RESUMO

BACKGROUND/OBJECTIVES: Despite the pervasiveness of late effects in childhood cancer survivors, many parents feel inadequately informed about their child's risks. We assessed early parental knowledge of risks of late effects and predictors of increased knowledge. DESIGN/METHODS: Parents of children receiving cancer treatment at Dana-Farber/Boston Children's Cancer and Blood Disorders Center were surveyed about their knowledge of their child's likelihood of eight late effects. Individual risk for each late effect (yes/no) was assessed using the Children's Oncology Group's Long-Term Follow-Up Guidelines v5 as a reference. Descriptive statistics were used to summarize knowledge scores; ordinal logistic regression was used to identify predictors of higher knowledge. RESULTS: Of 96 parent participants, 11 (11.46%) correctly identified all of their child's risks for the eight late effects. Five of eight was the median number of correctly identified late effect risks. Among 21 parents whose children were at risk for ototoxicity, 95% correctly identified this risk. Conversely, parents of at-risk children were less knowledgeable about risks of secondary malignancy (63% correct identification, of N = 94 at risk), cardiac toxicity (61%; N = 71), neurocognitive impairment (56%; N = 63), and infertility (28%; N = 61). Ordinal logistic regression analysis identified no significant differences in parental knowledge of late effect risks by any factors evaluated. CONCLUSIONS: Gaps in parental knowledge of potential late effects of childhood cancer treatment emerge early in a child's care, and parents are more knowledgeable about some late effects, such as ototoxicity, than others, such as infertility. As no child- or parent-specific factors were associated with increased knowledge of late effect risks, interventions must be applied broadly.

RESUMO

BACKGROUND: Thyroid function abnormalities can occur after treatment for childhood cancer. Evidence for the management of thyroid dysfunction among asymptomatic childhood cancer survivors (CCS) is lacking. We used a Delphi consensus methodology to expand guidelines for screening asymptomatic CCS at risk for thyroid dysfunction and explore recommendations for the clinical management of abnormal results. PROCEDURE: A Delphi panel of 40 expert physicians representing oncology, endocrinology, and primary care participated in three rounds of anonymous, iterative questionnaires formatted as clinical scenarios. Consensus is defined as ≥ 90% of panelists agree with recommendation and disagreement as < 70% agree. RESULTS: Panelists reached consensus that CCS treated with radiation including neck, total body, whole brain, brain including the hypothalamic-pituitary axis (HPA), and therapeutic meta-iodobenzylguanidine (MIBG) should have annual, lifelong screening using serum thyroid-stimulating hormone (TSH) and free T4 starting within one year off-treatment (98%). Panelists disagreed on continuing to screen CCS for thyroid dysfunction after immunotherapy associated with acute thyroid injury (31%-50%). There was also disagreement on indications for brain (17%-43%) or thyroid (50%-65%) imaging, laboratory tests to assess the HPA (29%-75%), and TSH threshold to initiate treatment of subclinical hypothyroidism. Lack of evidence was the most frequent rationale panelists offered for not recommending additional testing or medications. Panelists' recommendations did not vary by geography, specialty, or survivorship clinical experience. CONCLUSIONS: Consensus was reached on most recommendations for screening and management of cancer treatment-related thyroid dysfunction. Screening after completion of thyroid-toxic immunotherapy, indications for imaging, and treatment of subclinical hypothyroidism are areas of disagreement for further investigation.

RESUMO

Female patients with childhood, adolescent, and young adult cancer are at increased risk for fertility impairment when treatment adversely affects the function of reproductive organs. Patients and their families desire biological children but substantial variations in clinical practice guidelines reduce consistent and timely implementation of effective interventions for fertility preservation across institutions. As part of the PanCareLIFE Consortium, and in collaboration with the International Late Effects of Childhood Cancer Guideline Harmonization Group, we reviewed the current literature and developed a clinical practice guideline for fertility preservation in female patients who were diagnosed with childhood, adolescent, and young adult cancer at age 25 years or younger, including guidance on risk assessment and available methods for fertility preservation. The Grading of Recommendations Assessment, Development and Evaluation methodology was used to grade the available evidence and to form the recommendations. This clinical practice guideline leverages existing evidence and international expertise to develop transparent recommendations that are easy to use to facilitate the care of female patients with childhood, adolescent, and young adult cancer who are at high risk for fertility impairment. A complete review of the existing evidence, including a quality assessment, transparent reporting of the guideline panel's decisions, and achievement of global interdisciplinary consensus, is an important result of this intensive collaboration.

