Dong YP, Cai FL, Wu ZZ, Wang PL, Yang Y, Guo SW, Zhao ZZ, Zhao FC, Liang H, Deng JY. Risk of station 12a lymph node metastasis in patients with lower-third gastric cancer. World J Gastrointest Surg 2021; 13:1390-1404. [PMID: 34950428 PMCID: PMC8649572 DOI: 10.4240/wjgs.v13.i11.1390] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/07/2021] [Revised: 07/06/2021] [Accepted: 10/25/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Controversy over the issue that No. 12a lymph node involvement is distant or regional metastasis remains, and the possible inclusion of 12a lymph nodes in D2 lymphadenectomy is unclear. As reported, gastric cancer (GC) located in the lower third is highly related to the metastasis of station 12a lymph nodes.
AIM To investigate whether the clinicopathological factors and metastasis status of other perigastric nodes can predict station 12a lymph node metastasis and evaluate the prognostic significance of station 12a lymph node dissection in patients with lower-third GC.
METHODS A total of 147 patients with lower-third GC who underwent D2 or D2+ lymphadenectomy, including station 12a lymph node dissection, were included in this retrospective study from June 2003 to March 2011. Survival prognoses were compared between patients with or without station 12a lymph node metastasis. Logistic regression analyses were used to clarify the association between station 12a lymph node metastasis and clinicopathological factors or metastasis status of other perigastric nodes. The metastasis status of each regional lymph node was evaluated to identify the possible predictors of station 12a lymph node metastasis.
RESULTS Metastasis to station 12a lymph nodes was observed in 18 patients with lower-third GC, but not in 129 patients. The incidence of station 12a lymph node involvement was reported as 12.2% in patients with lower-third GC. The overall survival of patients without station 12a lymph node metastasis was significantly better than that of patients with station 12a metastasis (P < 0.001), which could also be seen in patients with or without extranodal soft tissue invasion. Station 12a lymph node metastasis and extranodal soft tissue invasion were identified as independent predictors of poor prognosis in patients with lower-third GC. Advanced pN stage was defined as independent risk factor significantly correlated with station 12a lymph node positivity. Station 3 lymph node staus was also proven to be significantly correlated with station 12a lymph node involvement.
CONCLUSION Metastasis of station 12a lymph nodes could be considered an independent prognosis factor for patients with lower-third GC. The dissection of station 12a lymph nodes may not be ignored in D2 or D2+ lymphadenectomy due to difficulties in predicting station 12a lymph node metastasis.

Abstract
PURPOSE Limited gastrectomy has been generally performed in clinical T1N0 gastric cancer. The aim of this study was to identify risk factors for stage underestimation in clinical T1N0 gastric cancer. METHODS This study reviewed the medical records of 566 patients who underwent gastrectomy for clinical T1N0 gastric cancer. RESULTS The tumor stage was underestimated in 122 (21.6%) patients. The relapse-free survival rate was significantly lower in the patients with pathological stage II (P = 0.021) and III (P < 0.001) disease than in those with pathological stage IA disease. In the multivariate analysis, a location in the upper third of the stomach, tumor size of ≥ 30 mm, undifferentiated adenocarcinoma and clinical tumor depth of SM were identified as independent risk factors for pathological stages II and III. The rate of pathological stages II and III was 0% in the patients with no risk factors, 3% in those with 1 risk factor, 10.5% in those with 2 risk factors, 19.8% in those with 3 risk factors and 50% in those with 4 risk factors. CONCLUSIONS Location, tumor size, undifferentiated adenocarcinoma and clinical tumor depth were independent risk factors for pathological stages II and III in clinical T1N0 gastric cancer.

Prognostic Value of Metastatic Lymph Node Ratio in Pancreatic Cancer. Indian J Surg Oncol 2019; 10:50-54. [PMID: 30948872 DOI: 10.1007/s13193-018-0824-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2018] [Accepted: 10/22/2018] [Indexed: 12/12/2022] Open
Abstract
Lymph node involvement in pancreatic adenocancer is one of the strongest predictors of prognosis. However, the extent of lymph node dissection is still a matter of debate and number of dissected nodes varies widely among patients. In order to homogenize this diverse group of patients and more accurately predict their prognosis, we aimed to analyze the effect of metastatic lymph node ratio as an independent prognostic factor. We retrospectively analyzed medical recordings of 326 patients with pancreatic cancer who were treated in a tertiary medical oncology center over a 10-year period. Both in univariate and multivariate analyses, metastatic lymph node ratio proved to be a strong predictor of prognosis which was unaffected from heterogeneity of our patient population and can be used to facilitate predict prognosis of patients who underwent lymph node dissection to various extents and with future studies it can emerge as a successful tool for creating prognostic subgroups of the disease.

A Simplified Two-Step Technique for Extended Lymphadenectomy During Resection of Gastroesophageal Malignancy: Early Results Compared to En Bloc Dissection. J Gastrointest Surg 2019; 23:393-401.

Abstract
BACKGROUND Extended lymph node dissection (ELND) remains an important component of curative intent resection of mid-stage gastric cancer (GC). Benefits include enhanced staging accuracy, extending regional disease control, and optimizing potential curability. ELND during gastrectomy remains underutilized in US centers due to a low prevalence of GC operations. METHODS The traditional en bloc ELND was modified into a two-step technique to facilitate greater ease of dissection with better exposure. After completion of the gastrectomy component, retrogastric nodes are dissected in a separate, contiguous specimen. Resulting data were compared to outcomes after en bloc resection. RESULTS Of 179 consecutive patients undergoing gastrectomy, 129 underwent an ELND (73%). There were 97 men and 32 women, with a median age of 64 years (range 24-98). The median total LN count was 25 (3-86). The two-step dissection yielded an average of 18.3 (± 8.5 S.D.) perigastric and 12.1 (± 5.8) retrogastric nodes. Two-step LND was associated with lower estimated blood loss (265 vs. 448 ml, p = 0.0005), lower transfusion requirements (6 vs. 28%, p = 0.007), greater mean total LN counts (30 vs. 26, p = 0.03), and a greater rate of obtaining at least 15 or 20 LNs (91 vs. 77% and 83 vs. 65%, p = 0.05). Major morbidity (overall 16%), length of stay, and survival outcomes were not different. CONCLUSIONS The two-step LND technique as described was found to be associated with favorable operative and postoperative outcome parameters and an excellent LN yield. It can be recommended for standard ELND indications in the absence of macroscopically abnormal LNs.

Abstract
Gastric cancer is a common disease with high mortality. The definition of advanced gastric cancer is still debated. Radical surgery associated to appropriate systemic and intra-abdominal chemotherapy is the gold standard treatment. In presence of peritoneal carcinosis, reaching a complete cytoreduction is the key to achieve long-term survival. Adequate lymphadenectomy is also fundamental. Conversion therapy could be applied to selected IV stage patients. No definitive evidences exist regarding the oncological and surgical superiority of mini-invasive approaches over the classical open techniques.

