1st deg relatives with colon CA
h/o other CA (breast, ovarian, endometrial)
Familial polyposis (gardners, familiar adenomatous polyposis highest risk (5Q- gene abnormality)
Hereditary non polyposis colono CA (HNPCC)
Adenomas –> next colonoscopy in 3 years if > or + 1 cm or 3 or more polyps
<60 1st degree relative–> 40 yrs + every 5 yrs
2 1st degree relatives –> 40 yrs + every 5 yrs
1 1st degree relative –> 40yrs + every 10 yrs
Decrease risk colon CA:

Risk factors for breast CA
Highest risk: Female >50yo Personal hx breast CA strong Fhx pre-menopausal breast CA Genetic BRCA 1+2
Other risk factors:
personal h/o ovarian CA or endometrial CA
dense breasts
OCPs>15yrs.
Screening:
- women >50yrs OR <5-10yrs prior to age in 1st deg relative w/ breast Ca and then q 2 yrs
- 10% of breast Ca found on PE is missed by mammogram
- BRCA 1: Chrom 17; breast, ovarian cancer in women and prostate cancer in men. High penetrance. Other family members should be aware. (MRI every year)
- BRCA 2: chrom 13
- TP53 mutation: breast cancer with other cancers in family at younger age; brain, leukemias, and sarcomas.
Breast CA screening
- women >50yrs OR <5-10yrs prior to age in 1st deg relative w/ breast Ca and then q 2 yrs

Local breast diseas in situ (??all w/in basement membrane??)
tx - lumopectomy + RT or mastecotmy
tamoxifen (pre-menopause)/aromatoase inh (post-menopausal). if ER receptor +
Lobular CA in situ
observation or if ER+ -> tamoxifen (???pre)/aromatase (post menopause???)

Locally invasive dz involving skin or chest wall
chemotx followed by mastectomy + tamoxifen/aromatose inh if ER receptor+
Most important prognostic factor in breast CA?
LN invovlement>tumor size>receptor+>grade
Adjuvant therapy for LN(+) dz
-Premenoapuse -
ER+ -> chemo + tamoxfen
ER- -> chemotx
HERR-2 (+)–> + trastuzumab
-Post menopause -
ER+ -> chemotx + aromatase inhibitors
ER - -> Chemotx
HERR-2 + –> trastuzumab
Adjuvant therapy for LN neg dz >0.5 cms
premenopausal - ER+ tamoxifen + HERR-2 += trastuzumab
Post menopausal - ER+ aromatase inhib + HERR-2 + trastuzumab
???When to use chemo tx in breast CA
????Tumor size>1cm, high grade
if <1cm NO CHEMOtx
Types of breast CA
Intraductal 80%
Lobular 10%
Other 10%
Excision of mass with free margin +RT =
Modifeid radiacla mastectomy + RT
If sentinel LN bx +
Further LN dissection
If sentinel LN bx neg
no further LN dissection
If LN +
Adjuvant tx : Chemotherapy +/- tamoxifen (pre menopausal), aromatose inh (post menopausal)
tamoxifen/aromatase inhib used also?
LN neg pts w/ ER+
- Anti HERR receptor trastuzumab can be used for ER/PR negative pts if HERR positive.
- it decreases rate of recurrence of breast CA

Inflammatory breast CA
Pt s/p breast CA tx with surgery, RT and chemotherapy p/w lymphedema of R arm, what is best management?
progressive resistance training
Tamoxifen
- decreases risk of new breast CA
- effective for tx metastatic breast CA
- works only if tumor ER & PR+
- effective in preventing cancer in high risk women
- tamoxifen has both estrogenic and anti estrogenic effects
Anti-estrogenic Effect:
- anti breast tumor effect , hence used in tx
- Menopausal symptoms (tx with venlafaxine)
Estrogenic effect:
- inc risk of endometrial CA x 3x–> screen by asking if has gyn symptoms
- inc bone density
- inc thromboembolic risk/PE***
If there is contraindication to tamoxifen, then ovarian ablation or suppression an be done.
