  1. Which quadrant is the most common site or breast ca
    upper outer quadrant and generally left
  2. # 1 breast cancer is
    infiltrating ductal carcinoma
  3. Where does breast cancer met to
    blood to skin, bone, liver, lung and brain
  4. What is breast dose following a lumpectomy
    50 and boost scar 20
  5. Is lobular carcinoma in situ that originates in the lobules (milk producing glands at the end of the milk ducts) considered a true cancer
  6. What is a sentinel lymph node biopsy
    uses dye or radioactive tracer to id the 1st chain of ln drainage in the breast. If the node is positive to disease, a full axillary disection can be done
  7. 1 in how many women will get breast cancer?
    1 in 8
  8. What is the most common disease of the breast
    fibrocystic disease which is a benign condition, the most common breast cancer is infiltrating ductal
  9. List some risk factors for breast cancer
    • family history and BRCA 1 and 2
    • History of benign breast disease
    • oral contraceptives
    • HRT (estrogen)
    • alcohol and tobacco
    • women who give birth late or nulliparity
    • early period
    • late menopause
    • previous radiation
  10. What is the worst breast cancer to have
  11. What is Her2Neu
    protein to see how aggressive tumor is. If negative it means it is aggressive
  12. What age should patients get a mammogram
    baseline at 35  and everyother year starting at age 40 and then every year after age 50
  13. What are 2 common chemo drugs for breast cancer
    • CAF cytoxan, adriamycin, methotrexate- very common to lose all hair
    • CMF- cytoxan, 5 flourouracil, methotrexate- no hair loss
  14. What is an endocrine therapy for breast cancer
  15. List the staging for breast cancer
    • Tis-carcinoma in situ
    • T1-2cm or less
    • T2-more than 2 cm but not more than 5
    • T3-greater than 5cm
    • T4-any size with direct extension to the chest wall or skin
  16. What is an example of radiation tangent borders
    • superior-1st intercostal space right at the clavicular head
    • inferior- 1-2 cm below inframammary fold (rt under breast
    • medial- midline-suprasternal notch to the xiphoid process
    • Lateral- mid axillary line
    • include 1-2 cm of lung
  17. What is the most common sign for breast cancer
    painless lump, you want a mobile one that is a good sign
  18. What are some side effects of radiating the breast
    • skin changes peak at about 2-3 weeks after tx
    • dryness and redness after 30GY
    • Dry desquamation after 40 GY
    • Moist desquamation after 40 GY
    • fatigue
    • cardiac effect
    • pulmonary effects like radiation pneumonitis
  19. The pathologic staging system for breast cancer incorporates
    LN staus
    Tumor extent and /or
    distant mets
    All 3
  20. Chemotherapy for breast cancer may consist of
    drug therapy
    endocrine therapy and /or
    • drug therapy and
    • endocrine therapy
  21. In treating a breast cancer pt via tangential fields plus an electron boost, the usual total dose to the tumor bed del thru a std fractionation schedule is
    60-66 Gy
  22. What is the technique that may be used to adequately irradiate the imc LN on a pt with left breast cancer and simultaneously del the least cardiac dose is
    anterior photon-electron fields, equally weighted, 50 Gy in 5 weeks
  23. When an immobilization device is needed , is it best to first determine the
    beam orientation and then build the device
  24. In most breast ca txs, field matching is a problem between which fields
    the internal mammary and tangential fields and between the tangential and scv
  25. The couch angel necessary to avoid beam divergence from the tangential fields into the scv field depends on the
    length of the tangential field in the direction of the scv field and the distance
  26. To avoid beam divergence from the tangential fields into the scv field, the foot of the couch
    is turned away from the collimator
  27. A boost is sometimes del to the tumor bed in breast cancer using
    an electron beam or an interstitial implant
  28. The Internal mammary LN are sometimes treated in a
    separate field using a photon and an electron beam included in the tangential fields
  29. Cardiac toxicity from breast irradiation is
    A. sometimes a serious problem
    B. Never occurs because the heart is outside of the fields
    C. Occurs following 10GY
    D. Never heard of
    (this multiple choice question has been scrambled)
  30. The PAB is intended to irradiate the
    level 3 axillary nodes
  31. For estrogen receptor positive cases, an antiestrogen may be used to maintain remission known as
  32. When using a breast board for positioning, the optimal incline angel is influenced by
    the slope of the pts chest
  33. When the SCV is treated along with opposing tangents, the scv field is best treated using
    1/2 field technique
  34. The acceptable amt of lung tissue included in tangential breast fields is in order to decrease the chance of latent
    lung fibrosis
  35. Ductal carcinoma in situ (DCIS) is classified as state
  36. A sentinel ln biopsy involves the injection of a blue dye and radioactive
    Technetium 99m
  37. If Scv nodes are positive, what is the staging
    automatically stage IV
