Abstract
In the first article in this continuing medical education series we review controversies and uncertainties relating to the epidemiology and initial diagnosis of localized cutaneous melanoma (ie, stage 0, I, or II). Many of these issues are unsettled because of conflicting evidence. Melanoma incidence appears to be increasing, yet its basis has not been fully explained. Despite the advantages of early detection, the US Preventive Services Task Force does not recommend skin screening for the general population. Occasionally, biopsy specimens of melanoma will show histologic regression, but the prognostic importance of this phenomenon is uncertain. Some practitioners recommend obtaining a sentinel lymph node biopsy specimen for thin melanomas showing regression, although this histologic finding is not part of the staging system for thin melanomas. Our goal is to provide the clinician who cares for patients with (or at risk for) melanoma with up-to-date contextual knowledge to appreciate the multiple sides of each controversy so that they will be better informed to discuss these issues with their patients and their families.

Long-term Cardiovascular Outcomes Among Endometrial Cancer Survivors in a Large, Population-Based Cohort Study. J Natl Cancer Inst 2018; 110:1342-1351. [PMID: 29741696 PMCID: PMC6292788 DOI: 10.1093/jnci/djy070] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2017] [Revised: 01/13/2018] [Accepted: 03/16/2018] [Indexed: 08/10/2023] Open
Abstract
BACKGROUND Endometrial cancer is the second most common cancer among female cancer survivors in the United States. Cardiovascular disease is the leading cause of death among endometrial cancer survivors. Studies that examine long-term cardiovascular outcomes among endometrial cancer survivors are critical. METHODS Cohorts of 2648 endometrial cancer survivors diagnosed between 1997 and 2012 and 10 503 age-matched women from the general population were identified. Cardiovascular disease diagnoses were identified from electronic medical records and statewide ambulatory surgery and statewide inpatient data. Cox regression models were used to estimate hazard ratios (HRs) at one to five years, more than five to 10 years, and more than 10 years after cancer diagnosis. RESULTS Between one and five years after diagnosis, increased cardiovascular risks among endometrial cancer survivors were observed for phlebitis, thrombophlebitis, and thromboembolism (HR = 2.07, 99% confidence interval [CI] = 1.57 to 2.72), pulmonary heart disease (HR = 1.74, 99% CI = 1.26 to 2.40), and atrial fibrillation (HR = 1.50, 99% CI = 1.07 to 2.11). At more than five to 10 years, some elevated risk persisted for cardiovascular diseases. Compared with patients who had surgery, patients who additionally had radiation therapy and/or chemotherapy were at increased risk for heart and circulatory system disorders between one and five years after cancer diagnosis. Older age and obesity were also risk factors for hypertension and heart disease among endometrial cancer survivors. CONCLUSIONS Endometrial cancer survivors are at higher risk for various adverse long-term cardiovascular outcomes compared with women from the general population. This study suggests that increased monitoring for cardiovascular diseases may be necessary for endometrial cancer patients for 10 years after cancer diagnosis.

Abstract
OBJECTIVES To explore patterns of communication among families with a Lynch syndrome diagnosis and understand what resources could facilitate family communication. METHODS 127 probands (i.e., first person in family with identified mutation) and family members participated in semi-structured interviews about: how they learned about the Lynch syndrome diagnosis, with whom they shared genetic test results, confidence in sharing results with other family members, and helpfulness of educational resources. RESULTS Both probands and family members were most likely to share genetic test results with parents and siblings, and least likely to share results with aunts, uncles, and cousins. Most participants felt very confident sharing their test results with family members, but reported that certain topics such as cancer risk were challenging to convey. Probands reported the most helpful resources to be access to a specialty clinic or website, while family members described general printed materials as most helpful. CONCLUSIONS Families affected by Lynch syndrome may experience barriers to communication with more distant relatives, and may benefit from receiving specific resources (e.g., websites about Lynch syndrome, print materials) to facilitate family communication. PRACTICE IMPLICATIONS Providers could emphasize the need to share information with more distant family members and provide appropriate supportive resources.

