A phase I and pharmacokinetic study of the combination of capecitabine and docetaxel in patients with advanced solid tumours

Capecitabine and docetaxel are both active against a variety of solid tumours, while their toxicity profiles only partly overlap. This phase I study was performed to determine the maximum tolerated dose (MTD) and side-effects of the combination, and to establish whether there is any pharmacokinetic interaction between the two compounds. Thirty-three patients were treated with capecitabine administered orally twice daily on days 1–14, and docetaxel given as a 1 h intravenous infusion on day 1. Treatment was repeated every 3 weeks. The dose of capecitabine ranged from 825 to 1250 mg m–2twice a day and of docetaxel from 75 to 100 mg m–2. The dose-limiting toxicity (DLT) was asthenia grade 2–3 at a dose of 1000 mg m–2bid of capecitabine combined with docetaxel 100 mg m–2. Neutropenia grade 3–4 was common (68% of courses), but complicated by fever in only 2.4% of courses. Other non-haematological toxicities were mild to moderate. There was no pharmacokinetic interaction between the two drugs. Tumour responses included two complete responses and three partial responses. Capecitabine 825 mg m–2twice a day plus docetaxel 100 mg m–2was tolerable, as was capecitabine 1250 mg m–2twice a day plus docetaxel 75 mg m–2. © 2000 Cancer Research Campaig

Adaptive intrapatient dose escalation of cisplatin in combination with low-dose vp16 in patients with nonsmall cell lung cancer

The objective of this phase II and pharmacologic study was to explore the feasibility toxicity and activity of adaptive intrapatient dose escalation of cisplatin in a dose-intensive weekly schedule using predefined levels of exposure, with the ultimate aim to improve the antitumour activity of the therapy in patients with nonsmall cell lung cancer (NSCLC). Platinum DNA-adduct levels in peripheral white blood cells during treatment were used as the primary parameter for adaptive dosing. If DNA-adduct levels were not available, the area under the concentration-time curve (AUC) of unbound platinum in plasma was used for dose adaptation. Target levels for DNA-adducts and AUC have been defined in a previously performed pharmacologic study. The feasibility of adaptive dosing was tested in 76 patients with stage IIIB and IV NSCLC, who were planned to receive 6 weekly courses of cisplatin at a starting dose of 70 mg m-2, together with daily low oral dose of 50 mg VP16. In total, 37 patients (49%) who were given more than one course received a dose increase varying from 10 to 55%. The majority of patients reached the defined target levels by a dose increase during course two. Relevant grade 2 neurotoxicity was observed in eight (10%) patients and reversible ototoxicity grade 2 in 14 (18%) patients. The strategy of adaptive intrapatient dose adjustment of cisplatin is practically feasible in a research setting even when results for dose adaptation have to be reported within a short time-period of I week. The toxicity appeared to be manageable in this cohort of patients. In some patients, exposure after the standard dose was substantially lower than the defined target level and significant dose escalations of more than 50% had to be applied. The response rate (RR) was relatively high: overall 40% (29 out of 72 patients) partial remission (PR), in patients with stage IIIB the RR was 60% (15 out of 25 patients) and with stage IV 30% (14 out of 47 patients). Randomised studies are needed to determine whether the adaptive dosing strategy results in better efficacy than standard dosing

An EORTC gastrointestinal group phase II evaluation of epirubicin combined with 5-fluorouracil in advanced adenocarcinoma of the pancreas

The EORTC Gastrointestinal Group has conducted a phase II trial in 47 patients with locally advanced or metastatic adenocarcinoma of the pancreas with epirubicin 90 mg/m2 intravenously on day 1 in combination with 5-fluorouracil 500 mg/m2 in a 2 hr infusion day 1-4, every 4 weeks. Of 43 evaluable patients there were six early deaths due to tumour progression and one due to a cerebrovascular accident. There were six partial responses for a response rate of 14% including early deaths. The median survival for all patients was 4 months. It is concluded that the addition of 5-fluorouracil to epirubicin does not appear to enhance the therapeutic results of epirubicin alone. © 1987.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Cis-platinum as second-line chemotherapy in advanced gastric adenocarcinoma. A phase II study of the EORTC gastrointestinal tract cancer cooperative group

Thirty-four patients with measurable metastatic gastric adenocarcinoma refractory to prior chemotherapy were treated with cis-platinum 100 mg/m2 in a 6-hr infusion at 3-week intervals. Thirty-one patients were evaluable for response. There were three complete and three partial responses. Median duration of response was 4 months. Toxicity consisted mainly of nausea and vomiting and was severe in 12 patients. One patient had a severe but reversible renal failure. These results confirm other data reported in the literature. Cis-platinum has activity in gastric adenocarcinoma and should now be further investigated in first-line chemotherapy. © 1985.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Tamoxifen as a single agent for advanced melanoma in postmenopausal women. A phase II study of the EORTC malignant melanoma cooperative group

Between 1983 and 1989 a phase II study was carried out by the EORTC Malignant Melanoma Cooperative Group in which postmenopausal women with advanced melanoma but a good performance status received tamoxifen, 40 mg per day, as a single agent. From 12 centres, 114 patients were registered of whom 107 appeared to be eligible and 102 evaluable. Seven died of progressive disease within 4 weeks, eight others had early progressive disease (of whom seven died within 7 weeks). The response rate was 4.9%, the complete response rate 1%. Without prior chemotherapy three of 58 responded, with prior chemotherapy two of 44. Except for one of 46 patients with lung metastases who experienced a PR of these metastases, all responders were patients with slowly growing small soft tissue metastases. We conclude that, because of the few side effects, tamoxifen can be recommended for (postmenopausal) patients who have only a small number of slowly growing metastases and who are not yet candidates for treatment with toxic drugs. © 1992 Rapid Communications of Oxford Ltd.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Evidence-based guideline on management of colorectal liver metastases in the Netherlands

A Dutch national evidence-based guideline on the diagnosis and treatment of patients with colorectal liver metastases has been developed. The most important recommendations are as follows. For synchronous liver metastases, spiral computed tomography (CT) or magnetic resonance imaging (MRI) should be used as imaging. For evaluation of lung metastases, imaging can be limited to chest radiography. For detection of metachronous liver metastases, ultrasonography could be performed as initial modality if the entire liver is adequately visualised. in doubtful cases or potential candidates for surgery, CT or MRI should be performed as additional imaging. For evaluation of extrahepatic disease, abdominal and chest CT could be performed. Fluorodeoxyglucose positron emission tomography could be valuable in patients selected for surgery based on CT (liver/abdomen/chest), for identifying additional extrahepatic disease. Surgical resection is the treatment of choice with a five-year survival of 30 to 40%. Variation in selection criteria for surgery is caused by inconclusive data in the literature concerning surgical margins <10 mm, presence of extrahepatic disease and the role of (neo)adjuvant therapy. To minimise variation in selection criteria, selection should be performed according to this guideline and preferably in qualified centres. If resection is not possible due to extensive disease, palliative chemotherapy is recommended. Systemic chemotherapy with fluoropyrimidine first-line chemotherapy (5-FU/Leucovorin) combined with irinotecan or oxaliplatin should be considered as standard regimens. Radiofrequency ablation, isolated hepatic perfusion, portal vein embolisation, and intra-arterial chemotherapy are considered experimental and should only be performed as part of a clinical research protoco
