Brief Summary:
This study aims to investigate if lipid composition mapping using magnetic resonance imaging could improve early and accurate cancer detection in genetic mutation carriers at high risk of breast cancer. It is hypothesised that there is a significant difference in the extent of spatial variation in lipid composition in breast from MRI between genetic mutation carriers and patients with breast cancer.

Condition or disease Intervention/treatment
Breast Cancer Procedure: Magnetic resonance imaging (MRI)

Detailed Description:

Breast cancer is a major and expanding societal challenge despite the significant improvement in survival rate. The current screening method has been shown to lead to overtreatment, prompting the development of accurate early detection approaches targeting underlying clinical features. Patients with BRCA1/2 and TP53 genes are at risk of breast cancer and receive annual surveillance. However, the current diagnostic approach relies on detecting the changes to the growth of tumour only once cancer is well under development. Detecting earlier changes to breast fatty tissue may detect patients earlier and more accurately.

Breast fatty tissue is composed of different fatty acids and a difference in the fatty acid composition has been shown in BRCA1/2 gene carriers. Measurement of lipid composition can be achieved using a specialist magnetic resonance spectroscopy method, but is limited to sampling a small area and is unable to provide the full picture of lipid composition distribution during early cancer growth. Recently, magnetic resonance chemical shift imaging, through combining magnetic resonance spectroscopy and imaging approaches, has been developed to provide lipid composition maps of the entire breast.

The investigators propose to perform lipid mapping in the breasts of 20 genetic mutation carriers at high risk of breast cancer and 20 patients with newly diagnosed breast cancer to examine the sensitivity of the method. The overarching aim is to improve early and accurate cancer detection in genetic mutation carriers at high risk of breast cancer through the assessment of whole breast lipid composition.

Group/Cohort Intervention/treatment
High-risk
Female participants confirmed to be BRCA1/2 or TP53 gene carriers
Procedure: Magnetic resonance imaging (MRI)
MRI scan uses radio waves in a magnetic field to obtain images of the breast. It is non-invasive and participants will not be exposed to harmful radiation. An image contrast agent will be used to enhance image clarity. Participants will be scanned lying face-down on a specially-designed bed and ear protectors will be provided to screen out background noise.

Patients
Female participants confirmed to have invasive ductal carcinoma of the breast
Procedure: Magnetic resonance imaging (MRI)
MRI scan uses radio waves in a magnetic field to obtain images of the breast. It is non-invasive and participants will not be exposed to harmful radiation. An image contrast agent will be used to enhance image clarity. Participants will be scanned lying face-down on a specially-designed bed and ear protectors will be provided to screen out background noise.




Primary Outcome Measures :
  1. Saturated fatty acids in breasts of patients and high-risk group [ Time Frame: Baseline ]

    Saturated fatty acids (SFA) from tumour border and fatty tissue in patients and fibroglandular and fatty tissue in high-risk group

    SFA will be measured in percentage (%)


  2. Monounsaturated fatty acids in breasts of patients and high-risk group [ Time Frame: Baseline ]

    Monounsaturated fatty acids (MUFA) from tumour border and fatty tissue in patients and fibroglandular and fatty tissue in high-risk group

    MUFA will be measured in percentage (%)


  3. Polyunsaturated fatty acids in breasts of patients and high-risk group [ Time Frame: Baseline ]

    Polyunsaturated fatty acids (PUFA) from tumour border and fatty tissue in patients and fibroglandular and fatty tissue in high-risk group

    PUFA will be measured in percentage (%)
