Abstract:
A phase I trial was performed to evaluate the feasibility of escalating the dose of etoposide in dose-intensive ifosfamide, carboplatin, and etoposide (ICE) with granulocyte-macrophage colony-stimulating factor (GM-CSF).Twenty-four patients were entered between November 1990 and November 1991. Patients received ifosfamide 5 g/m2 by continuous infusion over 48 hours, carboplatin 400 mg/m2 by intravenous bolus, and GM-CSF 5 micrograms/kg/d subcutaneously from day 4 until neutrophil recovery. The etoposide dose was escalated, with six patients receiving 300 mg/m2 total dose (level 1), six receiving 600 mg/m2 (level 2), three receiving 900 mg/m2 (level 3), and five receiving 1,200 mg/m2 (level 4). Level 4B consisted of three patients who received etoposide 1,200 mg/m2 and GM-CSF 10 micrograms/kg/d. Cycles were repeated every 21 days. The maximum-tolerated dose (MTD) was prospectively defined as the dose level at which the next higher level produced greater than 7 days of grade 4 myelosuppression in two or more of six patients.Twenty-three patients were assessable. The median duration of neutropenia was < or = 7 days on cycle 1 at all dose levels. The initial criteria for determination of the MTD was never achieved. However, seven of eight patients treated at levels 4 and 4B required hospitalization for neutropenic fever on cycle 1 of therapy, with three of four septic events occurring at these levels. Cumulative thrombocytopenia occurred at all dose levels, with > or = 50% of patients requiring platelet transfusions on cycle 3. This became the dose-limiting toxicity above level 3. The overall response rate was 48%, with 11 of 23 objective responses, including two complete responses (CRs). Seven of 11 (64%) patients with non-small-cell lung cancer (NSCLC) responded, including one CR. Two of four (50%) heavily pretreated non-Hodgkin's lymphoma (NHL) patients responded, with one CR.The addition of GM-CSF to a dose-intensive ICE regimen permitted dose escalation of etoposide to 900 mg/m2, with cumulative thrombocytopenia as the dose-limiting toxicity. Carboplatin dosing by the area under the curve (AUC) may minimize thrombocytopenia. This appears to be an active regimen for patients with NSCLC and refractory NHL.Keywords:

Background. Although the survival of children with soft tissue sarcoma (STS) has improved considerably, the outcome of patients with metastatic disease, and those with primary tumours of the extremities or parameningeal sites remains disappointing. We describe the clinical outcome of an ifosfamide-based regimen with local therapy directed only to children who failed to achieve a complete response to initial chemotherapy.Patients and Methods. Twenty-one children with STS (16 rhabdomyosarcoma) who presented with unresectable tumours were treated with five courses of ifosfamide (9 g/m(2)) and etoposide (600 mgm(2)). Patients who did not achieve a complete response then received local therapy. Chemotherapy with ifosfamide combined with etoposide, vincristine (1.5 mg/m(2) and doxorubicin (60 mg/m(2)) or vincristine and actinomycin D (1.5 mg/m(2)) was continued for one year.Results and Discussion. Objective responses to five courses of ifosfamide and etoposide were seen in all patients. Disease free survival (DFS) at a median follow up of 59 months was 57% (95% CI 29-75%). The DFS of children who received local therapy was 89% compared with 33% in those who received chemotherapy alone (p=0.027). Locoregional recurrences did not occur in children who received radiotherapy to the site of the primary tumour. Ifosfamide-based chemotherapy does not reduce the incidence of loco-regional recurrence in children who do not receive local therapy.

Intracranial germ cell tumor is sometimes associated with Down syndrome; however, no optimal treatment has been developed due to the high risk of recurrence and treatment-related mortality. Here, we report on a patient with an intracranial germinoma in the bilateral basal ganglia. The patient received 3 courses of ifosfamide-cisplatin-etoposide in combination with whole-brain irradiation (24 Gy), with no serious complications. The patient is alive and disease free 16 months after the initial diagnosis. This regimen is a feasible treatment for intracranial germ cell tumor associated with Down syndrome, although careful attention must be paid to the increased risk for severe infection.

Twelve FIGO stage III-IV ovarian cancer patients progressing or relapsing after primary cisplatin-containing combination chemotherapy were treated with ifosfamide and etoposide. Only patients with clinically evaluable disease entered the trial. The 12 patients received a median number of 3 courses (range 1-6). No complete or partial response and two disease stabilizations were observed. Ten patients progressed on therapy. The combination of ifosfamide and etoposide does not appear to be an effective salvage treatment for advanced ovarian cancer.

