Study Notes
Breast Cancer and MarginProbe Technology
- MarginProbe is a technology that helps detect cancer cells during breast cancer surgery.
- Breast cancer can be categorized into different stages, including normal ductal hyperplasia, atypical ductal hyperplasia (ADH), ductal carcinoma in situ (DCIS), and invasive ductal cancer (IDC).
Breast Cancer Diagnosis and Treatment
- Breast cancer diagnosis involves imaging tools such as mammograms, ultrasound, and low-dose X-rays.
- Mammograms can be limited in detecting tumors in dense breasts, which is a common issue in 40% of the population.
- Biopsies can be used to diagnose cancer, including fine needle aspiration, core needle biopsy, and surgical biopsy.
Breast Cancer Staging
- The American Joint Committee on Cancer (AJCC) uses the TNM system to stage breast cancer, which takes into account the tumor size, lymph node involvement, and metastasis.
- Additional factors such as estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) status are also considered.
- The staging system has been updated to include genomic profiles, such as Oncotype and Mammaprint.
Biomarkers and Treatment
- Biomarkers such as ER, PR, and HER2 can affect treatment choices.
- Hormone receptor status (ER/PR) can be used to guide hormone therapy.
- HER2 status can be used to guide targeted therapy.
- Triple-negative breast cancer is a subtype that lacks ER, PR, and HER2 expression, and is often more aggressive and has a poorer prognosis.
Tumor Grade and Staging
- Tumor grade is a measure of how quickly a breast tumor is likely to grow and spread.
- A score of 1-3 is used to describe the tumor grade, with 3 being the most aggressive.
- The staging system combines the TNM system with the tumor grade and biomarkers to provide a more accurate prognosis.
Lumpectomy and Breast Conserving Surgery
- Lumpectomy, also known as breast-conserving surgery, is a surgical procedure that removes the tumor and a small amount of surrounding tissue.
- The goal of lumpectomy is to achieve negative margins, which reduces the risk of local recurrence.
- A margin of 2mm or more is considered negative, but clinical judgment should be used for margins between 2mm and 1mm.
Hemostasis
- Hemostasis is the process of stopping bleeding during surgery.
- Hemostatic agents, such as collagen, thrombin, and chondroitin sulfate, can be used to aid in hemostasis.
- The SPOT GRADE scale is a validated system for measuring bleeding severity during surgery.
