Brief Summary:
Intraoperative pathological diagnosis such as frozen section and imprint cytology is not routinely recommended in clinical practice because of time and accuracy concerns. Full-field optical coherence tomography (FF-OCT) is a new optical imaging technique that could generate sectioning tomogram from fresh tissue and provide close-to-pathology depiction of the morphological structure and pathological changes in minutes without conventional tissue preparation, slicing, and staining, and dynamic cell imaging (DCI) added the viability information of cells/tissue, which could be more important in cancer diagnosis. This study was to evaluate the feasibility and diagnostic value of FF-OCT and DCI in breast lesions and lymph node specimens during breast cancer surgery. We evaluated normal breast tissue, benign breast lesions, breast cancer and axillary lymph node specimens resected from patients undergoing breast surgery.

Condition or disease Intervention/treatment
Breast Neoplasms Diagnostic Test: Light-CT

Detailed Description:
Light-CT, a special-designed pathology-approximation system which is based on the lighting feature or dynamic feature of tissue and cells, is used to detect malignant cells or tissue in fresh specimens. Morphological structure and pathological changes could be captured in minutes, which implies a possible application in intraoperative diagnosis. In this study, fresh breast tissue, fat, benign breast lesions, breast cancer and axillary lymph node specimens are collected to assess the usefulness of Light-CT. During the in vitro examination, both FF-OCT and DCI images are obtained and stored. Imaging analysis would be performed in traditional imaging analysis like manner and an artificial intelligence aided approach as well.

Group/Cohort Intervention/treatment
All specimens are detected using Light-CT
Diagnostic Test: Light-CT
Fresh specimen is trimmed into a block with a size not larger than 2.5 cm (Typically not larger than 1.5 cm). Prepared specimen is submitted to Light-CT tests. FF-OCT images are obtained to depict the structure information and DCI images are generated to collect the dynamic information of the cell and tissue. After the imaging detection, specimens are submitted for routine pathological diagnosis to obtain corresponding pathological images.

Primary Outcome Measures :
  1. Sensitivity of Light-CT [ Time Frame: One week after the release of the pathological reports. ]
    The true positive rate measures the proportion of positives that are correctly identified by ultrasound

Secondary Outcome Measures :
  1. The lighting feature of different tissue [ Time Frame: Through study completion, an average of 1 year ]
    By the comparison analysis of FF-OCT and DCI images and corresponding pathological images, lighting feature would be extracted.

  2. Specificity of Light-CT [ Time Frame: One week after the release of the pathological reports. ]
    The true negative rate measures the proportion of positives that are correctly identified by Light-CT.

  3. Examination time [ Time Frame: Through study completion, an average of 1 year ]
    The time from the specimen preparation to the completion of the examination.
