Hemato-oncology patients needing mechanical ventilation for acute respiratory failure (ARF) have an extremely poor prognosis, with a mortality of more than 90%. Over an 18 month-period 17 such patients were admitted to our ICU. Diagnoses included leukemia (11 cases), lymphoma (1), and status post bone marrow transplantation for leukemia, lymphoma or breast cancer (5). Of 8 whose ARF was associated with septic complications due to neutropenia following chemotherapy, 6 survived. Of 9 who developed ARF due to toxic damage to vital organs following high-dose chemotherapy, 2 survived. Those who develop ARF during chemotherapy are expected to have an increase in granulocyte count within days, and have a surprisingly good prognosis. They should be admitted to the ICU and treated aggressively. Those who develop sepsis due their primary disease and whose general condition contraindicates chemotherapy, have an extremely grave prognosis and admission to the ICU may not be warranted.

Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) is a highly active single agent in the treatment of breast cancer. However, its optimal incorporation into combination regimens awaits definition. We added paclitaxel, administered by 1-hour infusion, to a previously described combination regimen that included mitoxantrone, 5-fluorouracil, and high-dose leucovorin. Forty-six patients with metastatic breast cancer received the following regimen as first- or second-line treatment: paclitaxel 135 mg/m2 by 1-hour intravenous infusion on day 1; mitoxantrone 10 mg/m2 by intravenous bolus on day 1; 5-fluorouracil 350 mg/m2 by intravenous bolus on days 1, 2, and 3; and leucovorin 300 mg intravenous over 30 to 60 minutes, immediately preceding 5-fluorouracil on days 1, 2, and 3. Courses were administered at 3-week intervals for a total of eight courses in responding patients. Of 45 assessable patients, 23 (51%) had major responses. Previous chemotherapy, and in particular previous treatment with doxorubicin, did not affect response rate. The median response duration was 7.5 months. Myelosuppression was moderately severe, with 76% of courses resulting in grade 3 or 4 leukopenia. There were four treatment-related deaths, two sepsis, one congestive heart failure, and one sepsis and congestive heart failure, the last two after a large cumulative anthracycline dose. This combination regimen was active as first- or second-line therapy for metastatic breast cancer, although how its activity compares with that of other combination regimens or with paclitaxel alone is unclear. Myelosuppression was more severe than had been anticipated based on previous results with the mitoxantrone/5-fluorouracil/high-dose leucovorin regimen or with single-agent paclitaxel administered at this dose and schedule. The infrequent development of cardiotoxicity in these patients suggests that the paclitaxel/mitoxantrone combination may not share the problems previously reported with paclitaxel/doxorubicin combinations. We have embarked on a phase I/II trial of paclitaxel/mitoxantrone and have determined the maximum tolerated dose to be 200 mg/m2 and 10 mg/m2, respectively, without the use of cytokines. Fifteen patients have been treated at the maximum tolerated dose, and it is too early to assess results.

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.

Despite adjuvant chemotherapy the prognosis of patients with breast cancer and a high number of involved axillary lymph nodes is very poor. The aim of the present study was to evaluate the efficacy of high-dose chemotherapy with autologous bone marrow support in patients with seven or more involved axillary lymph nodes. Nineteen patients underwent four courses of standard adjuvant chemotherapy, followed by high-dose busulphan/cyclophosphamide chemotherapy with autologous bone marrow support. The median age was 41.4 years and the median number of involved lymph nodes 11. Mucositis WHO grade > or = 3 was observed in 15 patients and 18 patients suffered febrile neutropenia. Transplant-related mortality was encountered in two patients, due to hepatic veno-occlusive disease and sepsis complicated by multi-organ failure, respectively. After a median follow-up period of 1490 days (range 582-2024 days) from diagnosis, nine patients have relapsed and the overall event-free survival (EFS) is 42% (95% CI 19-65%). The median EFS is 487 days. High-dose treatment with BuCy2 in high-risk breast cancer patients is a toxic regimen and does not seem to improve disease-free survival.

