Abstract:
4079 Background: Perioperative ECF is a standard treatment for localized gastric/OGJ adenocarcinoma. However, 5-year survival rate remains below 40%. The FLOT regimen is an effective combination with pathologic response rates in the 15% range. This phase III study compares both regimens in resectable stages. Methods: Pts are stratified by different baseline criteria and randomized to either 3 + 3 perioperative cycles of ECF (epirubicin 50 mg/m 2 , d1; cisplatin 60 mg/m², d1; 5-FU 200 mg/m², d1-d21, qd21) or 4 + 4 cycles of perioperative FLOT (docetaxel 50mg/m 2 , d1; 5-FU 2600 mg/m², d1; leucovorin 200 mg/m², d1; oxaliplatin 85 mg/m², d1, qd14). 5-FU can be replaced by capecitabine in the ECF-arm (ECX). Central pathology is performed. This is a preplanned safety analysis after 300 patients. Results: The ongoing studyhas enrolled 380 of planned 590 pts, so far. 305 pts were included in this analysis. Median age is 62 yrs; 78% of pts are male. The primaries were gastric in 44.9%, OGJ in 50.4% and not evaluable/documented in 4.7% of pts. 281 pts were eligible for safety analyses. Median no. of preoperative cycles was 3 and 4 with ECF/ECX and FLOT, respectively, 35.9% vs. 44.6% of pts (ECF/ECX vs. FLOT) started postoperative chemotherapy (ct) and 22.5% vs 33.1% received all planned cycles. Grade 3/4 neutropenia was observed in 28.0% of ECF/ECX and 45.3% of FLOT pts (p=.0026). Thromboembolic events occurred in 14.1% vs. 5.8% in pts with ECF/ECX vs. FLOT (p=.027). Serious adverse events occurred in 52.1% vs. 47.5% of pts with ECF/ECX vs. FLOT (p=.48). Preoperative delay/interruptions of ct were observed in 71.1% vs. 56.8% of pts with ECF/ECX vs. FLOT (p=.013). Dose modifications of preoperative ct were performed in 27.5% vs. 20.1% of treatment cycles with ECF/ECX vs. FLOT, respectively. 197 pts have undergone surgery so far. Severe surgical morbidity was similar in both arms (ECF/ECX, 19.8%; FLOT, 16.8%). Surgical mortality was observed in 4 and 2 pts with ECF/ECX and FLOT. Toxic deaths were observed in 1 pt each. Conclusions: Perioperative FLOT is feasible and safe. Clinical trial information: NCT01216644.
