When administered as a single agent in pretreated patients with advanced breast cancer, paclitaxel (Taxol) exhibits remarkable antitumor activity. This trial was undertaken to compare paclitaxel with standard chemotherapy as front-line therapy for this disease. Patients with measurable or evaluable metastatic breast cancer, no prior chemotherapy for metastatic disease, and an Eastern Cooperative Oncology Group performance status of 0 to 2 were randomized to receive paclitaxel 200 mg/m2 intravenously over 3 hours for eight cycles (6 months) or standard treatment with oral cyclophosphamide (Cytoxan) 100 mg/m2/d days 1 through 14, intravenous methotrexate 40 mg/ m2 days 1 and 8, intravenous 5-fluorouracil 600 mg/m2 days 1 and 8, and oral prednisolone 40 mg/m2/d (CMFP) days 1 through 14 for six cycles (6 months). Patients whose disease progressed or relapsed were recommended to receive second-line epirubicin. Accrual has been completed with 208 patients randomized, but a preplanned interim analysis of the first 100 patients is reported here. Analysis of quality of life, assessed by a linear analogue scale and overall quality of life indices, is ongoing. Objective response occurred in 31% (confidence interval, 19% to 45%) with paclitaxel and 35% (confidence interval, 22% to 51%) with CMFP with stable disease in an additional 33% and 29%, respectively. Median time to progression was 5.5 months for paclitaxel-treated patients and 6.4 months for those given CMFP, with median survival durations of 17.3 and 11.3 months, respectively. Grades 3 and 4 neutropenia occurred in 64% of patients treated with paclitaxel and in 63% treated with CMFP. However, febrile neutropenia was the primary reason for hospitalization in 1% of paclitaxel courses, compared with 8% of CMFP courses. Nine percent of the patients had major infections with CMFP, but none were seen with paclitaxel. Moderate or severe mucositis occurred in 13% of paclitaxel-treated and 27% of CMFP-treated patients. Alopecia and peripheral neuropathy were more common with paclitaxel. Quality of life assessments in the first 100 patients suggest better overall results on paclitaxel treatment as compared with CMFP. Preliminary analyses suggest that single-agent paclitaxel is well tolerated and provides comparable control of metastatic cancer to CMFP combination therapy when used as front-line treatment.

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.

Prostate carcinoma is the most commonly associated with osseous metastases malignancy in males. The lesions, being usually of a mixed sclerotic/lytic variety and less often of the pure sclerotic type, need to be treated by a bone seeking radioactive element with an as low as possible radiobiological burden on the surrounding (peritumoral) tissues. Rhenium-186-HEDP was used to treat these osseous metastatic lesions due to its bone seeking kinetics attractive radiochemical properties. Of a total of 16 prostate cancer patients. 3 experiment loss of pain, 8 experienced obvious and 2 some improvement. No change was observed in 3 patients. Ten patients manifested a flare syndrome increasing pain approximately 2 to 6 days, after Re-186-HEDP i.v. application. Six patients showed a definite and 9 a slight decrease in platelet levels and absolute number of polymorphonuclear white blood cells, up to fourth week following treatment. One patient underwent a whole blood transfusion and in 2 peripheral neuropathy was observed lasting about 9 to 12 days. Re-186-HEDP appears to be a promising new metal ion complex for the palliation of painful bone metastases in prostate cancer. Compared to Sr-89 therapy, it shows a longer analgetic efficacy and has the advantage of emitting gamma rays, a fact which facilitates dosimetric calculations.

