Minimally Invasive transCervical oEsophagectomy (MICE) for oesophageal cancer: prospective cohort study (IDEAL stage 2A).

BACKGROUND: Minimally invasive transcervical oesophagectomy is a surgical technique that offers radical oesophagectomy without the need for transthoracic access. The aim of this study was to evaluate the safety and feasibility of the minimally invasive transcervical oesophagectomy procedure and to report the refinement of this technique in a Western cohort. METHODS: A single-centre prospective cohort study was designed as an IDEAL stage 2A study. Patients with oesophageal cancer (cT1b-4a N0-3 M0) who were scheduled for oesophagectomy with curative intent were eligible for inclusion in the study. The main outcome parameter was the postoperative pulmonary complication rate and the secondary outcomes were the anastomotic leakage, recurrent laryngeal nerve palsy, and R0 resection rates, as well as the lymph node yield. RESULTS: In total, 75 patients underwent minimally invasive transcervical oesophagectomy between January 2021 and November 2023. Several modifications to the surgical technique were registered, evaluated, and implemented in the context of IDEAL stage 2A. A total of 12 patients (16%) had postoperative pulmonary complications, including pneumonia (4 patients) and pleural effusion with drainage or aspiration (8 patients). Recurrent laryngeal nerve palsy was observed in 33 of 75 patients (44%), with recovery in 30 of 33 patients (91%). A total of 5 of 75 patients (7%) had anastomotic leakage. The median number of resected lymph nodes was 29 (interquartile range 22-37) and the R0 resection rate was 96% (72 patients). CONCLUSION: Introducing minimally invasive transcervical oesophagectomy for oesophageal cancer in a Dutch institution is associated with a low rate of postoperative pulmonary complications and a high rate of temporary recurrent laryngeal nerve palsy.

Value of routine follow-up for recurrence detection after treatment with curative intent for laryngeal squamous cell carcinoma.

INTRODUCTION: The benefits of routine follow-up after treatment of primary laryngeal squamous cell carcinoma (LSCC) remain disputed. Guidelines worldwide are consensus-based, and evidence for specific subgroups is lacking. This study evaluates routine LSCC follow-up including flexible endoscopy for detecting locoregional recurrence (LRR). METHODS: A retrospective cohort of 413 LSCC patients treated between 2006 and 2012 was analysed. The cumulative risk of LRR was calculated. Routine follow-up was evaluated by follow-up visit (routine or interval) at which LRR was detected, LRR treatment intent, and overall survival (OS). Analyses were stratified by early (I-II) and advanced (III-IV) TNM-stage. RESULTS: There were 263 (64 %) patients with early-stage and 132 (32 %) patients with advanced-stage LSCC. One-, two- and five-year cumulative risks for LRR after early-stage LSCC were 8 %, 18 %, and 26 %. For advanced-stage LSCC, cumulative risks of LRR were 20 %, 30 %, and 35 %. Of all 69 LRRs after early-stage LSCC, 72 % were routine-detected, 81 % were symptomatic, and 90 % received curative-intent treatment. Of all 45 LRRs following advanced-stage LSCC, 42 % were routine-detected, 84 % were symptomatic, and 62 % received curative-intent treatment. Five-year OS of early-stage LSCC with routine-detected LRR was 70 %, and 72 % for interval-detection (log-rank-p = 0.91). Five-year OS of advanced-stage LSCC with routine-detected LRR was 37 %, and 18 % for interval-detection (log-rank-p = 0.06). CONCLUSIONS: Routine follow-up for detecting asymptomatic recurrences seems redundant for early-stage LSCC. After advanced-stage LSCC, no asymptomatic recurrences were detected beyond one year posttreatment despite regular follow-up. Emphasis should be on other follow-up aspects, such as psychosocial support, especially after one year posttreatment.
