Approximately 20 to 25% of women present
with locally advanced cancer.
Inflammatory breast cancer represents 1 to 3%
of diagnosed breast cancers.
Long-term survival can be obtained in
approximately 50 % of women with locally
advanced breast cancer who are treated with a
multimodality approach.
5-year relative survival rates for patients presenting
with stage IIIA ⇒ 52 % and stage IIIB ⇒ 48 %
3. locally advanced breast cancer includes patients
with stage III disease, this comprises:
Advanced primary tumors:
•
•
•
(T3): Tumors > 5 cm in greatest dimension.
(T4): Direct extension to the chest wall and/or to the skin.
Inflammatory breast cancer.
Advanced regional lymph nodes:
•
(N2): Ipsilateral level I, II axillary lymph nodes that are clinically fixed
or matted or clinically detected internal mammary lymph nodes in the
absence of axillary lymph node metastases.
•
(N3): Ipsilateral infraclavicular (level III axillary) lymph nodes,
ipsilateral internal mammary lymph node(s) with axillary lymph nodes, or
ipsilateral supraclavicular lymph nodes.
4. work up updates
NCCN 2013 guidelines
Breast MRI, bone scan. (category 2B).
Abdominal imaging with diagnostic CT (without
pelvic CT) or MRI (category 2A) are optional unless
directed symptoms or other abnormal study results.
PET/CT scan is also included as an optional
additional study (category 2B), The consensus of the
Panel is that FDG PET/CT is most helpful in
situations where standard imaging results are equivocal
or suspicious.

Compared to adjuvant chemotherapy, the clinical
trials have demonstrated no difference in OS or DFS.

clinical trials and perspectives. Cancer Lett 2007; 248:175.
12. 3 Main Results:
• At 16 years update ⇒ no diffr. in OS & DFS.
• The rate of ipsilateral breast cancer recurrence
was slightly higher in the neoadjuvant group
(10.7 versus 7.6 %), especially among younger
patients (age ≤50 years).
• Statistically significant correlation between
primary tumor response and outcome.
