Method for monitoring and prognosis of disease course of gastrointestinal tumors
The present invention provides a method for diagnosis, monitoring and prognosticating the disease course of gastrointestinal tumors, comprising determining the level of a cyclin dependent kinase inhibitor (CK1) in a sample and diagnosing the disease and/or recurrence of the disease or prognosticating the disease course from the level of said CK1 in the examined tumor cells. Furthermore the present invention provides a method for tailoring a suitable therapy for gastrointestinal tumors. Another aspect of the present invention are test kits for research and diagnostic purposes.
1. A method for prognosticating the survival rate of an individual having lymph node-negative gastric cancer comprising detecting the protein expression level of cyclin-dependent kinase inhibitor p16 in a gastric cancer biopsy sample obtained from the individual, wherein the overexpression of the cyclin-dependent kinase inhibitor p16 is correlated with the prognosis of reduced survival rate of the individual.
2. The method of claim 1 , wherein the sample is coupled covalently or non-covalently or adhere to a solid.
3. The method of claim 1 , wherein the detection of the protein expression level is carried out by means of an antibody specific for the cyclin-dependent kinase inhibitor p16.
