Abstract
INTRODUCTION The aim of this systematic review was to summarize the current literature on wearable technologies in oncology patients for the purpose of prognostication, treatment monitoring, and rehabilitation planning. METHODS A search was conducted in Medline ALL, Cochrane Central Register of Controlled Trials, Embase, Emcare, CINAHL, Scopus, and Web of Science, up until February 2022. Articles were included if they reported on consumer grade and/or non-commercial wearable devices in the setting of either prognostication, treatment monitoring or rehabilitation. RESULTS We found 199 studies reporting on 18 513 patients suitable for inclusion. One hundred and eleven studies used wearable device data primarily for the purposes of rehabilitation, 68 for treatment monitoring, and 20 for prognostication. The most commonly-reported brands of wearable devices were ActiGraph (71 studies; 36%), Fitbit (37 studies; 19%), Garmin (13 studies; 7%), and ActivPAL (11 studies; 6%). Daily minutes of physical activity were measured in 121 studies (61%), and daily step counts were measured in 93 studies (47%). Adherence was reported in 86 studies, and ranged from 40% to 100%; of these, 63 (74%) reported adherence in excess of 80%. CONCLUSION Wearable devices may provide valuable data for the purposes of treatment monitoring, prognostication, and rehabilitation. Future studies should investigate live-time monitoring of collected data, which may facilitate directed interventions.

Abstract
BACKGROUND The intersection of race and older age compounds existing health disparities experienced by historically marginalised communities. Therefore, racialised older adults with cancer are more disadvantaged in their access to cancer clinical trials compared with age-matched counterparts. To determine what has already been published in this area, the rapid scoping review question are: what are the barriers, facilitators and potential solutions for enhancing access to cancer clinical trials among racialised older adults? METHODS We will use a rapid scoping review methodology in which we follow the six-step framework of Arksey and O'Malley, including a systematic search of the literature with abstract and full-text screening to be conducted by two independent reviewers, data abstraction by one reviewer and verification by a second reviewer using an Excel data abstraction sheet. Articles focusing on persons aged 18 and over who identify as a racialised person with cancer, that describe therapies/therapeutic interventions/prevention/outcomes related to barriers, facilitators and solutions to enhancing access to and equity in cancer clinical trials will be eligible for inclusion in this rapid scoping review. ETHICS AND DISSEMINATION All data will be extracted from published literature. Hence, ethical approval and patient informed consent are not required. The findings of the scoping review will be submitted for publication in a peer-reviewed journal and presentation at international conferences.

Abstract
OBJECTIVES There is limited guidance on how to effectively promote safety culture in health care settings. We performed a systematic review to identify interventions to promote safety culture, specifically in oncology settings. METHODS Medical Subject Headings and text words for "safety culture" and "cancer care" were combined to conduct structured searches of MEDLINE, EMBASE, CDSR, CINAHL, Cochrane CENTRAL, PsycINFO, Scopus, and Web of Science for peer-reviewed articles published from 1999 to 2021. To be included, articles had to evaluate a safety culture intervention in an oncology setting using a randomized or nonrandomized, pre-post (controlled or uncontrolled), interrupted time series, or repeated-measures study design. The review followed PRISMA guidelines; quality of included citations was assessed using the ROBINS-I risk of bias tool. RESULTS Eighteen articles meeting the inclusion criteria were retained, reporting on interventions in radiation (14 of 18), medical (3 of 18), or general oncology (1 of 18) settings. Articles most commonly addressed incident learning systems (7 of 18), lean initiatives (4 of 18), or quality improvement programs (3 of 18). Although 72% of studies reported improvement in safety culture, there was substantial heterogeneity in the evaluation approach; rates of reporting of adverse events (9 of 18) or Agency for Healthcare Research and Quality Safety Culture survey results (9 of 18) were the most commonly used metrics. Most of the studies had moderate (28%) or severe (67%) risk of bias. CONCLUSIONS Despite a growing evidence base describing interventions to promote safety culture in cancer care, definitive recommendations were difficult to make because of heterogeneity in study designs and outcomes. Implementation of incident learning systems seems to hold most promise.

Abstract
OBJECTIVE Low-grade serous ovarian cancer (LGSC) represents 5% of all epithelial ovarian cancers. They are characterized by indolent growth and KRAS and BRAF mutations, differing from high-grade serous ovarian cancer both clinically and molecularly. LGSC has low response rates to traditional systemic therapies, including chemotherapy and hormonal therapy. The objective of this systematic review was to appraise the literature describing the efficacy of MEK inhibitors in the treatment of LGSC. METHODS A comprehensive search was conducted of the following databases: Medline ALL, EMBASE, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Web of Sciences, ClinicalTrials.gov, International Clinical Trials Registry Platform (ICFRP), and International Standard Randomized Controlled Trials Number (ISRCTN) Registry. All studies investigating MEKi in the treatment of LGSC in the adjuvant or recurrent setting for patients 18 years of age or older were included. All titles/abstracts were then screened by 2 independent reviewers (A.K. and C.C.). The full-text articles were then screened. All disagreements were resolved by a third independent reviewer (T.Z.). Two independent reviewers (A.K. and C.C.) extracted data from the studies deemed eligible for final review. RESULTS A total of 2108 studies were identified in the initial search. Of these, a total of 4 studies met the eligibility criteria for systematic review. In these studies, 416 patients were treated with an MEKi alone. All patients included in the studies were being treated for LGSC in the recurrent setting. Varied results and efficacy of the MEKi were reported in each study. CONCLUSIONS The results highlighted in this systematic review demonstrate varied responses to MEKi for recurrent LGSC. Further research is needed in this field comparing the efficacy to current therapies, as well as to further evaluate the safety and toxicity profile with long-term use of MEKi.

Abstract
PURPOSE We undertook a scoping review of the literature to synthesize what is known about lymphoma survivorship and develop a comprehensive set of lymphoma-specific survivorship recommendations. METHODS We searched the peer-reviewed literature from January 1995 to April 2022, focused on topics relevant to survivorship care in patients ≥ 18 years of age, treated curatively for non-Hodgkin's and Hodgkin's lymphoma, and in remission for at least 2 years. RESULTS We retained 92 articles; themes included late effects of treatment (53.3%, 49/92), particularly fatigue and sleep disturbances, and fertility, as well as psychosocial considerations of survivors (27.2%; 25/92), screening for secondary malignancies (22.8%; 21/92), outcomes of interventions to improve survivorship care (10.9%; 10/92), and best practices and elements for survivorship plans (8.7%; 8/92). While there were published guidelines for screening for recurrence and secondary malignancies, despite the considerable number of articles on the psychosocial aspects of survivorship care, there remains limited guidance on screening frequency and management strategies for anxiety and depression, sleep disturbances, and treatment-related fatigue within the lymphoma population. CONCLUSION We have developed a comprehensive set of lymphoma-survivorship recommendations; however, work is needed to adapt them to local healthcare contexts. IMPLICATIONS FOR SURVIVORS While there is a focus in the literature on the long-term psychosocial impacts of cancer and its treatment on lymphoma survivors, there remains no concrete recommendations on effective screening and management of detriments to quality of life such as anxiety, depression, fatigue, and distress, and availability of local resources vary widely.

Abstract
With increasing reliance on technology in oncology, the impact of digital clinical decision support (CDS) tools needs to be examined. A systematic review update was conducted and peer-reviewed literature from 2016 to 2022 were included if CDS tools were used for live decision making and comparatively assessed quantitative outcomes. 3369 studies were screened and 19 were included in this updated review. Combined with a previous review of 24 studies, a total of 43 studies were analyzed. Improvements in outcomes were observed in 42 studies, and 34 of these were of statistical significance. Computerized physician order entry and clinical practice guideline systems comprise the greatest number of evaluated CDS tools (13 and 10 respectively), followed by those that utilize patient-reported outcomes (8), clinical pathway systems (8) and prescriber alerts for best-practice advisories (4). Our review indicates that CDS can improve guideline adherence, patient-centered care, and care delivery processes in oncology.

Abstract
INTRODUCTION A head and neck cancer (HNC) diagnosis significantly impacts a patient's quality of life (QOL). Palliative care potentially improves their QOL. We will conduct a scoping review to identify existing knowledge about palliative care interventions for patients with HNC. METHODS AND ANALYSIS This scoping review was designed in accordance with the JBI Manual for Evidence Synthesis: Scoping Reviews and will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. Our eligibility criteria follow the Population, Intervention, Comparison or Control, Outcomes and Study characteristics framework. The population is adult patients with locally advanced, metastatic, unresectable and/or recurrent HNC. We include peer-reviewed journal articles and articles in the press, in English, reporting on palliative care interventions with at least two of the eight National Consensus Project on Clinical Practice Guidelines for Quality Palliative Care domains; studies with and without comparators will be included. The outcomes are patient QOL (primary) and symptom severity, patients' satisfaction with care, patients' mood, advance care planning and place of death (secondary). We developed a search strategy across ten databases, to be searched from the inception to 11 September 2023: Medline ALL (Medline and EPub Ahead of Print and In-Process, In-Data-Review & Other Non-Indexed Citations), Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Embase Classic+Embase, Emcare and PsycINFO all from the OvidSP platform; CINAHL from EBSCOhost, Scopus from Elsevier, Web of Science from Clarivate and Global Index Medicus from WHO. We will extract data using a piloted data form and analyse the data through descriptive statistics and thematic analysis. ETHICS AND DISSEMINATION Ethics approval is not needed for a scoping review. We will disseminate the findings to healthcare providers and policy-makers by publishing the results in a scientific journal.

