The combination of etoposide and cisplatin has become one of the standard treatments for small cell lung cancer. Ifosfamide, an analogue of cyclophosphamide, has demonstrated single-agent antitumor activity comparable with that of the most active agents used to treat small cell lung cancer. Because ifosfamide is relatively nonmyelosuppressive and its principal dose-limiting toxicity, urotoxicity, has largely been eliminated with the introduction of the uroprotective agent mesna, we undertook a phase II study of the combination of all three agents (etoposide/ifosfamide/cisplatin) in good-performance-status, extensive-disease patients 70 years of age or younger. Twenty-five patients (17 men and eight women; median age, 58 years) were treated with 75 mg/m2 etoposide, 20 mg/m2 cisplatin, and 1.0 g/m2/d ifosfamide administered intravenously for 5 days. Mesna (200 mg/m2) was given as a bolus prior to the first day of chemotherapy and then daily by continuous infusion (900 mg/m2 over 24 hours) between administrations of chemotherapy. Mesna was continued for 12 hours after the last dose of ifosfamide. Treatment cycles were planned every 4 weeks for four cycles. Due to severe toxicities in the first eight patients, subsequent patients received only 4 days of treatment (20% dose reduction). Of the 25 extensive-disease patients studied, 23 are evaluable for response. Seven (30%) achieved a complete response and 10 (43%) had a partial response (overall response rate, 73%). Five patients (22%) had stable disease (< 50% decrease and no evidence of disease progression for at least 4 weeks), and disease progressed in 1 patient (4%). The median survival time was 42 weeks (range, 2 to 160+ weeks). Granulocytopenia was dose-limiting: median granulocyte count was 0.486 x 10(9)/L, 21% of cycles had a granulocyte nadir below 0.2 x 10(9)/L, and four patients died of sepsis. Three patients required platelet transfusion and nine needed blood transfusion. Microscopic hematuria occurred in eight patients (11% of treatment cycles) but was reversible in all cases. A number of central nervous system symptoms were reported but could not be definitely attributed to ifosfamide/mesna. Gastrointestinal toxicity was generally mild, which is attributed to the use of an aggressive antiemetic program. The etoposide/ifosfamide/cisplatin regimen is active and produced a complete response rate of 30% in extensive small cell lung cancer; the duration of response and survival appears similar to that of other standard regimens. The 5-day schedule produced excessive toxicity in this patient population, necessitating a 20% dose reduction (by using a 4-day schedule). The method of administration required a minimum of 5 hospital days per cycle.(ABSTRACT TRUNCATED AT 400 WORDS)

Thirty-seven patients with widely metastatic malignant melanoma were treated with one of three chemotherapy regimens, incorporating high-dose dacarbazine (DTIC). The chemotherapy was followed by autologous bone marrow rescue which was harvested under local anesthesia in 25 of the patients. The three regimens comprised a 24-hour infusion of DTIC (Regimen A for patients less than 45 years of age, 4.3 to 10.5 g/m2; B, if greater than 45 years of age 2.7 to 4.0 g/m2; and later C, if greater than 45 years of age 7.0 to 8.0 g/m2). The second alkylating agent was given at +8 and +16 hours from the start of DTIC. The total doses of the melphalan ranged from 60 to 130 mg/m2 for Regimen A and 30 to 40 mg/m2 for Regimen B. Ifosfamide 5.0 to 8.0 g/m2 was given instead of melphalan in Regimen C. The response rates for the regimens were 81% (25% CR) for A, 27% (11% CR) for B, and 20% (with no complete responders) for Regimen C. There was no statistically significant difference between the three regimens for survival with a median value of 6 months. One of the 16 patients treated with the very high dose Regimen A died of septicemia and three of ten patients in Regimen C died within the first 2 weeks of treatment. There was statistically significant greater myelosuppression, stomatitis, and diarrhea in the very high dosage DTIC and melphalan (Regimen A) compared with the other two regimens. No significant difference in response rate or toxicity was observed for the different dosages escalated within each of the three regimens. Although hematologic and gastrointestinal toxicity were very severe, no unusual side effects were noted except for one episode of severe acute renal failure in the high-dose DTIC and melphalan, Regimen A. Responses occurred mainly in nonvisceral, nodal, and cutaneous sites and occasionally in pulmonary metastases. The Karnofsky performance improved 4 to 6 months after treatment notably with the high-dose DTIC and melphalan therapy. No survival benefit for the combination chemotherapy despite the high dosages was detected and such an approach currently cannot be recommended.

Thirty-two patients with advanced epidermoid carcinoma of the esophagus were treated with ifosfamide (1.50 gm/m2 daily x 5 days) with uroprotective mesna in a phase II study. Eighteen patients were previously untreated. Of 28 evaluable patients, two (7%) had partial remissions lasting 2+ and 6+ months. Toxicity was predominantly myelosuppression with a median WBC nadir of 1.8 cells/ul. Seven patients required hospitalization for nadir sepsis. Ifosfamide has minimal activity in esophageal cancer and causes severe myelosuppression.

