A) Small lump to breast ratio
b) Central breast tumor mass
c) Breast Tumor size less than 5 cm
d) Young age
Q2. Which is not true regarding BRCA mutations in breast cancer?
a) BRCA 1 tumors are high grade as compared to BRCA 2
b) BRCA 1 breast cancer are hormone receptor positive
c) BRCA 1 breast tumor are aneuploid
d) BRCA 1 breast cancer have an incraesed S phase fraction
Q3 ) Which of the following muscles do not form the posterior relation of breast?
a) Pectoralis major
b) Serratus Anterior
c) Rectus Abdominis
d) Lattismus Dorsi
Q4 Minimum number of lymph nodes to be dissected in Axillary sampling in brest conservation surgery is
Breast conservation involves resection of the primary breast cancer with atleast 2 mm margin of normal-appearing breast tissue, adjuvant radiation therapy, and assessment of axillary lymph node status.
Breast conservation surgery is contraindicated when
– the tumor is multicentric and multifocal
– the tumor is central, the advantages of preserving the breast are lost as nipple areola complex is sacrificed
– tumor is to breast ratio is large ie the form of breast is not preserved
– Patient is not a candidate for radiation exposure, eg pregnancy, previous history of radiation SLE etc
Age is no criteria.
BRCA1- associated breast tumors have a worse prognosis than BRCA2- associated breast cancers.
They are high grade, associated with negative ER- PR receptors, increased S phase fraction and aneuploid.
The deep or posterior surface of the breast rests on the fascia of the pectoralis major, serratus anterior, and external oblique abdominal muscles, and the upper extent of the rectus sheath.
Minimum number of lymphnodes to be removed in Axillary sampling is 4 and in Sentinel Lymph node biopsy is 2
In Breast conservation surgery the axilla can be dealt in three separate ways;
1. Sentinel Lymph Node Biopsy
2. Axillary sampling
3. Axillary Dissection
Sentinel Lymphnode biopsy axillary sampling is done for clinically node negative axilla.
