Aim: Guidelines list atezolizumab with nab-paclitaxel (ANP) as the preferred first-line (1L) therapy for metastatic triple-negative breast cancer (mTNBC) with PD-L1 expression ≥1%, but which clinical attributes impact ANP prescribing? Materials & methods: Medical oncologists participated in a discrete choice experiment (DCE) with four hypothetical mTNBC clinical scenarios to assess influences of: PD-L1 expression, menopausal status, prior adjuvant therapy and bulky liver metastases. Results:  A total of 47% chose ANP in 1L irrespective of menopausal status, prior adjuvant therapy or tumor bulk. PD-L1 expression was the only attribute with a significant impact on ANP preference, with 69% choosing ANP for those with ≥1% expression versus only 26% for those with <1% (p < 0.00001). Conclusion: ANP choice for 1L mTNBC deviated from guidelines.

Objective: To determine the perceptions of US community-based hematologists/oncologists regarding approved CAR-T therapies in relapsed/refractory large B-cell lymphoma and barriers to their adoption in practice. Materials & methods: In February and November 2019, US physicians with diverse geographic representation submitted responses via a web-based survey prior to or via an audience response system at the live meetings. Results: In February and November, 46 and 29% of physicians indicated that they had not referred any patients for CAR-T therapy, respectively. Cumbersome logistics, high cost and toxicity were defined as major barriers to prescribing CAR-T therapy. Conclusions: These findings highlight a need to improve processes, and address costs, to ensure timely access to this potentially curative therapy for relapsed/refractory large B-cell lymphoma patients.
