Borrmann Ⅳ型胃癌的临床病理特征及预后分析

目的探讨BorrmannⅣ型胃癌患者的临床病理特征和预后生存情况。方法采用队列性回顾性分析2386例行根治性手术治疗的胃癌患者,筛选出BorrmannⅣ型的患者,分析其临床特征及影响预后的因素。结果2386例胃癌患者中BorrmannⅣ型者363例(15.21%)。与非BorrmannⅣ型胃癌相比,BorrmannⅣ型患者的同时性肝转移率、异时性肝转移率、淋巴结转移率、脉管浸润发生率更高,同时发病年龄更趋于年轻化,病理类型更趋于低分化-未分化类型(均P<0.05)。全组患者5年总生存率为49.32%,5年无病生存率为44.61%,其中BorrmannⅣ型患者5年OS、DFS和非BorrmannⅣ型患者比较,差异均有统计学意义(均P<0.001)。亚组分析显示,同为pT2-pT4a或pN0~pN3a期时BorrmannⅣ型与非BorrmannⅣ型胃癌患者5年OS、DFS差异有统计学意义(均P<0.005)。多因素分析显示,肿瘤组织学类型为低分化-未分化类型、肿瘤浸润深度pT分期为T4a~pT4b期、存在淋巴结转移、肿瘤pTNM分期为ⅢA~ⅢC期、术后出现肝转移及术后发生腹膜转移(均P<0.05)是影响BorrmannⅣ型胃癌患者预后的独立危险因素。结论BorrmannⅣ型胃癌具有易发生肝转移、淋巴结转移、腹膜转移且预后差的特点,其预后受多种独立危险因素影响。     

Clinical significance of HLA class I heavy chain expression in patients with gastric cancer

BACKGROUND: Little is known about the relation between HLA-I expression and the prognosis of patients with gastric cancer. The aim of this retrospective study was to clarify the clinical significance of HLA-I heavy chain expression in gastric cancer. METHODS: The study subjects were 202 patients with gastric cancer who had undergone curative surgery. Tumors were examined for expression of HLA-I heavy chain antigens by immunohistochemistry. We analyzed the association of HLA-I heavy chain expression with clinicopathological parameters and patient prognosis. RESULTS: HLA-B/C expression showed association with deeper tumor invasion, higher incidence of lymph node metastasis, more advanced tumor stage, and higher incidence of recurrence. Patients with positive HLA-B/C expression had shorter 5-year overall and 5-year disease-free survival compared with patients whose tumors showed mixed and negative expression (P < 0.05 and 0.01, respectively). In multivariate analysis, although HLA-B/C expression was not recognized as an independent prognostic factor, it was an independent factor in predicting peritoneal recurrence after curative surgery in patients with gastric cancer [relative risk (RR): 9.924, P = 0.003]. CONCLUSION: Expression of HLA-B/C heavy chain is associated with tumor progression, and it could be a significant predictor of peritoneal recurrence after curative surgery in patients with gastric cancer.     

Prognosis and surgical treatment of gastric cancer invading the pancreas

The clinicopathologic characteristics of gastric cancer invading the pancreas have not been determined. Gastrectomy was performed in 282 patients with gastric cancer invading adjacent organs at the Department of Surgery II, Kyushu University Hospital, between 1970 and 1987, and patient data were retrospectively analyzed using univariate and multivariate analyses. Of these patients, 150 (53.2%) had tumors invading the pancreas and 132 had tumors invading adjacent organs other than the pancreas. In both groups, the undifferentiated tissue type with infiltrative growth, lymphatic involvement and lymph node metastasis was common. In cases of pancreas invasion, the extent of lymph node metastasis was more severe, vascular involvement was more frequent and the rate of concomitant liver metastasis was higher. The survival time of the patients with pancreas invasion was shorter compared to patients with cancer invading other organs, and pancreas involvement was one of the independent factors predicting a poor prognosis. With respect to surgical treatment of gastric cancer invading the pancreas, the prognosis was better for cases treated with curative surgery and pancreas resection. Of 39 patients treated with partial resection of the pancreas, the tumor had invaded only the capsule of the pancreas in 18 and the pancreas in the other 21. Pancreas-invasive gastric cancer cells are likely to advance via lymphatic and vascular routes and survival time is shorter, but curative resection can improve the survival rate, and perioperative treatment should be appropriately designed.     