Abstract
Background The prognosis of hepatocellular carcinoma (HCC) is influenced by both tumor and patient specific factors. Current therapies of advanced HCC target angiogenesis and immune evasion, however there are no clinically useful biomarkers to guide clinicians. Methods Our aim in this retrospective cohort study was to validate single nucleotide polymorphisms (SNPs) prognostic of outcome in advanced HCC from the literature, and to analyze exploratory SNPs chosen from evaluation of the HCC tumor immune microenvironment. Using a database of patients with HCC treated with sorafenib, blood samples were genotyped, clinical variables were retrospectively collected, and SNPs were analyzed for association with progression-free survival (PFS) and overall survival (OS). A subsequent analysis was conducted to determine if identified SNPs were prognostic in trans arterial chemoembolization (TACE) treated patients. Results Literature review identified 7 SNPs in vascular endothelial growth factor (VEGF), eNOS, angiopoietin 2 (ANGPT2) and vascular endothelial growth factor receptor 2 (VEGFR2), however none were externally validated in our dataset. Of the 35 exploratory immunomodulatory SNPs, the following were associated with PFS or OS: CCL2 C-C motif ligand 2 (CCL2) (rs1024611), interleukin-10 (IL-10) (rs1800896), cytotoxic T-lymphocyte antigen-4 (CTLA-4) (rs231775) and NFKB1 (rs28362491). Conclusions SNPs identified by literature review to be prognostic in sorafenib treated patients with advanced HCC were not validated in our dataset. Our findings suggest potentially important prognostic implications of SNPs in VEGFR2, CCL2, IL-10, CTLA-4 and NFKB1 that deserve further study.

Abstract
PURPOSE/OBJECTIVE(S) Advances in image-guided brachytherapy have increased the interest in focal brachytherapy (F-BT) approaches to optimize disease control, while reducing the toxicities associated whole gland treatments for prostate cancer (PCa). In this study we performed a systematic review to report biochemical control (BC), and genitourinary (GU) and gastrointestinal (GI) toxicity rates in patients with localized prostate cancer treated with F-BT as a definitive or salvage modality. MATERIALS/METHODS This project was registered in the PROSPERO database (ID CRD42022320921). A comprehensive literature search was conducted in Cochrane Central databases, Cochrane Database of Systematic Reviews, Embase Classic +Embase, and Medline ALL, all from the OvidSP platform and Web of Science from Clarivate, from each database's inception to July 2022. Search was restricted to English and included terms: focal brachytherapy/prostate cancer, partial brachytherapy/prostate cancer. In total, 14862 articles were identified. Manuscripts that not related to focal or partial prostate brachytherapy, review papers and studies not reporting BC were excluded. After eliminating duplicates, and studies deemed irrelevant by consensus among three independent reviewers, 44 articles remained for in-depth review and data extraction. RESULTS Thirty studies that included BC outcomes were included for this analysis, comprising 1556 patients treated with F-BT for PCa. Of these, 1094 (70%) and 462 (30%) underwent F-BT as definitive monotherapy or salvage, respectively; while 585 (38%) and 971 (62%) received HDR or LDR, respectively. For F-BT as monotherapy, the most commonly prescribed dose for HDR was 19 Gy in 1 fraction (range 19-24 Gy), and for LDR, 145 Gy (90-160Gy). Whereas for salvage F-BT, most common dose schedule of HDR was 19Gy in 1 fraction (19-27GY) and LDR 145Gy (144-145Gy). BC random effects estimate for F-BT monotherapy at 1-, 2-, 3-, and 5-years were 100% (P = 1.0), 96% (P = 0.45), 91% (P = 0.45) and 87% (P< 0.01), respectively. Whereas BC random effects estimate for salvage at 1-, 2-, 3-, and 5-years were 91% (P = 0.86), 68% (0.17), and 57% (P = 0.20), respectively. GI and GU grade 3-4 crude toxicity rates for monotherapy and salvage ranged from 0-3.33% and 0-17%, respectively. CONCLUSION Over the last decade, there has been increasing interest in F-BT approaches, both as monotherapy and in the salvage setting. BC and toxicity profiles of F-BT appear favorable, and future studies directly comparing with whole-gland treatments are warranted.

Abstract
Serous epithelial ovarian cancer, classified as either high-grade (90%) or low-grade (10%), varies in molecular, histological, and clinicopathological presentation. Low-grade serous ovarian cancer (LGSOC) is a rare histologic subtype that lacks disease-specific evidence-based treatment regimens. However, LGSOC is relatively chemo-resistant and has a poor response to traditional treatments. Alternative treatments, including biologic therapies such as bevacizumab, have shown some activity in LGSOC. Thus, the objective of this systematic review is to determine the effect and safety of bevacizumab in the treatment of LGSOC. Following PRISMA guidelines, Medline ALL, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Embase all from the OvidSP platform, ClinicalTrials.gov, International Clinical Trials Registry Platform, International Standard Randomised Controlled Trial Number Registry were searched from inception to February 2022. Articles describing bevacizumab use in patients with LGSOC were included. Article screening, data extraction, and critical appraisal of included studies were completed by two independent reviewers. The effect of bevacizumab on the overall response rate, progression-free survival, overall survival, and adverse effects were summarized. The literature search identified 3064 articles, 6 of which were included in this study. A total of 153 patients were analyzed; the majority had stage IIIC cancer (56.2%). The overall median response rate reported in the studies was 47.5%. Overall, bevacizumab is a promising treatment for LGSOC, with response rates higher than traditional treatment modalities such as conventional chemotherapy, and is often overlooked as a treatment tool. A prospective clinical trial evaluating the use of bevacizumab in LGSOC is necessary to provide greater evidence and support these findings.

Abstract
INTRODUCTION Health numeracy (numerical literacy) refers to an individual's ability to use numerical information to make effective health decisions. Numeracy is fundamental in the role of a health care provider, forming the basis of evidence-based medicine and effective patient-provider communication. Despite a high level of education, many health care providers struggle with numeracy. Numeracy is often integrated into training curricula; however, teaching modality, competencies covered, learner satisfaction, and effectiveness of these educational interventions varies. METHOD A scoping review was conducted to explore and summarize what is known about numeracy skills education programs for health care providers. A comprehensive literature search was conducted from January 2010 to April 2021 in 10 databases. Controlled vocabulary terms and text words were used. The search was restricted to human studies, adults, and the English language. Articles were included if they were related to numeracy education for health care providers or trainees and provided details regarding methods, evaluation, and results. RESULTS The literature search retrieved 31,611 results and 71 met the inclusion criteria. Most interventions were conducted in a university setting, and targeted nursing students, medical students, resident physicians, and pharmacy students. Common numeracy concepts included statistics/biostatistics, medication calculations, evidence-based medicine, research methodology, and epidemiology. A variety of teaching modalities were used, which most often combined active approaches (eg, workshops, laboratories, small-group exercises, and discussion boards) with passive approaches (eg, traditional lectures and didactic teaching). Measured outcomes included knowledge and skills, self-efficacy, attitudes, and engagement. DISCUSSION Although efforts have been made to incorporate numeracy into training curricula, greater emphasis should be placed on developing strong numeracy skills in health care providers, particularly given the role numerical information plays in clinical decision making, evidence-based practices, and patient-provider communication.

Abstract
Introduction With the COVID-19 pandemic, most continuing medical education activities became virtual (VCME). The authors conducted a scoping review to synthesize the advantages and disadvantages of VCME to establish the impact of this approach on inequities that physicians face along the intersections of gender, race, and location of practice. Methods Guided by the methodological framework of Arksey and O'Malley, the search included six databases and was limited to studies published between January 1991 to April 2021. Eligible studies included those related to accredited/non-accredited post-certification medical education, conferences, or meetings in a virtual setting focused on physicians. Numeric and inductive thematic analyses were performed. Results 282 studies were included in the review. Salient advantages identified were convenience, favourable learning formats, collaboration opportunities, effectiveness at improving knowledge and clinical practices, and cost-effectiveness. Prominent disadvantages included technological barriers, poor design, cost, lack of sufficient technological skill, and time. Analysis of the studies showed that VCME was most common in the general/family practice specialty, in suburban settings, and held by countries in the Global North. A minority of studies reported on gender (35%) and race (4%). Discussion Most studies report advantages of VCME, but disadvantages and barriers exist that are contextual to the location of practice and medical subspecialty. VCME events are largely organized by Global North countries with suboptimized accessibility for Global South attendees. A lack of reported data on gender and race reveals a limited understanding of how VCME affects vulnerable populations, prompting potential future considerations as it evolves.

