OBJECTIVETo 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.

METHODSFifteen 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.

RESULTSEighty-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.

CONCLUSIONSAddition 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.

OBJECTIVETo evaluate the efficacy and safety of weekly paclitaxel combined with S-1 or fluorouracil in the first line treatment of advanced gastric carcinoma.

METHODSTwo hundred and forty patients with untreated advanced gastric carcinoma were randomized into two arms, patients in the experimental arm were given paclitaxel and S-1, while those in the control arm received paclitaxel and fluorouracil. The regimen of experimental arm was paclitaxel 60 mg/m(2) by intravenous infusion, day 1, 8, 15; S-1 80 - 120 mg/day given by oral administration, day 1 - 14. The regimen of control arm was fluorouracil 500 mg/m(2) by intravenous infusion continuously, day 1 - 5; CF 20 mg/m(2) by intravenous infusion, day 1 - 5. The regimens in both arms were repeated every 28 days. The efficacy and safety of both arms were assessed.

RESULTSTwo hundred and twenty-eight patients were analyzed in the full analysis set, and 192 patients were analyzed in per-protocol set (experimental arm 100 patients, control arm 92 patients). The overall response rates of experimental and control arms were 50.0% and 28.3% (P = 0.002), and the disease control rates were 82.0% and 70.7% (P = 0.064), respectively. The primary endpoints of experimental arm were non-inferior to that of the control arm. The secondary endpoint of experimental arm in terms of median progression free survival was significantly better than that of control arm (5 months versus 4 months, P = 0.006). The experimental arm had a higher incidence of grade III-IV bone marrow suppression than the control arm, but the incidence of fever in both arms was not significantly different.

CONCLUSIONSOral administration of S-1 is an alternative option of venous infusional fluorouracil. Weekly paclitaxel combined with S-1 is a safe regimen and has a promising efficacy.

OBJECTIVEThe combination of oxaliplatin and S-1 is effective in patients with advanced gastric cancer. The purpose of this study was to analyze the safety and compliance of this combination regimen as adjuvant chemotherapy in patients with gastric cancer.

METHODSClinical data of 71 patients with gastric cancer treated with oxaliplatin plus S-1 as adjuvant chemotherapy in the Cancer Hospital, Chinese Academy of Medical Sciences (CAMS) from Jan 1(st), 2010 to Jan 1(st), 2012 were retrospectively reviewed. The types and incidence rate of adverse events related to chemotherapy and the results of follow up of the patients were analyzed.

RESULTSAmong the 71 cases, 17 were treated with oxaliplatin biweekly, while 54 with oxaliplatin triweekly. The most common adverse events were neutropenia (n = 49, 69.0%), nausea/vomiting (n = 51, 71.8%), and anorexia (n = 49, 69.0%). The most frequent grade 3-4 toxicities were neutropenia (n = 13, 18.3%), thrombocytopenia (n = 10, 14.1%), anorexia (n = 5, 7.0%) and nausea/vomiting (n = 4, 5.6%). Seven (87.5%) of the 8 patients previously treated with neoadjuvant chemotherapy experienced thrombocytopenia in the postoperative adjuvant chemotherapy, and four (50%) of the 8 patients experienced grade 3-4 thrombocytopenia. The rates of grade 3-4 adverse events in patients aged 65-years or older were similar to that in younger patients.

CONCLUSIONSThe combination of oxaliplatin and S-1 used as adjuvant chemotherapy is well tolerated by patients with gastric cancer. Neutropenia, thrombocytopenia, nausea/vomiting and anorexia are the major treatment-related adverse events. Patients who received neoadjuvant chemotherapy do not well tolerate this regimen as postoperative adjuvant chemotherapy. This combination regimen has a manageable tolerability profile in adjuvant setting in patients ≥ 65 years old.

OBJECTIVETo observe and compare the response rate and toxicity of irinotecan or oxaliplatin combined with capecitabine in the treatment of advanced gastric cancer.

METHODSSixty-three patients with advanced gastric cancer were randomly divided into two groups. The CPT-11 + CAP group consisted of 32 patients who received irinotecan plus capecitabine: CPT-11 100 mg/m(2) was injected in 90 minutes on d 1, 8;capecitabine 2000 mg/m(2), bid, with the first dose in the evening of day 1 and last dose the morning of day 15, repeated for every 21 days. The L-OHP + CAP group consisted of 31 patients who received oxaliplatin plus capecitabine: oxaliplatin 100 mg/m(2) on day 1, capecitabine 2000 mg/m(2), bid, with the first dose in the evening of day 1 and last dose the morning of day 15, repeated for every 21 days. Two or more cycle chemotherapy was completed in each group.

