Based on the activity of single-agent paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) and the significant 1-year survival rates of patients with non-small cell lung cancer treated with carboplatin, the Hellenic Cooperative Oncology Group initiated a phase II trial using both agents in patients with inoperable stage III or IV disease to investigate the efficacy and toxicity of the combination. Since July 1995, 31 patients fulfilling all eligibility criteria entered this study. All patients received paclitaxel 175 mg/m2 as a 3-hour infusion and carboplatin dosed to an area under the concentration-time curve of 7, every 3 weeks. No granulocyte colony-stimulating factor was given. Among the 29 male and two female patients, the median age was 55 years (age range, 29 to 73 years) and the median Eastern Cooperative Oncology Group performance status was 1. Most of the patients had stage IV adenocarcinoma (19) with low differentiation (15). The median number of chemotherapy cycles was two, with a range of one to six. Among 21 patients evaluable, seven achieved a partial response, 10 had stable disease, and four had progressive disease. It is too early to evaluate nine patients. Grade 2/3 nonhematologic toxicity included alopecia (48%), neurotoxicity (3.7%), and myalgia/arthralgia (7.4%). Grade 2/3 neutropenia occurred in 11.1% of patients, whereas grade 2 thrombocytopenia was seen in only 3.7%. One patient died following complications of severe allergic reaction. In conclusion, although this study is ongoing, combination treatment using paclitaxel and carboplatin is both effective and well tolerated in patients with inoperable non-small cell lung cancer.

This phase I dose-escalation study was undertaken to determine the maximum tolerated doses of paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) and ifosfamide that could be administered without growth factors to previously untreated patients with non-small cell lung cancer. Forty patients with advanced non-small cell lung cancer were treated with a 3-hour infusion of paclitaxel and a 1-hour infusion of ifosfamide, repeated every 3 weeks. Groups of three patients each entered at escalating dose levels in a traditional phase I design. Starting doses were paclitaxel 100 mg/m2 and ifosfamide 3 g/m2; all patients received premedication with dexamethasone and diphenhydramine, and some also received a 5-HT3 blocker. Dose escalation was permitted only after full toxicity assessment had been completed for two cycles for all patients at a dose level. Dose escalation of paclitaxel continued to 225 mg/m2 without dose-limiting toxicity, but further escalation was not attempted because of the known likelihood of neurotoxicity above this dosage. Instead, ifosfamide was increased to 4 g/m2 for the final dose level. At these doses, dose-limiting myelosuppression was not seen, and there was only one episode of febrile neutropenia in 162 treatment cycles. Drug-related ifosfamide toxicities included gross hematuria and confusion in one patient each; paclitaxel-related symptoms included flu-like syndrome in most patients, arthralgia and/or myalgia in eight and 25 patients, respectively, and paresthesia in 14 patients. Despite premedication, 15 patients experienced grade 1 hypersensitivity reactions. Partial response was seen in 21% of patients (confidence interval, 9.3% to 36.5%), and the median duration of response was 5.9+ months (range, 3 to 14 months). The median survival was 9.1 months (range, 1 to 12 months). In summary, outpatient paclitaxel given over 3 hours and single-dose ifosfamide given over 1 hour may be combined safely without hematopoietic growth factors for the treatment of patients with non-small cell lung cancer. The recommended doses for phase II study are paclitaxel 225 mg/m2 and ifosfamide 4 g/m2, every 3 weeks.