We have evaluated the activity of ifosfamide in 75 patients with recurrent sarcomas and pediatric solid tumors. All patients had previously received cyclophosphamide in combination with other chemotherapeutic agents. Ifosfamide was administered as a continuous 5 day infusion at a dose of 1800 mg per M2, except in the last 14 patients who received the drug as a daily one hour infusion at the same dose level. Partial response was observed in 9 of 20 patients with Ewing's sarcoma, 2 of 9 patients with rhabdomyosarcoma, 3 of 17 patients with osteogenic sarcoma and 4 of 29 patients with various other neoplasms. A further 6 patients had stable disease, defined as the absence of progression for at least 6 cycles of therapy. Thus overall response rate was 24%, with the highest response rate of 45% being observed in Ewing's sarcoma. Toxicity was acceptable, although there was quite marked leucopenia (median nadir 700) with less profound thrombocytopenia (median nadir 87,000). Sepsis occurred in 3 patients but no patient died as a result of infection. Hematuria occurred in 43% of patients who did not receive mesna, and in 26% of patients who did, although prior pelvic irradiation was found to be a significant risk factor for hematuria. Only 1 of 14 patients without prior pelvic irradiation or hematuria developed hemorrhagic cystitis when treated with ifosfamide and mesna. Confusional states developed in 6 patients. We conclude that ifosfamide is an active agent in patients with relapsed sarcomas and childhood solid tumors, even when such patients have been previously treated with cyclophosphamide.

25 Patients with metastatic non-seminomatous testicular neoplasms were treated by surgery and cytostatic therapy using a combination consisting of Velban, Bleomycin, Cis-Platinum and/or Ifosfamid. In 22 patients this procedure induced a persistant complete remission with a mean observation time of 23 months. 2 patients died because of post-surgical complications after a second-look-lymphadenectomy. They suffered from rapidly progressive tumor disease. One patient died in a septicemia during chemotherapy. Our experience is that morbidity of an effective chemotherapy should not be underestimated. Transient bone marrow suppression, anorexia, alopecia and hyperpigmentation are unavoidable. However, severe vomiting, disturbed electrolyte metabolism, hemorrhagic cystitis, anemia and septicemia can well be managed by respective supportive care. Septicemia, for instance, may be treated with appropriate antibiotics without inducing tubular necrosis. Supportive measures also will avoid severe chronic defects of ear and kidney function.

Three patients with stage 4 neuroblastoma were treated with a schedule comprising alternating modules of myelosuppressive (ifosfamide, etoposide, doxorubicin) and less myelosuppressive (vincristine, cisplatin) drugs given every 10 days regardless of the neutrophil count. A partial response was seen in two patients, and a very good partial response, in one patient. Extensive blood-component support was required. Non-haemopoietic toxicity was severe and led to treatment delays in two patients. Ifosfamide-related encephalopathy was seen in one patient and nephrotoxicity, in two patients. Mucositis was severe in two patients, may have contributed to the high rate of sepsis observed, and precluded the use of doxorubicin in one patient. As ifosfamide and doxorubicin were felt to be responsible for much of the toxicity, a subsequent schedule did not include these agents.

Despite reported activity in many other solid tumors, high-dose ifosfamide produces few objective responses in recurrent pediatric brain tumors. Alkylating agents such as cyclophosphamide (CYCLO) possess good activity in many of solid tumors, including brain tumors. Although Ifosfamide (IFOS), a structural congener of CYCLO, has been suggested to have greater activity in several tumors, its activity in brain tumors is uncertain. We conducted a phase II trial of every-other day IFOS (3 gm/M2/qod x 3) in 87 recurrent pediatric brain tumors. Responses were evaluable in 71 patients. Partial responses occurred in 1/6 patients with low grade astrocytoma, 1/16 with malignant glioma, 1/16 with medulloblastoma, 1/3 with pineoblastoma and 1/12 patients with ependymoma. No responses occurred among 10 patients with brain stem gliomas or 8 patients with other brain tumors. Despite the poor objective response rate, 23/71 patients were clinically and imaging stable for periods of 8-62 weeks. There was no relationship between prior CYCLO treatment and subsequent response or failure with IFOS. The predominant toxicity was myelosuppression. Although generally reversible, prolonged suppression and sepsis were responsible for the deaths of 3 heavily pretreated patients. Renal toxicity was uncommon; 2 patients had grade III, and one grade IV renal tubular dysfunction. One patient had grade IV hematuria. Neurotoxicity was less common than in studies of daily ifosfamide; only 1 patient had grade IV neurotoxicity. Three patients had grade III or IV IFOS related hyponatremia. Despite the good stable disease rate, the poor rate of objective response suggests that IFOS monotherapy possesses little clinically meaningful activity in brain tumors.

