Differences in palliative opportunities across diagnosis groups in children with cancer.

BACKGROUND: Childhood cancer causes significant physical and emotional stress. Patients and families benefit from palliative care (PC) to reduce symptom burden, improve quality of life, and enhance family-centered care. We evaluated palliative opportunities across leukemia/lymphoma (LL), solid tumors (ST), and central nervous system (CNS) tumor groups. PROCEDURE: A priori, nine palliative opportunities were defined: disease progression/relapse, hematopoietic stem cell transplant, phase 1 trial enrollment, admission for severe symptoms, social concerns or end-of-life (EOL) care, intensive care admission, do-not-resuscitate (DNR) status, and hospice enrollment. A single-center retrospective review was completed on 0-18-year olds with cancer who died from January 1, 2012 to November 30, 2017. Demographic, disease, and treatment data were collected. Descriptive statistics were performed. Opportunities were evaluated from diagnosis to death and across disease groups. RESULTS: Included patients (n = 296) had LL (n = 87), ST (n = 114), or CNS tumors (n = 95). Palliative opportunities were more frequent in patients with ST (median 8) and CNS tumors (median 7) versus LL (median 5, p = .0005). While patients with ST had more progression/relapse opportunities (p < .0001), patients with CNS tumors had more EOL opportunities (p < .0001), earlier PC consultation, DNR status, and hospice enrollment. Palliative opportunities increased toward the EOL in all diseases (p < .0001). PC was consulted in 108 (36%) patients: LL (48%), ST (30%), and CNS (34%, p = .02). CONCLUSIONS: All children with cancer incur many events warranting PC support. Patients with ST and CNS tumors had more palliative opportunities than LL, yet received less subspecialty PC. Understanding palliative opportunities within each disease group can guide PC utilization to ease patient and family stress.

Influenza Vaccination Receipt in Pediatric Patients With Cancer or Sickle Cell Disease.

BACKGROUND: Influenza causes greater morbidity in children with cancer or sickle cell disease (SCD). Literature on influenza vaccination receipt for these populations is limited in low-vaccination states. Outpatient interventions improve vaccine receipt but isolated inpatient interventions remain unstudied. PROCEDURE: We reviewed influenza vaccine receipt of children with cancer or SCD treated at Children's Healthcare of Atlanta during three influenza seasons. We implemented a clinical decision support intervention during an influenza season and compared influenza vaccine receipt preintervention and postintervention among admitted children. RESULTS: The oncology cohort (N=1548, 60% to 62%) and the SCD cohort (N=2549, 61% to 65%) had similar-to-higher vaccination receipt to the United States (58% to 64%, P =0.01 to 0.79) and Georgia (51% to 56%, P <0.01). The intervention did not significantly improve vaccination receipt for admitted children with cancer (40% vs. 56%, P =0.05 to 0.88) or SCD (44% vs. 56%, P =0.01). Regression modeling also found no significant increase in vaccine receipt (hematologic malignancy: 0.8 [0.73 to 0.98], solid tumor: 0.9 [0.80 to 1.90], central nervous system tumor: 0.9 [0.71 to 1.14], SCD: 0.9 [0.85 to 0.99]). CONCLUSIONS: Children with cancer and SCD have similar-to-greater influenza vaccination receipt compared with Georgia and the United States. An inpatient intervention did not significantly improve influenza vaccine receipt in these patient cohorts. Future studies are needed to identify alternative approaches to improving vaccine receipt in these cohorts.

Relationship of race and ethnicity on access, timing, and disparities in pediatric palliative care for children with cancer.

