Pain in long-term adult survivors of childhood cancers and their siblings: a report from the Childhood Cancer Survivor Study

Perioperative factors associated with persistent opioid use after extensive abdominal surgery in children and adolescents: A retrospective cohort study

BACKGROUND

In adults, preoperative opioid use and higher perioperative opioid consumption have been associated with higher odds of persistent opioid use after surgery. There are limited data on the prevalence and factors associated with persistent opioid use after major oncologic surgery in children.

AIMS

In this study, we sought to determine the prevalence and factors associated with the development of persistent opioid use in a group of children and adolescents who had undergone cytoreductive surgery with hyperthermic intraperitoneal chemotherapy.

METHODS

A retrospective study of patients ≤19 years of age was performed. Univariable logistic regression was used to assess factors associated with a postdischarge persistent opioid use of up to 6 months.

RESULTS

Eighty-six children were identified. The median age was 12 years, and 43% were female. The proportion of patients with persistent opioid use over the immediate 3, 6, 12 and 24 postdischarge months was 54/77 (70%), 18/51 (35%), 13/45 (29%), and 3/24 (13%), respectively. The daily average in-patient pain scores were higher in the group of children who subsequently developed persistent opioid use of up to 6 months (estimated difference 0.5, 95% confidence interval [CI]: 0.3, 0.8, P < .01). Furthermore, higher postoperative opioid consumption was associated with greater odds of a subsequent persistent opioid use of up to 6 months (odds ratio 1.03, 95% CI: 1.00, 1.07, P = .05).

CONCLUSION

In this retrospective study of children and adolescents who had undergone a major oncologic surgery, higher in-patient pain scores and higher postoperative opioid consumption were associated with a persistent opioid use of up to 6 months.

Cold Pressor Pain Response in Children With Cancer

OBJECTIVE

The goal of this study was to examine pain responses in pediatric patients with cancer.

METHOD

Children (ages 6 to 18) undergoing treatment for cancer (N=68) completed the cold pressor task.

RESULTS

Average pain tolerance was 118.22 seconds (SD=101.18) and 40% of the children kept their hand in the water the entire 4-minute ceiling. On a 0 to 10 numeric rating scale, children reported a pain severity of 5.07 (SD=3.47) at their first report of pain, a pain severity of 5.94 (SD=3.54) at their maximum report of pain, and a pain severity of 5.33 (SD=3.72) at the time they reached pain tolerance. Children receiving chemotherapy agents (N=56) with possible neuropathic effects exhibited higher pain tolerance compared with children not receiving such treatments (N=10), β=0.84, SE=0.38, Wald χ1=4.88, P=0.027, hazard ratio=2.33, 95% confidence interval (1.10-4.92).

CONCLUSIONS

This study provides data on experimental pain responses in a sample of children undergoing cancer treatment and suggests that pain experience may be moderated by cancer treatment type.

Neurodevelopmental consequences of pediatric cancer and its treatment: applying an early adversity framework to understanding cognitive, behavioral, and emotional outcomes

Today, children are surviving pediatric cancer at unprecedented rates, making it one of modern medicine's true success stories. However, we are increasingly becoming aware of several deleterious effects of cancer and the subsequent "cure" that extend beyond physical sequelae. Indeed, survivors of childhood cancer commonly report cognitive, emotional, and psychological difficulties, including attentional difficulties, anxiety, and posttraumatic stress symptoms (PTSS). Cognitive late- and long-term effects have been largely attributed to neurotoxic effects of cancer treatments (e.g., chemotherapy, cranial irradiation, surgery) on brain development. The role of childhood adversity in pediatric cancer - namely, the presence of a life-threatening disease and endurance of invasive medical procedures - has been largely ignored in the existing neuroscientific literature, despite compelling research by our group and others showing that exposure to more commonly studied adverse childhood experiences (i.e., domestic and community violence, physical, sexual, and emotional abuse) strongly imprints on neural development. While these adverse childhood experiences are different in many ways from the experience of childhood cancer (e.g., context, nature, source), they do share a common element of exposure to threat (i.e., threat to life or physical integrity). Therefore, we argue that the double hit of early threat and cancer treatments likely alters neural development, and ultimately, cognitive, behavioral, and emotional outcomes. In this paper, we (1) review the existing neuroimaging research on child, adolescent, and adult survivors of childhood cancer, (2) summarize gaps in our current understanding, (3) propose a novel neurobiological framework that characterizes childhood cancer as a type of childhood adversity, particularly a form of early threat, focusing on development of the hippocampus and the salience and emotion network (SEN), and (4) outline future directions for research.

Perceptions of Adolescents With Cancer Related to a Pain Management App and Its Evaluation: Qualitative Study Nested Within a Multicenter Pilot Feasibility Study

BACKGROUND

Pain in adolescents with cancer is common and negatively impacts health-related quality of life. The Pain Squad+ smartphone app, capable of providing adolescents with real-time pain management support, was developed to enhance pain management using a phased approach (ie, systematic review, consensus conference and vetting, iterative usability testing cycles). A 28-day Pain Squad+ pilot was conducted with 40 adolescents with cancer to evaluate the feasibility of implementing the app in a future clinical trial and to obtain estimates of treatment effect.

