LOCALLY ADVANCED BREAST CANCER
DEFINITION: Women with stage IIIA and IIIB
breast cancer have advanced local-regional breast
cancer but have no clinically detected distant
metastases.
• LABC includes stage III A and III B of TNM staging
– AJCC 2010
TNM STAGING OF LABC
T N M
STAGE III A T3 N1 M0
T0-3 N2 M0
STAGE III B ANY T4 N0-2 M0
STAGE III C ANY T N3 M0
CLINICAL PRESENTATION
• Skin edema- peau’d orange
• Satellite skin nodules
• Skin ulceration
• Tumor fixation to the chest wall
• Fixed axillary nodes
• Infraclavicular, internal mammary, and
supraclavicular adenopathy
• TRIPLE ASSESSMENT.
• CORE NEEDLE BIOPSY - histology and receptor status
studies
• MAMMOGRAPHY to the contralateral breast
• METASTATIC WORK UP -
– Chest X Ray
– USG abdomen pelvis,
– Liver function tests
– CT chest,
– Skeletal survey by Bone scan or X-rays
– CT brain - only if symptoms suggestive.
• ROUTINE EVALUATION
INVESTIGATIONS
Why no FNAC?
• Histological type, grade and receptor status is
must for all LABC
• Receptor status helps in selecting
chemotherapeutic agents
• Triple negative tumors – Adriamycin based
chemotherapy
• Her 2 positive tumors- Herceptin can be added
• Tumor may completely disappear after anterior
or neo adjuvant chemotherapy
SKELETAL SURVEY
• A routine X-ray will pick
up metastatic lesion
only when 60% of the
bone is demineralized.
• Bone scanning will pick
up metastases even
<30% demineralization
in about 20–30% of
cases of stage III breast
cancer
MANAGEMENT OF LABC
Options available:
I. Chemotherapy
II. Surgery
III. Radiotherapy
IV. Hormone Therapy
Multi-pronged approach adopted
Single approach ineffectual

OPERABLE SUBSETS OF LABC
• Mobile axillary node

CHEMOTHERAPYAPPROACH
Types;
A. Neoadjuvant Chemotherapy (Anterior or upfront )
 Administration of Cytotoxics in large operable tumours
before surgery
 Reduce loco-regional tumour burden – downstage
 Amenable to surgical resection after 3 doses
B. Adjuvant Chemotherapy
 Administration of Cytotoxics after surgery
 Eliminate clinically undetectable distant spread
C. Palliative Chemotherapy
 Advanced Ca Breast
 Metastatic Ca Breast

– Or 6mg/kg i.v every 21 days
– For one year
RESPONSE TO CHEMOTHERAPY
• Complete responders – 100%
• Partial responders – 50-99%
• Poor/non responders- <50% decrease or upto
25 % increase
• Progressive disease - >25% increase or
appearance of new lesions
Locally Advanced Breast Cancer
Duration of neoadjuvant chemotherapy
– Optimal duration of treatment is not known.
– Rule of thumb: “treat until maximal response.”
– May require from 2-8 treatments, depending on
rapidity of response.
– Patients should be assessed by multidisciplinary team
after every 2 cycles of chemotherapy to determine
optimal timing of surgery.

breast
 Useful in Metastatic Carcinoma
 Reduces recurrence – improves quality of life and
longevity
39
LOCALLY ADVANCED BREAST CANCER
Hormonal Management, continued:LIMITIONS
• Rate of pathologic complete response is greatly
diminished.
• Rate of breast-conserving treatment is greatly
diminished.
• Response to treatment is much slower, e.g. 3-9
months.

– Surgery (if downstaged) + Axillary clearance
– Five years survival 25-30%
45
Inflammatory Vs Noninflammatory
Breast Cancer
Inflammatory Noninflammatory
Dermal lymph vessel invasion is present
with or without inlflammatory changes
Inflammatory changes are present without
dermal invasion
Cancer is not not sharply delineated Cancer is better delineated
Erythema and Edema frequently involve
>33% of the skin over breast
Erythema is confined to the lesion , and
Edema is less extensive
Lymph node involvement is >75% of cases Lymph nodes are involved in approximately
50% of the cases
Distant metastases are present in 25% of
the cases
Distant metastases are less common at
presentation
Distant metastases are more common at
initial presentation
BCS in LABC
• Following neoadjuvant therapy , down staging
of breast cancer allow for breast conservation
sugery.
• SELECTION CRETIRIA
 Complete resolution of skin edema
 Residual tumour diameter <5cm
 Absence of known multicentric
disease/extensive lymphatic invasion
Follow-up
• Clinical examination in detail @ regular
intervals
• Yearly/2-yearly Mammography of the treated
and contralateral breast is a must
• Bone-scan, CT Chest/abdomen, tumour
markers are done only if there is clinical
suspicion. Not a regular routine follow-up at
present
