Abstract
AIM We describe the feasibility of combining infusional 5-fluorouracil (5-FU) with intraoperative radiation therapy (IORT). METHODS Patients with surgically resectable locally advanced gastrointestinal cancers were treated concurrently during surgery with IORT and a 72 h infusion of 5-FU. Patients without previous external beam radiation therapy (EBRT) were subsequently treated with EBRT (40-50Gy) concurrent with a 21-day continuous infusion of 5-FU. Pancreatic, gastric, duodenal, ampullary, recurrent colorectal, and recurrent anal cancer were included. RESULTS During IORT/5-FU, no chemotherapy-related grade III or IV hematologic or gastrointestinal toxicity was noted. Post-surgical recovery or wound healing was not affected. One of nine patients who received post-operative radiation required a treatment break. During follow-up, there were more complications in patients with pelvic tumours, especially those with previous radiation. Nine patients have had local and/or local regional recurrences, two of these in the IORT field. CONCLUSIONS Treatment with a combination of IORT and 5-FU followed by EBRT and 5-FU is feasible. However, long-term complications may be increased in previously irradiated recurrent pelvic tumours.

Abstract
We assessed the feasibility and pharmacokinetics of high-dose infusional paclitaxel in combination with doxorubicin, cyclophosphamide, and peripheral blood progenitor cell rescue. Between October 1995 and June 1998, 63 patients with high-risk primary [stage II with >or= 10 axillary nodes involved, stage IIIA or stage IIIB inflammatory carcinoma (n = 53)] or with stage IV responsive breast cancer (n = 10) received paclitaxel 150-775 mg/m(2)infused over 24 hours, doxorubicin 165 mg/m(2)as a continuous infusion over 96 hours, and cyclophosphamide 100 mg kg(-1). There were no treatment-related deaths. Dose-limiting toxicity was reversible, predominantly sensory neuropathy following administration of paclitaxel at the 775 mg/m(2) dose level. Paclitaxel pharmacokinetics were non-linear at higher dose levels; higher paclitaxel dose level, AUC, and peak concentrations were associated with increased incidence of paraesthesias. No correlation between stomatitis, haematopoietic toxicities, and paclitaxel dose or pharmacokinetics was found. Kaplan-Meier estimates of 30-month event-free and overall survival for patients with primary breast carcinoma are 65% (95% CI; 51-83%) and 77% (95% CI; 64-93%). Paclitaxel up to 725 mg/m(2) infused over 24 hours in combination with with doxorubicin 165 mg/m(2) and cyclophosphamide 100 mg kg(-1) is tolerable. A randomized study testing this regimen against high-dose carboplatin, thiotepa and cyclophosphamide (STAMP V) is currently ongoing.

Abstract
PURPOSE In recognition of the variety of available chemotherapeutic modulating agents and their potential to enhance the efficacy of platinum-based therapy, we embarked upon a phase I study to investigate the feasibility of combining fixed doses of carboplatinum (CBDCA) and etoposide (VP-16) with 24-h concurrent infusions of dipyridamole (DP), prochlorperazine (PCZ) and cyclosporine A (CSA) administered in escalating doses. METHODS Patients received intravenous VP-16 (200 mg/m2) and CBDCA (300 mg/m2), each over 30 min, starting at hour 6 of the modulator infusions. Resistance modulators were escalated sequentially to determine their respective maximally tolerated doses (MTDs). The pharmacokinetics (PK) of VP-16, CBDCA, and the three drug resistance (DR) modifiers were studied in eight patients. RESULTS A total of 59 patients were entered on study. The MTD was established at DP 5 mg/kg per day, PCZ 24 mg/h, and CSA 9.5 mg/kg per day. Dose-limiting toxicities included hypotension and severe sedation, presumably related to PCZ. No objective responses were seen. PK studies were performed when PCZ and DP doses were 24 mg/h and 3.3 mg/kg, and the CSA dose was either 8.5 mg/kg (five patients) or 9.5 mg/kg (three patients). The median clearance of VP-16 was 0.96 l/h per m2 (range 0.8-1.5 l/h per m2), which is lower than for VP-16 alone and similar to previously reported effects of CSA on VP-16 elimination. The median measured CBDCA AUC was 3.0 mg/ml x min (range 2.4-4.8 mg/ml x min). CBDCA AUC predicted by the Calvert formula using measured creatinine clearance underestimated the actual AUC in seven of the eight patients, in one case by as much as twofold. The median end of infusion PCZ and total DP plasma concentrations were 1.2 microM (range 0.5-2.2 microM) and 4.4 microM (range 1.3-5.9 microM), respectively, consistent with in vitro resistance modulatory levels. However, free DP was only 0.02 microM (range 0.004-0.04 microM). The median CSA level at 24 h of 1450 microg/l (range 1075-1640 microg/l) is in agreement with concentrations required for partial DR reversal in vitro, although it is much lower than levels achieved in our previous phase I study of CBDCA + CSA alone using similar doses of CSA. The CSA dose on the current trial was escalated beyond the MTD for the previous phase I study, suggesting that there may be an interaction between CSA and one of the other modulators. CONCLUSION These results demonstrate that in vitro DR-reversing levels of two of the three agents used in this study can be achieved in vivo, and that this combination of DR modulators has significant effects on the pharmacokinetics of VP-16.

