DEVELOPMENT
? Modified sweat gland ,derived from
ectoderm
? Development begins at 5th or 6th week of
intrauterine life
? Ectodermal thickening in the chest area -
mammary ridge/milk line/line of
Schultz
? Axil a to inguinal region
? In humans, these ridge disappears except
for a small portion over pectoral region
Formation of mammary gland
? Persisting part of the mammary ridge is first
converted into a mammary pit
? Secondary buds(15-20) grow down from floor of the
pit
? These buds divide & subdivide to form lobes
? Entire solid system is canalized later
Growth of mammary gland, at puberty caused by;
? Estrogen ? development of ductal system.
? Progesterone ? stimulates development of secretary
alveoli
q SITUATION:
Superficial fascia of pectoral region
q EXTENT OF BASE
?Vertically ? second to sixth rib in the
mid clavicular line
?Horizontally ? from lateral border of
sternum to anterior axillary line
?A thin layer of mammary tissue extends
from below the clavicle to 7th/8th rib and
from midline to edge of lattismus dorsi
posteriorly ( surgical imp.)
Divided into 4 quadrants :
? UPPER INNER
? UPPER OUTER
? LOWER INNER
? LOWER OUTER
AXILLARY TAIL OF SPENCE -
Passes through an opening in the deep fascia
(Foramen of Langer) and lies deep to deep
fascia
Upper outer quadrant is the most frequently affected quadrant by
carcinoma (60%) as the breast tissue is denser in this area
DEEP RELATIONS
? Deep pectoral fascia
? Muscles
i. Pectoralis major
i . Serratus anterior
i i.External oblique
? Anterior chest wall
STRUCTURE
? Skin
? Parenchyma
? Stroma
SKIN
q NIPPLE
? A conical projection in 4th
intercostal space
? Contains circular and
longitudinal muscles
? Pierced by 15-20 lactiferous
ducts
? Supplied by 4th intercostal
nerve
Infiltration of the lactiferous duct by tumor and subsequent fibrosis causes
RECENT RETRACTION OF THE NIPPLE
q AREOLA
? Skin surrounding the base
of the nipple
? Pigmented circular area
? Contains sebaceous, sweat
and accessory glands
MONTGOMERY'S TUBERCLES are sebaceous gland that are enlarged during pregnancy and lactation.
They produce oily secretions that lubricate nipple and areola and prevent it from cracking
PARENCHYMA
? Compound tubulo -alveolar gland
? 15-20 lobes - each has a cluster of
alveoli, and is drained by a lactiferous
duct
? Lobule- basic structural unit
? 10- 100 lobules ductules
lactiferous duct.
? Lactiferous sinus is the terminal
dilatation of the duct. It act as a
reservoir for milk or abnormal
discharge
? Terminal duct + lobule = Terminal Duct Lobular Unit
(TDLU)
Most cancers and benign lesions arise in the terminal duct either inside or just
proximal to the lobule.
STROMA
i. Fibrous stroma
1. Supporting framework of the
gland
2. Forms septa known as the
suspensory ligaments of Cooper
3. Anchor the skin to the pectoral
fascia
ii. Fatty stroma
1. Main bulk of the gland
2. Distributed all over the breast;
3. except beneath the areola &
nipple
Infiltration of the suspensory ligaments of Cooper by tumor cells
result in puckering or dimpling of the skin
BLOOD SUPPLY
q ARTERIAL SUPPLY
? Perforating branches of internal thoracic
Artery
? Branches of axil ary artery
i. Lateral thoracic artery
i . Superior thoracic artery
i i. Thoracoacromial artery
? Lateral branches of 2nd - 4th posterior
intercostal arteries
q VENOUS DRAINAGE
? Veins follow the arteries. First they converge
around the nipple to form an anastomotic
venous circle and then form 2 sets of veins
? Superficial veins - internal thoracic vein and
into the superficial veins of the lower part of
neck
? Deep veins - axillary and posterior intercostal
veins
Batson's vertebral venous plexus
? Network of valveless veins
? Through posterior intercostal
veins , venous drainage
communicates with
paravertebral venous plexus
Route for metastasis to the axial skeleton and Central nervous
system --- most common site : LUMBAR VERTEBRA
NERVE SUPPLY
? Anterior and lateral
cutaneous branches of
4th to 6th intercostal
nerves
? Sensory fibres to skin and
autonomic fibres to
smooth muscles and
blood vessels
Nerves do not control the secretion of milk (controlled by prolactin
hormone)
LYMPHATIC DRAINAGE
q LYMPHATIC VESSELS
? Superficial lymphatics ?
