Rapid histology of core needle biopsies is essential to ensure the precise FT for localized lesions and to determine tumor grades. However, it is difficult to achieve both high accuracy and speed with currently available histopathology methods. Here, we demonstrated that stimulated Raman scattering (SRS) microscopy could reveal the largely heterogeneous histologic features of fresh prostatic biopsy tissues in a label-free and near real-time manner. A diagnostic convolutional neural network(CNN) built based on images from61 patients could classify Gleason patterns of prostate cancer with an accuracy of 85.7% . An additional 22 independent cases introduced  \nas external test dataset validated the CNN performance with 84.4% accuracy. Gleason scores of core needle biopsies from 21 cases were calculated using the deep learning SRS system and showed a 71% diagnostic consistency with grading from three pathologists. This study demonstrates the potential of a deep learning–assisted SRS platform in evaluating the tumor grade of prostate cancer, which could help simplify the diagnostic workflow and provide timely histopathology compatible with FT treatment.  \nSignificance: A platform combining stimulated Raman scattering microscopy and a convolutional neural network provides rapid histopathology and automated Gleason scoring on fresh prostate core needle biopsies without complex tissue processing.  \nIntroduction  \nProstate cancer is the second most diagnosed cancer and the fifth leading cause of cancer-related deaths among men worldwide (1) . Over the past decades, focal therapy (FT) has been an emerging novel option for selected patients with clinically localized cancer like prostate cancer, aiming to eradicate the targeted lesion while preserving the surrounding key functional structures(2–5)However, many urologists are concerned that FT could fail in cancer control for the inability of imaging biopsy to detect multifocal lesions in prostate cancer and the inaccuracy of tumor location during operation (3) . The main concern was derived from the incomplete tumor ablation due to the lack of real-time intraoperative pathologic guidance. The conventional intraoperative frozen section–based workflow requires highly effective cooperation during tissue transport and slide processing, which is not  \n1State Key Laboratory of Surface Physics and Department of Physics, Human Phenome Institute, Academy for Engineering and Technology, Key Laboratory of Micro and Nano Photonic Structures (Ministry of Education), Yiwu Research Institute of Fudan University, Fudan University, Shanghai, P.
