3 A Diagnosis of Advanced Breast Cancer Leads To Many Immediate Questions How am I supposed to deal with this? What about my family? Is this a death sentence? How long do I have to live? How am I going to afford this? 3

4 Many Challenges The stress of a diagnosis Far-reaching decisions regarding immediate care Family and friends considerations Effect on your job Finding time to think Obtaining reliable information Finding the right healthcare team/ seeking additional opinions 4

5 OUR GOAL

6 What makes it easier to deal with this.. Knowledge

7 Knowledge.about medical issues.about choosing a treatment team that will provide the best medical care, respect your participation in decision making, and serve as your advocate.how to find help dealing with the psychosocial issues

8 Let s start with medical knowledge Leading websites offering evidence based information Advocacy groups websites

9 Knowledge about the disease: Basic information Goal of treatment is usually control rather than cure There are more treatment options than for most other types of cancer And the list of options continues to grow Treatment options depend upon the type of breast cancer

10 Types of breast cancer Luminal or estrogen receptor positive breast cancers HER2 overexpressing ( positive ) breast cancers Triple negative breast cancers Question: should first recurrences be biopsied to verify the primary and to determine the type?

11 Luminal (ER+) breast cancer Commonest type Breast cancers which depend on estrogen for their survival Identified by the production within the cancer cell of either the estrogen receptor protein (ER) and/or the progesterone receptor (PR)

12 Treatment options for ER+ disease: Estrogen blockers (endocrine Rx) Rationale starve tumors of estrogen Postmenopausal estrogen made by adrenals Options Anastrazole or letrozole Exemestane with or without everolimus Fulvestrant Tamoxifen Megestrol Less often (male hormone, hi dose estrogen)

13 Treatment options for ER+ disease: Estrogen blockers (endocrine Rx) Premenopausal estrogen made by adrenal glands and ovaries Options Tamoxifen Ovarian suppression or removal Once ovaries removed or suppressed, same options as for postmenopausal women

14 How are these used? Choice of endocrine therapy depends upon prior endocrine therapies, menopausal status, MD and patient preference Continue one endocrine therapy until it stops working or toxicity Duration of response widely variable If endocrine therapies are no longer effective, consider chemotherapy

15 ER+ disease: When to switch to chemotherapy Endocrine therapies can take 3 months or more to take effect Consider chemotherapy If disease is rapidly progressive and we re not comfortable waiting 3 months to evaluate benefit If the disease is clearly resistant to endocrine therapy

16 When to switch to chemotherapy Question I hear a lot at diagnosis why aren t you giving me the strongest chemo and endocrine therapy together to knock this thing out?

17 Why not treat ER+ disease as Goal is control aggressively as possible? No evidence that more aggressive treatment prolongs life any more than less aggressive Endocrine therapy can work just as well as chemotherapy and often with less toxicity Approach: use treatments sequentially

18 Most effective use of endocrine therapy This is an area where the experience of the medical oncologist is key Some examples.

19 Endocrine therapy: where the experience of the oncologist counts When to switch therapies Correct use of tumor markers (CA2729, CA 15-3) Evaluating response to endocrine therapy too early Differentiating healing on the bone scan from progressive disease Use of endocrine therapy in the setting of organ metastases (liver, lung) Rare situation where endocrine therapy may be added to chemotherapy Frequency of radiologic evaluations Use of endocrine therapy with reportedly ER- disease

20 Endocrine therapy - Research Understanding resistance Exploring ways to overcome resistance Blocking other biologic pathways that may be stimulating cell growth One treatment that accomplishes this goal is already on the market (Afinitor) Many others are in development

21 HER2 positive breast cancer What HER2 positive means Biology of HER2 positive disease More rapidly growing without treatment Tend to respond well to chemotherapy Tend to respond less well to endocrine therapy Options for systemic treatment If ER+, endocrine therapy Chemotherapy (usually with a HER2 blocker) Blockers of the HER2 protein

22 Commercially available blockers of the HER2 protein Trastuzumab Pertuzumab TDM-1 Lapatinib

23 Where the experience of the oncologist counts When is it appropriate to use endocrine therapy alone or with a HER2 blocker? If chemo and a HER2 blocker are going to be used which chemo? Which HER2 blocker? When to stop chemotherapy and continue with a HER2 blocker alone

24 HER2 positive disease: Some comments Brain metastases a bit more common But tend to be treatable and compatible with significant duration of life Wide variation in responses to treatment Long term response not unusual

25 HER2 positive disease Probably better understanding of this type than the others Tremendous research Understanding variations in response and resistance to better choose treatment Development of new HER2 blockers Combining HER2 blockers with blockers of other pathways stimulating growth of cells

26 Triple negative breast cancers Wastebasket term Right now the only conventional options involve chemotherapy Bad rep both deserved and undeserved

27 Triple negative disease: Where the experience of the oncologist counts How to choose the sequence of chemotherapy drugs When to use single agent chemotherapy vs combination How to deal with specific situations Brain metastases Low volume metastatic disease Resecting the primary tumor in the setting of metastatic disease

