Dejeu V, Dejeu P, Muresan A, Bradea P, Dejeu D. Analysis of Patient Outcomes following Curative R0 Multiorgan Resections for Locally Advanced Gastric Cancer: A Systematic Review and Meta-Analysis. J Clin Med 2024; 13:3010. [PMID: 38792552 PMCID: PMC11121797 DOI: 10.3390/jcm13103010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2024] [Revised: 04/30/2024] [Accepted: 05/05/2024] [Indexed: 05/26/2024] Open
Abstract
Background: This systematic review examines the efficacy of multiorgan resection (MOR) in treating locally advanced gastric cancer (LAGC), focusing on survival outcomes, postoperative morbidity, and mortality. Methods: We conducted a comprehensive search of studies in PubMed, Scopus, and Embase up to November 2023, based on the PRISMA guidelines. The inclusion criteria focused on clinical trials, observational studies, case-control studies, and qualitative research, involving patients of any age and gender diagnosed with LAGC undergoing MOR aimed at R0 resection, with secondary outcomes focusing on survival rates, postoperative outcomes, and the effects of adjuvant and neoadjuvant therapies. Exclusion criteria ruled out non-human studies, research not specifically focused on LAGC patients undergoing MOR, and studies lacking clear, quantifiable outcomes. The quality assessment was performed using the Newcastle-Ottawa Scale. The final analysis included twenty studies, involving a total of 2489 patients across a time span from 2001 to 2023. Results highlighted a significant variation in median survival times ranging from 10 to 27 months and R0 resection rates from 32.1% to 94.3%. Survival rates one-year post-R0 resection varied between 46.7% and 84.8%, with an adjusted weighted mean of 66.95%. Key predictors of reduced survival included esophageal invasion and peritoneal dissemination, the presence of more than six lymph nodes, and tumor sizes over 10 cm. Nevertheless, the meta-analysis revealed a significant heterogeneity (I2 = 87%), indicating substantial variability across studies, that might be caused by differences in surgical techniques, patient demographics, and treatment settings which influence survival outcomes. Results: The review underlines the important role of achieving R0 resection status in improving survival outcomes, despite the high risks associated with MOR. Variability across studies suggests that local practice patterns and patient demographics significantly influence results. Conclusions: The findings emphasize the need for aggressive surgical strategies to improve survival in LAGC treatment, highlighting the importance of achieving curative resection despite inherent challenges.

Prognostic factors in T4b gastric cancer after surgery: A more balanced and sequential therapy for patients? J Cancer Res Ther 2024; 20:211-215. [PMID: 38554323 DOI: 10.4103/jcrt.jcrt_811_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2022] [Accepted: 09/16/2022] [Indexed: 04/01/2024]
Abstract
INTRODUCTION This study aimed to evaluate the prognostic factors in T4b gastric cancer (GC) in order to improve future therapeutic strategies. METHODS We retrospectively analyzed the medical records of 43 patients with advanced GC who underwent surgery and were surgically or pathologically diagnosed with T4b GC. The overall survival (OS) rate of patients with T4b GC was analyzed, and univariate and multivariate analyses were performed to identify clinicopathological factors that were independently associated with OS. In addition, we assessed the relationship between postoperative chemotherapy and laboratory parameters 4 weeks post-surgery. RESULTS The proportion of patients with invasion of cancer in organs, including the pancreas, transverse colon, and liver, were 58.1%, 18.6%, and 14.0%, respectively. The proportion of patients who exhibited distant metastases was 44.2%, and R0 resection was achieved in 30.2% of patients. A total of 69.8% of patients underwent postoperative chemotherapy. The median survival rate was 12.3 months. Upon multivariate analysis, the presence of distant metastases (P = 0.01, HR; 3.48), the use of postoperative chemotherapy (P = 0.0004, HR; 0.12), and R0 resection (P < 0.0001, HR; 0.14) were significantly correlated with OS. Patients who did not undergo postoperative chemotherapy showed significantly higher levels of inflammatory parameters and lower levels of nutritional parameters 4 weeks after surgery than those who did. CONCLUSIONS We evaluated that the presence of distant metastases was significantly associated with a poor prognosis, and the use of postoperative chemotherapy and R0 resection was significantly associated with a better prognosis in patients with T4b GC. It would be more important for a T4b GC treatment to balance between therapeutic tolerance for postoperative chemotherapy and surgical therapeutic effect.

Abstract
BACKGROUND Locally advanced gastric cancer (GC) extending to the surrounding tissues may require a multivisceral resection (MVR) to provide the best chance of cure. However, little is known about how the extent of organ resection affects the risks and benefits of surgery. METHODS An electronic database of patients treated between 1996 and 2020 in an academic surgical centre was reviewed. MVRs were defined as partial or total gastrectomy combined with splenectomy, distal pancreatectomy, or partial colectomy. RESULTS Suspected intraoperative tumour invasion of perigastric organs (cT4b) was found in 298 of 1476 patients with non-metastatic GC, and 218 were subject to MVRs, including the spleen (n = 126), pancreas (n = 51), and colon (n = 41). MVRs were associated with higher proportions of surgical and general complications, but not mortality. A nomogram was developed to predict the risk of major postoperative morbidity (Clavien-Dindo's grade ≥ 3a), and the highest odds ratio for major morbidity identified by logistic regression modelling was found for distal pancreatectomy (2.53, 95% CI 1.23-5.19, P = 0.012) and colectomy (2.29, 95% CI 1.04-5.09, P = 0.035). Margin-positive resections were identified by the Cox proportional hazards model as the most important risk factor for patients' survival (hazard ratio 1.47, 95% CI 1.10-1.97). The extent of organ resection did not affect prognosis, but a MVR was the only factor reducing the risk of margin positivity (OR 0.44, 95% CI 0.21-0.87). CONCLUSIONS The risk of multivisceral resections is associated with the organ being removed, but only MVRs increase the odds of complete tumour clearance for locally advanced gastric cancer.

