BACKGROUND Advanced gastric cancer is a common malignancy that is often diagnosed at an advanced stage and is still at risk of recurrence after radical surgical treatment.Chemoradiotherapy,as one of the important treatment methods for gastric cancer,is of great significance for improving the survival rate of patients.However,the tumor recurrence and survival prognosis of gastric cancer patients after radio-therapy and chemotherapy are still uncertain.AIM To analyze the tumor recurrence after radical radiotherapy and chemotherapy for advanced gastric cancer and provide more in-depth guidance for clinicians.METHODS A retrospective analysis was performed on 171 patients with gastric cancer who received postoperative adjuvant radiotherapy and chemotherapy in our hospital from 2021 to 2023.The Kaplan-Meier method was used to calculate the recurrence rate and survival rate;the log-rank method was used to analyze the single-factor prognosis;and the Cox model was used to analyze the prognosis associated with multiple factors.RESULTS The median follow-up time of the whole group was 63 months,and the follow-up rate was 93.6%.Stage Ⅱ and Ⅲ patients accounted for 31.0%and 66.7%,respec-tively.The incidences of Grade 3 and above acute gastrointestinal reactions and hematological adverse reactions were 8.8%and 9.9%,respectively.A total of 166 patients completed the entire chemoradiotherapy regimen,during which no adverse reaction-related deaths occurred.In terms of the recurrence pattern,17 patients had local recurrence,29 patients had distant metastasis,and 12 patients had peritoneal implantation metastasis.The 1-year,3-year,and 5-year overall survival(OS)rates were 83.7%,66.3%,and 60.0%,respectively.The 1-year,3-year,and 5-year disease-free survival rates were 75.5%,62.7%,and 56.5%,respectively.Multivariate analysis revealed that T stage,peripheral nerve invasion,and the lymph node metastasis rate(LNR)were independent prognostic factors for OS.CONCLUSION Postoperative intensity-modulated radiotherapy combined with chemotherapy for gastric cancer treatment is well tolerated and has acceptable adverse effects,which is beneficial for local tumor control and can improve the long-term survival of patients.The LNR was an independent prognostic factor for OS.For patients with a high risk of local recurrence,postoperative adjuvant chemoradiation should be considered. 展开更多

BACKGROUND For treatment of hilar cholangiocarcinoma(HCCA),the rate of radical resection is low and prognosis is poor,and preoperative evaluation is not sufficiently accurate.3D visualization has the advantage of giving a stereoscopic view,which makes accurate resection of HCCA possible.AIM To establish precise resection of HCCA based on eOrganmap 3D reconstruction and full quantification technology.METHODS We retrospectively analyzed the clinical data of 73 patients who underwent HCCA surgery.All patients were assigned to two groups.The traditional group received traditional 2D imaging planning before surgery(n=35).The eOrganmap group underwent 3D reconstruction and full quantitative technical planning before surgery(n=38).The preoperative evaluation,anatomical classification of hilar hepatic vessels,indicators associated with surgery,postoperative complications,liver function,and stress response indexes were compared between the groups.RESULTS Compared with the traditional group,the amount of intraoperative blood loss in the eOrganmap group was lower,the operating time and postoperative intestinal ventilation time were shorter,and R0 resection rate and lymph node dissection number were higher(P<0.05).The total complication rate in the eOrganmap group was 21.05%compared with 25.71%in the traditional group(P>0.05).The levels of total bilirubin,Albumin(ALB),aspartate transaminase,and alanine transaminase in the eOrganmap group were significantly different from those in the traditional group(intergroup effect:F=450.400,79.120,95.730,and 13.240,respectively;all P<0.001).Total bilirubin,aspartate transaminase,and alanine transaminase in both groups showed a decreasing trend with time(time effect:F=30.270,17.340,and 13.380,respectively;all P<0.001).There was an interaction between patient group and time(interaction effect:F=3.072,2.965,and 2.703,respectively;P=0.0282,0.032,and 0.046,respectively);ALB levels in both groups tended to increase with time(time effect:F=22.490,P<0.001),and there was an interaction effect between groups and time(interaction effect:F=4.607,P=0.004).In the eOrganmap group,there was a high correlation between the actual volume of intraoperative liver specimen resection and the volume of preoperative virtual liver resection(t=0.916,P<0.001).CONCLUSION The establishment of accurate laparoscopic resection of hilar cholangiocarcinoma based on preoperative eOrganmap 3D reconstruction and full quantization technology can make laparoscopic resection of hilar cholangiocarcinoma more accurate and safe. 展开更多