Docetaxel is a new antimicrotubule agent that has been shown to be active against a variety of solid tumors. Ifosfamide is an alkylating drug that has demonstrated activity against non-small cell lung cancer, testicular cancer, breast cancer, and soft tissue sarcoma. This phase I study of the combination of these drugs was performed to assess the feasibility of using the two agents together, to determine the maximum tolerated dose and the side effects, and to propose a safe schedule for further phase II studies. Thirty-four patients with histologically confirmed solid tumors who had not been treated previously with taxanes or ifosfamide and who had received no more than one line of chemotherapy for advanced disease were entered into the study. Treatment consisted of docetaxel given as a 1-hour infusion followed by ifosfamide as a 24-hour infusion (schedule A), or ifosfamide followed by docetaxel (schedule B) every 3 weeks. Docetaxel doses ranged from 60 to 85 mg/m2 and ifosfamide doses from 2.5 to 5.0 g/m2. Grades 3 and 4 granulocytopenia were observed in 89% of courses and appeared to be of short duration and related to the ifosfamide dose. Febrile neutropenia and sepsis occurred in 17% and 2% of courses, respectively. Severe anemia and thrombocytopenia were uncommon. Nonhematologic toxicities were mild to moderate, and included alopecia, nausea, vomiting, mucositis, diarrhea, sensory neuropathy, skin and nail toxicity, hypersensitivity reactions, and edema. Schedule B appeared to induce more gastrointestinal toxicity than schedule A. One complete response in soft tissue sarcoma and two partial responses, one in cancer of unknown primary and the other in non-small cell lung cancer, were documented. The dose-limiting toxicity for schedule A was neutropenic fever at a dose of 85 mg/m2 docetaxel and 5 g/m2 ifosfamide. The dose-limiting toxicity for schedule B was neutropenic fever at a dose of 75 mg/m2 docetaxel and 4 g/m2 ifosfamide. A dose of 75 mg/m2 docetaxel combined with 5 g/m2 ifosfamide according to schedule A can be recommended for further studies.

We report long-term results of high-dose cyclophosphamide, etoposide and carboplatin with ABMT in 20 patients with metastatic breast cancer. Median age of the group was 41 years, ECOG performance status = 0 in 18 patients and 1 in two patients. Twelve patients had received adjuvant chemotherapy. Predominant sites of metastases were lung (eight), chest wall (four), liver (four), bone (three) and lymph nodes (three). Response to pretransplant chemotherapy was complete (CR) in four patients, partial (PR) in 10 patients and stable (SD) in five patients. After high-dose chemotherapy eight patients were in CR, six PR, four SD and one progressive disease. Two patients died of regimen-related toxicities (candidal sepsis and alveolar hemorrhage). With a median follow-up period of 55 months (minimum 48 months), 12 patients have died of recurrent breast cancer, one died of toxicity of salvage chemotherapy, two are alive with disease, two are alive and free of progressive disease. One patient with relapsed disease was lost to follow-up. Median event-free survival is 6 months and median overall survival is 17 months. All three of the long-term disease-free survivors had predominantly nodal disease. Two of these three patients presented with metastatic disease and received high-dose chemotherapy with ABMT as part of initial therapy for breast cancer; two of three attained CR to standard-dose cytoreductive therapy; none received doxorubicin-containing adjuvant chemotherapy.

Irradiation is known to cause temporary to permanent marrow aplasia in cancer patients when administered as a sole therapy or in combination with chemotherapy. Until now, no studies have been carried out evaluating the haematological toxicities of involved field radiation administered post autologous stem cell transplantation (ASCT). We assessed bone marrow (BM) toxicity in 93 patients who received involved field radiation post ASCT (non-Hodgkin's lymphoma 21, Hodgkin's disease 7, breast cancer 15, and other solid tumours 50. Severe BM toxicity, with grade IV neutropenia, and/or thrombocytopenia, and/or anaemia necessitating interruption of radiotherapy for more than a week, was observed in 11 patients (malignant lymphoma-8 of which 7 were NHL, and 1 HD, breast cancer-1, Wilm's tumour-1, Ewing's sarcoma-1). Patients with malignant lymphoma were at higher risk of developing post ASCT radiation-induced cytopenias than patients with breast cancer or solid tumours, 28% vs 4.5%, respectively (P < 0.05). Of the 11 patients, 7 developed bacterial sepsis and 10 were hospitalised. The radiation-induced cytopenia patients necessitated platelets and red blood cell transfusions, interrupting the course of irradiation. Of the patients suffering from non-Hodgkin's lymphoma, 8/14 (57%) of those who received conventional courses of radiotherapy relapsed compared to 6/7 (86%) of those who received interrupted radiotherapy (P < 0.05). The most appropriate timing for radiation in malignant lymphoma patients who are scheduled for ASCT, as well as the protective role of haematopoietic growth factors like erythropoietin and Granulocyte (G) or Granulocyte-Monocyte (GM), colony stimulating factors (CSF) and others, are discussed.

The purpose of this study was to evaluate the toxicity and activity of continuous infusional 5-fluorouracil (5-FU) given at three dose levels in combination with cyclophosphamide and doxorubicin (FAC) in women with breast cancer. Thirty-nine patients with either primary tumours >3 cm prior to surgery (n = 24) or metastatic disease (n = 15) received cyclophosphamide 600 mg/m2 and doxorubicin 50 mg/m2 as an intravenous bolus every 3 weeks for six courses. Continuous infusional 5-FU was delivered via a central venous line for a maximum of 18 weeks at dose levels of 100 mg/m2 per day (n = 6), 150 mg/m2 per day (n = 3) and 200 mg/m2 per day (n = 30). At the 200 mg/m2 per day dose level, 36% of patients required dose delays and 23% dose reductions; there was one death due to neutropenic sepsis. Hickman line complications occurred at all dose levels, particularly thrombosis (18%) and infection (33%). The response rate was 62% (95% confidence interval (CI) 32-84) for metastatic disease, including five complete responses (CRs). The response rate for primary tumours prior to surgery was 81% (95% CI 57-95) including six clinical CRs. Infusional FAC is an active regimen and has an acceptable toxicity profile. It does not, however, appear to offer any significant advantage over other chemotherapy regimens. This study does not support the further evaluation of infusional 5-FU at these doses in combination with doxorubicin and cyclophosphamide.

