SIGNIFICANCE: We identified blood protein biomarkers for each stage of breast cancer by analyzing tissue-based transcriptome and blood-based proteome data from patients. To our knowledge, this is the first time to try to identify blood protein biomarkers for different stages of breast cancer via ...
PSA is a protein made only by prostate cells, and in cancer, PSA levels can rise as tumour cells multiply, but they also rise as a man's prostate gland grows with age, and some men with cancer have low PSA levels; so the test is considered imperfect. The authors found that a patient...
Blood protein testing Electrophoresis is a test that examines various proteins in the blood. This can help identify various immunoglobulins, which are elevated in people with multiple myeloma. A bone marrow biopsy may help confirm the diagnosis of blood cancer. Complete blood count (CBC) A complete...
For one, levels of CA 19-9 often rise only in the later stages ofpancreatic cancer, according to Castro, an oncologist at Massachusetts General Hospital in Boston. Plus, a spike in the protein is not specific to the cancer. It can go up when the pancreas is inflamed, for example, or ...
Prostate cancer patients whose tumors contain a shortened protein called AR-V7, which can be detected in the blood, are less likely to respond to two widely used drugs for metastatic prostate cancer, according to results of a study led by researchers at
testing. Notably, the baseline blood test was only an early version of a multi-analyte test, called CancerSEEK. Recently, the updated version of CancerSEEK incorporating genetic and protein biomarkers showed sensitivities of 69–98% for the detection of five common cancer types (ovary, liver, ...

Pancreatic cancer is an especially tough cancer to beatbecause it usually isn't detected until late in the disease. But a new blood test that uses two protein markers is showing promise for picking it up earlier, researchers report. The blood test is still in the investigative stages. A new...
Cytoplasmic DNA emerges as a consequence of genomic instability. However, its potential role in disease diagnosis has yet to be fully explored. Here we analyzed DNA remnants in mature red blood cells (rbcDNA) from both healthy individuals and cancer pati
Testing for the presence of specific cancer protein 'fingerprints' in the blood of lung cancer patients may be a useful means of identifying a subgroup whose tumors are more likely to shrink when treated with the drug erlotinib, especially when other testing methods are unavailable, according to...
