RESUMO

OBJECTIVES: To identify subgroups of patients with distinct cough occurrence profiles and evaluate for differences among these subgroups. SAMPLE & SETTING: Outpatients receiving chemotherapy (N = 1,338) completed questionnaires six times over two chemotherapy cycles. METHODS & VARIABLES: Occurrence of cough was assessed using the Memorial Symptom Assessment Scale. Latent class analysis was used to identify subgroups with distinct cough occurrence profiles. Parametric and nonparametric tests were used to evaluate for differences. RESULTS: Four distinct cough profiles were identified (None, Decreasing, Increasing, and High). Risk factors associated with membership in the High class included lower annual household income; history of smoking; self-reported diagnoses of lung disease, heart disease, and back pain; and having lung cancer. IMPLICATIONS FOR NURSING: Clinicians need to assess all patients with cancer for cough and provide targeted interventions.

RESUMO

BACKGROUND: The number of cancer survivors has increased in recent decades, and the majority of them suffer from sequelae of their disease and treatment. This study, which is part of the larger research project OPTILATER, aims to explore different aspects of care services for long-term survivors (≥ 5 years after initial cancer diagnosis) in Germany. The study places an emphasis on the situation of people from different age groups, with different socio-demographic and cultural backgrounds, and sexually and gender diverse individuals. METHODS: To investigate experiences related to follow-up care, focus groups (n = 2) will be conducted with members of patient advisory councils and advocacy groups, representatives of communities, healthcare workers and networks, as well as members of Associations of Statutory Health Insurance Physicians. Guided interviews will be carried out with patients and relatives (n = 40) to investigate needs, barriers and obstacles in terms of follow-up care. On this basis, additional focus groups (n = 2) will be carried out to derive possible scenarios for improving the consideration of needs. Focus groups and interviews will follow a semi-structured format and will be analysed content-analytically. Focus groups and interviews will be conducted online, recorded, transcribed, and analysed independently by two persons. DISCUSSION: The qualitative approach is considered suitable because of the exploratory research aims. The identification of experiences and barriers can reveal disparities and optimization potential in the care of long-term cancer survivors.

RESUMO

PURPOSE: To apply an independent GPU-accelerated Monte Carlo (MC) dose verification for CyberKnife M6 with Iris collimator and evaluate the dose calculation accuracy of RayTracing (TPS-RT) algorithm and Monte Carlo (TPS-MC) algorithm in the Precision treatment planning system (TPS). METHODS: GPU-accelerated MC algorithm (ArcherQA-CK) was integrated into a commercial dose verification system, ArcherQA, to implement the patient-specific quality assurance in the CyberKnife M6 system. 30 clinical cases (10 cases in head, and 10 cases in chest, and 10 cases in abdomen) were collected in this study. For each case, three different dose calculation methods (TPS-MC, TPS-RT and ArcherQA-CK) were implemented based on the same treatment plan and compared with each other. For evaluation, the 3D global gamma analysis and dose parameters of the target volume and organs at risk (OARs) were analyzed comparatively. RESULTS: For gamma pass rates at the criterion of 2%/2 mm, the results were over 98.0% for TPS-MC vs.TPS-RT, TPS-MC vs. ArcherQA-CK and TPS-RT vs. ArcherQA-CK in head cases, 84.9% for TPS-MC vs.TPS-RT, 98.0% for TPS-MC vs. ArcherQA-CK and 83.3% for TPS-RT vs. ArcherQA-CK in chest cases, 98.2% for TPS-MC vs.TPS-RT, 99.4% for TPS-MC vs. ArcherQA-CK and 94.5% for TPS-RT vs. ArcherQA-CK in abdomen cases. For dose parameters of planning target volume (PTV) in chest cases, the deviations of TPS-RT vs. TPS-MC and ArcherQA-CK vs. TPS-MC had significant difference (P < 0.01), and the deviations of TPS-RT vs. TPS-MC and TPS-RT vs. ArcherQA-CK were similar (P > 0.05). ArcherQA-CK had less calculation time compared with TPS-MC (1.66 min vs. 65.11 min). CONCLUSIONS: Our proposed MC dose engine (ArcherQA-CK) has a high degree of consistency with the Precision TPS-MC algorithm, which can quickly identify the calculation errors of TPS-RT algorithm for some chest cases. ArcherQA-CK can provide accurate patient-specific quality assurance in clinical practice.