Abstract
Background Surgical resection with lymph node dissection is the primary therapeutic modality for gastric cancer. National Cancer Database (NCDB) was used to determine the extent of lymph nodes (LNs) dissection for gastric cancer. Methods The NCDB was queried from 2004-2013 for patients with margin-negative, invasive resected gastric cancer. The optimal number of LNs dissected was determined using a univariate χ2 cut-point analysis. Multiple sensitivity analyses were utilized to decrease bias. Results A total of 17,851 patients were included. For all patients, the optimal number of LNs needed to be examined was 20+ nodes. When correcting for stage migration (<7 LNs removed), the optimal cut-off value was 20+ LNs. When stratifying by pathologic nodal stage, the cut-off point was 10+ LNs for pN1 and pN2. The 5-year survival was 30.6%±1.6% for 0-9 removed LNs compared to 48.2%±1.2% for 10+ removed LNs (P<0.001) in pN1 disease and 18.3%±1.7% for 0-9 removed LNs compared to 32.6%±1.2% for 10+ removed LNs (P<0.001) in pN2 disease. For pN3 disease, the optimal cut-off point was 20+ LNs; the 5-year survival was 17.2%±1.3% for 0-19 removed LNs compared to 28.5%±1.7% for 20+ removed LNs (P<0.001). Moreover, the outcome was inferior among patients who had >10% positive dissected LNs (P<0.05). Conclusions The extent of dissected lymph nodes of 20 or greater lymph nodes was associated with superior survival. Extended LN dissection is to be considered especially in patients with clinical lymphadenopathy.

Abstract
Background Therapeutic value of lymph node dissection along the superior mesenteric vein (14v) and the posterior surface of the pancreatic head (13) remains unclear in gastric cancer patients. Methods We reviewed 355 patients with advanced gastric cancer in the lower third of the stomach who had undergone gastrectomy at our hospital. Results The frequency of lymph node (LN) metastasis was 10.2% and 7.4% in stations 13 and 14v, respectively. The frequency of station 13 metastasis was 26.8% for T3/T4 tumors with group 2 LNs metastasis and 1.4% for all other tumors. The frequency of station 14v metastasis was 22.2% for T3/T4 tumors with group 2 LNs metastasis and 1.8% for all other tumors. The therapeutic values for dissecting LN stations 13 and 14v were 1.9 and 0.9, respectively, similar to the therapeutic value for group 2 LN dissection. Conclusion Because metastasis to stations 13 and 14v occurs frequently in patients with T3/T4 gastric cancer located in the lower third of the stomach who also have metastasis to group 2 LNs, stations 13 and 14v should be dissected in these patients.

Abstract
Gastric cancer with metastases outside of the regional lymph nodes is deemed oncologically unresectable. Nevertheless, some metastatic lesions are technically resectable by applying established surgical techniques such as para-aortic lymphadenectomy and hepatectomy. At the time of compilation of the Japanese gastric cancer treatment guidelines version 4, systematic reviews were conducted to see whether it is feasible to make any recommendation to dissect both the primary and metastatic lesions with intent to cure, possibly as part of multimodality treatment. Long-term survivors were found among carefully selected groups of patients both in prospective and retrospective studies. In addition, there is a growing list of publications reporting encouraging outcomes of gastrectomy conducted after exceptionally good response to chemotherapy, usually among patients who underwent R0 resection. This type of surgery is often referred to as conversion surgery. It is sometimes difficult to define a clear borderline between curative surgery scheduled after neoadjuvant chemotherapy and the conversion surgery. This review summarizes what we knew after the literature reviews conducted at the time of compiling the Japanese guidelines and in addition reflects some new findings obtained thereafter through clinical trials and retrospective studies. Metastases were divided into three categories based on the major metastatic pathways: lymphatic, hematogenous, and peritoneal. In each of these categories, there were findings that could provide hope for patients with metastatic disease. These findings implied that the surgical technique that we already use could become more useful upon further developments in antineoplastic agents and drug delivery.

Abstract
Background Surgical therapy of mid-stage gastric cancer (GC) and other neoplastic conditions requiring gastric resection remains at the center of curative outcomes, while epidemiologic changes and multimodality treatment options have evolved rapidly. Putative quality metrics for gastrectomy such as R0 rate, total lymph node (LN) count or postoperative morbidity may depend partly on changing disease and treatment patterns, and deserve evaluation under various practice conditions. Methods Data within a U.S.-based single surgical oncologist's practice over 15 years were prospectively recorded and retrospectively analyzed for clinicopathologic factors, operative treatment aspects and outcomes. Trends and spectrum changes over three time intervals were analyzed with contingency analysis and continuous data comparative statistics. Results Of 179 patients undergoing gastric resection, 119 were male and 60 female, with a median age of 63 years (range, 24-98 years). Resections included 56 total, 56 subtotal/distal, 30 proximal and 37 segmental gastrectomies. Diagnoses included 96 GCs, 31 gastroesophageal (GE) junction (GEJ) cancers, 21 GI stromal tumors (GISTs), and 31 other conditions. Significant trends from first towards last time interval were observed for resection type (16% to 32% proximal, 9% to 30% segmental, P=0.0003), curative intent (76% to 98%, P=0.002), diagnosis (5% to 42% GEJ cancer, P<0.0001) and preoperative therapy use (0% to 58%, P<0.0001), among others. Intraoperative aspects showed significantly reduced blood loss (median: 500 to 150 mL) and transfusion requirements (39% to 4%), and an increased use of minimally invasive techniques over time (all at P<0.001). Among patients undergoing curative intent GC resection with LN dissection, total LN counts remained steady (mean: 26), while the number of involved LNs decreased (9.0 to 3.7, P=0.0003) and the R0 resection rate increased from 74% to 85% (P=0.05). The number of specimens with >15 LNs examined increased from 69.0% to 92.5% (P=0.022). At the same time, spleen preservation rate (91% overall) and major morbidity (16%) remained unchanged throughout. Postoperative length of stay decreased from a median of 12 to 8 days (P<0.0001). Conclusions This experience represents some variable practice patterns within a clinicopathologic spectrum of GE diseases. Postoperative or oncologic quality metrics have been sustained or did improve, which would support their utility for various practice settings; they compare favorably to other published U.S. experiences during the same time period.

Abstract
East Asian surgeons generally report lower morbidity and mortality rates for gastrectomy with D2 lymphadenectomy than do surgeons in Western countries; however, the disparity remains unexplained. The aim of this article was to determine the feasibility and safety regarding cases in which East Asian surgeons perform such procedures in Caucasian patients (CPs). Twelve CPs underwent gastrectomy with lymphadenectomy for gastric cancer at Yonsei University Severance Hospital, Seoul, Korea between June 2011 and April 2014. Procedures performed included total gastrectomy (7 of 12, 58%), distal gastrectomy (4 of 12, 33%), and completion total gastrectomy (1 of 12, 8%). Nine patients (75%) underwent D2 lymphadenectomy, and D1+ lymphadenectomy was performed in three others (25%). In four patients (33%), combined resections were carried out. The median values of surgical parameters were as follows: operative time, 266.5 min (range, 120-586 min); estimated blood loss, 90 mL (range, 37-350 mL); retrieved lymph node count, 37.5 (range, 22-63); and postoperative hospital stay, 13.7 days (range, 5-63 days). No mortality was encountered, although two patients (17%) experienced complications (both Clavien-Dindo classification grade IIIa anastomotic leakages), which were successfully managed by conservative treatment. In the hands of East Asian surgeons, mortality and short-term morbidity appears to be acceptably low in CPs subjected to gastrectomy with lymphadenectomy for gastric cancer.

