Activation of the anticipatory unfolded protein response (aUPR) by the small molecule 3,3-bis(4-hydroxyphenyl)-7-methyl-1,3,dihydro-2H-indol-2-one (BHPI) leads to necrotic cell death in a variety of cancer cells containing Estrogen Receptor alpha (ERα). A key feature of BHPI's mechanism of action is depletion of cellular ATP. Other pathways such as autophagy can regulate cellular energy levels and ATP production. We present data that suggests targeting both the aUPR and autophagy leads to a significant increase in cell death in T47D and TYS breast cancer cells treated with BHPI. This combination presents itself as a possible therapeutic strategy against breast cancer.

Importance: Frailty assessed at a single time point is associated with mortality in older women with breast cancer. Little is known about how changes in frailty following cancer treatment initiation affect mortality.
Objective: To evaluate the association between claims-based frailty trajectories following adjuvant chemotherapy initiation and 5-year mortality in older women with stage I to III breast cancer.

Purpose: The FAST-Forward study paved the way for ultrahypofractionation (UHF) in breast cancer. We prospectively registered and analyzed our case series receiving UHF + simultaneous integrated boost (SIB) to further reduce the treatment to a total of 5 days. The study aimed to present the 6-month early side effects results of the first patients treated with this scheme in 16 radiation oncology centers in Spain.

Objective: Persistent postoperative sensory loss significantly limits breast reconstruction following mastectomy. In addition, the absence of sensation profoundly impacts patients' physical well-being and overall quality of life. New surgical techniques involving nerve autograft intercostal nerve elongation have been introduced to neurotize reconstructed breasts.
