Molecular analysis of circulating and disseminated tumor cells (CTCs/DTCs) has great potential as a means for continuous evaluation prognosis treatment efficacy in near-real time through minimally invasive liquid biopsies. To realize this potential, however, methods molecular these rare must be developed validated. Here, we describe the integration imaging mass cytometry (IMC) using metal-labeled antibodies implemented on Fluidigm Hyperion Imaging System into workflow previously established...

Importance Melanoma in Black individuals has an annual incidence of approximately 1 100 000 people. Most studies melanoma patients have used population databases, which lack important, precise clinical details. Objective To identify patient-level and tumor-level characteristics patients.

Sarcomas constitute approximately 1% of adult cancers and 8%–10% paediatric cancers. Undifferentiated pleomorphic sarcoma (UPS) is a type soft-tissue (STS) characterised by dedifferentiated cancer cells. The most common sites metastasis for UPS include the lungs, liver, bones regional lymph nodes. Brain rare, affecting only 1%–8% STS patients. This report presents unique case woman in her 80s with TET2 -mutant metastatic to lung brain.
The inter- and intra-tumor heterogeneity of triple negative breast cancers (TNBC), which is reflected in diverse drug responses, interplays with tumor evolution.

Patients matched PDTX exhibited concordant responses neoadjuvant therapy two trial designs dosing schedules. This platform enabled...
Abstract Imaging mass cytometry (IMC) is a novel technology with the potential of multiplex proteomic profiling rare circulating and disseminated tumor cells (CTCs DTCs) immune from liquid biopsies. The high-definition single-cell analysis (HD-SCA) identifies CTCs DTCs by virtue morphometric fluorescent staining exact locations all cells, which could be further characterized using downstream genomics proteomics platform. This study aims to develop employ metal-labeled antibody panels for...
The disruption caused by the COVID-19 pandemic has disproportionately affected cancer patients' access to care. As a result, many specialists in United States, including oncologists, have adopted telemedicine-a transition largely made possible reforms insurer reimbursement schemes. Years after crisis, there will continue be steady demand for remote outpatient visits, particularly oncology. However, health system heavily influenced reimbursements, strategies optimize oncology care not...
ABSTRACT Triple negative breast cancers (TNBC) exhibit inter- and intra-tumour heterogeneity, which is reflected in diverse drug responses interplays with tumour evolution. Here, we use TNBC patient-derived xenografts (PDTX) as a platform for co-clinical trials to test their predictive value explore the molecular features of response resistance. Patients matched PDTX exhibited mirrored neoadjuvant therapy clinical trial. In parallel, additional clinically-relevant treatments were tested...
