Docetaxel Followed by Surgery in Treating Women With Stage II or Stage III Breast Cancer

21 april 2012 uppdaterad av: Bapsi Chak, MD, Vanderbilt-Ingram Cancer Center

Pilot Study of Neoadjuvant Dose Dense Docetaxel With Correlative Molecular Studies in Stage II/III Breast Cancer

RATIONALE: Dose-dense scheduling with (peg)filgrastim support may improve the clinical and pathologic complete response rate (pCR) and safety profile of single agent neoadjuvant docetaxel therapy.

PURPOSE: To evaluate whether dose-dense scheduling with (peg)filgrastim support may improve the clinical and pathologic complete response rate (pCR) and safety profile of single agent neoadjuvant docetaxel therapy. To determine the changes in molecular markers that occurs with single agent docetaxel, tissue will be obtained at the end of the four cycles of docetaxel (either by repeat biopsy or definitive surgery).

Detaljerad beskrivning

OBJECTIVES:

Primary

  • Pathologic complete response rate (pCR) of dose dense docetaxel in the neoadjuvant setting.

Secondary

  • Safety and toxic effects of this regimen in these patients.
  • Tumor response rate (as measured by ultrasound) in patients treated with this regimen.
  • Determine whether early changes in markers of cell cycle position, proliferation, or apoptosis correlate with pathologic complete response rate in these patients.
  • Determine whether the molecular profile that predicts for chemoresponsiveness also predicts for response to radiotherapy (as measured by local recurrence) in these patients.
  • Determine whether tumors that demonstrate the greatest degree of change in protein expression patterns from pre- to post-docetaxel treatment will also be those that are most sensitive to chemotherapy (as measured by pathologic response rate) in these patients.

OUTLINE: This is a nonrandomized, open-label, pilot study.

  • Tissue Collection: Patients undergo tumor core biopsy (6-8 cores) and blood collection prior to initiating neoadjuvant docetaxel.
  • Neoadjuvant docetaxel with hematopoietic support: Patients receive docetaxel IV over 1 hour on day 1. Patients also receive pegfilgrastim subcutaneously (SC) on day 1 or 2 of each course OR filgrastim (G-CSF) or sargramostim (GM-CSF) SC daily beginning between day 2-4 of each course and continuing until blood counts recover. Treatment repeats every 14 days for up to 4 courses in the absence of disease progression or unacceptable toxicity.
  • Surgery: Within 4-6 weeks after completion of neoadjuvant docetaxel, patients undergo definitive surgery.

Patients undergo tumor biopsy and blood collection periodically for pharmacokinetic, genetic, and molecular biomarker correlative studies. Samples are examined for changes in p21 protein expression (and/or p21 phosphorylation) and the protein expression profile.

After completion of study treatment, patients are followed at least every 6 months for 3 years and then annually thereafter.

PROJECTED ACCRUAL: A total of 50 patients will be accrued for this study.

  • Histologically or cytologically confirmed invasive carcinoma of the breast by core biopsy
  • Tumor ≥ 2 cm in greatest dimension(may be either node positive or node negative disease
  • Patients with non-metastatic breast cancer who are in the judgment of the treating medical oncologist considered to be of sufficiently high risk to warrant adjuvant chemotherapy

    • Patients with internal mammary, supraclavicular and/or axillary node involvement are eligible. Patients with inflammatory breast cancer are eligible
    • Patients with T0 disease but palpable and measurable adenopathy are eligible for this trial. All sites of disease should be noted and followed

  • Women of child-bearing potential, must have a negative serum pregnancy test and must use effective contraception for the duration of the study and for at least 6 months after completion of study treatment
  • Patients with prior malignancies are eligible if they have been disease free for ≥ 5 years. Patients with curative treatment of non-melanomatous skin cancer, carcinoma in situ of the cervix, contralateral DCIS treated with mastectomy are eligible even if it is diagnosed in < 5 years.

PRIOR CONCURRENT THERAPY:

  • No prior anthracycline or taxane-based chemotherapy. Patients who received chemoprevention are eligible if the chemopreventive agent has been discontinued for at least one year prior to enrollment in the current study.
  • At least 1 year since prior tamoxifen for breast cancer prevention

Exclusion:

  • Prior radiotherapy to the ipsilateral breast

    • Patients who have had radiation to the contralateral breast are eligible
  • Evidence of distant metastatic disease (i.e., lung, liver, bone, brain)
  • Pregnant of breastfeeding

  • Patients receiving an investigational anticancer drug within 3 weeks of registration
  • Patients with serious medical illness that in the judgment of the treating physician, places the patient at risk.

Tidsram
Safety Profile Based on Number of Patients With Each Worst-grade Toxicity
Tidsram: Through 30 days after completion of treatment
Not all participants necessarily have an adverse event, thus not everyone will be accounted for in worst-grade toxicities. Likewise, one participant can potentially have more than one event in various grades 1-5 which accounts for the difference in number of patients analyzed and total number in the worst-grade toxicity tables. Tables represent the number of patients with worst-grade toxicity at each of five grades (grade 1, least severe; to grade 5, most severe) following NCI Common Toxicity Criteria
Through 30 days after completion of treatment
Tumor Response as Measured by Ultrasound
Tidsram: At screening, 8 weeks and at surgery (within 14-21 days)
Progressive disease (PD): >=20% increase in sum of longest diameter (LD) of target lesion(s), taking as reference smallest sum LD recorded since treatment started. Complete response (CR): disappearance of all target lesions. Partial response (PR): >=30% decrease in sum of LD of target lesion(s), taking as reference baseline sum LD. Stable disease (SD): neither sufficient shrinkage to qualify as PR nor sufficient increase to qualify as PD.
At screening, 8 weeks and at surgery (within 14-21 days)
