The potential role for acupuncture in treating symptoms in patients with lung cancer: an observational longitudinal study

Patient-reported outcomes and functional exercise capacity in a real-life setting in non-small cell lung cancer patients undergoing stereotactic body radiotherapy: the Lung PLUS study

Introduction

To better understand the impact of stereotactic body radiotherapy (SBRT) and its treatment-related toxicity on early-stage non-small cell lung cancer (ES-NSCLC) patients, we conducted the Lung PLUS study in a real-world setting.

Methods

This is a monocentric prospective longitudinal study up to 12 months post-treatment, evaluating clinician- and patient-reported toxicity (resp. CTCAE and PRO-CTCAE), health-related quality of life (HRQoL) (EORTC QLQ-C30 and LC-13), activities of daily living (HAQ-DI) and functional exercise capacity (6 Minute Walking Test (6MWT)). A mixed model approach was applied to analyze the data.

Results

At baseline, clinicians and patients (n=51) reported mostly fatigue (63% vs 79%), cough (49% vs 75%) and dyspnea (65% vs 73%) of any grade. Dyspnea (p=.041) increased over time. Meaningful clinical improvements were particularly seen in pain, fatigue, and cough. Clinician reported clinically meaningful improvements and deteriorations over time in fatigue, cough, and dyspnea. Almost at every timepoint, more people reported deterioration to the clinician than improvement in aforementioned toxicities. Overall HRQoL (p=.014), physical (p=.011) and emotional (p<.001) functioning improved over time. At baseline, patients had a moderate daily functioning score and walked an average distance of 360 meters. No statistically significant differences were found in daily functioning and exercise capacity over time.

Conclusion

Our study showed an increase in patient-reported toxicity and dyspnea, without impacting functional status, following SBRT. Overall HRQoL, physical and emotional functioning improved over time. Understanding the impact of treatment on patient-reported outcomes is crucial to identify the needs/problems of patients to enhance their HRQoL.

Acupuncture and Derived Therapies for Pain in Palliative Cancer Management: Systematic Review and Meta-Analysis Based on Single-Arm and Controlled Trials

Background: Acupuncture is a classical complementary therapy, but benefits in palliative cancer pain are still unclear due to lack of consistent evidence. Objectives: To comprehensively evaluate the effectiveness of acupuncture and derived therapies (such as electroacupuncture, laser acupuncture, and transcutaneous electrical nerve stimulation) for analgesia in palliative cancer care based on both single-arm and controlled trials. Design: Eight databases were searched from inception to August 31, 2020. Both single-arm trials and controlled trials were included. The primary outcome was the change in pain intensity, as evaluated by the numeric rating scale (NRS) and the visual analog scale. Subjects: Adults with cancer. Results: Forty-one controlled studies with 2685 participants and 18 single-arm studies with 1084 participants were included. For controlled trials, meta-analysis indicated that acupuncture and derived therapies in addition led to greater reductions in the NRS score than conventional analgesics alone (weighted mean difference [WMD]: 1.33 [0.85-1.82], p < 0.001). For single-arm trials, meta-analysis showed that both the immediate effect (WMD: 1.57 [1.43-1.71], p < 0.001) and long-term longitudinal effect (WMD: 1.81 [1.25-2.37], p < 0.001) of acupuncture on analgesia were positive, as evaluated by the NRS, respectively. The benefits of acupuncture and derived therapies were also seen in quality of life and the global improvement rate. LI4 (Hegu) was the most frequently used acupoint. Conclusions: This systematic review supported the application of acupuncture and derived therapies for managing pain during palliative cancer care from two dimensions. Further studies could explore the effect of acupuncture on other predominant symptoms in palliative cancer patients.

Effect of Acupuncture in Pain Management of Head and Neck Cancer Radiotherapy: Prospective Randomized Unicentric Study

This prospective randomized open-label trial aimed to evaluate the role of acupuncture in the treatment of pain related to curative and adjuvant (chemo)radiotherapy of head and neck cancer. Patients in two arms (30 patients in each arm) underwent standard oncology therapy and standard supportive care with or without acupuncture. The stratification factors were the type of treatment and chemotherapy indication. The toxicity assessed was represented by pain rated on a 10-point pain scale and analgesic use. Average pain (AP) and the worst pain during the day (WP) were significantly lower in the acupuncture arm during radiotherapy (AP median 0.16 vs. 1.36, p < 0.001; WP median 0.90 vs. 1.96, p < 0.001) and three months after radiotherapy (AP median 0.07 vs. 0.50, p < 0.001; WP median 0.30 vs. 0.83, p = 0.002). The analgesic consumption between arms was statistically significantly different. A median of the proportion of days when the patients used analgesics was 8% and 32.5% during radiotherapy (p = 0.047) and 0% and 20.8% during three months after radiotherapy (p = 0.006) for the acupuncture and control arm, respectively. Results point out lower analgesic consumption and milder pain in acupuncture arm. Acupuncture consequently offers another alternative to standard treatment leading to a reduction in the toxicity of oncological treatment.

