Background: Quality performance indicators (QPI) are objective measurements of aspects of patient care that affect clinical outcome. This study investigates the compliance rate to published QPIs of gastric adenocarcinoma (GA) management, in a single institution, to determine areas of strong performance and those requiring improvement., Methods: All patients with GA treated from 2010 to 2015, and 2020 to 2021 were included. Electronic data in the form of clinic letters, operation notes, and histology and radiology reports were reviewed with ethics approval. QPI adherence was collected in binary form., Results: QPIs with high compliance rate include preoperative radiological staging and histological diagnosis, subspecialty surgeon training and pathology report documentation. QPIs with low compliance include perioperative chemotherapy (31.6%), postoperative radiological surveillance (32.5%) and minimally invasive approaches to surgical resection (12.5%)., Conclusions: QPIs from the systematic review are variably implemented in clinical practice, thus informing on their relevance to real world clinical practice whilst also identifying the areas requiring focus for improvement., (© 2023 Royal Australasian College of Surgeons.)

Background: A systematic review was undertaken to identify existing quality performance indicators (QPI) for the surgical treatment of gastric adenocarcinoma (GA) with the aim of defining a set of QPIs that can be used to assist in the accreditation of institutions for training, allow cross jurisdiction comparison of treatment and outcomes, as well as provide a basis to develop quality improvement programs. These QPI's capture key components of patient care that are fundamental to overall outcome., Methods: A systematic literature review was conducted searching MEDLINE, PubMed, EMBASE, and SCOPUS with all literature available until the date of 1 August 2021 included. Search terms utilized were 'Quality of health care OR Quality improvement or Quality control OR Quality indicators', AND 'Gastrectomy' OR 'Stomach neoplasm' OR 'Adenocarcinoma' OR 'Gastric resection' OR 'Gastric cancer'., Results: Twelve articles were included in the final analysis. The selected studies included editorials (n = 2), retrospective review of institutional experience (n = 5), cohort studies (n = 2), survey methodology (n = 1), expert guidelines (n = 1) and consensus statement (n = 1). For GC QPIs, process measures included patient discussion at multi-disciplinary meetings, access to perioperative multimodal diagnostic pathways, and specific surgical metrics (margin negative resections and adequate lymphadenectomy). Outcome measures included the RO resection rate, reoperation, readmission rate, and length of hospital stay., Conclusions: There is a relative paucity of internationally agreed QPI for the surgical management of gastric adenocarcinoma. The data from this review will form the basis of a project to develop internationally agreed and feasible QPI for gastric cancer resections., (© 2022 The Authors ANZ Journal of Surgery published by John Wiley & Sons Australia, Ltd on behalf of Royal Australasian College of Surgeons.)

Background: Surgical treatment of gastric cancer in New Zealand is challenging because of a low annual incidence of 400 patients and population dispersal over a wide area with little data on regional treatment trends and outcomes. This investigation was undertaken to evaluate the surgical outcomes of gastric cancer patients presenting to a single upper gastrointestinal centre (WDHB, Waitemata District Health Board) and to compare these to national and international standards., Methods: Data on 135 patients with histologically proven gastric adenocarcinoma presenting between January 2010 and December 2014 were reviewed and compared with nationally available procedural volume data., Results: Sixty of 135 patients were resected (resection rate 44%) and 75 patients were managed with palliative chemotherapy/symptomatic care alone. Twenty-six patients (43%) received adjuvant or neoadjuvant chemotherapy and only two patients (3%) underwent laparoscopic resection. In resected patients, 90-day mortality was 1.6%, and 11 patients (18%) developed complications ≥ Clavien-Dindo grade 3. Fifty-two patients (87%) had ≥15 lymph nodes resected and 54 patients (90%) had a histological R 0 resection. At median follow-up of 49 months, 30 patients remain alive and disease-free with 20 true 5-year disease-free survivors. National data between 2010 and 2014 showed WDHB performed 20% (338/1710) of gastric resections for all indications in New Zealand., Conclusion: While WDHB is an internationally low volume centre for gastric cancer, surgical outcomes benchmark satisfactorily to international standards. New Zealand's national treatment standards should set aspirational goals for gastric cancer treatment and have a clear strategy to address issues of surgical volume and national service provision., (© 2019 Royal Australasian College of Surgeons.)

