Biomed Pharmacother 2020; 126:110104. [PMID: 32224371 DOI: 10.1016/j.biopha.2020.110104] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2019] [Revised: 02/23/2020] [Accepted: 03/11/2020] [Indexed: 12/12/2022] Open
Abstract
dl-Mandelic acid (MA), an alpha-hydroxycarboxylic acid, has been widely used as an intermediate of pharmaceutical and fine chemicals. Here, we evaluated the sperm-immobilizing activity of MA and its safety profiles. Spermatozoon motility was assessed by computer-aided sperm analysis, the integrity of the plasma membrane and. mitochondrial potential was assessed using fluorescein isothiocyanate-pisum sativum agglutinin and JC-1, respectively. The local tolerance of the MA-containing gel formulation was evaluated using a rabbit vaginal irritation test. We found that MA inhibited sperm motility and movement patterns in a concentration-dependent manner. Within 20 s, MA-induced spermatozoa immobilization occurred with a minimum effective concentration and a median effective concentration of 0.86 and 0.54 mg/mL, respectively. Plasma membrane disruptions of MA-treated spermatozoa were relatively mild, but mitochondrial depolarization occurred. Histopathological examination showed that MA exposure did not exert obvious effects on the integrity of spermatozoa membrane structures and only caused slight irritation to the rabbit vaginal epithelium. The vaginal irritation scores of the vehicle control and the nonoxynol -9 gel control groups were 1.38 ± 0.65 and 7.88 ± 1.67, respectively (p < 0.01), whereas those of the MA gel groups at 10, 20, and 40 mg/mL were 1.69 ± 1.04, 2.98 ± 0.77, and 4.35 ± 1.04 with p values of >0.05, >0.05, and <0.05 (vs. vehicle control), respectively, which were within the clinically acceptable range (<8). Therefore, our results confirmed that MA exhibited significant sperm-immobilizing effects and caused mild plasma membrane injury, suggesting that it has potential for development as a future non-surfactant spermicide.

Abstract
Aims and background Gastric cancer is associated with high mortality. Although the liver is a common site of metastases in this tumor, the experience with liver-directed therapies is limited. Methods We report a single-center experience involving four patients with liver metastases from gastric cancer treated by hepatic arterial infusion (HAI). In addition, we performed a search for reports on HAI in gastric cancer metastatic to the liver and used the studies with data on survival of individual patients for a pooled analysis. Results Among three valuable patients, one had a complete response, one had stable disease and one had progressive disease. The patient with complete response is still alive 41 months after the diagnosis of liver metastases, while the other patients died 6, 22 and 31 months after the diagnosis. Objective responses were observed in 48% of the 25 patients in the pooled analysis. Objective response and limited hepatic involvement were independent predictors of survival in these patients. Conclusions Although isolated liver involvement in metastatic gastric cancer is rare, HAI seems to be similarly effective in these patients as in patients with liver metastases from colorectal cancer. The prognosis is significantly better in gastric cancer patients who have limited hepatic involvement and attain an objective response after HAI.

Is signet-ring cell carcinoma a specific entity among gastric cancers? Gastric Cancer 2016; 19:1027-1040. [PMID: 26606931 DOI: 10.1007/s10120-015-0564-2] [Citation(s) in RCA: 55] [Impact Index Per Article: 6.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/07/2015] [Accepted: 11/02/2015] [Indexed: 02/07/2023]
Abstract
BACKGROUND The prognosis and chemoresistance of signet-ring cell (SRC) gastric adenocarcinoma have been reported and debated, and the utility of perioperative chemotherapy for such a tumor has been questioned . This study was performed to assess the impact of the SRC type on survival following resection of gastric adenocarcinoma, and to assess whether the prognostic factors (including perioperative chemotherapy) for non-SRC adenocarcinoma differed from those for SRC adenocarcinoma. METHODS 1799 cases of adenocarcinoma that were consecutively treated from 1997 to 2010 in 19 French centers by subtotal or total gastrectomy were included in a retrospective study. A D2 lymphadenectomy was performed for antropyloric tumors, and a modified D2 for upper tumors. SRC adenocarcinoma was diagnosed based on the presence of isolated carcinoma cells containing mucin. RESULTS A total gastrectomy was performed in 979 (54.4 %) patients. SRC adenocarcinoma was diagnosed in 899 (50 %) patients. Patients with an SRC tumor were more frequently female, younger, and malnourished, had lower ASA scores, and had larger tumors than non-SRC patients. Median survival in patients with non-SRC carcinoma was 51 months, as compared to 26 months in patients with SRC carcinoma (p < 0.001). At multivariate analysis, SRC type remained an independent adverse prognostic factor (HR = 1.182). Factors that were prognostic in the SRC subgroup but not in the non-SRC subgroup were age >60 years, linitis, and involvement of adjacent organs. In contrast to non-SRC tumors, pre- and postoperative chemotherapy did not significantly impact on survival following resection of SRC adenocarcinoma. CONCLUSION In comparison to non-SRC adenocarcinoma, the SRC type has a worse prognosis, different prognostic factors, and is only poorly sensitive to perioperative chemotherapy. Non-SRC and SRC adenocarcinomas should be considered different entities in future therapeutic trials.

