ABSTRACT
Traditional Chinese medicine (TCM) is an important part of the treatment of primary liver cancer (PLC) in China; however, the current instructions for the integrative use of traditional Chinese and Western medicine for PLC are mostly based on expert opinion. There is no evidence-based guideline for clinical practice in this field. Therefore, the Shanghai Association of Chinese Integrative Medicine has established a multidisciplinary working group to develop this guideline, which focuses on the most important questions about the use of TCM during PLC treatment. This guideline was developed following the methodological process recommended by the World Health Organization Handbook for Guideline Development. Two rounds of questionnaire survey were performed to identify clinical questions; published evidence was searched; the Grading of Recommendations Assessment, Development and Evaluation approach was used to evaluate the body of evidence; and recommendations were formulated by combining the quality of evidence, patient preferences and values, and other risk factors. The guideline was written based on the Reporting Items for Practice Guidelines in Healthcare tool. This guideline contains 10 recommendations related to 8 questions, including recommendations for early treatment by TCM after surgery, TCM combined with transcatheter arterial chemoembolization for advanced PLC, TCM drugs for external use, and acupuncture and moxibustion therapy.

<p><b>OBJECTIVE</b>To evaluate the efficacy and safety of trastuzumab in combination with chemotherapy versus chemotherapy alone in the first-line treatment of HER-2-positive advanced gastric or gastro-oesophageal junction cancer.</p><p><b>METHODS</b>Fifteen Chinese research centers are involved in the BO18255 (ToGA) study. Patients with gastric or gastro-oesophageal junction cancer were eligible for inclusion if their tumor showed overexpression of HER-2 protein by immunohistochemistry +++ or FISH-positive. Patients were randomly assigned in a 1:1 ratio to receive a chemotherapy regimen consisting of capecitabine or 5-FU plus cisplatin or chemotherapy in combination with intravenous trastuzumab. The primary endpoint was overall survival.</p><p><b>RESULTS</b>Eighty-five Chinese patients were enrolled in this study, of whom 84 were included in the primary analysis: trastuzumab plus chemotherapy (FP/H) (n = 36) and chemotherapy alone (FP)(n = 48). The median follow-up was 15.2 months in the FP/H group and 14.2 months in the FP group. The median survival time was 12.6 months in the FP/H group compared with 9.7 months in the FP group [hazard ratio 0.72, 95%CI (0.40; 1.29)]. Grade 3/4 adverse events were higher in the FP/H(63.9%)than FP (47.9%) groups, including neutropenia, vomiting and nausea. Two mild cardiac adverse events occurred in the FP/H group. Severe adverse events occurred in 3 cases of both two groups, respectively.</p><p><b>CONCLUSIONS</b>Addition of trastuzumab to chemotherapy is well tolerated and shows improved survival in Chinese patients with advanced gastric or gastro-oesophageal junction cancer. These results are consistent with the results of ToGA whole population trial. Trastuzumab in combination with chemotherapy can be considered as a new option for patients with HER-2-positive advanced gastric or gastro-oesophageal junction cancer.</p>

