RESUMO
Gastric cancer is one of the most common malignant tumors in the digestive system in China. Few comprehensive practice guidelines for early gastric cancer in China are currently available. Therefore, we created the Chinese national clinical practice guideline for the prevention, diagnosis, and treatment of early gastric cancer. This clinical practice guideline (CPG) was developed in accordance with the World Health Organization's recommended process and with the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) in assessing evidence quality. We used the Evidence to Decision framework to formulate clinical recommendations to minimize bias and increase transparency in the CPG development process. We used the Reporting Items for practice Guidelines in HealThcare (RIGHT) statement and the Appraisal of Guidelines for Research and Evaluation II (AGREE II) as reporting and conduct guidelines to ensure completeness and transparency of the CPG. This CPG contains 40 recommendations regarding the prevention, screening, diagnosis, treatment, and follow-up of early gastric cancer based on available clinical studies and guidelines. We provide recommendations for the timing of Helicobacter pylori eradication, screening populations for early gastric cancer, indications for endoscopic resection and surgical gastrectomy, follow-up interval after treatment, and other recommendations. This CPG can lead to optimum care for patients and populations by providing up-to-date medical information. We intend this CPG for widespread adoption to increase the standard of prevention, screening, diagnosis, treatment, and follow-up of early gastric cancer; thereby, contributing to improving national health care and patient quality of life.

OBJECTIVES: To observe the therapeutic effect of acupuncture at Shuitong and Shuijin points on preventing sufentanil-induced cough and its influence on hemodynamics in general anesthesia induction. METHODS: A total of 80 patients scheduled for elective surgery undergoing general anesthesia were randomly divided into an observation group (40 cases) and a control group (39 cases,1 case eliminated). In the control group, the routine anesthesia was performed,with intravenous injection of 1% sufentanil citrate 0.5 µg/kg, 1% propofol (total amount was calculated according to 2 mg/kg) and cisatracurium besilate 0.2 mg/kg. In the observation group, before routine anesthesia induction, acupuncture was applied to Shuitong and Shuijin points on the right and the needles were retained for 30 min. During anesthesia induction, the complications i.e. cough and chest wall stiffness were observed, and the systolic blood pressure (SBP), heart rate (HR) and pulse oxygen saturation (SpO2) were monitored 5 min after the patients entered the operation room (T0),at the moment of intravenous injection of sufentanil (T1) and 2 min after sufentanil injection (T2) , 1 min before and after endotracheal intubation (T3,T4) of the two groups, respectively. RESULTS: During anesthesia induction,the condition of mild, moderate and severe cough in the observation group was superior to that of the control group (P<0.05), the total cases of cough and its total incidence were lower than those of the control group (P<0.05). Two cases of chest wall stiffness were present in each group, but without statistical difference between the two groups (P>0.05). In comparison of SBP, HR and SpO2 at T0, T1, T2, T3 and T4, the differences were not significant statistically between the two groups (P>0.05). SBP and HR increased at T2 when compared with those at T1 in the control group (P<0.05), but there was no statistical difference in SpO2 (P>0.05); while, the differences in SBP, HR and SpO2 were not significant at T2 when compared with those at T1 in the observation group (P>0.05). CONCLUSIONS: Acupuncture at Shuitong and Shuijin points can effectively prevent from sufentanil-induced cough, reduce the severity of cough and stabilize the hemodynamic indicators.

