  • Background : Nowadays many researches about it s cure are going on world widely since cancer is one of the most human health threatening diseases. In Chinese and North Korean medicine, Duchesnea india(Audra.) Foche. is practically used to treat many kinds of cancer, but in Korea it is rarely used. So, we need to scientifically identify anti-tumor effects of Duchesnea india(Audra.) Foche. Objective : We are aimed to identify anti-tumor effects of Duchesnea india(Audra.) Foche. on the stomach cancer cells through molecular biologic methods. Material & Methods : We used AGS as stomach cancer cells from American Type Culture Collection. We added the boiled extract of Duchesnea india(Audra.) Foche. $5{\mu}l$(Sample I), $10{\mu}l$(Sample II) to cultural media(ml)for 0,6, 12, 24, 48 hours. We measured the killing effect on stomach cancer cells through Tryphan blue exclusion test and the suppressive effect on viability of stomach cancer cells via MTT assay. the quantitative RT-PCR was used to examine their effect on the revelation of Bcl-2, Bcl-XL, and Bax, which are genes related to apoptosis. We measured change of mitochondria membrane permeability and membrane potential via flow cytometry. Result : 1. The killing effect on stomach cancer cells showed that each test groups killed more stomach cancer cells than the control group with a time(6 hours later) and density dependent manner, which was statistical significance. 2. The suppressive effect on viability of stomach cancer cells showed that each test groups had more suppressive effects on viability of stomach cancer cells than the control group with a time(6 hours later), which was statistical significance. 3. In the test about the revelation of genes related to apoptosis, the revelation of Bcl-2 and Bcl-XL decreased with a density manner which was statistical significance. but the revelation of Bax was not changed with statistical significance. 4. As a result of this test, Duchesnea india(Audra.) Foche. caused apoptosis by decreasing the absorbance of mitochondria with statistical significance. and also induced apoptosis by decreasing the membrane potential of mitochondria. Conclusion : This experiment showed that Duchesnea india(Audra.) Foche. has anti-tumor effect with statistical significance. This is in vitro experiment and basic experiment on Duchesnea india(Audra.) Foche. We hope more progressive researchs on Duchesnea india(Audra.) Foche. will go on and its anti-tumor effects will be more practically identified.

  • Purpose: Despite scientific evidence regarding laparoscopic gastrectomy (LG) for advanced gastric cancer treatment, its application in patients receiving neoadjuvant chemotherapy remains uncertain. Materials and Methods: We used the 2019 Korean Gastric Cancer Association nationwide survey database to extract data from 489 patients with primary gastric cancer who received neoadjuvant chemotherapy. After propensity score matching analysis, we compared the surgical outcomes of 97 patients who underwent LG and 97 patients who underwent open gastrectomy (OG). We investigated the risk factors for postoperative complications using multivariate analysis. Results: The operative time was significantly shorter in the OG group. Patients in the LG group had significantly less blood loss than those in the OG group. Hospital stay and overall postoperative complications were similar between the two groups. The incidence of Clavien-Dindo grade ≥3 complications in the LG group was comparable with that in the OG group (1.03% vs. 4.12%, P=0.215). No statistically significant difference was observed in the number of harvested lymph nodes between the two groups (38.60 vs. 35.79, P=0.182). Multivariate analysis identified body mass index (odds ratio [OR], 1.824; 95% confidence interval [CI], 1.029-3.234; P=0.040) and extent of resection (OR, 3.154; 95% CI, 1.084-9.174; P=0.035) as independent risk factors for overall postoperative complications. Conclusions: Using a large nationwide multicenter survey database, we demonstrated that LG and OG had comparable short-term outcomes in patients with gastric cancer who received neoadjuvant chemotherapy.