RESUMO

Male patients with childhood, adolescent, and young adult cancer are at an increased risk for infertility if their treatment adversely affects reproductive organ function. Future fertility is a primary concern of patients and their families. Variations in clinical practice are barriers to the timely implementation of interventions that preserve fertility. As part of the PanCareLIFE Consortium, in collaboration with the International Late Effects of Childhood Cancer Guideline Harmonization Group, we reviewed the current literature and developed a clinical practice guideline for fertility preservation in male patients who are diagnosed with childhood, adolescent, and young adult cancer at age 25 years or younger, including guidance on risk assessment and available methods for fertility preservation. The Grading of Recommendations Assessment, Development and Evaluation methodology was used to grade the available evidence and to form the recommendations. Recognising the need for global consensus, this clinical practice guideline used existing evidence and international expertise to rigorously develop transparent recommendations that are easy to use to facilitate the care of male patients with childhood, adolescent, and young adult cancer who are at high risk of fertility impairment and to enhance their quality of life.

RESUMO

Patients with childhood, adolescent, and young adult cancer who will be treated with gonadotoxic therapies are at increased risk for infertility. Many patients and their families desire biological children but effective communication about treatment-related infertility risk and procedures for fertility preservation does not always happen. The PanCareLIFE Consortium and the International Late Effects of Childhood Cancer Guideline Harmonization Group reviewed the literature and developed a clinical practice guideline that provides recommendations for ongoing communication methods for fertility preservation for patients who were diagnosed with childhood, adolescent, and young adult cancer at age 25 years or younger and their families. Moreover, the guideline panel formulated considerations of the ethical implications that are associated with these procedures. Grading of Recommendations Assessment, Development and Evaluation methodology was used to grade the evidence and recommendations. In this clinical practice guideline, existing evidence and international expertise are combined to develop transparent recommendations that are easy to use to facilitate ongoing communication between health-care providers and patients with childhood, adolescent, and young adult cancer who might be at high risk for fertility impairment and their families.

RESUMO

Telemedicine can potentially meet objectives of long-term follow-up care (LTFU) for childhood cancer survivors (CCS) while reducing barriers. We surveyed providers at our institution about their satisfaction with video-conference virtual visits (VV) with 81 CCS during COVID-19 restrictions. The same 81 CCS (or parent proxies) were surveyed about their experience, of which 47% responded. Providers and CCS were highly satisfied with VV (86% and 95% "completely/very satisfied," respectively). CCS rated VV "as/nearly as" helpful as in-person visits (66%) and 82% prefer VV remain an option postpandemic. High levels of survivor and provider satisfaction with VV support ongoing investigation into implementation for LTFU.

RESUMO

BACKGROUND: Treatment-associated cardiomyopathy is a leading cause of morbidity and mortality for childhood cancer survivors (CCS). As evidence is not available to guide the management of CCS at risk for cardiomyopathy, we aim to describe the collective opinion of regional experts for the care of these patients using a consensus-based Delphi methodology. PROCEDURE: Nineteen physicians from the New England region who care for CCS treated with cardiotoxic therapy (anthracyclines, thoracic radiation) participated in a Delphi panel querying their management approach, using three rounds of anonymous questionnaires formatted as five clinical scenarios. Consensus ≥ 89% agreement. RESULTS: The response rate was 100% for the first round and 95% for subsequent rounds. Panelists reached consensus on screening asymptomatic CCS with serial echocardiograms (94%) and electrocardiograms (89%), with some disagreement on frequency during pregnancy (83%). All panelists agreed with exercise promotion, with no restrictions on weight training. Consensus was reached on indications for referrals; cardiology for asymptomatic left ventricular dysfunction (ALVD) (100%) and maternal-fetal medicine for pregnancy (94%). In the scenario of ALVD, there was disagreement on the benefit of additional cardiac testing (50% cardiologists recommended cardiac MRI), and although all panelists endorsed treating with angiotension-converting enzyme (ACE) inhibitors, most adult cardiologists (75%) also recommended therapy with beta blockers, compared with none of the pediatric cardiologists or primary-care physicians. CONCLUSIONS: Despite a lack of evidence to guide the management of CCS at risk for cardiomyopathy, a panel of regional physicians reached consensus on managing most clinical scenarios. A controversial area requiring further study is the medical management of ALVD.

