  23. 23. Surgery <ul><li>Breast conserving surgery </li></ul><ul><ul><li>Goal = curative surgery with better cosmetic appearance </li></ul></ul><ul><ul><li>Often called lumpectomy, wide local excision or partial mastectomy </li></ul></ul><ul><ul><li>Became alternative to mastectomy in 1980s </li></ul></ul><ul><li>Mastectomy </li></ul><ul><ul><li>Complete removal of the breast </li></ul></ul><ul><ul><li>Has become less extensive since 1970s </li></ul></ul>
  24. 24. Pathology from Breast Surgery <ul><li>Edges of breast tissue usually have ink placed </li></ul><ul><li>Under microscope, pathology doctor can ensure that no tumor at edge </li></ul><ul><li>Look at other features such as </li></ul><ul><ul><li>hormone receptors ER/PR </li></ul></ul><ul><ul><li>HER2/neu [invasive cancer only] </li></ul></ul>
  25. 25. Surgery for Nodes <ul><li>Increasingly, less is more </li></ul><ul><li>Sentinel lymph node biopsy – examines </li></ul><ul><li>node(s) most likely involved before </li></ul><ul><li>committing to axillary dissection </li></ul><ul><li>Sometimes more lymph nodes removed in axillary dissection [from underarm] </li></ul>
  26. 26. Pathologic Stage <ul><li>In early breast cancer, usually no treatment done before surgery </li></ul><ul><li>Surgical results give pathologic stage </li></ul><ul><ul><li>Best estimate of how far the cancer spread </li></ul></ul>
  27. 27. Role of Different Treatments <ul><li>Surgery </li></ul><ul><li>Medical treatment </li></ul><ul><ul><li>Hormone therapy </li></ul></ul><ul><ul><li>Chemotherapy </li></ul></ul><ul><ul><li>Targeted therapy </li></ul></ul><ul><li>Radiation treatment </li></ul>

  32. 32. Radiation Treatment <ul><li>Done after surgery and chemotherapy </li></ul><ul><li>Hormone therapy may be with or after radiation treatment </li></ul>
  33. 33. Who Decides What Treatments I Need? <ul><li>Ultimately, you decide </li></ul><ul><ul><li>Get advice and information from doctors </li></ul></ul><ul><ul><li>Consider your values </li></ul></ul><ul><ul><li>Get support for an informed choice </li></ul></ul><ul><li>Your Team : </li></ul><ul><li>Surgery = surgeon </li></ul><ul><li>Medical = medical oncologist </li></ul><ul><li>Radiation = radiation oncologist </li></ul>
  34. 34. Mastectomy or Breast Conserving Surgery? <ul><li>Mastectomy </li></ul><ul><ul><li>Complete removal of the breast </li></ul></ul><ul><ul><li>Has become less extensive since 1970s </li></ul></ul><ul><li>Breast conserving surgery (BCS) </li></ul><ul><ul><li>Goal = curative surgery with better cosmetic appearance </li></ul></ul><ul><ul><li>Often requires radiation to be equally effective as mastectomy for cure </li></ul></ul>
  35. 35. Both are equally effective for long-term cancer survival <ul><li>20- year old study NSABP B-06 shows long-term survival is equal for mastectomy and lumpectomy with radiation </li></ul><ul><li>Have to be candidate for both for this data to apply </li></ul><ul><li>Decision based upon understanding differences between the two </li></ul><ul><li>Some decision aids available to help </li></ul>Sources : http://1.usa.gov/NSABPB06_20Yrs http://bit.ly/JCO_BreastDecisionBoard
  36. 36. Differences in Early Stage Breast Cancer * Some patient with lymph node involvement may need radiation § Varies based upon several factors (age, tumor type + size, etc.) Factor Mastectomy BCS Keep my breast No Yes Avoid radiation Usually yes* Usually no § Less treatment time Depends how you define it ‘ Do everything’ Yes No ‘ Less (surgery) is more’ No Yes Recurs in breast Lowest Slightly higher Survival/Cure Equal
  37. 37. Considerations in Making a Decision <ul><li>Think about what you value more </li></ul><ul><ul><li>Quality of Life : Breast preservation, sexuality, convenience, side effects of treatments </li></ul></ul><ul><ul><li>Tumor control : Reducing risk of recurrence, overall cure </li></ul></ul><ul><li>Ask for specific information about risks/benefits from your doctors </li></ul><ul><li>Discuss your preferences with your social support and doctors </li></ul>