When administered as a single agent to previously treated patients with advanced breast cancer, paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) has good activity. This trial was undertaken to compare paclitaxel with standard chemotherapy as front-line treatment for this disease. Patients with measurable or evaluable metastatic breast cancer, no prior chemotherapy for metastatic disease, and Eastern Cooperative Oncology Group performance status of 0 to 2 were randomized to receive either paclitaxel 200 mg/m2 intravenously over 3 hours for eight cycles over 24 weeks or standard treatment with oral cyclophosphamide 100 mg/m2/d days 1 to 14, intravenous methotrexate 40 mg/m2 days 1 and 8, intravenous 5-fluorouracil 600 mg/m2 days 1 and 8, and oral prednisone 40 mg/m2 daily days 1 to 14 (CMFP) for six cycles over 24 weeks. Patients whose disease progressed or relapsed were recommended for second-line therapy with epirubicin. Accrual has been completed with 209 patients randomized, and an interim analysis of the first 100 patients is reported here. Analysis of quality of life, assessed by the linear analogue scale and overall quality of life indices, is ongoing. Objective response occurred in 31% (confidence interval, 19% to 45%) with paclitaxel and 35% (confidence interval, 22% to 51%) with CMFP, with stable disease in an additional 33% and 29%, respectively. Median time to progression was 5.5 months with paclitaxel and 6.4 months with CMFP, with a median survival of 17.3 months for patients treated with paclitaxel and 11.3 months for those given CMFP. Grades 3 and 4 neutropenia occurred in 64% of patients with paclitaxel and 63% with CMFP. However, febrile neutropenia was the primary reason for hospitalization in 1% of paclitaxel courses, compared with 8% with CMFP. Major infections (World Health Organization grade 4) were seen in 7% of patients treated with CMFP, but in none of those given paclitaxel. Moderate or severe mucositis occurred in 13% of paclitaxel and 27% of CMFP patients. Alopecia and peripheral neuropathy were more common with paclitaxel. Quality of life assessments in the first 100 patients suggest better overall results for those treated with paclitaxel compared with CMFP. Preliminary analyses suggest that single-agent paclitaxel is well tolerated and provides control of metastatic cancer comparable to that of CMFP combination therapy when used as front-line therapy in an outpatient setting.

Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ), the first taxane used in routine clinical practice, has aroused considerable interest for its high single-agent activity against breast cancer and for its novel mechanism of action. Epirubicin, the 4' epimer of doxorubicin, is another agent with a high activity against breast cancer and is known for its lower rate of toxic side effects, especially toxic cardiac events, compared with its mother compound. The combination of paclitaxel and doxorubicin yielded response rates between 63% and 93% in phase I/II studies. In these studies, however, the investigators reported severe cardiac toxic events. The rationale for the current study was therefore to evaluate the combination of paclitaxel/epirubicin, focusing mainly on cardiac toxicity. In two groups, 85 patients with metastatic breast cancer entered the study. Approximately 20% of the patients had primary metastatic breast cancer with large tumors at the primary site. Half of the patients had received adjuvant chemotherapy. Study medication in group A consisted of epirubicin 60 mg/m2 given intravenously over 1 hour, followed by paclitaxel 175 mg/m2 administered as a 3-hour intravenous infusion after premedication with steroids, antihistamines, and H2-blockers. In group B, epirubicin 90 mg/m2 was combined with paclitaxel 175 mg/m2, given in the same manner as in group A. Dose escalation to 225 mg/m2 paclitaxel was planned in both groups. The main toxicity in both groups was neutropenia (73% World Health Organization grade 3/4 in group A and 93% in group B). Other hematologic side effects were rare. No febrile neutropenia was reported in group A, but two episodes occurred in group B. Peripheral neuropathy, arthralgia, and myalgia were mild (only World Health Organization grades 1 and 2). Alopecia was universal. In group A, the paclitaxel dose could be escalated to 200 mg/m2 in 15 patients and to 225 mg/m2 in seven patients. Dose reduction due to severe neutropenia was necessary in 11 patients. No cardiac events were reported in group A. In group B, the paclitaxel dose could be escalated to 200 mg/m2 in only one patient, and no patient reached 225 mg/m2. Three patients needed a dose reduction. In this group, one patient had a greater than 10% decrease in the left ventricular ejection fraction with no clinical signs. In group A, 43 patients were evaluable for response; in group B, 25 patients were evaluable. Thirteen patients were out of protocol with only bone metastasis, and two patients had more than one prior chemotherapy for metastatic disease. The response rate was identical in both groups, with five complete remissions and 24 partial remissions in group A and three complete responses and 14 partial remissions in group B. The duration of response was 8.2 months in both groups. The median cumulative epirubicin dose was 420 mg/m2 in group A and 630 mg/m2 in group B. The combination of paclitaxel 175 mg/m2 and epirubicin 60 or 90 mg/m2 can be administered safely to patients with metastatic breast cancer. Although response was not the primary end point of this trial, the response data are nonetheless encouraging and suggest that further evaluation of this combination-line treatment of metastatic breast cancer is warranted.

