Study Details

Brief summary:

We have previously demonstrated that high-frequency ultrasound and spectroscopy, and recently conventional-frequency ultrasound and spectroscopy may be used to detect cell death in vitro, in situ and in vivo. The method can detect different forms of cell death and has been demonstrated to be sensitive to apoptotic, necrotic and mitotic cell death. The objectives of this study are to evaluate the use of ultrasound imaging and spectroscopy as a predictive marker of advanced tumour response to combined chemotherapy and radiotherapy. Since neoadjuvant treatments may also act on tumour vasculature to "normalize" it we will also evaluate blood-vessel imaging by standard Doppler-imaging and with standard higher-resolution imaging using clinically approved microbubble contrast agents.

The main goal, as described above, is to select the best ultrasound spectroscopy parameter to use as an early predictor of pathological complete response.

INCLUSION CRITERIA:

The following criteria are necessary for study participation:

1. Histologically or cytologically confirmed breast carcinoma, stage I-IV, which has not been treated with any first-line therapy and will be treated with neoadjuvant chemotherapy or neoadjuvant combined chemo-radiotherapy.
2. Measurable disease by ultrasound, or MRI performed within 28 days prior to treatment.
3. Eastern Co-operative Oncology Group (ECOG) Performance Status of 0 or 1.
4. Life expectancy of at least 6 months.
5. Adequate bone marrow, liver and renal function as assessed by the following laboratory. Requirements to be conducted within 7 days prior to dosing:

6. Patients should have the ability to understand and the willingness to sign a written informed consent document. Signed informed consent must be obtained prior to any study specific procedures.

EXCLUSION CRITERIA

The following conditions will exclude women from participation:

1. Chemotherapy, radiotherapy, or major surgery within 4 weeks prior to registering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks prior to registration.
2. Receiving any other investigational agents.
3. Known brain metastases.
4. History of allergic reactions attributed to compounds of similar chemical or biologic composition.