Abstract
BACKGROUND/AIMS We previously demonstrated the safety and efficacy of low-dose, short-interval target vessel regional chemotherapy (TVRC(LDSI)) delivered through the hepatic artery with transarterial embolization (TAE) in patients with advanced gastric cancer (AGC). The present study aimed to compare the efficacy of TAE + TVRC(LDSI) with that of standard TAE + TVRC in AGC patients with liver metastases who failed to respond to first- or second-line systemic chemotherapy. METHODS This study recruited a total of 58 GC patients with liver metastases after failure of first- or second-line systemic chemotherapy. Twenty-eight patients were assigned to the TAE + TVRC(LDSI) group and 30 patients to the TAE + TVRC group. The primary end point was overall survival (OS(TVRC)), which was defined as the time from the initiation of TVRC until the last follow-up or death. RESULTS OS(TVRC), time to progression (TTP) until appearance of intra- and extrahepatic metastases, and overall TTP and treatment periods in the TAE + TVRC(LDSI) group were all significantly longer than in the TAE + TVRC group (all p < 0.001). CONCLUSION TAE + TVRC(LDSI) had a higher efficacy and safety, which was reflected by OS rates, progression-free survival rates, longer duration of treatment and milder side effects compared to standard TAE + TVRC.

Abstract
BACKGROUND For several types of cancer, including gastric cancer (GC), tumor cells at the invasive front are considered to have a more aggressive behavior compared with those in the more central region. The aim of the present study was to analyze the expression of MMP-7, laminin γ2 and EGFR in a large number of GCs and to investigate how these expression patterns correlate with clinicopathologic parameters, infiltrative patterns, histology or mucin phenotype. METHODS We immunohistochemically examined the expression of MMP-7, laminin γ2 and EGFR using a tissue microarray analysis of 790 GCs, and evaluated their clinicopathological significance. RESULTS MMP-7, cytoplasmic laminin γ2, extracellular laminin γ2 and EGFR expression were observed in 25, 25, 8 and 21 % of the 790 GC cases, respectively. Expression of MMP-7, cytoplasmic laminin γ2 and EGFR was associated with advanced T grade, N grade and tumor stage. Extracellular laminin γ2 expression was not associated with any clinicopathologic parameters, infiltrative patterns, histology or mucin phenotype. Furthermore, we investigated the correlations of MMP-7, laminin γ2 and EGFR expression. MMP-7 expression was significantly more frequent in positive expression of cytoplasmic laminin γ2 than negative cases, and EGFR expression was significantly more frequent in positive expression of cytoplasmic laminin γ2 and MMP-7. CONCLUSIONS Molecular expression of MMP-7, laminin γ2 or EGFR, and their combinations, may be associated with GC tumor aggressiveness. Assessment of expression of these molecules at the invasive front of primary tumors is clinically significant in predicting the malignant behavior of GC.

