Phase II studies of p.o. Idarubicin administration, a new daunorubicin analogue (4-demethoxy-daunorubicin), have shown antitumor activity in 23%-31% of previously treated metastatic breast cancer patients, while in untreated patients a response rate of 41% was observed. Our Phase II study has shown an overall response of 23% [1 complete response (CR), 9 partial response (PR), 10/43] with a daily dose of 15 mg/m2 p.o. on days 1,2,3. On the basis of these results we have recently included Idarubicin in combination chemotherapy of breast cancer, substituting Adriamycin by Idarubicin in an FAC schedule. Of 50 consecutive metastatic breast cancer patients who entered the study, 42 patients who received greater than 2 cycles were evaluable. There were 22 premenopausal and 20 postmenopausal patients (mean = 51 years). In 25 patients a performance status of 0-2 (ECOG) was registered and in 17 patients it was 3. Previous radiation had been administered in 34, hormonal therapy in 18, and adjuvant chemotherapy (CMF 5, CMFVP 3) in 8 patients; 22 patients had predominant metastatic sites in soft tissues, 18 in visceral organs, and 2 in the bones. The FIC schedule was administered as follows: 5-fluorouracil 500 mg/m2 i.v. days 1 and 8, Idarubicin 15 mg/m2 p.o. days 1, 2 and 3, and cyclophosphamide 500 mg/m2 i.v. day 1. An objective response was observed in 23 (5 CR, 18 PR) out of 42 patients (53%, CR 12%). Soft tissue metastases responded in 55% (12/22), visceral organs in 61% (11/18), and no response was observed in bone lesions (0/2). The median remission duration was 8 months (3-16+). Toxicity was mild, expressed mainly in the form of nausea/vomiting, grade I and II in 64% of the patients. Alopecia was very mild (grade I and II in 23% of the patients). Leukopenia grade I-II was observed in 21% of the patients. In 4 patients reversible ECG changes occurred. Left ventricular ejection fraction did not show any pathological changes. The Idarubicin-containing combination chemotherapy we have used has the following characteristics: easier administration (p.o. anthracycline, no risk of tissue extravasation), lower toxicity (cardiotoxicity, alopecia, and myelosuppression in particular), and a notable antitumor activity.

In order to find an effective and suitable chemotherapy regimen for preoperative treatment of esophageal cancer, patients with inoperable or metastatic disease were treated with a combination of etoposide and cisplatin. Of 27 evaluable patients, 13 had squamous cell carcinoma, 13 adenocarcinoma, and 1 muco-epidermoid carcinoma. No complete responses were noted. Nine of 13 patients with squamous cell carcinoma and only one of 13 with adenocarcinoma showed a partial response. Nine of 10 responders achieved a partial response after 2 courses, one after 4 courses. There was one toxic death, due to sepsis during leukopenia. Other toxicities were alopecia, nausea and vomiting, nephrotoxicity, thrombocytopenia and leukopenia.

The effects of levamisole on the course of Leishmania enriettii infection in guinea-pigs and L. major in mice were investigated. It was demonstrated that levamisole-treated guinea-pigs either did not develop an ulcerative lesion or developed a much smaller lesion than untreated animals. Moreover, metastases which are commonly produced in approximately 50% of animals receiving 2 x 10(6) L. enriettii did not occur in levamisole-treated guinea-pigs. Leishmania enriettii infection usually causes leukopenia and eosinophilia in guinea-pigs approximately two to three weeks after infection. These haematological changes did not occur in animals receiving levamisole. The percentage of rosette T-cells which diminished in the L. enriettii infection was normalized in the group of levamisole-treated and infected guinea-pigs. The severity of Leishmania infection in mice receiving levamisole was lower in comparison to a control group of the animals.