Abstract
Introduction Multivisceral resections (MVRs) in gastric cancer are potentially curable in selected patients in whom clear resection margins are possible. However, there are still uncertain data on their feasibility and safety considering short- and long-term results. The study compares survival, morbidity, mortality, and other secondary outcomes between standard and MVRs for gastric cancer. Materials and Methods A monocentric retrospective study in patients with gastric adenocarcinoma, covering 2004 to 2020. Of the 336 operable cases, 101 patients underwent MVRs. The remaining 235 underwent standard gastric resections (SGRs), of which 173 patients were in stage T3/T4. To compare survival, a control group of 101 patients with palliative procedures was used-bypass anastomosis or exploration. Results MVR had a lower survival rate than the SGR but significantly higher than the palliative procedures. The predominant gender in MVR was male (72.3%), with a mean age of 61 years. The perioperative mortality was 3.96% ( n = 4), and the overall median survival was 28.1 months. The most frequently resected organs were the spleen (67.3%), followed by the pancreas (32.7%) and the liver (20.8%). In 56.4% of the cases two organs were resected, in 28.7% three organs, and in 13.9% four organs. The main complication was bleeding (9.9%). The major postoperative complications in the MVR were 14.85%, and in the SGR 6.4% ( p < 0.05). Better long-term results were observed in patients who underwent R0 resections compared with R1. Conclusion Multiorgan resections are characterized by poorer survival and a higher complication rate than gastrectomies. On the other hand, they have better long-term outcomes than palliative procedures. However, MVRs are admissible when performed by an experienced surgical team in high-volume centers.

Abstract
Background: T4a gastric cancer (GC) is a subtype of advanced GC (AGC), which urgently needs a comprehensive grade method for better treatment strategy choosing. The purpose of this study was to develop two nomograms for predicting the prognosis of patients with T4a GC. Methods: A total of 1,129 patients diagnosed as T4a GC between 2010 and 2015 were extracted from the Surveillance, Epidemiology, and End Result (SEER) program database. Univariate and multivariate Cox analyses were performed to explore the independent predictors and to establish nomogram for overall survival (OS) of the patients, whereas competing risk analyses were performed to find the independent predictors and to establish nomogram for cancer-specific survival (CSS) of the patients. The area under the curve (AUC), calibration curve, decision curve analysis (DCA), and Kaplan–Meier analysis were performed to evaluate the nomograms. Results: Older age, larger tumor size, black race, signet ring cell carcinoma (SRCC), more lymph node involvement, the absence of surgery, the absence of radiotherapy, and the absence of chemotherapy were identified as independent prognostic factors for both OS and CSS. In the training cohort, the AUCs of the OS nomogram were 0.760, 0.743, and 0.723 for 1-, 3-, and 5-year OS, whereas the AUCs of the CSS nomogram were 0.724, 0.703, and 0.713 for 1-, 3-, and 5-year CSS, respectively. The calibration curve and DCA indicated that both nomograms can effectively predict OS and CSS, respectively. The abovementioned results were also confirmed in the validation cohort. Stratification of the patients into high- and low-risk groups highlighted the differences in prognosis between the two groups both in training and in validation cohorts. Conclusions: Age, tumor size, race, histologic type, N stage, surgery status, radiotherapy, and chemotherapy were confirmed as independent prognostic factors for both OS and CSS in patients with T4a GC. Two nomograms based on the abovementioned variables were constructed to provide more accurate individual survival predictions for them.

Abstract
INTRODUCTION In patients with gastric cancer, 6-27% of patients are diagnosed with T4b disease that invades adjacent organs, and curative resection can improve the prognosis of these patients. CASE PRESENTATION A 70-year-old Japanese man presented with an abdominal tumor and was diagnosed with advanced gastric cancer (L-Circ type 3 T4b N2 M0 H0 stage IVA, based on the 15th edition of the Japanese Classification of Gastric Carcinoma) with extensive abdominal wall invasion. We performed open gastrojejunal bypass for gastric obstruction and initiated a chemotherapeutic regimen comprising S-1 (120 mg/day) and oxaliplatin (100 mg/m2). Upper gastrointestinal endoscopy performed after the administration of six courses of the S-1 and oxaliplatin regimen revealed a persistent primary lower gastric wall lesion; however, the diameter of the abdominal wall invasion and metastatic lymph nodes was significantly reduced, in addition to decreased serum carcinoembryonic antigen and carbohydrate antigen 19-9 levels. Subsequently, the patient underwent distal gastrectomy with D2 lymphadenectomy combined with transverse colon and abdominal wall resection. We performed radical en bloc resection and achieved a tumor-free resection margin. Simple abdominal wall closure was performed without mesh or musculocutaneous flap placement. Histopathological examination of the resected tumor specimen showed direct invasion of the mesocolon and rectus abdominis muscle. The patient was postoperatively diagnosed with L Gre-Ant type5 T4b (SI: rectus abdominis muscle) N2 PM0 DM0 Stage IIIA R0 Grade 2a gastric cancer based on histopathological findings and received S-1 as adjuvant chemotherapy, 2 months postoperatively. No recurrence was detected 6 months postoperatively. CONCLUSIONS We report a case of advanced gastric cancer with extensive abdominal wall invasion that was successfully treated with gastrectomy combined with resection of adjacent organs showing tumor invasion after effective systemic chemotherapy. A therapeutic approach comprising curative surgery combined with perioperative chemotherapy is useful in patients with T4b gastric cancer.

Abstract
BACKGROUND Multivisceral resection may be the exclusive radical procedure for cT4b gastric cancer patients. However, most surgeons refuse to select surgery because of the theoretical higher mortality, morbidity and poorer prognosis. METHODS We retrospectively reviewed cT4b gastric cancer patients who underwent surgery from January 1,1997 to December 31,2018. The primary endpoint was overall survival. Short-term results and prognostic values of clinical and pathologic factors were also analyzed. RESULTS Patients underwent multivisceral resection had an acceptable mortality and morbidity. The overall 5-year survival rate of multivisceral resection was higher than that of palliative surgery (P < 0.05). And independent prognostic factors of multivisceral resection were R+ resection, extensive lymph node involved (>15), vascular cancer emboli, and postoperative chemotherapy. CONCLUSIONS cT4b gastric cancer patients underwent multivisceral resection experience acceptable mortality and morbidity. The independent prognostic factors for multivisceral resection were completeness of resection, extensive lymph node involvement (>15), vascular cancer emboli, and postoperative chemotherapy.

