Preliminary Efficacy and Safety of Reishi & Privet Formula on Quality of Life Among Non-Small Cell Lung Cancer Patients Undergoing Chemotherapy: A Randomized Placebo-Controlled Trial

BACKGROUND

Cancer patients often experience decreased quality of life during chemotherapy. This study aimed to determine the preliminary efficacy and safety of Reishi & Privet Formula (RPF) for maintaining quality of life among patients with non-small cell lung cancer (NSCLC) undergoing chemotherapy.

METHODS

We conducted a phase II randomized, double-blind, placebo-controlled clinical trial in China. Adults with NSCLC scheduled to receive chemotherapy were randomly assigned (3:1 ratio) to receive oral RPF (3.36 g/day) or placebo daily for 6 weeks. The main outcome was the Functional Assessment of Cancer Therapy-Lung (FACT-L). We evaluated RPF's safety profile using the Common Terminology Criteria for Adverse Events and assessed changes in outcome measures from baseline to weeks 3 and 6 using a linear mixed effects model.

RESULTS

We enrolled 82 participants across 8 cancer centers in China. The median age was 59 years, 56 (68%) had advanced cancer. Compared with the placebo group, the RPF group had nonstatistically significant higher quality of life as measured by the FACT-L total score (P = .086) over 2 cycles of chemotherapy. The RPF group was associated with a nonsignificant better general health (P = .050) and emotional well-being (P = .090) than the placebo group. Adverse events rates did not differ between groups.

CONCLUSIONS

This study demonstrated preliminary safety and suggests a promising trend in RPF's effect on maintaining quality of life and emotional well-being among NSCLC patients undergoing chemotherapy. Future adequately powered randomized-controlled trials are needed to verify the efficacy and safety of RPF in cancer patients undergoing chemotherapy.

What if Acupuncture Were Covered by Insurance for Pain Management? A Cross-Sectional Study of Cancer Patients at One Academic Center and 11 Community Hospitals

OBJECTIVE

In response to the national opioid crisis, governmental and medical organizations have called for broader insurance coverage of acupuncture to improve access to nonpharmacologic pain therapies, especially in cancer populations, where undertreatment of pain is prevalent. We evaluated whether cancer patients would be willing to use insurance-covered acupuncture for pain.

DESIGN AND SETTING

We conducted a cross-sectional survey of cancer patients with pain at one academic center and 11 community hospitals.

METHODS

We used logistic regression models to examine factors associated with willingness to use insurance-covered acupuncture for pain.

RESULTS

Among 634 cancer patients, 304 (47.9%) reported willingness to use insurance-covered acupuncture for pain. In univariate analyses, patients were more likely to report willingness if they had severe pain (odds ratio [OR] = 1.59, 95% confidence interval [CI] = 1.03-2.45) but were less likely if they were nonwhite (OR = 0.59, 95% CI = 0.39-0.90) or had only received high school education or less (OR = 0.46, 95% CI = 0.32-0.65). After adjusting for attitudes and beliefs in multivariable analyses, willingness was no longer significantly associated with education (adjusted OR [aOR] = 0.78, 95% CI = 0.50-1.21) and was more negatively associated with nonwhite race (aOR = 0.49, 95% CI = 0.29-0.84).

CONCLUSIONS

Approximately one in two cancer patients was willing to use insurance-covered acupuncture for pain. Willingness was influenced by patients' attitudes and beliefs, which are potentially modifiable through counseling and education. Further research on racial disparities is needed to close the gap in utilization as acupuncture is integrated into insurance plans in response to the opioid crisis.

Association Between Music Therapy Techniques and Patient-Reported Moderate to Severe Fatigue in Hospitalized Adults With Cancer

PURPOSE

Cancer-related fatigue is a prevalent, debilitating symptom that contributes to increased health care utilization among hospitalized patients. Music therapy is a nonpharmacological intervention that uses active (eg, singing, selecting songs) and passive (eg, listening) techniques. Preliminary evidence from small trials suggests a potential benefit for cancer-related fatigue in the inpatient setting; however, it remains unclear which techniques are most effective.

METHODS

A cross-sectional mixed-methods study was performed to compare cancer-related fatigue before and after active or passive music therapy. Cancer-related fatigue was captured via the Edmonton Symptom Assessment Scale fatigue item. Patients were asked to provide postsession free-text comments.

RESULTS

A total of 436 patients (mean [standard deviation] age, 62.2 [13.4] years; n = 284 [65.1%] women; n = 294 [67.4%] white; active music therapy n = 360 [82.6%]; passive music therapy n = 76 [17.4%]) with a range of primary malignancies participated. Active music therapy was associated with a 0.88-point greater reduction in cancer-related fatigue (95% CI, 0.26 to 1.51; P = .006; Cohen's D, 0.52) at postsession as compared with passive music therapy when restricting the analysis to patients who rated their baseline cancer-related fatigue as moderate to severe (ie, ≥ 4; n = 236 [54.1%]). Free-text responses confirmed higher frequencies of words describing positive affect/emotion among active music therapy participants.