OBJECTIVE

The objective of our nested qualitative study was to elucidate the perceptions of adolescents with cancer to determine the acceptability and perceived helpfulness of Pain Squad+, suggestions for app improvement, and satisfaction with the pilot study protocol.

METHODS

Post pilot study participation, telephone-based, semistructured, and audio-recorded exit interviews were conducted with 20 adolescents with cancer (12-18 years). All interviews were transcribed and independently coded by 2 study team members. Content analysis was conducted to identify data categories and overarching themes.

RESULTS

Five major themes comprising multiple categories and codes emerged. These themes focused on the acceptability of the intervention, acceptability of the study, the perceived active ingredients of the intervention, the suitability of the intervention to adolescents' lives, and recommendations for intervention improvement.

CONCLUSIONS

Overall, Pain Squad+ and the pilot study protocol were acceptable to adolescents with cancer. Suggestions for intervention and study improvements will be incorporated into the design of a future randomized clinical trial (RCT) aimed at assessing the effectiveness of Pain Squad+ on adolescents with cancer health outcomes.

Implementation and preliminary effectiveness of a real-time pain management smartphone app for adolescents with cancer: A multicenter pilot clinical study

BACKGROUND

Pain in adolescents with cancer (12-18 years) is common and negatively impacts health-related quality of life (HRQL). The Pain Squad+ smartphone app, which provides adolescents with real-time pain self-management support, was developed to address this issue. This study evaluated the implementation of the app to inform a future randomized controlled trial (RCT) and obtain treatment effect estimates for pain intensity, pain interference, HRQL, and self-efficacy.

PROCEDURE

A one-group baseline/poststudy design with 40 adolescents recruited from two pediatric tertiary care centers was used. Baseline questionnaires were completed and adolescents used the app at least twice daily for 28 days, receiving algorithm-informed self-management advice depending on their reported pain. A nurse received alerts in response to sustained pain and contacted adolescents to assist in pain care. Poststudy questionnaires were completed. Descriptive analyses, with exploratory inferential testing conducted on health outcome data, were used to address study aims.

RESULTS

Most (40/52; 77%) eligible adolescents participated. Two participants withdrew participation. Intervention fidelity was impacted by technical difficulties (occurring for 15% of participants) and a prolonged time for nurse contact in the event of sustained pain. Adherence to pain reporting was 68.8 ± 38.1%. Outcome measure completion rates were high and the intervention was acceptable to participants. Trends in improvements in pain intensity, pain interference, and HRQL were significant, with effect sizes of 0.23-0.67.

CONCLUSIONS

Implementation of Pain Squad+ is feasible and the app appears to improve pain-related outcomes for adolescents with cancer. A multicenter RCT will be undertaken to examine app effectiveness.

Development of a mHealth Real-Time Pain Self-Management App for Adolescents With Cancer: An Iterative Usability Testing Study [Formula: see text]

PURPOSE

A user-centered design approach was used to refine the mHealth Pain Squad+ real-time pain self-management app for adolescents with cancer for its usability (defined as being easy to use, easy to understand, efficient to complete, and acceptable).

METHOD

Three iterative usability testing cycles involving adolescent observation and interview were used to achieve this objective. During each cycle, adolescents used the app while "thinking aloud" about issues encountered. Observed difficulties and errors were recorded and a semistructured interview about the experience was conducted. Using a qualitative conventional content analysis approach, themes related to app usability were identified.

RESULTS

Participants required an average of 4.3 minutes to complete the pain assessment component of Pain Squad+. Overall, the app was acceptable. Problematic issues related to software malfunction, interface design flaws, and confusing text. Software revisions were made to address each issue.

CONCLUSION

The multifaceted usability approach used provided insight into how a real-time app can be made acceptable to adolescents with cancer and succeeded in developing a Pain Squad+ app that is fit for future effectiveness testing.

Pain assessment and management in paediatric oncology: a cross-sectional audit

AIMS AND OBJECTIVES

To describe the pain assessment and management practices documented by health professionals within a tertiary-level Children's Cancer Centre and to evaluate how these practices were compared with international recommendations.

BACKGROUND

Children with cancer are vulnerable to pain due to the intensity of antineoplastic therapy. Therefore, it is imperative to ensure that current pain management practices provided to paediatric oncology inpatients are of a high quality.

DESIGN

A single-site cross-sectional audit.

METHODS

A 24-hour period of documented pain-related care in randomly selected inpatients of an Australian tertiary-level Children's Cancer Centre was examined. The current pain management practices were audited over a two-month period resulting in 258 episodes of pain-related care being reviewed.

RESULTS

Pain related to medical treatment for cancer was common (n = 146/258, 57%) and persistent. The presence of pain was not consistently recorded by health professionals (n = 75/146, 51%). Pain was mild (n = 26/75, 35%) and opioids were the mainstay of pain management interventions (n = 63/112, 56%). Adjuvants were an important component of pain management (n = 47/112, 42%), and nonpharmacological methods of managing pain were under-represented in this audit (n = 38/146, 26%). According to the Pain Management Index, pain was appropriately managed for the majority of children (n = 65/76, 87%).