Abstract
Background For the treatment of locally advanced (T4) gastric cancer, extended multi-organ resection remains controversial. This study aimed to evaluate the surgical outcomes and survival of patients with T4 gastric cancer extending to the transverse colon. Methods A total of 2,652 gastric cancer patients underwent surgery between December 2011 and December 2015. Data from 40 of these patients who underwent curative resection for T4 gastric cancer extending to the transverse colon were obtained. Patient characteristics, related complications, long-term survival, and prognostic factors for T4 gastric cancer were analyzed. Results Postoperative morbidity occurred in 5 (12.5%) patients. All of the patients were cured with conservative treatment. No procedure-related mortality occurred. The 1-, 3-, and 5-year overall survival (OS) rates were 75.0%, 49.2%, and 36.9%, respectively, with a median survival time of 24 months. Univariate analysis revealed tumor size (P=0.049), advanced T stage (P=0.013), and lymph node metastasis (P=0.006) to be poor prognostic factors of OS. Advanced T stage and lymph node metastasis were identified by multivariate analysis as being independent prognostic factors. Further, it was observed that lymph node metastasis grade was associated with poorer OS. Conclusions Patients with T4 gastric cancer extending to the transverse colon might benefit from curative resection with acceptable morbidity and mortality.

Abstract
Gastric cancer perforations are rare events with management options ranging from lavage and perforation closure, to resection. Usual aim is to perform a damage control procedure, and very few patients are suitable for a curative resection. We report the first case of emergency gastrectomy with pancreatico-duodenectomy performed in emergency for a perforated stomach cancer with pancreatic head invasion. The patient was a 32-year-old gentleman who presented with a perforated antro-pyloric cancer with infiltration of pancreatic head. Emergency radical gastrectomy with en-bloc pancreatico-duodenectomy was performed with due considerations to the patient and disease factors. He had an uneventful postoperative recovery and remains disease free at 18 months of follow-up after having received adjuvant chemotherapy. Curative resections should be selectively offered in advanced (T4b) gastric cancers in patients without multiple adverse factors. In an emergency situation with perforation peritonitis, if the magnitude of resection is deemed unlikely to add to significant morbidity of the surgery, taking multiple factors into consideration, an R0 resection can offer a large survival benefit in such settings.

Abstract
INTRODUCTION Multivisceral resection (MVR) is potentially curative for selected gastric cancer patients, supposedly at the cost of increased complications. However, current data comparing MVR to standard gastrectomy (SG) is lacking. OBJECTIVES Compare complications and survival after MVR and SG. METHODS In a retrospective cohort of 1015 patients with gastric adenocarcinoma, 58 underwent MVR and 466 SG. Groups were compared concerning their characteristics, complications, and survival. RESULTS One hundred seventy-six patients had postoperative complications. Major complications were more frequent after MVR (P = .002). Surgical mortality was 8.6% and 4.9% for MVR and SG (P = .221). Older age, higher morbidities, and MVR were independent risk factors for major complications. The odds ratio for major complications was 5.89 for MVR with one or two organs and 38.01 for MVR with three or more organs. The pancreas was the most commonly removed organ and pT4b disease were confirmed in 34 (58.6%) of the MVR cases. Disease-free survival (DFS) was lower in MVR patients (51% vs 77.8%; P < .001), being worse according to the number of organs resected. In pN+ patients, DFS was worse after MVR. DFS was equivalent to pT4b and non-pT4b in the MVR group. CONCLUSIONS Increased morbidity and lower survival are expected for gastric cancer patients undergoing MVR.

Abstract
Background: To investigate prognostic factors and recurrence patterns in T4 gastric cancer (GC) patients after curative resection. Methods: Between January 2004 and December 2014, 249 patients with T4 gastric cancer undergoing curative resection were recruited. Patient characteristics, survival, prognostic factors and recurrence patterns were analyzed. Results: Our results showed that the median survival time (MST) for T4 gastric cancer after curative resection was 55.47 months, with 59.47 months for T4a (tumor perforating serosa) and 25.90 months for T4b (tumor invasion of the adjacent structure). Multivariate analysis indicated that age (hazard ratio [HR], 1.86; P = 0.006), location of tumor (HR, 1.25, 0.90 - 5.64; P < 0.001) and intraoperative blood loss (HR, 1.85; P = 0.010) were independent prognostic factors for overall survival (OS). After a median follow-up of 25.87 months, a total of 109 (43.8%) patients suffered from recurrence, and 90 patients had been observed specific recurrence sites, among which peritoneal metastasis was the most common recurrence pattern, 59.0% for T4a and 88.3% for T4b, respectively. Conclusions: For T4 gastric cancer patients after curative resection, older age, gastric cancer of the entire stomach and more intraoperative blood loss were associated with poor OS. The recurrence rate after curative resection for T4 was high, and the most common recurrence pattern was peritoneal metastasis.

Abstract
Background/Aims Peritoneal micrometastasis is known to play an important role in the recurrence of gastric cancer. However, its effects remain equivocal. Herein, we examine the messenger RNA (mRNA) as tumor markers, carcinoembryonic antigen (CEA), and cytokeratin 20 (CK20), in peritoneal washing fluid. Moreover, we evaluate whether these results could predict the recurrence of gastric cancer following curative resection. Methods We prospectively enrolled 132 patients with gastric cancers, who had received an operation, between January 2010 and January 2013. The peritoneal lavage fluid was collected at the operation field and semi-quantitative PCR was performed using the primers for CEA and CK20. We excluded patients with stage IA (n=28) early gastric cancer, positive cytologic examination of peritoneal washings (n=7), and those who were lost during follow up (n=18). Results A total of 79 patients with gastric cancers were enrolled, and the mean follow-up period was 39.95±19.25 months (range, 5-72 months). According to the multivariate analysis, T4 stage at the initial diagnosis was significantly associated with recurrence. All cases of recurrence were CEA positive and 6 cases were CK20 positive. The positive and negative predictive values of CEA were 32.0% and 100%, respectively, whereas those of CK20 were 37.5% and 71.4%, respectively. Disease free survival of CK20-negative cases was 36.17±20.28 months and that of CK20-positive cases was 32.06±22.95 months (p=0.39). Conclusions It is unlikely that the real time polymerase chain reaction results of mRNA for CEA and CK20 in peritoneal washing fluid can predict recurrence. However, negative results can convince surgeons to perform curative R0 resection.

