Reorganizing the Multidisciplinary Team Meetings in a Tertiary Centre for Gastro-Intestinal Oncology Adds Value to the Internal and Regional Care Pathways. A Mixed Method Evaluation

Introduction: The reorganisation of the structure of a Gastro-Intestinal Oncology Multidisciplinary Team Meeting (GIO-MDTM) in a tertiary centre with three care pathways is evaluated on added value. Methods: In a mixed method investigation, process indicators such as throughput times were analysed and stakeholders were interviewed regarding benefits and drawbacks of the reorganisation and current MDTM functioning. Results: For the hepatobiliary care pathway, the time to treatment plan increased, but the time to start treatment reduced significantly. The percentage of patients treated within the Dutch standard of 63 days increased for the three care pathways. From the interviews, three themes emerged: added value of MDTMs, focus on planning integrated care and awareness of possible improvements. Discussion: The importance of evaluating interventions in oncology care pathways is shown, including detecting unexpected drawbacks. The evaluation provides insight into complex dynamics of the care pathways and contributes with recommendations on functioning of an MDTM. Conclusions: Throughput times are only partly determined by oncology care pathway management, but have influence on the functioning of MDTMs. Process indicator information can help to reflect on integration of care in the region, resulting in an increase of patients treated within the Dutch standard

Impact of nationwide enhanced implementation of best practices in pancreatic cancer care (PACAP-1): A multicenter stepped-wedge cluster randomized controlled trial

Background: Pancreatic cancer has a very poor prognosis. Best practices for the use of chemotherapy, enzyme replacement therapy, and biliary drainage have been identified but their implementation in daily clinical practice is often suboptimal. We hypothesized that a nationwide program to enhance implementation of these best practices in pancreatic cancer care would improve survival and quality of life. Methods/design: PACAP-1 is a nationwide multicenter stepped-wedge cluster randomized controlled superiority trial. In a per-center stepwise and randomized manner, best practices in pancreatic cancer care regarding the use of (neo)adjuvant and palliative chemotherapy, pancreatic enzyme replacement therapy, and metal biliary stents are implemented in all 17 Dutch pancreatic centers and their regional referral networks during a 6-week initiation period. Per pancreatic center, one multidisciplinary team functions as reference for the other centers in the network. Key best practices were identified from the literature, 3 years of data from existing nationwide registries within the Dutch Pancreatic Cancer Project (PACAP), and national expert meetings. The best practices follow the Dutch guideline on pancreatic cancer and the current state of the literature, and can be executed within daily clinical practice. The implementation process includes monitoring, return visits, and provider feedback in combination with education and reminders. Patient outcomes and compliance are monitored within the PACAP registries. Primary outcome is 1-year overall survival (for all disease stages). Secondary outcomes include quality of life, 3- and 5-year overall survival, and guideline compliance. An improvement of 10% in 1-year overall survival is considered clinically relevant. A 25-month study duration was chosen, which provides 80% statistical power for a mortality reduction of 10.0% in the 17 pancreatic cancer centers, with a required sample size of 2142 patients, corresponding to a 6.6% mortality reduction and 4769 patients nationwide. Discussion: The PACAP-1 trial is designed to evaluate whether a nationwide program for enhanced implementation of best practices in pancreatic cancer care can improve 1-year overall survival and quality of life. Trial registration: ClinicalTrials.gov, NCT03513705. Trial opened for accrual on 22th May 2018

Long-term follow-up results of stepwise radical endoscopic resection for Barrett's esophagus with early neoplasia

BACKGROUND AND AIMS: Stepwise radical endoscopic resection (SRER) has shown to be effective in eradicating Barrett's esophagus (BE) and its associated dysplasia. The aim of this study was to assess the long-term durability after successful SRER for early Barrett's neoplasia. METHODS: Patients treated with SRER for BE ≤5 cm with high-grade dysplasia (HGD) or early cancer (EC) and who had reached complete eradication of intestinal metaplasia (CE-IM) and neoplasia (CE-neo) were included. Primary outcomes were recurrence of neoplasia (HGD/EC), recurrence of dysplasia (indefinite for dysplasia included), and recurrence of endoscopically visible BE. Secondary outcomes were buried Barrett's glands, IM in biopsy specimens obtained distal to a normal-appearing neo-squamocolumnar junction (neo-SCJ), need for retreatment, and sustained CE-IM and CE-neo at the last follow-up endoscopy. RESULTS: Seventy-three patients were included (64 men; mean age, 66 years; median BE, C2M3). Median follow-up was 76 months. Recurrence of neoplasia was observed in 1 patient (T1bN0M0) after 129 months of follow-up and was treated with curative surgery (annual incidence of .22% per patient-year of follow-up). In 4 patients, recurrence of dysplasia was found (.87% per patient-year of follow-up). Twelve patients had recurrent endoscopically visible BE after a median follow-up of 22 months (2.6% per patient-year of follow-up), mostly small islands or tongues. Five patients had a single finding of buried Barrett's glands (1.1% per patient-year of follow-up), and 27 patients (5.9% per patient-year of follow-up) showed IM in biopsy specimens just distal to the neo-SCJ, which was not reproduced in 56%. Retreatment was performed in 9 patients. CE-IM and CE-neo (excluding IM in the neo-SCJ) at the last follow-up endoscopy was seen in 95% and 97% of patients, respectively. CONCLUSIONS: This study presents the longest published follow-up data on SRER to date. The 6-year outcomes show that successful SRER is a durable treatment for BE ≤5 cm with HGD/EC