<p><b>BACKGROUND</b>Three randomised trials have demonstrated that combining bevacizumab with first-line chemotherapy significantly improves progression-free survival versus chemotherapy alone in HER2-negative locally recurrent/metastatic breast cancer (LR/mBC). However, data from Chinese populations are limited and possible differences between ethnic and geographic populations are unknown. This study was conducted to determine whether there are differences in safety and efficacy in patients with HER2-negative LR/mRC between Chinese and Western populations after they receive first-line bevacizumab combined with taxane-based therapy.</p><p><b>METHODS</b>In the single-arm, open-label, Avastin Therapy for Advanced Breast Cancer (ATHENA) study (NCT00448591), patients with HER2-negative LR/mBC received first-line bevacizumab (investigator's choice of 10 mg/kg every 2 weeks or 15 mg/kg every 3 weeks) combined with taxane-based therapy. The primary endpoint was safety profile and the secondary is time to progression (TTP). A subpopulation analysis was conducted to assess safety and efficacy in Chinese patients.</p><p><b>RESULTS</b>Of 2264 patients treated in ATHENA, 202 were enrolled in China. Bevacizumab was combined with docetaxel in 90% of Chinese patients and paclitaxel in 10%. The most common grade 3/4 adverse events were diarrhoea (in 5.0% of patients) and hypertension (in 2.5% of patients). Grade 3/4 proteinuria occurred in 0.5%. After median follow-up of 17.6 months and events in 56% of patients, median TTP was 9.0 months (95%CI, 8.4-11.1). Overall survival data were immature.</p><p><b>CONCLUSIONS</b>We found no evidence of increased bevacizumab-related toxicity or reduced efficacy in Chinese LR/mBC patients receiving first-line bevacizumab-taxane therapy compared with predominantly Western populations. The safety profile was generally similar to previously reported LR/mBC trials. Subtle differences may be attributable to different lifestyle and cardiovascular risk factors in Chinese patients compared with the overall population. It appears reasonable to extrapolate findings from bevacizumab-based randomised trials to Chinese populations.</p>

<p><b>BACKGROUND</b>The high mobility group A1 (HMGA1) proteins are architectural transcription factors found to be overexpressed in lung adenocarcinoma. Lentivirus-mediated RNA interference (RNAi) technology is a powerful tool for silencing endogenous or exogenous genes in human cancer cells. Our preliminary study shows that gemcitabine inhibits growth of the human lung cancer cell line SPCA-1 and induces apoptosis, and this effect might link with down-regulation of HMGA1 expression. This study aimed to investigate the chemosensitivity change of the lung adenocarcinoma cells SPCA-1 after HMGA1 inhibition by lentivirus-mediated RNAi.</p><p><b>METHODS</b>We studied a highly malignant lung adenocarcinoma cell line (SPCA-1 cells). Lentiviral short-hairpin RNA (shHMGA1) expression vectors targeting HMGA1 were used for generation of lentiviral particles. After being transfected into the lung adenocarcinoma cell line SPCA-1, the expression of HMGA1 was determined by retrotranscriptase polymerase chain reaction (RT-PCR) and Western blotting. The effect of gemcitabine on proliferation of positive and negative cells was observed by methyl thiazolyl tetrazolium (MTT) assay and clonogenic survival assay. Apoptosis was observed by flow cytometery. Chemosensitivity to gemcitabine was determined by IC50 analysis. Caspase activity was quantitated by a caspase colorimetric protease assay kit.</p><p><b>RESULTS</b>HMGA1-siRNA silenced its target mRNA specifically and effectively in SPCA-1 cells. The apoptotic rates of the scramble control group were (7.43 ± 0.21)%, (11.00 ± 0.20)%, and (14.93 ± 0.31)%, and the apoptotic rates in the silenced group were (9.53 ± 0.42)%, (16.67 ± 0.45)%, and (25.40 ± 0.79)% under exposure to 0.05, 0.5 and 5.0 µg/ml of gemcitabine (P < 0.05). The IC(50) of the silenced group was (0.309 ± 0.003) µg/ml which was significantly lower than in the scramble control group, (0.653 ± 0.003) µg/ml (P < 0.05). It reduced cancer cell proliferation and increased apoptotic cell death after being treated with gemcitabine compared with the scramble control group. HMGA1 silencing resulted in reduction in the phosphorylation of Akt, and promoted the activation of caspases 3, 8 and 9 upon exposure to gemcitabine.</p><p><b>CONCLUSIONS</b>Lentivirus-mediated RNA interference of HMGA1 enhanced chemosensitivity to gemcitabine in lung adenocarcinoma cells. The mechanism may be associated with the PI-3K/Akt signal pathway. HMGA1 may represent a novel therapeutic target in lung cancer.</p>

