Clinical Trial Summary

Neoadjuvant chemotherapy (NAC) is the first line treatment for locally advanced breast cancer (BC). Besides making breast conserving surgery feasible, its main aim is to achieve a pathological complete response (pCR). Previous studies demonstrated that a pCR correlated with a higher disease-free survival. Tumor response may vary among different BC subtypes and only 30% of BC respond completely to NAC. Treating chemo-resistant disease with NAC may cause patient harm due to drug toxicity and surgery delay.

It is therefore very important to promptly identify those women who will not benefit from NAC.

Mammography and ultrasound proved ineffective in monitoring changes in lesion size due to therapy-induced fibrosis. MRI is the most accurate imaging technique for assessing early clinical response by measuring tumor size, however its accuracy is lower post NAC. This necessitates the need for a new technique able to non invasively assess the effectiveness of NAC. Optical techniques are sensitive to the biological changes that occur within the tumor after NAC administration. These changes occur prior to tumor size reduction.

Optically estimated total hemoglobin concentration correlates with the histological analysis of vasculature as well as with tumor-associated angiogenesis which can affect tumor changes during NAC. Other promising biomarkers related to tissue composition (water, lipid, collagen content) and structure (scattering) may also be evaluated by optical techniques.

The aim of the study is to monitor the effectiveness of NAC in BC patients with a near infrared spectroscopic imaging platform which allows to non-invasively detect changes in vascularization and size of BC and to characterize the presence of temporal changes in regional concentrations of relevant biomarkers (oxy- and deoxyhemoglobin, water, lipid and collagen concentration, scattering) within tissue during NAC.

This optical imaging technique will provide a non-invasive, safe and relatively inexpensive tool to monitor patients' response to NAC and to predict their outcome.

Description:

In this study, an accurate, reliable, non-invasive modality with good patient tolerance will be tested to predict response to NAC in order to tailor the medical and surgical treatment.

The aim of this project is to monitor the effectiveness of NAC in BC patients with a new near infrared spectroscopic imaging platform which allows to non-invasively detect changes in size, vascularization and blood oxygenation in tumors and to characterize the presence of temporal changes in regional concentrations of relevant biomarkers like oxy- and deoxyhemoglobin, water, lipid and collagen and scattering in the tissue during NAC. This optical imaging tool will allow a non-invasive, safe and relatively inexpensive monitoring of NAC and prediction of patients' outcome.

A single-site, national, non-comparative, non-randomized study will be conducted at the San Raffaele Hospital in Milan in collaboration with the Politecnico di Milano. The medical device is a prototype developed by Politecnico di Milano.

Twenty adult women with a recent diagnosis of breast cancer and candidate for NAC, who fulfil the inclusion criteria and agree to voluntary participate in the study under informed consent, will be enrolled.

Besides assessing the response to neoadjuvant chemotherapy using conventional imaging evaluation (x-ray mammography and breast ultrasound prior to commencement/baseline, half way through and on completion of NAC; contrast-enhanced MRI prior to commencement/baseline and on completion of NAC), the patients enrolled will be evaluated with optical imaging at the following six selected time points (prior to commencement of NAC/baseline, 2-5 days post-NAC, 6-8 days post-NAC, 2 weeks post-NAC, half-way through and on completion of NAC).

A preliminary phase will be performed on the first 5 patients out of the 20 patients enrolled, in order to evaluate the potential artefacts related to a recent breast biopsy and to the positioning of a clip. In this preliminary phase, 2 additional optical evaluations will be carried out, one prior to the breast biopsy and one after the positioning of the clip.

Patients are enrolled in the study for the entire duration of NAC. No follow-up is required and patients will be followed according to the regular clinical standard of care. Moreover, the outcome of the optical investigation does not affect the treatment and management of the women enrolled in the study.

The duration of enrolment of the study is expected to be approximately 12 months. The study will end when the last patient enrolled will complete her chemotherapy treatment.
