Researchers Submit Patent Application, "Method And Kit For Assisting In Determination Of Malignant Pancreatic Cystic Tumor", for Approval (USPTO 20240168026).

Researchers from Toray Industries Inc. have developed a noninvasive method and kit to determine whether pancreatic cystic tumors are malignant or benign. The method involves measuring the amounts of two APOA2 protein variants in a body fluid sample obtained from the patient. The researchers found that the concentration of the APOA2-AT protein is lower in malignant tumors compared to benign ones, while the concentration of the APOA2-ATQ protein is higher. This patent application describes a convenient and noninvasive way to determine the nature of pancreatic cystic tumors. [Extracted from the article]
