To determine the efficacy and toxicity of cis-dichlorodiammineplatinum(II) (DDP) by a continuous iv infusion (CIVI) schedule, 34 patients with a variety of solid tumors were studied. All patients were refractory to prior chemotherapy and received a loading dose of 5 mg/m2 of DDP iv followed by 20 mg/m2 by CIVI daily for 5 days. In 25 evaluable patients, there were four (16%) complete or partial responders, nine (25%) with stable disease, and 12 (48%) with tumor progression. One complete and one partial remission were seen in two patients with disseminated basal cell carcinoma, with partial responses also seen in cervical and head and neck squamous cancer. Patients experienced renal damage (21%) and audiotoxicity (10%). Nausea and vomiting was severe in only 6%. DDP by CIVI appears to have comparable toxicity to DDP administered by other schedules; however, the diminished gastrointestinal toxicity makes the drug better tolerated by patients for whom the inconvenience of a 5-day hospitalization is less than that caused by the nausea and vomiting of rapid infusion programs.

Between June 1982 and July 1990, 55 patients (41 with bladder cancers and 14 with renal pelvic or ureteral cancers) who had undergone radical extirpative surgery and/or node dissection for pathological stage pT2-4 and/or nodal disease received adjuvant chemotherapy consisting of cisplatin alone or in combination with other agents. In all, 26 of the bladder-cancer patients also received preoperative chemotherapy consisting of arterial infusion of cisplatin, mitomycin C, and Adriamycin. Adjuvant chemotherapy was performed according to the following protocol. Between June 1982 and July 1987, 30-50 mg/m2 cisplatin either alone or in combination with Adriamycin and 5-fluorouracil (CAF) was given to 35 patients in an induction and maintenance setting for 1 year. After July 1987, short-course cisplatin (70 mg/m2) or cisplatin, etoposide, and Adriamycin combination chemotherapy (CVA) was given to 20 patients. Of the 55 patients, 38 are alive and show no evidence of disease, three are alive with disease, 13 have died of their disease, and 1 has died of an unrelated cause. The 5-year survival of all patients was 65.1%. The survival of the 20 patients who were treated after July 1987 was better than that of the 35 patients who were treated before June 1987. Local recurrence and/or distant dissemination occurred in 16 patients, 13 of whom died of cancer progression. Nausea and vomiting and anorexia occurred in most patients during the administration of cisplatin. Mild to moderate myelosuppression developed in patients who received CAF or CVA combination chemotherapy. Although adjuvant chemotherapy combined with radical surgery seemed to be effective in cases with a pathological stage of pT3a or less, more intensive pre- or postoperative chemotherapy is needed to improve the poor prognosis of patients with deeply invasive uroepithelial cancer.

The continuous 24-h infusion of ifosfamide (IFX) with mesna was studied in 44 patients with therapy-resistant or relapsing ovarian cancer. All patients had stage III disease and had been pretreated with at least one combination comprising an alkylating agent and a cisplatin analogue (22, with one combination; 16, with two; and 6, with three or more). The median number of IFX cycles received was two. Of 40 evaluable patients, 2 achieved a complete response, 5 showed a partial response and 6 had stable disease. A total of 27 patients had tumor progression after one or two treatment cycles. All seven responders had responded to previous treatment for a median duration of 5 months (range, 5-41 months). No patients who progressed during alkylating-agent treatment responded to IFX given subsequently. The median progression-free period was 6 months (range, 4-12 months), and the median overall survival was only 6 months, indicating the advanced stage of disease in these patients. The median overall survival in progressive patients was 5 months (range 2-13+ months) and that in the remaining group was 13 months (ranges 3(+)-24 months) (P less than 0.05). This treatment was moderately well tolerated. Grade 3 nausea and vomiting occurred in 27% of cycles and grade 3-4 leukopenia was observed in 47%, but thrombocytopenia was hardly ever found. In eight patients there was a deterioration of renal function. Among a total of 131 cycles, the dose was reduced for only 9 due to myelotoxicity and for 3 due to nephrotoxicity. IFX seems to be active only in patients who have relapsed after responding to previous cytotoxic treatment.

