Chapter 19: Cancer Medicine (Oncology): Laboratory Tests and Clinical Procedures Flashcards
cytogenic analysis
Chromosomes of normal or tumor cells are examined for breaks, translocations, or deletions of DNA
immunohistochemistry
Localization of antigens or proteins in tissues causing labeled (coloured or fluorescent) antibodies
protein marker tests
Measure the level of proteins in the blood or on the surface of tumor cells
bone marrow biopsy
Aspiration of bone marrow tissue and examination under a microscope for evidence of malignant cells
bone marrow transplantation
stem cell transplantation
Bone marrow or stem cells are infused intravenously into a patient
autologous marrow transplantation
Marrow previously obtained from the patient and stored is reinfused when needed
allogeneic marrow transplantation
Marrow is obtained from a living donor other than the recipient
peripheral blood stem cell transplantation
Immature blood cells called stem cells are selected and harvested from the blood of a patient instead of from the bone marrow
core needle biopsy
Insertion of a large-bore needle into tissue to remove a core of cells for microscopic examination
exfoliative cytology
Cells are scraped from the region of suspected disease and examined under a microscope
fiberoptic colonscopy
Visual examination of the colon using a fiberoptic instrument
laparoscopy
Visual examination of the abdominal cavity using small incisions and a laparoscope
mammography
X-ray examination of the breast to detect breast tissue
PET-CT scan
Diagnostic procedure combining CT (computed tomography) and PET (positron emission tomography)
radionuclide scans
Radioactive substances (radionuclides) are injected intravenously, and scans (images) of organs are obtained