Abstract
PURPOSE To evaluate the pharmacokinetics and toxicity of high-dose intravenous (i.v.) methotrexate (MTX) with leucovorin in patients with meningeal carcinomatosis. METHODS Of 16 eligible patients entered on this study, 13 with meningeal carcinomatosis from breast cancer, lung cancer, or osteosarcoma were treated with MTX at loading doses of 200-1500 mg/m2, followed by a 23-h infusion of 800-6000 mg/m2. Three patients without meningeal disease were also treated and the cerebrospinal fluid (CSF) MTX concentrations were compared in patients with and without central nervous system (CNS) disease. RESULTS Patients without CNS disease had lower CSF MTX concentrations relative to the plasma MTX levels than those with CNS disease, who all had CSF MTX concentrations above the target cytotoxic concentration (1 microM). The CSF MTX concentrations correlated better with the free and the total plasma MTX concentrations than with the doses. The mean half-life of CSF MTX was 8.7 +/- 3.4 h. The mean plasma clearance of MTX was not significantly different in patients with CNS disease (84 +/- 41 ml/min per m2) versus without CNS disease (59 +/- 38 ml/min per m2). All toxicities were grade 2 or less except grade 3 hematologic toxicity. No patient had an objective response in the CSF. CONCLUSION This trial demonstrates that potentially cytotoxic CSF MTX concentrations (> 1 microM) are delivered safely by i.v. infusion, a less invasive and better distributed CSF therapy compared with intrathecal MTX. Because of the excellent pharmacokinetics and toxicity, high-dose i.v. MTX should be evaluated at a loading dose of 700 mg/m2 and a 23-h infusion of 2800 mg/m2 with leucovorin in less heavily pretreated patients with carcinomatous meningitis.