Abstract
Background Palliative gastrectomy for patients with advanced gastric cancer remains controversial. The objective of the present meta-analysis was to analyze survival outcomes and establish a consensus on whether palliative gastrectomy is suitable for patients with incurable advanced gastric cancer and which type of patients should be selected to receive palliative gastrectomy. Methods A literature search was conducted in PubMed, EMBASE and the Cochrane Library. The results for overall survival in the meta-analysis are expressed as hazard ratios (HRs) with 95% confidence intervals (CIs). Results Of 1647 articles and abstracts reviewed, 14 studies with 3003 patients were eligible for the final analysis. The meta-analysis revealed that palliative gastrectomy is associated with a significantly improvement in overall survival (HR 0.56; 95%CI 0.39–0.80; p < 0.002) compared that of patients treated without palliative gastrectomy. An improvement in survival was also observed in patients with stage M1 gastric cancer who received palliative gastrectomy (HR 0.62; 95%CI 0.49–0.78; p < 0.0001), especially those with peritoneal dissemination (HR = 0.76, 95%CI 0.63–0.92), liver metastasis (HR = 0.41, 95%CI 0.30–0.55), or distant lymph-node metastasis (HR = 0.36, 95%CI 0.23–0.59). Combined hepatic resection may be beneficial for patients who under palliative gastrectomy (HR 0.30; 95%CI 0.15–0.61; p = 0.0008). The overall survival of patients who underwent palliative gastrectomy combined with chemotherapy was significantly improved (HR 0.63; 95%CI 0.47–0.84; p = 0.002). Conclusions From the results of the meta-analysis, palliative gastrectomy for patients with incurable advanced gastric cancer may be associated with longer survival, especially for patients with stage M1 gastric cancer. Combined hepatic resection for patients with liver metastasis and chemotherapy may be beneficial factors compared to simple palliative gastrectomy.

Abstract
Since regional drug administration enables to maintain a high drug concentration within tumors, we compared the plasma concentration and biodistribution of doxorubicin (Dox) from drug-loaded conventional liposomes by local or systemic administration. The results demonstrated that drug concentration was substantially improved in liver as well as a decrease in blood and other organs by spleen injection mimicking portal vein perfusion (regional administration). To further investigate the targeted therapeutic effect of galactosylated liposome encapsulated doxorubicin (Dox) by regional administration, liver targeting liposomes were prepared by incorporating galactosylated-DPPE to conventional liposomes. Liposome uptake and targeting were verified in vitro and in vivo by fluorescence microscopy and xenogen IVIS imaging system, respectively. The results showed that galactose targeted liposomes presented a stronger specific cell uptake by human hepatocellular carcinoma HepG2 cells compared to the non-targeted liposomes. In vivo fluorescence imaging showed that the intra-hepatic deposition of conventional and galactosylated liposomes via spleen injection was more than that via tail vein administration, and galactosylated liposomes had higher fluorescent intensity over conventional liposomes in the liver post spleen administration. The anti-tumor effect of various drug administration routes for both liposomal formulations was evaluated using a murine liver metastasis model of colon cancer. The results indicated that tumor progression in the liver and mesenteric lymph nodes was significantly suppressed by Dox-loaded galactosylated liposomes via spleen injection, while no significance was observed in non-targeted formulations. Our data indicated that local perfusion of galactosylated liposomal doxorubicin had a great promise for the treatment of liver metastasis from colon cancer.

Abstract
BACKGROUND The survival benefit of palliative gastrectomy in patients with peritoneal metastasis as a single incurable factor remains unclear. METHODS A total of 148 gastric cancer patients with peritoneal metastasis underwent gastrectomy or chemotherapy at the Shizuoka Cancer Center between September 2002 and December 2008 and were included in this study. The effects of gastrectomy and chemotherapy on their long-term outcome were investigated. Multivariate analysis was also performed to identify independent prognostic factors. RESULTS Gastrectomy was performed in 82 patients and subsequent chemotherapy was administered to 55. Chemotherapy was selected as an initial treatment for 66 patients. Median survival time (MST) was identical between patients with and without gastrectomy (13.1 vs. 12.0 months; P = 0.410). Conversely, MST was significantly longer in patients who received chemotherapy (13.7 months) than those who did not (7.1 months; P = 0.048). According to the results of multivariate analysis, chemotherapy (hazards ratio [HR] = 0.476; 95 % CI = 0.288-0.787) was selected as an independent prognostic factor, while gastrectomy was not. CONCLUSIONS The results of the present study did not show a survival benefit of palliative gastrectomy in selected patients with peritoneal metastasis. Instead, chemotherapy has to be considered as an initial treatment for these patients.