  • Purpose: This study was intended to identify the patterns of fatigue and its related factors in patients with stomach cancer during chemotherapy. Methods: Thirty participants (24 males and 6 females) were recruited for this study which utilized a longitudinal and descriptive approach. The research instruments included the Revised Piper Fatigue Scale, Symptom Distress Scale, and Linear Analogue Self Assessment Scale. The participants received 5-FU and Adriamycin at the first week and 5-FU only at the second and third week. The instruments were measured six times in total. The data were analyzed using SPSS 17.0. Results: It was found that fatigue scores in patients with stomach cancer, receiving 5-FU and Adriamycin (FA) regimen, reached the highest level on the third day (F=9.37, p=.024) after the initial infusion, and decreased gradually afterward. The symptom and psychological distress scores illustrated very similar pattern. The concept of multidimensionality of fatigue in patients with stomach cancer was supported in this study, showing that all four dimensions of the scale were positively correlated. Conclusion: The results of this study provided useful information of patients with stomach cancer on fatigue and other related symptoms which they experienced during weekly scheduled chemotherapy with FA regimen.

  • Although significant progress has been made during the past four decades in the treatment of human neoplastic disease, effective chemotherapeutic treatments are nevertheless far from satisfactory to patients suffering from cancer, particularly to those with the stomach cancer which is most prevalent in Korea. To find out the effective anticancer drugs, especially human stomach cancer, we tested cytotoxic activities of several medicinal herbs against human stomach cancer cell line, SNU-1. Evodia officinalis, Melia toosendan, Sinomenium acutum, Galla Haeepensis, Celastrus orbiculatus and Taxus caespitosa showed a significant cytotoxic activities.

  • The purpose of this study is to examine the degree of health promotion behavior among stomach cancer patients and its relevant factors, such as belief, family support, and self-esteem etc. To investigate factors affecting health promotion behavior among stomach cancer patients, a survey was conducted through personal interviews with 153 stomach cancer patients who came to two hospitals in Daejeon from June to July, 2008. Questions were about respondents' general characteristics, properties related to stomach cancer, health belief & family support for the disease, and self-esteem. According to the results of multi-variate regression analysis, factors affecting health promotion behavior included age, treatment type, benefit, barrier, family support, and self-esteem which explained 66.6%. Public health and medical interventions are necessary to improve health promotion behavior among stomach cancer patients by improving benefit, family support, and self-esteem and reducing barrier.

  • The purpose of this study is to compare the difference between stomach cancer stages and related factors according to the diagnosis path. The self-administered questionnaire was filled out by 375 inpatients with primary stomach cancers who had been scheduled at Chungnam National University Hospital were targeted for the survey during the period from August 1st 2010 to March 31st 2013. Rogistic regression model were estimated to identify related factors between Medical checkups group and symptom group. As a results, the study suggests that early checkups is important because ratio of early stomach cancer is higher in Medical checkups group than in symptom group(p=0.001). And if there was a symptom at diagnosis of stomach cancer, stomach cancer stage appeared to have a strong possibility(p=0.001). If cancer screening has been widely implemented and supported by a large scale prospective studies will be possible even in the most appropriate tests and interval estimation for the country.

  • Purpose: Evidence exists that dysregulation of apoptosis is involved in the pathogenesis of cancer development. Fasassociated death domain (FADD) protein, an adaptor protein of death receptors, is a critical regulatory component of the extrinsic cell- death pathway that exerts its pro-apoptotic effect upon binding with death receptors. Expression of the FADD protein has not been reported in stomach cancer. The aim of this study was to explore the expression status of the FADD protein in stomach cancers. Materials and Methods: In the current study, we analyzed the expression of the FADD protein in 60 advanced stomach cancer by using immunohistochemistry and a tissue microarray approach. Results: Immunopositivity (defined as $\geq\30\%$) was observed for the FADD protein in 23 ($38\%$) of the 60 cancers. Normal gastric mucosal cells showed expression of the FADD protein. Conclusion: Taken together, these results indicate that decreased expression of the FADD protein is a frequent event in stomach cancers and suggest that to avoid apoptosis, stomach cancer cells in vivo may need loss of FADD expression, which might contribute to tumor development.

