Journal of Chinese Medicine Publications: Hove. Background: CIP • Chemotherapy agents reduce bone marrow activity • Chemotherapy induced pancytopenia (CIP) • White blood cell (WBC) – leucopoenia, neutropenia • Red blood cell (RBC) – anaemia • Platelet counts – thrombocytopenia • All have potential impact on: • Chemotherapy schedules (dose reduction, delays) • Survival (especially for curative or radical chemo) • Patient experience, quality of life • Cost Neutropenia (leucopoenia) • Severe neutropenia (SN) • Febrile neutropenia (FN) • Potentially life-threatening • Risk of serious infection, sepsis • Serious impact on chemo schedules, survival • 20% patients experience SN or FN after first cycle of chemo, rising to 30% during cycles 1 to 4 (Lyman et al 2011) • Cost to NHS of 1 episode of FN ≈ £2,300 – £3,500 • More if patient requires High Dependency Unit (neutropenic sepsis) Treatment for Neutropenia • Granulocytic-Colony Stimulating Factor (G-CSF) • Primary or secondary prophylaxis • Chemo regimens where risk of FN is >20%, or 10-20% • Not indicated for all chemo regimens, cancer types, or stages of cancer • Costly • Self-administered injection • Side effects: • Bone pain/aches, other musculoskeletal pain • Red, itchy skin; fevers, chills; fluid retention; breathlessness Chemotherapy-induced anaemia • High incidence, associated with: • Lung, gynaecologic malignancies • Platinum based chemo regimens (lung, ovarian, head & neck cancers) • New cytotoxic agents and intensive chemo regimens • Occurs in 19.5% chemo patients in cycle 1 • Rises to 46.7% in cycle 5 (NCCN 2012) • Treatments: • Blood transfusion • Erythropoiesis-stimulating agents (ESAs) • Iron supplementation and monitoring • Associated side effects and cost implications Thrombocytopenia • Least worrisome of the three conditions • Unless accompanied by heavy bleeding • Bruising, nose bleeds, bleeding gums, heavy periods • Usually untreated, other than observation • In some cases, platelet transfusion How can moxa help? • Used in classic and modern practice of Chinese medicine to: • Stimulate the immune system • Nourish blood • May have potential to reduce CIP, affecting • Incidence/severity of neutropenia, anaemia, thrombocytopenia • Reduce other side-effects of chemotherapy • Developing evidence base including: • • • • Laboratory research (animal) RCT Clinical observation, case studies Anecdotal Evidence base for moxibustion • Laboratory studies (animals) report improved immune cell function (see Zhang & Lao 2012; Wong & Sagar 2010) • Systematic review of clinical studies (China) reports: • Higher WBC, platelet counts than control • Reduced side effects, improved QoL • Conclusion: • “low level of evidence” demonstrating superiority of moxa over controls in management of CIP (Choi et al 2014) Evidence base • RCTs: • USA, ovarian: >leukocyte count; <incidence leucopoenia in intervention over sham (Lu et al 2009) • Portugal, colorectal: >WBC, absolute neutrophil counts, B cells, NK cells; <anxiety, depression in AcuMoxa group compared to no intervention (Pais et al 2014) • Clinical reports and case studies (UK) • Staebler – evaluation of 20 years clinical experience (2009) • Davies – case study of self-administered moxa on ST-36 (2013) Aims & objectives of this study • Primary aim • Assess feasibility of integrating intervention into a typical chemotherapy schedule: • 1) patient interest and participation • 2) adherence to daily procedure over long period of time • Secondary aims • Obtain first measure of effectiveness for reducing CIP • Obtain first measure of impact on completion of chemotherapy according to schedule • Collect preliminary data on reduction of other chemotherapy related toxicities and QoL • Assess acceptability to a) patients and b) oncology healthcare professionals (OHPs) • Monitor adverse events of moxibustion (safety) Study design • Phase 0 uncontrolled, observational single arm feasibility study • Single site • Aim to recruit 25 participants • Mixed methods • Quantitative data: adherence to moxa protocol; blood counts; completion of planned chemo schedule; QoL; patient self-management; safety • Qualitative: acceptability of intervention to patients (focus groups) and oncology health professionals (interview) Preliminary measures Adherence to moxa protocol Daily Moxa Diary Full blood count Patient records Completion