CONCLUSIONS

Pain management practices did not fully reflect the recommendations of contemporary paediatric pain management. Due to limitations in the documentation of children's pain, it was difficult to determine the effectiveness of pain management interventions.

RELEVANCE TO CLINICAL PRACTICE

This study highlights the ongoing problem of pain for children receiving antineoplastic therapy. It is recommended that health professionals routinely screen for the presence of pain during hospitalisation and assess the efficacy of pain-related care.

Chronic Pain in Children and Adolescents: Diagnosis and Treatment of Primary Pain Disorders in Head, Abdomen, Muscles and Joints

Primary pain disorders (formerly "functional pain syndromes") are common, under-diagnosed and under-treated in children and teenagers. This manuscript reviews key aspects which support understanding the development of pediatric chronic pain, points to the current pediatric chronic pain terminology, addresses effective treatment strategies, and discusses the evidence-based use of pharmacology. Common symptoms of an underlying pain vulnerability present in the three most common chronic pain disorders in pediatrics: primary headaches, centrally mediated abdominal pain syndromes, and/or chronic/recurrent musculoskeletal and joint pain. A significant number of children with repeated acute nociceptive pain episodes develop chronic pain in addition to or as a result of their underlying medical condition "chronic-on-acute pain." We provide description of the structure and process of our interdisciplinary, rehabilitative pain clinic in Minneapolis, Minnesota, USA with accompanying data in the treatment of chronic pain symptoms that persist beyond the expected time of healing. An interdisciplinary approach combining (1) rehabilitation; (2) integrative medicine/active mind-body techniques; (3) psychology; and (4) normalizing daily school attendance, sports, social life and sleep will be presented. As a result of restored function, pain improves and commonly resolves. Opioids are not indicated for primary pain disorders, and other medications, with few exceptions, are usually not first-line therapy.

Sleep Disruption in Pediatric Cancer Survivors: Conceptual Framework and Opportunities for Clinical Assessment and Behavioral Treatment

Sleep disruption is a commonly reported consequence of cancer and its treatment in pediatric patients and survivors. This review summarizes common sleep concerns in this population and introduces a multidimensional framework of risk factors specific to childhood cancer that may interact to develop and maintain disrupted sleep. Based on the extant literature, parameters of the cancer and its treatment, physical and social environmental conditions both during and after treatment, changes to family behavior and norms, psychological factors and traumatic stress, and reduced physical activity are hypothesized to be the most pertinent risk factors for disrupted sleep in this population. Potential clinical assessment strategies and behavioral interventions relevant to these considerations are discussed, with reference to the behavioral model of insomnia. The review concludes by offering directions for research and clinical practice, including developing and testing comprehensive assessment tools, intervention effectiveness studies in both oncology and primary care clinics, and efforts to increase patient-provider communication about sleep in pediatric oncology.

Predictors of fatigue and poor sleep in adult survivors of childhood Hodgkin's lymphoma: a report from the Childhood Cancer Survivor Study

PURPOSE

Survivors of pediatric Hodgkin's lymphoma (HL) are at risk for a number of debilitating late effects. Excessive fatigue and poor sleep quality are primary complaints of HL survivors. Understanding the emotional and physical factors that influence fatigue and sleep quality may provide opportunities for intervention to improve health-related quality of life for HL survivors.

METHODS

Data from 751 adult survivors of childhood HL who participated in the Childhood Cancer Survivor Study (CCSS) from 2000-2002 were analyzed. Multivariable logistic regression analyses investigated the demographic, psychological, and physical variables that predicted clinically significant levels of poor sleep quality, fatigue, and excessive daytime sleepiness.

RESULTS

Survivors' self-reported level of emotional distress, pain, and physical functioning limitations did not differ from population norms. Clinically elevated levels of emotional distress (OR 8.38, 95% CI 4.28-16.42) and pain (OR 3.73, 95% CI 2.09-6.67) increased the risk for endorsing elevated levels of fatigue. Survivors with elevated levels of emotional distress (OR 6.83, 95% CI 2.71-15.90) and pain (OR 5.27, 95% CI 1.78-15.61) were more likely to report poor sleep quality. Pain (OR 2.11, 95% CI 1.39-3.34) was related to excessive daytime sleepiness.

CONCLUSIONS

Emotional and physical factors are associated with elevated levels of fatigue, excessive daytime sleepiness, and poor sleep quality in survivors of pediatric HL. This is consistent with findings from research conducted with non-cancer survivors.

IMPLICATIONS FOR CANCER SURVIVORS

These results suggest that interventions designed to target sleep and fatigue difficulties in the general population may be well suited for pediatric HL survivors as well.

Behavioral, Social, and Emotional Symptom Comorbidities and Profiles in Adolescent Survivors of Childhood Cancer: A Report From the Childhood Cancer Survivor Study

PURPOSE

In the general population, psychological symptoms frequently co-occur; however, profiles of symptom comorbidities have not been examined among adolescent survivors of childhood cancer.