CONCLUSIONS

In a large sample of inpatient adults with diverse cancer disease types, active music therapy was associated with greater reduction in cancer-related fatigue and increased reporting of positive affect/emotions compared with passive music therapy. Additional research is warranted to determine the specific efficacy and underlying mechanisms of music therapy on cancer-related fatigue.

Effects of acupuncture versus cognitive behavioral therapy on cognitive function in cancer survivors with insomnia: A secondary analysis of a randomized clinical trial

BACKGROUND

Cancer-related cognitive impairment is a prevalent, disruptive condition potentially exacerbated by sleep disturbances. The current study was performed to evaluate the effects of acupuncture versus cognitive behavioral therapy for insomnia (CBT-I) on objective and subjective cognitive function in cancer survivors with insomnia.

METHODS

Using data from a randomized clinical trial (160 survivors) that compared acupuncture versus CBT-I for insomnia occurring in cancer survivors, the authors analyzed cognitive outcomes and their relationship to insomnia symptoms. Analysis was limited to 99 patients who reported baseline cognitive difficulties. Interventions were delivered over 8 weeks. Objective attention, learning, and memory were evaluated using the Buschke Selective Reminding Test. Subjective cognitive function was assessed using the Brown Attention-Deficit Disorder Scales. Insomnia symptoms were assessed using the Insomnia Severity Index. All outcomes were collected at baseline, week 8, and week 20.

RESULTS

From baseline to week 8, acupuncture produced statistically significant within-group improvements in objective attention (Cohen D, 0.29), learning (Cohen D, 0.31), and memory (Cohen D, 0.33) that persisted to week 20 (all P < .05), whereas CBT-I produced a statistically significant within-group improvement in objective attention from baseline to week 20 (Cohen D, 0.50; P < .05); between-group differences were not statistically significant. Both interventions produced statistically significant within-group improvements in subjective cognitive function at weeks 8 and 20 compared with baseline (all P < .001); between-group differences were not statistically significant. In the acupuncture group, patients with clinically meaningful responses with regard to insomnia symptoms demonstrated a significantly greater improvement in subjective cognitive function compared with those without clinically meaningful insomnia responses (P = .006).

CONCLUSIONS

Among cancer survivors with insomnia, both acupuncture and CBT-I produced significant improvements in objective and subjective cognitive function. However, the effect sizes varied and only survivors in the acupuncture group demonstrated a significant relationship between cognitive and sleep outcomes. These preliminary findings warrant further investigation to guide the personalized management of patients with cancer-related cognitive impairment.

Acupuncture Versus Cognitive Behavioral Therapy for Insomnia in Cancer Survivors: A Randomized Clinical Trial

BACKGROUND

Insomnia is a common and debilitating disorder experienced by cancer survivors. Although cancer survivors express a preference for using nonpharmacological treatment to manage insomnia, the comparative effectiveness between acupuncture and Cognitive Behavioral Therapy for Insomnia (CBT-I) for this disorder is unknown.

METHODS

This randomized trial compared 8 weeks of acupuncture (n = 80) and CBT-I (n = 80) in cancer survivors. Acupuncture involved stimulating specific points on the body with needles. CBT-I included sleep restriction, stimulus control, cognitive restructuring, relaxation training, and education. We measured insomnia severity (primary outcome), pain, fatigue, mood, and quality of life posttreatment (8 weeks) with follow-up until 20 weeks. We used linear mixed-effects models for analyses. All statistical tests were two-sided.

RESULTS

The mean age was 61.5 years and 56.9% were women. CBT-I was more effective than acupuncture posttreatment (P < .001); however, both acupuncture and CBT-I produced clinically meaningful reductions in insomnia severity (acupuncture: -8.31 points, 95% confidence interval = -9.36 to -7.26; CBT-I: -10.91 points, 95% confidence interval = -11.97 to -9.85) and maintained improvements up to 20 weeks. Acupuncture was more effective for pain at the end of treatment; both groups had similar improvements in fatigue, mood, and quality of life and reduced prescription hypnotic medication use. CBT-I was more effective for those who were male (P < .001), white (P = .003), highly educated (P < .001), and had no pain at baseline (P < .001).

CONCLUSIONS

Although both treatments produced meaningful and durable improvements, CBT-I was more effective and should be the first line of therapy. The relative differences in the comparative effectiveness between the two interventions for specific groups should be confirmed in future adequately powered trials to guide more tailored interventions for insomnia.