  • The present study was conducted to evaluate the food and nutrients intakes of stomach cancer patients in the Daegu and Gyeongbuk areas in order to find out the dietary risk factors for stomach cancer. The subjects of the study were 102 patients who had recently been diagnosed with stomach cancer at the Gyeongbuk National University Hospital. The control subjects were 105 people including patients from the Department of Orthopedic Surgery and healthy volunteers who did not have any gastrointestinal diseases. Estimates of nutrients intakes were determined from the food intake frequency data obtained by individual interviews using questionnaires. The mean daily calorie intakes of the control and the case groups were not significantly different. However the energy intake from protein was significantly higher in the case group as compared to the control group. With regard to the nutrients intakes, the case subjects consumed significantly higher amounts of nutrients such as protein, calcium, sodium, phosphorus and niacin than the control group. The case group showed a tendency to consume higher amount of protein, fat, calcium and iron from animal food sources. In the present study dietary factors which were suspected as being risk factors for stomach cancer included high consumption of animal foods, specific nutrients such as protein, sodium and niacin, specific food groups such as meat, spices, and low consumption of fruits and mushrooms. Therefore, it is recommended that more extensive and systematic surveys be conducted to confirm the risk factors for stomach cancer, taking into consideration the dietary cultural characteristics of this region.

  • The relationship between sodium intake and stomach cancer risk has been studied much in Japan but a great portions still remain controversial. There has been few studies on relationship between sodium intake and stomach cancer in Korea. The goal of this nested case-control study is to investigate the association between sodium intake and stomach cancer risk in a rural county of Korea We estimated sodium intake indirectly by the threshold of salt-water taste of patients. This study was based on both of the data from 'Kangwha Cohort Study' which had been conducted from March 1985 and 'Kangwha Community Cancer Registry' which had been launched on July in 1982 by the College of Medicine, Department of Preventive Medicine. Yonsei University. A total of 145 patients who developed stomach cancer in Kangwha County were initially recruited as the case group. We tried to get two community-controls per stomach cancer case by matching age and gender. Finally we got information from 90 cases and 146 controls about the threshold of the salt taste and preference of salty food and so on. Some 79% of the information about ease group came from proxy respondents and 56% among controls. Risk ratios of developing stomach cancer adjusted for smoking, body mass index and self-stated health level were estimated. No statistically significant association between the threshold of salt taste and stomach cancer risk found in this study. We recommend some further studies utilizing urinary salt excretion, diet record method for better estimating of salt intake with a paticular emphasis on interaction effect between salty and spicy food in hospital-based case-control study designs.

  • Purpose: The aim of this study was to investigate the relationship between the 5-year survival rate, socioeconomic status, and SEER (Surveillance Epidemiology and End Results) stage of stomach, colorectal, breast and cervical cancer patients. Methods: A total of 11,770 cases of four target cancers, which were diagnosed during 2005-2007, were extracted from the database of Gwangju-Jeonnam Regional Cancer Registry. The subjects of the study were 11,770 including stomach (n=5,479), colorectal (n=3,565), breast (n=1,516) and cervical cancers (n=710). Cox's proportional hazards model was used to obtain the hazards ratio (HR) according to the SEER stage and socioeconomic status. Results: Stomach cancer had a significantly higher HR in the medical aid recipients (HR=1.39), and the group below 20% (HR=1.20) compared to the group with the highest income level. Colorectal cancer had a significantly higher HR in the medical aid recipients (HR=1.26) than in the group with the highest income level. In addition, stomach, colorectal, breast and cervical cancers had a significantly higher HR according to the SEER stage in regional direct (stomach=4.10, colorectal=1.76, breast=12.90, cervical=3.10), regional lymph only(stomach=2.58, colorectal=2.33, breast=4.32, cervical=4.43), regional both (stomach=6.74 colorectal=3.04, breast=15.57 cervical=6.50), and regional NOS (Not Otherwise Specified)/distant (stomach=17.53, colorectal=11.53, breast=25.34, cervical=26.51) than in situ and localized only. Conclusion: In order to increase the cancer survival rate, a support system for early detection and early treatment of cancer should be established for groups with low individual income levels, and regular health checkups and management measures should be actively implemented through the National Cancer Screening Program.