Abstract
PURPOSE Global increases in cancer, coupled with a shortage of cancer specialists, has led to an increasing role for primary care providers (PCP) in cancer care. This review aimed to examine all extant cancer curricula for PCPs and to analyze the motivations for curriculum development. METHODS A comprehensive literature search was conducted from inception to October 13, 2021, with no language restrictions. The initial search yielded 11,162 articles and 10,902 articles underwent title and abstract review. After full-text review, 139 articles were included. Numeric and thematic analyses were conducted and education programs were evaluated using Bloom's taxonomy. RESULTS Most curricula were developed in high-income countries (HICs), with 58% in the United States. Cancer-specific curricula focused on HIC priority cancers, such as skin/melanoma, and did not represent the global cancer burden. Most (80%) curricula were developed for staff physicians and 73% focused on cancer screening. More than half (57%) of programs were delivered in person, with a shift toward online delivery over time. Less than half (46%) of programs were codeveloped with PCPs and 34% did not involve PCPs in the program design and development. Curricula were primarily developed to improve cancer knowledge, and 72 studies assessed multiple outcome measures. No studies included the top two levels of Bloom's taxonomy of learning (evaluating; creating). CONCLUSION To our knowledge, this is the first review to assess the current state of cancer curricula for PCPs with a global focus. This review shows that extant curricula are primarily developed in HICs, do not represent the global cancer burden, and focus on cancer screening. This review lays a foundation to advance the cocreation of curricula that are aligned to the global cancer burden.

Abstract
BACKGROUND Electronic prospective surveillance models (ePSMs) for cancer rehabilitation include routine monitoring of the development of treatment toxicities and impairments via electronic patient-reported outcomes. Implementing ePSMs to address the knowledge-to-practice gap between the high incidence of impairments and low uptake of rehabilitation services is a top priority in cancer care. METHODS We conducted a scoping review to understand the state of the evidence concerning the implementation of ePSMs in oncology. Seven electronic databases were searched from inception to February 2021. All articles were screened and extracted by two independent reviewers. Data regarding the implementation strategies, outcomes, and determinants were extracted. The Expert Recommendations for Implementing Change taxonomy and the implementation outcomes taxonomy guided the synthesis of the implementation strategies and outcomes, respectively. The Consolidated Framework for Implementation Research guided the synthesis of determinants based on five domains (intervention characteristics, individual characteristics, inner setting, outer setting, and process). RESULTS Of the 5122 records identified, 46 interventions met inclusion criteria. The common implementation strategies employed were "conduct educational meetings," "distribute educational materials," "change record systems," and "intervene with patients to enhance uptake and adherence." Feasibility and acceptability were the prominent outcomes used to assess implementation. The complexity, relative advantage, design quality, and packaging were major implementation determinants at the intervention level. Knowledge was key at the individual level. At the inner setting level, major determinants were the implementation climate and readiness for implementation. At the outer setting level, meeting the needs of patients was the primary determinant. Engaging various stakeholders was key at the process level. CONCLUSIONS This review provides a comprehensive summary of what is known concerning the implementation of ePSMs. The results can inform future implementation and evaluation of ePSMs, including planning for key determinants, selecting implementation strategies, and considering outcomes alongside local contextual factors to guide the implementation process.

Abstract
Objective Medical care for cancer is increasingly directed by genomic laboratory testing for alterations in the tumor genome that are significant for diagnosis, prognosis and therapy. Uniquely in medicine, providers must search the biomedical literature for each patient to determine the clinical significance of these alterations. Access to published scientific literature is frequently subject to high fees, with access limited to institutional subscriptions. We sought to investigate the degree to which the scientific literature is accessible to clinical cancer genomics providers, and the potential role of university and hospital system libraries in information access for cancer care. Methods We identified 265 journals that were accessed during the interpretation and reporting of clinical test results from 1,842 cancer patients at the University Health Network (Toronto, Canada). We determined the degree of open access for this set of clinically important literature, and for any journals not available through open access we surveyed subscription access at seven academic hospital systems and at their affiliated universities. Results This study found that nearly half (116/265) of journals have open access mandates that make articles freely available within one year of release. For the remaining subscription access journals, universities provided a uniformly high level of access, but access available through hospital system collections varied widely. Conclusion This study highlights the importance of different modes of access to the use of the scientific literature in clinical practice and points to challenges that must be overcome as genomic medicine grows in scale and complexity.

Abstract
This scoping review explored what is known about the experiences of informal cancer caregivers (CGs) who are newcomers with limited language proficiency. A literature search was performed in seven databases and the search yielded 11,289 articles. After duplicate removal and title and abstract screening, 216 articles underwent full text review and 57 articles and were synthesized. Most studies (n = 41, 72%) were qualitative and were published in North America (n = 35, 61%). Most CG participants were female (69%) and only 19 studies explicitly identified the CG country of origin. Of those that did, 26% originated from Asia, with most migrating from East Asia. Significant challenges were experienced by newcomer CGs and chief among these were related to communication challenges with HCPs that were exacerbated by a lack of availability of medical interpreters and the complexity of oncology health information. Efforts are needed to better integrate newcomer CGs into cancer care.

Abstract
Background The best supplemental breast cancer screening modality in women at average risk or intermediate risk for breast cancer with dense breast and negative mammogram remains to be determined. Purpose To conduct systematic review and meta-analysis comparing clinical outcomes of the most common available supplemental screening modalities in women at average risk or intermediate risk for breast cancer in patients with dense breasts and mammography with negative findings. Materials and Methods A comprehensive search was conducted until March 12, 2020, in Medline, Epub Ahead of Print and In-Process and Other Non-Indexed Citations; Embase Classic and Embase; Cochrane Central Register of Controlled Trials; and Cochrane Database of Systematic Reviews, for Randomized Controlled Trials and Prospective Observational Studies. Incremental cancer detection rate (CDR); positive predictive value of recall (PPV1); positive predictive value of biopsies performed (PPV3); and interval CDRs of supplemental imaging modalities, digital breast tomosynthesis, handheld US, automated breast US, and MRI in non-high-risk patients with dense breasts and mammography negative for cancer were reviewed. Data metrics and risk of bias were assessed. Random-effects meta-analysis and two-sided metaregression analyses comparing each imaging modality metrics were performed (PROSPERO; CRD42018080402). Results Twenty-two studies reporting 261 233 screened patients were included. Of 132 166 screened patients with dense breast and mammography negative for cancer who met inclusion criteria, a total of 541 cancers missed at mammography were detected with these supplemental modalities. Metaregression models showed that MRI was superior to other supplemental modalities in CDR (incremental CDR, 1.52 per 1000 screenings; 95% CI: 0.74, 2.33; P < .001), including invasive CDR (invasive CDR, 1.31 per 1000 screenings; 95% CI: 0.57, 2.06; P < .001), and in situ disease (rate of ductal carcinoma in situ, 1.91 per 1000 screenings; 95% CI: 0.10, 3.72; P < .04). No differences in PPV1 and PPV3 were identified. The limited number of studies prevented assessment of interval cancer metrics. Excluding MRI, no statistically significant difference in any metrics were identified among the remaining imaging modalities. Conclusion The pooled data showed that MRI was the best supplemental imaging modality in women at average risk or intermediate risk for breast cancer with dense breasts and mammography negative for cancer. © RSNA, 2023 Supplemental material is available for this article.

Abstract
INTRODUCTION Antimicrobial resistance (AMR) is a growing global public health concern and is becoming a significant challenge in the management of patients with cancer. Due to the immunosuppressive nature of cancer treatment, infection is a common complication and the necessary high usage of antibiotics increases the risk of AMR. Failure to adequately prevent and treat infection in patients with cancer as a result of AMR can increase the morbidity and mortality of the disease. The objective of this scoping review is to understand the relationship between AMR and cancer in order to develop effective antimicrobial stewardship in this patient population and minimise the detrimental effects of AMR on cancer outcomes. METHODS AND ANALYSIS This scoping review will follow the Arksey and O'Malley methodology framework. An exploratory review of the literature on antibiotic resistance in cancer care will help to define the research questions (stage 1). A broad range of electronic databases (MEDLINE ALL, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews and Embase) and search terms will be used to retrieve relevant articles published between 2000 and 2021 (stage 2). Studies will be systematically selected based on the eligibility criteria by two independent reviewers (stage 3). The titles and abstracts will be appraised to determine whether articles meet the eligibility criteria. This will be followed by screening of the full texts and only relevant publications will be retrieved. Data will then be extracted, collated and charted (stage 4); and the summary of aggregated results will be presented (stage 5). ETHICS AND DISSEMINATION As this scoping review will collect and synthesise data from publicly available sources, no ethics review is required. When data collection and summarisation is completed, results will be disseminated through peer-reviewed publication and the key findings of the review will be presented at relevant conferences.

