Abstract
A total of 18 patients with hepatocellular carcinoma (HCC) were treated by transcatheter arterial embolization (TAE) with a 4'-epi-doxorubicin (EDX)-lipiodol emulsion. Infusion of the EDX-lipiodol emulsion (EDX-L) via the hepatic artery was followed by the injection of gelatin sponge in 12 cases. The response and survival of these 12 patients following EDX-L treatment were compared with those of 42 subjects treated with a doxorubicin-lipiodol emulsion (DX-L) and those of 23 patients treated by TAE with gelatin sponge (GS) only. In the group treated with EDX-L, nine cases were AFP-positive in sera and four showed a decrease in serum AFP values to less than 10% of the pretreatment level. Seven cases showed a partial response, and nine cases showed no change in the size of the tumor. In the group treated with EDX-L, nine cases are alive, and the oldest has survived for more than 431 days since the treatment. The half-year survival value was 57%, and the 1-year survival value was 49%. These values did not differ significantly from those calculated for the group treated with DX-L. The 1-year survival value determined for patients treated with a lipiodol emulsion (EDX-L or DX-L) followed by GS was 65%, and the 2-year survival value was 39%. These results rates are significantly better than those obtained in patients treated with GS only (1-year survival, 39%; 2-year survival, 13%.

Abstract
A total of 30 patients presenting with inoperable hepatocellular carcinoma (HCC) were treated with intrahepatic arterial Lipiodol (5 ml) and 4'-epidoxorubicin (90 mg/m2) once every 4 weeks. The treatment results included no complete response, 2 partial responses, 6 cases of static disease and 19 cases of progressive disease. The median survival was 18.9 weeks. All patients had died by the time of this writing, with survival duration ranging from 4.1 to 87.3 weeks. Toxicities were minimal and included anaemia and alopecia. As compared with a historic control group that had received the same dose of intravenous 4'-epidoxorubicin, the treatment group showed similar response rates but developed fewer toxicities. There was no significant survival benefit over the control group. We concluded that although this form of treatment had comparable activity and produced fewer side effects, it provided no survival benefit over intravenous treatment. The slight prolongation of survival achieved in the treatment group as compared with the control arm might have been due to case selection.

Abstract
Patients (n = 174) with metastatic breast cancer previously untreated with anthracycline cytotoxic agents were randomized into two groups: Group 1 received FEC (5-fluorouracil 500 mg/m2, epirubicin 60 mg/m2 and cyclophosphamide 500 mg/m2) once every fourth week and group 2 received the treatment once weekly in the same monthly dosage. Treatment was recommended to continue until disease progression or to a cumulative epirubicin dose of 1,000 mg/m2, but could be discontinued at any time at the patient's request or at the treating physician's judgement. An interim analysis was made when 131 patients were evaluable for response, and 128 patients for toxicity. Hematological toxicity was significantly more severe in the monthly group, as was nausea and vomiting. Of the monthly treated patients 76% had total alopecia compared to 14% in the weekly group. There were no statistically significant differences in the occurrence of mucositis. Monthly FEC gave significantly higher response rate than weekly treatment (52 vs 34%, p = 0.01). Time to progression was significantly (p = 0.004) longer with monthly FEC. Patients in the monthly treated group lived significantly (p = 0.02) longer than patients in the weekly group. These results indicate that both toxicity and efficacy of epirubicin-containing combination therapy in breast cancer is dependent on the treatment schedule, not merely on dosage. Both efficacy and toxicity increased when the treatment was given once monthly compared to the weekly schedule.

Abstract
Anthracyclines are important antitumor agents used in the treatment of solid tumors, lymphomas, and acute lymphoblastic as well as myelocytic leukemias. The clinical utility of agents such as doxorubicin and daunorubicin and their well-characterized cardiotoxicity have prompted many efforts to develop analogs that retain the desired spectrum of activity but are less cardiotoxic. One such analog is idarubicin (4-demethoxydaunorubicin), which is currently under study in the treatment of adult and pediatric leukemias. The major circulating metabolite of idarubicin is the alcohol product of ketoreductase biotransformation, idarubicinol. Following the administration of idarubicin to adult or pediatric patients, systemic exposure to idarubicinol is greater than that to idarubicin. Moreover, we have also documented the presence of idarubicinol in the cerebrospinal fluid of pediatric patients who have received idarubicin. Idarubicinol has been reported to have greater cytotoxic activity than other anthracycline alcohol metabolites, which are regarded as much less active products of metabolism. We therefore evaluated the growth-inhibitory and DNA-damaging activities of idarubicin, daunorubicin, doxorubicin, epirubicin, and their alcohol metabolites against three relevant (CCRF-CEM lymphoblastic leukemia, K562 myelogenous leukemia, and U87-MG glioblastoma) human tumor cell lines. We found that whereas idarubicin was 2-5 times more potent than the other three anthracycline analogs against these tumor cell lines, idarubicinol was 16-122 times more active than the other alcohol metabolites against the same three cell lines. In addition, idarubicinol and the parent drug idarubicin were equipotent, unlike the other anthracycline alcohol metabolites, which were much less cytotoxic than the corresponding parent drugs. We also assessed the ability of the four parent drugs and their alcohol metabolites to induce DNA single-strand breaks. Idarubicin was more potent than the other three anthracycline analogs and idarubicinol was much more effective than the other alcohol metabolites in inducing DNA damage. These studies in human leukemia and human glioblastoma cell lines support the hypothesis that idarubicinol plays an important role in the antitumor activity of idarubicin and that the activities of idarubicin and idarubicinol are related to their ability to damage DNA.