Abstract
BACKGROUND The prognosis and survival of patients with advanced gastric cancer is poor. Although completeness of resection (R0) is one of the most important factors affecting survival, multivisceral resection (MVR) for locally advanced (clinical T4b, cT4b) gastric cancer remains controversial. The aim of this study was to evaluate the factors affecting prognosis and survival after MVR in patients with cT4b gastric cancer. METHODS Between 2005 and 2015, we retrospectively reviewed the medical records of 103 patients who underwent MVR for cT4b gastric cancer with suspected direct invasion to adjacent organs. Patient characteristics, related complications, long-term survival, and prognostic factors of cT4b gastric cancer were analyzed. RESULTS Postoperative mortality and morbidity rates of patients after MVR were 1.0 and 37.9%, respectively. R0 resection was achieved in 82.5% patients, all of whom had a significantly improved survival rate. Overall survival rates at 1 and 3 years were 78.3 and 47.7% for R0 resection and 46.6 and 14.3% for R1 resection, respectively (R0 vs. R1, P < 0.002). Multivariate analysis revealed that completeness of resection (R0) was an independent prognostic factor associated with longer survival. CONCLUSIONS In patients with cT4b gastric cancer, gastrectomy with MVR to achieve an R0 resection can be performed with acceptable postoperative morbidity and mortality rates and can have a positive impact on long-term survival.

Abstract
Background: Although the incidence of gastric (adenocarcinoma) cancer has been decreasing over time, it is still one of the most common malignancies worldwide, and proximal tumours tend to have a worse prognosis. Aim: To compare surgical outcomes and prognosis between proximal - excluding tumours of the cardia - and distal gastric cancer. Methods: Out of 293 cases reviewed - 209 with distal and 69 with proximal gastric cancer - were compared for clinical and pathological features, stage, surgical outcome, mortality and survival. Results: Statistically, there was no significant difference between patients in both groups regarding mortality (p=0.661), adjuvant chemotherapy (p 0.661), and radiation (p=1.000). However, there was significant difference in the degree of lymph node dissection employed (p=0.002) and the number of positive lymph nodes resected (p=0.038) between the two groups. The odds of death at five years for patients who had a D0 dissection was three times greater (odds ratio 2.78; (95%CI 1.33-5.82) than that for patients who had a D2 dissection, while for patients who had a D1 dissection the odds ratio was only 1.41 (95%CI 0.71-2.83) compared to D2-dissected patients. Conclusion: Although no significant differences were found between proximal and distal gastric cancer, the increased risk of death in D0- and D1-dissected patients clearly suggests an important role of radical D2 lymph node dissection in survival.

Abstract
BACKGROUND The prognostic factors which can improve the overall survival (OS) of patients with T4 gastric carcinoma (GC) are still controversial: a meta-analysis was conducted to analyze the impact of clinicopathological parameters on survival after MOR among patients with T4 GC. METHODS A systematic search was performed. Odd risks (ORs) of patients with T4 GC were used to calculate the relationship between clinicopathological parameters and OS. RESULTS Nine studies involving 941 patients with T4 GC were identified. Well-moderate differentiation led to increased 1-, 3-, 5-year OS with an OR of 2.63, 1.58 and 1.45. Borrmann type I-II led to increased 1-, 3-year OS with an OR of 1.67 and 2.08. No lymph node metastasis led to increased 1-, 3-, 5-year OS with an OR of 7.16, 3.18 and 3.71. Total gastrectomy led to increased 1-, 3-year OS with an OR of 2.01 and 1.79. ≥2 Organs resected led to increased 1-, 3-year OS with an OR of 2.19 and 2.19. TNM stage II-III led to increased 1-, 3-year OS with an OR of 3.68 and 5.75. Curative resection led to increased 1-, 3-, 5-year OS with an OR of 4.46, 5.80 and 5.98. CONCLUSION Well-moderate differentiation, Borrmann type I-II, no lymph node metastasis, total gastrectomy, ≥2 organs resected, TNM stage II-III and curative resection were positive prognostic factors for OS of patients with T4 GC.

Abstract
BACKGROUND Prognoses vary substantially among patients with advanced gastric cancer following curative surgery. The aim of the current study was to develop and verify the validity of a novel nomogram that predicts the probability of 5-year relapse-free survival (RFS) in patients who underwent curative resection for stage II/III gastric cancer. MATERIALS AND METHODS A nomogram to predict 5-year RFS following surgical resection of gastric cancer was constructed based on the data of patients who underwent surgery for primary gastric carcinoma at three institutions in Japan in January 2001-December 2006. Multivariate analysis using a Cox proportional hazards regression model was performed, and the nomogram's predictive accuracy (discrimination) and the agreement between observed outcomes and predictions (calibration) were evaluated by internal validation. RESULTS Multivariate analyses revealed that age at operation, depth of tumor, tumor location, lymph node classification, and presence of combined resection were significant prognostic factors for RFS. In the internal validation, discrimination of the developed nomogram for 5-year RFS was superior to that of the American Joint Committee on Cancer TNM classification (concordance indices of 0.80 versus 0.67; P < 0.001). Moreover, calibration appeared to be accurate. Based on these results, we have created free software to more easily predict 5-year RFS. CONCLUSION We developed and validated a nomogram to predict 5-year RFS after curative surgery for stage II/III gastric cancer. This tool will be useful for the assessing a patient's individual recurrence risk when considering additional therapy in clinical practice.

Abstract
OBJECTIVE To determine whether the gross tumor volume of resectable gastric adenocarcinoma on multidetector computed tomography could predict the presence of regional lymph node metastasis and could determine N categories. MATERIALS AND METHODS A total of 202 consecutive patients with gastric adenocarcinoma who had undergone gastrectomy 1 week after contrast-enhanced multidetector computed tomography were retrospectively identified. The gross tumor volume was evaluated on multidetector computed tomography images. Univariate and multivariate analyses were performed to determine whether the gross tumor volume could predict regional lymph node metastasis, and the Mann-Whitney U test was performed to compare the gross tumor volume among N categories. Additionally, a receiver operating characteristic analysis was performed to identify the accuracy of the gross tumor volume in differentiating N categories. RESULTS The gross tumor volume could predict regional lymph node metastasis (p<0.0001) in the univariate analysis, and the multivariate analyses indicated that the gross tumor volume was an independent risk factor for regional lymph node metastasis (p=0.005, odds ratio=1.364). The Mann-Whitney U test showed that the gross tumor volume could distinguish N0 from the N1-N3 categories, N0-N1 from N2-N3, and N0-N2 from N3 (all p<0.0001). In the T1-T4a categories, the gross tumor volume could differentiate N0 from the N1-N3 categories (cutoff, 12.3 cm3), N0-N1 from N2-N3 (cutoff, 16.6 cm3), and N0-N2 from N3 (cutoff, 24.6 cm3). In the T4a category, the gross tumor volume could differentiate N0 from the N1-N3 categories (cutoff, 15.8 cm3), N0-N1 from N2-N3 (cutoff, 17.8 cm3), and N0-N2 from N3 (cutoff, 24 cm3). CONCLUSION The gross tumor volume of resectable gastric adenocarcinoma on multidetector computed tomography could predict regional lymph node metastasis and N categories.