of planned chemo schedule Patient records Chemo-related toxicities Patient notes Quality of life FACT-G, FACT- An & N (baseline, Cycle 1, Cycle 2, Cycle 3, Cycle 6 or final, EOT + 4 weeks Patient self-management Patient Activation Measure (PAM) Safety Participant report, Daily Moxa Diary Inclusion/exclusion criteria (abridged) • Patients, female or male, age 18 - 75 years • With breast, gynaecologic, colorectal cancers who are prescribed: • Radical or adjuvant chemotherapy in the early disease setting, or • 1st or 2nd line chemo if in the metastatic setting • About to commence a course of chemo for which G-CSF is not indicated • With a life expectancy of >6 months • Able to understand instructions for self-administration of moxa and carry out procedure • Able to give informed consent • Not suitable for patients with other severe medical problems, cognitive impairment, haematological cancer diagnosis, receiving GCSF Intervention: Step 1 • Meeting 1: Up to 10 days prior to first chemo • • • • • • • Explain concept of moxibustion Demonstrate procedure Obtain consent Teach how to light, use and extinguish moxa safely Teach how to locate Zusanli ST-36 Mark point with surgical pen Discuss importance of daily application on bilateral ST-36 (3 minutes each side) • Show how to record in Daily Moxa Diary • Supply moxa package • Supply support materials Intervention: Step 2 • Meeting 2: One week following meeting 1 • Participant demonstrates handling and application of moxa • Questions and concerns addressed • Given full pack of moxa supplies Moxa protocol • Moxa daily • Apply 3 minutes each point • Commence 7-10 days before starting chemo • Continue • Throughout full chemo schedule • Plus 3 weeks after end of chemo schedule • <10 minutes per day Credibility - three main concerns 1. Within research team 2. With oncology medical professionals: • ...moxibustion is a bit too far north...” • “We can get our heads around acupuncture, but moxibustion we just don’t get ...” 3. Potential participants • Participants not having regular acupuncture • Approaching patients “cold” • Introducing a new, novel intervention at a crisis point Establishing credibility in research team • Experiential, rather than theoretical understanding • Thorough understanding of procedure and challenges • Feedback improved our approach (moxa, lighters, extinguishers) • Increased confidence in explaining and demonstrating intervention • Additional ideas (mindfulness) Establishing credibility in NHS setting • Careful preparation to build positive attitudes • Rewrote protocol • • • • • Theory & evidence base for ST-36 and moxa Theory & evidence base for moxa for CIP Mechanisms of moxibustion Adverse effects of moxa Associated costs of treatments • Informal demonstrations • Formal meetings Supporting potential participants • Participant Information Sheet (PIS) • Summary of research evidence cited in protocol • Detailed instruction leaflet • Developed by award-winning inhouse information design team • Meets DoH “Information Standard” • Video demonstrating procedure Ensuring adequate participant support • All support tools available at http://www.ljmc.org/2_research/projects/moxa.html • Phone contact for any difficulties • Emergency number • Follow up with Health Improvement Practitioner (HIP) at each chemotherapy treatment To date: • • • • Successful first submission to ethics Recruitment opened 29 February 2016 8 participants to date Positive, constructive support from oncologists and chemotherapy nursing staff • Increasing interest from other OHPs • Publication: • de Valois B, Young T, Glynne-Jones R, Scarlett C, Staebler F (2016) Limiting chemotherapy side effects by using moxa. European Journal of Oriental Medicine, 8(3):29-39 Challenges • Recruiting patients 7-10 days before chemo starts • Amendment to protocol: recruitment up to the end of first chemotherapy dose • Competing with other studies • Working cross-team • Competing for the attention of busy clinicians to refer patients • Presence of HIP at all clinics • Bright flyers summarising inclusion/exclusion criteria • Stickers on patient notes • Building relationships with OHPs Dr Beverley de Valois Supportive Oncology Research Team Lynda Jackson Macmillan Centre Mount Vernon Cancer Centre Rickmansworth Road Northwood, Middlesex United Kingdom HA6 2RN Email: beverley.devalois@nhs.net
