Impact of 18FFDG-PET/CT and Laparoscopy in Staging of Locally Advanced Gastric Cancer: A Cost Analysis in the Prospective Multicenter PLASTIC-Study. Ann Surg Oncol 2024; 31:4005-4017. [PMID: 38526832 PMCID: PMC11076388 DOI: 10.1245/s10434-024-15103-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Accepted: 02/12/2024] [Indexed: 03/27/2024]
Abstract
BACKGROUND Unnecessary D2-gastrectomy and associated costs can be prevented after detecting non-curable gastric cancer, but impact of staging on treatment costs is unclear. This study determined the cost impact of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18FFDG-PET/CT) and staging laparoscopy (SL) in gastric cancer staging. MATERIALS AND METHODS In this cost analysis, four staging strategies were modeled in a decision tree: (1) 18FFDG-PET/CT first, then SL, (2) SL only, (3) 18FFDG-PET/CT only, and (4) neither SL nor 18FFDG-PET/CT. Costs were assessed on the basis of the prospective PLASTIC-study, which evaluated adding 18FFDG-PET/CT and SL to staging advanced gastric cancer (cT3-4 and/or cN+) in 18 Dutch hospitals. The Dutch Healthcare Authority provided 18FFDG-PET/CT unit costs. SL unit costs were calculated bottom-up. Gastrectomy-associated costs were collected with hospital claim data until 30 days postoperatively. Uncertainty was assessed in a probabilistic sensitivity analysis (1000 iterations). RESULTS 18FFDG-PET/CT costs were €1104 including biopsy/cytology. Bottom-up calculations totaled €1537 per SL. D2-gastrectomy costs were €19,308. Total costs per patient were €18,137 for strategy 1, €17,079 for strategy 2, and €19,805 for strategy 3. If all patients undergo gastrectomy, total costs were €18,959 per patient (strategy 4). Performing SL only reduced costs by €1880 per patient. Adding 18FFDG-PET/CT to SL increased costs by €1058 per patient; IQR €870-1253 in the sensitivity analysis. CONCLUSIONS For advanced gastric cancer, performing SL resulted in substantial cost savings by reducing unnecessary gastrectomies. In contrast, routine 18FFDG-PET/CT increased costs without substantially reducing unnecessary gastrectomies, and is not recommended due to limited impact with major costs. TRIAL REGISTRATION NCT03208621. This trial was registered prospectively on 30-06-2017.

Adjuvant Therapy for Patients with a Tumor-Positive Resection Margin After Neoadjuvant Chemoradiotherapy and Esophagectomy. Ann Surg Oncol 2024; 31:3813-3818. [PMID: 38245648 PMCID: PMC11076321 DOI: 10.1245/s10434-024-14912-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Accepted: 01/03/2024] [Indexed: 01/22/2024]
Abstract
BACKGROUND Approximately 4-9% of patients have a tumor-positive resection margin after neoadjuvant chemoradiotherapy (nCRT) and esophagectomy. Although it is associated with decreased survival, Western guidelines do not recommend adjuvant treatment. OBJECTIVE The aim of this study was to assess the proportion of patients who received adjuvant therapy, and to evaluate overall survival (OS) after esophagectomy in patients with a tumor-positive resection margin. METHODS Patients diagnosed with resectable (cT2-4a/cTxN0-3/NxM0) esophageal cancer between 2015 and 2022, and treated with nCRT followed by irradical esophagectomy, were selected from the Netherlands Cancer Registry. The primary outcome was the proportion of patients with a tumor-positive resection margin who started adjuvant treatment ≤16 weeks after esophagectomy, including chemotherapy/radiotherapy, immunotherapy, or targeted therapy. OS was calculated from the date of surgery until the date of death or last day of follow-up. RESULTS Overall, 376 patients were included in our study, of whom 357 were treated with nCRT. Of these 357 patients, 98.3% had a microscopically irradical resection and 1.7% had a macroscopically irradical resection. Approximately 72.3% of tumors showed a partial response (Mandard 2-3) and 11.8% showed little/no pathological response (Mandard 4-5) to nCRT. One of 357 patients underwent adjuvant chemoradiotherapy and 39 patients (61%) underwent adjuvant immunotherapy (nivolumab). The median and 5-year OS rate of all patients was 16.4 months (95% confidence interval 13.1-19.8) and 21%, respectively. CONCLUSION Real-world population-level data showed that no patients with a tumor-positive resection margin underwent adjuvant therapy following nCRT and esophagectomy prior to 2021. Interestingly, 61% of patients were treated with adjuvant nivolumab in 2021-2022. OS after irradical esophagectomy is poor and long-term data will explore the added value of nivolumab.

Intraperitoneal chemotherapy for peritoneal metastases of gastric origin: a systematic review and meta-analysis. Br J Surg 2024; 111:znae116. [PMID: 38722803 PMCID: PMC11081074 DOI: 10.1093/bjs/znae116] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Revised: 04/08/2024] [Accepted: 04/11/2024] [Indexed: 05/12/2024]
Abstract
BACKGROUND Gastric cancer with peritoneal metastases is associated with a dismal prognosis. Normothermic catheter-based intraperitoneal chemotherapy and normothermic pressurized intraperitoneal aerosol chemotherapy (PIPAC) are methods to deliver chemotherapy intraperitoneally leading to higher intraperitoneal concentrations of cytotoxic drugs compared to intravenous administration. We reviewed the effectiveness and safety of different methods of palliative intraperitoneal chemotherapy. METHODS Embase, MEDLINE, Web of Science and Cochrane were searched for articles studying the use of repeated administration of palliative intraperitoneal chemotherapy in patients with gastric cancer and peritoneal metastases, published up to January 2024. The primary outcome was overall survival. RESULTS Twenty-three studies were included, representing a total of 999 patients. The pooled median overall survival was 14.5 months. The pooled hazard ratio of the two RCTs using intraperitoneal paclitaxel and docetaxel favoured the intraperitoneal chemotherapy arm. The median overall survival of intraperitoneal paclitaxel, intraperitoneal docetaxel and PIPAC with cisplatin and doxorubicin were respectively 18.4 months, 13.2 months and 9.0 months. All treatment methods had a relatively safe toxicity profile. Conversion surgery after completion of intraperitoneal therapy was performed in 16% of the patients. CONCLUSIONS Repeated intraperitoneal chemotherapy, regardless of method of administration, is safe for patients with gastric cancer and peritoneal metastases. Conversion surgery after completion of the intraperitoneal chemotherapy is possible in a subset of patients.

Pathological response to neoadjuvant chemoradiotherapy for oesophageal squamous cell carcinoma in Eastern versus Western countries: meta-analysis. Br J Surg 2024; 111:znae083. [PMID: 38721902 DOI: 10.1093/bjs/znae083] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2023] [Revised: 02/23/2024] [Accepted: 03/05/2024] [Indexed: 05/15/2024]
Abstract
OBJECTIVE Locally advanced oesophageal squamous cell carcinoma can be treated with neoadjuvant chemoradiotherapy or chemotherapy followed by oesophagectomy. Discrepancies in pathological response rates have been reported between studies from Eastern versus Western countries. The aim of this study was to compare the pathological response to neoadjuvant chemoradiotherapy in Eastern versus Western countries. METHODS Databases were searched until November 2022 for studies reporting pCR rates after neoadjuvant chemoradiotherapy for oesophageal squamous cell carcinoma. Multi-level meta-analyses were performed to pool pCR rates separately for cohorts from studies performed in centres in the Sinosphere (East) or in Europe and the Anglosphere (West). RESULTS For neoadjuvant chemoradiotherapy, 51 Eastern cohorts (5636 patients) and 20 Western cohorts (3039 patients) were included. Studies from Eastern countries included more men, younger patients, more proximal tumours, and more cT4 and cN+ disease. Patients in the West were more often treated with high-dose radiotherapy, whereas patients in the East were more often treated with a platinum + fluoropyrimidine regimen. The pooled pCR rate after neoadjuvant chemoradiotherapy was 31.7% (95% c.i. 29.5% to 34.1%) in Eastern cohorts versus 40.4% (95% c.i. 35.0% to 45.9%) in Western cohorts (fixed-effect P = 0.003). For cohorts with similar cTNM stages, pooled pCR rates for the East and the West were 32.5% and 41.9% respectively (fixed-effect P = 0.003). CONCLUSION The pathological response to neoadjuvant chemoradiotherapy is less favourable in patients treated in Eastern countries compared with Western countries. Despite efforts to investigate accounting factors, the discrepancy in pCR rate cannot be entirely explained by differences in patient, tumour, or treatment characteristics.