Abstract
PURPOSE In the United States, gastric cancer is rapidly fatal with a 25% 5-year survival. Of the few patients who survive, little is known about their demographic, clinical, and tumor characteristics. PATIENTS AND METHODS Data regarding all cases of gastric and gastroesophageal junction (GEJ) adenocarcinoma diagnosed in California between 1988 and 2005 were obtained from the California Cancer Registry, a member of the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program. A Cox proportional hazards model was constructed to understand the independent relationships of patient demographic, disease, and treatment factors with survival. RESULTS We identified 47,647 patients diagnosed with gastric or GEJ cancer. Of those, only 9,325 (20%) survived at least 3 years. Variables associated with longer survival were localized stage (hazard ratio [HR], 0.20), surgery with diagnosis in 2002 or later (HR, 0.34), surgery with diagnosis in 2001 or before (0.37), regional stage (HR, 0.53), chemotherapy (HR, 0.56), intestinal histology (HR, 0.74), well- or moderately differentiated tumors (HR, 0.76), radiation (HR, 0.80), Asian/Pacific Islander race (HR, 0.81), treatment at an academic hospital (HR, 0.85), fundus/body/antrum location (HR, 0.90), highest socioeconomic status quintile (HR, 0.91), female sex (HR, 0.92), Hispanic race (HR, 0.92), and hospital size more than 150 beds (HR, 0.94). Kaplan-Meier curves showed longer median disease-specific survival (DSS) in patients with tumors originating in the fundus/body/antrum compared with esophagus/cardia (13.4 v 10.8 months). Intestinal histology had significantly longer median DSS (28.9 months) compared with other (11.0 months) or diffuse (10.1 months) histology. CONCLUSION Patients who survive gastric and GEJ cancer more than 3 years after diagnosis have demographic and pathologic characteristics distinct from those who do not survive.

Abstract
BACKGROUND Tannins extracted from immature fruits of Terminalia chebula Fructus Retz. are considered as effective components promoting the process of wound healing. The objective of this study is to explore the optimal extraction and purification technology (OEPT) of tannins, while studying the use of this drug in the treatment of a cutaneous wound of rat as well as its antibacterial effects. METHODS The content of tannin extracts was measured by the casein method, and antibacterial ability was studied by the micro-dilution method in vitro. In wound healing experiment, animals in group Ⅰ, Ⅱ and Ⅲ were treated with vaseline ointment, tannin extracts (tannin content: 81%) and erythromycin ointment, respectively (5 mg of ointment were applied on each wound). To evaluate the process of wound healing, selected pharmacological and biochemical parameters were applied. RESULTS After optimal extraction and purification, content of tannin extracts was increased to 81%. Tannin extracts showed the inhibition of Staphylococcus aureus and Klebsiella Pneumonia in vitro. After excision of wounds, on days 7 and 10, the percent of wound contraction of group Ⅱ was higher than that of group Ⅰ. After being hurt with wounds, on days 3, 7, and 10, the wound healing quality of group Ⅱ was found to be better than that of group Ⅰ in terms of granulation formation and collagen organization. After wound creation, on day 3, the vascular endothelial growth factor expression of group Ⅱ was higher than that of group Ⅰ. CONCLUSION The results suggest that tannin extracts from dried immature fruits of Terminalia chebula Fructus Retz. can promote cutaneous wound healing in rats, probably resulting from a powerful anti-bacterial and angiogenic activity of the extracts.

Abstract
BACKGROUND This pilot study was carried out to evaluate the efficacy of chemotherapy for patients with peritoneal dissemination from gastric cancer or positive lavage cytology diagnosed by staging laparoscopy. METHODS Sixteen patients were enrolled. Paclitaxel was administered at 120 mg/m(2) on day 1 and S-1 was administered orally at 80 mg/m(2) for 14 consecutive days, followed by a 1-week rest, as one course. After five courses of this therapy, the primary gastric tumors were evaluated and second-look laparoscopy was performed for patients showing partial response or stable disease with clinical benefit. RESULTS Partial response or stable disease with clinical benefit was confirmed in seven and five patients, respectively, and these patients underwent second-look laparoscopy. No viable cancer cells were detected on cytopathological investigation during second-look laparoscopy in 9 patients who underwent surgical treatment. The intent-to-treat response rate for gastric tumor was 44% and the rate of disappearance of peritoneal metastasis was 38% (6 cases) at surgery. The median survival time was 555 days. Leucopenia of grade 3 and neutropenia of grade 3 were recognized in two and three patients, respectively. CONCLUSION This chemotherapy regimen may be an acceptable option for patients with peritoneal dissemination. We plan to study this regimen further in gastric cancer patients with peritoneal dissemination.

