In this review, we identify and address the unique challenges encountered in the care of OA with DLBCL. We elaborate on the role and limitations of current geriatric assessment (GA) tools and ways to incorporate fitness in therapeutic decision making. We suggest best practices to implement GA in routine practice and clinical trials. The most widely used tool is simplified GA (sGA) which categorizes patients into fit, unfit and frail groups. Patients who are fit benefit from full dose/curative approach, whereas consideration should be made to reduce the intensity of chemotherapy for unfit patients. Frail patients with DLBCL are a major unmet need without any satisfactory treatment options. Ongoing investigations combining novel therapies into chemotherapy-free regimens are underway with promising early results. In the relapsed/refractory (R/R) setting, anti-CD19 CAR-T cell therapy (CART) is now the standard of care for primary refractory disease or relapse within 12 months of completing therapy. Autologous stem cell transplant is still a consideration for fit OA with relapse >12 months after completing therapy. The recent approval of bispecific antibodies is a welcome advance that will greatly benefit OA not eligible for CART. Other regimens available for patients ineligible for CART or for those who experience progression post-CART include polatuzumab-rituximab±bendamustine, tafasitamab-lenalidomide, loncastuximab or chemotherapy-based approaches such as rituximab-gemcitabine-oxaliplatin.

While BTKi guidelines exist, practical differences between BTKis—such as drug interactions and tolerance—are not fully addressed. Therefore, a consensus on acalabrutinib use would benefit the medical community. This 2-round Delphi study involved hematologists, pharmacists, cardiologists, dermatologists, and nurse practitioners throughout France to establish consensus-based practical guidance on managing adverse events (AEs) associated with acalabrutinib in chronic lymphocytic leukemia. Key findings highlighted the need for a hospital pharmacist to analyze drug interactions before starting acalabrutinib. Additionally, the experts’ opinion was to avoid the concomitant use of acalabrutinib with strong CYP3A inhibitors due to an increased risk of toxicity and with strong CYP3A inducers due to potential efficacy concerns. Importantly, our study did not find contraindications for acalabrutinib in patients with current or previous atrial fibrillation. The panel emphasized the importance of measuring blood pressure at every clinical visit for patients treated with acalabrutinib and opposed the initiation of acalabrutinib in patients on both aspirin and clopidogrel. For invasive dermatological or dental procedures, acalabrutinib should be discontinued 4 days prior and resumed 48 hours postprocedure in the absence of bleeding. Additionally, patients should be informed about the risk of headaches, particularly during the first month of treatment, and paracetamol use in combination with caffeine is recommended for managing grade ≥ 2 headaches under acalabrutinib treatment. This Delphi study underscored the effectiveness of a collaborative process in enhancing the management of acalabrutinib-associated AEs.</div></div>","PeriodicalId":10348,"journal":{"name":"Clinical Lymphoma, Myeloma & Leukemia","volume":"25 3","pages":"Pages e173-e181"},"PeriodicalIF":2.7,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142638596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
