Agin-Liebes GI, Malone T, Yalch MM, Mennenga SE, Ponte KL, Guss J, et al. Long-term follow-up of psilocybin-assisted psychotherapy for psychiatric and existential distress in patients with life-threatening cancer. J Psychopharmacol 2020 Feb;34(2):155-166 PMID 31916890
BACKGROUND: A recently published randomized controlled trial compared single-dose psilocybin with single-dose niacin in conjunction with psychotherapy in participants with cancer-related psychiatric distress. Results suggested that psilocybin-assisted psychotherapy facilitated improvements in psychiatric and existential distress, quality of life, and spiritual well-being up to seven weeks prior to the crossover.

Barrett FS, Doss MK, Sepeda ND, Pekar JJ, Griffiths RR. Emotions and brain function are altered up to one month after a single high dose of psilocybin. Sci Rep 2020 Feb 10;10(1):2214-020-59282-y PMID 32042038
Psilocybin is a classic psychedelic compound that may have efficacy for the treatment of mood and substance use disorders. Acute psilocybin effects include reduced negative mood, increased positive mood, and reduced amygdala response to negative affective stimuli. However, no study has investigated the long-term, enduring impact of psilocybin on negative affect and associated brain function. Read more here.
Baydoun M, Barton DL, Peterson M, Wallner LP, Visovatti MA, Arslanian-Engoren C, et al. Yoga for Cancer-Related Fatigue in Survivors of Hematopoietic Cell Transplantation: A Feasibility Study. J Pain Symptom Manage 2020 Mar;59(3):702-708 PMID 31765760
CONTEXT: Cancer-related fatigue (CRF) is one of the most common symptoms experienced by cancer patients after hematopoietic cell transplantation (HCT). Yoga is an approach with supportive evidence to improve CRF in different cancer populations, but to our knowledge, it has not been tested in an adult HCT population. OBJECTIVES: The aim of this study was to evaluate the feasibility of a yoga intervention offered to adult HCT survivors with moderate-to-severe CRF. METHODS: This feasibility study used a single-arm, pretest-posttest design. Adult HCT survivors were enrolled in a six-week restorative yoga intervention that consisted of a one-hour once-weekly class with twice-weekly home practice using a DVD. RESULTS: Twenty participants (13 women and seven men) enrolled in this study with a mean age of 51 years (SD = 12.5). The sample consisted of 19 allogeneic HCT survivors, seven of whom had a history of acute graft-vs.-host disease (GVHD), six with active, extensive chronic GVHD, and one autologous HCT survivor. The accrual acceptance rate was 23.2% (20/86 HCT survivors) and retention rate was 60% (12/20). Overall adherence was 45.4%. No adverse events were reported. CONCLUSION: The results of this study suggest that a restorative yoga intervention in adult HCT survivors is safe and feasible. The incidence of GVHD may have impacted adherence. Strategies to improve accrual acceptance, retention, and adherence are needed.
Beeler WH, Bellile EL, Casper KA, Jaworski E, Burger NJ, Malloy KM, et al. Patient-reported financial toxicity and adverse medical consequences in head and neck cancer. Oral Oncol 2020 Feb;101:104521 PMID 31877502
OBJECTIVES: Financial toxicity (FT) is a significant barrier to high-quality cancer care, and patients with head and neck cancer (HNCA) are particularly vulnerable given their need for intensive support, daily radiotherapy (RT), and management of long-term physical, functional, and psychosocial morbidities following treatment. We aim to identify predictors of FT and adverse consequences in HNCA following RT. MATERIALS AND METHODS: We performed a prospective survey study of patients with HNCA seen in follow-up at an academic comprehensive cancer center (CCC) or Veterans Affairs hospital between 05/2016 and 06/2018. Surveys included validated patient-reported functional outcomes and the COST measure, a validated instrument for measuring FT. RESULTS: The response rate was 86% (n = 63). Younger age and lower median household income by county were associated with lower COST scores (i.e., worse FT) on multivariable analysis (p = .045 and p = .016, respectively). Patients with worse FT were more likely to skip clinic visits (RR (95% CI) 2.13 (1.23-3.67), p = .007), be noncompliant with recommended supplements or medications (1.24 (1.03-1.48), p = .02), and require supportive infusions (1.10 (1.02-1.20), p = .02). At the CCC, patients with worse FT were more likely to require feeding tubes (1.62 (1.14-2.31), p = .007). Overall, 36% reported that costs were higher than expected, 48% were worried about paying for treatment, and 33% reported at least a moderate financial burden from treatment. CONCLUSION: HNCA patients experience substantial FT from their diagnosis and/or therapy, with potential implications for medical compliance, QOL, and survivorship care.
