Survival of GEJ and gastric adenocarcinoma patients admitted at Imam Khomeini and Aram oncology clinic and treated with preoperative EOX chemotherapy

Objective: We aimed to investigate safety and efficacy of preoperative chemotherapy using EOX regime in patients with locally advanced gastric and GEJ cancer who were admitted at Imam-Khomeini Oncology clinic and Aram clinic. Method: We performed a mix-cohort study in 51 gastric cancer patients. In the beginning, we performed contrast thorax and abdominal CT scan or ECO cardiograph to determine cancer staging. After that, each patient received 3-weeks EOX regime in 6 cycle. After each three cycles follow-up CT scan was performed to assess any possible progression. Response to the treatment, Overall survival, and Progression-Free Survival were the main outcomes that we evaluated in the current study. We used Kaplan-Meier approach and Cox regression to address survival rate and its prognostic factors. Results: Overall, 72.5% percent were male and mean age of study participants was 57.6. Complete response rate was observed in 11.1%, while 51.1% showed partial response. Median of overall survival and Progression-Free Survival was estimated 35.0 and 28.0 month, respectively. The 5-year overall survival was 74.2% and for PFS it was estimated at 57.7%. Conclusion: Preoperative chemotherapy using EOX regime could increase survival rate among patients with gastric and GEJ cancer.