Background: This study aims to define contemporary trends in characteristics, costs and management of patients diagnosed with oesophageal adenocarcinoma in New Zealand., Methods: Clinical, pathological and management data of the 135 patients presenting with histologically proven adenocarcinoma to our institution over a 5-year period (January 2010 to December 2014) was collected. Primary analysis reviewed patient demographics, co-morbidities, treatment strategy and survival. Secondary analysis defined operative outcomes including complications, mortality rates and overall survival to December 2016., Results: Thirty-eight patients underwent oesophago-gastrectomy (resection rate 28%) with curative intent following neoadjuvant chemotherapy with Clavien-Dindo ≥3 complications in 17 patients (46%). Actuarial survivals from surgery at 1, 3 and 5 years were (79, 55 and 50%), with 19 patients (54%) alive and disease free at a median follow-up of 26.5 months (range 1-82 months). Overall, this represented one sixth of the national volume of oesophagectomy. Ninety-seven patients were managed non-surgically due to metastatic or advanced local disease (n = 64), co-morbid status (n = 27), patients choice (n = 2) and unknown (n = 4). Median survival from diagnosis in non-resected patients was 9 months (range 1-40 months)., Conclusion: Oesophagectomy remains a challenging procedure for any institution, although good results can be achieved. Foci for referral are emerging in New Zealand for the surgical management of oesophageal cancer., (© 2018 Royal Australasian College of Surgeons.)

Introduction: The aim of present paper was to document the incidence of gall bladder cancer, cancer of the extrahepatic bile ducts and ampullary carcinoma in New Zealand., Methods: Data were collected from the New Zealand Cancer Registry from 1980 to 1997 and combined with national census statistics to give crude and age standardized incidence rates., Results: Over the 18-year study period, 226 carcinomas of the ampulla of Vater, 608 gall bladder cancers, and 486 extrahepatic cholangiocarcinomas were registered. The age standardized incidence rates for gall bladder carcinoma in all New Zealanders were 0.41/100 000 in men and 0.74/100 000 in women. The age standardized incidence rates for gall bladder cancer in Maori were 1.49/100 000 in Maori men and 1.59/100 000 in Maori women. The corresponding age standardized incidence rates for extrahepatic bile duct cancers were 0.67/100 000 in men and 0.45/100 000 in women. There were insufficient cases to calculate an age standardized incidence in Maori or Pacific Islanders. For carcinoma of the ampulla, the age standardized rates were 0.34/100 000 in men and 0.25/100 000 in women. There were insufficient cases to calculate an age standardized incidence rate for Maori or Pacific Islanders. When histology was defined adenocarcinoma was the most common form of cancer occurring in 66% of gall bladder cancers, 91% of extrahepatic bile duct cancers and 70% of ampullary cancers. Most tumours were advanced at presentation with regional or distant metastases present in 72% of gall bladder cancers, 63% of extrahepatic bile duct cancers and 69% of ampullary tumours at diagnosis. Survival was poor with median survivals of 86 days, 151 days and 440 days recorded for gall bladder cancer, extrahepatic bile duct cancer and ampullary cancer, respectively., Conclusions: The demographic profile, pathology and survival of patients with gall bladder cancer, extrahepatic bile duct cancer and ampullary carcinoma are similar in New Zealand to that of other Western countries. However New Zealand Maori have a relatively high incidence of gall bladder cancer, and the incidence is equal in both Maori men and women, while cancers of the extra-hepatic bile duct and ampulla of Vater are rare in Maori. In comparison, cancers of the gall bladder, extrahepatic bile ducts and ampulla are rare in Pacific Islanders.

Background Oesophageal adenocarcinoma (OAC) is a lethal condition. The management is typically multifaceted with oesophagectomy being the cornerstone of treatment. Quality performance indicators (QPIs) are objective measurements of aspects of patient's care that affect clinical outcomes. We look to measure a set of clinically relevant QPIs that can be used to capture key aspects of patient management at our institution. Methods all patients with OAC treated from 2010 to 2015, and 2020 to 2021 at Te Whatu Ora Waitemata were included. Patients with secondary metastases to the oesophagus or gastric cancer with extension to the oesophagus were excluded. Electronic data in the form of clinic letters, operation notes, histology and radiology reports were reviewed. QPI adherence was collected in binary form. Results QPIs with consistently high compliance rates include radiological staging and histological diagnosis, perioperative dietitian involvement, explanations of disease and treatment intent, and pathology report documentation. QPIs demonstrating significant change and improvement across the two groups include endoscopic resection (60.0% of patients with T1 disease in 2010 to 88.9% in 2020 group), multimodality treatment (majority ECF and ECX perioperative chemotherapy in 2010 to majority FLOT chemotherapy in 2020 group) and minimally invasive approach (30.4% hybrid in 2010 compared to 72.4% hybrid in 2020). Conclusions QPIs from the systematic review were readily measurable and were variably implemented in clinical practice. Areas requiring improvement were identified however relevance to real-world clinical outcomes require further focus of investigation. [ABSTRACT FROM AUTHOR]
