Post-operative chemotherapy in non-curative gastrectomy for advanced gastric cancer.

BACKGROUND/AIMS: The definitive effects of post-operative chemotherapy for prolonging survival in patients with non-curative gastrectomy for advanced gastric cancer have not been established. METHODOLOGY: Eighty-three patients with advanced gastric cancer who underwent non-curative gastrectomy were divided into 49 patients with post-operative chemotherapy (chemotherapy group) and 34 patients without post-operative chemotherapy (control group). Chemotherapy regimens were as follows: oral 5-fluorouracil (5-FU) alone (n = 22), intravenous mitomycin (MMC) plus 5-FU (n = 20), intravenous methotrexate (MTX) plus 5-FU (n = 3), intravenous cisplatin plus 5-FU (n = 2), and hepatic arterial infusion of 5-FU plus oral 5-FU (n = 2). No prior chemotherapy or radiation therapy was given. RESULTS: Although the age in the control group (mean: 71.9 years) was significantly older than in the chemotherapy group (mean: 66.1 years), there were no significant differences in the other clinical and pathological background data between the two groups. The 1-year survival rate in the chemotherapy group (71.4%) was significantly higher than in the control group (50.0%). However, the 3-year and 5-year survival rates did not significantly differ in the chemotherapy group versus the control group, 30.6% vs. 32.4% and 24.5% vs. 32.4%, respectively. Although a significant difference did not exist between the two groups, median survival after operation in the chemotherapy group (20.5 months) was longer than that in the control group (16.2 months). Furthermore, median survival of patients with peritoneal dissemination in the chemotherapy group (16.4 months) was significantly longer than that in the control group (7.7 months). CONCLUSIONS: Post-operative chemotherapy may contribute to prolonged survival in patients with non-curable advanced gastric cancer, even when patients had peritoneal dissemination. However, the long-term survival rate was not improved by post-operative chemotherapy. More aggressive chemotherapy may be needed to improve the long-term prognosis for such patients.

The clinical efficacy of adjuvant systemic chemotherapy with gemcitabine in node-positive pancreatic cancer

BACKGROUND/AIMS: The effects of gemcitabine in postoperative adjuvant chemotherapy were evaluated in patients suffering from locally advanced pancreatic cancer with lymph node metastases. The results were compared with those of our historical control patients treated by surgery alone. METHODOLOGY: Twenty-one patients with node-positive pancreatic cancer who had undergone a pancreatic resection with curative intent over the five years up to February 2003, were enrolled in this study. Nine cases received postoperative adjuvant chemotherapy with biweekly administration of 1000 mg/m2 gemcitabine, while the remaining 12 cases underwent surgery without any adjuvant chemotherapy. RESULTS: The chemotherapy was well tolerated with only mild symptomatic and hematologic toxicities. The overall cumulative survival rates of the chemotherapy and surgery-alone groups were 86% and 75% at one year, and 50% and 0% at two years, with a median survival of 20.3 months and 15.4 months, respectively (p=0.0084). The disease-free interval was also significantly greater in the chemotherapy group compared with the surgery-alone group (p=0.0244). CONCLUSIONS: Adjuvant systemic chemotherapy utilizing gemcitabine was feasible with acceptable adverse effects and improved the survival rate of patients with node-positive pancreatic cancer. Although further investigation is needed to confirm these results, gemcitabine is a promising agent for the treatment of resectable advanced pancreatic cancer.     

Intra-arterial continuous infusion for treatment of pancreatic and biliary tract cancer.

BACKGROUND: Systemic chemotherapy does not satisfactorily improve the poor prognosis of pancreas and biliary tract cancer unresectable or metastatic to the liver. Intra-arterial infusion of antineoplastic agents can give higher concentrations to the tumor and slighter concentrations to the whole body, with a potential of efficacy and lower toxicity, due to the hepatic clearance. METHODS: Based on a safe and ambulatorial technique of transcutaneous arterial port implantation, this study was designed to evaluate feasibility and toxicity of 5-fluorouracil (5-FU) intra-arterial continuous infusion combined with systemic gemcitabine with dose escalation. Seventeen patients affected by pancreatic (14) or biliary tract (3) cancer received up to six cycles of treatment. Treatment consisted of intravenous gemcitabine on d 1 and 8 and intra-arterial 5-FU continuous infusion on d 1-14 every 21 d. Dose-escalation levels were 900 and 1000 mg/m2 for gemcitabine and 8, 10, 12, 15, and 17 mg/kg/d for 5-FU. Consecutive cohorts of three patients were planned at each dose level. RESULTS: Gastrointestinal toxicity (vomiting and diarrhea [3rd-4th degree] and gastritis), constituted the dose-limiting toxicity, with a maximum-tolerated dose of 1000 mg/m2 for gemcitabine and 15 mg/kg/d for 5-FU. Hematological toxicity was present in a minority of patients. No patient had acute or later complications such as arterial thrombosis related to the implanted arterial port, sclerosis cholangitis, or chemical cholecistitis. CONCLUSION: 5-Fluorouracil intra-arterial continuous infusion, combined with systemic gemcitabine, seems to be a feasible and safe regimen that could give interesting results in pancreatic cancer.

Phase II Trial of Erlotinib Plus Gemcitabine Chemotherapy in Korean Patients with Advanced Pancreatic Cancer and Prognostic Factors for Chemotherapeutic Response

Background/Aims

Erlotinib and gemcitabine combined chemotherapy is becoming the treatment of choice in advanced pancreatic cancer. We evaluated the effectiveness of treatment with erlotinib plus gemcitabine and the prognostic factors for chemotherapeutic response in Korean pancreatic cancer patients.

Methods

Sixty-nine patients with advanced pancreatic cancer who were treated with daily erlotinib 100 mg orally and gemcitabine 1,000 mg/m²/30 min intravenous infusion on days 1, 8, and 15 of each 4-week cycle from 2006 to 2009 were included in this study. This study was a phase II single-center trial.

Results

All 69 patients with advanced pancreatic cancer were chemotherapy-naïve. The objective response rate was 18.8%, and the overall tumor-stabilization rate was 49.2%. The median overall survival was 7.7 months (95% confidence interval [CI], 6.0 to 9.4 months). The median progression-free survival was 1.9 months (95% CI, 1.4 to 2.5 months). Prognostic factors for good chemotherapeutic response were good performance status and the presence of skin rash during chemotherapy. Patients with lower performance scores showed worse chemotherapeutic responses (odds ratio [OR], 7.6; 95% CI, 2.4 to 24.8). Poor responses were predicted by the absence of skin rash during chemotherapy (OR, 3.0; 95% CI, 1.4 to 6.3).

Conclusions

Erlotinib and gemcitabine chemotherapy is a tolerable treatment regimen and has a favorable therapeutic effect in Korean patients with advanced pancreatic cancer.