Drug metabolising enzyme polymorphisms and chemotherapy-related ovarian failure in young breast cancer survivors

Cyclophosphamide is associated with chemotherapy-related ovarian failure (CROF) in breast cancer survivors, however little is known about predicting individual risks. We sought to identify genetic alleles as biomarkers for risk of CROF after cyclophosphamide treatment. One hundred fifteen premenopausal women with newly diagnosed breast cancer were genotyped for single nucleotide polymorphisms (SNPs) in genes involved in cyclophosphamide activation (CYP3A4 and CYP2C19) and detoxification (GSTP1 and GSTA1). Patients prospectively completed menstrual diaries. With median follow up of 808 days, 28% experienced CROF. Survivors homozygous for the GSTA1 minor allele had lower hazards for developing CROF (HR 0.22 [95% CI 0.05-0.94], p=.04), while survivors homozygous for the CYP2C19 minor allele had higher hazards for developing CROF (HR 4.5 [95% CI 1.5-13.4], p=.007) compared to patients with at least one major allele. In separate multivariable models adjusting for age and tamoxifen use, the associations were no longer statistically significant (GSTA1 HR 0.24 [95% CI 0.06-1.0], p=.05; CYP2C19 HR 2.5 [0.8-7.6], p=.11). CYP3A4 and GSTP1 SNPs were not significantly related to CROF. In younger breast cancer survivors undergoing cyclophosphamide-based chemotherapy, genetic variation in CYP2C19 and GSTA1 merits further study to determine its relationship with CROF.IMPACT STATEMENTWhat is already known on this subject? Young breast cancer survivors face important potential implications of chemotherapy-related ovarian failure (CROF). Little is known about individual risk for CROF. Cyclophosphamide, a particularly gonadotoxic drug commonly used in breast cancer treatment, is metabolised by various cytochrome p450 enzymes. Studies have shown genetic variation in p450 enzymes is associated with differential clinical outcomes after cyclophosphamide treatment: breast cancer patients homozygous for GSTA1 minor allele had improved overall survival; lupus patients homozygous for CYP2C19 minor allele had increased risk for CROF; and CYP3A4*1B I was associated with decreased risk for CROF.What do the results of this study add? We show a surprising opposite trend for the risk of CROF in breast cancer patients with GSTA1 and CYP2C19 variants, while we did not show a significant risk for genetic variation in CYP3A4 (which had previously been shown to have a protective effect) or GSTP1.What are the implications of these findings for clinical practice and/or further research? This study shows the complexity of genetic variation in predicting outcomes to treatment. We advocate for future replicative studies to potentially validate GSTA1 and CYP2C19 and definitively negate CYP3A4 and GSTP1 as biomarkers for risk of CROF after cyclophosphamide treatment. Understanding genetic variation in chemotherapy metabolism has the potential to individualise treatment regimens to maximise efficacy and minimise toxicity.

Yoga for Chemotherapy-Induced Peripheral Neuropathy and Fall Risk: A Randomized Controlled Trial

Background

Chemotherapy-induced peripheral neuropathy (CIPN) is a common, debilitating side effect that worsens quality of life and increases the risk of falls in cancer survivors. Evidence of yoga’s safety and efficacy in treating CIPN is lacking.

Methods

In a randomized controlled study, we assigned breast and gynecological cancer survivors with persistent moderate-to-severe CIPN pain, numbness, or tingling with a score of 4 or greater (0-10 numeric rating scale [NRS]) for at least 3 months after chemotherapy to 8 weeks of usual care or yoga focused on breathwork and musculoskeletal conditioning. Primary endpoint was treatment arm differences for NRS, and secondary endpoints were Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity subscale (FACT/GOG-Ntx), and Functional Reach Test after week 8. We tested treatment arm differences for each outcome measure using linear mixed models with treatment-by-time interactions. All statistical tests were two-sided.

Results

We randomly assigned 41 participants into yoga (n = 21) or usual care (n = 20). At week 8, mean NRS pain decreased by 1.95 points (95% confidence interval [CI] = -3.20 to -0.70) in yoga vs 0.65 (95% CI = -1.81 to 0.51) in usual care (P = .14). FACT/GOG-Ntx improved by 4.25 (95% CI = 2.29 to 6.20) in yoga vs 1.36 (95% CI = -0.47 to 3.19) in usual care (P = .035). Functional reach, an objective functional measure predicting the risk of falls, improved by 7.14 cm (95% CI = 3.68 to 10.59) in yoga and decreased by 1.65 cm (95% CI = -5.00 to 1.72) in usual care (P = .001). Four grade 1 adverse events were observed in the yoga arm.

Conclusion

Among breast and gynecological cancer survivors with moderate-to-severe CIPN, yoga was safe and showed promising efficacy in improving CIPN symptoms.

Personalized electro-acupuncture versus auricular-acupuncture comparative effectiveness (PEACE): A protocol of a randomized controlled trial for chronic musculoskeletal pain in cancer survivors

INTRODUCTION

Chronic pain is a leading cause of disability and remains under-treated in nearly half of patients with cancer. The opioid crisis has highlighted an urgent public health need for effective nonpharmacological pain management. Electroacupuncture (EA) and Battlefield Acupuncture (BFA) represent nonpharmacological modalities used in clinical practice to manage pain; however, their effectiveness has not been rigorously evaluated in oncology settings.