RESUMO

PURPOSE: Healthy cancer survivorship involves patients' active engagement with preventative health behaviors and follow-up care. While clinicians and patients have typically held dual responsibility for activating these behaviors, transitioning some clinician effort to technology and health coaches may enhance guideline implementation. This paper reports on the acceptability of the Shared Healthcare Actions & Reflections Electronic systems in survivorship (SHARE-S) program, an entirely virtual multicomponent intervention incorporating e-referrals, remotely-delivered health coaching, and automated text messages to enhance patient self-management and promote healthy survivorship. METHODS: SHARE-S was evaluated in single group hybrid implementation-effectiveness pilot study. Patients were e-referred from the clinical team to health coaches for three health self-management coaching calls and received text messages to enhance coaching. Semi-structured qualitative interviews were conducted with 21 patient participants, 2 referring clinicians, and 2 health coaches to determine intervention acceptability (attitudes, appropriateness, suitability, convenience, and perceived effectiveness) and to identify important elements of the program and potential mechanisms of action to guide future implementation. RESULTS: SHARE-S was described as impactful and convenient. The nondirective, patient-centered health coaching and mindfulness exercises were deemed most acceptable; text messages were less acceptable. Stakeholders suggested increased flexibility in format, frequency, timing, and length of participation, and additional tailored educational materials. Patients reported tangible health behavior changes, improved mood, and increased accountability and self-efficacy. CONCLUSIONS: SHARE-S is overall an acceptable and potentially effective intervention that may enhance survivors' self-management and well-being. Alterations to tailored content, timing, and dose should be tested to determine impact on acceptability and outcomes.

RESUMO

Importance: Current research in epigenetic age acceleration (EAA) is limited to non-Hispanic White individuals. It is imperative to improve inclusivity by considering racial and ethnic minorities in EAA research. Objective: To compare non-Hispanic Black with non-Hispanic White survivors of childhood cancer by examining the associations of EAA with cancer treatment exposures, potential racial and ethnic disparity in EAA, and mediating roles of social determinants of health (SDOH). Design, Setting, and Participants: In this cross-sectional study, participants were from the St Jude Lifetime Cohort, which was initiated in 2007 with ongoing follow-up. Eligible participants included non-Hispanic Black and non-Hispanic White survivors of childhood cancer treated at St Jude Children's Research Hospital between 1962 and 2012 who had DNA methylation data. Data analysis was conducted from February 2023 to May 2024. Exposure: Three treatment exposures for childhood cancer (chest radiotherapy, alkylating agents, and epipodophyllotoxin). Main Outcomes and Measures: DNA methylation was generated from peripheral blood mononuclear cell-derived DNA. EAA was calculated as residuals from regressing Levine or Horvath epigenetic age on chronological age. SDOH included educational attainment, annual personal income, and the socioeconomic area deprivation index (ADI). General linear models evaluated cross-sectional associations of EAA with race and ethnicity (non-Hispanic Black and non-Hispanic White) and/or SDOH, adjusting for sex, body mass index, smoking, and cancer treatments. Adjusted least square means (ALSM) of EAA were calculated for group comparisons. Mediation analysis treated SDOH as mediators with average causal mediation effect (ACME) calculated for the association of EAA with race and ethnicity. Results: Among a total of 1706 survivors including 230 non-Hispanic Black survivors (median [IQR] age at diagnosis, 9.5 [4.3-14.3] years; 103 male [44.8%] and 127 female [55.2%]) and 1476 non-Hispanic White survivors (median [IQR] age at diagnosis, 9.3 [3.9-14.6] years; 766 male [51.9%] and 710 female [48.1%]), EAA was significantly greater among non-Hispanic Black survivors (ALSM = 1.41; 95% CI, 0.66 to 2.16) than non-Hispanic White survivors (ALSM = 0.47; 95% CI, 0.12 to 0.81). Among non-Hispanic Black survivors, EAA was significantly increased among those exposed to chest radiotherapy (ALSM = 2.82; 95% CI, 1.37 to 4.26) vs those unexposed (ALSM = 0.46; 95% CI, -0.60 to 1.51), among those exposed to alkylating agents (ALSM = 2.33; 95% CI, 1.21 to 3.45) vs those unexposed (ALSM = 0.95; 95% CI, -0.38 to 2.27), and among those exposed to epipodophyllotoxins (ALSM = 2.83; 95% CI, 1.27 to 4.40) vs those unexposed (ALSM = 0.44; 95% CI, -0.52 to 1.40). The association of EAA with epipodophyllotoxins differed by race and ethnicity (ß for non-Hispanic Black survivors, 2.39 years; 95% CI, 0.74 to 4.04 years; ß for non-Hispanic White survivors, 0.68; 95% CI, 0.05 to 1.31 years) and the difference was significant (1.77 years; 95% CI, 0.01 to 3.53 years; P for interaction = .049). Racial and ethnic disparities in EAA were mediated by educational attainment (

