Q

Which patients should not have radiation therapy to the breasts and thus should have mastectomies (vs lumpectomies with rad)?

A

connective tissue disease, prior radiation to the chest or breasts
(tumors that are multicentric or with poor margins are not good lumpectomy candidates either)

Q

What is Stage I breast cancer?

A

T1NoMo (tumor 2 cm or less in greatest dimension)

21
Q

What is Stage II breast cancer?

A

Stage 2a

1) T1N1Mo (tumor 2 but 5 cm)

22
Q

What is Stage III breast cancer?

A

Stage 3a

1) T1n2mo (fixed, matted axillary nodes)
2) t2n2mo
3) t3n1mo
4) t3n2mo

Stage 3b
1) T4anyNmo (tumor of any size with direct extension to chest wall (not pec major) or skin

23
Q

What is stage 4 breast cancer?

A

anyTanyNm1 (distant mets INCLUDING supraclavicular nodes!!!)

24
Q

Patients who have had lumpectomy with radiation should undergo mammography of the affected breast how frequently?

A

every 6 months for 2 years, followed by yearly mammograms

25
Q

After mastectomy, women have a ___% chance of cancer developing in the remaining breast.

A

15

26
Q

An inflammatory lesion means that the breast cancer is stage

A

III

27
Q

T/F: In stage IV breast cancer, palliation with radiation and chemo is given, and no surgical procedure is performed unless the primary tumor is painful or infected.

A

True

28
Q

In stage III breast cancer, patients receive chemo (before/after) modified radical mastectomy.

A

both!!! (along with radiation post-op)

29
Q

What is the treatment of inflammatory breast cancer? What does histopath show?

A

histopath shows cancer cells invading dermal lymphatics and vessels with a large inflammatory component. Treatmet is 4-6 cycles of chemotherapy; then modified radical mastectomy, adjuvant chemo, and radiation to chest and regional LN basins

30
Q

A small 0.5 cm nodule in the suture line 5 years after modified radical mastectomy:

A

local recurrence until proven otherwise

31
Q

T/F: Local irradiation to a pathologic fracture inhibits fracture union.

A

FALSE. But it does control the cancer and prevent recurrence.

32
Q

The development of coma in any patient with a history of breast cancer should lead to the suspicion of

A

hypercalcemia (parathyroid hormone related peptide can be secreted by breast cancers; also must consider bony mets)

33
Q

T/F: Estrogen and progesterone receptor status of breast cancer is usually unreliable in preganncy.

A

True

34
Q

Lumpectomy can be performed in pregnant patients with breast cancer as long as they are in at least the ___ trimester.

A

3rd! Need post-op radiation…can be delayed until after delivery if in 3rd trimester, but otherwise should have mastectomy

35
Q

Gynecomastia is treated how in adolescents?

A

observation; typically spontaneously regresses

36
Q

T/F: A 6yo girl with a firm 1 cm unilateral breast mass should be biopsied.

A

observation! Excision or biopsy are contraindicated in such a patient because it would diminish or stop development of the breast by removing the breast tissue.

37
Q

Gynecomastia in a 50yo man is commonly associated with medications, including _______________-. Excision is only indicated if the enlargement fails to regress with cessation of meds.

A

diuretics (spironolactone), estrogens, isoniazid, marijuana, digoxin, alcohol abuse

38
Q

What are the borders of the axillary lymph nodes?

A

Axillary vein (apex), lat dorsi (lateral), pec major (medial), fifth to seventh ribs (inferior)

39
Q

What is Mondor disease and how is it treated?

A

Superficial thrombophlebitis, affecting the thoracoepigastric vein. Treated with NSAIDs and warm compresses.

40
Q

Mutation of BRCA-1 confers what risk of developing breast cancer?

A

60-80%

41
Q

What are the microscopic findings on biopsy of Paget’s disease of the nipple?

A

vacuolated cells

42
Q

What are common sites for metastasis of breast cancer?

A

Brain, bone, lungs, liver, and adrenal glands

43
Q

T/F: In comparing breast conversation surgery and mastectomy, there is no difference in possible recurrence rates, but mastectomy does confer better survival.

A

False!

Same survival, but mastectomy confers less chance of recurrence

44
Q

What drugs can be used for chemotherapy for breast cancer?

A

cyclophosphamide, methotrexate, fluorouracil, adriamycin

45
Q

What feature of gynecomastia makes it seem more likely benign than malignant?

A

breast tenderness

46
Q

What is the best treatment for breast cancer recurrence involving the chest wall following mastectomy?

A

radiation therapy (not surgery)

47
Q

What is a treatment that can be used for syphilis if a patient is allergic to penicillin?

A

doxycycline

48
Q

Lymph from the lower 25% of the vagina (below the hymen) is drained by which lymph nodes?

How about the upper 3/4 of the vagina?
