Effect of High Body Mass Index on Short- and Long-term Outcomes of Patients who Underwent Laparoscopic Gastrectomy for Advanced Gastric Cancer: A Case Control Study

Abstract Background High body mass index (BMI) is thought to be a preoperative risk factor for surgical treatment. Until now, few studies have investigated the long-term impact of preoperative high BMI on advanced gastric cancer (GC) patients who underwent laparoscopic gastrectomy (LG). Therefore, the present study was designed to compare clinical outcomes between high BMI and normal BMI patients who underwent LG. MethodsWe retrospectively investigated 282 pathological stage II~III GC cases who underwent radical LG plus D2 lymphadenectomy from February 2009 to May 2018. Based on the China BMI classification, the patients were classified into a high (BMI ≥ 24 kg/m2) or normal (BMI < 24 kg/m2) BMI group. The clinical characteristics, intraoperative findings, short-term and long-term outcomes of the two groups of patients were then compared. Results The high BMI group had longer operation time (160.1 ± 36.0 minutes vs. 147.7 ± 33.7 minutes; P = 0.005) and greater intraoperative bleeding (138.3 ± 239.4ml vs. 86.6 ± 67.7ml; P = 0.002) compared to the normal BMI group. Moreover, shorter time to flatus, starting the soft diet, removing drain tube and length of stay (all P < 0.05) were observed in the high BMI patients. However, there was no significant difference in relapse-free survival or overall survival between the two groups. Conclusion Patients with high BMI was associated with longer operation time and greater amount of intraoperative bleeding but had faster recovery as compared to those with normal BMI. Also, LG can be considered as safe with no significant difference in terms of short- and long-term outcomes on the peri- and post-operative outcomes between the two BMI groups of patients. Nevertheless, these surgeries for high BMI patients should be performed by experienced surgeons.

82 Background: Radical gastrectomy followed by adjuvant chemotherapy for advanced gastric cancer brings about serious nutritional impairment. Recent studies have shown an association between body mass index (BMI) and perioperative outcomes of gastric cancer. However, little is known about the association between BMI and long-term outcomes of advanced gastric cancer. Our study evaluated the clinical impact of BMI on the long-term outcomes of gastric cancer staged at II and III, treated by radical gastrectomy followed by adjuvant chemotherapy. Methods: We analysed a total of 211 cases of advanced gastric cancer stage II and III between January 2005 and December 2010 at Chung-Ang University Hospital. The patients were divided into 4 groups according to BMI; underweight, normal, overweight, and obese. In addition, they were divided into two groups (BMI-High vs BMI-Low). We assessed age, sex, tumor location, lymph node involvement, operation method, initial cancer stage, recurrence, and survival (overall survival and disease free survival) between two groups. Results: We classified them into 4 groups according to BMI; underweight, normal, overweight, and obese. There was no difference in overall survival between normal, overweight, and obese group. However, there was significant difference between underweight group and the other groups. As for disease free survival, similar findings were observed. Among 211 patients, 154 patients (72.9%) were included in BMI-L (body mass index < 25), whereas 57 patients (27.1%) in BMI-H (body mass index ≥ 25). There was no difference in age, sex, tumor location, stage, lymph node involvement, operation method, recurrence, and cancer-related death between two groups. When classified into 4 groups as stage II in BMI-H, stage II in BMI-L, stage III in BMI-H, and stage III in BMI-L, overall survival showed significant difference in stage, however, no difference between BMI-H and BMI-L. Disease free survival showed no significant difference in stage and BMI, especially, no significant difference between stage II in BMI-L and stage III in BMI –H. Conclusions: Our findings suggest that preoperative BMI may predict the long term outcomes of advanced gastric cancer after radical surgery and chemotherapy.