Abstract
Populations with limited language proficiency (LLP) experience difficulties understanding health information and accessing care. This study aimed to explore health literacy and LLP by examining the published literature on the barriers and facilitators to health care. METHODS A scoping review of studies with populations in countries and regions where they have LLP in the locally dominant language was conducted. RESULTS One-hundred and forty-three (143) articles met eligibility criteria. Most studies were conducted in North America (n = 99, 69.2%) and the primary language of study participants was Spanish (n = 32; 22.4%). Limited language proficiency was associated with low health literacy. Age was a consistent predictor of LLP, while education was predictive of low health literacy. Low health literacy was associated with poorer health outcomes. DISCUSSION This review synthesizes the existing research regarding populations with LLP and their health literacy, demonstrating the importance that the intersection between the two has on patient experiences and behaviors.

Abstract
BACKGROUND Age-related complex medical conditions have been commonly reported among adolescents and young adults with advanced life-limiting illness. There is increasing interest in exploring their palliative care needs and end-of-life experiences. AIM This scoping review aimed to explore the available literature about providing palliative and end-of-life care to adolescents and young adults with advanced life-limiting illnesses. DESIGN Scoping review. This review was registered on Open Science Framework (https://doi.org/10.17605/OSF.IO/SPTD7). DATA SOURCES Electronic databases (MEDLINEALL, Embase, Emcare, Cochrane Central Register of Controlled Trial CENTRAL, Scopus, PsycINFO, Cochrane Database of Systematic Reviews), Google Scholar and reference lists were searched up to October 2021. We included studies reporting on adolescents and/or young adults with advanced life-limiting illnesses. There were no limitations concerning location, type of illness or study design. RESULTS We identified 51 studies published between 2002 and 2021. Most studies were published in the United States (n = 34, 67%), and nine studies (18%) reported exclusively on patients with non-malignant illnesses. Two thirds of the identified studies were case reports and retrospective chart reviews (n = 33). Three main topics were identified: Physical symptom burden (n = 26, 51%), Psychological and social needs (n = 33, 65%), and end-of-life care (n = 30, 59%). Twenty-six studies (51%) were focused only on one topic, and the age range used to identify adolescents and young adults varied based on the study location. CONCLUSION The findings of this review shed light on the different palliative care experiences and knowledge gaps related to adolescents and young adults as an underserved and vulnerable patient population. Further research needs to be dedicated toward palliative care programs tailored for adolescents and young adults.

Abstract
BACKGROUND People who use drugs with life-limiting illnesses experience substantial barriers to accessing palliative care. Demand for palliative care is expected to increase during communicable disease epidemics and pandemics. Understanding how epidemics and pandemics affect palliative care for people who use drugs is important from a service delivery perspective and for reducing population health inequities. AIM To explore what is known about communicable disease epidemics and pandemics, palliative care, and people who use drugs. DESIGN Scoping review. DATA SOURCES We searched six bibliographic databases from inception to April 2021 as well as the grey literature. We included English and French records about palliative care access, programs, and policies and guidelines for people ⩾18 years old who use drugs during communicable disease epidemics and pandemics. RESULTS Forty-four articles were included in our analysis. We identified limited knowledge about palliative care for people who use drugs during epidemics and pandemics other than HIV/AIDS. Through our thematic synthesis of the records, we generated the following themes: enablers and barriers to access, organizational barriers, structural inequity, access to opioids and other psychoactive substances, and stigma. CONCLUSIONS Our findings underscore the need for further research about how best to provide palliative care for people who use drugs during epidemics and pandemics. We suggest four ways that health systems can be better prepared to help alleviate the structural barriers that limit access as well as support the provision of high-quality palliative care during future epidemics and pandemics.

Abstract
BACKGROUND Continued smoking after a diagnosis of cancer negatively impacts cancer outcomes, but the impact of tobacco on newer treatments options is not well established. Collecting and evaluating tobacco use in clinical trials may advance understanding of the consequences of tobacco use on treatment modalities, but little is known about the frequency of reporting and analysis of tobacco use in cancer cooperative clinical trial groups. PATIENTS AND METHODS A comprehensive literature search was conducted to identify cancer cooperative group clinical trials published from January 2017-October 2019. Eligible studies evaluated either systemic and/or radiation therapies, included ≥100 adult patients, and reported on at least one of: overall survival, disease/progression-free survival, response rates, toxicities/adverse events, or quality-of-life. RESULTS A total of 91 studies representing 90 trials met inclusion criteria with trial start dates ranging from 1995 to 2015 with 14% involving lung and 5% head and neck cancer patients. A total of 19 studies reported baseline tobacco use; 2 reported collecting follow-up tobacco use. Seven studies reported analysis of the impact of baseline tobacco use on clinical outcomes. There was significant heterogeneity in the reporting of baseline tobacco use: 7 reported never/ever status, 10 reported never/ex-smoker/current smoker status, and 4 reported measuring smoking intensity. None reported verifying smoking status or second-hand smoke exposure. Trials of lung and head and neck cancers were more likely to report baseline tobacco use than other disease sites (83% versus 6%, P < 0.001). CONCLUSIONS Few cancer cooperative group clinical trials report and analyze trial participants' tobacco use. Significant heterogeneity exists in reporting tobacco use. Routine standardized collection and reporting of tobacco use at baseline and follow-up in clinical trials should be implemented to enable investigators to evaluate the impact of tobacco use on new cancer therapies.

Abstract
IMPORTANCE Epidemiological evidence supports a role for statins in improving survival in advanced prostate cancer, particularly among men receiving androgen-ablative therapies. OBJECTIVE To study the association between statin use and survival among men with prostate cancer receiving androgen deprivation therapy (ADT) or androgen receptor axis-targeted therapies (ARATs). DATA SOURCES This systemic review and meta-analysis used sources from MEDLINE, EMBASE, Epub Ahead of Print, Cochrane Clinical Trials, Cochrane Systematic Reviews, and Web of Science from inception to September 6, 2022. STUDY SELECTION Observational studies reporting associations of concurrent statin use and survival outcomes (in hazard ratios [HRs]). DATA EXTRACTION AND SYNTHESIS Two authors independently abstracted all data. Summary estimates pooled multivariable HRs with 95% CIs using the generic inverse variance method with random-effects modeling. A priori specified subgroup and sensitivity analyses were undertaken, and heterogeneity, study quality, and publication bias were evaluated. Confidence in the evidence was assessed using the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) approach. MAIN OUTCOMES AND MEASURES Overall mortality and prostate cancer-specific mortality (PCSM). RESULTS Twenty-five cohorts of 119 878 men (65 488 statin users [55%]) with more than 74 416 deaths were included. Concurrent statin use was associated with a 27% reduction in the risk of overall mortality (HR, 0.73 [95% CI, 0.66-0.82]; I2 = 83%) and a 35% reduction in the risk of PCSM (HR, 0.65 [95% CI, 0.58-0.73]; I2 = 74%), with substantial heterogeneity in both estimates. Subgroup analyses identified a PCSM advantage associated with statins for men receiving ARATs compared with ADT alone (HR, 0.40 [95% CI, 0.30-0.55] vs 0.68 [95% CI, 0.60-0.76]; P = .002 for difference). Confidence in the evidence was rated low for both outcomes. CONCLUSIONS AND RELEVANCE The findings of this meta-analysis show that concurrent statin use was associated with reduced overall mortality and PCSM among men receiving androgen-ablative therapies for advanced prostate cancer. These findings are limited by the observational nature of the data and residual unexplained interstudy heterogeneity. Randomized clinical trials are warranted to validate these results.

Abstract
The Choosing Wisely (CW) campaign, launched in 2012, includes oncology-specific recommendations to promote evidence-based care and deimplementation of low-value practices. However, it is unclear to what extent the campaign has prompted practice change. We systematically reviewed the literature to evaluate the uptake of cancer-specific CW recommendations focusing on the period before the declaration of the COVID-19 pandemic. We used Grimshaw's deimplementation framework to thematically group the findings and extracted information on implementation strategies, barriers, and facilitators from articles reporting on active implementation. In the 98 articles addressing 32 unique recommendations, most reported on passive changes in adherence pre-post publication of CW recommendations. Use of active surveillance for low-risk prostate cancer and reduction in staging imaging for early breast cancer were the most commonly evaluated recommendations. Most articles assessing passive changes in adherence pre-post CW publication reported improvement. All articles evaluating active implementation (10 of 98) reported improved compliance (range: 3%-73% improvement). Most common implementation strategies included provider education and/or stakeholder engagement. Preconceived views and reluctance to adopt new practices were common barriers; common facilitators included the use of technology and provider education to increase provider buy-in. Given the limited uptake of oncology-specific CW recommendations thus far, more attention toward supporting active implementation is needed. Effective adoption of CW likely requires a multipronged approach that includes building stakeholder buy-in through engagement and education, using technology-enabled forced functions to facilitate change along with policy and reimbursement models that disincentivize low-value care. Professional societies have a role to play in supporting this next phase of CW.