  38. 38. Why do I see a radiation doctor? <ul><li>Choice of surgery may dictate need for radiation treatment </li></ul><ul><li>May help with making informed choice </li></ul><ul><li>Ask your surgeon </li></ul>
  39. 39. Surgery <ul><li>Many different techniques </li></ul><ul><li>Ask your surgeon about treatment options, risks and benefits for you </li></ul>
  40. 40. Radiation Treatment for the Breast <ul><ul><li>What to bring to your doctor </li></ul></ul><ul><ul><li>How it works </li></ul></ul><ul><ul><li>Treatment approach: whole vs. partial </li></ul></ul><ul><ul><li>Planning radiation treatment </li></ul></ul><ul><ul><li>Time commitment </li></ul></ul><ul><ul><li>Side effects during and after treatment </li></ul></ul>
  41. 41. What to Bring <ul><li>Information about you and your medical history </li></ul><ul><li>Reports from </li></ul><ul><ul><li>Surgeon, surgery </li></ul></ul><ul><ul><li>Mammogram, ultrasound, MRI (bring on disc too!) </li></ul></ul><ul><ul><li>Biopsy, surgical pathology reports </li></ul></ul><ul><li>Friends/family if helpful </li></ul>
  42. 42. What is radiation? <ul><li>Energy from particles moving in space </li></ul><ul><li>Ionizing radiation = enough energy to affect </li></ul><ul><li>matter </li></ul><ul><li>X-ray = high energy light = photons </li></ul><ul><li>Other types: Electrons, Protons, Neutrons </li></ul>Source : http://bit.ly/IonizingRadiation
  43. 43. How does radiation work? <ul><li>Radiation goes through cancer cell </li></ul><ul><li>Damages critical cell machinery for growth </li></ul><ul><li>Different ways cells can die </li></ul>Source : http://bit.ly/ROWikibookRTDNA http://bit.ly/ColemanRadiationSensitivity http://bit.ly/ROWikibookCellDeath
  44. 44. How do I know it worked? <ul><li>In breast cancer, usually you don’t know for sure </li></ul><ul><li>Radiation usually used after surgery… </li></ul><ul><ul><li>Nothing detectable </li></ul></ul><ul><ul><li>Treating possible cells left behind </li></ul></ul><ul><ul><li>No good test to show radiation worked </li></ul></ul>
  45. 45. ‘ No News Is Good News’ <ul><li>Can’t prove radiation worked, but time is the test </li></ul><ul><li>Each visit your doctors don’t find any evidence of recurrence, risk goes down </li></ul><ul><li>Self-breast exam, clinical exams and future imaging are important after treatment </li></ul>
  46. 46. Why do radiation if you can’t tell it worked for me? <ul><li>For each woman, it’s not possible to be sure, but… </li></ul><ul><li>Sort of like an insurance policy to reduce your risk of recurrence after lumpectomy </li></ul><ul><li>Ask your doctor what that risk may be </li></ul>
  47. 47. Treatment approach: Whole vs. Partial <ul><li>Standard treatment has been whole breast </li></ul><ul><ul><li>Noninvasive treatment of breast instead of surgery </li></ul></ul><ul><li>Many patients’ chance of recurrence is at surgical site, so can treatment be focused there? </li></ul>
  48. 48. Why Partial? <ul><li>Goal = treat less breast with equal or better: </li></ul><ul><ul><li>cancer control </li></ul></ul><ul><ul><li>cosmetic appearance </li></ul></ul><ul><ul><li>normal tissue injury </li></ul></ul><ul><ul><li>Convenience </li></ul></ul><ul><li>Reason = some patients have no cancer cells anywhere else except near surgical site </li></ul>
  49. 49. Partial breast treatment <ul><li>Different approaches (external and internal) </li></ul><ul><li>Typically 10 treatments in five days </li></ul><ul><ul><li>Twice a day, separated by 6 hours </li></ul></ul>
  50. 50. Who is suitable for partial breast irradiation? Source : http://bit.ly/ASTRO-APBI-Consensus Factor Criterion Age 60+ years old BRCA 1/2 Not present Tumor 2 cm or less Margins Clear/negative by 2mm Vascular invasion No Type Invasive ductal, other favorable ER Status Positive Multifocal/centric No (unless <2 cm under microscope only) Nodes Negative or only on immunohistochemistry Node surgery Yes, either axillary sentinel node biopsy or axillary dissection