Cancer pain, especially the moderate-to-severe pain experienced by patients with advanced cancer, is still one of the most challenging clinical problems. The current mainstream pharmacological treatment for cancer pain involves applying opioid medications and other pain-killing drugs. However, analgesic drugs have many adverse effects such as addiction, tolerance, and other formidable clinical and social issues. Thus, finding a new therapeutic approach to treat cancer pain is essential. Traditional Chinese medicine (TCM) has been increasingly applied in clinical practice because of its good efficacy and few side effects. However, its mechanisms of action in treating pain are still under investigation. The most important mechanism of cancer pain is that a large amount of pain-causing substances are secreted from cancer cells and promote their growth and invasion. The physical and chemical stimulations of these substances exist along with the cancer growth, leading to constantly increased pain sensation. Whether cancer pain can be alleviated by inhibiting cancer cells from releasing the substances and changing the microenvironment around the cancer mass, or even by eliminating pain-causing substances, is largely unknown. Based on TCM theory, this study reported that the aforementioned approach could effectively manage different cancer pains by tonifying qi, clearing and activating channels and meridians, and strengthening body resistance. The TCM therapies activate blood circulation, remove blood stasis, and nourish the heart. Commonly used Chinese herbal drugs include Corydalis yanhusuo, Angelica dahurica, and Ligusticum chuanxiong. Instead of using conventional analgesics to reduce pain, we should focus on using TCM modalities to alleviate cancer pain and increase the quality of life in patients suffering from cancer pain. TCM should provide us with a new strategy for managing cancer pain.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is an acute respiratory infectious disease that is often accompanied by diarrhea, patients with symptoms such as diarrhea are more likely to develop severe pneumonia, while diarrhea is the most prominent among atypical symptoms. The incidence of diarrhea in COVID-19 patients is 2.0% to 49.5%. Moxibustion has been proven to have a therapeutic effect on diarrhea; however, there is no high-quality evidence on moxibustion for diarrhea in COVID-19 patients. This study was designed to evaluate the effectiveness and safety of moxibustion for the treatment of diarrhea in patients with COVID-19. METHODS: Randomized controlled trials from December 2019 to December 2021 will be included without restrictions on language or publication date. PubMed, EMBASE, Cochrane Library, Web of Science, Chinese Biomedical Databases, China National Knowledge Infrastructure, Wanfang database, and VIP database will be searched. Two researchers will independently select studies, extract data and evaluate study quality. Cochrane risk of bias tool for randomized trials will be used to assess the risk of bias of included studies. Statistical analyses will be performed using the Review Manager V.5.3 and stata 14.0. RESULTS: The results of this meta-analysis will be submitted to a peer-reviewed journal for publication. CONCLUSION: This study will provide evidence for whether moxibustion therapy is beneficial to the treatment of diarrhea in COVID-19. ETHICS AND DISSEMINATION: Ethical approval is not required for this study. The systematic review will be published in a peer-reviewed journal, presented at conferences, and shared on social media platforms. This review would be disseminated in a peer-reviewed journal or conference presentations. PROSPERO REGISTRATION NUMBER: CRD42022302933.

BACKGROUND: The clinical values of inflammatory and nutritional markers remained unclear for gastric cancer with neoadjuvant chemotherapy (NACT). METHODS: The inflammatory, nutritional markers and their changes were analyzed for locally advanced gastric cancer with NACT. The predictive value was evaluated by the Cox proportional hazards regressions under three hypothesized scenarios. The nomograms including independent prognostic factors were plotted for survival prediction. RESULTS: A total of 225 patients were included in the study. The neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio, lymphocyte-to-monocyte ratio (LMR), systemic immune-inflammation index, and hemoglobin (Hgb) were significantly reduced, and the body mass index was significantly increased after NACT (all P < 0.05). The pre-NACT NLR [hazard ratio (HR) = 1.176, P = 0.059] showed a trend to correlate with the overall survival (OS) when only pre-NACT markers available; The post-NACT Hgb (HR = 0.982, P = 0.015) was the independent prognostic factor when only post-NACT markers available; The post-NACT Hgb (HR = 0.984, P = 0.025) and the change value of LMR (HR = 1.183, P = 0.036) were the independent prognostic factors when both pre- and post-NACT markers available. The nomogram had a similar Harrell's C-statistic compared to ypTNM stage (0.719 vs. 0.706). CONCLUSION: For locally advanced gastric cancer, the NACT could significantly decrease some inflammatory markers. The pre-NACT NLR, the post-NACT Hgb and the change value of LMR had some values in survival prediction combined with age, sex, tumor location and the clinical stages under different clinical scenarios. The elevated initial NLR, the preoperative anemia and the greater change value of LMR implied a poor prognosis.