Intraoperative Music to Promote Patient Outcome (IMPROMPTU): A Double-Blind Randomized Controlled Trial. J Surg Res 2024; 296:291-301. [PMID: 38306934 DOI: 10.1016/j.jss.2024.01.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Revised: 12/03/2023] [Accepted: 01/02/2024] [Indexed: 02/04/2024]
Abstract
INTRODUCTION Perioperative music can have beneficial effects on postoperative pain, anxiety, opioid requirement, and the physiological stress response to surgery. The aim was to assess the effects of intraoperative music during general anesthesia in patients undergoing surgery for esophagogastric cancer. MATERIALS AND METHODS The IMPROMPTU study was a double-blind, placebo-controlled, randomized multicenter trial. Adult patients undergoing surgery for stage II-III esophagogastric cancer were eligible. Exclusion criteria were a hearing impairment, insufficient Dutch language knowledge, corticosteroids use, or objection to hearing unknown music. Patients wore active noise-cancelling headphones intraoperatively with preselected instrumental classical music (intervention) or no music (control). Computerized randomization with centralized allocation, stratified according to surgical procedure using variable block sizes, was employed. Primary endpoint was postoperative pain on the first postoperative day. Secondary endpoints were postoperative pain during the first postoperative week, postoperative opioid requirement, intraoperative medication requirement, the stress response to surgery, postoperative complication rate, length of stay, and mortality, with follow-up lasting 30 d. RESULTS From November 2018 to September 2020, 145 patients were assessed and 83 randomized. Seventy patients (music n = 31, control n = 39) were analyzed. Median age was 70 [IQR 63-70], and 48 patients (69%) were male. Music did not reduce postoperative pain (numeric rating scale 1.8 (SD0.94) versus 2.0 (1.0), mean difference -0.28 [95% CI -0.76-0.19], P = 0.236). No statistically significant differences were seen in medication requirement, stress response, complication rate, or length of stay. CONCLUSIONS Intraoperative, preselected, classical music during esophagogastric cancer surgery did not significantly improve postoperative outcome and recovery when compared to no music using noise-cancelling headphones.

The yield of diagnostic laparoscopy with peritoneal lavage in gastric adenocarcinoma: A retrospective cohort study. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2024; 50:108233. [PMID: 38428107 DOI: 10.1016/j.ejso.2024.108233] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Revised: 01/24/2024] [Accepted: 02/25/2024] [Indexed: 03/03/2024]
Abstract
INTRODUCTION Diagnostic laparoscopy (DL) with peritoneal lavage has been adopted as a standard staging procedure for patients with gastric cancer (GC). Evaluation of the value of DL is important given ongoing improvements in diagnostic imaging and treatment. As contemporary data from European centres are sparse, this retrospective cohort study aimed to assess the yield of DL in patients with potentially curable gastric cancer, and to identify predictive factors for peritoneal metastases. METHODS Patients with adenocarcinoma of the stomach, treated between January 2016 and December 2018, were identified from institutional databases of two high volume European Upper-GI centres. Patients who underwent a DL with peritoneal lavage for potentially curable disease after clinical staging with imaging (cT1-4N0-3M0) were included. The primary outcome was the proportion of patients with a positive DL, defined as macroscopic metastatic disease, positive peritoneal cytology washings (PC+) or locally irresectable disease. RESULTS Some 80 of 327 included patients (24.5%) had a positive DL, excluding these patients from neoadjuvant treatment (66 of 327; 20.2%) and/or surgical resection (76 of 327; 23.2%). In 34 of 327 patients (10.3%), macroscopic metastatic disease was seen, with peritoneal deposits in 30 of these patients. Only 16 of 30 patients with peritoneal disease had positive cytology. Some 41 of 327 patients (12.5%) that underwent DL had PC+ in the absence of macroscopic metastases and five patients (1.5%) had an irresectable primary tumour. Diffuse type carcinoma had the highest risk of peritoneal dissemination, irrespective of cT and cN categories. CONCLUSION The diagnostic yield of staging laparoscopy is high, changing the management in approximately one quarter of patients. DL should be considered in patients with diffuse type carcinoma irrespective of cT and cN categories.

Perioperative Chemotherapy for Gastro-Esophageal or Gastric Cancer: Anthracyclin Triplets versus FLOT. Cancers (Basel) 2024; 16:1291. [PMID: 38610969 PMCID: PMC11011191 DOI: 10.3390/cancers16071291] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2024] [Revised: 03/18/2024] [Accepted: 03/25/2024] [Indexed: 04/14/2024] Open
Abstract
Background: The FLOT4-AIO trial (2019) showed improved survival with perioperative fluorouracil, leucovorin, oxaliplatin, and docetaxel (FLOT) compared to anthracyclin triplets in gastric cancer treatment. It is unclear whether these results extend to real-world scenarios in the Netherlands. This study aimed to compare outcomes of perioperative FLOT to anthracyclin triplets in a real-world Dutch gastric cancer population. Methods: Patients diagnosed with resectable (cT2-4a/cTxN0-3/NxM0) gastric or gastro-esophageal junction carcinoma between 2015-2021 who received neoadjuvant FLOT or anthracyclin triplets were selected from the Netherlands Cancer Registry. The primary outcome was overall survival (OS), analyzed through multivariable Cox regression. Secondary outcomes included pathological complete response (pCR), neoadjuvant chemotherapy cycle completion, surgical resection rates, and adjuvant therapy. Results: Adjusted OS showed no significant survival benefit (HR = 0.88, 95% CI 0.77-1.01, p = 0.07), even though the median OS was numerically improved by 8 months with FLOT compared to anthracyclin triplets (48.1 vs. 39.9 months, p = 0.16). FLOT patients were more likely to undergo diagnostic staging laparoscopies (74.2% vs. 44.1%, p < 0.001), had higher rates of completing neoadjuvant chemotherapy (OR = 1.35, 95% CI 1.09-1.68, p = 0.007), receiving adjuvant therapy (OR = 1.34, 95% CI 1.08-1.66, p = 0.08), and achieving pCR (OR = 1.52, 95% CI 1.05-2.20, p = 0.03). No significant differences were observed in (radical) resection rates. Conclusion(s): Real-world data showed no significant OS improvement for FLOT-treated patients compared to anthracyclin triplets, despite more staging laparoscopies. However, FLOT patients demonstrated higher rates of neoadjuvant therapy completion, proceeding to adjuvant therapy, and increased pCR rates. Therefore, we recommend the continued use of neoadjuvant FLOT therapy in the current clinical setting.

Fractures and other chest wall abnormalities after thoracotomy for esophageal cancer: A retrospective cohort study. World J Surg 2024; 48:662-672. [PMID: 38305774 DOI: 10.1002/wjs.12083] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2023] [Accepted: 01/06/2024] [Indexed: 02/03/2024]
Abstract
BACKGROUND Chest pain following a thoracotomy for esophageal cancer is frequently reported but poorly understood. This study aimed to (1) determine the prevalence of thoracotomy-related thoracic fractures on postoperative imaging and (2) compare complications, long-term pain, and quality of life in patients with versus without these fractures. METHODS This retrospective cohort study enrolled patients with esophageal cancer who underwent a thoracotomy between 2010 and 2020 with pre- and postoperative CTs (<1 and/or >6 months). Disease-free patients were invited for questionnaires on pain and quality of life. RESULTS Of a total of 366 patients, thoracotomy-related rib fractures were seen in 144 (39%) and thoracic transverse process fractures in 4 (2%) patients. Patients with thoracic fractures more often developed complications (89% vs. 74%, p = 0.002), especially pneumonia (51% vs. 39%, p = 0.032). Questionnaires were completed by 77 after a median of 41 (P25 -P75 28-91) months. Long-term pain was frequently (63%) reported but was not associated with thoracic fractures (p = 0.637), and neither were quality of life scores. CONCLUSIONS Thoracic fractures are prevalent in patients following a thoracotomy for esophageal cancer. These thoracic fractures were associated with an increased risk of postoperative complications, especially pneumonia, but an association with long-term pain or reduced quality of life was not confirmed.

