- Background: To compare irinotecan with the Nordic 5-fluorouracil (5-FU) and folinic acid (FA) bolus schedule [irinotecan 180 mg/m2 on day 1, 5-FU 500 mg/m2 and FA 60 mg/m2 on day 1 and 2 (FLIRI)] or the Lv5FU2 schedule [irinotecan 180 mg/m2 on day 1, FA 200 mg/m2, 5-FU bolus 400 mg/m2 and infused 5-FU 600 mg/m2 on day 1 and 2 (Lv5FU2-IRI)] due to uncertainties about how to administrate 5-FU with irinotecan. Patients and methods: Patients (n = 567) with metastatic colorectal cancer were randomly assigned to receive FLIRI or Lv5FU2-IRI. Primary end point was progression-free survival (PFS). Results: Patient characteristics were well balanced. PFS did not differ between groups (median 9 months, P = 0.22). Overall survival (OS) was also similar (median 19 months, P = 0.9). Fewer objective responses were seen in the FLIRI group (35% versus 49%, P = 0.001) but the metastatic resection rate did not differ (4% versus 6%, P = 0.3). Grade 3/4 neutropenia (11% versus 5%, P = 0.01) and grade 2 alopecia (18% versus 9%, P = 0.002) were more common in the FLIRI group. The 60-day mortality was 2.4% versus 2.1%. Conclusions: Irinotecan with the bolus Nordic schedule (FLIRI) is a convenient treatment with PFS and OS comparable to irinotecan with the Lv5FU2 schedule. Neutropenia and alopecia are more prevalent, but both regimens are equally well tolerated. © The Author 2008.

Journal article (peer-reviewed)abstract
- Background: The efficacy of oxaliplatin combined with capecitabine (XELOX) as second-line therapy in patients with advanced colorectal cancer (ACRC) resistant to irinotecan is not well established. Oxaliplatin induces acute, cold-induced neuropathy in most patients. The incidence is claimed to be infusion rate-dependent and therefore a 2-h infusion is recommended. Patients and methods: For practical and economic reasons, but also for patient's convenience, we performed a phase II study to examine XELOX30 (capecitabine 1000 mg/m2 orally twice daily on days 1-14 and oxaliplatin 130 mg/m2 as a 30 min infusion on day 1) in patients with ACRC resistant to irinotecan. In addition the pharmacokinetics of oxaliplatin was studied. Results: From November 2002 to September 2003, 70 patients with ACRC were treated with XELOX30. Median age was 62 (range 33-74 years) years and median performance status was 1 (range 0-2). The median number of courses was four (range 1-12) and median cumulative dose of oxaliplatin was 530 (range 125-1560) mg/m2. The response rate was 17% (95% CI 10-23), median time to progression (TTP) was 5.4 months (95% CI 4.6-6.4) and median survival 9.5 months (95% CI 8.5-11.2). White blood cell count (WBC) and performance status were significantly correlated to TTP. Neurotoxicity was moderate: grade 1 56%, grade 2 17% and grade 3 6%. Other grade 3 toxicities were nausea/ vomiting 9%, diarrhoea 14% and PPE 8%. The maximum blood concentration and total body clearance of oxaliplatin was higher than previously reported in studies examining 2-h infusions, but the volume of distribution and terminal half-life was in close agreement with previous results. Conclusion: XELOX30 is a very convenient second-line regimen in ACRC with an activity and safety profile similar to other oxaliplatin schedules. © 2005 European Society for Medical Oncology.

Journal article (peer-reviewed)abstract
- Background: Oxaliplatin in combination with capecitabine prolongs survival in patients with metastatic colorectal cancer (mCRC). Chronomodulation might reduce toxicity and improve efficacy. Patients and methods: A phase II study examining chronomodulated XELOX30 (XELOX30chron): oxaliplatin: 130 mg/m2 on day 1, as a 30-min infusion between 1 and 3 p.m. Capecitabine: total daily dose of 2000 mg/m2, 20% of the dose between 7 and 9 a.m. and 80% of the dose between 6 and 8 p.m. in patients with mCRC resistant to irinotecan. Seventy-one patients were enrolled. Response rate was 18%, median progression-free survival 5.1 months and median overall survival (OS) 10.2 months. Platelet count and performance status were significantly correlated to OS in multivariate analyses. Neurotoxicity grade 2 and 3 was seen in 25% and 2% of patients, respectively, other grade 3 toxic effects were as follows: nausea 6%, vomiting 3%, diarrhoea 12% (3% experienced grade 4) and palmoplantart erytem 9%. Conclusion: XELOX30chron is a convenient second-line regimen with efficacy and safety profile similar to other oxaliplatin schedules. To further investigate chronomodulated XELOX, we have started a Nordic randomised phase II study comparing XELOX30 and XELOX30chron as first-line therapy in patients with mCRC. © The Author 2008.
