DOSAGE AND ROUTES
Calculator
Breast cancer with axillary node involvement following resection of the primary tumor in combination with cyclophosphamide and fluorouracil

• Adult:
IV
100 mg/m
2
on day 1 with fluorouracil and cyclophosphamide (FEC regimen) every 21 days × 6 cycles or 60 mg/m
2
on days 1 and 8 with oral cyclophosphamide and fluorouracil every 28 days × 6 cycles.

Breast cancer in combination with cyclophosphamide

• Adult:
IV
60 mg/m
2
day 1 with cyclophosphamide (500 mg/m
2
IV day 1), repeated every 21 days × 8 cycles or a higher-dose regimen of epirubicin 100 mg/m
2
IV day 1 with cyclophosphamide (830 mg/m
2
IV day 1), every 21 days × 8 cycles

Dosage adjustments based upon hematologic and non-hematologic toxicities

• Nadir platelet counts <50,000/mm
3
, absolute neutrophil counts (anc) <250/mm
3
, neutropenic fever, or grades 3/4 non-hematologic toxicities:
Day 1 dose in subsequent cycles should be reduced by 25% of the previous dose

• For patients receiving divided-dose epirubicin (i.e., day 1 and 8):
Day 8 dose should be reduced by 25% of the day 1 dose if the platelet counts are 75,000–100,000/mm

3
; if day 8 platelet counts are <75,000/mm
3
, ANC <1000/mm
3
, or Grade 3/4 non-hematologic toxicity has occurred, omit the day 8 dose

Hepatic dose

• Adult:

Administer:

• 
Antiemetic 30-60 min before product to prevent vomiting

• 
Allopurinol or sodium bicarbonate to maintain uric acid levels, alkalinization of urine, monitor electrolytes

 

Black Box Warning:

To be used by a clinician experienced in giving cytotoxic products

 

Black Box Warning:

Do not use IM/SUBCUT because of severe tissue necrosis

• 
Give IV, do not give IM, subcut; a vesicant; if extravasation occurs stop and complete via another vein, preferably in another limb; avoid infusion into veins over joints or in extremities with compromised venous or lymphatic drainage

• 
Rapid injection can cause facial flushing or erythema along the vein; avoid administration time of <3 min

• 
Product should be given to those with neutrophils ≥1500/mm
3
, platelet count ≥100,000/mm
3
, and non-hematologic toxicities recovered to ≤grade 1

• 
When refrigerated, the preservative-free, ready-to-use solution can form a gelled product and will return to solution after 2–4 hr at room temperature

• 
Visually inspect for particulate matter and discoloration before use

IV route

• 
Use cytotoxic handling procedures; pregnant women must not handle product

• 
Reconstitute 50 mg and 200 mg powder for injection vials with 25 ml and 100 ml, respectively, of Sterile Water for Injection (2 mg/ml), shake vigorously for up to 4 min; reconstituted sols are stable for 24 hr when stored refrigerated and protected from light or at room temperature in normal light

• 
Solution can be further diluted with Sterile Water for Injection

IV INJ route

• 
Give doses of 100–120 mg/m
2
into tubing of a freely flowing 0.9% sodium chloride (NS) or D
5
W IV inf over 15–20 min; the infusion time may be decreased, proportionally, in those who require lower doses; infusion times <3 min are not recommended

• 
Direct injection into the vein is not recommended because of the risk of extravasation; avoid use with any solution of alkaline pH because hydrolysis will occur

IV INF route

• 
Dilute dose in 0.9% sodium chloride (NS) or D
5
W, infuse over 30–60 min, avoid use with any solution of alkaline pH because hydrolysis will occur

NURSING CONSIDERATIONS
Assess:

 

Black Box Warning:

Bone marrow depression (severe):
CBC, differential, platelet count weekly; withhold product if baseline neutrophil ≤1500/mm
3
; leukocyte nadir occurs 10-14 days after administration, recovery by day 21; notify prescriber of results

• 
Infection:
treat before receiving this product if regimens >120 mg/m
2
, prophylactic antibiotics should be given (trimethaprin-sulfamethoxazole or a quinolone)

• 
Blood, urine uric acid levels; swelling, joint pain primarily in extremities; patient should be well hydrated to prevent urate deposits

• 
Renal disease: BUN, serum uric acid, urine CCr, electrolytes before, during therapy; I&O ratio; report fall in urine output to <30 ml/hr; dosage adjustment needed if serum creatinine >5 mg/dl

• 
Increased fluid intake to 2-3 L/day to prevent urate, calculi formation

 

Black Box Warning:

Hepatic studies before, during therapy: bilirubin, AST, ALT, alk phos as needed or monthly

 

Black Box Warning:

Heart failure:
B/P, pulse, character, rhythm, rate, ABGs, ECG, LVEF, MUGA scan, or ECHO; watch for ST-T wave changes, low QRS and T, possible dysrhythmias (sinus tachycardia, heart block, PVCs); identify cumulative amount of anthracycline received (lifetime)

• 
Bleeding: hematuria, guaiac, bruising, or petechiae, mucosa or orifices q8hr

• 
Effects of alopecia on body image; discuss feelings about body changes

 

Black Box Warning:

Extravasation (vesicant):
local irritation, pain, burning, necrosis at inj site, discontinue and start at another site

• 
GI symptoms: frequency of stools, cramping

Evaluate:

• 
Therapeutic response: decreased tumor size, spread of malignancy

Teach patient/family:

• 
That hair may be lost during treatment; that wig or hairpiece may make patient feel better; that new hair may be different in color, texture; new hair growth occurs in ≤3 mo after treatment

• 
To avoid crowds, persons with infections when granulocyte count is low

• 
That contraceptive measures recommended during therapy and for 4 mo thereafter for men and women; pregnancy (D)

• 
To avoid vaccinations because reactions may occur; to avoid cimetidine during therapy

• 
That urine may appear red for 2 days

• 
To avoid OTC medications, supplements unless approved by prescriber
