Objective:To investigate the predictive value of nutritional risk related indicators in the prognosis of elderly esophageal squamous cell carcinoma (ESCC) patients undergoing radical radiotherapy.Methods:A retrospective case series study was conducted. The clinical data of ESCC patients aged ≥ 70 years who received radical radiotherapy in Shanxi Province Cancer Hospital from January 2015 to December 2019 were retrospectively analyzed. According to the radiotherapy planning system, the maximum transverse diameter of gross tumor volume of primary tumors (GTVt) and GTVt volume in the esophagus were calculated. The nutritional risk related indicators of ESCC patients before and after radiotherapy were calculated and recorded, including body mass index (BMI), geriatric nutritional risk index (GNRI), and neutrophil-to-lymphocyte ratio (NLR); Kaplan-Meier method was used for survival analysis, and log- rank test was performed; Cox proportional risk model was used to analyze the factors influencing the prognosis of patients. The overall survival (OS), progression-free survival (PFS), short-term efficacy, and adverse reactions of patients with different clinicopathological characteristics were compared.Results:The last follow-up time was 30 December, 2023. The 1-year, 3-year, and 5-year OS rates of 161 elderly patients with ESCC were 79.5%, 33.9%, and 16.1% respectively, with a median OS time of 25.8 months (95% CI: 20.11-31.49 months); the 1-year, 3-year, and 5-year PFS rates were 65.8%, 28.9%, and 14.8%, respectively, with a median PFS time of 20.0 months (95% CI: 16.31-23.69 months). There were statistically significant differences in the median OS time of patients with different age, lesion contrast length, maximum transverse diameter of GTVt, GTVt volume, short-term efficacy, BMI before radiotherapy, BMI after radiotherapy, GNRI after radiotherapy, NLR before radiotherapy, and NLR after radiotherapy (all P < 0.05); there were statistically significant differences in the median PFS time of ESCC patients with different age, maximum transverse diameter of GTVt, GTVt volume, short-term efficacy, BMI before radiotherapy, BMI after radiotherapy, GNRI after radiotherapy, and NLR before radiotherapy (all P <0.05). The results of multivariate Cox regression analysis showed that the maximum transverse diameter of GTVt was an independent influencing factor of the patients' OS ( P < 0.05); GTVt volume, short-term efficacy, GNRI after radiotherapy, and NLR before radiotherapy were independent influencing factors for OS and PFS of the patients (all P < 0.05). Among 161 elderly patients with ESCC, 45 achieved complete remission (CR), 111 achieved partial remission (PR), and 5 achieved stable disease (SD). There were statistically significant differences in the proportions of patients with different maximum transverse diameter of GTVt, GTVt volume, BMI after radiotherapy, GNRI after radiotherapy, and NLR before radiotherapy reaching CR and PR+SD (all P < 0.05). Among the 161 patients, grade 0, 1, 2, and 3 radiation-induced esophagitis (RE) occurred in 59, 54, 42, and 6 cases, respectively during treatment and within 3 months after treatment; among them, ≥ grade 2 RE occurred in 48 cases (29.8%); grade 0, 1, 2, and 3 radiation pneumonitis (RP) occurred in 95, 38, 25, and 3 cases, respectively; among them, ≥ grade 2 RP occurred in 28 cases (17.4%). Conclusions:Nutritional risk related indexes GNRI and NLR may be predictive indicators for the prognosis of elderly ESCC patients undergoing radical radiotherapy.

Objective:To detect the abnormal changes of myocardial blood perfusion in patients with hypertrophic cardiomyopathy (HCM) by myocardial contrast echocardiography(MCE) combined with exercise stress test.Methods:Twenty-seven patients with clinically diagnozed of asymmetric HCM in Fuwai Central China Cardiovascular Hospital from May 2020 to April 2021 were selected as the HCM group, and 29 healthy subjects during the same period were selected as the control group. All patients underwent routine echocardiography, resting and exercise stress MCE. The myocardial perfusion parameters of each segment of interventricular septum in the 2 groups were quantitatively analyzed: the peak plateau intensity (A value), ascending slope of the curve(β value) and value of A×β. According to the end-diastolic myocardial thickness, the interventricular septum of the HCM group was divided into hypertrophic and non-hypertrophic segments, and the myocardial contrast parameters of the interventricular septum of the study group were compared with those of the control group. The myocardial blood flow reserve value of the two groups were calculated, and the correlation of myocardial blood flow reserve value with left ventricular mass index (LVMI) and left ventricular remodeling index (LVRI) were analyzed.Results:No matter at rest or under stress, the A value, β value and A×β value of ventricular septal hypertrophic and non-hypertrophic segments in the hypertrophic cardiomyopathy group were lower than those in the control group, and the differences were statistically significant (all P<0.05). Under stress, the A value, β value and A×β value of interventricular septal hypertrophic segments were lower than those in non-hypertrophic segments in the HCM group, and the differences were statistically significant (all P<0.05). The myocardial blood flow reserve in the HCM group was negatively correlated with LVMI and LVRI( r=-0.899, -0.676; all P<0.001). Conclusions:In patients with HCM under resting and exercise stress, microcirculation disorders were found in both hypertrophic and non-hypertrophic segments of the ventricular wall, and the myocardial blood flow reserve was negatively correlated with LVMI and LVRI.