Bienemann B, Ruschel NS, Campos ML, Negreiros MA, Mograbi DC. Self-reported negative outcomes of psilocybin users: A quantitative textual analysis. PLoS One 2020 Feb 21;15(2):e0229067 PMID 32084160
Psilocybin, a substance mainly found in mushrooms of the genus psilocybe, has been historically used for ritualistic, recreational and, more recently, medicinal purposes. The scientific literature suggests low toxicity, low risk of addiction, overdose, or other causes of injury commonly caused by substances of abuse, with growing interest in the use of this substance for conditions such as treatment-resistant depression. However, the presence of negative outcomes linked to psilocybin use is not clear yet. The objective of this study is to investigate the negative effects of psilocybin consumption, according to the users' own perception through self-reports extracted from an online platform.

Chien TJ, Liu CY, Fang CJ, Kuo CY. The maintenance effect of acupuncture on breast cancer-related menopause symptoms: a systematic review. Climacteric 2020 Apr;23(2):130-139 PMID 31612733
Background: Acupuncture has been used for many breast cancer treatment-related problems, but how long the effect lasts is unknown. This meta-analysis aims to evaluate how long the effect of acupuncture on breast cancer-related hot flushes and menopause symptoms lasts.Methods: The research design followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement, without language restrictions. Seven databases from inception through February 2019 were accessed; only randomized clinical trials (RCTs) that examined the maintenance effect of acupuncture on hot flushes or menopause symptoms after treatment were included. Cochrane criteria were followed and RevMan 5.2 software was used to analyze trials.Results: In total, 943 patients from 13 RCTs were analyzed. The meta-analysis showed that acupuncture had no significant long-term maintenance effect on the frequency or severity of hot flushes (p = 0.29; p = 0.34), but had a significant 3-month maintenance effect of ameliorating menopause symptoms at 3 months after treatment ended (p = 0.001). No adverse events were reported.Conclusions: Acupuncture significantly alleviated menopause symptoms for at least 3 months, but not hot flushes. Breast cancer patients concerned about the adverse effects of hormone therapy could consider acupuncture as an alternative. Additional acupuncture at 3 months after the initial treatment course could be considered. A large-scale study may help to define the optimal guideline for this issue.
Compen F, Adang E, Bisseling E, van der Lee M, Speckens A. Cost-utility of individual internet-based and face-to-face Mindfulness-Based Cognitive Therapy compared with treatment as usual in reducing psychological distress in cancer patients. Psychooncology 2020 Feb;29(2):294-303 PMID 31650662
OBJECTIVE: It was previously determined that group-based face-to-face Mindfulness-Based Cognitive Therapy (MBCT) and individual internet-based MBCT (eMBCT) are equally efficacious compared with treatment as usual (TAU) in reducing psychological distress. In this study, the incremental cost-utility of both interventions compared with TAU was assessed. Read more here.
Jagielski CH, Tucker DC, Dalton SO, Mrug S, Wurtzen H, Johansen C. Personality as a predictor of well-being in a randomized trial of a mindfulness-based stress reduction of Danish women with breast cancer. J Psychosoc Oncol 2020 Jan-Feb;38(1):4-19 PMID 31267818
Purpose: Many clinical interventions have been designed to improve psychological well-being in women with breast cancer; however, there are individual differences in the extent of benefit across participants. Mindfulness-Based Stress Reduction (MBSR) is a structured 8-week intervention that has been shown to reduce depression and anxiety for patients with breast cancer. Personality factors may influence which participants benefit more from various psychological interventions, including MBSR.Design: In a secondary analysis, we examined whether personality factors accounted for variability in response to an MBSR intervention for women with breast cancer.Sample: Two hundred eighty Danish women with breast cancer who completed the Mindfulness and Cancer Mamma trial were included in this analysis.Methods: Using multiple regression analyses, we investigated whether personality factors, measured by the NEO-PI-R, contribute independently or interact with treatment to predict depressive symptoms at 2, 6, and 12-month follow-up.Findings: The interaction between low conscientiousness and MBSR, as well as high neuroticism and MBSR each predicted significantly lower levels of distress at 12-month follow-up compared to women who higher in conscientious or lower in neuroticism.Conclusions: Personality factors may contribute to the impact of psychosocial interventions, such as MBSR, on psychological well-being.Implications for Psychosocial Providers: Utilizing personality measures may assist providers in identifying which patients may benefit from mindfulness therapies.
