Lymphomas, Sarcomas, Carcinomas, Small cell lung cancer, Ovarian cancer, Germ cell tumors, Metastatic Testicular Tumors, Metastatic Ovarian Tumors, Advanced Bladder Cancer
Adult Dose
Metastatic Testicular Tumors
Usual dose in combination with other approved chemotherapeutic agents is 20 mg/m²/day IV for 5 days/cycle
Pretreatment hydration: 1-2 L fluid infused for 8-12 hr before dose
May use concomitant amifostine to decrease nephrotoxicity
Do not repeat course until SCr <1.5 mg/dL [<133 micromoles/L] or BUN <25 mg/dL [<8.93 mmol/L] or WBC >4000/mm³ AND platelets >100 k/mm³
Advanced Bladder Cancer
50-70 mg/m² IV cycle q3-4Weeks, depending on prior radiation therapy or chemotherapy; for heavily pretreated patients, give 50 mg/m²/cycle initially; repeat q4Weeks
Pretreatment hydration: 1-2 L fluid infused for 8-12 hr before dose
May use concomitant amifostine to decrease nephrotoxicity
Do not repeat course until SCr <1.5 mg/dL [<133 micromoles/L] or BUN <25 mg/dL [<8.93 mmol/L] or WBC >4000/mm³ AND platelets >100 k/mm³
Metastatic Ovarian Carcinoma
75-100 mg/m² IV per cycle q4Weeks with cyclophosphamide (600 mg/m² IV q4Weeks); administer sequentially
Off-label: 90-270 mg/m² intraperitoneal; retain for 4 hr before draining; repeat q3Weeks (may coadminister systemic Na thiosulfate)
Pretreatment hydration: 1-2 L fluid infused for 8-12 hr before dose
May use concomitant amifostine to decrease nephrotoxicity
Do not repeat course until SCr <1.5 mg/dL [<133 micromoles/L] or BUN <25 mg/dL [<8.93 mmol/L] or WBC >4000/mm³ AND platelets >100 k/mm³
Child Dose
Renal Dose
Renal Impairment
CrCl 10-50 mL/min: Decrease dose 50%
CrCl <10 mL/min: Contraindicated
Administration
IV Preparation
Further dilution stability is dependent on chloride ion concentration & should be mixed in solutions of NS (at least 0.3% NaCl)
Further dilution in NS, D5/½NS or D5/NS to a concentration of 0.05-2 mg/mL are stable for 72 hr at 4-25°C in combination with mannitol
May administer 12.5-50 g mannitol/L
Standard dilution: dose/250-1000 mL NS, D5W/NS or D5/½NS
IV Administration
Perform pretreatment hydration
Do not use aluminum-containing needles or IV administration sets that may come in contact with carboplatin (aluminum can react causing precipitate formation & loss of potency)
Administration rate has varied from a 15-120 min infusion, 1 mg/min infusion, 6-8 hr infusion, 24 hr infusion, or per protocol
Maximum rate of infusion: 1 mg/min in patients with CHF
When administered as sequential infusions, taxane derivatives (docetaxel, paclitaxel) should be administered before platinum derivatives to limit myelosuppression & to enhance efficacy
Contra Indications
Patients with severe renal or auditory disorder, known hypersensitivity, severe bone marrow suppression, peripheral neuropathy, pregnancy, lactation.
Precautions
Patients with renal or hepatic disorder, myelosuppression. Monitor renal, neurological and auditory function. Perform blood counts regularly. Maintain adequate hydration before and 24 hr after admin to minimise nephrotoxicity.
Lactation: excreted in breast milk; do not nurse
Pregnancy-Lactation
Interactions
Synergistic with 5-fluorouracil and etoposide. Efficacy increased and toxicity reduced when combined with radioprotecting agent WR 2721. At doses ?100 mg, cisplatin is an ideal drug to combine with other cytotoxic drugs; unlike other antineoplastic drugs, it causes little myelosuppression.
Potentially Fatal: Potentiates nephrotoxicity with aminoglycosides. Increased toxicity when combined with other cytotoxic drugs.
Adverse Effects
Side effects of Cisplatin :
>10%
Nausea (76-100%),Vomiting (76-100%),Nephrotoxicity (28-36%),Ototoxicity, especially in children (31%),Myelosuppression (25-30%),Anaphylaxis (1-20%),Alopecia
Frequency Not Defined
Cerebral herniation,Encephalopathy,Leukoencephalopathy and reversible posterior leukoencephalopathy syndrome,Seizure,Peripheral neuropathy (dose and duration dependent),Diarrhea,Electrolyte changes,Hyperuricemia,Hepatotoxicity,Local tissue irritation
Potentially Fatal: Rarely, renal damage due to inadequate hydration during therapy. Very rarely life-threatening myelosuppression. Anaphylactoid reactions (rare) and cardiac abnormalities.
Mechanism of Action
Cisplatin modifies cell cycle by interfering with DNA structure and function. Effects are most prominent during the S phase but cells are killed at all stages. Cisplatin synergises with other anticancer drugs e.g. fluorouracil. It has a narrow therapeutic margin and is highly toxic.
