Q

What is the primary goal of cancer treatment

a. palliation
b. tumor reduction
c. improve quality of life
d. cure

20
Q

Two main types of cancer treatment

A
  1. local

2. systemic

21
Q

Examples of local cancer treatment

A

surgery

radiation

22
Q

Examples of systemic treatments

A

chemotherapy

biologics

23
Q

What do you call cancer growth curve pattern?

A

Gompertzian growth curve

24
Q

What is the most effective means of treating cancer?

25
Percentage of cancer patients cured by surgery today
40%
26
What do you call the type of resection where the tumor is completely excised with an adequate margin of normal tissue, touching the tumor as little as possible to preven vascular and lymphatic spread, and minimizing operative risk.
R0
27
lumpectomy with radiation therapy is as effective as modified radical mastectomy for breast cancer. T/F
T
28
Give 2 subsets of patients where surgery can be curative.
Resection of lung metastases from osteosarcoma hepatic lobectomy in colon cancer patients with fewer than five liver metastases restricted to one lobe and no extrahepatic metastases
29
Therapeutic radiation is delivered via focused beams of radiation generated at a distance and aimed at the tumor within the patient. a. teletherapy b. brachytherapy c. systemic therapy
A
30
Radioactive iodine is an example of a. teletherapy b. brachytherapy c. systemic therapy
C
31
Therapeutic radiation is delivered with encapsulated soruces of radiation implanted directly into or adjacent to tumor sites. a. teletherapy b. brachytherapy c. systemic therapy
B. brachytherapy
32
T/F radiation therapy is a local treatment therefore it's effects are all local
F; may have systemic effects including anorexia, nausea, vomiting
33
Which is the most radioresistant organ?
Bone
34
What are the most radiosensitive organs?
male testis, female ovary | bone marrow
35
T of chronic toxicities of radiation therapy a. Radiation of the head and neck region often causes hyperthyroidism b. It can cause blindness c. Salivary glands are not affected c. AOTA
B; a. it can cause thyroid failure c. salivary glands stop making saliva, may lead to dental caries and poor dentition
36
T/F MI can be a sequelae of radiation therapy
T; mediastinal irradiation
37
Use of focused microwave radiation to induce thermal injury within a volume of tissue
Radiofrequency ablation
38
Use of extreme cold to sterilize lesions in certain sites such as prostate, kidney when at a very early stage, eliminating the need for modalities with more side effects such as surgery or irradiation
Cryosurgery
39
Dose that conveys greater toxicity than would be acceptable in routine practice
Dose-limiting toxicity
40
What is the most immediate indicator of drug effect/response?
Tumor shrinkage
41
Decrease in tumor size by at least 50% is called a. incomplete response b. slight response c. partial response d. adequate response
C partial response
42
Definition of complete response
disappearance of all tumor
43
Definition of progression
increase in size of existing lesions by >25% from baseline or best response or development of new lesions
44
What do you call the dose regimen of chemotherapy that produce reversible acute side effects
conventional dose regimens
45
T/F High dose regimens have definite curative potential in defined clinical settings.
T
46
3 goals of palliative therapy using chemotherapy
1. improved symptom relief 2. progression-free survival 3. improved overall survival