Experimental data show that sequencing methotrexate (MTX) and 5-fluorouracil (5-FU) may result in synergistic antitumor activity. Moreover, the effect of 5-FU is increased by folinic acid (FA), and finally, cyclophosphamide (CPA) produces an expansion of tumor growth fraction, suggesting an increased cytotoxic effect of cycle-specific drugs subsequently administered. Based on these premises, we have performed a Phase II study with CPA (600 mg/m2 i.v., day 1), MTX (200 mg/m2 1-h i.v. infusion, day 7), 5-FU (600 mg/m2 i.v., day 8), and FA (500 mg/m2 2-h i.v. infusion, day 8 plus 15 mg p.o. every 6 h on days 8 and 9) administered every 3 weeks. Thirty-six patients with metastatic breast cancer were admitted into the study. Median age was 52 years, and all but two patients were postmenopausal. Dominant sites of metastases were soft tissues in 10 patients, bones in 7 patients, and viscera in 19 patients. All patients were pretreated with chemo- and/or hormone therapy. Sixteen patients achieved an objective response (44.5%: 1 complete response and 15 partial responses), 8 had stable disease (SD) (22.2%), and 12 progressed (33.3%). Twenty-one patients had previously received conventional CMF in an adjuvant setting (15 patients) or for metastases (6 patients): 1 complete response (CR) and 7 partial responses (PR) were obtained in the first group and 1 in the second. Major toxic effects were hair loss (56.4%), nausea and vomiting (72%), mucositis (52.5%), and leukopenia (61%). A randomized study could be useful to assess the role of sequential CMF versus conventional CMF in metastatic breast cancer patients.

A non-randomized clinical study on systemic combination chemotherapy was conducted by the Japanese Urological Cancer Research Group for Adriamycin to compare the effectiveness of CAP (cyclophosphamide 200-500 mg/m2, adriamycin 30-50 mg/m2 and cisplatin 30-50 mg/m2) and CAF (cyclophosphamide 200-500 mg/m2, adriamycin 30-50 mg/m2 and 5-fluorouracil 250 mg/m2) in 123 patients (104 evaluable) with advanced and/or metastatic cancer of the urinary bladder. Among 96 patients who were non-randomly selected to receive CAP, 4 achieved complete remission, 12 achieved partial remission, 7 achieved minor response, 30 had stable disease, and 43 had disease progression. The response in the 8 patients who received CAF were: partial remission in 1 and progressive disease in 7. The overall response rate to CAP therapy was 17%, as against 13% for CAF therapy. The median duration of survival with CAP was 29 weeks and with CAF, 22 weeks. The differences between the two groups in duration of survival and response rate were not statistically significant. Complete and/or partial remissions were observed in the lymph nodes, lung and liver in 32%, 24%, and 57% of cases, respectively. There was no objective response in bone metastasis. The main side effects of CAP were anorexia (88%), nausea and/or vomiting (81%), alopecia (65%), leukopenia (72%), anemia (48%), and renal dysfunction (17%). No patients died as a result of toxicity of these combination chemotherapy modalities.

Forty-five patients with advanced non-small cell lung cancer (NSCLC), with progressive inoperable tumors were treated. Twenty-three patients were of "limited" stage. Six patients had received previous thoracic radiotherapy. Patients with central nervous system (CNS) metastases, Karnofsky scores of less than 30 or more than 70, and patients over 70 years of age were excluded from the study. Cyclophosphamide (2.5 g/m2) was infused intravenously over 3 hours with the same Mesna dose. At the midpoint of the infusion, 3.5 g/m2 infosfamide was delivered as a bolus. Additional Mesna was administered over the next 8 hours. A maximum of four courses were given at three weekly intervals. One-hundred-thirty-eight courses were administered and 53% of patients completed all four treatments. The response rate was 38%, with three (7%) complete responses. Seven additional patients (15%) with stable disease symptomatically improved by two steps or more on the Karnofsky scale at the end of treatment. Median survival for all 45 patients was 7 months, range less than 1 to 25 months. Sixteen courses were complicated by Grade 3 thrombocytopaenia and/or leukopenia (Grade 4 on six occasions, Grade 3 on seven occasions) on the blood count taken immediately before chemotherapy. Intravenous antibiotics were required on 14% of the total number of courses; and three patients died of probable treatment related causes. Two episodes of severe ifosfamide encephalopathy occurred but recovery was complete, and four episodes of frank hematuria also occurred. The Karnofsky score was more than 70 in 33% of patients one month after the end of chemotherapy compared with 0% before treatment. Unlike many chemotherapeutic regimens for NSCLC, double alkylating agent treatment with ifosfamide and cyclophosphamide improved the performance status without major toxicity in a selected patient population. The overall survival, however, remains short and further alkylating agent combinations need to be considered in the future.

