To assess the clinical usefulness of 2 novel therapies for treatment-resistant myositis.

Carcinoma of unknown primary (CUP) site accounts for approximately 6.5% of all cancers. Optimal therapy for patients with CUP has not yet been delineated. The current study was undertaken to evaluate response, time to treatment failure and survival in patients with CUP treated with a combination regimen comprising mitomycin C, epirubicin and cisplatin (MEP) versus mitomycin C alone (MITOC). Eighty-four patients with CUP were randomised to receive either the combination (MEP) or MITOC. Both treatment arms were well matched for age, gender, performance status, dominant site and number of disease sites. Eighty of the above patients were evaluable. Twenty patients (50%) treated with MEP responded to treatment compared with 7 (17%) who received MITOC. Grade III-IV hemopoietic toxicity was documented in 2 patients treated with MEP and no patients treated with MITOC. A single patient treated with MEP developed grade I peripheral neuropathy. Median time to treatment failure was 4.5 months for patients receiving MEP as opposed to 2 months for those receiving MITOC (p = 0.05). Median survival was 9.4 months in patients treated with MEP compared to 5.4 months in those receiving MITOC (p = 0.05). This study indicates that the addition of cisplatin and epirubicin to MITOC results in a significant improvement in the response rate, time to treatment failure and survival in patients with adenocarcinoma of unknown primary site.

To evaluate the impact on the response rate in patients with advanced breast cancer (ABC) of the doubling of the dose intensity (DI) of epirubicin monotherapy.

The aim of this Phase III, balanced randomised trial was to compare continuous intravenous infusion (CVI) of 5-FU with bolus (B) administration for metastatic colorectal cancer (CRC). One hundred and fifty-five non-pretreated patients were randomised to receive CVI 5-FU at a dose of 750 mg/m2/day (d), 7 d every 21 d (n = 77), or bolus 5-FU 500 mg/m2/d x 5 d every 28 d (n = 78). Incremental dose escalation at 50 mg per step was recommended in the absence of toxicity. All the patients had measurable metastatic disease (M), particularly, liver and a good performance status (WHO grade 0-1). Dose intensity was significantly higher in CVI than in the bolus group: 1369 mg/m2/week versus 558 mg/m2/week (P = 0.0001). Grade II-IV stomatitis was more frequent in the CVI group (31% versus 9%; P < 0.0001) as was hand and foot syndrome (14% versus 3%; P < 0.001). Diarrhoea (22% versus 12%) and grade III granulocytopenia (2% versus 6%) were comparable. Responses were more frequent in the CVI (26%) than in the bolus group (13%) (P < 0.04); progression-free survival was higher for the CVI group (P = 0.04), but there was no statistical difference in overall survival (median: 10 months (m) compared to 9 m), and 1 year survival (SD) 42% (6%) versus 40% (6%). In the multivariate analysis, survival was better for patients with a good PS, well-differentiated adenocarcinomas and a primary tumour without serosal extension. In conclusion, with a higher dose intensity, CVI 5-FU improved tumour control, but not overall survival.

This study was undertaken to determine if recombinant interferon-gamma (rIFN-gamma) given every other day as maintenance therapy could prolong the survival of patients with small cell lung cancer (SCLC) who achieved a complete or nearly-complete response to induction therapy. A secondary endpoint was to assess the toxicity of alternate day doses of this treatment. One hundred and seventy seven patients in complete or nearly-complete response following chemotherapy with or without thoracic radiotherapy were studied. Patients were randomised to receive either rIFN-gamma 4 million units (0.2 mg) subcutaneously every other day for 4 months or observation. One hundred and twenty of the 127 registered patients were eligible; 59 patients received IFN and 61 patients without maintenance therapy were followed. Alternate day IFN was reasonably well tolerated by the majority of patients, but in 12% substantial non-haematological toxicity (including flu-like syndrome) occurred. One of 3 patients with pneumonitis died after having received 3.6 mg IFN. The median survival time from the date of randomisation was 8.9 months for the IFN arm and 9.9 months for the observation arm. rIFN-gamma at the dose and schedule used in this study failed to prolong response duration and survival in SCLC patients in complete or nearly-complete response. The toxicity seen with every other day doses of IFN was less than that reported with daily dosing. The hypothesis that this agent may increase the deleterious effects of radiation on normal lung tissue was supported by the development of pneumonitis in 3 cases of whom 1 had a fatal outcome. The results do not warrant further studies with rIFN-gamma on maintaining response in SCLC.

To evaluate specific biological markers to improve understanding and use of granulocyte colony-stimulating factor (G-CSF) in patients receiving chemotherapy

The antiemetic effectiveness and safety of single-dose oral granisetron were compared with intravenous (I.V.) ondansetron in chemotherapy-naive patients who received moderately emetogenic chemotherapy.

To compare the pharmacokinetics of the approved I.V. (intravenous) mesna regimen and an investigational I.V.-oral regimen that could be used in outpatients who receive ifosfamide.

Hot flashes represent a substantial clinical problem for some breast cancer survivors. Although estrogen or progesterone preparations can alleviate these symptoms in many patients, concern remains regarding the use of hormonal preparations in such women. Thus, there is a perceived need for nonhormonal treatments for hot flashes for breast cancer survivors. Based on anecdotal evidence that vitamin E was helpful, we designed a trial to investigate this matter.

To compare two doses of letrozole and megestrol acetate (MA) as second-line therapy in postmenopausal women with advanced breast cancer previously treated with antiestrogens.

