Complementary Therapies and Childhood Cancer

Global Use of Traditional and Complementary Medicine in Childhood Cancer: A Systematic Review

Purpose

Traditional and complementary medicine (T&CM) strategies are commonly used in pediatric oncology. Patterns may vary based on country income. We systematically reviewed published studies describing T&CM use among pediatric oncology patients in low-income countries (LIC/LMIC), middle-income countries (UMIC), and high-income countries (HIC). Objectives included describing estimated prevalence of use, reasons for use, perceived effectiveness, modalities used, rates of disclosure, and reporting of delayed or abandoned treatment.

Methods

MEDLINE, EMBASE, Global Health, CINAHL, PsycINFO, Allied and Complementary Medicine Database, Cochrane Database of Systematic Reviews, and ProceedingsFirst were searched. Inclusion criteria were primary studies involving children younger than the age of 18 years, undergoing active treatment of cancer, and any T&CM use. Exclusion criteria included no pediatric oncology–specific outcomes and studies involving only children off active treatment. Data were extracted by two reviewers using a systematic data extraction form determined a priori.

Results

Sixty-five studies published between 1977 and 2015 were included, representing 61 unique data sets and 7,219 children from 34 countries. The prevalence of T&CM use ranged from 6% to 100%. Median rates of use were significantly different in LIC/LMIC (66.7% ± 19%), UMIC (60% ± 26%), and HIC (47.2% ± 20%; P = .02). Rates of disclosure differed significantly by country income, with higher median rates in HIC. Seven studies reported on treatment abandonment or delays.

Conclusion

The use of T&CM in pediatric oncology is common worldwide, with higher median prevalence of use reported in LIC/LMIC. Further research is warranted to examine the impact on treatment abandonment and delay.

Characteristics of Traditional Chinese Medicine Use in Pediatric Cancer Patients: A Nationwide, Retrospective, Taiwanese-Registry, Population-Based Study

BACKGROUND

Large-scale surveys of complementary traditional Chinese medicine (TCM) use in pediatric cancer patients are lacking. The aim of our study was to investigate the use of TCM in pediatric cancer patients.

METHODS

We analyzed cancer patients younger than 18 years (n = 12 965) who were registered in the National Health Insurance Research Database in Taiwan between 2001 and 2011. Patients were categorized into TCM or non-TCM users based on their use of TCM.

RESULTS

In Taiwan, 8086 (62.4%) children with cancer sought TCM treatment at some point. Children in older age groups, including school-aged children and adolescents, were more likely to use TCM. There was no significant difference in the distributions of gender and urbanization. The 3 most common diseases for which TCM users visited the clinic were neoplasm (33.2%), respiratory system disease (32.9%), and infectious disease (8.86%). The most commonly utilized TCM therapy was Chinese herbal remedies. Patients who had comorbid conditions such as allergic rhinitis, dyspepsia, disorders of menstruation, and disease of the musculoskeletal system and connective tissue tended to visit TCM clinics.

CONCLUSIONS

Adjunctive TCM use is not low in Taiwanese children with cancer. Further studies to investigate the efficacy and safety of TCM in children with cancer are warranted.

Use of complementary and alternative medicine among children, adolescent, and young adult cancer survivors: a survey study

PURPOSE

The main objective of this study was to investigate the prevalence of complementary and alternative medicine (CAM) use, types and reasons for use, and determinants of use among survivors of childhood cancer.

METHODS

An interviewer-based survey of CAM use was administered to 197 survivors or their guardians. Demographic data, CAM therapies used, purpose and referral for use, and communication about use was collected.

RESULTS

A total of 115 (58%) survivors reported using CAM in survivorship, 72% of which used biologically based therapies. The majority of therapies were used for relaxation and stress management (15%), referred for use by the parent (25%), reported as very effective (62%), and initiated 0 to 4 years after completion of cancer treatment (41%). Among CAM users, young adults used manipulative and body-based therapies [odds ratio (OR)=3.3; 95% confidence interval (CI), 1.4-7.8] and mind-body therapies (OR=2.8, 95% CI: 1.2-6.4) more than children. Use of mind-body therapies was associated with not attending religious services regularly (OR=2.4; P<0.01). Half (51%) of all CAM therapies were disclosed to the physician.

