GIST

Metastatic disease accounts for the vast majority of cancer-related deaths. Ensuring a definitive diagnosis and the most effective treatment in a timely fashion is essential for extending life expectancy.

Researchers for Caris Life Sciences have used the company's proprietary tumor profiling platform to identify biomarkers in GIST that may be used to identify more effective therapeutic regimens for individuals with TKI-resistant GIST.

A 12-gene test for breast cancer recurrence after ductal carcinoma in situ (DCIS) distinguished high- and intermediate- risk patients from those with a low risk. These results were presented at the 2014 San Antonio Breast Cancer Symposium.

Using more accurately defined data than previous studies, a team of investigators at the UCSD School of Medicine has characterized the epidemiology of GIST.

Tanios Bekaii-Saab, MD, Section Chief, Gastrointestinal Oncology, associate professor, Internal Medicine, Pharmacology, The Ohio State University, discusses an analysis of two targeted drugs for the treatment of patients with colorectal cancer (CRC).

Last week, the US Food and Drug Administration (FDA) announced two steps it will take to ensure the safety and utility of certain diagnostic tests.

The FDA has approved the radioactive diagnostic imaging agent Lymphoseek injection to guide sentinel lymph node biopsy in patients with cancer of the head and neck.

A cell-cycle gene array test demonstrated independent value for predicting metastatic progression after surgery for organ-confined renal cell carcinoma (RCC) of clear cell histology.

The FDA has approved ramucirumab as a treatment for patients with unresectable gastric cancer or GEJ adenocarcinoma following fluoropyrimidine- or platinum-containing therapy, based on a significant extension in overall survival (OS).

Sukumar Nagendran, MD, vice president, medical affairs, Quest Diagnostics, describes BRCAvantage, a test to detect BRCA1 and BRCA2 genes.

Determination of HER2 status has become an important part of the workup of patients with advanced esophagogastric cancer, given recent data from a phase III trial (ToGA) indicating that trastuzumab, an anti-HER2 monoclonal antibody, prolongs survival in these patients.

Meredith C. Henderson, PhD, Head, R&D, Provista Diagnostics, describes the dtectDx Breast test.

A new study suggests that even tumor cells with a common genetic background can display functional heterogeneity.