Health-Related Quality of Life in Patients with Lung Cancer Applying Integrative Oncology Concepts in a Certified Cancer Centre

Background

Pretreatment health-related quality of life (HRQOL) is associated with survival outcome in lung cancer patients. There is a lack of systematic research on pretreatment HRQOL in lung cancer patients who receive integrative oncology (IO). We evaluated patient-reported outcomes in these patients at time of diagnosis at a certified oncology and lung cancer centre.

Methods

The present analysis is a prospective real-world data study. Clinical and demographic data were obtained from the accredited Network Oncology cancer registry. Pretreatment HRQOL was evaluated (international standardized questionnaires) for people with all-stage lung cancer at first diagnosis that received IO consisting of standard therapy and multimodal add-on complementary concepts. Univariate and adjusted multivariate regression analyses were performed with R. Results. Eighty seven patients with all-stage lung cancer were eligible for the questionnaire analysis (median age 68.0 years, IQR 59.0–74.4). Thirty percent of the total cohort reported financial difficulties. Self-reported pretreatment financial difficulty was associated with younger age (p=0.007), pretreatment pain (p=0.006), anxiety (p=0.04), and low mood (p=0.03). Pain (p=0.03) and young age (p=0.02) in the early- and late-stage lung cancer were associated with financial difficulties.

Conclusion

We suggest physicians screen lung cancer patients at working age (broadly aged ≤65 years) and/or who report increased pain at the time of diagnosis as they might be at particular risk for emotional, physical, and financial problems. Our results emphasize to address emotional and physical needs before and during early treatment in lung cancer patients as suggested in integrative and supportive cancer concepts.

Acupressure to Reduce Treatment-Related Symptoms for Children With Cancer and Recipients of Hematopoietic Stem Cell Transplant: Protocol for a Randomized Controlled Trial

BACKGROUND

We describe the study design and protocol of a pragmatic randomized controlled trial (RCT) Acupressure for Children in Treatment for a Childhood Cancer (ACT-CC).

OBJECTIVE

To describe the feasibility and effectiveness of an acupressure intervention to decrease treatment-related symptoms in children in treatment for cancer or recipients of a chemotherapy-based hematopoietic stem cell transplant (HSCT).

DESIGN

Two-armed RCTs with enrollment of 5 to 30 study days.

SETTING

Two pediatric teaching hospitals.

PATIENTS

Eighty-five children receiving cancer treatment or a chemotherapy-based HSCT each with 1 parent or caregiver.

INTERVENTION

Patients are randomized 1:1 to receive either usual care plus daily professional acupressure and caregiver delivered acupressure versus usual care alone for symptom management. Participants receive up to 20 professional treatments.

MAIN OUTCOME

A composite nausea/vomiting measure for the child.

SECONDARY OUTCOMES

Child's nausea, vomiting, pain, fatigue, depression, anxiety, and positive affect.

PARENT OUTCOMES

Depression, anxiety, posttraumatic stress symptoms, caregiver self-efficacy, and positive affect. Feasibility of delivering the semistandardized intervention will be described. Linear mixed models will be used to compare outcomes between arms in children and parents, allowing for variability in diagnosis, treatment, and age.

DISCUSSION

Trial results could help childhood cancer and HSCT treatment centers decide about the regular inclusion of trained acupressure providers to support symptom management.

Utility of the revised Edmonton Symptom Assessment System (ESAS-r) and the Patient-Reported Functional Status (PRFS) in lung cancer patients

BACKGROUND

Symptom palliation is an important objective of treatment in advanced/metastatic lung cancer (LC). Significant psychological, minor physical symptoms and several social/emotional issues often go unnoticed. This prospective study aimed to evaluate utility of patients' perspectives [self-reported symptom assessment by revised Edmonton Symptom Assessment System (ESAS-r) and self-reported functional status by Patient-Reported Functional Status (PRFS)] amongst LC patients undergoing chemotherapy.