CONCLUSIONS

Survivors of childhood cancer frequently use CAM for health promotion and mitigation of physical and psychological conditions. Clinicians should consider the role of CAM in the adoption of healthy lifestyles among this population.

Cancer patient disclosure and patient-doctor communication of complementary and alternative medicine use: a systematic review

OBJECTIVE

To explore the nondisclosure of complementary and alternative medicine (CAM) use among cancer patients, including reasons for and outcomes from nondisclosure of CAM use, within the context of patient-doctor communication.

METHOD

A systematic review was conducted exploring investigations surrounding the communication of CAM use for patients with cancer published until August 2011.

RESULTS

A total of 21 studies were located, which reported a prevalence of CAM use among patients with cancer ranging between 11% and 95%; of these patients, 20% to 77% did not disclose their CAM use. The main reasons for nondisclosure were the doctor's lack of inquiry; patient's anticipation of the doctor's disapproval, disinterest, or inability to help; and patient's perception that disclosure of CAM use is irrelevant to their conventional care. There is some evidence to suggest that patient-doctor communication about the use of CAM was associated with an enhanced patient-doctor relationship and higher patient satisfaction.

CONCLUSIONS

Although the use of CAM by patients with cancer is high, patients frequently fail to disclose its use to their health professionals for reasons emanating from both sides of the dyadic patient-doctor relationship. Because a substantial proportion of patients with cancer may use CAM and there is potential for herb- or vitamin-drug interactions, further research in patient-doctor communication about CAM is necessary to maintain patient safety and wellbeing. The development of effective interventions to improve the disclosure of CAM use should be an integral part of this future research.

Complementary and alternative medicine use in children with thalassaemia

AIMS AND OBJECTIVES

The aims of this study were to: (1) determine the types of complementary and alternative medicine use among children with thalassaemia as reported by parents and (2) describe sociodemographic and medical factors associated with the use of such treatments in families residing in southern Turkey.

BACKGROUND

Thalassaemia is one of the most common human genetic diseases. Despite the therapeutic efforts, patients will encounter a variety of physical and psychological problems. Therefore, the use of complementary and alternative medicines among children thalassaemia is becoming increasingly popular.

DESIGN

This is a descriptive study of complementary and alternative medicine.

METHODS

This study was conducted in the Hematology Outpatient Clinic at Akdeniz University Hospital and in the Thalassemia Centre at Ministry of Health Antalya Education and Research Hospital, Antalya, Turkey, between January 2010-December 2010. Parents of 97 paediatric patients, among 125 parents who applied to the haematology outpatient clinic and thalassaemia centre between these dates, agreed to take part in the study with whom contact could be made were included. Data were collected by using a questionnaire.

RESULTS

The proportion of parents who reported using one or more of the complementary and alternative medicine methods was 82·5%. Of these parents, 61·8% were using prayer/spiritual practice, 47·4% were using nutritional supplements and 35·1% were using animal materials.

CONCLUSION

It was determined that a significant portion of the parents using complementary and alternative medicine use it to treat their children's health problems, they were informed about complementary and alternative medicine by their paediatricians and family elders, and they have discussed the use of complementary and alternative medicine with healthcare professionals.

RELEVANCE TO CLINICAL PRACTICE

To sustain medical treatment and prognosis of thalassaemia, it is important for nurses to consult with their patients and parents regarding the use and potential risks of some complementary and alternative medicine.

Prevalence of complementary medicine use in pediatric cancer: a systematic review

CONTEXT

Complementary and alternative medicine (CAM) is used by pediatric patients with cancer, but the actual frequency of CAM use is undetermined.

OBJECTIVE

In this systematic review we summarize the current evidence on the prevalence of CAM use in pediatric patients with cancer and assess the reported quality of included studies.