Abstract
One hundred and eleven previously untreated patients with extensive small cell lung cancer were included in a prospective randomized study with the aim to assess the efficacy and tolerance of high-dose epirubicin (120 mg/m2) in combination with either cyclophosphamide (800 mg/m2; arm 1) or cisplatin (60 mg/m2; arm 2). Ninety-six patients were evaluable for response and toxicity and additional 12 patients for toxicity only. The overall response rate (CR+PR) in arm 1 and 2 were 61.4 (27/44) and 67.3% (35/52), respectively. The mean duration of remission was 4.4 months (arm 1) and 4.9 months (arm 2). The mean survival time was 6.6 months in arm 1 and 7.7 months in arm 2. WHO grade 4 toxicity was encountered in 25.5 and 15.8% of patients in arm 1 and 2, respectively. One case of cardiotoxicity resulting in the patient's death was observed in arm 1. Both combinations showed considerable antitumor activity. Toxicity was acceptable.

Abstract
One hundred forty-one patients with advanced breast cancer who had not received prior chemotherapy were randomly assigned to receive doxorubicin 60 mg/m2 or epirubicin 90 mg/m2 every 3 weeks. These doses were selected to produce equivalent toxicities. All patients were assessed for toxicity, and 138 patients were assessable for response. After a median of five treatment cycles, 47% (32 of 68) of doxorubicin-treated patients achieved a partial or complete response. Response duration and survival were 10 and 12 months for doxorubicin and 8 and 10 months for epirubicin, respectively. Noncardiac toxicities were similar for both drugs. Of 41 patients receiving doxorubicin who had serial left ventricular ejection fraction assessments, seven sustained a fall of 10% or more, and one patient developed congestive cardiac failure at a cumulative doxorubicin dose of 489 mg/m2. Of 39 patients receiving epirubicin who had serial cardiac assessments, five sustained left ventricular ejection fraction falls of 10% or more and two patients developed congestive cardiac failure at cumulative doses of 178 mg/m2 and 833 mg/m2. These data indicate that an epirubicin dose of 90 mg/m2 produces toxicity equivalent to doxorubicin 60 mg/m2 but does not improve response rates, response duration, or survival in advanced breast cancer.

Abstract
Epirubicin, a new anthracycline, was used in combination with cytosine arabinoside for the induction therapy of de novo acute nonlymphocytic leukemia in childhood. The treatment consisted of epirubicin 20 mg/m2/day for 3 days and cytosine arabinoside 100 mg/m2/day for 7 days. The treatment could be repeated every 3 weeks. Remission induction rate was 80% (20/25). Moreover, in 13 patients, the remissions were obtained after a single course. In general, the side effects of epirubicin and cytosine arabinoside were tolerable. However, the main causes of all the three deaths were infections. Our study suggests that epirubicin is acceptable and effective for the induction therapy for de novo acute nonlymphocytic leukemia in childhood.

Abstract
In a pilot study of the combination of epirubicin and chlorambucil in the treatment of chronic lymphocytic leukemia (CLL), 10 patients with advanced or progressive disease were treated in four centres. Up to a total of 15 courses in individual patients were given. Toxicity was relatively mild with nausea due to epirubicin being the most commonly reported side-effect. One patient developed a probable septicemia during a period of neutropenia. In another patient who died from probable Pneumocystis carinii pneumonia (PCP) after only one course of therapy, death could not be regarded as necessarily treatment-related. In seven previously untreated patients, one complete response and four partial remissions were seen. All three previously treated patients showed partial remissions.

Abstract
An overview of all published randomized trials which compared mitoxantrone or epirubicine to adriamycin was performed to analyse tolerance, toxicity and efficacy of these drugs, related to adriamycin. Mitoxantrone confirms its better tolerance: nausea and vomiting are less frequent (P < 10(-9)) and alopecia less intensive (P < 10(-9)). There is a significant decrease in cardiotoxicity occurrence with mitoxantrone (P < 0.01) but a significantly higher degree of leucopenia (P < 10(-4)). As far a response rate is concerned, mitoxantrone is somewhat less effective than adriamycin (P < 0.001). As compared to adriamycin, epirubicine does not reduce side effects incidence, nevertheless, their intensity is less important: nausea and vomiting (P < 0.04) and alopecia (P < 0.01). Leucopenia is less frequent following epirubicine administration as compared to adriamycin, documented course by course (P < 0.01) or on the overall treatment (P < 0.01). Epirubicine is noted to be less cardiotoxic than adriamycin (P = 0.001) with a decreased incidence of heart failures (P < 0.05). No difference can be observed in response rate between these two treatments, for objective as well as for complete responses.

Abstract
24 patients with unresectable non-small cell lung cancer (NSCLC) (14 stage IIIB and 10 stage IV) with a performance status of 70% or higher and without liver metastases received 120-165 mg/m2 epirubicin as an intravenous bolus every 21-28 days up to the maximum cumulative dose of 900 mg/m2. 6 patients (25%) (95% confidence limits 9.8-46.7%) achieved partial remission for a median duration of 7.5 months (range: 3-13+). The median dose actually administered per course was 120 mg/m2 in responsive and non-responsive patients. The dose-limiting side-effect was neutropenia. 1 patient receiving the higher dose died of drug-related infection. Other non-dose-related grade 3 side-effects were alopecia (100%) and vomiting (17%). In 4 patients, the treatment was interrupted because of a greater than 10% reduction in the left ventricular ejection fraction as calculated by radionuclide angiocardiography. None of these patients suffered from cardiac symptoms. The median survival was 10 months (range 1-16). These data suggest that epirubicin at 120-135 mg/m2 may have higher antitumour activity than standard doses in patients with NSCLC. Further studies are needed to clarify whether or not high-dose epirubicin increases, the risk of cardiotoxicity compared to standard doses.