Abstract
Despite a continually decreasing incidence trend, gastric cancer remains a high-risk malignancy. Symptoms are often unspecific, and upper gastrointestinal endoscopy is the key modality for diagnosing early and intermediate-stage disease. Surgeons play a critical role in guiding and managing multiple aspects of gastric cancer diagnosis and care. Potentially curable gastric adenocarcinoma has to be free of distant metastasis and should be staged through endoscopic ultrasound and computed tomography. Early (T1N0) gastric cancer can be considered for endosopic mucosal resection or submucosal dissection. All other M0 stage groups should be evaluated for preoperative chemotherapy or chemoradiation followed by resection through a multidisciplinary approach. Laparoscopic staging, complete (R0) resection, and extended lymphadenectomy (D2 dissection) are critical operative components that optimize curability during gastrectomy. The morbidity potential after gastrectomy remains high; splenectomy and distal pancreatectomy should be avoided if possible to minimize postoperative complications. Laparoscopic gastric cancer resections are increasingly pursued and have not shown disadvantages to open gastrectomy as long as oncologic principles are followed. For the palliation of specific symptoms in patients with incurable gastric cancer, operative interventions should be applied selectively if less invasive modalities are insufficient and only if a meaningful benefit can be expected from a resection or bypass procedure. Prophylactic total gastrectomy should be considered for individuals at risk for hereditary diffuse-type gastric cancer through germline E-cadherin gene mutations. Surgeons engaging in gastric cancer care are expected to provide specialty expertise in order to plan and deliver appropriate care, minimize postoperative morbidity, and optimize resulting survival.

Abstract
As surgeons in India strive to keep pace with the technical advances in the field of laparoscopic surgery, we endeavor to evaluate the mounting global evidence regarding laparoscopic gastric and colorectal resections for cancer. We seem to be riding on the crest of excellence in traditional open surgery for gastrointestinal malignancies, opening avenues for research and for the establishment of practice guidelines in laparoscopic surgery. Results from available trials along with those from ongoing studies are paving the path toward the acceptance and standardization of these procedures. What must be ascertained is whether sound oncological principles, which are ultimately exhibited by long-term outcomes, are being preserved while garnering the established benefits of minimally invasive surgery.

Abstract
Surgery is the oldest oncological discipline, dating back thousands of years. Prior to the advent of anaesthesia and antisepsis 150 years ago, only the brave, desperate, or ill-advised patient underwent surgery because cure rates were low, and morbidity and mortality high. However, since then, cancer surgery has flourished, driven by relentless technical innovation and research. Historically, the mantra of the cancer surgeon was that increasingly radical surgery would enhance cure rates. The past 50 years have seen a paradigm shift, with the realization that multimodal therapy, technological advances, and minimally invasive techniques can reduce the need for, or the detrimental effects of, radical surgery. Preservation of form, function, and quality of life, without compromising survival, is the new mantra. Today's surgeons, no longer the uneducated technicians of history, are highly trained medical professionals and together with oncologists, radiologists, scientists, anaesthetists and nurses, have made cancer surgeries routine, safe, and highly effective. This article will review the major advances that have underpinned this evolution.

Abstract
BACKGROUND Eastern literature is remarkable for presenting survival rates for surgical treatment of gastric adenocarcinoma superior to those presented in western countries. AIM To analyze the long-term result after D2 gastrectomy for gastric cancer. METHODS Two hundred seventy four underwent gastrectomy with D2 lymph node dissection as exclusive treatment. The inclusion criteria were: 1) lymph node removal according to Japanese standardized lymphatic chain dissection; 2) potentially curative surgery described in medical records as D2 or more lymph node dissection; 3) tumoral invasiveness of gastric wall restricted to the organ (T1-T3); 4) absence of distant metastasis (N0-N2/M0); 5) a minimum of five years follow-up. Clinical pathological data included sex, age, tumor location, Borrmann's macroscopic tumor classification, type of gastrectomy, mortality rates, hystological type, TNM classification and staging according to UICC TNM 1997. RESULTS Total gastrectomy was performed in 77 cases (28.1%) and subtotal gastrectomy in 197 (71.9%). The tumor was located in the upper third in 28 cases (10.2%), in the middle third in 53 (19.3%), and in the lower third in 182 (66.5%). Among patients that had their Borrmann's classification assigned, five cases (1.8%) were BI, 34 (12.4%) BII, 230 (84.0%) BIII and 16 (5.9%) BIV. Tumors were histologically classified as Laurén intestinal type in 119 cases (43.4%) and as diffuse type in 155 (56.6%). According to UICC TNM 1997 classification, early gastric cancer (T1) was diagnosed in 68 cases (24.8 %); 51 (18.6%) were T2, and 155 (56.6%) were T3. No lymph node involvement (N0) was observed in 129 cases (47.1%), whereas 100 (36.5%) were N1 (1-6 lymph nodes), and 45 (16.4%) were N2 (7-15 lymph nodes).The median number of lymph nodes dissected was 35. The overall long-term (five-year) survival rate, for stages I to IIIb was 70.4%. CONCLUSION Digestive surgeons must be stimulated in performing D2 gastrectomies to avoid wasting the only treatment to gastric adenocarcinoma that has proven to be efficient up to this days. It must be emphasized that standardized lymph nodes dissection according to tumor location is more important that only the number of removed nodes.

Abstract
BACKGROUND The oncologic safety and feasibility of laparoscopic D2 gastrectomy for advanced gastric cancer are still uncertain. The aim of this study is to compare our results for laparoscopic D2 gastrectomy with those for open D2 gastrectomy. METHODS Between 1998 and 2008, a total of 336 patients with clinical T2, T3, or T4 tumors underwent laparoscopic (n = 186) or open (n = 150) gastrectomy involving D2 lymph node dissection with curative intent. To produce this study population, 123 patients in the open group who matched those of the laparoscopic group with regard to age, sex, body mass index (BMI), American Society of Anesthesiologists (ASA) score, tumor location, and clinical tumor stage were retrospectively selected. The short- and long-term outcomes of these patients were examined. RESULTS Laparoscopic D2 gastrectomy was associated with significantly less operative blood loss and shorter hospital stay, but longer operative time, compared with open D2 gastrectomy. The mortality and morbidity rates of the laparoscopic group were comparable to those of the open group (1.1 % vs. 0, P = 0.519, and 24.2 % vs. 28.5 %, P = 0.402). The 5-year disease-free and overall survival rates were 65.8 and 68.1 % in the laparoscopic group and 62.0 and 63.7 % in the open group (P = 0.737 and P = 0.968). There were no differences in the patterns of recurrence between the two groups. CONCLUSIONS This study suggests that laparoscopic D2 gastrectomy provides reasonable oncologic outcomes with acceptable morbidity and low mortality rates. Although operation time is currently long, this approach is associated with several advantages of laparoscopic surgery, including quick recovery of bowel function and short hospital stay. Laparoscopic D2 gastrectomy may offer a favorable alternative to open D2 gastrectomy for patients with advanced gastric cancer.