PURPOSE: Pediatric palliative care (PPC) improves quality of life for children and adolescents with cancer. Little is known about disparities between different racial and ethnic groups in the frequency and timing of PPC referrals. We evaluated the impact of race and ethnicity on the frequency and timing of PPC referral after initiation of an embedded PPO clinic where no formal consultation triggers exist. METHODS: Patients with cancer between 0 and 25 years at diagnosis who experienced a high-risk event between July 2015 and June 2018 were eligible. Demographic, disease, and PPC information were obtained. Descriptive statistics and logistic regression were used to assess likelihood of receiving PPC services by race/ethnicity. RESULTS: Of 426 patients who experienced a high-risk event, 48% were non-Hispanic White, 31% were non-Hispanic Black, 15% were Hispanic of any race, and 4% were non-Hispanic Asian. No significant differences were found between race/ethnicity and age at diagnosis/death, sex, and diagnosis. PPC consultation (p = 0.03) differed by race. Non-Hispanic Black patients were 1.7 times more likely than non-Hispanic White patients to receive PPC after adjustment (p = 0.01). White patients spent less days in the hospital in the last 90 days of life (3.0 days) compared with Black (8.0), Asian (12.5), or Hispanic patients (14.0, p = 0.009) CONCLUSION: Disparities exist in patients receiving pediatric oncology and PPC services. Cultural tendencies as well as unconscious and cultural biases may affect PPC referral by race and ethnicity. Better understanding of cultural tendencies and biases may improve end-of-life outcomes for children and young adults with cancer.

Using formative evaluation to plan for electronic psychosocial screening in pediatric oncology.

OBJECTIVE: To demonstrate how formative research methods can be used to plan for implementation of evidence-based psychosocial screening in pediatric oncology. METHODS: Multidisciplinary pediatric oncology professionals participated in focus groups to adapt the distress thermometer for electronic administration and develop health systems processes to promote psychosocial screening in the pediatric oncology outpatient clinic setting. Seven 1-hour focus groups were conducted using a structured guide based on the reach, efficacy, adoption, implementation, and maintenance framework and transcribed verbatim. Two independent raters coded transcripts using a quasi-deductive approach with high inter-coder reliability (Cohen kappa >0.80). RESULTS: Participants' (N = 44) responses were used to identify overarching topics related to the adoption, implementation, and maintenance of electronic screening (e-screening) including: barriers to meeting families' psychosocial needs, identification of champions, suggestions to adapt the proposed e-screening program, perceived barriers to e-screening, and potential impact of carrying out e-screening. Following review of qualitative data, we employed specific implementation strategies to promote adoption, implementation, and maintenance of an e-screening program. CONCLUSIONS: Perceived barriers to the implementation of psychosocial screening remain substantial, yet enthusiasm for using electronic health records (EHRs) technology to help meet patient needs through regular assessment was evident among pediatric oncology professionals. Electronic administration of screening and integration of results into the EHR in real time were identified as critical needs to overcome barriers to e-screening. Formative research including qualitative data from stakeholders can be used to tailor implementation strategies to successfully support the adoption, implementation, and maintenance of e-screening programs in pediatric oncology.

Palliative care considerations and practices for adolescents and young adults with cancer.

The definition of adolescents and young adults (AYAs) in oncology varies with upper limits up to age 39. Younger AYAs, ages 12-24 years, are often cared for within pediatrics. In caring for AYAs with cancer, there are unique considerations that become even more important to recognize, acknowledge, and address in AYAs with life-threatening cancer receiving palliative care. This review highlights important factors such as psychosocial development, cultural considerations, and support structure, which should be considered when providing palliative care to AYAs with cancer during the various stages of care: introduction of palliative care; symptom management; advanced care planning (ACP); end-of-life (EOL) care; and bereavement.

Features Associated With Weight Loss and Growth Stunting for Young Children During Cancer Therapy.

Features associated with malnutrition are poorly elucidated in pediatric cancer care. We aimed to better understand characteristics associated with weight-for-height (WHZ) and height-for-age (HAZ) changes for infants and young children during cancer treatment. This retrospective study included 434 patients diagnosed <3 years old from 2007 to 2015 at a large pediatric cancer center. Patients starting treatment outside our center, those with relapsed or secondary malignancies, or with inaccurate information were excluded. Abstracted weights and heights for a 24-month period after treatment initiation were converted to sex-specific and age-specific z scores. Although not statistically different at baseline, patients with hematologic malignancies gained weight over time, while other tumor types did not. Higher treatment intensity and younger age at diagnosis increased odds of clinically significant weight loss. Older children had higher HAZ at diagnosis and HAZ also significantly decreased over time for all examined risk factors, which is distinctly different from patterns in WHZ over time. In conclusion, WHZ and HAZ are affected differently by cancer treatment in infants and young children. We identify key risk factors for weight loss and growth stunting which will be necessary to develop prospective trials to examine anthropometric, biochemical, and patient recorded outcomes around nutrition.

