Patient who had breast ultrasound done and classified according to the BI-RADS US classification, and the result was in category 4 or 5.

Patient with indications for biopsy unless breast biopsy was performed in the last 3 months (except for FNA). Thermography examination was performed with the use of Braster device.

Patient undergo contact thermography examination with the use of liquid crystal contact thermography device- Braster.

Thermographic breast examination performed by Braster device

The study was a multicentre, observational, cross-sectional, open and monitored trial involving 274 females who were subject to an examination using liquid crystal contact thermography device as a complementary tool to standard diagnostic imaging procedures of the breast glands. The study was conducted in specialist outpatient clinics. Patients were eligible to participate in the study upon signing the informed consent form. There was no follow up after the thermographic examination.

The study will comprise of a single registration of thermographic images of the breasts which will be subjected to automatic and expert analysis by radiologists.

Women aged 18-49 who had breast ultrasound performed with a result of BI-RADS 4b, 4c or 5. Thermography examination was performed with the use of contact thermographic breast examination device as a complementary tool to breast ultrasound. The planned number of participants in the group: n=700 people.

Women aged 50 and above who had mammography and/or breast ultrasound performed (both examinations are obligatory, i.e. if the subject was recruited based on mammography, then ultrasound must be performed and vice-versa). Women were recruited if they had a result of BI-RADS 4, 4a, 4b, 4c or 5 on mammography or BI-RADS 4a, 4b, 4c or 5 on ultrasound. Thermography examination was performed with the use of contact thermographic breast examination device as a complementary tool to the aforementioned techniques. The planned number of participants in the group: n=2100 people.

Subgroup C1 (n=100 people): women aged 18-49 years, who underwent breast ultrasound with a result of BI-RADS 1 or 2.

Sub-group C2 (n=100 people): women aged 50 and above, who had mammography or breast ultrasound performed; with a result of BI-RADS 1 or 2 (both examinations are obligatory, i.e. if the subject was recruited based on mammography, then ultrasound must be performed and vice-versa).

Thermography examination was performed with the use of contact thermographic breast examination device as a complementary tool to the aforementioned techniques.

A class 2a medical device being an active non-invasive multiple-use thermographic contact tester that uses a technology of passive liquid crystal matrices placed in the head of the device that records a thermographic image of breast glands with application of these matrices to the examined organ. The examination is non-invasive.

The study is designed to evaluate the effectiveness of liquid crystal contact thermography in detecting pathological changes in female breasts compared to standard diagnostic methods.

The study is a multicentre, observational, cross-sectional, open and monitored trial involving approx. 3000 females who will be subject to an examination using liquid crystal contact thermography device as a complementary tool to standard diagnostic imaging procedures of the breast glands. The study is conducted in specialist outpatient clinics. Patients are eligible to participate in the study upon signing the informed consent form. There is no follow up after the thermographic examination.

The study will comprise of a single registration of thermographic images of the breasts which will be subjected to automatic and expert analysis by radiologists.

Primary objective of the study is to determine and compare the diagnostic efficacy of breast thermography using a medical device based on liquid crystal contact thermography to standard of care.

The subjects were divided into three groups based on age and Breast Imaging Reporting and Data System (BI-RADS). Thermography was performed as a complementary modality to standard of care. In group A, the investigators recruited women aged 18-49, who has a breast ultrasound performed and a result of BI-RADS 4b, 4c or 5. In group B, the investigators recruited women over 50 years of age with either a result of BI-RADS 4, 4a, 4b, 4c or 5 on mammography or BI-RADS 4a, 4b, 4c or 5 on ultrasound. If a positive result was present on one of these examinations, the other examination needed to be performed. Lastly, in group C, the investigators recruited women aged 18 and above with a BI-RADS score of 1 or 2 on mammography and/or breast ultrasound.

Predicted duration of the study is approximately 24 months.

Effectiveness of Liquid Crystal Contact Thermography in Detecting Pathological Changes in Female Breasts

Investigation of the Effectiveness of Liquid Crystal Contact Thermography in Detecting Pathological Changes in Female Breasts Compared to Standard Diagnostic Methods of Breast Cancer

The outcome is measured as number of subjects with pathological diagnosis of cancer. Subjects will be analysed based on age, 18-49 and women over 50.

Comparison of the field below the Receiver Operating Characteristic (ROC) curve (C statistic) and sensitivity and specificity between the age and recruitment groups as well as between the manual algorithm and automatic interpretation algorithm will take place with the use of Wald and McNemar tests.

Values P \< 0.05 will be recognised as statistically significant.
