Reappraise role of lymph node status in patterns of recurrence following curative resection of gastric adenocarcinoma. Chin J Cancer Res 2021; 33:331-342. [PMID: 34321830 PMCID: PMC8286896 DOI: 10.21147/j.issn.1000-9604.2021.03.05] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2021] [Accepted: 05/10/2021] [Indexed: 12/24/2022] Open
Abstract
Objective To examine the association between lymph node status and recurrence patterns in completely resected gastric adenocarcinoma. Methods We retrospectively assessed 1,694 patients who underwent curative gastrectomy from January 2010 to August 2014. Patients stratified according to lymph node status and recurrence patterns among different subgroups were compared. Results Of all, 517 (30.5%) patients developed recurrent disease, and complete data of recurrence could be obtained in 493 (95.4%) patients. For pN0 patients, the patterns of recurrence were different according to pT stage: locoregional recurrence was most common in patients with pT1−2 disease (57.1%), distant recurrence was most common in patients with pT3 disease (57.1%), and peritoneal recurrence was most common in patients with pT4a disease (66.7%). For pN+ patients, distant metastasis was most common pattern irrespective of pT stage. The site-specific trend of recurrence showed that locoregional recurrence increased within 5 years in patients with pN0−2 disease but plateaued 3 years after surgery in patients with pN3 disease. Time to recurrence was significantly longer for the pN0 patients compared with the pN+ patients (median: 25 vs. 16 months, P=0.001). Moreover, post-recurrence survival was significantly better for the pN0 patients than for the pN+ patients (median: 12 vs. 6 months, P<0.001), especially in patients with non-peritoneal recurrence, late recurrence, single recurrence, and receipt of potential curative treatment.
Conclusions Among clinicopathologic factors, lymph node status is the most important factor associated with recurrence patterns after curative gastrectomy. Lymph node status may be used as an adjunct in clinical decision-making about postoperative therapeutic and follow-up strategies.

Abstract
Purpose Regional lymph node recurrence (RLNR) in gastric cancer is uncommon. We investigated the effects of radiotherapy combined with chemotherapy against limited RLNR and analyzed the regularity of regional lymph node recurrence and metastasis. Patients and Methods This retrospective study included 34 gastric cancer patients with limited RLNR after D2 lymphadenectomy between January 2012 and May 2018. All patients received systemic chemotherapy and local radiotherapy with median dose of 52.5 Gy (30–66 Gy in fractions of 1.8–3.0 Gy daily, five times weekly). All sites of recurrent and metastatic lymph nodes were collected and analyzed. Results The median follow-up was 19 months (range 7–60 months). After treatment, complete response and partial response were observed in 32.4% and 55.9% of patients, respectively. The median overall survival (OS) and progression-free survival (PFS) were 18 months and 13 months. On multivariate analysis, age (≤60 vs >60) was associated with a significantly better OS (p = 0.025) and radiation dose (<54 Gy vs ≥54 Gy) was considered as an independent prognostic factor for PFS (p = 0.000). During radiotherapy, three patients developed grade 3 gastrointestinal toxicity, and no deaths were related to the treatments. The most commonly metastatic lymph nodes were the No. 4, No. 3, No. 6, No. 5, No. 7, No. 9, and No. 8 nodes; the recurrent lymph nodes were mainly located in the No. 16b, No. 16a, No. 9, No. 14, No. 7, No. 13, and No. 8 nodes. Conclusion The selected gastric cancer patients with limited RLNR may benefit from radiotherapy combined with chemotherapy. High-dose radiotherapy (≥54 Gy) lead to better PFS and tend to extend OS. The major lymph node recurrence sites were in the gastric vascular region (especially No. 16a/b nodes).