BACKGROUND: Garlic may be protective against Helicobacter pylori infection and gastric cancer development. We conducted this study to quantitatively update evidence on garlic intake and gastric cancer with the inclusion of most recent cohort studies and qualitatively summarize epidemiological studies of garlic consumption and Helicobacter pylori infection. MATERIALS AND METHODS: PubMed, Embase, MEDLINE, and Cochrane Library were searched on April 2018. We conducted a meta-analysis to determine whether garlic intake reduced gastric cancer risk using random-effect models and a systematic review to summarize evidence on the association between garlic consumption and Helicobacter pylori infection. Risk of bias was assessed using tools of Cochrane risk of bias and Robins-I for randomized and nonrandomized studies, respectively. RESULTS: Meta-analysis of 18 studies (142 921 subjects) demonstrated high garlic consumption (as comparing the highest category to the lowest) was associated with a reduced gastric cancer risk (OR = 0.51, 95% CI = 0.44-0.57). This association became nonsignificant if only derived from the prospective studies (OR = 0.95, 95% CI = 0.66-1.24). Thirteen studies (4889 participants) were included in the systematic review for garlic consumption and Helicobacter pylori infection; ten of which found no significant results. The majority of these studies were poor in quality given the small sample size and high risk of bias. CONCLUSIONS: Pooled evidence, mainly from case-control studies, suggested a significant inverse association of garlic intake with gastric cancer risk. Given the limitations of included studies, current epidemiological evidence is not sufficient to reach any definite conclusion regarding the association of garlic with Helicobacter pylori infection.

Gastric cancer is one of the leading causes of cancer-related deaths worldwide. Among which, about 1%-3% of gastric cancer patients were characterized by inherited gastric cancer predisposition syndromes, knowing as hereditary diffuse gastric cancer (HDGC). Studies reported that CDH1 germline mutations are the main cause of HDGC. With the help of rapid development of genetic testing technologies and data analysis tools, more and more researchers focus on seeking candidate susceptibility genes for hereditary cancer syndromes. In addition, National Comprehensive Cancer Network (NCCN) guidelines recommend that the patients of HDGC carrying CDH1 mutations should undergo prophylactic gastrectomy or routine endoscopic surveillances. Therefore, genetic counseling plays a key role in helping individuals with pathogenic mutations make appropriate risk management plans. Moreover, experienced and professional genetic counselors as well as a systematic multidisciplinary team (MDT) are also required to facilitate the development of genetic counseling and benefit pathogenic mutation carriers who are in need of regular and standardized risk management solutions. In this review, we provided an overview about the germline mutations of several genes identified in HDGC, suggesting that these genes may potentially act as susceptibility genes for this malignant cancer syndrome. Furthermore, we introduced information for prevention, diagnosis and risk management of HDGC. Investigations on key factors that may have effect on risk management decision-making and genetic data collection of more cancer syndrome family pedigrees are required for the development of HDGC therapeutic strategies.
RESUMO
BACKGROUND/AIMS: Nonalcoholic steatohepatitis includes steatosis along with liver inflammation, hepatocyte injury and fibrosis. In this study, we investigated the protective role and the potential mechanisms of a traditional Chinese medicine ShenFu (SF) preparation in an in vitro hepatic steatosis model. METHODS: In palmitic acid (PA)-induced murine hepatic AML12 cell injury, effects of SF preparation on cellular apoptosis and intracellular triglyceride (iTG) level were assessed using TUNEL and TG Colorimetric Assay. Reactive oxygen species (ROS) and mitochondrial membrane potential (MMP) levels were measured using DCF and JC-1 assay. Cytokine levels were evaluated using ELISA assay. Immunoblot was used to compare the activation level of c-Jun N terminal kinase (JNK), NADPH oxidase (Nox4), and NFκB pathways. RESULTS: Addition of SF preparation prevented PA-mediated increase of apoptosis and iTG as well as IL-8 and IL-6. In PA-treated cell, SF preparation reduced the level of Nox4 and ROS, while increasing the level of MMP and the expression of manganese superoxide dismutase (MnSOD) and catalase, indicating emendation of mitochondrial dysfunction. Nox4 inhibitor GKT137381 prevented PA-induced increase of ROS and apoptosis, while decreasing iTG slightly and not influencing the level of IL-8 and IL-6. SF preparation prevented PA-induced upregulation of phospho-JNK. JNK inhibitor SP600125 prevented PA-mediated increase of Nox4, IL-8, IL-6 and iTG. Nuclear translocation of NFκB/p65 was detected in PA-treated cells, which was prevented by SF preparation. An IκB degradation inhibitor, BAY11-7082, prevented PA-induced increase of IL-8 and IL-6 as well as iTG, whereas it only decreased ROS levels slightly and showed no influence on cellular apoptosis. CONCLUSION: SF preparation shows a beneficial role in prevention of hepatocyte injury by attenuating oxidative stress and cytokines production at least partially through inhibition of JNK/Nox4 and JNK/NFκB pathway, respectively.

