Targeted Screening for Cancer: Learnings and Applicability to Melanoma: A Scoping Review
Abstract This scoping review aims to systematically gather evidence from personalized cancer-screening studies across various cancers, summarize key components and outcomes, and provide implications for a future personalized melanoma-screening strategy. Peer-reviewed articles and clinical trial databases were searched for, with restrictions on language and publication date. Sixteen distinct studies were identified and included in this review. The studies' results were synthesized according to key components, including risk assessment, risk thresholds, screening pathways, and primary outcomes of interest. Studies most frequently reported about breast cancers (n = 7), followed by colorectal (n = 5), prostate (n = 2), lung (n = 1), and ovarian [...]
Quality measures in primary care skin cancer management: a qualitative study of the views of key informants
Abstract Objectives: This study explored potential quality measures to improve skin cancer management in primary care settings, and the barriers and facilitators associated with their implementation. Design: Semistructured interviews and qualitative proforma surveys were conducted with skin cancer experts from a range of healthcare settings. Framework analysis was employed to identify key groups of quality measures within the domains of the Donabedian model of healthcare quality (structure, process, outcome). Interview and survey data were triangulated to identify common groups of quality measures, barriers and facilitators. Participants: We purposively recruited skin cancer experts from Australia and internationally with knowledge and experience in skin [...]
Impact of an Online Risk Calculator for Sentinel Node Positivity on Management of Patients with T1 and T2 Melanomas
Abstract Background: Predicting which patients with American Joint Committee on Cancer (AJCC) T1-T2 melanomas will have a positive sentinel lymph node (SLN) is challenging. Melanoma Institute Australia (MIA) developed an internationally validated SLN metastatic risk calculator. This study evaluated the nomogram's impact on T1-T2 melanoma patient management at MIA. Methods: SLN biopsy (SLNB) rates were compared for the pre- and post-nomogram periods of 1 July 2018-30 June 2019 and 1 August 2020-31 July 2021, respectively. Results: Overall, 850 patients were identified (pre-nomogram, 383; post-nomogram, 467). SLNB was performed in 29.0% of patients in the pre-nomogram group and 34.5% in the post-nomogram group [...]
Public Preferences for Genetic and Genomic Risk-Informed Chronic Disease Screening and Early Detection: A Systematic Review of Discrete Choice Experiments
Abstract Purpose: Genetic and genomic testing can provide valuable information on individuals' risk of chronic diseases, presenting an opportunity for risk-tailored disease screening to improve early detection and health outcomes. The acceptability, uptake and effectiveness of such programmes is dependent on public preferences for the programme features. This study aims to conduct a systematic review of discrete choice experiments assessing preferences for genetic/genomic risk-tailored chronic disease screening. Methods: PubMed, Embase, EconLit and Cochrane Library were searched in October 2023 for discrete choice experiment studies assessing preferences for genetic or genomic risk-tailored chronic disease screening. Eligible studies were double screened, extracted and [...]
Patient demographic characteristics and risk factors associated with sun protection behaviours in specialist melanoma clinics
Abstract Objective: We investigated the association between sun protection behaviours and demographic and melanoma risk characteristics of patients attending Australian melanoma specialist clinics. This may assist in targeting and tailoring melanoma prevention patient education for people at high-risk and specific population subgroups. Methods: A cross-sectional analysis of questionnaire data collected from participants attending the dermatology clinics at two major melanoma centres in Sydney, Australia between February 2021 and September 2023. The primary outcome was Sun Protection Habits (SPH) index (a summary score measured as habitual past month use of sunscreen, hats, sunglasses, a shirt with sleeves that covers the shoulders, limiting [...]
Skin checks for potential skin cancers in general practice in Victoria, Australia: the upfront and downstream patterns and costs.
Abstract Objectives To describe patterns of skin checks for potential skin cancers in general practice and subsequent skin-related healthcare, and the associated costs. Study type Retrospective longitudinal health record linkage. Methods Patient encounters between 2010 and 2017 were extracted from clinical information systems at 73 general practice sites in Victoria, Australia, including Medicare billing information, from the MedicineInsight primary care dataset. The main outcomes were skin checks, skin-related healthcare up to 3 months after the skin check, and health system costs. Results There were 59 046 skin check encounters (0.7% of all general practice encounters) identified for 40 014 [...]

Association of optimism and social support with health-related quality of life among Australian women cancer survivors – A cohort study
Abstract Aim: Large-scale studies investigating health-related quality of life (HRQL) in cancer survivors are limited. This study aims to investigate HRQL and its relation to optimism and social support among Australian women following a cancer diagnosis. Methods: Data were from the Australian Longitudinal Study on Women's Health, a large cohort study (n = 14,715; born 1946-51), with 1428 incident cancer cases ascertained 1996-2017 via linkage to the Australian Cancer Database. HRQL was measured using the Short Form-36 (median 1.7 years post-cancer-diagnosis). Multivariable linear regression was performed on each HRQL domain, separately for all cancers combined, major cancer sites, and cancer-free peers. [...]
Perspectives of health professionals and patients on implementation of a predictive model of response to immunotherapies in advanced melanoma
Abstract Background Immunotherapies have significantly improved the overall survival for patients with advanced melanoma. However, almost half of such patients either do not respond to the therapy or develop resistance to it, subjecting patients to ineffective treatments and unnecessary costs. Predictive biomarker testing can ensure that the patient receives the most effective therapy thereby reducing costs and toxicities. This study was conducted prior to and alongside a clinical validation study of routine predictive biomarker testing for patients with advanced melanoma to gain an insight into the factors associated with successful implementation of this intervention. Methods We conducted semi-structured interviews [...]
Full-body skin examination in screening for cutaneous malignancy: a focus on concealed sites and the practices of Australian dermatologists.
Abstract Background: Full-body skin examination (FSE) is a vital practice in the diagnosis of cutaneous malignancy. Precisely how FSE should be conducted with respect to concealed site inclusion remains poorly elucidated. Objective: To establish the approach of Australian dermatologists to concealed site examination (CSE). Methods: A cross-sectional study was performed consisting of an online self-administered 11-question survey delivered to fellows of the Australasian College of Dermatologists. Results: There were 237 respondents. Anogenitalia was the least often examined concealed site (4.6%), and 59.9, 32.9, and 14.3% reported always examining the scalp, breasts, and oral mucosa, respectively. Patient concern was the most frequently cited factor [...]
