    Abstract: Chest wall pain following a thoracotomy for esophageal cancer is frequently reported but poorly understood. The aims of this study were 1) to determine the prevalence of chest wall abnormalities on postoperative imaging; and 2) to compare complications, long-term pain, and quality of life in patients with versus without thoracotomy-related thoracic fractures. Methods This retrospective cohort study enrolled patients with esophageal cancer who underwent a thoracotomy between 1 January 2010 and 31 December 2020. An early postoperative CT ( & lt;1 month) and/or late CT ( & gt;6 months) had to be available. Disease-free patients were asked to complete questionnaires on pain and quality of life (SF-36 and EORTC-QLQ-C30). Results A total of 366 patients were included. Thoracotomy-related rib fractures were seen in 144 (39%) patients and thoracic transverse process fractures in 4 (2%). Patients with thoracic fractures more often developed postoperative complications (89% versus 74%, p = 0.002), especially pneumonia (51% versus 39%, p = 0.032). Seventy-seven participants (33 with thoracic fractures, 44 without) completed questionnaires median 41 (P25-P75 28–91) months postoperatively. Long-term chest wall pain was reported by 48 (63%) participants but no association with thoracic fractures was found (p = 0.637). Quality of life scores did not differ between patients with versus without thoracic fractures and were mostly comparable with their reference populations. Conclusions Thoracic (mainly rib) fractures are prevalent following a thoracotomy for esophageal cancer. Patients with thoracic fractures have an increased risk of postoperative complications, especially pneumonia, but an association with long-term pain or decreased quality of life was not confirmed.

    Abstract: An optimal model for predicting pathologic response after neoadjuvant chemoradiotherapy (nCRT) in oesophageal cancer has not been defined yet. FDG-PET/CT is frequently used in response assessments. The aim of this side study of the preSANO trial (NL41732.078.13) was to investigate if the FDG-PET parameters SUVmax, total lesion glycolysis (TLG) and metabolic tumour volume (MTV) were predictive for residual tumour in the resected specimen of oesophageal cancer patients treated with nCRT. Methods Patients underwent FDG-PET/CT at baseline according to the European Association of Nuclear Medicine guidelines 1.0 (2.3MBq/kg F-18-FDG; scanning 60 ± 5min.). All parameters were corrected for lean body mass. MTV was defined as the volume within a 41% of SULmax ( = SUV/lean body mass) isocontour threshold at tumour and lymph nodes. TLG was calculated as SULmean x MTV. Logarithmic transformation was performed because of non-normal distribution of TLG and MTV. Baseline PET parameters were compared to tumour regression grade in the resection specimen (TRG3–4 =  〉  10% residual tumour vs. TRG1 = complete response). Peroperatively irresectable tumours were recoded as TRG4. Analyses were performed using an independent-samples T-test. Results From a total of 207 patients who underwent FDG-PET/CT before nCRT, 197 were included for analysis (5 were non-FDG avid, 5 had incomplete data). Histological type of tumour: adenocarcinoma (AC) n = 154, squamous cell carcinoma (SCC) n = 42, and one adenosquamous carcinoma. Thirty-seven patients (19%) had TRG1 and 41 patients (21%) had TRG3–4. In complete responders (TRG1), SULmax, TLG and MTV (mean ± SD) were 9.6 ± 5.8, 85.3 ± 85.5 and 13.0 ± 9.9, respectively. In patients with TRG3–4, SULmax, TLG and MTV were 9.4 ± 5.4145.8 ± 164.6 and 21.9 ± 16.2, respectively. SULmax was not significantly different between both groups (P = 0.8), but log(TLG) and log(MTV) (P = 0.008 and P = 0.001) were. In adenocarcinomas, log(TLG) did not differ between groups (P = 0.1). Conclusion Initial FDG tumour mass, expressed as MTV, (rather than SULmax) is the most contributing factor in predicting residual disease after nCRT in both SCC and AC. The effect is stronger in SCC. Therefore, baseline FDG tumour mass should be included in a prediction model, besides other clinical and tumour parameters. Disclosure All authors have declared no conflicts of interest.