Abstract
Gastric cancer is the third most common cause of cancer related death. Although its incidence is globally declined, prognosis remains dismal in the Western hemisphere, while better outcomes are evidenced in Asian countries. Endoscopic or surgical resection with or without lymphadenectomy represents the only chance of cure, with limited improvements of the prognosis in case of associated chemotherapy in a neoadjuvant or adjuvant setting. This could be mainly attributed to the uniform fashion of treatment of gastric cancer, mainly based on the histological features, that usually do not reflect the complexity of the disease. With the recent introduction of genomic technologies and new generation sequencing techniques, gastric cancer biology is now investigated in great details. This has brought to the publication of three main molecular classifications, based on the underlying molecular biology of gastric cancer. Although only few clinical reports are currently present in literature, the identification of gastric cancer molecular subtypes has shown interesting findings that may pave the way to a tailored clinical and surgical management. The aim of this review is, thus, to give a comprehensive overview of the current molecular classifications as compared to the available histopathological ones, also focusing on the potential clinical and surgical benefits and the future perspectives for a more personalized treatment of gastric cancer.

Abstract
BACKGROUND Greater lymph node retrieval in gastric cancer improves staging accuracy and may improve survival from increased clearance of nodal micrometastasis. This retrospective cohort study investigated if more lymph nodes removed in gastric cancer increases survival and if such effect is stage-specific due to differential risks of nodal micrometastasis and systemic disease. METHODS The prospectively collected database of curatively resected gastric cancer patients in National Cancer Center, South Korea between 2000 and 2009 was reviewed. Disease-free survival (DFS) and overall survival (OS) for all patients and for each stage according to number of lymph nodes examined (1-30, 31-45, > 45) were analyzed. RESULTS Of 4049 patients, 96.6% and 98.4% underwent D2 (perigastric and extragastric) lymphadenectomy and had ≥ 15 lymph nodes examined. Mean number of nodes examined was 43. Five-year OS & DFS rates were 83.3% and 80.7%. Patients with > 45 nodes examined had significantly lower DFS (p = 0.002) and OS (p = 0.007) compared to those with 1-30 and 31-45 nodes. However, proportion of patients with > 45 nodes examined increased with stage (p = 0.0005). Per stage, there was no significant difference in DFS and OS according to number of nodes examined except for stage IIIA favoring more nodes (p = 0.018 and p = 0.044, respectively). Similar trend was seen in stage IIB. Number of examined nodes positively correlated with number of pathologic nodes for all patients (r = 0.144, p < .001) but not for stage IIB and IIIA. Number of nodes examined was a significant survival predictor in stage IIIA. CONCLUSION Greater lymph node harvest showed improved survival in intermediate-stage gastric cancer.

Abstract
OBJECTIVE To investigate the association between preoperative lymph node size (Ns) and prognosis of radical gastrectomy for gastric cancer. METHODS The clinical and pathological data of 970 patients undergoing radical gastrectomy for gastric cancer were retrospectively analyzed. The correlation between Ns and the identified variables for the prediction of overall survival (OS) and disease-free survival (DFS) was examined. RESULTS Three hundred and thirty-one (34.1%) of 970 patients developed recurrence, which was most commonly in local lymph nodes. The average Ns was 1.52 cm in patients with recurrence, which was significantly higher than the 1.14 cm observed in patients without recurrence (p < 0.001). Patients were categorized into three groups as follows (Ns category):Ns0:≤1.10 cm, Ns1:1.10-1.70 cm, and Ns2:>1.70 cm, determined using the X-tile program. In univariate and multivariate analyses, Ns category, age, tumor size, lymphadenectomy, adjuvant chemotherapy and TNM stage were independent prognostic factors for DFS. Stratified analysis only in stage III was there a significant difference in the Ns category based on TNM stage. Furthermore, in the stage III subgroup, univariate and multivariate analyses revealed that Ns category, lymphadenectomy, and TNM stage was independent prognostic factors for DFS. A nomogram were developed to predict the 3-year DFS rate. CONCLUSIONS Preoperative Ns is an independent prognostic factor for DFS of patients after radical surgery for gastric cancer. The proposed nomogram combined with Ns could be a simple and effective approach to predict the 3-year DFS of stage III patients.