PATIENTS AND METHODS

Parents of 3,893 5-year survivors of childhood cancer who were treated between 1970 and 1999 and who were assessed in adolescence (age 12 to 17 years) completed the Behavior Problems Index. Age- and sex-standardized z scores were calculated for symptom domains by using the Childhood Cancer Survivor Study sibling cohort. Latent profile analysis identified profiles of comorbid symptoms, and multivariable multinomial logistic regression modeling examined associations between cancer treatment exposures and physical late effects and identified symptom profiles. Odds ratios (ORs) and 95% CIs for latent class membership were estimated and analyses were stratified by cranial radiation therapy (CRT; CRT or no CRT).

RESULTS

Four symptoms profiles were identified: no significant symptoms (CRT, 63%; no CRT, 70%); elevated anxiety and/or depression, social withdrawal, and attention problems (internalizing; CRT, 31%; no CRT, 16%); elevated headstrong behavior and attention problems (externalizing; CRT, no observed; no CRT, 9%); and elevated internalizing and externalizing symptoms (global symptoms; CRT, 6%; no CRT, 5%). Treatment with ≥ 30 Gy CRT conferred greater risk of internalizing (OR, 1.7; 95% CI, 1.0 to 2.8) and global symptoms (OR, 3.2; 95% CI, 1.2 to 8.4). Among the no CRT group, corticosteroid treatment was associated with externalizing symptoms (OR, 1.9; 95% CI, 1.2 to 2.8) and ≥ 4.3 g/m(2) intravenous methotrexate exposure was associated with global symptoms (OR, 1.5; 95% CI, 0.9 to 2.4). Treatment late effects, including obesity, cancer-related pain, and sensory impairments, were significantly associated with increased risk of comorbid symptoms.

CONCLUSION

Behavioral, emotional, and social symptoms frequently co-occur in adolescent survivors of childhood cancer and are associated with treatment exposures and physical late effects. Assessment and consideration of symptom profiles are essential for directing appropriate mental health treatment for adolescent survivors.

[Pain experiences and life satisfaction of young adult cancer patients]

BACKGROUND

After having completed medical treatment cancer patients often suffer from pain that can impair the quality of life. While young adolescents and adults (AYA) with cancer have become the focus of research during recent years, literature on the prevalence, quality and relief of pain in AYA patients is lacking.

OBJECTIVE

This study investigated psychosocial data on pain experienced by AYA patients (e.g. prevalence, type, distress, anxiety and need for support) and the association with the quality of life.

MATERIAL AND METHODS

Standardized and validated questionnaires were used for assessing pain and quality of life in AYA patients defined as the patient group between 18 and 39 years. Calculated regression models were summarized in a pathway model.

RESULTS

Out of 117 AYA patients (66 % women) 45 (39 %) suffered from pain and of these 73 % felt impaired due to the pain, 58 (50 %) had a fear of pain and 21 (20 %) reported a need for support. The severity of pain had a negative influence on physical functioning (β = -0.335) and health-related satisfaction (β = -0.415). Regarding the quality of life, 105 patients (90 %) were overall satisfied with their life. Dissatisfaction was reported in the areas of occupation (39.34 %), ability to relax (36.31 %), physical performance (34.29 %), income (32.27 %) and partnership/sexuality (29.25 %).

CONCLUSION

This study provides evidence that pain plays a relevant role for AYA patients after the end of medical treatment. A substantial proportion of AYA patients reported the need for support so that the question arises whether medical pain management is sufficient, particularly as pain was associated with impairment and strongly negatively associated with health-related satisfaction.

Exploration of Morbidity in a Serial Study of Long-Term Brain Tumor Survivors: A Focus on Pain

PURPOSE

Children surviving brain tumors are frequently identified as having substantially decreased health-related quality of life (HRQL) in cross-sectional studies. This study explored the HRQL of a cohort of such survivors, who were recruited as adolescents and followed for a decade, in order to determine the trajectory of their morbidities.

METHOD

Children diagnosed between January 1, 1985, and December 31, 1998, more than 2 years from diagnosis (N = 40), were recruited in 2000/2001 (T1) aged 16.74 ± 4.23 years. Health Utilities Index questionnaires (HUI2/3) were completed in 2000/2001 and again at 5 years (T2) and 10 years (T3), with 37 and 25 participants then aged 21.54 ± 4.29 and 27.97 ± 4.07 years, respectively. In addition to study subjects, parental proxies completed questionnaires at T1 and T2, while study subjects selected proxies at T3. Single attributes (domains/dimensions) of HRQL and details of pain were analyzed.

RESULTS

Cognition was the attribute compromised most often (T1 = 66.7% of participants, T2 = 62.2%, T3 = 60.0%). Pain was also reported frequently (T1 = 35%, T2 = 25%, T3 = 52%), and at T3 correlated moderately with HUI2 sensation (0.77) and HUI3 vision (0.44), speech (0.51), and ambulation (0.50). The lower median utility score for pain at T3 than at T1/T2 was a clinically important difference. Severe pain was identified in the lower extremities, back, upper extremities, and abdomen. Morbidity was observed also in emotion (worry HUI2 and unhappiness HUI3), sensation, and vision.

CONCLUSION

Decreased HRQL in survivors of brain tumors in childhood is multifaceted. Pain is a prominent burden, along with morbidity in cognition, emotion, sensation, and vision. Further studies should explore pain and neurologic deficits, and potential opportunities for therapeutic intervention.