Growth pattern and prognosis of gastric cancer invading the subserosa

Gastric cancer invading the subserosa with infiltrative growth was classified as part of the serosal invasion group and named prognostic serosal invasion positive [ps(+)] histologically. We analyzed clinicopathological features and prognosis of 166 Japanese patients with gastric cancer invading the subserosa, according to the growth pattern. All patients were treated in the Department of Surgery II, Kyushu University. Patients with infiltrative growth (ssγ) were younger and their tumors were frequently undifferentiated compared to findings in those with noninfiltrative growth: expansive (ssα) and intermediate growth (ssß). There was no difference in any other clinicopathological characteristic between those with infiltrative and noninfiltrative growth tumors. The 10-year survival rate was 66.7% for the infiltrative type and 54.2% for the noninfiltrative type, with no statistically significant difference. Lymph node metastasis, curative resection, and extended lymph node dissection, but not growth pattern, proved to be independent prognostic factors, as determined by multivariate analysis. Our findings suggest that it is not the growth pattern which affects the prognosis of ss cancers. Extensive lymph node dissection should be done when lymph node metastasis is present. © Wiley-Liss, Inc.     

血清甲胎蛋白阳性胃癌患者的临床病理学特征及预后分析

背景与目的：血清甲胎蛋白（alpha-fetoprotein,AFP）阳性胃癌是一种临床上比较罕见的胃恶性肿瘤,具有与普通胃癌明显不同的生物学特点,探讨血清AFP阳性胃癌患者的临床病理学特征及影响预后的危险因素。方法：采用回顾性队列研究,分析河北医科大学第四医院外三科2012年1月1日—2015年1月1日行根治性手术治疗的2 386例胃癌患者,筛选出术前血清AFP阳性的患者,分析临床病理学特征及影响预后的因素。结果：2 386例胃癌患者中术前血清AFP阳性者245例（AFP≥20 ng/mL,10.27%）,其余2 141例术前血清AFP均为正常（AFP＜20 ng/mL,89.73%）。与血清AFP阴性组相比,血清AFP阳性组患者的同时性肝转移率、异时性肝转移率、淋巴结转移率、脉管浸润发生率更高（P均＜0.05）。2 386例胃癌患者中共有2 273例（95.26%）获得完整随访资料,全组患者5年总生存率（overall survival,OS）为49.32%,5年无病生存率（disease-free survival,DFS）为44.61%。其中血清AFP阳性者5年OS和DFS分别为37.50%和34.17%,而血清AFP阴性者5年OS和DFS分别为50.90%和45.84%,两组患者的5年OS和DFS差异均有统计学意义（P均＜0.001）。单因素分析显示,术前血清AFP的水平、年龄、病灶部位、肿瘤直径、组织学类型、Borrmann分型、肿瘤浸润深度pT分期、淋巴结转移pN分期、肿瘤pTNM分期、Lauren分型、脉管瘤栓有无、Ki-67阳性比例、术后是否化疗、术后有无肝转移是影响血清AFP阳性胃癌患者预后的危险因素（P均＜0.05）。多因素分析发现,血清AFP水平（P=0.001）、肿瘤组织学类型（P=0.002）、肿瘤浸润深度pT分期（P=0.006）、淋巴结转移pN分期（P=0.014）、肿瘤pTNM分期（P=0.001）、脉管瘤栓有无（P=0.024）和术后有无肝转移（P=0.008）是影响其预后的独立危险因素,而术后辅助化疗（P=0.031）是患者预后的保护性因素。结论：AFP阳性胃癌具有易发生肝转移、淋巴结转移且预后差的特点,血清AFP水平是影响其预后的独立危险因素,随着AFP水平的升高,其预后变差。     

Impact of tumor infiltration pattern into the surrounding tissue on prognosis of the subserosal gastric cancer (pT2b)

Background

The aim of this study was to clarify the impact of infiltration pattern on prognosis in patients with gastric carcinoma invading subserosa.

Methods

Clinicopathologic findings in patients with ssγ pattern (n = 144) were compared with those in patients with ssα/ssβ cancers (n = 222). Prognostic factors of pT2b patients were analyzed by univariate and multivariate analysis.

