  • Clinical benefit and quality of life in patients with advanced pancreatic cancer receiving gemcitabine plus capecitabine versus gemcitabine alone : a randomized multicenter phase III clinical trial--SAKK 44/00-CECOG/PAN.1.3.001

    • PURPOSE: To compare clinical benefit response (CBR) and quality of life (QOL) in patients receiving gemcitabine (Gem) plus capecitabine (Cap) versus single-agent Gem for advanced/metastatic pancreatic cancer. PATIENTS AND METHODS: Patients were randomly assigned to receive GemCap (oral Cap 650 mg/m(2) twice daily on days 1 through 14 plus Gem 1,000 mg/m(2) in a 30-minute infusion on days 1 and 8 every 3 weeks) or Gem (1,000 mg/m(2) in a 30-minute infusion weekly for 7 weeks, followed by a 1-week break, and then weekly for 3 weeks every 4 weeks) for 24 weeks or until progression. CBR criteria and QOL indicators were assessed over this period. CBR was defined as improvement from baseline for >or= 4 consecutive weeks in pain (pain intensity or analgesic consumption) and Karnofsky performance status, stability in one but improvement in the other, or stability in pain and performance status but improvement in weight. RESULTS: Of 319 patients, 19% treated with GemCap and 20% treated with Gem experienced a CBR, with a median duration of 9.5 and 6.5 weeks, respectively (P < .02); 54% of patients treated with GemCap and 60% treated with Gem had no CBR (remaining patients were not assessable). There was no treatment difference in QOL (n = 311). QOL indicators were improving under chemotherapy (P < .05). These changes differed by the time to failure, with a worsening 1 to 2 months before treatment failure (all P < .05). CONCLUSION: There is no indication of a difference in CBR or QOL between GemCap and Gem. Regardless of their initial condition, some patients experience an improvement in QOL on chemotherapy, followed by a worsening before treatment failure.

  • Gemcitabine plus capecitabine compared with gemcitabine alone in advanced pancreatic cancer : a randomized, multicenter, phase III trial of the Swiss Group for Clinical Cancer Research and the Central European Cooperative Oncology Group
  • 2007
  • Ingår i: Journal of Clinical Oncology. - 0732-183X .- 1527-7755. ; 25:16, s. 2212-2217

    • Purpose: This phase III trial compared the efficacy and safety of gemcitabine (Gem) plus capecitabine (GemCap) versus single-agent Gem in advanced/metastatic pancreatic cancer. Patients and Methods: Patients were randomly assigned to receive GemCap (oral capecitabine 650 mg/m2 twice daily on days 1 to 14 plus Gem 1,000 mg/m2 by 30-minute infusion on days 1 and 8 every 3 weeks) or Gem (1,000 mg/m2 by 30-minute infusion weekly for 7 weeks, followed by a 1-week break, and then weekly for 3 weeks every 4 weeks). Patients were stratified according to center, Kamofsky performance score (KPS), presence of pain, and disease extent. Results: A total of 319 patients were enrolled between June 2001 and June 2004. Median overall survival (OS) time, the primary end point, was 8.4 and 7.2 months in the GemCap and Gem arms, respectively (P = .234). Post hoc analysis in patients with good KPS (score of 90 to 100) showed a significant prolongation of median OS time in the GemCap arm compared with the Gem arm (10.1 v 7.4 months, respectively; P = .014). The overall frequency of grade 3 or 4 adverse events was similar in each arm. Neutropenia was the most frequent grade 3 or 4 adverse event in both arms. Conclusion: GemCap failed to improve OS at a statistically significant level compared with standard Gem treatment. The safety of GemCap and Gem was similar. In the subgroup of patients with good performance status, median OS was improved significantly. GemCap is a practical regimen that may be considered as an alternative to single-agent Gem for the treatment of advanced/metastatic pancreatic cancer patients with a good performance status.

  • CA 19-9 tumour-marker response to chemotherapy in patients with advanced pancreatic cancer enrolled in a randomised controlled trial
  • 2008
  • Ingår i: The Lancet Oncology. - 1470-2045 .- 1474-5488. ; 9:2, s. 132-8
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Several studies in patients undergoing chemotherapy for advanced pancreatic carcinoma have linked a decrease in the concentration of the tumour marker carbohydrate antigen (CA) 19-9 to lengthened survival. The aim of this study was to test the hypotheses that an early decrease in baseline serum CA 19-9 concentration (on day 42, after two cycles of chemotherapy) by at least 50% is associated with lengthened survival, and that a decrease in CA 19-9 concentration of at least 50% from the baseline concentration to the lowest value measured at any time during treatment (nadir) is of prognostic significance, enabling its use as a surrogate endpoint for survival. METHODS: CA 19-9 serum concentration was measured at baseline and every 3 weeks thereafter in patients with histologically proven advanced pancreatic carcinoma enrolled in a randomised trial of gemcitabine versus gemcitabine plus capecitabine. Patients were excluded if baseline serum CA 19-9 concentration was below the upper limit of normal (ULN) in the laboratory or if this measurement was missing. Comparisons of survival between patients with and without a CA 19-9 response were corrected for the guarantee-time bias by the landmark method. The trial on which this study is based is registered on the clinical trials site of the US National Cancer Institute website http://www.clinicaltrials.gov/ct/show/NCT00030732. FINDINGS: 247 of 319 randomised patients were assessable for analysis of baseline serum CA 19-9 concentration, and, of these, 175 patients were assessable for tumour-marker response to treatment. Median overall survival for patients with a baseline CA 19-9 concentration equal to or above the median value (ie, 59xULN) was 5.8 months (95% CI 5.1-7.0), which was significantly shorter than that for patients with baseline concentrations below the median value (10.3 months [95% CI 8.6-12.8], p<0.0001). An early decrease in CA 19-9 concentration of at least 50% after two cycles of chemotherapy was not associated with a longer overall survival compared with patients who did not have a decrease of at least 50% (median 10.1 months [9.2-12.7] vs 8.6 months [6.9-11.2], p=0.53; hazard ratio for death 1.11 [0.81-1.52]). Furthermore, a decrease in CA 19-9 concentration of at least 50% reached at the CA 19-9 nadir concentration was not associated with a longer overall survival compared with those patients who did not have a decrease of at least 50% (median 7.8 months [6.5.10.1] vs 6.7 months [5.5-9.8], p=0.74; 0.95 [0.69-1.31]) after adjusting for the guarantee-time bias. INTERPRETATION: Pretreatment serum CA 19-9 concentration is an independent prognostic factor for survival, but a decrease in concentration during chemotherapy is not significantly associated with lengthened survival compared with those who did not have a corresponding decrease. Our data suggest that CA 19-9 response during chemotherapy is not a valid surrogate endpoint for survival in clinical trials.
