Transcription

1 Cancer Associated Side Effects: Complementary and Alternative Methods for Relief Don S. Dizon, MD, FACP Director, Oncology Sexual Health Clinic Gillette Center for Women s Cancers Massachusetts General Hospital Cancer Center

2 Scope Living beyond breast cancer: Approximately 220,000 diagnosed each year Living with breast cancer: Almost 3 million Breast cancer is not one cancer Genomic characterized subtypes Prognosis is variable HR-positive have a great prognosis HER2-positive do well with use of adjuvant trastuzumab Triple-negative: High risk of recurrence within first 3-5 years Risk factors for recurrence: Large tumor, node involvement, High recurrence score among others

3 Symptoms can come from various places Due to the diagnosis: Fear of recurrence Fear of death Due to treatment: Hot flashes Fatigue Depression Insomnia Sexual dysfunction

4 Where to turn Western medicine Complementary care Alternative treatment Family and friends Spirituality and Religion Community Aranda S, et al. Eur J Cancer Care 2005; 14:211; Kenne Sarenmalm E, et al. J Pain Symptom Mgt 2007;34:24. Image:

5 Complementary and Alternative Medicine (CAM) CAM therapies common 50-70% use Most patients do not discuss Complementary versus Alternative: Complementary = adjunctive treatments Alternative = treatment used independent of traditional medicine

6 CAM: Questions to consider What does it do? WHY would it do this? Interventions informed by theory are more effective than those that lack a theoretical basis Is there any evidence it works? Who is judge of the evidence? YOU ARE What are the RISKS? Nutrition aides Glanz K and Bishop DB. Ann Rev Pub Health 2010

7 Theoretical considerations Social Cognitive Theory Self-Efficacy Informs one s confidence in performing a specific behavior Integrative Medicine Theory Combining therapeutic modalities into a coherent protocol aimed at healing the whole

8 MODALITIES IN CAM

9 Accupuncture Needles, pressure, or heat at accupuncture points Traditional Chinese medicine Based on belief in QI (vital energy) that travels along meridians QI affects the spiritual, emotional, mental and physical condition http:

10 Accupuncture What the evidence suggests: 1. Accupuncture can alleviate pain as an adjunct to pain medications 2. Compared to sham technique, accupuncture helped treat pain associated with Ais 3. It can help reduce nausea and vomiting due to cancer therapy 4. It can help reduce hot flashes, improve sleep, and reduce depression (1) Cho, TY, etal.

11 Three A s: Anti-inflammatory: Omega 3 fatty acids Anticarcinogenic: tomatoes, saffron Nutrition Antioxidants: Pomegranate, red grapes, red wine, berries Rationale: Food enhances the immune system

12 Nurses Health Study Observational study 1999 analysis: 1982 women with BC. No effect on outcome based on intake of fruit, red-meat or grain. BUT: Women with MBC had lower mortality rate with vegetables, carotenoids, fiber intake 2005 analysis: 2619 women with BC. No effect on mortality Holmes MD, et al. Cancer 1999; 86:826; Kroenke CH, et al. J Clin Oncol 2005; 23:9295.

13 Women s Healthy Eating and Living Study 2005 report: 205 women with Recurrent BC Increased risk of BC with lowest intake of carotenoids 2007 report: Compared to intervention to observational groups followed for 7 years: No change in risk of BCE (17% in each, HR 0.96) No change in death (10% in each, HR 0.91) Rock CL, et al. J Clin Oncol 2005; 23:6631; Pierce JP, et al. JAMA :289.

14 Women s Interventional Nutrition Study Postmenopausal women with newly dx BC (n=2437) Intervention: reduction of fat intake to 15% of energy Results: Lowering fat intake associated with lower risk of BCE (10 versus 12%, HR 0.76, 95% ) ER negative cancer: HR 0.58, 95% CI ER positive cancer: HR 0.85, 95% CI No difference in Overall survival Chlebowski RT, et al. JNCI 2006; 98: 1767.

15 Exercise and Fitness Improves QOL Systematic review: + General QOL + Breast cancer-specific QOL + Improved cardiorespiratory fitness + Improved physical functioning + Improved fatigue? Improvement in survival McNeely ML, et al. CMAJ 2006; 175:34; Schmitz K, et al. Rec Res Ca Research 2011; 186:189

16 Mind-Spirit Interaction Multiple modalities: Meditation Yoga Tai-Chi Biofeedback Rationale: The mind can be used to influence health Impact on survival? Block KL, et al. Breast J 2009; 15:357.

17 Mind-Spirit Interaction: Impact on Survival? Maybe One observational Study from the Block Center for Integrative Care: Profiled 90 patients (Median age, 46) Treatment: Nutrition, fitness, and mind-spirit instruction Median survival 38 mos (95% CI, 27-48) 5-year SR: 27% (Control patients, 17%) Block KL, et al. Breast J 2009; 15:357.

18 APPROACHING SYMPTOMS

19 Hot Flashes Can interfere with daily function, quality of life, and sleep Side effect of medical therapies May be exacerbated by outside factors: stress, spicy food, alcohol, smoking, inactivity

20 Medications: Hot Flashes SSRI antidepressants: Venlafaxine (61% reduction vs 27% with placebo) Gabapentin: Dose 900mg/day Accupuncture: May be effective but studies not consistent Hypnotherapy: May be as effective as gabapentin Yoga: Sustained relief shown in a small study Loprinzi C, et al. Lancet 2000; 356:2059. Pandya K, et al. Lancet 2005; 366:818. Sunay D, et al. Accupunct Med 2011; 29:27; Kim DI, et al. Accupunct Med 2011; 29:249. MacLaughlan S, et al. J Clin Oncol 2011; abstr 168.