OBJECTIVE T-stage and N-stage have been proven to be the most important factors influencing survival in gastric cancer patients, and have been accepted for use in the Japanese Classification of Gastric Carcinoma (JCGC) and the Union International Cancer Control (UICC-TNM) staging systems. The purpose of this study was to compare the prognostic values of the different N classification systems in gastric cancer patients without serosal invasion. METHODS We retrospectively compared the clinicopathological results of 1,115 patients with primary gastric cancer who underwent curative gastric resection. RESULTS Serosal invasion was identified in 212 of 1,115 patients (19.0%), and it was associated with lymph node metastasis according to the JCGC(13th) (P<0.001) and TNM(7th) (P<0.001) systems. The 5-year survival rate for the serosal invasion-negative patients (78.2%) was significantly higher than that for the serosal invasion-positive patients (31.1%) (P<0.001). Multivariate Cox regression survival analysis showed that depth of invasion (P=0.013), 13(th) JCGC PN stage (P<0.001), and 7(th) TNM PN stage (P<0.001) were independent prognostic factors for serosal invasion-negative gastric cancer patients. CONCLUSIONS The prognosis of gastric cancer patients with serosal invasion is very poor. Both the 13(th) JCGC and 7(th) TNM N-staging systems were able to accurately estimate the prognosis of gastric cancer patients, but the 7(th) TNM system was simpler and easier to use.

Abstract
BACKGROUND The American Cancer Society projects there will be over 22,000 new cases, resulting in nearly 11,000 deaths, related to gastric adenocarcinoma in the US in 2014. The aim of the current study was to find clinicopathologic variables associated with disease-free survival (DFS) and overall survival (OS) following curative resection of gastric adenocarcinoma, and create a nomogram for individual risk prediction. METHODS A nomogram to predict DFS and OS following surgical resection of gastric adenocarcinoma was constructed using a multi-institutional cohort of patients who underwent surgery for primary gastric adenocarcinoma at seven major institutions in the US between January 2000 and August 2013. Discrimination and calibration of the nomogram were tested by C-statistic, Kaplan-Meier curves, and calibration plots. RESULTS A total of 719 patients who underwent surgery for primary gastric adenocarcinoma were included in the study. Using the backward selection of clinically relevant variables with Akaike information criteria, age, sex, tumor site, depth of invasion, and lymph node ratio (LNR) were selected as factors predictive of OS, while age, tumor site, depth of invasion, and LNR were incorporated in the prediction of DFS. A nomogram was constructed to predict OS and DFS using these variables. Discrimination and calibration of the nomogram revealed good predictive abilities (C-index, DFS 0.711; OS 0.702). CONCLUSION Independent predictors of recurrence and death following surgery for primary gastric adenocarcinoma were used to create a nomogram to predict DFS and OS. The nomogram was able to stratify patients into prognostic groups, and performed well on internal validation.

Abstract
Although, gastric cancer is quite common in Korea, the treatment outcome is relatively favorable compared to that of Western countries. However, there is no Korean multidisciplinary guideline for gastric cancer and thus, a guideline adequate for domestic circumstances is required. Experts from related societies developed 22 recommendation statements for the diagnosis (n=9) and treatment (n=13) based on relevant key questions. Evidence levels based on systematic review of literatures were classified as five levels from A to E, and recommendation grades were classified as either strong or weak. The topics of this guideline cover diagnostic modalities (endoscopy, endoscopic ultrasound, radiologic diagnosis), treatment modalities (surgery, therapeutic endoscopy, chemotherapy, radiotherapy) and pathologic evaluation. External review of the guideline was conducted at the finalization phase.

Abstract
Objective To evaluate surgical outcomes and prognostic factors for T4 gastric cancer treated with curative resection. Methods Between January 1994 and December 2008, 94 patients diagnosed with histological T4 gastric carcinoma and treated with curative resection were recruited. Patient characteristics, surgical complications, survival, and prognostic factors were analyzed. Results Postoperative morbidity and mortality were 18.1% and 2.1%, respectively. Multivariate analysis indicated lymph node metastasis (hazard ratio, 2.496; 95% confidence interval, 1.218–5.115; p = 0.012) was independent prognostic factor. Conclusions For patients with T4 gastric cancer, lymph node metastasis was associated with poorer survival. Neoadjuvant chemotherapy or aggressive adjuvant chemotherapy after radical resection was strongly recommended for these patients.

Abstract
OBJECTIVE The objective of our study was to assess the clinical feasibility of diffusion-weighted (DW) magnetic resonance (MR) imaging in preoperative T staging of gastric cancer prospectively. METHODS Forty-five patients underwent axial T2-weighted (T2W) and DW (b, 0 and 1000 seconds/mm) MR imaging. Two radiologists interpreted the images for detection and staging of the tumors independently. The McNemar test was used to check differences in diagnostic accuracy with the reference of postoperative histopathological results. RESULTS Diffusion-weighted and T2W images detected 44 and 42 of 45 histologically confirmed lesions, respectively. Furthermore, DW images detected 11 of 12 pT1 lesions compared to 9 of 12 lesions by T2W images. The staging accuracy of advanced gastric cancer (≥pT2) in DW imaging is significantly higher than that in T2W imaging (87.9% and 69.7%, respectively; P < 0.05). CONCLUSIONS Diffusion-weighted is superior to T2W imaging in detection of early gastric cancers (pT1) and staging advanced cancers (≥pT2).

Abstract
Although gastric cancer is quite common in Korea, the treatment outcome is relatively favorable compared to those in western countries. However, there are currently no Korean multidisciplinary guidelines for gastric cancer. Experts from related societies developed guidelines de novo to meet Korean circumstances and requirements, including 23 recommendation statements for diagnosis (n=9) and treatment (n=14) based on relevant key questions. The quality of the evidence was rated according to the GRADE evidence evaluation framework: the evidence levels were based on a systematic review of the literature, and the recommendation grades were classified as either strong or weak. The applicability of the guidelines was considered to meet patients' view and preferences in the context of Korea. The topics of the guidelines cover diagnostic modalities (endoscopy, endoscopic ultrasound, and radiologic diagnosis), treatment modalities (surgery, therapeutic endoscopy, chemotherapy, and radiotherapy), and pathologic evaluation. An external review of the guidelines was conducted during the finalization phase.

