sCD8, as a Novel Biomarker for Pancreatic Cancer

August 11, 2022 updated by: Qiaofei Liu, Peking Union Medical College Hospital

The Diagnostic and Survival Predictive Value of Peripheral Serum Soluble CD58 (sCD5858) in Pancreatic Cancer Patients

Early detection and early treatment is the most important issue to improve the long-term survival of pancreatic cancer patients. CA199 is the most commonly used biomarker for early detection and to predict survival, however, the overall positive rate for CA199 is only 75%, and what is worse, for the early stage of pancreatic cancer patients, the positive rate is even lower, and for the lewis negative patients, CA199 is not produced at all. Therefore, novel biomarkers for the early detection of pancreatic cancer are still urgently needed. Previously, we found there is a vicious cycle between pancreatic cancer cells, that is pancreatic cancer-produced TGFbeta1 could promote the production of soluble CD58 (sCD58) in macrophages, and then sCD58 could induce the production of TGFbeta1 in pancreatic cancer cells. Therefore, the serum level of TGFbeta1 and sCD58 has diagnostic and survival values for pancreatic cancer.

Detailed Description

Pancreatic cancer is a highly malignant tumor with a very poor prognosis. The five-year survival rate is only 10%, and its incidence is significantly increasing worldwide. Early diagnosis and treatment can improve the survival of pancreatic cancer patients. However, the early diagnosis of pancreatic cancer is extremely difficult, and more than 50% of patients have distant metastasis at the time of diagnosis. Therefore, the development of sensitive and efficient serum biomarkers for pancreatic cancer has important clinical significance. Pancreatic cancer has a special microenvironment. Pancreatic cancer cells are only 10 to 30 percent, while inflammatory cells are more than 50 percent. The interaction between inflammatory cells and tumor cells promotes the development of pancreatic cancer. CD58 is an important immune adhesion molecule, which exists in the membrane (mCD58) and soluble (sCD58) states. For the first time, the investigators found that macrophages can promote CD58 expression separation in pancreatic cancer cells through TGFβ1, that is, the expression of mCD58 decreased and the release of more sCD58. SCD58 competitively binds CD2 on T/NK cells, thereby inducing immune suppression and promoting the development of pancreatic cancer. Therefore, the investigators propose a scientific hypothesis that serum sCD58 and TGFβ1 can be used as markers of tumor burden and tumor immunosuppression status in pancreatic cancer. They have important value in the diagnosis, immunotyping, and prognosis of pancreatic cancer. To test this scientific hypothesis, the investigators obtained peripheral blood serum from 132 healthy controls, 131 patients undergoing pancreatic cancer surgery, 80 patients with low-grade malignant pancreatic tumors, 58 patients with benign pancreatic tumors, and 16 patients with chronic pancreatitis as a training cohort. The expression levels of sCD58 and TGFβ1 in serum were detected by Elisa. The results showed that the expression levels of sCD58 and TGFβ1 in peripheral blood were significantly higher in pancreatic cancer, but there was no significant difference in sCD58 and TGFβ1 between other pancreatic diseases and healthy people. The expression levels of sCD58 and TGFβ1 were positively correlated with the clinical stage of pancreatic cancer. The level of sCD58 is negatively correlated with the prognosis of pancreatic cancer patients. The three-factor diagnostic model of sCD58, TGFβ1 and CA199 can improve the diagnostic efficiency of pancreatic cancer, especially when CA199 is disabled, sCD58 and TGFβ1 still have high diagnostic efficiency. However, this previous study still had the following shortcomings :(1) patients with advanced pancreatic cancer were not included; (2) The relationship between serum sCD58 and TGFβ1 and the efficacy of chemotherapy was not clarified. (3) The effects of immune diseases and infection on serum sCD58 and TGFβ1 were not considered; (4) The included sample size is small. Based on the previous study, this study plans to expand the sample size by 2 times as the validation cohort. The clinical value of serum sCD58 and TGFβ1 as biomarkers for diagnosis, immunotyping and prognosis prediction of pancreatic cancer was fully clarified by using pre-mature detection methods and modeling methods to improve the above four deficiencies. To develop a kit combining sCD58, TGFβ1 and CA199, improve the early diagnosis and treatment rate of pancreatic cancer, guide accurate immune typing and optimize individualized treatment, and finally prolong the survival time of patients.
