Tumor Markers CEA, CA19-9 and CA125 in Monitoring of Response to Systemic Chemotherapy in Patients with Advanced Gastric Cancer

Abstract

The measurement of tumor markers might be useful in monitoring response and in predicting the prognosis of patients with advanced gastric cancer treated with systemic chemotherapy. Tumor markers may be used as a means of monitoring treatment in patients when in an imaging study it is difficult to assess response to chemotherapy in clinical practice. Further studies are required to confirm these findings.