skin over the breast
? Deep lymphatics -
parenchyma, nipple and areola
? Subareolar plexus of Sappey -
a lymphatic plexus deep to areola
? The subareolar plexus of Sappey and outer quadrant of breast ->
pectoral -> central -> apical.
? Part of upper quadrant also directly drain to deltopectoral and
apical nodes.
? Inner quadrant -> internal mammary nodes and contralateral
breast.
? Lower inner quadrant ? traverses through the plexus in rectus
sheath ?communicate with subperitoneal plexus
q LYMPH NODES
? Axil ary nodes (85%)
? Internal mammary(Parasternal) nodes
? Intercostal nodes
? Some lymph also reaches
i. Supraclavicularnodes
i . Cephalic(deltopectoral) node
i i. Subdiaphragmatic lymph plexus
iv. Subperitoneal lymph plexus
Sentinel node is defined as the first lymph node draining the tumour-bearing
area of the breast
? Axil ary nodes :
Groups:
? Anterior(pectoral) ?
Main drainage
? Posterior (subscapular)
? Lateral(brachial)
? central
? Apical
? Interpectoral (Rotters)
LEVELS OF AXILLARY NODES
BERG 'S LEVEL
? Defined by their relationship to
pectoralis minor muscle
? Level 1 -Below and lateral
(anterior, lateral, posterior)
? Level 2 ? Behind
(central, inter pectoral)
? Level 3 - Above and medial
(apical)
AETIOLOGY
AND
PATHOLOGY
OF
CARCINOMA BREAST
Adila Rahim
ROLL NO: 3
AETIOLOGICAL FACTORS
1.Geographical
? commonly seen in Western world
2.Age
- rare < 20 years
then incidence with age
by 90 years ? 20 % women
are affected
3.Gender
females > males {< 0.5 %}
4. Genetic
BRCA 1
BRCA 2
p53
5.Family history
- more common in women with a family h/o breast & ovarian
cancer
- 3-5 times more risk if first degree relative has Ca.breast
- accounts for less than 5% of all breast cancer
6. Diet
low in phyto-oestrogens
7. Alcohol intake
increase the risk of developing Ca. breast
8. Endocrine
Protective factors :
- breast feeding
- first child at early age
- late menarche
- early menopause
Risk factors:
- nulliparous women
- obesity ( increased conversion
of steroids to estradiol in body
fat )
9. Oral contraceptives and HRT
The benefits of these treatment will far outweigh
the small putative risk; however ,long term
exposure to combined preparation of HRT does
significantly increase the risk.
10. Previous exposure to radiation
- Hodgkin's disease ? radiotherapy ? increased risk ? decade
after treatment
- higher risk if radiotherapy received during breast
development
PATHOLOGY
? Arises from the
epithelium of duct
system
? From the nipple end of
the major lactiferous
duct to the terminal
duct unit which is in the
breast lobule
PATHOGENESIS
? Genetic changes
? Hormonal influences
? Environmental variables
Genetic changes
? Over expression of HER2/NEU proto-oncogene
? Mutations of tumor suppressor genes like P53
? Gene array analysis of breast cancers has identified five
major subtypes:
1. luminal A : ER+ , Her-2-ve
2. luminal B : ER+ ,PR+ , Her-2+
3. Her-2 receptor positive: ER-ve
4. triple negative : ER-ve , PR -ve , Her-2 -ve
5. miscellaneous group
? Mutation in BRCA1 or BRCA2 genes
- responsible for one third
of hereditary breast Ca
- BRCA1 gene ?