Development of the family symptom inventory: a psychosocial screener for children with hematology/oncology conditions

A growing body of literature has begun to underscore the importance of integrating family-based comprehensive psychological screening into standard medical care for children with oncology and hematology conditions. There are no known family-based measures designed to screen for clinically significant emotional and behavioral concerns in pediatric oncology and hematology patients. The aim of this study was to develop and evaluate the Family Symptom Inventory (FSI), a brief screener of patient and family member psychological symptoms. The FSI also screens for common comorbid physical symptoms (pain and sleep disturbance) and is designed for use at any point during treatment and follow-up. A total of 488 caregivers completed the FSI during regular hematology/oncology visits for 193 cancer, 219 sickle cell disease, and 76 hematology pediatric patients. Exploratory factor analysis, confirmatory factor analysis, and tests of reliability and preliminary validity were conducted. Exploratory factor analysis suggested a 34-item, 4-factor solution, which was confirmed in an independent sample using confirmatory factor analysis (factor loadings=0.49 to 0.88). The FSI demonstrated good internal reliability (α's=0.86 to 0.92) and good preliminary validity. Regular psychosocial screening throughout the course of treatment and follow-up may lead to improved quality of care for children with oncology and hematology conditions.

Oncologic pain relief: strategies told by adolescents with cancer

In view of the negative impact of pain on the quality of life of cancer patients, identifying and stimulating the use of effective strategies to minimize these painful feelings is highly relevant for care. The aim of this study was to identify painful experiences of adolescents with cancer and to get to know their strategies for pain relief. This is an exploratory research, using qualitative data analysis. Semistructured interviews were held with nine adolescents with cancer, who reported on acute, recurring and chronic, physical and emotional painful experiences. To relieve these pains, they described pharmacological and non-pharmacological strategies, including: distraction, presence of relatives, bed positioning, cooperation to accomplish procedures and keeping up positive thinking. Therefore, it is essential for health professionals to know available evidence for pain relief and to develop skills to articulate this knowledge with their professional experience and with the patients' own strategies.

How do follow-up care instructions and treatment summaries relate to cancer survivors' cancer-related pain?

CONTEXT

Cancer-related pain is a problem for many cancer survivors. Treatment summaries (TS) and follow-up care instructions (FCI) provided after cancer treatment could reduce pain for cancer survivors.

OBJECTIVES

This study sought to determine how TS and FCI received by cancer survivors relate to cancer survivors' cancer-related pain after treatment completion.

METHODS

Data were from 2010, Behavioral Risk Factor Surveillance System, Cancer Survivorship module, completed by 10 U.S. states and entities.

RESULTS

Pain was reported by 9% of survivors. TS (P = 0.02) and FCI (P < 0.001) were associated with pain. Compared with cancer survivors who had not received TS or FCI, those who received TS had greater odds of pain (odds ratio, 1.57; 95% confidence interval, 1.08-2.28) and those who received FCI had more than twice the odds of pain (odds ratio, 2.36; 95% confidence interval, 1.52-3.67).

CONCLUSION

FCI and TS were related to pain but in the opposite direction than predicted. Those who received TS and FCI were more likely to report pain than those who did not receive FCI and TS. This may be explained by the severity of cancer treatment. It is possible that those who undergo more severe cancer treatments are more likely to receive FCI and TS. Testing this relationship is a logical next step.

Headache types, related morbidity, and quality of life in survivors of childhood acute lymphoblastic leukemia: a prospective cross sectional study

BACKGROUND

Increased headache prevalence was recently reported in survivors of childhood ALL. Headache sub types, related morbidity, and effect on quality of life has not been reported thus far.

OBJECTIVE

To study headache prevalence and type, related disability, and quality of life in a cohort of childhood acute lymphoblastic leukemia (ALL) survivors.

METHODS

Childhood ALL survivors in at least 1-year of remission and 5 years from diagnosis completed questionnaires and were evaluated by a neurologist. Disability was evaluated with Pediatric Migraine Disability Assessment scale and the Short Form-36 Health Survey assessed quality of life.

RESULTS

Thirty nine of 72 (54%) females and 37 of 90 (41%) males reported headaches. Median time from ALL diagnosis to first headache was 5.2 years and median age at headache onset was 10.1 years in 76 participants with headache. Migraine headaches were diagnosed in 51 (31%) and episodic tension-type headaches in 49 (30%); migraine and tension-type headaches co-existed in 24 (15%) and 18 (11%) participants had chronic daily headaches. Fatigue was associated with migraine headache while hypertension and female gender associated with tension type headache. Headache-related disability was mild in 22 (29%), moderate in 7 (9%), and severe in 5 (7%) survivors, and was absent in the remaining 42 (55%) survivors with headache. Both migraine and tension type headaches associated with reduced mental component scores, while headache related disability associated with a reduced physical component scores.

CONCLUSIONS

Headaches are common in ALL survivors but only a minority has significant disability or impairment of quality of life.