Results

Compared with the ssα/β group, ssγ gastric cancer exhibited more frequent undifferentiated histology, disseminated lymph node metastasis and perineural invasion. Frequency of postoperative peritoneal recurrence was significantly higher in ssγ gastric cancer (P < 0.05). The 5-year survival rate for patients with ssγ gastric cancer was significantly lower compared with ssα/β group (63.2% vs. 74.8%, respectively; P < 0.05). Lymph node metastasis, vein invasion and infiltrative pattern (ssγ) were significant independent prognostic factors affecting survival in pT2b patients.

Conclusion

In patients with gastric cancer invading the subserosa, infiltrative type growth pattern is closely related to carcinomatosis and poorer prognosis.     

食管癌根治术后三维放疗患者预后的影响因素分析

目的探讨食管癌根治术后行三维放疗患者生存的影响因素。方法回顾分析2005年1月至2009年12月常州市第一人民医院收治的食管癌根治术后行三维放疗的114例患者的临床资料。采用 Kaplan Meier 生存分析法和log rank统计检验各临床病理特征与食管癌根治术后辅助放疗患者预后的相关性。结果114例患者术后放疗后3、5年总体生存率分别为57%和42%;Kaplan Meier生存分析法和log rank统计检验方法分析显示淋巴结转移阳性、淋巴结转移区域数目较多、TNM分期越高、脉管癌栓阳性和Ki 67高表达的食管癌根治术后放疗患者的预后较差,反之则患者预后较好。结论淋巴结转移、淋巴结转移区域数目、TNM分期、脉管癌栓和Ki 67表达是食管癌术后放疗患者生存的影响因素。     

Combined resection of invaded organs in patients with T4 gastric carcinoma

Background. To understand the efficacy of gastrectomy combined with the resection of other organs and to refine the indications for this type of surgery, the records of 156 patients with carcinoma of the stomach directly invading adjacent organs or structures (T4 gastric carcinoma) were analyzed retrospectively. Methods. The patients were divided into three groups, as follows: in group A, curative resection was performed by the combined resection of invaded organs or structures; in group B, although combined resection was performed, curative resection could not be performed because of the extent of lymph node metastasis, liver metastasis, and/or peritoneal metastasis; in group C, combined resection was not performed. Results. In patients with peritoneal or liver metastasis, there was no significant difference in prognosis among the three groups. In patients without peritoneal and liver metastasis, the prognosis of group A was significantly better than that of group B or group C, irrespective of the extent of lymph node metastasis or the number of invaded organs. In these group A patients, the 5-year survival rates of those with localized tumors and no lymph node metastasis, those with localized tumors and lymph node metastasis, those with infiltrating tumors and no lymph node metastasis, and those with infiltrating tumors and lymph node metastasis were 100%, 56.2%, 57.1%, and 13.6%, respectively. Conclusions. Combined resection of involved organs should be carried out with curative intent in patients with localized gastric cancer or infiltrating gastric cancer without lymph node metastasis.

年轻人与中老年人的胃癌特征及预后情况的比较

目的:比较不同年龄段胃癌患者的特征和预后。方法:收集418名胃癌患者,病理确诊为原发性胃腺癌。其中有29名年轻患者［≤40岁,年轻组(YG)］和389名中老年患者［>40岁,年长组(OG)］。分析人口统计学和临床病理特征的差异。结果:相对于中老年组,在年轻病人组中,女性患者的比例较高。5年总体生存YG组比OG组要显著降低。然而,接受根治性切除手术后,YG组与OG组5年生存率没有显著性差异;年轻组显示女性患者生存率明显低于男性患者。肿瘤类型、侵入深度、腹膜转移、远处转移和根治性切除治疗是独立的预后因素。结论:早期发现,早期诊断,积极行根治性切除是提高年轻人胃癌治疗水平及预后的关键,尤其是在女性患者中。     

Effectiveness of continuous hyperthermic peritoneal perfusion for the peritoneal dissemination of gastric cancer

We investigated the effectiveness of continuous hyperthermic peritoneal perfusion (CHPP) for the peritoneal dissemination of gastric cancer. A total 124 patients with advanced gastric cancer were enrolled in this study. Prophylactic CHPP (P-CHPP) was performed in 45 patients who had macroscopic serosal invasion without peritoneal dissemination, and 79 patients without CHPP were a control group. Therapeutic CHPP (T-CHPP) was performed in 21 patients with peritoneal dissemination, and 52 patients without CHPP were a control group. There was no significant difference in 5 year survival between patients treated and not treated with P-CHPP. Univariate analysis showed that location of tumor, tumor diameter, and lymph node metastasis influenced prognosis, but there was no prognostic factor in the Cox proportional regression hazard model. There was no significant difference in 5-year survival between patients treated and not treated with T-CHPP. Univariate analysis showed that degree of peritoneal dissemination and adjuvant chemotherapy influenced prognosis, and the Cox proportional regression hazard model showed that the macroscopic types and degree of peritoneal dissemination affected prognosis. In the patients with CHPP, the incidences of respiratory failure and renal failure were each statistically greater than in the patients undergoing CHPP.     

