Abstract
PURPOSE
Tumor-associated serum markers have demonstrated predictive and prognostic value in patients being treated for malignancies. However, the clinical importance of tumor markers in gastric cancers (GC) is poorly standardized.
OBJECTIVES
The objective is to assess the clinical utility of cytokeratin-19 fragment (CYFRA 21-1) and carcinoembryonic antigen (CEA) as serum tumor markers in advanced GC.
METHODS
In this prospective study, CYFRA 21-1 and CEA levels were measured at baseline and after three cycles of chemotherapy in patients with advanced GC. The association of tumor marker levels with prognosis and decline of tumor markers with radiological overall response rates (ORR) and survival were analyzed.
RESULTS
In the 105 patients, the proportion of patients with elevated baseline CYFRA 21-1 and CEA levels was 55% (N = 58) and 37% (N = 39) based on predefined cutoffs. Response assessment was done for 61 patients who received a minimum of three cycles of chemotherapy. A 15% and 13% reduction of serum levels from baseline for CYFRA 21-1 and CEA were selected for defining "CYFRA 21-1 response" and "CEA-response," respectively. Both responses were significant predictors of radiological ORR. The median overall survival (OS) was 9.6 months in the entire cohort and 13 months for patients who received at least three cycles of chemotherapy. In multivariate analysis, baseline CEA levels and ECOG status were significant predictors of OS. In a subset analysis of patients receiving palliative chemotherapy, any of the tumor marker responses predicted improved 1-year OS.
CONCLUSION
In advanced GC, CYFRA 21-1 and CEA decline from baseline appeared to be reliable surrogate markers of chemotherapy efficacy and improved survival.
