Abstract
OBJECTIVE The role of splenectomy on cytoreductive surgery in patients with ovarian cancer remains controversial. We conducted this meta-analysis to evaluate the safety and impact of survival outcome of splenectomy in patients with ovarian cancer. METHODS In this meta-analysis we analyzed studies published in PubMed, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), International Clinical Trials Registry Platform (ICTRP), and Clinical Trials. gov that appeared in our search from inception to November 10, 2023. RESULT This meta-analysis included 10 studies, totaling 6297 patients, comprising one prospective and nine retrospective analyses. The results indicated no significant disparity in overall survival and mortality (OR 1.14, 95% CI 0.69 to 1.87, p=0.62) between the splenectomy cohort and the no splenectomy (required) cohort. Furthermore, relative to the no splenectomy (required) cohort, the splenectomy group showed a heightened incidence of overall post-operative complications (odds ratio (OR) 1.66, 95% CI 1.65 to 2.61, p=0.03), an extended duration of hospitalization (mean difference (MD) 2.88 days, 95% CI 2.09 to 3.67), an increased interval from surgery to the initiation of adjuvant chemotherapy (MD 4.44 days, 95% CI 2.41 to 6.07, p<0.0001), and a greater probability of undergoing reoperation (OR 4.7, 95% CI 1.91 to 11.55, p=0.0007). However, concerning the occurrence of specific post-operative complications such as anastomotic leakage (OR 0.97, 95% CI 0.33 to 2.84, p=0.95), pancreatic fistula (OR 3.25, 95% CI 0.63 to 16.7, p=0.16), abdominal abscess (OR 1.75, 95% CI 0.25 to 12.33, p=0.57), sepsis (OR 1.46, 95% CI 0.77 to 2.77, p=0.25), and thrombotic events (OR 1.82, 95% CI 0.93 to 3.57, p=0.08), no significant differences were observed between the two cohorts. CONCLUSION Splenectomy does not impact the overall survival and mortality of patients with ovarian cancer. Thus, it can be considered an acceptably safe procedure to obtain optimal cytoreduction. However, caution should be taken when selecting patients for splenectomy because it is associated with an increased incidence of overall post-operative complications, prolonged hospital stays, delayed initiation of adjuvant chemotherapy, and an increased probability of requiring subsequent surgical interventions.

Abstract
BACKGROUND The standard surgery for proximal advanced gastric cancer (PAGC) is total gastrectomy with D2 lymph node dissection (LND). Although prophylactic splenectomy for splenic hilar LND (No. 10) is not recommended due to any survival advantage, prophylactic LND (No. 10) without splenectomy remains controversial. Thus, we aimed to evaluate whether No. 10 LND is essential for patients' survival benefit in PAGC. METHODS We conducted a retrospective study of 1038 patients with PAGC who underwent total gastrectomy without splenectomy. After adjusting for confounders and propensity score matching (PSM), patients were grouped into Group 1 (D2 LND without splenic hilar LN; n = 288) or Group 2 (D2 LND with splenic hilar LN; n = 288). Variables between the two groups (5-year overall survival [OS] and disease-free survival [DFS]) were compared, as well as in patients with tumors located in the greater curvature and those with Borrmann type IV disease. RESULTS The 5-year OS and DFS rates after PSM were not significantly different between Groups 1 and 2 (57.3% vs. 62.1%, p = 0.300; 52.8% vs. 59.7%, p = 0.100, respectively). Furthermore, the 5-year OS and DFS rates in patients with greater curvature involvement (54.4% vs. 61.9%, p = 0.500; 50.0% vs. 57.6%, p = 0.400, respectively) and Borrmann type IV disease (23.8% vs. 38.6%, p = 0.400; 16.7% vs. 33.9%, p = 0.200, respectively) after PSM were also not significantly different between the two groups. CONCLUSIONS Prophylactic splenic hilar LND without splenectomy does not improve long-term survival in PAGC. Therefore, this procedure might not be essential for patients with PAGC as well greater curvature involvement and Borrmann type IV disease.

Abstract
Gastrectomy with lymph node (LN) dissection has been regarded as the standard surgery for gastric cancer (GC), however, the rational extent of lymphadenectomy remains controversial. Though gastrectomy with extended lymphadenectomy beyond D2 is classified as a non-standard gastrectomy, its clinical significance has been evaluated in many studies. Although hard evidence is lacking, D2 plus superior mesenteric vein (No. 14v) LN dissection is recommended when harbor metastasis to No. 6 nodes is suspected in the lower stomach, and dissection of splenic hilar (No. 10) LN can be performed for advanced GC invading the greater curvature of the upper stomach, and D2 plus posterior surface of the pancreatic head (No. 13) LN dissection may be an option in a potentially curative gastrectomy for cancer invading the duodenum. Prophylactic D2+ para-aortic nodal dissection (PAND) was not routinely recommended for advanced GC patients, but therapeutic D2 plus PAND may offer a chance of cure in selected patients, preoperative chemotherapy was considered as the standard treatment for GC with para-aortic node metastasis. There has been no consensus on the extent of lymphadenectomy for the adenocarcinoma of the esophagogastric junction (AEG) so far. The length of esophageal invasion can be used as a reference point for mediastinal LN metastases, and the distance from the esophagogastric junction to the distal end of the tumor is essential for determining the optimal extent of resection. The quality of lymphadenectomy may influence prognosis in GC patients. Both hospital volume and surgeon volume were important factors for the quality of radical gastrectomy. Centralization of GC surgery may be needed to improve prognosis.

Kinoshita T, Sato R, Akimoto E, Yoshida M, Harada J, Nishiguchi Y. Can laparoscopic spleen-preserving splenic hilar lymph node dissection replace prophylactic splenectomy for proximal advanced gastric cancers that invade the greater curvature? Eur J Surg Oncol 2020; 47:1466-1472. [PMID: 33267998 DOI: 10.1016/j.ejso.2020.11.133] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2020] [Revised: 11/05/2020] [Accepted: 11/20/2020] [Indexed: 11/27/2022] Open
Abstract
BACKGROUND AND OBJECTIVES Proximal advanced gastric cancer that invades the greater curvature is often treated by prophylactic splenectomy because of a risk for metastasis to the splenic hilar lymph node (station No.10). We evaluated whether laparoscopic spleen-preserving splenic hilar dissection (SPSHD) could be a better approach. METHODS We reviewed records of patients with proximal gastric cancer who underwent total gastrectomy with No.10 dissection between 2012 and 2018 using our in-house database set. We divided patients by whether they had received SPSHD or splenectomy, first to compare surgical outcomes, and subsequently to analyze survival outcomes among patients with tumors invading the greater curvature. RESULTS Of 145 patients enrolled in this study, 82 had SPSHDs and 63 had splenectomies. All SPSHDs were laparoscopic; 80% of splenectomies were laparotomic. Morbidity ≥ grade III was seen in 8.5% of the SPSHD group and 11.1% of the splenectomy group. The median number of retrieved No. 10 nodes was three in each group. In multivariable analysis, SPSHD was not an independent prognostic factor among patients whose tumors invaded the greater curvature (n = 73). Among propensity-matched cohorts (n = 25 each), 5-year relapse-free survival rates were 77.6% in the SPSHD group and 49.9% in the splenectomy group. CONCLUSION Laparoscopic SPSHD can potentially replace prophylactic splenectomy.

