Objectives. To investigate the prognostic impact of the number of dissected lymph nodes (LNs) in gastric cancer after curative distal gastrectomy.Methods. The survival of 634 patients who underwent curative distal gastrectomy from 1995 to 2004 was retrieved. Long-term surgical outcomes and associations between the number of dissected LNs and the 5-year survival rate were investigated.Results. The number of dissected LNs was one of the most important prognostic indicators. Among patients with comparable T category, the larger the number of dissected LNs was, the better the survival would be (). The linear regression showed that a significant survival improvement based on increasing retrieved LNs for stage II, III and IV (). A cut-point analysis yields the greatest variance of survival rate difference at the levels of 15 LNs (stage I), 25 LNs (stage II) and 30 LNs (stage III).Conclusion. The number of dissected LNs is an independent prognostic factor for gastric cancer. To improve the long-term survival of patients with gastric cancer, removing at least 15 LNs for stage I, 25 LNs for stage II, and 30 LNs for stage III patients during curative distal gastrectomy is recommended.

166 Background: We introduced laparoscopy-assisted distal gastrectomy (LADG) as multi-institutional feasibility study, and already reported that the overall morbidity rate was 1.6% in the study (Gastric Cancer 2012). The aim of this study is to evaluate the long-term survival results of the patients who were enrolled to the study and finished 5-year follow-up. Methods: A total of 165 c-stage I gastric cancer patients who were registered from Kanagawa Cancer Center were included to the study. The Kaplan-Meier method was used to evaluate overall survival and recurrence-free survival. Results: Median follow-up period of the patients was 1901 days. The reconstruction methods were either B-I (n=150), R-Y (n=14), or B-II (n=1). The accuracy for preoperative diagnosis of stage I was 87.2% (144/165). Among 14 patients with p-stage II/III excluding T3N0/T1N2-3, eight patients received postoperative adjuvant chemotherapy. The recurrence rates by pathological stage were 0% (0/123) for stage IA, 4.7% (1/21) for stage IB, 6.2% (1/16) for stage II, and 60% (3/5) for stage III/IV, respectively. The organ of recurrence was mainly observed in liver (n=3), followed by bone, lymph node, peritoneum (n=1). The 5-year recurrence-free survival rates were 94.5% for all patients, 97.2%/92.3%/60% for pT1/pT2/pT3/4, 98.5%/82.4%/71.4%/66.7% for pN0/pN1/pN2/pN3, 97.9%/81.3%/40% for p-stage I/p-stage II/p-stage III/IV. Conclusions: LADG for c-stage I gastric cancer was feasible in long-term result, as well as in short-term outcome.

Background: Laparoscopic total gastrectomy (LTG) for advanced gastric cancer (AGC) is a technically and oncologically challenging procedure for surgeons. Objectives: The aim of this study was to compare the technical safety and long-term oncological feasibility between LTG and open total gastrectomy (OTG) for patients with AGC using a propensity score (PS)-matched analysis. Methods: Between 2004 and 2014, 185 patients (OTG: 127, LTG: 58) underwent curative total gastrectomy for AGC. PS matching was performed using the patients’ clinicopathological factors, and comparisons were made based on surgical outcomes and long-term survival rates. Results: After PS matching, 102 patients (51 patients in each group) were enrolled. The total numbers of retrieved lymph nodes were similar in both groups. The numbers of retrieved lymph nodes around the splenic hilum were similar in both groups. A longer operation time was required for the LTG group than for the OTG group, but less intraoperative bleeding was observed in the LTG group. The overall morbidity and mortality rates of both groups were similar. Between the 2 groups, there was no difference in the 5-year overall survival rate or disease-free survival rate. Conclusions: For treating proximal AGC, LTG may be a technically and an oncologically safe and feasible method.

Background: Two members from an academic tertiary hospital went to the National Cancer Institute in Tokyo, Japan, to learn how to perform an adequate D2 lymphadenectomy and to then introduce this technique in the surgical care of patients undergoing surgery for gastric cancer at a Western hospital. We aimed to compare the perioperative outcomes and long-term survival of Western patients who underwent gastric resection, performed by these 2 surgeons, before and after the surgeons’ shortcourse technical training in Japan. Methods: We conducted a retrospective comparative study of all patients (n = 27 before training and n = 79 after training) who underwent gastric resection for cancer by the same 2 surgeons between September 2007 and December 2017 at the Centre Hospitalier Universitaire de Québec — Université Laval (Québec, Canada). We collected data on patient demographic, clinical, surgical, pathological and treatment characteristics, as well as long-term survival and complications. Results: In the post-training group, the number of sampled lymph nodes was higher (median 33 v. 14, p < 0.0001), but this increase did not result in a higher number of histologically positive lymph nodes (p = 0.35). The rate of complications was lower in the post-training group (15.2% v. 48.2%, p = 0.002). The hospital stay was shorter in the post-training group (11 [standard deviation (SD) 7] v. 23 [SD 45] d, p = 0.03). The median survival was higher in the post-training group (47 v. 29 mo, p = 0.03). Conclusion: These results suggest that a short-course technical training in D2 lymphadenectomy, completed in Japan, improved lymph node sampling, decreased postoperative complications and improved survival of patients undergoing surgery for gastric cancer in a Western setting.