Abstract
PURPOSE This study evaluated oral medication adherence among adolescents and young adults (AYAs) with cancer during a trial of a smartphone-based medication reminder application (app). METHODS Twenty-three AYAs receiving at least one prescribed, scheduled oral medication related to their outpatient cancer treatment participated in this 12-week single-group interrupted time series longitudinal design study. Baseline oral medication adherence was monitored using electronic monitoring caps for 4 weeks. Participants then used a medication reminder app and continued to have their oral medication adherence monitored for 8 weeks. Participants completed an electronically administered weekly survey addressing perceived adherence and reasons for nonadherence. RESULTS Four adherence phenotypes were identified using visual graphical analysis of individual participants' weekly adherence: (1) high adherence during the preintervention and intervention periods (n = 13), (2) low preintervention adherence and improved adherence during the intervention period (n = 3), (3) low adherence during both periods (n = 6), and (4) high preintervention adherence and low adherence during the intervention period (n = 1). Growth curve models did not show significant changes in adherence by preintervention versus intervention trajectories (p > 0.05); however, the variance in adherence during the intervention narrowed for more highly adherent AYAs. "Forgetfulness" was the most frequently reported reason for nonadherence. CONCLUSION Although overall adherence did not improve following use of the app, the variance decreased for more highly adherent participants. Additional or alternative interventions are needed for AYAs with persistently poor adherence. Assessment of adherence patterns may support individualized recommendation of tailored interventions.

Abstract
INTRODUCTION Informal family caregivers (FCG) are an integral and crucial human component in the cancer care continuum. However, research and interventions to help alleviate documented anxiety and burden on this group is lacking. To address the absence of effective interventions, we developed the electronic Support Network Assessment Program (eSNAP) which aims to automate the capture and visualization of social support, an important target for overall FCG support. This study seeks to describe the preliminary efficacy and outcomes of the eSNAP intervention. METHODS Forty FCGs were enrolled into a longitudinal, two-group randomized design to compare the eSNAP intervention in caregivers of patients with primary brain tumors against controls who did not receive the intervention. Participants were followed for six weeks with questionnaires to assess demographics, caregiver burden, anxiety, depression, and social support. Questionnaires given at baseline (T1) and then 3-weeks (T2), and 6-weeks (T3) post baseline questionnaire. RESULTS FCGs reported high caregiver burden and distress at baseline, with burden remaining stable over the course of the study. The intervention group was significantly less depressed, but anxiety remained stable across groups. CONCLUSIONS With the lessons learned and feedback obtained from FCGs, this study is the first step to developing an effective social support intervention to support FCGs and healthcare providers in improving cancer care.

Abstract
Social media as an effective source of information and support among parents and other caregivers of children with cancer has not been explored. The purpose of this cross-sectional study was to describe caregivers' reasons for using social media, social media sites used, and predictors of social media usage. This study sample included 215 caregivers (96% parents) of children with cancer receiving cancer-related care at a tertiary children's hospital in the Intermountain West. Most of caregivers (74%) reported using social media in relation to their child's cancer and reported using social media to provide and receive support and information about their child's diagnosis or treatment. Our findings suggest that social media could be a delivery platform for future interventions seeking to meet the informational and emotional needs of caregivers of children with cancer. An awareness of how parents and caregivers of children receiving cancer-related treatment use social media can help nurses understand their ongoing informational and emotional needs. Nurses can also support parents and caregivers in selecting reputable sources of support that are accessible via social media.

Abstract
Genetic testing of minors is advised only for conditions in which benefits of early intervention outweigh potential psychological harms. This study investigated whether genetic counseling and test reporting for the CDKN2A/p16 mutation, which confers highly elevated melanoma risk, improved sun protection without inducing distress. Eighteen minors (Mage = 12.4, SD = 1.9) from melanoma-prone families completed measures of protective behavior and distress at baseline, 1 week (distress only), 1 month, and 1 year following test disclosure. Participants and their mothers were individually interviewed on the psychological and behavioral impact of genetic testing 1 month and 1 year post-disclosure. Carriers (n = 9) and noncarriers (n = 9) reported significantly fewer sunburns and a greater proportion reported sun protection adherence between baseline and 1 year post-disclosure; results did not vary by mutation status. Anxiety symptoms remained low post-disclosure, while depressive symptoms and cancer worry decreased. Child and parent interviews corroborated these findings. Mothers indicated that genetic testing was beneficial (100%) because it promoted risk awareness (90.9%) and sun protection (81.8%) without making their children scared (89.9%); several noted their child's greater independent practice of sun protection (45.4%). In this small initial study, minors undergoing CDKN2A/p16 genetic testing reported behavioral improvements and consistently low distress, suggesting such testing may be safely implemented early in life, allowing greater opportunity for risk-reducing lifestyle changes.

