OBJECTIVETo explore the feasibility, safety and efficacy of intraoperative regional infusion chemotherapy by celiac trunk in advanced gastric cancer patients.

METHODSOne hundred and twenty-six patients with advanced gastric cancer(stageII(-III() were screened from database of Gastrointestinal Surgery Department of Taizhou People's Hospital between January 2008 and December 2010 who underwent R0 resection and D2 lymphadenectomy, received postoperative chemotherapy(XELOX or FOLFOX), and had complete follow-up data. They were divided into infusion chemotherapy group (65 cases) and control group (61 cases) according to regional infusion chemotherapy or not (fluorine 1 000 mg and cisplatin 60 mg). The side effects of chemotherapy, parameters related to the operation, long-term survival and relapse rate were compared between the two groups.

RESULTSThe baseline data between the two groups were comparable(all P>0.05). Postoperative III( and IIII( adverse reaction of chemotherapy was not significantly different between the two groups (P>0.05). The time of postoperative intestinal function recovery [(67.9±14.8) hours vs. (68.9±15.0) hours, t=-0.380, P=0.705), volume of postoperative 1-week drainage [(66.1±17.1) ml vs.(61.9±18.2) ml, t=1.478, P=0.142], recent morbidity of complications[55.4%(36/65) vs. 49.2%(30/61), χ=0.256, P=0.613], and the long-term morbidity of complications [16.9% (11/65) vs. 14.8% (9/61), χ=0.111, P=0.739] were all not significantly different between the two groups. The 3-year survival rate and 3-year relapse-free survival rate in infusion chemotherapy group were significantly higher than those in control group(58.4% vs. 37.7%, χ=5.382, P=0.020; 58.4% vs. 34.4%, χ=6.636, P=0.010).

CONCLUSIONRegional infusion chemotherapy by celiac trunk during operation for advanced gastric cancer patients is safe and feasible, and can reduce the risk of local recurrence and improve survival rate.

The role of neoadjuvant chemoradiation therapy in locally advanced pancreatic cancer (LAPC) is still controversial. The aim of this study was to evaluate surgical downstaging after concurrent chemoradiation therapy (CCRT) for LAPC by measuring the objective changes after treatment. From January 2003 through July 2011, 54 patients with LAPC underwent neoadjuvant CCRT. Computed tomography findings of the tumor size, including major vessel invasion, were analyzed before and after CCRT. Among the total recruited patients, 14 had borderline resectable malignancy and another 40 were unresectable before CCRT. After CCRT, a partial response was achieved in four patients. Stable disease and further disease progression were achieved in 36 and 14 patients, respectively. Tumor size showed no significant difference before and after CCRT (3.6 +/- 1.1 vs. 3.6 +/- 1.0 cm, P = 0.61). Vessel invasion showed improvement in two patients, while 13 other patients showed further tumor progression. Thirty-nine patients with unresectable malignancy and 11 patients with borderline resectable malignancy at time of initial diagnosis remained unchanged after CCRT. Four patients with borderline pancreatic malignancy progressed to an unresectable stage, whereas one unresectable pancreatic malignancy improved to a borderline resectable stage. Only one patient with borderline resectable disease underwent operation after CCRT; however, curative resection failed due to celiac artery invasion and peritoneal seeding. The adverse events associated with CCRT were tolerable. In conclusion, preoperative CCRT in LAPC rarely leads to surgical downstaging, and it could lower resectability rates.

OBJECTIVETo evaluate the efficacy and safety of gemcitabine combined with ifosfamide (GI regimen)in patients with recurrent or metastatic nasopharyngeal carcinoma after failure of platinum-based chemotherapy.

METHODSThe clinical data of 27 nasopharyngeal carcinoma patients, who received GI regimen between April 2005 and March 2014 after failure of prior platinum-based chemotherapy, were retrospectively reviewed,and relevant prognostic factors were explored.

RESULTSAll patients were evaluable for efficacy and toxicity. No patient achieved complete response (CR). Partial response (PR) was achieved in ten patients, stable disease (SD) in thirteen patients, progressive disease (PD) in four patients, with a response rate of 37.0% and an overall disease control rate (PR+SD) of 85.2%. For ten PR patients, the median duration of response was 5.5 months. The median progression-free survival of the whole group was 6.7 months, and the Kaplan-Meier estimate of median overall survival was 17.4 months. The 1-year survival rate was 72.6%. Toxicity was mainly hematological: Grade III or IV anemia, neutropenia and thrombocytopenia were found in 3.7%, 37.0% and 18.5% of all patients, respectively. Univariate and multivariate analyses indicated that dose intensity of gemcitabine was a significant prognostic factor for PFS, whereas salvage treatment after failure of GI regimen was a significant prognostic factor for OS.

