Roche Launches Thyroid and Lung Cancer Marker Assays

Product news

Three automated assays, that will allow laboratories to provide clinicians with information to aid the diagnosis and monitoring of cancer patients, have been added to the extensive Roche assay menu.

As part of its portfolio for the diagnosis and monitoring of patients with thyroid cancer, the next generation Roche Elecsys® Tg II automated assay offers improved sensitivity and precision. Thyroglobulin (Tg) testing is used in post operative follow up of patients with differentiated thyroid carcinoma (DTC). After total thyroidectomy, detectable levels of serum Tg are indicative of persistent or recurrent DTC. The new assay’s higher sensitivity potentially allows earlier detection of such persistence or recurrence, providing clinicians with the information they need to instigate rapid treatment.

The automated Elecsys® Calcitonin assay is another important tool addressing clinical needs in thyroid health management. In up to 10 % of all thyroid carcinoma patients a medullary thyroid carcinoma (MTC) is identified.10 MTC produce elevated serum concentrations of calcitonin and can be diagnosed with an exceptional degree of accuracy and specificity by the Elecsys Calcitonin assay. Consolidation of the Elecsys Tg II and Calcitonin assays on to one automated platform allows the diagnosis of the majority of thyroid cancers.

The third assay to be added to the Roche portfolio aids differential diagnosis in lung cancer and management of small cell lung cancer (SCLC) patients. SCLC accounts for approximately 20% of lung cancer cases and is an aggressive neoplasm of rapid growth with high sensitivity to chemo- and radiotherapy. Progastrin-releasing Peptide (ProGRP) is elevated in 68–86% of patients with SCLC. Additionally, as there is often metastasis into regional lymph nodes and/or distant organs at the time of SCLC diagnosis, quantitative determination of ProGRP in human serum and plasma using the fully automated Elecsys ProGRP assay can provide essential information for rapid patient management.

AntibodiesAntibodies are used in techniques such as confocal and fluorescence microscopy, flow cytometry, ELISA, ELISPOT, immunohistochemistry, western blotting and immunopreciptation. Select specific antigen reactivity, high specific affinity, low non-specific binding, monoclonal or polyclonal, primary or secondary antibodies and associated conjugates such as an enzyme or dye for visualization.Point-of-CarePoint-of-Care Testing (POCT) or Near Patient Testing (NPT) products are available for urine, blood and other clinical chemistry analyses. POCT includes: blood glucose testing, blood gas and electrolytes analysis, rapid coagulation testing (PT / INR), rapid cardiac markers diagnostics, drugs of abuse screening, urine strips testing, pregnancy testing, fecal occult blood analysis, food pathogens screening, hemoglobin diagnostics, infectious disease testing and cholesterol screening.BiomarkersBiomarkers are biological markers which can be measured and evaluated to indicate a biological state. The use of biomarkers in research and diagnosis can indicate a normal or disease state or drug response of cells / tissues. Biomarkers include genetic markers, cell surface markers such as antigens, antibodies or receptors and secreted molecules such as cytokines. An assay system is required for identification of biomarkers. :Clinical ChemistryBiochemistry (or clinical chemistry) involves the analysis of bodily fluids using chemical tests. Techniques used include HPLC, chromatography, spectroscopy, mass spectrometry, immunochemical, electrophoresis, turbidometric / spectrophotometric assay, MRI and ISE analysis. Tests are often carried out on plasma or serum but urine (urinalysis) and fecal specimens are also processed.Cancer DiagnosticsThere are a wide variety of diagnostic tests for cancer available, and this range continues to expand as our knowledge of cancer improves. Current diagnostic methods include biopsy, imaging and blood tests for known biomarkers. New methods in research development include liquid biopsies and cancer breathalyzers.Cancer ResearchAlthough cancer is often referred to as a single condition, it actually consists of more than 100 different diseases. Microscopy, mass spectrometry, high throughput sequencing and flow cytometry are some of the most common techniques employed in cancer research labs.Lung CancerLung cancer is a leading cause of cancer-related deaths worldwide, often diagnosed at an advanced stage. Research focuses on early detection, targeted therapies, and personalized treatment strategies.

Biomarkers can be used to diagnose presence of a disease and indicate disease severity. The discovery of new biomarkers is incredibly valuable in the field of diagnostics.
