    Trastuzumab - Adjuvant Treatment for HER2_neu-Overexpressing Primary Breast Cancer
A - Regimen Name

CRBPDOCE+PERT+TRAS Regimen
CARBOplatin-DOCEtaxel-Pertuzumab-Trastuzumab


Disease Site
Breast

Intent
Curative
Adjuvant

Regimen Category
Evidence-informed :

Regimen is considered appropriate as part of the standard care of patients; meaningfully  improves outcomes (survival, quality of life), tolerability or costs compared to alternatives (recommended by the Disease Site Team and national consensus body e.g. pan-Canadian Oncology Drug Review, pCODR).  Recommendation is based on an appropriately conducted phase III clinical trial relevant to the Canadian context OR (where phase III trials are not feasible) an appropriately sized phase II trial. Regimens where one or more drugs are not approved by Health Canada for any indication will be identified under Rationale and Use.

This Regimen Abstract is an abbreviated version of a Regimen Monograph and contains only top level information on usage, dosing, schedule, cycle length and special notes (if available). Information in regimen abstracts is accurate to the extent of the ST-QBP regimen master listings, and has not undergone the full review process of a regimen monograph. Full regimen monographs will be published for each ST-QBP regimen as they are developed.

C - Cycle Frequency

REPEAT EVERY 21 DAYS

Docetaxel and Carboplatin: For a usual total of 6 cycles unless disease progression or unacceptable toxicity occurs

High

Consider G-CSF prophylaxis for patients at high risk of febrile neutropenia. See G-CSF recommendations.


Other Supportive Care:

  • Dexamethasone 8 mg bid po for 3 days starting 1 day prior to docetaxel (prevent anaphylaxis / fluid retention.)

Calvert Formula

                    DOSE (mg) = target AUC X (GFR + 25)

  • Target AUC of 4 to 6 mg/mL·min (previously treated patients) or 6 to 8 mg/mL·min  (previously untreated patients)
  • AUC = product of serum concentration (mg/mL) and time (min)
  • GFR (glomerular filtration rate) expressed as measured Creatinine Clearance or estimated from Serum Creatinine (by Cockcroft and Gault method or Jelliffe method)