<p><b>OBJECTIVE</b>To evaluate the effect and adverse effects of arsenic trioxide (As2O3) in the treatment of primary hepatocarcinoma patients, and conduct the pharmacokinetics study.</p><p><b>METHODS</b>A total of one hundred and eleven advanced primary hepatocarcinoma patients in five centers were treated with As2O3 injection 7 - 8 mg/m(2) i.v. qd for 14 days and was repeated after 7 - 14 days. Evaluation of the clinical response and adverse effects was conducted after two cycles of treatment. The patient who had reached partial PR and SD was treated continuously until disease progression or intolerance.</p><p><b>RESULTS</b>Among the 102 patients evaluable for clinical efficacy analysis, there were 7 PR, 71 SD and 24 PD, the response rate was 6.9% and the clinical benefit rate was 76.5%. The quality of life was improved in 22.5% of patients. The pain relief rate was 71.7%, time to progress (TTP) was 97 days, and the median survival time (MST) was 195 days. The major adverse effects were reversible WHO I-II grade gastrointestinal reactions and bone marrow suppression. The results of pharmacokinetic study showed that the distribution and elimination characteristics in vivo was found to be a two-compartment model. The plasma elimination half-life was (23.94 ± 18.39) h.</p><p><b>CONCLUSIONS</b>As2O3 is effective in the management of primary hepatocarcinoma, with a significant analgesic effect. To some extent, it can extend TTP and MST in advanced liver cancer patients, while the treatment is well tolerated in the majority of patients.</p>

The efficacy and safety of bevacizumab with modified irinotecan, leucovorin bolus, and 5-fluorouracil intravenous infusion (mIFL) in the first-line treatment of metastatic colorectal cancer (mCRC) has not been well evaluated in randomized clinical trials in Chinese patients. We conducted a phrase III trial in which patients with previously untreated mCRC were randomized 2:1 to the mIFL [irinotecan (125 mg/m(2)), leucovorin (20 mg/m(2)) bolus, and 5-fluorouracil intravenous infusion (500 mg/m(2)) weekly for four weeks every six weeks] plus bevacizumab (5 mg/kg every two weeks) group and the mIFL group, respectively. Co-primary objectives were progression-free survival (PFS) and 6-month PFS rate. In total, 214 patients were enrolled. Our results showed that addition of bevacizumab to mIFL significantly improved median PFS (4.2 months in the mIFL group vs. 8.3 months in the bevacizumab plus mIFL group, P < 0.001), 6-month PFS rate (25.0% vs. 62.6%, P < 0.001), median overall survival (13.4 months vs. 18.7 months, P = 0.014), and response rate (17% vs. 35%, P = 0.013). Grades 3 and 4 adverse events included diarrhea (21% in the mIFL group and 26% in the bevacizumab plus mIFL group) and neutropenia (19% in the mIFL group and 33% in the bevacizumab plus mIFL group). No wound-healing complications or congestive heart failure occurred. Our results suggested that bevacizumab plus mIFL is effective and well tolerated as first-line treatment for Chinese patients with mCRC. Clinical benefit and safety profiles were consistent with those observed in pivotal phase III trials with mainly Caucasian patients.