The aim of this phase I study was to determine the maximum tolerated dose of a 3-h infusion of paclitaxel, combined with carboplatin at a fixed AUC of 7 mg ml-1 min every 4 weeks for up to six cycles and to evaluate any possible pharmacokinetic interaction. Twelve chemonaive patients with ovarian cancer were treated with paclitaxel followed by a 30-min infusion of carboplatin. Paclitaxel dose was escalated from 150 mg m-2 to 225 mg m-2 in cohorts of three patients. Carboplatin dose was based on renal function. Pharmacokinetic studies were performed in nine patients (at least two at each dose level). A total of 66 courses were evaluable for assessment. Grade 3 or 4 neutropenia was seen in 70% of the courses, however hospitalization was not required. Grade 3 or 4 thrombocytopenia occurred in 24% of the courses. Alopecia, myalgia and peripheral neuropathy were common but rarely severe. The pharmacokinetics of paclitaxel was non-linear and did not appear to be influenced by co-administration of carboplatin. The AUC of carboplatin was 7.0 +/- 1.4 mg ml-1 min, indicating that there was no pharmacokinetic interaction. The combination of carboplatin and paclitaxel may be administered as first-line treatment for advanced ovarian cancer. Although myelosuppression is the dose-limiting toxicity of the component drugs, the severity of thrombocytopenia was less than anticipated. The results of this study, with only a small number of patients, need to be confirmed in future investigations.

In order to determine the activity of paclitaxel in patients with relapsed or refractory non-Hodgkin's lymphoma (NHL), we conducted a phase II clinical trial in which eligible patients received paclitaxel 200 mg/m2 intravenously over 3 h. Treatment was repeated every 3 weeks. Patients achieving complete or partial responses after two courses of paclitaxel continued to receive therapy for a maximum of eight courses, otherwise they were removed from the study. Of 96 evaluable patients, 45 (47%) had primary refractory disease, and 51 (53%) had relapsed lymphoma. The median number of prior treatment regimens was two (range one to 10 regimens). 45 patients had lowgrade, 44 had intermediate-grade, and seven had mantle cell lymphoma. 24/96 patients responded (10 complete and 14 partial remissions) for an overall response rate of 25% (95% CI 17-35%). Patients with relapsed lymphoma had a higher response rate than those with primary refractory disease (19/51 = 37% v 5/45 = 11%; P < 0.01), and patients with relapsed intermediate-grade lymphoma had a higher response than those with relapsed low-grade lymphoma (9/18 = 50% v 10/31 = 32%; P = 0.22). The treatment was very well tolerated with the most common side-effects being alopecia (100%), peripheral neuropathy (35% of > or = grade II), and arthralgia/myalgia (25% of > or = grade II). After the first course of paclitaxel, grade III/IV thrombocytopenia and neutropenia were observed in 21% and 23% of the patients respectively. 23 episodes of neutropenic fever developed after 250 courses of paclitaxel therapy (8%). We conclude that paclitaxel, at this dose and schedule, is an active new drug for the treatment of non-Hodgkin's lymphoma. The activity of paclitaxel combination programmes are currently under investigation.

The aim of this study was to evaluate the efficacy of high-dose paclitaxel in patients with previously untreated stage IV epithelial ovarian cancer. Paclitaxel was administered intravenously over 3 h at a dose of 225 mg m(-2) on a 21-day cycle for six courses. Thirty-six patients were entered into this study; all 36 were assessed for toxicity and 33 patients were evaluable for response. One patient had a complete response and 12 patients had partial responses (overall response rate 39.4%, 95% CI 23-58%). The overall median duration of response was 9 months (range 3.5-23+ months). The response rate to carboplatin following failure of paclitaxel within 1 year of stopping therapy was 57% (four out of seven patients). The median survival of patients was 17.2 months. The main toxicity encountered was neutropenia which was WHO grade 3 in 11 patients (31%) and WHO grade 4 in seven patients (19%). Granulocyte colony-stimulating factor (GCSF) was not given to any patient during the study. Other toxicities were: grade 3/4 infection (11%) and nausea and vomiting (11%); grade 3 bone pain (22%), fatigue (14%), diarrhoea (3%), myalgia/arthralgia (3%) and dry eyes (3%). Transient peripheral neuropathy occurred in 16 patients (44%), and alopecia was encountered in most patients (grade 2/3, 78%). Paclitaxel given at 225 mg m(-2) to patients with stage IV epithelial ovarian cancer is active, well tolerated and does not require GCSF support.