Abstract
UNLABELLED The aim of the study was to analyze epidemiologic parameters, treatment-related data and prognostic factors in the management of gastric cancer patients of a university surgical center under conditions of routine clinical care before the onset of the era of multimodal therapies. By analyzing our data in relation with multi-center quality assurance trials [German Gastric Cancer Study - GGCS (1992) and East German Gastric Cancer Study - EGGCS (2004)] we aimed at providing an instrument of internal quality control at our institution as well as a base for comparison with future analyses taking into account the implementation of evolving (multimodal) therapies and their influence on treatment results. MATERIAL AND METHODS Retrospective analysis of prospectively gathered data of gastric cancer patients treated at a single institution during a defined 10-year time period with multivariate analysis of risk factors for early postoperative outcome. RESULTS From 04/01/1993 through 03/31/2003, a total of 328 gastric cancer patients were treated. In comparison with the EGGCS cohort there was a larger proportion of patients with locally advanced and proximally located tumors. 272 patients (82.9%) underwent surgery with curative intent; in 88.4% of these an R0 resection was achieved (EGGCS/GGCS: 82.5%/71.5%). 68.2% of patients underwent preoperative endoluminal ultrasound (EUS) (EGGCS: 27.4%); the proportion of patients undergoing EUS increased over the study period. Diagnostic accuracy of EUS for T stage was 50.6% (EGGCS: 42.6%). 77.2% of operated patients with curative intent underwent gastrectomy (EGGCS/GGCS: 79.8%/71.1%). Anastomotic leaks at the esophagojejunostomy occurred slightly more frequently (8.8%) than in the EGGCS (5.9%) and GGCS (7.2%); however, postoperative morbidity (36.1%) and early postoperative mortality (5.3%) were not increased compared to the multi-center quality assurance study results (EGGCS morbidity, 45%); EGGCS/GGCS mortality, 8%/8.9%). D2 lymphadenectomy was performed in 72.6% of cases (EGGCS: 70.9%). Multivariate analysis revealed splenectomy as an independent risk factor for postoperative morbidity and ASA status 3 or 4 as an independent risk factor for early postoperative mortality. The rate of splenectomies performed during gastric cancer surgery decreased substantially during the study period. CONCLUSIONS Preoperative diagnostics were able to accurately predict resectability in almost 90% of patients which is substantially more than the corresponding results of both the EGGCS and the GGCS. In the future, more wide-spread use of EUS will play an increasing role as stage-dependent differentiation of therapeutic concepts gains acceptance. However, diagnostic accuracy of EUS needs to be improved. Our early postoperative outcome data demonstrate that the quality standard of gastric cancer care established by the EGGCS is being fulfilled at our institution in spite of distinct characteristics placing our patients at higher surgical risk. Besides being a valuable instrument of internal quality control, our study provides a good base for comparison with ongoing analyses on future developments in gastric cancer therapy.

Abstract
PURPOSE Chemoradiation after surgery for locally advanced gastric cancer improves overall and relapse-free survival compared with observation. However, locoregional recurrences remain high. Accordingly, we instituted this pilot/feasibility study, including intraperitoneal 5-fluoro-2'-deoxyuridine (IP FUDR) as part of the treatment. METHODS Gastric/gastroesophageal junction adenocarcinoma stage Ib-IV (M0) patients who underwent R(0) resection were eligible and had IP catheters inserted at time of surgery. IP FUDR (3 g/dose/day) was given during study days 1-3 and 15-17 before combined 5-fluorouracil, leucovorin, and external beam radiation (45 Gy). Endpoints included toxicity, completion rate, locoregional recurrence, and survival. RESULTS Twenty-eight patients (22 men) were enrolled from 2002-2006 at two institutions; their median age was 59.5 years. After R(0) resection, a median 22 (range, 8-102) lymph nodes were examined, and 22 patients had positive nodes. AJCC stages were IB (n = 8), II (n = 10), IIIA (n = 5), IIIB (n = 1), and IV (n = 4). Full-dose IP FUDR and chemoradiation treatment was completed in 20 and 25 patients, respectively. At nearly 4-year median follow-up, 11 patients were disease-free, 5 were alive with disease, 7 were dead of disease, and 1 was dead from other cause; 4 have been lost to follow-up. Recurrences were local in one, intra-abdominal in six, distant in two, multiple sites in two, and unknown in one. The median relapse-free survival is 65.3 months, and the median overall survival has not yet been reached. CONCLUSIONS IP FUDR before chemoradiation after R(0) gastric cancer resection is well tolerated without compromising completion of postoperative adjuvant treatment. Larger randomized trials studying IP FUDR as part of gastric cancer multidisciplinary treatment are needed to prove efficacy in reducing regional recurrence and improving survival.

Abstract
BACKGROUND The prognostic factors and surgical management of gastric cancer invading adjacent organs remains controversial. The aim was to provide valuable prognostic and surgical information on patients with gastric cancer invading adjacent organs. METHODS The retrospectively study included 367 patients who underwent gastric resection for gastric cancer invading adjacent organs. Clinicopathologic variables were evaluated as predictors of long-term survival by univariate and multivariate analyses. Multivariate analysis was performed using Cox's proportional hazards model. RESULTS The five-year survival rate was 10.1%, and median survival period was 14 months. The five-year survival rate was influenced by histologic type, lymph node metastasis, liver metastasis, peritoneal dissemination, extent of lymph node dissection and curability of operation. Of these, independent prognostic factors were lymph node metastasis (N2, N3 versus N0, N1, relative risk 2.028, P < 0.001), liver metastasis (present versus absent, relative risk 1.582, P= 0.023) and curative resection (no versus yes, relative risk 1.719, P < 0.001). A significant survival benefit for curative resection was observed with a five-year survival rate of 21.5% compared with non-curatively resected cases (5.1%). CONCLUSIONS In patients with gastric cancer invading adjacent organs, three independent prognostic factors were lymph node metastasis, liver metastasis, and curative resection. For patients with gastric cancer invading adjacent organs, we recommend performing combined organ resection in patients with locally advanced gastric carcinoma regardless of curability.

