Final results of a randomized clinical trial of adjuvant intraportal chemotherapy for colorectal cancer: Intraportal Chemotherapy for Colorectal Cancer Group

The purpose of the present multi-center collaborative study was to elucidate the efficacy of intraportal chemotherapy with the combination of 5-FU and MMC for the prevention of liver recurrence after resection for colorectal cancer. A total of 125 patients with Stage II, III, and IV colorectal cancer were enrolled in this study between June 1993 and December 1995. Of them, 45 patients were randomized to a portal group: 10 mg/body of mitomycin one shot portal infusion, before and after 500 mg/m2 of 5-FU per 24 h for 7 days portal infusion followed by administration of oral 5-FU. Fifty-three patients were randomized to a control group: oral administration of 5-FU. Twelve patients suffered from temporary mild liver damage. One patient (2%) in the portal group and 6 patients (11%) in the control group developed liver metastases; there was not a significant difference between these two groups regarding development of liver metastases. There was also no significant difference by tumor stage between the portal and control groups regarding development of liver metastases. The 5-year survival rate and 5-year disease-free survival were 84.3% and 81.9%, respectively, in the portal group, and 70.7% and 72.4%, respectively, in the control group; the difference was not significant. Although there was not a significant difference between the portal and control groups regarding the prognosis in stage II, there was a significant difference between the portal and control groups regarding the 5-year disease free survival in stage III (81.1% vs 54.2%). These results suggest that intraportal chemotherapy is effective for stage III colorectal cancer.

局部进展期胃癌术前化疗与术前放化疗的对比研究

背景与目的：术前化疗和术前放化疗都是胃癌治疗指南推荐的针对局部进展期胃癌患者的治疗方法。然而,由于缺乏对比性的研究证据,两者的优劣性不详。本研究将对比术前放化疗与术前化疗在临床疗效及毒性反应之间的差异。方法：2007年6月—2012年10月期间,30例局部进展期胃癌患者入组一项术前化疗的Ⅱ期临床试验,采用EOF（表柔比星+奥沙利铂+氟尿嘧啶）方案进行3~4个周期的术前化疗,对于能手术的患者予以手术,术后给于2~3个周期的EOF方案化疗。2012年4月—2014年8月,40例局部晚期胃癌患者入组一项术前放化疗的Ⅱ期临床试验,患者接受1个周期的SOX［替吉奥（S-1）+奥沙利铂］方案化疗,继续行同步放化疗,再进行1个周期的SOX方案化疗,对于能手术的患者予以手术,术后给于4个周期的SOX方案化疗。比较两项临床试验患者的临床病理特点、术前治疗的效果、R0手术切除率、预后及不良反应。结果：术前化疗临床试验定义为化疗组,有30例胃癌患者入组,且完成了所有的术前化疗,都可评估。术前放化疗临床试验定义为放化疗组,有40例胃癌患者入组,其中36例（90%）患者可评估。两组间的基线参数,如性别、年龄、美国东部肿瘤协作组（Eastern Cooperative Oncology Group,ECOG）评分、临床T分期、临床N分期及肿瘤部位,差异无统计学意义。化疗组的临床有效率（CR+PR）为30%（9/30）,放化疗组的临床有效率（CR+PR）为41.7%,两者间的差异无统计学意义（P>0.05）。化疗组与放化疗组间的R0手术切除率差异无统计学意义（46.7% vs 66.7%）。放化疗组的病理有效率高于化疗组,且差异有统计学意义（50.0% vs 23.3%）。术前放化疗组的毒性反应较化疗组明显。放化疗组的3年总生存率为41%,高于化疗组的20% （P=0.009）。结论：放化疗组的病理有效率及3年总生存率高于化疗组。急性毒性反应也较化疗组明显,但无严重的毒性反应。     

Is portal infusion chemotherapy uneffective for hepatic recurrence after resection for colorectal cancer?

Sixty-six patients with colorectal cancer were studied regarding effects of prevention of hepatic recurrence in completely performed portal infusion chemotherapy. The regimen was continuous administration of 500-875 mg/body of 5-FU for 7 days and intraportal administration of 10 mg of MMC before and after 5-FU administration. Hepatic recurrence rate was 7.6% and the five year survival rate was 83.3% in portal infusion group, and 16% and 71.3% in the control group; the difference was not significant. However, the hepatic recurrence rate in patients administered more than 4 g of 5-FU was 2.5%; there was a significant difference between the portal group and control group. The five-year survival rate for patients administered more than 4 g of 5-FU was 92.3%, which was significantly higher than at less than 4 g. Excellent effects for prevention of hepatic recurrence and prognosis were obtained in patients administered more than 4 g of 5-FU. Thus, the compliance of 5-FU in portal infusion chemotherapy is important. Also, administration of MMC is suspected to enhance the effect of portal infusion chemotherapy.     