Abstract
BACKGROUND Although the prognosis of stage IV gastric cancer is poor, some patients with stage IV gastric cancer had a long-term survival after gastrectomy. The objective of this study was to subclassify stage IV gastric cancer according to survival differences, evaluate the prognosis by substage, and identify the factors associated with patient survival in each substage. METHODS The data from 1,176 patients who underwent gastric resection for stage IV gastric cancer between 1988 and 2007 at Tumor Hospital of Harbin Medical University were reviewed retrospectively. The patients were divided into three substages according to the survival differences: stage IVa (T1-2N3M0), stage IVb (T3N3M0 and T4N1-2M0), and stage IVc (T4N3M0 and TanyNanyM1). The clinicopathological characteristics as well as survival of the patients were evaluated retrospectively by substage. RESULTS There were no significant differences in survival among T3N3M0, T4N1M0, and T4N2M0 groups (p = 0.884) and between T4N3M0 and TanyNanyM1 groups (p = 0.192). The 5-year survival rates in stage IVa (T1-2N3M0), stage IVb (T3N3M0 and T4N1-2M0), and stage IVc (T4N3M0 and TanyNanyM1) were 22.7%, 9.9%, and 2.2%, respectively (p < 0.001). Multivariate analysis showed the following independent prognostic factors for survival: subclassification, operation type, number of retrieved lymph nodes, curability, and chemotherapy for stage IV gastric cancer; curability, chemotherapy, and number of retrieved lymph nodes for stage IVa and IVb; chemotherapy and operation type for stage IVc. For 406 patients with curative resection in stage IVa and IVb, hematogenous recurrence (35.9%) was the dominant recurrence pattern in stage IVa, whereas the most common patterns of recurrence were peritoneal (40.8%) and locoregional recurrence (31.8%) in stage IVb. CONCLUSIONS Subclassification of stage IV gastric cancer into IVa (T1-2N3M0), IVb (T3N3M0 and T4N1-2M0), and IVc (T4N3M0, TanyNanyM1) may be helpful to predict the outcome and determine the therapeutic strategies for patients with stage IV gastric cancer.

Abstract
This pilot study was undertaken to assess the effect of weekly docetaxel, cisplatin and fluorouracil (DCF) as a preoperative treatment for gastric cancer with multiple synchronous hepatic metastases. Gastric cancer patients with synchronous multiple liver metastasis were first given preoperative chemotherapy consisting of two courses (each course consisted of 6-week administration and 2-week withdrawal) of weekly DCF regimen. Following the operation, postoperative chemotherapy and hepatic arterial infusion (HAI) treatment were performed as required. Eight patients completed two courses of preoperative chemotherapy with weekly DCF regimen. No toxicity of grade 3 or more was observed during the course of chemotherapy. The response rate was 100% according to the RECIST criteria. Seven of the patients have survived for over 1 year, and six of them are still alive after more than 1 year. Because of the unexpected high response to weekly DCF, we consider that it should be verified through phase II and III trials as an important part of the comprehensive treatment for gastric cancer with liver metastasis.

Abstract
BACKGROUND AND AIMS Cancer invasion and metastasis are critical events for patient prognosis; however, the most important step in the whole process of lymph node (LN) metastasis in gastric cancer remains obscure. In this study, the significance of cancer cell behaviors, such as cell detachment, stromal invasion and lymphatic invasion on regional LN metastasis in gastric cancer was investigated by comprehensive immunohistochemistry. METHODS A total of 210 cases with gastric cancer were selected. These consisted of 105 cases with regional LN metastasis (LN[+] group) and 105 cases without LN metastasis (LN[-] group). Both groups exhibited the same depth of invasion. Cancer tissues were subjected to immunohistochemistry with antibodies against claudin-3, claudin-4, beta-catenin, matrix metalloproteinase (MMP)-1, and MMP-2, as well as endothelial markers of lymphatic vessel endothelial hyaluronan receptor-1 and von Willebrand factor for the objective discrimination between lymphatics and blood vessels. The expression of each protein as well as the histopathological parameters were compared between LN(+) and LN(-) groups. RESULTS Along with lymphatic invasion by cancer cells and gross tumor size, MMP-1 expression in cancer cells at the invasive front of the primary tumor was a significant, independent predictor of LN metastasis. The expression of claudins and beta-catenin was associated with the histopathological type of cancer, but not with LN status. CONCLUSION Among the cancer invasion-related proteins examined, MMP-1 plays a vital role in LN metastasis of gastric cancer. Tumor size, lymphatic invasion and MMP-1 expression level at the invasive front were the predictive factors of LN metastasis of gastric cancer.