METHODS

We describe the design of a 3-arm, parallel, single-center, multisite randomized controlled trial that investigates EA and BFA versus usual-care wait-list control (WLC) for chronic musculoskeletal pain among 360 patients with diverse cancer types across various stages. The primary aim is to compare effects of EA and BFA versus WLC on pain, physical function, and co-morbid symptoms. The secondary aim is to examine the interaction between patient outcome expectancy and acupuncture modality (EA vs BFA) on pain reduction. The tertiary aim is to evaluate the association between genetic polymorphisms and responses to acupuncture. Patients will be randomized in a 2:2:1 ratio to EA:BFA:WLC. Acupuncture groups will receive weekly treatments over 10 weeks. WLC will receive usual care over the same evaluation period as the acupuncture groups. The primary endpoint will be the change in average pain intensity score from baseline to week 12. We will collect validated patient-reported outcomes and blood/saliva samples at multiple timepoints over 24 weeks.

DISCUSSION

Our findings will advance nonpharmacological pain management in oncology and inform personalized treatment approaches that integrate individuals' expectations and genetic biomarkers to deliver "precision" acupuncture to cancer patients with chronic pain.

Implementation of Symptom Care Clinic (SCC) for acute symptoms management at outpatient oncology ambulatory centers

2030

Background: With improved overall cancer survival, increasing number of cancer patients are undergoing active treatment. This, in return, add burden in acute symptom management related to disease and treatment. This has resulted in increasing unplanned emergency room (ER) visits and negatively impacted patients experience and health cost. We establish Symptom Care Clinic (SCC) embedded in suburban ambulatory oncology centers to reduce unplanned ER lists and to improve patient experience. Methods: Together with all stakeholders, we developed six SCCs at regional ambulatory centers in NY and NJ. Clearly defined work flow and algorithm were developed to ensure appropriate patient referral. On-site radiology and laboratory services are available. The SCCs are staffed with combination of Advanced Practice Provided (APP) and physicians or APP alone supported by on site medical oncologist or remote central Urgent Care Center Attendings. We evaluated clinic volumes, reduction ins unplanned ER visits and patient experience. Results: From October 2017 to December 2019, total of 17,542 SCC visits were documented. Total of 17,479 lab and 5,355 radiology tests as well as 3,915 infusions were performed. The top five most common laboratory tests are CBC, blood cultures, CMP, respiratory panel and urine culture. The most common symptoms are fever, nausea/vomiting/dehydration, rash and pain. Among all SCC visits during this period, 83% were discharged home and 17% were transferred to ER or hospitals. During 2019, total 10,736 SCC visits were recored, APP evaluated 73.7% of visits and physicians 16.3% with comaprable recidivism rate, 2.52% and 2.75%, respectively. Conservatively, we estimated that approximately 40% of visits would have been Er visits based on numbers of CBC and other testes performed. Qualitative feedbacks from patients indicated positive experience in convenient access, cohesive care coordination and time saving from traveling to and waiting in ER. Conclusions: We successfully implemented an effective acute symptom management system in busy ambulatory oncology centers that is patient centric. Out data showed that SCC reduced unplanned ER visits and that APP/physician model has low recidivism rate.

Association between gut microbiome and T lymphocytes among different primary tumor sites of patients with metastatic colorectal cancer

e16013

Background: Different primary tumor sites could impact colorectal cancer (CRC)’s survival outcomes and treatment effects. Previous studies had found that gut micro-biome distributions were different between left and right colon cancer(LCC, RCC). Out study aimed to further investigate the association between micro-biome and T lymphocytes among different tumor sites of patients with metastatic CRC. Methods: Between April 2018 and Mars 2019, we enrolled 40 metastatic CRC patients in Xiyuan Hospital of China Academy of Chinese Medical Sciences, Beijing, China. We collected patients’ stool samples for micro-biome analysis by 16s rRNA sequencing approaches, as well as patients’ blood samples to analyses T lymphocyte subsets by flow cytometry methods. The study had been proved by ethics committee of Xiyuan Hospital (2016XLA122-1). All patients consented before enrollment. Results: Among 40 patients, 28% were female, with average age of 63±15 years old. There were 10 RCC, 9 LCC and 21 rectal cancer(RC) patients. Alpha diversity analysis showed that sobs index of the micro-biome of patients with RC and RC was significantly higher than whom were RCC(254.89±99, 247±89 versus.[vs.]101.17±51, p= 0.001). PCoA analysis on OTU level detected that first principal component[PC1] (26.24%) could be separated significantly between RCC and LCC( p= 0.048), as well as between RC and RCC (PC1,14.17%, p= 0.024). Community analysis showed that the proportion of Bacteroidetes was significantly higher in patients with RCC than whom with LCC and RC( p= 0.009). Conversely, the proportion of Firmicutes, Proteobacteria and Verrucomicrobia were higher in LCC patients than others( p= 0.37, 0.047 and 0.032 respectively). Canonical Correlation Analysis (CCA) analysis proved that the CD4+ and CD8+ T cells counts were environmental factors, which were significantly associated with certain micro-biome and samples from different tumor sites( p= 0.037 and 0.01 respectively). Trends showed that CD4+ T cells were positively related with samples of RC and bacteria parabacteroides and bifidobacterium, while CD8+ T cells were positively related with samples of RCC and bacteria Lachnospira, Sutterella and Bacteroides. Conclusions: In our study, we found that patients with LCC and RC had more beneficial gut micro-biome than whom with RCC. In addition, such difference might be associated with body T cell immunity.

