Q

prostate cancer: PSA

A

-prostate specific antigen- PSA
-predication of the course of ds
-prediction of stage of ds
-follow up after tx
-controversial in screening!!!
-Not recommended screening unless suspicion!
-only order if palpate nodule, urinary symptoms etc
-Correlation with size of prostate
-Elevation in Prostate Carcinoma and Benign Prostatic Hypertrophy (BPH)
-Increased after exam or biopsy
-If elevated after 2-3 months: concern for cancer
-excellent for post cancer screening and removal

Q

PSA screening criteria

A

men aged 55-69 years - cat C (only ordere with clinical indication)
-1 test
-many pros and harms of testing
-based on family hx, race/ethnicity, cormorbid medical conditions, pt values ab benefits and harms of screening and tx specific outcomes
-dont screen men who do not express preference for screening

70+ men- dont screen (cat D)
-digital rectal exam elevates PSA -> send script

Q

evaluation of low testosterone in males

A

Checks labs for LH levels, and serum testosterone
- If low testosterone and low LH → pituitary or hypothalamic problem (secondary hypogonadism)
- If low testosterone and high LH → secondary cause of low androgen/primary hypogonadism
- R/O cancer tx, alkylating agent or testicular radiation, trauma, mumps orchitis

-test low and LH and FSH not elevated -> secondary hypogonadism -> check T4, cortisol, prolactin, ferritin, transferrin saturation, MRI
-test, LH, FSH elevated -> primary hypogonadism -> genetic testing for klinefelter syndrome

Q

partial androgen deficiency tx

A

Treatment = testosterone replacement therapy
-Replacement increases muscle mass, increase bone mass, protect against falls & reduces bone fractures
-Side Effects: pathogenesis of BPH & prostate cancer, decrease sperm count, dyslipidemia, increased CAD

Q

cervical cancer screening: pap smear

A

-21-29- every 3 years with cytology alone

Q

pregnancy test

A

Urine hCG- 14 days post conception -> implantation!
-first urine in the morning= most accurate with highest concentration

Beta hCG- 8-11 days post conception
-doubles every 1.5-2 days for the first 8 weeks
-order this to r/o preg in ER (more accurate test)

at 8 wks: heart beat!

Screen for fetal abnormalities:

-AFP
-hCG
-PAPP: pregnancy associated plasma protein
-nucal US

2nd trimester work up “Quad”-
-AFP
- hCG
- inhibin A
-estriol

Q

fetal DNA

A

-testing maternal serum
-does not tell of neural tube defects
-gender
-tells you about chromosomal abnormalities***

recommended for:
-mother > 35 yo(higher chance of chromosome abnormalities
-US suggests abnormalities
-previous pregnancy
- abnormal labs

Q

ectopic pregnancy

A

-1.3 – 2% of pregnancies
-Maternal death
-MC fallopian tubes -> rupture -> death

Risk factors/increased in:
-Tubal damage ( infections)
-Smoking
-Infertility
-Previous ectopic pregnancy

Symptoms:
-mostly asymptomatic (25% sx)
-lower abdominal pain
-vaginal bleeding
- adnexal mass (palpable)

Work up:
-hCG (abnormally high)
-US
-medical tx: oral methotrexate
-surgical intervention
- If a positive pregnancy but scan of the uterus does not show a fetus, assuming ectopic until proven otherwise**

17
Q

spontaneous abortion

A

-miscarriage in 1 - 5 PREGNANCIES*******
-10-20% of all pregnancies < 20 weeks
-increased risk - maternal age, previous miscarriage, smoking, ETOH, drugs
-50% occur secondary to chromosomal abnormalities
- considered recurrent if 3 or more consecutive
-1-5% recurrent

-8 weeks should have heart beat

18
Q

trophoblastic tissue

A

-Disease process of the placenta: Implantation of embryo -> produces abnormal tissue rather than fetus
-Can have malignancy
-Dx: No fetal heart beat, ELEVATED hCG, shortened hCG doubling time
-Dissection and excision: follow post surgical hCG to ensure its no longer elevated -> possible metastases to other location (ex: lungs)

TX IS SURGICAL EXCISION NOT METHOTREXATE

19
Q

preeclampsia/eclampsia

A

-increased morbidity and mortality
-preeclampsia- HTN & proteinuria (2-8%)
-eclampsia- above plus seizures

Also occurring: HELLP syndrome
-coagulapathies (low platelets)
-elevated LFTs
-renal failure
-cerebral ischemia (HTN)
-symptom control till delivery

HELLP:
- hemolysis
- Elevated Liver enzymes
- Low Platelets

20
Q

HELLP syndrome

A

-Hemolysis
-E&L- elevated liver enzymes
-L&P- low platelets (thrombocytopenia)
-27-36 wks
-can occur with preeclampsia
-bruising !!