Abstract
Ondansetron was compared with metoclopramide for antiemetic efficacy in a randomised double-blind trial in 122 patients with advanced breast cancer. All patients were treated with epirubicin (greater than 50 mg/m2) and cyclophosphamide (greater than 500 mg/m2). 50 patients receiving ondansetron and 60 with metoclopramide were considered evaluable. Ondansetron was at least as effective as metoclopramide in the control of vomiting and nausea. The percentage of patients with complete plus major control was 72% (59-85%) vs. 61% (48-74%) on day 1 (P = 0.230) and 79% (67-91%) vs. 66% (53-78%) on days 2-3 after chemotherapy (P = 0.122). Over the 3-day study period, nausea was absent or mild in 60% of the patients treated with ondansetron, compared to 45% given metoclopramide (P = 0.064). No major drug-related side-effects were reported. 1 patient receiving ondansetron experienced gastrointestinal disturbance and headache. Episodes of diarrhoea, fever, hyperkinetic syndrome, fatigue, restlessness and migraine with vomiting were reported by 5 patients treated with metoclopramide. None of the changes in the biochemical or haematological parameters was attributed to the antiemetic treatments.

Abstract
A comparative randomized study of intra-arterial infusion chemotherapy (IA) and systemic chemotherapy (IV) was carried out on 41 patients with locally advanced breast cancer, and the following results were obtained. 1) The response rate of primary lesions to IA (63.2%) was better than that of IV (40.9%). 2) In the patients treated with IA, grade of leukopenia, as well as the percentage of gastro-intestinal disorders, was low. 3) More prolonged follow-up studies are required on the therapeutic effects on micrometastasis. The author confirmed that IA was an efficacious neoadjuvant therapy in terms of down staging of locally advanced breast cancer.

Abstract
We determined the ability of the multidrug resistance (MDR) reversal agent cyclosporin-A to increase anthracycline drug accumulation in colorectal tumour cells in vitro, using the technique of on-line flow cytometry. Data of four previously untreated patients showed that cyclosporin-A can increase intracellular net-uptake of daunorubicin. A phase II study was initiated in 24 colorectal cancer patients. They received cyclosporin-A at a dose of 3 mg kg-1 over 1 h as i.v. infusion, at 7 h and at 1 h preceding cytotoxic drug administration. At the end of the second cyclosporin-A administration epidoxorubicin 90 mg m-2 was administered as i.v. bolus. Cycles were repeated every 3 weeks. Median cyclosporin-A peak blood levels and levels at 18 h after cytotoxic drug administration appeared to be 6248 ng ml-1 and 1012 ng ml-1 respectively. Only one partial response was observed, despite these high cyclosporin-A levels. Cyclosporin-A did not cause major toxicity, only a 29% incidence of hot flushes was observed. Epidoxorubicin toxicities were as expected but the frequency of severe leucocytopenia was striking. This treatment schedule can not be considered active in colorectal cancer.

Abstract
We evaluated the efficacy of epirubicin in a phase II trial in breast cancer, as well as its cardiac toxicity. The study was carried out on 40 female patients with advanced, metastatic, or recurrent breast cancer. The patients were grouped into two groups: group I received 30 mg/m2 epirubicin weekly, and group II 90 mg/m2 epirubicin every 3 weeks. Cardiac monitoring was by ECG, roentgenography, echocardiography and endomyocardial biopsies. Clinical results were 35.3% overall response in group I, and 50% overall response in group II. No untoward cardiac toxicities were encountered. We conclude that epirubicin is an effective agent in breast cancer with relatively little cardiac toxicity.

Abstract
0.5 mg tetracosactrin is considered to be equivalent to 40 mg methylprednisolone with regard to the induced cortisol secretion. 97 female breast cancer patients who received their first two FEC courses (epirubicin 50-75 mg/m2, 5-fluorouracil 500 mg/m2, cyclophosphamide 500 mg/m2) entered this randomised crossover study (76 had previously received an adjuvant treatment); tetracosactrin was administered intramuscularly and methylprednisolone intravenously immediately before chemotherapy administration. The tolerability was evaluated using a diary card during 5 days and patients were asked for their preference at the end of the two cycles. There was no difference either for vomiting (dry heaves were included) or nausea between the two treatments (the analysis was performed on day 1, the worse day of days 2 and 3 and the worse day of days 4 and 5). At day 1, 49% of the patients experienced no or mild nausea after tetracosactrin and 62% after methylprednisolone (not significant) (first period analysis); a complete control of vomiting (including dry heaves) was observed in 49% of the patients after tetracosactrin and 53% after methylprednisolone (not significant). No difference was observed between patients with or without previous chemotherapy. However, slightly more patients preferred tetracosactrin (P = 0.048).

Abstract
27 patients with FIGO stage III-IV endometrial adenocarcinoma were entered in a phase II trial evaluating activity and safety of epirubicin given at 80 mg/m2 intravenously every 3 weeks. 2 complete remissions (including a pathological one) and 5 partial responses were observed for a response rate of 26% (95% confidence interval 11-46). The median time to progression and median survival for all treated patients was 6 and 9.5 months, respectively. Treatment was well tolerated. Haematological toxicity was mild. The median total cumulative dose of epirubicin was 480 mg/m2 (160-880) and cardiac toxicity was not observed. Further studies with higher doses of epirubicin in combination with other active drugs are indicated.

Abstract
Sixty-nine unselected patients with locally advanced and metastatic carcinoma of the pancreas, who had not received previous chemotherapy or radiotherapy were randomised to receive either 5-fluorouracil, epirubicin and mitomycin C (FEM) or epirubicin. Survival was not significantly different in the two arms. Toxic reactions (WHO grade greater than 3) in the FEM and epirubicin arm respectively included nausea (2), (4), severe alopecia (1) (3) and leucopenia (1), (5), none of these were statistically significant. We therefore suggest that combination chemotherapy should not be used in preference to single agent chemotherapy as standard treatment for locally advanced or metastatic cancer of the pancreas.