We analyzed long-term outcomes of the treatment of 217 patients (men - 126, women - 91), who underwent radical operations for stomach cancer in the period of 1972 till 1976. 14 patients were under 39, 52 - from 40 to 49, 50 to 59 - 52, 60 to 69 - 80, over 70 years old - 19. The youngest patient was 28 years old and the oldest - 76 years old. Most patients (185) were operated on at stage III of the disease, stage II was diagnosed in 27 patients, and stage IV - in 5 patients.

e14131 Background: To evaluate retrospectively long-term survival of 594 patients with colorectal liver metastases treated with MR-guided laser-induced thermotherapy (LITT) depending on different factors. Methods: 594 patients with liver metastases from colorectal carcinoma treated with MR-guided LITT between 01/99 and 12/10 were included. For survival analysis tumor localization, TNM classification, number of metastases, diameter and volume of metastases and necrosis, lobular spread, number of treatment sessions, performance of adjuvant chemotherapy and transarterial chemoembolisation were considered. The Kaplan-Meier method was used to conduct this survival analysis. Results: Log-rank test showed statistically significant differences between survival curves, multivariate Cox-regression-analysis (p<0.05) showed prognostic factors regarding overall survival like number of metastases pre intervention, adjuvant chemotherapy, diameter of metastases, ratio of volumes of necrosis and metastases, and affected lymph nodes. Median overall survival rate at the time of first LITT was 25 months, 1-year survival: 78%, 2-year survival: 50.1%, 3-year survival: 28%; 4-year survival: 16.4%; 5-year survival: 7.8%. Numbers of metastases pre intervention: 1-2 metastases with a median survival rate of 60 months; 3-4 metastases: 45 months; ≥5 metastases: 42 months. Median survival rate for metastases <20mm in diameter 36 months; 20-30mm 27 months, 30-40mm 24 months and >40mm 21 months. Affected lymph nodes: median survival rate for patients with N0-classification 30 months, N1-classification 24 months; N2/N3/N4-classification 22 months. Conclusions: Multivariate Cox regression model provided the minimal number of significant variables with the maximal prognostic value concerning overall survival for MR-guided LITT, i.e., diameter and number of metastases and primary classification of lymph nodes.

Abstract Purpose The potential additive influence of adjuvant chemotherapy (AC) on prognosis of patients with stage II/III gastric cancer (GC) who experienced complications after radical surgery is unclear.Methods The whole group was divided into a postoperative complication (PC) group and a postoperative non-complication (NPC) group, and the overall survival (OS) rate, recurrence-free survival (RFS) rate and recurrence rate were compared between the two groups of patients. Results A total of 1563 patients between January 2010 and December 2015 in our center were included in this analysis. There were 268 patients (17.14%) in the PC group and 1295 patients (82.86%) in the NPC group. The 5-year OS rate of the PC group was 55.2%, the NPC group was 63.3%; and the 5-year RFS rate of the PC group was 53.7%, the non-PC group was 58.8%. Recurrence patterns showed no significant difference between the two group (all p>0.05). Adjuvant chemotherapy (AC) significantly improved the OS and RFS rates of patients with and without PCs (both p<0.05), and it showed no significant difference between the PC group and the NPC group who received AC (both p> 0.05). Stratified analysis showed that AC only improve the OS or RFS rates of stage III patients (both p<0.05). Further stratified analysis of the time interval (TI) from operation to initiation of AC in the PC group showed that a TI after 6 weeks (≥6eeks) improved only the OS and RFS rates of stage III patients, while when a TI within 6 weeks (<6weeks), a benefit was observed in stage II and III patients (both p<0.05).Conclusion AC can abolish the negative effect of PCs on the long-term survival of patients with stage III GC; for stage II patients, the above offset effect is affected by the TI. Delaying AC initiation after 6 weeks may not improve the survival of patients experienced stage II GC with complications.

Abstract Background The incidence of remnant gastric cancer (RGC) after distal gastrectomy is 1–5%. However, as the survival rate of patients with gastric cancer improves due to early detection and treatment, more patients may develop RGC. There is no consensus on the surgical and postoperative management of RGC, and the clinicopathological characteristics correlated with the long-term outcomes remain unclear. Therefore, we investigated the clinicopathological factors associated with the long-term outcomes of RGC. Methods We included 65 consecutive patients who underwent gastrectomy for RGC from January 2000 to December 2015 at the Osaka Medical and Pharmaceutical University Hospital, Japan. The Kaplan–Meier method was used to create survival curves, and differences in survival were compared between the groups (clinical factors, pathological factors, and surgical factors) using the log-rank test. Multivariate analyses using the Cox proportional hazard model were used to identify factors associated with long-term survival. Results No significant differences were noted in the survival rate based on clinical factors (age, body mass index, diabetes mellitus, hypertension, cardiovascular disease, pulmonary complications, liver disease, diet, history of alcohol drinking, and history of smoking) or the type of remnant gastrectomy. Significant differences were noted in the survival rate based on pathological factors and surgical characteristics (intraoperative blood loss, operation time, and the number of positive lymph nodes). Multivariate analysis revealed that the T stage (hazard ratio, 5.593; 95% confidence interval [CI], 1.183–26.452; p = 0.030) and venous invasion (hazard ratio, 3.351; 95% CI, 1.030–10.903; p = 0.045) were significant independent risk factors for long-term survival in patients who underwent radical resection for RGC. Conclusions T stage and venous invasion are important prognostic factors of long-term survival after remnant gastrectomy for RGC and may be keys to managing and identifying therapeutic strategies for improving prognosis in RGC.
