A phase II trial of gemcitabine and weekly high-dose 5-fluorouracil in a 48-hour continuous-infusion schedule in patients with advanced pancreatic carcinoma. A study of the Spanish Cooperative Group for Gastrointestinal Tumour Therapy (TTD).

AIM: A multi-centred, open-labelled, phase 11 study containing 46 patients was conducted to evaluate the clinical benefit of gemcitabine (1,400 mg/m(2)) combined with 5-FU (3 g/m(2)) in a 48 h continuous infusion (CI). METHODS: Both drugs were administered on days 1, 8 and 15 of every 4 week cycle in chemotherapy-naïve patients with locally advanced unresectable metastatic pancreatic carcinoma. The minimum follow-up was 6 months. RESULTS: Clinical benefit response was the primary endpoint and this was achieved by 24.4% of the patients. Quality of life (QoL) improved in 16.6% of patients. Objective response was observed in 7% of the patients. The median progression-free survival (PFS) was 14.4 weeks and the median overall survival (OS) time was 22.7 weeks. One-year survival was 25%. The most frequent grade 3-4 toxicities were neutropenia (45%), mucositis (7.5%) and hyperbilirubinaemia (10.5%). CONCLUSIONS: This schedule was not superior in terms of clinical benefit, response rate, PFS and OS than standard gemcitabine treatment

Incidence of hand-foot syndrome with capecitabine in combination with chemotherapy as first-line treatment in patients with advanced and/or metastatic gastric cancer suitable for treatment with a fluoropyrimidine-based regimen.

INTRODUCTION: Hand-foot syndrome (HFS) is a limiting toxicity of capecitabine, which is not life-threatening but could compromise capecitabine efficacy. MATERIALS AND METHODS: This phase II, multicenter, non-controlled study assessed the safety, particularly grade three HFS incidence, and efficacy of four capecitabine-based chemotherapy regimens [cisplatin/capecitabine (CX), epirubicin/cisplatin/capecitabine (ECX), epirubicin/oxaliplatin/capecitabine (EOX) and docetaxel/cisplatin/capecitabine (DCX)] as first-line treatment for advanced and/or metastatic gastric cancer. RESULTS: One hundred and eight patients were assigned to one of the four treatment groups, according to investigator's criteria, and grouped together for both safety and efficacy primary analyses. HFS was reported in 31 patients (19.6%) and its first presentation occurred at a median of 72 days (range 19-209 days). Grade 3 HFS developed in 6.3, 5.2, 3.7 and 2.4%, of patients receiving ECX, DCX, EOX or CX chemotherapy regimen, respectively. Capecitabine dose reduction/discontinuation due to HFS was required in 5.7% of patients (9/158). The most common (> 10%) grade 3-4 treatment-related AEs were neutropenia (15.2%), asthenia (12.0%) and diarrhoea (11.4%). CONCLUSIONS: A moderate incidence of HFS was reported in patients treated with capecitabine, which generally presented late and required dose reduction in < 1/3 of patients. The results suggest that capecitabine may be useful in combination with standard fluorouracil-based regimens in patients with advanced and/or metastatic gastric cancer with favourable safety profile.