Abstract
BACKGROUND/AIM Prophylactic splenectomy has shown no inferiority for tumors not invading the greater curvature side. Despite this, the clinical impact of prophylactic splenectomy for proximal advanced gastric cancer is not clear. This review aimed to clarify the impact of splenectomy for advanced gastric cancer in the upper third of the stomach. MATERIALS AND METHODS A systematic review and meta-analysis were conducted based on PubMed and EMBASE databases. The following search terms were used: "gastric cancer" OR "splenectomy" OR upper third of the stomach" OR preservation of the spleen. RESULTS Out of 765 articles, 18 studies (combined n=6,341) were included in the analysis. Four randomized controlled trials (RCT) and eight retrospective studies suggested the benefits of spleen-preserving gastrectomy. Six retrospective studies showed no significant benefit of spleen-preserving gastrectomy. Prophylactic splenectomy showed a close association with a higher incidence of postoperative morbidity (pancreatic fistula and anastomotic leakage) with no concomitant improvement in overall survival. Prophylactic splenectomy should not be routinely performed and RCTs are necessary to confirm the impact of splenectomy for cN(+) at the splenic hilum tumors and tumors invading the greater curvature.

Therapeutic value of splenectomy to dissect splenic hilar lymph nodes for type 4 gastric cancer involving the greater curvature, compared with other types. Gastric Cancer 2020; 23:927-936. [PMID: 32307689 DOI: 10.1007/s10120-020-01072-6] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2019] [Accepted: 04/04/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND Whether splenectomy for splenic hilar lymph node (No. 10) dissection in type 4 gastric cancer involving the greater curvature is necessary is not established. Patients with type 4 gastric cancer often experience peritoneal relapse, despite curative surgery, and total gastrectomy with splenectomy is frequently associated with infectious complications. METHOD Patients with cT2-T4 gastric cancer in the upper or middle third of the stomach, or both, involving the greater curvature who underwent R0 total gastrectomy with splenectomy between 2006 and 2016 were selected. Clinicopathological findings, postoperative complications, the incidence of lymph node metastasis, and the therapeutic value index of each station were compared between type 4 and non-type 4 gastric cancer. RESULTS We enrolled 50 patients with type 4 and 60 with non-type 4. The former had a significantly higher proportion of the undifferentiated type and larger and deeper tumors. The overall incidence of Grade III or higher complications was 20.9%. The incidence of No. 10 metastasis was 26.0% in type 4 and 31.7% in non-type 4. Although the therapeutic value index of the No. 10 was 13.7 in type 4 and 15.0 in non-type 4, the index of type 4 ranked just below several peri-gastric stations and seventh, while that in non-type 4 ranked second. CONCLUSION Splenectomy for No. 10 dissection may be oncologically valid for type 4 gastric cancer involving the greater curvature. A safer procedure for No. 10 dissection should be established.

Abstract
BACKGROUND Laparoscopic distal gastrectomy for early gastric cancer has been widely accepted, but laparoscopic total gastrectomy has still not gained popularity because of technical difficulty and unsolved safety issue. We conducted a single-arm multicenter phase II clinical trial to evaluate the safety and the feasibility of laparoscopic total gastrectomy for clinical stage I proximal gastric cancer in terms of postoperative morbidity and mortality in Korea. The secondary endpoint of this trial was comparison of surgical outcomes among the groups that received different methods of esophagojejunostomy (EJ). METHODS The 160 patients of the full analysis set group were divided into three groups according to the method of EJ, the extracorporeal circular stapling group (EC; n = 45), the intracorporeal circular stapling group (IC; n = 64), and the intracorporeal linear stapling group (IL; n = 51). The clinicopathologic characteristics and the surgical outcomes were compared among these three groups. RESULTS There were no significant differences in the early complication rates among the three groups (26.7% vs. 18.8% vs. 17.6%, EC vs. IC vs. IL; p = 0.516). The length of mini-laparotomy incision was significantly longer in the EC group than in the IC or IL group. The anastomosis time was significantly shorter in the EC group than in the IL group. The time to first flatus was significantly shorter in the IL group than in the EC group. The long-term complication rate was not significantly different among the three groups (4.4% vs. 12.7% vs. 7.8%; EC vs. IC vs. IL; p = 0.359), however, the long-term incidence of EJ stenosis in IC group (10.9%) was significantly higher than in EC (0%) and IL (2.0%) groups (p = 0.020). CONCLUSIONS The extracorporeal circular stapling and the intracorporeal linear stapling were safe and feasible in laparoscopic total gastrectomy, however, intracorporeal circular stapling increased EJ stenosis.

Abstract
Background It remains controversial whether prophylactic No.10 lymph node clearance is necessary for gastric cancer. Thus, the present study aims to investigate the impact of prophylactic No.10 lymph node clearance on the perioperative complications and prognosis of upper and middle third gastric cancer. Methods A network meta-analysis to identify both direct and indirect evidence with respect to the comparison of gastrectomy alone (G-A), gastrectomy combination with splenectomy (G + S) and gastrectomy combination with spleen-preserving splenic hilar dissection (G + SPSHD) was conducted. We searched Medline, Embase, and the Cochrane Central Register of Controlled Trials (CENTRAL) for studies published before September 2018. Perioperative complications and overall survival were analyzed. Hazard ratios (HR) were extracted from the publications on the basis of reported values or were extracted from survival curves by established methods. Results Ten retrospective studies involving 2565 patients were included. In the direct comparison analyses, G-A showed comparable 5-year overall survival rate (HR: 1.1, 95%CI: 0.97–1.3) but lower total complication rate (OR: 0.37, 95%CI: 0.17–0.77) compared with G + S. Similarly, the 5-year overall survival rate between G + SPSHD and G + S was comparable (HR: 1.1, 95%CI: 0.92–1.4), while the total complication rate of G + SPSHD was lower than that of G + S (OR: 0.50, 95%CI: 0.28–0.88). In the indirect comparison analyses, both the 5-year overall survival rate (HR: 1.0, 95%CI: 0.78–1.3) and total complication rate (OR: 0.75, 95%CI: 0.29–1.9) were comparable between G-A and G + SPSHD. Conclusions Prophylactic No.10 lymph node clearance was not recommended for treatment of upper and middle third gastric cancer.