CONCLUSIONSGemcitabine and ifosfamide combination is effective and well tolerated by patients with advanced nasopharyngeal carcinoma pretreated with platinum-based chemotherapy. Further clinical study is warranted.

OBJECTIVETo evaluate the safety and efficacy of gemcitabine combined with S-1 in the treatment of advanced pancreatic cancer.

METHODSA retrospective analysis of the clinical data of 49 patients with advanced pancreatic cancer, who did not receive radiotherapy and chemotherapy, were divided into two groups: the study group (25 cases), and control group (24 cases). Patients in the study group received gemcitabine 1 000 mg/m² via intravenous drip at the first and 8th days, and received S-1 80 mg/m², morning and evening (twice a day) for the first 14 days, and 21 days as a treatment cycle of chemotherapy.The control group was given GEMOX regimen: Gemcitabine 1 000 mg/m² via intravenous drip at the first and 8 days, and oxaliplatin 130 mg/m² via intravenous drip at the first day, and 21 d for a treatment cycle of chemotherapy. The efficacy and adverse reactions in patients of the study and control groups were observed and compared.

RESULTSThe efficiency of the study group was 32.0% and disease control rate was 72.0%. The efficiency of the control group was 25.0% and disease control rate was 58.3%. The differences between the two groups were statistically not significant (P > 0.05 for all). The clinical benefit rate in the study group and control group were 80.0% and 50.0%, respectively, showing a significant difference (P < 0.05). The median survival time was 9.7 months in patients of the study group and 9.0 months in the control group, with a significant difference (P < 0.05). The drug toxicity was well tolerated in both groups, and no chemotherapy-related death occurred. The major adverse reactions were myelosuppression and digestive tract reactions, and the adverse reactions in the study group were lower than those in the control group.

CONCLUSIONSGemcitabine combined with S-1 is effective and safe in the treatment of advanced pancreatic cancer, with less side effects, and can be tolerated by the patients.

Hemolytic uremic syndrome (HUS) is a rare thrombotic complication characterized by a triad of microangiopathic hemolytic anemia, thrombocytopenia, and acute renal failure. HUS may be caused by several different conditions, including infection, malignancy, and chemotherapeutic agents, such as mitomycin, cisplatin, and most recently, gemcitabine. The outcome of gemcitabine-induced HUS is poor, and the disease has a high mortality rate. This study reports a case of gemcitabine-induced HUS in a patient with pancreatic cancer in Korea.

OBJECTIVETo evaluate the efficacy and safety of gemcitabine combined with oxaliplatin (GEMOX) in lymphoma patients after failure of multiple chemotherapy regimens.

METHODSThe clinical data of 27 lymphoma patients, who received GEMOX regimen after failure of two or more prior chemotherapy regimens, were retrospectively reviewed. The predictive factors related to the clinical efficacy of GEMOX regimen were explored.

RESULTSThe efficacy could be evaluated in 24 patients. Complete response was obtained in 4 patients (16.7%), partial response in 7 patients (29.1%), stable disease in 6 patients (25.0%), and progressive disease in 7 patients (29.1%), with an overall response rate of 45.8%. Among the eleven CR and PR patients, four patients were with diffuse large B cell lymphoma, four patients with Hodgkin's lymphoma, one with peripheral T cell lymphoma, one with mantle cell lymphoma and one with gastric mucosa-associated lymphoid tissue lymphoma. The median PFS time of the whole group was 8 months (95%CI, 1.6-14.4 months). For 11 CR and PR patients who had response to the GEMOX regimen, the median PFS time was 19 months (95%CI, 11.1-26.8 months). Major adverse response was hematologic toxicity. Among them, grade III or IV neutropenia appeared in 16 patients (59.3%), and grade III or IV thrombocytopenia appeared in 11 patients (40.7%). The sensitivity to the last chemotherapy was related to the efficacy of GEMOX regimen. The response rate was 83.3% in patients who had response to the last chemotherapy, and only 31.2% in the patients who failed to the last chemotherapy (P = 0.001).

CONCLUSIONSGEMOX regimen can get a better response rate in lymphoma patients after failure of multiple chemotherapy regimens, and with a good tolerance and acceptable safety. Some patients can get long-term survival. Patients sensitive to the last chemotherapy are more likely to benefit from GEMOX regimen.

OBJECTIVEThe aim of this study was to analyze the clinical characteristics, treatment and prognosis of advanced urothelial carcinoma of the bladder (AUCB).

METHODSThe clinicopathological data of 117 patients with AUCB admitted in our hospital from 1998 to 2009 were reviewed. All patients received first-line chemotherapy. The survival rate was calculated by Kaplan-Meier analysis and log-rank test.

