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.
