Ca199 can be decreased in patients who have remission after chemotherapy for pancreatic cancer.
Ca199 is one of the tumor markers, which can be related to gastric cancer, colorectal cancer, pancreatic cancer and other diseases. For patients whose pancreatic cancer reaches clinical cure and some remission after chemotherapy, ca199 can drop to normal level.
If there is no effect after chemotherapy, ca119 may be maintained to the elevated level without decreasing to the normal level, and ca199 can be elevated again after clinical cure and tumor recurrence.
Therefore, CA199 can be used as one of the clinical tumor marker screening and can be used as one of the prognostic indicators. When the indicator is obviously abnormal, it should be actively diagnosed and treated.