AIM: To determine the level of consensus on the definition of colorectal anastomotic leakage (CAL) among Dutch and Chinese colorectal surgeons. METHODS: Dutch and Chinese colorectal surgeons were asked to partake in an online questionnaire. Consensus in the online questionnaire was defined as > 80% agreement between respondents on various statements regarding a general definition of CAL, and regarding clinical and radiological diagnosis of the complication. RESULTS: Fifty-nine Dutch and 202 Chinese dedicated colorectal surgeons participated in the online survey. Consensus was found on only one of the proposed elements of a general definition of CAL in both countries: 'extravasation of contrast medium after rectal enema on a CT scan'. Another two were found relevant according to Dutch surgeons: 'necrosis of the anastomosis found during reoperation', and 'a radiological collection treated with percutaneous drainage'. No consensus was found for all other proposed elements that may be included in a general definition. CONCLUSION: There is no universally accepted definition of CAL in the Netherlands and China. Diagnosis of CAL based on clinical manifestations remains a point of discussion in both countries. Dutch surgeons are more likely to report 'subclinical' leaks as CAL, which partly explains the higher reported Dutch CAL rates.

OBJECTIVE: To investigate the safety and efficacy of organ preservation surgery or "watch and wait" strategy for rectal cancer patients who are evaluated as clinical complete response(cCR) or near-cCR following neoadjuvant chemoradiotherapy (nCRT). METHOD: From March 2011 to June 2016, 35 patients with mid-low rectal cancers who were diagnosed as cCR or near-cCR following nCRT underwent organ preservation surgery with local excision or surveillance following "watch and wait" strategy in the Peking University Cancer Hospital. All the patients received re-evaluation and re-staging 6-12 weeks after the completion of nCRT, according to Habr-Gama and MSKCC criteria for the diagnosis of cCR or near-cCR. The near-cCR patients who received local excision and were pathologically diagnosed as T0Nx were also regarded as cCR. The end-points of this study included organ-preservation rate (OPR), sphincter-preservation rate (SPR), non-re-growth disease-free survival (NR-DFS), stoma-free survival, cancer-specific survival (CSS) and overall survival(OS). Kaplan-Meier curve was used to estimate the survival data at 3 years. RESULTS: A total of 35 cases were analyzed including 24 males (68.6%) and 11 females (31.4%). The median age was 60 (range 37-79) years and the median distance from tumor to anal edge was 4(2-8) cm. Thirty-three patients received 50.6 Gy/22f IMRT with capecitabine and two patients received 50 Gy/25f RT with capecitabine. The cCR and near-cCR rates were 74.3%(26/35) and 25.7%(9/35) respectively. Excision biopsy was performed in 4 near-cCR cases to confirm the diagnosis of cCR. The non-re-growth DFS rate was 14.3%(5/35) and the median time of tumor re-growth was 6.7 (4.7-37.4) months. In five patients with tumor re-growth, four were salvaged by radical rectal resections and one received local excision. The distant metastasis rate was 5.7%(2/35), one patient presented resectable liver metastasis and received radical resection, another patient presented multiple bone metastases and was still alive. The median follow-up time was 43.7(6.1-71.4) months. At three years, the organ-preservation rate was 88.6%(31/35), the sphincter-preservation rate was 97.1% (34/35). No local recurrence was observed in five patients who received salvage surgery. The non-re-growth DFS was 94.0%. Three patients died of non-rectal cancer related events. The cancer-specific survival was 100%, the overall survival was 92.7% and the stoma-free survival rate was 90.0%. CONCLUSIONS: Organ preservation surgery or "watch and wait" strategy for cCR or near-cCR patients is feasible and achieves good outcomes. This strategy can be an alternative to standard care, improve patient's quality of life and facilitate tailored treatment for mid-low rectal cancer following nCRT, however, it should be cautiously applied in near-cCR patients before local excision biopsy.

