Adverse events associated with complementary and alternative medicine use in ovarian cancer patients

Phytotherapy and Drugs: Can Their Interactions Increase Side Effects in Cancer Patients?

BACKGROUND

The use of herbs to treat illnesses was common in all historical eras. Our aim was to describe the phytotherapeutic substances that cancer patients use most commonly, and to determine whether their use can increase side effects.

METHODS

This was a retrospective and descriptive study conducted among older adults actively undergoing chemotherapy, admitted at the Oncology DH Unit (COES) of the Molinette Hospital AOU Città della Salute e della Scienza in Turin (Italy). Data collection was conducted through the distribution of self-compiled and closed-ended questionnaires during chemotherapy treatment.

RESULTS

A total of 281 patients were enrolled. Evaluating retching and sage consumption was statistically significant in multivariate analysis. The only risk factor for dysgeusia was chamomile consumption. Ginger, pomegranate, and vinegar use were retained as mucositis predictors.

CONCLUSIONS

Phytotherapeutic use needs more attention in order to decrease the risks of side effects, toxicity, and ineffective treatment. The conscious administration of these substances should be promoted for safe use and to provide the reported benefits.

A Systematic Review of Systematic Reviews and a Pooled Meta-Analysis on Complementary and Integrative Medicine for Improving Cancer-Related Fatigue

PURPOSE

Evidence supporting complementary and integrative medicine (CIM) for improving cancer-related fatigue (CRF) is still fragmented. This study therefore critically appraised all the systematic reviews (SRs) regarding the effectiveness of CIM in mitigating CRF in adults.

METHODS

A systematic review of SRs and a meta-analysis were conducted in 4 databases. The effect sizes of the included SRs were quantitatively pooled (standardized mean difference [SMD]; 95% CI) using a random-effects model. Heterogeneity was tested by using χ² (Q) tests and I² statistics.

FINDINGS

Twenty-two SRs met the inclusion criteria, and results from 20 SRs underwent meta-analysis. The pooled significant estimate of fatigue reduction was as follows: SMD, -0.50; 95% CI, -0.67 to -0.32; P < 0.001. The subgroup analysis based on the type of CIM intervention revealed that the approach showing higher effects in reducing fatigue thus far is acupuncture: SMD, -0.99; 95% CI = -1.37 to -0.62, P < 0.001; I² = 84%. CIM therapies showed a significant reduction of fatigue in patients with breast cancer: SMD, -0.46; 95% CI, -0.69 to -0.23; P < 0.001; I² = 82%.

IMPLICATIONS

CIM interventions showed effectiveness in reducing CRF. Subgroup analysis suggested some potential influencing, such as tumor type and specific CIM therapy factors, that require in-depth assessment in future research. Study protocol registration: PROSPERO CRD42020194254.

The Vitamin E Isoform α-Tocopherol is Not Effective as a Complementary Treatment in Cancer Treatment: A Systematic Review

The term vitamin E describes tocopherols and tocotrienols, whose chemical variations result in different biological activities including antioxidants. Neuroprotective effects of alpha-tocopherol against different toxins are assumed, therefore, it is discussed as a possible protective factor for adverse effects in cancer treatment. In July 2020, a systematic search was conducted searching five databases (Embase, Cochrane, PsychInfo, Cinahl, Medline) to find studies concerning the impact of α-tocopherol application and its potential harm on cancer patients. From 7546 search results, 22 publications referring to 20 studies with 1941 patients were included. Included patients were diagnosed with various cancer types and stages. Outcome variables were overall survival of cancer, symptom management of mucositis and chemotherapy-induced peripheral neuropathy (CIPN). The studies had different methodological qualities (mainly acceptable) and reported heterogeneous results: some reported significant improvement of mucositis and CIPN while others did not find changes concerning these endpoints. Due to heterogeneous results and methodical limitations of the included studies, a clear statement regarding the effectiveness of α-tocopherol as complementary treatment for cancer patients is not possible. Despite findings regarding reduction of oral side effects, usage of α-tocopherol during therapy must be discouraged because of potential negative influence on survival rates.

A Hierarchy of Healing: Origins of the Therapeutic Order and Implications for Research

The philosophy, principles, and theories of naturopathic medicine include the six Principles of Naturopathic Medicine and the Therapeutic Order. Together these constructs, describe the core principles of the practice of naturopathic medicine, as established by thought leaders throughout the formation and development of the profession. The naturopathic medicine research agenda (NMRA) set forth recommendations for the codification of the foundational theories of naturopathic medical practice. The "Therapeutic Order, Whole-systems, Evidence-based Research Standards" (TOWERS) initiative is proposed with the primary objective to conduct the rigorous evaluation of the Principles of Naturopathic Medicine and the Therapeutic Order constructs. It is envisioned that this initiative will result in the development of an evidence-base concerning the clinical theory, philosophy and principles of whole-systems naturopathic medicine. After over one hundred years of professional organization and formal practice, there is a need to translate these empirically derived constructs into an evidence-informed theory of naturopathic medicine.

Introduction to complementary, alternative, and traditional therapies

The use of complementary, alternative, and traditional therapies is increasing in the United States, and patients and their families are bringing these practices into the acute care setting. Acute and critical care nurses are in a unique and trusted position to advocate for their patients and to promote safe incorporation of complementary, alternative, and traditional therapies into the plan of care.

Appropriate use of complementary and alternative medicine approaches in gynecologic cancers

OPINION STATEMENT

Gynecologic cancer patients frequently desire alternative and/or complementary interventions or medicines to aid in relief of both cancer-related and treatment-related side effects. Furthermore, women also seek treatment to aid in superior outcomes and cure rates. Unfortunately, evidence suggests that the use of complementary and/or alternative medicine (CAM) is underreported or not discussed with physicians providing cancer care. In gynecologic cancer literature, there is a lack of scientific evidence either supporting or negating CAM. Because of the lack of information available, health care providers do not have good information regarding safety, efficacy, and dose of CAM. This leads to miscommunication or absence of communication between providers and patients. Because patients do use CAM to improve quality of life (QOL) during and after treatment, it would be educational for providers to know the specific QOL deficits among patients that require attention. Thus, with the ultimate goal of improving QOL for gynecologic cancer patients, providers should be pushed to investigate CAM and determine an honest support or rejection of these therapies.
