Cycle length: 21 days.
Total cycles: 4.* |
| Drug | Dose and route | Administration | Given on days |
| Bleomycin¶ | 20 units/m2Δ IV per dose | Dilute in 50 mL NS◊ and administer over 10 minutes. | Day 1 |
| Etoposide | 100 mg/m2 IV per day | Dilute in 500 mL NS◊ (concentration less than 0.4 mg/mL) and administer over one hour. | Days 1 through 5 |
| Cisplatin | 20 mg/m2 IV per day | Dilute in 250 mL NS◊ and administer over two hours. Do not administer with aluminum needles or IV sets. | Days 1 through 5 |
| Pretreatment considerations: |
| Hydration | - Induction of diuresis using at least 2000 mL of NS◊ minimizes the risk of cisplatin nephrotoxicity. Fluid administration should be adequate to establish a urine flow of at least 100 mL/hour for two hours prior to and two hours after cisplatin administration.
- Refer to UpToDate topics on cisplatin nephrotoxicity.
|
| Emesis risk | - HIGH (>90% frequency of emesis).
- Refer to UpToDate topics on prevention of chemotherapy-induced nausea and vomiting in adults.
|
| Vesicant/irritant properties | - Bleomycin, etoposide, and cisplatin are classified as irritants. Cisplatin can cause significant tissue damage; avoid extravasation.[2]
- Refer to UpToDate topics on extravasation injury from chemotherapy and other non-antineoplastic vesicants.
|
| Infection prophylaxis | - Primary prophylaxis with G-CSF is not indicated.
- Refer to UpToDate topics on use of granulocyte colony stimulating factors in adult patients with chemotherapy-induced neutropenia and conditions other than acute leukemia, myelodysplastic syndrome, and hematopoietic cell transplantation.
|
| Dose adjustment for baseline liver or renal dysfunction | - Bleomycin should not be administered in patients with a baseline creatinine >2 mg/dL. A lower initial dose of cisplatin or etoposide may be needed for patients with renal or hepatic dysfunction.[2,3]
- Refer to UpToDate topics on chemotherapy hepatotoxicity and dose modification in patients with liver disease, conventional cytotoxic agents; chemotherapy hepatotoxicity and dose modification in patients with liver disease, molecularly targeted agents; and chemotherapy nephrotoxicity and dose modification in patients with renal insufficiency, conventional cytotoxic agents.
|
| Monitoring parameters: |
- CBC with differential and platelet count weekly during treatment.
|
- Basic metabolic panel (creatinine and electrolytes) prior to each treatment cycle.
|
- Liver function tests prior to each treatment cycle.
|
- Assessment of baseline PFTs, including a DLCO, should be performed prior to bleomycin treatment and repeated at intervals during therapy.
|
| Suggested dose modifications for toxicity: |
| Myelotoxicity | - Each cycle should begin on schedule regardless of the degree of myelosuppression.[1] If febrile neutropenia or thrombocytopenic bleeding occurs, a dose reduction of 25% for etoposide should be used for subsequent cycles. If neutrophil count remains ≤2500/microL or platelets remain ≤100,000/microL, G-CSF should be administered.
- Refer to UpToDate topics on use of granulocyte colony stimulating factors in adult patients with chemotherapy-induced neutropenia and conditions other than acute leukemia, myelodysplastic syndrome, and hematopoietic cell transplantation.
|
| Pulmonary toxicity | - Bleomycin can be associated with the development of life-threatening pulmonary toxicity.[4] Maximum lifetime bleomycin dose should not exceed 400 mg. Discontinue bleomycin in patients with clinical or radiographic evidence of pulmonary injury, or decline in the DLCO of 25% or more, even if asymptomatic. Do not reintroduce bleomycin to patients with any bleomycin-induced lung injury.
- Refer to UpToDate topics on bleomycin-induced lung injury.
|
| Neurologic toxicity | - Neuropathy usually is seen after cumulative doses of cisplatin beyond 400 mg/m2, although there is marked interindividual variation. Patients with mild neuropathy can continue to receive full cisplatin doses. However, if the neuropathy interferes with function, the risk of potentially disabling neurotoxicity must be weighed against the benefit of continued treatment. Peripheral neuropathies can occur with prolonged courses (four to seven months) of cisplatin. Cisplatin treatment should be discontinued with the first signs and symptoms of the development of neurotoxicity.[2,5]
- Refer to UpToDate topics on overview of neurologic complications of platinum-based chemotherapy.
|
| Renal toxicity | - Treatment in the setting of renal impairment (ie, creatinine >2 mg/dL or GFR <50 mL/min) requires a balanced discussion of the goals of treatment and the risks of cisplatin nephrotoxicity in the face of impaired renal function.
- Refer to UpToDate topics on cisplatin nephrotoxicity.
|
| If there is a change in body weight of at least 10%, doses should be recalculated. |