Locoregional spread of abdominopelvic malignant tumors frequently results in peritoneal carcinomatosis (PC). The prognosis of PC patients treated by conventional systemic chemotherapy is poor, with a median survival of < 6 mo. However, over the past three decades, an integrated treatment strategy of cytoreductive surgery (CRS) + hyperthermic intraperitoneal chemotherapy (HIPEC) has been developed by the pioneering oncologists, with proved efficacy and safety in selected patients. Supported by several lines of clinical evidence from phasesâ I, II and III clinical trials, CRS + HIPEC has been regarded as the standard treatment for selected patients with PC in many established cancer centers worldwide. In China, an expert consensus on CRS + HIPEC has been reached by the leading surgical and medical oncologists, under the framework of the China Anti-Cancer Association. This expert consensus has summarized the progress in PC clinical studies and systematically evaluated the CRS + HIPEC procedures in China as well as across the world, so as to lay the foundation for formulating PC treatment guidelines specific to the national conditions of China.

Traditional Chinese medicine (TCM) has been a major part of healthcare in China, and has extensively affected medicine and healthcare in surrounding countries over a long period of time. In the fight against cancer, certain anticancer remedies using herbs or herbal formulas derived from TCM have been developed for the management of malignancies. Furthermore, there are clinical trials registered for the use of herbal remedies in cancer management. Herbal medicine has been used as part of combined therapies to reduce the side-effects of chemotherapy, including bone marrow suppression, nausea and vomiting. Herbal remedies have also been used as chemopreventive therapies to treat precancerous conditions in order to reduce the incidence of cancer in high-risk populations. Emerging evidence has revealed that herbal remedies can regulate the proliferation, apoptosis, adhesion and migration of cancer cells. In addition to this direct effect upon cancer cells, a number of herbal remedies have been identified to suppress angiogenesis and therefore reduce tumour growth. The inhibition of tumour growth may also be due to modifications of the host immune system by the herbal treatment. However, the precise mechanisms underlying the therapeutic effects of herbal remedies remain poorly understood and are yet to be fully elucidated. The present study aims to summarize the current literature and clinical trial results of herbal remedies for cancer treatment, with a particular focus on the recent findings and development of the Yangzheng Xiaoji capsule.
RESUMO
AIM: The ACCElox registry was set up to assess therapeutic management of early-stage colon cancer with oxaliplatin/5-fluorouracil (5-FU)-based regimen and the duration of adjuvant chemotherapy in current clinical practice. METHODS: This prospective observational study was conducted between 2006 and 2008 in 19 countries on 1548 newly diagnosed patients with stage II/III colon cancer, who had complete resection of the primary tumor and treated with at least one dose of oxaliplatin. The patient/disease characteristics, dose intensity, toxicity management, treatment delay and duration of disease-free survival (DFS)/relapse were assessed. RESULTS: About 73 and 27% of the patients were diagnosed with stage III (Dukes C) and stage II (Dukes B2) colon cancer, respectively. Overall, 74.4% patients completed the prescribed chemotherapy (FOLFOX 88%) and 97.6% patients received at least two cycles of oxaliplatin chemotherapy. The median actual dose intensity of oxaliplatin per cycle was 85 mg/m(2) . Relapse within 3 years occurred in 18.4% of patients with similar rate in all three groups (FOLFOX - 18.1%, FLOX - 19%, XELOX - 18.6%). At 3 years follow-up only 72 deaths were reported. The most common adverse events (AEs) at any cycle were neutropenia (63.9%), thrombocytopenia (23.3%), diarrhea (9.7%), sensory neuropathy (4.5%) and infection (2.6%). Disorders of central and peripheral nervous systems were frequently reported AEs at 6 months (54.3%, grade ≥1) and 12 months (36.4%, grade ≥1) of follow-up. CONCLUSION: Majority of the patients completed the prescribed oxaliplatin/5-FU regimen. There was no significant difference in the DFS among these regimens. Our results confirm the favorable benefit/risk profile of oxaliplatin/5-FU-based regimens in this setting in clinical practice.

