Sweatman Bladder Cancer and Ovarian Cancer Flashcards
(36 cards)
serum marker used to monitor the course (activity/progression) of ovarian cancer
CA 125
–> not very good diagnostically
unique mode of delivery of drug available for ovarian cancer with peritoneal seeding
IntraPeritoneal instillations
_decrease rate of buildup of the ascites
first options for ovarian cancer with/without seeding
High volume IP cisplatin
IP admin benefits
allows higher dose
- more frequent administration
- appears more effective
adjuvant therapy following cisplatin
STAGE 1 and 2
(confined to one or both ovaries/ spread to pelvis)
IV Carboplatin/cisplatin
include Cyclophosphamide
and or Doxorubicin
Adjuvant therapy stage 3-4
IV carboplatin/cisplatin with paclitaxel
targetted therapies for ovarian CA
none
Administration of IP dosing
- only for locally confined disease
- > 1-2 L retained for 2 hours then drained off
- pateint supine rotated from side to side to ensure adequate coverage
bladder cancer mutations
FGFR3
HRAS
Chromosome 9 (with a shit tone of shit)
highest risk factor for developing bladder cancer
long history of smoking
most common presenting symptom of bladder cancer
hematuria
*likely microscopic not gross)
main cell type incolved in 70% of bladder cancers
urothelial
70% are superficial on presentation
drugs most commonly used for intravesical instillation
Mitomycin
BCG
Thiotepa (less common)
progression of therapy in Bladder cancer pt.’s
- TURBC
- Intravessicular Mitomycin/ IVe BCG/other
- Chemo-radiation or systemic therapy
- cystectomy
activity of BCG requires
intact immune system
MOA for BCG (bacillus calmette Guerin)
Binds urothelium, activates APC’s, Induces host CTLs, NK’s, AK,’s, BAK’s
>for 6 weeks
>immune response detected wihtin hours and lassts for days
lipophillic small MW drug that can penetrate urothelial tissue
Thiotepa
most drugs in tx of bladder cancer are….
alkylating agents
forms DNA intrastrand corss links
Cisplatin and Carboplatin
Pro-Drug of alkylating moiety
Cyclophosphamide
intercolator, free radical generator and topo II inhibitor
Doxorubicin
Mono and Bi functional alkylating agents
mitomycin C
microtubule stabilizer inhibiting depolymerization
Paclitaxel
polyfunctional alkylator with loss of aziridine moeity
Thiotepa
remaininig moeity forms DNA cross links