Background. Ifosfamide has previously been shown to be active as a single agent and in combination with doxorubicin, etoposide, and teniposide in pediatric solid tumors and adult acute leukemia. The authors performed a dose-escalation trial of ifosfamide with a fixed dosage of etoposide, with mesna uroprotection, in children with multiply recurrent acute leukemia. Methods. Chemotherapy was administered daily for 5 days. Etoposide 100 mg/m2 was followed by ifosfamide at an initial dosage of 1.6 g/m2. The ifosfamide was escalated in 20% increments to the maximum tolerated dosage in cohorts of three patients. Mesna 400 mg/m2 was given immediately before the ifosfamide and then at 3 and 6 hours after ifosfamide in the initial patients. Subsequent patients were treated with mesna 400 mg/m2 just before ifosfamide, and then every 2 hours to a total dosage equal to the ifosfamide dosage. Results. Forty-four heavily pretreated patients were entered on study. Forty were evaluable for toxicity and 36 for response as well. The maximum tolerated dosage of ifosfamide was 4.0 g/m2/d for 5 days (20 g/m2/course). Overall, 10 patients achieved complete remission, and 3 achieved partial remission. Remissions were brief, although four patients went on to bone marrow transplant while in remission. One patient is still alive. Conclusions. The combination of etoposide and ifosfamide with mesna uroprotection showed promising activity in children with multiply recurrent acute leukemia.

The result of a combination consisting of ifosfamide and etoposide was evaluated in 57 patients suffering from non‐Hodgkin's lymphoma (NHL) who had relapsed or were resistant to adriamycin‐containing combinations. Some of the patients (35%) also received methotrexate. 80% of the patients belonged to the histology group ‘high‐grade’ malignant NHL. 1times1 of the 57 patients (19%) obtained a remission, 5 of these were complete and 6 partial. The remission predominantly occurred in the group of patients with ‘high‐grade’ malignant histopathology who were treated at the first relapse after complete remission or when front‐line treatment induced a partial remission and ifosfamide and etoposide were added in direct connection with frontline treatment. It is concluded that the use of the combination of ifosfamide and etoposide should be limited to such patients.

SummaryEighteen patients with localized and extensive small cell cancer and no prior therapy were treated with an intensive induction chemotherapy program consisting of a combination of etoposide, ifosfamide and cisplatinum (VIP). Limited disease patients achieving a complete response after 5 cycles of VIP received 40 Gy to the primary tumor site and mediastinum, and cranial radiotherapy (30 Gy).The objective response rate was 94 Wo with 53% complete and 41 % partial responses. Median survival time for all patients was 65 weeks, median actuarial survival for limited disease was 72 weeks and 60 for extensive disease. Toxicity was significant as expected.

Purpose. The study was performed to assess the antitumour activity and toxicity of a 72-h continuous infusion of single-agent etoposide as second-line treatment for patients with locally advanced or metastatic soft tissue sarcoma (STS), following reports of substantial activity using this schedule of etoposide administration as first-line treatment in combination with ifosfamide.Patients/method. This was an open phase I/II trial performed at a single institution in patients with metastatic or locally advanced STS who had failed first-line treatment with doxorubicin + ifosfamide combination chemotherapy or, less commonly, single-agent treatment with doxorubicin or ifosfamide. Etoposide was given as a continuous intravenous infusion over 72 h. The starting dose level was 200 mg m(-2) day(-1) x 3 escalating in 10% steps in cohorts of three patients until dose-limiting toxicity was encountered.Results. Seventeen patients were treated, median age 47 years (range 26-71 years). No responses were seen in 16 assessable patients despite etoposide levels in the cotoxic range. The steady-state plasma concentration exceeded 8 mug ml-(1) in all patients and in patients treated at >/= 600 mg m -(2) the mean steady-state level was 14.4 mug ml -(1). The median event-free survival was 6 weeks (95% confidence interval (CI) 3.31-8.69) and the overall survival 16 weeks (95% CI 9.28-22.72). The maximum tolerated dose in this pretreated patient group was 200 mg mm(-2) day(-1) x 3. The dose-limiting toxicity was myelosuppression.Discussion. Etoposide given by 72-h infusion is inactive as second-line chemotherapy in STS. It is associated with significant toxicity when given in these doses, in this patient group.