BACKGROUND: Our aim is to evaluate the safety and efficacy of two treatment strategies, hyperthermic intraperitoneal chemotherapy (HIPEC) plus simultaneous versus staged cytoreductive surgery (CRS) in patients with occult peritoneal metastasis of gastric cancer (GC). METHODS: We retrospectively reviewed 26 GC patients who were potential curatively resectable by pre-operative evaluation and found occult peritoneal metastasis by diagnostic laparoscopy. Patients were treated by HIPEC plus either simultaneous CRS (CRS+HIPEC group, n = 11) or staged CRS after systematic chemotherapy (HIPEC+Chemo+CRS group, n = 15). RESULTS: There is no mortality observed in both groups. The treatment complications in two group is comparable (P = 0.683), with 26.7% (4/15) in HIPEC+Chemo+CRS group, and 36.4% (4/11) in CRS+HIPEC group, respectively. The compliance of patients undergoing subsequent chemotherapy is higher in HIPEC+Chemo+CRS group (93.3%, 14/15) than that of CRS+HIPEC group (45.5%, 5/11) (P = 0.021). The mean interval time between CRS and first post-CRS systematic chemotherapy were 42.0 ± 12.0 days in HIPEC+Chemo+CRS group versus 69.8 ± 36.3 in CRS+HIPEC group (P = 0.163), respectively. The median OS in the HIPEC+Chemo+CRS group was 25.0 months, while 28.2 months in the CRS+HIPEC group (P = 0.738). CONCLUSION: For resectable GC patients with laparoscopic findings of occult peritoneal metastasis, HIPEC plus staged CRS is with better tolerance and compliance than simultaneous CRS.

BACKGROUND: The CLASSIC trial was done to compare adjuvant capecitabine plus oxaliplatin versus observation after D2 gastrectomy for patients with stage II or III gastric cancer. The planned interim analysis of CLASSIC (median follow-up 34 months) showed that adjuvant capecitabine plus oxaliplatin significantly improved disease-free survival, the primary endpoint, compared with observation after D2 gastrectomy. We report the 5-year follow-up data from the trial. METHODS: CLASSIC was a phase 3, randomised, open-label study done at 35 cancer centres, medical centres, and hospitals in China, South Korea, and Taiwan. Patients with stage II-IIIB gastric cancer who underwent curative D2 gastrectomy were randomly assigned (1:1) after surgery to receive adjuvant chemotherapy with capecitabine and oxaliplatin (eight 3-week cycles of oral capecitabine 1000 mg/m(2) twice daily on days 1-14 plus intravenous oxaliplatin 130 mg/m(2) on day 1) for 6 months or observation alone. Randomisation was stratified by country and disease stage with a permuted block (size four) design. Neither patients nor investigators were masked to treatment assignment. The primary outcome was 3-year disease-free survival in the intention-to-treat population. This analysis presents the final preplanned assessment of outcomes after 5 years. The study is registered with ClinicalTrials.gov, NCT00411229. FINDINGS: We enrolled 1035 patients: 520 were randomly assigned to adjuvant capecitabine and oxaliplatin, and 515 to observation. Median follow-up for this analysis in the intention-to-treat population was 62·4 months (IQR 54-70). 139 (27%) patients had disease-free survival events in the adjuvant capecitabine and oxaliplatin group versus 203 (39%) patients in the observation group (stratified hazard ratio [HR] 0·58, 95% CI 0·47-0·72; p<0·0001). Estimated 5-year disease-free survival was 68% (95% CI 63-73) in the adjuvant capecitabine and oxaliplatin group versus 53% (47-58) in the observation alone group. By the clinical cutoff date, 103 patients (20%) had died in the adjuvant capecitabine and oxaliplatin group versus 141 patients (27%) in the observation group (stratified HR 0·66, 95% CI 0·51-0·85; p=0·0015). Estimated 5-year overall survival was 78% (95% CI 74-82) in the adjuvant capecitabine and oxaliplatin group versus 69% (64-73) in the observation group. Adverse event data were not collected after the primary analysis. INTERPRETATION: Adjuvant treatment with capecitabine plus oxaliplatin after D2 gastrectomy should be considered for patients with operable stage II or III gastric cancer.

