| 1 | Pain threshold, anxiety and other factors affect intensity of postoperative pain in gastric cancer patients: A prospective cohort study显示文摘Objective: This prospective cohort study explored factors related to postoperative pain in gastric cancer patients.Methods: A total of 236 patients who underwent gastrectomy were enrolled. All patients enrolled in the study completed the Hospital Anxiety and Depression Scale(HADS) questionnaire and Life Orientation Test-Revised(LOT-R) questionnaire on the day before surgery. Heat pain threshold(HPT), cold pain threshold(CPT) and pressure pain threshold(PPT) were measured for all patients one day prior to surgery and demographic details were collected. All patients were connected to a patient-controlled intravenous analgesia(PCIA) pump at the end of the surgery. The occurrence of postoperative pain was used as a dependent variable, and multivariate logistic regression analyses were conducted to screen for factors affecting postoperative pain.Results: In total, 83 patients(35.2%) had postoperative pain. Body mass index(BMI) ≥28 kg/m^(2) [odds ratio(OR): 2.67;95% confidence interval(95% CI): 1.07-6.67], total gastrectomy(OR: 2.64;95% CI: 1.42-4.91),preoperative anxiety score ≥8(OR: 2.37;95% CI: 1.12-5.02), heat pain threshold ≤4.9 s(OR: 2.14;95% CI:1.06-4.32), pressure pain threshold ≤4 g(OR: 2.05;95% CI: 1.05-4.03), and female gender(OR: 1.99;95% CI:1.04-3.83) were risk factors for postoperative pain.Conclusions: Obesity, wide range of gastrectomy, high preoperative anxiety, low HPT and PPT, and female gender are associated with increased risk for postoperative pain. | Hongyu Tan Jin Wei Shuo Li Ling Yu Hongwei Sun Ke Ji Yinkui Wang Changlong Li | 2021 | Chinese Journal of Cancer Research2021，33，3： | 5 |
| 2 | Laparoscopic vs.open lower mediastinal lymphadenectomy for Siewert typeⅡ/Ⅲadenocarcinoma of esophagogastric junction:An exploratory,observational,prospective,IDEAL stage2b cohort study(CLASS-10 study)显示文摘Objective:This study aims to verify the feasibility and efficacy of laparoscopic lower mediastinal lymphadenectomy for Siewert typeⅡ/Ⅲadenocarcinoma of esophagogastric junction(AEG).Setting:An exploratory,observational,prospective,cohort study will be carried out under the Idea,Development,Exploration,Assessment and Long-term Follow-up(IDEAL)framework(stage 2 b).Paritcipants:The study will recruit 1,036 patients with cases of locally advanced AEG(Siewert typeⅡ/Ⅲ,clinical stage cT2-4 aN0-3 M0),and 518 will be assigned to either the laparoscopy group or the open group.Interventions:Patients will receive lower mediastinal lymphadenectomy along with either total or proximal gastrectomy.Primary and secondary outcome measures:The primary endpoint is the number of lower mediastinal lymph nodes retrieved,and the secondary endpoints are the surgical safety and prognosis,including intraoperative and postoperative lower-mediastinal-lymphadenectomy-related morbidity and mortality,rate of rehospitalization,R0 resection rate,3-year local recurrence rate,and 3-year overall survival.Conclusions:The study will provide data for the guidance and development of surgical treatment strategies for AEG.Trial registration number:The study has been registered in ClinicalTrials.gov(No.NCT04443478). | Shuangxi Li Xiangji Ying Fei Shan Yongning Jia Zhemin Li Kan Xue Rulin Miao Yinkui Wang Zhaode Bu Xiangqian Su Ziyu Li Jiafu Ji | 2022 | Chinese Journal of Cancer Research2022，34，4： | 3 |
| 3 | Exploration and optimization of surgical techniques for laparoscopic transhiatal lower mediastinal lymph node dissection for adenocarcinoma of esophagogastric junction: A prospective IDEAL 2a study with qualitative design显示文摘Objective: To explore the change and feasibility of surgical techniques of laparoscopic transhiatal(TH)-lower mediastinal lymph node dissection(LMLND) for adenocarcinoma of the esophagogastric junction(AEG)according to Idea, Development, Exploration, Assessment, and Long-term follow-up(IDEAL) 2a standards.Methods: Patients diagnosed with AEG who underwent laparoscopic TH-LMLND were prospectively included from April 14, 2020, to March 26, 2021. Clinical and pathological information as well as surgical outcomes were quantitatively analyzed. Semistructured interviews with the surgeon after each operation were qualitatively analyzed.Results: Thirty-five patients were included. There were no cases of transition to open surgery, but three cases involved combination with transthoracic surgery. In qualitative analysis, 108 items under three main themes were detected: explosion, dissection, and reconstruction. Revised instruction was subsequently designed according to the change in surgical technique and the cognitive process behind it. Three patients had anastomotic leaks postoperatively, with one classified as Clavien-Dindo Ⅲa.Conclusions: The surgical technique of laparoscopic TH-LMLND is stable and feasible;further IDEAL 2b research is warranted. | Yinkui Wang Fanling Hong Shuangxi Li Fei Shan Yongning Jia Rulin Miao Zhemin Li Ziyu Li Jiafu Ji | 2023 | Chinese Journal of Cancer Research2023，35，2： | 0 |
| 4 | Correlation between imaging features on computed tomography and combined positive score of PD-L1 expression in patients with gastric cancer显示文摘Objective:To explore the correlation between computed tomography(CT)features and combined positive score(CPS)of programmed cell death ligand 1(PD-L1)expression in patients with gastric cancer(GC).Methods:This study reviewed an institutional database of patients who underwent GC operation without neoadjuvant chemotherapy between December 2019 and September 2020.The CPS results of PD-L1 expression of postoperative histological examination were recorded by pathology.Baseline CT features were measured,and their correlation with CPS 5 or 10 score groups of PD-L1 expression was analyzed.Results:Data for 153 patients with GC were collected.Among them,124 were advanced GC patients,and 29were early GC patients.None of the CT features significantly differed between CPS groups with a cutoff score of 5and a score of 10 in patients with early GC.In advanced GC,the presence of lymph nodes with short diameters>10mm was significantly different(P=0.024)between the CPS<5 and CPS≥5 groups.CT features such as tumor attenuation in the arterial phase,long and short diameter of the largest lymph node,the sum of long diameter of the two largest lymph nodes,the sum of short diameter of the two largest lymph nodes,and the presence of lymph nodes with short diameters>10 mm significantly differed between the CPS<10 and CPS≥10 groups in advanced GC.The sensitivity,specificity and area under receiver operating characteristic(ROC)curve of logistic regression model for predicting CPS≥10 was 71.7%,50.0%and 0.671,respectively.Microsatellite instability(MSI)status was significantly different in CPS groups with cutoff score of 5 and 10 in advanced GC patients.Conclusions:CT findings of advanced GC patients with CPS≥10 showed greater arterial phase enhancement and larger lymph nodes.CT has the potential to help screen patients suitable for immunotherapy. | Zhilong Wang Yinkui Wang Xiaoting Li Yanling Li Zhaode Bu Zhongwu Li Yingshi Sun Jiafu Ji | 2022 | Chinese Journal of Cancer Research2022，34，5： | 0 |