21 Hot Flashes Stellate Ganglion Block Requires OR: Injection into the AL aspect of transverse process of C6 Proof of success: temporary Horner s sign Pilot study of 34 patients Results: 64% improvement in hot flashes at week 1 1.7% increase in severity per week after Overall estimated benefit: 47% decrease at 24w Also noted: Improvement in sleep quality (4-fold improvement at week 24) Haest K, et al. Ann Oncol 2012; 23:1449.

22 Cancer-Related Fatigue Definition: Unrelenting sesnation of tiredness Disproportionate to level of activity Unrelieved by sleep or rest Physically debilitating Most prevalent symptom related to Cancer Affects 30-90%+ during treatment 20-40% still affected after treatment Esclanate CP, et al. J Gen Int Med 2009; NCCN Guidelines on CRF, 2010; Hickok JT, et al. J Pain Symptom Mgt 2005; ; Prue G, et al. Eur J Cancer 2006; 846.

23 Cancer-Related Fatigue Medical interventions are limited: Methylphenidate not effective vs placebo Erythropoietin stimulating agents CAM: Exercise Acupuncture Acupressure Massage Esclanate CP, et al. J Gen Int Med 2009; NCCN Guidelines on CRF, 2010; Hickok JT, et al. J Pain Symptom Mgt 2005; ; Prue G, et al. Eur J Cancer 2006; 846.

24 Cancer-Related Fatigue Medical interventions are limited. Methylphenidate: Opioid-induced sedation and cognitive dysfunction.??fatigue Bruera, et al: RCT of four interventions: N= 140 participants with advanced cancer and fatigue score of 4 or higher on screening Methylphenidate (MP) plus nursing telephone intervention (NTI) Placebo plus NTI MP plus control telephone intervention (CTI) Placebo plus CTI Esclanate CP, et al. J Gen Int Med 2009; NCCN Guidelines on CRF, 2010; Hickok JT, et al. J Pain Symptom Mgt 2005; ; Prue G, et al. Eur J Cancer 2006; 846; Bruera 2013; J Clin Oncol 31:2421.

25 Cancer-Related Fatigue Bruera, et al: RCT of four interventions: Telephone interventions: Nursing telephone intervention (NTI) Call by RN, standardized for content and duration including: Symptom assessment Review of medications Psychosocial support and patient education Control telephone intervention (CTI) Call by nonprofessional No psychosocial support or patient education Bruera 2013; J Clin Oncol 31:2421.

26 Cancer-Related Fatigue Bruera, et al: RCT of four interventions: Results: Median age, 58; 67% women Fatigue scores improved at day 15 in all subgroups None of the interventions were significantly better than placebo Bruera 2013; J Clin Oncol 31:2421.

27 Pain Affects over 70% of people living with advanced disease Different forms: Nociceptive Neuropathic Visceral Treatment must be multidisciplinary

28 Managing Pain Western medicine: Neuropathic pain: Tricyclic antidepressants, Anticonvulsants (ie, gabapentin), topic anesthestics, Opioids Nociceptive pain: Antiinflammatory agents, Opioids, Bisphosphonates (bone) Opioids are important but are NOT an answer by themselves

29 Insomnia Affects up to 75% of population Two types: Difficulty falling asleep Difficult staying asleep Western medicine: Cognitive behavioral therapy, sleep hygiene, Benzodizepines, Benzodiazepine receptor agonists CAM: Mindfulness, Yoga, Exercise, Massage Valerian officinialis: No effect seen in a randomized trial Barton DL, et al. J Supp Oncol 2011; 9:24

30 Insomnia Sleep Hygiene = Bedroom ONLY for sleep and sex Component of cognitive behavioral therapy in studies Results suggest it can improve insomnia and other issues (fatigue, anxiety, depression, QOL) Dirksen SR and Epstein DR. J Adv Nurs 2008; 6:664.

31 Dyspnea Usually not a symptom of lung metastases Dyspnea = shortness of breath (as perceived) Chest tightness, Air hunger, suffocations, breathlessness Cancer involving pleura or lymphatic channels can cause dyspnea Western medicine: Opioids (relieves dyspnea) Oxygen? CAM: Relaxation, Re-training

32 Nausea and vomiting Multifactorial etiologies Affects up to 30 and 60% of population Western medicine: Target CNS: dexamethasone Chemotherapy-related: serotonin 5-HT 3 receptor antagonists, substance P/neurokinin receptor anatagonists Bowel-associated: metoclopramide, lorazepam, octreotide

33 Can manifest physically and psychologically Very much real Subjective level of distress is the primary impetus for treatment Treatments: Medications (Anxiolytics, Antidepressants) Psychological support and counselling Mind-body interventions Exercise Distress

34 Conclusions Symptoms during and following treatment are common, but can be treated The options range from medication, medical therapies, and includes complementary and alternative approaches.

35 Conclusions Rule of thumb: If no theoretical risk, not financially burdensome, and you are interested, we should keep an open mind. Patients living beyond breast cancer should be informed about choices, but be cautious of where your information is coming from.

36 Conclusions We're just people. Cancer doesn't convert us into saints, martyrs, heroes, precious babydolls, or pity receptacles. We're just people.
