Background and study aims
Breast cancer is the most common cancer in the UK. 15 out of 100 newly diagnosed cancers in the UK are breast cancers. Survival for breast cancer is generally good, especially if a patient is diagnosed early. The benefits of finding breast cancer early are clear and often result in requiring less treatment with a greater likelihood of cure. Symptoms of breast cancer include a lump that can be felt, skin/nipple changes and nipple discharge. If patients already have symptoms, they are usually referred to a one-stop breast clinic. This is where a patient will have the gold standard investigation which includes several tests known as ‘triple assessment’. Patients will have an examination of their breasts alongside imaging (x-ray mammogram or ultrasound), and a tissue sample (biopsy) is taken if these tests reveal an abnormal area. The aim of this project is to develop a blood test that can detect breast cancer cells, and also the type of breast cancer earlier than we can at present. Raman spectroscopy uses a laser to excite the chemical signals in a blood sample to create a fingerprint of that sample. If breast cancer features are present, the breast cancer fingerprint can then be analysed to provide information on treatment strategy. Ultimately, this technique would allow earlier diagnosis and may help patients to start treatment sooner than is possible currently. The addition of a cancer-specific test such as Raman to the urgent suspected breast cancer referral pathways could increase the probability of breast cancer being confirmed in patients who are referred to clinics. This could assist with more effective triage of patients to breast clinics, particularly with current levels of high demand.

Who can participate?
Women aged over 18 years old with a confirmed diagnosis of breast cancer and a control group of women with a benign outcome after assessment from a specialist breast triple assessment clinic

What does the study involve?
This study will recruit symptomatic patients who are referred to specialist breast services with suspicion of breast cancer. The study seeks to obtain blood samples for analysis using spectroscopy in vitro diagnostic devices. Outcomes from specialist breast clinics (cancer/normal assessment findings) will be used to train and test a machine learning algorithm to allow calculation of the sensitivity and specificity of the device.

What are the possible benefits and risks of participating?
This research will investigate if the cause of a breast lump (including cancer) can be diagnosed by a simple blood test. Early diagnosis before symptoms develop is vital for the best outcome. Current screening tests can be invasive and unpleasant, so alternative tests are needed. There is potential for patient benefit from this original research, which includes easier detection by a blood test and the ability to monitor response to treatment. There are small risks involved with taking a blood sample. These include bruising, bleeding, pain/discomfort and infection at the local site from which the blood is taken.

Health condition(s) or problem(s) studiedBreast cancer detection
InterventionThe study involves taking a blood test (approximately one tablespoon of blood) for analysis. Participants will be asked to participate in the study by signing and initialling a consent form. The blood test can then be collected by a researcher experienced in blood sampling. Participants will be required to fast before the blood test is taken (i.e. no food and only clear fluids for up to 4 hours before the blood test). There is no further action needed by participants. The results from the blood test will not affect clinical care as it is a research tool only.

The primary outcome will establish the performance of the Raman spectroscopy analysis system for the detection of breast neoplasia (1. Ductal carcinoma-in-situ and 2. Invasive carcinoma) in its intended population (symptomatic patients referred to tertiary breast services undergoing triple assessment) through outcome measures of test sensitivity and specificity.
Intervention typeNot Specified
Primary outcome measureTest sensitivity and specificity measured using outcomes from specialist breast clinics (cancer/normal assessment findings) to train and test a machine learning algorithm at one timepoint
Secondary outcome measures1. To determine an association between modes of presentation/symptomatology of breast cancer measured using Raman spectroscopy at one timepoint
2. To determine an association between breast cancer / pre-malignant conditions (DCIS) measured using Raman spectroscopy at one timepoint
Overall study start date01/08/2022
Completion date31/08/2024