Abstract
PURPOSE Non-V600 mutations comprise approximately 35% of all BRAF mutations in cancer. Many of these mutations have been identified as oncogenic drivers and can be classified into three classes according to molecular characteristics. Consensus treatment strategies for class 2 and 3 BRAF mutations have not yet been established. METHODS We performed a systematic review and meta-analysis with published reports of individual patients with cancer harboring class 2 or 3 BRAF mutations from 2010 to 2021, to assess treatment outcomes with US Food and Drug Administration-approved mitogen-activated protein kinase (MAPK) pathway targeted therapy (MAPK TT) according to BRAF class, cancer type, and MAPK TT type. Coprimary outcomes were response rate and progression-free survival. RESULTS A total of 18,167 studies were screened, identifying 80 studies with 238 patients who met inclusion criteria. This included 167 patients with class 2 and 71 patients with class 3 BRAF mutations. Overall, 77 patients achieved a treatment response. In both univariate and multivariable analyses, response rate and progression-free survival were higher among patients with class 2 compared with class 3 mutations, findings that remain when analyses are restricted to patients with melanoma or lung primary cancers. MEK ± BRAF inhibitors demonstrated greater clinical activity in class 2 compared with class 3 BRAF-mutant tumors than BRAF or EGFR inhibitors. CONCLUSION This meta-analysis suggests that MAPK TTs have clinical activity in some class 2 and 3 BRAF-mutant cancers. BRAF class may dictate responsiveness to current and emerging treatment strategies, particularly in melanoma and lung cancers. Together, this analysis provides clinical validation of predictions made on the basis of a mutation classification system established in the preclinical literature. Further evaluation with prospective clinical trials is needed for this population.

Abstract
The risk of recurrence after discontinuation of anticoagulation for a combined oral contraceptive (COC)-associated venous thromboembolism (VTE) is unclear. Therefore, we conducted a systematic review and meta-analysis to estimate the incidence of recurrent VTE among women with COC-associated VTE, unprovoked VTE and to compare the incidence of recurrent VTE between the two groups. The Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Embase Classic +Embase and Medline ALL to July 2020 and citations from included studies were searched. Randomized controlled trials, prospective cohort studies and meta-analyses of these study types were selected. The analysis was conducted by random-effects model. Nineteen studies were identified including 1537 women [5828 person-years (PY)] with COC-associated VTE and 1974 women (7798 PY) with unprovoked VTE. Studies were at low risk of bias. The incidence rate of VTE recurrence was 1.22/100 PY [95% confidence interval (CI) 0.92-1.62, I2 = 6%] in women with COC-associated VTE, 3.89/100 PY (95% CI 2.93-5.17, I2 = 74%) in women with unprovoked VTE and the unadjusted incidence rate ratio was 0.34 (95% CI 0.26-0.46, I2 = 3%). The recurrence risk in women after COC-associated VTE is low and lower than after an unprovoked VTE.

Abstract
PURPOSE To provide evidence-based recommendations on the management of malignant bowel obstruction (MBO) for patients with advanced cancer. METHODS The Multinational Association for Supportive Care in Cancer (MASCC) MBO study group conducted a systematic review of databases (inception to March 2021) to identify studies about patients with advanced cancer and MBO that reported on the following outcomes: symptom management, bowel obstruction resolution, prognosis, overall survival, and quality of life. The review was restricted to studies published in English, but no restrictions were placed on publication year, country, and study type. As per the MASCC Guidelines Policy, the findings were synthesized to determine the levels of evidence to support each MBO intervention and, ultimately, the graded recommendations and suggestions. RESULTS The systematic review identified 17,656 published studies and 397 selected for the guidelines. The MASCC study group developed a total of 25 evidence-based suggestions and recommendations about the management of MBO-related nausea and vomiting, bowel movements, pain, inflammation, bowel decompression, and nutrition. Expert consensus-based guidance about advanced care planning and psychosocial support is also provided. CONCLUSION This MASCC Guideline provides comprehensive, evidence-based recommendations about MBO management for patients with advanced cancer.

Abstract
PURPOSE Current guidelines recommend somatic genomic sequencing for patients with advanced pancreatic cancer to identify targetable alterations amenable to targeted therapy. The benefit of somatic genomic sequencing in pancreatic cancer remains unclear. This study aims to assess the evidence supporting genomic sequencing to inform treatment selection for patients with advanced pancreatic cancer. METHODS A systematic review identified prospective studies of exocrine pancreatic cancer patients published before August 2020 which conducted genomic sequencing to inform treatment selection. Outcomes of interest included the proportion of patients with targetable alterations, the proportion that received targeted treatments, and the impact of targeted treatments on overall survival. Meta-analysis for proportions and hazard ratios was performed using Dersimonian and Laird random effect models. RESULTS 19 studies (representing 2048 pancreatic cancer patients) were included. Sequencing methodologies, definitions of targetable alterations, and approaches treatment selection varied across studies and were incompletely reported. 590 of 1382 sequenced patients harboured a targetable alteration (random effects meta-analysis estimate of the proportion 0.46, 95% confidence interval 0.32-0.61). The proportion of patients with targetable alterations was highly heterogenous between studies (I2 93%, P < 0.001). 91 of 1390 patients received a matched therapy based on their targetable alterations (random effects meta-analysis estimate of the proportion 0.12, 95% CI 0.06-0.23). One observational study reported an overall survival benefit of matched therapy. CONCLUSIONS Genomic sequencing frequently identifies targetable alterations in pancreatic cancers. Further research is required to standardize the definitions of targetable alterations, the approach to treatment matching, and quantify the benefit of targeted therapy.

Abstract
INTRODUCTION Communicable disease epidemics and pandemics magnify the health inequities experienced by marginalised populations. People who use substances suffer from high rates of morbidity and mortality and should be a priority to receive palliative care, yet they encounter many barriers to palliative care access. Given the pre-existing inequities to palliative care access for people with life-limiting illnesses who use substances, it is important to understand the impact of communicable disease epidemics and pandemics such as COVID-19 on this population. METHODS AND ANALYSIS We will conduct a scoping review and report according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews reporting guidelines. We conducted a comprehensive literature search in seven bibliographical databases from the inception of each database to August 2020. We also performed a grey literature search to identify the publications not indexed in the bibliographical databases. All the searches will be rerun in April 2021 to retrieve recently published information because the COVID-19 pandemic is ongoing at the time of this writing. We will extract the quantitative data using a standardised data extraction form and summarise it using descriptive statistics. Additionally, we will conduct thematic qualitative analyses and present our findings as narrative summaries. ETHICS AND DISSEMINATION Ethics approval is not required for a scoping review. We will disseminate our findings to healthcare providers and policymakers through professional networks, digital communications through social media platforms, conference presentations and publication in a scientific journal.

Abstract
OBJECTIVES Low-grade serous ovarian cancer (LGSC) is a relatively chemo-resistant disease with limited effective treatment options for patients with recurrence. Secondary cytoreductive surgery (SCS) is commonly offered at recurrence, although any benefit this has on survival is not fully determined. This review evaluates the impact of SCS, including residual disease, on progression-free survival (PFS) and overall survival (OS) in recurrent LGSC. METHODS A comprehensive search of Medline ALL, Embase Classic + Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Web of Science was conducted to obtain studies evaluating optimal or complete SCS versus suboptimal SCS and the amount of residual disease in recurrent LGSC. Meta-analysis was performed and PFS and OS outcomes were calculated. RESULTS 1Of 5296 studies screened, 350 progressed to full-text review, with 9 ultimately selected for inclusion in the systematic review. Two studies met criteria for meta-analysis of PFS and of OS. The presence of visible residual disease at the conclusion of SCS negatively impacted PFS (HR = 3.51, 95% CI = 1.72-7.14), whereas SCS with no residual disease significantly improved OS (HR = 0.4, 95% CI = 0.23-0.7) in patients with recurrent LGSC. Diffuse and extensive disease distribution was inversely linked to survival. In addition, SCS as an initial treatment for recurrent LGSC was associated with superior survival in comparison to chemotherapy. A short platinum-free interval was not associated with worse survival in this cohort. CONCLUSIONS Complete SCS, and to a lesser extent optimal SCS, are associated with improved PFS and OS in patients with recurrent LGSC. SCS may be a better initial treatment strategy than systemic chemotherapy for recurrent disease. Patients with recurrent LGSC should be evaluated for the role of SCS based on disease distribution and functional status, irrespective of the platinum-free interval. Prospective studies are needed to further study the role of SCS in patients with recurrent LGSC.

