Abstract
BACKGROUND: Patients with resectable oesophageal cancer are treated with neoadjuvant chemoradiotherapy (nCRT) followed by surgery within 3-8 weeks. In practice, surgery is often delayed for various reasons. The aim of this study was to evaluate whether delaying surgery beyond 8 weeks has an effect on postoperative morbidity, long-term survival, and pathologic response in patients treated for oesophageal ADC. METHODS: Patients who underwent nCRT followed by surgery, for cT1-3, N0-3, M0 ADC between 2001 and 2014 were retrospectively included from a prospectively obtained database. Patients with a time from the end of nCRT to surgery (TTS) ≤8 weeks were compared with patients with a TTS >8 weeks. RESULTS: Of 190 patients, 65 had a TTS ≤8 weeks, and 125 had a TTS >8 weeks. Patient characteristics were comparable for both groups, but patients with TTS >8 weeks exhibited higher ASA scores (p = 0.013) and more comorbidities (p = 0.007). Multivariate analysis revealed that TTS did not significantly influence postoperative morbidity, pathologic complete response rates, and five-year survival rates (42% in patients with TTS ≤8 weeks and 37% in patients with TTS >8 weeks). CONCLUSIONS: Delaying surgery beyond 8 weeks after nCRT did not significantly influence postoperative morbidity, pathologic response, and survival in patients with non-metastatic ADC. Therefore, it appears reasonable to postpone surgery beyond 8 weeks in patients who have not yet recovered from nCRT. However, if the patient is fit for surgery, postponing surgery does not have any additional advantages.