Abstract
Efforts to prevent melanoma, especially for those at elevated risk for the disease, should ideally begin during childhood. However, there are few preventive interventions targeting children who are at higher risk for melanoma due to a family history of the disease. Further, there are no educational interventions that aim to help these at-risk children understand their risk for melanoma and the ways in which preventive behaviors, such as sun protection, can mitigate their risk. The current paper describes a multidisciplinary team's process for creating a developmentally appropriate educational intervention about melanoma risk and prevention for children ages 8-17 years who have a family history of melanoma. Drawing from the fields of dermatology, health behavior change and education, genetic risk communication, science education, and graphic arts, the multimedia intervention created covers key learning points relevant to understanding melanoma, the role of DNA damage in melanoma development, inherited risk factors for melanoma, environmental factors causing DNA damage, and methods for preventing DNA damage, such as sun protective behaviors. Lessons learned during the development of the educational intervention, particularly relevant to multidisciplinary team interactions, are discussed. Implications for future testing and refinement of the novel educational content are also reviewed.

Abstract
In radiation pressure ion acceleration (RPA) research, the transverse stability within laser plasma interaction has been a long-standing, crucial problem over the past decades. In this paper, we present a one-dimensional two-fluid theory extended from a recent work Wan et al. Phys. Rev. Lett. 117, 234801 (2016)PRLTAO0031-900710.1103/PhysRevLett.117.234801 to clearly clarify the origin of the intrinsic transverse instability in the RPA process. It is demonstrated that the purely growing density fluctuations are more likely induced due to the strong coupling between the fast oscillating electrons and quasistatic ions via the ponderomotive force with spatial variations. The theory contains a full analysis of both electrostatic (ES) and electromagnetic modes and confirms that the ES mode actually dominates the whole RPA process at the early linear stage. By using this theory one can predict the mode structure and growth rate of the transverse instability in terms of a wide range of laser plasma parameters. Two-dimensional particle-in-cell simulations are systematically carried out to verify the theory and formulas in different regimes, and good agreements have been obtained, indicating that the electron-ion coupled instability is the major factor that contributes the transverse breakup of the target in RPA process.

Abstract
Objective: To determine the influence of urethral fibrosis on the recovery of urinary continence after laparoscopic radical prostatectomy. Method: A retrospective study of 203 patients from January 2010 to January 2014 who were underwent laparoscopic radical prostatectomy for prostate cancer in the First Affiliated Hospital of Fujian Medical University. The patients were divided into 2 groups according to preoperative T2-weighted magnetic resonance imaging of fibrosis status of the urethral wall and periurethral tissue. One hundred and forty-four(≤2 grade) and 59 (≥3 grade) were classified into the no/mild and severe urethral fibrosis groups respectively. Urinary continence at 1, 3, 6, 12 months after operation were compared between this two groups respectively. Result: There was no significant difference in the two groups with respect to age, body mass index (BMI), Charlson comorbidity index (CCI), international prostate symptom score (IPSS), prostate volume, preoperative prostate-specific antigen value, nerve-sparing procedure, postoperative Gleason score and pathological stage. The operation was completed successfully in all cases. With a median follow-up time of 15 months (ranged from 12 to 24 months), there was no statistical difference between the two groups in urinary continence at 1 month after operation (P>0.05). The incidences of continence in patients with no/mild fibrosis were significantly higher at 3, 6, 12 months after operation than those with severe fibrosis. (In the no/mild fibrosis group and severe fibrosis group, the continue rate at 3 mouths was 50.0% vs 28.8% P=0.005; at 6 mouths was 91.0% vs 59.3% P<0.001; at 12 mouths was 98.6% vs 88.1% P=0.003). Conclusion: Preoperative urethral fibrosis could be a significant predictor of recovery of the long-term urinary continence status after laparoscopic radical prostatectomy. Compared with no/mild fibrosis, severe fibrosis had worse long-term continence status.

