Personalized Prediction of Postoperative Recurrence in Lung Squamous Cell Carcinoma: Integrating AI-Based Nuclear Morphometry and Clinical Data
This study leverages AI to analyze quantitative nuclear morphological features from digital pathology images to predict postoperative recurrence in lung squamous cell carcinoma (LSQCC) patients. By integrating AI-extracted morphological features with clinical information, the research aims to develop a prediction model for personalized postoperative management. The methodology involves manual selection of regions of interest (ROIs), nuclear extraction and segmentation, and quantification of morphological and intranuclear texture features using CellProfiler and CFLCM. SVM and Random Forest algorithms are applied to create six recurrence prediction models (2-year, 5-year, and 3-category), which are then combined into an AI-based risk score. This score is further integrated with pathologic stage to create a 'total risk score'. All six AI models demonstrated stable predictive performance (AUC 0.76-0.91), and Kaplan–Meier analysis showed that the total risk score provided precise risk stratification (p < 0.005). The findings suggest that integrating AI-based nuclear morphology and clinical data offers an objective and practical tool for tailored clinical decision-making in LSQCC postoperative management.

AI-Powered Nuclear Morphometry for LSQCC Recurrence
This study introduces an AI-driven approach to predict postoperative recurrence in Lung Squamous Cell Carcinoma (LSQCC) by analyzing quantitative nuclear morphological features from digital pathology images. It aims to personalize postoperative management by integrating these AI-extracted features with traditional clinical information, providing a more precise risk assessment beyond standard pathological staging.
Robust Predictive Model Development
Three recurrence models (2-year, 5-year, and 3-category) were developed using Support Vector Machine (SVM) and Random Forest (RF) algorithms, resulting in six distinct predictive models. These models demonstrated robust performance, with Area Under the Curve (AUC) values ranging from 0.76 to 0.91, indicating strong predictive ability for postoperative recurrence in LSQCC.
Enhanced Risk Stratification with Total Risk Score
An innovative 'total risk score' was developed by integrating the AI-based risk score (derived from the ensemble of six models) with the pathologic stage. Kaplan–Meier analysis revealed that this combined total risk score provided superior and more precise risk stratification (p < 0.005) compared to using the AI-based risk score or pathologic stage alone, enabling clearer separation between high- and low-risk groups.
Enterprise Process Flow: AI-Driven Morphometric Feature Extraction
The process begins with whole-slide imaging (WSI) at 20x magnification. Regions of interest (ROIs) are manually selected and non-tumor components are masked. Nuclear extraction and segmentation are performed using ilastik and pix2pix, respectively. Finally, CellProfiler quantifies 90 morphological and intranuclear texture features per nucleus, which are then used to calculate 960 ROI-based features via CFLCM.

Key Nuclear Features for Prediction
The study identified distinct key nuclear features driving predictions in different AI models. SVM models predominantly leveraged nuclear shape-related features, with nuclear orientation heterogeneity being critical. In contrast, Random Forest models showed a more balanced use of both shape-related and intranuclear texture features, highlighting intranuclear texture contrast as significant.
