Study Notes
Patient Outcomes and Economic Impact
- Decreased patient complications can enhance overall satisfaction.
- Average cost of complications from surgical procedures is around $16,000.
- Compromised Intraoperative Radiation Therapy (IORT) leads to delays in adjuvant care.
Surgical Challenges
- Approximately 40,000 women undergo repeat operations annually due to positive margins after initial surgeries.
- Re-excisions double the risk of infection and create emotional stress for patients.
- Repeat operations contribute to a higher financial burden and worsened clinical outcomes.
- The surge in complications can increase healthcare costs by over $600 million annually.
MarginProbe® Technology
- MarginProbe® is a radiofrequency spectroscopy system that identifies positive margins in real time, allows surgeons to take immediate action, and reduces the need for subsequent re-excisions.
- The technology measures the bioelectric signature of the tissue to differentiate between malignant and benign cells.
Breast Cancer Biology
- Hormone receptor status significantly affects treatment pathways. Approximately 80% of breast cancers are estrogen receptor-positive (ER+) and 65% are progesterone receptor-positive (PR+), making them more amenable to hormone therapies.
- Breast cancers can be classified based on the presence of HER2 protein; overexpression correlates with faster growth and a higher likelihood of benefiting from targeted therapies.
Cancer Staging Approaches
- The AJCC TNM classification system is used to stage breast cancer, focusing on Tumor size (T), Node involvement (N), and Metastasis (M).
- High HER2 levels indicate more aggressive cancer behavior and necessitate targeted treatments.
Tumor Grading
- Tumor grade assesses how quickly cancer is likely to grow based on cellular characteristics, resulting in grades from low (Grade 1) to high (Grade 3).
- Factors for grading include tubule formation, nuclear pleomorphism, and mitotic count of tumor cells.
Triple-Negative Breast Cancer
- Characterized by the absence of ER, PR, and HER2 receptors, thus exhibiting resistance to hormonal and targeted therapies.
- This subtype accounts for 10-20% of breast cancer cases and has a poorer prognosis but responds well to neoadjuvant chemotherapy.
- A substantial proportion of patients with BRCA mutations present with triple-negative breast cancer.
Future Directions in Oncology
- MarginProbe® and similar technologies are anticipated to have broader applications in oncology, particularly in biopsy and targeted treatment protocols.
- Understanding biomarkers (ER, PR, HER2) is crucial as they dictate informed treatment decisions, enhancing personalized medicine approaches.
