In patients responding to induction immunochemotherapy, R2M is better than RM for PFS but not for OS. Safety data in the R2M arm show higher toxicity.

The results on the first-line treatment of MCL patients under 66 years of age confirm the previously observed, significantly prolonged TTF due to the addition of high-dose ARA-C within a further median follow-up period of 5 years. With their data, the authors suggest that some patients can be functionally cured by optimal first-line treatment and may question future chemotherapy-free strategies in MCL.

In heavily pretreated MCL with a poor prognosis after several previous lines of therapy, the well-tolerated (and with a wide therapeutic index) pirtobrutinib showed promising efficacy. Updated data will be presented in the oral session.

Monotherapy with parsaclisib resulted in a rapid and sustained response. Parsaclisib had an acceptable safety profile and was generally well tolerated by BTK inhibitor-naïve patients with R / R-MCL. The authors' data suggest that parsaclisib could be a potential treatment option for patients with R / R-MCL.

The addition of bortezomib resulted in R-HAD increasing the time to treatment failure. This was mainly due to higher response rates. Relevant differences or long-term effects in terms of survival or toxicities were not observed.

R-BAC has sustained efficacy over time in elderly patients with newly diagnosed MCL, with a median OS of over 60 percent at 7 years. Thus, this regimen, which compared favorably to any other reported immunochemotherapy regimen (with or without maintenance therapy) in similar populations, has significantly affected the life expectancy of elderly patients with MCL.
