- Esophagectomy is a complex and complication laden procedure. Despite centralization, variations in perioparative strategies reflect a paucity of evidence regarding optimal routines. The use of nasogastric (NG) tubes post esophagectomy is typically associated with significant discomfort for the patients. We hypothesize that immediate postoperative removal of the NG tube is non-inferior to current routines. All Nordic Upper Gastrointestinal Cancer centers were invited to participate in this open-label pragmatic randomized controlled trial (RCT). Inclusion criteria include resection for locally advanced esophageal cancer with gastric tube reconstruction. A pretrial survey was undertaken and was the foundation for a consensus process resulting in the Kinetic trial, an RCT allocating patients to either no use of a NG tube (intervention) or 5 days of postoperative NG tube use (control) with anastomotic leakage as primary endpoint. Secondary endpoints include pulmonary complications, overall complications, length of stay, health related quality of life. A sample size of 450 patients is planned (Kinetic trial: https://www.isrctn.com/ISRCTN39935085). Thirteen Nordic centers with a combined catchment area of 17 million inhabitants have entered the trial and ethical approval was granted in Sweden, Norway, Finland, and Denmark. All centers routinely use NG tube and all but one center use total or hybrid minimally invasive-surgical approach. Inclusion began in January 2022 and the first annual safety board assessment has deemed the trial safe and recommended continuation. We have launched the first adequately powered multi-center pragmatic controlled randomized clinical trial regarding NG tube use after esophagectomy with gastric conduit reconstruction.

- OBJECTIVE: To investigate if prolonged TTS after completed nCRT improves postoperative outcomes for esophageal and esophagogastric junction cancer.SUMMARY OF BACKGROUND DATA: TTS has traditionally been 4-6 weeks after completed nCRT. However, the optimal timing is not known.METHODS: A multicenter clinical trial was performed with randomized allocation of TTS of 4-6 or 10-12 weeks. The primary endpoint of this sub-study was overall postoperative complications defined as Clavien-Dindo grade II-V. Secondary endpoints included complication severity according to Clavien-Dindo grade IIIb-V, postoperative 90-day mortality, and length of hospital stay. The study was registered in Clinicaltrials.gov (NCT02415101).RESULTS: In total 249 patients were randomized. There were no significant differences between standard TTS and prolonged TTS with regard to overall incidence of complications Clavien-Dindo grade II-V (63.2% vs 72.6%, P = 0.134) or regarding Clavien-Dindo grade IIIb-V complications (31.6% vs 34.9%, P = 0.603). There were no statistically significant differences between standard and prolonged TTS regarding anastomotic leak (P = 0.596), conduit necrosis (P = 0.524), chyle leak (P = 0.427), pneumonia (P = 0.548), and respiratory failure (P = 0.723). In the standard TTS arm 5 patients (4.3%) died within 90 days of surgery, compared to 4 patients (3.8%) in the prolonged TTS arm (P = 1.0). Median length of hospital stay was 15 days in the standard TTS arm and 17 days in the prolonged TTS arm (P = 0.234).CONCLUSION: The timing of surgery after completed nCRT for carcinoma of the esophagus or esophagogastric junction, is not of major importance with regard to short-term postoperative outcomes.

- Purpose: Curative treatment of esophageal cancer is accompanied by frequent and sometimes severe side effects. However, prospectively collected data on side effects are scarce. The aim of this study was to evaluate if pulmonary function and exercise capacity were affected in the acute setting after neoadjuvant treatment and if there were long-lasting effects after neoadjuvant treatment and surgery. We also aimed to investigate whether the addition of radiation therapy to chemotherapy would aggravate side effects. Methods and materials: A cohort of 97 patients enrolled in the randomized NeoRes trial was used for the present analysis. The patients had been randomized to receive 3 cycles of cisplatin and fluorouracil with or without concurrent radiation therapy to 40 Gy. A cardiac stress test on a stationary bicycle and a spirometry were performed before and after neoadjuvant treatment and 1 to 2 years later after surgery provided that the cancer had not recurred. Results: We found impairment in pulmonary function measured as vital capacity and forced expiratory volume in 1 second and a decrease in exercise capacity after neoadjuvant treatment and 1 to 2 years later after surgery. We did not detect any differences between patients treated with chemoradiation therapy and those treated with chemotherapy alone. Conclusions: Multimodality treatment of esophageal cancer caused short-term and lasting impairments in pulmonary function and exercise capacity. The reductions were not aggravated by the addition of radiation therapy to neoadjuvant chemotherapy.
