Take-Home Message

  • In TROPiCS-02, sacituzumab govitecan compared with standard chemotherapy in metastatic HR-positive breast cancer lead to an improvement in PFS.
  • This establishes another new antibody–drug conjugate standard.

1002 Results from the phase 1/2 study of patritumab deruxtecan, a HER3-directed antibody-drug conjugate (ADC), in patients with HER3-expressing metastatic breast cancer (MBC). IE Krop, N Masuda, T Mukohara, et al

Take-Home Message

  • Phase I data from the novel HER3 antibody–drug conjugate patritumab deruxtecan is presented.
  • Will this lead to further development of another antibody–drug conjugate with the same payload as T-DXd but a different target?

LBA1003 Overall survival (OS) with first-line palbociclib plus letrozole (PAL+LET) versus placebo plus letrozole (PBO+LET) in women with estrogen receptor–positive/human epidermal growth factor receptor 2–negative advanced breast cancer (ER+/HER2− ABC): Analyses from PALOMA-2. RS Finn, HS Rugo, VC Dieras, et al

Take-Home Message

  • PALOMA-2 will answer if there is an overall survival benefit with palbociclib in a first-line setting.
  • To date we have data with ribociclib in this setting with OS benefit but haven’t yet seen mature data on palbociclib or abemaciclib.

LBA1004 A randomized, phase II trial of fulvestrant or exemestane with or without ribociclib after progression on anti-estrogen therapy plus cyclin-dependent kinase 4/6 inhibition (CDK 4/6i) in patients (pts) with unresectable or hormone receptor–positive (HR+), HER2-negative metastatic breast cancer (MBC): MAINTAIN trial. K Kalinsky, MK Accordino, C Chiuzan, et al

Take-Home Message

  • DESTINY-Breast 04 represents a paradigm shift in breast oncology wherein targeting low expression of a receptor with an antibody–drug conjugate leads to improvements in PFS and OS compared with standard chemotherapy.
  • T-DXd will be a new standard of care for metastatic HR-positive HER2-low breast cancer, and we will need to learn how to appropriately test for HER2-low expression to optimize patient selection.

EARLY-STAGE BREAST CANCER

Oral Abstract Session: Breast Cancer—Local/Regional/Adjuvant
Tuesday, June 7, 2022; 10:45 AM–1:45 PM EDT

LBA501 LUMINA: A prospective trial omitting radiotherapy (RT) following breast conserving surgery (BCS) in T1N0 luminal A breast cancer (BC). TJ Whelan, S Smith, TO Nielsen, et al

503 Event-free survival by residual cancer burden after neoadjuvant pembrolizumab + chemotherapy versus placebo + chemotherapy for early TNBC: Exploratory analysis from KEYNOTE-522. L Pusztai, C Denkert, J O'Shaughnessy, et al

Take-Home Message

  • This exploratory analysis of the KEYNOTE-522 trial assessed event-free survival in terms of residual cancer burden in patients with early TNBC receiving pembrolizumab in addition to chemotherapy. After a median follow-up at 39.1 months (data cutoff), residual cancer burden had eased in those patients randomized to pembrolizumab. Fewer patients in the pembrolizumab arm, than in the placebo arm, across all degrees of residual cancer burden experienced distant recurrence.
  • Neoadjuvant pembrolizumab can improve survival in patients with early TNBC. Event-free survival was better in TNBC patients with residual cancer burden receiving pembrolizumab, compared with those randomized to placebo. The higher the degree of residual cancer burden, the worse the event-free survival.

Take-Home Message

  • Phase I data from the novel HER3 antibody–drug conjugate patritumab deruxtecan is presented.
  • Possibly this is a new type of treatment; will it lead to further development of another antibody–drug conjugate with the same payload as T-DXd but a different target?

E13042 Diagnosis of asymptomatic bone metastases from breast cancer. 

JN Krokhmal, LY Rozenko, EM Frantsiyants, et al

Take-Home Message

  • Some patients with ER+/HER− disease are diagnosed with bone metastases many years later, even 2 decades after completing their original treatment. However, they likely have been harboring evidence; if a bone scan had been done, the metastases could have been found much sooner. The question then is if it is better to leave things alone and wait for physical symptoms before we do a staging workup.
  • Some patients have said they were glad they didn't know they had metastases because it gave them 10 years of feeling good and not worrying. Others have wondered if their disease, limited to the bones, could have been treated earlier.

1044 Prognostic implications of HER2Neu-low in metastatic breast cancer. S Hasan, Z Neubauer, RH Press, et al

Take-Home Message

  • HER2 testing has been challenging from the outset. Having to do multiple tests to figure out if the cancer is HER2-positive or HER2-negative has always been confusing to patients.
  • In the way that hormone receptors are "slightly positive," should we more aggressively treat disease that has some degree of HER2 positivity?

1013 Effect of socioeconomic status as measured by Neighborhood Deprivation Index on survival in metastatic breast cancer. SP Narayanan, MQ Rosenzweig, et al

Take-Home Message

  • Where someone lives shouldn't determine the likelihood that she will die of breast cancer. We know, however, that health disparities associated with socioeconomic status, geography, education level, unemployment, and other factors can lead to higher stage of breast cancer at diagnosis and greater likelihood that a woman will die from the disease.
  • The needs in vulnerable communities is great, and easy access to government grants can result in better community outreach and successful partnerships with community leaders to bring women in for mammography screening and education, while also providing navigation services so that women are diagnosed earlier and have a better shot at survival.
