[VIRTUAL] Sequencing IMPACT of (CDK4/ 6) Treatment Lines on Patient Outcomes for Metastatic Breast Cancer. () - Oct 3, 2020 - Abstract #ISPOREU2020ISPOR-EU_1445; CONCLUSIONS The result of the study suggests that the impact of Palbociclib for enhancing patient outcomes is dominating. Using line of Palbociclib prior to (Ribociclib )for treatingmetastatic breast cancer may have dominant effect onpatient outcomes as a treatment strategy one of the challenges facing such kind of analysisis availability ofsurvival dataand importance ofselection of appropriatepatient criteria from different stake holders prospective .

[VIRTUAL] Antitumor activity of Z-endoxifen (ENDX) is mediated via PKCβ1-dependent ERα loss and cell cycle arrest in ERα-positive breast cancer (Channel 2) - Oct 2, 2020 - Abstract #SABCS2020SABCS_1235; While targeting PKCβ1 kinase activity elicited no anticancer effects in ERα+ cells, PKCβ1 downregulation, either by siRNA or ENDX, resulted in profound ERα turnover, reduced protein levels of essential cell cycle mediators and profoundly inhibited cell proliferation. Furthermore, PKCβ1 protein expression is associated with TAM, but not ENDX, resistance, a finding whose clinical relevance is further magnified by identification of PRKCB amplification in metastatic ERα+ BC, confirming its potential importance in progression.

[VIRTUAL] Winpro: A window of opportunity study of endocrine therapy with and without prometrium in postmenopausal women with early stage hormone receptor-positive breast cancer () - Oct 2, 2020 - Abstract #SABCS2020SABCS_1102; Translational endpoints include definition of a predictive gene set biomarker for Ki67 reduction; tumor biomarkers after treatment, including apoptotic markers Bcl-2 and cleaved-caspase3, as well as protein and mRNA expression of ER, PR, AR, FoxA1, and CyclinD1; and levels of estrone, estradiol, E2, progesterone, testosterone, DHT, and DHEAS in serum and finger prick dried blood spot after treatment.Accrual: Enrolment commenced in February 2018 and 70 patients have been randomized from 7 sites to date (1 July 2020). Target accrual is 200 patients enrolled from 8 sites.Contact information: This study is led at The Kinghorn Cancer Centre, St Vincent’s Sydney Hospital Sydney, Australia, and funded by the Cancer Council of NSW and the NHMRC Translational Breast Cancer Project grant.

[VIRTUAL] Immune cell populations in peripheral blood of metastatic breast cancer patients under CDK4/6 inhibitors (OnDemand) - Oct 2, 2020 - Abstract #SABCS2020SABCS_977; MethodsA prospective cohort of metastatic ER+/HER2- BC patients treated with CDK4/6i (palbociclib or ribociclib) was included...All patients received letrozole or fulvestrant, together with LHRH agonist if premenopausal...Additionally, a decrease in total T (-2.38%/month, p =0.002), Treg subtype II (-2.52%/month, p =0.0076), CD8CM T (-3.30%/month, p =0.006), CD4CM T (-3.97%/month, p =0.002), γδ1CM subset of γδ T (-2.73%/month, p =0.047), NK (-0.99%/month, p =0.011), and CD8Eff T (-1.72%/month, p <0.001) cells was observed in CDK4/6i NResp subgroup, with no significant changes in Resp subgroup. Conclusions Results suggest that significant immune profile changes occur in metastatic ER+/HER2- BC patients with early progression to CDK4/6i and endocrine therapy.

[VIRTUAL] Fertility preservation for breast cancer patients before chemotherapy (OnDemand) - Oct 2, 2020 - Abstract #SABCS2020SABCS_807; Wider implications: We systematically investigated various aspects of ovarian stimulation for oocyte retrieval in breast cancer patients undergoing fertility preservation prior to chemotherapy, our review indicated that (1) random-start controlled ovarian stimulation protocol showed comparable oocyte yields with minimal delays of referral to initiate ovarian stimulation; (2) two ovarian stimulation cycles results in higher numbers of retrieved oocytes while back-to-back and conventional two cycles showed no significant differences; (3) combinations with letrozole demonstrated a safer way over tamoxifen and anastrozole in terms of lowering estradiol level during stimulation processes; (4) in vitro maturation of immature oocytes can maximize the numbers of oocytes for cryopreservation; and (5) regarding patients’ genetic backgrounds, those with BRCA mutations have lower AMH levels, but similar in numbers of retrieved oocytes to those without BRCA mutations. Nonetheless, we look forward to higher evidence-level studies to understand the clinical relevance of these protocols for ovarian stimulation in breast cancer patients desiring fertility preservation before chemotherapy.