METHODS

We systematically searched 6 major electronic databases, reference lists of existing reviews, and personal files. We included full articles about primary research studies (without language restriction) that reported the prevalence of CAM use if all or a defined subsample of participants were pediatric patients with cancer. Detailed information regarding methods and results was extracted from the original articles. A quality-assessment tool was rigorously developed on the basis of the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement and used to assess reported study quality. Formal tests of interrater agreement were conducted.

RESULTS

We included 28 studies with survey data (collected from 1975 to 2005) from 3526 children. In 20 studies with 2871 participants, the prevalence of any CAM use (since cancer diagnosis) ranged from 6% to 91%; considerable heterogeneity across studies precluded meta-analysis. Study quality was mixed and not correlated with CAM prevalence. Herbal remedies were the most popular CAM modality, followed by diets/nutrition and faith-healing. Commonly reported reasons for CAM use included to help cure or fight the child's cancer, symptomatic relief, and support of ongoing use of conventional therapy. There was little evidence of an association between CAM use and patients' sociodemographic characteristics.

CONCLUSIONS

Many pediatric patients with cancer use CAM. It is important that pediatricians be aware of this fact and encourage open communication with patients and their parents. Using standardized survey methods and CAM definitions in future studies could improve their quality and help generate comparable data. Our quality-assessment tool could prove valuable for other reviews of prevalence studies.

Parental attitudes toward acupuncture in a community sample

OBJECTIVES

The primary objective of this study was to investigate parental attitudes toward acupuncture for their child. No known research has explored how medical providers discuss acupuncture with families or specific concerns parents have about acupuncture. This study examined whether acupuncture attitudes were influenced by (1) the way acupuncture is explained to parents by a physician and (2) parental experience with acupuncture.

DESIGN

Parents (N = 240) read vignettes that varied in a 2 (Physician Description of Acupuncture: Traditional Chinese Medicine versus biomedical) x 2 (Gender: male versus female) design and responded to questions assessing their attitudes toward acupuncture.

RESULTS

A factor analysis of the vignette questions resulted in two factors: acupuncture acceptability (alpha = 0.88) and information seeking (alpha = 0.70). Previous experience with acupuncture significantly increased acupuncture acceptability and reduced interest in information seeking. Parents with experience were more likely to report wanting to pursue acupuncture for their child. A biomedical explanation led to increased acceptability and interest in pursuing information among parents with experience (d = 0.36), and significantly predicted parental agreement with the vignette item, "I would have my child receive acupuncture treatment." Common acupuncture concerns included fear of needles and acupuncture ineffectiveness.

CONCLUSIONS

Parents' experience with acupuncture, regardless of its perceived helpfulness, appears to play an important role in their consideration of acupuncture for their child. Additional research is needed to fully understand the importance of the way acupuncture is presented to families, as it appears to impact parental attitudes in subtle ways. Parents have numerous concerns regarding acupuncture. Our findings suggest that providers would benefit from increased awareness of families' interest in and use of complementary and alternative medicine so as to better monitor safety, provide advice, and discuss treatment expectations and misconceptions.

Integrative therapies for children with hematological malignancies

Evidence for integrative therapies (IT) in children with hematological malignancies is slowly evolving. The ideal model of integrative pediatric oncology would offer IT modalities that are deemed safe and effective in conjunction with effective conventional medical treatments. Because of potential interactions, herbs and other dietary supplements should be used with caution, especially during active therapy. Health and wellness should be the emphasis, with IT therapies supporting health promotion and key disease prevention strategies for childhood cancer survivors. All uses, responses, and effects of IT therapies should be carefully documented. A desire to use IT therapies may be an effort to become an active participant in the healing process. Health care providers should encourage, not discourage, this partnership.