Thirteen previously untreated patients with extensive small-cell lung cancer (SCLC) were treated with the investigational agent amonafide in a dose of 300 mg/m2 intravenously (IV) over 1 hour daily for 5 consecutive days. No responses were seen in 12 eligible patients. Myelosuppression was only occasionally seen. Other toxicities included diaphoresis, chest pain, local irritation at the injection site, arthralgias, nausea and vomiting, and neuromuscular problems. There were two early deaths, both attributable to tumor progression with resultant obstruction of a vital structure. Ten patients crossed over to alternate active therapy (etoposide [VP-16]-cisplatin) and five responded. The median survival time (MST) of the whole group of treated patients was 31 weeks. In future trials of investigational new drugs in previously untreated SCLC, we recommend that patients with the following characteristics be excluded: Eastern Cooperative Oncology Group (ECOG) performance status 2, 3, and 4; superior vena cava (SVC) obstruction; any major paraneoplastic syndrome; serious comorbid illness; and extensive hepatic involvement by tumor. The trial design should include prompt crossover to active alternative therapy, such as VP-16 and cisplatin, for disease progression or for failure to respond after two treatment cycles. Also, the trial design should use an early stopping rule based on interest in identifying only very active agents with a minimum response rate of 30%.

Forty-seven patients with advanced non-small cell lung cancer (NSCLC) were treated in a multicentre phase II study with pirarubicin (THP), 4'-O-tetrahydropyranyl-doxorubicin using a dosage of 70 mg/m2 every 3 weeks. The median age of the patients was 59 years (range 45-70) and the performance status grade 0-2 (WHO). Thirty-eight patients had stage IV and 9 stage III (UICC). Twenty-six patients had an adenocarcinoma. 19 a squamous cell carcinoma, and 2 a polymorphocellular carcinoma. Six out of 45 evaluable patients achieved a partial remission leading to an overall response rate of 13%. Eighteen patients showed no change (NC), 12 were progressive (PD), 2 patients had early progression (EP), and 7 patients died during the first course with clinical signs of tumor progression (early death). The median survival time was 4.6 months. Leukocytopenia and thrombocytopenia (WHO grade 4) was experienced in 8.5% and 2.1%, nausea and vomiting (grade 2 and 3) by 32% of the patients. There was no cardiotoxicity or other severe side effects. Pirarubicin has only a moderate antineoplastic activity in patients with advanced NSCLC. Observed response rates are similar to those reported for doxorubicin, but the toxic side effects are milder.

In a phase II trial 46 patients with advanced gastric carcinoma were treated with FEM combination chemotherapy (5-fluorouracil, 4-epidoxorubicin and mitomycin C) in which 4-epidoxorubicin was administered by escalated dose and split course (FEM II). Twenty-nine patients with measurable disease were evaluable for response. One complete remission and 7 partial remissions were achieved, suggesting an overall response rate of 28%; 2 minimal responses (7%) and 9 patients with no change were observed (31%); 10 patients had tumor progression (34%). Median survival time for all patients was 6.2 months, for patients with CR + PR + MR 16.2 months, for patients with no change 8.4 months, and with tumor progression 3.5 months. WHO grade 2 and 3 leukopenia appeared in 6%, thrombocytopenia in 0% and alopecia in 27% of the patients after the first cycle. Nausea and vomiting grade 2 and 3 were seen in 21%. Comparing these results with our earlier data achieved with FEM I, FEM II showed a tendency towards better response and survival, and subjective toxicity (nausea/vomiting) was significantly reduced. Therefore, in our opinion FEM II is preferable for practical use.

Mitoxantrone is a new effective antineoplastic agent with activity against a wide range of tumors. Compared with the anthracycline drugs doxo- and daunorubicin, it exhibits a clearly lower toxicity and, most importantly, a reduced cardiotoxicity. The analysis of the side-effects recorded after accidental overdosage of the drug gives additional insight into its tolerability. Here we describe our observations in three patients who inadvertently received 100 mg m-2 (two pts) and 183 mg m-2 (one pt) as single slow bolus injections. The main side-effects were moderate nausea and vomiting, shaking chills, and profound but reversible neutro- and thrombocytopenia. There was no immediate cardiac toxicity. One patient with extensive previous daunomycin exposure developed congestive heart failure after 4 months. Two patients were not evaluable for late cardiac complications because of early death due to tumor progression.