Abstract
Oral transmucosal fentanyl citrate (OTFC) is a novel opioid formulation in which the potent synthetic mu-agonist fentanyl is embedded in a sweetened matrix that is dissolved in the mouth. It is undergoing investigation as a treatment for cancer-related breakthrough pain, a prevalent phenomenon defined as a transitory flare of moderate to severe pain that interrupts otherwise controlled persistent pain. There have been no controlled trials of other treatments for this condition. To evaluate the safety and efficacy of ascending doses of OTFC, a novel controlled dose titration methodology was developed that applied blinding and randomization procedures to the evaluation of recurrent pains in the home environment. The study was a multicenter, randomized, double-blind dose titration study in ambulatory cancer patients. The sample comprised adult patients receiving a scheduled oral opioid regimen equivalent to 60-1000 mg oral morphine per day, who were experiencing at least one episode per day of breakthrough pain and had achieved at least partial relief of this pain by use of an oral opioid rescue dose. After collection of 2 days of baseline data concerning the efficacy of the usual rescue drug, patients were randomly treated with either 200 or 400 microg OTFC unit doses in double-blind fashion. Up to two breakthrough pains each day could be treated with up to four OTFC unit doses per pain. OTFC in unit doses containing 200, 400, 600, 800, 1200 or 1600 microg of fentanyl citrate were available for the study. The unit dose was titrated upward in steps until the patient had 2 consecutive days on which breakthrough pain could be treated with the single unit dose, titration was ineffective at a 1600 microg unit dose, or 20 days elapsed. To maintain the double-blind, orders to titrate up were ignored one-third of the time according to a pre-defined randomization schedule accessible only to an unblinded study pharmacist. Main outcome measures included, numeric or categorical measures of pain intensity, pain relief, and global assessment of drug performance. Dose response relationships were found suggesting that the methodology was sensitive to opioid effects. Seventy-four percent of patients were successfully titrated. There was no relationship between the total daily dose of the fixed schedule opioid regimen and the dose of OTFC required to manage the breakthrough pain. Although the study was not designed to provide a definitive comparison between OTFC and the usual rescue drug, exploratory analyses found that OTFC provided significantly greater analgesic effect at 15, 30 and 60 min, and a more rapid onset of effect, than the usual rescue drug. Adverse effects of the OTFC were typically opioid-related, specifically somnolence, nausea and dizziness. Very few adverse events were severe or serious. This study demonstrated the feasibility of controlled trial methodology in studies of breakthrough pain. OTFC appears to be a safe and effective therapy for breakthrough pain, and dose titration can usually identify a unit dose capable of providing adequate analgesia. If the lack of a relationship between the effective OTFC dose and fixed schedule opioid regimen is confirmed, dose titration may be needed in the clinical use of this formulation. Further investigation of OTFC as a specific treatment for breakthrough pain is warranted.

Abstract
A group of 18 patients with advanced cancer were entered on a phase I study of a 120-h continuous intravenous infusion of hydroxyurea. The dose of hydroxyurea was escalated in cohorts of patients from 1 to 2 to 3.2 g/ m2 per day. The primary dose-limiting toxicity was neutropenia, often accompanied by leukopenia, thrombocytopenia and generalized skin rash. Prophylactic treatment of patients with dexamethasone and diphenhydramine hydrochloride prevented the skin rash, but not the hematopoietic toxicities. The pharmacokinetics of hydroxyurea were studied in all patients. The steady-state concentrations of hydroxyurea were linearly correlated with the dose (R2 = 0.71, n = 18, P < 0.0001). The mean +/- SE concentrations were 93 +/- 16, 230 +/- 6 and 302 +/- 27 microM at 1, 2 and 3.2 g/m2 per day, respectively. The mean +/- SE renal and nonrenal clearances of hydroxyurea were 2.14 +/- 0.18 and 3.39 +/- 0.28 l/h per m2 (n = 16), neither of which correlated with the dose. The concentration of hydroxyurea in plasma decayed monoexponentially with a mean +/- SE half-life of 3.25 +/- 0.18 h (n = 17). The steady-state concentration of hydroxyurea was > 200 microM in all nine patients treated at 2 g/m2 per day, a dose which was well tolerated for 5 days. We recommend this dose for phase II trials in combination with other antineoplastic agents.

Abstract
PURPOSE To evaluate the protective effect of low-dose dopamine given as continuous infusion in patients who undergo chemotherapy with the nephrotoxin cisplatin. PATIENTS AND METHODS Forty-two patients who received high-dose cisplatin-containing chemotherapy entered a prospective, randomized, double-blind, placebo-controlled trial. Twenty-one patients received dopamine, and 21 received placebo. Patients were to receive either infusional dopamine 2 micrograms/kg/min over 48 hours or placebo. Cisplatin 125 mg/m2 was administered 12 hours after initiating dopamine (group D) or placebo (group P). This schedule was repeated twice, 1 week apart. Measurements of serum creatinine, urinary electrolytes and creatinine, urinary excretion of epidermal growth factor (EGF), ototoxicity, parameters of hematopoietic recovery, and duration of hospitalization were analyzed. RESULTS We observed an increase in serum creatinine level to a peak of 1.9 mg/dL (range, 0.8 to 7.8) in the dopamine group, in comparison to 1.4 mg/dL (range, 0.9 to 3.3) in the placebo group (P = .04). Urinary magnesium excretion increased and EGF excretion decreased in both groups. Urinary sodium, chloride, and potassium excretion were increased in both groups, but more so in the placebo group. Dopamine had no measurable effect on hearing loss, duration of hospitalization, or hematopoietic recovery. CONCLUSION The use of prophylactic dopamine increased peak serum creatinine levels relative to placebo and failed to prevent cisplatin-induced renal toxicity or ototoxicity. Determination of whether dopamine could reverse chemotherapy-induced renal damage would require a randomized prospective trial.