Abstract
BACKGROUND Westernization of lifestyle and diet has resulted in an increase in overweight patients in Japan. Although the adverse effects of higher body mass index (BMI) on early surgical outcomes are known, the relationship between BMI and long-term outcome is unclear. MATERIALS AND METHODS Clinicopathological characteristics and 5-year survival rate of overweight (BMI >or= 25 kg/m2; H-BMI; n = 1126) and nonoverweight (BMI < 25 kg/m2; N-BMI; n = 6799) patients who underwent gastrectomy with curative intent at the Cancer Institute Hospital between 1970 and 2004 were compared. RESULTS Patients in the H-BMI group tended to have earlier-stage disease. The 5-year survival rate was significantly better in the H-BMI than N-BMI group (81.5% vs 74.1%, respectively; P < .001). Postoperative mortality was 1% in both groups (P = .482), whereas postoperative morbidity was 22% and 19% in the H-BMI and N-BMI groups, respectively (P = .007). Multivariate analysis indicated overweight, age, gender, surgical procedure, histology, operation year, pT, and pN as independent prognostic factors. Subset analyses of pT and pN stages revealed overweight as an independent prognostic factor in patients with pT1 and pN0. CONCLUSION The 5-year survival rate following curative gastrectomy is better in overweight than nonoverweight Japanese patients, especially for early-stage gastric cancer. Further studies are needed to determine whether these results apply to other countries where morbidity and mortality for gastric cancer are higher than in Asian countries.

Abstract
BACKGROUND Laparoscopy-assisted distal gastrectomy (LADG) with standard D2 dissection is a complex procedure usually performed only by experienced surgeons, and the feasibility of this procedure still remains unclear. METHOD Patients who underwent LADG at the Cancer Institute Hospital between April 2006 and October 2008 were recruited for this study. Early surgical outcomes were compared between patients who underwent complete D2 dissection (complete D2 group; n = 42) and those who underwent D1 + beta dissection (D1 + beta group; n = 179) to determine the feasibility of laparoscopic D2 lymph node dissection. RESULTS In complete D2 group, the operation time was longer (253 +/- 10 vs 224 +/- 4 min; P = 0.005), and the number of retrieved lymph nodes was larger (41 +/- 2 vs 35 +/- 1; P = 0.002) compared with those in D1 + beta group. The other early surgical outcomes monitored for the two groups were not different between groups. CONCLUSIONS LADG with complete D2 lymph node dissection can be performed safely if the procedure is standardized and an experienced laparoscopic surgeon performs the surgery. To be accepted as a standard treatment for advanced gastric cancer, well-designed prospective trial is necessary.

Abstract
BACKGROUND Obesity is generally considered a risk factor for postoperative morbidity following open gastrectomy. Body mass index (BMI) is widely accepted as an indicator of obesity, but does not necessarily reflect the distribution of fat. It is unclear how different types of fat may affect the operative procedure and outcome. METHODS The relationship between fat area (total, visceral and subcutaneous fat, and BMI) and early surgical outcomes (bleeding, operating time, morbidity, hospital death and hospital stay) was investigated in 135 patients who had a curative gastrectomy at the Cancer Institute Hospital, Tokyo, in 2006. RESULTS Postoperative intra-abdominal infection, which occurred in 13 patients (9.6 per cent), correlated strongly with visceral (P = 0.023) and total (P = 0.037) fat area. Visceral fat area also correlated with hospital death (P = 0.041) and a longer hospital stay (P = 0.001). Subcutaneous fat area and BMI did not correlate with these early surgical outcomes. CONCLUSION Patients with a high visceral fat area are more likely to develop an intra-abdominal infection after gastrectomy. Assessment of fat area, in particular visceral fat area, should alert surgeons to increased postoperative risks.

Abstract
BACKGROUND Gastrectomy with D2 lymph node dissection is the standard treatment for locally advanced gastric cancer in Japan. However, in patients with a preoperative diagnosis of early gastric cancer, gastrectomy with limited lymph node dissection is generally selected as a treatment option, despite a pathological diagnosis of advanced gastric cancer. The aim of the present study was to clarify the clinicopathological characteristics and feasibility of limited lymph node dissection in patients with clinically early, but pathologically advanced, gastric cancer. MATERIALS AND METHODS Clinicopathological characteristics, including the incidence and susceptible sites for lymph node metastasis, were investigated in 1528 patients with a final diagnosis of T2 gastric cancer treated at the Cancer Institute Hospital. For these patients, the results were compared between two groups including 266 patients preoperatively diagnosed as early T1 gastric cancer (EpT2) and 1262 patients preoperative diagnosed as locally advanced gastric cancer (ApT2). RESULTS The pathological stage was lower (P < .001), and the 5-year survival rate was better (91.0% vs. 73.1%, P < .001) for the EpT2 group compared with the ApT2 group. Moreover, the N stage was smaller in the EpT2 group than in the ApT2 group, and the extension of lymph node metastasis was limited in 261 out of 266 patients (98%). CONCLUSION Patients with EpT2 gastric cancer had a better 5-year survival rate than the patients in the ApT2 group. Gastrectomy with limited lymph node dissection could be indicated for patients with EpT2 gastric cancer unless intraoperative finding indicated obvious lymph node metastasis.

Therapeutic value of lymph node dissection in advanced gastric cancer with macroscopic duodenum invasion: is the posterior pancreatic head lymph node dissection beneficial? Ann Surg Oncol 2009; 16:1241-6. [PMID: 19224285 DOI: 10.1245/s10434-009-0345-4] [Citation(s) in RCA: 37] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2008] [Revised: 01/09/2009] [Accepted: 01/09/2009] [Indexed: 12/18/2022]
Abstract
BACKGROUND In advanced gastric cancer (AGC) with duodenum invasion, the posterior pancreatic lymph nodes are susceptible to metastasis because of their proximity to the duodenum. The therapeutic value of lymph node dissection in this area for AGC with macroscopic duodenum invasion remains unclear. METHODS Patients who had undergone curative gastrectomy for lower-third AGC from 1970 to 2004 at the Cancer Institute Hospital were recruited for this study. Clinicopathological data were collected retrospectively, and compared between cases of AGC with duodenum invasion (AGC-DI group) and AGC without duodenum invasion (AGC-nDI group). In the AGC-DI group, the therapeutic value of lymph node dissection was evaluated using a therapeutic index (multiplication of the frequency of metastasis to the station by the 5-year survival rate of patients with metastasis to that station). RESULTS The AGC-DI group generally had tumors of higher pathological stage, which might account for the poorer 5-year survival rate compared with that of the AGC-nDI group (50.1% versus 68.5%; P = 0.0002). The incidence of lymph node metastasis was higher in the AGC-DI group than that in the AGC-nDI group, including nodes in the posterior pancreatic head (23.9% versus 7.0%, P < 0.0001). In the AGC-DI group, posterior pancreatic head lymph node dissection was of therapeutic value (4.19) equivalent to dissection of second-tier lymph nodes. CONCLUSIONS The dissection of posterior pancreatic head lymph nodes might be effective in AGC with macroscopic duodenum invasion since this has therapeutic value equivalent to that of second-tier lymph node dissection and might improve patients' long-term outcomes.