Induction chemotherapy followed by response evaluation and esophagectomy for advanced esophageal cancer. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2024; 50:107968. [PMID: 38241878 DOI: 10.1016/j.ejso.2024.107968] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2023] [Revised: 12/27/2023] [Accepted: 01/10/2024] [Indexed: 01/21/2024]
Abstract
INTRODUCTION Patients with limited metastatic/advanced esophageal cancer not amenable for neoadjuvant therapy plus surgery have a poor prognosis and often receive palliative care. Alternatively, induction chemotherapy with response evaluation can be considered and in some patients surgery with curative intent may become feasible. The aim of this study was to evaluate the outcomes of patients treated with induction chemotherapy and to identify patient and/or tumor characteristics associated with survival. MATERIAL AND METHODS Patients with esophageal or junctional cancer who underwent induction chemotherapy between 2005 and 2021 were identified from an institutional database of a tertiary referral center. Response to therapy was assessed by (18F-FDG PET)/CT. Response to therapy and treatment options, including surgery or palliation, were discussed in the multidisciplinary tumor board. Overall survival (OS) was calculated using the Kaplan Meier method. Uni- and multivariable analyses were performed to identify prognostic factors for survival. RESULTS 238 patients were identified. The majority had esophageal adenocarcinoma (68.9 %) and were treated with a taxane/platinum-based chemotherapy (79.4 %). Response evaluation was performed in 233 patients and 154 of 238 patients (64.7 %) underwent surgical exploration. Resection was performed in 127 patients (53.4 %) resulting in a median and 5-year OS of 26.3 months (95 % CI 18.8-33.8) and 29.6 %, respectively. Presence of T4b (HR = 2.01, 95 % CI 1.02-3.92) and poorly differentiated tumor (HR = 1.45, 95 % CI 1.02-2.10) was associated with worse survival (p = 0.04). CONCLUSION In carefully selected patients with advanced disease not amenable for standard curative treatment, induction chemotherapy followed by esophagectomy may result in a 5-year overall survival of approximately 30 %.

18F-FDG-PET/CT to Detect Pathological Complete Response After Neoadjuvant Treatment in Patients with Cancer of the Esophagus or Gastroesophageal Junction: Accuracy and Long-Term Implications. J Gastrointest Cancer 2024; 55:270-280. [PMID: 37393217 PMCID: PMC11096198 DOI: 10.1007/s12029-023-00951-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 06/09/2023] [Indexed: 07/03/2023]
Abstract
PURPOSE The curative strategy for patients with esophageal cancer without distant metastases consists of esophagectomy with preceding chemo(radio)therapy (CRT). In 10-40% of patients treated with CRT, no viable tumor is detectable in the resection specimen (pathological complete response (pCR)). This study aims to define the clinical outcomes of patients with a pCR and to assess the accuracy of post-CRT FDG-PET/CT in the detection of a pCR. METHODS Four hundred sixty-three patients with cancer of the esophagus or gastroesophageal junction who underwent esophageal resection after CRT between 1994 and 2013 were included. Patients were categorized as pathological complete responders or noncomplete responders. Standardized uptake value (SUV) ratios of 135 post-CRT FDG-PET/CTs were calculated and compared with the pathological findings in the corresponding resection specimens. RESULTS Of the 463 included patients, 85 (18.4%) patients had a pCR. During follow-up, 25 (29.4%) of these 85 patients developed recurrent disease. Both 5-year disease-free survival (5y-DFS) and 5-year overall survival (5y-OS) were significantly higher in complete responders compared to noncomplete responders (5y-DFS 69.6% vs. 44.2%; P = 0.001 and 5y-OS 66.5% vs. 43.7%; P = 0.001). Not pCR, but only pN0 was identified as an independent predictor of (disease-free) survival. CONCLUSION Patients with a pCR have a higher probability of survival compared to noncomplete responders. One third of patients with a pCR do develop recurrent disease, and pCR can therefore not be equated with cure. FDG-PET/CT was inaccurate to predict pCR and therefore cannot be used as a sole diagnostic tool to predict pCR after CRT for esophageal cancer.

Abstract
BACKGROUND Decision counseling (DC) is offered to enable patients to reflect on their treatment preferences and to think through the consequences of alternative treatment options. However, the timing of DC is debatable. In this study, patients who underwent DC at different times were interviewed about their experiences, specifically focusing on the timing of DC. METHODS Patients with locally advanced esophageal cancer eligible for participation in a prospective cohort study on active surveillance (SANO-2 study) were offered DC either before or after neoadjuvant chemoradiotherapy (nCRT). Structured interviews were conducted by phone 1 week after DC, and responses were analyzed using frequency counts for the answers to set response categories. The primary outcome was the preferred time to receive DC, while the secondary outcome was the overall experience of patients with DC. RESULTS Overall, 40 patients were offered DC between 2021 and 2023. Patients who had counseling before the start of nCRT (n = 20) were satisfied with the timing of DC. Of the 20 patients who had DC after nCRT, 6 would have preferred counseling at an earlier time point. Patients who had DC both before or after the completion of nCRT reflected positively on DC. CONCLUSION It is recommended to introduce the option of DC as early as possible and discuss with the patient at which moment during the decision-making process they prefer to discuss all treatment options more extensively.

Abstract
OBJECTIVE To examine the influence of the LOGICA RCT (randomized controlled trial) upon the practice and outcomes of laparoscopic gastrectomy within the Netherlands. BACKGROUND Following RCTs the dissemination of complex interventions has been poorly studied. The LOGICA RCT included 10 Dutch centers and compared laparoscopic to open gastrectomy. METHODS Data were obtained from the Dutch Upper Gastrointestinal Cancer Audit (DUCA) on all gastrectomies performed in the Netherlands (2012-2021), and the LOGICA RCT from 2015 to 2018. Multilevel multivariable logistic regression analyses were performed to assess the effect of laparoscopic versus open gastrectomy upon clinical outcomes before, during, and after the LOGICA RCT. RESULTS Two hundred eleven patients from the LOGICA RCT (105 open vs 106 laparoscopic) and 4131 patients from the DUCA data set (1884 open vs 2247 laparoscopic) were included. In 2012, laparoscopic gastrectomy was performed in 6% of patients, increasing to 82% in 2021. No significant effect of laparoscopic gastrectomy on postoperative clinical outcomes was observed within the LOGICA RCT. Nationally within DUCA, a shift toward a beneficial effect of laparoscopic gastrectomy upon complications was observed, reaching a significant reduction in overall [adjusted odds ratio (aOR):0.62; 95% CI: 0.46-0.82], severe (aOR: 0.64; 95% CI: 0.46-0.90) and cardiac complications (aOR: 0.51; 95% CI: 0.30-0.89) after the LOGICA trial. CONCLUSIONS The wider benefits of the LOGICA trial included the safe dissemination of laparoscopic gastrectomy across the Netherlands. The robust surgical quality assurance program in the design of the LOGICA RCT was crucial to facilitate the national dissemination of the technique following the trial and reducing potential patient harm during surgeons learning curve.

[PMID: 38398190 PMCID: PMC10887104 DOI: 10.3390/cancers16040797] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2024] [Revised: 02/02/2024] [Accepted: 02/13/2024] [Indexed: 02/25/2024] Open
Abstract
Approximately 10-12% of patients with oesophageal or gastric cancer (OGC) present with oligometastatic disease at diagnosis. It remains unclear if there is a role for radical surgery in these patients. We aimed to assess the outcomes of OGC patients who underwent simultaneous treatment for the primary tumour and synchronous liver metastases. Patients with OGC who underwent surgical treatment between 2008 and 2020 for the primary tumour and up to five synchronous liver metastases aiming for complete tumour removal or ablation (i.e., no residual tumour) were identified from four institutional databases. The primary outcome was overall survival (OS), calculated with the Kaplan-Meier method. Secondary outcomes were disease-free survival and postoperative outcomes. Thirty-one patients were included, with complete follow-up data for 30 patients. Twenty-six patients (84%) received neoadjuvant therapy followed by response evaluation. Median OS was 21 months [IQR 9-36] with 2- and 5-year survival rates of 43% and 30%, respectively. While disease recurred in 80% of patients (20 of 25 patients) after radical resection, patients with a solitary liver metastasis had a median OS of 34 months. The number of liver metastases was a prognostic factor for OS (solitary metastasis aHR 0.330; p-value = 0.025). Thirty-day mortality was zero and complications occurred in 55% of patients. Long-term survival can be achieved in well-selected patients who undergo surgical resection of the primary tumour and local treatment of synchronous liver metastases. In particular, patients with a solitary liver metastasis seem to have a favourable prognosis.