Early gastric cancer metastasizing to the rectum, possibly via a hematogenous route: a case report and review of literature. Surg Case Rep 2016; 2:58.

Abstract
BACKGROUND The most common pattern of recurrence of gastric cancer (GC) is peritoneal dissemination. However, rectal metastasis via hematogenous or lymphatic spread is exceedingly rare. We present a case of a 65-year-old man with an intramucosal GC who developed a rectal recurrence, possibly via a hematogenous route. CASE PRESENTATION A 65-year-old man underwent curative endoscopic submucosal dissections for the intramucosal GCs at the anterior wall of the fornix twice. The third GC at the similar location was treated by radical laparoscopic proximal gastrectomy; microscopic examination revealed well-differentiated tubular adenocarcinoma confined to the lamina propria mucosae (T1aN0M0, stage IA). Follow-up colonoscopy revealed a 30-mm submucosal mass in the rectal wall 2 years later, and a metastasis of gastric origin was suspected histopathologically. After a staging laparoscopy confirmed the absence of findings suggestive of serosal involvement or peritoneal dissemination, including negative peritoneal washing cytology, a laparoscopic low anterior resection with lymph node dissection was performed. Microscopically, the tumor was found to mainly be located in the submucosal layer and showed features of moderately differentiated tubular adenocarcinoma. The serosal surface was free of disseminated tumor. Lymph node metastases were identified. Immunohistochemically, there were foci of carcinoma cells that were positive for cytokeratin 20; however, they were negative for cytokeratin 7. Negative staining for caudal-type homeobox 2, a transcription factor indicating goblet cell differentiation, combined with absence of intramucosal carcinoma in the rectal mucosa, suggested a diagnosis of metastatic adenocarcinoma of gastric origin. The absence of evidence of peritoneal dissemination suggested hematogenous or lymphatic spread. CONCLUSION Although rectal metastasis from GC, particularly when attributable to hematologic or lymphatic metastasis, is very rare, metastatic gastric adenocarcinoma should be considered as a differential diagnosis for patients who present with a rectal tumor and a past history of GC, even if it is an early GC.

Docetaxel, capecitabine and concurrent radiotherapy for gastric cancer patients with postoperative locoregional recurrence. TUMORI JOURNAL 2015; 101:433-9. [PMID: 25983095 DOI: 10.5301/tj.5000336] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 01/14/2015] [Indexed: 11/20/2022]
Abstract
AIMS AND BACKGROUND This study aimed to assess the efficacy of concurrent chemoradiotherapy (CCRT) with docetaxel and capecitabine versus docetaxel and capecitabine chemotherapy for gastric cancer patients with postoperative locoregional recurrence. METHODS From 2008 to 2011, 81 patients with locoregional recurrence after curative resection of gastric cancer were enrolled. Thirty-nine (CCRT group) received involved-field radiotherapy with oral capecitabine (twice daily, 5 days/week) and intravenous infusion of docetaxel (once weekly). The remaining 42 patients (chemotherapy group) were treated with oral capecitabine (twice daily, days 1-14) followed by intravenous infusion of docetaxel (days 1 and 8). The overall response rate, overall symptom control rate, toxicity or adverse reactions, and overall survival (OS) were compared. RESULTS The overall response rate (CR+PR) was significantly higher in the CCRT group (79.5%) than the chemotherapy group (54.8%). In CCRT individuals, the control rates for bleeding, pain, and dysphagia/obstruction were 87.5%, 75%, and 71.4%, respectively, versus 63.2%, 50%, and 28.6% in the chemotherapy group. CCRT patients had a better symptom control rate than the chemotherapy group (52.5% vs. 80%). Adverse reactions were nonsignificantly more severe in CCRT patients. Finally, median OS was longer in the CCRT vs. chemotherapy group (14.2 vs. 6.4 months). CONCLUSIONS Involved-field radiotherapy with docetaxel and capecitabine was effective and well tolerated. These findings provide further insight into the role of CCRT in gastric cancer. However, this was not a randomized controlled study and the number of patients was relatively small, suggesting that cautious interpretation of cumulative estimates is warranted.