RESUMO

BACKGROUND: Sexual and reproductive health (SRH) is identified by adolescent and young adult (AYA) patients with cancer as an important but often neglected aspect of their comprehensive cancer care. The purpose of this study was to investigate the attitudes and perceptions of pediatric oncology clinicians towards discussing SRH with AYAs, and to understand perceived barriers to effective communication in current practice. PROCEDURE: Pediatric oncology clinicians (physicians, certified nurse practitioners, and physician assistants) participated in semi-structured qualitative interviews investigating attitudes about SRH communication with AYAs and barriers to such conversations. Twenty-two clinicians participated from seven institutions in the Northeastern United States. Interviews were audio-recorded, transcribed, and coded using a thematic analysis approach. RESULTS: Interviews with pediatric oncology clinicians revealed the following five primary themes: the role for pediatric oncology clinicians to discuss SRH, the focus of current SRH conversations on fertility, the meaning of "sexual health" as safe sex and contraception only, clinician-reported barriers to SRH conversations, and the need for education and support. Communication barriers included lack of knowledge/experience, lack of resources/referrals, low priority, parents/family, patient discomfort, clinician discomfort, time, and lack of rapport. Clinicians identified resource and support needs, including formal education and SRH education materials for patients and families. CONCLUSIONS: Although the study participants identified a role for pediatric oncology clinicians in SRH care for AYA patients with cancer, multiple barriers interfere with such discussions taking place on a regular basis. Future efforts must focus on resource development and provider education and training in SRH to optimize the care provided to this unique patient population.

RESUMO

BACKGROUND: Evidence is not available to guide management of childhood cancer survivors (CCS) at risk for radiation-associated cerebral vascular disease (CVD) and stroke. We propose to use a consensus-based methodology to describe the collective opinion of regional experts for the care of these patients and identify areas of controversy. PROCEDURE: Thirty physicians from the New England region who care for CCS participated in a Delphi panel querying their management approach (imaging, laboratory tests, medications, counseling, referrals) to a CCS treated with cranial radiation formatted as five clinical scenarios (asymptomatic, small- and large-vessel CVD, transient ischemia, stroke) in three rounds of anonymous questionnaires. Consensus defined as ≥90% agreement. RESULTS: Response rate was 100% for all three rounds. Panelists reached consensus on laboratory tests to assess stroke risk factors, stroke risk and prevention counseling, brain imaging to monitor survivors with known CVD, and acute care for stroke symptoms. Only 67% panelists agreed with MRI screening asymptomatic survivors with no history of CVD, 87% endorsed aspirin as stroke prevention for large-vessel CVD and 57% for small-vessel CVD. There was no consensus on specialty referrals. Overall, panelists practicing at large institutions and neurology subspecialists were more likely to advocate for screening, interventions, and referrals. CONCLUSIONS: Despite lack of evidence to guide stroke prevention in CCS treated with cranial radiation, a panel of regional physicians reached consensus on managing most clinical scenarios. Controversial areas requiring further study are surveillance imaging for asymptomatic survivors, aspirin for stroke prevention, and indications for specialty referral.

RESUMO

Treatment with chemotherapy, radiotherapy, or surgery that involves reproductive organs can cause impaired spermatogenesis, testosterone deficiency, and physical sexual dysfunction in male pubertal, adolescent, and young adult cancer survivors. Guidelines for surveillance and management of potential adverse effects could improve cancer survivors' health and quality of life. Surveillance recommendations vary considerably, causing uncertainty about optimum screening practices. This clinical practice guideline recommended by the International Late Effects of Childhood Cancer Guideline Harmonization Group in collaboration with the PanCareSurFup Consortium, developed using evidence-based methodology, critically synthesises surveillance recommendations for gonadotoxicity in male childhood, adolescent, and young adult (CAYA) cancer survivors. The recommendations were developed by an international multidisciplinary panel including 25 experts in relevant medical specialties, using a consistent and transparent process. Recommendations were graded according to the strength of underlying evidence and potential benefit gained by early detection and appropriate management. The aim of the recommendations is to enhance evidence-based care for male CAYA cancer survivors. The guidelines reveal the paucity of high-quality evidence, highlighting the need for further targeted research.