Abstract
Splenic hilar lymph node dissection has been the standard treatment for advanced proximal gastric cancer. Splenectomy is typically performed as part of this procedure. However, splenectomy has some disadvantages, such as increased risk of postoperative complications, especially pancreatic fistula. Moreover, patients who underwent splenectomy are vulnerable to potentially fatal infection caused by encapsulated bacteria. Furthermore, several studies have shown an association of splenectomy with cancer development and increased risk of thromboembolic events. Therefore, splenectomy should be avoided if it does not confer a distinct oncological advantage. Most studies that compared patients who underwent splenectomy and those who did not failed to demonstrate the efficacy of splenectomy. Based on the results of a randomized controlled trial conducted in Japan, prophylactic dissection with splenectomy is no longer recommended in patients with gastric cancer with no invasion of the greater curvature. However, patients with greater curvature invasion or those with remnant gastric cancer still need to undergo splenectomy to facilitate splenic hilar node dissection. Spleen-preserving splenic hilar node dissection is a new procedure that may help delink splenic hilar node dissection and splenectomy. In this review, we examine the evidence pertaining to the efficacy and disadvantages of splenectomy. We discuss the possibility of spleen-preserving surgery for prophylactic splenic hilar node dissection to overcome the disadvantages of splenectomy.

The Application of Spleen-Preserving Splenic Regional Laparoscopic Lymphadenectomy with Spleen Kept In Situ and Laparotomy with Spleen Lifted Out of the Abdomen for Locally Advanced Proximal Gastric Cancer: A Retrospective Study. Gastroenterol Res Pract 2019; 2019:4283183. [PMID: 31737066 PMCID: PMC6815632 DOI: 10.1155/2019/4283183] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/17/2018] [Accepted: 09/04/2019] [Indexed: 11/25/2022] Open
Abstract
Background and Purpose Findings whether laparoscopic lymphadenectomy with spleen kept in situ or laparotomy with spleen lifted out of the abdomen is more effective remain inconclusive. This study is aimed at comparing outcomes of spleen-preserving splenic regional laparoscopic lymphadenectomy with spleen kept in situ versus laparotomy with spleen lifted out of the abdomen for locally advanced proximal gastric cancer. Methods Data from patients with locally advanced proximal gastric cancer were collected from January 2011 to January 2014. A total of 246 patients were identified who received D2 radical total gastrectomy together with spleen-preserving splenic regional lymphadenectomy. Of those patients, 87 patients underwent laparoscopic splenic regional lymphadenectomy with spleen kept in situ (LSKS-SRLA) and 159 patients underwent laparotomy with spleen lifted out of the abdomen (LSLA-SRLA). Surgical outcomes and long-term outcomes were compared between the two groups. Results The total number of lymph node dissection, intraoperative blood loss volume, intraoperative injury cases, and postoperative complications had no statistically significant difference between the two groups. The number of splenic regional lymph node dissections was 3.90 ± 1.05 per case in the LSLA-SRLA group and 2.89 ± 1.04 in the LSKS-SRLA group. The operation time, length of the incision, and hospital days were shorter in the LSKS-SRLA group. The total recurrence and metastatic rates and 3-year cumulative survival rate had no statistically significant difference between the two groups. Conclusions Similar long-term outcomes were achieved in the LSKS-SRLA and LSLA-SRLA groups for locally advanced proximal gastric cancer. However, in the aspects of surgical time, length of incision, and postoperative recovery, the LSKS-SRLA group had obvious advantages.

Abstract
BACKGROUND The role of splenectomy for patients with gastric cancer still remains controversial. We performed this meta-analysis to evaluate the safety and long-term oncological outcomes of splenectomy for patients with gastric cancer. METHODS A systematic literature search was performed using PubMed, EMBASE, Cochrane Library, and Web of Science from January 1997 to October 2018. The results were analyzed according to predefined criteria. All statistical analyses were performed using RevMan 5.3 software. RESULTS In total, 16 studies with 4457 patients, including 3 randomized controlled trials (RCTs) and 13 non-randomized controlled trials (nRCTs), were analyzed. The meta-analysis showed the splenectomy group was associated with higher rates of overall postoperative complication, anastomosis leakage, abdominal abscess, and pancreatic fistula. Regarding long-term oncological outcomes, the splenectomy group showed lower 5-year overall survival (OS) and higher recurrence rates on subgroup analysis for the nRCTs. No significant difference was observed in the 5-year OS and recurrence rates between the two groups on subgroup analysis for the RCTs. CONCLUSIONS Splenectomy increases postoperative complications without clearly improving long-term prognosis.

Abstract
Purpose Splenic hilar lymph node dissection (LND) during total gastrectomy is regarded as the standard treatment for proximal advanced gastric cancer (AGC). This study aimed to investigate whether splenic hilar LND or D2 LND is essential for proximal AGC of pT2-4aN0M0 stage. Materials and Methods Data of curative total gastrectomies (n=370) performed from 2000 to 2010 for proximal AGC of pT2-4aN0 stage were retrospectively reviewed. Clinicopathological characteristics and long-term outcomes were compared using propensity score matching between patients who underwent splenectomy (n=43) and those who did not (n=327) and between patients who underwent D2 LND (n=122) and those who underwent D1+ LND (n=248). Results Tumors of larger size and a more advanced T stage and significantly lower overall and relapse-free survival (P<0.001) were observed in the splenectomy group than in the 2 spleen-preserving groups. Before propensity score matching, worse overall and relapse-free survival (P<0.001) was observed in the splenectomy group than in the non-splenectomy group. After matching, although the overall survival became similar (P=0.123), relapse-free survival was worse in the splenectomy group (P=0.021). Compared with D1+ LND, D2 LND had no positive impact on the overall (P=0.619) and relapse-free survival (P=0.112) after propensity score matching. Conclusions Splenic hilar LND with or without splenectomy may not have an oncological benefit for patients with pathological AGC with no LN metastasis.

Abstract
As radical gastrectomy with lymph node dissection is currently the best strategy to cure gastric cancer, the role of the surgeon remains quite important in conquering it. Dr. Sung Hoon Noh, a surgeon and surgical oncologist specializing in gastric cancer, has treated gastric cancer for 30 years and has conducted over 10000 cases of gastrectomy for gastric cancer. He first adapted an electrocautery device into gastric cancer surgery and has led standardization of surgical procedures, including spleen preserving gastrectomy. His procedures based on patient-oriented insights have become the basis of the concept of enhanced recovery after surgery. He has also contributed to improving patient's survival through adoption of a multidisciplinary approach: he proved the benefit of adjuvant chemotherapy after radical D2 gastrectomy for stage II/III gastric cancer in clinical trials, updating treatment guidelines throughout the world. Dr. Noh also opened the era of precision medicine for treating gastric cancer, as he developed and validated a mRNA expression based algorithm to predict prognosis and response to chemotherapy. This article reviews his contribution and long history of service in the field of gastric cancer. The perspectives of this master surgeon, based on his profound experience and insights, will outline directions for integrative multidisciplinary health care and how can surgeons prepare for the future.