28 patients with recurrent advanced breast cancer were treated with a salvage regimen consisting of vincristine, epirubicin and ifosfamide/mesna (VIE). All patients had poor prognostic characteristics defined as relapse within 12 months of chemotherapy or as relapse within a radiotherapy field. Chemotherapy was infused continuously through a central venous catheter using a portable pump. Ifosfamide (3 g/m2) mixed with mesna (3 g/m2) was infused for 7 days followed by epirubicin (50 mg/m2) mixed with vincristine (1.5 mg/m2) over a further seven days and alternated for a total of 6 weeks. 9 of the 28 patients (32%) responded to VIE (six partial and three complete responses). This included 6 of the 18 patients (33%) who had previously received doxorubicin or mitoxantrone, 6 of the 17 patients (35%) who had an inoperable in-field relapse after radiotherapy for locally advanced cancer, and 5 of the 21 patients (24%) relapsing within 6 months of previous chemotherapy. Median duration of response and overall survival were 3.7 and 6.9 months, respectively. Myelotoxicity was mild. One patient had neutropenic sepsis, 3 patients ahd grade 3 nausea and vomiting and one patient developed paralytic ileus attributed to vincristine. Central venous catheter complications occurred in 12 of 33 catheters requiring removal in 6. Continuous infusional chemotherapy using vincristine, epirubicin and ifosfamide achieves a 32% overall response rate in treatment-resistant advanced breast cancer, and is associated with minimal toxicity and a short treatment period. VIE may be a suitable alternative to conventional chemotherapy.

Ifosfamide, carboplatin, cisplatin, etoposide, and paclitaxel are chemotherapeutic agents active in treating many malignant diseases. The ICE combination (ifosfamide/carboplatin [or cisplatin]/etoposide) has been studied in breast cancer, small cell and non-small cell lung cancer, testicular cancer, lymphoma, and other malignancies with promising results. We conducted a dose-escalation study of paclitaxel in combination with ICE (ICE-T) to evaluate the toxicity and define the maximum tolerated dose of paclitaxel. To date, 24 patients have been treated with ICE-T. Patients had to have no or minimal prior chemotherapy, an Eastern Cooperative Oncology Group performance status of 0 or 1, and adequate bone marrow, liver, and kidney function. The doses of ICE were as follows: ifosfamide 1.25 g/m2/d days 1 to 3, carboplatin 300 mg/m2 day 1, and etoposide 80 mg/m2/d days 1 to 3. Paclitaxel was given at a dose of 120 mg/m2 to five patients, 135 mg/m2 to five patients, 150 mg/m2 to three patients, and 175 mg/m2 to 11 patients. All patients received granulocyte colony-stimulating factor support. The most common side effect was neutropenia. Grade 4 neutropenia and thrombocytopenia occurred during 34% and 20% of 94 cycles, respectively, with leukopenic fever occurring during 14% of cycles. No treatment-related death or sepsis occurred due to brief nadir durations of 3.5 days for neutropenia and thrombocytopenia. Other toxicities were mostly mild to moderate and did not require dose modification, although alopecia was universal. Nine patients (100%) with metastatic breast cancer and four (67%) with soft tissue sarcoma have attained documented objective responses with four complete remissions (one breast cancer and three sarcoma patients). The maximum tolerated dose of paclitaxel has not yet been defined, and the study is ongoing. In conclusion, this pilot study showed that ICE-T is safe and tolerable. The response to ICE-T is encouraging and warrants further study with this regimen.

We conducted a phase II study of ifosfamide and etoposide chemotherapy in patients with untreated extensive-disease small-cell lung cancer to assess response and toxicity. Between January 1994 and December 1995, 16 patients were treated. Ifosfamide and etoposide doses were ifosfamide 2 g/m2, with mesna, i.v. infusion over 30 minutes on days 1-3 and etoposide 80 mg/m2 i.v. over 120 minutes on days 1-3 every 4 weeks for up to six cycles. All patients were evaluable for toxicity profile and treatment response. As expected, the major toxicity was myelosuppression. With one exception, grade 3 or 4 leukopenia occurred in all patients during treatment, and 48.7% of the total courses had grade 3 or 4 leukopenia. Nine of 16 patients (56.3%) experienced episodes of febrile neutropenia. One toxic death due to febrile neutropenia with sepsis was documented. Toxicities other than leukopenia were few and mild in severity. After two cycles of treatment, the overall response rate was 81.3% (95% confidence interval 62.2-100) in this study. The median duration of response was 8 months and median survival was 11 months. In conclusion, ifosfamide and etoposide is an active combination regimen with acceptable toxicity profile in Chinese patients with extensive-disease small-cell lung cancer.
