Critical review of complementary therapies in haemato-oncology

Effect of non-pharmacological interventions on symptoms and quality of life in patients with hematological malignancies - A systematic review

BACKGROUND

Non-pharmacological interventions have the potential to enhance health-related quality of life (HRQoL) through symptom management. This systematic review aims to identify, collate, and assess randomized controlled trials investigating the effect of non-pharmacological interventions on symptoms and HRQoL within hematology.

METHODS

MEDLINE/PUBMED, EMBASE, CINAHL, PSYCINFO and COCHRANE were searched up to April 2021. Outcomes were changes in symptoms and HRQoL.

RESULTS

Sixty-five studies were categorized into five intervention types: Mind/body (n=9), Web-based (n=9), Music/art (n=6), Consultation-based (n=4), and Physical activity (n=37). We found significantly reduced fatigue (n=12 studies), anxiety (n=8) and depression (n=7), with 11 studies showing significant improvements in HRQoL.

CONCLUSIONS

The evidence for non-pharmacological interventions shows substantial variation in efficacy and methodological quality. While specific symptoms and HRQoL outcomes significantly favored the intervention, no particular intervention can be emphasized as more favorable, given the inability to conduct a meta-analysis.

An oasis in the hospital: the perceived benefits of a cancer support center in a hospital setting offering complementary therapies

AIMS

The aim of this study was to explore and describe the experiences of persons attending a cancer support center, providing emotional support to cancer patients through self-selected complementary therapies offered free of charge through qualified volunteer therapists. A grounded theory methodology was used. Sources of data were 16 semistructured interviews with persons attending the center. Interviews were digitally recorded and transcribed verbatim. Analysis was conducted using the constant comparative method.

FINDINGS

The overarching theme that emerged in this study was the benefits attributed to attendance at the cancer support center. The center was described as an "oasis" in the hospital, and three aspects relating to this were identified: (a) facilitating comfort, (b) increasing personal control, and (c) helping make sense of the cancer experience.

CONCLUSION

A drop-in center offering complementary therapies appeared to enable coping with the diagnosis and treatment of cancer by facilitating comfort and increasing perceptions of personal control. The center also helped some participants to make sense of their experience with cancer. This research has provided a unique insight into the ongoing emotional needs of cancer patients, and directions for further development and research into the provision of holistic care for patients within a hospital setting.

Gentle Massage Improves Disease- and Treatment-Related Symptoms in Patients with Acute Myelogenous Leukemia

OBJECTIVE

Cancer treatment is reported to be stressful, and patients diagnosed with hematologic cancers often exhibit higher levels of anxiety and emotional distress than individuals with other malignancies. Management of these symptoms in patients with hematologic cancer presents significant challenges, as many of them are in and out of the hospital while undergoing high dose chemotherapy. Oncology patients use complementary modalities such as therapeutic massage in an attempt to alleviate disease and treatment-related symptoms, including anxiety and emotional distress. In the current study, the feasibility of a novel massage intervention delivered over the continuum of care, as well as assessment of the immediate and cumulative effects of massage, was examined in patients with acute myelogenous leukemia.

METHODS

A mixed-methods, unmasked, prospective, randomized study was conducted with two groups: a usual care alone control group and a massage therapy intervention plus usual care group.

RESULTS

Significant improvements in levels of stress and health-related quality of life were observed in the massage therapy group versus the usual care alone group, after adjusting for anxiety level, including both immediate and cumulative effects of massage.

CONCLUSIONS

While the findings of the current study regarding acceptability, feasibility, and potential efficacy of therapeutic massage as a complementary health-enhancing intervention in patients diagnosed with acute myelogenous leukemia are very promising, the relatively small size of the study sample limits generalizability.

Association of distress symptoms and use of complementary medicine among patients with cancer

AIMS AND OBJECTIVES

The aim of this study was to investigate the association between distress symptoms and the types of complementary and alternative medicine use in patients with cancer.