Massage therapy for children with cancer

This pilot study aimed to determine the feasibility of providing massage to children with cancer to reduce symptoms in children and anxiety in parents. Twenty-three children/parent dyads were enrolled; 17 completed all data points. Children with cancer, ages 1 to 18 years, received at least 2 identical cycles of chemotherapy, and one parent, participated in the 2-period crossover design in which 4 weekly massage sessions alternated with 4 weekly quiet-time control sessions. Changes in relaxation (heart and respiratory rates, blood pressure, and salivary cortisol level) and symptoms (pain, nausea, anxiety, and fatigue) were assessed in children; anxiety and fatigue were measured in parents. Massage was more effective than quiet time at reducing heart rate in children, anxiety in children less than age 14 years, and parent anxiety. There were no significant changes in blood pressure, cortisol, pain, nausea, or fatigue. Children reported that massage helped them feel better, lessened their anxiety and worries, and had longer lasting effects than quiet time. Massage in children with cancer is feasible and appears to decrease anxiety in parents and younger children.

Complementary and alternative medicine use in children with cancer and general and specialty pediatrics

The objective of this survey is to determine the frequency, reasons, and factors influencing use of complementary and alternative medicine (CAM) in general and specialty pediatrics within the same geographic area. Of the 281 surveys completed, CAM use was higher in children with epilepsy (61.9%), cancer (59%), asthma (50.7%), and sickle cell disease (47.4%) than in general pediatrics (36%). Children most often used prayer (60.5%), massage (27.9%), specialty vitamins (27.2%), chiropractic care (25.9%), and dietary supplements (21.8%). Parents who used CAM for themselves (68.7%) were more likely to access CAM for their child. Most parents (62.6%) disclosed some or all of their child's use of CAM to providers. This study confirms that within the same geographic region, children with chronic and life-threatening illness use more CAM therapies than children seen in primary care clinics. Children with cancer use CAM for different reasons than children with non-life-threatening illnesses.

Use of complementary and alternative medicine by pediatric patients with functional and organic gastrointestinal diseases: results from a multicenter survey

OBJECTIVES

Many pediatric patients use complementary and alternative medicine, especially when facing a chronic illness for which treatment options are limited. So far, research on the use of complementary and alternative medicine in patients with functional gastrointestinal disease has been scarce. This study was designed to assess complementary and alternative medicine use in children with different gastrointestinal diseases, including functional disorders, to determine which factors predicted complementary and alternative medicine use and to assess the willingness of parents to participate in future studies on complementary and alternative medicine efficacy and safety.

PATIENTS AND METHODS

The prevalence of complementary and alternative medicine use was assessed by using a questionnaire for 749 children visiting pediatric gastroenterology clinics of 9 hospitals in the Netherlands. The questionnaire consisted of 35 questions on the child's gastrointestinal disease, medication use, health status, past and future complementary and alternative medicine use, reasons for its use, and the necessity of complementary and alternative medicine research.

RESULTS

In this study population, the frequency of complementary and alternative medicine use was 37.6%. A total of 60.3% of this group had used complementary and alternative medicine specifically for their gastrointestinal disease. This specific complementary and alternative medicine use was higher in patients with functional disorders than organic disorders (25.3% vs 17.2%). Adverse effects of allopathic medication, school absenteeism, age <or=11 years, and a low effect of conventional treatment were predictors of specific complementary and alternative medicine use. Almost all (93%) of the parents considered it important that pediatricians initiate complementary and alternative medicine research, and 51% of parents were willing to participate in future complementary and alternative medicine trials.

CONCLUSIONS

Almost 40% of parents of pediatric gastroenterology patients are turning to complementary and alternative medicine for their child. Lack of effectiveness of conventional therapy, school absenteeism, and adverse effects of allopathic medication are more important predictors of complementary and alternative medicine use than the type of gastrointestinal disease. Because evidence on most complementary and alternative medicine modalities in children with gastrointestinal disorders is lacking, there is an urgent need for research in this field.

Complementary and alternative therapy use in adult survivors of childhood cancer: a report from the Childhood Cancer Survivor Study

BACKGROUND

Little information is available on the use of complementary and alternative medicine (CAM) in long-term survivors of childhood and adolescent cancer.

PROCEDURE

The Childhood Cancer Survivor Study (CCSS) is a resource evaluating the long-term effects of cancer and associated therapies in 5-year survivors of childhood and adolescent cancer diagnosed between 1970 and 1986 before the age of 21 years. A survey of CAM use during the previous year was distributed in 2000-2001 and completed by 9,984 survivors and 2,474 sibling controls.