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)/leucovorin (LV) in intensively pretreated patients with metastatic breast cancer prompted the addition of paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) 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 to the regimen for first-line treatment. Twenty-eight 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 high-dose 5-FU 2 g/m2 (24-hour infusion) plus LV 500 mg/m2 (2-hour infusion before 5-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 before high-dose 5-FU/LV, repeated every 50 days. Patients were treated as outpatients using Port-a-Cath systems (SIMS Deltec Inc, St Paul, MN) and portable pumps. Neutropenia was common but mild to moderate and of short duration in most patients. 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% (seven of 28) attained a complete response, 57% (16 of 28) achieved a partial response, 11% (three of 28) had stable disease, and 7% (two of 28) had disease progression. Overall response was 82% (95% confidence interval, 66% to 100%). We conclude that the combination of paclitaxel/cisplatin with weekly high-dose infusional 5-FU/LV 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.

Thirty-three metastatic breast cancer patients with prior chemotherapy (adjuvant alone, 9 patients; chemotherapy for metastatic disease alone, 13 patients; chemotherapy for both, 11 patients) received paclitaxel (Taxol) 135 mg/m2 over 1 h followed by vinorelbine (Navelbine) 30 mg/m2 over 10 minutes on day 1 every 3 weeks. All patients had contraindications to receive anthracycline therapy (primary resistance, 10 patients; dose reaching the maximum recommended dose and/or myocardiopathy, 23 patients). Twenty-eight patients had previously received anthracyclines, and the remaining 5 had received prior CMF (cyclophosphamide, methotrexate, fluorouracil). The combination of paclitaxel plus vinorelbine was given as first-line chemotherapy for metastatic disease to 9 patients and as second- or third-line to the remaining 24 patients. The mean number of metastatic sites was 2 (range 1-5). Twenty-two patients had visceral involvement. Overall, 3 complete and 13 partial responses were observed among the 33 patients (objective response rate 48.5%, 95% confidence interval 31% to 66.5%). The response rate in patients receiving the regimen as first-line chemotherapy was 67% (6/9 patients), compared to 42% (10/24) in those receiving the regimen as second- or third-line chemotherapy. Primary anthracycline-resistant patients showed a response rate of 60% (6/10), whereas the remaining patients had a response rate of 43.5% (10/23). The main toxicities were grade 3 alopecia (92%), grade 3-4 neutropenia (28%), neutropenic fever (16%), grade 1-2 peripheral neuropathy (44%), arthralgias-myalgias (32%), and hypersensitivity reactions (8%). Phlebitis was a significant clinical problem in patients receiving the drugs through a peripheral vein.