Objective:To explore the clinical value of adenosine stress myocardial contrast echocardiography in detecting myocardial blood perfusion abnormalities in patients with type 2 diabetes mellitus.Methods:Twenty-six patients with type 2 diabetes mellitus clinically diagnosed from May 2019 to January 2020 in the endocrinology department of Fuwai Central China Cardiovascular Hospital and 28 healthy examinees with gender and age matched during the same period were enrolled. Routine echocardiography, rest and adenosine stress myocardial contrast echocardiography were performed, the plateau signal intensity(A value), curve rising slope(K value) and A×K value of the myocardial perfusion time-intensity curve were obtained by offline analysis. And general data such as age, gender, disease course, body mass index and glycated hemoglobin were collected, and results of the two groups were compared statistically.Results:In the rest state, the A value of the myocardial perfusion parameter in the diabetic group was not significantly different from that of the control group, both in whole and in segments ( P>0.05), while the K value and A×K value of the myocardial perfusion parameters in the diabetic group were significantly lower than those in the control group ( P<0.05). In the stress state, the A value, K value and A×K value of myocardial perfusion parameters in the diabetic group were significantly lower than those in the control group, both in whole and in segments ( P<0.05). The detection rate of myocardial perfusion abnormality in the stress state was significantly higher than that in the rest state, and the difference was statistically significant ( P<0.05). The myocardial blood flow reserve in the diabetic group was negatively correlated with the course of disease and the level of glycated hemoglobin ( r=-0.580, P=0.020; r=-0.481, P=0.013). Conclusions:Adenosine stress myocardial contrast echocardiography can be used for detection of left ventricular myocardial perfusion abnormalities in patients with type 2 diabetes mellitus, which has great clinical application value.

Objective The aim of this study is to build a risk prediction model for the recurrence and metastasis of thoracic esophageal squamous cell carcinoma after radical surgery,and to analyze the factors affecting the disease free survival (DFS).Methods Conducted analysis of 1 191 patients with thoracic esophageal squamous cell carcinoma,who received radical resection from January 2007 to December 2011.The VaR boundary value of the risk prediction model was obtained by receiver operating characteristic (ROC) curve,and the boundary value was verified.The factors that affected DFS were analyzed by univariate analysis and Cox multiple factor prognosis analysis.Results There were 472 cases had recurrence and metastasis after treatment.There was a significant difference in VaR between patients with and without failure (t =-5.307,P ≤ 0.001).The VaR boundary value was 0.30 according to ROC curve analysis.The recurrence rate of the patients in the VaR ≤ 0.30 group was 27.5％,which was significantly lower than 48.2％ in the ≥0.30 groups (x2 =51.659,P ≤ 0.001).The univariate analysis showed that the patient's sex,the length of the lesion,the degree of tissue differentiation and the VaR value were all factors that significantly affected the recurrence and metastasis of the patients (x2 =13.460,21.111,17.540,39.175,P ≤0.001).Multivariate analysis showed that tissue differentiation and VaR were independent factors affecting recurrence and metastasis of patients (P ≤ 0.001).Conclusions The model can be applied to predict the recurrence and metastasis risk of patients with thoracic esophageal squamous cell carcinoma after radical surgery.

