Nanomedicine and combination therapy
Several studies developed nanoparticles, liposomes, metal-organic frameworks, lignin-based nanocarriers, or niosomes for delivery of doxorubicin, mitoxantrone, or phytochemical agents while addressing drug resistance, systemic toxicity, or tumor targeting. Nanoparticle formulations combining doxorubicin with sanguinarine were tested in parental and Adriamycin-resistant MCF-7 cells, PEGylated liposomes co-loaded doxorubicin with miR-145 mimics for in-vitro testing in MDA-MB-231 cells, and MUC-1 aptamer-conjugated Janus silverβmesoporous-silica nanoparticles combined doxorubicin delivery with P-glycoprotein antisense-mediated MDR suppression and photothermal therapy in drug-resistant MCF-7/ADR cells (38180322; 39101839; 39454415). Other platforms used redox/pH-responsive metal-organic frameworks for mitoxantrone, lignin nanoparticles with pH- and glutathione-responsive doxorubicin release, and niosomes for synergistic doxorubicinβpiperine delivery and reduced expression of cancer-stem-cell-associated markers (41137753; 41874975; 40782357).

Resistance and molecular targets
The studies investigate molecular determinants of resistance to endocrine therapy, CDK4/6 inhibitors, mTOR inhibitors, and cytotoxic drugs. NanoCurcumin was evaluated with tamoxifen in ER-positive disease in relation to MALAT1 and other long noncoding RNAs, while PCK1 was linked to Cyclin D3 and CDK4/6-inhibitor resistance and PMEPA1 was identified in everolimus- and ridaforolimus-resistant TNBC models with persistent mTOR signaling, PI3K/AKT activation, and TGF-Ξ²/KRAS signaling (41031251; 41748011; 41819443). Other work assessed tumor pharmacodynamics of the PARP inhibitor talazoparib in BRCA-mutated tumors and showed that HIV-protease inhibitors enhanced carfilzomib cytotoxicity in TNBC cells; lopinavir also increased intracellular carfilzomib availability and induced endoplasmic-reticulum stress and a pro-apoptotic unfolded protein response (38010394; 38969867).

Imaging and computational diagnosis
Machine-learning and radiomic methods were applied to non-sentinel lymph-node metastasis prediction, mammographic interpretation, and reducing unnecessary biopsies. A retrospective two-hospital DCE-MRI study combined radiomic scores with clinical factors to predict non-sentinel lymph-node metastasis in Chinese breast cancer patients with one or two positive sentinel lymph nodes, while radiomics, deep learning, and information fusion were used to evaluate BI-RADS 4 mammographic calcifications and reduce invasive biopsies of benign calcifications (38490840; 39633212). Other studies used global mammographic radiomic features to identify normal cases that radiology trainees found hardest to interpret, MOF-based electrochemical and colorimetric sensing to quantify HER-2, and 68Ga-FAPI PET/CT combined with MAMMI PET to assess residual tumor after neoadjuvant chemotherapy (39407048; 40712488; 41391941).

Local treatment and survivorship
Studies examined local treatments and treatment-related outcomes. In a bilateral TNBC mouse model, cryoablation of the primary tumor was examined for systemic immune effects in distant tumors, while a prospective randomized study compared intraoperative ultrasound with conventional breast-conserving surgery for achieving negative margins (39703517; 38901438). Clinical radiation studies evaluated hypofractionated regional nodal irradiation and single-fraction high-gradient partial-breast irradiation, while other studies evaluated moderate-intensity aerobic exercise in postmenopausal women receiving aromatase inhibitors and described very late radiation-induced brachial plexopathy after breast-cancer radiotherapy (40311918; 40912507; 40035875; 39348524).