RESUMO

BACKGROUND: Childhood cancer survivors (CCSs) remain at risk for developing treatment-associated health conditions as they age; however, many do not obtain recommended follow-up, putting them at unnecessary risk for morbidity. Educational interventions targeted at providing survivors with the knowledge and skills necessary for healthcare independence might improve adherence and outcomes as they transition care to the adult medical system. OBJECTIVE: To identify informational needs, educational preferences, and support that young adult CCSs perceive as beneficial for transition from pediatric to adult medical care. DESIGN/METHOD: Sixteen young adult CCSs (ages 22-39 years) who have transitioned to adult care participated in focus groups led by a trained moderator and analyzed using a thematic analysis approach. RESULTS: Four major themes emerged: (1) education preferences-pediatric oncology provider as the primary source of information and guidance, enhanced by other formats, and early and ongoing engagement in education; (2) family role in transition-desire for independence and acknowledgement of need for ongoing parental support; (3) expectations for adult providers, such as close relationships, open communication, and care coordination; and (4) knowledge deficits regarding disease/treatment history, risk for long-term complications, and navigation of the adult medical system. CONCLUSION: Transition education as described by young adult CCSs should be a developmentally appropriate process beginning in early adolescents, primarily administered by pediatric oncology providers, and delivered in multiple formats. While healthcare independence is a goal for young adult CCSs, all stakeholders must recognize that families and providers continue to have an important role supporting survivors with transition logistics and medical decision-making.

RESUMO

BACKGROUND: Pediatric oncologists are responsible for ensuring that adolescent and young adult (AYA) childhood cancer survivors have the knowledge and skills necessary to manage their follow-up care in adult healthcare systems. PROCEDURES: To describe transition practices and barriers to transfer, we electronically surveyed U.S. Children's Oncology Group members: 507/1449 responded (35%) and 347/507 (68%) met eligibility criteria. RESULTS: Of 347 respondents, 50% are male, median years in practice 10 (range 5-22), 37% practice in freestanding children's hospitals. Almost all care for survivors up to age 21 years (96%), 42% care for survivors over age 25 years, and only 16% over age 30 years. While 66% of oncologists reported providing transition education to their patients, very few (8%) reported using standardized transition assessments. The most frequent barriers to transfer were perceived attachment to provider (91%), lack of adult providers with cancer survivor expertise (86%), patient's cognitive delay (81%), or unstable social situation (80%). Oncologists who continue to care for patients older than 25 years are more likely to perceive parents' attachment to provider (P = 0.037) and patients' social situation as barriers to transfer (P = 0.044).  Four themes emerged from a content analysis of 75 respondents to the open-ended question inviting comments on transition/transfer practices: desire for flexible transfer criteria; providers as barriers; provider lack of transition knowledge, skills, and resources; and desire for collaboration. CONCLUSIONS: Although most pediatric oncologists reported transferring AYA cancer survivors to adult care and providing some transition education, they endorse deficits in transition skills, emotional readiness, and institutional resources.

RESUMO

BACKGROUND: Many survivors of childhood cancer do not receive recommended longitudinal oncology care. Factors present at the time of childhood cancer diagnosis may identify patients who are vulnerable to poor adherence to follow-up. METHODS: This cohort of survivors of acute lymphoblastic leukemia (ALL) diagnosed from 1996 to 1999 at seven Consortium for New England Childhood Cancer Survivors institutions was evaluated for attendance at oncology clinics at 5 and 10 years from diagnosis. Demographic, socioeconomic, disease, and treatment characteristics were analyzed as risk factors for nonadherence to follow-up. RESULTS: Of 317 patients, 90% were alive 5 years from diagnosis and 88% of those remained in active follow-up. At 10 years from diagnosis, 88% were alive, 73% of whom continued in active follow-up. Insurance status at diagnosis was significantly associated with adherence at both 5 and 10 years. At 10 years, initial enrollment on therapeutic study was associated with increased attendance and central nervous system (CNS) leukemia with decreased attendance. In multivariable modeling of follow-up at 5 years, patients who were adults were less likely to participate and those with private insurance at diagnosis more likely to participate. At 10 years, insurance status at diagnosis remained a predictor of adherence to follow-up. CONCLUSIONS: In this regional cohort, many patients who are survivors of ALL continue to participate in oncology care at 5 and 10 years from diagnosis. Factors known at diagnosis including insurance status, CNS leukemia, older age, and enrollment on therapeutic study were associated with differential attendance to follow-up visits.