Abstract
PURPOSE The purpose of this study was to investigate whether 18F-fluorodeoxyglucose ( 18 F-FDG) PET/MRI may potentially improve tumor detection after neoadjuvant chemoradiotherapy (nCRT) for esophageal cancer. METHODS This was a prospective, single-center feasibility study. At 6-12 weeks after nCRT, patients underwent standard 18 F-FDG PET/computed tomography (CT) followed by PET/MRI, and completed a questionnaire to evaluate burden. Two teams of readers either assessed the 18 F-FDG PET/CT or the 18 F-FDG PET/MRI first; the other scan was assessed 1 month later. Maximum standardized uptake value corrected for lean body mass (SUL max ) and mean apparent diffusion coefficient (ADC mean ) were measured at the primary tumor location. Histopathology of the surgical resection specimen served as the reference standard for diagnostic accuracy calculations. When patients had a clinically complete response and continued active surveillance, response evaluations until 9 months after nCRT served as a proxy for ypT and ypN (i.e. 'ycT' and 'ycN'). RESULTS In the 21 included patients [median age 70 (IQR 62-75), 16 males], disease recurrence was found in the primary tumor in 14 (67%) patients (of whom one ypM+, detected on both scans) and in locoregional lymph nodes in six patients (29%). Accuracy (team 1/team 2) to detect yp/ycT+ with 18 F-FDG PET/MRI vs. 18 F-FDG PET/CT was 38/57% vs. 76/61%. For ypN+, accuracy was 63/53% vs. 63/42%, resp. Neither SUL max (both scans) nor ADC mean were discriminatory for yp/ycT+ . Fourteen of 21 (67%) patients were willing to undergo a similar 18 F-FDG PET/MRI examination in the future. CONCLUSION 18 F-FDG PET/MRI currently performs comparably to 18 F-FDG PET/CT. Improvements in the scanning protocol, increasing reader experience and performing serial scans might contribute to enhancing the accuracy of tumor detection after nCRT using 18 F-FDG PET/MRI.

Prognostic value of Mandard score and nodal status for recurrence patterns and survival after multimodal treatment of oesophageal adenocarcinoma. Br J Surg 2024; 111:znae034. [PMID: 38387083 PMCID: PMC10883709 DOI: 10.1093/bjs/znae034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Revised: 01/30/2024] [Accepted: 01/31/2024] [Indexed: 02/24/2024]
Abstract
BACKGROUND This study evaluated the association of pathological tumour response (tumour regression grade, TRG) and a novel scoring system, combining both TRG and nodal status (TRG-ypN score; TRG1-ypN0, TRG>1-ypN0, TRG1-ypN+ and TRG>1-ypN+), with recurrence patterns and survival after multimodal treatment of oesophageal adenocarcinoma. METHODS This Dutch nationwide cohort study included patients treated with neoadjuvant chemoradiotherapy followed by oesophagectomy for distal oesophageal or gastro-oesophageal junctional adenocarcinoma between 2007 and 2016. The primary endpoint was the association of Mandard score and TRG-ypN score with recurrence patterns (rate, location, and time to recurrence). The secondary endpoint was overall survival. RESULTS Among 2746 inclusions, recurrence rates increased with higher Mandard scores (TRG1 30.6%, TRG2 44.9%, TRG3 52.9%, TRG4 61.4%, TRG5 58.2%; P < 0.001). Among patients with recurrent disease, the distribution (locoregional versus distant) was the same for the different TRG groups. Patients with TRG1 developed more brain recurrences (17.7 versus 9.8%; P = 0.001) and had a longer mean overall survival (44 versus 35 months; P < 0.001) than those with TRG>1. The TRG>1-ypN+ group had the highest recurrence rate (64.9%) and worst overall survival (mean 27 months). Compared with the TRG>1-ypN0 group, patients with TRG1-ypN+ had a higher risk of recurrence (51.9 versus 39.6%; P < 0.001) and worse mean overall survival (33 versus 41 months; P < 0.001). CONCLUSION Improved tumour response to neoadjuvant therapy was associated with lower recurrence rates and higher overall survival rates. Among patients with recurrent disease, TRG1 was associated with a higher incidence of brain recurrence than TRG>1. Residual nodal disease influenced prognosis more negatively than residual disease at the primary tumour site.

Abstract
BACKGROUND Esophagectomy is associated with lasting effect on health-related quality of life (HRQOL). Patients desire detailed information on the expected impact of treatment on their postoperative HRQOL. The aim of the present study is to identify clinicopathological characteristics predictive for changes in short-term and long-term HRQOL after neoadjuvant chemoradiotherapy (nCRT) and surgery. METHODS HRQOL was measured using EORTC-QLQ-C30 and QLQ-OES24 questionnaires prior to nCRT, three, six, nine and twelve months postoperatively and at a minimum of six years postoperatively. Based on previous experience and available literature, several subgroups were predefined for different clinicopathological characteristics: baseline global HRQOL, WHO performance status, histology, tumor stage and tumor location. The primary endpoints of the present study were the change compared to baseline in the HRQOL dimensions physical functioning and eating problems. Secondary endpoints were global HRQOL, fatigue and emotional problems. RESULTS In total, 134 (76%) of 177 patients who received HRQOL questionnaires, responded at baseline. Patients who reported a high baseline global HRQOL had a more severe deterioration in eating problems (+14.5 to + 18.0), global HRQOL (-16.0 to -28.0) and fatigue (+10.5 to +14.9) up to six years postoperatively compared to patients who reported a low baseline global HRQOL. Patients who had stage 2 tumor (UICC 6th edition) had a more severe deterioration in eating problems (+14.6 to +19.0) and global HRQOL (-10.1 to -17.1) than patients who had stage 3 tumor. CONCLUSIONS The results suggest that patients with locally advanced esophageal cancer in favorable condition at baseline decline more in terms of various HRQOL outcomes.

The Comprehensive Complication Index versus Clavien-Dindo grading after laparoscopic and open D2-gastrectomy in the multicenter randomized LOGICA-trial. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2023; 49:107095. [PMID: 37913608 DOI: 10.1016/j.ejso.2023.107095] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Accepted: 09/22/2023] [Indexed: 11/03/2023]
Abstract
BACKGROUND Complications can be classified using the most-severe Clavien-Dindo-Classification (CDC) per patient or the total complication burden per patient expressed in the Comprehensive Complication Index (CCI). This study determined the additional value of CCI to CDC in examining the impact of complications after gastric cancer surgery. METHODS The CCI and CDC were determined in the multicenter randomized LOGICA-trial comparing laparoscopic versus open D2-gastrectomy for cancer (cT1-4aN0-3M0). Differences in median CCI between laparoscopic and open gastrectomy were compared for overall postoperative complications and cardiovascular, gastrointestinal, infectious, pulmonary, and other complications. CCI and CDC were correlated to hospitalization, ICU-stay and reoperations using Spearman's rho-test and compared with standard Fisher's z-transformation. RESULTS Between 2015 and 2018, 211 patients underwent laparoscopic (n = 106) or open (n = 105) D2-gastrectomy, and 157 (74%) received neoadjuvant chemotherapy. Median CCI was comparable between laparoscopic versus open gastrectomy regarding overall complications (CCI 0 [IQR 0-23.5] versus 0 [IQR 0-22.6]; p = 0.755) and subgroups of complications (p > 0.05). Both CCI and CDC showed moderate positive correlations for hospitalization (rs = 0.646 versus rs = 0.628; p = 0.001, difference clinically irrelevant), and reoperations (rs = 0.590 versus rs = 0.599; p = 0.070), and weak correlations for ICU-stay (rs = 0.446 versus rs = 0.440; p = 0.189). CONCLUSIONS The CCI is a composite scoring system based on the CDC and reflects a subjective interpretation of complication burden from the perspectives of both physicians and patients, following abdominal surgery other than gastrectomy. Implementing CCI showed no clinically relevant benefit and caused additional workload compared to CDC for assessing complication burden. Therefore, using the CCI alongside the CDC after gastric cancer surgery is not recommended.