Abstract
AIM The study by MacDonald et al. [Chemoradiotherapy after surgery compared with surgery alone for adenocarcinoma of the stomach or gastroesophageal junction. N Engl J Med 2001;345:725-30] has reported low loco-regional recurrence rates (19%) after gastric cancer resection and adjuvant radiotherapy. However, the lymph node dissection was often "inadequate". The aim of this retrospective study is to analyse if an extended lymph node dissection (D2) without adjuvant radiotherapy may achieve comparable loco-regional recurrence rates. METHODS A prospective database of 200 patients who underwent a curative resection for gastric carcinoma from January 2000 to December 2006 was analysed. D2 lymph node dissection was standard. Recurrences were categorized as loco-regional, peritoneal, or distant. No patients received neoadjuvant or adjuvant radiotherapy. RESULTS The in-hospital mortality rate was 1% (2 patients). The mean number of dissected lymph nodes was 25.9. Overall and disease-free survival at 5years were 60.7% and 61.2% respectively. During the follow-up, 60 patients (30%) have recurred at 76 sites: 38 (50%) distant metastases, 25 (32.9%) peritoneal metastases, and 13 (17.1%) loco-regional recurrences. The loco-regional recurrence was isolated in 6 patients and associated with peritoneal or distant metastases in 7 patients. The mean time to the first recurrence was 18.9 (95% confidence interval: 15.0-21.9) months. CONCLUSIONS Extended lymph node dissection is safe and warrants low loco-regional recurrence rates.

Abstract
AIMS We conducted a retrospective case-control study to compare the prognostic differences of lymph node-positive gastric cancer patients between dissected lymph nodes (DLNs) <15 group and DLNs > or =15 group. METHODS A retrospective study of 323 lymph node-positive gastric patients who underwent potentially curative resection for gastric cancer was analyzed to identify the prognostic differences between DLNs <15 group and DLNs > or =15 group. Of these patients, 49 patients with <15 DLNs were matched with 147 patients with > or =15 DLNs according to gender, age, location of primary tumor, and type of gastrectomy. RESULTS Patients with n1 lymph node metastasis (according to JCGC), serosal involvement, ratio of positive lymph nodes less than 25%, or without adjuvant chemotherapy in > or =15 DLN group had comparatively longer median survival than patients with homologous clinicopathologic variables in <15 DLN group, respectively. Patients with n1 stage lymph node metastasis, serosal involvement, non-intestinal Lauren classification, or without adjuvant chemotherapy in <15 DLN group had higher recurrence rate than patients with homologous clinicopathologic variables in > or =15 DLN group, respectively. In addition, we demonstrated that patients with more than n1 stage lymph node metastasis in <15 DLN group had higher rate of peritoneal dissemination than those with more than n1 lymph node metastasis in > or =15 DLN group. CONCLUSIONS DNL > or =15 was an important factor to improve the prognosis of lymph node-positive gastric cancer patients after potential curative resection.

Abstract
OBJETIVO: Descrever e analisar as principais complicações pós-operatórias e mortalidade dos pacientes submetidos à ressecção gástrica por câncer gástrico com linfadenectomia D2. MÉTODO: Foi realizada uma coorte histórica onde as principais variáveis em estudo foram: idade, localização do tumor, estadiamento, complicações do procedimento cirúrgico, padrão de recidiva tumoral, análise da sobrevida livre de doença e sobrevida total. RESULTADOS: Foram avaliados 35 pacientes submetidos à dissecção linfonodal D2 no período de Janeiro de 2000 a Dezembro de 2004. A média de idade foi 57 anos. Apenas um (2,9%) paciente apresentava tumor precoce e o local mais comum do tumor foi no terço médio do estômago. O número de linfonodos ressecados por paciente variou de 15 a 80 linfonodos (média 28,8). Vinte e seis (74,3%) pacientes apresentaram linfonodos metastáticos, sendo a média de 13,4 (±11,8) linfonodos comprometidos por paciente. Seis (17,1%) pacientes apresentaram complicações no período pós-operatório, sendo duas pneumonias, uma fístula pancreática, uma fístula do coto duodenal e duas deiscências da anastomose esôfago-jejunal. Apenas um (2,86%) paciente morreu devido a complicações operatórias. O tempo de seguimento médio foi de 26 meses. Vinte e dois pacientes apresentavam-se vivos no fechamento do estudo, com uma sobrevida atuarial de 62,9%. CONCLUSÃO: Os resultados deste estudo sugerem que, em centros especializados, a linfadenectomia D2 é um procedimento com nível de complicações aceitável e pode ser realizada sem aumento da mortalidade operatória.

Abstract
BACKGROUND AND AIM Laparoscopy-assisted distal gastrectomy (LADG) has not yet been widely adopted for the treatment of gastric cancers because of the perceived complexity of the procedure. In addition to the proficiency of the operator, other factors could potentially be optimized to improve postoperative outcomes. The aim of this study was to evaluate a standardized operative procedure for assistants performing LADG. MATERIALS AND METHODS Of 114 patients, 64 initially underwent conventional LADG (CLDG) and then 50 underwent standardized procedure (SLDG) in which the role of assistant in LADG was completely established. Parameters compared for the SLDG and CLDG groups were operation time, estimated blood loss, intra- or postoperative complications, preservation of the vagus nerve, and the number of pathologically examined lymph nodes. RESULTS The operation time for the SLDG procedure (mean +/- SE, 229 +/- 6 min) was shorter than for the CLDG procedure (261 +/- 8 min; P < 0.002), and the estimated blood loss for SLDG (57 +/- 7 ml) was less than for CLDG (108 +/- 17 ml, P < 0.004). The celiac branch of the vagus nerve was preserved in 73% of SLDG patients compared with 52% of CLDG patients (P < 0.03). More lymph nodes were pathologically examined in SLDG patients (38.3 +/- 1.5) than in CLDG patients (32.5 +/- 1.8, P = 0.02). CONCLUSIONS Standardization of the LADG procedure for assistants enabled a shorter operation time, reduced blood loss, a higher rate of vagus nerve preservation, and more accurate lymph node dissection.

Abstract
BACKGROUND Laparoscopy-assisted approaches have become popular for dissecting early-stage gastric cancer in Japan, but the outcomes after 5 years of followup have not been reported. STUDY DESIGN Between January 1998 and March 2002, 94 patients with histologically proved early-stage gastric carcinoma participated in clinical studies and underwent gastrectomy with regional lymphadenectomy to evaluate feasibility and safety of the laparoscopy-assisted approach. Outcomes and pattern of disease failure during followup up to 5 years were evaluated in all patients. Multivariable analysis was performed to identify relevant prognostic factors. RESULTS Conversion to open procedures occurred in three patients. Median blood loss was 90 mL (interquartile range, 160 mL), and duration of operation was 230 minutes (interquartile range, 60 minutes). Operative morbidity and mortality were 22.3% and 0%, respectively. Nine patients died during the course of followup, for an overall 5-year survival rate of 90%. Two patients died of recurrent disease, and 2 other patients have been diagnosed with recurrences, for a 5-year recurrence-free survival of 95.6%. Three patients with recurrent cancer, including 1 with port-site recurrence, had stage IA disease (pT1pN0) at operation. Diabetes mellitus as a comorbidity was prominent as a prognostic factor. CONCLUSIONS Outcomes of patients with a preoperative diagnosis of early-stage cancer were excellent when treated with a laparoscopy-assisted approach, although rare patterns of disease failure were observed.