Effects of electroacupuncture and auricular acupuncture for chronic pain in cancer survivors: The PEACE randomized controlled trial

12004

Background: The national opioid crisis has created new challenges in oncology pain management and highlighted an urgent need for non-pharmacological treatments. We evaluated the comparative effectiveness of electro-acupuncture (EA) and auricular acupuncture (AA) versus usual care (UC) for chronic musculoskeletal pain in cancer survivors. Methods: We conducted a randomized controlled trial of cancer survivors experiencing moderate-severe musculoskeletal pain for at least 3 months. EA used a semi-individualized protocol involving electrical stimulation of needles placed in the body. AA used the standardized Battlefield Acupuncture protocol involving up to 10 needles placed in the ears. EA and AA groups received 10 weekly treatments, whereas participants in the UC group received standard care prescribed by their providers. The primary endpoint was average pain severity change measured by the Brief Pain Inventory at week 12 compared to baseline. Functional interference and quality of life were secondary outcomes. We analyzed longitudinal mixed-effects models based on intent-to-treat principles. Results: Among 360 participants, mean age (SD) was 62.1 (12.7) years, 251 (69.7%) were women, and 88 (24.4%) were non-white. Compared from baseline to week 12, EA significantly reduced pain severity by 1.9 points (95% Confidence Interval 1.5-2.3, p < 0.001), and AA significantly reduced pain severity by 1.6 points (1.1-2.0, p < 0.001). AA was non-inferior to EA at reducing pain severity (p = 0.04). Both EA and AA also significantly improved functional interference (both p < 0.001), physical health (both p < 0.001), and mental health (p = 0.003, p < 0.001) compared to UC. Adverse events (AEs) were mild in both groups; however, 16 (11.2%) in AA stopped treatment due to AEs (mostly ear discomfort) as compared to 1 in EA (0.7%), p = 0.001. Conclusions: Among cancer survivors with chronic musculoskeletal pain, both EA and AA effectively reduced pain and improved quality of life. AA was non-inferior to EA at reducing pain but associated with higher discontinuation rates. These results will guide implementation of acupuncture in oncology care to address the unmet pain management needs of cancer survivors in the era of the opioid epidemic.

Characterization of chemotherapy-induced peripheral neuropathy (CIPN) using patient-reported outcomes (PRO) and quantitative sensory testing (QST)

e24078

Background: CIPN is a common, potentially debilitating, and dose-limiting side effect experienced by cancer survivors. CIPN encompasses symptoms such as pain, numbness, and tingling, which can be measured subjectively by PRO, or semi-objectively by QST; however, little is known about how QST measures differ among patients with and without CIPN, or if QST outcomes correlate with symptom profiles measured by PRO. Methods: CIPN is a common, potentially debilitating, and dose-limiting side effect experienced by cancer survivors. CIPN encompasses symptoms such as pain, numbness, and tingling, which can be measured subjectively by PRO, or semi-objectively by QST; however, little is known about how QST measures differ among patients with and without CIPN, or if QST outcomes correlate with symptom profiles measured by PRO. Results: 116 patients with CIPN and 10 control patients without CIPN were analyzed. NRS and FACT/GOG-Ntx scores were significantly worse in the CIPN group compared to controls (all p< 0.001). The mean (Standard Deviation) TT for CIPN and control patients was 3.61 (0.43) and 3.38 (0.32), respectively (p = 0.059), in hands; and 3.86 (0.70) and 3.38 (0.56), respectively (p = 0.043), in feet. The mean VT was 6.06 (3.45) and 3.87 (1.01), respectively (p=0.032), in hands; and 19.14 (11.09) and 8.43 (3.22), respectively (p<0.001), in feet. There was no significant difference in THT between groups. The correlation coefficients between PRO with QST measures in all patients are listed in the table below. Conclusions: Our study suggested that patients with CIPN have significantly worse symptoms and tactile and vibratory threshold measured by QST when compared with controls. Mild to moderate correlations were observed between PROs and QST, suggesting that CIPN symptoms severity correspond to sensory sensitivity. As CIPN presents a diverse range of symptoms, improved quantification of subjective and objective measures for CIPN can help the incorporation of these tools into future clinical trials.

Effects of auricular acupuncture on appetite in patients with advanced cancer: a pilot randomized controlled trial

BACKGROUND

Over half of patients with advanced cancer report appetite loss or anorexia. Previous studies have shown the benefit of acupuncture for cancer-related nausea and vomiting, but limited evidence exists for its role in appetite improvement. Our study aimed to evaluate the feasibility and safety of auricular acupuncture to improve appetite for cancer patients with advanced disease.

