Etiology
Epidemiology
- most common cause of cancer-related death in women age 35-54
- 10-12% of women will develop breast cancer
- 3.5% will die of the disease
- incidence is 20% higher in whites
- mortality rates are 15% higher in blacks
Pathology
- in general, patients with estrogen receptor positive tumors have a better prognosis
- infiltrating ductal carcinoma is the most common histological type
- lobular type is more frequently multifocal & bilateral
- ductal carcinoma in situ is non-invasive ( basement membrane is preserved)
- sites of metastases (of those that metastasize)
- lymph nodes (60-80%)
- liver (40-60%)
- lung (66%)
- bone (62%)
- brain (23%);
- changes in ER/ PR status in 40% of metastases [45]
- changes in HER2 status in 8% of metastases [45]
Genetics
-
- 10% incidence at age 47 within 2 years
- overexpression in 15-25% of cases
- overexpression predicts more aggressive disease
- BRMS1 is a breast carcinoma metastasis suppressor gene that maps to 11q13, a hotspot in breast cancer progression
- fascin marks & mediates breast cancer metastasis to lungs
- Li-Fraumeni syndrome
- 70% of cases are sporadic
- 17q23 region is commonly amplified
- methylation-mediated silencing may affect genes & proteins that act as positive mediators of cell death including: PYCARD
- other implicated genes

Clinical-manifestations
- solitary or dominant breast mass
- breast thickening or asymmetry
- skin edema and thickening
- lobular breast carcinoma may be felt as a fullness rather than as a distinct mass
- nipple inversion
- unilateral bloody discharge
- axillary or supraclavicular mass
Laboratory
- routine blood tests not indicated in the absence of specific symptoms
- core-needle biopsy
- may be stereotactically guided by mammography
- open excisional biopsy
- fine needle aspiration ( FNA) not recommended [4]
- for diagnosed breast cancer
- estrogen receptor & prostesterone receptor
- HER2/neu
- FISH or PCR/ southern blot/ northern blot/ISH for HER2/neu if histopathology confirms invasive breast cancer
- nipple discharge fluid for cytology [4]
- not routine
- USPSTF recommends against BRCA1 & BRCA2 genetic testing in women without family history of breast cancer [32]
- DNA microarray analysis
- prognosis for developing metastasis in axillary node-negative breast cancer [13]
- bone marrow aspirate for micrometastasis [33]
- autoantibodies: KIAA1671
- prognostic markers: EBAG9
Radiology
-
- 10% of breast carcinoma is negative on mammography
- sensitivity of mammography may be much less in high-risk women [27]
- core or excisional biopsy if mammography is negative, but lump or mass is present
- mammography screening leads to 15-25% overdiagnosis of invasive breast cancer [57]
- ultrasonography as indicated
- MRI in high-risk women [27,31]
- bone scan not routinely indicated
- negative imaging does not rule out breast cancer [4]
Complications
-
- 30-50% of all long-bone pathologic fractures
- most commonly occurs in proximal femur
- persistent cognitive impairment > 20 years after adjuvant chemotherapy [56]
- disease interaction(s) of cancer with Alzheimer's disease
Differential-diagnosis
-
- most common during breast involution which begins at age 35 & continues through menopause
- ultrasound & core or excisional biopsy are useful for distinguishing cysts from solid tumors
- generally secondary to gram positive organisms
- associated signs of infection may be present
- response to antibiotics distinguishes from breast cancer
- 80% of non- palpable suspicious breast lesions detected by mammography will be found benign on biopsy
Management
- staging/prognosis
- lymph node involvement & tumor size are most important prognostic indicators
- sentinel lymph node biopsy has replaced axillary lymph node dissection for staging in clinically lymph node negative women with early-stage breast cancer
- the majority of woman with positive axillary node(s) will have recurrence, thus are candidates for adjuvant therapy to surgery
- 25-30% of axillary node negative women will experience disease recurrence
- 10% of women with tumors < 1 cm will have recurrence
- receptor status, tumor grade, DNA index & S-phase fraction also affect likelihood of recurrence
- gene expression profiling is gaining acceptance
- treatment modalities
- surgery [47]