Self-reported late effect symptom clusters among young pediatric cancer survivors.

PURPOSE: Most survivors of childhood cancer experience subsequent chronic conditions but little is known about concurrent symptoms. This study seeks to identify late effect symptom clusters among young pediatric cancer survivors. METHODS: Survivors ≥ 18 or parents of survivors < 18 years enrolled in an institutional cohort study indicated (yes/no) if they experienced certain symptoms after treatment. The sample was randomly divided in half for exploratory factor analyses to identify symptom clusters followed by confirmatory factor analyses. Symptoms with ≥ 10% prevalence were included. Cluster structure generalizability across subgroups was examined using congruence coefficients. RESULTS: The sample included 579 survivors (74% non-Hispanic white, 45% leukemia, 12.8 ± 4.5 years at survey, 5.9 ± 3.5 years since therapy). Respondents averaged three symptoms. Three clusters were identified: (1) gastrointestinal: abdominal pain, diarrhea, constipation, nausea, vomiting (Cronbach's α = 0.74); (2) psychological: depression, anxiety, memory problems, anger management problems, sleep problems (α = 0.71); and (3) neurologic: problems walking, numbness/tingling, fatigue, back pain, chronic pain, weakness/inability to move legs (α = 0.71). Confirmatory factor analysis confirmed the three-cluster structure (standardized root mean square residual: 0.09; parsimonious goodness of fit: 0.96; Bentler-Bonett normed fit index: 0.95). The gastrointestinal and psychological clusters were generalizable across most subgroups while the neurologic cluster varied across age and race/ethnicity subgroups. CONCLUSION: Three distinct late effect symptom clusters were identified in young childhood cancer survivors with gastrointestinal and psychological clusters remaining relatively stable across subgroups. Future studies should focus on the characteristics of patients who experience these symptoms, especially those with high symptom burden, and the synergistic impact on quality of life.

Association of a pediatric palliative oncology clinic on palliative care access, timing and location of care for children with cancer.

BACKGROUND: Most pediatric palliative care (PPC) services are inpatient consultation services and do not reach patients and families in the outpatient and home settings, where a vast majority of oncology care occurs. We explored whether an embedded pediatric palliative oncology (PPO) clinic is associated with receipt and timing of PPC and hospital days in the last 90 days of life. METHODS: Oncology patients (ages 0-25) with a high-risk event (death, relapse/progression, and/or phase I/II clinical trial enrollment) between 07/01/2015 and 06/30/2018 were included. PPO clinic started July 2017. Two cohorts were defined: pre-PPO (high-risk event(s) occurring 07/01/2015-06/30/2017) and post-PPO (high-risk event(s) occurring 07/01/2017-06/30/2018). Descriptive statistics were performed; demographic, disease course, and outcomes variables across cohorts were compared. RESULTS: A total of 426 patients were included (pre-PPO n = 235; post-PPO n = 191). Forty-seven patients with events in both pre- and post-PPO cohorts were included in the post-PPO cohort. Mean age at diagnosis was 8 years. Diagnoses were evenly distributed among solid tumors, brain tumors, and leukemia/lymphoma. Post-PPO cohort patients received PPC more often (45.6% vs. 21.3%, p < 0.0001), for a longer time before death than the pre-PPO cohort (median 88 vs. 32 days, p = 0.027), and spent fewer days hospitalized in the last 90 days of life (median 3 vs. 8 days, p = 0.0084). CONCLUSION: A limited-day, embedded PPO clinic was associated with receipt of PPC and spending more time at home in patients with cancer who had high-risk events. Continued improvements to these outcomes would be expected with additional oncology provider education and PPO personnel.

