Children's Oncology Group's 2013 blueprint for research: nursing discipline.

Integration of the nursing discipline within cooperative groups conducting pediatric oncology clinical trials provides unique opportunities to maximize nursing's contribution to clinical care, and to pursue research questions that extend beyond cure of disease to address important gaps in knowledge surrounding the illness experience. Key areas of importance to the advancement of the nursing discipline's scientific knowledge are understanding the effective delivery of patient/family education, and reducing illness-related distress, both of which are integral to facilitating parental/child coping with the diagnosis and treatment of childhood cancer, and to promoting resilience and well-being of pediatric oncology patients and their families.

PROMIS pediatric measures in pediatric oncology: valid and clinically feasible indicators of patient-reported outcomes.

BACKGROUND: Establishing the ability of children and adolescents with cancer to complete the NIH-sponsored PROMIS pediatric measures electronically and the preliminary validity estimates of the measures (both full item banks and short forms) in pediatric oncology will contribute to our knowledge of the impact of cancer treatment on these young patients. PROCEDURES: A total of 203 8- to 17-year olds were administered eight PROMIS pediatric measures in a cross-sectional study design to establish known-group validity. Of the 200 who completed all or most of the items, a slight majority were male (55.5%) and white (54%). Patients were either undergoing treatment for cancer (n = 93) or in survivorship following treatment for cancer (n = 107). Measures were completed using computer interface during an in-person interaction with researchers. RESULTS: Only 3 of 203 participants did not complete the PROMIS pediatric measures. As hypothesized, participants in treatment were significantly different (worse) on parent-reported clinical indicators (blood counts, fatigue, and appetite) and on seven self-reported measures (depression, anxiety, peer relationships, pain interference, fatigue, upper extremity function, and mobility) from participants in survivorship. Females reported worse fatigue, anger, and pain interference than males. Worse patient-reported outcomes for patients in active treatment persisted after adjusting for potential confounding variables. CONCLUSIONS: Children and adolescents in treatment for cancer or in survivorship and ranging from 8 to 17 years of age can complete multiple PROMIS pediatric measures using a computer interface during an outpatient clinic visit or inpatient admission. Findings establish known-group validity for PROMIS pediatric measures in pediatric oncology.

Association of projected transfusional iron burden with treatment intensity in childhood cancer survivors.

BACKGROUND: Packed red blood cell (PRBC) transfusion is a mainstay in childhood cancer treatment, but has potential for inducing iron overload. The purpose of this study was to determine whether treatment intensity is predictive of projected iron burden resulting from PRBC transfusions among survivors of several forms of childhood cancer. PROCEDURE: This retrospective cohort study involved patients treated at Children's Hospital Los Angeles (CHLA) between June 1, 2004 and December 31, 2009. Clinical/demographic data were abstracted from medical records. Treatment Intensity Level was determined for each patient using a published scale. Adjusted cumulative PRBC transfusion volume for each patient (ml/kg) was used to compute the adjusted total iron burden (mg/kg) based upon the average hematocrit of the product. RESULTS: Median age of the cohort (n = 214) was 7.9 years (range 0.2-20.2). One hundred and fourteen (53.3%) were male and 129 (60.3%) were Hispanic/Latino. Diagnoses included acute leukemia and six solid tumors, management of which represents a range of cancer treatment intensities. The number of transfusions, transfusion volumes, and projected iron burden were significantly increased and exceeded upper limits of normal among patients with higher treatment intensity. Multivariate analysis found younger age and lower hemoglobin at diagnosis to be associated with greater iron burden after adjusting for treatment intensity. CONCLUSION: Greater treatment intensity is associated with need for more PRBC transfusions, and thus increased risk of iron overload among childhood cancer survivors. Iron overload may represent another clinically significant late effect following childhood cancer treatment.

Reconsidering Physical Activity Restrictions for Mononephric Survivors of Childhood Cancer: A Report From the Children's Oncology Group.

Although traditional recommendations for mononephric childhood cancer survivors are to avoid contact sports in order to protect the remaining kidney, review of available evidence suggests that the majority of renal loss is caused by accidents not involving sports. An interdisciplinary team performed a review of the English literature published from 1999 to 2012 within the PubMed, Cochrane, Google Scholar, and National Guidelines Clearinghouse databases. The level of evidence and proposed recommendations were graded according to an established rubric and GRADE criteria. Our review found that kidney loss is most commonly caused by nonsports activities such as motor vehicle accidents and falls, implying that restrictions on sports-related activity in mononephric pediatric survivors are not well supported. This favors encouraging ordinary sports and related activities without restriction in mononephric childhood cancer survivors because the known benefits of exercise outweigh the exceedingly low risk of renal loss. Accordingly, activity recommendations for mononephric patients have been revised in the most current version of the Children's Oncology Group Long-term Follow-Up Guidelines for Survivors of Childhood, Adolescent and Young Adult Cancers. This has important implications for this and similar populations who may now undertake individual and organized sports without undue regard for their mononephric status.

Patient/Family Education for Newly Diagnosed Pediatric Oncology Patients.

