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.

Chronic oral VP-16 (Etoposide) is a chemotherapy regimen with wide application in oncology and documented efficacy against germ cell tumors, lymphomas, Kaposi sarcoma, and glial brain tumors. Eight patients ranging in age from 4 to 36 years (median 7.5 years) with locally recurrent medulloblastoma were treated with VP-16. No patient displayed evidence of cerebrospinal fluid dissemination, distant brain or spine parenchymal metastases, or extraneural metastatic disease. All patients had previously been treated with surgery (gross total resection, 5; subtotal resection, 3), craniospinal radiotherapy, and platinum-based chemotherapy (adjuvant, 3; salvage, 8). Each cycle of therapy consisted of 21 days of VP-16 (50 mg/m2/day) followed by a 7 to 14 day rest followed by an additional 21 days of VP-16 (50 mg/m2/day). Complete blood counts were obtained weekly. Neurologic examination and brain magnetic resonance imaging scan with contrast were performed prior to each cycle of therapy. Treatment-related complications included: partial alopecia (5 patients); diarrhea (4); weight loss (3); anemia (2); neutropenia (4); and thrombocytopenia (4). Two patients required transfusion and 1 patient received antibiotics for neutropenic fever. All patients were evaluable for response: 3 demonstrated progressive disease after the first cycle of VP-16, 3 had stable disease (range 4 to 6 months) and 2 had partial neuroradiographic responses (8 and 10 months). Median duration of response and stable disease was 6 months (range: 4 to 10 months) in 5 of 8 (62.5%) patients. Chronic oral VP-16 is a well-tolerated and relatively non-toxic chemotherapeutic agent with demonstrated activity in locally recurrent medulloblastoma.

Two open, phase II studies were performed to evaluate the activity and toxicity of infusional topotecan in patients with advanced non-small-cell lung carcinoma (NSCLC) and advanced breast cancer who had not received previous chemotherapy for metastatic disease. Twenty-five patients with an ECOG performance score < 2 were treated with infusional topotecan administered as a daily, continuous intravenous infusion starting at 0.6 mg m(-2) day(-1) (NSCLC) and 0.5 mg m(-2) day(-1) (breast cancer) for 21 days every 4 weeks. Three patients achieved a partial response as defined by WHO criteria: one with NSCLC (8%; 95% CI 0-39%) and two with advanced breast cancer (15%; 95% CI 2-45%). The major toxicities were neutropenia and thrombocytopenia, with one episode of neutropenic sepsis. These data suggest that topotecan delivered as a continuous intravenous infusion over 21 days as single-agent therapy does not appear to offer a clinical advantage over conventional 5-day schedules against advanced NSCLC and advanced breast cancer.

We demonstrated in an earlier trial that paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) has substantial antineoplastic activity, with acceptable toxicity, in patients with advanced metastatic esophageal cancer. Preclinical and clinical data from studies in other tumors indicate substantial additive or even synergistic activity for paclitaxel/cisplatin combination chemotherapy. We encountered substantial toxicity with a cisplatin/paclitaxel/5-fluorouracil combination. To maximize paclitaxel dose, we initiated a phase II trial using cisplatin and paclitaxel alone. This report summarizes preliminary data from that trial. Paclitaxel 200 mg/m2 is given as a continuous, 24-hour infusion on day 1. On day 2, cisplatin 75 mg/m2 is given. Courses are repeated every 21 days. Dose adjustments are based on myelosuppression, neurotoxicity, and (for cisplatin) renal or auditory toxicity. All patients receive recombinant human granulocyte colony-stimulating factor to minimize the risk of neutropenic fever. The primary end point of the study is tumor regression. Secondary end points include duration of response and toxicity. Two groups of patients are being studied. Those with advanced metastatic disease receive chemotherapy alone as palliative treatment. The second group has locoregional disease that is potentially resectable. These patients receive combined-modality therapy involving induction paclitaxel/cisplatin chemotherapy followed by surgery. To date, 37 evaluable patients have been treated. Twenty had advanced metastatic disease and 17 were treated before planned surgery. Twenty-seven patients had adenocarcinoma and 10 had epidermoid carcinoma. Major objective responses were seen in 49% of all patients, with similar response rates for patients with metastatic and locoregional disease. The median duration of response for patients with metastases is 4+ months. Among 14 patients treated before surgery, one experienced a complete pathologic response, and the neoplasms of 43% were downstaged. Primary toxicity was neutropenia, which was tolerable. Surgical morbidity or mortality did not increase. Cisplatin plus paclitaxel is an active combination in the treatment of patients with advanced or locoregional esophageal cancer. Further studies with this combination both in metastatic and locally advanced disease are indicated.

The aim of this phase II study was to characterise the efficacy and toxicity of semisynthetic paclitaxel in patients with metastatic breast cancer. Eligible patients had measurable disease and had been treated with one prior chemotherapy regimen either as adjuvant or for metastatic disease. Semisynthetic paclitaxel was given at a dose of 175 mg/m2 over 3 h every 21 days with dexamethasone, cimetidine and diphenhydramine premedications. 31 patients were entered. All were evaluable for toxicity. 30 patients were evaluable for response because 1 patient was lost to follow-up after receiving one cycle. One patient achieved a complete response and 10 patients achieved partial responses for an overall response rate (CR + PR) of 37% (95% confidence interval 20-56%). 17 patients (55%) experienced at least one episode of grade 3 or 4 neutropenia. There were two episodes of febrile neutropenia complicating 155 cycles of therapy. One of these resulted in a treatment-related death in a patient with pulmonary metastasis. 3 patients required dose reductions for grade 3 sensory neuropathy. Our study shows that the antitumour activity and toxic effects of semisynthetic paclitaxel appear to be identical to the naturally occurring product.