Abstract
BACKGROUND This study aimed to validate the prognostic relevance of macroscopic serosal changes in patients with resected gastric cancer. Prospectively collected databases of two multicenter randomized phase III trials of adjuvant chemotherapy were analyzed. METHODS For this study, 655 patients in the control groups of AMC 0101 and 0201 trials were selected. Macroscopic serosal changes were determined according to disruptions in serosal continuity, such as changes in color or nodular texture by the operating surgeon. Correlations with recurrence-free survival (RFS), overall survival (OS), and time to peritoneal recurrence were analyzed. RESULTS Macroscopic serosal changes were identified intraoperatively in 432 patients (66 %) and found to be significantly associated with multifocal or diffuse involvement (p = 0.001), Borrmann type 4 (p = 0.005), advanced pathologic T (p < 0.001), N (p < 0.001), overall stage (p < 0.001), and total gastrectomy (p < 0.001). In multivariate analyses, which included prognostic factors of localized gastric cancer, macroscopic serosal changes were significantly associated with poor RFS [hazard ratio (HR) 2.0; 95 % confidence interval (CI), 1.4-2.7; p < 0.001] and OS (HR 2.1; 95 % CI 1.5-3.0; p < 0.001). The changes also were significantly related to shorter time to peritoneal recurrence (HR 2.9; 95 % CI 1.7-5.0; p < 0.001). CONCLUSIONS Intraoperatively assessed macroscopic serosal changes confer a poor prognosis and increased peritoneal recurrence for patients with curatively resected gastric cancer. Macroscopic assessment of serosal changes may be a useful indicator that allows better risk stratification of patients with resected gastric cancer in terms of prognosis and peritoneal recurrence.

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
BACKGROUND Survival estimates following surgical resection of gastric adenocarcinoma are traditionally reported as survival from the date of surgery. Conditional survival (CS) estimates, however, may be more clinically relevant by accounting for time already survived. We assessed CS following surgical resection for gastric adenocarcinoma. METHODS We analyzed 807 patients who underwent resection for gastric adenocarcinoma from 2000 to 2012 at seven participating institutions in the U.S. Gastric Cancer Collaborative. Cox proportional hazards models were used to evaluate factors associated with overall survival. Three-year CS estimates at "x" year after surgery were calculated as follows: CS3 = S(x+3)/S(x). RESULTS Overall 1-, 3-, and 5-year overall survival rates after gastric resection were 42, 34, and 30 %, respectively. Using CS estimates, the probability of surviving an additional 3 years given that the patient had survived at 1, 3, and 5 years were 56, 71, and 82 %, respectively. Patients with higher risk at baseline (i.e., stage III or IV disease, lymphovascular invasion) demonstrated the greatest increase in CS over time. CONCLUSIONS Survival estimates following surgical resection of gastric adenocarcinoma is dynamic; the probability of survival increases with time already survived. Patients with worse prognostic features at the time of surgery had the greatest increases in CS over time. Conditional survival estimates provide important information about the changing probability of survival over time and should be used among patients with resected gastric adenocarcinoma to guide subsequent follow-up strategies.