Abstract
This study explored whether and how childhood cancer survivors in Korea ask and resolve the question of what may have caused their cancer. Thirty-one childhood cancer survivors participated in in-depth interviews about their self-questioning process in this regard. The findings indicate that Korean childhood cancer survivors pondered this question alone due to the stigma attached to cancer in the family and society. Their answers included internal factors (doing "bad things," having unhealthy eating habits, engaging in magical thinking, having a stress-prone personality, or having a biological susceptibility) or external factors (stressors, random events, the environment, or medical conditions). How they perceived the cause of cancer had an impact on aspects of their current lives. Psychosocial care standards or guidelines are needed in regard to the provision of a safe environment in which Korean cancer survivors and their parents can share their perceptions and process their thoughts.

Abstract
OBJECTIVE To examine the acceptability of and preliminary effects associated with a novel educational intervention for children at elevated risk for melanoma. The intervention incorporated information on mechanisms through which melanoma preventive behaviors mitigate risk for melanoma and was delivered to parents and children concurrently. METHODS Twenty-two parents (with a personal history of melanoma or spouse with a history of melanoma) and 33 children (mean age 11.8 years) were asked to complete questionnaires immediately prior to and after an educational session and at a one-month follow-up. RESULTS Both parents and children endorsed that the educational materials were acceptable. Knowledge about melanoma risk and preventive and screening behaviors increased significantly. Children's perceived risk for melanoma increased significantly, while parents' perceptions of children's risk started at a higher level and remained constant. There were significant increases in reported engagement in sun protective behaviors. CONCLUSION The educational intervention shows promise in terms of its acceptability and effects on participant knowledge, perceived risk, and engagement in melanoma preventive behaviors. PRACTICE IMPLICATION Children at elevated risk for melanoma and their parents may benefit from receiving educational information on their disease risk and strategies for prevention and screening.

Abstract
Assessments of cancer survivors' health-related needs are often limited to national estimates. State-specific information is vital to inform state comprehensive cancer control efforts developed to support patients and providers. We investigated demographics, health status/quality of life, health behaviors, and health care characteristics of long-term Utah cancer survivors compared to Utahans without a history of cancer. Utah Behavioral Risk Factor Surveillance System (BRFSS) 2009 and 2010 data were used. Individuals diagnosed with cancer within the past 5 years were excluded. Multivariable survey weighted logistic regressions and computed predictive marginals were used to estimate age-adjusted percentages and 95 % confidence intervals (CI). A total of 11,320 eligible individuals (727 cancer survivors, 10,593 controls) were included. Respondents were primarily non-Hispanic White (95.3 % of survivors, 84.1 % of controls). Survivors were older (85 % of survivors ≥40 years of age vs. 47 % of controls). Survivors reported the majority of their cancer survivorship care was managed by primary care physicians or non-cancer specialists (93.5 %, 95 % CI = 87.9-99.1). Furthermore, 71.1 % (95 % CI = 59.2-82.9) of survivors reported that they did not receive a cancer treatment summary. In multivariable estimates, fair/poor general health was more common among survivors compared to controls (17.8 %, 95 % CI = 12.5-23.1 vs. 14.2 %, 95 % CI = 12.4-16.0). Few survivors in Utah receive follow-up care from a cancer specialist. Provider educational efforts are needed to promote knowledge of cancer survivor issues. Efforts should be made to improve continuity in follow-up care that addresses the known issues of long-term survivors that preclude optimal quality of life, resulting in a patient-centered approach to survivorship.

Abstract
PURPOSE The aim of this study was to determine risk for melanoma among individuals who have a first- or second-degree relative with a history of melanoma, based on the unaffected individual's age and age at diagnosis of the relative. METHODS The study employed a case-control design using a statewide database linked with a Surveillance Epidemiology and End Results cancer registry. A population-based sample of individuals who received at least one diagnosis of first primary, malignant melanoma (n = 14,281), as well as their first- and second-degree relatives, was included. Control individuals with no history of melanoma (n = 70,889) were matched to cases on birth year, gender, race/ethnicity, and county at birth. RESULTS Risk for melanoma among relatives of melanoma patients declined with relative's age and age at diagnosis. Individuals between ages 40 and 49 who are first-degree relatives of melanoma patients diagnosed between ages 40 and 49 had the greatest risk for melanoma compared with individuals without a first-degree relative with a melanoma history (HR 4.89; 95% CI 3.11-7.68). Increased melanoma risk among second-degree relatives of patients was typically lower than that for first-degree relatives. CONCLUSIONS Risk for melanoma, at earlier ages than expected, is increased among relatives of individuals with a history of melanoma, particularly if the melanoma case was diagnosed at a young age. Further research on the relationship between age at diagnosis and relative's melanoma risk could inform melanoma screening recommendations for individuals with a family history of the disease.