Defining palliative opportunities in pediatric patients with bone and soft tissue sarcomas.

BACKGROUND: Pediatric patients with sarcomas experience significant morbidity and compromised quality of life throughout their course. These times could be viewed as opportunities for increased subspecialty palliative care (PC). Systematically defining opportunities for additional PC support has not occurred in pediatric oncology. The frequency, timing, and associated factors for palliative opportunities in pediatric patients with sarcomas are unknown. METHODS: A priori, nine palliative opportunities were defined (disease progression or relapse, admission for symptoms, social concerns or end-of-life, intensive care or bone marrow transplant admission, phase 1 trial or hospice enrollment, do-not-resuscitate status). A single-center retrospective review was conducted on patients aged 0-18 years with bone/soft tissue sarcomas who died from January 1, 2012 to November 30, 2017. Demographic, disease, and treatment data were collected. Descriptive statistics were performed. Opportunities were evaluated over quartiles from diagnosis to death. RESULTS: Patients (n = 60) had a mean of nine (SD = 4) palliative opportunities with the majority occurring in the last quartile of the disease course. Number and type of opportunities did not differ by demographics or diagnosis. Eighteen patients (30%) received PC consultation a median of 2.2 months (interquartile range [IQR] 11.5) prior to death. Consultation was unrelated to diagnosis or total opportunities. CONCLUSIONS: Patients with sarcomas incur repeated events warranting subspecialty PC, which increase toward the end-of-life. Increased PC utilization may help decrease suffering and bolster family coping during these episodes. Additional work should further refine if opportunities differ across cancers, and how to incorporate this framework into clinical oncology care to prevent missed opportunities for PC.

Intent and subsequent initiation of human papillomavirus vaccine among young cancer survivors.

BACKGROUND: Despite an increased risk of subsequent human papillomavirus (HPV)-related malignancies, HPV vaccine initiation rates among cancer survivors remain critically low. The purpose of this study was to determine the relationship between HPV vaccine intent and subsequent vaccine initiation among cancer survivors by linking data from a cross-sectional survey with state-based immunization registry records. METHODS: Cancer survivors who were 9 to 26 years old were surveyed 1 to 5 years after their treatment to assess their HPV vaccine initiation status, HPV vaccine intent, sociodemographic factors, and vaccine-related health beliefs. HPV vaccine doses/dates were abstracted from the Georgia Registry for Immunization Transactions for 3.5 years after survey participation. Logistic regression models identified factors associated with vaccine intent and subsequent vaccine initiation. RESULTS: Among survivors who were HPV vaccine-naive at survey participation (n = 103), factors associated with vaccine intent included the following: 1) provider recommendation for the HPV vaccine (odds ratio [OR], 5.0; 95% confidence interval [CI], 1.4-18.1; P = .014), 2) positive general attitude toward vaccines (OR, 4.8; 95% CI, 2.0-11.2; P < .001), and 3) perceived severity of HPV disease (OR, 3.5; 95% CI, 1.2-9.9; P = .02). Of the vaccine-naive patients, 28 initiated the HPV vaccine at a median of 1.1 years after the survey. Initiation was more likely among survivors who had reported vaccine intent (OR, 3.9; 95% CI, 1.2-12.5; P = .02) and was less likely among older survivors (OR per year, 0.7; 95% CI, 0.6-0.9; P < .001). CONCLUSIONS: These findings suggest that provider recommendation for the HPV vaccine plays a role in establishing intent, which then translates into subsequent initiation.

Knowledge of Late Effects Risks and Healthcare Responsibility in Adolescents and Young Adults Treated for Childhood Cancer.