RESUMO

BACKGROUND: As cancer centers have increased focus on patient-centered, evidenced-based care, implementing efficient programs that facilitate effective patient-clinician communication remains critical. We implemented an electronic health record-integrated patient-reported symptom and needs monitoring program ('cPRO' for cancer patient-reported outcomes). To aid evaluation of cPRO implementation, we asked patients receiving care in one of three geographical regions of an academic healthcare system about their experiences. METHODS: Using a sequential mixed-methods approach, we collected feedback in two waves. Wave 1 included virtual focus groups and interviews with patients who had completed cPRO. In Wave 2, we administered a structured survey to systematically examine Wave 1 themes. All participants had a diagnosed malignancy and received at least 2 invitations to complete cPRO. We used rapid and traditional qualitative methods to analyze Wave 1 data and focused on identifying facilitators and barriers to cPRO implementation. Wave 2 data were analyzed descriptively. RESULTS: Participants (n = 180) were on average 62.9 years old; were majority female, White, non-Hispanic, and married; and represented various cancer types and phases of treatment. Wave 1 participants (n = 37) identified facilitators, including cPRO's perceived value and favorable usability, and barriers, including confusion about cPRO's purpose and various considerations for responding. High levels of clinician engagement with, and patient education on, cPRO were described as facilitators while low levels were described as barriers. Wave 2 (n = 143) data demonstrated high endorsement rates of cPRO's usability on domains such as navigability (91.6%), comprehensibility (98.7%), and relevance (82.4%). Wave 2 data also indicated low rates of understanding cPRO's purpose (56.7%), education from care teams about cPRO (22.5%), and discussing results of cPRO with care teams (16.3%). CONCLUSIONS: While patients reported high value and ease of use when completing cPRO, they also reported areas of confusion, emphasizing the importance of patient education on the purpose and use of cPRO and clinician engagement to sustain participation. These results guided successful implementation changes and will inform future improvements.

RESUMO

Delivering cancer control at scale for Aboriginal and Torres Strait Islander communities is a national priority that requires Aboriginal and Torres Strait Islander leadership and codesign, as well as significant involvement of the Aboriginal community-controlled health sector. The unique genomic variation observed among Aboriginal and Torres Strait Islander peoples may have implications for standard and precision medicine. Yet, Aboriginal and Torres Strait Islander peoples are absent from, or under-represented within, human reference genome resources, genomic studies, cancer studies, cancer cell lines, patient-derived xenografts and cancer clinical trials. Genomics-guided precision cancer medicine offers an opportunity to reduce cancer health disparities experienced by Aboriginal and Torres Strait Islander peoples through personalising prevention, diagnosis, treatment and long term management. Here, we describe what is required to ensure that Aboriginal and Torres Strait Islander peoples can receive the benefits of precision cancer medicine. Equity of access to care, an Aboriginal and Torres Strait Islander cancer workforce, and appropriate genome reference resources are important for safe and effective cancer medicine. Building Indigenous data sovereignty principles and Aboriginal and Torres Strait Islander governance into research is required to protect Aboriginal and Torres Strait Islander rights and collective interests. Aboriginal and Torres Strait Islander community engagement should be undertaken to develop an understanding of the unique cultural and ethical considerations for precision cancer research. Local and national genomic health research guidelines are needed to define a consensus best practice in genomics research with Aboriginal and Torres Strait Islander peoples.