Transcatheter arterial chemoembolization (TAE) and hepatic arterial infusion using totally implantable reservoir were performed for the treatment of liver metastasis of colo-rectal cancers, and their therapeutic effects, side effects and complications were evaluated. Eleven cases of H1 (metastasis in one lobe only), 7 cases of H2 (a few scattered metastases in both lobes), 12 cases of H3 (numerous metastases in both lobes) were entered into the study and underwent TAE 45 times. Gel foam, Ivaron and Lipiodol were used as embolic materials in combination with chemotherapeutic agents such as mitomycin C and adriamycin. Serum CEA level was decreased less than 50% of pre-TAE level 20 out of 32 (61%). The tumor size was regressed in 25% of TAE cases which were evaluated on the basis of CT scan. Abdominal symptoms including abdominal pain, nausea and vomiting and fever, leukocytosis, elevated GOT, LDH and bilirubin level were seen after TAE therapy. Median survival of H1, H2 and H3 cases were 21 months, 8 months and 4.5 months, respectively. Another 21 cases (H1, 5 cases: H2, 3 cases: H3, 13 cases) of liver metastasis of colo-rectal cancers were treated with selective hepatic arterial infusion therapy using totally implantable reservoir. Reservoir catheters were implanted into hepatic artery via gastroduodenal artery under direct vision at laparotomy. Mitomycin C, adriamycin and fluorouracil (5-FU) were used as chemotherapeutic agents. No particular side effect such as leukopenia or liver dysfunction was noted. Median survival of H1, H2 and H3 cases treated with arterial infusion were 4 months, 9 months and 9 months, respectively. Median survival of TAE cases and arterial infusion cases was 10 and 6 months, respectively. Thus, the survival rate of cases treated with TAE was better than that of cases treated with arterial infusion.

10-Ethyl-10-deazaaminopterin (10-EDAM) is an analogue of methotrexate with improved preclinical anticancer activity, more selective entry, and greater conversion to polyglutamate forms in neoplastic cells. In this Phase I trial, we have treated 62 adults with advanced solid tumors, giving 10-EDAM i.v. on either a weekly x 3 schedule (35 patients) or a weekly schedule (27 patients). The dosage levels ranged from 5 to 120 mg/m2. The toxicity observed with 10-EDAM was qualitatively similar to that of methotrexate. Oral mucositis was the dose-limiting toxicity; diarrhea, skin rash, leukopenia, thrombocytopenia, and mild elevations of serum glutamic-oxaloacetic transaminase, prothrombin, and partial thromboplastin times were also observed, but were not dose limiting. A weekly dosage of 80 mg/m2 with escalation or attenuation in accordance with patient tolerance, or 100 mg/m2 weekly for 3 weeks, followed by a 2-week "rest period" are recommended for Phase II assessment. 10-EDAM produced partial remissions in three patients with non-small cell lung cancer and one patient with breast cancer lasting 6, 40+, 26+, and 15 months, respectively. Pharmacokinetic studies carried out at the 5, 30, and 100 mg/m2 dosage levels demonstrated the drug to have a triphasic disappearance from plasma. Elimination was independent of dose over the range tested, with mean plasma half-lives of: alpha = 12.9 min, beta = 1.5 h, and gamma = 11.9 h. Cumulative urinary excretion of the drug ranged from 13 to 55% of the administered dose (mean = 33%); 88% of the urinary drug appeared within the first 4 h following drug administration. The pharmacokinetic behavior of the first and second weekly dosages were consistent within a given patient. The metabolites 7-hydroxy-10-EDAM, and 10-ethyl-10-deaza-2,4-diamino-pteroic acid were demonstrated in the plasma and urine of treated patients. In studies of tissue homogenates from two patients with skin metastases, more extensive retention of the drug and of its polyglutamates was observed in the breast cancer metastases than in the metastases from a kidney cancer or in normal skin.