Abstract
45 patients with oral cancer preoperatively received regional intraarterial chemotherapy (RIAC). All patients developed stomatitis or glossitis limited to the region of cytostatic perfusion. Between 1 and 19 days (median 4 days) after RIAC the tumor was removed by hemiglossectomy, partial resection of the floor of the mouth etc. The tissue alterations induced by chemotherapy in these surgical specimens were analyzed histomorphologically. Stomatitis due to RIAC was characterized by necrosis, ulceration and severe epithelial dysplasia of mucous membranes. Approximately 2 weeks after chemotherapy both the inflammatory changes and the dysplasia had disappeared completely. The differences between spontaneous premalignant dysplasia of the oral cavity and dysplasia induced by RIAC are discussed.

Abstract
24 patients with non-Hodgkin lymphoma were randomized into two multidrug regimens including either epirubicin (N = 12) or doxorubicin (N = 12) to establish the cardiotoxicity of each treatment modality. At cumulative doses of 400-500 mg/m2 left ventricular ejection fraction (LVEF) at rest determined by radionuclide angiocardiography decreased significantly more in the doxorubicin (-15 +/- 11%) than in the epirubicin group (0 +/- 13%, p less than 0.005). During epirubicin therapy no clinically significant cardiotoxicity developed, but a decrease larger than 10% in LVEF was seen in 4 of 12 patients at a mean cumulative level of 450 mg/m2. During doxorubicin therapy 1 patient developed a heart failure at a cumulative level of 200 mg/m2 and, altogether, in 7 patients LVEF decreased more than 10%. The monitoring of cardiac toxicity is imperative in patients treated with doxorubicin and is advisable if the patient is expected to receive epirubicin at more than 450 mg/m2.

Abstract
Lonidamine revealed synergistic effects with anthracyclines and alkylating agents in experimental investigations. It differs from conventional cytostatics by acting on the cell energy metabolism and also lacks their typical side effects; therefore it may be valuable to be combined with established chemotherapeutic regimens. Because in unselected patients the results of randomized studies may be influenced by differences in type and combination of prognostic factors, we defined strict entry criteria: no previous systemic palliative treatment, disease-free interval less than or equal to 2 years, measurable visceral metastases, number of tumor sites less than or equal to 2, no brain or bone metastases, World Health Organization performance status less than or equal to 2, age less than or equal to 55. In an ongoing rate, remission duration, time to treatment failure, and survival time in patients treated with vindesin 3 mg/m2 plus epirubicin 100 mg/m2 plus cyclophosphamide 600 mg/m2 (day 1, intravenous, repeated every 3 weeks) +/- lonidamine 600 mg/day orally. Eight of 12 patients achieved an objective remission (complete response 4, partial response 4), 1 patients had a stable disease, 2 patients experienced tumor progression; 1 patient is not yet evaluable for response. In spite of the intensity of the therapy no treatment interval prolongation was necessary. Main toxicities were myelosuppression, nausea, emesis, alopecia, and in patients treated with lonidamine, mild myalgia. The addition of lonidamine to polychemotherapy did not affect myelosuppression. Differences in remission rates or remission duration due to lonidamine could not yet be demonstrated.

Abstract
Hepatic biloma (bile cyst) developed in a patient after transcatheter oily chemoembolization (TOCE) with Lipiodol for hepatocellular carcinoma. The patient was treated conservatively and underwent the next TOCE uneventfully. An inappropriately large dose of Lipiodol, anticancer agent, and Gelfoam can induce biloma; however, it is not reasonable to abstain from TOCE for hepatocellular carcinoma in fear of biloma.

Abstract
Twenty-eight patients with small cell lung cancer were treated with high dose 4'-epidoxorubicin (EDX). Fifteen patients underwent EDX monotherapy (cumulative dose: 800 mg/m2) while 13 were treated with EDX (cumulative dose: 660 mg/m2) associated with cyclophosphamide, etoposide and cisplatin. A 2D-echo was performed in basal condition, after the third and sixth dose and 2 months after the end of the therapy. In the patients without cardiovascular disease (n = 19) left ventricular end-diastolic volume (EDV), end systolic volume (ESV) and ejection fraction (EF) were unchanged. The patients with coronary artery disease (n = 5) showed a statistically significant decrease in EF with an increase of ESV. All patients with systemic hypertension (n = 4) showed a significant reduction of EF and a significant increase of ESV and EDV.

Abstract
Seventy-one patients with T2 and T3 bladder cancer were randomized to receive either two courses of epirubicin 120 mg/m2 i.v. push every 21 days pre-operatively, and four additional courses post-operatively (group I = 34 patients), or radical surgery (group II = 37 patients). At a median follow-up of 24 months (range 22 months to 38 months) 25 patients from group I and 14 patients from group II are still alive and disease-free. The estimated two-year disease-free survival percentages were 73.5 and 37.9%, respectively (P = 0.05). After initial chemotherapy, resected specimens were subjected to histopathological study of chemotherapeutic effects. Necrosis was detected in 95% of cases with squamous cell carcinoma and in 57.3% of cases with transitional cell carcinoma. We conclude that the benefit which was obtained by pre-operative and post-operative chemotherapy with epirubicin is promising and may represent a significant improvement in the treatment of patients with carcinoma of the bilharzial bladder.

