Breast cancer is the most common malignancy occurring in women worldwide. More than 90% of patients present with localized disease are treated with curative intent; however, recurrence can occur with development of metastatic lesions. Frequently associated with extra-hepatic lesions, localized treatments (surgery or stereotaxic body radiotherapy) are rarely proposed in liver lesions. Y radioembolization has extensively been evaluated in colorectal cancer, but its role in breast cancer with isolated liver metastases remains largely unknown. Pre-existing liver diseases are known risk factors for Y induced liver toxicity. Not considered as an excluding factor for this treatment, data are limited regarding its safe use with cholangitis. We report a successful control of liver metastases by Y radioembolization in a breast cancer patient.

Breast cancer is the leading cause of cancer-related death and the most common cancer among women worldwide. It is crucial to identify potentially modifiable risk factors to intervene and prevent breast cancer effectively. Sleep factors have emerged as a potentially novel risk factor for female breast cancer.

Objective(s): Some forms of breast cancer such as triple-negative phenotype, are serious challenge because of high metastatic cases, high mortality and resistance to conventional therapy motivated the search for alternative treatment approaches. Nanomaterials are promising candidates and suitable alternatives for improving tumor and cancer cell treatments.
Materials And Methods: Biosynthesis of ZnO NPs by help of Berberis integerrima fruit extract, has been done.

Rearranged during transfection (RET) kinase is a validated therapeutic target for various cancers characterized by RET alterations. Although two selective RET inhibitors, selpercatinib and pralsetinib, have been approved by the FDA, acquired resistance through solvent-front mutations has been identified rapidly. Developing proteolysis targeting chimera (PROTAC) targeting RET mutations offers a promising strategy to combat drug resistance.

Polymer based nanoformulations offer substantial prospects for efficacious chemotherapy delivery. Here, we developed a pH-responsive polymeric nanoparticle based on acidosis-triggered breakdown of boronic ester linkers. A biocompatible hyaluronic acid (HA) matrix served as a substrate for carrying a doxorubicin (DOX) prodrug which also possesses natural affinity for CD44 cells.

Tumor-specific cytotoxic T cell immunity is critically dependent on effective antigen presentation and sustained signal transduction. However, this immune response is frequently compromised by the inherently low immunogenicity of breast cancer and the deficiency in major histocompatibility complex class I (MHC-I) expression. Herein, a chimeric peptide-engineered stoichiometric polyprodrug (PDPP) is fabricated to potentiate the cytotoxic T cell response, characterized by a high drug loading capacity and precise stoichiometric drug ratio, of which the immunogenic cell death (ICD) inducer of protoporphyrin IX (PpIX) and the epigenetic drug of decitabine (DAC) are condensed into a polyprodrug called PpIX-DAC.
