Discussion of difficult problems of early diagnosis of pancreatic cancer

Pancreatic cancer is a common malignant neoplasm of the pancreas with an extremely high mortality.Currently, the early diagnosis of pancreatic cancer is still not ideal.Attention should be paid to some clinical warning symptoms, such as unexplained abdominal and back pain, jaundice, and unexpected diabetes.Additionally, the combined use of CA19- 9, CEA, and other tumor markers, the attention to biochemical indicators, the detection of mutation in KAI1 or p53 gene, and the exploration of the value of miRNA in clinical diagnosis are of great significance.On the other hand, ultrasound, CT, MRCP, ERCP, PET- CT, and other imaging methods, as well as effective collection of cytology specimens, should be performed.Thus, there is hope for the early diagnosis of pancreatic cancer.