Abstract
BACKGROUND AND OBJECTIVES The prognosis for patients with stage IV gastric cancer is still very poor. The purpose of this study was to evaluate the surgical outcome and prognosis, and to determine the prognostic influence of sub-stages of stage IV gastric cancer. METHODS From 1992 to 2002, 287 patients histologically diagnosed with stage IV gastric cancer underwent gastrectomy at the Department of Surgery, Ruijin Hospital, China. Regarding TNM categories, we separated them into T1-3N3M0, T4N1-2M0, T4N3M0, and TanyNanyM1 groups. We compared the clinicopathological characteristics as well as the survival in these groups. RESULTS There were largest proportions of patients who underwent extended lymphadenectomy and curative gastrectomy in T1-3N3M0 group followed by T4N1-2M0, T4N3M0, and TanyNanyM1 groups. The survival rate of patients with sub-stage IVa (T1-3N3M0 and T4N1-2M0) tumors was significant higher than that of patients with sub-stage IVb (T4N3M0 and TanyNanyM1) tumors (P = 0.008). Multivariate analysis showed that sub-stage with the highest risk ratio (1.454), and the surgical curability were independent prognostic factors in patients with stage IV gastric cancer. CONCLUSIONS Sub-stages IVa (T1-3N3M0 and T4N1-2M0) and IVb (T4N3M0 and TanyNanyM1) may predict patients' prognosis more accurately. Curative resection should be performed whenever possible in patients with stage IV gastric cancer.

Abstract
BACKGROUND There is no standard treatment for peritoneal dissemination from gastric cancer. A novel combination chemotherapy has been introduced for patients with advanced gastric cancer with peritoneal metastasis. METHODS This pilot study was performed on four patients to confirm safety and efficacy. They were diagnosed with unresectable gastric cancer with severe peritoneal dissemination by staging laparoscopy, or with metastasis to the transverse colon. We selected combined chemotherapy with both paclitaxel and S-1. Paclitaxel at 60 mg/m(2) or 60 mg/body was administered intraperitoneally on days 1 and 8 and S-1, at 80-120 mg/body, was administered orally for 14 days followed by 7 days' rest, as one course. After five courses of this therapy, the primary gastric tumors were evaluated by conventional examinations, and second-look laparoscopy was performed to assess the efficacy of the treatment against the peritoneal metastases. RESULTS After five courses, primary tumor reductions were confirmed, and no cancer cells were detected on pathocytological investigation during second-look laparoscopy in any of the patients. Three patients underwent total gastrectomy with lymph node dissection and one underwent left upper abdominal evisceration. Final histological staging showed two stage 3 and two stage 4 patients. The intraperitoneal administration of paclitaxel and the oral administration of S-1 were well tolerated. Three patients died, at 8, 15, and 29 months, respectively, after the initial treatment, and one has been alive for 54 months without recurrence. CONCLUSION This chemotherapy can be used in the treatment of patients with peritoneal metastasis of gastric cancer.

Abstract
PURPOSE To investigate the value of palliative gastrectomy and chemotherapy in a large series of patients with stage IV gastric cancer. METHODS A total of 389 patients were identified in survival analysis. Among which, 183 cases received palliative gastrectomy (PG) and 206 cases received unresectable operation, 184 cases received palliative chemotherapy (PC) and 205 cases did not receive chemotherapy. The survival advantages of patients, based on treatments modality, were also analyzed in patients with liver metastasis, peritoneal dissemination and lymph node metastasis. RESULTS The 1-year, 3-year, 5-year survival rate of those patients who were treated with PG + PC were 85.7% (96/112), 32.1% (36/112), and 8.9% (10/112), which were far better than those who were not. For those patients with liver metastasis, peritoneal dissemination, and/or N3 lymph node metastasis, survival advantages were also present if treated with this multimodality approach. CONCLUSION The survival time and palliative duration were significantly longer in patients after PG than after non-resection operations. Postoperative chemotherapy prolonged the survival time of patients after palliative surgery. PG combined with adjuvant chemotherapy may improve survival in patients with stage IV gastric cancer, even with liver metastasis, peritoneal dissemination, and lymph node metastasis.