RESULTSIn the CPT-11 + CAP group, no patient achieved complete response and 13 patients achieved partia1 response. The overall response rate was 40.6% (13/32), and the median progression-free survival time was 6.3 months. In the L-OHP + CAP group, no patient achieved complete response and 12 patients achieved partial response. The overall response rate was 38.7% (12/31), and the median progression-free survival time was 6.1 months. There was no significant difference between them (P > 0.05). The most common toxicities were gastrointestinal reaction, peripheral neuropathy and myelosuppression in the two groups. Patients in CPT-11 + CAP group experienced more III/IV diarrhea (28.1%/3.2%, P = 0.018). On the contrary, the rate of III/IV neurotoxicity in the group B was higher (25.8%/3.1%, P = 0.027). No chemotherapy-related death occurred.

CONCLUSIONThe therapeutic effects of irinotecan or oxaliplatin combined with capecitabine in the treatment of advanced gastric cancer are good and comparable, and their toxicities are tolerable.

OBJECTIVETo evaluate the effectiveness and safety of large dose compound Sophora flavescens Ait injection in the treatment of advanced malignant tumors.

METHODSA non-randomized case control trial was conducted. Ninety six patients with pathologically confirmed advanced non-small-cell lung cancer, gastric cancer and colorectal cancer were divided into traditional Chinese medicine group and chemotherapy group, 48 cases each. Patients of the traditional Chinese medicine group received treatment with large dose of compound Sophora flavescens Ait injection (20 ml/d), and 21 days as a cycle.

RESULTSForty-seven patients of the traditional Chinese medicine group and 46 patients of the chemotherapy group completed their treatment, respectively. The clinical benefit rate (CBR) in the traditional Chinese medicine group was 83.0%, significantly higher than that in the chemotherapy group (69.6%) (P < 0.01). The Karnofsky performance status and weight improvement in the traditional Chinese medicine group was superior to that in the chemotherapy group (P < 0.05). Except the skin irritation in one patient in the traditional Chinese medicine group, there were no other clinical adverse effects related with the large dose compound Sophora flavescens Ait injection.

CONCLUSIONSLarge dose compound Sophora flavescens Ait injection in the treatment of advanced malignant tumors is safe and effective. The recommended dose is 20 ml/d.

OBJECTIVETo explore the efficacy, time to disease progression (TTP), overall survival (OS) and toxicity of paclitaxel liposome versus paclitaxel combined with 5-fluorouracil (5-Fu) for patients with advanced gastric cancer.

METHODSThe therapeutic efficacy of chemotherapy with either of the two regimens for 67 cases of naïve advanced gastric cancer was analyzed. Among them, 31 patients in the paclitaxel liposome-5-Fu group received paclitaxel liposome 175 mg/m(2) d1, CF 200 mg/m(2) d1, 5-Fu 2.6 g/m(2) civ. 46 hours, 21 days as one cycle, and 34 patients in the paclitaxel-5-Fu group received paclitaxel 175 mg/m(2) d1, CF 200 mg/m(2) d1, 5-Fu 2.6 g/m(2) civ. 46 hours, 21 days as one cycle.

RESULTSThe objective response rate was 54.8% in the paclitaxel liposome group and 44.1% in the paclitaxel group (P = 0.388). The median time to progression was 5.10 months vs. 5.20 months (P = 0.266) and the median survival time was 10.07 months vs. 8.97 months (P = 0.186). The most frequent side-effects were nausea, vomit and hematological toxicities. The rates of grade III-IV nausea and vomit were 16.1% and 50.0% (P = 0.038), muscle and joint pain were 9.7% and 29.4% (P = 0.047).

CONCLUSIONBoth regimens are effective in the treatment of advanced gastric cancer. However, less adverse effects occur in the paclitaxel liposome group.

Carney triad is a rare syndrome of unknown etiology characterized by having at least two out of three following neoplasms: gastrointestinal stromal tumor, pulmonary chondroma and extra-adrenal paraganglioma. About 100 cases have been reported worldwide. We report a case of Carney triad in a 42-year-old woman presented with a gastrointestinal stromal tumor in the stomach and a malignant functioning paraganglioma in the retroperitoneum that was fatal five years after diagnosis. The gastrointestinal stromal tumor was diagnosed as intermediate-risk of aggressive behavior and diffusely positive for c-kit whereas the retroperitoneal paraganglioma was negative for c-kit. Genetic analyses showed no mutations of KIT, PDGFRA, SDHB, SDHC, and SDHD genes in both tumors. To our best knowledge, this is the first case of Carney triad in Korea.
