ABSTRACT
Objective:To develop and validate a nomogram model for predicting radiation-induced pneumonitis in esophageal cancer based on CBCT radiomics characteristics combined with clinical characteristics and lung dosimetric parameters.Methods:Clinical data, dosimetric parameters and CBCT images of 96 patients with thoracic middle esophageal squamous cell carcinoma treated by intensity-modulated radiation therapy (IMRT) from 2017 to 2019 were analyzed retrospectively. The CBCT images of each patient in three different time periods were obtained. All patients were assigned randomly into the primary cohort ( n=67) and validation cohort ( n=29). Double lungs were selected as the region of interest (ROI), and 3D-slicer software was used for image segmentation and feature extraction. The LASSO regression were applied to identify candidate radiomic features and construct the Rad-score. The optimal time period, clinical and dosimetric parameters were selected to construct the nomogram model, and then the area under the receiver operating characteristic curve (AUC) was used to evaluate the prediction effect of the model. Results:The predictive capacity of the model in the first time period was the highest. In the primary cohort, the AUC was 0.700(95% CI: 0.568-0.832), the sensitivity was 61.5%, and the specificity was 75.0%. In the validation cohort, the AUC was 0.765(95% CI: 0.588-0.941), the sensitivity was 84.6% and the specificity was 64.7%, respectively. In the combined nomogram model, the AUC in the primary cohort was 0.836(95% CI: 0.700-0.918), the sensitivity was 96.0% and the specificity was 54.8%. In the validation cohort, the AUC was 0.905(95% CI: 0.799-1.000), the sensitivity was 92.9% and the specificity was 73.3%, respectively. The diagnostic efficiency of combined nomogram model was the best. Conclusions:The nomogram model based on early lung CBCT radiomics has certain predictive efficiency for RP. The model of lung CBCT radiomics in early stage of radiotherapy can predict RP of esophageal cancer. The nomogram model based on Rad-score combined with V 5Gy, MLD and tumor stage yields better predictive accuracy, which can be used as a quantitative prediction model for RP.
ABSTRACT
Objective:To investigate the effectiveness of abdominal compression in tumor motion and the target volume, and analyze the suitable margins of planning target volume (PTV) for patients treated with lung-SBRT based on 4DCT.Methods:Patients diagnosed with peripheral pulmonary tumor were enrolled. The patients were divided into the whole group, upper-middle-lobe group (group A) and the lower-lobe group (group B). Each patient underwent 3DCT, 4DCT with abdominal compression (4DCT com) and 4DCT with free breath (4DCT free) scans. The GTVs were delineated and IGTVs on these images. PTV MIP 5 mm, PTV MIP 4 mm, PTV MIP 3 mm were constructed with a 5, 4, 3 mm margin in left-right (LR), anterior-posterior (AP) directions and cranial-caudal (CC) directions. Results:The median motion vector with compression reduced by 30.92% in whole group, increased by 3.42% in group A and reduced by 18.80% in group B, respectively. And there were no significant differences of TMA LR, TMA AP, TMA CC and motion vector by the Wilcoxon test ( P>0.05). The median sizes of IGTV MIP com , IGTV MIP free and IGTV10 com, IGTV10 free were 4.01, 5.36 cm 3and 6.59, 7.65 cm 3, with statistically significant difference ( Z=-3.45, -3.14, P<0.01). The median ratio of DI of IGTV CBCT com in PTV MIP 5 mm, PTV MIP 4 mm and PTV MIP 3 mm≥95% was 100%, 100% and 83.33%, respectively. Conclusions:The patients′ respiratory pattern changed with abdominal compression and abdominal compression is useful in reducing the size of IGTV MIP and IGTV10, which could reduce the target volume and protect the normal tissue. Adding a 4 mm margin to IGTV MIP com based on 4DCT account for respiration in SBRT is a tendency for precise radiotherapy.
