Liquid Biopsy Identifies Mutations Predicting Ovarian Cancer Treatment Response

Effective treatment of metastatic solid cancers is hampered by intrapatient heterogeneity, tumor evolution, and the paucity of representative tissue samples to guide treatment decisions. Analysis of circulating tumor DNA (ctDNA) is an approach with the potential of overcoming all three obstacles. More...

Technology Developed to Capture Tumor Cells

The roles and clinical values circulating tumor cells (CTCs) are under intensive investigation, yet most studies are limited by technical challenges in the comprehensive enrichment of intact and viable CTCs with minimal white blood cell (WBC) contamination. More...

Urinary Biomarkers Diagnose Serious Kidney Allergic Reaction

Acute interstitial nephritis is a condition marked by inflammation and swelling of the renal tubules, the tiny portals in the kidneys where blood is filtered. As a result, the tubules cannot properly reabsorb water and useful organic substances, such as glucose and amino acids, or secrete waste products such as urea and creatinine into urine. More...

Blood Test Measures Effectiveness of Aggressive Cancer Treatments

Blood tests that track the amount of tumor DNA can, after only one month of drug therapy, detect how well treatment is working in patients with skin cancer. In the USA, more than 7,200 individuals are expected to die from metastatic melanoma in 2019, with BRAF mutations playing a role in nearly half of such diagnoses. More...

Genomic Data Affects Prognosis of Advanced Prostate Cancer

Heterogeneity in the genomic landscape of metastatic prostate cancer has become apparent through several comprehensive profiling efforts, but little is known about the impact of this heterogeneity on clinical outcome. More...

Assay Stratifies Esophageal Cancer Patients for Treatment

The incidence of esophageal adenocarcinoma (OAC) in the Western world has risen six-fold in the last 40 years with the highest incidence occurring in the UK and there were about 9,200 cases of the disease reported in the UK in 2015. It accounts for 3% of cancer cases in the UK each year. More...

Protein Panel Accurately Differentiates Forms of Ovarian Tumors

A panel of eight proteins was found that distinguishes between the milder endometrioid (EC) and more deadly high-grade serous (HGSC) forms of ovarian cancer with 99.2% accuracy. More...
