Objective To observe the value of intratumoral and peritumoral CT radiomics combined with clinical features for preoperative predicting lymphovascular invasion(LVI)of early lung adenocarcinoma.Methods Totally 252 patients with stage Ⅰ-Ⅱa lung adenocarcinoma were retrospectively enrolled and were divided into positive group(n=63)and negative group(n=189)according to LVI or not,also into training set(n=201)and test set(n=51)at a ratio of 8∶2.Clinical data and CT findings being significantly different between groups were included in multivariate logistic regression analysis to screen independent predictors of early lung adenocarcinoma LVI and to construct CT-clinical model.The best radiomics features were extracted and screened in ROI of tumor(ROI1)and outward of 3(ROI2),5(ROI3)and 7 mm(ROI4)with automatic delineation and expanding algorithm,respectively.K-nearest neighbor(KNN),support vector machine(SVM),decision tree(DT),random forest(RF)and logistic regression(LR)algorithms were used to construct radiomics models.The best classifier algorithm and ROI which could provide more effective radiomics information were selected to construct the best radiomics model,which was used to construct the combined model combining with CT-clinical model.Receiver operating characteristic curves were drawn,and the areas under the curves(AUC)were calculated to evaluate the efficacy of the above models for preoperative predicting early lung adenocarcinoma LVI.Results Solid lesion and CT-N+stage were both independent risk factors for early lung adenocarcinoma LVI(both P＜0.05).Peritumor 5 mm volume(GTPV5)was obtained based on ROI3,and the best radiomics model was the model established based on 14 optimal radiomics feature selected from RFGTPV5.AUC of CT-clinical model,RFGPTV5 model and combined model for preoperative predicting early lung adenocarcinoma LVI was 0.875,0.908 and 0.917 in training set,while was 0.831,0.853 and 0.862 in test set,respectively.Conclusion Intratumoral and peritumoral CT radiomics combined with clinical features had good efficacy for preoperative predicting LVI of early lung adenocarcinoma.Intratumor and peritumor 5 mm ROI could provide more valuable information.

In recent years， enhanced recovery after surgery （ERAS） has been widely used in clinical practice， aiming to optimize perioperative management measures through evidence-based medicine and reduce the physical and mental trauma， stress reactions， and complications of surgical patients through multidisciplinary collaboration. This paper examined the clinical practice of ERAS from the perspective of medical humanities， reviewed its development and characteristics， and first pointed out that the concept of “minimal harm” laid the medical humanities foundation for ERAS. However， the concept of “minimum harm” faced ethical and realistic challenges in practice， such as differentiated cognition between benefits and non-harm， the tension between generalization and personalization， and the gap between rehabilitation continuity and family care. This paper led into the caregiving perspective of social sciences， proposed “optimal care” as a supplement to the medical humanities concept of ERAS， and introduced its connotation and practice. The combination of “minimal harm” and “optimal care” can provide theoretical guidance for medical humanistic care in ERAS and innovate the practical path of medical humanities into clinical practice.