Abstract
The French Epirubicin Study Group carried out a randomized trial comparing epirubicin alone 75 mg/m2 with fluorouracil (5FU) 500 mg/m2, cyclophosphamide 500 mg/m2, and epirubicin 50 mg/m2 (FEC 50) and 5FU 500 mg/m2, cyclophosphamide 500 mg/m2, and epirubicin 75 mg/m2 (FEC 75) as first treatment for advanced breast cancer patients. Patients were stratified according to whether or not there were bone metastases only. Four hundred twelve patients entered this trial; 378 were assessable for tolerability and 365 for efficacy. The overall response rates were comparable between FEC 50 (44.6%) and FEC 75 (44.7%), but both were better than the epirubicin alone (30.6%) (P = .04 and P = .0006, respectively). The complete response rate was better in FEC 75 (15.5%) than in FEC 50 (7%) (P = .025) or epirubicin (4%) (P = .002). Similar results were obtained in the group of patients without bone-only metastases. No difference in the three treatments was observed in the patients with bone metastases only. Mean durations of response were similar in the three groups, being 412 days, 440 days, and 350 days for FEC 50, FEC 75, and epirubicin, respectively. Patients without previous adjuvant chemotherapy fared better than those with previous treatment (without anthracyclines). Tolerability was fair in the three groups. Overall, the epirubicin-alone group showed better tolerance than the two other groups, which did not differ significantly. Time to progression and survival were not different among the three groups, but more early relapses occurred in the epirubicin and FEC 50 groups; survival seemed to be better during the first 8 months in the FEC 75 group, and the survival difference between the epirubicin group and the FEC 75 group was of borderline significance. No difference in survival was observed between epirubicin- and FEC 50-group patients, even though the response rate was significantly worse in the monochemotherapy group.

Abstract
Fifty-six patients with measurable advanced soft-tissue sarcomas were treated with epirubicin, 90 mg/m2 intravenously on day 1, and DTIC, 250 mg/m2 intravenously on days 1-5, with the entire regimen repeated every 3 weeks. The overall response rate in 52 evaluable patients was 48% with 9 complete remissions. Noncardiac toxicity was limited predominantly to vomiting, alopecia and myelosuppression. Laboratory evidence of cardiotoxicity [greater than or equal to 20% decrease in left-ventricular ejection fraction (LVEF) from the baseline value] was observed in 4 out of 39 patients who had at least two determinations of LVEF, at a median dose of 1,305 mg/m2. Two patients had clinical congestive heart failure at cumulative dose of 1,440 and 1,620 mg/m2. These findings suggest that the combination of epirubicin and DTIC is an active regimen in soft-tissue sarcomas, and provide further evidence that epirubicin is a doxorubicin analogue with reduced cardiac toxicity, but preserved efficacy in this disease.

Abstract
4'-Epidoxorubicin (Epi-A) administered immediately prior to liver resection has been suggested as treatment for patients with primary liver carcinoma. Long-term toxicity was studied in rats given a single dose of Epi-A intravenously immediately prior to a standard partial hepatectomy (PH). After 52 weeks only 9% of the rats given 5 mg/kg + PH were alive, 79% of the rats given 2 mg/kg + PH and 92% of the PH control survived. The weight gain of the rats given 5 mg/kg + PH was only 17% of that of PH controls. Signs of congestive heart failure were observed in some rats while in others moderate kidney lesions. No histopathological lesions were detected by light microscopy in heart, liver, spleen and bone marrow. For the rats given 2 mg/kg + PH body weight gain, microscopic observations and blood chemistry data (total protein, albumin, alkaline phosphatase, alanine aminotransferase, total bilirubin, creatinine and urea) were comparable to the PH controls. No significant differences in survival were registered between partially hepatectomized and sham-operated rats. The results indicate that Epi-A may be given preoperatively to liver resection without inducing long-term effects on vital organs.

Abstract
Thirty consecutive patients with FIGO stage III-IV, squamous cell uterine cervix cancer were entered in a phase II trial evaluating activity and safety of epirubicin when given at a dose of 80 mg/m2 i.v., every 3 weeks. Two complete responses (including a pathological complete remission) plus 3 partial responses were observed among 27 evaluable patients with a response rate of 18.5% (95% confidence limits = 7.6%-36.4%). The median time to progression and median survival for all treated patients were 3 and 8 months respectively. Treatment was well tolerated. Haematological toxicity was mild. WHO grade 4 toxicity was not observed. The median total cumulative dose of epirubicin was 360 mg/m2 (80-840 mg/m2). Congestive heart failure was not noted. Further studies in cervical cancer with higher doses of epirubicin as single agent or in combination with other nonmyelotoxic drugs are indicated.

Abstract
Detailed pharmacokinetic analysis and subsequent evaluation of myelotoxicity were performed in 55 patients who had been randomized to 4 different doses of epirubicin (40, 60, 90 or 135 mg/m2 given i.v. every 3 weeks). A significantly positive correlation was demonstrated between the AUC and the myelotoxicity of epirubicin. A similar correlation was observed when the metabolite epirubicinol was also considered. The decrease in leucocyte count as expressed by the logarithmic ratio between nadir WBC and initial WBC was linearly correlated with the AUC of either epirubicin alone (r = -0.55, P less than 0.001) or epirubicin and epirubicinol together (r = -0.63, P less than 0.001). As a relationship between the concentration of epirubicin in a single plasma sample taken at 6 h following i.v. administration and the AUC of the drug has been established, a log-linear relationship between the expected decrease in leucocytes and the concentration at 6 h after administration could be calculated. The proposed model is expressed as the equation: log WBCnadir = log WBCinitial -0.0073 x c6 (ng/ml)-0.14.

Abstract
Seventy-five patients with recurrent bladder carcinoma were randomized after electroresection to receive either epirubicin (E) or epirubicin + verapamil (E + V) instillation of the bladder at regular intervals for 2 years. Samples of the bladder wall, tumour tissue and peripheral blood were taken from 20 patients. The average follow-up period was 21 months. Fifty per cent of the patients in the E group and 37% in the E + V group developed recurrent tumours. Recurrence rates (RR) were 6.3 and 4.7, respectively. Before the instillation therapy the RR was 16.0. There was a highly significant reduction of RR during the instillation therapies; in group E p less than 0.005 and in group E + V p less than 0.001. The difference between the treatment groups was not statistically significant. Verapamil increased epirubicin concentrations in both the bladder wall and the tumour tissue, but did not affect concentrations in the peripheral blood. Side effects were few and did not lead to discontinuation of treatment.

