Intermittent fasting triggers interorgan communication to suppress hair follicle regeneration Intermittent fasting halts hair follicle regeneration by activating communication between adrenal glands and niche adipocytes, which in turn selectively induces apoptosis of hair follicle stem cells but not epidermal stem cells in the skin.

The next big thing in Triple Negative Breast Cancer:
VEGF/PD-1 Bispecifics.

Wonderful discussion by Dr. Thomas Grinda on the prospects.

Several Phase III studies planned.

Dr. Tesch poster looking at TILs in very young women (<40 yrs)

Including all tumor subtypes- TNBC, HR+ and HER-3

TILs vary by recent pregnancy, BRCA status etc.

Here TILs not associated w/ ethnicity

TILs again predict pCR

Great slide highlighting not only are TILs predictive of pCR...it also translates to being prognostic beyond pCR for good outcome and DFS.

Seems like we have a LOT of data on TILs now, why aren't they standardly provided on path reports???🧐

Isolated tumor cells (ITCs) after neoadj can’t chemotherapy have frequently been considered positive lymph nodes when considering axillary management and adjuvant therapy.

Important global study that suggests, as @maryamlustberg.bsky.social notes, less may be more!

Updated treatment algorithms for breast cancer now include adjuvant ribociclib and inavolisib, along with key trial names. Thrilled to see we're truly running out of space in HR+ disease—progress is here, with much more to come for all breast cancer subtypes!

Only 3 weeks to #SABCS24, a meeting that promises to significantly impact the way we treat breast cancer. It will feature phase 3 data with novel SERDs, novel ADCs, immunotherapy, ctDNA monitoring, important biomarker analyses & so much more. Here’s my top 10 abstracts list— see you in San Antonio!

Heterogeneity of Residual Disease After Neoadjuvant Systemic Therapy in Breast Cancer This review analyzes the heterogeneity of residual disease after neoadjuvant systemic therapy in patients with breast cancer.

#DrugDevelopment
“Uncovering the anatomic & biological intricacies of residual disease will allow for ⬆️ precision in postneoadjuvant treatments, moving beyond the binary paradigm of RD vs path CR, toward more tailored rescue strategies.” 💯
