective cohort study of 32 previously untreated CD5-positive DLBCL patients demonstrates high response rates (ORR 100% after 3 cycles, CRR 71.9%) and 2-year survival rates (PFS 70%, OS 82.7%) with first-line Pola-R-CHP. Failure to achieve complete response after interim PET/CT (3 cycles) was a significant predictor of inferior progression-free and overall survival (PFS HR 18.1, p=0.02; OS HR 12.3, p=0.033), suggesting interim response guides prognosis in this high-risk population.
Multicenter, retrospective cohort study. Previously untreated CD5-positive DLBCL patients enrolled between April 2023 and February 2025; median age 63.5 years; 78.1% stage III-IV; 59.4% IPI score ≥3.. Intervention: Pola-R-CHP (polatuzumab vedotin combined with rituximab, cyclophosphamide, doxorubicin, and prednisone) as first-line therapy.. n = 32. Multicenter study; specific countries/regions not specified in source text..
Overall response rate 100% after 3 cycles with complete response rate 71.9% At end of treatment, ORR 93.8% and CRR 75% 2-year progression-free survival 70% and overall survival 82.7% after median follow-up 17.9 months
Grade 3-4 adverse events in 31.3% of patients, with neutropenia most common
For clinicians treating CD5+ DLBCL with Pola-R-CHP, interim PET/CT response after 3 cycles appears prognostically informative; failure to achieve complete response at this timepoint predicts substantially worse survival outcomes and may warrant consideration of treatment modification strategies. The high 2-year survival rates suggest Pola-R-CHP is effective for this historically poor-prognosis subtype, though confirmation in larger prospective studies is needed.
Retrospective multicenter study showing high response rates and 2-year survival outcomes for a high-risk CD5+ DLBCL population treated with Pola-R-CHP, with interim PET response predicting survival, but limited by small sample size, retrospective design, and short median follow-up.

Background. CD5-positive diffuse large B-cell lymphoma (DLBCL) is an aggressive subtype with poor outcomes. Following the approval of Pola-R-CHP in China, this study aimed to evaluate its efficacy as initial therapy for this high-risk population.Methods. We conducted a multicenter, retrospective study of previously untreated CD5-positive DLBCL patients who received Pola-R-CHP as first-line therapy between April 2023 and February 2025. Treatment response was assessed by PET/CT after 3 cycles and at the end of treatment.Results. Among 32 enrolled patients (median age 63.5 years), 78.1% had stage III-IV disease and 59.4% had an International Prognostic Index score ≥3. The overall response rate (ORR) was 100% after 3 cycles, with a complete response rate (CRR) of 71.9%. At end of treatment, the ORR and CRR were 93.8% and 75%, respectively. After a median follow-up of 17.9 months, 2-year progression-free survival (PFS) and overall survival rates (OS) were 70% and 82.7%. After adjusting covariates, failure to achieve a complete response (CR) after 3 cycles was a predictor of inferior survival [PFS HR: 18.1, p = 0.02; OS HR: 12.3, p = 0.033]. Grade 3-4 adverse events occurred in 31.3% of patients, with neutropenia being most common.Conclusions. CD5-positive DLBCL patients exhibited rapid and promising responses to first-line Pola-R-CHP with an acceptable safety profile. Interim response assessment is a potential prognostic factor. In instances where CR is not attained by the interim PET/CT, it is advisable to consider treatment modification, as this may indicate a potential failure to achieve CR.