Pain management at home in children with cancer: a daily diary study

BACKGROUND

With the transition of care of cancer patients from the hospital to the home setting, parents are largely responsible for children's pain management. Children's cancer pain is undermanaged, yet, there is little empirical data on the occurrence and management of cancer pain in the home setting. The purpose of the present study, therefore, was to employ a daily diary protocol to examine barriers to pain management of children's cancer pain by parents at home.

PROCEDURE

Parent-child dyads were recruited from the Cancer Institute at a major children's hospital in Southern California. A total of 45 patient/parent pairs completed baseline data on demographic and personality characteristics, children's quality of life, and parental beliefs regarding analgesic use for children and then completed daily diaries of pain and analgesic administration for 14 consecutive days.

RESULTS

Most children were reported to experience chronic pain while undergoing treatment for cancer, yet overall analgesic administration at home was low. Parents who reported misconceptions regarding analgesic use for children were less likely to administer pain medication to children. Children who were less shy, more social, or had lower quality of life were more likely to receive analgesics.

CONCLUSIONS

A significant proportion of children receiving outpatient treatment for cancer were rated as experiencing chronic pain and pain was not optimally managed in the home setting. Further understanding and addressing barriers to children's cancer pain management in the home setting will aid in alleviating unnecessary pain in this vulnerable patient population.

Emotional distress among adult survivors of childhood cancer

PURPOSE

The purposes of this study were to estimate the prevalence of emotional distress in a large cohort of adult survivors of childhood cancer and to evaluate the interrelationship of risk factors including cancer-related late effects.

METHODS

Adult survivors of childhood cancer (N = 1,863), median age of 32 years at follow-up, completed comprehensive medical evaluations. Clinically relevant emotional distress was assessed using the Brief Symptom Inventory 18 and was defined as T-scores ≥63. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using multivariable logistic regression models to identify risk factors for distress. Path analysis was used to examine associations among identified risk factors.

RESULTS

Elevated global distress was reported by 15.1% of survivors. Cancer-related pain was associated with elevated distress (OR 8.72; 95% CI, 5.32-14.31). Survivors who reported moderate learning or memory problems were more likely to have elevated distress than survivors who reported no learning or memory problems (OR 3.27; 95% CI, 2.17-4.93). Path analysis implied that cancer-related pain has a direct effect on distress symptoms and an indirect effect through socioeconomic status and learning or memory problems. Similar results were observed for learning or memory problems.

CONCLUSIONS

Childhood cancer-related morbidities including pain and learning or memory problems appear to be directly and indirectly associated with elevated distress symptoms decades after treatment. Understanding these associations may help inform intervention targets for survivors of childhood cancer experiencing symptoms of distress.

IMPLICATIONS FOR CANCER SURVIVORS

A subset of long-term childhood cancer survivors experience significant emotional distress. Physical and cognitive late effects may contribute to these symptoms.

Psychological and behavioral approaches to cancer pain management

This review examines evidence for psychological factors that affect pain across the cancer continuum from diagnosis through treatment and long-term survivorship or end of life. Evidence is convincing that emotional distress, depression, anxiety, uncertainty, and hopelessness interact with pain. Unrelieved pain can increase a desire for hastened death. Patients with cancer use many strategies to manage pain, with catastrophizing associated with increased pain and self-efficacy associated with lower pain reports. A variety of psychological and cognitive behavioral treatments can reduce pain severity and interference with function, as indicated in multiple meta-analyses and high-quality randomized controlled trials. Effective methods include education (with coping skills training), hypnosis, cognitive behavioral approaches, and relaxation with imagery. Exercise has been tested extensively in patients with cancer and long-term survivors, but few exercise studies have evaluated pain outcomes. In survivors post-treatment, yoga and hypnosis as well as exercise show promise for controlling pain. Although some of these treatments effectively reduce pain for patients with advanced disease, few have been tested in patients at the end of life. Given the clear indicators that psychological factors affect cancer pain and that psychological and behavioral treatments are effective in reducing varying types of pain for patients with active disease, these methods need further testing in cancer survivors post-treatment and in patients with end-stage disease. Multidisciplinary teams are essential in oncology settings to integrate analgesic care and expertise in psychological and behavioral interventions in standard care for symptom management, including pain.

Pain in cancer survivors

Pain is a common problem in cancer survivors, especially in the first few years after treatment. In the longer term, approximately 5% to 10% of survivors have chronic severe pain that interferes with functioning. The prevalence is much higher in certain subpopulations, such as breast cancer survivors. All cancer treatment modalities have the potential to cause pain. Currently, the approach to managing pain in cancer survivors is similar to that for chronic cancer-related pain, pharmacotherapy being the principal treatment modality. Although it may be appropriate to continue strong opioids in survivors with moderate to severe pain, most pain problems in cancer survivors will not require them. Moreover, because more than 40% of cancer survivors now live longer than 10 years, there is growing concern about the long-term adverse effects of opioids and the risks of misuse, abuse, and overdose in the nonpatient population. As with chronic nonmalignant pain, multimodal interventions that incorporate nonpharmacologic therapies should be part of the treatment strategy for pain in cancer survivors, prescribed with the aim of restoring functionality, not just providing comfort. For patients with complex pain issues, multidisciplinary programs should be used, if available. New or worsening pain in a cancer survivor must be evaluated to determine whether the cause is recurrent disease or a second malignancy. This article focuses on patients with a history of cancer who are beyond the acute diagnosis and treatment phase and on common treatment-related pain etiologies. The benefits and harms of the various pharmacologic and nonpharmacologic options for pain management in this setting are reviewed.