Abstract
Objective: Combined resection for locally advanced (T4) gastric cancer may result in high morbidity and mortality. The aim of this study was to evaluate the clinicopathologic characteristics to determine the prognostic factors for T4 gastric cancers. Methodology: A total of 463 consecutive patients with gastric cancers were enrolled in this study. Among them, 63 patients received combined resections. Various clinicopathologic factors influencing survival rates were evaluated. Survival rates were calculated according to the Kaplan-Meier method. Prognostic factors were evaluated by the univariate and multivariate analysis. Results: Thirty-one patients (49.2%) received one additional organ resection and 32 patients (50.8%) received two or more additional organ resections. Curative resection was performed in 49 patients (77.8%). Multivariate analysis identified curative resection (hazard ratio 0.330; 95 percent confidence interval, 0.139-0.784; P = 0.012) and tumor diameter (> 7 cm) (hazard ratio, 3.589; the 95 percent confidence interval, 1.425-9.037; P = 0.007) as independent prognostic factor for patients with T4 gastric cancer undergoing combined resection. Conclusions: The use of aggressive multi-organ resection was recommended for patients with T4 gastric carcinoma, with tumor diameter as a useful indicator. Patients with relatively small tumor diameter (≤ 7cm) could benefit from multi-organ resections.

Abstract
OBJECTIVE The purpose of our study was to evaluate CT findings to differentiate between T4a and less advanced gastric cancers. METHODS The institutional review board approved this study and waived informed consent. This study included 228 retrospectively identified patients with surgically confirmed gastric cancer (138 T1, 25 T2, 24 T3 and 41 T4a) and who had also undergone pre-operative CT scan. Transverse and multiplanar reconstruction scans were reviewed in consensus by two other blinded radiologists. The following CT findings that differentiate T4a from less advanced cancers were evaluated: nodular or an irregular outer layer of the gastric wall, haziness of the perigastric fat and a hyperattenuating serosa sign. The CT features of T4a and less advanced gastric cancers were compared by means of univariate and multivariate analyses. RESULTS In univariate analysis, nodular or an irregular outer layer of the gastric wall, haziness of the perigastric fat and the hyperattenuating serosa sign were significant in differentiation between T4a and less advanced gastric cancers. In addition, nodular or an irregular outer layer of the gastric wall and the hyperattenuating serosa sign were significant in differentiation between T3 and T4a. In multivariate logistic analysis, the hyperattenuating serosa sign was the most significant finding in differentiation between T3 and T4a (odds ratio, 4.210; 95% confidence intervals, 1.581-11.214; p=0.004). CONCLUSION The hyperattenuating serosa sign may be a useful CT finding in differentiation between T4a and less-advanced gastric cancers. ADVANCES IN KNOWLEDGE The hyperattenuating serosa sign is associated with gastric cancer with invading the serosa and can facilitate planning of the optimal pre-operative evaluation and treatment.

Abstract
BACKGROUND The purpose of this study was to clarify the surgical indications for gastrectomy combined with distal or partial pancreatectomy (GP) in patients with gastric cancer. METHODS From January 1994 to December 2009, 29 patients with primary gastric cancer surgically invading the pancreas without distant organ metastasis underwent GP for R0 resection. The patients' characteristics, surgical data, and clinicopathological features were used for the analysis of survival and prognostic factors. RESULTS The median disease-free survival and median survival time (MST) of all patients were 15 and 30 months, respectively. Only pN3 status (characterized by 7 or more pathologically metastatic lymph nodes) according to the Japanese Classification of Gastric Carcinoma, 14th edition, was shown to be a prognostic factor in a multivariate analysis. The MST of the patients with pN3 and the other patients were 12 and 51 months, respectively (p < 0.001). CONCLUSIONS We suggest that pancreas invasion should not be considered a contraindication for gastrectomy and that patients with a small number of lymph node metastases (six or fewer) might be candidates for GP in the case of gastric cancer that requires pancreatectomy for R0 resection.

Abstract
To establish a safe, long-term regimen of docetaxel (DOC) and cisplatin (CDDP) in an outpatient setting for gastric cancer refractory to S-1 adjuvant chemotherapy, a dose-escalating phase I study was conducted. Cohorts of patients were treated with escalating doses of DOC (starting at 20 mg/m² per week with 5 mg/m² increments) and a fixed dose of CDDP (25 mg/m²). Drugs were administered on days 1, 8, and 15. A cycle of this treatment was 28 days. In total, 52 courses were performed, and the mean number of courses was 5.3. Two of the four patients at dose level 3 showed dose-limiting toxicities (grade 4 neutropenia, and grade 3 anorexia and dehydration). The recommended dose (RD) of DOC was therefore defined as 25 mg/m². There is a need for a phase II clinical trial using this regimen in patients with S-1-refractory stage II/III gastric cancer.

Direct liver invasion from a gastric adenocarcinoma as an initial presentation of extranodal tumor spread. Case Rep Med 2012; 2012:651232. [PMID: 22761626 PMCID: PMC3384973 DOI: 10.1155/2012/651232] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2012] [Revised: 05/06/2012] [Accepted: 05/10/2012] [Indexed: 12/24/2022] Open
Abstract
Gastric cancer often carries a poor prognosis, with an estimated 740,000 deaths from the malignancy occurring yearly worldwide (Dicken et al., 2005). The mortality of disease is largely dependent on the extent of tumor spread, as gastric cancer has a predilection to metastasize to other visceral secondaries via hematogenous and lymphatic dissemination. Direct invasion of a gastric adenocarcinoma to adjacent organs secondary to gastric wall perforation does occur; however, it is often present in the setting of advanced disease. Rarely does direct tumor invasion to adjacent organs from a gastric adenocarcinoma present as the initial manifestation of extranodal tumor spread. We present a case of a 40-year-old male with direct tumor extension to the liver as an initial presentation of extranodal tumor spread from a gastric adenocarcinoma. Clinicians should be aware of such an occurrence, as treatment modalities in direct liver extension from a gastric adenocarcinoma vary and may be directed towards palliation rather than curative intent.