Prognostic factors for noncurative gastric cancer: univariate and multivariate analyses.

We performed univariate and multivariate analyses of possible prognostic factors related to postoperative clinical course of patients with advanced gastric cancer. Noncurative resection was done for 119 patients with hepatic metastasis, peritoneal seeding, extensive lymph node metastasis, or direct invasion to adjacent organs, either alone or in various combinations. In the univariate analysis, 6 of 17 items such as peritoneal seeding, lymphatic invasion, vascular invasion, mode of invasion, extent of lymphadenectomy, and width of serosal invasion significantly correlated to the prognosis. The multivariate analysis indicated that three inherent pathologic factors, mode of invasion, lymph node metastasis, and hepatic metastasis, and one treatment factor, extent of lymphadenectomy, were significant variables predictive of the prognosis and that the prognosis was expected to be very poor in cases of infiltrative type, nodal involvement to tertiary nodes, presence of hepatic metastasis, and lymphadenectomy less than R3. Prognosis in terms of the extent of lymphadenectomy shows that extensive lymphadenectomy (R3) proved to be significantly effective in prolonging survival time, even after noncurative gastrectomy. We recommend extensive lymphadenectomy to prolong survival time for such patients.     

INVESTIGATION OF THE RELATIONSHIP BETWEEN CELL PROLIFERATIVE ACTIVITY AND INVASION, METASTASIS AND PROGNOSIS OF GASTRIC CANCER

Objective: To evaluated Bromodeoxyuridine (BrdUrd)/DNA doubleparametric method in detection of gastric carcinoma and to analyze the relationships of cellular BrdUrd labeling indices(LI), G2/M-phase fraction(G2/MPE) and DNA content to the depth of invasion, lymphatic vessel invasion, lymphatic node metastasis, peritoneal dissemination and blood vessel invasion and prognosis.Methods: Fresh tumor samples from 60 cases were examined by BrdUrd/DNA doubleparametric flowcytometry. Propidium iodide(PI) was used as fluorescent probe for total cellular DNA and a monoclonal antibody against BrdUrd incorporated into DNA.Fluorescein-labeled goat anti-mouse antibody was used as second antibody. Results: The values of BrdUrd LI in patients with serosa invasion was significantly higher than those without serosa invasion (P＜0.01); there was statistical significance in 5-year survival rate between the two groups (P＜0.01). Both BrdUrd LI and G2/MPF values were significantly higher in patients with lymphatic vessel invasion than those without invasion (P＜0.01); the patients with lymphatic vascular invasion carried a significantly poor prognosis (P＜0.01). Both BrdUrd LI and G2/MPF values were significantly higher in patients with lymphatic node metastasis than those without metastasis (P＜0.01),there was a statistical significance in 5 years survival between these 2 groups. The incidence of lymphatic node metastasis was significantly higher in aneuploid carcinoma (P＜0.05), and the patients with aneuploid carried a significantly poor prognosis (P＜0.05). Patients with peritoneal dissemination had a significantly worse prognosis (P＜0.01). G2/MPF values were significantly higher in patients with blood vessel invasion than thosew ithout invasion (P＜0.01). Conclusion: Cellular BrdUrd LI,G2/MPF and DNA content are related to depth of invasion,lymphatic vessel invasion, peritoneal dissemination, blood vessel invasion and prognosis of gastric carcinoma.     