RESUMO

BACKGROUND: The effect of many contemporary chemotherapeutic drugs on pregnancy and livebirth is not well established. We aimed to establish the effects of these drugs on pregnancy in male and female survivors of childhood cancer not exposed to pelvic or cranial radiotherapy. METHODS: We used data from a subset of the Childhood Cancer Survivor Study cohort, which followed 5-year survivors of the most common types of childhood cancer who were diagnosed before age 21 years and treated at 27 institutions in the USA and Canada between 1970 and 1999. We extracted doses of 14 alkylating and similar DNA interstrand crosslinking drugs from medical records. We used sex-specific Cox models to establish the independent effects of each drug and the cumulative cyclophosphamide equivalent dose of all drugs in relation to pregnancies and livebirths occurring between ages 15 years and 44 years. We included siblings of survivors as a comparison group. FINDINGS: We included 10 938 survivors and 3949 siblings. After a median follow-up of 8 years (IQR 4-12) from cohort entry or at age 15 years, whichever was later, 4149 (38%) survivors reported having or siring a pregnancy, of whom 3453 (83%) individuals reported at least one livebirth. After a median follow-up of 10 years (IQR 6-15), 2445 (62%) siblings reported having or siring a pregnancy, of whom 2201 (90%) individuals reported at least one livebirth. In multivariable analysis, survivors had a decreased likelihood of siring or having a pregnancy versus siblings (male survivors: hazard ratio [HR] 0·63, 95% CI 0·58-0·68; p<0·0001; female survivors: 0·87, 0·81-0·94; p<0·0001) or of having a livebirth (male survivors: 0·63, 0·58-0·69; p<0·0001; female survivors: 0·82, 0·76-0·89; p<0·0001). In male survivors, reduced likelihood of pregnancy was associated with upper tertile doses of cyclophosphamide (HR 0·60, 95% CI 0·51-0·71; p<0·0001), ifosfamide (0·42, 0·23-0·79; p=0·0069), procarbazine (0·30, 0·20-0·46; p<0·0001) and cisplatin (0·56, 0·39-0·82; p=0·0023). Cyclophosphamide equivalent dose in male survivors was significantly associated with a decreased likelihood of siring a pregnancy (per 5000 mg/m(2) increments: HR 0·82, 95% CI 0·79-0·86; p<0·0001). However, in female survivors, only busulfan (<450 mg/m(2) HR 0·22, 95% CI 0·06-0·79; p=0·020; ≥450 mg/m(2) 0·14, 0·03-0·55; p=0·0051) and doses of lomustine equal to or greater than 411 mg/m(2) (0·41, 0·17-0·98; p=0·046) were significantly associated with reduced pregnancy; cyclophosphamide equivalent dose was associated with risk only at the highest doses in analyses categorised by quartile (upper quartile vs no exposure: HR 0·85, 95% CI 0·74-0·98; p=0·023). Results for livebirth were similar to those for pregnancy. INTERPRETATION: Greater doses of contemporary alkylating drugs and cisplatin were associated with a decreased likelihood of siring a pregnancy in male survivors of childhood cancer. However, our findings should provide reassurance to most female survivors treated with chemotherapy without radiotherapy to the pelvis or brain, given that chemotherapy-specific effects on pregnancy were generally few. Nevertheless, consideration of fertility preservation before cancer treatment remains important to maximise the reproductive potential of all adolescents newly diagnosed with cancer.

