Background/Aims: Early detection of gallbladder (GB) cancer is essential for better survival rates. Most cases of GB cancer are diagnosed incidentally via pathology of the cholecystectomy specimen. Data on the clinical characteristics of early GB cancer are lacking. The aim of the current study was to investigate the clinical characteristics of early GB cancer to aid earlier diagnosis.
Methods: Sixty-four patients who were diagnosed with early GB cancer after surgical resection at the Samsung Medical Center were enrolled in this study. Clinical characteristics, preoperative diagnoses, preoperative tumor size, laboratory findings including carbohydrate antigen 19-9 (CA19-9) levels, imaging features, and survival rate were investigated.
Results: Clinical symptoms and serum tumor markers such as carcinoembryonic antigen and CA19-9 levels were not helpful indicators of early GB cancer. Radiologic modalities showed abnormal findings in every case of early GB cancer; a polypoid mass was the most common feature. Less common features included GB wall thickening, cholecystitis, and GB stones. The clinical outcome of early GB cancer was excellent.
Conclusions: Screening with imaging modalities such as computed tomography (CT) or ultrasonography (US) is helpful in detecting early GB cancer. Even in the presence of GB wall thickening, cholecystitis, or GB stones on the CT or US, any abnormal findings should prompt careful examination and intensive follow up, considering the possibility of occult gallbladder cancer.
