Breast cancer is one of the most common causes of cancer related deaths in women. Currently, with the development of early detection, increased social awareness and kinds of treatment options, survival rate has improved in nearly every type of breast cancer patients. However, about one third patients still have increased chances of recurrence within five years and the five-year relative survival rate in patients with metastasis is less than 30%. Breast cancer contains multiple subtypes. Each subtype could cause distinct clinical outcomes and systemic interventions. Thereby, new targeted therapies are of particular importance to solve this major clinical problem. Aptamers, often termed "chemical antibodies", are functionally similar to antibodies and have demonstrated their superiority of recognizing target with high selectivity, affinity and stability. With these intrinsic properties, aptamers have been widely studied in cancer biology and some are in clinical trials. In this review, we will firstly discuss about the global impacts and mechanisms of breast cancer, then briefly highlight applications of aptamers that have been developed for breast cancer and finally summarize various challenges in clinical translation of aptamers.

Objectives: Medroxyprogesterone acetate (MPA), a steroid progesterone, is widely used to treat endometriosis, menstrual disorders, and uterine bleeding in clinical practice. However, the safety profile of MPA requires comprehensive evaluation.
Methods: This study performed a retrospective analysis using real-world data extracted from the US Food and Drug Administration Adverse Event Reporting System (FAERS) database.

Importance: Approximately one-third of patients with ERBB2 (formerly HER2 or HER2/neu)-positive (ERBB2+) metastatic breast cancer (MBC) develop brain metastasis. It is unclear whether patients with disease limited to the central nervous system (CNS) have different outcomes and causes of death compared with those with concomitant extracranial metastasis.
Objective: To assess overall survival (OS) and CNS-related mortality among patients with ERBB2+ breast cancer and a diagnosis of CNS disease by disease distribution (CNS only vs CNS plus extracranial metastasis).
Formation and evaluation of doxorubicin and cromoglycate metal-organic framework for anti-cancer activity.

Department of Chemistry, The University of Jordan, Amman, Jordan.
Aims: We develop and evaluate copper-based metal-organic frameworks (Cu-MOFs) incorporating cromolyn as a linker to enhance structural stability, drug delivery efficiency, and therapeutic potential, particularly for breast cancer treatment.
Materials & Methods: Two Cu-MOF formulations were synthesized: Cu-MOFs-BDC-DOX (using terephthalic acid) and Cu-MOFs-CROMO-DOX (using cromolyn as a linker). Characterization was performed using SEM/TEM for morphology, and FTIR, XRD, and TGA to confirm structural integrity.

Aims And Objectives: Appropriately timed cessation of systemic anticancer treatments is an important part of a patient's quality of life (QoL). We aimed to determine the right time to discontinue systemic anticancer therapy (SACT) and switch to the best supportive care for patients with advanced breast cancer (BC) who are nearing the end of life.
Methods: We identified 200 BC patients who died within 30 days after palliative SACT.