OBJECTIVE: This study aimed to examine the level and predictors of knowledge of late effects risks from childhood cancer treatment in adolescent and young adult (AYA) survivors. METHODS: Seventy-three AYAs, aged 14-21, completed measures of knowledge of late effect risks, executive functioning, and responsibility for health self-management. Sixty-seven parents of these AYA survivors (91.7%) also participated. RESULTS: Survivors demonstrated poor knowledge of their unique risks for treatment-related late effects, with a mean accurate knowledge score of 54.29% (SD = 24.19%). The number of late effects for which survivors were at risk was negatively correlated with risk knowledge (r = -.34, p < .01). Survivors' executive functioning was not related to risk knowledge. In regression analyses, survivor age positively predicted accurate knowledge of late effects risks, and the number of late effects risk was a negative predictor. In separate models, survivor self-report of AYA responsibility for health self-management did not predict knowledge (R2 = .39, F = 10.86, p < .01), but parent proxy-report was a significant positive predictor (R2 = .38, F = 9.62, p < .01). Parental involvement was not a significant predictor in either model. CONCLUSION: There are significant knowledge gaps among AYA survivors of childhood cancer, which appear to be related to younger AYA age and lower levels of AYA responsibility for health self-management. Additional intervention is critical to increase AYA knowledge of their risk for late effects in order to promote continued engagement in long-term follow-up care and surveillance across the lifespan.

Readiness for transition and health-care satisfaction in adolescents with complex medical conditions.

BACKGROUND: The purpose of this study is to examine contributions to patient perceptions of transition readiness and satisfaction with care amongst adolescents and young adults (AYAs) with complex health conditions engaging in paediatric care. METHODS: Participants included 94 patients aged 14-20 years (M = 16.41, SD = 1.56) with cystic fibrosis (n = 31), sickle cell disease (n = 27), and solid organ transplants (n = 36). Participants completed self-report questionnaires and medical providers completed measures of their medication regimen complexity. One-way analysis of variance compared differences between disease groups on study variables. Pearson product-moment correlation coefficients and linear regression models evaluated factors associated with AYA reported transition readiness and satisfaction with health care. RESULTS: There were no significant differences between disease groups on patient-reported transition readiness, barriers to medication adherence, health care self-management, or satisfaction. Patient age, self-reported health-care responsibility, medication barriers, and academic performance predicted a large portion of the variance in AYA perceptions of transition readiness (R2  = 0.27, F (4, 83) = 7.74, p < 0.001, Cohen's f2 = 0.37). Patient gender, self-reported health-care responsibility, and medication barriers predicted a medium portion of the variance in AYA satisfaction with health care (R2  = 0.23, F (3, 88) = 8.56, p < 0.001, Cohen's f2 = 0.30). CONCLUSIONS: Patient perceptions of health care self-management and barriers to medication adherence are important predictors of readiness for transition and satisfaction with care. Considering a holistic approach that includes these factors allows for improved understanding of individual needs for transition interventions that can improve adult outcomes for individuals with complex health conditions.

Perceptions of risk of infertility among male survivors of childhood cancer: A report from the Childhood Cancer Survivor Study.

BACKGROUND: The objective of the current study was to characterize and identify factors associated with perceptions of risk of infertility among adult male survivors of childhood cancer. METHODS: A total of 1233 adult male survivors from the Childhood Cancer Survivor Study who were without a history of disease recurrence or subsequent malignancy reported their perceptions of their risk of infertility compared with men never diagnosed with cancer. Survivors were a median age of 37.8 years (range, 22.0-58.7 years) and were 28.4 years from their diagnosis (range, 21.4-39.2 years). Multivariable logistic regression evaluated factors associated with perceptions of risk. RESULTS: Overall, 35.9% of the survivors (443 of 1233 survivors) reported perceptions of their risk of infertility that were discordant with their actual risk based on previous cancer treatment exposures. Discordant perceptions were equally common among men exposed to gonadotoxic therapies (36.3%; 311 of 857 men) and those with no history of gonadotoxic exposure (35.1%; 132 of 376 men). Survivors who fathered children (odds ratio [OR], 4.14; 95% confidence interval [95% CI], 2.74-6.24), had no survivor-focused health care (OR, 3.07; 95% CI, 1.57-5.99), were nonwhite (OR, 2.28; 95% CI, 1.10-4.75), and were of lower income were more likely to report no increased risk of infertility after gonadotoxic treatment. Perceptions of increased risk of infertility among men with no history of gonadotoxic treatment were predicted by never having fathered a child (OR, 1.88; 95% CI, 1.17-3.03), recent participation in survivor-focused health care (OR, 2.11; 95% CI, 1.01-4.42), and higher educational achievement. CONCLUSIONS: Many male survivors of childhood cancer are unaware of how their cancer treatments could impact their reproductive health, underscoring the need for all patients to receive education regarding their risk of infertility throughout the continuum of cancer care.