Abstract
BACKGROUND This study assesses the incidence of gastrointestinal symptoms in the first year after resection of esophageal or gastric cancer and its association with health-related quality of life (HRQoL), functioning, work productivity, and daily activities. PATIENTS AND METHODS Patients diagnosed with esophageal or gastric cancer between 2015 and 2021, who underwent a resection, and completed ≥ 2 questionnaires from the time intervals prior to resection and 0-3, 3-6, 6-9, and 9-12 months after resection were included. Multivariable generalized linear mixed models were used to assess changes in gastrointestinal symptoms over time and the impact of the number of gastrointestinal symptoms on HRQoL, functioning, work productivity, and daily activities for patients who underwent an esophagectomy or gastrectomy separately. RESULTS The study population consisted of 961 (78.8%) and 259 (21.2%) patients who underwent an esophagectomy and gastrectomy, respectively. For both groups, the majority of gastrointestinal symptoms changed significantly over time. Most clinically relevant differences were observed 0-3 after resection compared with prior to resection and included increased diarrhea, appetite loss, and eating restrictions, and specifically after esophagectomy dry mouth, trouble with coughing, and trouble talking. At 9-12 after resection one or more severe gastrointestinal symptoms were reported by 38.9% after esophagectomy and 33.7% after gastrectomy. A higher number of gastrointestinal symptoms was associated with poorer functioning, lower HRQoL, higher impairment in daily activities, and lower work productivity. CONCLUSIONS This study shows that gastrointestinal symptoms are frequently observed and burdensome after esophagectomy or gastrectomy, highlighting the importance to address these sequelae for high quality survivorship.

Long-Term Survival Associated with Direct Oral Feeding Following Minimally Invasive Esophagectomy: Results from a Randomized Controlled Trial (NUTRIENT II). Cancers (Basel) 2023; 15:4856.

Abstract
Advancements in perioperative care have improved postoperative morbidity and recovery after esophagectomy. The direct start of oral intake can also enhance short-term outcomes following minimally invasive Ivor Lewis esophagectomy (MIE-IL). Subsequently, short-term outcomes may affect long-term survival. This planned sub-study of the NUTRIENT II trial, a multicenter randomized controlled trial, investigated the long-term survival of direct versus delayed oral feeding following MIE-IL. The outcomes included 3- and 5-year overall survival (OS) and disease-free survival (DFS), and the influence of complications and caloric intake on OS. After excluding cases of 90-day mortality, 145 participants were analyzed. Of these, 63 patients (43.4%) received direct oral feeding. At 3 years, OS was significantly better in the direct oral feeding group (p = 0.027), but not at 5 years (p = 0.115). Moreover, 5-year DFS was significantly better in the direct oral feeding group (p = 0.047) and a trend towards improved DFS was shown at 3 years (p = 0.079). Postoperative complications and caloric intake on day 5 did not impact OS. The results of this study show a tendency of improved 3-year OS and 5-year DFS, suggesting a potential long-term survival benefit in patients receiving direct oral feeding after esophagectomy. However, the findings should be further explored in larger future trials.

Surgeon's steering behaviour towards patients to participate in a cluster randomised trial on active surveillance for oesophageal cancer: A qualitative study. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2023; 49:106935.

Abstract
INTRODUCTION Few studies have been conducted into how physicians use steering behaviour that may persuade patients to choose for a particular treatment, let alone to participate in a randomised trial. The aim of this study is to assess if and how surgeons use steering behaviour in their information provision to patients in their choice to participate in a stepped-wedge cluster randomised trial investigating an organ sparing treatment in (curable) oesophageal cancer (SANO trial). MATERIALS AND METHODS A qualitative study was performed. Thematic content analysis was applied to audiotaped and transcribed consultations of twenty patients with eight different oncological surgeons in three Dutch hospitals. Patients could choose to participate in a clinical trial in which an experimental treatment of 'active surveillance' (AS) was offered. Patients who did not want to participate underwent standard treatment: neoadjuvant chemoradiotherapy followed by oesophagectomy. RESULTS Surgeons used various techniques to steer patients towards one of the two options, mostly towards AS. The presentation of pros and cons of treatment options was imbalanced: positive framing of AS was used to steer patients towards the choice for AS, and negative framing of AS to make the choice for surgery more attractive. Further, steering language, i.e. suggestive language, was used, and surgeons seemed to use the timing of the introduction of the different treatment options, to put more focus on one of the treatment options. CONCLUSION Awareness of steering behaviour can help to guide physicians in more objectively informing patients on participation in future clinical trials.

Abstract
BACKGROUND 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
BACKGROUND This study explores patients' need for information and support in deciding on esophageal cancer treatment, when experimental active surveillance and standard surgery are both feasible. METHODS This psychological companion study was conducted alongside the Dutch SANO-trial (Surgery As Needed for Oesophageal cancer). In-depth interviews and questionnaires were used to collect data from patients who declined participation in the trial because they had a strong preference for either active surveillance (n = 20) or standard surgery (n = 20). Data were analyzed using both qualitative and quantitative techniques. RESULTS Patients prefer to receive information directly from their doctors and predominantly rely on this information to make a treatment decision. Other information resources are largely used to confirm their treatment decision. Patients highly value support from their loved ones and appreciate emphatic doctors to actively involve them in the decision-making process. Overall, patients' needs for information and support during decision-making were met. CONCLUSIONS The importance of shared decision-making and the role doctors have in this process is underlined. The role of doctors is essential at the initial phase of decision-making: Once patients seem to have formed their treatment preference for either active surveillance or surgery, the influence of external resources (including doctors) may be limited.

External validation of 18F-FDG PET-based radiomic models on identification of residual oesophageal cancer after neoadjuvant chemoradiotherapy. Nucl Med Commun 2023:00006231-990000000-00152.

Abstract
OBJECTIVES Detection of residual oesophageal cancer after neoadjuvant chemoradiotherapy (nCRT) is important to guide treatment decisions regarding standard oesophagectomy or active surveillance. The aim was to validate previously developed 18F-FDG PET-based radiomic models to detect residual local tumour and to repeat model development (i.e. 'model extension') in case of poor generalisability. METHODS This was a retrospective cohort study in patients collected from a prospective multicentre study in four Dutch institutes. Patients underwent nCRT followed by oesophagectomy between 2013 and 2019. Outcome was tumour regression grade (TRG) 1 (0% tumour) versus TRG 2-3-4 (≥1% tumour). Scans were acquired according to standardised protocols. Discrimination and calibration were assessed for the published models with optimism-corrected AUCs >0.77. For model extension, the development and external validation cohorts were combined. RESULTS Baseline characteristics of the 189 patients included [median age 66 years (interquartile range 60-71), 158/189 male (84%), 40/189 TRG 1 (21%) and 149/189 (79%) TRG 2-3-4] were comparable to the development cohort. The model including cT stage plus the feature 'sum entropy' had best discriminative performance in external validation (AUC 0.64, 95% confidence interval 0.55-0.73), with a calibration slope and intercept of 0.16 and 0.48 respectively. An extended bootstrapped LASSO model yielded an AUC of 0.65 for TRG 2-3-4 detection. CONCLUSION The high predictive performance of the published radiomic models could not be replicated. The extended model had moderate discriminative ability. The investigated radiomic models appeared inaccurate to detect local residual oesophageal tumour and cannot be used as an adjunct tool for clinical decision-making in patients.

Abstract
BACKGROUND Neoadjuvant chemoradiotherapy (nCRT) followed by esophagectomy is a standard treatment for potentially curable esophageal cancer. Active surveillance in patients with a clinically complete response (cCR) 12 weeks after nCRT is regarded as possible alternative to standard surgery. The aim of this study is to monitor the safety, adherence and effectiveness of active surveillance in patients outside a randomized trial. METHODS This nationwide prospective cohort study aims to accrue operable patients with non-metastatic histologically proven adenocarcinoma or squamous cell carcinoma of the esophagus or esophagogastric junction. Patients receive nCRT and response evaluation consists of upper endoscopy with bite-on-bite biopsies, endoscopic ultrasonography plus fine-needle aspiration of suspicious lymph nodes and 18F-fluorodeoxyglucose positron emission tomography/computed tomography scan. When residue or regrowth of tumor in the absence of distant metastases is detected, surgical resection is advised. Patients with cCR after nCRT are suitable to undergo active surveillance. Patients can consult an independent physician or psychologist to support decision-making. Primary endpoint is the number and severity of adverse events in patients with cCR undergoing active surveillance, defined as complications from response evaluations, delayed surgery and the development of distant metastases. Secondary endpoints include timing and quality of diagnostic modalities, overall survival, progression-free survival, fear of cancer recurrence and decisional regret. DISCUSSION Active surveillance after nCRT may be an alternative to standard surgery in patients with esophageal cancer. Similar to organ-sparing approaches applied in other cancer types, the safety and efficacy of active surveillance needs monitoring before data from randomized trials are available. TRIAL REGISTRATION The SANO-2 study has been registered at ClinicalTrials.gov as NCT04886635 (May 14, 2021) - Retrospectively registered.