Lewis CR, Preller KH, Braden BB, Riecken C, Vollenweider FX. Rostral Anterior Cingulate Thickness Predicts the Emotional Psilocybin Experience. Biomedicines 2020 Feb 18;8(2):10.3390/biomedicines8020034 PMID 32085521
Psilocybin is the psychoactive compound of mushrooms in the psilocybe species. Psilocybin directly affects a number of serotonin receptors, with highest affinity for the serotonin 2A receptor (5HT-2Ar). Generally, the effects of psilocybin, and its active metabolite psilocin, are well established and include a range of cognitive, emotional, and perceptual perturbations. Despite the generality of these effects, there is a high degree of inter-individual variability in subjective psilocybin experiences that are not well understood. Others have shown brain morphology metrics derived from magnetic resonance imaging (MRI) can predict individual drug response. Due to high expression of serotonin 2A receptors (5HT-2Ar) in the cingulate cortex, and its prior associations with psilocybin, we investigate if cortical thickness of this structure predicts the psilocybin experience in healthy adults.

Mertens LJ, Wall MB, Roseman L, Demetriou L, Nutt DJ, Carhart-Harris RL. Therapeutic mechanisms of psilocybin: Changes in amygdala and prefrontal functional connectivity during emotional processing after psilocybin for treatment-resistant depression. J Psychopharmacol 2020 Feb;34(2):167-180 PMID 31941394
BACKGROUND: Psilocybin has shown promise as a treatment for depression but its therapeutic mechanisms are not properly understood. In contrast to the presumed actions of antidepressants, we recently found increased amygdala responsiveness to fearful faces one day after open-label treatment with psilocybin (25 mg) in 19 patients with treatment-resistant depression, which correlated with treatment efficacy. AIMS: Aiming to further unravel the therapeutic mechanisms of psilocybin, the present study extends this basic activation analysis. We hypothesised changed amygdala functional connectivity, more precisely decreased amygdala-ventromedial prefrontal cortex functional connectivity, during face processing after treatment with psilocybin.

Milian L, Mata M, Alcacer J, Oliver M, Sancho-Tello M, Martin de Llano JJ, et al. Cannabinoid receptor expression in non-small cell lung cancer. Effectiveness of tetrahydrocannabinol and cannabidiol inhibiting cell proliferation and epithelial-mesenchymal transition in vitro. PLoS One 2020 Feb 12;15(2):e0228909 PMID 32049991
BACKGROUND/OBJECTIVE: Patients with non-small cell lung cancer (NSCLC) develop resistance to antitumor agents by mechanisms that involve the epithelial-to-mesenchymal transition (EMT). This necessitates the development of new complementary drugs, e.g., cannabinoid receptors (CB1 and CB2) agonists including tetrahydrocannabinol (THC) and cannabidiol (CBD). The combined use of THC and CBD confers greater benefits, as CBD enhances the effects of THC and reduces its psychotropic activity. We assessed the relationship between the expression levels of CB1 and CB2 to the clinical features of a cohort of patients with NSCLC, and the effect of THC and CBD (individually and in combination) on proliferation, EMT and migration in vitro in A549, H460 and H1792 lung cancer cell lines.

Purpose: To assess the feasibility, safety, and preliminary effectiveness of a 12-week multimodal Qigong Mind-Body Exercise (QMBE) program for breast cancer survivors with persistent post-surgical pain (PPSP). Methods: This was a single-arm mixed-methods pilot study. Primary outcome measures were feasibility (recruitment, adherence) and safety. Validated self-report questionnaires were used to evaluate a constellation of interdependent symptoms, including pain, fatigue, mood, exercise, interoceptive awareness, and health-related quality of life at baseline and 12 weeks. A subset of the instruments was administered 6 months postintervention. Shoulder range of motion and grip strength were objectively assessed at baseline and 12 weeks. Qualitative interviews were conducted at baseline and 12 weeks. Read more here.
Samuels N, Ben-Arye E. Integrative Approaches to Chemotherapy-Induced Peripheral Neuropathy. Curr Oncol Rep 2020 Feb 11;22(3):23-020-0891-2 PMID 32048067
PURPOSE OF REVIEW: Chemotherapy-induced peripheral neuropathy (CIPN) is a common complication of cancer treatment, with conventional treatment limited in its ability for prevention or treatment of symptoms. This review addresses the research assessing the effectiveness and safety of complementary and integrative medicine (CIM) in preventing and treating CIPN-related symptoms. RECENT FINDINGS: The CIM modalities acupuncture, classical massage, omega-3 fatty acids, and the Japanese Kampo medicine Goshanjishen may be of benefit in preventing or treating CIPN. Vitamin E (alpha-tocopherol), glutamine/glutamate, alpha-lipoic acid, and acetyl-L-carnitine (ALCAR) are not, with ALCAR increasing symptom severity and vitamin E the risk for developing prostate cancer. CIM therapies with a potential for preventing or treating CIPN-related symptoms should be further investigated. CIM is considered safe when provided within an integrative oncology setting, under the guidance and supervision of an integrative physician.