RESULTS

CAM use reporting was similar in cases (39.4%) and siblings (41.1%). Compared to female siblings, female survivors were more likely to use biofeedback (odds ratio (OR) = 3.3; 95% CI = 1.0-10.8) and hypnosis/guided imagery (OR = 3.2; 95% CI = 1.6-6.8); male survivors were more likely than male siblings to use herbal remedies (OR = 1.3; 95% CI = 1.1-1.6). Factors associated with CAM use in survivors included elevated scores on the brief symptom inventory (BSI)-18 (OR = 1.6; 95% CI = 1.3-1.9), prolonged pain (OR = 1.5; 95% CI = 1.3-1.7), and having seen a physician in the past 2 years (OR = 1.6; 95% CI = 1.4-1.8). Survivors reporting low alcohol intake and excellent or good general health reported lower levels of CAM use (OR = 0.7; 95% CI = 0.7-0.8 and OR = 0.8; 95% CI = 0.7-0.9, respectively).

CONCLUSIONS

Survivors have a similar reported use of CAM compared to a sibling cohort. However, our data suggest that survivors turn to CAM for specific symptoms related to previous diagnosis and treatment. Future research is needed to determine whether CAM use reflects unmet health needs in this population.

Factors influencing complementary and alternative medicine use in a multisite pediatric oncology practice

PURPOSE

Complementary and alternative medicine (CAM) use in children is common although estimates of prevalence vary widely. We studied CAM use in our multisite pediatric oncology practice and evaluated factors influencing CAM use.

PATIENTS AND METHODS

We conducted an anonymous cross-sectional survey of 274 parents of children treated at the combined Nemours oncology practice in Florida and Delaware. Prevalence of CAM use was determined and binary logistic regression was used to evaluate factors related to CAM use in children.

RESULTS

The prevalence of CAM use among children and parents was 24.5% and 66.7%, respectively. Intensity of parent's use of CAM and geographic region were significantly associated with CAM use in children. The odds of CAM use in children increased with increasing use among parents. When parents used 6 or more therapies children were 33 times more likely to use CAM compared with those whose parents did not use CAM (odds ratio=33.3; 95% confidence interval, 10.4-106.2, P<0.01). Children in Florida were more likely to use CAM compared with children in Delaware (odds ratio=3.0; 95% confidence interval, 1.6-5.8, P<0.01).

CONCLUSIONS

These results indicate that children's use of CAM is significantly related to the intensity of parent's use regardless of parent's race, sex, education, household income, or child's sex or age. Clinicians should consider parental use and intensity of CAM use. Assessing CAM use should include classifications established by the National Center for CAM and a standard format for inquiring about CAM use should be developed.

Prevalence and characteristics of complementary medicine used by pediatric cancer patients in a mixed western and middle-eastern population

Complementary alternative medicine (CAM) usage and physicians' attitude was evaluated by interviewing all 100 pediatric cancer patients' parents and adolescents seen in the last half of 2003 at Meyer Children's Hospital in Israel. Sixty-one percent of the patients used CAM, an average of 3 different treatments per patient. CAM use was higher: among parents having previous CAM experience (85% vs. 51%, P=0.001) and higher education (79% vs. 50%, P=0.024), and in nonreligious families (71% vs. 50%). Jews and Arabs had similar CAM use rates as with different types of therapies. Socioeconomic status does not affect the rate of CAM use (P=0.9) but does affect the type of treatments used: patients of the higher socioeconomic level mainly used chemi-biological remedies and homeopathy (24% and 28% of interviewees; P=0.002). Middle or lower socioeconomic patients mostly used traditional Arab treatments (32% and 54%, respectively; P=0.012). Only 36% discussed it with their physicians, and most discussions were initiated by parents (79%). Beneficial effect was reported by 69% of CAM users. Most interviewees were interested in getting CAM information and availability in the hospital. Most pediatric cancer patients, regardless of their ethnic origin, use CAM without informing their physicians. Physicians should be aware and know more about it, to be advisors for better integrated care.
