- 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.

Tidskriftsartikel (refereegranskat)abstract
- We report on a detailed abundance analysis of two strongly r-process enhanced, very metal-poor stars newly discovered in the HERES project, CS 29491-069 ([Fe/H] = -2.51, [r/Fe] = +1.1) and HE 1219-0312 ([Fe/H] = -2.96, [r/Fe] = +1.5). The analysis is based on high-quality VLT/UVES spectra and MARCS model atmospheres. We detect lines of 15 heavy elements in the spectrum of CS 29491-069, and 18 in HE 1219-0312; in both cases including the Th II 4019 angstrom line. The heavy-element abundance patterns of these two stars are mostly well-matched to scaled solar residual abundances not formed by the s-process. We also compare the observed pattern with recent high-entropy wind (HEW) calculations, which assume core-collapse supernovae of massive stars as the astrophysical environment for the r-process, and find good agreement for most lanthanides. The abundance ratios of the lighter elements strontium, yttrium, and zirconium, which are presumably not formed by the main r-process, are reproduced well by the model. Radioactive dating for CS 29491-069 with the observed thorium and rare-earth element abundance pairs results in an average age of 9.5 Gyr, when based on solar r-process residuals, and 17.6 Gyr, when using HEW model predictions. Chronometry seems to fail in the case of HE 1219-0312, resulting in a negative age due to its high thorium abundance. HE 1219-0312 could therefore exhibit an overabundance of the heaviest elements, which is sometimes called an "actinide boost".

Short-time infusion of oxaliplatin in combination with capecitabine (XELOX30) as second-line therapy in patients with advanced colorectal cancer after failure to irinotecan and 5-fluorouracil

Tidskriftsartikel (refereegranskat)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.

- 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.

- This is a first attempt at a brief sketch of the history of biosensors. It is far from complete and rather unsystematic. Many names are still missing, and we apologize for this. But the authors hope to have laid a humble cornerstone for a future "Complete History of Biosensors". We hope that many of our colleagues will contribute!
