To identify pathology-proven positive nodes regardless of visual changes after NST, breast biopsy clips or markers are inserted under ultrasound guidance as part of standard care, though most markers are used off-label in the axilla. However, clipped nodes may be difficult to visually confirm with ultrasound after a pathological complete response. This can affect the ease of executing subsequent procedures, such as surgical resection, because identifying the marked or clipped nodes in these cases is problematic. The mechanisms that affect these changes in clip conspicuity are poorly understood, making it challenging to improve ultrasound conspicuity of clips in the clinical setting. The aim of this study is to determine which of these mechanisms are inherent to ultrasound as an imaging modality and if they can be accounted for by adjustments to ultrasound scanner settings.</p><p><strong>Methods: </strong>The effect of viewing angle on brightness is assessed in multiple imaging targets, including five commercially-available clips, suspended in gelatin phantoms.

In recent years, systemic therapies such as trastuzumab deruxtecan and tucatinib have been reported effective for human epidermal growth factor receptor 2 (HER2)-positive breast cancer, however, these cannot be used for all MC. The difficulty in diagnosing and treating MC is attributed to its diverse pathology. As a result, in clinical practice, diagnosis is often delayed, and symptoms persist. This review focuses on whether neurological symptoms can be effectively alleviated even with unestablished treatments by classifying the pathology of MC into meningitis, hydrocephalus-related intracranial hypertension symptoms, focal brain damage such as epilepsy, cranial nerve disorders, and spinal cord symptoms and evaluating the diagnosis and condition. Hydrocephalus can be managed with drainage and ventriculoperitoneal shunt surgery, and meningitis symptoms and cranial nerve disorders can be managed with whole brain radiotherapy. Antiepileptic drugs are essential for epilepsy, and supportive care is necessary, as are steroids for cranial nerve disorders. However, MC is not caused by a single condition but can occur in combination thus the therapeutic effectiveness of palliative therapy for neurological symptoms is currently unknown, and research is limited. In the future, if a lineup of highly effective systemic therapies such as tyrosine kinase inhibitors for <i>ALK</i> gene-positive lung cancer is established, treatment strategies for MC may change.
