Cancer Pharmacotherapy EXAM 2 Flashcards
What do grading and staging tell about the progression of cancer?
Grade 1-3: well (slow growth) or poorly differentiated (fast growth)
Stage 1-4: TNM system (cancer-specific)
how far has it spread
Which drugs are in the following regimen?
R-CHOP
AC -> T
ESHAP
Surgical removement is ideal for which type of cancer cells
-small and at an early stage
solid tumors (no leukemia, or lymphoma bc it is in the blood)
Which types of cancer cells are ideal for radiation therapy?
-small tumor
-close to the surface of the body
example for the pancreas we would also have to penetrate the stomach (damage to the stomach, and less radiation gets to the pancreas due to absorption from the stomach)
Which equation is used for dosing in chemotherapy?
DuBois
Mosterllar equation
Know how to convert pt to kg, and inch to com
Convert 1 inch into cm and 1 kg into pounds?
1 inch = 2.54 cm
1 kg = 2.2 pounds
What is the dose for drug X based height and weight and BSA?
<5% difference range for the dose is OK
we don’t have to know the equation
What is the definition of definitve therapy
it is expected to cure the cancer with drug chemotherapy and/or radiation (not surgery)
Adjuvant therapy definition
after surgery (of primary tumor)
+
systemic chemotherapy to increase the chance of a cure;
-killing the remaining cancer cells which are in the log phase and susceptible to drug therapy
Neoadjuvant
adjunctive therapy (chemo) before surgery to improve the chance of cure
for example a cancer near to blood vessel that cant be cut out before we shrink the cancer with chemo
What is the definition of Palliative txt?
decrease the burden of disease, so they live longer (not trying to cure the cancer)
Which drugs have the most benefit after surgical removal as adjunctive therapy?
Immune checkpoint inhibitors (ICI) as adjuvant therapy
-Ipilimumab (Yervoy) - CTLA-4
-nivolumab (Opdivo) - PD-1 targeting
-pembrolizumab (Keytruda) - PD-1 targeting
immune cells (natural immune system?) works best when the number of cancer cells is lower
bc after removing the cells (surgery) the cells are in an early stage where they grow at a fast rate
Which phase of a trial do most findings of cancer drugs stem from?
Phase I
patients are treated with the highest possible dose to see what is the most tolerable dose
Cytarabin is given in which interval and why?
it runs 24h for 7 days to make sure it hits the cancer (leukemia) in the S-phase