Teo I, Vilardaga JP, Tan YP, Winger J, Cheung YB, Yang GM, et al. A feasible and acceptable multicultural psychosocial intervention targeting symptom management in the context of advanced breast cancer. Psychooncology 2020 Feb;29(2):389-397 PMID 31703146
OBJECTIVE: Advanced breast cancer patients around the world experience high symptom burden (ie, distress, pain, and fatigue) and are in need of psychosocial interventions that target symptom management. This study examined the feasibility, acceptability, and engagement of a psychosocial intervention that uses cognitive-behavioral strategies along with mindfulness and values-based activity to enhance patients' ability to manage symptoms of advanced disease in a cross-cultural setting (United States and Singapore). Pre-treatment to post-treatment outcomes for distress, pain, and fatigue were compared between intervention recipients and waitlisted controls. METHODS: A pilot randomized controlled trial included women with advanced breast cancer (N = 85) that were recruited in the United States and Singapore. Participants either received the four session intervention or be put on waitlist. Descriptive statistics and effect size of symptom change were calculated. RESULTS: The psychosocial intervention was found to be feasible as indicated through successful trial accrual, low study attrition (15% ), and high intervention adherence (77% completed all sessions). Acceptability (ie, program satisfaction and cultural sensitivity) and engagement to the study intervention (ie, practice of skills taught) were also high. Anxiety, depression, and fatigue scores remained stable or improved among intervention participants while the same symptoms worsened in the control group. In general, effect sizes are larger in the US sample compared with the Singapore sample. CONCLUSIONS: The cognitive-behavioral, mindfulness, and values-based intervention is feasible, acceptable, and engaging for advanced breast cancer patients in a cross-cultural setting and has potential for efficacy. Further larger-scaled study of intervention efficacy is warranted.
Voiss P, Hoxtermann MD, Dobos G, Cramer H. Mind-body medicine use by women diagnosed with breast cancer: results of a nationally representative survey. Support Care Cancer 2020 Mar;28(3):1077-1082 PMID 31187251
PURPOSE: Worldwide breast cancer is the most commonly diagnosed cancer in women and often associated with a profound physiological stress reaction. Mind-body medicine modalities have been proven effective in reducing stress symptoms. This article will cover the prevalence of MBM use in women with and without breast cancer in the US population and detect predictors of MBM use in women diagnosed with breast cancer. METHODS: The 2017 National Health Interview Survey (NHIS) was used to study the prevalence of breast cancer and the use of mind-body medicine (MBM) among individuals with breast cancer in the US population. Using chi-squared tests and backward stepwise multiple logistic regression analyses, predictors of MBM use in women with breast cancer in the past 12 months were identified. RESULTS: The prevalence of breast cancer in women was 3.1%. Among women diagnosed with breast cancer, 25.2% had used MBM in the past 12 months. Spiritual meditation (14.3%), followed by yoga (9.6%), and mindfulness meditation (4.3%) were the most commonly used MBM approaches for women with breast cancer diagnosis. Only higher education independently predicted the use of MBM among them. CONCLUSIONS: In this nationally representative sample of the USA, the most common used MBM approach was spiritual meditation, while this approach is much less researched than the evidence based approaches of yoga and mindfulness meditation. Especially stressed individuals worldwide could benefit from MBM the literature suggests. Particularly in the acute survivorship stage, influencing the initial stress reaction could be beneficial.