Abstract
AIMS No consensus exists on the level and number of lymph nodes to be dissected and examined for accurate staging of patients with resectable gastric cancer. The aim of this study was to examine the prognostic value and staging accuracy of the metastatic lymph nodes ratio (NR). METHODS The postoperative survival of 247 patients with gastric cancer who underwent gastrectomy was analyzed. Lymph nodes status was assigned according to three different classifications: 6th UICC/AJCC TNM; JGCA; NR (NR0: 0%; NR1: < or =20%; NR2: >20%). Staging accuracy of the three classifications was compared according to patients survival. RESULTS A significant difference in survival was observed in patients with NR1 versus NR2. At multivariate analysis only NR along with pT and grading were found to be independent prognostic factors. Stage migration was present in 84 cases (51%) with JGCA classification, in 30 (19%) with 6th UICC/AJCC TNM classification and in only 18 cases (11%) when NR was applied. CONCLUSIONS Our data showed that NR is a simply reproducible and highly reliable staging system with a strong ability to predict patients' outcome. Compared to other nodal staging classifications, NR is less influenced from the number of the lymph nodes dissected and examined, reducing the stage migration phenomenon.

Abstract
BACKGROUND A multicenter, randomized, clinical trial was initiated to evaluate the possible benefits of extended D2 (D2+) lymphadenectomy after potentially curative resection of gastric cancer. METHODS Standard D2 lymphadenectomy was defined according to the Japanese Gastric Cancer Association classification. D2+ lymph node dissection additionally included the removal of para-aortic nodes. RESULTS Of 781 patients screened, 275 were randomized to standard D2 (n = 141) or extended D2+ (n = 134) lymphadenectomy. The overall morbidity rates were comparable in D2 (27.7%; 95% confidence interval [CI], 20.3-35.1) and D2+ (21.6%; 95% CI, 13.7-29.5) groups (P = .248). Pre-existing cardiac disease, splenectomy, and excessive blood loss were identified as risk factors for overall and nonsurgical complications. Postoperative mortality rates were 4.9% (95% CI, 1.4-8.5) and 2.2% (95% CI, 0-4.7), respectively (P = .376). CONCLUSIONS The interim safety analysis failed to show any significant difference with regard to the extent of lymph node dissection. The surgical outcome was not different between the 2 surgeries.

Abstract
BACKGROUND Standard treatment for highly advanced gastric cancer (AGC) has not been established yet. Neoadjuvant chemotherapy (NAC) represents a promising approach, which may improve the prognosis of AGC. In this study, we analyzed the feasibility and efficacy of NAC with S-1 (TS-1)/cisplatin CDDP in order to design appropriate clinical trials for AGC. METHODS Results for a series of 45 consecutive patients with AGC treated with S-1/CDDP induction chemotherapy since January 2002 were analyzed retrospectively. RESULTS The primary tumor was resected in 36 of the 45 patients (resectability, 80.0%). Progression of the disease during chemotherapy was observed in 1 patient only (2.2%). No treatment-related deaths occurred, and serious adverse effects (grade 3-4) were noted in only 2.2% of the patients. The overall median survival time was 1.82 years. Especially noteworthy is that, in patients with highly advanced disease (pretreatment [c]-stage IV; n = 27), resectability was 66.7% and curative (R0) resection was possible in 10 patients. The median survival times for c-stage IV patients who had total, curative, and noncurative resections were 20.8, 22.3 and 12.6 months, respectively. R0 resection was possible for all c-stage III patients (n = 17), with a 2-year overall survival of 90.9%. The downstaging rate was 55.6% (20/36), resulting in a significantly improved prognosis for the downstaged patients (P = 0.012). CONCLUSION Induction chemotherapy using S-1/CDDP for AGC appears to be a safe and promising treatment. We have therefore started two independent multiinstitutional clinical trials to evaluate the efficacy of this treatment.

Abstract
BACKGROUND Advanced, but potentially still curable gastric cancer (stages IIIA, IIIB, or stage IV M0) is associated with very high recurrence rates after gastrectomy. The value of an extended lymph node dissection (ELND) remains unclear in this setting. METHODS A resected gastric cancer data set was created through structured queries to the SEER 1973-2000 database. Relationships between the number of lymph nodes (LNs) examined and survival outcomes were analyzed for the stage subgroups characterized by the N categories N2 or N3, and transmural tumor extension (T categories T2b or T3). RESULTS The study group encompassed 1,377 patients, including T2b/3N2 (n = 1,076) and T2b/3N3 stage subgroups (n = 301). Total LN count (or number of negative LNs examined; P < 0.0001), number of positive LNs (P < 0.0001), age (P < 0.0001), primary site (P = 0.0002), T category (P = 0.0271), race (P = 0.0301) and gender (P = 0.0261) were independent prognostic survival predictors. A cut point analysis yielded the ability to detect significant survival differences for LN numbers up to 30 (N2) or up to 40 (N3), always in favor of the higher number of LNs examined. Best long-term survival outcomes were observed with negative LN counts of more than 15 (N2) or more than 20 (N3). CONCLUSIONS Even in transmural or serosa-positive gastric cancer with advanced nodal involvement, more extensive LN dissection and analysis influences survival. Stage-based survival prediction depends on total LN number and number of negative LNs. The mechanism remains uncertain, but is not limited to stage migration. ELND during potentially curative gastrectomy is recommended even for advanced gastric cancer.

Abstract
BACKGROUND Operative therapy of pancreatic cancer is associated with poor survival because of high recurrence rates after pancreatectomy. The effect of lymph node (LN) dissection on survival continues to be debated. METHODS A pancreatic cancer data set was created through structured queries to the Surveillance, Epidemiology, and End Results 1973 to 2000 database. Stage information was created according to 6th edition American Joint Committee on Cancer tumor-node-metastasis criteria, and the effect of LN number on survival was analyzed. RESULTS Out of a cohort of 20,631 patients with carcinomas of the exocrine pancreas, surgical details were available for 2,787 patients. Procedures included pancreatoduodenectomies (n = 1848; 66%), radical regional pancreatectomies (n = 516; 19%), other partial resections (n = 316; 11%), and total pancreatectomies (n = 107; 4%). For 1666 of these patients with complete clinicopathologic information, the median age was 66 years (range, 22-96 years), with an equal sex ratio. The median number of total LNs examined was 7 (range, 1-52), of positive LNs was 1 (range, 0-34), and of negative LNs was 6 (range, 0-30). Multivariate survival analysis yielded these prognostic variables: number of LNs examined, number of positive LNs, tumor size, extrapancreatic extension, radiotherapy (all P < .0001), and age (P = .0009). The greatest survival differences were observed for negative LN counts of 10 to 15. CONCLUSIONS Stage-based survival prediction of pancreatic cancer is strongly influenced by total LN counts and numbers of negative LNs obtained. Although the mechanism remains unclear and could reflect confounding factors (margin status and institutional volume), an attempt to resect and examine at least 15 LNs to yield preferably between 10 and 15 negative LNs seems sensible for curative-intent pancreatectomy.