Long-Term Outcomes after D2 Gastrectomy for Early Gastric Cancer: Survival Analysis of a Single-Center Experience in China

Background: Early gastric cancer (EGC) is well accepted as having a favorable prognosis, but some patients experience an ominous outcome after curative resection. This study was aimed at evaluating predictive factors associated with prognosis of D2 gastrectomies in patients with early gastric cancer. Materials and Methods: A total of 518 patients with early gastric cancer who underwent D2 gastrectomies were reviewed in this study. The clinicopathological features and surgical outcomes were analyzed. The survival rate was estimated using theKaplan-Meier method and compared by log rank test. Prognostic factors were analyzed using a multivariate Cox proportional hazards model. Results: The 5-year survival rate was 90.3%. Tumor infiltration, lymph node metastasis and lymphovascular invasion were significant prognostic factors for survival. Gender, age, tumor size, tumor location, macroscopic type and histological type were not significant prognostic factors. Multivariate analysis indicated that lymph node metastasis was an independent poor prognosis factor. Conclusions: Earlygastric cancers with lymph node metastasis have a relatively poor prognosis after standard surgery. Even after curative resection, patients with EGC with positive lymph nodes should be closely followed and be considered as candidates for comprehensive therapies.

血清甲胎蛋白阳性胃癌患者临床病理特征与预后关系的研究

  目的  探讨血清AFP阳性胃癌（alpha-fetoprotein producing gastric cancer ,AFPGC）与普通型胃癌的差异以及其临床病理特征和预后的关系。  方法  回顾性分析2013年1月至2018年12月在中国人民解放军联勤保障部队第九四〇医院行胃癌手术的患者1 321例,经筛选纳入研究1 144例,分为血清AFP阳性组（53例）与血清AFP阴性组（1 091例）。  结果  AFPGC占同期胃癌患者的4.6%,AFPGC与血清AFP阴性胃癌1、3、5年累计生存率分别为64.2%与92.2%、20.8%与45.1%、13.2%与25.7%,两者术前血清AFP、肿瘤大小、免疫组织化学HER2、肿瘤部位、浸润深度、淋巴结转移、临床分期、脉管侵犯、手术方式、术后肝转移相比,均差异具有统计学意义（P<0.05）。AFPGC单因素以及Cox多因素生存分析显示:临床分期、脉管侵犯、手术方式、术后肝转移以及术后血清AFP再次升高是影响AFPGC预后的危险因素。  结论  AFPGC是一种特殊性的胃癌,具有临床分期晚、易发生术后肝转移和脉管侵犯且预后差,AFPGC患者即使肿瘤原发灶被切除后,仍有较高的肝转移风险,且术前血清AFP水平与患者预后无关,而术后监测血清AFP水平可及时发现肿瘤复发及术后肝转移,此外,早期行胃癌根治术有助于改善患者预后。      

Neoadjuvant chemotherapy with CDDP and 5-fluorouracil for gastric cancer with serosal invasion

Many gastric cancer patients who recur peritoneally are initially diagnosed with serosal invasion. To clarify the usefulness of neoadjuvant chemotherapy with 5-fluorouracil (5-FU) +/- cisplatin (CDDP), neoadjuvant versus no preoperative chemotherapy for gastric cancer with preoperative serosal invasion was investigated. The patients were treated preoperatively with 5-FU 300 mg/m(2)/day for 2 weeks (F group; n=40), 5-FU 300 mg/m(2)/day for 2 weeks + CDDP 15 mg/m(2)/day for 2 days (FP group; n=80) or nothing (C group; n=100). A total of 78% of patients in C, 65.0% in F and 67.5% in FP group were classified as T3 or higher surgically. In patients without peritoneal metastasis, the positive peritoneal lavage cytology was 29.2% in C, 11.8% in F, and 12.2% in FP patients (p=0.0279). Serosal invasion was found histologically in 60.0% of C, 30.0% of F, and 33.8% of FP patients (p=0.001). There were no serious drug reactions and no increases in morbidity or mortality using either regimen. The 5-year survival rate was 47.0% in F and 50.9% in FP patients, but only 33.2% in C patients (p=0.0042). In conclusion, neoadjuvant chemotherapy with 5-FU +/- CDDP for gastric cancer patients with serosal invasion may reduce positive peritoneal cytology, eliminate cancer cells from the serosal surface, and improve prognosis.     