This phase I/II study investigated the efficacy and toxic effects of combination chemotherapy using paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ), ifosfamide, and cisplatin (TIP) in patients with recurrent or metastatic squamous cell carcinoma of the head and neck. Twelve patients were entered in the phase I part of the study, results of which were reported previously. Fifty-three patients were treated in the phase II part of the study with 175 mg/m2 paclitaxel in a 3-hour infusion on day 1; 1,000 mg/m2/d ifosfamide in a 2-hour infusion on days 1 to 3; and 60 mg/m2 cisplatin on day 1, repeated every 3 to 4 weeks. Thirty-five men and 18 women were treated; the median age was 55 years (range, 27 to 73 years). Sites of disease and types of previous therapy varied among the patients. Among those with recurrent disease, 30 had locoregional disease, four had locoregional disease with distant metastasis, and 17 had distant metastasis only. Two patients had distant metastatic disease (MI) at the time of diagnosis. Of the 53 patients entered, 52 were assessable for disease response and toxic effects. Complete response was achieved in nine (17%) of 52 patients and partial response in 21 (40%); five (10%) patients had stable disease and 17 (33%) had progressive disease. When response rate was analyzed by disease sites, patients with locoregional sites showed a 43% major response (complete and partial) rate, and those with distant metastatic sites demonstrated an 80% major response rate (P=.04). The median duration of disease response in all patients was 4.9 months at completion of the study. Among the nine patients with complete response, three had progressive disease and the median duration of response was 6.9 months (range, 4.9 to 17 months); six were still in remission at the time of this writing, with a median duration of response of 12.8 months (range, 6.3 to 18.8+ months). The median survival time was 8.8 months, and the 1- and 2-year survival rates were 40% and 21.9%, respectively. The median follow-up time of the study was 11.8 months. The major toxic effects included neutropenia, cumulative peripheral neuropathy, and fatigue. Mucositis was rare; grade 3 mucositis developed in only one patient. Other side effects included neutropenic fever in 14 patients, all of whom completely recovered after antibiotic treatment. Grade 3 orthostatic hypotension and grade 3 peripheral neuropathy developed in one patient; supportive care led to gradual recovery. No deaths were caused by toxic effects. In conclusion, these preliminary results indicate that the TIP chemotherapy regimen produced high rates of major responses in patients with recurrent or metastatic head and neck squamous cell carcinoma, and responses were durable. The median, 1-year, and 2-year survival times were particularly promising. The TIP regimen should be pursued further as an induction regimen for locally advanced head and neck cancer.

Between May 1995 and July 1997, paclitaxel (TX) (175 mg/m2 by 3 h i. v. infusion every 21 days) was administered to 70 consecutive patients (median age: 57 years) previously treated with the FEC regimen (cyclophosphamide and 5-fluorouracil, 600 mg/m2, plus epirubicin, 60 or 120 mg/m2) as an adjuvant setting or as a first-line therapy for metastatic disease. Sixty-eight patients were evaluable for response, while two died early. Patients received a median of 4.7 (3-12 course) of TX for a total of 211 courses. The overall response and stable disease rate was 54% in 11 patients, who relapsed following adjuvant FEC, and 60% in 57 patients, who received FEC as first treatment for their metastatic disease. No complete respose was obtained. In patients pretreated for metastatic disease, response and stable disease rates were similar irrespective of previous response to FEC. Main hematologic toxicity of TX was of short duration, grade II/III leukopenia (86% of patients) and non-hematologic toxicity was grade II/III peripheral neuropathy, related to the cumulative dose of TX. At this schedule, TX offers a significant rate of partial responses or disease stabilization in patients with metastatic breast cancer previously treated with FEC.

We conducted a Phase IB trial of antidisialoganglioside chimeric 14. 18 (ch14.18) antibody and interleukin 2 (IL-2) to determine the maximal tolerated dose (MTD), immunological effects, antitumor effects, and toxicity of this treatment combination. Twenty-four melanoma patients received immunotherapy with ch14.18 antibody and a continuous infusion of Roche IL-2 (1.5 x 10(6) units/m2/day) given 4 days/week for 3 weeks. The ch14.18 antibody (dose level, 2-10 mg/m2/day) was scheduled to be given for 5 days, before, during, or following initial systemic IL-2 treatment. The ch14.18 MTD was 7.5 mg/m2/day, and 15 patients were treated with the ch14.18 MTD. Immunological effects included the induction of lymphokine-activated killer activity and antibody-dependent cellular cytotoxicity by peripheral blood mononuclear cells. In addition, serum samples obtained following ch14.18 infusions were able to facilitate in vitro antibody-dependent cellular cytotoxicity. Antitumor activity included one complete response, one partial response, eight patients with stable disease, and one patient with >50% decrease of hepatic metastases in the face of recurrence of a s.c. lesion. Dose-limiting toxicities were a severe allergic reaction and weakness, pericardial effusion, and decreased performance status. Most patients treated at the MTD had abdominal, chest, or extremity pain requiring i.v. morphine. One patient had an objective peripheral neuropathy. This IL-2 and ch14.18 treatment combination induces immune activation in all patients and antitumor activity in some melanoma patients. We are attempting to enhance this treatment approach by addition of the anti-GD3 R24 antibody to this IL-2 and ch14.18 regimen.
