          Abstract

          We studied the activity of combined oxaliplatin and fluorouracil-leucovorin in 16 consecutive patients with advanced biliary tract adenocarcinomas. The disease control rate (responses and stable disease) was 56% (95% confidence interval, 29–84%) and the median overall survival time was 9.5 months (range 0.9–26.8+). Therefore, this regimen might be active in biliary adenocarcinomas with further evaluation necessary.

          Chemotherapy improves survival and quality of life in advanced pancreatic and biliary cancer.

          In certain patients with pancreatic and biliary cancer, chemotherapy may relieve tumour-related symptoms, improve quality of life and possibly prolong survival. The extent of these improvements is not completely known in spite of the extensive use of this treatment modality. The aim of this study was to estimate any gain in the quantity and quality of life produced by chemotherapy in patients with pancreatic and biliary cancer. Between January 1991 and February 1995, 90 eligible patients with pancreatic or biliary cancer were randomized to either chemotherapy in addition to best supportive care or to best supportive care. Chemotherapy was allowed in the latter group if the supportive measures did not lead to palliation. Chemotherapy was either sequential 5-fluorouracil/leucovorin combined with etoposide (FELv) or, in elderly and poor performance patients, the same regimen without etoposide (FLv). Quality of life was evaluated with the EORTC-QLQ-C30 instrument. Mean scale scores in the QLQ-C30 improved more often/deteriorated less frequently in the chemotherapy group than in the best supportive care group. More patients in the chemotherapy group (36%, 17/49) had an improved or prolonged high quality of life for a minimum period of 4 months compared to those in the best supportive care group (10%, 4/41, P < 0.01). Overall survival was significantly longer in the chemotherapy group (median 6 vs. 2.5 months, P < 0.01). Also, the quality-adjusted survival time was longer for patients randomized to chemotherapy (median 4 vs. 1 months, P < 0.01). The effects were seen both in pancreatic and biliary cancer. The results show that chemotherapy can add to both quantity and quality of life in advanced pancreatic and biliary cancer. The number of patients who benefit from treatment is, however, still limited; for this reason careful selection before, and close monitoring during, treatment are necessary.

            Phase II trial of two-weekly gemcitabine in patients with advanced biliary tract cancer.

            Patients with advanced biliary tract carcinoma face a dismal prognosis as no effective palliative therapy has been defined. The aim of the present phase II investigation was to evaluate the therapeutic efficacy and tolerance of a two-weekly high-dose gemcitabine regimen in this patient population. Thirty-two consecutive patients with locally unresectable or metastatic biliary tract cancer were enrolled in this multicenter phase II trial. Treatment consisted of gemcitabine 2200 mg/m2 given as a 30-min intravenous infusion every two weeks for a duration of six months unless there was prior evidence of progressive disease. After a median number of 12 treatment courses, 7 of 32 (22%) patients had a partial response that lasted for a median duration of 6.0 months (range 3.5-10.0). Fourteen additional patients (44%) had stable disease, whereas eleven patients (34%) progressed despite therapy. The median time to progression was 5.6 months (range 1.8-13.0); median survival time was 11.5 months (range 3.0-24.0), and the probability of surviving beyond 12 months was 44%. The tolerance of treatment was remarkable with only two patients each experiencing grade 3 leukocytopenia, granulocytopenia and/or thrombocytopenia, and one patient had grade 3 anaemia. Similarly, nonhaematologic side effects were infrequent, and generally mild to moderate. Two-weekly high-dose gemcitabine seems to represent a potentially effective, safe and well-tolerated regimen for the palliative treatment of patients with advanced biliary tract cancer.

              Antitumor activity of oxaliplatin in combination with 5-fluorouracil and the thymidylate synthase inhibitor AG337 in human colon, breast and ovarian cancers.

              Oxaliplatin, classical [5-fluorouracil (5-FU)] and non-classical (AG337) thymidylate synthase inhibitors have shown promising activity in the treatment of cancer. This study investigates the cytotoxic effects of oxaliplatin in combination with 5-FU and AG337 in cultured human colon (HT29, CaCo2), breast (MCF-7, MDA-MB-231) and ovarian (2008) cancer cell lines, and their derived counterparts selected for their resistance to 5-FU (HT29-5-FU), doxorubicin (MCF-7mdr) or cisplatin (2008C13). Therapeutic experiments were conducted in mice bearing colon-HT29 xenografts and in the GR hormone-independent mammary carcinoma model. In vitro, oxaliplatin shows potent cytotoxic activity in colon (IC50 from 2.1 +/- 1.1 to 5.9 +/- 1.7 microM), ovarian (IC50 = 10 +/- 1.6 microM) and breast cancer cells (IC50 from 7.4 +/- 2.7 to 17.9 +/- 7.1 microM). Oxaliplatin was a potent inhibitor of DNA synthesis and bound to cellular DNA. Surprisingly, the overall amount of oxaliplatin DNA binding was significantly inferior to that induced by isocytotoxic concentrations of cisplatin in HT29 (p=0.026). In vitro, synergistic antiproliferative effects were observed when oxaliplatin was added to 5-FU and AG337. Those synergistic effects of combinations were maintained in colon HT29-5-FU cancer cells. In vivo, 5-FU increased significantly the antitumor activity of oxaliplatin in HT29 xenografts (p=0.0036), and similarly 5-FU and AG337 increased the activity of oxaliplatin in the GR tumor model (p=0.0012). These data may encourage further clinical investigation of oxaliplatin in combination with classical and non-classical thymidylate synthase inhibitors in the treatment of human cancers.