A brief survey of health habits among childhood cancer survivors.

Using a survey, we assessed four health habits in 468 pediatric cancer survivors. Approximately 75% were at goal for ≥1 behavior-44% were active ≥1 hr per day, 40% engaged in ≤1 hr of screen time a day, 34% consumed sweetened beverages not often, and 4% ate >4 servings of fruits and vegetables per day. Survivors' age was associated with being active (P < 0.001) and limited screen time (P = 0.001). Males were more likely to be active (P = 0.003). The most common combination of goal behaviors was activity and screen time. Encouraging healthy behaviors may decrease the burden of late effects in survivors.

Gemcitabine/nab-paclitaxel for pediatric relapsed/refractory sarcomas.

BACKGROUND: Pediatric patients with relapsed/refractory sarcomas have poor outcomes and need novel therapies that provide disease control while maintaining an acceptable quality of life. The activity and toxicity of gemcitabine and nab-paclitaxel in combination has not been reported in pediatrics. PROCEDURE: We reviewed the records of fifteen relapsed/refractory patients and one treatment-naïve patient who received gemcitabine/nab-paclitaxel at our institution. RESULTS: Sixteen patients (median age 13.5 years, range 3-19 years) received 53 cycles of gemcitabine/nab-paclitaxel. Twenty-nine cycles (55%) resulted in ≥Grade 3 toxicity, with nonhematologic Grade ≥3 toxicities occurring in only eight of 53 cycles (15%). Patients received red blood cell and platelet transfusions in 23% and 4% of cycles, respectively. Grade ≥3 infectious toxicities occurred in 4% of cycles. Of 14 patients with measurable disease, there were no complete responses (CR), one partial response (PR; 7%), and six patients (43%) with stable disease (SD; median SD: 4.5 months, range: 2-19 months). In total, 31% of the patients derived clinical benefit (CR + PR + SD ≥ 4 months). Median time to progression was 72 days with a 4-month progression-free survival of 31% ± 12% and 1-year overall survival of 19% ± 10%. With a median follow-up for all 16 patients of 21 months from the first treatment with gemcitabine/nab-paclitaxel, one (6%) remains alive with disease. CONCLUSIONS: Gemcitabine/nab-paclitaxel is a relatively safe regimen with mainly hematologic toxicities. It offers a well-tolerated, palliative option providing clinical benefit in a subset of patients. A phase I trial of this combination is underway.

Yield of screening echocardiograms during pediatric follow-up in survivors treated with anthracyclines and cardiotoxic radiation.

BACKGROUND: Guidelines published by the Children's Oncology Group recommend screening echocardiograms for childhood cancer survivors exposed to anthracyclines and/or cardiotoxic radiation. This study aims to assess risk factors for cardiac late effects while evaluating the overall yield of screening echocardiograms. PROCEDURE: Demographics, exposures, and echocardiogram results were abstracted from the medical records of survivors diagnosed at ≤ 21 years old and ≥ 2 years off therapy who were exposed to anthracyclines and/or potentially cardiotoxic radiotherapy. Descriptive statistics and logistic regressions were performed and the yield of screening echocardiograms was calculated. RESULTS: Of 853 patients, 1,728 screening echocardiograms were performed, and 37 patients had an abnormal echocardiogram (overall yield 2.1%). Yields were only somewhat higher in more frequently screened patients. Risk factors for an abnormal result included anthracycline dose of ≥300 mg/m2 (adjusted odds ratio [aOR] 3.1; 95% confidence interval [CI]: 1.3-7.2; P < 0.01) with a synergist relationship in patients who also received radiation doses ≥30 Gy (aOR 7.0; 95% CI: 1.6-31.9; P = 0.01), as well as autologous bone marrow transplant (OR 3.3; 95% CI: 1.3-8.5; P = 0.01). Sex, race, age at diagnosis, and cyclophosphamide exposure were not statistically significant risk factors, and no patient receiving <100 mg/m2 anthracycline dose without concomitant radiation had an abnormal echocardiogram. CONCLUSIONS: Dose-dependent and synergist anthracycline and cardiotoxic radiotherapy risks for developing cardiomyopathy were confirmed. However, previously identified risk factors including female sex, black race, and early age at diagnosis were not replicated in this cohort. The yields showed weak correlation across frequency categories. Echocardiographic screening recommendations for low-risk pediatric patients may warrant re-evaluation.