Abstract
OBJECTIVE This study evaluated the nationwide trends in care and accompanied postoperative outcomes for patients with distal esophageal and gastro-esophageal junction cancer. SUMMARY OF BACKGROUND DATA The introduction of transthoracic esophagectomy, minimally invasive surgery, and neo-adjuvant chemo(radio)therapy changed care for patients with esophageal cancer. METHODS Patients after elective transthoracic and transhiatal esophagectomy for distal esophageal or gastroesophageal junction carcinoma in the Netherlands between 2007-2016 were included. The primary aim was to evaluate trends in both care and postoperative outcomes for the included patients. Additionally, postoperative outcomes after transthoracic and tran-shiatal esophagectomy were compared, stratified by time periods. RESULTS Among 4712 patients included, 74% had distal esophageal tumors and 87% had adenocarcinomas. Between 2007 and 2016, the proportion of transthoracic esophagectomy increased from 41% to 81%, and neo-adjuvant treatment and minimally invasive esophagectomy increased from 31% to 96%, and from 7% to 80%, respectively. Over this 10-year period, postoperative outcomes improved: postoperative morbidity decreased from 66.6% to 61.8% ( P = 0.001), R0 resection rate increased from 90.0% to 96.5% (P <0.001), median lymph node harvest increased from 15 to 19 ( P <0.001), and median survival increased from 35 to 41 months ( P = 0.027). CONCLUSION In this nationwide cohort, a transition towards more neo-adju-vant treatment, transthoracic esophagectomy and minimally invasive surgery was observed over a 10-year period, accompanied by decreased postoperative morbidity, improved surgical radicality and lymph node harvest, and improved survival.

Patient preferences for active surveillance vs standard surgery after neoadjuvant chemoradiotherapy in oesophageal cancer treatment: The NOSANO-study. Int J Cancer 2023; 152:1183-1190. [PMID: 36250325 PMCID: PMC10092042 DOI: 10.1002/ijc.34327] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2022] [Revised: 09/13/2022] [Accepted: 10/04/2022] [Indexed: 01/21/2023]
Abstract
Active surveillance may be a safe and effective treatment in oesophageal cancer patients with a clinically complete response after neoadjuvant chemoradiotherapy (nCRT). In the NOSANO-study we gained insight in patients' motive to opt for either an experimental treatment called active surveillance or for standard immediate surgery. Both qualitative and quantitative analyses methods were used. Forty patients were interviewed about their treatment preference, 3 months after completion of nCRT (T1). Data were recorded, transcribed verbatim and analysed according to the principles of grounded theory. In addition, at T1 and T2 (12 months after completion of nCRT) questionnaires on health-related quality of life, coping, anxiety and decisional regret (only T2) were administered. Interview data analyses resulted in a conceptual model with 'dealing with threat of cancer' as the central theme. Patients preferring active surveillance tend to cope with this threat by confiding in their bodies and good outcomes. Their mind-set is one of 'enjoy life now'. Patients preferring surgery tend to cope by minimizing uncertainty and eliminating the source of cancer. Their mind-set is one of 'don't give up, act now'. Furthermore, questionnaire results showed that patients with a preference for standard surgery had a lower quality of life. Patient preferences are individualized and thus difficult to predict. Our model can help healthcare professionals to determine patient preferences for treatment. Coping style and mind-set seem to be determining factors here.

A quantitative assessment of perfusion of the gastric conduit after oesophagectomy using near-infrared fluorescence with indocyanine green. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2023; 49:990-995. [PMID: 36914531 DOI: 10.1016/j.ejso.2023.02.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2022] [Revised: 01/20/2023] [Accepted: 02/26/2023] [Indexed: 03/06/2023]
Abstract
INTRODUCTION Anastomotic leakage is a severe complication after oesophageal resection with gastric conduit reconstruction. Poor perfusion of the gastric conduit plays an important role in the development of anastomotic leakage. Quantitative near-infrared (NIR) fluorescence angiography with indocyanine green (ICG-FA) is an objective technique that can be used for perfusion assessment. This study aims to assess perfusion patterns of the gastric conduit with quantitative ICG-FA. METHODS In this exploratory study, 20 patients undergoing oesophagectomy with gastric conduit reconstruction were included. A standardized NIR ICG-FA video of the gastric conduit was recorded. Postoperatively, the videos were quantified. Primary outcomes were the time-intensity curves and nine perfusion parameters from contiguous regions of interest on the gastric conduit. A secondary outcome was the inter-observer agreement of subjective interpretation of the ICG-FA videos between six surgeons. The inter-observer agreement was tested with an intraclass correlation coefficient (ICC). RESULTS In a total of 427 curves, three distinct perfusion patterns were recognized: pattern 1 (steep inflow, steep outflow); pattern 2 (steep inflow, minor outflow); and pattern 3 (slow inflow, no outflow). All perfusion parameters were significantly different between the perfusion patterns. The inter-observer agreement was poor - moderate (ICC:0.345,95%CI:0.164-0.584). DISCUSSION This was the first study to describe perfusion patterns of the complete gastric conduit after oesophagectomy. Three distinct perfusion patterns were observed. The poor inter-observer agreement of the subjective assessment underlines the need for quantification of ICG-FA of the gastric conduit. Further studies should evaluate the predictive value of perfusion patterns and parameters on anastomotic leakage.

Cost-effectiveness of Laparoscopic vs Open Gastrectomy for Gastric Cancer: An Economic Evaluation Alongside a Randomized Clinical Trial. JAMA Surg 2023; 158:120-128. [PMID: 36576822 PMCID: PMC9856973 DOI: 10.1001/jamasurg.2022.6337] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2022] [Accepted: 08/11/2022] [Indexed: 12/29/2022]
Abstract
Importance Laparoscopic gastrectomy is rapidly being adopted worldwide as an alternative to open gastrectomy to treat gastric cancer. However, laparoscopic gastrectomy might be more expensive as a result of longer operating times and more expensive surgical materials. To date, the cost-effectiveness of both procedures has not been prospectively evaluated in a randomized clinical trial. Objective To evaluate the cost-effectiveness of laparoscopic compared with open gastrectomy. Design, Setting, and Participants In this multicenter randomized clinical trial of patients undergoing total or distal gastrectomy in 10 Dutch tertiary referral centers, cost-effectiveness data were collected alongside a multicenter randomized clinical trial on laparoscopic vs open gastrectomy for resectable gastric adenocarcinoma (cT1-4aN0-3bM0). A modified societal perspective and 1-year time horizon were used. Costs were calculated on the individual patient level by using hospital registry data and medical consumption and productivity loss questionnaires. The unit costs of laparoscopic and open gastrectomy were calculated bottom-up. Quality-adjusted life-years (QALYs) were calculated with the EuroQol 5-dimension questionnaire, in which a value of 0 indicates death and 1 indicates perfect health. Missing questionnaire data were imputed with multiple imputation. Bootstrapping was performed to estimate the uncertainty surrounding the cost-effectiveness. The study was conducted from March 17, 2015, to August 20, 2018. Data analyses were performed between September 1, 2020, and November 17, 2021. Interventions Laparoscopic vs open gastrectomy. Main Outcomes and Measures Evaluations in this cost-effectiveness analysis included total costs and QALYs. Results Between 2015 and 2018, 227 patients were included. Mean (SD) age was 67.5 (11.7) years, and 140 were male (61.7%). Unit costs for initial surgery were calculated to be €8124 (US $8087) for laparoscopic total gastrectomy, €7353 (US $7320) for laparoscopic distal gastrectomy, €6584 (US $6554) for open total gastrectomy, and €5893 (US $5866) for open distal gastrectomy. Mean total costs after 1-year follow-up were €26 084 (US $25 965) in the laparoscopic group and €25 332 (US $25 216) in the open group (difference, €752 [US $749; 3.0%]). Mean (SD) QALY contributions during 1 year were 0.665 (0.298) in the laparoscopic group and 0.686 (0.288) in the open group (difference, -0.021). Bootstrapping showed that these differences between treatment groups were relatively small compared with the uncertainty of the analysis. Conclusions and Relevance Although the laparoscopic gastrectomy itself was more expensive, after 1-year follow-up, results suggest that differences in both total costs and effectiveness were limited between laparoscopic and open gastrectomy. These results support centers' choosing, based on their own preference, whether to (de)implement laparoscopic gastrectomy as an alternative to open gastrectomy.