ABSTRACT
Objective:To investigate the effects of clinical characteristics, irradiation techniques and dose-volume parameters on radiation pneumonitis(RP) in thoracic segment esophageal cancer patients, so as to provide reference for the formulation of radiotherapy protocol for thoracic esophageal cancer.Methods:The incidence of RP in 247 patients with thoracic segment esophageal cancer from June 2014 to June 2019 was analyzed retrospectively, then univariate and multivariate analyses were performed on the clinical characteristics, radiation techniques and lung dosimetry parameters of these patients. The area under receiver operating characteristic (ROC) curve was used to verify the diagnostic efficacy of RP≥grade 1, ≥grade 2 and ≥grade 3.Results:There were 118 cases (47.8%)with RP≥grade 1, 54 cases (21.9%)with RP≥grade 2, 17 cases (6.9%)with RP≥grade 3. The result of univariate analysis showed that lung V5- V40 and MLD were both related to the occurrence of RP≥grade 1( Z=-5.802 to -4.306, P<0.05). ≥grade 2, and≥grade 3, respectively( F=0.057 to 11.616、0.087 to 3.392, P<0.05). GTV volume, PTV volume, GTV/lung volume(%) and PTV/lung volume(%) were related to RP≥grade 1( Z=-3.377 to -2.041, P<0.05)and RP≥grade 2( F=3.600 to 9.801, P<0.05). Smoking index >400 was significantly correlated with RP≥grade 3( χ2=13.295, P<0.05), and chronic obstructive pulmonary disease (COPD) was significantly correlated with RP≥grade 1( χ2=9.146, P<0.05). However, there was no significant correlation between RP and different irradiation techniques, chemotherapy factors, radiotherapy dose, esophageal cancer stage and cancer location.The result of multivariate analysis showed that V5 and V40 were independent risk factors of RP≥grade 1(AUC 55.74%、4.13%)、MLD was independent risk factors of RP≥grade 2 (AUC 11.91 Gy), and V5 was independent risk factors of RP≥grade 3(AUC 57.60%). The smoking index>400 was the independent risk factor of RP≥grade 3 ( Wald=5.964, P<0.05), and COPD was the independent risk factor of RP≥1 grade ( Wald=6.110, P<0.05). Conclusions:The incidence of RP is low after radiotherapy for thoracic segment esophageal cancer. The dosimetric parameters such as lung V5, V40, MLD, smoking degree, COPD and other clinical characteristics are closely related to the occurrence of RP of corresponding grades.

ABSTRACT
Epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) is a kind of targeted drug for the treatment of non-small cell lung cancer (NSCLC),but almost all patients develop EGFR-TKI resistance.In Chinese medicine,it is believed that Yang deficiency is the leading cause of tumor,which could end up with the internal formation of cancer toxin and promote the formation of tangible excess pathogens.Clinical and experimental studies have shown that the Chinese medicine treatment based on Yang-warming method can inhibit EGFR-TKI resistance and improve the therapeutic effect of EGFR-TKI.The mechanism may be related to the regulation of miRNA gene and estrogen receptor expression,being against tumor heterogeneity and the regulation of tumor microenvironment.Therefore,Yang deficiency is the key pathogenesis of the EGFR-TKI resistance in NSCLC,and the method reinforcing Yang and suppressing Yin is the basic therapeutic way in Chinese medicine to overcome EGFR-TKI resistance.
ABSTRACT
Objective To investigate the practice status of the newNursing practice standards for intravenous therapy in secondary and above hospitals in Shandong province. Methods Self-designed questionnaire was used to investigate 3051 nurses from 129 hospitals in 17 cities in Shandong province. Results Nurses′ awareness rate of the new Nursing practice standards for intravenous therapy was 92.69%(2828/3051);92.13%(2811/3051) nurses reported that their hospitals used the new standard, 65.78%(2007/3051) nurses reported that their hospitals had applied the standard since the second half of 2014; 92.92% (2835/3051) nurses reported that their hospitals had revised their practice rules according to the new standard;93.54%(2854/3051) nurses reported that their hospitals had revised the related nursing process; 50.08% (1528/3051) nurses thought the new standard helpful to clinical practice;22.98%(701/3051) nurses knew well about the new standard;53.85%(1643/3051) nurses thought the standard applicable to clinical practice. Conclusions As nurses do not master the Nursing practice standards for intravenous therapy well, they need strengthened training. Hospitals should fresh their rules, protocolsand supply training program to improve nurses′ knowledge and skill. Meanwhile, Nursing practice standards for intravenous therapyalso needs to be revised and improved according to nurses feedback.
