简要总结
Through this project, the rapid staining process will be optimized for ex-vivo human lung specimens and integrate advanced ex-vivo mesoscale nonlinear optical gigascope. Initially, this will provide rapid digital pathological diagnosis during lung cancer surgeries. This will help achieve the dual goals of precise and efficient complete resection of lung cancer tissues while preserving tissue functionality. The application of this technology aims to provide higher-quality medical services for patients suffered from lung cancers.
详细描述
Frozen section can provide rapid diagnosis during the operation, and its information is very important for surgeons to make decisions for the operative methods, especially for patients whose clinical conditions or lesions sites are inappropriate for biopsy. The frozen section procedure requires a pathological laboratory, a skilled technician, and an experienced pathologist. Not all pathological laboratories can perform the frozen section procedure. The frozen section can also cause frozen artifacts and tissue loss especially for small biopsy samples. In this study rapid fresh digital pathology combining the rapid whole-mount hematoxylin-eosin (H&E) tissue staining (the-RTS) method and optical imaging via mesoscale nonlinear optical gigascope (mNLOG) will be used to obtain digital images with ultra-high resolution of resected lung specimens. These images will be analyzed by experienced pathologists and compared with H&E-stained slides from traditional frozen section procedures to see if the rapid fresh digital pathology can be used as an alternative method for intraoperative frozen section procedure.
Moreover, the potential to use rapid fresh digital pathology in the detection of lung cancer biomarkers (including low-grade or high-grade patterns, invasive or in situ lesions, and STAS) and three-dimensional pathology will also be evaluated.

时间窗: 1 years
Obtain a portion of specimens and directly perform rapid H\&E staining. Then, place the edge of the cut surface of the specimen flat on the microscope objective for observation. The same specimen will then undergo the standard histological staining process in the pathology department for comparative analysis. Another portion of the specimen will be processed using the pathology department's standard frozen section procedure for comparative analysis. In this study, the investigators will acquire the pathological tissue images (with multiple distinct structures like nuclear atypia, vessels, vesicles, and so on) in those images via rapid-fresh-pathology, frozen pathology and formalin-fixed embedded pathology. And the analysis of the number of abnormal cells, irregular vesicles and tumor structures will be conducted to provide pathologists information to compare and distinguish whether it is normal or not.