Abstract
Background The efficacy of operative resection of liver metastasis from colorectal cancer has been established. However, a treatment for liver metastasis from gastric cancer has not yet been established. In this study, we evaluated the efficacy of hepatic arterial infusion for synchronous hepatic metastasis from gastric cancer. Patients and methods This study consisted of 37 patients [HAI group; 18 and non-HAI group; 19] with synchronous multiple liver metastases from gastric cancer at Gunma Prefecture Saiseikai-Maebashi Hospital. We retrospectively analyzed the efficacy of HAI. Results Response rate (CR + PR) of HAI was 83%. However, HAI treatment did not affect any improvement in the survival rate. Conclusion HAI is an effective treatment for control of liver metastasis specifically. The factor effective for an improvement in the survival rate was possibly that of gastrectomy.

Abstract
BACKGROUND We retrospectively analyzed the influence of various clinicopathologic factors on the survival of patients treated with chemotherapy. METHODS A retrospective analysis was made of 110 patients with stage IV gastric cancer who were treated from January 1996 to June 2004. RESULTS Median survival time was 429 days for patients treated with S-1 therapy and 236 days for patients without S-1 therapy. A better survival was demonstrated in patients who had good performance status, one metastatic site, or had been given a second-line chemotherapy (P < 0.01). But very few patients (17%; 5/29) with multiple metastatic sites were able to receive the second-line chemotherapy. CONCLUSION Patients treated with S-1 therapy had a better prognosis than patients without S-1. One metastatic site and being given second-line chemotherapy were other factors for better prognosis. For patients with only one metastatic site, a good prognosis can be obtained by second-line chemotherapy for those refractory to S-1. The prognosis of patients who had more than two metastatic sites remained poor; more effective chemotherapy might improve the survival of such patients if they retain good performance status.

Abstract
BACKGROUND Patients with stage IV gastric cancer usually have a poor prognosis, but some patients with resectable cancer survive for more than 5 years. We aimed to study the correlation of protein expression and survival in resectable stage IV gastric cancer. PATIENTS AND METHODS Tissue samples of 42 patients with resectable stage IV gastric cancer were stained immunohistochemically for the mutant p53 protein and heat shock protein-27 (hsp27). The correlation between protein expression and clinicopathological factors was investigated. Furthermore, prognostic value of each factor was analyzed. RESULTS Univariate analysis showed that pN factors (Japanese classification, P = .028; International Union Against Cancer classification, P = .024), blood vessel invasion (P = .043), hsp27 overexpression (P = .019), and the index of p53 and hsp27 overexpression (P = .0026) had a prognostic influence. Only Lauren classification, however, revealed the prognostic influence in multivariate analysis (P = .046). CONCLUSIONS These results suggest that immunostaining of tumor specimens for p53 and hsp27 and clinicopathological analysis may help predict the survival of patients with resectable stage IV gastric cancer.

Abstract
OBJECTIVE To study the proliferative activity of AgNORs (argyropholic nucleolar organizer region) in gastric cancer tissue and in the adjacent normal tissue and correlate with the clinical and pathological parameters. MATERIAL AND METHODS Thirty four formalin-fixed paraffin-embedded tissues sections of patients with adenocarcinoma of the stomach were analysed retrospectively, being 23 of intestinal and 11 of diffuse type of Lauren. The AgNORs can be detected by a specific silver staining and the number de AgNORs was counted in 100 nucleus of tumoral cells and in 100 nucleus of the adjacent normal tissue. RESULTS The tumoral cells had numerous, smaller, aggregated or one solitary and bigger AgNORs in the nuclei, while the normal cells had one or two AgNORs by nuclei. A significant difference was found between the mean numbers of AgNORs in the nuclei of tumor (3.86) and the normal tissue (1.25). There was also a significant difference between intestinal (4.43) and diffuse type (2.58) means. No significant correlation was found between mean AgNOR count and sex or age of the patients. CONCLUSIONS The quantification of AgNORs can be used as a marker of proliferative activity, helping on the diagnosis of cancer.