Abstract
A phase I study of mitomycin C with menadione (2-methyl-1,4-naphthoquinone, a vitamin K analogue which lowers intracellular pools of reduced glutathione) was designed as an approach to overcoming tumor cell resistance to alkylating agent chemotherapy. Patients with refractory solid tumors (n = 51) were treated with a 48-h continuous intravenous infusion of menadione followed by a bolus intravenous dose of mitomycin C at the completion of the menadione infusion. Initial menadione doses of 8.0 and 4.0 g/m2 over 48 h were associated with hemolysis, so subsequent dose levels of menadione ranged from 1.0 to 3.0 g/m2 with mitomycin C from 5 to 20 mg/m2. All three patients treated with menadione at 8.0 g/m2 and the single patient treated at 4.0 g/m2 with mitomycin C at 5 mg/m2 developed clinically significant hemolysis despite the presence of red blood cell glucose-6-phosphate dehydrogenase. Subsequently, a revised escalation scheme for menadione was used, and all patients tolerated menadione doses of 1-2.5 g/m2 over 48 h with mitomycin C doses up to 20 mg/m2. Since the 3.0 g/m2 dose of menadione was associated with mild hemolysis in three of four patients, the maximum tolerated dose of menadione was established at 2.5 g/m2. All of the mitomycin dose levels were tolerated without unexpected toxicities attributable to the combination. Prolonged infusions of menadione at doses which have been associated with lowering of intracellular glutathione pools in short-term exposure are limited by dose-dependent hemolysis, probably due to depletion of erythrocyte glutathione by menadione-related redox cycling. There was no detectable deleterious effect of pre-exposure to menadione on mitomycin C tolerance. We recommend a combination of menadione at 2.5 g/m2 as a continuous intravenous infusion and mitomycin C at 15 mg/m2 for further study in solid tumors, for which treatment with single-agent mitomycin C is appropriate.

Abstract
The use of leucovorin to modulate 5-fluorouracil (FUra)-mediated inhibition of thymidylate synthase has been shown both in vitro and in vivo to improve the antitumor activity of FUra. Based on the activity of this combination in previously untreated patients, we performed a study of FUra and high-dose leucovorin (HDFA) in patients with metastatic breast cancer and minimal prior chemotherapy. Patients were stratified by prior chemotherapy (or relapse within 12 months of completing adjuvant chemotherapy) versus no prior chemotherapy (or relapse at greater than 12 months since completion of adjuvant chemotherapy). FUra was given daily for 5 days at 370 mg/m2/day with HDFA, 500 mg/m2/day, beginning 24 hours before and continuing 12 hours beyond the first and last FUra doses, respectively. Two objective responses occurred among 21 patients in the pretreated group (10%; 95% confidence interval: 1-30%). Four of 36 eligible patients (11%) in the "no prior therapy group" had complete responses (95% confidence interval: 3-26%). The major toxicities were moderate leucopenia and mucositis. We conclude that FUra plus leucovorin has modest antitumor activity in metastatic breast cancer.

