Brief Summary
|
Gallbladder carcinoma (GBC) is the most common type of biliary tract cancer associated with poor outcome, especially when detected at an advanced stage. Owing to their aggressive behavior, even after surgery meant to completely remove the tumor and additional treatments like chemotherapy or radiation, this cancer often comes back. Timely detection of cancer recurrence is important because it allows consideration of second-line treatment, which can help control the disease, relieve symptoms, and possibly extend survival compared to only providing comfort care. Regular check-ups and follow-ups are key to early detection of recurrence. One possible tool for detecting recurrence is a blood test that measures carbohydrate antigen 19-9 (CA 19-9) – a substance that can be higher in people with gall bladder or pancreatic cancer. Although this test is widely used for surveillance in pancreatic cancer, its role in GBC surveillance is not yet well established. The present study looks at whether serial monitoring of serum CA 19-9 helps early detection of recurrence in GBC who underwent curative radical resection. |