Abstract
In this article, the current state of laparoscopic total gastrectomy (LTG) was reviewed, focusing on lymph node dissection and reconstruction. Lymph node dissection in LTG is technically similar to that in laparoscopic distal gastrectomy for early gastric cancer; however, LTG for advanced gastric cancer requires extended lymph node dissections including splenic hilar lymph nodes. Although a recent randomized controlled trial clearly indicated no survival benefit in prophylactic splenectomy for lymph node dissection at the splenic hilum, some patients may receive prognostic benefit from adequate splenic hilar lymph node dissection. Considering reconstruction, there are two major esophagojejunostomy (EJS) techniques, using a circular stapler (CS) or using a linear stapler (LS). A few studies have shown that the LS method has fewer complications; however, almost all studies have reported that morbidity (such as anastomotic leakage and stricture) is not significantly different for the two methods. As for CS, we grouped various studies addressing complications in LTG into categories according to the insertion procedure of the anvil and the insertion site in the abdominal wall for the CS. We compared the rate of complications, particularly for leakage and stricture. The rate of anastomotic leakage and stricture was the lowest when inserting the CS from the upper left abdomen and was significantly the highest when inserting the CS from the midline umbilical. Scrupulous attention to EJS techniques is required by surgeons with a clear understanding of the advantages and disadvantages of each anastomotic device and approach.

Abstract
BACKGROUND With improved short-term surgical outcomes, laparoscopic distal gastrectomy has rapidly gained popularity. However, the safety and feasibility of laparoscopic total gastrectomy (LTG) has not yet been proven due to the difficulty of the technique. This single-arm prospective multi-center study was conducted to evaluate the use of LTG for clinical stage I gastric cancer. METHODS Between October 2012 and January 2014, 170 patients with pathologically proven, clinical stage I gastric adenocarcinoma located at the proximal stomach were enrolled. Twenty-two experienced surgeons from 19 institutions participated in this clinical trial. The primary end point was the incidence of postoperative morbidity and mortality at postoperative 30 days. The severity of postoperative complications was categorized according to Clavien-Dindo classification, and the incidence of postoperative morbidity and mortality was compared with that in a historical control. RESULTS Of the enrolled patients, 160 met criteria for inclusion in the full analysis set. Postoperative morbidity and mortality rates reached 20.6% (33/160) and 0.6% (1/160), respectively. Fifteen patients (9.4%) had grade III or higher complications, and three reoperations (1.9%) were performed. The incidence of morbidity after LTG in this trial did not significantly differ from that reported in a previous study for open total gastrectomy (18%). CONCLUSIONS LTG performed by experienced surgeons showed acceptable postoperative morbidity and mortality for patients with clinical stage I gastric cancer.

Abstract
BACKGROUND Lymph nodes (LNs) at the splenic hilum (no. 10) are treated as regional LNs in proximal gastric carcinoma. However, patients with no.10 LN metastasis show a poor prognosis after curative surgery. This study aimed to investigate the prognostic impact of no.10 LN metastasis in proximal gastric carcinoma. METHODS We retrospective reviewed 665 proximal gastric carcinoma patients who underwent total gastrectomy and D2 LN dissection. Clinicopathological features were compared between patients with and without no.10 LN metastasis. The prognostic value of no.10 LN metastasis was examined using Cox prognostic model. RESULTS There were 63 (9.5%) patients with no. 10 LN metastasis. No. 10 LN metastasis only existed in stage III/IV, and was significantly associated with greater curvature/circumferential tumor location, larger tumor size, B4 gross type, undifferentiated histology, lymphovascular invasion. The 5-year survival of no.10 LN metastasis group was 26%, which was significantly lower than those without no.10 LN metastasis (79%, p < 0.001). Patients with no. 10 LN metastasis also showed a significantly worse survival than those without in each tumor stage (stage III = 45% vs. 66%, p = 0.044, stage IV = 13% vs. 33%, p = 0.024). In the multivariate cox model, no.10 LN metastasis was an independent poor prognostic factor when adjusting for TNM stage and other prognostic factors. CONCLUSION The prognosis of no.10 LN metastasis is as poor as that of distant metastasis. This suggests that no. 10 LN should rather be considered as non-regional LNs in the treatment of proximal gastric carcinoma.

Abstract
BACKGROUNDS Patients with proximal gastric carcinoma undergo total gastrectomy with concomitant splenectomy to ensure the complete removal of splenic hilar lymph nodes. However, the impact of splenectomy on survival remains uncertain. This study aimed to investigate the impact of splenectomy on survival among patients with gastric carcinoma. METHODS Of 1074 patients who underwent total gastrectomy for proximal gastric carcinoma between 2006 and 2014, 229 patients underwent concomitant splenectomy or pancreaticosplenectomy during surgery. We investigated the prognostic impact of splenectomy using a regression and propensity score matched model. RESULTS The splenectomy and non-splenectomy groups differed in many baseline characteristics, including tumor stage, and had respective crude 5-year survival rates of 55% and 81% (p <0.001). In a multivariate analysis adjusted for TNM stage and other prognostic factors, splenectomy was an independent poor prognostic factor for overall survival (hazard ratio [HR] = 1.67, 95% confidence interval [CI] = 1.11-2.51) and disease-free survival (HR = 1.61, 95% CI = 1.24-2.10). A survival evaluation stratified by TNM stage showed that splenectomy adversely affected survival among patients with stage III, but not stage I, II, and IV disease. In the propensity score-matched sample, splenectomy group also showed significantly worse overall survival (5-year, 65% vs. 79%, p = 0.010) and disease-free survival (5-year, 55% vs. 72%, p = 0.025) and was an independent poor prognostic factor in a multivariate analysis adjusting TNM stage and other prognostic factors. CONCLUSIONS Splenectomy adversely affects survival, particularly among patients with stage III gastric carcinoma, and should be avoided unless there is direct invasion to the splenic hilum.

Abstract
PURPOSE This study is a systematic review and meta-analysis compare the short- and long-term outcomes of splenectomy (SP) versus splenic preservation (NSP) in radical gastric cancer surgery. METHODS A comprehensive search of PubMed, Embase, Cochrane Library and Web of Knowledge was performed. Evaluation of short- and long-term outcomes was collected and analyzed by a fixed or random effects model, according to the heterogeneity using RevMan 5.2 software. RESULTS A total of 5431 gastric cancer patients who underwent radical surgery (1706 with SP and 3725 with NSP) were reviewed in 11 studies included in this study. Compared with NSP, SP was significantly associated with higher rate of overall postoperative complication and increased incidence of pulmonary complications, abdominal abscess and pancreas complications. No statistical difference was observed regarding mortality, wound infection, anastomotic leakage and postoperative 5-year overall survival. CONCLUSION There was no difference in long-term oncological outcome but remarkably poorer short-term outcomes in SP group than NSP group. Therefore, SP seems unnecessary in radical gastric cancer surgery. However, well-designed, multicenter, prospective, randomized controlled trials are warranted for further validation.