Abstract
In an attempt to address the schedule of adjuvant chemotherapy in surgically resected T1 or T2NOMO small cell lung cancer, 12 patients were randomized to receive 6 courses of either single-agent (high-dose epirubicin) or combination (cyclophosphamide, epirubicin, and etoposide) chemotherapy, at 3-week intervals. No thoracic radiotherapy was administered while prophylactic cranial irradiation (30 Gy/10 fractions/2 weeks) was given. With a 25-month median followup, overall estimated 2-year and median survival were 83% and 26.5 months (range 16-34+), respectively. Ten patients are currently alive and disease free. No significant difference in 2-year survival was observed between the two adjuvant treatment modalities and median survival was 28 months (range 13-34+) for combination and 21 months (range 14-29+) for single-agent chemotherapy. Although at high doses, epirubicin resulted in a moderate clinical and histological cardiotoxicity and a remarkably reduced incidence of severe (WHO grades 3 and 4) treatment-related morbidity compared with the combination regimen. These preliminary results suggest that comparable survival and reduced toxicity might be expected with an active single-agent as adjuvant chemotherapy in T1 or T2NOMO small cell lung cancer.

Abstract
Epirubicin (4'-epidoxorubicin), an analogue of doxorubicin (Adriamycin), has established activity in the treatment of small-cell lung cancer (SCLC) when used at doses of 75 to 120 mg/m2 in previously untreated patients. We completed a phase II study of epirubicin (85 mg/m2 given intravenously at 3-week intervals) in 20 patients with recurrent SCLC, all of whom had received prior combination chemotherapy. Of 19 patients who were assessable for response, 2 achieved a complete response and 2 a partial response, for an overall response rate of 4/19 (21%); 95% confidence interval, 8%-43%). Myelosuppression and alopecia were the most frequent toxicities; epirubicin was otherwise well tolerated, with other toxicities such as nausea and vomiting being infrequent or mild. Epirubicin at a dose of 85 mg/m2 exhibits modest single-agent activity in previously treated SCLC and is generally well tolerated. Given as a single agent or in combination with other well-tolerated drugs, epirubicin would be suitable in cases in which palliation of symptoms without undue toxicity is required in the management of previously treated SCLC.

Abstract
Fifty evaluable patients with advanced lung cancer (28 small cell and 22 non-small cell carcinomas), mainly pretreated by chemotherapy, received 4'-epi-doxorubicin 90 mg/m2 every 3 weeks. Two partial responses were obtained in small cell lung cancer patients, which lasted 153 and 168 days. Leukopenia, emesis and alopecia were the most frequent side effects. Two patients who previously received anthracyclines died suddenly of cardiac failure, another patient had severe congestive heart failure, and four others had minor cardiac dysfunctions. 4'-epi-doxorubicin has a modest activity in advanced lung cancer, mainly pretreated by chemotherapy and is not devoid of significant cardiotoxicity in this patient population.

Abstract
The cardiotoxicity of epirubicin (EPI) was evaluated clinically, radiologically, with ECG, and with multiple ECG-gated radionuclide determination of the left ventricular ejection fraction (LVEF) during rest in 135 patients with advanced breast cancer. The EPI doses were 60 mg/m2 on days 1 and 8 every 4 weeks or 45 mg/m2 plus vindesine 3 mg/m2 on the same schedule. The median cumulative dose of EPI was 500 mg/m2 (range, 47 to 1,563). Eight of the 135 patients developed congestive heart failure (CHF). Of 67 patients treated with EPI less than 500 mg/m2, none developed CHF. Among 48 patients treated with doses between 500 and 1,000 mg/m2, one had CHF (2%; 95% confidence limits, 0.1 to 11.1). Among 20 patients who received EPI from 1,000 to 1,563 mg/m2, seven developed CHF (35%; 95% confidence limits, 15.4 to 59.2). Four patients died due to cardiotoxicity. The risk of EPI cardiotoxicity at the present schedule is considerable at doses above 1,000 mg/m2. At doses between 500 and 1,000 mg/m2 the risk of CHF decreases, and at doses below 500 mg/m2, it is negligible. For all patients, the prevalence of CHF was 6% and the sensitivity of LVEF high (95%), mainly due to the low incidence of CHF. Among the 20 patients who received EPI at more than 1,000 mg/m2, the prevalence of CHF was 35% and the sensitivity only 64%. The specificity was maximally 62%. Our results suggest that LVEF is of no value as a predictor for CHF.

Abstract
We undertook this phase II study to evaluate the efficacy and toxicity of epidoxorubicin and ifosfamide in the treatment of locally advanced and/or metastatic soft-tissue sarcomas. We used escalating doses of epidoxorubicin (from 60 to 75 mg/m2) on day 1 and 1.2 g/m2 ifosfamide on days 1-5. Chemotherapy courses were repeated every 3-4 weeks. A total of 16 patients--13 who had not previously been treated and 3 who had undergone prior therapy with anthracyclines--entered the study. In all, 15 patients were evaluable for response and 16, for toxicity. At least two courses of chemotherapy were given. A complete remission (CR) was seen in 1 patient, a partial remission (PR) in 5, and a minor response (MR) in 1, for an objective response rate (CR + PR) of 40% (6/15); this value reached 50% in non-pretreated patients (6/12). Stable disease (SD) was observed in 40% (6/15) of patients. The relative dose intensity of epidoxorubicin ranged from 10 to 23.3 mg/m2 (median, 16.6 mg/m2). The time to objective response ranged from 4 to 12 weeks (median, 8.5 weeks). The duration of response was 4 months for the single CR, and that for the five PRs was 6+ months (range, 4-18 months). Toxicity was evaluated according to WHO criteria in 16 patients; it was mild and consisted mainly of alopecia, nausea and vomiting, and leucopenia. In only three patients did we observe grade 3 leucopenia. In one case an ifosfamide-associated encephalopathy occurred, but it regressed after 24 h. Neither chronic nor acute cardiac toxicity was reported. In this preliminary analysis, the response rate obtained with the combination of epidoxorubicin and ifosfamide was encouraging and the toxicity was acceptable.

