Regimen: Docetaxel, Carboplatin and Trastuzumab (TCH i.e. Taxotere® Carboplatin, Herceptin®) for Early Breast Cancer Indication Regimen details Administration Approved for the treatment of early and locally advanced breast cancer in patients with lymph node positive, HER2 positive breast cancer where an anthracycline is contra-indicated. Day Drug Dose Route 1 Docetaxel 75mg/m2 IV 1 Carboplatin AUC6 IV 1 Trastuzumab* 8mg/kg IV loading then 6mg/kg *See protocol ASWCS10 BR018 (adjuvant trastuzumab) for monitoring guidelines. Order of administration: trastuzumab first, docetaxel second, carboplatin third. Docetaxel is administered in a 250ml PVC-free sodium chloride 0.9% bag over 60 minutes. Doses >190mg should be diluted in 500ml (maximum concentration 0.74mg/ml). Carboplatin is administered in 500ml 5% dextrose (or 0.9% sodium chloride) over 60 minutes. Avoid any device containing aluminium that may come into contact with Carboplatin. Frequency Controlled document Patients should be observed closely for hypersensitivity reactions, particularly during the first and second infusions. Hypersensitivity reactions may occur within a few minutes following the initiation of the infusion of docetaxel, carboplatin or trastuzumab. Facilities for the treatment of hypotension and bronchospasm must be available. If hypersensitivity reactions occur, minor symptoms such as flushing or localised cutaneous reactions do not require discontinuation of therapy. The infusion may be temporarily interrupted and when symptoms improve re-started at a slower infusion rate. Chlorphenamine 10mg iv may be administered. Severe reactions, such as hypotension, bronchospasm or generalised rash/erythema require immediate discontinuation of docetaxel and appropriate therapy. Patients who have developed severe hypersensitivity reactions should not be re-challenged with docetaxel. Every 21 days 6 cycles chemotherapy 18 cycles of Trastuzumab Document No Version Number ASWCS10 BR021 1.1.a Last printed 19/01/2011 *ONLY VALID ON DATE OF PRINTING* Page 1 of 5 Premedication Docetaxel is an exfoliant (Group 4) Carboplatin is an irritant (Group 3) Trastuzumab is neutral (Group 1) Dexamethasone 8mg bd PO for 3 days, starting the day before each cycle of chemotherapy. Patient should receive 3 doses prior to treatment. In the case where 3 doses have not been taken, dexamethasone 16 20mg IV should be administered 30-60 minutes prior to chemotherapy and the remaining 3 oral doses should be administered as per standard. Emetogenicity This regimen has moderate-high emetic potential – refer to local protocol Additional recommended supportive medication Mouthwashes as per local policy H2 antagonist or Proton Pump Inhibitor if required Consider GCSF if patients develop febrile neutropenia Give diclofenac 50mg tds from Days 1-5 if the patient develops myalgia/arthralgia. Prednisolone 5-10mg od from Days 2-6 and/or gabapentin 300mg stat Day 0, 300mg bd Day 1 & 300mg tds Days 2-7 are alternative agents to use if myalgia/arthralgia persists ECHO* Pre-treatment and subsequent monitoring of cardiac function is required. It is recommended that this follows UK guidelines with an echocardiogram pre chemotherapy and at 4 and 8 months. Further assessment after completion of trastuzumab is recommended for patients requiring cardiovascular intervention.

Carboplatin and Trastuzumab do not normally require dose reductions in hepatic impairment.
