Cancer Care Flashcards
Cyclophosphamide
- Class
- MoA
- Adverse effects
- Alkylating agents
- Causes cross-linking in DNA
- Haemorrhagic cystitis, myelosuppression, transitional cell carcinoma
Bleomycin
- Class
- MoA
- Adverse effects
- Cytotoxic antibiotics
- Degrades preformed DNA
- Lung fibrosis
Anthracyclines (e.g doxorubicin)
- Class
- MoA
- Adverse effects
Cytotoxic antibiotics
Stabilizes DNA-topoisomerase II complex inhibits DNA & RNA synthesis
Cardiomyopathy
Methotrexate
- Class
- MoA
- Adverse effects
- Antimetabolites
- Inhibits dihydrofolate reductase and thymidylate synthesis
- Myelosuppression, mucositis, liver fibrosis, lung fibrosis
Fluorouracil (5-FU)
- Class
- MoA
- Adverse effects
- Antimetabolites
- Pyrimidine analogue inducing cell cycle arrest and apoptosis by blocking thymidylate synthase (works during S phase)
- Myelosuppression, mucositis, dermatitis
6-mercaptopurine
- Class
- MoA
- Adverse effects
- Antimetabolites
- Purine analogue that is activated by HGPRTase, decreasing purine synthesis
- Myelosuppression
Cytarabine
- Class
- MoA
- Adverse effects
- Antimetabolites
- Pyrimidine antagonist. Interferes with DNA synthesis specifically at the S-phase of the cell cycle and inhibits DNA polymerase
- Myelosuppression, ataxia
Vincristine, vinblastine
- Class
- MoA
- Adverse effects
- Acts on microtubules
- Inhibits formation of microtubules
- Vincristine: Peripheral neuropathy (reversible) , paralytic ileus
- Vinblastine: myelosuppression
Docetaxel
- Class
- MoA
- Adverse effects
- Acts on microtubules
- Prevents microtubule depolymerisation & disassembly, decreasing free tubulin
- Neutropaenia
Irinotecan
- Class
- MoA
- Adverse effects
- Topoisomerase Inhibitors
- Inhibits topoisomerase I which prevents relaxation of supercoiled DNA
- Myelosuppression
Cisplatin
- Class
- MoA
- Adverse effects
- Other cytotoxic drugs
- Causes cross-linking in DNA
- Ototoxicity, peripheral neuropathy, hypomagnesaemia
Hydroxyurea (hydroxycarbamide)
- Class
- MoA
- Adverse effects
- Other cytotoxic drugs
- Inhibits ribonucleotide reductase, decreasing DNA synthesis
- Myelosuppression
Chronic myeloid leukaemia - Philadelphia chromosome
Translocation between long arm of chromosome 9 and 22
t(9:22)(q34; q11).
Results in BCR-ABL gene, a fusion protein that has tyrosine kinase activity in excess of normal
Chronic myeloid leukaemia first line
Imatinib (tyrosine kinase inhibitor)
coeliac disease blood film findings
Target cells and Howell-Jolly bodies → hyposplenism
HJB = remnants of nuclear DNA inside RBC)