Abstract
BACKGROUND Chemotherapy with a doxorubicin-containing regimen results in high overall response rates in the treatment of metastatic adenocarcinoma of the breast; the combination of doxorubicin, etoposide, and cyclophosphamide has produced a response rate of 84% in untreated patients with stage IV disease. Recent data suggest that selected groups of patients with metastatic disease treated with high-dose chemotherapy and stem cell support may enjoy unmaintained, long-term remission. This study was designed to establish the feasibility of administering the combination of high-dose infusional doxorubicin, etoposide, and cyclophosphamide followed by autologous stem cell rescue in patients with responsive metastatic, or high-risk primary breast cancer. METHODS Criteria for patient enrollment included the presence of high-risk primary breast cancer (stage II with > or = 10 involved axillary nodes or stages III A or B) or stage IV disease in complete or partial response; Karnofsky performance status of 80% or more; no prior radiation therapy to the left side of the chest; exposure to a 150-mg/m2 or smaller cumulative dose of doxorubicin, and a ventricular ejection fraction of 55% or more. Chemotherapy consisted of escalating doses of doxorubicin given by a 96-hour continuous intravenous infusion, followed by 60 mg/kg of etoposide and 100 mg/kg cyclophosphamide, both given intravenously. On Day 0, autologous bone marrow with or without peripheral stem cells, or granulocyte colony-stimulating factor primed peripheral stem cells alone were reinfused. RESULTS Thirty-five patients were treated in this study. There were no treatment-related deaths. No patient had a decrease in cardiac ejection fraction below 50% as a consequence of high-dose chemotherapy. Two patients suffered grade 3 mucositis at the highest level of doxorubicin (200 mg/m2). Of 21 patients treated for primary high-risk breast cancer, 19 are recurrence free, with a median follow-up of more than 8 months (> or = 4-36 months). Five of fourteen patients with stage IV disease remain progression free at greater than or equal to 5, 7, 9, 15, and 42 months. For patients with stage IV breast cancer, the median progression-free survival after high-dose chemotherapy was 9 months; the median overall survival had been reached at 22 months. CONCLUSIONS The phase II dose of doxorubicin in this combination therapy has been established at 165 mg/m2, with dose-limiting toxicity defined as mucositis. Further trials to define the role of this safe and effective high-intensity regimen in the treatment of breast cancer are indicated.

Abstract
Fluorodeoxyuridine (FUdR), the deoxynucleoside metabolite of 5-fluorouracil (5-FU), can be converted in a single step to fluorodeoxyuridine monophosphate (FdUMP), which binds covalently to thymidylate synthase (TS). Ribonucleotide reductase, an obligatory enzyme in the synthesis of deoxynucleotides, can be inhibited by hydroxyurea. Recognizing the well-established synergism between 5-FU and folinic acid (leucovorin), we hypothesized that the simultaneous administration of FUdR, leucovorin, and hydroxyurea might afford more effective inhibition of TS. Thirty-six patients with neoplastic disease considered refractory to standard therapy were entered into this phase I protocol. Treatment was administered on days 1 through 5 of a 28-day cycle and consisted of folinic acid (500 mg m-2 day-1) and FUdR at escalating doses of 0.1, 0.15, or 0.2 mg kg-1 day-1 both administered by continuous i.v. infusion, and hydroxyurea given p.o. once per day at doses ranging from 0 to 250o mg in 500-mg increments. The hydroxyurea and FUdR levels were escalated in a sequential fashion. The majority of patients had refractory breast or lung cancer. Dose-limiting toxicities were mucositis and diarrhea at the maximally tolerated dose of 0.15 mg/kg FUdR and 2000 mg hydroxyurea per day in conjunction with high-dose folinic acid. Hematological toxicity was minor. Of the 18 patients in whom response could be evaluated, none had evidence of objective disease regression. Mucositis and diarrhea are the dose-limiting toxicities when continuous infusions of FUdR and high-dose folinic acid are combined with oral hydroxyurea, effects that are consistent with the observed toxicities for FUdR when administered alone or in combination with leucovorin.