Is it necessary to dissect the posterior lymph nodes along the splenic vessels during total gastrectomy with D2 lymphadenectomy for advanced gastric cancer? Eur J Surg Oncol 2017; 43:2357-2365. [PMID: 29032923 DOI: 10.1016/j.ejso.2017.09.008] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2017] [Revised: 04/11/2017] [Accepted: 09/06/2017] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND D2 lymphadenectomy including No.10 lymph nodes (LNs) is the standard procedure for treating advanced gastric cancer (AGC) via total gastrectomy. However, there was no research focusing on the posterior LN dissection along the splenic vessels (No.10p LNs). This study is performed to assess the effect of dissecting No.10p LNs. METHODS We analyzed 404 consecutive gastric cancer patients who underwent laparoscopic total gastrectomy (LTG) with D2 lymphadenectomy. There were 68 patients with No.10p LN dissection (No.10p group), and 336 patients without No.10p LN dissection (nNo.10p group). The surgical outcomes are compared. RESULTS No.10p LN dissection was preferentially performed in patients who were younger and had a lower BMI, concentrated and single-branched type of splenic artery, and pancreatic tail near the lower pole of the spleen. The time for No.10 LN dissection and the number of No.10 LNs were greater in the No.10p group than in the nNo.10p group. There was no No.10p LNs metastasis, and the numbers of positive No.10 LNs were similar between the two groups. The morbidity and mortality rates of the No.10p group were comparable to those of the nNo.10p group. The overall survival (OS) rates of the two groups were not significantly different (P > 0.05). CONCLUSIONS Although No.10p LN dissection might retrieve more No.10 LNs, operation times were longer, and the number of positive No.10 LNs and the OS rate were not improved. It might be no necessary to dissect No.10p LNs during total gastrectomy with D2 lymphadenectomy for AGC.

Abstract
Background Impact of splenic hilar LN dissection during total gastrectomy for proximal advanced gastric cancer is controversial. The objective of this study was to assess the impact on prognosis of splenic hilar lymph node(LN) metastasis compared to that of metastasis to other regional LN groups. Study Design Patients who underwent total gastrectomy with D2 LN dissection from 2000 to 2010 were reviewed retrospectively. The clinicopathologic characteristics and long-term results of patients with splenic hilar LN metastasis were compared to those of patients with only metastasis to other extraperigastric LNs (stations #8a, #9, #11, or #12a). To investigate the survival benefit of performing splenic hilar LN dissection, the estimated therapeutic index for the procedure was calculated by multiplying the incidence of metastases in the hilar region by the survival rates for individuals with nodal involvement in that region. Results Of 602 patients, 87(14.5%) had hilar LN metastasis. The 5-year overall and relapse-free survival rates for patients with hilar LN metastasis were 24.1% and 12.1%, respectively. These rates were similar to those for patients with metastasis to other extraperigastric LNs (P > 0.05), with similar recurrence patterns. Overall survival in the hilar LN metastasis group was better than that for patients with distant metastasis(P < 0.05). The estimated therapeutic index of splenic hilar LN dissection was 3.5, which was similar to index values for LN dissection at other extraperigastric LNs. Conclusions Dissection of splenic hilar LNs during total gastrectomy for advanced gastric cancer allows for a prognosis similar to that achieved with dissection of extraperigastric LNs.

Abstract
Gastric cancer is one of the leading causes of cancer-related deaths worldwide. Despite the high disease prevalence, gastric cancer research has not gained much attention. Recently, genome-scale technology has made it possible to explore the characteristics of gastric cancer at the molecular level. Accordingly, gastric cancer can be classified into molecular subtypes that convey more detailed information of tumor than histopathological characteristics, and these subtypes are associated with clinical outcomes. Furthermore, this molecular knowledge helps to identify new actionable targets and develop novel therapeutic strategies. To advance the concept of precision patient care in the clinic, patient-derived xenograft (PDX) models have recently been developed. PDX models not only represent histology and genomic features, but also predict responsiveness to investigational drugs in patient tumors. Molecularly curated PDX cohorts will be instrumental in hypothesis generation, biomarker discovery, and drug screening and testing in proof-of-concept preclinical trials for precision therapy. In the era of precision medicine, molecularly tailored therapeutic strategies should be individualized for cancer patients. To improve the overall clinical outcome, a multimodal approach is indispensable for advanced cancer patients. Careful, oncological principle-based surgery, combined with a molecularly guided multidisciplinary approach, will open new horizons in surgical oncology.

Abstract
Laparoscopic distal gastrectomy has recently become accepted as a surgical option for early gastric cancer in the distal stomach, but laparoscopic total gastrectomy (LTG) has not become widespread because of technical difficulties of esophagojejunal anastomosis and splenic hilar lymphadenectomy. Splenic hilar lymphadenectomy should be employed in the treatment of advanced proximal gastric cancer to complete D2 dissection, but laparoscopically it is technically difficult even for skilled surgeons. Based on the evidence that prophylactic combined resection of spleen in total gastrectomy increased the risk of postoperative morbidity with no survival impact, surgeons have preferred laparoscopic spleen-preserving splenic hilar lymphadenectomy (LSPL) for advanced tumors without metastasis to splenic hilar nodes or invasion to the greater curvature of the stomach, and reports with LSPL have been increasing rather than LTG with splenectomy. In this paper, recent reports with laparoscopic splenic hilar lymphadenectomy were reviewed.

Abstract
Gastric cancer imposes a global health burden. Although multimodal therapies have proven to benefit patients with advanced diseases after curative surgery, the prognosis of most advanced cancer patients still needs to be improved. Surgical extirpation is the mainstay of gastric cancer treatment. Indeed, without curative surgery, variations and combinations of chemotherapy and/or radiation cannot bring clinically meaningful success. Centered around D2 surgery, adjuvant and peri-operative multimodal therapies have improved survival in a certain group of gastric cancer patients. Moving toward a personalized cancer therapy era, molecular targeted strategies have been tested in clinical trials for gastric cancer. With some success and failures, we have learned valuable lessons regarding the biology of gastric cancer and the clinical relevance of biological therapies in addition to conventional treatments. Future treatment of gastric cancer will be shifted to molecularly tailored and genome information-based personalized therapy. Collaboration across disciplines and actively adopting emerging anti-cancer strategies, along with in-depth understanding of molecular and genetic underpinnings of tumor development and progression, are imperative to realizing personalized therapy for gastric cancer. Although many challenges remain to be overcome, we envision that the era of precision cancer medicine for gastric cancer has already arrived and anticipate that current knowledge and discoveries will be transformed into near-future clinical practice for managing gastric cancer patients.

Abstract
To compare the effectiveness and safety of in-vivo dissection procedure of No. 10 lymph nodes with those of ex-vivo dissection procedure for gastric cancer patients with total gastrectomy.Patients were divided into in-vivo group and ex-vivo group according to whether the dissection of No. 10 lymph nodes were performed after the mobilization of the pancreas and spleen, and migration out from peritoneal cavity. Clinicopathologic characteristics, overall survival, morbidity, and mortality were compared between the 2 groups.There were 148 patients in in-vivo group, while 30 in ex-vivo group. The baselines between the 2 groups were almost comparable. The metastatic ratio of No. 10 lymph nodes were 6.1% and 10.0% (P = 0.435) and the metastatic degree were 7.9% and 13.6% (P = 0.158) for in-vivo group and ex-vivo group, respectively. There was no difference in morbidity or mortality between the 2 groups. The number of total harvested lymph nodes and No. 10 lymph nodes increased significantly in ex-vivo group at the cost of prolonged operation time. The estimated overall survival rates for patients in in-vivo group and ex-vivo group were (3-year: 52.0% vs 61.8%) and (5-year: 45.3% vs 49.5%), respectively, without statistical significance. Further multivariable analysis had showed that the procedure of No. 10 lymphadenectomy was not a significant independent prognostic factor.Both in-vivo and ex-vivo dissection of No. 10 lymph nodes could be performed safely. It seems that ex-vivo dissection of No. 10 lymph nodes can result in a higher effective dissection at the cost of the operation time, but the overall survival rates were not statistically significant between the 2 groups, which should be confirmed further in a well-designed randomized controlled trial.

