RESUMO
Summary: During the coronavirus disease 2019 (COVID-19) pandemic, delaying lifesaving cancer surgeries must be done with extreme caution and thoughtfulness. Modelling indicates that delays in high-risk cancer surgeries beyond 6 weeks could affect long-term outcomes for thousands of Canadians. Consequently, it is possible that postponing cancer surgery without consideration of its implications could cost more lives than can be saved by diverting all surgical resources to COVID-19. This article provides general guidance on supporting curative surgical treatment where appropriate and with available resources.

PURPOSE: Tools to collect patient-reported outcome measures (PROMs) are frequently used in the healthcare setting to collect information that is most meaningful to patients. Due to discordance among how patients and healthcare providers rank symptoms that are considered most meaningful to the patient, engagement of patients in the development of PROMs is extremely important. This review aimed to identify studies that described how patients are involved in the item generation stage of cancer-specific PROM tools developed for cancer patients. METHODS: A literature search was conducted using keywords relevant to PROMs, cancer, and patient engagement. A manual search of relevant reference lists was also conducted. Inclusion criteria stipulated that publications must describe patient engagement in the item generation stage of development of cancer-specific PROM tools. Results were excluded if they were duplicate findings or non-English. RESULTS: The initial search yielded 230 publications. After removal of duplicates and review of publications, 6 were deemed relevant. Fourteen additional publications were retrieved through a manual search of references from relevant publications. A total of 13 unique PROM tools that included patient input in item generation were identified. The most common method of patient engagement was through qualitative interviews or focus groups. CONCLUSIONS: Despite recommendations from international groups and the emphasized importance of incorporating patient feedback in all stages of development of PROMs, few unique tools have incorporated patient input in item generation of cancer-specific tools. Moving forward, a framework of best practices on how to best engage patients in developing PROMs is warranted to support high-quality patient-centered care.

PURPOSE: Choosing Wisely Canada, modeled after Choosing Wisely in the United States, is intended to identify low-value or potentially harmful practices relevant to the Canadian health care environment. Our objective was to use multidisciplinary, pan-Canadian, physician-based consensus to identify a list of low-value or harmful cancer practices frequently used in Canada. METHODS: A Task Force convened by the Canadian Partnership Against Cancer included physician representation from the Canadian Society of Surgical Oncology, Canadian Association of Medical Oncologists, and Canadian Association of Radiation Oncology, and an expert advisor. The methodology included four phases: identify potentially relevant items, develop a long list, refine and reduce the long list to a short list, and select and endorse a final list. A framework-driven consensus process and a series of electronic surveys and voting processes were used to capture consensus. RESULTS: Sixty-six potentially relevant cancer-related practices were identified. The long list (41 practices) was reduced to a short list of 19 practices. Of the 10 practices on the final list, five are completely new, and five are revisions or adaptations of practices from previous US society lists. Six of the 10 involve multiple disease sites, and four are disease-site specific. One relates to diagnosis, six relate to treatment, two relate to surveillance/survivorship, and one practice spans the cancer care continuum. CONCLUSION: The cancer list was developed in partnership with the Canadian Society of Surgical Oncology, Canadian Association of Medical Oncologists, and Canadian Association of Radiation Oncology. Using knowledge translation and exchange efforts, this list should empower patients with cancer and physicians to assist in a targeted conversation about the appropriateness and quality of individual patient care.

Kisspeptin and its receptor, GPR54, are major regulators of the hypothalamic-pituitary-gonadal axis as well as regulators of human placentation and tumor metastases. GPR54 is a G(q/11)-coupled G protein-coupled receptor (GPCR), and activation by kisspeptin stimulates phosphatidy linositol 4, 5-biphosphate hydrolysis, Ca(2+) mobilization, arachidonic acid release, and ERK1/2 MAPK phosphorylation. Physiological evidence suggests that GPR54 undergoes agonist-dependent desensitization, but underlying molecular mechanisms are unknown. Furthermore, very little has been reported on the early events that regulate GPR54 signaling. The lack of information in these important areas led to this study. Here we report for the first time on the role of GPCR serine/threonine kinase (GRK)2 and beta-arrestin in regulating GPR54 signaling in human embryonic kidney (HEK) 293 cells, a model cell system for studying the molecular regulation of GPCRs, and genetically modified MDA MB-231 cells, an invasive breast cancer cell line expressing about 75% less beta-arrestin-2 than the control cell line. Our study reveals that in HEK 293 cells, GPR54 is expressed both at the plasma membrane and intracellularly and also that plasma membrane expression is regulated by cytoplasmic tail sequences. We also demonstrate that GPR54 exhibits constitutive activity, internalization, and association with GRK2 and beta- arrestins-1 and 2 through sequences in the second intracellular loop and cytoplasmic tail of the receptor. We also show that GRK2 stimulates the desensitization of GPR54 in HEK 293 cells and that beta-arrestin-2 mediates GPR54 activation of ERK1/2 in MDA-MB-231 cells. The significance of these findings in developing molecular-based therapies for treating certain endocrine-related disorders is discussed.