Abstract
BACKGROUND This study was designed to establish the feasibility of combining high-dose cisplatin, etoposide, and cyclophosphamide followed by stem cell rescue in patients with responsive metastatic or high-risk primary breast cancer. METHODS Eligibility criteria included the presence of high-risk primary breast cancer (Stage II with 10 or more involved axillary nodes or Stage IIIA or B) or Stage IV disease in complete or partial response; physiologic age 50 years or younger; Karnofsky performance status of 80% or greater; and creatinine clearance of 80 ml/minute or greater. Chemotherapy consisted of escalating doses of cisplatin (50-150 mg/m2 intravenously [IV]) given on days -12 and -5, etoposide (30 mg/kg IV) given on days -12 and -5, and cyclophosphamide (100 mg/kg IV) on day -3. On day 0, autologous bone marrow with or without peripheral stem cells, or granulocyte colony-stimulating factor primed peripheral stem cells alone were reinfused. RESULTS Thirty patients were enrolled in this study. Twenty-eight patients demonstrated no evidence of persistent renal damage after treatment. Two patients suffered symptomatic peripheral neuropathy, and one patient required a hearing aid 3 months after therapy. Hematopoietic toxicities were acceptable. There were two fatalities; Streptococcus viridans bacteremia and adult respiratory distress syndrome developed in one patient; and one patient who received 262 mg/m2 of cisplatin died of renal failure. Twelve of 18 assessable patients with Stage IV disease are without evidence of progression; 3 of these patients are progression-free at 11+, 12+, and 32+ months. With a median follow-up of 16+ months (range, 4-31 months), 7 patients of the group of 11 treated with high-risk primary breast cancer are without evidence of disease. CONCLUSIONS The Phase II dose of cisplatin when given on a day -12 and day -5 schedule in combination with etoposide and cyclophosphamide has been established at a total of 250 mg/m2. Dose-limiting toxicity has been defined as renal failure, and response rates were comparable to previously reported high-dose chemotherapeutic regimens.

Abstract
PURPOSE The use of leucovorin (LV) to modulate fluorouracil (FU)-mediated inhibition of thymidylate synthase has been shown both in vitro and in vivo to improve the antitumor activity of this drug. Based on our previous demonstration that this combination was active in heavily pretreated patients with prior FU exposure, we performed a phase II study of FU and high-dose intravenous calcium LV in patients with advanced breast cancer who had been exposed to no more than one prior chemotherapy regimen. PATIENTS AND METHODS Fifty-one female patients with metastatic breast cancer were entered onto this trial. Patients with metastatic disease limited to soft tissue, lymph nodes, skin, and pulmonary nodules were allowed no prior chemotherapy for advanced disease. Those with metastases in the liver or a lymphangitic pattern on chest x-ray were allowed either a single prior regimen for advanced disease or no therapy for metastatic disease if less than 1 year had elapsed since the completion of adjuvant chemotherapy. FU was given daily for 5 days at 400 mg/m2/d with calcium LV, 500 mg/m2/d, beginning 24 hours before and continuing 12 hours after the first and last FU doses, respectively. RESULTS The overall objective response rate among 45 eligible patients was 36% (95% confidence interval, 22% to 51%). Fourteen of 31 patients in the soft tissue category responded (45%), and two of 14 in the visceral category experienced an objective response (14%). The median response duration was 5 months. Toxicities were moderate leukopenia and mucositis. CONCLUSIONS FU plus LV is an active first-line regimen with antitumor efficacy comparable to that of the anthracyclines, which warrants further exploration in combination with other agents active in advanced breast cancer. FU plus LV in this schedule is also an excellent alternative for patients with medical contraindications to more intensive combination chemotherapy regimens.

