We have previously reported that the lethal toxicity of 5-fluorouracil (5-FU) in specific-pathogen-free mice is due to an intestinal infection with indigenous Escherichia coli induced by the drug (K. Nomoto, T. Yokokura, Y. Yoshikai, M. Mitsuyama, and K. Nomoto, Can J. Microbiol. 37:244-247, 1991). In the present study we demonstrate that nonspecific immunostimulation is effective in the protection of mice from the lethal indigenous infection induced by 5-FU. Intravenous or subcutaneous injection of a preparation of heat-killed Lactobacillus casei YIT 9018, a potent nonspecific immunostimulant, into BALB/c mice reduced the lethal toxicity of 5-FU at doses ranging from 338 to 800 mg/kg of body weight if YIT 9018 was injected 7 to 40 days before administration of 5-FU.
Systemic infection
with E. coli developed in all of the 5-FU-treated control mice 7 days or more after administration of 5-FU in large doses and was accompanied by overgrowth of the bacteria in the intestinal tract. Pretreatment of mice with YIT 9018 resulted in a decreased occurrence of systemic infection with E. coli to levels of 0 to 20% and no significant changes in the population levels of E. coli in the intestinal tract during the 14 days after administration of 5-FU. The levels of leukopenia in the spleen and peripheral blood were lower, and recovery of granulocyte-macrophage precursor cells in the spleen and femur began earlier in the treated animals than in the 5-FU-treated controls. Intravenous transfusion of syngeneic normal bone marrow cells or spleen cells into the mice at an early period after administration of 5-FU diminished markedly the occurrence of the lethal indigenous infection, suggestion that an earlier recovery from chemotherapy-induced
myelosuppression
is important in the mechanisms of protection of the host from the infection.

A total of 45 patients with advanced non-small-cell lung carcinoma were treated with a combination of cisplatin, teniposide, and mitomycin C. Most subjects exhibited good prognostic factors (performance status, 0-1; minimal weight loss; locoregional disease). Toxicity consisted mainly of
myelosuppression
and nausea and vomiting. Four patients died of
sepsis
due to chemotherapy-induced leukopenia. The response rate was 39.5%, with no complete responses being observed; the median duration of partial responses was 231 days and median survival was 243 days. Although the response rate and durations of both response and survival were comparable with those obtained using other cisplating-containing regimens, myelotoxicity was rather pronounced in the present study. Further studies of teniposide in this type of combination are not warranted.

In order to develop a more dose-intensive induction regimen for the treatment of far-advanced testicular tumours, the German Cooperative Group for Testicular Tumours started a dose-escalation trial of cisplatin, etoposide and ifosfamide. At the first dose level 18 patients with advanced testicular cancer (Indiana University classification) received cisplatin 25 mg/m2, etoposide 120-150 mg/m2 and ifosfamide 1.2 g/m2 for 5 days every 3 weeks. Of these, 13 patients (72%) became tumour-free, 2 achieved a stable, marker-negative partial remission, 2 had progressive disease and 1 patient died of Clostridium
sepsis
. The main toxicity was
myelosuppression
with a white blood cell nadir of 900/microliters and a thrombocyte nadir of 47,000/microliters. Granulocytopenic fever occurred in 43% of all cycles. At the second dose level 15 patients received cisplatin 30 mg/m2, etoposide 150 mg/m2 and ifosfamide 1.6 g/m2 five times every 3 weeks together with s.c. recombinant granulocyte/macrophage-colony-stimulating factor (GM-CSF) 10 micrograms/kg on days 6-15. Acute toxicity was severe with a white blood cell nadir of 300/microliters and thrombocyte nadir of 11,000/microliters. The duration of the thrombocytopenia increased with cycle number; 63% of all cycles were associated with granulocytopenic fever and in 83% platelet transfusions were required. One patient died from acute renal failure and Aspergillus
sepsis
; 3 patients experienced adverse reactions to GM-CSF, requiring omission of this drugs in 2; 33% had grade 3 or 4 mucositis. At this dose level 8 patients (53%) became tumour-free, 4 patients (26%) had marker normalization with irresectable residual disease and 2 patients were treatment failures. Though acute toxicity was severe at this dose level, there was no unexpected or unmanageable organ toxicity and thus patients are now entered at dose level 3, which consists of cisplatin 30 mg/m2, etoposide 200 mg/m2 and ifosfamide 1.6 g/m2 for 5 days and GM-CSF 10 micrograms kg-1 day-1 on days 6-15 s.c.