Ifosfamide (IFOS) 5 g/m2 and its parent analog Cyclophosphamide (CYCLO) 1.5 g/m2 were studied in a randomized phase II study, accruing 171 patients with advanced soft tissue sarcoma. Both drugs were administered as 24 hr infusions, every 3 weeks, with comcomitant Mesna 400 mg/m2 i.v. bolus 4 hourly X 9 doses. Twenty-four patients were ineligible and 12 were not evaluable. The groups were well matched for age, previous chemotherapy (42% of the total) or radiotherapy, the presence of distant metastases and performance status, but there were more females (59% vs. 45%) in the IFOS arm. Among the 68 evaluable patients receiving IFOS, there were 2 CR, 10 PR (overall response 18%), 27 SD and 29 PD. For CYCLO, the corresponding results in 67 patients were 1 CR, 4 PR (overall response 8%), 23 SD and 39 PD. Using the chi-square test the P values for response rate and linear trend were 0.13 and 0.04 respectively. Response rates were higher for females (20% vs. 5%, P = 0.01) and patients who had not received previous chemotherapy (19% vs. 4%, P = 0.01). Fourteen of the 17 responses came from a group of 43 females, who had not received previous chemotherapy, for whom the overall response rate was 37.5%. Remissions were noted in only 4 histological subtypes (centrally reviewed material), i.e., 5 of 17 synovial sarcomas, 7 of 13 mixed mesodermal sarcomas and 2 of 7 fibrosarcomas. One of the 31 leiomyosarcomas responded to Cyclophosphamide. Durations of response did not differ significantly between the 2 arms--median 26, range 10-81+ weeks. Leucopenia was significantly more severe on CYCLO, particularly in patients who had received previous chemotherapy (P = 0.007). Serious infections occurred in approx. 7% of patients with no difference between the two drugs, although there was one toxic death on CYCLO. Nausea and vomiting were significantly worse on IFOS and alopecia, related in extent to dose, was seen in both arms. Other side-effects, such as hematuria or rises in serum creatinine and encephalopathy, were infrequent and mild. A higher response rate with less myelosuppression suggests that IFOS may have advantages over CYCLO in combination therapy.

We conducted parallel phase II trials of cimetidine as a single agent and the combination N-phosphonacetyl-L-aspartate (PALA) plus L-alanosine among 40 previously untreated patients with biopsy-proven, measurable disseminated malignant melanoma. We did not design the trial to be a comparative assessment of the two regimens. Among 19 patients treated with cimetidine, 300 mg orally four times daily, there was one complete response of extensive pleural and pulmonary metastases for 16+ months and two partial regressions of soft tissue lesions for 7 and 21+ months, respectively. Among 21 patients treated with the combination regimen, there was only one partial response in soft tissue for 1 month. The median times to progression and death were 1.4 and 6 months, respectively, for cimetidine, and 1.3 and 4 months, respectively, from the combination of PALA plus L-alanosine. Among patients who progressed on initial treatment, there were no responses in 12 who received crossover therapy with cimetidine and 11 with the combination regimen. Two patients treated with the combination program had severe stomatitis, two developed renal failure, and one had severe leukopenia and thrombocytopenia. Recognizing the limitations of small sample size, these early observations suggest that cimetidine may have intriguing implications in the management of disseminated malignant melanoma.
