Design outcomes

Primary

MeasureTime frame
The feasibility of total neoadjuvant treatment for oesophageal adenocarcinoma compared to standard perioperative chemotherapy measured from Day 0 (randomisation) to the day of surgery. The primary endpoint is a binary endpoint called “treatment completion” and is either “yes” or “no”. It is defined differently in Arm A and Arm B. In Arm A patients need to complete six cycles of FLOT and have surgery. In Arm B, patients need to complete four cycles of FLOT and 90% of CROSS RT fractions and have surgery.

Secondary

MeasureTime frame
Tolerability of TNT in comparison to standard care, measured using the following from day 0 to week 26: 1. Number of completed FLOT cycles 2. Dose of FLOT components administered 3. Number of CROSS chemotherapy cycles administered 4. Dose of CROSS chemotherapy components administered 5. Number of CROSS RT fractions completed 6. Completion of four cycles of neoadjuvant FLOT in Arms B & C 7. Completion of eight cycles of neoadjuvant FLOT in Arm A 8. Completion of five cycles of neoadjuvant CROSS in Arm B 9. Commencement of postoperative FLOT in Arm C 10. Completion of four cycles of postoperative FLOT in Arm C Toxicity of TNT in comparison to standard care, measured using the following from day 0 to week 26: 1. Number of adverse events 2. Grade severity of AEs according to CTCAE v6.0 Pathological response of TNT in comparison to standard care, measured using the following at weeks 30-38: 1. Histopathological response according to Mandard criteria 2. Complete histopathological response rate 3. ypT status 4. ypN status (and number of LNs examined) 5. R0 status Surgical outcomes following TNT in comparison to standard care, measured using the following from day of surgery to 90 days postoperative: 1. Clavien-Dindo Grade 2 or higher surgical complication (including anastomotic leak, pneumonia, respiratory failure, cardiac ischaemia/arrhythmia, thrombus, intra-abdominal sepsis/collection, chyle leak) 2. Unplanned return to theatre 3. Unplanned admission to critical care 4. Unplanned hospital re-admission 30- and 90-day surgical mortality rate 5. Duration of hospital admission after surgery 6. Death (day of surgery to 30 and 90 days postoperative) Quality of life following TNT in comparison to standard care measured using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire scores (EORTC QLQ) -C30, EORTC QLQ-OG25, EORTC QLQ-OES18 at the following timepoints: Week 0 (pre-treatment initiation, first cycle of