Taxol is a unique mitotic inhibitor that has entered phase II investigation. Phase I studies demonstrated hypersensitivity reactions that were related to the cremophor vehicle and to the rate of drug infusion. As a result, the time span of intravenous (IV) infusion of taxol was routinely prolonged to 6 hours or beyond, and premedication with diphenhydramine, dexamethasone, and cimetidine was initiated. Early studies showed antitumor activity, especially against malignant melanoma and ovarian carcinoma. This phase I trial was performed giving taxol, as a 6-hour IV infusion every 21 days, without premedication. The purpose was to study the necessity of premedication and its impact on toxicity and pharmacokinetics. Thirty-one patients received 64 assessable courses of taxol. One patient had a hypersensitivity reaction, which was easily controlled using routine measures.
Myelosuppression
was dose-limiting, but sporadic, with two fatalities due to
sepsis
. Nonhematologic toxicity was of grade 1 and 2 except for one patient with grade 3 mucositis and two patients with grade 3 neuropathy. The neuropathy consisted of reversible painful paresthesias, requiring discontinuation of drug in two patients. Four partial responses were seen (three in patients with non-small-cell lung cancer, one in a patient with adenocarcinoma of unknown primary). Pharmacokinetic values were consistent with those previously reported. The occurrence of
myelosuppression
or neurotoxicity appeared to be associated with the area under the concentration x time curve (AUC) of taxol. The recommended phase II starting dose on this schedule is 225 mg/m2. Taxol merits broad investigation at the phase II level.

Both cisplatin and leucovorin (LV) interact with fluorouracil (5-FU) by increasing intracellular reduced folate levels and thereby the inhibition of thymidylate synthase. Therefore, the addition of LV to cisplatin and 5-FU (PFL) may increase the activity of that combination in head and neck cancer. We treated 31 patients with locally advanced head and neck cancer with two cycles of neoadjuvant PFL consisting of 100 mg/m2 of cisplatin on day 1 followed by a 5-day continuous infusion of 5-FU at 1,000 mg/m2/day and oral LV at 100 mg administered every 4 hours during the entire duration of chemotherapy infusion. Two patients died during neoadjuvant chemotherapy of sudden death and
sepsis
, respectively, and were not evaluated for response. Of 29 evaluable patients, nine had a complete response (CR), 17 had a partial response (PR), and three had stable disease. Toxicities consisted of mild to moderate
myelosuppression
and moderate to severe mucositis, necessitating reduction of 5-FU on cycle 2 to less than or equal to 80% of the intended dose in 22 of 29 patients. Administration of LV by repeated oral dosing resulted in total reduced folate plasma concentrations of 5.3 (+/- 2.9) and 6.7 (+/- 3.4) mumol on days 2 and 4 of the 5-FU infusion. The sum of 1-LV and its metabolite 5-CH3-tetrahydrofolate exceeded the concentration of d-LV, consistent with selective absorption of the biologically active 1-stereoisomer from the gastrointestinal tract.

The synergism of combined high-dose etoposide with standard dose cisplatin (HD-EP) was evaluated in 20 patients who had relapsed after treatment of small cell lung cancer. Each patient was given etoposide at 500 mg/m2/day on days 1 to 3 and cisplatin at 80 mg/m2 (two patients given 120 mg/m2) on day 1; autologous bone marrow was not transplanted. Five patients were given recombinant human granulocyte colony-stimulating factor (rhG-CSF, 50 micrograms/m2) in an attempt to reduce HD-EP induced neutropenia. The overall response was 50% (9 of 18); one complete response (6%), eight partial responses (44%), seven no change (39%), and two progressions of disease (11%). Of the 18 evaluable patients, 12 had been treated with regimens of conventional doses of etoposide with conventional doses of cisplatin or carboplatin, and of these, five (42%) achieved a partial response. The median duration of response was 8.4 weeks (range, 5.3 to 17.7) and the median survival time was 20.3 weeks (range, 1.6 to 91). All of the patients developed severe
myelosuppression
; rhG-CSF did not shorten the period of the leukopenia. Mucositis and liver dysfunction were the major nonhematologic manifestations of toxicity. Two treatment-related deaths resulted from
sepsis
. These results suggest that the activities of high doses etoposide with standard doses of cisplatin are synergistic against small cell lung cancer.