Xie C, Dong B, Wang L, Jing X, Wu Y, Lin L, et al. Mindfulness-based stress reduction can alleviate cancer- related fatigue: A meta-analysis. J Psychosom Res 2020 Mar;130:109916 PMID 31927347
OBJECTIVES: The purpose of this meta-analysis was to critically evaluate the effects of mindfulness-based stress reduction (MBSR) on cancer-related fatigue (CRF). METHODS: A systematic search of eight databases (Web of Science, Pubmed, Cochrane Library, Spring link, CNKI, Wanfang, VIP, CBM) was performed, to find randomized controlled trials (RCTs) from inception to January 2019. Using Cochrane Collaboration criteria, two reviewers critically and independently assessed the risk of bias and extracted correlated data using the designed form. All analyses were performed with Review Manager 5.3. RESULTS: In all, fifteen RCTs were included in the systematic review, fourteen of which, consisting of 3008 patients (MBSR, 1502; control, 1506), were included in the meta-analysis. MBSR had a significant effect on fatigue in cancer patients, particularly among lung cancer patients. The meta-analysis also indicated that MBSR could significantly mitigate CRF compared with usual care or no intervention. 8 weeks of MBSR, supervised by experts, had a large effect on CRF. CONCLUSIONS: MBSR is effective for CRF management and can be recommended as a beneficial complementary therapy for CRF patients.
Yoon SL, Grundmann O, Williams JJ, Wu SS, Leeuwenburgh C, Huo Z, et al. Differential response to targeted acupuncture by gender in patients with gastrointestinal cancer cachexia: secondary analysis of a randomized controlled trial. Acupunct Med 2020 Feb;38(1):53-60 PMID 31544469
BACKGROUND: Cancer cachexia (CC) is a significant contributor to mortality and morbidity in patients with gastrointestinal (GI) cancer. Treatment options to prevent or halt the progression of CC are limited. Targeted acupuncture (TA) was used in GI patients with CC to evaluate for a potential gender effect. PATIENTS AND METHODS: Participants (n = 30) were recruited from two outpatient clinics in the northern central part of Florida. All participants were diagnosed with CC and GI cancers. A randomized, single-blind, placebo-controlled clinical trial was used to compare TA to non-targeted acupuncture (NTA) over the course of 8 weeks. Primary endpoints were weight and body composition changes measured by bioelectrical impedance analysis (BIA) and biomarker analysis (tumor necrosis factor (TNF)-alpha and leptin). Herein, gender differences across and within TA and NTA groups were examined as a secondary analysis. RESULTS: A significant (p = 0.026) interaction between weight and gender was noted, which manifested in a non-significant increase in the male intervention (MI) group, while TNF-alpha levels significantly increased by gender (p = 0.028) and group (p = 0.006) over the course of the study. All other groups either lost or did not change weight. The extracellular-to-intracellular water (ECW/ICW) ratio was significantly elevated for the TA group (p = 0.02) and for males (p = 0.009) at completion of the study. TNF-alpha and leptin levels were positively correlated within the MI group at the end of the study. CONCLUSION: A decrease in leptin in the MI group corresponded to higher appetite and weight gain. The elevated ECW/ICW ratio indicates an inflammatory response in the MI group. This gender-specific response may be based on hormone-specific regulation of food intake. Further studies with larger sample sizes are required to support the results.
Zimmaro LA, Carson JW, Olsen MK, Sanders LL, Keefe FJ, Porter LS. Greater mindfulness associated with lower pain, fatigue, and psychological distress in women with metastatic breast cancer. Psychooncology 2020 Feb;29(2):263-270 PMID 31509614
OBJECTIVE: Women with metastatic breast cancer (MBC) report high levels of disease-related symptoms including pain, fatigue, psychological distress, and sleep disturbance. Mindfulness may be particularly relevant to women with MBC given the high symptom burden and psychological toll of this disease; however, the topic is understudied among this patient population. Therefore, we aimed to test the associations between mindfulness and patient-reported symptoms among a sample of women with MBC. METHODS: Sixty-four women with MBC completed baseline questionnaires of mindfulness (Five Facet Mindfulness Questionnaire-Short Form [FFMQ-SF]) and symptoms of pain severity and interference, fatigue, psychological distress, and sleep disturbance as part of a randomized controlled trial of a Mindful Yoga intervention. Correlational analyses of data collected at baseline tested associations between the five mindfulness facets (observing, describing, acting with awareness, nonjudging, and nonreactivity) and patient-reported measures of symptoms. RESULTS: Overall, higher mindfulness was associated with lower symptom levels including lower pain severity, pain interference, fatigue, anxiety, depression, and sleep disturbance. However, degree of association varied by mindfulness facet. Nonreactivity, nonjudging, and describing showed the most frequent associations and largest effect sizes across symptoms, while observing showed the least frequent associations and lowest effect sizes. CONCLUSIONS: Mindfulness-and in particular nonreactivity, nonjudging, and describing-may be a personal resource for women with MBC in coping with complex symptoms of this life-threatening illness. Findings are discussed relative to their implications for interventions aimed at increasing mindfulness in this vulnerable population.