Abstract
BACKGROUND Laparoscopic distal gastrectomy (LDG) is a routinely performed procedure. However, clinical expertise in laparoscopic total gastrectomy (LTG) is insufficient, and it is only performed at specialized institutions. This study aimed to identify critical factors associated with complications after laparoscopic gastrectomy (LG), particularly LTG. METHODS A large-scale database was used to identify critical factors influencing the early outcomes of LTG. Of 1248 patients with resectable gastric cancer who underwent LG, 259 underwent LTG. Predictive risk factors were determined by analyzing relationships between clinical characteristics and postoperative complications. Major complications after LTG were analyzed in detail. RESULTS Multivariate analysis of all LG procedures revealed LTG as a risk factor for complications. Morbidity in the LDG and LTG groups was 6.2 % (52 of 835 patients) and 22.4 % (58 of 259 patients), respectively. Major post-LTG complications included anastomotic leakages and pancreatic fistulae. The rate of anastomotic leakage was significantly higher in the LTG group (5.0 %) than in the LDG group (1.2 %); however, it showed a tendency to decrease in more recent cases. Pancreatic fistulae occurred frequently after LTG with D2 lymphadenectomy (LTG-D2), particularly in cases of concomitant pancreatosplenectomy. Obesity was also associated with pancreatic fistula formation after LTG with pancreatosplenectomy. CONCLUSIONS Compared with LDG, LTG is a developing procedure. Advances in the surgical techniques associated with the LTG procedure will improve the short-term outcomes of esophagojejunostomy. With regard to LTG-D2, establishing optimal and safe #10 node dissection is one of the most urgent issues. Pancreatic fistula after LTG with pancreatosplenectomy must be investigated in the future.

Abstract
Oncological advisability of spleen removal during surgical treatment of gastric cancer is arguable at present time. It is presented technique of spleen-preserving D2-lymphodissection used for gastric body and proximal part cancer which was applied in 155 patients. Control group included 197 patients who underwent gastrectomy with splenectomy. Spleen-preserving D2-lymphodissection increased duration of surgery but decreased frequency of subdiaphragmatic abscess and pancreatic fistulas and duration of hospital stay. 5-years survival (Kaplan-Meier) was 59% in main group, in control group - 55% (p>0.05). We consider that spleen-preserving D2-lymphodissection is radical and safe surgical method for locally advanced cancer of gastric body and proximal part.

Abstract
This study was aimed to evaluate the survival benefit and safety of No. 10 lymphadenectomy for gastric cancer patients with total gastrectomy.Splenic hilar lymph nodes (LNs) are required to be dissected in total gastrectomy with D2 lymphadenectomy. However, there has still not been a consensus in aspects of survival and safety on No. 10 LN resection.From January 2006 to December 2011, 453 patients undergoing total gastrectomy for gastric cancer were retrospectively analyzed. Patients were grouped according to No. 10 lymphadenectomy (10D+/10D-). Clinicopathologic characteristics were compared between the 2 groups. These patients had undergone a follow-up until January 2014. The overall survival, morbidity, and mortality rate were analyzed. Subgroup analyses which were stratified by the sex, age, tumor location, lymphadenectomy extent, curative degree, differentiation, tumor size, and TNM staging (ie, stages of tumor) were performed.There were 220 patients in 10D+ group, whereas 233 in 10D- group. In terms of prognosis, the baseline features between the 2 groups were almost comparable. The incidence of No. 10 LN metastasis was 11.82%. There was no difference in morbidity and mortality between the 2 groups. Significantly more LNs were harvested from patients in 10D+ group (P = 0.000). The estimated overall 5-year survival rates were 46.44% and 37.43% in 10D+ group and 10D- group respectively, which is not statistically significant (P = 0.3288). Although no statistical significance was found in the estimated 5-year survival rate, these data were obviously higher in patients with age >60 years, Siewert II/ III tumors, N1 status, or IIIa/IIIc stages when No. 10 lymphadenectomies were performed.Although the differences were obvious, the 5-year survival rates between the 2 groups did not reach statistical significances, which was probably caused by too small patient samples. High-quality studies with larger sample sizes are needed before stronger statement can be done. Until then, the No. 10 LNs' resection might be recommended in total gastrectomy with D2 lymphadenectomy with an acceptable incidence of complications.

[PMID: 25170225 PMCID: PMC4145779 DOI: 10.3748/wjg.v20.i32.11376] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2014] [Revised: 04/12/2014] [Accepted: 07/25/2014] [Indexed: 02/06/2023] Open
Abstract
AIM: To evaluate the feasibility and short-term efficacy of laparoscopic spleen-preserving splenic hilar (No. 10) lymphadenectomy to treat advanced upper gastric cancer (AUGC).
METHODS: Between January and December 2012, 108 laparoscopic spleen-preserving No. 10 lymphadenectomy along with total gastrectomy with routine D2 lymphadenectomy were performed consecutively at our hospital to treat clinical T2-3 (cT2-3) upper gastric cancers. The preoperative clinical T stage was cT2 in 36 patients and cT3 in 72 patients. A prospectively designed database tracked the 108 patients, including the completeness of their medical records and the adequacy of follow-up. Patient clinicopathological characteristics, intraoperative and postoperative surgical outcomes, morbidity and mortality, lymph node (LN) dissection, and postoperative follow-up were analysed retrospectively.
RESULTS: Laparoscopic spleen-preserving No. 10 lymphadenectomy was successful in all 108 patients. The mean operation time was 169.3 ± 27.1 min, and the mean No. 10 lymphadenectomy time was 20.0 ± 5.7 min. The mean total blood loss was 46.2 ± 11.3 mL, and the mean blood loss from No. 10 lymphadenectomy was 14.3 ± 3.8 mL. The mean postoperative hospital stay was 11.9 ± 6.0 d. The intraoperative and postoperative morbidity rates were 3.7% and 12.0%, respectively; however, there was no postoperative mortality. A mean of 44.4 ± 17.6 LNs were retrieved from each specimen, including 3.0 ± 2.4 No. 10 LNs. Three patients (2.8%) with cT3 cancer had LN metastasis of the splenic hilus, including two patients with pathological T3 (pT3) and one patient with pathological T4a (pT4a) tumours, all located in the greater curvature. No splenic hilar LNs metastasis was evident in the patients with pT1 and pT2 tumours. At a median follow-up time of 18 mo (range, 12 to 23 mo), all patients were alive and none had experienced recurrent or metastatic disease.
CONCLUSION: Laparoscopic spleen-preserving No. 10 lymphadenectomy is feasible and effective to treat AUGC. Routine No. 10 lymphadenectomy may be unnecessary for AUGC without serosa invasion, unless T3 tumours are located in the greater curvature.