OBJECTIVE: To evaluate the efficacy and safety profile of XELOX (capecitabine/oxaliplatin) in patients with locally advanced gastric cancer who underwent curative D2 resection in China. METHODS: This is a subgroup analysis of Chinese patients in the capecitabine and oxaliplatin adjuvant study in stomach cancer (CLASSIC study), which was a randomised, open-label, multicentre, parallel-group, phase III( study in the Asia-Pacific region. A total of 100 gastric cancer patients who received curative D2 gastrectomy were enrolled in this study and were randomly assigned to either XELOX group (oral capecitabine combined with intravenous oxaliplatin chemotherapy) or the control group (surgery alone). This study aims to compare the 3-year disease-free between the two groups. RESULTS: Subgroup analysis showed that 3-year DFS rate were 78% and 56% in XELOX and control group, respectively. The risk of relapse in XELOX group was reduced by 59% (HR=0.41, 95%CI:0.20-0.85, P=0.013), compared with the control group. The 3-year overall survival rate were 78% and 66% in XELOX and control group, with no statistically significant difference (HR=0.55, 95%CI:0.26-1.16, P=0.110). CONCLUSION: Adjuvant XELOX chemotherapy following D2 gastrectomy may improve the survival in patients with advanced gastric cancer in China.

BACKGROUND: Golgi phosphoprotein 3 (GOLPH3) has been validated as a potent oncogene involved in the progression of many types of solid tumors, and its overexpression is associated with poor clinical outcome in many cancers. However, it is still unknown the association of GOLPH3 expression with the prognosis of colorectal cancer (CRC) patients who received 5-fluorouracil (5-FU)-based adjuvant chemotherapy. METHODS: The expression of GOLPH3 was determined by qRT-PCR and immunohistochemistry in colorectal tissues from CRC patients treated with 5-FU based adjuvant chemotherapy after surgery. The association of GOLPH3 with clinicopathologic features and prognosis was analysed. The effects of GOLPH3 on 5-FU sensitivity were examined in CRC cell lines. RESULTS: GOLPH3 expression was elevated in CRC tissues compared with matched adjacent noncancerous tissues. Kaplan-Meier survival curves indicated that high GOLPH3 expression was significantly associated with prolonged disease-free survival (DFS, P = 0.002) and overall survival (OS, P = 0.011) in patients who received 5-FU-based adjuvant chemotherapy. Moreover, multivariate analysis showed that GOLPH3 expression was an independent prognostic factor for DFS in CRC patients treated with 5-FU-based chemotherapy (HR, 0.468; 95%CI, 0.222-0.987; P = 0.046). In vitro, overexpression of GOLPH3 facilitated the 5-FU chemosensitivity in CRC cells; while siRNA-mediated knockdown of GOLPH3 reduced the sensitivity of CRC cells to 5-FU-induced apoptosis. CONCLUSIONS: Our results suggest that GOLPH3 is associated with prognosis in CRC patients treated with postoperative 5-FU-based adjuvant chemotherapy, and may serve as a potential indicator to predict 5-FU chemosensitivity.