RESUMO

PURPOSE: Rare cancers constitute over 20% of human neoplasms, often affecting patients with unmet medical needs. The development of effective classification and prognostication systems is crucial to improve the decision-making process and drive innovative treatment strategies. We have created and implemented MOSAIC, an artificial intelligence (AI)-based framework designed for multimodal analysis, classification, and personalized prognostic assessment in rare cancers. Clinical validation was performed on myelodysplastic syndrome (MDS), a rare hematologic cancer with clinical and genomic heterogeneities. METHODS: We analyzed 4,427 patients with MDS divided into training and validation cohorts. Deep learning methods were applied to integrate and impute clinical/genomic features. Clustering was performed by combining Uniform Manifold Approximation and Projection for Dimension Reduction + Hierarchical Density-Based Spatial Clustering of Applications with Noise (UMAP + HDBSCAN) methods, compared with the conventional Hierarchical Dirichlet Process (HDP). Linear and AI-based nonlinear approaches were compared for survival prediction. Explainable AI (Shapley Additive Explanations approach [SHAP]) and federated learning were used to improve the interpretation and the performance of the clinical models, integrating them into distributed infrastructure. RESULTS: UMAP + HDBSCAN clustering obtained a more granular patient stratification, achieving a higher average silhouette coefficient (0.16) with respect to HDP (0.01) and higher balanced accuracy in cluster classification by Random Forest (92.7% ± 1.3% and 85.8% ± 0.8%). AI methods for survival prediction outperform conventional statistical techniques and the reference prognostic tool for MDS. Nonlinear Gradient Boosting Survival stands in the internal (Concordance-Index [C-Index], 0.77; SD, 0.01) and external validation (C-Index, 0.74; SD, 0.02). SHAP analysis revealed that similar features drove patients' subgroups and outcomes in both training and validation cohorts. Federated implementation improved the accuracy of developed models. CONCLUSION: MOSAIC provides an explainable and robust framework to optimize classification and prognostic assessment of rare cancers. AI-based approaches demonstrated superior accuracy in capturing genomic similarities and providing individual prognostic information compared with conventional statistical methods. Its federated implementation ensures broad clinical application, guaranteeing high performance and data protection.

RESUMO

BACKGROUND: Patients with metastatic cancer experience high healthcare use and costs, most of which are unplanned. We aimed to assess whether patients with more competent informal caregivers have lower unplanned healthcare use and costs. METHODS: This study used data from a prospective cohort of patients with solid metastatic cancer. Patients and their informal family caregivers were surveyed every 3 months until patients' death. Patients' unplanned healthcare use/costs were examined through hospital records. Caregivers responded to the 4-item Caregiver Competence Scale. First, in a deceased subsample of patients and their caregivers, we used patients' last 2 years of data (226 dyads) to assess the association between caregivers' competency (independent variable) and patients' unplanned healthcare use/costs (outcomes). Next, in a prospective sample of patient-caregiver dyads (up to 15 surveys), we assessed whether patients' functional well-being and psychological distress moderated the association between caregivers' competency and unplanned healthcare use/costs (311 dyads). RESULTS: In the deceased subsample, during last 2 years of patients' life, caregivers' higher competency lowered the odds of patients' unplanned healthcare use [OR (CI) = 0.86 (0.75, 0.98), p = 0.03], and was associated with a significant reduction in unplanned healthcare costs [Coeff (CI) = -0.19 (-0.36, -0.01), p = 0.03]. In the prospective sample, patients' functional well-being and psychological distress moderated the association between caregivers' competency and patients' unplanned healthcare use/costs. CONCLUSION: With deterioration in patients' condition and an increase in caregiving demands, improving caregivers' competency can reduce patients' unplanned healthcare use and costs. This should be further tested in future trials.

RESUMO

BACKGROUND: Patients with fewer socioeconomic and health literacy resources are disadvantaged in their access and use of healthcare, which may give rise to worse experiences with care and thus inequalities in patient experiences. However, only a limited number of studies have examined how socioeconomic and health literacy factors shape inequalities in patients' experiences with cancer care. OBJECTIVE: To examine whether patients' experiences with cancer care differ according to their economic status and health literacy. METHODS: Secondary analysis of data on 2789 adult patients diagnosed with cancer from the Swiss Cancer Patient Experiences-2 (SCAPE-2) study, a cross-sectional survey conducted in eight hospitals across Switzerland from September 2021 to February 2022. Regression analysis was applied to examine the independent effect of patients' economic status and health literacy on various outcomes of experiences with cancer care, covering eight different dimensions of patient-centred care, controlling for confounding factors. RESULTS: Adjusted regression analysis showed that patients with lower economic status reported significantly worse experiences with cancer care in 12 out of 29 specific care experiences, especially in the dimensions of 'respect for patients' preferences' and 'physical comfort' where all items of experiences were associated with economic status. Additionally, lower health literacy was associated with worse patient experiences in 23 specific care experiences. All items in the dimensions of 'respect for patients' preferences', 'physical comfort' and 'emotional support' were associated with health literacy. DISCUSSION: This study revealed significant inequalities in experiences with cancer care shaped by the economic status and health literacy of patients across different dimensions of patient-centred care. It is essential to address the needs of more disadvantaged patients who face obstacles in their access and use of the healthcare system, not only to mitigate inequalities in cancer care but also to avoid inequalities in health outcomes.