A phase II study was conducted to evaluate the activity of paclitaxel and carboplatin in advanced head and neck cancer. Twenty-four patients with measurable locoregional squamous cell carcinoma and metastatic disease were entered. All had been heavily pretreated with radiotherapy, surgery and chemotherapy and were at second recurrence or disease progression when they entered the trial. Patients received Paclitaxel 200 mg/m2 with carboplatin 7 AUC once every 3 weeks with premedication with dexamethasone and diphenyldramine and ranitidine. Twenty-three patients were evaluable for response. Four patients (17%) achieved a complete response and 5 (22%) a partial response for an overall response rate of 39%. Duration of response was 3-9 months. Toxicity was tolerable. Four patients showed Grade III (WHO) and 6 Grade II neutropenia. Nineteen (79%) of patients who received more than two courses of chemotherapy presented neurotoxicity. The combination of paclitaxel and carboplatin was effective in heavily pretreated patients with squamous cell carcinoma of the head and neck.

Pamidronate (APD) is a potent inhibitor of bone resorption that is useful in the management of patients with osteolytic bone metastases from breast cancer or multiple myeloma, tumour-induced hypercalcaemia or Paget's disease of bone. After intravenous administration, the drug is extensively taken up in bone, where it binds with hydroxyapatite crystals in the bone matrix. Matrix-bound pamidronate inhibits osteoclast activity by a variety of mechanisms, the most important of which appears to be prevention of the attachment of osteoclast precursor cells to bone. In patients with osteolytic bone metastases associated with either breast cancer or multiple myeloma, administration of pamidronate together with systemic antitumour therapy reduces and delays skeletal events, including pathological fracture, hypercalcaemia and the requirement for radiation treatment or surgery to bone. Pamidronate generally improves pain control. Quality-of-life and performance status scores in pamidronate recipients were generally as good as, or better than, those in patients who did not receive the drug. Overall survival does not appear to be affected by pamidronate therapy. Tumour-induced hypercalcaemia also responds well to pamidronate therapy: 70 to 100% of patients achieve normocalcaemia, generally 3 to 5 days after treatment. Response durations vary, but are commonly 3 weeks or longer, In comparative studies, pamidronate produced higher rates of normocalcaemia and longer normocalcaemic durations than other available osteoclast inhibitors, including intravenous etidronate, clodronate and plicamycin (mithramycin). In most patients with Paget's disease of bone, intravenous pamidronate reduces bone pain and produces biochemical response. Serum alkaline phosphatase levels generally fall 50 to 70% from baseline 3 to 4 months after pamidronate treatment. Biochemical response may be prolonged. Pamidronate is well tolerated by most patients. Transient febrile reactions, sometimes accompanied by myalgias and lymphopenia, occur commonly after the first infusion of pamidronate. Other reported adverse events include transient neutropenia, mild thrombophlebitis, asymptomatic hypocalcaemia and, rarely, ocular complications (uveitis and scleritis). Pamidronate should be considered for routine use together with systemic hormonal or cytotoxic therapy in patients with breast cancer or multiple myeloma and osteolytic metastases. At present, pamidronate is the drug of choice for first-line use in the management of patients with tumour-induced hypercalcaemia. It is an effective treatment for Paget's disease and is the treatment of choice where oral bisphosphonates are not an option.

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.

To determine the maximally tolerated dose of paclitaxel with and without filgrastim (G-CSF) when administered as a 24-hour intravenous infusion after a 120-hour infusion of gallium nitrate at a fixed dose of 300 mg/m2/24 hours, 40 patients were entered onto a trial lasting from September 1994 to September 1996. Eligibility included a diagnosis of an advanced malignancy not amenable to curative therapy and up to one previous chemotherapy regimen for metastatic disease. Gallium was administered at a fixed dose of 300 mg/m2/day as a continuous intravenous infusion for 120 hours. Paclitaxel starting at 90 mg/m2 was given concurrently with the last 24 hours of the gallium as a 24-hour intravenous infusion. Cycles were repeated every 21 days. Once the maximum tolerated dose (MTD) of paclitaxel was reached, G-CSF (5 microg/kg/day days 7-16) was added and paclitaxel dose escalation continued. The MTD for paclitaxel without G-CSF was 110 mg/m2 and 225 mg/m2 with G-CSF, with neutropenia being the dose-limiting toxicity. A partial response was noted in a patient who had thymoma and a complete response was achieved in a patient who had colon cancer. The recommended phase II dosage is gallium nitrate at 300 mg/m2/day over 120 hours, with paclitaxel at 110 mg/m2 over 24 hours without G-CSF or 225 mg/m2 over 24 hours with G-CSF and 0.5 mg calcitriol on days 1 through 7. Further trials of this modified regimen for outpatient administration are in progress.

The Hoosier Oncology Group conducted a trial evaluating ifosfamide in patients who had recurrent or metastatic squamous cell carcinoma of the head and neck. Patients must have received no prior chemotherapy for metastatic disease. If prior adjuvant chemotherapy was given, the last cycle must have been at least six months from time of recurrence. All patients were required to have a Karnofsky performance status of > or = 50. Twenty-four patients received treatment consisting of ifosfamide, 1.5 g/m2/day for 5 days, with cycles repeated every 3 weeks. Mesna, 300 mg/m2, was administered intravenously 15 minutes before ifosfamide and 4 and 8 hours after ifosfamide on days 1 through 5. Toxicity was predominantly hematologic, with grade 3--4 neutropenia seen in 13 patients resulting in 4 episodes of neutropenic fever. One partial response was seen in 23 evaluable patients for an overall response rate of 4.3% (95% confidence interval, 0, 12.7%). In conclusion, ifosfamide would appear to have limited single-agent activity in squamous cell carcinoma of the head and neck.
