Preprints with The Lancet is a collaboration between The Lancet Group of journals and SSRN to facilitate the open sharing of preprints for early engagement, community comment, and collaboration. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These preprints are early-stage research papers that have not been peer-reviewed. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied.

Background: Difficulty diagnoses of leptomeningeal metastasis and lack of typical symptoms are considerable challenges in the clinical. As CSF a gold standard in LM, it is necessary to establish a deep learning model to classify cancer cells in CSF to facility doctor early diagnosis.
Method: CNN models based on ResNet-Inception-V2 or ResNet-50 are used to training cells in CSF, which is evaluated by average precision or accuracy. Besides, our research comprised the interpretation of 42 doctors with different experience and CNN in the human-machine test to validate CNN's performance.
Results: The precision of cancer cells was over 95% in the CNN1 model. In the human-machine test, the cell classification model's(CNN1) accuracy was close to experts and higher than other doctors. The cancer cell classification model's accuracy (CNN2) is 10% higher than that of experts, and the time-consuming is only 1/3 of that of an expert. We successfully achieved cell training in the small cell dataset in an 8-way cell classification model(CNN3), which overall accuracy is 90%.
Explanation: Deep learning can be widely used cerebrospinal fluid cytology pictures for classification. For difficult cancer classify task, CNN accuracy is higher than that of specialist doctors, and its performance is better than that of junior doctors and intern.