METHODS

We performed a two-arm parallel, pilot randomized controlled trial (RCT) of auricular acupuncture versus usual care control in patients with stage III or IV cancer who experienced appetite loss. The primary outcome was changed in the Simplified Nutritional Appetite Questionnaire (SNAQ; score range, 4-20) between two groups from baseline to weeks 2 and 4, with secondary outcomes including change in weight, as well as an additional evaluation at week 8 for durability of treatment effects. We used independent two-sample t-test for the change in mean score for each outcome during or after treatment. We assessed the interaction between time and treatment from baseline to weeks 2, 4, and 8 using mixed-effects models by ANOVA test.

RESULTS

We randomized 55 patients to auricular acupuncture (N=27) or control group (N=28). By week 4, the auricular acupuncture group had a significantly higher escalation in the SNAQ score than the control group compared with baseline [mean difference 3.69; 95% confidential interval (95% CI): 2.5, 4.8; P<0.001] and experienced a 51.4% improvement in appetite. From baseline to weeks 2 and 4, patients lost a little weight in the control group but gained weight in the auricular acupuncture group. Between baseline and week 4, change in the SNAQ score was significantly associated with change in weight (P=0.001). No adverse events (AEs) were reported during the study.

CONCLUSIONS

Compared to usual care, auricular acupuncture is feasible and safe to improve appetite and help patients with advanced cancer gain weight.

Effect of Acupuncture vs Sham Procedure on Chemotherapy-Induced Peripheral Neuropathy Symptoms: A Randomized Clinical Trial

This randomized clinical trial investigates the effect of acupuncture vs a sham procedure or usual care for chemotherapy-induced peripheral neuropathy symptoms.

When Patients Take Charge of Opioids: Self-Management Concerns and Practices Among Cancer Outpatients in the Context of Opioid Crisis

CONTEXT

With concerns about opioid prescribing practices prominent in the professional and lay literature, there is less focus on patients' self-management of opioids for cancer pain and potential safety risks.

OBJECTIVES

To investigate reports of opioid self-management practices and concerns among patients undergoing active cancer treatments-a group excluded from the scope of most policy initiatives on prescription opioids.

METHODS

This sequential multimethod study used freelisting (n = 65) and open-ended semistructured interviews with a racially diverse subgroup (n = 32). Adult ambulatory patients with solid malignancies or multiple myeloma and pain (≥4 on a scale of 0-10) were recruited from an urban National Cancer Institute-designated cancer center in Philadelphia. Freelists were analyzed using consensus analysis and semistructured interview data were analyzed using thematic analysis.

RESULTS

In freelisting, "pain relief" emerged as the primary term in relation to taking pain medications preceding "addiction" concerns. In interviews, patients described several heuristics and some potentially unsafe practices to minimize opioid use to a self-defined "normal." These included reducing opioid dose by cutting pills; self-tapering off opioids; using extended-release/long-acting opioids on an as-needed basis; mixing over-the-counter, nonopioid analgesics; and using illicit drugs to avoid "harder medicines" (opioids). Many patients preferred nonopioid treatments for pain but invariably faced access barriers. Some described assuming stewardship of their prescribed opioids and felt that oncology clinicians are quick to prescribe opioids without providing workable alternatives.

CONCLUSIONS

Risks related to self-management of opioids among cancer outpatients, including potential overdose risks, need urgent attention. Interventions are needed for improving clinician-patient communication, patient education, safety, and access to effective nonopioid alternatives.

The unique burden of rare cancer caregiving: caregivers of patients with Erdheim-Chester disease

Research examining the experience of informal caregivers (ICs) for patients with rare cancers is limited. This was a mixed-methods pilot study of 14 ICs for patients with Erdheim-Chester disease (ECD), an ultra-rare neoplasm. Participants were predominantly female and over half provided at least 60% of their loved one's care. Participants completed measures of the impact of caregiving, caregiver burden, unmet needs, quality of life, anxiety, and depression. Participants reported substantial impact of caregiving, including limiting (50%) or discontinuing (21%) paid employment, and exhausting financial savings (43%). ICs reported a moderate level of burden with five (38%) reporting risk for burnout. While participants reported anxiety (64%) and depression (14%), their overall quality of life was favorable. Semi-structured interviews highlighted factors related to the distress and isolation of navigating a rare cancer. ECD ICs report burden and distress shaped by the experience of providing care for a patient with a rare cancer.