Abstract
Malignancies of the peritoneal cavity are associated with a dismal prognosis. Systemic chemotherapy is the gold standard for patients with unresectable peritoneal disease, but its intraperitoneal effect is hampered by the peritoneal-plasma barrier. Intraperitoneal chemotherapy, which is administered repeatedly into the peritoneal cavity through a peritoneal implanted port, could provide a novel treatment modality for this patient population. This review provides a systematic overview of intraperitoneal used drugs, the performed clinical studies so far, and the complications of the peritoneal implemental ports. Several anticancer drugs have been studied for intraperitoneal application, with the taxanes paclitaxel and docetaxel as the most commonly used drug. Repeated intraperitoneal chemotherapy, mostly in combination with systemic chemotherapy, has shown promising results in Phase I and Phase II studies for several tumor types, such as gastric cancer, ovarian cancer, colorectal cancer, and pancreatic cancer. Two Phase III studies for intraperitoneal chemotherapy in gastric cancer have been performed so far, but the results regarding the superiority over standard systemic chemotherapy alone, are contradictory. Pressurized intraperitoneal administration, known as PIPAC, is an alternative way of administering intraperitoneal chemotherapy, and the first prospective studies have shown a tolerable safety profile. Although intraperitoneal chemotherapy might be a standard treatment option for patients with unresectable peritoneal disease, more Phase II and Phase III studies focusing on tolerability profiles, survival rates, and quality of life are warranted in order to establish optimal treatment schedules and to establish a potential role for intraperitoneal chemotherapy in the approach to unresectable peritoneal disease.

Abstract
INTRODUCTION This population-based cohort study analysed treatment, overall survival (OS), and independent prognostic factors for OS in gastric cancer patients with liver metastases. METHODS Between 2015 and 2017, patients with synchronous metastatic gastric or gastroesophageal junction adenocarcinoma limited to the liver were included from the prospectively maintained population-based Netherlands Cancer Registry. Liver oligometastatic disease (OMD) was defined as ≤3 liver metastases. The primary outcome was OS. Independent prognostic factors for OS were analysed using multivariable Cox regression analysis. RESULTS A total 295 patients with metastases limited to the liver were included. The primary tumour was resected in four patients (1.4%). Treatment for liver metastases consisted of chemotherapy alone (28.1%), trastuzumab plus chemotherapy (4.7%), surgery (1.0%), or best supportive care (67.5%). Median OS across all included patients was 4.0 months (95% confidence interval [CI]: 3.1-4.5). Liver OMD was detected in 77 patients (26%). Treatment for liver OMD consisted of chemotherapy alone (24.6%), trastuzumab plus chemotherapy (5.2%), surgery (3.9%), or best supportive care (67.5%). Median OS among patients with liver OMD was 5.7 months (95% CI: 4.8-7.5). Across all patients, better OS was independently associated with liver OMD (hazard ratio [HR] 0.66, 95% CI: 0.50-0.87), trastuzumab (HR 0.41, 95% CI: 0.23-0.72) but not with triplet compared with doublet chemotherapy (HR 0.94, 95% CI: 0.57-2.87). Worse OS was independently associated with unknown nodal stage versus cN0 (HR 1.74, 95% CI: 1.17-2.60), diffuse-type versus intestinal-type adenocarcinoma (HR 2.06, 95% CI: 1.32-3.20), and monotherapy or best supportive care versus doublet chemotherapy (HR 1.72, 95% CI: 1.03-2.87, and HR 3.61, 95% CI: 2.55-5.10, respectively). CONCLUSION In this population-based cohort study, liver OMD was detected in 26% of patients. Liver OMD and trastuzumab treatment were independently associated with better OS while triplet as compared with doublet chemotherapy was not. OS among patients with liver OMD nevertheless remained poor. The concept of OMD and the benefit of resection of liver OMD may still have been relatively unknown in this disease type during the study inclusion years.

Detection of circulating tumour DNA after neoadjuvant chemoradiotherapy in patients with locally advanced oesophageal cancer. J Pathol 2023; 259:35-45. [PMID: 36196486 PMCID: PMC10092085 DOI: 10.1002/path.6016] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2022] [Revised: 09/05/2022] [Accepted: 09/30/2022] [Indexed: 11/05/2022]
Abstract
Active surveillance instead of standard surgery after neoadjuvant chemoradiotherapy (nCRT) has been proposed for patients with oesophageal cancer. Circulating tumour DNA (ctDNA) may be used to facilitate selection of patients for surgery. We show that detection of ctDNA after nCRT seems highly suggestive of major residual disease. Tumour biopsies and blood samples were taken before, and 6 and 12 weeks after, nCRT. Biopsies were analysed with regular targeted next-generation sequencing (NGS). Circulating cell-free DNA (cfDNA) was analysed using targeted NGS with unique molecular identifiers and digital polymerase chain reaction. cfDNA mutations matching pre-treatment biopsy mutations confirmed the presence of ctDNA. In total, 31 patients were included, of whom 24 had a biopsy mutation that was potentially detectable in cfDNA (77%). Pre-treatment ctDNA was detected in nine of 24 patients (38%), four of whom had incurable disease progression before surgery. Pre-treatment ctDNA detection had a sensitivity of 47% (95% CI 24-71) (8/17), specificity of 85% (95% CI 42-99) (6/7), positive predictive value (PPV) of 89% (95% CI 51-99) (8/9), and negative predictive value (NPV) of 40% (95% CI 17-67) (6/15) for detecting major residual disease (>10% residue in the resection specimen or progression before surgery). After nCRT, ctDNA was detected in three patients, two of whom had disease progression. Post-nCRT ctDNA detection had a sensitivity of 21% (95% CI 6-51) (3/14), specificity of 100% (95% CI 56-100) (7/7), PPV of 100% (95% CI 31-100) (3/3), and NPV of 39% (95% CI 18-64) (7/18) for detecting major residual disease. The addition of ctDNA to the current set of diagnostics did not lead to more patients being clinically identified with residual disease. These results indicate that pre-treatment and post-nCRT ctDNA detection may be useful in identifying patients at high risk of disease progression. The addition of ctDNA analysis to the current set of diagnostic modalities may not improve detection of residual disease after nCRT. © 2022 The Authors.

Abstract
BACKGROUND 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
BACKGROUND 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 < 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
BACKGROUND The COVID-19 pandemic caused disruption of regular healthcare leading to reduced hospital attendances, repurposing of surgical facilities, and cancellation of cancer screening programmes. This study aimed to determine the impact of COVID-19 on surgical care in the Netherlands. METHODS A nationwide study was conducted in collaboration with the Dutch Institute for Clinical Auditing. Eight surgical audits were expanded with items regarding alterations in scheduling and treatment plans. Data on procedures performed in 2020 were compared with those from a historical cohort (2018-2019). Endpoints included total numbers of procedures performed and altered treatment plans. Secondary endpoints included complication, readmission, and mortality rates. RESULTS Some 12 154 procedures were performed in participating hospitals in 2020, representing a decrease of 13.6 per cent compared with 2018-2019. The largest reduction (29.2 per cent) was for non-cancer procedures during the first COVID-19 wave. Surgical treatment was postponed for 9.6 per cent of patients. Alterations in surgical treatment plans were observed in 1.7 per cent. Time from diagnosis to surgery decreased (to 28 days in 2020, from 34 days in 2019 and 36 days in 2018; P < 0.001). For cancer-related procedures, duration of hospital stay decreased (5 versus 6 days; P < 0.001). Audit-specific complications, readmission, and mortality rates were unchanged, but ICU admissions decreased (16.5 versus 16.8 per cent; P < 0.001). CONCLUSION The reduction in the number of surgical operations was greatest for those without cancer. Where surgery was undertaken, it appeared to be delivered safely, with similar complication and mortality rates, fewer admissions to ICU, and a shorter hospital stay.