Treatment of chronic pain in children and adolescents

SUMMARY Chronic pain in children is a poorly recognized entity that is challenging to treat and leaves many families frustrated. Often, lack of an identifiable etiology along with the complex biopsychosocial nature of this condition leads to a lengthy diagnostic odyssey and delayed treatment that exacerbates the existing problem. Effective treatment of chronic pain requires a team approach in order to deal with the various aspects of this condition. Combinations of medication along with nonpharmacologic treatments, such as physical therapy, psychological interventions and complementary therapies, are often the most effective ways of treating chronic pain rather than medication alone. Further research is needed to understand the complex biobehavioral processes involved in the development and maintenance of chronic pain. Development of targeted novel therapies as well as comparative studies of existing treatments will help to improve treatment for chronic pain in children.

A smartphone-based pain management app for adolescents with cancer: establishing system requirements and a pain care algorithm based on literature review, interviews, and consensus

BACKGROUND

Pain that occurs both within and outside of the hospital setting is a common and distressing problem for adolescents with cancer. The use of smartphone technology may facilitate rapid, in-the-moment pain support for this population. To ensure the best possible pain management advice is given, evidence-based and expert-vetted care algorithms and system design features, which are designed using user-centered methods, are required.

OBJECTIVE

To develop the decision algorithm and system requirements that will inform the pain management advice provided by a real-time smartphone-based pain management app for adolescents with cancer.

METHODS

A systematic approach to algorithm development and system design was utilized. Initially, a comprehensive literature review was undertaken to understand the current body of knowledge pertaining to pediatric cancer pain management. A user-centered approach to development was used as the results of the review were disseminated to 15 international experts (clinicians, scientists, and a consumer) in pediatric pain, pediatric oncology and mHealth design, who participated in a 2-day consensus conference. This conference used nominal group technique to develop consensus on important pain inputs, pain management advice, and system design requirements. Using data generated at the conference, a prototype algorithm was developed. Iterative qualitative testing was conducted with adolescents with cancer, as well as pediatric oncology and pain health care providers to vet and refine the developed algorithm and system requirements for the real-time smartphone app.

RESULTS

The systematic literature review established the current state of research related to nonpharmacological pediatric cancer pain management. The 2-day consensus conference established which clinically important pain inputs by adolescents would require action (pain management advice) from the app, the appropriate advice the app should provide to adolescents in pain, and the functional requirements of the app. These results were used to build a detailed prototype algorithm capable of providing adolescents with pain management support based on their individual pain. Analysis of qualitative interviews with 9 multidisciplinary health care professionals and 10 adolescents resulted in 4 themes that helped to adapt the algorithm and requirements to the needs of adolescents. Specifically, themes were overall endorsement of the system, the need for a clinical expert, the need to individualize the system, and changes to the algorithm to improve potential clinical effectiveness.

CONCLUSIONS

This study used a phased and user-centered approach to develop a pain management algorithm for adolescents with cancer and the system requirements of an associated app. The smartphone software is currently being created and subsequent work will focus on the usability, feasibility, and effectiveness testing of the app for adolescents with cancer pain.

Survivors of childhood and adolescent cancer: life-long risks and responsibilities

Survival rates for most paediatric cancers have improved at a remarkable pace over the past four decades. In developed countries, cure is now the probable outcome for most children and adolescents who are diagnosed with cancer: their 5-year survival rate approaches 80%. However, the vast majority of these cancer survivors will have at least one chronic health condition by 40 years of age. The burden of responsibility to understand the long-term morbidity and mortality that is associated with currently successful treatments must be borne by many, including the research and health care communities, survivor advocacy groups, and governmental and policy-making entities.

Association between the prevalence of symptoms and health-related quality of life in adult survivors of childhood cancer: a report from the St Jude Lifetime Cohort study

PURPOSE

We investigated the association between prevalence of symptoms and health-related quality of life (HRQOL) in adult survivors of childhood cancer enrolled in the St Jude Lifetime Cohort study.

METHODS

Eligibility criteria include childhood malignancy treated at St Jude, survival ≥ 10 years from diagnosis, and current age ≥ 18 years. Study participants were 1,667 survivors (response rate = 65%). Symptoms were self-reported by using a comprehensive health questionnaire and categorized into 12 classes: cardiac; pulmonary; motor/movement; pain in head; pain in back/neck; pain involving sites other than head, neck, and back; sensation abnormalities; disfigurement; learning/memory; anxiety; depression; and somatization. HRQOL was measured by using physical/mental component summary (PCS/MCS) and six domain scores of the Medical Outcomes Study 36-Item Short-Form Health Survey. Multivariable regression analysis was performed to investigate associations between symptom classes and HRQOL. Cumulative prevalence of symptom classes in relation to time from diagnosis was estimated.

