DOCEtaxel 100 mg/m2 * IV infusion 1
Frequency:
21 days 
Cycles:
3 or 4 *(The phase II trials supporting this regimen used 4 cycles of FEC followed by 4 cycles of docetaxel 75 mg/m2. Given that OS and DFS are essentially equivalent whether chemotherapy is given in the adjuvant or neoadjuvant setting, there are arguments for using either 3 to 4 cycles of FEC followed by 3 to 4 cycles of docetaxel. It is the consensus of the reference committee that 3 to 4 cycles of docetaxel 100 mg/m2 be used for part 2 of the FEC-D regimen)

Cost:
~ $120 per cycle "How this cost is calculated"

The cost displayed on the protocol is intended as rudimentary guide only for the Australian context.

The cost includes antineoplastic drugs only (not antiemetics or other supportive medications), unless otherwise indicated.

Drug unit costs are taken directly from the Pharmaceutical Benefits Scheme (PBS) website (www.pbs.gov.au), MIMS Online and other sources. These costs are reviewed and updated on eviQ at 6 monthly intervals.

Where there are differing unit costs based on vial sizes and tablet strengths, the mean unit cost is used. The cost of oral continuous therapy is based on 28 day month.

The protocol cost is derived from drug dose calculations based upon a default body surface area (BSA) of 1.8 m2; weight of 75 kg; and creatinine clearance of 75 mL/min.

One off loading doses are not included in protocol cost calculations.

The cost displayed is the actual drug cost and does not necessarily reflect the cost incurred by the patient as many antineoplastic drugs are reimbursed on the PBS.

The supportive therapies (e.g. antiemetics, premedications, etc.), infusion times, diluents, volumes and routes of administration, if included, are listed as defaults. They may vary between institutions and can be substituted to reflect individual institutional policy.

Antiemetics if included in the treatment schedule are based upon recommendations from national and international guidelines. These are defaults only and may be substituted to reflect individual institutional policy. Select here for recommended doses of alternative antiemetics.

Evidence for dose modifications is limited, and the recommendations made on eviQ are intended as a guide only. They are generally conservative with an emphasis on safety. Any dose modification should be based on clinical judgement, and the individual patient’s situation including but not limited to treatment intent (curative vs palliative), the antineoplastic regimen (single versus combination therapy versus chemotherapy versus immunotherapy), biology of the cancer (site, size, mutations, metastases), other treatment related side effects, additional co-morbidities, performance status and patient preferences. Suggested dose modifications are based on clinical trial findings, product information and reference committee consensus. Non-haematological gradings are based on Common Terminology Criteria for Adverse Events (CTCAE) unless otherwise specified. Renal and hepatic dose modifications have been standardised where possible. For more information see dosing considerations & disclaimer.

Note:

  • All dose reductions are calculated as a percentage of the starting dose.
  • Administration of granulocyte colony-stimulating factor (G-CSF +/- antibiotics) is at clinician discretion and local hospital guidelines.

  Interaction Clinical management
Warfarin Antineoplastic agents may alter the anticoagulant effect of warfarin Monitor INR regularly and adjust warfarin dosage as appropriate; consider alternative anticoagulant (e.g. LMWH or unfractionated heparin)
Digoxin Antineoplastic agents can damage the lining of the intestine; affecting the absorption of digoxin Monitor digoxin serum levels; adjust digoxin dosage as appropriate
Antiepileptics Both altered antiepileptic and antineoplastic levels may occur, possibly leading to loss of efficacy or toxicity Where concurrent use of an enzyme-inducing antiepileptic cannot be avoided, monitor antiepileptic serum levels for toxicity, as well as seizure frequency for efficacy; adjust dosage as appropriate.
Also monitor closely for efficacy of the antineoplastic therapy
Antiplatelet agents and NSAIDs Increased risk of bleeding due to treatment related thrombocytopenia Avoid or minimise combination.
If combination deemed essential, (e.g. low dose aspirin for ischaemic heart disease) monitor for signs of bleeding

Results from the National Surgical Adjuvant Breast and Bowel Project (NSABP) protocol B-18 trial demonstrated an increased likelihood of Breast Conservation Surgery (BCS) in breast cancer patients treated with a neoadjuvant anthracycline-based regimen.r Although the B-18 trial did not demonstrate a survival advantage in patients treated with preoperative chemotherapy, it established pathological complete response (pCR) as a prognostic marker for disease-free survival (DFS).