at chromosome 17 (50-80% risk)
- BRCA2 gene ?
at chromosome 13
Both are classic tumour suppressor genes and cancer arises
only when both alleles are inactivated or defective
Hormonal influences
? Increased exposure to estrogen
? Stimulate production of growth factors ( TGF- ,PDGF
, FGF )
? Promote tumor development
SPREAD OF BREAST CANCER
By 3 means :
Local spread
Lymphatic metastasis
Spread by bloodstream
LOCAL SPREAD
Tumour increases in size
Invades other portions of breast
? It tends to involve skin
? May penetrate pectoral muscles and
even the chest wall if diagnosed late
LYMPHATIC METASTASIS
? Primarily to axillary and internal mammary lymph
nodes
? Tumours in the posterior one third of the breast drain
to the internal mammary nodes
SPREAD BY THE BLOODSTREAM
? By this route skeletal metastases occur
? Lumbar vertebrae, femur, thoracic vertebrae, rib and skull; deposits
are osteolytic
? Common sites : liver , lungs, brain , adrenal glands and ovary
TRANSCOELOMIC SPREAD
? Through mediastinal LN into peritoneal cavity.
? Cause secondaries in liver, peritoneum, ovary (Krukenberg tumours)
Note :
-- Present concept of Krukenberg ? haematogenous and lymphatic
modes.
-- Older concepts of transcoelomic spread no longer accepted.

CHEMOTHERAPY
Down staging
Chemo sensitivity assessment
Treat micro metastasis
SANDWICH THERAPY
? First anterior / neo-adjuvant
chemotherapy 3 - 4 cycles given.
? Followed by mastectomy - total or
modified radical mastectomy (MRM--
usually after 3 cycles of initial
chemotherapy).
? Further chemotherapy (remaining cycles).
Different regimens are:
? One day dose of all drugs of the regimen used as a standard at 3
weekly cycles for 6 cycles for stage II --CAF regime
? AC regime (Adriamycin and cyclophosphamide) with taxanes or
AC regime (4 cycles) followed by taxanes (4 cycles )are also used.
RESPONSE
? COMPLETE RESPONSE: no palpable tumour
? PARTIAL RESPONSE: > 50% decrease in size
? NON RESPONDERS: < 50% decrease in size or
increase in size up to 25%
? PROGRESSIVE: > 25%increase in size
? Nonresponders and progressive disease -
RT to breast, chest wall, axilla and
supraclavicular region; taxanes;
hormone therapy; surgery if operable.
? Responders - Total mastectomy/MRM.
After surgery remaining 2 or 3 cycles of
chemotherapy are completed.
Later hormone therapy should be given
for 5 years (tamoxifen 20 mg OD).

RADIOTHERAPY
INDICATIONS
? Breast conservation surgery (breast Irradiation after surgery)
In LABC -
? >4 positive Axillary lymph node.
? Level iii node , supraclavicular , internal mammary lymph node.
? Tumour size >5cm.
? Resection margin positive.
? Involvement of chest wall.
? Lymphovascular invasion.
? Inflammatory carcinoma.
MODES
EBRT(External Beam Radio Therapy)
Given over breast area, axilla, supraclavicular, internal mammary
area.
BRACHYTHERAPY
Radiation source is placed inside or close to the area requiring
treatment.
HORMONAL THERAPY
Administered only if ER/PR positive.
Gives prophylaxis against carcinoma of opposite breast.
IN PREMENOPAUSAL WOMEN
?
Tamoxifen
?
