Lecture 3 Oncology Flashcards
Adenocarcinoma is ____ tissue
Glandular
Sarcomas Effect
Connective tissue, bones and muscle
Staging of cancer is
Finding out how much there is and where it is
Grading of cancer is
The degree of aggressiveness
The four cancers that are not classified by TNM staging
Bone, spinal cord , blood and bone marrow
T stands for the
Extent or size of primary tumor
Tx means
Cannot be evaluated
The T range is from
t0-T 4 , 4 is largest
N stands for
Extent of spread to the lymph nodes
Nx means
Cannot be evaluated
N0 means
No regional nodes involved
N1-N3 means
Increases with greater number
The more nodes you take out there is ___ risk of lymph edema
Increased
M stands for
Presence of distant metastasis
Mx means
Cannot be evaluated
M0 means
No metastasis
M1 means
Metastasis is present
Stage 0
No metastasis, carcinoma in situ
Stage 1
Localized to organ or origin , extends within the organ
Stage 2
Limited local extension and/or regional lymph node
Stage 3
Greater spread in the region around the organ, increased probability of metastatic spread
Stage 4
Distant spread beyond the local site
G1
Well differentiated, low grade, least aggressive
G2
Moderately differentiated, intermediate grade
G3
Poorly differentiated, high grade
G4
Undifferentiated, high grade
Myelosuppression
Decrease in number of blood cells that can lead to low blood levels
Pancytopenia
Low levels of platelets, red and white blood cells
Thrombocytopenia
Low platelets
Neutropenia
Decreased neutrophils which leads to low white blood cell count
Neutropenia is associated with high risk for
Infection
Palliative
Provides of with relief of symptoms, pain and stress of serious illness
Adjuvant
Additional cancer treatment after the primary treatment to prevent re occurance
Debulking
Procedure whereby a surgically incurable malignant neoplasm is partially removed without curative intent in order to make subsequent therapy with drugs, radiation or other adjunctive measures more effective and thereby improve the length of survival
Low red blood cells can be expected in patients undergoing
Chemo
Neutropenia value
1,500/mm^3
Thrombocytopenia levels
50,000/mm^3
Cancer cells will keep the ____ characteristics as the site of origin
Same
Most common sites of bone metastasis
Bone, liver and lungs
Port a cath is a
Catheder surgically inserted into the vena cava or subclavian artery to administer chemo drugs
Best way to overcome symptoms is to
Be active
Hospice means patient has less than _ months to live
6
Cardiovascular toxicity from chemo causes
L ventricular dysfunction leading to decreased CO
Carcinomas are
Fast growing
Pulmonary toxicity is
Decreased lung capacity and diffusion capacity