28 Triple negative breast cancers Tremendous research Identifying subtypes of triple negative disease Identifying abnormal pathways stimulating growth within the cells and developing drugs to interfere with these pathways (targeted therapies) Expectation very quickly our understanding of triple negative disease will increase and our ability to treat will improve dramatically

29 Metastatic disease understanding the literature Most studies use as the primary endpoint progression free survival (PFS) PFS is defined as the time from the start of a treatment to progression of disease or death from any cause

30 Concept of median PFS Median the point at which 50% of people remain without progression and 50% of people have experienced progression Keep in mind: Very few people are at the median Just one measure of benefit of treatment Misses a lot of important data

31 Proportion Progression-Free EMILIA * (TDM4370g) Phase III Progression-Free Survival (PFS) by Independent Review M Median,Months Events, n Cap + Lap T-DM Stratified HR=0.65 (95% CI, ) P< Time, Months Number at risk by independent review: Cap + Lap T-DM Unstratified HR=0.66 (95% CI, , P<0.0001) Cap=capecitabine; Lap=lapatinib Verma S, et al. N Engl J Med 2012;367: [incl. Supplementary Appendix] 2013 Genentech, Inc. All rights reserved. *Genentech/Roche Sponsored Study

32 Another measure of response - Shrinkage or stabilization of disease Evaluating tumor response Complete remission Partial remission Stable disease Progressive disease Am I in remission? Can refer to above definitions Clinical benefit complete + partial + stable disease

33 How to choose the optimal oncology team? One person s opinion Very important that you have on your team an oncologist with expertise in treating people with metastatic breast cancer Two models to ensure that you are getting the best care Have as your primary oncologist a physician whose practice is entirely or almost entirely devoted to breast cancer and who is respected for her/his expertise in your community Have a consulting breast oncology expert work with your own medical oncologist

34 How to choose the optimal oncology team? How to identify a breast oncology expert Ask your current medical oncologist or your primary care physician/gyn Call a regional office of an advocacy group Go to a National Cancer Institute-designated Comprehensive Cancer Center For your consultant To recommend a breast oncologist in your area

35 Your team is more than your medical oncologist Making the most of Your office visit Key Members of Your Healthcare Team Oncologist Other medical specialists Primary Care Physician Nurses/Physician Assistants Social Worker Spiritual counselor Financial counselor Office assistant Bring a list of your concerns and questions Be concise even if you need to practice Take notes Take someone with you if you can Get copies of your test results 35

36 Your team as your advocate This is about YOU Be respectful of your healthcare professionals BUT try not to be intimidated Recognize that YOU are the priority and the consumer Recognize that you have rights Your rights as a patient Be educated about your condition, options for Rx and HONESTY regarding anticipated outcomes of proposed treatments Ask for a recommendation Have your questions answered Challenge in a respectful way Ask for help in arranging a second opinion Ask for help dealing with emotional or social issues Ask for information about financial concerns

37 An important issue: Clinical trials As health care workers we encourage participation in clinical trials when appropriate Why consider participation Helps society May offer access to a new effective therapy

38 Clinical trials: Some questions to consider What is the scientific rationale? What are the specific treatments being investigated? What would be the treatment recommendation if I didn t participate? What are the possible toxicities? What implications for my quality of life? Required visits, bloodwork, frequency of scans, etc Are any doors closed if I don t participate now or if I do?

39 Another important issue: second opinions Why consider Your oncologist may recommend You may feel more comfortable Access to a clinical trial Your oncologist feels there are few options left and you are interested in further therapy

40 Second opinions Where to go Someone with recognized expertise in breast cancer treatment and access to clinical trials Could be a NCI designated Comprehensive Cancer Center or a regionally recognized expert How to find Ask your oncologist to recommend and help gather records Ask people involved in a local advocacy group Going to an NCI-designated Comprehensive Cancer Center

41 Newly diagnosed with metastatic disease: Psychosocial issues

42 Social issues What do I tell my family What do I tell my friends What do I do about work

43 Dealing with social issues Know that you are not facing this alone Help in dealing with some of these issues Significant other, close friend, close family Social worker at MD office or hospital Specific knowledge about what to tell children, employee rights, etc Work with you in how to address important social issues Support groups

44 Difficult but practical issues Wills, having someone know where important papers are and what if any personal choices you have Think about medical directive Legacy for loved ones Pictures Experiences Messages for future important events

45 Some of the spiritual issues brought up by this diagnosis What do I want to accomplish in my life How do I want to spend my time and resources How long will I live How do I deal with my family and loved ones if I reach the point of saying enough Do I have fears and, if so, how to deal with them Living with uncertainty Of physical discomfort Of death

46 Facing these and related issues Get information and support from your medical team be sure to share your questions and concerns Consider frank dialogue with family and friends Seek help from a social worker or other therapist (including meds for anxiety, depression, sleep if indicated) Speak with religious / spiritual leaders Support groups (medical, spiritual) Journaling Quiet meditation Give yourself permission to let go and do things you like to enjoy

47 Some resources on the Web for support and information 47

48 Summary From the medical viewpoint Breast cancer is very treatable for many people Tremendous research efforts are underway leading to major changes in the way we approach breast cancer and the expectation that outcomes will continue to improve

49 Closing thought: We can t control the wind, But we can adjust the sails