- breast-conserving therapy ( lumpectomy + axillary dissection combined with radiation)
- standard of care for all patients with early disease [14]
- modified radical mastectomy
- removal of breast
- axillary dissection
- preservation of pectoral muscle
- with or without breast reconstruction
- mastectomy is not indicated for patients with metastatic breast cancer unless required for local cancer control [4]
- prophylactic mastectomy is NOT completely protective against development of breast cancer
- axillary node dissection
- indication: positive sentinel node biopsy ? [54]
- not indicated for carcinoma in-situ or metastatic breast cancer
- does not affect overall survival or disease-free survival [54]
- chronic pain common after breast cancer surgery; associated factors include younger age, adjuvant radiation therapy, & more-extensive axillary surgery [48]
- used with breast-conserving therapy
- 4500-5000 cGy ( mega voltage radiation)
- justified even for tumors < 1 cm in size [15]
- axillary irradiation after axillary dissection is NOT indicated; results in unacceptable lymphedema
- reduces risk of recurrence after lumpectomy even in patients who receive adjuvant tamoxifen
- reduces risk of recurrence after breast conserving surgery [55]
- longer interval from breast conserving surgery to radiotherapy increases incidence of local recurrence in elderly women [50]
- indicated after mastectomy if:
- close surgical margins
- dermal invasion
- 4 or more positive nodes
- pharmaceutical agents ( chemotherapy)
- hormonal ( tamoxifen or aromatase inhibitor) or chemotherapy not recommended for node-negative tumors < 0.5 cm in size
- tamoxifen recommended for
- node-positive women > 50 years of age -> both estrogen receptor positive & negative patients allegedly receive benefit
- estrogen receptor positive tumors > 2 cm, or 1-2 cm with other poor prognostic indicators
- node-negative, receptor positive women > 60 years of age [25]
- premenopausal women with estrogen receptor positive breast cancer; 5 years of therapy [4]
- aromatase inhibitors may be superior to tamoxifen in post-menopausal women [4,19,52]
-
- anastrozole ( Arimidex) [6,10,28,41]
- letrozole ( Femara) [35]
- exemestatine ( Aromasin)
- combination chemotherapy, adjunct to radiation, surgery
- not indicated in ER/ PR receptor positive patients with either bone or asymptomatic visceral metastases [4]
- indicated for most other patients with invasive breast cancer [4]
- see chemotherapy for breast cancer
- addition of trastuzumab to chemotherapy
- reduces risk of recurrence, 2nd primary cancer, & mortality
- may benefit HER2/neu-positive (node-positive) patients [4]
- cardiotoxicity of chemotherapy [36]
- endocrine therapy [7,16]
- surgical: ovariectomy, adrenalectomy
- pharmaceutical agents:
- metastatic breast cancer & relapse
-
- paclitaxel plus bevacizumab [44]
- trastuzumab plus docetaxel (HER2 +)
- pertuzumab, trastuzumab & docetaxel (HER2 +)
- high dose chemotherapy with autologous bone marrow or stem cell transplantation [3]; not recommended [4]
- bisphosphonates &/or radiation therapy for painful lytic bone lesions [4]
- mean survival of recurrent breast cancer is 2.5 years from the diagnosis of recurrence
- support groups may be helpful for some patients [12]
- prognosis
- prognosis better with estrogen receptor positive tumors
- prognosis worse with increasing age
- prognosis worse after recent pregnancy [20]
- prognosis improved by exercise [30], as little as 3-5 hours walking weekly at 2-3 miles/hour
- comorbidities partly explains racial differences in survival [34]
- see staging of breast cancer (5 year survival by initial staging)
- 70% of symptomatic recurrences occur between scheduled exams [37]
- prognosis for multicentric disease similar to unicentric disease [38]
- invasive breast cancers may regress [43]
- local tumor recurrence correlates with risk of distant metastases [51]
- prognosis is improved with a multidisciplinary team approach [59], but cost-effectiveness is unknown
- follow-up of women with treated early-stage breast cancer (< 5 cm tumor, < 4 positive nodes) can be tranferred to primary care after 1 year with same outcome [37]
- follow-up of women who survive breast cancer; see breast cancer survival
- prevention of breast cancer
- * osteoporosis therapy in estrogen-deprived patient
