ABSTRACT

Objective:To evaluate the diagnostic performance of radiomics model based on contrast-enhanced ultrasound(CEUS) in predicting pathological complete response(pCR) after neoadjuvant chemoradiotherapy(nCRT) in patients with locally advanced rectal cancer(LARC).Methods:One hundred and six patients with LARC who underwent total mesorectal excision after nCRT between April 2018 and April 2023 in the First Affiliated Hospital of Guangxi Medical University were retrospectively included, the patients were randomly divided into a training set of 63(14 pCR patients) and a validation set of 43(12 pCR patients) in a 6∶4 ratios. Radiomics features were extracted from the tumors′ region of interest of CEUS images based on PyRadiomics. Intra-class correlation coefficient(ICC), Mann-Whitney U test, and least absolute shrinkage and selection operator(LASSO) algorithms were used to reduce features dimension. Finally, 7 radiomics features relevanted to pCR were selected to construct an ultrasomics model using elastic network regression, based on the R language. A combined model was constructed by jointing clinical feature. The performance of the models was assessed with the area under the ROC curve(AUC). Results:The AUC of the ultrasomics model and the combined model was 0.695(95% CI=0.532-0.859) and 0.726(95% CI=0.584-0.868) respectively in the training set. The AUC of the ultrasomics model and the combined model was 0.763(95% CI=0.625-0.902) and 0.790(95% CI=0.653-0.928) respectively in the validation set. Both univariate and multivariate Logistic regression analyses showed that CA199( P<0.05) and ultrasomics score( P<0.001) could be an independent predictor of pCR after nCRT in patients with LARC. Conclusions:The CEUS-based radiomics scores has certain predictive value for whether LARC patients achieve pCR after nCRT, and may provide a non-invasive imaging biomarker for predicting LARC patients achieve pCR after nCRT.

ABSTRACT

Objective To explore the difference between interval storage and continuous storage of dynamic imagines in contrast enhanced ultrasound (CEUS) quantitative analysis. Methods Two CEUS were performed for each of fifteen participants using interval storage and continuous storage of dynamic images. A number of parameters were analyzed including rising time (RT), time to peak (TTP), mean transit time (MTT), maximum intensity (IMAX), and area under the curve (AUC). The disk usage and time consumpation were also compared for analysis. Results There were no differences in RT, TTP, MTT, IMAX, AUC between the two groups (t=1.028, 1.012, 0.558, 0.223, 0.556, P=0.322, 0.329, 0.586, 0.826, 0.587). There was significantly positive correlations between them (r=0.989, 0.992, 0.867, 0.865, 0.947, all P<0.05). The disk usage in interval storage group was about 1/3 of that in contiunous storage group. And the interval storage method could saved 25-30 min in each case. Conclusion Interval storage is worthy for further clinical application on the groud of its disk usage sparing and less time consumpation without compromising the image quality for analysis.

ABSTRACT

To investigate the expression of ICAM 1 in peripheral blood lymphocyte in elderly patients suffering from lung cancer and the effect of chemotherapy on the expression of ICAM 1, peripheral blood ICAM 1 contents in 52 elderly patients with lung cancer were assayed with the method of immune flow cytometry before and after chemotherapy, and 32 normal elders and 35 patients with benign disease in lung served as controls. The results showed that the expression of ICAM 1 on lymphocyte in elders with lung cancer was significantly higher than that in patients with benign disease and normal controls. There was a significant difference between ICAM 1 expression in patients in stage Ⅲ, Ⅳ and that in patients in stage Ⅰ and Ⅱ. ICAM 1 in peripheral blood before chemotherapy was significantly higher than that after chemotherapy. It is suggested that the expression of ICAM 1 in peripheral blood lymphocyte might be useful to judge the efficacy of chemotherapy and evaluate prognosis in geriatric patients with lung cancer.

ABSTRACT

Confocal microscope and flow cytometry were used to study the adhesion and the expression of adhesive molecules between different metastatic lung cancer cells and endothelial cells (EC) in vitro. Tea polyphenols (TP) were tested for their effect on tumor cell endothelial adhesion.The results showed that the adhesion and expression of CD44?CD54 were significantly higher in PG cells than those in D9 cells. Treatment of EC monolayers with LPS(0 5ug/ml) for six hours caused an increase in adhesion of PG to EC and adhesive molecules expression. TP could inhibit the adhesion of PG to EC and expressions of CD44 and CD54 in dose dependent manner. It suggested that adhesion molecules might play an important role in mediating the adhesion of lung carcinoma to EC and hematogenous metastasis; TP had an inhibitory effect on metastasis of lung cancer.
