Brief summary
Patients with resectable adenocarcinoma of stomach or esophagogastric junction without previous therapy will be treated with one of two chemotherapy regimens perioperatively. One group of the patients will receive 5-Fluorouracil (5-FU), Leucovorin, Oxaliplatin and Docetaxel (FLOT), the second group will receive Oxaliplatin and Capecitabin (XELOX). Primary endpoint of the study is the proportion of patients who complete all allocated treatment.
Detailed description
328 рatients with resectable (T1b-4 and/or N-/+, M0) adenocarcinoma of the stomach or the esophagogastric junction without previous therapy will be included in this study. After staging laparocopy patients will be randomized to receive preoperatively 4 cycles FLOT or 4 cycles XELOX followed by curative surgery. Adjuvant chemotherapy will be given as 4 cycles of FLOT or 4 cycles XELOX. The primary endpoint is the proportion of patients who fully adhered to all the allocated treatment per protocol. Secondary endpoints are pathological regression grade, progression free survival, overall survival, chemotherapy and surgery complications rates.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Proportion of patients who complete all the treatment per protocol | Up to 2 months | Completed treatment protocol is considered as 4 cycles neoadjuvant chemotherapy followed by curative surgery and 4 cycles of adjuvant chemotherapy. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Histopathological regression rate (Becker regression criteria) | 2 weeks after surgery | To determine histopathological regression rate after FLOT regimen compared to XELOX regimen in neoadjuvant settings |
| Chemotherapy toxicity profile | at the end of XELOX cycle (each cycle is 21 days) and FLOT cycle (each cycle is 14 days) | To determine and compare toxicity profile in patients receiving XELOX or FLOT regimen |
| Median overall survival | 5 year follow up after the last cycle of chemotherapy | To determine the efficacy of FLOT regimen compared to XELOX regimen by assessment of overall survival |
| 1-year disease-free survival rate | 1 year after surgery | To determine the efficacy of FLOT regimen compared to XELOX regimen during the first year after the surgery |
| Correlation between histopathological regression and disease-free survival | 2 years of follow-up after the last cycle of chemotherapy | To determine correlation between histopathological regression and disease-free survival in different chemotherapeutic settings |
| Surgical complications rate | up to 90th day after surgery | To determine surgical complication rate and profile after different types of regimens in neoadjuvant settings |
