Blood Oxygen Level Dependent Magnetic Resonance Imaging (BOLD MRI) and Fluorothymidine Positron Emission Tomography (FLT PET) in Patients With Locally Advanced Breast Cancer Undergoing Neoadjuvant Chemotherapy

Not Applicable
Completed
Conditions
Locally Advanced Breast Cancer (LABC)
Interventions
Procedure: FLT PET and BOLD MRI scan
Registration Number
NCT01240681
Lead Sponsor
Ontario Clinical Oncology Group (OCOG)
Brief Summary

The objective of this pilot study is to determine the effectiveness of Fluorothymidine Positron Emission Tomography (FLT PET) and Blood Oxygen Level Dependent Magnetic Resonance Imaging (BOLD MRI) in assessing tumour response to neoadjuvant chemotherapy (NA CT) in women with locally advanced breast cancer.

Status
COMPLETED
Sex
Female
Target Recruitment
32
Inclusion Criteria
  • Histologic proof of breast cancer (invasive ductal or lobular carcinoma). Breast sarcoma and lymphoma are not eligible.
  • Clinical diagnosis of locally advanced breast cancer (Stage IIB (T3,N0,M0), Stage IIIA, IIIB, or IIIC, according to American Joint Committee on Cancer (AJCC) Tumour-Node-Metastasis (TNM) Cancer Staging), including inflammatory breast cancer.
  • Ability to undergo neoadjuvant chemotherapy.
Exclusion Criteria
  • Evidence of metastatic disease (identified on chest x-ray, liver ultrasound, bone scan or other imaging tests);
  • Previous chemotherapy or hormonal therapy for breast cancer;
  • Significant concurrent medical problems that result in the patient being unfit for surgery (e.g. uncontrolled diabetes, active cardiac disease, severe chronic obstructive pulmonary disease);
  • Known pregnancy or lactating female (e.g. positive serum beta human chorionic gonadotropin (B-hCG) pregnancy test);
  • Inability to lie supine for imaging with Positron Emission Tomography (PET);
  • Any contraindication to undergoing Magnetic Resonance Imaging (MRI) or PET;
  • Currently receiving Antabuse;
  • Inability to provide informed consent (e.g. dementia or severe cognitive impairment).

Primary Outcome Measures
NameTimeMethod
Clinical response (partial and complete)6 months (approximately)

Partial clinical response refers to at least a 50% reduction in the dimensions of the tumour mass and a complete clinical response refers to complete absence of the mass on physical exam, as well as absence of inflammation, ulceration and peau d'orange.

Secondary Outcome Measures
NameTimeMethod
Pathologic response6 months (approximately)

Using the Residual Cancer Burden (RCB) index the pathologic response will be divided into categories. The three categories are complete response, near complete response and chemotherapy resistance. A complete pathologic response (pCR) refers to complete absence of invasive cancer.

Imaging Quantification6 months (approximately)

Fluorothymidine Positron Emission Tomography (FLT PET) and Blood Oxygen Level Dependent (BOLD) MRI quantification of tumor responses to predict which patients are likely to achieve a pathologic complete response.