There is a paucity of data to support evidence-based practices in the provision of patient/family education in the context of a new childhood cancer diagnosis. Since the majority of children with cancer are treated on pediatric oncology clinical trials, lack of effective patient/family education has the potential to negatively affect both patient and clinical trial outcomes. The Children's Oncology Group Nursing Discipline convened an interprofessional expert panel from within and beyond pediatric oncology to review available and emerging evidence and develop expert consensus recommendations regarding harmonization of patient/family education practices for newly diagnosed pediatric oncology patients across institutions. Five broad principles, with associated recommendations, were identified by the panel, including recognition that (1) in pediatric oncology, patient/family education is family-centered; (2) a diagnosis of childhood cancer is overwhelming and the family needs time to process the diagnosis and develop a plan for managing ongoing life demands before they can successfully learn to care for the child; (3) patient/family education should be an interprofessional endeavor with 3 key areas of focus: (a) diagnosis/treatment, (b) psychosocial coping, and (c) care of the child; (4) patient/family education should occur across the continuum of care; and (5) a supportive environment is necessary to optimize learning. Dissemination and implementation of these recommendations will set the stage for future studies that aim to develop evidence to inform best practices, and ultimately to establish the standard of care for effective patient/family education in pediatric oncology.

Development of risk-based guidelines for pediatric cancer survivors: the Children's Oncology Group Long-Term Follow-Up Guidelines from the Children's Oncology Group Late Effects Committee and Nursing Discipline.

The Children's Oncology Group Long-Term Follow-Up Guidelines for Survivors of Childhood, Adolescent, and Young Adult Cancers are risk-based, exposure-related clinical practice guidelines intended to promote earlier detection of and intervention for complications that may potentially arise as a result of treatment for pediatric malignancies. Developed through the collaborative efforts of the Children's Oncology Group Late Effects Committee, Nursing Discipline, and Patient Advocacy Committee, these guidelines represent a statement of consensus from a multidisciplinary panel of experts in the late effects of pediatric cancer treatment. The guidelines are both evidence-based (utilizing established associations between therapeutic exposures and late effects to identify high-risk categories) and grounded in the collective clinical experience of experts (matching the magnitude of risk with the intensity of screening recommendations). They are intended for use beginning 2 or more years following the completion of cancer therapy; however, they are not intended to provide guidance for follow-up of the survivor's primary disease. A complementary set of patient education materials ("Health Links") was developed to enhance follow-up care and broaden the application of the guidelines. The information provided in these guidelines is important for health care providers in the fields of pediatrics, oncology, internal medicine, family practice, and gynecology, as well as subspecialists in many fields. Implementation of these guidelines is intended to increase awareness of potential late effects and to standardize and enhance follow-up care provided to survivors of pediatric cancer throughout the lifespan. The Guidelines, and related Health Links, can be downloaded in their entirety at www.survivorshipguidelines.org.

Creating a novel structure for nursing research in a cooperative clinical trials group: the Children's Oncology Group experience.

OBJECTIVE: To describe a novel structure designed to integrate nursing research into the Children's Oncology Group (COG). DATA SOURCES: Review articles, reports, and newsleters. CONCLUSION: A new structure using nurse researcher-advanced practice nurse dyads has succesfully integrated nurse researchers into COG scientific activity, as evidenced by the development of concept proposals, companion protocols, nursing objectives in therapeutic trials, and nurse-led publications. IMPLICATIONS FOR NURSING PRACTICE: This provides a promising method for integrating nurse researchers and increasing multidisciplinary research collaboration in cooperative oncology group.

Characterization of transfusion-derived iron deposition in childhood cancer survivors.

BACKGROUND: Childhood cancer survivors (CCS) receiving packed red blood cell (PRBC) transfusions may have increased risk for vital organ iron deposition causing serious late effects. METHODS: This cross-sectional cohort study of a CCS cohort quantified organ iron content by magnetic resonance imaging. Iron status by serum markers and hemochromatosis gene mutation status were assessed. RESULTS: Seventy-five patients who had received a range (0-392 mL/kg) of cumulative PRBC transfusion volumes were enrolled (median age 14 years, range 8-25.6 years at evaluation). Median follow-up time was 4.4 years, and median time since last transfusion was 4.9 years. Cancer diagnoses included acute lymphoblastic or myelogenous leukemia (ALL/AML; n = 33) and solid tumors (n = 42). Liver and pancreatic iron concentrations were elevated in 36 of 73 (49.3%) and 19 of 72 (26.4%) subjects, respectively. Cardiac iron concentration was not increased in this cohort. In multivariate analysis, cumulative PRBC volume (P < 0.0001) and older age at diagnosis (P < 0.0001) predicted elevated liver iron concentration. CONCLUSIONS: Iron overload (IO) may occur in children and adolescents/young adults treated for cancer and is associated with cumulative PRBC transfusion volume and age at diagnosis. IMPACT: These findings have implications for development of monitoring and management guidelines for cancer patients and survivors at risk for IO, exploration of the additive risk of liver/pancreatic damage from chemotherapeutic exposures, and health education to minimize further liver/pancreatic damage from exposures such as excessive alcohol intake and hepatotoxic medications.

Cancer survivor identity shared in a social media intervention.

This study investigates how cancer survivors construct their identities and the impact on their psychological health, as measured by depression and survivor self-efficacy. Fourteen young adult survivors of pediatric cancer participated in a customized social networking and video blog intervention program, the LIFECommunity, over a 6-month period. Survivors were asked to share their stories on various topics by posting video messages. Those video blog postings, along with survey data collected from participants, were analyzed to see how cancer survivors expressed their identities, and how these identities are associated with survivors' psychosocial outcomes. In survivors who held negative stereotypes about cancer survivors, there was a positive relationship with depression while positive stereotypes had a marginal association with cancer survivor efficacy. Findings indicate that although pediatric cancer survivors often do not publicly discuss a "cancer survivor identity," they do internalize both positive and negative stereotypes about cancer survivorship. It is important for practitioners to be aware of the long-term implications of cancer survivor identity and stereotypes.