369 Background: To investigate the oncological feasibility and technical safety of laparoscopic gastrectomy with D2 lymphadenectomy for advanced gastric cancer. Methods: 186 advanced gastric cancer patients treated by gastrectomy with D2 lymphadenectomy were eligible for inclusion including those with invasion into the muscularis propria, subserosa, and serosa without involvement of other organs, and stages N0–2 and M0. We retrospectively compared the short- and-long term outcomes between laparoscopic gastrectomy and open gastrectomy. Results: We analyzed short-term outcomes by comparing distal- with total gastrectomy results. We found no significant difference for distal gastrectomy for postoperative morbidity (laparoscopic vs. open: n = 4 (4.6%) vs. n = 1 (3.6%); p= 1.00). We also found no significant difference in postoperative morbidity for total gastrectomy (laparoscopic vs. open: n = 2 (4.0%) vs. n = 1 (4.0%); p= 1.00). No deaths occurred in any group. The entire cohort analysis revealed no statistically significant differences in overall- or recurrence-free survival between the laparoscopic and open groups. For overall survival, there were no significant differences between open and laparoscopic groups for clinical stage II or III ( p= 0.29 and 0.27, respectively), and for pathological stage II or III ( p= 0.88 and 0.86, respectively). For recurrence-free survival, there were no significant differences between open and laparoscopic groups for clinical stage II or III ( p= 0.63 and 0.60, respectively), and for pathological stage II or III (p = 0.98 and 0.72, respectively). Conclusions: Laparscopic gastrectomy for advanced gastric cancer compared favorably with open gastrectomy regarding short- and long-term outcomes. Clinical trial information: 160907.

Abstract Background Since 2010, laparoscopic transanal total mesorectal excision (TaTME) has been increasingly used for low and very low rectal cancer. It is supposed to improve visibility and access to the dissection planes in the pelvis. This study reports on short- and long-term outcomes of the first 100 consecutive patients treated with TaTME in a certified German colorectal cancer center. Patients and methods Data were derived from digital patient files and official cancer registry reports for patients with TaTME tumor surgery between July 2014 and January 2020. The primary outcome was the 3-year local recurrence rate and local recurrence-free survival (LRFS). Secondary endpoints included overall survival (OAS), disease-free survival (DFS), operation time, completeness of local tumor resection, lymph node resection, and postoperative complications. The Kaplan–Meier method was employed for the survival analyses; competing risks were considered in the time-to-event analysis. Results During the observation period, the average annual operation time decreased from 272 to 178 min. Complete local tumor resection was achieved in 97% of the procedures. Major postoperative complications (Clavien–Dindo 3–4) occurred in 11% of the cases. At a median follow-up time of 2.7 years, three patients had suffered from a local recurrence. Considering competing risks, this corresponds to a 3-year cumulative incidence rate for local recurrence of 2.2% and a 3-year LRFS of 81.9%. 3-year OAS was 82.9%, and 3-year DFS was 75.7%. Conclusion TaTME is associated with favorable short and long-term outcomes. Since it is technically demanding, structured training programs and more research on the topic are indispensable.

Abstract Nowadays, there is still no consensus about the benefits of adding neck lymphadenectomy to the traditional two-fields esophagectomy. An extended lymphadenectomy could potentially increase operation time and the risks for postoperative complications. However, extended lymphadenectomy allows resection of cervical nodes at risk for metastases, potentially increasing long-term survival rates. This study aims to estimate whether cervical prophylactic lymphadenectomy for esophageal cancer influences short- and long-term outcomes through a systematic review of literature and meta-analysis. Methods A systematic review was conducted in PubMed, Embase, Cochrane Library Central, and Lilacs (BVS). The inclusion criteria were: (1) studies that compare two-field vs. three-field esophagectomy; (2) adults (>18 years); (3) articles that analyze short- or long-term outcomes; and (4) clinical trials or cohort studies. The results were summarized by forest plots, with effect size (ES) or risk difference (RD) and 95% CI. Results Twenty-five articles were selected, comprising 8,954 patients. Three-field lymphadenectomy was associated to higher operation time (ES: -1.51; 95%CI -1.84, −1.18) and higher blood loss (ES: -0.24; 95%CI: −0.37, −0.11). Also, neck lymphadenectomy inputs additional risk for pulmonary complications (RD: 0.03; 95%CI: 0.01, 0.05). No difference was noted for morbidity (RD: 0.01; 95%CI: −0.01, 0.03); leak (−0.02; 95%CI: −0.07, 0.03); postoperative mortality (RD: 0.00; 95%CI: −0.00, 0.01), and hospital stay (ES: -0.05; 95%CI -0.20, 0.10). Three-field lymphadenectomy allowed higher number of retrieved lymph nodes (MD: -1.51; 95%CI -1.84, −1.18), but did not increase the overall survival (HR: 1.11; 95%CI: 0.96, 1.26). Conclusion Prophylactic neck lymphadenectomy for esophageal cancer should be performed with caution once it is associated with poorer short-term outcomes compared to traditional two-field lymphadenectomy and does not improve long-term survival. Future esophageal cancer studies should determine the subgroup of patients who could benefit from prophylactic neck lymphadenectomy in long-term outcomes.

