Objective:To investigate the occurrence of non-diabetic hyperglycemia after anterior mediastinal tumor resection via lateral thoracic approach single-port thoracoscopy and its impact on postoperative complications.Methods:The medical records of 182 anterior mediastinal tumors admitted to the Nanjing Brain Hospital (Nanjing Chest Hospital) from January 2022 to March 2024 were retrospectively analyzed. All patients underwent anterior mediastinal tumor resection via lateral thoracic approach single-port thoracoscopy. They were divided into the hyperglycemia group ( n=54) and non-hyperglycemia group ( n=128) according to the occurrence of postoperative non-diabetic hyperglycemia. The postoperative complications were compared between the two groups. Patients with any complication showing statistically significant differences between the two groups were included in the complication group, and the remaining patients were included in the non-complication group. Binary logistic regression model was used to analyze the risk factors for postoperative complications in patients undergoing anterior mediastinal tumor resection via lateral thoracic approach single-port thoracoscopy. Results:The incidences of postoperative pain, wound fat liquefaction, wound infection, and pulmonary infection in the hyperglycemia group were significantly higher than those in the non-hyperglycemia group (all P<0.05). There were statistically significant differences in age, history of hypertension, triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), operation time, and postoperative hyperglycemia between the complication group and non-complication group (all P<0.05). Multivariate logistic regression analysis showed that age, history of hypertension, operation time, and postoperative hyperglycemia were independent risk factors for postoperative pain/wound fat liquefaction/wound infection/pulmonary infection in patients undergoing anterior mediastinal tumor resection via lateral thoracic approach single-port thoracoscopy (all P<0.05). Conclusions:Non-diabetic postoperative hyperglycemia can increase the risk of postoperative pain/wound fat liquefaction/wound infection/pulmonary infection in patients undergoing anterior mediastinal tumor resection via lateral thoracic approach single-port thoracoscopy, and it is an independent risk factor for the above postoperative complications.

Objective To retrospectively compare the efficacy and toxicity between intensity?modulated radiotherapy ( IMRT ) combined with chemotherapy plus targeted therapy and IMRT combined with chemotherapy in the treatment of patients with locally advanced nasopharyngeal carcinoma ( NPC) , and to preliminarily evaluate the necessity of adding targeted drugs to standard chemoradiotherapy . Methods Forty?two patients with stage Ⅲ?Ⅳb NPC who received IMRT combined with concurrent ± adjuvant chemotherapy plus targeted molecular therapy from January 2007 to December 2012 were assigned to experiment group,while 168 patients who received IMRT combined with concurrent ±adjuvant chemotherapy within the same period were assigned to control group. The experiment group was paired with the control group at a ratio of 1vs.4.The survival rates were caculated using Kaplan?Meier method and analyzed using log?rank method,other comparison was perfomed by χ2?test. Results The follow?up rate was 100%.The sample size of experiment group and control group were 42 patients and 168 patients. There were no significant differences in the 3?year OS, LRFS, or DMFS rates between the experiment group and the control group (94?3% vs. 87?3%, P=0?647;100?0% vs. 94?6%,P=0?193;92?2% vs. 89?1%, P=0?744).There were also no significant differences in the incidence rates of grade Ⅲ?Ⅳ gastrointestinal reaction or marrow suppression between the two groups ( 7?1%( 3/42 ) vs. 3?6%( 6/168 ) , P=0?388;26?2%( 11/42 ) vs. 17?3%(29/168),P=0?272).However,the experiment group had significantly higher incidence of grade Ⅲ?Ⅳoral mucositis than the control group ( 40?5%( 17/42 ) vs . 14?9%( 25/168 ) , P=0?000 ) . Conclusions The preliminary results indicate that IMRT combined with chemotherapy plus targeted molecular therapy is not able to substantially improve the OS, LRFS, or DMFS rates in patients with locally advanced NPC. Moreover, it may aggravate radiochemotherapy?induced oral mucositis.