Objective To clarify the significance of chest radiotherapy in the treatment of oligometastatic stage Ⅳ non-small cell lung cancer ( NSCLC ) and to explore the optimal time of interventional therapy during chest radiotherapy. Methods A total of 192 patients with oligometastatic stage Ⅳ NSCLC admitted to Shanxi Provincial Cancer Hospital from 2008 to 2014 were randomly and evenly divided into the chemotherapy alone, radiotherapy+ early intervention, radiotherapy+ middle intervention and radiotherapy+ late intervention groups. Survival analysis was performed with Kanplan-Meier method. Results The median survival of 192 patients with oligometastatic stage Ⅳ NSCLC was 14. 50 months, and the 1-,2-and 3-year survival rates were 57. 4％,24. 0％ and 10. 7％, respectively. The median survivalin the chemotherapy alone, radiotherapy+ early intervention, radiotherapy+ middle intervention and radiotherapy+late intervention groups was 10,21,18 and 13 months, respectively. The 1-year survival rates were 34％, 73％,71％ and 51％,10％,40％,32％ and 13％ for the 2-year survival rates, and 0％,24％,16％ and 3％for the 3-year survival rates ( P=0. 000) . The median survival of patients with radiotherapy dose ≥ 60 Gy and< 60 Gy was 21 and 13 months, 76％ and 53％ for the 1-year survival rates, 34％ and 21％ for the 2-year survival rates, and 17％ and 10％ for the 3-year survival rates ( P=0. 002 ) . Conclusion Early interventional therapy and high-dose radiotherapy can improve the local control rate and prolong the survival time of patients with oligometastatic stage Ⅳ NSCLC.

Objective To analyze the treatment effect and influencing factors of salvage therapy for postoperative recurrence and metastasis patients with pT3N0M0 stage thoracic esophageal squamous cell carcinoma. Methods The clinical data of 174 postoperative recurrence and metastasis patients with pT3N0M0 stage thoracic esophageal squamous cell carcinoma from January 2008 to December 2011 were retrospectively analyzed. The location of recurrence or metastasis, effect of salvage therapy and influencing factors were specifically focused. Results The 1-, 3-and 5-year overall survival rates after recurrence and metastasis in patients with pT3N0M0 stage thoracic esophageal squamous cell carcinoma were 35.0% , 19.3% and 13.3% respectively, and the median survival time was 7 months (95% CI 5.2 to 8.8). Single factor analysis results showed that the gender, age, location of recurrence or metastasis, distant metastasis time and salvage therapy were related to the prognosis in postoperative recurrence and metastasis patients with pT3N0M0 stage thoracic esophageal squamous carcinoma (P＜0.05 or＜0.01), but the weight loss (≥ 5 kg), lesion extent, lesion location, number of lymph node dissection, postoperative adjuvant treatment method and intrathoracic recurrence time were not related to the prognosis in postoperative recurrence and metastasis patients with pT3N0M0 stage thoracic esophageal squamous carcinoma (P＞0.05). Multivariate analysis result showed that the distant metastasis time and salvage therapy were the independent risk factors of prognosis in postoperative recurrence and metastasis patients with pT3N0M0 stage thoracic esophageal squamous carcinoma (P＜0.01). Conclusions Salvage therapy and distant metastasis time are independent risk factors of prognosis in postoperative recurrence and metastasis patients with pT3N0M0 stage thoracic esophageal squamous carcinoma, and chemoradiotherapy or radiotherapy after postoperative recurrence and metastasis in some extent could prolong the survival time.

Objective To investigate the factors associated with postoperative metastasis, recurrence, and survival in patients with stage ⅢA ( N2 ) non?small cell lung cancer ( NSCLC ) , and to provide an objective basis for postoperative radiotherapy in patients. Methods Clinical data were collected from 199 patients who underwent complete resection and were diagnosed with stage ⅢA ( N2 ) NSCLC after surgery in our hospital from 2009 to 2013. The Cox regression model was used for the multivariate analyses of metastasis and recurrence. The survival rates were calculated using the Kaplan?Meier method and analyzed using the log?rank test. Results In the 199 patients, 173 had complete follow?up data. The 1?and 2?year metastasis, recurrence, and survival rates were 38?7%/52?6%, 27?8%/39?1%, and 92?5%/51?4%, respectively. The multivariate analysis showed that pathological type and two positive indices among preoperative CEA/CY211/SCC were two risk factors for metastasis ( P=0?013,0?014) . Positive lymph node number, metastatic lymph node number, lymph node metastasis rate, and two positive indices among preoperative CEA/CY211/SCC were risk factors for recurrence ( P=0?046,0?004,0?028,0?001) . All the above indices were risk factors for low survival rates ( P= 0?013 , 0?011 , 0?002,0?026 ) . Conclusions Patients with stage ⅢA ( N2 ) NSCLC who have positive lymph nodes, lymph node metastases, and two positive indices among preoperative CEA/CY211/SCC may benefit from postoperative radiotherapy.
