RESUMO

Purpose@#Despite scientific evidence regarding laparoscopic gastrectomy (LG) for advanced gastric cancer treatment, its application in patients receiving neoadjuvant chemotherapy remains uncertain. @*Materials and Methods@#We used the 2019 Korean Gastric Cancer Association nationwide survey database to extract data from 489 patients with primary gastric cancer who received neoadjuvant chemotherapy. After propensity score matching analysis, we compared the surgical outcomes of 97 patients who underwent LG and 97 patients who underwent open gastrectomy (OG). We investigated the risk factors for postoperative complications using multivariate analysis. @*Results@#The operative time was significantly shorter in the OG group. Patients in the LG group had significantly less blood loss than those in the OG group. Hospital stay and overall postoperative complications were similar between the two groups. The incidence of Clavien– Dindo grade ≥3 complications in the LG group was comparable with that in the OG group (1.03% vs. 4.12%, P=0.215). No statistically significant difference was observed in the number of harvested lymph nodes between the two groups (38.60 vs. 35.79, P=0.182). Multivariate analysis identified body mass index (odds ratio [OR], 1.824; 95% confidence interval [CI], 1.029–3.234; P=0.040) and extent of resection (OR, 3.154; 95% CI, 1.084–9.174; P=0.035) as independent risk factors for overall postoperative complications. @*Conclusions@#Using a large nationwide multicenter survey database, we demonstrated that LG and OG had comparable short-term outcomes in patients with gastric cancer who received neoadjuvant chemotherapy.

RESUMO

Purpose@#The number of bariatric surgeries performed at our tertiary hospital has gradually increased since the national health insurance began to cover their expenses in January of 2019. This study examined the early surgical outcomes of laparoscopic sleeve gastrectomy (LSG) performed by experienced gastric cancer surgeons. @*Materials and Methods@#We retrospectively reviewed and analyzed data from 50 patients who underwent LSG between November of 2018 and April of 2020 at the Asan Medical Center by 1 of 5 experienced surgeons each of whom performed approximately 100–300 cases of gastrectomy annually. The age, body mass index (BMI), weight, presence of comorbidities, operation time, hospital stay after surgery, postoperative complications, postoperative excess weight loss (EWL), and resolution of comorbidities were examined. @*Results@#The mean age, BMI, and weight were 37.29±9.77 years, 37.12 kg/m2, and 102.00 kg, respectively. The mean operation time and postoperative length of hospital stay were 109.59±35.88 and 5.06±1.20 days, respectively. Two patients (4.00%) had early postoperative complications and postoperative leakage; bleeding and stenosis were not reported. The EWL after 1 and 6 months of operation was 26.55% and 60.34%, respectively. The resolution of diabetes, hypertension, and dyslipidemia after 6 months of operation was 88.89%, 54.54%, and 50.00%, respectively. @*Conclusion@#LSG is safe and effective when performed by an experienced gastric cancer surgeon; however, a long-term follow-up of patients is required.

RESUMO

PURPOSE: Insistence that total regression of primary tumor would not represent long-term oncologic outcomes has been raised. Therefore, this study aimed to evaluate the outcomes of these patients after preoperative chemoradiotherapy (PCRT) and radical surgery and to evaluate the associated risk factors. METHODS: We included 189 patients with rectal cancer who showed total regression of the primary tumor after PCRT, followed by radical resection, between 2001 and 2012. Recurrence-free survival (RFS) was calculated using the Kaplan-Meier method, and the results were compared with 77 patients with Tis rectal cancer who received only radical resection. Factors associated with RFS were evaluated using Cox regression analysis. RESULTS: Sphincter-saving resection was performed for 146 patients (77.2%). Adjuvant chemotherapy was administered to 168 patients (88.9%). During the follow-up period, recurrence occurred in 17 patients (9%). The 5-year RFS was 91.3%, which was significantly lower than that of patients with Tis rectal cancer without PCRT (P = 0.005). In univariate analysis, preoperative CEA and histologic differentiation were associated with RFS. However, no factors were found to be associated with RFS. CONCLUSION: RFS was lower in patients with total regression of primary rectal cancer after PCRT than in those with Tis rectal cancer without PCRT, and it would not be considered as the same entity with early rectal cancer or “disappeared tumor” status.