RESUMO

According to data from the World Health Organization (WHO), cancer is considered to be one of the leading causes of death worldwide, and new therapeutic approaches, especially improved novel cancer treatment regimens, are in high demand. Considering that many chemotherapeutic drugs tend to have poor pharmacokinetic profiles, including rapid clearance and limited on-site accumulation, a combined approach with tumor-homing peptide (THP)-functionalized magnetic nanoparticles could lead to remarkable improvements. This is confirmed by an increasing number of papers in this field, showing that the on-target peptide functionalization of magnetic nanoparticles improves their penetration properties and ensures tumor-specific binding, which results in an increased clinical response. This review aims to highlight the potential applications of THPs in combination with magnetic carriers across various fields, including a pharmacoeconomic perspective.

RESUMO

OBJECTIVES: To determine the incidence, presentation, frequency and management of immune checkpoint inhibitors (ICI)-related endocrinopathies in a comprehensive cancer centre in Oman, particularly with programme death 1/programme death-ligand 1 (PD-1/PD-L1) inhibitors. BACKGROUND: A high number of patients treated with PD-1/PD-L1 inhibitors for the management of solid tumours developed endocrinopathies. METHODS: This is a retrospective study of patients admitted to Sultan Qaboos Comprehensive Cancer Care and Research Centre (SQCCCRC) from August 2021 to December 2022. All adults diagnosed with solid cancers and have received at least one dose of ICIs were included. Patients with incomplete data were excluded from the analysis. Data regarding the ICI-induced endocrinopathy were collected. RESULTS: A total of 139 patients were included in the study of which 58% were females. The median age of the cohort was 56 years. The incidence of endocrine-related adverse events was 28%. The mean time for the development of endocrine adverse events after treatment initiation was 4.1 ± 2.8 months. Of the patients who developed toxicity, 90% had hypothyroidism. Ten patients developed hyperthyroidism, two patients were diagnosed with secondary adrenal insufficiency/hypophysitis and one patient developed Type 1 diabetes mellitus (DM). Using univariable logistic regression weight and body mass index (BMI) significantly impacted the development of endocrine immune-related adverse events (irAEs). CONCLUSIONS: This is the first study from the Sultanate of Oman to assess PD-1/PDL-1 ICI-induced endocrinopathies. The most common endocrine adverse event is thyroid dysfunction, mainly hypothyroidism followed by hyperthyroidism. Hypophysitis, primary adrenal insufficiency and CIADM occur less frequently, but have a more significant effect on the patient's health. The treating physician should be aware of ICI-induced endocrinopathies, screening and treatment. Furthermore, our study showed that patients with a higher BMI have a greater risk of developing irAES. Further studies are needed to establish the predictors of endocrine irAEs.

RESUMO

Nanomaterials have been extensively exploited in tumor treatment, leading to numerous innovative strategies for cancer therapy. While nanomedicines present immense potential, their application in cancer therapy is characterized by significant complexity and unpredictability, especially regarding biocompatibility and anticancer efficiency. These considerations underscore the essential need for the development of ex vivo research models, which provide invaluable insights and understanding into the biosafety and efficacy of nanomedicines in oncology. Fortunately, the emergence of organoid technology offers a novel approach to the preclinical evaluation of the anticancer efficacy of nanomedicines in vitro. Hence, in this study, we constructed intestine and hepatocyte organoid models (Intestine-orgs and Hep-orgs) for assessing intestinal and hepatic toxicity at the microtissue level. We utilized three typical metal-organic frameworks (MOFs), ZIF-8, ZIF-67, and MIL-125, as nanomedicines to further detect their interactions with organoids. Subsequently, the MIL-125 with biocompatibility loaded methotrexate (MTX), forming the nanomedicine (MIL-125-PEG-MTX), indicated a high loading efficiency (82%) and a well-release capability in an acid microenvironment. More importantly, the anticancer effect of the nanomedicine was investigated using an in vitro patient-derived organoids (PDOs) model, achieving inhibition rates of 48% and 78% for PDO-1 and PDO-2, respectively, demonstrating that PDOs could predict clinical response and facilitate prospective therapeutic selection. These achievements presented great potential for organoid-based ex vivo models for nano theragnostic evaluation in biosafety and function.

