Problems solved by technology

At present, there are no sufficiently sensitive and specific predictors to predict the recurrence and survival of patients with liver cancer after surgery. Although alpha-fetoprotein, tumor size, and presence or absence of capsules are related to metastasis and recurrence, their prediction accuracy is overall. It is still very low, especially for the postoperative recurrence of early liver cancer, it is even more unpredictable

Abstract

The invention provides a multimolecular prediction kit for postoperative recurrence and transfer for the patients with liver cancer based on inflammatory factor, characterized by comprising a coating agent, a washing liquid, a horseradish peroxidase-labeled antibody, a substrate solution, a stop solution, and prediction reference values, wherein, the coating agent is composed of a carbonate coating buffer solution of PH9.6, and an interleukin 2 antibody or an interleukin 15 antibody or an interleukin 5 antibody; based on the 4mug / mul of protein concentration of extract from liver peri-cancer tissue, the prediction reference values of interleukin 2, interleukin 15, and interleukin 5 are respectively 20-30pg / ml, 32-43pg / ml, and 18-28pg / ml, and the prediction reference values vary proportionably along with the sample concentration. In the invention, by using the interleukin 2, interleukin 15, and interleukin 5 in liver peri-cancer tissue, the postoperative recurrence and transfer for the patients with liver cancer can be accurately predicted.

Description

technical field [0001] The invention relates to a multi-molecule prediction kit for postoperative metastasis and recurrence of liver cancer patients based on inflammatory factors, which belongs to the field of biotechnology. Background technique [0002] Liver cancer is the second leading cause of cancer death in my country, and surgery is currently the main treatment. However, the high postoperative recurrence rate of metastasis (5-year recurrence rate reaches 70%, small liver cancer also reaches 50%) has become a bottleneck for further improving long-term efficacy, and is also an important key to conquer liver cancer. If it is possible to predict the early metastasis and recurrence of specific groups after radical resection of liver cancer, and to provide timely intervention and treatment, so as to achieve early detection and early treatment, the survival rate of patients with recurrence after radical resection will be further improved, and there will also be great social ...