RESUMO

BACKGROUND: Fertility preservation care for children, adolescents, and young adults (CAYAs) with cancer is not uniform among practitioners. To ensure high-quality care, evidence-based clinical practice guidelines (CPGs) are essential. The authors identified existing CPGs for fertility preservation in CAYAs with cancer, evaluated their quality, and explored differences in recommendations. METHODS: A systematic search in PubMed (January 2000-October 2014); guideline databases; and Web sites of oncology, pediatric, and fertility organizations was performed. Two reviewers evaluated the quality of the identified CPGs using the Appraisal of Guidelines for Research and Evaluation II Instrument (AGREE II). From high-quality CPGs, the authors evaluated concordant and discordant areas among the recommendations. RESULTS: A total of 25 CPGs regarding fertility preservation were identified. The average AGREE II domain scores (scale of 0%-100%) varied from 15% on applicability to 100% on clarity of presentation. The authors considered 8 CPGs (32%) to be of high quality, which was defined as scores ≥60% in any 4 domains. Large variations in the recommendations of the high-quality CPGs were observed, with 87.2% and 88.6%, respectively, of discordant guideline areas among the fertility preservation recommendations for female and male patients with cancer. CONCLUSIONS: Only approximately one-third of the identified CPGs were found to be of sufficient quality. Of these CPGs, the fertility preservation recommendations varied substantially, which can be a reflection of inadequate evidence for specific recommendations, thereby hindering the ability of providers to deliver high-quality care. CPGs including a transparent decision process for fertility preservation can help health care providers to deliver optimal and uniform care, thus improving the quality of life of CAYAs with cancer and cancer survivors.

RESUMO

To assess testicular function after standard dose ifosfamide, we evaluated 6 young adult osteosarcoma survivors (median age at diagnosis, 16.5 y; median follow-up, 4 y) treated with ifosfamide (median dose, 45.5 g/m) as part of a chemotherapy regimen (adriamycin/cisplatin/methotrexate/ifosfamide/± muramyl-tripeptide-phosphatidyl-ethanolamine). Four of 6 survivors (67%) had abnormal semen analysis (2 oligospermic, 2 azoospermic). Of those, 1/4 had reduced testicular volume, and 2/3 elevated FSH levels. All reported adequate sexual function, 6/6 had normal testosterone levels, but 4/6 had elevated LH levels. Ifosfamide exposure in the context of this regimen was associated with a high likelihood of impaired spermatogenesis and Leydig cell insufficiency.

RESUMO

PURPOSE: We sought to present the current status of survivorship programs at Dana-Farber Cancer Institute which include the David B. Perini, Jr. Quality of Life Clinic for survivors of childhood cancer, Stop and Shop Neuro-Oncology Outcomes Clinic for pediatric brain tumor survivors, and Adult Survivorship Program for adult cancer survivors including those diagnosed as adults (age 18 years and older) and adult survivors of childhood cancer, in an effort to share best practices as well as challenges. METHODS: Description of programs and discussion. RESULTS: Our institutional programs are detailed regarding their history and the multidisciplinary approach and both consultative and long-term care delivery models for pediatric and adult cancer survivors, with the goal of meeting the spectrum of survivorship care needs, from diagnosis and management of long-term effects of cancer-directed therapy and surveillance for subsequent cancer, to healthy lifestyle promotion and psychosocial support. Program investigators conduct research to understand the risks and unmet needs of cancer survivors, and to develop and test interventions to improve care delivery and medical and psychosocial outcomes. There are also educational initiatives detailed. CONCLUSIONS: Survivorship programs at Dana-Farber are designed to optimize care and outcomes for cancer survivors including conducting quality improvement initiatives and research to further understand and meet the clinical needs of the large, heterogenous, and growing population cancer survivors into the future. IMPLICATIONS FOR CANCER SURVIVORS: Programs like ours as well as those ongoing and planned aim to improve the comprehensive care of diverse cancer survivors.

RESUMO

INTRODUCTION: Of the approximately 12,000 children and adolescents that will be diagnosed with cancer in 2013, it is expected that over 80% of them will become long-term adult survivors of childhood cancer. Although it has been well established that cancer treatment often has profound negative impact on sexual functioning, sexual functioning in adult survivors of childhood cancer is not well understood. AIM: The aim of the current study was to examine the report of sexual function in adult survivors of childhood cancer in relationship to both physical and emotional functioning. METHODS: Two hundred ninety-one participants enrolled in Project REACH, a longitudinal study of childhood cancer survivors, completed questionnaires as part of an annual health survey. MAIN OUTCOME MEASURE: Primary outcome measures included the sexual functioning subscale of the Swedish Health-Related Quality of Life Survey, the SF-12, and the BSI-18. RESULTS: Results indicate that 29% of young adult survivors reported two or more discrete symptoms of sexual dysfunction. Females were twice as likely to report sexual problems. Sexual problems were not related to specific types of childhood cancer treatments such as type of chemotherapy or radiation. Young adults with sexual dysfunction did report poorer functioning across the range of SF-12 subscales including physical functioning, general health, fatigue, and mental health. CONCLUSIONS: Significant sexual dysfunction is common in adult survivors of childhood cancer. A greater understanding of the particular relationship between sexual dysfunction and both physical and emotional well-being in this relatively young population is needed. Even when long-term cancer survivors are young adults and report generally good health, results underscore the need for clinicians to specifically assess sexual functioning.