Abstract
Twenty-seven patients with advanced cancer were entered in a phase I study of bolus i.v. 5-fluorouracil at a dose of 370 mg/m2/day for 5 days combined with a continuous i.v. infusion of (6S)-folinic acid for 5.5 days, starting 24 h in advance of the first 5-fluorouracil dose. The dose of (6S)-folinic acid was escalated in cohorts of patients from 250 mg/m2/day to a maximum of 1000 mg/m2/day. The pharmacokinetics of (6S)-folinic acid were studied in the 3 patients given 250 mg/m2/day and in 6 patients given 1000 mg/m2/day. The mean steady-state plasma concentrations of (6S)-folinic acid and its principal metabolite (6S)-5-methyltetrahydrofolate at the 250 mg/m2/day dose were 2.7 and 5.1 microM, respectively. Both concentrations were comparable to the concentrations produced when (6S)-folinic acid was administered as half of a (6R,S)-folinic acid mixture (E. M. Newman et al., Cancer Res., 49:5755-5760, 1989). At the 1000 mg/m2/day dose of (6S)-folinic acid, the concentration of (6S)-folinic acid was 15.3 microM, more than the 4-fold increase predicted by linear pharmacokinetics, while the concentration of (6S)-5-methyltetrahydrofolate was only 16.5 microM. The change in the ratio of the parent compound to its metabolite was accounted for by a decrease in the nonrenal clearance of (6S)-folinic acid, probably indicating saturation of its metabolism. The toxicities observed in this phase I trial, including stomatitis, diarrhea, neutropenia, and anemia, did not differ in nature or severity from those produced by 5-fluorouracil and (6R,S)-folinic acid when administered on the same schedule. Finally, the degree of toxicity did not appear to depend on the dose of (6S)-folinic acid over the range of doses tested.

Abstract
Fluorodeoxyuridine (FUdR) interferes with cellular metabolism by inhibiting thymidylate synthase. Therefore, we sought to modulate its activity with leucovorin (LV) and to identify the maximally tolerated dose given as a 5-day continuous intravenous infusion in combination with oral administration of LV at a dose of 100 mg every hour for four doses immediately preceding the start of the FUdR infusion and then every 4 h for the entire duration of FUdR treatment. Patients were evaluated at six FUdR dose levels ranging from 0.1 to 0.375 mg/kg per day. Severe or life-threatening mucositis was first observed in two of six patients treated at 0.25 mg/kg daily. Further escalation of the dose to 0.3 mg/kg per day resulted in grade 2 mucositis in four of six patients and in grade 3 mucositis in two cases. A dose of 0.375 mg/kg daily resulted in grade 3 toxicity in all three patients treated. Other types of toxicities included skin rash and hand-foot syndrome, but no hematologic toxicities were observed. Stable disease was observed in 11 of 24 evaluable patients, including 3 subjects with renal cell carcinoma. Our recommended dose for phase II trials is 0.3 mg/kg FUdR per day.

Abstract
A pilot study was performed to evaluate the feasibility of administering prolonged continuous infusion 5-fluorouracil with multiple bolus chemotherapeutic agents. Twelve patients with advanced measurable gastric carcinoma were treated with a combination chemotherapy program of continuous infusion 5-fluorouracil, bolus Adriamycin, mitomycin C, and low-dose cisplatin (FAMP). Responses were observed in 5 patients (2 complete and 3 partial). Observed toxicities included leukopenia, thrombocytopenia, mucositis, and hand-foot syndrome. Although the FAMP regimen has activity in advanced gastric carcinoma, the number of patients evaluated was small and significant improvement over currently available regimens could not be demonstrated. Evaluation of toxicities indicates that bolus administration of multiple agents (specifically, Adriamycin, mitomycin C, and cisplatin) can be used in conjunction with continuously infused 5-fluorouracil without excessive toxicity.

Abstract
Interstitial pneumonitis and biopsy-proven pulmonary fibrosis developed in a 35-year-old man with acute myeloblastic leukemia 4 months after conditioning with total body irradiation, etoposide and cyclophosphamide and allogeneic marrow transplantation from an HLA-identical sister. The patient had no evidence of graft-versus-host disease. Under treatment with cyclosporine and prednisone the patient became asymptomatic and radiographic changes of the chest normalized. Following discontinuation of immunosuppressive treatment the patient again became dyspneic, and chest radiographs showed bilateral diffuse interstitial infiltrates. Concurrently there was a rise in serum transaminases. Treatment with prednisone again resulted in resolution of all symptoms and normalization of radiographic and hepatic function abnormalities. This case indicates that late onset interstitial pneumonitis may respond to immunosuppressive therapy. Conceivably, such pulmonary disease may represent the first or only manifestation of chronic graft-versus-host disease.