Abstract
PURPOSE Peritoneal recurrence is one of the most common patterns of recurrence after gastric cancer surgery and it has a poor prognosis despite all efforts. The aim of this study is to evaluate the prognostic impact of early postoperative intraperitoneal chemotherapy (EPIC) after surgery with curative intent for macroscopically serosa-invading gastric cancer patients. MATERIALS AND METHODS The records of 245 patients under the age of 70 were reviewed. These patients were suffering from macroscopically seroa-invading gastric cancer and they underwent curative surgery from 1995 to 2004 at the Kyungpook National University Hospital, Daegu, Korea. The overall survival, gastric cancer-specific survival, complications, and patterns of recurrence were compared between the patients who were treated with EPIC and those who were not. RESULTS EPIC was administered to 65 patients, and the remaining 180 patients did not receive this treatment. The 5-year overall and gastric cancer-specific survival rates for the EPIC group were 47.4% and 53.1%, respectively, and those for the non-EPIC group were 26.7% and 29.7%, respectively (p=0.012 for overall survival and p=0.011 for gastric cancer-specific survival). The rates of peritoneal recurrence for the EPIC group and the non-EPIC group were 18.5% and 32.2%, respectively (p=0.038). There were no significant differences in the morbidity or mortality between the two groups. Based on a multivariate analysis of the factors with prognostic significance in univariate analyses, EPIC, pathological lymph node metastasis, differentiation, and the extent of gastric resection were independent prognostic factors. CONCLUSION The use of EPIC to treat gastric cancer patients with macroscopic serosal invasions resulted in better survival rate by reducing the risk of peritoneal recurrence.

Abstract
BACKGROUND Reports on recurrence and outcomes of US patients with gastric cancer are scarce. The aim of this study was to determine incidence and pattern of recurrence after curative intent surgery for gastric cancer. STUDY DESIGN Using the multi-institutional US Gastric Cancer Collaborative database, we identified 817 patients undergoing curative intent resection for gastric cancer between 2000 and 2012. Patterns and rates of recurrence along with associated risk factors were identified using adjusted regression analysis. Recurrences were classified as locoregional, peritoneal, or hematogenous. RESULTS Median patient age was 65.8 years (interquartile range [IQR] 56.4, 74.7); the majority of patients were male (n = 462, 56.6%) and white (n = 511, 62.5%). At the time of surgery, the majority of patients underwent a partial gastrectomy (n = 481, 59.2%) with a complete R0 resection achieved in 91.6% (n = 748) of patients. At the time of last follow-up, 244 (29.9%) of 817 patients developed a recurrence; 163 (66.8%) patients had recurrence at only a single site; the remaining 81 (33.2%) had multiple sites of initial recurrence. Among patients who recurred at a single site, recurrence was most common at a distant location and included hematogenous (n = 57, 23.4%) or peritoneal (n = 47, 19.3%) only metastasis. Tumors at the gastroesophageal junction (odds ratio [OR] 3.18, 95% CI 1.08 to 9.40; p = 0.04) were associated with higher risk of locoregional recurrence, while the presence of multiple lesions (OR 10.82, 95% CI 3.56 to 32.85; p < 0.001) remained associated with an increased risk of distant hematogenous recurrence after adjusted analysis. Recurrence was associated with worse survival, with a median recurrence-free survival of 10.8 months (IQR 8.9, 12.8) among those who experienced a recurrence. CONCLUSIONS Nearly one-third of patients experienced recurrence after gastric cancer surgery. The most common site of recurrence was distant.

Abstract
BACKGROUND Use of perioperative chemotherapy (CTx) alone versus chemoradiation therapy (cXRT) in the treatment of resectable gastric cancer remains varied. We sought to define the utilization and effect of CTx alone versus cXRT on patients having undergone curative-intent resection for gastric cancer. METHODS Using the multi-institutional US Gastric Cancer Collaborative database, we identified 505 gastric cancer patients between 2000 and 2012 who received perioperative therapy in addition to curative-intent resection. The impact of perioperative therapy on survival was analyzed by the use of propensity-score matching of clinicopathologic factors among patients who received CTx alone versus cXRT. RESULTS Median patient age was 62 years, and most patients were male (58.2 %). Most patients had a T3 (38.7 %) or T4 (36.8 %) lesion and lymph node metastasis (73.4 %). A total of 211 (42.8 %) patients received perioperative CTx alone, whereas the remaining 294 (58.2 %) patients received cXRT. Factors associated with receipt of cXRT were younger age (odds ratio, 1.93) and lymph node metastasis (odds ratio, 4.02; both P < 0.05). At a median follow-up of 28 months, the median overall survival (OS) was 33.4 months, and the 5-year OS was 36.7 %. Factors associated with worse overall survival included large tumor size [hazard ratio (HR), 1.83], T3 (HR 2.96) or T4 (HR 4.02) tumors, and lymph node metastasis (HR 1.57; all P < 0.05). In contrast, receipt of cXRT was associated with improved long-term OS (CTx alone, 20.9 months; cXRT, 46.7 months; HR 0.51; P < 0.001). CONCLUSIONS cXRT was utilized in 58 % of patients undergoing curative-intent resection for gastric cancer. With propensity score-matched analysis, cXRT was an independent factor associated with improved recurrence-free survival and OS.