淋巴结转移阴性早期胃癌的临床病理特点及预后分析

目的:探讨淋巴结转移阴性早期胃癌的临床病理特点及其预后因素,为临床治疗提供理论依据。方法:回顾性分析1983年1 月～2003年12月河北医科大学附属邢台人民医院肿瘤外科收治132 例淋巴结转移阴性早期胃癌患者的临床病理特征与预后的关系。结果:淋巴结转移阴性与淋巴结转移阳性早期胃癌在肿瘤直径和浸润深度组间有显著性差异（P<0.05）。 两者在性别、年龄、家族史、肿瘤数目、肿瘤部位、大体类型和组织学类型分组中有显著性差异（P>0.05）。 本组获随访126 例,6 例失访,随访率为95.5% 。3 年生存率为91.3%（115/126）,5 年生存率为84.9%（107/126）。 单因素分析经Kaplan-Merier 分析筛选出浸润深度与淋巴结转移阴性早期胃癌预后关系密切（P=0.001）。 结果表明浸润深度是淋巴结阴性早期胃癌的独立预后因素。黏膜内癌患者的生存率与黏膜下癌者比较,差异有统计学意义（P<0.05）。 结论:浸润深度是淋巴结转移阴性早期胃癌的独立预后因素。术前或术中正确评估早期胃癌的淋巴结转移状态是选择合理的治疗方案和改善预后的重要条件。      

Expression of c-erbB-2 oncoprotein in gastric carcinoma. Immunoreactivity for c-erbB-2 protein is an independent indicator of poor short-term prognosis in patients with gastric carcinoma.

Correlations of c-erbB-2 protein expression with clinical outcomes of gastric carcinomas were studied in 189 gastric carcinomas. There were 23 (12.2%) carcinomas with evidence of c-erbB-2 protein in which the reaction was localized to the cell membrane. There was no significant association between c-erbB-2 staining and the macroscopic or histologic type of the carcinomas. c-erbB-2-stained tumors were more likely to be associated with serosal invasion, nodal involvement, and peritoneal metastasis, than c-erbB-2-unstained ones. In addition, c-erbB-2 was stained in none of early gastric carcinomas. The 5-year survival rates of the c-erbB-2 protein-positive and the protein-negative group were 11% and 50%, respectively. When the c-erbB-2 tissue status and seven clinicopathologic variables as conventional prognostic factors were entered simultaneously into the Cox regression model, serosal invasion, hepatic metastasis, peritoneal metastasis, nodal status, and c-erbB-2 tissue status emerged as independent prognostic variables. The results suggested that c-erbB-2 protein expression might be enhanced in advanced stages during the progression of gastric carcinoma. In this particular group of patients, immunoreactivity for c-erbB-2 protein is an indicator of poor short-term prognosis.     

胸中段食管鳞癌淋巴结转移度及合理清扫范围的临床研究

目的:本研究通过分析胸中段食管鳞癌淋巴结转移规律及淋巴结转移度对预后的影响,探讨合理的淋巴结清扫范围.方法:对129例经现代二野淋巴结清扫术的胸中段食管鳞癌患者的临床资料进行回顾性分析.结果:全组患者淋巴结转移率为56.6%,总淋巴结转移度(阳性淋巴结数/清扫淋巴结总数,LMR)为11.3%,上纵隔淋巴结转移率为43.4%.最常见的淋巴结受累区域为食管旁、右喉返神经旁、贲门及胃左血管旁、隆突下.影响淋巴结转移的主要因素为肿瘤浸润深度、分化程度及肿瘤长度.无淋巴结转移组、淋巴结转移度≤20%组和淋巴结转移度>20%组患者5年生存率分别为50.4%、31.0%和6.8%,结果差异有统计学意义(P=0.000).结论:淋巴结转移度是判断食管癌预后的一个重要因素,胸中段食管癌应该常规行包括双侧上纵隔的现代二野淋巴结清扫术.     

Influence of intraperitoneal chemotherapy to a recurrence pattern of gastric cancer with serosal exposure

We analyzed a recurrence pattern and prognosis of 42 gastric cancer cases with histological serosal exposure of cancer and without macroscopical residual cancer in the operation. These cases received adjuvant MTX-5-FU chemotherapy intraperitoneally. Twenty four patients showed a recurrence of gastric cancer. Twenty two patients died of recurrence, and two patients were still alive with recurrence. Seventeen patients (71%) developed peritoneal seeding, which means intraperitoneal chemotherapy made no influence to the pattern of recurrence of gastric cancer with serosal invasion. All of the recurred patients with Stage II and IIIA gastric cancer and about 60% of the recurred patients with Stage IIB and IV developed peritoneal metastasis. The prognosis of recurred 24 patients showed that 9 patients (38%) were kept alive for more than 3 years, and 5 patients (21%) were kept alive for more than 5 years. Intraperitoneal chemotherapy of MTX-5-FU did not touch the pattern of recurrence of gastric cancer with serosal invasion, but the analysis of the prognosis revealed a possibility of improvement of the prognosis.
