Cytological examination can be used for the diagnosis of gallbladder cancer

Among the malignant tumors of the gallbladder, gallbladder cancer ranks first, which shows the harm it brings to people. The diagnostic examination methods of gallbladder cancer include CT scan, cytology examination, tumor markers, etc. Today, experts will introduce the diagnostic examination of gallbladder cancer based on these three examination methods.

1. CT scan: The sensitivity of CT scan for gallbladder cancer is 50%, especially for the diagnosis of early gallbladder cancer, which is not as good as other methods. It can be divided into three types: wall thick type, nodular type, and solid type. If the tumor invades the liver or the hepatic hilum and pancreatic head lymph nodes, it can often be shown under CT images.

2. Cytological examination: Cytological examination includes direct biopsy or bile extraction to search for cancer cells. There are two direct biopsy methods: gallbladder lesion puncture under B-ultrasound guidance PTCCS (percutaneous cholecystoscopy) through laparoscopy and other methods. There are more methods of taking bile, such as bile extraction under ERCP, gallbladder puncture under B-ultrasound guidance PTCD choledochoscopy, etc. Although the positive rate of cytological examination reported in the literature is not high, it can still be combined with imaging examination methods to diagnose more than half of gallbladder cancer patients.

3. Tumor markers: In the report of CEA immunohistochemistry research on tumor specimens, the CEA positivity rate of gallbladder cancer is 100%. The serum CEA value of patients with advanced gallbladder cancer can reach 9.6ng/ml, but it is worthless in early diagnosis. CA19-9CA125CA15-3, etc. Tumor sugar chain antigens can only be used as auxiliary diagnostic tests for gallbladder cancer.