    Abstract: Active surveillance is being investigated as an alternative to standard surgery after neoadjuvant chemoradiotherapy for oesophageal cancer. It is unknown whether dysphagia persists or develops when the oesophagus is preserved after neoadjuvant chemoradiotherapy. The aim of this study was to assess the prevalence and severity of dysphagia during active surveillance in patients with an ongoing response. Methods Patients who underwent active surveillance were identified from the Surgery As Needed for Oesophageal cancer (‘SANO’) trial. Patients without evidence of residual oesophageal cancer until at least 6 months after neoadjuvant chemoradiotherapy were included. Study endpoints were assessed at time points that patients were cancer-free and remained cancer-free for the next 4 months. Dysphagia scores were evaluated at 6, 9, 12, and 16 months after neoadjuvant chemoradiotherapy. Scores were based on the European Organisation for Research and Treatment of Cancer oesophago-gastric quality-of-life questionnaire 25 (EORTC QLQ-OG25) (range 0–100; no to severe dysphagia). The rate of patients with a (non-)traversable stenosis was determined based on all available endoscopy reports. Results In total, 131 patients were included, of whom 93 (71.0 per cent) had adenocarcinoma, 93 (71.0 per cent) had a cT3–4a tumour, and 33 (25.2 per cent) had a tumour circumference of greater than 75 per cent at endoscopy; 60.8 to 71.0 per cent of patients completed questionnaires per time point after neoadjuvant chemoradiotherapy. At all time points after neoadjuvant chemoradiotherapy, median dysphagia scores were 0 (interquartile range 0–0). Two patients (1.5 per cent) underwent an intervention for a stenosis: one underwent successful endoscopic dilatation; and the other patient required temporary tube feeding. Notably, these patients did not participate in questionnaires. Conclusion Dysphagia and clinically relevant stenosis are uncommon during active surveillance.

    Abstract: Neoadjuvant chemoradiotherapy (nCRT) induces a pathologically complete response in approximately 30% of patients with oesophageal cancer. To explore the possibility of safe postponement of surgery, accurate clinical response evaluations are needed to exclude residual disease. The present study aims to assess the value of F-18-FDG-PET/CT for the detection of residual tumour ( 〉  10% tumour cells = TRG3–4 vs. no vital cells = TRG1) or metastases after nCRT. Methods FDG-PET/CT at baseline and 12 weeks after nCRT was performed according to the European Association of Nuclear Medicine guidelines 1.0 (2.3MBq/kg F-18-FDG; scanning 60 ± 5min.) and the protocol of the preSANO study. Qualitative analysis included sensitive reading of presence of residual tumour and/or metastases. A lesion was considered FDG-positive, when any uptake in the lesion itself was above the adjacent oesophageal background uptake. Quantitatively, SUV/lean body mass (SUL) measurements at tumour, lymph nodes, oesophagus, liver and bloodpool were recorded and compared with pathology (resection specimen: gold standard). Results Some 129 of 207 patients with FDG-avid tumours at baseline proceeded to FDG-PET/CT at around 12 weeks after nCRT just before surgery. Forty-one of 129 patients had TRG3–4, of whom 6 were missed on FDG-PET/CT (15% false negative) with SULmax 2.07 ± 0.25, SUL-ratio tumour/oesophagus (SULR) 1.35 ± 0.14. Sensitivity for TRG2–3-4 vs. TRG1 was 57/71 (80%). SULmax and SULR of FDG-positives were 3.76 ± 1.33 and 1.82 ± 0.69 respectively, compared to SULmax 2.21 ± 0.42 and SULR 1.31 ± 0.22 in FDG-negatives. Distant metastases were detected in 18 of 190 (10%) patients. Of all patients with postponed surgery, 12 had ≥ 1 additional FDG-PET/CT during follow-up (25–49.7 weeks after nCRT). Eventually, 4 patients underwent surgery. Three of 4 had increased FDG-signal and TRG3–4; 1 patient had decreased FDG-signal and no tumour left (TRG1). Conclusion FDG-PET/CT at around 12 weeks after nCRT misses TRG3–4 tumours in 15% and detects residual TRG2–3-4 in 80%. Furthermore, PET-CT detects distant metastases in 10% of patients after nCRT. These data indicate that serial FDG-PET may become valuable in an active surveillance approach. Disclosure All authors have declared no conflicts of interest.

