Abstract

The present application relates to the use of tumor-derived IgG in the diagnosis or prognosis of pancreatic cancer. This application discloses the application of a monoclonal antibody that specifically recognizes the constant region of the heavy chain of human tumor-derived immunoglobulin G (CIgG), which is characterized in that: using immunohistochemistry or immunofluorescence techniques, the pathological score of antibody staining is used to determine whether the pancreatic The degree of pathological differentiation of cancer and the prognosis of patients and the preparation of an immunohistochemical kit for detecting the degree of differentiation of pancreatic cancer and evaluating the prognosis. The technical solution of the present application has important application value for improving the accuracy of pancreatic cancer prognosis assessment in clinical and scientific research work, and provides a basis for individualized diagnosis and treatment of tumors.

Description

technical field

[0001] This application relates to the field of medicine. Specifically, it relates to the fields of clinical diagnosis and prognosis. The present application relates to the use of tumor-derived IgG as a prognostic marker for pancreatic tumors. Background technique

[0002] Pancreatic cancer is still one of the malignant tumors with the highest mortality rate. The incidence of pancreatic cancer is increasing year by year, but its five-year survival rate is still less than 10%. Relevant literature predicts that pancreatic cancer will become the second malignant tumor in tumor-related mortality within 10 years[1-2]. A number of clinicopathological indicators have been used to evaluate the prognosis of pancreatic cancer patients, including tumor pathological grade, lymph node metastasis, CA19-9 level, etc. [3-5]; some molecular markers, such as Ki-67, mTOR pathway molecules, hedgehog Pathway molecules, etc., have also been applied to the prognosis of pancreati...