Abstract
BACKGROUND p27(Kip1) is a cyclin-dependent kinase inhibitor whose loss is associated with disease progression and an unfavorable outcome in several malignancies. The authors studied its expression in a consecutive series of resected gastric carcinomas. METHODS Expression of p27(Kip1) in 71 advanced gastric carcinomas and 10 lymph nodes containing metastases was determined using an avidin-biotin-peroxidase immunohistochemical method. The relations between p27(Kip1) expression and pathologic features, patient characteristics, and survival were analyzed. RESULTS p27(Kip1) levels in gastric carcinomas ranged from 0.63-82.97% (median, 23. 10%; mean, 27.99%). There was no association found between p27(Kip1) expression and patient gender (P = 0.21), patient age (P = 0.13), tumor stage (P = 0.17), tumor grade (P = 0.22), or histologic type (P = 0.72). Univariate analysis showed that long term survival was related to stage (P < 0.0001) and grade (P = 0.03). However, tumors with p27(Kip1) levels above and below the median value were associated with a similar outcome, regardless of whether all cases (P = 0.19) or those without metastatic disease (P = 0.50) or those with residual or metastatic disease (P = 0.92) were included. When entered into a multivariate analysis, stage (P < 0.0001) and grade (P = 0.05), but not p27(Kip1) levels (P = 0.16), were found to be related to patient outcome. In lymph node metastases, p27(Kip1) expression (median, 16.5%) was similar to that found in the corresponding primary lesion (median, 30.9%). CONCLUSIONS p27(Kip1) may play a role in the pathogenesis and progression of gastric carcinoma, but its expression is unlikely to be useful as a prognostic indicator, at least in European patients with advanced disease.

Abstract
The stomach and duodenum are organs of complex physiology and cell biology. Neoplastic disease of these organs represents a difficult surgical challenge, and gastric and duodenal cancer mortality rates remain high despite advances in surgical technique, perioperative care, and adjuvant therapy. True "cures" elude the surgeon all too often. Fortunately, our understanding of the genetics and molecular biology of upper gastrointestinal neoplasms is increasing and is now significantly affecting the clinical management of these tumors as surgical therapies continue to improve. The care of benign disease of the stomach and duodenum is also evolving as medical therapy and surgical technology improve to lessen the morbidity associated with peptic ulcer disease and other benign conditions. The event that may have the greatest effect on surgical intervention in peptic ulcer disease is the Centers for Disease Control and Prevention launching of an educational campaign to promote treatment of Helicobacter pylori. This article reviews the most significant advances published in the past year on surgical intervention of the stomach and duodenum.

Abstract
BACKGROUND Recently many studies have demonstrated that the degree of tumor angiogenesis is related to the aggressiveness of the tumor and clinical outcome. Vascular endothelial growth factor (VEGF) is a well characterized inducer of angiogenesis. In this study, the authors investigated the prognostic significance of VEGF expression in patients with early gastric carcinoma together with p53 gene abnormality and tumor cell proliferation. METHODS One hundred ninety-five endoscopically biopsied specimens obtained preoperatively from patients with early gastric carcinoma were studied immunohistochemically. RESULTS According to conventional clinicopathologic factors, submucosal invasion, lymph node metastases, and tumor size were associated significantly with the incidence of disease recurrence. According to conventional biologic factors, VEGF expression was observed more frequently in patients with disease recurrence compared with those without disease recurrence whereas neither p53 abnormality nor tumor cell proliferation were correlated with prognosis. Moreover, multivariate analysis indicated that VEGF expression (as well as submucosal invasion and lymph node metastases) is an independent predictor of disease recurrence. CONCLUSIONS The results of the current study show that VEGF expression may be a useful prognostic factor for patients with early gastric carcinoma.

Abstract
Several epidemiological studies have suggested an inverse association between the risk of prostate cancer and intake of soybeans and their products. In vitro data pointing to possible anti-carcinogenic properties of the soybean isoflavone, genistein, led us to investigate the chemopreventive potential of soybean isoflavones in a rat carcinogenesis model induced by 3,2'-dimethyl-4-aminobiphenyl (DMAB) and testosterone propionate (TP). Animals received DMAB s.c. injections at 2-week intervals for the first 20 weeks and implanted silicon tubes containing 40 mg of TP, replaced at 6-week intervals throughout the experiment. The soybean isoflavone mixture consisting of 74% genistein and 21% daidzein was mixed in basal diet (AIN-76A) at concentrations of 100 and 400 ppm and fed to F344 male rats throughout the experiment. Rats treated with carcinogens and administered isoflavone mixture at 100 and 400 ppm developed adenocarcinomas at incidences of 35% and 29%, respectively, in the prostate and seminal vesicles, whereas the figure was 60% for those maintained on control diet. Feeding of the isoflavone mixture at 100 and 400 ppm significantly inhibited the number of argyrophilic nucleolar organizer regions (AgNORs) in adenocarcinomas of the accessory sex glands as compared to those of rats fed control diet. No influence on the development of neoplastic lesions originating in other organs was noted. The results of this study provide evidence that soybean isoflavones may have potential as chemopreventive agents against carcinogenesis in the prostate.