Abstract
Optimal surgical treatment for Siewert type II esophagogastric junction adenocarcinoma is debated. The aim of this study was to compare transhiatal extended gastrectomy (TEG) and transthoracic esophagectomy (TTE). Patients with Siewert type II tumors who underwent a resection by TEG or TTE in two centers (Erasmus University Medical Center, Rotterdam, and University of Verona) between 2014 and 2019 were identified. To limit selection bias, patients were matched for baseline characteristics and compared with a multivariable logistic regression model. Some 159 patients treated by TEG (60 patients, 37.7%) or TTE (99 patients, 62.3%) were included. Patients in the TEG group were older, had less tumor invasion of the esophagus, and were more often excluded from neoadjuvant therapy. Post-operative morbidity was comparable (P = 0.88), while 90-day mortality was higher after TEG (90-day mortality 10.0% in TEG group vs. 2.0% in TTE group P = 0.01). R0 resection was achieved in 83.3% of patients after TEG and in 97.9% after TTE (P < 0.01), with the proximal resection margin involved in 16.6% of patients after TEG versus 0 in TTE group (P < 0.01). The 3-year overall survival was comparable (TEG: 36.5%, TTE: 48.4%, P = 0.12). At multivariable analysis, (y)pT category was an independent risk factor for 3-year recurrence. After matching, TEG was still associated with an increased risk of incomplete tumor resection (P = 0.03) and proximal margin involvement (P < 0.01), while there were no differences in post-operative morbidity (P = 0.56) and mortality (P = 0.31). Our data suggest that patients with Siewert type II tumors treated by TEG are exposed to a higher risk of positive proximal resection margin compared to TTE.

Chemotherapy aNd chemoradiotherapy for adenocarcinoma of the OESophagus and esophagogastric junction with oligometastases: Protocol of the TNT-OES-1 trial. Contemp Clin Trials Commun 2022; 28:100934. [PMID: 35669486 PMCID: PMC9163410 DOI: 10.1016/j.conctc.2022.100934] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2021] [Revised: 03/25/2022] [Accepted: 05/25/2022] [Indexed: 02/07/2023] Open
Abstract
Background FLOT and CROSS are effective neoadjuvant regimens for esophageal cancer patients. Chemotherapy (FLOT) is aimed to have merely a systemic effect whereas neoadjuvant chemoradiotherapy (CROSS) achieves good locoregional response with clinically complete response (cCR) rates up to 33% [1]. The aim of the present study is to assess safety and feasibility of dual therapy (FLOT-CROSS) in patients with oligometastases. Methods This phase-II single-center, single-arm, intervention study includes patients with oligometastatic adenocarcinoma of the esophagus or esophagogastric junction. Patients will be treated with four biweekly cycles of FLOT, consisting of intravenous fluorouracil (2600 mg/m2), leucovorin (200 mg/m2), oxaliplatin (85 mg/m2) and docetaxel (50 mg/m2). Response evaluation by CT-scan will be performed 4-6 weeks after completion of FLOT. In case of regression or stable disease according to RECIST criteria (v.1.1), patients will receive additional CROSS, consisting of five weekly cycles of intravenous carboplatin (AUC 2) and paclitaxel (50 mg/m2), with concurrent 41.4 Gy radiotherapy, in 23 daily fractions of 1.8 Gy [2]. Response evaluation by endoscopy with biopsies, endoscopic ultrasonography and CT-scan will be performed 4-6 weeks after completion of CROSS. Primary endpoint is tolerability of FLOT-CROSS, defined as the proportion of patients who complete the full regimen. Secondary endpoints include disease control rate, objective response rate, overall survival and progression-free survival. In total, 20 patients will be included. Discussion If patients are able to complete and tolerate FLOT-CROSS, this regimen should be tested in a phase-III trial and as neoadjuvant treatment in patients with locally advanced non-metastatic esophageal or junctional adenocarcinoma.

Survival trends of patients with non-metastatic gastric adenocarcinoma in the US and European countries: the impact of decreasing resection rates. Cancer Commun (Lond) 2022; 42:648-662. [PMID: 35666080 PMCID: PMC9257984 DOI: 10.1002/cac2.12318] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2021] [Revised: 03/13/2022] [Accepted: 05/26/2022] [Indexed: 12/17/2022] Open
Abstract
BACKGROUND We previously observed decreasing resection rates of non-metastatic gastric adenocarcinoma (GaC) in the US and some European countries. If and to what extent these trends affect the trends in overall survival (OS) of patients with non-metastatic GaC at the population level remain unclear. This large international population-based cohort study aimed to assess the impact of the previously observed decreasing resection rates on multivariable-adjusted trends in the long-term OS of patients with non-metastatic GaC. METHODS Individual-level data of patients with non-metastatic GaC were obtained from the national cancer registries of the Netherlands, Belgium, Sweden, Norway, and Slovenia, and the US Surveillance, Epidemiology, and End Results database. We analyzed data for each country separately. Associations between year of diagnosis and OS were assessed using Cox proportional hazards regression model with adjustment for multiple prognostic variables, with and without including resection and chemotherapy as potential explanatory variables. RESULTS A total of 66,398 non-metastatic GaC patients diagnosed in 2003-2016 were analyzed, with an accumulated follow-up of 172,357 person-years. Without adjustment for resection, OS was improved only slightly in the US [hazard ratio (HR)per year = 0.99; HR≥ vs. <2010 = 0.96], and no improvement was observed in the investigated European countries, with OS even worsening in Sweden (HRper year = 1.03; HR≥ vs. <2010 = 1.17). After adjusting for resection, the increasing OS trend became stronger in the US (HRper year = 0.98; HR≥ vs. <2010 = 0.88), and the temporal trend became insignificant in Sweden. In Slovenia (HRper year = 0.99; HR≥ vs. <2010 = 0.92) and Norway (HRper year = 0.97; HR≥ vs. <2010 = 0.86), improved OS over time emerged after resection adjustment. Improved OS in patients undergoing resection was observed in the US, the Netherlands, and Norway. Adjustment for chemotherapy did not alter the observed associations. Stratified analyses by tumor location showed mostly similar results with the findings in all patients with non-metastatic GaCs regarding the associations between year of diagnosis and survival. CONCLUSIONS OS of patients with non-metastatic GaC mostly did not improve in selected European countries and was even worsened in Sweden, while it was slightly increased in the US in the early 21st century. Progress in OS of patients with non-metastatic GaC seems to have been impeded to a large extent by decreasing rates of resection.

Abstract
Abstract
Background
Textbook outcome has been proposed as a tool for the assessment of oncological surgical care. However, an international assessment in patients undergoing oesophagectomy for oesophageal cancer has not been reported. This study aimed to assess textbook outcome in an international setting.
Methods
Patients undergoing curative resection for oesophageal cancer were identified from the international Oesophagogastric Anastomosis Audit (OGAA) from April 2018 to December 2018. Textbook outcome was defined as the percentage of patients who underwent a complete tumour resection with at least 15 lymph nodes in the resected specimen and an uneventful postoperative course, without hospital readmission. A multivariable binary logistic regression model was used to identify factors independently associated with textbook outcome, and results are presented as odds ratio (OR) and 95 per cent confidence intervals (95 per cent c.i.).
Results
Of 2159 patients with oesophageal cancer, 39.7 per cent achieved a textbook outcome. The outcome parameter ‘no major postoperative complication’ had the greatest negative impact on a textbook outcome for patients with oesophageal cancer, compared to other textbook outcome parameters. Multivariable analysis identified male gender and increasing Charlson comorbidity index with a significantly lower likelihood of textbook outcome. Presence of 24-hour on-call rota for oesophageal surgeons (OR 2.05, 95 per cent c.i. 1.30 to 3.22; P = 0.002) and radiology (OR 1.54, 95 per cent c.i. 1.05 to 2.24; P = 0.027), total minimally invasive oesophagectomies (OR 1.63, 95 per cent c.i. 1.27 to 2.08; P < 0.001), and chest anastomosis above azygous (OR 2.17, 95 per cent c.i. 1.58 to 2.98; P < 0.001) were independently associated with a significantly increased likelihood of textbook outcome.
Conclusion
Textbook outcome is achieved in less than 40 per cent of patients having oesophagectomy for cancer. Improvements in centralization, hospital resources, access to minimal access surgery, and adoption of newer techniques for improving lymph node yield could improve textbook outcome.