Learning endoscopic resection in the esophagus

Background: Endoscopic resection is the cornerstone of endoscopic management of esophageal early neoplasia. However, endoscopic resection is a complex technique requiring knowledge and expertise. Our aims were to identify the most important learning points in performing endoscopic resection in a training setting and to provide information on how to improve endoscopic resection technique. Methods: Six gastroenterologists at centers with multidisciplinary expertise in upper gastrointestinal oncology participated in a structured endoscopic resection training program, consisting of four training days with lectures and hands-on training on live pigs, further one-to-one hands-on training days, and written feedback (by an expert) on videos of unsupervised endoscopic resection procedures. The first 20 endoscopic resections of each participant were prospectively registered. Ninety learning points were independently identified by participants using a standardized questionnaire and by an expert providing written feedback on 33 unsupervised endoscopic resection videos. Three expert endoscopists selected and ranked the most important learning points in a consensus meeting. Results. The top 10 tips (illustrated by unique videos of three perforations) were: (1) allow time for inspection and use a high-definition endoscope; (2) create a preprocedural plan by placing electrocoagulation markings; (3) know the management of bleeding; (4) optimize the endoscopic view by repeatedly cleaning out stomach and target area; (5) use a therapeutic endoscope during resection; (6) always perform a test suction; (7) keep instruments close to the tip; (8) lift edges in piecemeal endoscopic cap resections; (9) know the management of perforation; (10) pin specimens down. Conclusions: This study summarized the most important learning points for performing endoscopic resection encountered during a structured endoscopic resection training program

A simplified regimen for focal radiofrequency ablation of Barrett's mucosa: a randomized multicenter trial comparing two ablation regimens

BACKGROUND: The currently recommended regimen for focal radiofrequency ablation (RFA) of Barrett's esophagus (BE) comprises 2 applications of energy, cleaning of the device and ablation zone, and 2 additional applications of energy. A simplified regimen may be of clinical utility if it is faster, easier, and equally safe and effective. OBJECTIVE: To compare the efficacy of 2 focal RFA regimens. SETTING: Three tertiary referral centers. PATIENTS: Consecutive patients scheduled for focal RFA of BE with flat type BE with at least 2 BE islands or mosaic groups of islands were enrolled. INTERVENTIONS: BE areas were paired: 1 area was randomized to the "standard" regimen (2 × 15 J/cm(2)-clean-2 × 15 J/cm(2)) or to the "simplified" regimen (3 × 15 J/cm(2)-no clean), allocating the second area automatically to the other regimen. The percentage of surface area regression of each area was scored at 2 months by the endoscopist (blinded). OUTCOME MEASURE: Proportion of completely removed BE areas at 2 months. Calculated sample size was 46 pairs of BE areas using a noninferiority design. Noninferiority was defined as <20% difference in the paired proportions. RESULTS: Forty-five equivalent pairs of BE areas were included in 41 patients. The proportion of completely removed BE areas at 2 months after focal RFA was 30 (67%) for standard and 33 (73%) for simplified. Noninferiority was demonstrated by a 7% difference (95% CI, -10.6 to +20.9). LIMITATIONS: Tertiary referral centers. CONCLUSIONS: The results of this multicenter randomized trial suggest that a simplified 3 × 15 J/cm(2) focal ablation regimen is not inferior to the standard regimen, regarding the endoscopic removal of residual Barrett islands

Remission of Barrett's esophagus with early neoplasia 5 years after radiofrequency ablation with endoscopic resection: a Netherlands cohort study

Radiofrequency ablation (RFA), with or without endoscopic resection effectively eradicates Barrett's esophagus (BE) containing high-grade intraepithelial neoplasia and/or early-stage cancer. We followed patients who received RFA for BE containing high-grade intraepithelial neoplasia and/or early-stage cancer for 5 years to determine the durability of treatment response. We followed 54 patients with BE (2-12 cm), previously enrolled in 4 consecutive cohort studies in which they underwent focal endoscopic resection in case of visible lesions (n = 40 [72%]), followed by serial RFA every 3 months. Patients underwent high-resolution endoscopy with narrow-band imaging at 6 and 12 months after treatment and then annually for 5 years (median, 61 months; interquartile range, 53-65 months); random biopsy samples were collected from neosquamous epithelium and gastric cardia. After 5 years, endoscopic ultrasound and endoscopic resection of neosquamous epithelium were performed. Outcomes included sustained complete remission of neoplasia or intestinal metaplasia (IM), IM in gastric cardia, or buried glands in neosquamous epithelium. After 5 years, Kaplan-Meier analysis showed sustained complete remission of neoplasia and intestinal metaplasia in 90% of patients; neoplasia recurred in 3 patients and was managed endoscopically. Focal IM in the cardia was found in 19 of 54 patients (35%), in 53 of 1143 gastric cardia biopsies (4.6%). The incidence of IM of the cardia did not increase over time; and IM was diagnosed based on only a single biopsy in 89% of patients. Buried glands were detected in 3 of 3543 neosquamous epithelium biopsies (0.08%, from 3 patients). No endoscopic resection samples had buried glands. Among patients who have undergone RFA with or without endoscopic resection for neoplastic BE, 90% remain in remission at 5-year follow-up, with all recurrences managed endoscopically. This treatment approach is therefore an effective and durable alternative to esophagectomy; www.trialregister.nl number, NTR293
