Pancreatic cancer is a highly virulent malignancy associated with a high mortality rate. The rapid on-site evaluation (ROSE) method can expedite the diagnostic process for pancreatic cancer by enabling the immediate analysis of fast-stained cytopathological images with on-site pathologists. However, the widespread implementation of ROSE diagnosis has been impeded by the shortage of pathologists. Deep learning offers the prospect of automating the classification of ROSE images for diagnostic purposes. Nonetheless, it poses a challenge to accurately model the complex local and global image features. The conventional convolutional neural network (CNN) structure is proficient in extracting spatial features, yet it tends to overlook global features when prominent local features are misleading with bias. Conversely, the Transformer structure excels at capturing global features and long-range relationships, but has limited capacity to incorporate local features. To address this challenge, we propose a multi-stage hybrid Transformer (MSHT) that leverages the strengths of both methods by using spatial attention to enhance global understanding. The MSHT features a CNN backbone that extracts multi-stage local features at different scales to serve as attention guidance, while the Transformer encodes these features during its sophisticated global modeling. The MSHT achieves high accuracy and promising interpretability in the classification of cancerous and normal pancreatic cells in ROSE samples. The superior results obtained by MSHT compared to state-of-the-art models make it a possible approach for general cytopathological image analysis. This highlights the potential for AI-based computer-aided diagnosis (CAD) systems to boost the diagnostic process and alleviate the demand for on-site pathologists. The application of such systems can benefit broader populations where on-site pathologists are scarce.
