Dates to Remember

Breast cancer is a leading cause of death in Canadian women. Although the clinical utility of breast imaging in the

detection, diagnosis, and treatment monitoring of breast cancer is well established, the limitations of x-ray

mammography, ultrasound imaging and other breast imaging modalities are well described in the medical literature.

Near infrared diffuse optical spectroscopy (DOS) and diffuse optical tomography (DOT) are non-invasive techniques

that quantitatively measure near-infrared absorption and scattering spectra across tissue. Although the technique has

relatively low resolution compared to conventional imaging modalities, diffuse light contains functional information that

is unavailable from structural imaging. Specifically, DOS / DOT provides information regarding the concentration and

molecular status of intrinsic tissue absorbers such as oxyhemoglobin, deoxyhemoglobin, water and lipids. The cover

shows a transverse image of a breast cancer patient imaged using DOT demonstrating an enhanced region of

oxyhemoglobin within the tumour volume as determined by magnetic resonance imaging (MRI).

Currently, the Czarnota lab at the Sunnybrook Health Science Centre is exploring the use of DOS / DOT for use in

breast cancer patients as a tool to monitor treatment efficacy. The study investigates optical tissue characteristics of

breast tumours during neoadjuvant breast cancer treatment using a clinically approved DOS / DOT hybrid imaging

system to determine if it is possible to distinguish responders from non-responders as assessed by MRI and clinical

pathological outcome. The ultimate goal is to use optical imaging with ultrasound as an early predictor of partial or

complete pathological response in women receiving treatment with neoadjuvant chemotherapy for locally advanced

breast cancer. Images provided by Dr. Hani Soliman and Dr. Gregory Czarnota, Odette Cancer Centre, Toronto ON