Chin J Cancer Res 2014; 26:231-3. [PMID: 25035646 DOI: 10.3978/j.issn.1000-9604.2014.06.15] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2014] [Accepted: 06/13/2014] [Indexed: 11/14/2022] Open
Abstract
Qualified radical gastrectomy with lymph node dissection is very important to the prognosis of patients with gastric cancer. Now D2 lymph node dissection is standard procedure for gastric cancer surgery, and spleen hilar lymph node dissection is mandatory for gastric cancer in upper body. Because the anatomy of vessels in this area is very complicated, D2 lymph node dissection is technical challenging not only for open gastrectomy but also for laparoscopic one. Adapting a new technique is important to all surgeons, but we surgeons should always consider a patient's safety as the most important factor during surgery and that efforts should be based on scientific rationale with oncologic principles. I hope that the recent report by Huang et al. about laparoscopic spleen preserving hilar lymph node dissection would be helpful to young surgeons who will perform laparoscpic total gastrectomy for gastric cancer.

Is concomitant splenectomy beneficial for the long-term survival of patients with gastric cancer undergoing curative gastrectomy? A single-institution study. World J Surg Oncol 2014; 12:193. [PMID: 24969079 PMCID: PMC4226942 DOI: 10.1186/1477-7819-12-193] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2013] [Accepted: 08/07/2013] [Indexed: 01/01/2023] Open
Abstract
BACKGROUND Curative resection is the treatment of choice for gastric cancer, but it is unclear whether gastrectomy should also include splenectomy. We retrospectively analyzed long-term survival in patients in our hospital who underwent gastrectomy plus splenectomy (G+S) or gastrectomy alone (G-A) for gastric cancer. METHODS We identified 214 patients who underwent surgery with curative intent between 1980 and 2003. Of these, 100 underwent G+S, and 114 underwent G-A. The primary endpoint was 5-year overall survival (OS). RESULTS Median follow-up was 18 months in patients who underwent G+S, and 26.5 months in patients who underwent G-A. The 5-year OS rate was significantly higher in patients who underwent G-A (33.8%; 95% CI 24.2 to 43.4%) than in those who underwent G+S (28.8%; 95% CI 19.6 to 38.0%) (log-rank test, P=0.013). CONCLUSIONS Splenectomy does not benefit patients undergoing gastrectomy for gastric cancer. Routine splenectomy should be abandoned in patients undergoing radical resections for gastric cancer.

Abstract
BACKGROUND Robotic systems recently have been introduced to overcome technical limitations of conventional laparoscopic surgery, especially for complex procedures. Laparoscopic spleen-preserving total gastrectomy with D2 lymph node (LN) dissection (LTGD2) is one of the most complicated procedures. We hypothesized that robotic LN dissection would be more thorough and accurate. We compared robotic spleen-preserving total gastrectomy with D2 LN dissection (RTGD2) with LTGD2 to investigate the impact of robotics. METHODS Clinicopathologic characteristics and short-term and long-term outcomes of RTGD2 (n = 51) versus LTGD2 (n = 58) in gastric adenocarcinoma patients were extracted from a prospectively designed database and analyzed retrospectively. RESULTS There was no difference of patients' characteristics between groups. Mean operation time of RTGD2 was longer than LTGD2 (p < 0.001), and no differences in tumor histology, size, location, and TNM stage were seen. Total retrieved LNs from RTGD2 was similar to LTGD2 (mean 47.2 vs. 42.8, respectively), as were retrieved LNs at splenic hilum (1.3 vs. 0.8). However, mean numbers of retrieved LNs along the splenic artery from RTGD2 was higher than LTGD2 (2.3 vs. 1.0, respectively; p = 0.013), as was also the case at the splenic hilum and artery (3.6 vs. 1.9, p = 0.014). Postoperative complication (16 vs. 22 %, p = 0.374) and overall and disease-free survival between the two groups were not significantly different (p = 0.767 and p = 0.666, respectively). CONCLUSIONS Robotic spleen-preserving total gastrectomy with D2 LN dissection is feasible. Operation time and retrieved total LNs and splenic hilar LNs in the robotic procedure are acceptable.

Abstract
BACKGROUND The overall prognosis and survival of patients with advanced gastric cancer are generally poor. Extended lymphadenectomy is recommended for patients with advanced gastric cancer; however, splenectomy and distal pancreatectomy performed with an extended lymph node dissection may be associated with increased morbidity and mortality. METHOD Electronic literature searches were conducted using Medline, Embase, and the Cochrane Central Register of Controlled Trials from 1 January 1998 to 31 December 2009. Studies on gastric carcinoma investigating extended lymphadenectomy with splenectomy and/or pancreaticosplenectomy that reported data on surgical outcomes or survival were selected. RESULTS Forty studies were included in this review. Decreased complication rates were demonstrated with spleen preservation in two prospective studies and three retrospective studies, and with pancreas preservation in five retrospective studies. No randomized controlled trial showed survival benefit or detriment for preservation of spleen or pancreas in extended lymphadenectomy. Improved survival was demonstrated with spleen preservation in two prospective and eight retrospective studies, and with pancreas preservation in one prospective and four retrospective studies. CONCLUSIONS Preservation of the spleen and pancreas during extended lymphadenectomy for gastric cancer decreases complications with no clear evidence of improvement or detriment to overall survival.

Abstract
Purpose When performing a laparoscopic assisted gastrectomy, a function-preserving gastrectomy is performed depending on the location of the primary gastric cancer. This study examined the incidence of lymph node metastasis by the lymph node station number by tumor location to determine the optimal extent of the lymph node dissection. Materials and Methods The subjects consisted of 1,510 patients diagnosed with gastric cancer who underwent a gastrectomy between 1996 and 2005. The patients were divided into three groups: upper, middle and lower third, depending on the location of the primary tumor. The lymph node metastasis patterns were analyzed in the total and early gastric cancer patients. Results In all patients, lymph node station numbers 1, 2, 3, 7, 10 and 11 metastases were dominant in the cancer originating in the upper third, whereas station numbers 4, 5, 6 and 8 were dominant in the lower third. In early gastric cancer patients, the station number of lymph nodes with a metastasis did not show a significant difference in stage pT1a disease. On the other hand, a metastasis in lymph node station number 6 was dominant in stage pT1b disease that originated in the lower third of the stomach. Conclusions When performing a laparoscopic-assisted gastrectomy for early gastric cancer, a limited lymphadenectomy is considered adequate during a function-preserving gastrectomy in mucosal (T1a) cancer. On the other hand, for submucosal (T1b) cancer, a number 6 node dissection should be performed when performing a pylorus preserving gastrectomy.