Abstract
INTRODUCTION The present study presents the initial results of the use of video-assisted surgery in the curative intent treatment of gastric cancer in a specialised unit of esophago-gastric pathology. METHODS Since December 2002 we have substituted laparotomy for video-assisted surgery for the surgical treatment of gastric cancer. We report our initial experience in 28 patients. In 20 we performed a total gastrectomy with Roux Y esophago-jejunum reconstruction. In another 8 cases we performed subtotal gastrectomy with Roux Y reconstruction. The anastomoses in total gastrectomy were performed with laparoscopy with the EEA head descending via the endo-esophageal route. The resected piece is extracted via minimum laparotomy. The associated complete lympadenectomy D2 was performed in the tumours of the gastric antrum and D1 plus the lymph node groups 7, 8, 9 and proximal 11 at the second level in the gastric body and fundus. RESULTS The mean duration of intervention was 222 minutes and the mean blood loss was 185 ml. Mortality was 3.7% and morbidity was 19%. There was a reduction in post-operative analgesia requirements and the mean hospital stay was 11 days. CONCLUSIONS Gastric resection and related lympadenectomy can be performed using video-assisted surgery in a manner that is as safe as conventional surgery and, further, has considerable advantages. The greater complexity requires that the surgical team is better trained in the use of the laparoscopy technique. In the few studies on the theme, there appears to be no oncological inconveniences associated with the technique.

Abstract
Early detection and accurate preoperative staging of gastric cancer are clinically important because the prognosis and choice of an optimal therapeutic approach are directly related to the stage of a neoplasm at time of presentation. Multidetector row computed tomography is a potentially powerful tool for noninvasive gastric evaluation. When thin collimation is used, near-isotropic imaging of the stomach is possible. Proper air distention of the stomach is used with virtual gastroscopic images; the technique is able to evaluate endoluminal lesions of the stomach and assist in early detection of gastric cancer. Adequate water-filled dynamic multiplanar reformatted images allow the radiologist to choose the optimal imaging plane to accurately evaluate depth of tumor invasion of the gastric wall and perigastric fat plane infiltration, identify a thin fat plane between a tumor and adjacent organs, avoid partial volume averaging effects, and better differentiate lymph nodes from small perigaskric vessels. Thus, the combination of air distention and hydrodistention of the stomach and dynamic contrast-enhanced multidetector row computed tomography with near-isotropic imaging offer improved diagnosis and staging of gastric cancers.

Abstract
BACKGROUND Prognosis of potentially curable (M0), completely resected gastric cancer is primarily determined by pathologic T and N staging criteria. The optimal regional dissection extent during gastrectomy for gastric adenocarcinoma continues to be debated. METHODS A gastric cancer data set was created through structured queries to the Surveillance, Epidemiology, and End Results database (1973 to 1999). Relationships between the number of lymph nodes (LNs) examined and survival were analyzed for the stage subgroups T1/2N0, T1/2N1, T3N0, and T3N1. RESULTS In every stage subgroup, overall survival was highly dependent on the number of LNs examined. Multivariate prognostic variables in the T1/2N0M0 subgroup were number of LNs examined, age (for both, P < .0001), race (P = .0004), sex (P = .0006), and tumor size (P = .02). A linear trend for superior survival based on more LNs examined could be confirmed for all four stage subgroups. Baseline model-predicted 5-year survival with only one LN examined was 56% (T1/2N0), 35% (T1/2N1), 29% (T3N0), or 13% (T3N1). For every 10 extra LNs dissected, survival improved by 7.6% (T1/2N0), 5.7% (T1/2N1), 11% (T3N0), or 7% (T3N1). A cut-point analysis yielded the greatest survival difference at 10 LNs examined but continued to detect significantly superior survival differences for cut points at up to 40 LNs, always in favor of more LNs examined. CONCLUSION Although the impact of stage migration versus improved regional disease control cannot be separated on basis of the available information, the data provide support in favor of extended lymphadenectomy during potentially curative gastrectomy for gastric cancer.

Abstract
Gastric cancer is one of the most common cancers and one of the most frequent causes of cancer-related deaths. The incidence, diagnostic studies, and therapeutic options have undergone important changes in the last decades, but the prognosis for gastric cancer patients remains poor, especially in more advanced stages. Surgery is the mainstay of treatment of this disease, even if it is associated with a high rate of locoregional and distant recurrence. There is ongoing debate regarding the role of adjuvant treatment In advanced disease, palliation of symptoms, rather than cure, is the primary goal of patient management. Several combination therapies have been developed and have been examined in phase III trials; however, in most cases, they have failed to demonstrate a survival advantage over the reference arm. This review summarizes the most important recommendations for the management of patients with gastric cancer.

Abstract
BACKGROUND Extended lymphadenectomy for gastric carcinoma has been associated with high mortality and morbidity rates in several multicentre randomized trials. METHODS Using data from 523 patients registered for a prospective randomized trial comparing extended (D2) and superextended (D3) lymphadenectomies, risk factors for overall complications and major surgical complications (anastomotic leakage, intra-abdominal abscess and pancreatic fistula) were identified by multivariate logistic regression analysis. RESULTS Mortality and morbidity rates were 0.8 per cent (four of 523) and 24.5 per cent (128 of 523) respectively. Pancreatectomy (relative risk 5.62 (95 per cent confidence interval (c.i.) 1.94 to 16.27)) and prolonged operating time (relative risk 2.65 (95 per cent confidence interval 1.34 to 5.23)) were the most important risk factors for overall complications. A body mass index of 25 kg/m2 or above, pancreatectomy and age greater than 65 years were significant predictors of major surgical complications. CONCLUSION Pancreatectomy should be reserved for patients with stage T4 disease. Age and obesity should be considered when planning surgery.

Abstract
BACKGROUND Laparoscopy-assisted surgery with extraperigastric lymph node dissection for gastric cancers has been described, but the clinical benefits of these surgeries still are unclear. Short-term clinical outcomes were compared between laparoscopy-assisted distal gastrectomy (LADG) and conventional open distal gastrectomy (ODG) for early gastric cancer in a prospective randomized fashion. METHODS For this study, 28 patients with early gastric cancers in the lower half of the stomach were randomly assigned to either LADG (n = 4) or ODG (n = 14). Postoperative pain, levels of acute inflammatory responses, and pathologic evaluation of the operative specimens were compared. RESULTS The LADG group required a significantly shorter period of postoperative epidural anesthesia, showed significantly lower levels of serum interleukin-6 and C-reactive protein, and had no major postsurgery complications. Pathologic examinations showed that surgery was equally radical in the two groups. CONCLUSION The findings show that LADG with extraperigastric lymph node dissection is a safe and less invasive alternative to the open procedure.
