LESSON 1: Cell cycle
g1- increase in size
s- dna replicated
g2- cell enlarge and ready to divide
m phase- 2 hours
00:45
01:22
mitosis
4 stages, prophase, metaphase, anaphase, telophase
-chemo targets certain points in the process
apoptosis
programmed cell death
hematopoiesis
formation of blood cells & how cells differentiate
-myeloid: pre cells mature into RBCs, platelets and WBCs
-lymphoid: pre cells- mature into WBCS
Principles of Biotherapy: p51-95 immunology
-defense against foreign organisms, homeostasis (destroy aged cells), surveillance
immune responses
innate: primary line of defense, non specific, no memory
adaptive: secondary line of defence with specific memry
cytokines
-effect growth and differentiation of WBC
-interferons, tumor necrosis factors, growth factos and interleukins
-small protein molecules released by cells throughout body providing comunication between cells of the immune system
-regular antiboddy production and function of b cells
vaccines for cancer prevention
-hep B prevents hepatitis and hepatocellular carcinoma
-hpv vaccine
filgrastim aka neupogen
SC or IV to derease infection in patients with neutropenic fever associated with myelosuppressive anticancer treatments for nonmyeloid malignancies
tbo-filgramstim/ pegfilgrastim
reduce duration of neutroenia in patients with non myeloid malignancies
palifermin
IV to dec incidence of oral mucositis in patients with hem malignanies before BMT
00:02
01:22
sargramostim
aka leukine - patients with AML following chemo to shorten neutrophil recovery and reduce incidence of infection
IFN gamma
reduce frequency and severity o infections related to granulomatous disease
aldeleukin
treat renal cell carcinoma and metastatic melanoma
oprevelkin
prevent severe thrombocytopenia and refuce need for platelet transfusions in patients with nonmyeloid malig
plerixafor
with filgrastim to mobilize hematopoeitc stem cells for collection from peripheral blood of patients
sipuleucel
castrate resistant prostate cancer
rituximab
rituxan- treatment of relapsed or refractory low grade follicular b cell NHL_ first line traetment in combo with chemo in patients with response
-can treat severe rheumatoid arthritis
-can have severe reactions (hypotension, urticaria, angiodema, hypoxia, rigors, dyspnea, chills, fever, nausea, rash, renal tox)
-premed with tylenol and benadryl
-slow infusion to resolve some side effects, side effects reduce with each infusion
immune system
1st line: skin , ucous membrane, gut flora
second line: phagocytes:
3rd line antibodies, t and b cells
malignant tumor (cancer)
cell strcuture different from parent tissue, cell division uncontrolled, loosely adherent, invade neighboring tissue, establish blood vessels
Approaches to treatment
cure: prolonged absence of disease
control: no further growth
and palliation : comfort
neoadjuvant
therapy in the first step to shrink a tumor before the main treatment) surgery is given
-chemo, radiation, hormone therapy
adjuvant
therapy given afer primary treatment to lower risk of cancer coming back
-chemo, radiation, hormone, targeted and biologic therapy
myeloblation
obliteration of bone marrow with chemo in prep for blood stem cell or bone marrow trasnplant to destroy blood forming cells in the marrow and reduce tumor burden - destroy immune system so it cannot attack donated cells after transplant
nonmyeloblative
not as intense, chemo doses are not as intense
LESSON 2: Alkylating Agents
-cytoxan
-ifosframide
-bendamustine
platinum based chemo
consideration on age, kidney function, and concurrent use of radiation. both can cause nausea, vomiting, hearting loss, kidney function damage, electrlyte disturb. CBC chem panel and mag checked
-cisplatin: admin over longer period of time. nausea can last over a week
-carboplatin- risk with age >65, harder on kidney function. over shorter period of time, nausea within first 24 hours. neuro tox
cyclophasmide
hair loss 10-14 days post treatment
-can be given peripherally
-hemmorhagic cystitis - hydration is key, high dose may need bladder protection
-easier to give than iphosphamide
iphosphamide
neuro changes can occur- personality changes can occur, neuro checks before
central line only
-need a bladder protective agent 100% of the time
nitrosureas
cross blood brain barrier - can treat brain tumors. alkylating agents
-pulmonary monitoring
Lesson 3: Antimetabolites
-azacitidine
-capacitabine
-fluorouracil
-cytarabine
-decitabine
-methotrexate
inhibit DNA and RNA synthesis - can cause myelosuppression, GI toxicities, phospotsensitiivty, hand foot syndrome, vigorous I V hydration to prevent tumor lysis
5 fluorouracil (5 FU)
-IV oral topic and opthalmic formalation
-can cause hyperpigmentation, increased mucositis, photosensitivity, diarrhea
-capcytobine is the oral form - needs to be taken 2x day, hand foot syndrome can occur
-INR monitoring
methotrexate
antimetabolite, cell cycle specific to S phase
-cleared in kidneys - effects: hepatotox, renal tox, mucositis, nausea, myelosuppression, pneumonitis, photosensitivity, neurotoxicity, infertility
-yellow in color. renal function, hydrate 2-3L/ day, no alcohol use, sun exposrue, folic acid, avoid effusions
azacitidine
for treatment of myelodysplastic syndrome: group of cancers in which immature blood cells do not mature (SOB and fatigue are markers)
Lesson 4 A cautionary tale about routes
intrathecal chemo- injects chemo directly into the subarachnoid space so it reaches the CNA
-leukemia and lymphoma spreading to CNS since most chemo does not cross blood brain barrier
intrathecal chemo
ONLY methotrexate and cytarabine can be given IT
-IT hydrocorisone given at same time to reduce inflammation
vincristine
dilute in 20mL minibag and infuse over short time- IVP not reommended
vinblastine -dilute in 25-50 ns
Lesson 5 Antitumor Antibiotics
-anthracyclines: interfere with enzymes for DNA to replicate, work phases of the cell cycle
lifetime dose limites because they are cardiotoxic
-daunorubicin, doxorubicin, epirubicin, idarubicin
nonanthracycline: actinomycin, mitomycin, bleomycin
doxorubicin
vesicant
extravasation possible- must eval cardiac funciton, ongoing cardiac monitoring, hypersensitivity risk
-nausea/ vomiting, mucositis, diarrhea, myelosupression, hepatic impairment, secondary cancer
-cardiac: SOB< skipped beats, weight gain
-myelosuppress: oral temp daily, report >100.5
GI: nausea vomiting diarrhea, inspect mucosa
neuro: numbness/ tingling, burning
GU: change in color of urine
dexrazoxane
cardiac protectant given before
bleomycin
antitumor antibiotic - lifetime dose warning
-can cause hypersensitivity, skin reaction
-report SOB< skin issues, protect from sun