RESULTS

Pain involving sites other than head, neck and back, and disfigurement represented the most frequent symptom classes, endorsed by 58.7% and 56.3% of survivors, respectively. Approximately 87% of survivors reported multiple symptom classes. Greater symptom prevalence was associated with poorer HRQOL. In multivariable analysis, symptom classes explained up to 60% of the variance in PCS and 56% of the variance in MCS; demographic and clinical variables explained up to 15% of the variance in PCS and 10% of the variance in MCS. Longer time since diagnosis was associated with higher cumulative prevalence in all symptom classes.

CONCLUSION

A large proportion of survivors suffered from many symptom classes, which was associated with HRQOL impairment.

Screening tool for late-effect pediatric neuro-oncological clinics: a treatment-oriented questionnaire

BACKGROUND

Many survivors of pediatric brain tumors (SPBTs) suffer from long-term late effects (LEs). Our aim was to create a practical screening tool for detecting LEs in this population. Such a screening tool will improve our ability to identify those patients who may benefit from treatment in LE clinics while focusing on individual relevant issues.

PROCEDURE

We developed the Treatment-Oriented Screening Questionnaire (TOSQ); a self-reported, risk-based questionnaire that addresses all LEs SPBTs can potentially suffer. As a basis for the TOSQ design we used the Long-Term Follow-Up Guidelines published by the Children's Oncology Group. Output includes individual recommendations for further treatment. We prospectively assessed whether the TOSQ can accurately detect treatment targets in SPBTs by comparing patient and caregiver questionnaire scores with physician evaluations. Data are presented from 41 SPBTs.

RESULTS

The TOSQ is a precise screening tool for identifying LEs in SPBTs based on the significant correlation (P < 0.05) that was found between parental scores and physician evaluations. Statistical testing proved that parents are a good source of information about child's health status, and that TOSQ accurately reflects the correlation between patient difficulties and quality of life.

CONCLUSIONS

The TOSQ is the first described screening tool for identification of LEs designed specifically for SPBTs. It is simple to use and provides a valid, comprehensive and economic assessment followed by targeted treatment plan for each patient. By repeatedly using the TOSQ over the years, we can improve our ability to detect and give focused treatment to those who require assistance.

Screening for pain in pediatric brain tumor survivors using the pain thermometer

Numerous instruments have been developed to measure pain within various populations; however, there remains limited understanding of how these tools are applicable to childhood cancer survivors. This study compared a single-item screening measure, the Pain Thermometer (PT), with a more in-depth measure, the Brief Pain Survey (BPS), in a cohort of childhood brain tumor survivors. Ninety-nine survivors (aged 13-32 years) with a median time from diagnosis of 9.9 years (range = 2-18 years) completed the 2 instruments. Thirty-seven survivors (37.4%) were identified on the BPS as having clinically significant pain, but the PT was not found to be an accurate tool for identifying these pain cases. Application of receiver operating characteristic curve analysis of PT ratings against BPS criterion indicated overall concordance between measures. No cutoff score on the PT were identified that resulted in acceptable sensitivity, meaning pain cases identified on the BPS would be missed on the PT. Findings suggest that a multi-item screening measure may better identify clinically significant pain in childhood brain tumor survivors compared with a 1-item screening measure alone.

Prevalence and predictors of prescription psychoactive medication use in adult survivors of childhood cancer: a report from the Childhood Cancer Survivor Study

PURPOSE

Childhood cancer survivors are at risk for late effects which may be managed pharmacologically. The purposes of this study were to estimate and compare the prevalence of psychoactive medication use of adult survivors of childhood cancer and sibling controls, identify predictors of medication use in survivors, and investigate associations between psychoactive medications and health-related quality of life (HRQOL).

METHODS

Psychoactive medication use from 1994 to 2010 was evaluated in 10,378 adult survivors from the Childhood Cancer Survivor Study. A randomly selected subset of 3,206 siblings served as a comparison group. Multivariable logistic regression models were used to calculate odds ratios (OR) for baseline and new onset of self-reported psychoactive medication use and HRQOL.

RESULTS

Survivors were significantly more likely to report baseline (22 vs. 15 %, p < 0.001) and new onset (31 vs. 25 %, p < 0.001) psychoactive medication use compared to siblings, as well as use of multiple medications (p < 0.001). In multivariable models, controlling for pain and psychological distress, female survivors were significantly more likely to report baseline and new onset use of antidepressants (OR = 2.66, 95 % CI = 2.01-3.52; OR = 2.02, 95 % CI = 1.72-2.38, respectively) and multiple medications (OR = 1.80, 95 % CI = 1.48-2.19; OR = 1.77, 95 % CI = 1.48-2.13, respectively). Non-cranial radiation and amputation predicted incident use of analgesics >15 years following diagnosis. Antidepressants were associated with impairment across all domains of HRQOL, with the exception of physical function.

CONCLUSIONS

Prevalence of psychoactive medication use was higher among survivors for most medication classes, as was the use of multiple medications. Clinicians should be aware of the possible contribution of psychoactive medications to HRQOL.

IMPLICATIONS FOR CANCER SURVIVORS

Survivors of childhood cancer are more likely to be prescribed psychoactive medication than their sibling counterparts, though use of such medication does not appear to normalize quality of life. Survivors are encouraged to consider additional interventions, including psychosocial support and physical exercise.