BACKGROUND

Patients diagnosed with cancer have increasingly turned to the use of complementary and alternative medicine to manage its symptoms and cope with the side effects of conventional treatment.

DESIGN

A descriptive cross-sectional study.

METHODS

A face-to-face interview using a structured questionnaire was conducted with 208 outpatients at a medical centre in central Taiwan. The questionnaire included questions on socio-demographic information, disease specifics, distress symptoms and complementary and alternative medicine usage in the past 12 months. Logistic regression analysis was used to assess the association between distress symptoms and the use of different complementary and alternative medicine modalities.

RESULTS

A total of 165 (79·3%) patients reported use of at least one complementary and alternative medicine modality during the past 12 months. Complementary and alternative medicine users and non-users were not significantly different in age, sex, marital status, education level, religious affiliation and disease-related variables. Fatigue (66·8%) was the most frequently reported symptoms and was significantly associated with complementary and alternative medicine use (OR = 14·11, p = 0·001). Regarding specific complementary and alternative medicine modalities, chanting and enzyme therapy were found to be associated with 13 (68·4%) of the 19 distress symptoms.

CONCLUSIONS

There was no association between complementary and alternative medicine use and demographic or disease-related variables. Complementary and alternative medicine was widely used by patients with cancer, and symptom of fatigue was most strongly associated with complementary and alternative medicine use. Chanting and enzyme therapy were the two most frequently used complementary and alternative medicine modalities that were significantly associated with the 19 distress symptoms.

RELEVANCE TO CLINICAL PRACTICE

Health care providers should ask their patients about their complementary and alternative medicine use to avoid possible adverse interactions between conventional treatment and complementary and alternative medicine interventions, in particular, those remedies that are likely to interact with cancer medications.

How many cancer patients use complementary and alternative medicine: a systematic review and metaanalysis

BACKGROUND

No comprehensive systematic review has been published since 1998 about the frequency with which cancer patients use complementary and alternative medicine (CAM).

METHODS

MEDLINE, AMED, and Embase databases were searched for surveys published until January 2009. Surveys conducted in Australia, Canada, Europe, New Zealand, and the United States with at least 100 adult cancer patients were included. Detailed information on methods and results was independently extracted by 2 reviewers. Methodological quality was assessed using a criteria list developed according to the STROBE guideline. Exploratory random effects metaanalysis and metaregression were applied.

RESULTS

Studies from 18 countries (152; >65 000 cancer patients) were included. Heterogeneity of CAM use was high and to some extent explained by differences in survey methods. The combined prevalence for "current use" of CAM across all studies was 40%. The highest was in the United States and the lowest in Italy and the Netherlands. Metaanalysis suggested an increase in CAM use from an estimated 25% in the 1970s and 1980s to more than 32% in the 1990s and to 49% after 2000.

CONCLUSIONS

The overall prevalence of CAM use found was lower than often claimed. However, there was some evidence that the use has increased considerably over the past years. Therefore, the health care systems ought to implement clear strategies of how to deal with this. To improve the validity and reporting of future surveys, the authors suggest criteria for methodological quality that should be fulfilled and reporting standards that should be required.

Acupuncture May Stimulate Anticancer Immunity via Activation of Natural Killer Cells

This article presents the hypothesis that acupuncture enhances anticancer immune functions by stimulating natural killer (NK) cells. It provides background information on acupuncture, summarizes the current scientific understanding of the mechanisms through which NK cells act to eliminate cancer cells, and reviews evidence that acupuncture is associated with increases in NK cell quantity and function in both animals and humans. The key contribution of this article involves the use of cellular immunology and molecular biological theory to interpret and synthesize evidence from disparate animal and human studies in formulating the 'acupuncture immuno-enhancement hypothesis': clinicians may use acupuncture to promote the induction and secretion of NK-cell activating cytokines that engage specific NK cell receptors that endogenously enhance anticancer immune function.