Abstract
To investigate the progress in evidence-based surgical treatment of non-metastatic gastric cancer, we reviewed the last ten years’ literature. The data used in this review were identified by searches made on MEDLINE, Current Contents, PubMed, and other references taken from relevant original articles (on prospective and retrospective studies) concerning gastric cancer surgery. Only papers published in English between January 1999 and December 2009 were selected. Data from ongoing studies were obtained in December 2009, from the trials registry of the United States National Institutes of Health (http://www.clinicaltrial.gov). The citations list was presented according to evidence based relevance (i.e., randomized controlled trials, prospective studies, retrospective series). In the last ten years, many challenges have been faced relating to the extension of gastric resection and nodal dissection as well as surgical timing, but we found only limited evidence, regardless of latitude of study. The ongoing phase-III trials may provide answers that will be valid for the coming decades, and which may bring definitive answers for the currently unresolved questions.

Abstract
BACKGROUND Extended multiorgan resection (EMR) for locally advanced (T4) gastric cancer remains controversial. The aim of this study was to evaluate the effectiveness of this approach with regard to morbidity, mortality, and survival. METHODS Between 2005 and 2009, 41 patients underwent aggressive surgery for clinical T4 gastric cancer. Univariate and multivariate analyses were used to identify prognostic factors for surgical outcomes and survival in these patients. RESULTS Curative resection was performed in 29 patients (70.7%); postoperative morbidity and mortality rates were 17.1% and 4.9%, respectively. The survival rate in R0 resection patients was significantly longer than that in patients undergoing R1 or R2 resection. Multivariate analysis identified resectability and tumor size (≥10 cm) as independent prognostic factor for patients with T4 gastric cancer undergoing combined resection. CONCLUSIONS EMR should be performed for patients with T4 gastric cancer in whom curative resection can be used.

Abstract
AIM: To investigate the prognostic factors of T4 gastric cancer patients without distant metastasis who could undergo potentially curative resection.
METHODS: We retrospectively analyzed the clinical data of 71 consecutive patients diagnosed with T4 gastric cancer and who underwent curative gastrectomy at our institutions. The clinicopathological factors that could be associated with overall survival were evaluated. The cumulative survival was determined by the Kaplan-Meier method, and univariate comparisons between the groups were performed using the log-rank test. Multivariate analysis was performed using the Cox proportional hazard model and a step-wise procedure.
RESULTS: The study patients comprised 53 men (74.6%) and 18 women (25.4%) aged 39-89 years (mean, 68.9 years). Nineteen patients (26.8%) had postoperative morbidity: pancreatic fistula developed in 6 patients (8.5%) and was the most frequent complication, followed by anastomosis stricture in 5 patients (7.0%). During the follow-up period, 28 patients (39.4%) died because of gastric cancer recurrence, and 3 (4.2%) died because of another disease or accident. For all patients, the estimated overall survival was 34.1% at 5 years. Univariate analyses identified the following statistically significant prognostic factors in T4 gastric cancer patients who underwent potentially curative resection: peritoneal washing cytology (P < 0.01), number of metastatic lymph nodes (P < 0.05), and venous invasion (P < 0.05). In multivariate analyses, only peritoneal washing cytology was identified as an independent prognostic factor (HR = 3.62, 95% CI = 1.37-9.57) for long-term survival.
CONCLUSION: Positive peritoneal washing cytology was the only independent poor prognostic factor for T4 gastric cancer patients who could be treated with potentially curative resection.

Abstract
BACKGROUND Surgical outcomes of multiorgan resection (MOR) for T4 gastric carcinoma reported in the literature are widely variable. We herein report a large surgical series of T4 gastric carcinoma. METHODS One hundred seventy-nine patients with cT4 gastric carcinoma were recruited onto the study. Patient characteristics, surgical strategy and related complications, long-term survival, and prognostic factors of T4 gastric carcinoma were analyzed. RESULTS Of 179 cT4 gastric carcinoma, there were 57 cT4 (pT3) with MOR, 91 pT4 with MOR, and 31 cT4 without MOR. pT4 with MOR were more likely to be associated with nodal metastasis, cellular dedifferentiation, and lymphoperineural infiltration compared to those of pT0-3 (P < 0.01 for all). For 91 pT4 with MOR, their surgical mortality and morbidity rates were 4.4 and 28.6%, respectively; their 1-, 3-, and 5-year overall survival rates were 55.2, 22.4, and 12.2%, respectively. The long-term survival of cT4 (pT3) with MOR was superior to pT4 with MOR (P = 0.006) and cT4 without MOR (P = 0.004). There was a striking difference between pT4 with MOR, R0 and pT4 with MOR, and R1 or R2 (P = 0.007). By means of multivariate analysis, lymph node status, liver invasion, and positive surgical margin were independent prognostic factors. CONCLUSIONS Aggressive surgical management of pT4 gastric carcinoma should be limited to patients without adverse prognostic factors such as advanced nodal involvement and pancreatic invasion.

Abstract
OBJECTIVE The stomach is suspended in the abdominal cavity by perigastric ligaments, which are derived from the dorsal and ventral mesogastrium. These ligaments provide a direct contiguous pathway for the peritoneal spread of gastric cancer. In this article, we discuss the embryology and anatomy of the stomach and describe the specific ligamentous routes along which gastric cancers may spread by direct invasion. CONCLUSION Extragastric disease alters the prognosis and treatment options available to patients with gastric cancer. Familiarity with the stomach's embryology will help the radiologist understand its anatomy and, therefore, the patterns of regional spread of gastric cancer. The location of the primary tumor can predict involvement of specific perigastric ligaments because locoregional spread of gastric cancer occurs along the arteries, veins, nerves, and lymphatic channels within those ligaments. Thus, identifying the location of the primary tumor can potentially improve patient outcomes.

Abstract
Gastric carcinoma is one of the most frequent malignancies in the world and its clinical behavior especially depends on the metastatic potential of the tumor. In particular, lymphatic metastasis is one of the main predictors of tumor recurrence and survival, and current pathological staging systems reflect the concept that lymphatic spread is the most relevant prognostic factor in patients undergoing curative resection. This is compounded by the observation that two-thirds of gastric cancer in the Western world presents at an advanced stage, with lymph node metastasis at diagnosis. All current therapeutic efforts in gastric cancer are directed toward individualization of therapeutic protocols, tailoring the extent of resection and the administration of preoperative and postoperative treatment. The goals of all these strategies are to improve prognosis towards the achievement of a curative resection (R0 resection) with minimal morbidity and mortality, and better postoperative quality of life.