Putative Antidepressant Effect of Chamomile (Matricaria chamomilla L.) Oral Extract in Subjects with Comorbid Generalized Anxiety Disorder and Depression

Objectives: This exploratory analysis examined the putative antidepressant effect of Matricaria chamomilla L. (chamomile) extract in subjects with generalized anxiety disorder (GAD) with or without comorbid depression. It was hypothesized that chamomile extract would demonstrate similar anxiolytic activity in both subgroups, but superior antidepressant activity in GAD subjects with comorbid depression. Design: As part of a randomized double-blind placebo-controlled trial of chamomile extract for relapse prevention of GAD, 179 subjects received initial therapy with open-label chamomile extract 1500 mg daily for 8 weeks. Linear mixed-effect models were used to identify clinically meaningful changes in anxiety and depression symptoms between diagnostic subgroups. Settings/Location: The study took place at the University of Pennsylvania in Philadelphia, PA. Subjects: Subjects were ≥18 years old with a primary DSM IV-TR diagnosis of GAD. They were subcategorized into two diagnostic groups: GAD without comorbid depression (n = 100) and GAD with comorbid depression (n = 79). Interventions: Open-label chamomile extract 1500 mg was given daily for 8 weeks. Outcome measures: Generalized anxiety disorder (GAD-7), Hamilton rating scale for anxiety, Beck anxiety inventory, Hamilton rating scale for depression (HRSD), the six-item core HRSD (items 1, 2, 3, 7, 8, and 13), and the Beck depression inventory (BDI). Results: The authors observed similar anxiolytic effects over time in both diagnostic subgroups. However, there was a greater reduction in HRSD core symptom scores (p < 0.023), and a trend level reduction in HRSD total scores (p = 0.14) and in BPI total scores (p = 0.060) in subjects with comorbid depression. Conclusions: M. chamomilla L. may produce clinically meaningful antidepressant effects in addition to its anxiolytic activity in subjects with GAD and comorbid depression. Future controlled trials in subjects with primary major depressive disorder are needed to validate this preliminary observation.

A Technology-Assisted, Brief Mind-Body Intervention to Improve the Waiting Room Experience for Chemotherapy Patients: Randomized Quality Improvement Study

Background

Patients waiting for chemotherapy can experience stress, anxiety, nausea, and pain. Acupressure and meditation have been shown to control such symptoms.

Objective

This study aimed to evaluate the feasibility and effectiveness of an integrative medicine app to educate patients about these self-care tools in chemotherapy waiting rooms.

Methods

We screened and enrolled cancer patients in chemotherapy waiting rooms at two Memorial Sloan Kettering Cancer Center locations. Patients were randomly assigned into an intervention arm in which subjects watched acupressure and meditation instructional videos or a control arm in which they watched a time- and attention-matched integrative oncology lecture video. Before and after watching the videos, we asked the patients to rate four key symptoms: stress, anxiety, nausea, and pain. We performed the analysis of covariance to detect differences between the two arms postintervention while controlling for baseline symptoms.

Results

A total of 223 patients were enrolled in the study: 113 patients were enrolled in the intervention arm and 110 patients were enrolled in the control arm. In both groups, patients showed significant reductions in stress and anxiety from baseline (all P<.05), with the treatment arm reporting greater stress and anxiety reduction than the control arm (1.64 vs 1.15 in stress reduction; P=.01 and 1.39 vs 0.78 in anxiety reduction; P=.002). The majority of patients reported that the videos helped them pass time and that they would watch the videos again.

Conclusions

An integrative medicine self-care app in the waiting room improved patients’ experiences and reduced anxiety and stress. Future research could focus on expanding this platform to other settings to improve patients’ overall treatment experiences.

Clinical and genetic risk factors for aromatase inhibitor-associated arthralgia in breast cancer survivors

BACKGROUND

Arthralgia is a common and debilitating toxicity of aromatase inhibitors (AI) that leads to premature drug discontinuation. We sought to evaluate the clinical and genetic risk factors associated with AI-associated arthralgia (AIAA).

METHODS

We performed a cross-sectional study among postmenopausal women with stage 0-III breast cancer who were prescribed a third-generation AI for adjuvant therapy. The primary outcome was patient-reported AIAA occurrence. We extracted and assayed germline DNA for single nucleotide polymorphisms (SNPs) of genes implicated in estrogen and inflammation pathways. Multivariable logistic regression models examined the association between demographic, clinical, and genetic factors and AIAA. Analyses were restricted to White participants.

RESULTS

Among 1049 White participants, 543 (52%) reported AIAA. In multivariable analyses, women who had a college education [Adjusted Odds Ratio (AOR) 1.49, 95% Confidence Interval (CI) 1.00-2.20], had a more recent transition into menopause (<10 years) (5-10 years AOR 1.55, 95% CI 1.09-2.22; <5 years AOR 1.78, 95% CI 1.18-2.67), were within one year of starting AIs (AOR 1.61, 95% CI 1.08-2.40), and those who received chemotherapy (AOR 1.38, 95% CI 1.02-1.88) were significantly more likely to report AIAA. Additionally, SNP rs11648233 (HSD17B2) was significantly associated with higher odds of AIAA (AOR 2.21, 95% CI 1.55-3.16).

CONCLUSIONS

Time since menopause and start of AIs, prior chemotherapy, and SNP rs11648233 within the HSD17B2 gene in the estrogen pathway were significantly associated with patient-reported AIAA. These findings suggest that clinical and genetic factors involved in estrogen withdrawal increase the risk of AIAA in postmenopausal breast cancer survivors.