Abstract
Adherence to oral medications during maintenance therapy is essential for pediatric patients with acute lymphoblastic leukemia. Self-reported or electronic monitoring of adherence indicate suboptimal adherence, particularly among particular sociodemographic groups. This study used medication refill records to examine adherence among a national sample of pediatric patients with acute lymphoblastic leukemia. Patients in a national claims database, aged 0 to 21 years with a diagnosis of acute lymphoblastic leukemia and in the maintenance phase of treatment, were included. Medication possession ratios were used as measures of adherence. Overall adherence and adherence by sociodemographic groups were examined. Adherence rates were 85% for 6-mercaptopurine and 81% for methotrexate. Adherence was poorer among patients 12 years and older. Oral medication adherence rates were suboptimal and similar to or lower than previously documented rates using other methods of assessing adherence. Refill records offer a promising avenue for monitoring adherence. Additional work to identify groups most at-risk for poor adherence is needed. Nurses are well positioned to routinely monitor for medication adherence and to collaborate with the multidisciplinary team to address barriers to adherence.

Abstract
Predispositional genetic testing among minor children is intensely debated due to the potential benefits and harms of providing this type of genetic information to children and their families. Existing guidelines on pediatric genetic testing state that predispositional testing could be appropriate for minors if preventive services exist that mitigate children's risk for or severity of the health condition in question. We use the example of hereditary melanoma to illustrate the rationale for and potential application of genetic risk communication for an adult-onset cancer to a pediatric population where childhood behaviors may reduce risk of disease later in life. We draw from the adult melanoma genetic risk communication and pediatric health behavior change literatures to suggest ways in which genetic test reporting and complementary education could be delivered to children who carry a hereditary risk for melanoma and their families in order to foster children's engagement in melanoma preventive behaviors. Genetic discoveries will continue to yield new opportunities to provide predispositional genetic risk information to unaffected individuals, including children, and could be delivered within programs that provide personalized and translational approaches to cancer prevention.

Abstract
This study aimed to identify young adult Korean cancer survivors' individual- (psychological distress, stigma, sociodemographic variables, and cancer-related variables) and network-level factors (relationship type, social support type) that influence discussion of their cancer experiences. Sixty-eight survivors of childhood cancer who were recruited using snowball sampling nominated 245 individuals from their networks, including family and intimate partners (40%) and friends and acquaintances (60%), as people with whom they most frequently interacted. Results of multilevel modeling analysis indicated that higher levels of internalized shame were a prominent individual-level factor associated with a lack of discussion of cancer experiences. Relationship type and support type at the network-level were also significant correlates of discussion of cancer experiences. Programs for reducing the survivors' shame, improving illness identity, and providing professional training for building social relationships that are intimate and in which they could exchange reciprocal support may help Korean childhood cancer survivors to openly share their cancer experiences with others in their social network and to be successful in the journey of cancer survivorship.

Abstract
Background The number of Web-based psychological and behavioral interventions is growing. Beyond their theoretical underpinnings, a key factor to the success of these interventions is how they are designed and developed to ensure usability over a new method of delivery. Our team has adapted ecomapping, a tool for visualizing family caregiver social network resources, for the Web. Here, we describe how we designed and developed the electronic Social Network Assessment Program (eSNAP) Web-based tool using a framework of the Center for eHealth and Wellbeing Research (CeHRes) Roadmap for Web-based intervention development. The CeHRes Roadmap is still new in terms of tool development and we showcase an example of its application. Objective The aim of our study was to provide an example of the application of the Web-based intervention development process using the CeHRes Roadmap for other research teams to follow. In doing so, we are also sharing our pilot work to enhance eSNAP’s acceptance and usability for users and the feasibility of its implementation. Methods We describe the development of the eSNAP app to support family caregivers of neuro-oncology patients. This development is based on the 5 iterative stages of the CeHRes Roadmap: contextual inquiry, value specification, design, operationalization, and summative evaluation. Research activities to support eSNAP development prior to implementation included literature review, focus groups, and iterative rounds of interviews. Results Key lessons learned in developing the eSNAP app broadly fell under a theme of translating theoretical needs and ideas to the real world. This included how to prioritize needs to be addressed at one time, how the modality of delivery may change design requirements, and how to develop a tool to fit within the context it will be used. Conclusions Using the CeHRes Roadmap to develop Web-based interventions such as eSNAP helps to address potential issues by outlining important intervention development milestones. In addition, by encouraging inclusion of users and other stakeholders in the process, Web-based intervention developers using the Roadmap can identify what will work in the real world and increase feasibility and effectiveness.