    Abstract: Large studies comparing totally minimally invasive oesophagectomy (TMIE) with laparoscopically assisted (hybrid) oesophagectomy are lacking. Although randomized trials have compared TMIE invasive with open oesophagectomy, daily clinical practice does not always resemble the results reported in such trials. The aim of the present study was to compare complications after totally minimally invasive, hybrid and open Ivor Lewis oesophagectomy in patients with oesophageal cancer. Methods The study was performed using data from the International Esodata Study Group registered between February 2015 and December 2019. The primary outcome was pneumonia, and secondary outcomes included the incidence and severity of anastomotic leakage, (major) complications, duration of hospital stay, escalation of care, and 90-day mortality. Data were analysed using multivariable multilevel models. Results Some 8640 patients were included between 2015 and 2019. Patients undergoing TMIE had a lower incidence of pneumonia than those having hybrid (10.9 versus 16.3 per cent; odds ratio (OR) 0.56, 95 per cent c.i. 0.40 to 0.80) or open (10.9 versus 17.4 per cent; OR 0.60, 0.42 to 0.84) oesophagectomy, and had a shorter hospital stay (median 10 (i.q.r. 8–16) days versus 14 (11–19) days (P = 0.041) and 11 (9–16) days (P = 0.027) respectively). The rate of anastomotic leakage was higher after TMIE than hybrid (15.1 versus 10.7 per cent; OR 1.47, 1.01 to 2.13) or open (15.1 versus 7.3 per cent; OR 1.73, 1.26 to 2.38) procedures. Conclusion Compared with hybrid and open Ivor Lewis oesophagectomy, TMIE resulted in a lower pneumonia rate, a shorter duration of hospital stay, but higher anastomotic leakage rates. Therefore, no clear advantage was seen for either TMIE, hybrid or open Ivor Lewis oesophagectomy when performed in daily clinical practice.

    Abstract: Patients with different ethnic and genetic backgrounds may respond differently to anticancer therapies. This study aimed to assess whether patients with oesophageal squamous cell carcinoma (OSCC) treated with neoadjuvant chemoradiotherapy (nCRT) in East Asia had an inferior pathological response compared with patients treated in Northwest Europe. Methods Patients with OSCC who underwent nCRT according to the CROSS regimen (carboplatin and paclitaxel with concurrent 41.4 Gy radiotherapy) followed by oesophagectomy between June 2012 and April 2020 were identified from East Asian and Dutch databases. The primary outcome was pCR, defined as ypT0 N0. Groups were compared using propensity score matching, adjusting for sex, Charlson Co-morbidity Index score, tumour location, cT and cN categories, interval between nCRT and surgery, and number of resected lymph nodes. Results Of 725 patients identified, 133 remained in each group after matching. A pCR was achieved in 37 patients (27.8 per cent) in the Asian database and 58 (43.6 per cent) in the Dutch database (P = 0.010). The rate of ypT1–4 was higher in Asian than Dutch data (66.2 and 49.6 per cent; P = 0.004). The ypN1–3 rate was 44.4 per cent in the Asian and 33.1 per cent in the Dutch data set. Clear margins were achieved in 92.5 per cent of Asian and 95.5 per cent of Dutch patients. Conclusion Regional differences in responses to CROSS nCRT for oesophageal cancer were apparent, the origin of which will need evaluation.

    Abstract: Patients with cancer of the oesophagus or gastro-oesophageal junction have a high risk of recurrence after treatment with curative intent. The aim of this study was to analyse the site of recurrence, treatment, and survival in patients with recurrent disease. Methods Patients with non-metastatic oesophageal or junctional carcinoma treated with curative intent between January 2015 and December 2016 were selected from the Netherlands Cancer Registry. Data on recurrence were collected in the second half of 2019. Overall survival (OS) was assessed by Kaplan–Meier methods. Results In total, 862 of 1909 patients (45.2 per cent) for whom information on follow-up was available had disease recurrence, and 858 patients were included. Some 161 of 858 patients (18.8 per cent) had locoregional recurrence only, 415 (48.4 per cent) had distant recurrence only, and 282 (32.9 per cent) had combined locoregional and distant recurrence. In all, 518 of 858 patients (60.4 per cent) received best supportive care only and 315 (39.6 per cent) underwent tumour-directed therapy. Patients with locoregional recurrence alone more often received chemoradiotherapy than those with distant or combined locoregional and distant recurrence (19.3 per cent versus 0.7 and 2.8 per cent), and less often received systemic therapy (11.2 per cent versus 30.1 and 35.8 per cent). Median OS was 7.6, 4.2, and 3.3 months for patients with locoregional, distant, and combined locoregional and distant recurrence respectively (P & lt; 0.001). Conclusion Disease recurred after curative treatment in 45.2 per cent of patients. Locoregional recurrence developed in only 18.8 per cent. The vast majority of patients presented with distant or combined locoregional and distant recurrence, and received best supportive care.