Both Race and Insurance Type Independently Predict the Selection of Oral Opioids Prescribed to Cancer Outpatients

BACKGROUND

Previous research suggests that racial disparities in patients' reported analgesic adverse effects are partially mediated by the type of opioid prescribed to African Americans despite the presence of certain comorbidities, such as renal disease.

AIMS

We aimed to identify independent predictors of the type of opioid prescribed to cancer outpatients and determine if race and chronic kidney disease independently predict prescription type, adjusting for relevant sociodemographic and clinical confounders.

DESIGN

We conducted a secondary analysis of a 3-month observational study.

SETTING

Outpatient oncology clinics of an academic medical center.

PARTICIPANTS/SUBJECTS

Patients were older than 18 years of age, self-identified as African American or White, and had an analgesic prescription for cancer pain.

METHODS

Cancer patients (N = 241) were recruited from outpatient oncology clinics within a large mid-Atlantic healthcare system.

RESULTS

Consistent with published literature, most patients (75.5%) were prescribed either morphine or oxycodone preparations as oral opioid therapy for cancer pain. When compared with Whites, African Americans were significantly more likely to be prescribed morphine (33% vs 14%) and less likely to be prescribed oxycodone (38% vs 64%) (p < .001). The estimated odds for African Americans to receive morphine were 2.573 times that for Whites (95% confidence interval 1.077-6.134) after controlling for insurance type, income, and pain levels. In addition, the presence of private health insurance was negatively associated with the prescription of morphine and positively associated with prescription of oxycodone in separate multivariable models. The presence of chronic kidney disease did not predict type of analgesic prescribed.

CONCLUSIONS

Both race and insurance type independently predict type of opioid selection for cancer outpatients. Larger clinical studies are needed to fully understand the sources and clinical consequences of racial differences in opioid selection for cancer pain.

Chemotherapy-induced peripheral neuropathy (CIPN) in breast cancer survivors: a comparison of patient-reported outcomes and quantitative sensory testing

PURPOSE

CIPN is a common, debilitating, and dose-limiting side effect of chemotherapy. Here, we describe characteristics of patients with CIPN using both patient-reported outcomes (PRO) and quantitative sensory testing (QST).

METHODS

Breast cancer survivors with persistent moderate to severe CIPN defined by a rating of 4 or greater on a 0-10 Numeric Rating Scale (NRS) from two ongoing clinical trials were included. PROs included the Neuropathic Pain Scale (NPS) and Functional Assessment of Cancer Therapy-Gynecologic Oncology Group/Neurotoxicity (FACT/GOG-Ntx). QST included tactile and vibration detection threshold measurements. Data were analyzed using descriptive statistics and Spearman correlation coefficients.

RESULTS

49 female patients with a mean age of 61 years were assessed; 63% were Caucasian. Mean NRS scores were 4.2, 5.7, and 4.3 on 0-10 scale for pain, numbness, and tingling, respectively. Mean NPS score was 41.0 on a 0-100 scale, and the mean FACT/GOG-Ntx score was 25.8 on a 0-44 scale. QST showed mild to moderate impairments in tactile and vibration perception. The FACT/GOG-Ntx subscale for numbness was negatively correlated with tactile and vibration thresholds in both hands and feet (both p < 0.05). NPS was positively correlated with tactile thresholds in the hands and feet (p < 0.05).

CONCLUSION

Patients with moderate to severe CIPN report moderate pain, numbness, and tingling, and exhibit reduced tactile and vibration perception on QST. Weak to moderate correlations were observed between PRO and QST. These data suggest that QST outcomes are associated with CIPN symptoms and may be useful in helping monitor and manage CIPN treatment.

Effects of infrared laser moxibustion on cancer-related fatigue in breast cancer survivors: Study protocol for a randomized controlled trial

BACKGROUND

Cancer-related fatigue (CRF) is the most common and distressing symptom associated with cancer treatment that breast cancer survivors (BCS) experience. We previously found that laser moxibustion may be efficacious for CRF. The primary aim of this study is to determine the specific efficacy of 10.6 μm infrared laser moxibustion on CRF. The secondary aim is to evaluate the effect of infrared laser moxibustion on co-existing symptoms that BCS experience.

METHODS

We will conduct a randomized, sham-controlled, three-arm trial of infrared laser moxibustion (ILM) against sham ILM (SILM) and waitlist control (WLC) among BCS with moderate to severe fatigue. The two intervention groups will receive either real or sham infrared laser moxibustion on four acupoints (i.e., ST36 [bilateral], CV4, and CV6) for 20 minutes each session for 6 weeks (twice per week). The primary endpoint is the change in fatigue score from Baseline to Week 6 as measured by the Chinese version of the Brief Fatigue Inventory (BFI-C). Our secondary aim is to compare the severity of co-morbidities (e.g., depression, insomnia, and pain) among the 3 groups.

DISCUSSION

The results of our trial will establish evidence for the efficacy of infrared laser moxibustion for CRF, a very common and challenging symptom.