Risk factors and surveillance for reduced bone mineral density in pediatric cancer survivors.

BACKGROUND: Pediatric cancer survivors are at increased risk of developing low bone mineral density (BMD) due to cancer treatment. This study assessed the yield of screening for low BMD in pediatric-aged cancer survivors as per the Children's Oncology Group Long-Term Follow-Up (COG-LTFU) Guidelines, which recommend screening survivors who received steroids, methotrexate, or hematopoietic cell transplant (HCT). METHODS: This is a retrospective cohort study of 475 pediatric blood cancer and noncentral nervous system solid tumor survivors screened for low BMD with dual-energy X-ray absorptiometry (DXA) as per the COG-LTFU Guidelines from 2003 to 2010. Risk factors for low BMD (DXA Z-score ≤-2) were evaluated by univariate and multivariate analysis. RESULTS: The mean DXA Z-score was -0.1 for both whole body and lumbar spine measurements. Among at-risk survivors, 8.2% (39/475) had low BMD. Multivariate analysis of survivors with low BMD showed significant association with male gender (odds ratio [OR] 3.4, 95% confidence interval [CI], 1.3-9.0), exposure to total body irradiation (TBI), cranial, or craniospinal radiation (OR 5.2, 95% CI, 1.8-14.9), and gonadal dysfunction (OR 4.3, 95% CI, 1.4-13.0). Methotrexate exposure was not significantly associated with low BMD. Survivors receiving HCT had a reduced risk of low BMD (OR 0.2, 95% CI, 0.1-0.9). CONCLUSION: The highest risk factors for low BMD were male gender, exposure to TBI, cranial, or craniospinal radiation, and gonadal dysfunction. Survivors receiving methotrexate or HCT therapy have the lowest risk for low BMD among those screened. Future studies should investigate risk of low BMD for survivors receiving HCT without radiation exposure.

Erectile Dysfunction in Male Survivors of Childhood Cancer-A Report From the Childhood Cancer Survivor Study.

INTRODUCTION: With survival rates higher than 80%, the number of survivors from pediatric cancer continues to increase. Late effects resulting from cancer and cancer therapy are being characterized, but little information exists on sexual health for men who have survived childhood cancer. AIM: To assess erectile dysfunction (ED) in men who survived childhood and adolescent cancers and to identify potential risk factors for ED. METHODS: In total, 1,622 men and 271 eligible brothers in the Childhood Cancer Survivor Study cohort completed the Male Health Questionnaire, which provided information on sexual practices and sexual function. Combined with demographic, cancer, and treatment information from medical record abstraction, results of the Male Health Questionnaire were analyzed using multivariable modeling. The International Index of Erectile Function was used to identify ED in subjects. MAIN OUTCOME MEASURE: International Index of Erectile Function. RESULTS: Survivors (mean age = 37.4 years, SD = 7.3 years) reported significantly lower sexual activity in the year before the survey than the brothers (mean age = 38.8 years, SD = 8.5 years) without cancer. ED was reported by 12.3% (95% CI = 10.4-14.3) of survivors and 4.2% (95% CI = 2.0-7.9) of brothers. Survivors showed significantly higher relative risk (RR) for ED (RR = 2.63, 95% CI = 1.40-4.97). In addition to older age, survivors who were exposed to higher-dose (≥10 Gy) testicular radiation (RR = 3.55, 95% CI = 1.53-8.24), had surgery on the spinal cord or nerves (RR = 2.87, 95% CI = 1.36-6.05), prostate surgery (RR = 6.56, 95% CI = 3.84-11.20), or pelvic surgery (RR = 2.28, 95% CI = 1.04-4.98) were at higher risk for ED. CONCLUSION: Men who have survived childhood cancer have a greater than 2.6-fold increased risk for ED and certain cancer-specific treatments are associated with increased risk. Attention to sexual health, with its physical and emotional implications, and opportunities for early detection and intervention in these individuals could be important.