Abstract
Phase 1 dose-escalation trials are crucial to drug development by providing a framework to assess the toxicity of novel agents in a stepwise and monitored fashion. Despite widely adopted, rule-based dose-escalation methods (such as 3 + 3) are limited in finding the maximum tolerated dose (MTD) and tend to treat a significant number of patients at subtherapeutic doses. Newer methods of dose escalation, such as model-based and model-assisted designs, have emerged and are more accurate in finding MTD. However, these designs have not yet been broadly embraced by investigators. In this review, we summarise the advantages and disadvantages of contemporary dose-escalation methods, with emphasis on model-assisted designs, including time-to-event designs and hybrid methods involving optimal biological dose (OBD). The methods reviewed include mTPI, keyboard, BOIN, and their variations. In addition, the challenges of drug development (and dose-escalation) in the era of immunotherapeutics are discussed, where many of these agents typically have a wide therapeutic window. Fictional examples of how the dose-escalation method chosen can alter the outcomes of a phase 1 study are described, including the number of patients enrolled, the trial's timeframe, and the dose level chosen as MTD. Finally, the recent trends in dose-escalation methods applied in phase 1 trials in the immunotherapeutics era are reviewed. Among 856 phase I trials from 2014 to 2019, a trend towards the increased use of model-based and model-assisted designs over time (OR = 1.24) was detected. However, only 8% of the studies used non-rule-based dose-escalation methods. Increasing familiarity with such dose-escalation methods will likely facilitate their uptake in clinical trials.

Abstract
21 Background: The Choosing Wisely (CW) campaign launched in 2012 includes oncology-related recommendations (CWR) aimed at promoting evidence-based care and de-implementing low value practices; however, it remains unclear to what extent practice has changed as a result of the campaign. We undertook a scoping review to evaluate the extent of CWR uptake in oncology, and barriers and facilitators to implementation. Methods: A systematic search of MEDLINE, EMBASE, Cochrane, Emcare Nursing and Scopus was conducted for articles published between 2012 and March 6, 2020 pertaining to cancer-specific CWR. Articles were excluded if they did not report on cancer-specific recommendations, were commentaries/opinions, reported on screening or prevention, focused on pediatric populations, or were not in English. Retained articles were thematically grouped based on study objective. Implementation strategies, barriers and facilitators were summarized for articles implementing a recommendation into practice. Results: The search yielded 8565 articles; 98 articles were retained, addressing 32 unique recommendations. Use of active surveillance for low-risk prostate cancer (14/98) and reduction of imaging in early breast cancer (13/98) were the most commonly evaluated CWR. Of the 29 articles reporting on pre-post CW campaign adherence, 20 reported improved compliance without further intervention. In articles evaluating factors associated with CWR-concordance (62/98), age (23/62), stage or risk (22/62), and geographic location (21/62) most commonly influenced care decisions. Few articles described the development of interventions to improve concordance (1/98) or a protocol to evaluate implementation (2/98) with no further testing of their design. Of the 10/98 articles that evaluated implementation of a CWR, all reported improved compliance (range: 3-73% improvement). Implementation strategies were used in combination and most often included provider education (8/10), stakeholder engagement (6/10), and forced function (4/10). Preconceived views and reluctance to adopt new practices were the most commonly reported barriers to implementation; the use of technology to update practice and the use of education and evidence to build provider buy-in were the most common facilitators. Conclusions: In the eight years since the initial publication of oncology-specific CW recommendations, uptake has been limited. Publication of the recommendations has resulted in some passive improvements in care. Further adoption of CWR likely requires an implementation strategy that includes building stakeholder buy-in, and utilization of updated order sets and forced functions in technology to facilitate change. Future studies should assess the impact of the COVID-19 pandemic on the adoption of CWR and the de-implementation of low-value care.

Abstract
40 Background: Continued smoking after a diagnosis of cancer negatively impacts cancer outcomes but the impact of tobacco on many innovative treatments has not yet been well established. Collecting and evaluating tobacco use in cancer clinical trials may advance understanding of the consequences of tobacco use on specific treatment modalities. We performed a systematic scoping review of the frequency of reporting and analysis of tobacco use in clinical trials run by cancer cooperative clinical trial groups. Methods: A comprehensive literature search was conducted to identify cancer cooperative group clinical trials published from January 2017 to October 2019 using Medline, Epub Ahead of Print and In-Process & Other Non-Indexed Citations, Embase, Cochrane Central Register of Controlled Trials using OvidSP. Eligible studies evaluated either systemic and/or radiation therapies, involved at least one cancer cooperative group, included > 100 adult patients and reported on at least one primary or secondary endpoint, which included overall survival (OS), disease/progression-free survival (DFS/PFS), response rates, toxicities/adverse events, or quality of life (QoL). Secondary analyses of previously published trials were excluded. Results: Among 14843 identified studies, 91 studies representing 90 trials met inclusion criteria. 24% were phase II trials, 2% phase II/III and 74% phase III. Trial start dates ranged from 1995-2015 with most (29%) between 2007-2008; median trial sample size was 406 (range: 100-4994); 86% involved systematic therapy, 35% involved radiation; 14% were lung and 5% were head and neck trials. 51% of trials had a curative intent, 33% were palliative and 16% involved hematologic cancers. 74 studies reported on OS, 73 DFS/PFS, and 88 toxicity/QoL. 19 studies reported baseline tobacco use information, while two reported collecting follow-up tobacco use. Of those collecting baseline tobacco use, only 7 reported any analysis of the impact of tobacco on clinical outcomes. There was significant heterogeneity in the reporting of baseline tobacco use: 5 reported never/ever status, 10 reported never/ex-smoker/current smoker status; 4 reported some measure of smoking intensity; none reported on verifying smoking status or second hand smoke exposure. Trials of tobacco related (lung and head and neck) cancers were more likely to report baseline tobacco use compared to non-tobacco related cancers (83% vs 6% p < 0.001). Conclusions: Few cancer cooperative group clinical trials report and analyze trial participants’ baseline tobacco use, and even fewer collect follow up information. Significant heterogeneity exists in reporting tobacco use. Routine standardized collection and reporting of tobacco use, both at baseline and follow up in clinical trials, should be implemented to enable investigators to evaluate the clinical impact of tobacco use on new cancer therapies.

Abstract
PURPOSE The addition of platinum agents to anthracycline and taxane-based chemotherapy in early-stage triple negative breast cancer (TNBC) patients improves pathological complete response (pCR). Long-term outcomes, such as disease-free survival (DFS) and overall survival (OS), have not been well-established. METHODS A systematic literature review identified studies using platinum-based treatment in TNBC patients in the neoadjuvant or adjuvant setting with reportable long-term outcomes. Hazard ratios (HR) from collected data were pooled in a meta-analysis using generic inverse-variance and random effects modeling. Subgroup analyses were conducted based on treatment setting and study design. RESULTS Fourteen studies comprising 3518 patients met the inclusion criteria. Median follow up was 56.2 months. All studies reported DFS and 9 studies (64%) reported OS. DFS was significantly better in platinum-based treatment (HR 0.71, 95% confidence interval (CI) 0.56-0.89; p = 0.03). However, OS was no different (HR 0.98, 95% CI 0.75-1.27; p = 0.87). There was a non-significant difference between platinum exposure in the adjuvant compared to neoadjuvant setting for both DFS (HR 0.75 vs 0.62, p = 0.43) and for OS (HR 0.90 vs 1.10, p = 0.58). The addition of platinum was associated with more thrombocytopenia and all-grade neuropathy and non-significant increases in neutropenia and grade 3-4 neuropathy. CONCLUSIONS Platinum-based treatment improves DFS but not OS. The reporting of toxicity was suboptimal, but in general adding platinum increased toxicity. The discordant effect of platinum-based treatment on DFS and OS suggest the potential development of platinum resistance and worse outcomes after recurrence. Platinum-based chemotherapy cannot be recommended in unselected patients with early TNBC.