FEC-D has been successfully utilised in the adjuvant setting with eight-year follow-up data showing a 4% absolute benefit in DFS and 5% benefit in OS (Link to the evidence for adjuvant FEC-D).

A search of the literature did not find strong phase III evidence for use of FEC-D in the neoadjuvant setting. Ohno et alr and von Minckwitz et alr studied the efficacy of neoadjuvant (F)EC-D but in varying combinations with capecitabine.

There were three phase II trials directly studying neoadjuvant FEC-D.rrr The expert reference panel supported publication of the protocol on the basis of the information summarised below. The Japan Breast Cancer Research Group (JBCRG) 01 trial, published in 2008, was the largest study to date evaluating neoadjuvant chemotherapy in this patient populationrr where the Quasi-Pathologic Complete Response (QpCR – no invasive tumour or only focal residual cells) rate was 25%. Within 40 months median follow-up, 3-year DFS was estimated at 98% for patients with QpCR versus those without (89%, HR 0.38 [95% C.I. 0.09 – 0.84]). The overall clinical response rate was 75%. 85% of patients achieved breast conservation. HER-2 status and response to FEC were independent predictors of QpCR. Grade 3/4 neutropaenia was the common adverse event.

In order to achieve a higher pCR with an improved safety profile, the JBCRG-03 trial, published in 2011,r assessed the efficacy of the reverse sequence of the chemotherapy used in the JBCRG-01 trial, with 4 cycles of docetaxel (75 mg/m2 q3w) followed by 4 cycles of 5-fluorouracil 500 mg/m2, epirubicin 100 mg/m2, and cyclophosphamide 500 mg/m2 q3w in patients with early-stage breast cancer. The primary endpoint was the pathological complete response (pCR) rate defined for the breast alone, assessed by a central review committee. Secondary endpoints included clinical response and safety. Of the 132 patients assessable for pathologic response, 23% experienced a pCR and 6% had a near pathological complete response (few remaining cancer cells), resulting in a QpCR of 29%. Clinical response rate following the initial docetaxel regimen was 64%. The overall clinical response rate was 79%. Breast-conserving surgery was performed in 79% of patients. More patients with triple-negative disease experienced a pCR (14/29, 48 %) versus those with other molecular subtypes. The safety profile was acceptable.

Note that all the phase II trials used 4 cycles of FEC and 4 cycles of docetaxel (75 mg/m2). Given that OS and DFS are essentially equivalent whether chemotherapy is given in the adjuvant or neoadjuvant setting, there are arguments for using either the 6 or 8 cycles of FEC-D.

Evidence for the “FEC” portion of the regime is provided by Mouret-Reynier et al,r where pCR rates were 15-25% depending on classifications.

Evidence for the “D” portion of the regime is provided by the NSABP B-27 trial. The addition of sequential docetaxel to AC doubled the pCR rate and increased the clinical complete response (cCR) rate but did not improve disease free survival (DFS) and overall survival (OS) compared to AC alone. (Link to the evidence for Breast neoadjuvant AC followed by docetaxel).

Toxicity

A summary of the toxicities associated with this protocol are included in the table below. The most clinically significant toxicity for both parts of the treatment was myelosuppression. In the JBCRG-01 trial, G-CSF was administered at investigators' discretion in 10.5%, 8.2% and 9.4% of treatment cycles of FEC (part 1), docetaxel (part 2) and both (part 1 and 2) respectively.r For non-hematologic toxicities of any grade, rash, sensory neuropathy, oedema, muscle pain and joint pain occurred more frequently during docetaxel treatment than with FEC. Conversely, the frequency of gastrointestinal symptoms, such as nausea, vomiting and anorexia, was higher with FEC.r
