Chapter 19 - Cancer Treatment Flashcards
Debulking procedure
To remove as much of the primary tumor mass as possible, even if the tumor is attached to a vital organ and cannot be completely removed.
Cauterization
Destruction of tissue by burning
Core needle biopsy
Insertion of a large-bore needle into tissue to extract (remove) a thin core of cells for microscopic examination.
Cyrosurgery
Use of subfreezing temperature to destroy tissue
En bloc resection
Tumor is removed along with a large area of surrounding tissue containing lymph nodes
Excisional biopsy
Removal of tumor and a margin of normal tissue
Exenteration
Wide resection involving removal of the tumor, its organs of origin, and all surrounding tissue in the body space.
Fine needle aspiration
Placement of a very thin needle inside the tumor mass and extracting cells for microscopic evaluation.
Fulguration
Destruction of tissue by electric sparks generated by a high-frequency current
Incisional biopsy
Piece of tumor is removed for examination to establish a diagnosis.
Brachytherapy
Radiotherapy (radiation therapy) that uses insertion of sealed containers into body cavities or radioactive seeds directly into the tumor.
Electron beams
Low-energy beams for treatment of skin or surface tumors.
External beam irradiation (teletherapy)
- Radiation therapy applied to a tumor from a distant source such as a linear accelerator.
- Beam is far from patient
Fields
Dimensions of the size of radiation area used to treat a tumor from a specific angle
Fractionation (!!!)
- Radiation doses split into intervals
2. Giving radiation in small, repeated doses rather than large doses.
