Blood Tumor Markers May Warn When Lung Cancer Patients Are Progressing on Targeted Treatments

Excerpt:

“For many years, oncologists have known that cancers can secrete complex molecules into the blood and that levels of these molecules can be easily measured. These so-called ‘tumor markers’ are traditionally associated with a single dominant cancer type, for example Prostate Specific Antigen (PSA) linked to prostate cancer, Carcinoembryonic antigen (CEA) to colorectal cancer, CA125 to ovarian cancer, CA19.9 to pancreatic cancer and CA27.29 to breast cancer. However, the real challenge has been to determine a practical use for these markers. They don’t appear to be useful as a means of screening otherwise healthy people for evidence of underlying cancers.”

The CAR T-Cell Treatment: Will It Work for Solid Tumors?


Chimeric antigen receptor (CAR) T-cell therapy is a new, immune system-based cancer treatment that has garnered recent media attention. In a clinical trial, CAR T-cell treatment left no signs of tumors in 70% to 90% of children and adults with the aggressive blood cancer acute lymphocytic leukemia (ALL). ALL is almost always fatal, and the results observed with CAR T-cell treatment are nothing short of spectacular. Continue reading…


Combination of Mesothelin and CEA Significantly Improves the Differentiation between Malignant Pleural Mesothelioma, Benign Asbestos Disease, and Lung Cancer

Soluble mesothelin-related peptides (SMRP) have been reported as potential markers for the diagnosis of malignant pleural mesothelioma (MPM). The diagnostic yield of the mesothelin test can be considerably improved when combined with a CEA test with regard to the differential diagnosis between MPM and LC and between MPM and benign asbestos disease.