Abstract
OBJECTIVES In response to the COVID-19 pandemic there have been significant developments in research, its conduct and the supporting ethical framework. While many protocols have been delayed, halted or modified, other research efforts have been accelerated, generating controversy. The goal of this paper is to determine the rates of references surrounding the ethical oversight of research as reported in current COVID-19-related research publications. DESIGN Scoping review. SETTING Population-based observational or interventional studies from December 2019 to May 2020 with sample size of two or more. Studies were searched through electronic databases including Medline, EMBASE, and Cochrane CENTRAL Register of Controlled Trials. PARTICIPANTS Eligibility criteria included participants within published studies who tested positive for COVID-19. MAIN OUTCOMES AND MEASURES Data were extracted and charting methods included taking note of references to ethical frameworks, institutional review board (IRB), ethics committee (EC) or research ethics board (REB) involvement, consent processes, and other variables. RESULTS 11 556 articles were screened, with 656 included in the final analysis. References to ethics were present in 530 (80.8%) studies, with 491 (74.8%) involving IRB/ECs/REBs and 126 (19.2%) not referencing ethics. Consent processes were outlined in 201 (30.6%) studies, with 198 (30.2%) reporting that they obtained consent waivers, however, 257 (39.2%) did not mention consent at all. Differences (p<0.001) in ethics-related references were apparent when analysed by continent, publication type, sample size and IF. CONCLUSIONS The majority of published articles pertaining to COVID-19 research made mention of ethical considerations, however, national and regional variations in research ethics review requirements introduce heterogeneity between studies and raise important questions about the conduct of scientific research during global public emergencies.

Abstract
BACKGROUND Screening for problematic opioid use is increasingly recommended in patients receiving palliative care. AIM To identify tools used to assess for the presence or risk of problematic opioid use in palliative care. DESIGN Scoping review. DATA SOURCES Bibliographic databases (inception to January 31, 2020), reference lists, and grey literature were searched to find primary studies reporting on adults receiving palliative care and prescription opioids to manage symptoms from advanced cancer, neurodegenerative diseases, or end-stage organ diseases; and included tools to assess for problematic opioid use. There were no restrictions based on study design, location, or language. RESULTS We identified 42 observational studies (total 14,431 participants) published between 2009 and 2020 that used questionnaires (n = 32) and urine drug tests (n = 21) to assess for problematic opioid use in palliative care, primarily in US (n = 38) and outpatient palliative care settings (n = 36). The questionnaires were Cut down, Annoyed, Guilty, and Eye-opener (CAGE, n = 8), CAGE-Adapted to Include Drugs (CAGE-AID, n = 6), Opioid Risk Tool (n = 9), Screener and Opioid Assessment for Patients with Pain (SOAPP; n = 3), SOAPP-Revised (n = 2), and SOAPP-Short Form (n = 5). Only two studies' primary objectives were to evaluate a questionnaire's psychometric properties in patients receiving palliative care. There was wide variation in how urine drug tests were incorporated into palliative care; frequency of abnormal urine drug test results ranged from 8.6% to 70%. CONCLUSION Given the dearth of studies using tools developed or validated specifically for patients receiving palliative care, further research is needed to inform clinical practice and policy regarding problematic opioid use in palliative care.

Abstract
Background There are limited data regarding the quality of patient‐reported outcome (PRO) data in immune checkpoint inhibitor (ICI) clinical trial publications. Methods A systematic search of citations from various databases was conducted to identify prospective clinical trials involving ICI in advanced tumors from 2003 to 2020. A 30‐point score was adapted from the CONSORT PRO extension statement to assess adherence to CONSORT PRO reporting. Linear regression was used to identify factors associated with quality reporting. Results After the review of 8058 articles, 33 trials were included with ICIs as either monotherapy (91%) or part of a combination regimen (9%). The median score was 23.5 points (range 15–29). In the majority of cases (82%), PROs were reported in a separate publication from the original study. Most of the trials were conducted in the metastatic setting and predominantly in melanoma, lung, and renal cell carcinoma (RCC) (73%). Univariate analysis revealed that trials with greater than 250 patients were associated with a higher score. The score was more likely to be lower in disease sites other than melanoma, lung, and RCC and was higher in the KEYNOTE than in the CHECKMATE trial series. There was no significant correlation between the score and whether a trial met its primary end‐point or if the trial improved or worsened the quality of life. In the multivariate analysis, the number of patients enrolled to the trial, disease site, and trial series remained significant. Conclusions The quality of reporting of PROs in ICI phase II and III clinical trials is heterogeneous across various cancer sites. As PRO data are increasingly used to counsel patients and complement clinical decision making, innovative and collaborative efforts are required to improve the reporting of these essential data.

Abstract
3089 Background: Oncogenic nonV600 BRAF mutations (muts) can be classified according to distinct molecular characteristics. TT strategies for class 2 and 3 BRAF muts have not been established. In recent years there have been numerous reports of clinical activity for various TT in pts with nonV600 muts. We performed a systematic scoping review and meta-analysis to assess treatment outcomes with MAPK TT according to BRAF class, cancer type and TT type. Methods: An extensive literature search was conducted from 2010-20. All studies were independently reviewed and extracted by 2 reviewers and in accordance with PRISMA guidelines. Individual patient level data were collected and analyzed from studies that met the following inclusion criteria: published reports of 1) advanced cancer pts with; 2) class 2 or class 3 nonV600 BRAF muts; 3) who received MAPK TT; 4) with treatment response (TR) data available. Primary outcome was overall TR rate (TRR). To assess differences between groups, odds ratios (OR) were calculated using a multi-level mixed-effects logistic regression model. Results: 15,171 studies were screened and 168 were included for data extraction. We identified 100 studies with a total of 396 pts that met inclusion criteria. There were 17 reports (161 pts) of prospective clinical trials and 83 retrospective studies (235 pts). RECIST criteria were used for TR assessment in 183 (46%) pts. The entire study included 280 pts with class 2 and 116 pts with class 3 BRAF muts. Overall, 111 (28%) pts achieved a TR. TRR according to primary tumor type, BRAF class, and TT type is indicated in Table. TRR was lower in reports of prospective studies compared to retrospective studies (OR 0.14, P = 0.002), and in studies that employed RECIST criteria vs. those that didn’t (OR 0.29, P = 0.044). TRR was higher among pts with class 2 muts vs. those with class 3 muts (OR 2.21, P = 0.042). Conclusions: These data establish that MAPK TT have demonstrated clinical activity in cancers with oncogenic nonV600 mutations, and that BRAF mutation class may dictate responsiveness to different TT strategies. TRR may be over-estimated in the retrospective literature. This analysis will be valuable for molecular tumor boards and to guide future clinical trial design. Prospective clinical trials of TT in this pt population are warranted.[Table: see text]

Abstract
PURPOSE The aim of this scoping review is to understand the motivations for the creation of global medical curricula, summarize methods that have been used to create these curricula, and understand the perceived premises for the creation of these curricula. METHOD In 2018, the authors used a comprehensive search strategy to identify papers on existing efforts to create global medical curricula published from 1998 to March 29, 2018, in the following databases: MEDLINE; MEDLINE Epub Ahead of Print, In-Process, and Other Non-Indexed Citations; Embase; Cochrane Central Register of Controlled Trials; Cochrane Database of Systematic Reviews; PsycINFO; CINAHL; ERIC; Scopus; African Index Medicus; and LILACS. There were no language restrictions. Two independent researchers applied the inclusion and exclusion criteria. Demographic data were abstracted from publications and summarized. The stated purposes, methods used for the development, stated motivations, and reported challenges of curricula were coded. RESULTS Of the 18,684 publications initially identified, 137 met inclusion criteria. The most common stated purposes for creating curricula were to define speciality-specific standards (50, 30%), to harmonize training standards (38, 23%), and to improve the quality or safety of training (31, 19%). The most common challenges were intercountry variation (including differences in health care systems, the operationalization of medical training, and sociocultural differences; 27, 20%), curricular implementation (20, 15%), and the need for a multistakeholder approach (6, 4%). Most curricula were developed by a social group (e.g., committee; 30, 45%) or Delphi or modified Delphi process (22, 33%). CONCLUSIONS The challenges of intercountry variation, the need for a multistakeholder approach, and curricular implementation need to be considered if concerns about curricular relevance are to be addressed. These challenges undoubtedly impact the uptake of global medical curricula and can only be addressed by explicit efforts to make curricula applicable to the realities of diverse health care settings.

Abstract
OBJECTIVES The optimal systemic therapy strategy for advanced epithelial ovarian cancer (EOC) remains unclear. We performed a systematic review and meta-analysis to assess oncologic outcomes and toxicity of bevacizumab combination treatment in advanced EOC. METHODS We conducted an electronic search of all phase 2 and 3 clinical trials involving bevacizumab combination therapy in advanced-stage EOC between 2010 and March 2020, using Embase, Medline, Epub Ahead of Print, Cochrane for clinical trials, Cochrane Database of Systematic Reviews, Web of Science and clinicaltrials.gov databases. Progression-free survival (PFS), overall survival (OS), and their hazard ratios (HR) when available were extracted. Pooled HR were calculated for each efficacy endpoint in the meta-analysis using inverse variance weighted method. Bias was assessed using the Cochrane Collaboration Risk of Bias I (ROB1) tool for randomized controlled trials. RESULTS Thirty-five studies were included in the qualitative analysis and eight studies in the quantitative synthesis. In the first-line setting, bevacizumab combined with chemotherapy revealed a significant improvement in PFS (pooled HR = 0.72, 95% CI 0.65-0.81) when compared to chemotherapy alone but no significant OS benefit (pooled HR = 0.88, 95% CI 0.72-1.06). In the recurrent setting, bevacizumab combinations showed significant PFS (pooled HR = 0.52, 95% CI 0.47-0.58) and OS benefits (pooled HR = 0.88, 95% CI 0.79-0.99) compared with non-bevacizumab regimens. Rate of bowel perforation was low at 1.24% (range 0-4.2%). CONCLUSIONS Bevacizumab-containing regimens are associated with significant PFS benefit in advanced and recurrent epithelial ovarian cancer. While the difference in OS did not reach statistical significance in the first-line setting, bevacizumab was associated with improved survival in the recurrent setting.

