osmanthus Re: Test Tumor M2-PK 07.05.09, 14:23 Tumor M2-PK screening for the early detection of colorectal tumors and polyps Preliminary clinical studies in Germany, England and Ireland, which tested the detection of fecal Tumor M2-PK as a biomarker for the early detection of colorectal tumors (= bowel cancer), have revealed sensitivities between 73% (in the only published study) and 97 % (in an unpublished conference poster presentation). This means that the test was positive in between 73 and 97 out of every 100 colorectal tumor patients. For polyps with a diameter larger than 1 cm the sensitivity was 60 %; for polyps smaller than 1 cm the sensitivity was about 25 %. The overall sensitivity for all polyps was 40 %. Most people are more willing to accept non-invasive preventive medical check-ups. Therefore, the measurement of Tumor M2-PK in stool samples, with follow-up by colonoscopy to clarify the Tumor M2-PK positive results, may prove to be an advance in the early detection of colorectal carcinomas. More research is needed before the test can be recommended as a screening procedure. [edit]Tumor M2-PK measurements in cancer follow-up Studies from various international working groups have revealed a significantly increased amount of Tumor M2-PK in EDTA-plasma samples of patients with renal, lung, breast, cervical and gastrointestinal tumors (oesophagus, stomach, pancreas, colon, rectum), as well as melanoma (= skin cancer), which correlated with the tumor stage. The combination of Tumor M2-PK with the appropriate classical tumor marker, such as CEA for bowel cancer, CA 19-9 for pancreatic cancer and CA 72-4 for gastric cancer, significantly increases the sensitivity to detect various cancers. An important application of the Tumor M2-PK test in EDTA-plasma is for follow-up during tumor therapy, to monitor the success or failure of the chosen treatment, as well as predicting the chances of a “cure” and survival. If Tumor M2-PK levels decrease during therapy and then remain low after therapy it points towards successful treatment. An increase in the Tumor M2-PK values during or after therapy points towards relapse and/or metastasis. Increased Tumor M2-PK values can sometimes also occur in severe inflammatory diseases, which must be excluded by differential diagnosis. & www.nature.com/bjc/journal/v96/n9/full/6603712a.html Odpowiedz Link