Abstract
PURPOSE To improve the efficacy of adjuvant chemotherapy with mitomycin-C and fluoropyrimidine (Mf) in gastric cancer, we designed a new regimen (iceMFP) and investigated in a phase III study. METHODS We randomly assigned 640 patients with resectable and macroscopically recognizable serosa-invading gastric cancer to Mf or iceMFP group during operation. The Mf consisted of intravenous mitomycin-C (20 mg/m(2)) at 3-6 weeks after surgery and oral doxifluridine (460-600 mg/m(2)/day) starting 4 weeks after the administration of mitomycin-C and continuing for 3 months. The iceMFP consisted of intraoperative intraperitoneal cisplatin (100 mg), intravenous mitomycin-C (15 mg/m(2)) on postoperative day 1, followed by oral doxifluridine for 12 months, and six monthly intravenous cisplatin (60 mg/m(2)). The primary endpoint was 3-year recurrence-free survival (RFS). RESULTS A total of 521 patients (258 in Mf, 263 in iceMFP) were eligible for analysis after excluding patients with stage I disease, distant metastasis, or R1 resection. With a median follow-up of 3.5 years, the iceMFP group had a higher RFS (hazard ratio [HR] 0.70; 95 % confidence interval [CI] 0.54-0.90; p = 0.006; 3-year RFS 60 % vs. 50 %) and overall survival (HR 0.71; 95 % CI 0.53-0.95; p = 0.02; 3-year overall survival, 71 vs. 60 %) compared with the Mf group. This was confirmed at extension analysis after a median 6.6 years of follow-up. Both regimens were well tolerated with no differences in surgical complications. CONCLUSION The efficacy of adjuvant Mf was significantly improved by the additional therapeutic strategies of iceMFP. Considering negative results of AMC0201, these suggest that early initiation of chemotherapy and/or intraperitoneal cisplatin played a distinct role in the improved efficacy.

Abstract
PURPOSE To explore the time and pattern of recurrence of proximal gastric cancer and estimate the risk factors and prognostic factors for it. Considering these risk factors, postoperative adjuvant therapies and follow-up program can be individualized. METHODS The data of 135 recurrence proximal gastric cancer patients were extracted and analyzed. RESULTS In 135 recurrence patients, the median time to recurrence was 14.0 months, 116 (85.9%) patients had recurrences within 2 years. Loco-regional recurrence was the most prevalent pattern. Hematogenous metastasis was next prevalent pattern in which the liver was the most common organ. Peritoneal recurrence occurred in 32 patients. Five patients recurred in distant lymph nodes. The deeper invasion was associated with higher incidence of hematogenous metastases and peritoneal recurrence. The histological type, depth of invasion, and lymph node metastasis were independent risk factors for overall recurrence. While, negative lymph nodes counts were another independent risk factors for early recurrence. Patients with systemic recurrence and early recurrence patients had poorer prognosis. CONCLUSION Total gastrectomy and adequate lymph nodes dissection were rational choice of proximal gastric cancer with deeper invasion. Pathologic predictors of invasion, histological type, lymph nodes metastasis and negative lymph node counts could guide individualized, risk-oriented adjuvant treatment, and follow-up plan.

