Decreased HER2 expression in residual disease following neoadjuvant therapy in patients with HER2-positive breast cancer. () - Apr 26, 2023 - Abstract #ASCO2023ASCO_4226; In our retrospective cohort, decreased HER2 expression by IHC following neoadjuvant treatment was associated with lower recurrence rates. If confirmed, RD HER2 IHC expression could be used as a prognostic biomarker to select patients for more or less aggressive adjuvant therapy, stratify patients in adjuvant trials, and identify patients who may benefit from more intensive post therapy surveillance.

Incidence of hypomagnesemia in patients with HER2+ breast cancer treated with pertuzumab. () - Apr 26, 2023 - Abstract #ASCO2023ASCO_4182; Our results do not indicate clinical monitoring of hypomagnesemia is necessary for patients receiving P. >* The values were converted into categorical variables (Y/N), since both institutions had different lab reference values.**4th trial date unavailable for 2 patients. One patient received only 3 cycles of P; one patient transferred care elsewhere after 3 cycles of P.
- |||||||||| Evolution of breast cancer management in the Dominican Republic in the 21st century. () - Apr 26, 2023 - Abstract #ASCO2023ASCO_4119;
It highlights the efforts made to apply guidelines on breast cancer management in general and global objective response to neoadjuvant regimen. It also highlights the need to implement more primary prevention and early detection since 52% of patients belong to the locally advanced category.

Cardiac dysfunction (CD) among breast cancer survivors (BCS): Role of cardiotoxic therapy and cardiovascular risk factors. (Available On Demand; Poster Bd # 446) - Apr 26, 2023 - Abstract #ASCO2023ASCO_3673; In this large cohort of BCS followed longitudinally for an extended period, exposure to potentially cardiotoxic therapy results in a substantial burden of CD; the risk increases over time, and with CVRFs. These results provide evidence for close surveillance of BC survivors at increased risk of CD for extended periods, and aggressive management of CVRFs before, during and after BC.

The evolving landscape of chemotherapy for the treatment of early-stage breast cancer from 2006-2019: Results of a retrospective cohort study. (On Demand | Hall A; Poster Bd # 92) - Apr 26, 2023 - Abstract #ASCO2023ASCO_2699; While the prevalence of women receiving chemotherapy in our cohort has decreased since 2006, there has been a marked increase in neoadjuvant chemotherapy among those women receiving chemotherapy, as well as an increase in both the duration of chemotherapy treatment and number of associated chemotherapy administration visits, a pattern specifically observed in non-trastuzumab/pertuzumab containing regimens.The change in average duration and number of visits represents a shift in treatment patterns for patients and providers. Understanding trends in breast cancer chemotherapy is useful to inform clinical care and administrative planning for sites delivering chemotherapy for early-stage breast cancer.

(Available On Demand; Poster Bd # 454b) - Apr 26, 2023 - Abstract #ASCO2023ASCO_1021; P2 Clinically, pembrolizumab (K)-mediated ICI plus HER2-directed therapy with trastuzumab (H) was safe and demonstrated modest activity in H-resistant HER2-positive (HER2+) metastatic breast cancer...Moreover, the synergy of H and K with paclitaxel (T) may overcome the need for dual HER2-blockade with H plus pertuzumab (P)...Exploratory correlative studies will characterize potential immune biomarkers predictive of efficacy and/or toxicity.

Whole-genome sequencing based assessment of HER2 focal amplification for precision oncology of breast cancers. (Available On Demand; Poster Bd # 439) - Apr 26, 2023 - Abstract #ASCO2023ASCO_997; Among 28 patients who received six cycles of docetaxel/carboplatin/trastuzumab/pertuzumab neoadjuvant therapy followed by curative surgery, 21 patients had HER2 focal amplification and 14 (66.7%) achieved pathologic complete remission (pCR). Our analysis demonstrates that WGS enables better classification of the HER2 amplification status in breast cancer than IHC with ISH, suggesting WGS as a sensitive tool for screening breast cancers for anti-HER2-targeted therapies.

Decision value of the circulating tumor DNA on the adjuvant anti-Her2 regimens in patients with Her2-positive breast cancer treated with neoadjuvant therapy. (Available On Demand; Poster Bd # 388) - Apr 26, 2023 - Abstract #ASCO2023ASCO_946; Of the 117 patients enrolled, there were 18 patients receiving adjuvant T-DM1 and 99 receiving trastuzumab (N = 70) or trastuzumab plus pertuzumab (N = 29). The presence of ctDNA in patients with early-stage Her2-positive breast cancer after NAT was independently associated with disease recurrence; however, ctDNA(+) after NAT became inconsiderable when patients were treated with adjuvant T-DM1 therapy, which represented ctDNA(+) as an important factor determining adjuvant anti-Her2 regimen.

Given the expected rise in the burden of breast cancer globally, therapeutic advances and increased treatment utilization may further accelerate global patient benefit.

Review, Journal: Individualizing Curative-Intent Therapy in HER2-Positive Early-Stage Breast Cancer. (Pubmed Central) - Apr 25, 2023 Trastuzumab emtansine (T-DM1) has been shown to improve outcomes if pathological complete response (pCR) is not achieved, and adjuvant extended therapy with neratinib has increased disease-free survival (DFS) and may have an impact in central nervous system (CNS) recurrences...Immune infiltration, intrinsic subtype, intratumoral heterogeneity, and dynamic changes during treatment have been described as important prognostic and/or predictive features. The integration of all these factors will be key in the proper identification of the true risk, and individualized treatment strategy, for each patient.