Abstract
Epirubicin, a stereoisomer of doxorubicin, is reported to have equal antitumor activity with lower cardiac and systemic toxicity. Recently the maximum tolerated dose of this drug has been revised upwards with reported increased response rates. However, the pharmacokinetics of epirubicin at high doses have never been reported. Accordingly, this study was designed to evaluate the pharmacokinetics of epirubicin when administered as either a 15-min i.v. bolus or a 6-h i.v. infusion in a phase I study at high doses. Nineteen patients with a variety of malignancies were given a total of 52 cycles of epirubicin at doses of 90 to 150 mg/m2 given once every 3 weeks. The maximum tolerated dose was 150 mg/m2 epirubicin given either as a bolus or as an infusion. The major dose-limiting toxicity was neutropenia. Interpatient variation occurred in the pharmacokinetics at each dose level but overall there were dose-dependent pharmacokinetics. This was manifested as a disproportionate increase in plasma levels and areas under the curve as the epirubicin dose was increased from 90 to 150 mg/m2. The pharmacokinetics of epirubicin could best be described by an open two-compartment model. Peak plasma concentrations were attained at a median of 12 min following the bolus injection and concentrations approached the steady state within a median of 55 min following the start of the 6-h infusion. Administration of the 150 mg/m2 dose over the 6 h compared to the bolus administration was associated with a 92% decrease in peak concentration from 3088 +/- 1503 to 234 +/- 126 ng/ml. This was not associated with an appreciable change in hematological or nonhematological toxicities. The median distribution half-life was 10 min and the median elimination half-life was 42.0 h. The cumulative renal excretion of the parent compound accounted for less than 2% of the administered dose. The major metabolites in both plasma and urine samples were 4'-O-beta-D-glucuronyl-4'-epidoxorubicin, 13-S-dihydro-4'-epidoxorubicin, and 4'-O-beta-D-glucuronyl-13-S-dihydro-4'-epidoxorubicin. This study demonstrates that a 135 mg/m2 bolus infusion given on a 3-weekly schedule is an appropriate initial dose for further clinical studies.

Abstract
One hundred thirty-three evaluable patients with advanced breast cancer entered a randomized trial comparing epirubicin 60 mg/m2 with a combination of epirubicin 45 mg/m2 and vindesine 3 mg/m2 day 1 and 8 every 4 weeks. In all 10 premenopausal women an oophorectomy was performed. Seventy-five patients had previously received cyclophosphamide, methotrexate, and 5-fluorouracil (CMF) for advanced disease and 68 had received adjuvant chemotherapy (cyclophosphamide or CMF). Among evaluable patients (72 in the epirubicin group and 61 in the epirubicin + vindesine group) response rates were as follows: complete response--seven versus six; partial response--31 versus 22; no change--16 versus 17 (p greater than 0.40). Median time to disease progression was 6 months in both groups and median survival times were identical (12 months). Thrombocytopenia was less frequent in the epirubicin + vindesine group (p less than 0.01). In the epirubicin + vindesine group, mild to moderate peripheral neuropathy was observed in 40% of the patients. Congestive heart failure developed in one patient with a cumulative dose of epirubicin less than 1000 mg/m2 and in 7 of 15 patients who had greater than 1000 mg/m2. Four died of this cause. In conclusion, epirubicin is effective as a single agent for advanced breast cancer. The combination with vindesine does not increase its efficacy.

Abstract
Thirty-one patients were entered into a pilot study combining oral quinidine with epirubicin 100 mg m-2 as first line chemotherapy in advanced breast cancer. Three patients were treated with quinidine 1 g b.d., and developed symptoms of toxicity. Of eight subsequent patients treated with quinidine 500 mg b.d., two experienced tiredness and nausea and one severe oral toxicity with epirubicin. The remaining 20 patients received quinidine 250 mg b.d.; one developed cinchonism and one malaise, the remainder showing no excess toxicity compared with epirubicin alone. The median nadir WBC was similar with or without quinidine (2.3 vs 1.6 x 10(9) l-1) as was median nadir platelet count (175 vs 157 x 10(9) l-1). There was no evidence of significant cardiac toxicity. The median plasma quinidine level achieved was 5.6 mumol l-1 (range 2.1-22.1), which is within the range of concentrations which is effective in vitro at reversing experimental anthracycline resistance. A randomised controlled study is proposed to assess the impact of this potential modulation on the efficacy of epirubicin in advanced breast cancer.

Abstract
Seventy-five breast cancer patients scheduled to receive a first course (in a new cycle) of cyclophosphamide, fluorouracil, and doxorubicin (FAC) or epirubicin (FEC) participated in a double-blind crossover study to compare the antiemetic efficacy and safety of ondansetron (GR38032), a 5-hydroxytryptamine3 (5-HT3) receptor antagonist, and metoclopramide. Ondansetron was given as an 8 mg loading dose (4 mg intravenously [IV] plus 4 mg orally) before chemotherapy followed by 8 mg every 8 hours orally for 3 to 5 days. Metoclopramide was given as an 80 mg loading dose (60 mg IV plus 20 mg orally) before chemotherapy followed by 20 mg every 8 hours orally for 3 to 5 days. A "period" interaction in the analysis of emetic response in the first 24 hours necessitated a parallel group analysis of first treatments only, 68 patients being assessable for this parameter. In the first 24 hours, complete or major control (zero to two emetic episodes) of emesis was achieved in 30 of 35 (86%) patients receiving ondansetron and in 14 of 33 (42%) patients receiving metoclopramide (P less than .001). Ondansetron was also more effective in reducing acute nausea. On days 2 to 3, the complete or major responses were significantly better with ondansetron (81% v 65%; P = .033), but there was no statistical difference in the control of nausea. There was a significant patient preference for ondansetron (63% v 26%; P = .001). Extrapyramidal reactions were observed in two metoclopramide treatments; both treatments were otherwise well tolerated. These results are consistent with serotonin (5-HT), being a significant neurotransmitter of cyclophosphamide/doxorubicin- or epirubicin/fluorouracil-induced emesis.