    Abstract: After curatively intended neoadjuvant chemoradiotherapy (nCRT) according to CROSS plus surgery for esophageal cancer, 29% of patients have a pathologic complete response. Active surveillance after nCRT, in which patients undergo frequent clinical examinations and where esophagectomy is only offered to those with a locoregional regrowth without distant metastases, has been proposed as novel treatment option. This study provides a systematic review and meta-analysis of the literature regarding the accuracy of endoscopic biopsies, endoscopic ultrasound (EUS) and 18F-FDG PET(-CT) for detecting residual disease after nCRT for esophageal cancer. Methods A systematic literature search in Embase, Medline, Cochrane and Web of Science was performed. Two reviewers independently collected studies on the diagnostic accuracy of endoscopic biopsies, EUS and 18F-FDG PET(-CT) for detecting residual disease after nCRT at the primary tumor site or in regional lymph nodes for potentially curable esophageal adenocarcinoma (AC) or squamous cell carcinoma (SCC). Histopathological examination of the resection specimen was the reference standard. Study quality was appraised with the QUADAS-2 tool. Sensitivity and specificity values were calculated and pooled using meta-analyses. Subgroup analyses were performed to investigate possible sources of heterogeneity. Results 60 studies were included for qualitative analysis and 40 for quantitative analysis. For detecting residual disease at the primary tumor site, 11 studies evaluated endoscopic biopsies, 11 described EUS qualitatively, 14 evaluated PET qualitatively, 12 evaluated PET quantitatively, 6 of them using SUVmax and 6 of them using DSUVmax. Summary sensitivity values were 0.36 (95%CI 0.27–0.45), 0.97 (95%CI 0.94–0.98), 0.74 (95%CI 0.66–0.81), 0.68 (95%CI 0.61–0.74) and 0.68 (95%CI 0.54–0.79), respectively. Summary specificity values were 0.93 (95%CI 0.85–0.97), 0.09 (95%CI 0.04–0.19), 0.52 (95%CI 0.40–0.63), 0.70 (95%CI 0.61–0.78), 0.70 (95%CI 0.60–0.78) and respectively. For detecting residual malignant lymph nodes, 11 studies evaluated EUS with a summary sensitivity of 0.68 (95%CI 0.54–0.80) and a summary specificity of 0.58 (95%CI 0.45–0.70). Subgroup analyses demonstrated that sensitivity of endoscopic biopsy, PET DSUVmax and EUS for nodal was higher in SCC than in AC. Conclusion Current literature suggests insufficient accuracy of endoscopic biopsies, EUS and 18F-FDG PET(-CT) as individual modalities for detecting residual disease after nCRT for potentially curable esophageal cancer.

    Abstract: To compare complications following totally minimally invasive (TMIE), laparoscopically assisted (hybrid) and open Ivor Lewis esophagectomy in patients with esophageal cancer. Three randomized trials have reported benefits for minimally invasive esophagectomy. Two studies compared TMIE versus open esophagectomy and another compared hybrid versus open Ivor Lewis esophagectomy. Only small retrospective studies compared TMIE with hybrid Ivor Lewis esophagectomy. Methods Data were used from the International Esodata Study Group assessing patients undergoing TMIE, hybrid or open Ivor Lewis esophagectomy. Primary outcome was pneumonia, secondary outcomes included incidence and severity of anastomotic leakage, (major) complications, length of stay, escalation of care and 90-day mortality. Data were analyzed using multivariate multilevel models. Results In total, 4733 patients were included in this study (TMIE:1472, hybrid:1364 and open:1897). Patients undergoing TMIE had lower incidence of pneumonia compared to hybrid (10.9% vs 16.3%, Odds Ratio (OR):0.56, 95%CI: 0.40–0.80) and open esophagectomy (10.9% vs 17.4%, OR:0.60, 95%CI: 0.42–0.84) and had shorter length of stay (median 10 days (IQR 8–16)) compared to hybrid (14 (11–19), p = 0.041) and open esophagectomy (11 (9–16), p = 0.027). Patients undergoing TMIE had higher rate of anastomotic leakage compared to hybrid (15.1% vs 10.7%, OR:1.47, 95%CI: 1.01–2.13) and open esophagectomy (7.3%, OR:1.73, 95%CI: 1.26–2.38). No differences were reported between hybrid and open esophagectomy. Conclusion Compared to hybrid and open Ivor Lewis esophagectomy, TMIE resulted in a lower pneumonia rate, a shorter hospital length of stay but a higher anastomotic leakage rate. The impact of these individual complications on survival and long-term quality of life should be further investigated.
