Abstract

© 2017 ABMSFBIH.Alpha-fetoprotein producing gastric carcinoma (AFP-PGC) is a rare cancer for which limited data on the clinicopathological features and treatment modalities exist. The aim of this study was to compare the efficacy of modified docetaxel-cisplatin-5-fluorouracil (mDCF) as the first-line chemotherapy regimen in metastatic AFP-PGC and non-AFP-PGC. The patients diagnosed with metastatic gastric cancer who were given mDCF as first-line therapy were retrospectively reviewed. The patients with a basal serum AFP level over 9 ng/ml were defined as AFP-PGC patients. In total, 169 patients (34 with AFP-PGC and 135 with non-AFP-PGC) were included in this study. AFP-PGC patients had more liver metastases than non-AFP-PGC patients (p < 0.001). A decrease in basal AFP levels after three cycles of chemotherapy was significantly different in AFP-PGC group (p = 0.001). Overall disease control rate was 79.4% (partial response [PR] - 44.1%, stable disease [SD] - 35.3%), and 82.2% (com-plete response - 3%, PR - 36.2%, SD - 43%) in AFP-PGC and non-AFP-PGC patients, respectively. There was no difference between AFP-PGC and non-AFP-PGC groups in overall and progression-free survival rates (11.3 versus 11.4 months and 7.7 versus 7.1 months, respectively). Rates of grade 3-4 hematologic toxicity were 8.8% and 6.7% for neutropenia in AFP-PGC and non-AFP-PGC group, respectively and 5.9% and 7.4% for anemia. In conclusion, mDCF regimen is well-tolerated with acceptable toxicity outcomes in both AFP-PGC and non-AFP-PGC patients. A statistically significant decrease in AFP levels after mDCF regimen indicate that AFP might be considered as a supplemental marker of response to mDCF chemotherapy in AFP-PGC patients. However, further prospective clinical trials are required in this area.