Recently, a randomized study conducted by the Gynecologic Oncology Group (GOG 111) demonstrated that, given by a 24-hour infusion, the combination of cisplatin and paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) is superior to combination cisplatin/cyclophosphamide in previously untreated patients with advanced ovarian cancer. This combination, however, necessitates hospitalization. Combination paclitaxel/carboplatin would be expected to induce fewer nonhematologic side effects but may be more myelotoxic. Thus, we started a phase I dose-escalation study to determine the maximal tolerated dose of paclitaxel given as a 3-hour infusion in combination with carboplatin, both drugs administered every 21 days. The paclitaxel dose was escalated by increments of 25 mg/m2, starting at 135 mg/m2 (level 1), 160 mg/m2 (level 2), 185 mg/m2 (level 3), and 210 mg/m2 (level 4). Carboplatin was administered to achieve an area under the concentration-time curve of 5, using the Calvert formula For study levels 5 and 6, the carboplatin dose was targeted at area under the concentration-time curves of 6 and 7.5, respectively, and was combined with a fixed paclitaxel dose of 185 mg/m2. Thirty previously untreated patients with stage IIC to IV ovarian cancer were enrolled. Nonhematologic toxicity, including nausea/vomiting and arthralgia/myalgia, was mild. Across all dose levels, a total of 16 patients developed peripheral neurotoxicity (World Health Organization grades 1 and 2). At dose level 5, one patient experienced reversible grade 4 neurotoxicity. Neutropenia was the principal dose-limiting hematologic toxicity. During 33 (31%) of 106 courses, World Health Organization grade 4 neutropenia was observed. Granulocyte colony-stimulating factor was required in only 7.6% of courses. Thrombocytopenia was less than that expected when carboplatin is given alone. Clinical responses were observed in eight of 14 patients, for an overall response rate of 57%. The combination of carboplatin plus paclitaxel was found to be an active regimen. This trial demonstrates that carboplatin dosed by the Calvert equation and 3-hour paclitaxel can be combined safely at full therapeutic doses for six or more courses in patients with advanced epithelial ovarian cancer.

Preliminary results of this ongoing phase II study of paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) plus epirubicin administered as first-line treatment to women with metastatic breast cancer indicate encouraging response rates and no severe toxicity. Among the 57 patients admitted to this study, 52% had received prior adjuvant chemotherapy (85% with cyclophosphamide/methotrexate/5-fluorouracil), 46% had received radiotherapy, and 30% had received both forms of therapy; 63% of patients were postmenopausal, mainly with poorly differentiated tumors, and 80% presented with > or = 2 metastatic sites. Epirubicin 60 mg/m2 was administered intravenously as a 1-hour infusion followed by paclitaxel 175 mg/m2 infused over 3 hours. Standard premedication was given. Granulocyte colony-stimulating factor support was not used. Neutropenia was evident in 72% of cycles but was not severe. Instances of anemia and thrombocytopenia were rare. Alopecia was universal. All nonhematologic toxicity observed was mild or moderate (peripheral neuropathy, myalgia, nausea, vomiting World Health Organization toxicity grade < 2). At this time, 41 patients are currently evaluable for response, complete and partial remission are evident in seven and 21 patients, respectively. The overall response rate so far is 68%. An additional 12 patients show evidence of stable disease, and one has shown disease progression. Paclitaxel is considered a promising new drug in the adjuvant treatment of patients with metastatic breast cancer. Combining it with epirubicin allows safe administration with no evidence of severe cardiotoxicity. The incidence of adverse cardiac events was much lower than that observed with combinations of paclitaxel and doxorubicin.

