“…A number of studies have investigated different approaches to identify STAS in ADCs pre-and intraoperatively. 13,19,[28][29][30][31] To name just a few, Toyokawa et al reported that the presence of notch and the absence of ground-glass opacity (GGO) were associated significantly with STAS in ADCs. 29 13 Besides, it has been reported that intraoperative imprint cytology with the N-H classification for ADC was well correlated with the STAS status of the tumor.…”

“…However, the problem of multicollinearity leading to predictive model overfitting cannot be ignored. Jiang et al (25) found that the random forest model built with reliable radiomics features (intraclass correlation coefficients ≥0.75) could obtain a good predictive performance in spreading through the air space in lung adenocarcinoma. Traverso et al (26) proposed that machine learning-based radiomics methods may be useful for robust predictive model development.…”

“…Our results showed that the AUC of the nomogram model was slightly larger than that of the clinical model in both the training and test sets, but there were no statistically significant differences between the nomogram and clinical models in either the training set or test set (P = 0.2108 and 0.1324, respectively), which indicated that CT image features could provide plenty of information for making a preliminary judgment on the existence of STAS. Jiang et al developed a random forest model using CT-based radiomics features and achieved an AUC of 0.754 for predicting the existence of STAS [ 18 ]. Another study built a Naïve Bayes model using five radiomics features to predict STAS that showed good performance with an AUC of 0.63 in internal validation and an AUC of 0.69 in external validation [ 17 ].…”

“…Some studies on radiomics showed that radiomics features performed well for clinical decision making in patients with lung cancer [ 15 , 16 ]. To date, there have been two studies on the radiomics analysis of STAS, which predicted the existence of STAS by establishing different models [ 17 , 18 ]. Although the results showed that STAS could be predicted preoperatively, the methods and results of the two papers were not completely consistent.…”