To determine whether high-dose infusional fluorouracil (FU) is effectively modulated by leucovorin (LV), interferon (IFN) alpha-2b, or both when given to patients with metastatic colorectal cancer.

This multicentre, randomised, double-blind, double-dummy, parallel group study was investigated in order to compare on 3 days the efficacy and the safety of the 16 mg once a day (od) ondansetron suppository (suppository group) with the recommended ondansetron treatment, i.e. 8 mg intravenous (i.v.) ondansetron on day 1 followed by 8 mg tablet (p.o.) twice daily (i.v. + p.o. group) on days 2 and 3 in patients receiving cisplatin (> or = 50 mg/m2) containing chemotherapy. In the 420 patients included in the intent-to-treat population, 209 received the 16 mg suppository and 211 the i.v. + p.o. treatment. The number of emetic episodes and the nausea score were recorded each day. Concerning the primary criterion, both treatments provided good anti-emetic control with 87% of all patients having a complete or major response (0-2 emetic episodes) on day 1 in the suppository group and 92% in the i.v. + p.o. group (P = 0.058). The 90% confidence interval for the difference between the two treatments for complete or major control was included in the interval (-15%, 15%) and showed that the treatment groups could be regarded as equivalent. Small differences in favour of the i.v. + p.o. group were observed concerning the secondary parameters. Both treatments were well tolerated. The results of this study show that both treatments are equivalent in the prevention of cisplatin-containing chemotherapy induced emesis for the primary efficacy criteria and that the ondansetron suppository is efficient and well tolerated and is a suitable alternative to the anti-emetic treatment combining the intravenous and oral routes.

The present investigation has examined the clinical benefits of tobramycin, polymyxin E and amphotericin therapy in the management of oral mucositis in children undergoing chemotherapy prior to bone marrow transplantation. Tobramycin, polymyxin E, and amphotericin reduced the degree of oral mucositis more than conventional therapy of diphenhydramine, Maalox, and local analgesic. While there was a statistically significant fall in the severity of the mucositis with tobramycin, polymyxin E and amphotericin, this was unlikely to be of practical benefit.

To evaluate the possibility of predicting development of heart failure, we monitored left ventricular ejection fraction (LVEF) in addition to demographic data in patients with advanced breast cancer treated with epirubicin.

Patients with metastatic nonsmall cell lung carcinoma (NSCLC) usually have a poor prognosis. A chemotherapy regimen containing cisplatin is commonly used for symptom palliation. Echinomycin is a potent bifunctional intercalator of double-strand DNA; trimetrexate is a new derivative of methotrexate and is active against methotrexate-resistant tumor cells in vitro.

Our previous randomised trial in patients with advanced ovarian cancer indicated a significant response and survival advantage for those receiving high-dose (100 mg/m2) as compared with low-dose (50 mg/m2) cisplatin in combination with cyclophosphamide (750 mg/m2). However, this was accompanied by more toxicity; peripheral neuropathy was troublesome, with 32% of patients experiencing > or = WHO grade 2 at the cisplatin dose of 100 mg/m2. Nimodipine is a calcium-channel antagonist that has provided protection from cisplatin-induced neurotoxicity in a rat model system. We performed a pilot study in 50 patients that demonstrated the feasibility of co-administration of nimodipine in a chronic oral dosing schedule with cisplatin-based chemotherapy in an open-label non-randomised trial. This led us to initiate a double-blind, placebo-controlled, randomised trial in patients with ovarian cancer, which was prematurely discontinued because of problems with nausea and vomiting, leading to poor patient compliance, that were not predicted by the pilot study. These studies did not demonstrate a neuroprotective effect for nimodipine. The primary efficacy variable, i.e, the neurotoxicity score at the end of treatment, gave a significantly lower mean for placebo patients than for nimodipine patients. This report details our experience and discusses the reasons for premature termination of the randomised trial.

The population pharmacokinetic/pharmacodynamic (PK/PD) approach was prospectively integrated in the clinical development of docetaxel to assess the PK profile in a large population of patients and investigate systemic exposure as a prognostic factor for clinical outcome.

We conducted a randomized trial to evaluate primarily the cardioprotective effect of dexrazoxane (DEX) in patients with advanced breast cancer and soft tissue sarcomas (STS) treated with high-dose epirubicin (EPI). We wished also to determine the value of radioimmunoscintigraphy (RIS) in the assessment of anthracycline cardiotoxicity.

This study was designed to test the hypothesis that the modulations of the human immune system in relation to in vivo whole body hyperthermia may be ascribed to elevations in the plasma epinephrine and norepinephrine concentrations. In a single-blind, controlled, cross-over study, 8 healthy volunteers were selectively infused norepinephrine and epinephrine, respectively, for 1 h, in order to obtain twofold increases in the plasma concentrations of these hormones, thereby mimicking the increases seen during in vivo whole body hyperthermia. Epinephrine infusion increased baseline, interleukin-2 and interferon-alpha stimulated natural killer cell activity, and the percentage and concentration of cluster designation (CD)16+ cells, whereas the neutrophil and lymphocyte count or the CD3+, CD4+, CD8+, CD19+ and CD14+ cell subtypes were not influenced. Norepinephrine infusion did not cause any changes in these variables. It is concluded that epinephrine, but not norepinephrine, may be responsible for the hyperthermia-induced effects on natural killer cells.