RESULTSThe median age of all patients was 56 years and the male-to-female ratio was 3.33:1. Their 6-, 12-, 24-, 36- and 60-month survival rates were 90.3%, 61.3%, 32.3%, 24.2% and 8.1%, respectively. In the first-line chemotherapy regimen, the effectiveness rate of gemcitabine + platinum drugs was 49.3% (37/75), the median progression-free survival(PFS) was 7.9 months and overall survival (OS) was 18.7 months. The effectiveness of cyclophosphamide + epirubicin + platinum drug regimen was 45.5% (10/22), Median PFS was 7.1 months and OS was 15.3 months. The effectiveness of paclitaxel + platinum drug regimen was 47.1% (8/17), median PFS was 6.5 months and OS was 13.7 months. Among them, the effectiveness rate of the gemcitabine + cisplatin regimen in 67 patients was 47.8%, the median PFS was 7.0 months and OS was 15.3 months. In the 13 patients who received paclitaxel + carboplatin regimen, the effectiveness rate was 53.8%, median PFS was 7.7 months and OS was 16.0 months. The major side effects were leucopenia and thrombocytopenia, mostly were tolerable, of grade I to II.

CONCLUSIONSIn advanced unresectable and metastatic urothelial carcinoma of the bladder, GC regimen is recognized as a standard first-line chemotherapy, with a higher effectiveness and tolerable side effects. Taxane and molecular targeted drugs may further improve the therapeutic effect of the treatment of advanced urothelial carcinomas of the bladder in the future.

BACKGROUNDThe aim of this research was to investigate the impact of post-transplantation adjuvant chemotherapy in the prevention of tumor recurrence and metastasis for hepatocellular carcinoma (HCC) exceeding Milan criteria after liver transplantation.

METHODSA total of 117 patients with HCC exceeding the Milan criteria who had undergone orthotopic liver transplantation (OLT) from August 2002 to February 2009 were enrolled and retrospectively analyzed. The patients were divided into four groups according to chemotherapy regimens and the impact of different chemotherapy regimens on survival, disease-free survival, and adverse effects were compared.

RESULTSOne year survival rates for the gemicitabine, conventional chemotherapy, oxaliplatin plus capecitabine and the best supportive care (BSC) group were 87.5%, 84.2%, 81.6%, and 67.5%. The 3-year survival rates were 48.1%, 25.9%, 31.6%, and 33.7%, respectively for the four groups. One year disease free survival rates for the four groups were 69.8%, 47.4%, 53.8%, and 45.7% respectively. And 3-year disease free survival rates were 43.2%, 23.7%, 23.6%, and 25.1% for the four groups. Stratification analysis showed that the gemcitabine regimen and conventional chemotherapy could significantly improve the survival rate and disease free survival rate for HCC patients who had major vascular invasion and/or microvascular invasion after liver transplantation compared with BSC group.

CONCLUSIONSFor HCC patients beyond Milan criteria, especially who had vascular invasion and/or micorvascular invasion, post-transplantation adjuvant chemotherapy can significantly improve survival. Gemcitabine is a proper regimen for postoperative adjuvant chemotherapy. Conventional chemotherapy can also benefit patients, but the adverse effects are not satisfactory.

OBJECTIVEThis study investigates the efficacy and tolerability of capecitabine plus thalidomide in patients with advanced pancreatic cancer who previously underwent gemcitabine-based therapy.

METHODSSixty-one patients with unresectable or metastatic PC who had progressed on single-agent Gem or a Gem-containing regimen were enrolled. The patients were randomly divided into two groups. One group (31 patients) was treated with capecitabine alone, and another group was treated with capecitabine plus thalidomide. Capecitabine was administered orally twice a day at a dose of 1, 250 mg/m(2) for 14-day followed by 7-day rest and oral thalidomide 100 mg was given daily without interruption until disease progression or occurrence of unacceptable toxicity.

RESULTSThe PFS was 2.8 months (95%CI 2.4 - 3.2) vs. 3.1 months (95%CI 2.6-3.6, P < 0.05) and the OS was 6.1 months (95%CI 5.3 - 6.9) vs. 6.3 months (95%CI 5.2 - 7.4, P = 0.426). In the capecitabine alone group, one patient experienced a partial response (PR), 10 patients showed stable disease (SD) and 20 patients had progressive disease (PD). The another group, two patients experienced a partial response (PR), 11 patients SD, and 17 patients PD. The disease control rates were 35.5% and 43.3%, respectively. The major adverse reaction in the two groups was grade 3 diarrhea.

CONCLUSIONCapecitabine plus thalidomide regimen is marginally effective and well tolerated in the second-line setting in patients with gemcitabine-refractory advanced pancreatic cancer.

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.
