Emerging Technology & Treatment Flashcards
Concept of the sentinel node
If the sentinel node is clear then the rest of the node basin is clear
Concept of the sentinel node
If the sentinel node is clear then the rest of the node basin is clear
Biopsy device uses a rotating cutting knife and vacuum-assisted tissue retrieval. (Stereotactic biopsy gun)
Mammotome
Tsukuba scoring system applies to what imaging technique for breast ultrasound?
Strain Elastography
DCIS is a stage ____ cancer.
0
Cytology analysis
Is less invasive retrieval
Smear of cells with less accuracy than histology
Retrieval is FNA
When performing an ultrasound guided biopsy the needle should be positioned
Parallel to the chest wall and parallel to the skin
CAD
Computer aided detection with manmography
ER-/PR-/HER- breast cancer is
Triple negative
What is the sentinel node?
The first node to drain lymph from a specific region of the breast
The most significant benefit of tomosynthesis or 3D mammography is
Ability to see slices of breast tissue without tissue overlap
Somography documentation during biopsy should include
Visualization of biopsy needle within the mass
Guidance of biopsy needle to the mass
Thorough pre-scan for localization of the mass
Histology analysis
Core biopsy
Can see cellular anatomy
More accurate diagnosis than cytology
An E/B ratio of less than 1 implies
The diameter measurement of the breast lesion on B-mode exceeds the diameter measurement of the color on elastography
For surgical lymph node dissection, the axillary lymph nodes are divided into 3 levels depending on their anatomic relationship with
Pectoralis minor muscle
Due to the retrieval method, which of the following biopsy techniques offer cytologic findings only?
FNA
One method of staging breast cancer upon diagnosis is by using
TNM classification
One method of staging breast cancer upon diagnosis is by using
TNM classification
Stage 4 breast cancer means
Breast cancer with distant metastasis
FNA
Fine needle aspiration
When performing an US guided biopsy the needle should be positioned
Along the long axis of the transducer
T2 N1 M0 breast cancer is
Medium sized tumor, with lymph nodes, no metastasis
The best position of a localization wire for open surgical biopsy is
Within the tumor
The breast is immobilized with which form of biopsy technique?
Stereotactic mammography
TRAM
Transverse rectus abdominis myocutaneous muscle
If the sentinel node is free from cancer, what other procedure may be alleviated?
ALND
TRAM flap surgery is a common procedure for
Reconstruction of the breast following mastectomy
Surgical removal of the breast, axillary lymph nodes, and pectoral fascia?
Modified radical mastectomy
HER2 is a protein common in 25% of breast cancers. What does HER2 stand for?
Human epidermal growth factor receptor 2
Positive response to chemotherapy treatment for a breast cancer patient on ultrasound would be the appearance of
Decrease in tumor size and decrease blood flow on Doppler
Optimal needle placement during US guided biopsy is
Needle within the lesion
Tamoxifen is a popular treatment for breast cancer that is also linked to
Endometrial hyperplasia
Breast reconstruction surgeries
DIEP flap
TRAM flap
gluteal artery flap
T in TNM stands for
Tumor size
M stands for in TNM
Metastasis
In relation to the face of the transducer, which is the optimal plane to visualize the biopsy needle