Abstract
AIM: To investigate the pattern of lymph node metastasis in advanced proximal gastric cancer to guide the extent of stomach resection (proximal or total gastrectomy) and to evaluate the necessity of splenectomy.
METHODS: The clinicopathological data for 86 patients with advanced proximal gastric cancer who underwent radical gastrectomy at our hospital from January 1989 to September 2010 were retrospectively analyzed. The number and size of detected lymph nodes were recorded. The total and average number of detected lymph nodes, total rate of lymph node metastasis, and metastasis rates of Nos. 1-16 lymph nodes were calculated.
RESULTS: A total of 4 756 (30-157) lymph nodes were detected in the surgical specimens from 86 patients with advanced proximal gastric cancer, and the average number of detected lymph nodes was 55.30 ± 20.23. Of 4 756 detected lymph nodes, 3 859 (81.14%) had a size of ≤5 mm. Seventy of 86 cases had lymph node metastasis, and the total rate of lymph node metastasis was 81.40%. Of 912 metastatic lymph nodes, 556 (60.96%) had a size of ≤5 mm. The metastasis rates of Nos. 1-4 and 7-9 lymph nodes (39.53%-80.23%) were higher than those of Nos. 12-15 (0.00%-2.33%). The metastasis rates of Nos 5, 6, 10, 11 and 16 lymph nodes were 22.09%, 15.12%, 33.72%, 18.60% and 15.12%, respectively.
CONCLUSION: Analysis of the pattern of lymph node metastasis in proximal advanced gastric cancer has an appreciable value in guiding lymphadenectomy. Total gastrectomy plus splenectomy is a feasible radical surgery for proximal advanced gastric cancer because of the requirement of resection of Nos. 5-6 and Nos. 10-11 lymph nodes.

Abstract
Gastric cancer is the most common malignancy and the incidence is steadily increasing in Korea. The principal treatment modality for gastric cancer is surgical extirpation of tumor along with draining lymph nodes. Gastrectomy with D2 lymph node dissection has been well established as a standard of surgery and improved the survival of gastric cancer patients. Recently, technological advances are drastically reshaping the landscape of surgical treatment of gastric cancer. One of the most notable trends is that minimal access surgery becomes dominating the treatment of early stage diseases. For advanced diseases, the standard access surgery is considered a reference treatment. Although there is a pilot study underway to evaluate the feasibility of the application of minimal access surgery to advanced gastric cancer (AGC), the evidence for oncological safety is not yet provided sufficiently. Based on the recent randomized controlled trials, the extent of surgery for AGC has re-defined as para-aortic lymph node dissection dose not add any survival benefit while increasing surgery-related morbidities. In addition, it is now accepted as a standard operation omitting unnecessary procedures such as splenectomy and/or distal pancreatectomy for prophylactic lymph node dissection. Conceptual and technical innovation has contributed to decreasing morbidity and mortality without impairing oncological safety. All these recent advances in the field of gastric cancer surgery would be concluded in maximizing therapeutic index for gastric cancer while improving quality of life.

Abstract
PURPOSE We sought to examine how splenectomy as part of up-front cytoreductive surgery in ovarian cancer influences the postoperative course and affects survival. METHODS We reviewed cases of ovarian cancer diagnosed at Massachusetts General Hospital from 1994 to 2008 and found 44 patients who had a splenectomy as part of their up-front cytoreductive surgery. These were compared to 171 patients who did not undergo splenectomy. We evaluated age at diagnosis, estimated blood loss, percentage of patients whose disease was optimally cytoreduced (<1 cm), reason for splenectomy (oncologic vs. surgical), length of stay, time to first chemotherapy treatment, and survival. RESULTS In the splenectomy cohort, the mean age at diagnosis was 64 (44-83) years. A total of 37 of 44 (84%) patients were optimally cytoreduced. Mean estimated blood loss was 1326 ml. The purpose of splenectomy was to accomplish an optimal cytoreduction (oncologic) in 82% of cases. Median length of stay was 13 (6-76) days. Median time to first chemotherapy was 13.5 (5-54) days. The median disease-free interval and overall survival of the splenectomy cohort were 8 and 30 months, respectively. The median overall survival for patients whose disease was optimally cytoreduced in the splenectomy cohort compared to the no-splenectomy group was 30 and 45 months (P < 0.045), respectively. CONCLUSIONS The addition of splenectomy to up-front cytoreductive surgery was feasible and safe. However, it appears to carry with it a shortened survival that is unrelated to postoperative morbidity. Our data raise the questions that splenectomy is needed for optimal cytoreduction in more biologically aggressive disease and that splenectomy may be an independent prognostic factor related to depressed immune function.

Abstract
BACKGROUND Although studies comparing the surgical treatment of gastric carcinoma in Japan and Western industrialized countries have revealed differing survival rates, no studies to date have been performed comparing Western and Eastern Europe. This study aimed to compare demographics and surgical practice as well as the related prognostic impact on gastric cancer patients treated in Poland and Germany. METHODS This retrospective study included gastric cancer patients treated between 1999 and 2004 by surgical departments in Gdansk (Poland) and Cologne (Germany). Univariate and multivariate analyses of demographic, histopathological, surgical, and prognostic data were performed. RESULTS Included were 117 patients from Gdansk and 130 patients from Cologne. The Cologne patients showed higher incidence rates of serious comorbidity, pT1 cancer, and distant metastasis than those from Gdansk. Indications for and frequency of selected surgical procedures differed significantly. D2-lymphadenectomy was performed in 89% of the Cologne patients, while D1-lymphadenectomy was done for 85% of the Gdansk patients. Univariate analysis yielded a 5-year survival rate of 28.3% for the Gdansk patients, and 40.3% for the Cologne patients (p = 0.056). Independent prognostic factors were pT category (p = 0.002), pN category (p < 0.001), pM category (p = 0.027), residual tumor (R) category (p = 0.004), age (p = 0.012), and number of resected lymph nodes (p = 0.005). CONCLUSIONS Significant differences of clinical and surgical parameters exist between gastric cancer patients treated in Poland and Germany. In addition to established independent prognostic factors, we found that survival improved with each additionally resected lymph node.

Abstract
AIM: To investigate the occurrence of postoperative complications of gastric cancer surgery, and analyze the potential causes of reoperation for early postoperative complications.
METHODS: A total of 1639 patients who underwent radical or palliative gastrectomies for gastric cancer were included in the study. The study endpoint was the analysis of postoperative complications in inpatients.
RESULTS: About 31% of patients had early postoperative complications, and complications of infection occurred most frequently. Intra-abdominal hemorrhage and anastomotic leak were the main causes of reoperation, which accounted for about 2.2%. Mortality was 11.1% in the reoperation group, but was only 0.8% in other patients. The duration of postoperative stay in hospital was significantly longer and the total expenditure was markedly higher in the patients who underwent reoperation (P < 0.001). There was no significant association of any available factors in this study with the high rate of reoperation.
CONCLUSION: Reoperation significantly increases the mortality rate and raises the burden of the surgical unit. More prospective studies are required to explore the potential risk factors.
