Diagnostic Efficiency of Artificial Intelligence for Surgical Neuropathology
Study Details
Study Description
Brief Summary
This is a multi-center, prospective, self-controlled, diagnostic accuracy comparative study of Artificial Intelligence Diagnostic System for Surgical Neuropathology. The investigators will compare the diagnostic efficiency of Artificial Intelligence with that of practicing pathologists, and suppose that the diagnostic efficiency of artificial intelligence in prospective clinical data is no less than that of pathologists.

Detailed Description
In this study, 141 patients will be recruited. After being enrolled, the patients will accept surgery and specimens for pathological analysis will be taken according to the routine treatment process.
The histopathologic slides will then be digitized by a whole-slide scanner. The images will be reviewed by gold standard committee for evaluation of ground truth. And then be separately diagnosed by Artificial Intelligence Diagnostic System and practicing pathologists. So the investigators can compare the diagnostic efficiency of Artificial Intelligence with that of pathologists, thus understand the gap between artificial intelligence and actual clinical practice.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Artificial Intelligence A deep learning based artificial intelligence diagnostic system(DOI:10.1093/neuonc/noaa163) |
Diagnostic Test: Artificial Intelligence
The investigators will use the Artificial Intelligence Diagnostic System to review the H&E stained slide of each patient and then report the classification of the tumor on a 10-type scale.
|
Active Comparator: Practicing Pathologists One pathologist who has at least 5 years of experience |
Diagnostic Test: Practicing Pathologists
The ordinary pathologist will review the H&E stained slide of each patient(without additional informations such as: Immunohistochemistry et al.) and then report the classification of the tumor on a 10-type scale only bases on the slide images
|
Other: Gold Standard A committee composed of two expert pathologists who has at least 10 years of experience and one expert pathologist who has at least 15 years of experience |
Diagnostic Test: Gold Standard
Firstly, the two expert pathologist(>=10 years of experience) will review the H&E stained slide of each patient on their own (with additional informations such as: Immunohistochemistry et al.) and then report the classification of the tumor on a 10-type scale.If they report the same opinion, that opinion will perform as the ground truth; while if their opinion clash with each other, the expert pathologist(>=15 years of experience) will get involved and the agreement of three experts will perform as the ground truth

Outcome Measures
Primary Outcome Measures
- Diagnostic Accuracy of Study Arms [1 week after the last patient's diagnosis is completed]
The number of correctly diagnosed participants by study arms divided by the total number of participants
Secondary Outcome Measures
- Sensitivity and specificity of Study Arms [1 week after the last patient's diagnosis is completed]
Sensitivity and specificity of study arms for each type calculated by 2x2 tables
- Spearman Coefficient of Study Arms related to Gold Standard [1 week after the last patient's diagnosis is completed]
Spearman Correlation Analysis between Study Arms and Gold Standard