Dose-intensive chemotherapy appears to be important in the treatment of patients with recurrent solid tumors. Expanding upon our prior experience, we report the results of our most recent approach to administering dose-intensive therapy using four cycles of moderately high-dose chemotherapy with hematopoietic cell support for patients with metastatic breast cancer. This outpatient therapy includes high-dose melphalan, thiotepa, and paclitaxel for two cycles followed by mitoxantrone, thiotepa, and paclitaxel for two cycles, with each cycle supported with autologous peripheral blood progenitor cells (PBPCs). Between December 1994 and June 1996, 16 patients with recurrent or refractory breast cancer were enrolled in this prospective study. They had received a median of two previous chemotherapy regimens, with a median of nine prior cycles of chemotherapy. For mobilization of autologous PBPCs, patients received cyclophosphamide, 4 g/m2, followed by granulocyte colony-stimulating factor (G-CSF). PBPCs were collected by apheresis. Each day's collection was divided into four equal fractions, and each fraction was infused after each cycle of combination therapy. Cycles 1 and 2 consisted of melphalan, 80 mg/m2, thiotepa, 300 mg/m2, and paclitaxel, 200 mg/m2. Cycles 3 and 4 were comprised of mitoxantrone, 30 mg/m2, and thiotepa and paclitaxel at the same doses as in the first two cycles. The cyclophosphamide infusion was administered in the hospital, whereas all subsequent infusions of chemotherapy and PBPCs were performed on an outpatient basis. The first seven patients were randomized to receive alternate cycle G-CSF or placebo on day +1 of each cycle. Including the initial pulse of cyclophosphamide, 67 (84%) of a planned 80 total courses of chemotherapy were delivered. Of the planned 64 cycles of high-dose combination chemotherapy, 52 cycles (81%) were delivered. Treatment was discontinued for progressive disease (one patient) or morbidity (five patients). Twelve of 16 patients completed at least three cycles of therapy. Nine patients completed all four cycles. One death resulted from fungal sepsis. In 20 cycles delivered to the first seven patients, day +1 G-CSF versus placebo was administered, with a median WBC recovery of 10 versus 13 days, respectively (P = 0.048 in cycle 1). The median duration of response was almost 9 months, and the median survival was 18 months after therapy. With a median follow-up of 1.5 years and longest follow-up of 4.2 years, two patients continue to be without evidence of disease. The 3-year event-free survival, freedom from progression, and overall survival are 19%, 20%, and 31%, respectively. This four-cycle regimen of high-dose combination therapy supported with hematopoietic progenitor cells is feasible, but it is associated with a range of posttransplant complications. The efficacy of such a treatment would have to be substantially superior to that of other currently available therapies, including single autologous transplant procedures, to justify the prolonged period of treatment, multiple episodes of pancytopenia, and associated toxicities, including infectious risks. G-CSF administration after each PBPC infusion appears to accelerate time to neutrophil recovery but does not affect red cell or platelet engraftment.

Breast cancer patients who, following treatment with primary chemotherapy (FAC 50) present an axillary node involvement of more than 4 nodes together with clinically palpable residual disease (minor response to chemotherapy) and the presence of tumour cell emboli in lymphatics have a very poor outcome. DFS rates of 50 patients treated between 1990 and 1994 were 31% at 5 years. Our aim was therefore to evaluate an entirely different therapeutic regime in these very high risk patients. 32 patients selected for these criteria entered a pilot study consisting in treatment with 3 four weekly cycles of vinorelbine, ifosfamide, cisplatinum followed by a high dose chemotherapy (HDCT) course and rescue by peripheral hematopoietic stem cells which had been collected by cytapheresis after the second course of chemotherapy. HDCT consisted of thiotepa, L-Pam, CBDCA (800 mg/m(2) d1), ifosfamide and mesna. Following primary chemotherapy, 14 patients had breast conservation and 18 had a modified mastectomy. Median number of involved lymph nodes was 11 (range 4-26). 29 patients received the complete HDCT course. Median age was 40 (range 24-59). Engraftment was prompt with a median of 10 days to leucocyte recovery to 1,000/microl and 9 days to platelet recovery. One patient developed reversible renal failure, and subsequently died of Gram-septicemia. To date, with a median follow up of 20 months (range 14-36), 6 patients have relapsed and 2 patients have died. It is too early to make any firm conclusions, but we feel that this alternative regime is feasible and may prove superior to the classical optimal dose anthracycline-containing regimes in patients who have a tendency to rapidly develop resistance to anthracyclines.