Ovarian ablation by surgery / by LHRH agonist / by radiation
?
Progestogens -- medroxyprogesterone 400 mg
?
Androgens -- fluoxymesterone
In postmenopausal women
?
Tamoxifen
?
Aromatase inhibitor like Letrozole 2.5 mg OD
?
Progestogens
?
Androgens
?
Medical adrenalectomy using Mitotane
TAMOXIFEN
It is a selective estrogen receptor modulator-SERM
Has anti estrogenic action in breast tissue & estrogenic action on other
tissues
Dose- 20 mg/day for a period of 5 years.
Adverse effects- Hot flushing,weight gain,bone pain , amenorrhoea,
increased risk of thromboembolism, vaginal dryness & atrophy, endometrial
carcinoma
LETROZOLE
In postmenopausal women estrogen is produced from androgens
secreted by adrenals
Inhibit aromatase enzyme that convert adrenal androgens to estrogen
Dose-2.5mg /day for a period of 5yrs
Adverse effects- vaginal dryness, hot flushes, vaginal bleeding,
osteoporosis, cardiovascular problems
TARGETED THERAPY -TRASTUZUMAB
Given in HER-2 / neu positive cases
Monoclonal antibody blocking HER-2/neu receptors on cell membrane.
Given as IV infusion.
Dose
Loading - 4mg/kg
Maintenance - 2mg/kg/week for 1year
Adverse effect- Cardiac side effects.
In LABC
? Radiotherapy is given pre operatively in case of non
responders to chemotherapy to reduce size and
down stage disease and post operatively if indicated.
? Hormone therapy should be started in al ER/PR +ve
patients after completion of chemo and carried on
for 5yrs.
? Targeted chemotherapy can be safely administrated
with neoadjuvant chemotherapy prior to
mastectomy.
TREATMENT OF
INFLAMMATORY CARCINOMA
Pre-operative :
? Chemotherapy
? External radiotherapy
Surgery whenever possible after that chemotherapy and
Tamoxifen is given.
+/- Breast reconstruction
BREAST RECONSTRUCTION
IMMEDIATE
In early stages of malignancy or in more advanced stages where the
response to neoadjuvant chemotherapy is good. Not in LABC.
Advantages
- preservation of maximum breast skin envelope
- psychological and economical benefit
Disadvantages
-radiation to prosthesis
-prolonged surgical procedure
DELAYED
Done 3-9 months after surgery
Indications
Locally advanced diseases
Post operative radiation is needed
Unfit for prolonged surgery
Advantages
Avoids prosthesis exposure to radiation
Avoids fibrosis and fat necrosis in TRAM flaps
Methods of Reconstructions
? Breast implants or expander.
? Flap reconstruction.
? Combined flap and implant or expander.
? Oncoplastic techniques.
SILICONE IMPLANTS
? most common type
? submuscular - placed below pectoralis major
? subcutaneous ? if RM done
FLAP RECONSTRUCTION
? LATISSMUS DORSI FLAP-
? 1st mucocutaneous flap to be
used.
? Based on THORACODORSAL
ARTERY
TRAM FLAP
? Most commonly used flap
? Skin and adipose tissue composition
are very similar between the breast
and the abdominal wall
? Based on superior epigastric artery
or free flap using microvascular
anastomoses of inferior epigastric to
thoracodorsal vessel.
COMBINED
? Prior tissue expansion using an expandable saline
prosthesis followed by replacement with silicon implant.
? LD/TRAM flap and silicon implant.
? In order to create some ptosis for the reconstructed
breast
NIPPLE-AREOLAR RECONSTRUCTION
? Done 2 ? 3 months after initial surgery under local anesthesia
? Nipple is created from local flaps of breast mount or prosthetic nipple
? Areola pigmentation (after 3wks of nipple creation) created using Ful
thickness skin graft from hyperpigmented non hairy area of body(groin) or
by medical tattooing.