<p><b>OBJECTIVE</b>To study the anti-angiogenesis effect and toxicity of arsenic trioxide (As2O3) plus cinobufacin on transplanted human hepatocarcinoma in nude mice, and the acting mechanism of the treatment was explored as well.</p><p><b>METHODS</b>Human hepatocarcinoma was transplanted in nude mouse, and the modeled mice were divided at random into 4 groups, 8 in each group. They were treated respectively with normal saline (GA), 2.5 mg/kg As2O3 (GB), 5 mL/kg cinobufacin (GC) and 2.5 mg/kg As2O3 + 5 mL/kg cinobufacin (GD), by intraperitoneal injection for 21 days. The anti-tumor effects was evaluated by estimating general condition of nude mice, tumor size, microvessel density(MVD) level. Expressions of vascular endothelial growth factor (VEGF) and epidermal growth factor receptor (EGFR) in tumor, in tumor tissue of mice as well as pathology of tumor were detected by immunohistochemistry assay, optical microscope, transmission electron microscope (TEM), respectively. Moreover, blood routine and pathological examinations of liver and kidney were performed.</p><p><b>RESULTS</b>The tumor weight and volume were 0.65 +/- 0.25 g and 0.44 +/- 0.14 cm3 in GB, 0.70 +/- 0.27 g and 0.46 +/- 0.19 cm3 in GC, 0.42 +/- 0.16 g and 0.26 +/- 0.11 cm3 in GD, all significantly lower than those in GA (1.06 +/- 0.25 g and 0.67 +/- 0.17 cm3, P < 0.05). The coefficient of drug interaction (CDI) on tumor weight was 0.97 and that on tumor size was 0.86, all less than 1, showing the synergistic action between the two drugs. Expressions of VEGF and EGFR in tumor as well as the MVD were decreased in GB and GC, and the decreasing of these indices were even more significant in GD. Pathologic examination showed the growth of tumor in GB, GC and GD were all inhibited significantly. No obvious toxicity of the treatments to the hepatic, renal and hematopoietic systems in the nude mice was observed.</p><p><b>CONCLUSIONS</b>As2O3 and cinobufacini showed synergistic action in inhibiting human hepatocarcinoma in nude mice and the angiogenesis in tumor. Combined use of the two had no obvious toxicity to the hepatic, renal and hematopoietic systems.</p>

<p><b>OBJECTIVE</b>To investigate the effect of endostar in controlling ascites tumor formation in mice.</p><p><b>METHODS</b>Mouse models bearing ascites tumors were established via intraperitoneal injection of H22 and S180 cell lines. Eighty-eight ICR mice were randomly assigned into 4 groups, namely the control group (0.9% normal saline) and 3 endostar groups with 8 mg/kg endostar administration daily, every other day or every two days. The peritoneal membrane permeability of the mice was assessed using Evan blue staining. The body weight curve of mice was drawn, and the cumulative ascites volume and number of red cells and tumor cells in the malignant ascites were determined. The survival of the mice was evaluated to assess the therapeutic effect of endostar.</p><p><b>RESULTS</b>Compared with the control group, the mice receiving daily endostar injection showed obviously lower ascites accumulation and peritoneal capillary permeability (P<0.05) with reduced count of ascites tumor cells and red cells and tumor burden of the abdominal cavity. The mice with daily endostar injection also showed longer survival than the control group.</p><p><b>CONCLUSIONS</b>Continuous intraperitoneal injection can be the optimal means for endostar administration for treatment of malignant ascites.</p>

<p><b>BACKGROUND</b>Platinum-based chemotherapeutics are the most common regimens for advanced non-small-cell lung cancer (NSCLC) patients, and genetic factors are thought to represent important determinants of drug efficacy. We prospectively assessed the status of the XPC Ala499Val and Lys939Gln gene polymorphisms and investigated whether these SNPs can predict the response to cisplatin/carboplatin-based regimens in advanced NSCLC patients in a Chinese population.</p><p><b>METHODS</b>The treatment outcomes of 96 advanced NSCLC patients who were treated with platinum-based chemotherapy were evaluated. The polymorphic status of xeroderma pigmentosum group C (XPC) gene was genotyped by the 3-D polyacrylamide gel-based DNA microarray method.</p><p><b>RESULTS</b>The distributions of XPC Lys939Gln genotypes differed significantly between the response group (complete + partial responses) and the non-response group (stable + progressive disease; P = 0.022). The heterozygous A/C genotype carriers had a poorer response rate than the wild A/A genotype carriers in stage III (OR, 0.074; 95%CI, 0.008 - 0.704; P = 0.023). The XPC Ala499Val polymorphisms were not associated with response to platinum-based chemotherapy.</p><p><b>CONCLUSION</b>Polymorphisms of the XPC gene, Lys939Gln, may be a predictive marker of treatment response for advanced NSCLC patients in stage III.</p>
