Abstract
Background Gastrectomy with negative resection margins and adequate lymph node dissection is the cornerstone of curative treatment for gastric cancer (gc). However, gastrectomy is a complex and invasive operation with significant morbidity and mortality. Little is known about surgical practice patterns or short- and long-term outcomes in early-stage gc in Canada. Methods We undertook a population-based retrospective cohort study of patients with gc diagnosed between 1 April 2005 and 31 March 2008. Chart review provided clinical and operative details such as disease stage, primary tumour location, surgical approach, operation, lymph nodes, and resection margins. Administrative data provided patient demographics, geography, and vital status. Variations in treatment and outcomes were compared for 14 local health integration networks. Descriptive statistics and log-rank tests were used to examine geographic variation. Results We identified 722 patients with nonmetastatic resected gc. We documented significant provincial variation in case mix, including primary tumour location, stage at diagnosis, and tumour grade. Short-term surgical outcomes varied across the province. The percentage of patients with 15 or fewer lymph nodes removed and examined varied from 41.8% to 73.8% (p = 0.02), and the rate of positive surgical margins ranged from 15.2% to 50.0% (p = 0.002). The 30-day surgical mortality rates did not vary statistically significantly across the province (p = 0.13); however, rates ranged from 0% to 16.7%. Overall 5-year survival was 44% and ranged from 31% to 55% across the province. Conclusions This cohort of patients with resected stages i-iii gc is the largest analyzed in Canada, providing important historical information about treatment outcomes. Understanding the causes of regional variation will support interventions aiming to improve gc operative outcomes in the cancer system.

Quality of Endoscopy Reports for Esophageal Cancer Patients: Where Do We Stand? J Gastrointest Surg 2018; 22:778-784. [PMID: 29508217 PMCID: PMC5988358 DOI: 10.1007/s11605-018-3710-4] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/30/2017] [Accepted: 02/05/2018] [Indexed: 01/31/2023]
Abstract
BACKGROUNDS AND AIMS As treatment for esophageal cancer often involves a multidisciplinary approach, the initial endoscopic report is essential for communication between providers. Several guidelines have been established to standardize endoscopic reporting. This study evaluates the compliance of esophagogastroduodenoscopy (EGD) and endoscopic ultrasound (EUS) reporting with the current national guidelines. METHODS Combining the National Comprehensive Cancer Network and Society of Thoracic Surgeons guidelines, 11 quality indicators (QIs) for EGD and 8 for EUS were identified. We evaluated initial EGD and EUS reports from our institution (Memorial Sloan Kettering [MSK]) and outside hospitals (OSHs) and calculated individual and overall quality measure scores. Scores between locations were compared using the Wilcoxon signed-rank test and McNemar's test for paired data. RESULTS In total, 115 initial EGD reports and 105 EUS reports were reviewed for patients who underwent surgery for esophageal cancer between 2014 and 2016. The median number of QIs reported for the initial EGD was 4 (IQR, 3-6)-only 34% of reports qualified as "good quality" (those with ≥ 6 QIs). None of the reports included all QIs. For patients who underwent EGD at both MSK and an OSH, 32% of reports from OSHs were good quality, compared with 68% from MSK (p < 0.001). Compliance with QIs was better for EUS reports: 71% of OSH reports and 72% of MSK reports were good quality. CONCLUSIONS Detailed information on the initial endoscopic assessment is essential in today's age of multidisciplinary care. Identification and adoption of QIs for endoscopic reporting is warranted to ensure the provision of appropriate treatment.