RESUMO

BACKGROUND: Human papillomavirus (HPV) causes several cancers such as cervical cancer and some head and neck (oral cavity, pharynx, and larynx), vulval, vaginal, anal, and penile cancers. As HPV vaccination is available, there is potential to prevent these cancers attributed to HPV and consequently the burden associated with them. The aim of this analysis was to estimate the number of HPV-related cancer deaths and the productivity costs due to years of life lost (YLL) in the United Kingdom (UK). METHOD: A model was developed utilizing UK 2019 mortality data sourced from country-specific databases for England, Scotland, Wales, and Northern Ireland for the following HPV-related cancers: head and neck (ICD-10 C00-14 and C32), cervix uteri (C53), vaginal (C51), vulval (C52), anal (C21), and penile (C60). The proportion of deaths and years of life lost (YLL) due to HPV were estimated using HPV attributable fractions for each anatomic location from the published literature. Labor force participation, retirement ages, and mean annual earnings, discounted at 3.5% annually, were applied to YLL to calculate the present value of future lost productivity (PVFLP). RESULTS: A total of 1817 deaths due to HPV-related cancers were reported in the UK in 2019 resulting in 31,804 YLL. Restricting to only YLL that occurred prior to retirement age yielded a total YPLL of 11,765 and a total PVFLP of £187,764,978. CONCLUSIONS: There is a high disease burden in the UK for HPV-related cancers, with a large economic impact on the wider economy due to productivity losses. Implementing and reinforcing public health measures to maintain high HPV vaccination coverage in both males and females may further facilitate reduction of this burden.

RESUMO

Racism has been a long-standing influential factor that has negatively impacted both past and current health disparities within the United Sates population. Existing problems of racism and its impact on both health disparities and health inequalities were only amplified during the COVID-19 pandemic. The pandemic allowed both clinicians and researchers to recognize a growing list of health concerns at the macro-, meso-, and micro-level among underserved racially minoritized patients with specific chronic illnesses such as cancer. Based on these concerns, this Special Issue was designed to highlight the challenges of cancer screening, cancer treatment, and cancer-centered educational outreach among racially minoritized communities.

RESUMO

Ovarian transposition (OT) has been proposed as a protective measure against radiation-induced damage to ovarian function and fertility. Despite its historical use, limited research has focused on evaluating endocrine and exocrine ovarian function after OT performed in adolescents and young adults (AYAs) before or during puberty. The purpose of our study was to investigate the fertility, pubertal development, and ovarian function of women with a previous history of OT during childhood, adolescence or young adulthood. In an observational bicentric retrospective study, we included 32 young female cancer patients who underwent OT before the age of 26 between 1990 and 2015 at Lyon Léon Bérard Cancer Center or Nancy University Hospital. The mean age at the time of OT was 15.6 years with a cancer diagnosis at 15 ± 4.8 years. Among the 10 women attempting pregnancy post-treatment, 60% achieved successful pregnancies. After a mean follow-up of 9.6 ± 7 years, 74% (17 out of 23) of women recovered spontaneous menstrual cycles (seven out of eight evaluable women with OT before or during puberty). Notably, 35% of women who did not attempt pregnancy demonstrated adequate ovarian reserve. Ovarian reserve and function recovery were influenced by the specific chemotherapy received. Importantly, our findings suggest that OT's effectiveness on ovarian activity resumption does not significantly differ when performed before or during puberty compared to pubertal stages. This study contributes valuable insights into the long-term reproductive outcomes of young women undergoing OT, emphasizing its potential efficacy in preserving ovarian function and fertility across different developmental stages.

RESUMO

The COVID-19 pandemic placed a spotlight on the potential to dramatically increase the use of telehealth across the cancer care continuum, but whether and how telehealth can be implemented in practice in ways that reduce, rather than exacerbate, inequities are largely unknown. To help fill this critical gap in research and practice, we developed the Framework for Integrating Telehealth Equitably (FITE), a process and evaluation model designed to help guide equitable integration of telehealth into practice. In this manuscript, we present FITE and showcase how investigators across the National Cancer Institute's Telehealth Research Centers of Excellence are applying the framework in different ways to advance digital and health equity. By highlighting multilevel determinants of digital equity that span further than access alone, FITE highlights the complex and differential ways structural determinants restrict or enable digital equity at the individual and community level. As such, achieving digital equity will require strategies designed to not only support individual behavior but also change the broader context to ensure all patients and communities have the choice, opportunity, and resources to use telehealth across the cancer care continuum.
