Neoplasms + Disorders of the Breast Flashcards
Risk factors for breast cancer
- Menarche before age 12
- Old age of first full-term pregnancy, no pregnancies
- Menopause after age 52
- Breast mass- immobile, irregular
- Nipple retraction, bloody nipple discharge
MC type of breast cancer
Infiltrating Intraductal Carcinoma (IIC) 80%
- Infiltrating lobular (10%) frequently bilateral
- Paget’s disease of the nipple (1%) chronic eczematous itchy, scaling rash on the nipples and areola
- Inflammatory breast cancer (2%) red swollen, warm and itchy breast often with nipple retraction and peau d’orange (NO LUMP)
When should mammo’s begin?
every 2 years from age 50-74
Every 2 years beginning at age 40 if increased risk factors – 10 years prior to the age the 1’st degree relative was diagnosed.
- Clinical breast exam every 3 years in women age 20-39 years then annually after age 40
- Breast self-exam monthly beginning at age 20 – immediately after menstruation on days 5-7 of the menstrual cycle
Tx of breast cancer
- Segmental mastectomy (lumpectomy) followed by breast irradiation in all patients and adjunctive chemotherapy in women with positive nodes stage I and stage II with tumors less than 4 cm in diameter
- Anti-estrogen Tamoxifen is useful in tumors that are ER-positive – binds and blocks the estrogen receptor in the breast tissue
- Aromatase inhibitors are useful in postmenopausal ER-positive patients with breast cancer – reduces the production of estrogen
- Monoclonal AB treatment is useful in patients with HER2 positivity (Human Epidermal Growth Factor Receptor)
What clinical triad is strongly indicative of cervical cancer extension to the pelvic wall?
Unilateral leg edema, sciatic pain, ureteral obstruction
abnormal vaginal bleeding, most commonly postmenopausal
80% present with these sx = Cervical cancer
MC type of cervical cancer
- 80% are squamous cells and arise from the squamocolumnar junction of the cervix (transformational zone)
- HPV is 99% of the reason for cervical cancer, types that cause cancer are 16,18,31 and 33. Especially types 16, 18
- Associated with cigarette smoking
RF of cervical cancer
Multiple sexual partners, early age at first intercourse, early first pregnancy, and HPV positive
Dx of cervical cancer
Friable, bleeding cervical lesion on exam
- Biopsy of gross lesions and colposcopically directed biopsies are the definitive means of diagnosis
- Majority of cases (80%) are invasive squamous cell types usually arising from the ectocervix
Tx of cervical cancer
Resect and/or chemotherapy and radiation
- Stage 1: conservative, simple, or radical hysterectomy
- Stage 2 +: chemo +/– radiation
- 5-y survival– Stage 1: 85%-90% Stage 2: 65% Stage 3: 29% Stage 4: 21%
At what age should your patient receive their first PAP regardless of sexual activity?
First PAP at the age of 21 regardless of sexual activity (no pap indicated prior to that)
For women aged 21 to 29, all guidelines recommend only cytology screening every
3 years
For women 30 years and older, combination of cytology + HPV testing is recommended every
Every 5 years
Who should get annual cervical screenings?
- Annual screening is recommended for any high-risk groups (HIV infection, immunosuppression, or in utero DES exposure) or women who have treated in the past for CIN 2, CIN 3, or cervical cancer
What are the ACOG recommendations for discontinuing papsmear
- No cytology screening after total hysterectomy if surgery for benign condition. If surgery for CIN I, II, or III, then annually three times before discontinuing.
- Discontinue screening at age 65 for women who have had adequate recent screening. Adequate screening is defined as three consecutive negative cytology tests or two consecutive negative HPV/Pap co-tests in the 10 years before stopping, with the most recent test within 5 years
What are the PAP screening pathology report findings:
- ASC-US: Atypical squamous cells of undetermined significance
- LSIL: Low-grade squamous intraepithelial lesion, that is, mild dysplasia, CIN I
- HSIL: High-grade squamous intraepithelial lesion, that is, moderate to severe dysplasia, CIN II-III, carcinoma in situ
Which types of HPV have a high likelihood of leading to cervical cancer
HPV types 16, 18, and 31 are risk factors for cervical dysplasia, which can lead to cervical cancer
Women with negative cytology and HPV positive ⇒ both tests should be repeated in
12 months
Tx of ASC-US or LSIL, CIN-1
- Reflex HPV
-
If positive and at least 25 years old – colposcopy
- If negative or under 25 years old – retest in 1 year
-
If positive and at least 25 years old – colposcopy
Tx of HSIL, CIN-2, CIN-3, CIS
- Colposcopy
- Outside cervix – LEEP or cryotherapy
- Inside cervix – cone biopsy
- Squamous cell carcinoma ⇒ Resect and/or chemotherapy and radiation
When is the HPV vaccine recommended?
- Females and males – HPV vaccine is recommended at 11 to 12 years. It can be administered starting at 9 years of age, and catch-up vaccination is recommended for females aged 13 to 26 years who have not been previously vaccinated or who have not completed the vaccine series.
Can pregnant women receive the HPV vaccine?
Not recommended
males 22 to 26 years old, catch-up HPV vaccination is recommended if they are
men who have sex with men or immunocompromised (including HIV-infected males).
What is the dosing for the HPV vaccine if <15 yo
- < 15 years old: administer a two- rather than a three-dose vaccine series. In such patients, the two doses are administered at least six months apart
> 15 years old: the HPV vaccine is administered in
three doses at 0, at 1 to 2 months, and at 6 months
Immunocompromised should also have 3 dose vaccine series