Abstract
We show that a high-energy electron bunch can be used to capture the instantaneous longitudinal and transverse field structures of the highly transient, microscopic, laser-excited relativistic wake with femtosecond resolution. The spatiotemporal evolution of wakefields in a plasma density up ramp is measured and the reversal of the plasma wake, where the wake wavelength at a particular point in space increases until the wake disappears completely only to reappear at a later time but propagating in the opposite direction, is observed for the first time by using this new technique.

Abstract
Agro-ecosystems play an important role in regulating global changes caused by greenhouse gas emissions. Restoration of soil organic carbon (SOC) in agricultural soils can not only improve soil quality but also influence climate change and agronomic productivity. With about half of its land area under agricultural use, China exhibits vast potential for carbon (C) sequestration that needs to be researched. Chinese cropland has experienced SOC change over the past century. The study of SOC dynamics under different bioclimatic conditions and cropping systems can help us to better understand this historical change, current status, the impacts of bioclimatic conditions on SOC and future trends. We used a simulation based on historical statistical data to analyze the C balance of Chinese croplands during the 1980s and 1990s, taking into account soil, climate and agricultural management. Nationwide, 77.6% of the national arable land is considered to be in good condition. Appropriate farm management practices should be adopted to improve the poor C balance of the remaining 22.4% of cropland to promote C sequestration.

Abstract
Despite the highly preventable nature of skin cancer, it remains the most commonly diagnosed form of cancer in the United States. Recommendations for a complete skin cancer prevention regimen include engaging in photoprotection (e.g., sunscreen use), avoiding skin cancer risk behaviors (e.g., tanning), and receiving total body skin exams from a health care provider. The current study examined reported engagement in these behaviors among participants attending a community skin cancer screening (N = 319) in a high-risk catchment area to assess the need for increased health education on skin cancer prevention. Participants' responses indicate a history of suboptimal avoidance of skin cancer risk behaviors. Over half of participants (52%) reported four or more blistering sunburns before age 20, and 46% reported indoor tanning at least one during their lifetime. There is a need among this population for education regarding a complete skin cancer prevention regimen, which could improve adherence to photoprotection and avoidance of skin cancer risk behaviors, thereby reducing morbidity and mortality due to skin cancer.

Abstract
The transverse stability of the target is crucial for obtaining high quality ion beams using the laser radiation pressure acceleration (RPA) mechanism. In this Letter, a theoretical model and supporting two-dimensional (2D) particle-in-cell (PIC) simulations are presented to clarify the physical mechanism of the transverse instability observed in the RPA process. It is shown that the density ripples of the target foil are mainly induced by the coupling between the transverse oscillating electrons and the quasistatic ions, a mechanism similar to the oscillating two stream instability in the inertial confinement fusion research. The predictions of the mode structure and the growth rates from the theory agree well with the results obtained from the PIC simulations in various regimes, indicating the model contains the essence of the underlying physics of the transverse breakup of the target.

Abstract
PURPOSE To explore adolescent and young adult (AYA) cancer survivors' internet use in seeking healthy lifestyle behavior (HLB) information on diet and exercise. METHODS Twenty-five AYA cancer survivors participated in focus groups or interviews. Data were analyzed using qualitative content analysis. RESULTS Most survivors (92%) sought HLB information from internet sources. Key issues included the following: (1) too much information available, (2) information not meeting survivors' unique needs, and (3) concerns about trustworthiness of information. CONCLUSION Although AYA cancer survivors use the internet to seek HLB information, internet resources could be modified to better meet the needs of AYA cancer survivors.
