Disease Site
Breast

Intent
Neoadjuvant
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.


Rationale and Uses

Neoadjuvant treatment for non-metastatic breast cancer (inoperable locally advanced, inflammatory or to downsize tumour pre-surgery) or Adjuvant therapy for node-positive and high risk node-negative breast cancer patients.

 

 

 

 

Trastuzumab may be used concurrently with paclitaxel or after completion of paclitaxel in:

  • high-risk (node-positive or negative with tumour > 1cm) HER-2 positive breast cancer
  • or small tumours (≤1 cm, node negative) in HER-2 positive breast cancer as part of the evidence building program

C - Cycle Frequency

REPEAT EVERY 14 DAYS:  AC X 4 cycles then Paclitaxel (Taxol®) X 4 cycles

Q3 Weeks or Weekly Trastuzumab:  Refer to TRAS (Breast - Adjuvant) regimen for details.

 
D - Premedication and Supportive Measures

Antiemetic Regimen:

High (AC)
Low (Paclitaxel)


Febrile Neutropenia Risk:

High

Give filgrastim 5 mcg/kg/day SC on days 3 to 10, in AC and PACL cycles.

Also see G-CSF recommendations.


Other Supportive Care:

  • Paclitaxel: Patients should be pretreated with a corticosteroid as well as an antihistamine and a H2 Blocker: For example:
    • Dexamethasone 20mg PO 12 & 6 hours or 20mg IV 30 minutes before Paclitaxel
    • Diphenhydramine 50mg IV 30 minutes before Paclitaxel administration
    • Ranitidine 50mg IV 30 minutes before Paclitaxel administration
 
E - Dose Modifications

Doses should be modified according to the protocol by which the patient is being treated. The following recommendations have been adapted from clinical trials or product monographs and could be considered.