METHODS

Consecutive newly diagnosed treatment-naïve LC patients attending a tertiary referral center in North India from January 2014 to March 2015 were included. All patients received standard histology-guided platinum-doublet chemotherapy. ESAS-r and PRFS questionnaires were administered under guidance, once at the time of initial assessment/diagnosis, repeated at start of chemotherapy, before C4, and after completion of chemotherapy (end of chemotherapy (EOCTx)). Functional Assessment of Cancer Therapy-Lung (FACT-L) questionnaire was also administered. Baseline and post-treatment scores were compared.

RESULTS

Majority of 133 patients enrolled were males (86.5%,n = 115), were current/ex-smokers (81.2%, n = 108), had advanced stage [IIIB = 30.1% (n = 40), IV = 52.6% (n = 70)], and were of non-small-cell type (NSCLC;84.2%,n = 112). On baseline ESAS-r, the highest mean symptom scores were observed for tiredness followed by anorexia. Mean ESAS-r scores before C4 as well as at EOCTX were significantly better than baseline ESAS-r scores in all its components except nausea. Similarly, PRFS before C4 and EOCTx was significantly improved compared to baseline. However, Karnofsky Performance Scale (KPS) and Eastern Cooperative Oncology Group Performance Status assessed at baseline did not show significant improvement at treatment completion. FACT-L score at EOCTx showed significant improvement from baseline in physical and functional well-being domains but not for social/family and emotional well-being domains.

CONCLUSION

This study validated utility of ESAS-r and PRFS in Indian LC patients. These instruments should be used in routine clinical practice besides physicians' assessment of PS (KPS/ECOG).

Fatigue in lung cancer patients: symptom burden and management of challenges

Lung cancer (LC) remains the most common cause of cancer death in several countries across the world. Fatigue is the most frequently reported symptom in LC patients throughout the entire course of disease, and all international guidelines recommend early screening for cancer-related fatigue (CRF) and symptoms that can affect patients' quality of life. In patients with LC, fatigue belongs to the symptom cluster of pain, depression, and insomnia, which are commonly observed simultaneously, but are typically treated as separate although they may have common biological mechanisms. The treatment of CRF remains one of the difficult areas in the oncology field: scarce evidence supports pharmacological therapies, while some interesting data arising indicates alternative remedies and physical exercise seem to be one of the most effective approaches for CRF at any stage of LC.

Patient-reported Outcomes of Acupuncture for Symptom Control in Cancer

Acupuncture is increasingly offered as a treatment option for managing cancer-related symptoms. In addition to randomized controlled trials, patient-reported outcomes may be needed to establish treatment effectiveness. This study retrospectively examined the symptoms and the satisfaction ratings of 90 patients receiving acupuncture at an integrative oncology clinic. At least two acupuncture sessions were completed by 72% of the sample. The prevalence rates of fatigue, pain, anxiety, physical distress, emotional distress, and poor quality of life before acupuncture were > 62%. Paired t tests revealed a significant reduction in symptoms from baseline until after the first acupuncture session and after the last session (p < 0.05). Fewer (21%) patients reported nausea, which was significantly reduced after the first session, but not the last session. Reductions represented clinically meaningful differences in 33-41% of patients after the first session and in 41-53% of patients after the last session for all symptoms, except nausea. A small subset of patients (0-8%) reported worsening symptoms after acupuncture. The majority were satisfied with the service. The results of this study suggest that acupuncture may be useful as an adjunct treatment for cancer symptom management. While high-quality trials are still needed to establish the treatment's efficacy, patients may benefit from these primarily safe, low-cost services.

Psychiatric benefits of integrative therapies in patients with cancer

Integrative oncology uses non-pharmacological adjuncts to mainstream care to manage physical, emotional, and psychological symptoms experienced by cancer survivors. Depression, anxiety, fatigue and pain are among the common, often burdensome symptoms that can occur in clusters, deplete patient morale, interfere with treatment plans, and hamper recovery. Patients already seek various modalities on their own to address a broad range of problems. Legitimate complementary therapies offered at major cancer institutions improve quality of life, speed recovery, and optimize patient support. They also augment the benefits of psychiatric interventions, due to their ability to increase self-awareness and improve physical and psychological conditioning. Further, these integrated therapies provide lifelong tools and develop skills that patients use well after treatment to develop self-care regimens. The active referral of patients to integrative therapies achieves three important objectives: complementary care is received from therapists experienced in working with cancer patients, visits become part of the medical record, allowing treatment teams to guide individuals in maximizing benefit, and patients are diverted from useless or harmful 'alternatives.' We review the reciprocal physical and psychiatric benefits of exercise, mind-body practices, massage, acupuncture, and music therapy for cancer survivors, and suggest how their use can augment mainstream psychiatric interventions.