Abstract
One of the local complications of certain chemotherapeutic agents is tissue necrosis resulting from extravasation. The purpose of this study was to evaluate the effectiveness of a conservative approach to treatment in order to minimize necrosis and the need for reconstructive surgery. Fifty-three patients entered this study. Twenty-one had old lesions while 32 had recent extravasations. Drugs responsible for the extravasations were doxorubicin, epirubicin, vinblastine, mitoxantrone, and mitomycin C. The basis of treatment was betamethasone ointment, which was applied to the lesion with a tight elastic bandage and was replaced every 12 hours for the first 2 days and then every 24 hours until complete healing. For old lesions a keratolytic ointment was initially applied, whereas in the new lesions multiple subcutaneous injections with hydrocortisone solution preceded the application of betamethasone ointment. None of our patients developed tissue necrosis and sloughing that necessitated surgery. All lesions healed in patients. Healing time varied with the different drugs used and was proportional to the extension of extravasation and to the time when therapy was begun. We conclude that the application of conservative measures in extravasated areas from chemotherapy may avoid tissue necrosis and reconstructive surgery.

Abstract
Forty-seven patients with advanced small-cell bronchogenic carcinoma (SCLC) were treated with a combination of epirubicin (4-EPIDX) (60 mg/m2 i.v.) and cisplatin (CDDP) (50 mg/m2 i.v.) on day 1, alternated with cyclophosphamide (CTX) (800 mg/m2 i.v.) day 1 and etoposide (VP16) (120 mg/m2 i.v.) on days 21-23. Four patients (9%) obtained a complete remission and 27 (57%) a partial remission with an overall remission rate of 66%. The median duration of response was 37 weeks (range 13-150) and the median duration of survival was 43 weeks (range 10-150). No severe bone marrow depression was noted. The other side-effects were of a mild grade.

Abstract
A single agent chemotherapy regimen, comprising epirubicin 120 mg m-2 iv at 21-day intervals for a maximum of six cycles was administered to 26 patients with intermediate or poor prognosis small cell lung cancer. Staging consisted of both conventional disease extent and prognostic guidelines based on laboratory parameters. The overall response rate was 57% which predominantly occurred among the intermediate prognosis group (14 of 17 patients), compared with only 1 of 9 patients in the poor prognosis category. Seven patients survived for at least 12 months, including one 3-year survivor (remains disease free). Chemotherapy toxicity was easily managed and chemoresponse was generally accompanied by an improvement in perceived performance rating. The study confirms the activity of epirubicin against small cell lung cancer and emphasizes the importance of patient selection within the spectrum of small cell lung cancer.

Abstract
Extravasation of doxorubicin and its derivative epirubicin, cause severe progressive tissue necrosis that requires early excision of all affected tissues. Doxorubicin and epirubicin are autofluorescent and this characteristic can be used to demonstrate and delineate extravasation by the aid of fluorescence microscopic study. In a rat model doxorubicin was injected intradermally in declining concentrations and the minimal detectable concentration was found to be 0.02 mg/ml. Skin necrosis developed in rats injected with doxorubicin concentrations ranging from 0.02 mg/ml to 2 mg/ml. Clinically, fluorescence microscopic analysis of frozen sections was used in eight patients to assess whether doxorubicin or epirubicin extravasation had taken place. When all fluorescing tissue was removed, no necrosis ensued, but in one patient, where a slightly fluorescing area was ignored, necrosis developed later and excision of the tissue had to be performed.

Abstract
The Clinical Trials Group of the National Cancer Institute of Canada (NCIC) studied single-agent epirubicin in 40 previously untreated patients with extensive small-cell lung cancer (SCLC). The starting dose of epirubicin was 100 (eight patients) or 120 (32 patients) mg/m2 administered intravenously every 3 weeks. Twenty patients (50%) achieved an objective response (95% confidence limits, 33% to 66%) and three of the 20 had complete responses (CRs). The median survival of all 40 patients was 8.3 months (35.4 weeks). Myelosuppression, mild or moderate nausea and vomiting, and hair loss were commonly seen. There was one chemotherapy-related death. This drug is active and well tolerated in SCLC and the use of it as first-line therapy did not appear to compromise survival in this group of patients.

Abstract
From June 1986 to December 1988, 107 patients (median age, 49 years; median performance score, 1) with haematogeneous metastases from breast carcinoma were treated with concomitant radiation and chemotherapy. Overall, 97% of the patients had been pretreated with surgery; 65%, with radiation; and 56%, with hormones. In all, 38% had received adjuvant chemotherapy. Patients with prior palliative chemotherapy were excluded from the study. All patients fulfilled at least two high-risk criteria. Chemotherapy was given according to the EI protocol (4-epirubicin and ifosfamide), and all patients simultaneously received radiation to the main tumour sites. Gastro-intestinal toxicity was moderate (11.1%, WHO grade 4), and bone marrow depression was marked in all cases. After three treatment courses, the overall response rate was 67% [21% complete response (CR), 46% partial response (PR)]. In all, 28% had stable disease (NC) and the rate of progressive disease (PD) was 5%. The median duration of tumour response was 8 months, with 12 months for CRs, 9 months for PRs and 6 months for NCs. The median survival was 13.5 months.