21
Q

fatty liver in pregnancy

A

-sx: Nausea & Vomiting, RUQ pain, lethargy
-@ 36 weeks
-DX Liver Biopsy
-AST>ALT, elevated bilirubin, hypoglycemia, hyperuricemia, elevated PTT, elevated PT, decreased fibrogen

22
Q

A

“HI UTOPIC infertility (no kids = utopia)”

-Hormonal
-Iatrogenic
-Uterine
-Tubal
-Ovarian
-Psychosocial
-Immunological
-Cervical

23
Q

hystersalpingogram

A

-occlusions at isthmus of both fallopian tubes
-test for infertility blocks

24
Q

breast screening criteria

A

-women 50-74- every other year screening
-women 40-49- high risk
->75 or older- no screening
-you can screen anyone with a hx or hx of cancer

25
Q

breast cancer: incidence and risk factors

A

-1 in 8 women
-1% in males
-spiculated nodule on mammogram

Risk factors:
-Increased age
-Family history
-Hormonal Hx
-Clinical density -> US bc hard to see
-Obesity
-ETOH

26
Q

management algorithm for pts with abnormal mammograms

A

abnormal screening mammogram = do a diagnostic mammogram +/- breast US
- normal/bengin result: return to annual screening
- probably benign: repeat 6 months
- high suggestion of malignancy: percutaneous bx

27
Q

female infertility: indications and timing of infertility evaluations

A

when to initiate infertility eval:
- under 35 with no risk factors: after 12 months of attempting
- 35-40: after 6 months of attempting

initiate eval upon presentation:
- 40+ yrs
- no period (amenorrhea)/oligomenorrhea
- suspected tubal/uterine ds
- hx of chemo/radiation, endometriosis
- male parter w hx of surgery, mumps, impotence, chemo/radiation

tell pt to track cycle!!!!

28
Q

menopause

A

suspect in females over 40 with:
- irregular periods
- negative hCG
- hot flashes

no period over 12 months + over 45 = clinical menopause

under 45 and no clear dx: workup for endocrine issues with TSH, FSH, prolactin -> normal = early menopause

29
Q

breast cancer: tx

A

-Breast conserving surgery
-Radiation
-Mastectomy
-radical mastectomy- takes lymph nodes too and some of pec
-Chemotherapy
-Hormone Therapy

30
Q

breast cancer prognosis

A

-Tumor size
-Axillary node involvement
-Histological type
-Histological grade- disorganization
-Lymphatic & vascular invasion
-Biomarkers

31
Q

breast cancer labs: tumor markers

A

-not genetic -> we are testing the tumor

Estrogen Receptor:
-is tumor growing in response to estrogen
-Estrogen dependent
-70% of breast cancer (MC)
-Favorable prognosis

Progesterone Receptor

Endocrine treatments can include Selective ER modulators:
-Tamoxifen- blocks estrogen receptors
-Ovarian ablation: reduces estrogen production

32
Q

labs: HER-2

A

-Chromosomal gene abnormality: Cell proliferation & survival gene
-10%- 15% have gene amplified
-More aggressive and poor outcome
-Focused therapy with trastuzumab (herceptin) -> Cardiotoxic (dilated)
-this drug stops cell proliferation while you do surgery/resection/chemo
- trastuzumab (herceptin): blocks HER2 receptors

33
Q

breast cancer biomarkers

A

-none currently that are elevated in all pts
-other markers can be elevated in metastatic ds
-other markers can also rise during chemo

34
Q

hereditary breast and ovarian cancer: BRCA 1 and BRCA 2

A

Hereditary mutation:
-60-80% occurrence of Breast & Ovarian Cancer
-Tumor suppressor genes / gene stability deleted
-BRCA gene typically suppresses cancer
-BRCA 1 lifetime ovarian cancer: 15-60%
-BRCA 2 lifetime ovarian cancer: 10-27%
-increased melanoma, prostate CA, and pancreatic CA risk

35
Q

Indicators of BRCA 1 and 2 Mutation Risk:

A

-Early Breast Cancer onset < 50 yrs
-bilateral cancer
-concurrent Breast and Ovarian cancer
-Autosomal dominant inheritance pattern
-Breast Cancer in male relative

36
Q

hereditary breast and ovarian cancer management

A

If BRCA 1 or 2 mutation present:
-Intensive Screening: MRI
-Chemoprevention
-Mastectomy: preventative measure
-Prophylactic oophorectomy after childbearing: Decrease risk of Breast and Ovarian cancer