Forty-four patients with relapsed or resistant Hodgkin's disease were treated with adriamycin 40 mg m-2 i.v. on day 1, vincristine 1.4 mg m-2 i.v. on days 1 and 8, prednisolone 40 mg m-2 orally daily for 8 days, etoposide 200 mg m-2 orally daily for 4 days according to the nadir white cell count, and bleomycin 10 mg m-2 i.v. days 1 and 8 (HOPE-Bleo). Median age was 27 (range 12-71). When stage was considered according to all sites currently or previously involved by Hodgkin's disease (cumulative stage) 26 patients (59%) had stage IV, 13 (29%) stage III and five (11%) stage II disease; 33 (75%) had B symptoms. All patients had received previous chemotherapy and 18 (41%) had received two or more regimens. Twenty-six patients (59%) achieved CR and 10 (23%) PR; the median duration of CR was 22 months and median survival for all patients was 48 months. Eight patients remain in continuous CR; none of these had received extensive previous chemotherapy. Among the 19 patients who had relapsed from CR achieved by a single previous chemotherapy regimen, six (32%) achieved long CR on HOPE-Bleo. The regimen was generally well tolerated but the principal toxicity was
myelosuppression
. There were two toxic deaths, one due to neutropenic
sepsis
and the other due to acute peritonitis. The HOPE-Bleo regimen is an effective treatment for relapsed or resistant Hodgkin's disease, with a low probability of carcinogenesis and infertility. These factors suggest that HOPE-Bleo deserves further evaluation as primary treatment for Hodgkin's disease and very careful selection of relapsed patients for high dose salvage chemotherapy with bone marrow transplants must be exercised.

The relation between degree of
myelosuppression
and episodes of infection was analyzed in 36 patients (92 treatment courses) with small cell lung cancer (SCLC) treated with intensive chemotherapy. The two regimens used were cisplatin (CDDP) + adriamycin (ADR) + cyclophosphamide (CPA) + etoposide (VP-16) + granulocyte-colony stimulating factor (G-CSF) and CDDP + teniposide (VM-26) + G-CSF, and they induced grade 3 or 4 leukopenia in 88% of treatment courses and febrile episodes in 60%. In the febrile courses, the mean nadirs of leukocyte and neutrophils (820 +/- 581/mm3, 101 +/- 267/mm3) were significantly longer (P less than 0.01) and the mean durations of grade 3 and 4 leukopenia and neutropenia significantly longer (P less than 0.001) than those of the non-febrile courses. It was noted, however, that febrile episodes appeared frequently in courses having the nadir of leukocytes below 1,000/mm3 (80%) or the nadir of neutrophils below 100/mm3 (74%). The administration of antibiotics was required for about 7 days to patients with febrile episodes.
Sepsis
was experienced in five courses, in which the neutrophils were all zero. All the patients, however, could be managed by an administration of antibiotics immediately after a febrile episode appeared, without delaying the subsequent chemotherapy except for one patient, who had had a performance status (PS) of 3 prior to chemotherapy.

An escalating-dose trial of idarubicin, used weekly for 3 doses in combination with vincristine, prednisone, and L-asparaginase (VPLI), to reinduce remission of childhood ALL at first bone marrow relapse was conducted by the Childrens Cancer Study Group (CCSG). The maximum tolerated dose (MTD) of idarubicin, used in the manner, was determined to be 12.5 mg/m2/dose. Twelve of 16 (75%) evaluable patients in first marrow relapse of ALL treated at a dose of 10 or 12.5 mg/m2 entered a second complete remission, compared to 41 of 69 evaluable patients (59%) treated in a comparable way with daunorubicin (30 mg/m2) (VPLD). Prolonged
myelosuppression
was observed in both groups, but the frequency of documented bacterial
sepsis
and the duration of required hospitalization were greater among patients treated with idarubicin. No additional toxicity, specifically attributable to idarubicin, was observed at these doses.

To study the efficiency of high-dose melphalan in previously untreated patients with advanced myeloma, we performed a Phase I-II trial. Twenty-eight patients were treated at dose level of 60-140 mg/m2. Each patient was first treated with a priming dose of cyclophosphamide (300 mg) followed by high-dose melphalen 1 week later. One course of therapy was given. Patients were then followed without further therapy until relapse. Clinical and laboratory features of the 28 patients in this study included: median age 63, performance status 0-2, hypercalcemia 21%, bone pain 82%, paraprotein types: IgG 76%, Iga 20%, and paraproteinuria 71%. Because none of the patients achieved complete remission (CR) at 60 mg/m2, despite life-threatening toxicity in all patients, the dose level was rapidly increased to 140 mg/m2, a dose previously reported to induce a high percentage of CR. At this dose, CR was achieved in only 1 of 11 patients (9%). This patient had multiple plasmacytomas without generalized bone marrow involvement. One additional patient at 100 mg/m2 achieved CR. Of the whole group, 12 achieved PR. Durations of remissions were generally short: CR 6.3 and 18+ months and PR 2.3-18 month, median 6.9 months. Life-threatening
myelosuppression
was universal with prolonged pancytopenia. Treatment-related deaths from
sepsis
were observed in 29% of patients. The median survival of the entire group was 15.6 months. Older patients in this trial did not tolerate high-dose melphalen therapy well; this resulted in a high proportion of toxic deaths and poor overall survival.