Abstract
Purpose The aim of the present study was to assess the association between the pre-operative plasma fibrinogen level and the adjacent organ involvement in advanced gastric cancer. Materials and Methods A total of 923 pre-operative plasma samples were obtained from 923 patients diagnosed clinically as having advanced gastric cancer, and fibrinogen levels were measured by immunoassay. Associations between fibrinogen levels and clinicopathologic findings (depth of tumor, adjacent organ involvement, and lymph node metastasis), along with survival were examined by univariate and multivariate analyses. Results Tumor size, tumor depth, and the presence of lymph node metastasis were found to be positively correlated with the preoperative plasma fibrinogen levels (P<0.001). Fifty (5.4%) patients had adjacent organ involvement. Lymphatic invasion (P<0.001), tumor size (P<0.001), clinical T (depth of invasion) stage (P<0.001), and clinical nodal stage (P=0.018) were found to be associated with adjacent organ involvement. Univariate and multivariate regression analyses showed that a preoperatively elevated plasma fibrinogen level was associated with adjacent organ involvement (P<0.001, 0.028), and Kaplan-Meier analysis showed that it was associated with poorer survival (P<0.001). Conclusions Plasma fibrinogen was found to be a clinically useful marker of adjacent organ involvement and overall survival. When a high fibrinogen level is encountered, preoperatively, adjacent organ involvement should be suspected in clinically advanced gastric cancer.

Abstract
BACKGROUND The purpose of this study was to compare the clinical usefulness of the seventh Union Internationale Contre le Cancer/American Joint Committee on Cancer (AJCC/UICC) staging system vs the sixth AJCC/UICC staging system in patients with gastric cancer. STUDY DESIGN Included were 1,799 patients who underwent surgery for gastric cancer between January 2001 and June 2005 at the National Cancer Center (South Korea). For the sixth and seventh AJCC/UICC staging systems, survival outcomes stratified by stage, by T classification, and by N classification were summarized using Kaplan-Meier curves and compared statistically using a log rank test; survival differences were quantified using hazard ratios estimated from a Cox regression model. The 2 systems were compared in terms of prognostic performances using the linear trend chi-square test, likelihood ratio chi-square test, and Akaike information criterion (AIC) in the Cox regression analysis. RESULTS Significant survival differences between each stage were not found using the seventh staging system, especially for stages IB, IIA, and IIB (p = 0.14 and p = 0.11). The sixth staging system had higher linear trend chi-square score and likelihood ratio chi-square score, which means better discriminatory ability, monotonicity, and homogeneity, and had smaller AIC, which indicates better optimistic prognostic stratification, especially in the N classification. The modified staging system combining the T classification of the seventh AJCC/UICC system and the N classification of the sixth system showed better prognostic performance compared with each separate version (sixth or seventh) of the staging system. CONCLUSIONS The seventh AJCC/UICC staging system is not more clinically useful than the sixth system in surgically treated patients with gastric cancer because of an inappropriate N classification. A new TNM system is required with a different N classification.

Abstract
BACKGROUND/AIMS The prognostic value of cytological examination of intraoperative washings in potentially resectable gastric cancer is controversial. METHODOLOGY Between February 1993 and August 2001, clinicopathological features and surgical outcome of 26 consecutive patients with gastric cancer with positive cytological findings of peritoneal washings without peritoneal dissemination were retrospectively analyzed. RESULTS The overall 1, 2, 3-year survival rates for 26 patients were 69%, 35%, and 0%, respectively. The median survival was 17.5 months. The median survival of patients with curative resection (n=16) and non-curative resection (n=10) was 19 months and 12.5 months, respectively. There was no significant difference in survival between curative resection and non-curative resection (p=0.10). Recurrent disease frequently occurred as peritoneal dissemination (69%). No patient survived for more than 34 months. CONCLUSIONS Aggressive surgical resections do not provide any survival benefit for gastric cancer with positive cytological findings of peritoneal washings even in the absence of peritoneal dissemination.