The present study examined, in vitro and in vivo, the potential antitumour effects of Yangzheng Xiaoji (YZXJ), a traditional Chinese medical formula used in cancer treatment, on osteosarcoma, a tumour type recently found to be sensitive to YZXJ. The human osteosarcoma cell line MG63 was used in cell-matrix adhesion and cell growth assays. The same cell line was used in an in vivo tumour model by establishing subcutaneous osteosarcoma xenografts. Oral and intraperitoneal routes were used to deliver the YZXJ extract. The effect of YZXJ on the activation of focal adhesion kinase (FAK) and paxillin was evaluated by immunofluorescence methods. It was found that YZXJ exhibited a significant inhibitory effect on cell-matrix adhesion as demonstrated by a cell-based assay and electric cell-substrate impedance sensing (ECIS) analysis. The effect was observed together with a reduction in phospho-FAK and phospho-paxillin in the cells when treated with YZXJ. In the in vivo tumour model, YZXJ was found to significantly inhibit the growth of osteosarcoma with a sustained effect observed when YZXJ was delivered intraperitoneally. YZXJ sensitized cells to the effect of FAK inhibitor in vitro and in vivo. It is concluded that Yangzheng Xiaoji plays a significant role in cell-matrix adhesion and tumour growth, likely by inhibiting the activation of the FAK pathway. The therapeutic role of Yangzheng Xiaoji in osteosarcoma warrants further investigation.

To better understand the impact of undernutrition, nutritional risk, and nutritional treatment on the clinical outcomes of hospitalized cancer patients in China, the authors conducted a multicenter, cross-sectional study with 2248 cancer patients from 20 hospitals from January to June 2010. The authors defined 19.7% and 26.8% patients as undernourished at baseline and reassessment, respectively. Patients with gastrointestinal malignancies had a higher rate of undernutrition than other patients. The nutritional risk rate was 24.6% and 40.2% at baseline and reassessment, respectively. For patients with nutritional risk, the relative risk (RR) of adverse events (AEs) significantly increased with and without nutritional treatment. In comparison with the nonnutritional treatment subgroup, patients who received enteral nutrition (EN) or total parenteral nutrition (TPN) significantly reduced the RR of AE development. The RR of AEs for EN and TPN were 0.08 (95% CI: 0.01-0.62) and 0.56 (95% CI: 0.33-0.96), respectively. Separated nutrient infusion increased the risk of AEs. The authors concluded that undernutrition and nutritional risk are general problems that impact the outcomes of hospitalized cancer patients in China. Higher NRS2002 scores are related to AE risk but not weight loss. In nutritional treatment, EN and TPN can significantly reduce the risk of AEs.

The prognosis for ovarian metastasis of gastric cancer is poor. There is no currently available treatment for this disease. The purpose of this study was to evaluate the efficacy and safety of hyperthermic intraperitoneal chemotherapy (HIPEC) after cytoreductive surgery (CRS) in female gastric cancer patients with metachronous ovarian metastasis. From January 2000 to December 2010, 62 patients developed ovarian metastasis after undergoing gastrectomy with D2 lymphadenectomy. Thirty-two patients underwent CRS plus HIPEC, and 30 patients underwent CRS alone. The median age of all 62 patients was 44 years (range 19-71 years). Metastatic carcinoma involving bilateral ovaries was observed in 50 patients (80.6 %). The median survival time in the CRS + HIPEC group was 15.5 months (95 % confidence interval [CI] 12.1-18.9 months) but was only 10.4 months (95 % CI 8.5-12.2 months) in the CRS group (P = 0.018). Among the 32 patients with pelvic peritoneal metastasis, a stratified analysis revealed that the median survival period for the 15 patients treated with CRS + HIPEC was significantly higher than that for the patients treated with CRS alone (P = 0.046). Among the 30 patients who suffered from ovarian metastasis alone, the median survival times were similar in both groups (P = 0.141). A multivariate analysis revealed that CRS + HIPEC and a low Peritoneal Cancer Index (PCI) were independent predictors for improved survival. In conclusion, our study indicates that employing the HIPEC procedure after CRS could improve the survival time of patients with ovarian metastasis with few complications; however, we do not recommend HIPEC treatment for ovarian metastasis alone.
