Management of Uveal Melanoma: Updated Cancer Care Alberta Clinical Practice Guideline.

OBJECTIVE: The purpose of this guideline update is to reassess and update recommendations in the prior guideline from 2016 on the appropriate management of patients with uveal melanoma. METHODS: In 2021, a multidisciplinary working group from the Provincial Cutaneous Tumour Team, Cancer Care Alberta, Alberta Health Services was convened to update the guideline. A comprehensive review of new research evidence in PubMed as well as new clinical practice guidelines from prominent oncology groups informed the update. An enhancement in methodology included adding levels of evidence and strength of recommendations. The updated guideline was circulated to all members of the Provincial Cutaneous Tumour Team for review and endorsement. RESULTS: New and modified recommendations address provider training requirements, diagnostic imaging for the detection of metastases, neo-adjuvant pre-enucleation radiotherapy, intravitreal anti-vascular endothelial growth factor agents for radiation retinopathy, genetic prognostic testing, surveillance following definitive local therapy, and systemic therapy for patients with metastatic uveal melanoma. DISCUSSION: The recommendations represent evidence-based standards of care agreed to by a large multidisciplinary group of healthcare professionals.

Unwarranted imaging for distant metastases in patients with newly diagnosed ductal carcinoma in situ and stage I and II breast cancer

Background: In 2012, the American Society of Clinical Oncology (ASCO) released a Choosing Wisely Top Five list that included a recommendation against ordering advanced imaging tests to screen for metastases among asymptomatic patients with early breast cancer. Our provincial breast cancer staging guideline was subsequently updated. We report on the use of unwarranted bone scanning (BS), computed tomography (CT), nonbreast magnetic resonance imaging (MRI) and positron emission tomography (PET) among women diagnosed with stage 0­II breast cancer in Alberta in 2011­2015. Methods: The cohort was retrospectively ascertained from the Alberta Cancer Registry. We used additional provincial data sources to obtain information about diagnostic imaging tests completed from biopsy to surgical date plus 4 months. The reason for each BS, CT, MRI and PET was abstracted. We calculated the frequency of advanced imaging tests completed for routine metastatic screening. Results: Of 10 142 patients included, 2887 (28.5%) had at least 1 advanced imaging test completed for routine metastatic screening. Of these 2887 patients, 438 (15.2%) had a follow-up BS, CT, MRI or PET, and 28 patients (1.0%) had a nonbreast imageguided biopsy. Use of routine advanced imaging tests did not change clearly over time. Conclusion: Our results demonstrate persistent use of advanced imaging tests for routine metastatic screening among patients with stage 0­II breast cancer despite the release of the ASCO Choosing Wisely recommendations and the update of our provincial breast cancer staging guideline. Investigation of strategies for guideline translation to improve upon value-based care of patients with early breast cancer is warranted.

Contexte: En 2012, l'American Society of Clinical Oncology (ASCO) a publié sa liste de 5 interventions à « Choisir avec soin ¼, dans laquelle elle recommandait notamment de ne pas recourir aux techniques d'imagerie de pointe pour le dépistage des métastases chez les patientes atteintes d'un cancer du sein peu avancé et asymptomatique. Nos lignes directrices provinciales pour la stadification du cancer du sein ont été mises à jour en conséquence. Nous faisons aujourd'hui état de l'utilisation injustifiée de la scintigraphie osseuse (SO), de la tomodensitométrie (TDM), de l'imagerie par résonnance magnétique (IRM) non mammaire et de la tomographie par émission de positrons (TEP) chez les femmes ayant reçu un diagnostic de cancer du sein peu avancé (stade 0-II) en Alberta entre 2011 et 2015. Méthodes: La cohorte a été réunie de manière rétrospective à partir du registre albertain du cancer. Nous avons utilisé d'autres sources de données provinciales pour obtenir des renseignements sur les épreuves d'imagerie diagnostique effectuées entre les dates de la biopsie et les dates de la chirurgie plus 4 mois. Le motif invoqué pour recourir à chaque SO, TDM, IRM et TEP a été recueilli. Nous avons calculé la fréquence des épreuves d'imagerie de pointe effectuées pour un dépistage de routine des métastases. Résultats: Sur les 10 142 patientes incluses, 2887 (28,5 %) avaient subi au moins 1 épreuve d'imagerie de pointe pour le dépistage de routine des métastases. Parmi ces 2887 patientes, 438 (15,2 %) ont subi une SO, une TDM, une IRM ou une TEP de suivi et 28 patientes (1,0 %) ont subi une biopsie non mammaire guidée par l'imagerie. L'utilisation de routine des épreuves d'imagerie de pointe n'a pas nettement changé avec le temps. Conclusion: Selon nos résultats, l'utilisation des épreuves d'imagerie de pointe pour le dépistage de routine des métastases persiste chez les patientes atteintes d'un cancer du sein de stade 0­II, malgré la publication des recommandations Choisir avec soin de l'ASCO et la mise à jour de nos lignes directrices provinciales concernant la stadification du cancer du sein. Il faudra se pencher sur des stratégies pour améliorer l'adoption de lignes directrices relatives aux soins véritablement utiles pour les patientes atteintes d'un cancer du sein peu avancé.

Development of a clinical pathway for enhanced recovery in colorectal surgery: a Canadian collaboration

Summary: Enhanced Recovery After Surgery (ERAS) is a model of care that was introduced in the late 1990s by a group of surgeons in Europe. The model consists of a number of evidence-based principles that support better outcomes for surgical patients, including improved patient experience, reduced length of stay in hospital, decreased complication rates and fewer hospital readmissions. A number of Canadian surgical care teams have already adopted ERAS principles and have reported positive outcomes. Arising from the Canadian Patient Safety Institute's Integrated Patient Safety Action Plan for Surgical Care Safety, and with support from numerous partner organizations from across the country, Enhanced Recovery Canada is leading the drive to improve surgical safety across the country and help disseminate these ERAS principles. We discuss the development of a multidisciplinary clinical pathway for elective colorectal surgery to help guide Canadian clinicians.

University students' hand hygiene practice during a gastrointestinal outbreak in residence: what they say they do and what they actually do.

Published research on outbreaks of gastrointestinal illness has focused primarily on the results of epidemiological and clinical data collected postoutbreak; little research has been done on actual preventative practices during an outbreak. In this study, the authors observed student compliance with hand hygiene recommendations at the height of a suspected norovirus outbreak in a university residence in Ontario, Canada. Data on observed practices was compared to postoutbreak self-report surveys administered to students to examine their beliefs and perceptions about hand hygiene. Observed compliance with prescribed hand hygiene recommendations occurred 17.4% of the time. Despite knowledge of hand hygiene protocols and low compliance, 83.0% of students indicated that they practiced correct hand hygiene during the outbreak. To proactively prepare for future outbreaks, a current and thorough crisis communications and management strategy, targeted at a university student audience and supplemented with proper hand washing tools, should be enacted by residence administration.