Methodological reflections on body-mind intervention studies with cancer patients

OBJECTIVE

Methodological reflection on the content, results and limitations of three body-mind intervention studies with cancer patients (CPs) in order to improve the quality of studies on body-mind interventions and to raise the potential value for CPs.

METHODS

A secondary analysis of a study on haptotherapy and two studies applying relaxing face massage, using a variety of well-being effect measures. Six methodological themes are discussed: (1) drop-out; (2) characteristics of participating patients, (3) participation of patients in other complementary interventions; (4) satisfaction of participants; (5) effects of the three interventions, and (6) role of response shift.

RESULTS

The three interventions showed limited effects after controlling for relevant confounding factors. They are mainly the small sample sizes, the low intensity of the intervention, the possible inadequate measure moments and the use of other CAM that may be responsible for the absence of effects.

CONCLUSIONS

Body-mind interventions require more methodological reflections to develop attractive and effective interventions for CPs. Attention needs to be paid to measuring short term effects, practically fitting research designs, and response shift.

PRACTICE IMPLICATIONS

Interventions should be intensive, repeated and not too short. The implementation of interventions requires attention to several organizational factors in the health care.

Trick or treat? Australian newspaper portrayal of complementary and alternative medicine for the treatment of cancer

PURPOSE

Many cancer patients within developed nations cite the media as informing their decisions to use complementary and alternative medicine (CAM). The present study describes (1) Australian newspaper coverage of CAM use for cancer between 1998 and 2007; (2) trends in reporting frequency and characteristics; and (3) how the Australian press framed stories on CAM use for cancer.

MATERIALS AND METHODS

This study is a content analysis featuring quantitative and qualitative techniques, the latter guided by 'media framing', of targeted newspaper articles.

RESULTS

One hundred nineteen articles focused on CAM use for the treatment of cancer were identified. Quantitative analysis found that biologically based CAMs were most frequently described and breast cancer most mentioned. Two thirds of all articles described CAM use in the context of a cure, with approximately half of these opposing this reason for use. Potential benefits of CAM were discussed more frequently than potential risks, and information on costs and how to access CAM were uncommon. Recommendations included advice to use complementary, not alternative therapies, yet advice to discuss CAM with a medical doctor was rare. Qualitative analysis found six CAM cancer-related frames, four in support of CAM use for cancer treatment. The dominant frame constructed CAM as legitimate tools to assist biomedicine (even to cure), with others depicting CAM as normal and necessary or as addressing limitations of biomedicine. Negative frames depicted CAM as questionable and risky practices and the industry/practitioners as possessing malevolent intent.

CONCLUSION

These findings have implications for biomedical practitioners attempting to determine, respect and assist patient choices about their treatment.

Rationales for CAM Education in Health Professions Training Programs

The authors review the use of complementary and alternative medicine (CAM) in the United States. They then present and discuss the rationales used by the 15 National Center for Complementary and Alternative Medicine CAM educational grantees in their original proposals for incorporating CAM content into conventional health professions training programs. Fourteen of the grantees were from major U.S. medical and nursing schools, and one was from a medical student foundation. Awards were for five-year periods (with the exception of one three-year grant) from 2000 to 2008. Rationales for developing educational programs about CAM for conventional health professionals included (1) the prevalence and growth of CAM in the United States, (2) response to governmental, legislative, and other mandates, (3) need for enhanced communication between conventional providers and patients using CAM, (4) need to enhance safety of CAM use and interactions with conventional care, (5) CAM education's positive impact on broadening core competencies for conventional health care professionals, (6) positive impact on enhancing cultural competency, (7) need for better communication between conventional and CAM providers, (8) potential for improving health care coordination, (9) potential impact on increasing CAM research quality and capacity, and (10) potential for enhancing quality of care through informed CAM use. Integration of CAM with conventional health care requires educational venues that prepare conventionally trained caregivers with a sufficient knowledge base for assessing beneficial and detrimental interactions between CAM and conventional care approaches; development of criteria for making informed referrals to CAM practitioners; and enhanced research capacity.