Abstract
Importance Active surveillance is sometimes considered as a disease management option for individuals with small, low-risk papillary thyroid carcinoma. Objective To assess whether patient age is associated with progression of low-risk papillary thyroid carcinoma (tumor growth or incident metastatic disease) in adults under active surveillance. Evidence Review Eight electronic databases (MEDLINE, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Emcare, PsycINFO, Web of Science, and ClincalTrials.gov) were searched from inception to March 2019, supplemented with a hand search. Two investigators independently screened citations, reviewed full-text articles, and abstracted data. Additional data were sought from authors. Random-effects meta-analyses were performed using incidence data (statistically adjusted for confounders and crude rates). Findings A total of 1658 unique citations were screened, and 62 full-text articles were reviewed, including 5 studies. Three studies included exclusively microcarcinomas and 2 included tumors up to 2 cm in maximal diameter. The mean age of participants was 51.0 to 55.2 years in 4 studies reporting this value. The mean or median follow-up was 5 years or more in 3 studies and approximately 2 years in 2 studies. The pooled risk ratio for tumor growth of 3 mm or more in maximal diameter in individuals aged 40 to 50 years compared with younger individuals was 0.51 when adjusted for confounders (95% CI, 0.29-0.89; 1619 patients, 2 studies), and the unadjusted risk ratio of this outcome for individuals 40 years or older was 0.55 (95% CI, 0.36-0.82; 2097 patients, 4 studies). In adults aged 40 to 45 years, the unadjusted risk ratio for any tumor volume increase compared with younger individuals was 0.65 (95% CI, 0.51-0.83; 1232 patients, 4 studies). The pooled risk ratio for incident nodal metastases in individuals 40 years or older was 0.22 (95% CI, 0.10-0.47; 1806 patients, 3 studies); however, in a secondary analysis, the risk difference was not significantly different. There was no statistically significant heterogeneity in any of the meta-analyses. There were no thyroid cancer-related deaths nor incident distant metastases. Conclusions and Relevance This study suggests that older age may be associated with a reduced risk of primary papillary thyroid carcinoma tumor growth under active surveillance. Incident metastatic disease is uncommon during active surveillance.

Abstract
BACKGROUND Systemic inflammatory response (SIR) may influence prognosis in epidermal growth factor receptor (EGFR)-mutated (m) non-small-cell lung cancer (NSCLC). Pretreatment SIR markers (neutrophil-to-lymphocyte ratio [NLR], platelet-to-lymphocyte ratio, lymphocyte-to-monocyte ratio [LMR], lactate dehydrogenase [LDH], and lung immune prognostic index [LIPI]) were assessed as prognostic factors in NSCLC survival. PATIENTS AND METHODS Retrospective survival analysis (overall survival [OS] and progression-free survival [PFS]) of EGFR-mutated NSCLC patients at Princess Margaret Cancer Centre were performed separately for early (I-IIIa) and late (IIIb-IV) stage disease for individual SIR variables, dichotomized by optimal cutoff points by Kaplan-Meier survival analysis and multivariable Cox proportional hazard modeling. A systematic review and meta-analysis of known SIR studies in patients with late-stage EGFR-mutated were also performed. RESULTS From 2012 to 2019, in 530 patients, significant adjusted hazard ratios (aHR) for OS comparing high versus low NLR were 2.12 for early stage and 1.79 for late stage disease. Additionally, late stage cohorts had significant associations, as follows: high versus low derived NLR, aHR = 1.53; LMR, aHR = 0.62; LDH, aHR = 2.04; and LIPI, aHR = 2.04. Similar patterns were found for PFS in early stage NLR (aHR = 1.96) and late stage NLR (aHR = 1.46), while for PFS, only late stage derived NLR (aHR = 1.34), LDH (aHR = 1.75), and LIPI (aHR = 1.66) were significant. A meta-analysis confirmed that NLR, LMR, LDH, and LIPI were all significantly associated with OS and PFS in the late stage. CONCLUSION This primary study and meta-analysis demonstrated that LMR and LDH were significantly associated with late stage EGFR-mutated NSCLC outcomes, and the LIPI scoring system was prognostic. NLR remained an independent prognostic factor across all stages and could represent an early marker of immuno-oncology interactions.

Abstract
Abstract
Purpose: The aims of this meta-analysis are to evaluate the diagnostic performance and to explore the optimal timing of post-treatment 18F-FDG PET/CT for HNSCC.
Methods: January 2010 to August 2016 was the range for study selection. Subgroup analyses were performed for local/regional failure stratified by treatment-to-scan time interval of ≤3 vs. >3 months.
Results: Twenty-four studies (2,256 patients) were included. Compared to ≤3 months, 18F-FDG PET/CT performed >3 months showed significantly improved sensitivity (87% vs. 60%, p=0.020) and specificity (93% vs. 84%, p<0.001) for identifying local failure and marginally improved sensitivity for regional failure (79% vs. 56%, p=0.100). The specificity for regional failure was equally high for >3 months vs. ≤3 months (95% vs. 97%, p=0.35).
Conclusions: This meta-analysis showed high NPV but modest PPV for post-treatment 18F-FDG PET/CT for local and regional failure. Sensitivity is improved if performed >3 months for local failure and marginally improved for regional failure.

Abstract
e19121 Background: The programmed cell death 1 (PD-1)/programmed cell death 1 ligand 1 (PD-L1) pathway plays a crucial role in cancer immuno-surveillance and is the target of approved immunotherapeutic drugs. Available data suggest a variable prognostic impact of PD-L1 expression in solid tumors. Methods: A systematic literature search of electronic databases identified publications exploring the effect of PD-L1 on overall survival (OS) and/or progression-free survival (PFS). Hazard ratios (HR) were pooled in a meta-analysis using generic inverse-variance and random effects modeling. Subgroup analyses were conducted based on disease site, stage of disease, and method of PD-L1 quantification using the Deeks method. Results: One hundred eighty-eight studies comprised of 212,748 patients met the inclusion criteria. PD-L1 expression was associated with worse OS (HR 1.32, 95% confidence interval (CI) 1.25 - 1.38; P < 0.001). There was significant heterogeneity between disease sites (subgroup P = 0.002) with pancreatic, hepatocellular and genitourinary cancers being associated with the highest magnitude of adverse outcome (Table). PD-L1 was also associated with worse overall PFS (HR 1.19, 95% CI 1.09 - 1.30; P < 0.001). Stage of disease did not significantly affect the results (subgroup P = 0.52), nor did the method of quantification (immunohistochemistry or mRNA) (subgroup P = 0.70). Conclusions: High expression of PD-L1 is associated with worse cancer outcomes albeit with significant heterogeneity between disease sites. The effect seems consistent in early stage and metastatic disease and is not sensitive to method of PD-L1 quantification. [Table: see text]

Abstract
BACKGROUND Serious concerns regarding quality of conduct and reporting of noninferiority trials (NITs) have been raised. Systematic analysis of the quality of the surgical NITs is lacking. Assessing the quality of conduct, reporting, and interpretation of surgical NITs in cancer patients is critical given their potential clinical impact. We aim to assess the quality of conduct, reporting, and interpretation of NITs that investigate the effects of surgical management in cancer patients. METHODS A cross-sectional analysis of papers identified through a comprehensive literature database search was performed. Forty papers employing a phase III noninferiority (NI) randomized trial design to study effects of surgical methodology or sequencing of surgery in patients with solid cancers were included. Papers were assessed for type of analysis, justification of the noninferiority margin (NIM), consistency of type I error with confidence intervals (CIs), ability to achieve the predefined sample size, and interpretations regarding NI. RESULTS Only half of the papers used both intention-to-treat and per protocol analyses; 62.5% provided no or poor justification for the NIM; 42.5% showed inconsistency of the type I error rate with CIs; 52.5% were deemed poor or fair quality, and 60.0% did not achieve the predefined sample size. One-fifth of the papers provided interpretation of the NI hypothesis that was not in concordance with the CONSORT guidelines. CONCLUSIONS The quality of conduct, reporting, and interpretation of surgical NITs is suboptimal, requiring further improvements through adherence to guidelines and rigorous assessment at the stages of the study approval, funding, and the peer-review process.
