EXAM #2: INTRODUCTION TO SURGICAL ONCOLOGY Flashcards
What website is the best resource for understanding the role of surgery in cancer therapy?
www.nccn.org
Specifically, the guidelines/ treatment recommendations.
What are the three major cancers that are NOT amenable to surgery?
Leukemia
Lymphoma
Small Cell Lung Cancer
What factor makes a cancer non-curable?
Distant metastasis
What is a negative margin in surgery?
The normal tissue that is removed with the surgical excision of a tumor, growth, or malignancy
What is the negative margin in breast cancer?
1mm
What is the negative margin in colon cancer?
5cm
What is “formal resection” in cancer?
- In colon resection; removal of the colon/cancerous tissue at the arterial root coming off the aorta to ensure removal of all the “curtains of lymph nodes”
This is in contrast to removal of the colon distal to the aorta for a colon resection to treat diverticulitis.
What is a major way to use surgery to diagnose a cancer?
Biopsy
How do you decide where to do a biopsy?
Go for the:
1) Most accessible
2) Least invasive
What surgical decision do you need to make about metastatic cancers?
Can removing the primary cancer + adjuvant chemotherapy cure, or do I need to take out the mets as well?
What is the procedure called that biopsy a breast cancer?
Stereotaxic needle biopsy
What is the procedure to determine the metastatic status of a breast cancer?
Sentinel lymph node biopsy
When are the two major cancers where surgery is a primary treatment?
Breast cancer
Colon cancer
When is surgery used as a secondary treatment?
Advanced stage:
- Esophageal
- Rectal
- Lung
- Breast
But NOT stage 4*
What is neoadjuvant therapy?
Chemotherapy/ radiation used prior to surgery to downstage a tumor