A 7-year-old boy with T cell acute lymphoblastic leukemia developed disseminated hyalohyphomycosis due to Fusarium solani. The clinical features included fever, severe myalgia, documented fungemia with F. solani, an ecthyma gangrenosum-like lesion next to a peripheral venous catheter, and disseminated pustules. Severe neutropenia due to chemotherapy was the most relevant risk factor. Histopathologic study of the ecthyma gangrenosum-like lesion, as well as pustular lesions, revealed epidermal necrosis and an inflammatory infiltrate in the upper dermis, with numerous septate hyphae demonstrated by periodic acid-Schiff stain. Clinical resolution was achieved with granulocyte colony-stimulating factor and amphotericin B administration. Our case suggests that the peripheral venous access was probably the portal of entry of the fungus.

Our phase II study results demonstrating high efficacy and low toxicity for a weekly schedule of high-dose, 24-hour infusional 5-fluorouracil(5-FU)/folinic acid (HD5-FU/FA) in intensively pretreated patients with metastatic breast cancer prompted addition of paclitaxel (Taxol) to the regimen, for a phase I/II study of outpatient second-line treatment of metastatic breast cancer. That study further prompted the addition of cisplatin (Platinol) to the regimen for first-line treatment. So far, 28 patients with metastatic breast cancer have been evaluated. Pretreatment comprised adjuvant chemotherapy in 24 of 28 patients, but no prior chemotherapy for metastatic disease. Patients were treated with HD5-FU 2 g/m2 (24-hour infusion) plus FA 500 mg/m2 (2-hour infusion prior to FU) weekly for 6 weeks (days 1, 8, 15, 22, 29, and 36); in addition, paclitaxel 175 mg/m2 (3-hour infusion) was administered on days 0 and 21 and cisplatin 50 mg/m2 (1-hour infusion) on days 1 and 22 prior to HD5-FU/FA, repeated every 50 days. Patients were treated as outpatients using Port-a-Cath systems and portable pumps. Neutropenia was common (67% World Health Organization grade 3) but mild to moderate in most patients and was of short duration. No hospitalizations were required because of febrile neutropenia, and no granulocyte colony-stimulating factor support was used. Aside from common total alopecia, nonhematologic toxicities consisted mainly of moderate myalgia, diarrhea, mucositis, and nausea and vomiting. Hand-foot syndrome and peripheral neuropathy were cumulative and occurred most commonly during the third treatment cycle, with mild-to-moderate expression. In 28 patients with bidimensionally measurable disease, 25% (7/28) attained a complete response, 57% (16/28) achieved partial response, 11% (3/28) had stable disease, and 7% (2/28) had disease progression. Overall response was 82% (95% confidence interval, 66% to 100%). Eight of 28 patients are still receiving treatment. It is concluded that the combination of paclitaxel/cisplatin with weekly HD5-FU/FA appears to be effective in the first-line treatment of metastatic breast cancer. Preliminary results must be confirmed by the final analysis of response duration, time to progression, and survival.

Sixty patients with previously untreated non-small cell lung cancer of stages III and IV were treated with a 210 mg/m2 dose of paclitaxel by means of a 3-hour infusion. The objective response rate was 32% (95% confidence interval, 20-45%): 1 complete response and 18 partial responses. The median duration of response was 15 weeks, and the projected median survival duration of all patients was 30 weeks. Grade 3-4 neutropenia occurred in 73% of patients. Other grade 3-4 adverse events included anemia (5%), vomiting/nausea (8%), peripheral edema (2%), alopecia (7%), elevation of AST (2%), peripheral neuropathy (3%), allergic reaction (2%), arthralgia/myalgia (3%), and interstitial pneumonitis (3%). Paclitaxel administered at 210 mg/m2 by means of a 3-hour infusion every 3 weeks demonstrated a notable activity against previously untreated advanced non-small cell lung cancer, with a 32% major response rate. Major toxicity was neutropenia. Hypersensitivity, neurotoxicity, arthralgia/myalgia and cardiac toxicity were mild and easily managed.
