Week 6- Oncology and Organ Transplant Flashcards
(112 cards)
Neoplasm is classified by what?
- cell type
- growth pattern
- anatomic location
- degree of dysplasia
- tissue of origin
- ability to spread or remain in the original location
What is the difference between a benign tumor and a malignant tumor?
- Benign tumor: differentiated cells that reproduce at a higher rate than normal and are often encapsulated, allowing expansion, but DO NOT spread to other tissues
- Malignant tumor: undifferentiated cells, are uncapsulated, and grow uncontrollably, invading normal tissues and causing destruction to surrounding tissues and organs; MAY spread to distant sites of the body
What is the difference between a primary and secondary tumor?
- Primary: original tumor in original locaton
- Secondary: metastases that have moved from the primary site
Terminology:
- _________ = “New growth” pertaining to an abnormal mass of tissue that is excessive, persistent, and unregulated by physiological stimuli.
- _______ = Common medical language for a neoplasm.
- ________ = A term for diseases in which abnormal cells divide without control and can invade nearby tissues. Malignant tumors are referred to as cancers.
- Neoplasm
- Tumor
- Cancer
Terminology:
- __________ = Variability of cell size and shape with an increased rate of cell division (mitosis).
- _________ = Replacement of one mature cell type by a different mature cell type, resulting from certain stimuli such as cigarette smoking.
- __________ = An increasednumberof cells resulting in an enlarged tissue mass. It may be a mechanism to compensate for increased demands, or it may be pathological when there is a hormonal imbalance.
- _________ = The extent to which a cell resembles mature morphology and function. A cell that is well differentiated is physiological and functions as intended. A poorly differentiated cell does not resemble a mature cell in both morphology and function.
- Dysplasia
- Metaplasia
- Hyperplasia
- Differentiation
What are the common S/Sx of Cancer?
- Unusual bleeding or discharge
- Unexplained weight loss (10lbs or more)
- Fever
- Fatigue
- Pain
- Persistent cough or hoarseness without cause
- Skin changes
Wat are the 2 main hallmarks of cancer?
- Unexplained weight loss
- Unexplained pain (no explained onset, wakes patient up)
What are some ways cancer is diagnosed?
- Medical imaging
- Blood tests for cancer markers
- Biopsy (definitive test to ID cancer type)
When it comes to cancer prevention, what are the 3 stages of disease prevention and what do each involve?
Primary
-Taking steps to prevent getting disease in the first place. (using sun block)
Secondary
-Involves using screening tools for early identification of cancer. (biopsy, stool guaiac, pap smear, sputum cytology, sigmoidoscopy, colonoscopy, etc…)
Tertiary
-Involves reducing symptoms and improving QOL in presence of disease.
Cancer ______ Describes the location and size of the primary site of the tumor, the extent of lymph node involvement, and the presence or absence of metastasis. This helps to determine treatment options, predict life expectancy, and determine prognosis for complete resolution
Staging
Cancer staging measures what 3 things?
TNM System
- T: extent (size and/or number) of tumor
- N: lymph node involvement
- M: presence/absence of metastasis
- The _____ system is commonly used to stage cancer.
- Generally the ______ the number, the more advanced.
- TNM
- higher
Cancer _______ reports the degree of dysplasia, or differentiation from the original cell type.
Grading
- Lower grade tumors: ______ differentiated cells that more closely resemble original cells
- Higher grade tumors: _____ differentiated (i.e., undifferentiated) cells that are less like original cells
- ______ grade tumors are more aggressive.
- Differentiation is a _____ thing.
- highly
- less
- higher
- good
With tumor grading, is G1 better or worse prognosis than G4?
Better
What are the 3 approaches to cancer treatment?
- Cure (adjuvent and neoadjuvent)
- Control (reduce new cancer growth)
- Palliation (cure not possible, make patient as comfortable as possible)
Difference between adjuvent therapy and neoadjuvent therapy
- Neoadjuvant therapies are delivered before the main treatment, to help reduce the size of a tumor or kill cancer cells that have spread.
- Adjuvant therapies are delivered after the primary treatment, to destroy remaining cancer cells
What are the 4 main cancer treatment options?
- Surgery
- Radiation
- Chemotherapy
- Biotherapy
Indications for Surgical Management:
- Removal of __________ lesions or of organs at high risk for cancer.
- Establishing a diagnosis by _______.
- Assisting in staging by sampling _____ _____.
- Definitive treatment by removing the ______ tumor.
- Reconstruction of a limb or organ with or without skin grafting.
- __________ care such as decompressive or bypass procedures.
- precancerous
- biopsy
- lymph nodes
- primary
- palliative
__________ primary objective is to eradicate tumor cells, either benign or malignant, while minimizing damage to healthy tissue.
Radiation
Indications for Radiation:
- Definitive treatment with the intent to cure.
- __________ treatment to improve chances of successful surgical resection.
- _________ treatment to improve local control of cancer growth after chemotherapy or surgery.
- __________ treatment to prevent growth of cancer in asymptomatic, yet high-risk areas for metastasis.
- Control to limit growth of existing cancer cells.
- Palliation to relieve pain, prevent fracture, and enhance mobility when cure is not possible.
- Neoadjuvant
- Adjuvant
- Prophylactic
What are the general side effects of radiation?
- skin reactions
- fatigue
- N/V/D
- weight loss
- myelosuppression
- Radiation can also case site-specific _________ such as limb edema, visual disturbances, pneumonitis, cystitis, and cardiomyopathy.
- ________ are often prescribed.
- toxicities
- antiemetics
With patients on radiation, we want to be careful of fragile _____.
skin