RESUMO

Background: Cardiomyopathy is a leading cause of late morbidity and mortality in childhood cancer survivors (CCS). Evidence-based guidelines recommend risk-stratified screening for cardiomyopathy, but the management approach for abnormalities detected when screening asymptomatic young adult CCS is poorly defined. Objectives: The aims of this study were to build upon existing guidelines by describing the expert consensus-based cardiomyopathy screening practices, management approach, and clinical rationale for the management of young adult CCS with screening-detected abnormalities and to identify areas of controversy in practice. Methods: A multispecialty Delphi panel of 40 physicians with expertise in cancer survivorship completed 3 iterative rounds of semi-open-ended questionnaires regarding their approaches to the management of asymptomatic young adult CCS at risk for cardiomyopathy (screening practices, referrals, cardiac testing, laboratory studies, medications). Consensus was defined as ≥90% panelist agreement with recommendation. Results: The response rate was 100% for all 3 rounds. Panelists reached consensus on the timing and frequency of echocardiographic screening for anthracycline-associated cardiomyopathy, monitoring during pregnancy, laboratory testing for modifiable cardiac risk factors, and referral to cardiology for ejection fraction ≤50% or preserved ejection fraction with diastolic dysfunction. Controversial areas (<75% agreement) included chest radiation dose threshold to merit screening, indications for advanced cardiac imaging and cardiac serum biomarkers for follow-up of abnormal echocardiographic findings, and medical management of asymptomatic left ventricular systolic dysfunction. Conclusions: Expert practice is largely consistent with existing risk-based screening guidelines. Some recommendations for managing abnormalities detected on screening echocardiography remain controversial. The rationale offered by experts for divergent approaches may help guide clinical decisions in the absence of guidelines specific to young adult CCS.

RESUMO

BACKGROUND AND OBJECTIVES: There is insufficient evidence to support stroke prevention guidelines for childhood cancer survivors (CCS) treated with cranial irradiation for CNS tumors or other childhood cancers involving the CNS. We used a systematic consensus-building methodology to develop expert recommendations and define areas of controversy in managing asymptomatic CCS at risk for stroke. METHODS: A Delphi process was used to query a multispecialty panel of 45 physicians from the United States/Canada, with expertise in CCS, about their stroke screening and management practices (imaging, referrals, laboratory testing, and medications). Three iterative rounds of anonymous, scenario-based questionnaires, building on panelists' aggregate responses, were used to reach consensus (≥90% agreement), agreement (89%-70% agree), or to understand the rationale for disagreement (<70% agree). RESULTS: All 45 physicians participated in the first 2 rounds and 44 in the third. Panelists reached consensus on indications for referral to neurology and laboratory screening for modifiable cerebral vascular disease (CVD) risk factors in most scenarios. Panelists agreed that aspirin therapy is not recommended in the scenario of normal neuroimaging (86% agreed). Decisions about aspirin therapy in scenarios with abnormal neuroimaging were deferred to specialists; almost all agreed with not using aspirin for cavernomas with no evidence for previous hemorrhage (93%) and using aspirin for both large vessel CVD (93%) and small vessel CVD with evidence of previous stroke (86%). Clinical decisions that remain controversial (less than 70% agreement) include neuroimaging to screen asymptomatic CCS for CVD, referral to neurology for cavernomas, aspirin use in the setting of cavernomas with previous hemorrhage, or with evidence for small vessel CVD and no previous stroke, and indications for statins. Overall, pediatric neurologists/neuro-oncologists and radiation oncologists were more likely to advocate for screening and interventions. DISCUSSION: Despite lack of evidence to guide the management of CCS at risk for stroke, expert recommendations and rationale developed by consensus methodology are helpful to support clinical decision-making.