Randomized controlled trial of the efficacy of adjuvant immunochemotherapy and adjuvant chemotherapy for colorectal cancer, using different combinations of the intracutaneous streptococcal preparation OK-432 and the oral pyrimidines 1-hexylcarbamoyl-5-fluorouracil and uracil/tegafur

Background We investigated the efficacy and safety of adjuvant immunochemotherapy and adjuvant chemotherapy for colorectal cancer, using different combinations of the intracutaneous streptococcal preparation OK-432 and the oral pyrimidines 1-hexylcarbamoyl-5-fluorouracil (carmofur, HCFU) and uracil/tegafur (UFT).Methods Patients with stage II, III, or IV (Dukes B, C) colorectal cancer were enrolled and randomly assigned to one of three groups: an immunochemotherapy group (mitomycin C [MMC] + 5-fluorouracil [5-FU] + HCFU + OK-432), a chemotherapy group (MMC + 5-FU + HCFU), and a control group (surgery alone) for those with colon cancer (study 1); and an immunochemotherapy group (MMC + 5-FU + UFT + OK-432), a chemotherapy group (MMC + 5-FU + UFT), and a control group (surgery alone) for those with rectal cancer (study 2).Results A total of 760 patients with colon cancer and 669 patients with rectal cancer were entered into this randomized clinical trial (RCT). The incidence of side-effects was in the order of: immunochemotherapy group chemotherapy group control group in both the cohort of patients with colon cancer and the cohort with rectal cancer. In particular, the frequency of leucopenia and skin disorders was significantly higher than control groups. There were no severe adverse events such as death related to the adjuvant therapy. In both the colon cancer and rectal cancer cohorts, no significant difference in the 5-year survival rate and disease-free survival rate was noted among the three groups.Conclusion The results of an RCT demonstrated that the combination of MMC + 5-FU + HCFU + OK-432 for colon cancer and that of MMC + 5-FU + UFT + OK-432 for rectal cancer could not prolong the survival of patients with surgically resected colorectal cancer, but that both combinations were well tolerated as adjuvant therapy.

Validity of two-hour continuous hepatic arterial infusion chemotherapy with low-dose 5-FU for unresectable liver metastasis from colorectal cancer

The significance of hepatic arterial infusion chemotherapy for unresectable liver metastases from colorectal cancer was evaluated in 50 patients, who received either of the following regimens: 1 shot 5-FU + epirubicin + MMC (FAM group); hepatic arterial infusion of 5-FU for 2 hours + MMC (MF group); hepatic arterial infusion of 5-FU for 2 hours (5-FU group). There were no differences in the clinicopathological backgrounds of the patients among the groups. The mean survival time was 10.3 months, 16.0 months and 16.2 months in the FAM, MF and 5-FU groups. The effective percentages were 0%, 40% and 31% in the FAM, MF and 5-FU groups and the survival time of the effective cases was 18.1 months and 21.8 months in the MF and 5-FU groups. The MF group and 5-FU group showed significant improvement in prognosis. Concerning side effects, myelo-suppression and gastrointestinal toxicity appeared frequently in the MF group. In conclusion, 2-hour continuous hepatic arterial infusion with low-dose 5-FU for unresectable liver metastases from colorectal cancer may be helpful for improvement of prognosis.     

Clinical observation of XELOX (Capecitabine puls Oxaliplatin): an adjuvant chemotherapy regimen used in stage III colorectal cancer

OBJECTIVE: To evaluate the efficacy and safety of an adjuvant chemotherapy regimen: XELOX (Capecitabine puls Oxaliplatin) used after curative resection for stage III colorectal cancer. METHODS: From Jan. 1998 to Jan. 2004, 256 cases with stage III colorectal cancer randomized received de Gramont, modified FOLFOX4 (mFOLFOX4) and XELOX regimens. The 3-year disease-free survival (DFS) and overall survival (OS) were compared within the three groups and relative prognosis factors within mFOLFOX4 and XELOX groups. Therapeutic adverse events were recorded and analyzed with Kaplan-Meier test. RESULTS: 98, 87 and 71 cases were respectively enrolled in the de Gramont, mFOLFOX4 and XELOX groups, mFOLFOX4 and XELOX had superior efficacy compared with de Gramont regimen. The two former could significantly improve 3-year DFS (79.7% vs. 66.2%, P = 0.015; 81.5% vs. 66.2%, P = 0.004) and medium survival time (40.2 mon vs. 37.8 mon, P = 0.024; 41.4 mon vs. 37.8 mon, P = 0.014). Meanwhile they could respectively decrease the ratio of recurrence risk by 18.0% (P = 0.024) and 21.0% (P = 0.003). The relative benefit of mFOLFOX4 versus XELOX didn't differ for 3-year DFS [hazard ratio (HR): 0.84, 95% confidence interval (CI): 0.79-1.12, P = 0.13] and OS (HR: 0.87, 95% CI: 0.84-1.06, P = 0.54). In the analysis of DFS in relative prognosis factors, XELOX had a better trend of survival advantage. mFOLFOX4 had higher adverse events within these regimens, especially in grade 3 or 4 neutropenia and peripheral neurologic adverse events. CONCLUSION: XELOX maintains its efficacy and safety ratio in advanced colorectal cancer. Patients have good tolerance and compliance. The regiment is deserves to be applied in clinical treatment.