Objective To compare the short- and long-term outcomes of radiofrequency ablation (RFA) versus liver resection and chemotherapy for liver metastases from gastric cancer. Methods We retrospectively evaluated 50 patients who underwent curative gastrectomy and local treatments for liver metastases (RFA, n = 20; liver resection, n = 20; and chemotherapy, n = 10) from 2008 to 2018. Results The short- and long-term outcomes of each local treatment were evaluated. The median overall survival (OS) after RFA was similar to that after liver resection (20 vs. 20 months, respectively) and longer than that after chemotherapy (20 vs. 10 months, respectively). The 3-year OS and progression-free survival (PFS) rates after RFA were 20% and 10%, respectively, while those in the liver resection group were 23.5% and 23.5%, respectively. The 3-year OS rate after chemotherapy was 10%. The size and number of metastases were prognostic factors for patients with gastric cancer with liver metastasis without statistical significance. Conclusions Among patients with liver metastasis from gastric cancer, OS and PFS were satisfactory and comparable between RFA and liver resection but better than those of chemotherapy. RFA is an appropriate option for patients with gastric cancer who have a solitary liver metastasis measuring ≤3.0 cm.

Donor System

Background. In China, the cases of liver transplantation (LT) from donation after citizens’ death have rose year by year since the citizen-based voluntary organ donor system was initiated in 2010. The objective of our research was to investigate the early postoperative and late long-term outcomes of LT from donation after brain death (DBD) and donation after circulatory death (DCD) according to the current organ donation system in China. Methods. Sixty-two consecutive cases of LT from donation after citizens’ death performed in our hospital between February 2012 and June 2017 were examined retrospectively for short- and long-term outcomes. These included 35 DCD LT and 27 DBD LT. Result. Subsequent median follow-up time of 19 months and 1- and 3-year graft survival rates were comparative between the DBD group and the DCD group (81.5% and 66.7% versus 67.1% and 59.7%; P=0.550), as were patient survival rates (85.2% and 68.7% versus 72.2% and 63.9%; P=0.358). The duration of ICU stay of recipients was significantly shorter in the DBD group, in comparison with that of the DCD group (1 versus 3 days, P=0.001). Severe complication incidence (≥grade III) after transplantation was identical among the DBD and DCD groups (48.1% versus 60%, P=0.352). There was no significant difference in postoperative mortality between the DBD and DCD groups (3 of 27 cases versus 5 of 35 cases). Twenty-one grafts (33.8%) were lost and 18 recipients (29.0%) were dead till the time of follow-up. Malignancy recurrence was the most prevalent reason for patient death (38.8%). There was no significant difference in incidence of biliary stenosis between the DBD and DCD groups (5 of 27 cases versus 6 of 35 cases, P=0.846). Conclusion. Although the sample size was small to some extent, this single-center study first reported that LT from DCD donors showed similar short- and long-term outcomes with DBD donors and justified the widespread implementation of voluntary citizen-based deceased organ donation in China. However, the results should be verified with a multicenter larger study.