Yield of Urinalysis Screening in Pediatric Cancer Survivors.

BACKGROUND: The Children's Oncology Group (COG) publishes consensus guidelines with screening recommendations for early identification of treatment-related morbidities among childhood cancer survivors. We sought to estimate the yield of recommended yearly urinalysis screening for genitourinary complications as per Version 3.0 of the COG Long-Term Follow-Up Guidelines and identify possible risk factors for abnormal screening in a survivor population. PROCEDURE: A database of pediatric cancer survivors evaluated between January 2008 and March 2012 at Children's Healthcare of Atlanta was queried for survivors at risk for genitourinary late effects. The frequency of abnormal urinalyses (protein ≥1+ and/or presence of glucose and/or ≥5 red blood cells per high power field) was estimated. Risk factors associated with abnormal screening were identified. RESULTS: Chart review identified 773 survivors (57% male; 67% Caucasian; 60% leukemia/lymphoma survivors; mean age at diagnosis, 5.7 years [range: birth to 17.7 years]; time from diagnosis to initial screening, 7.6 years [range: 2.3 to 21.5 years]) who underwent urinalysis. Abnormal results were found in 78 (5.3%) of 1,484 total urinalyses. Multivariable analysis revealed higher dose ifosfamide (odds ratio [OR] = 6.8, 95% confidence interval [CI] 2.9-16.0) and total body irradiation (TBI, OR = 3.0, 95% CI 1.0-8.4) as significant risk factors for abnormal initial urinalysis screening. CONCLUSIONS: Pediatric cancer survivors exposed to higher dose ifosfamide or TBI may be at higher risk of abnormal findings on urinalysis screening. Targeted screening of these higher risk patients should be considered.

Analysis of Risk Factors for Abnormal Pulmonary Function in Pediatric Cancer Survivors.

BACKGROUND: Childhood cancer survivors are at increased risk for pulmonary-related morbidity and mortality. The Children's Oncology Group Long-Term Follow-Up (COG-LTFU) guidelines recommend pulmonary function testing after treatment with bleomycin, busulfan, carmustine, lomustine, thoracic radiation, bone marrow transplant, or pulmonary surgery. The aim of this analysis was to determine the prevalence of pulmonary function abnormalities in a pediatric survivor cohort. PROCEDURE: Patients ≥5 years old seen in our survivor clinic with at least one exposure outlined by COG-LFTU Guidelines were included. Original pulmonary function test (PFT) results were obtained and blindly reinterpreted by a single reviewer. Demographic, diagnosis, treatment factors, and clinical and/or patient-reported symptoms of cough, wheeze, and/or dyspnea were abstracted from their medical record. RESULTS: Overall, 143 (63.3%) survivors had PFT results available; 55.2% were male, 49.7% were white, and the mean age was 14.1 ± 4.8 years. Abnormal PFTs were found in 65.0% (n = 93) with 21.0% having multiple abnormalities. Specifically, 41.3% had hyperinflation, 25.9% had obstructive, and 13.3% had restrictive disease. Patients diagnosed at <5 years were more likely to have a pulmonary abnormality (P = 0.04); a majority of those diagnosed <5 years underwent pulmonary surgery or thoracic radiation. Regardless of the presence of a PFT abnormality, more than 80% of survivors were asymptomatic (82.9% vs.81.5%; P-value = 0.54). CONCLUSIONS: Almost two-thirds of survivors screened per the COG-LTFU Guidelines had an abnormal PFT but a majority reported no clinical symptoms. Hyperinflation was the most prevalent abnormality.