Abstract
BACKGROUND AND OBJECTIVES One of the sites most frequently invaded by gastric cancer is the mesocolon; however, the UICC does not mention this anatomical site as an adjacent structure involved in gastric cancer. The purpose of this study was to characterize and classify mesocolon invasion from gastric cancer. METHODS We examined 806 patients who underwent surgery for advanced gastric carcinoma from 1992 to 2007 at the Department of Surgery, Gangnam Severance Hospital, Korea. Among these, patients who showed macroscopically direct invasion into the mesocolon were compared to other patients with advanced gastric cancer. RESULTS The curability, number and extent of nodal metastasis, and the survival of the mesocolon invasion group were significantly worse than these factors in the T3 group. However, the survival of the mesocolon invasion group after curative resection was much better than that of patients who had incurable factors. CONCLUSIONS Mesocolon invasion should be included in T4 for the staging of gastric cancer.

Abstract
PURPOSE In locally advanced gastric carcinomas that have invaded adjacent organs, the prognosis is poor. When combined resections are performed in T4 gastric cancers, a high morbidity rate is reported and it is inconclusive as to whether or not there is an improvement in the survival rate. We investigated surgical outcomes and analysed the prognostic factors for T4 gastric cancers. PATIENTS AND METHODS Between January 1992 and December 2000, 132 patients underwent surgery for T4 gastric cancer; they were divided into three groups: combined resections in group I, gastrectomy alone in group II, and resections not performed but palliative gastrojejunostomy or intraperitoneal chemotherapy in group III. Surgical outcomes and clinicopathologic factors were compared and prognostic factors were evaluated. RESULTS Among the three groups, statistically significantly different factors were tumour location, Borrmann type, tumour size, distant metastasis and peritoneal metastasis. The most commonly resected organ was the transverse colon, and 14 post-operative morbidities developed. In the multivariate analysis, the treatment group and curability were proved to be independent prognostic factors. CONCLUSION In patients with T4 gastric carcinoma, an aggressive surgical approach can be beneficial when curative resection is performed. If curative resection is not possible, palliative resection can be performed for a better quality of life.

Abstract
PURPOSE This study was undertaken to compare the accuracy of magnetic resonance (MR) imaging and 64-slice multidetector computed tomography (64-MDCT) in the T staging of gastric carcinoma in comparison with histopathology. MATERIALS AND METHODS Forty patients with an endoscopic diagnosis of gastric carcinoma underwent preoperative MR imaging and 64-MDCT, both of which were performed after i.v. injection of scopolamine and water distension of the stomach. In the MR imaging protocol, we acquired T2-weighted turbo spin-echo (TSE) sequences, true fast imaging steady-state free precession (true-FISP) and gadolinium-enhanced T1-weighted volumetric interpolated breath-hold examination (VIBE) 3D sequences. Contrastenhanced CT scans were obtained in the arterial and venous phases. Two groups of radiologists independently reviewed the MR and 64-MDCT images. The results were compared with pathology findings. RESULTS In the evaluation of T stage, 64-MDCT had 82.5% and MR imaging had 80% sensitivity. Accuracy of MR imaging was slightly higher than that of 64-MDCT in identifying T1 lesions (50% vs 37.5%), whereas the accuracy of 64-MDCT was higher in differentiating T2 lesions (81.2% vs 68.7%). The accuracy of MR imaging and 64-MDCT did not differ significantly in the evaluation of T3-T4 lesions (p>0.05). Understaging was observed in 20% of cases with MR imaging and in 17.5% with 64-MDCT. CONCLUSIONS MR imaging and 64-MDCT accuracy levels did not differ in advanced stages of disease, whereas MR imaging was superior in identifying early stages of gastric cancer and can be considered a valid alternative to MDCT in clinical practice.

Abstract
BACKGROUND AND OBJECTIVES Proper patient selection for multi-organ resection in T4 gastric carcinoma remains controversial. Our aim was to investigate which patients might benefit from multi-organ resection. METHODS Among 1,775 consecutive patients receiving gastric cancer surgery, 71 had adjacent organ invasion. Short- and long-term surgical outcomes and associations between clinicopathological factors and overall survival were investigated. RESULTS Forty-seven patients underwent curative surgery with multi-organ resection, and 24 underwent non-curative surgery, with or without multi-organ resection. Postoperative morbidity and mortality rates were 31.7% and 3.3%, respectively. Patients receiving curative surgery via multi-organ resection survived longer than those without (MST, 31.5 months vs. 19.1 months, P = 0.046). Multi-organ resection did not affect survival when performed in non-curative surgery. N3 lymph node metastasis was an independent prognostic factor for poor outcome (HR = 3.89, 95% CI = 1.40-10.83) in curatively resected patients; patients with N3 lymph node metastasis showed similar survival to patients receiving non-curative surgery. CONCLUSION Multi-organ resection should be performed only when no incurable factors are present, and R0 resection is most likely. Multi-organ organ resection does not, however, seem to be effective in patients with N3 lymph node metastasis, even when curative resection is performed.

Abstract
BACKGROUND Although the mortality for gastric cancer is decreasing in Western Europe and United States, it still remains high in Eastern Europe. This study was aimed at evaluating short- and long-term results of surgical treatment of gastric cancer performed in Latvia Oncology Center. METHODS Retrospectively collected data from 461 patients who underwent gastrectomy with curative intent in Latvia Oncology Center from January 2001 to December 2005 were analyzed statistically. RESULTS An average (range) of 92.2 (81-102) R0-R1 gastrectomies was performed each year. Post-operative complications occurred in 75 patients (16.3%); in-hospital mortality was 3.3%. The overall 5-year survival was 50.8%. In 444 cases (96.3%) there was histopathologic confirmation of R0-resection with a 5-year survival of 52.5% (P<0.001). Considering pT category, 5-year survival was 88.6% for pT1 patients, 65% for pT2, 42.3% for pT3 and 27% for pT4 (P<0.001). Considering pN category, 5-year survival was 67% for pN0 patients, 30% for pN1 and 29% for pN2-3 (P<0.001). CONCLUSIONS Clinico-pathologic characteristics of patients who underwent resection with curative intent are comparable to other Western experiences. Short- as well as long-term results are also similar if not for pN+ patients where no difference between pN1 and pN2 cases was observed.