To augment the antitumor effect of high-dose melphalan and determine pharmacokinetics we conducted a phase I trial of escalating doses of high-dose IV melphalan with the chemosensitizer misonidazole for patients with advanced colorectal carcinoma. Fourteen patients with modified Dukes D adenocarcinoma of the colorectum were treated with a single course of melphalan (40-60 mg/m2 i.v. bolus q.d. X 3 days) and misonidazole (1-3 g/m2 p.o. q.d. X 3 days) followed by autologous bone marrow transplantation. Toxicity consisted of severe myelosuppression, moderate nausea and vomiting, and mild mucositis and diarrhea. One patient developed unexplained renal tubular acidosis, and a diffuse encephalopathy occurred in another patient. Three patients died within the first 30 days after the start of treatment, two due to tumor progression and one due to sepsis and disseminated intravascular coagulation-induced intracerebral hemorrhage. Six of 14 patients achieved a partial response, and the median response duration was 4 months (range 3-10 months). Analysis of misonidazole serum concentrations showed similar pharmacokinetics to those previously reported, suggesting no significant drug interaction with intravenous melphalan. Mean peak serum concentrations ranged from 81.8 micrograms/ml to 115.2 micrograms/ml at the second and third misonidazole dose levels, which approximate those known to provide effective chemosensitization with melphalan in animal models. In this phase I study, we showed that maximally tolerated doses of intravenous melphalan can safely be combined with oral misonidazole. In view of the large volumes of oral misonidazole required at the highest dose level, subsequent studies to determine the maximally tolerated dose of misonidazole should employ the intravenous form.

Twenty patients with focal malignant obstruction of the major bile ducts (6 cholangiocarcinoma, 8 colorectal, 3 hepatoma, 2 unknown primary, and 1 gastric cancer) were treated on a protocol examining the toxicity and efficacy in relieving jaundice of external beam radiation therapy (4500 cGy in 300 cGy fractions) combined with continuous hepatic arterial (15 patients) or peripheral venous (5 patients) fluorouracil infusion. Toxicity of this regimen consisted of anorexia with mild nausea and vomiting in 55% of patients and gastric ulceration (responsive to medical management) in 15% of patients. One patient exhibited transient grade 2 hepatic toxicity and one had asymptomatic grade 4 leukopenia. Of 14 patients treated without prior biliary drainage, 8 exhibited a decrease in bilirubin levels from a mean of 14.5 mg/dl to 1.5 mg/dl. Four of six patients with biliary drainage catheters at the start of treatment were able to have them removed without reobstruction. For the 8 responding patients among those who did not have cholangiocarcinomas, the median response duration was 5 months with a median survival from treatment of 6.5 months. For the 4 responding patients with cholangiocarcinoma, the median response duration was 16 months with a median survival from treatment of 20 months. All responders did not have a return of jaundice due to reobstruction of the major ducts (until death or to the present). All responders who have died did so due to tumor progression outside of the treated field except for one who died of unrelated causes. The mean number of proven or presumed episodes of cholangitis per patient was virtually identical in those without (1.8) and those with stents/tubes (1.4, p = 0.561). This regionally focused combined modality cytotoxic therapy was able to relieve obstruction in the majority of patients without excess morbidity (including a lack of any detectable increase in sepsis). Thus, it appears feasible to consider randomized studies of this cytotoxic approach versus standard mechanical drainage procedures to define the relative risks and benefits of each.

From June 1982 through December 1985, 25 patients who had undergone radical cystectomy with pelvic node dissection for pathologic stage-pT3 or -pT4 and/or N+ disease received adjuvant chemotherapy involving the injection of cis-platinum alone or in combination with adriamycin and 5-fluorouracil (CAF). Thirteen patients also received preoperative adjuvant chemotherapy involving the infusion of cis-platinum, adriamycin, and mitomycin C into the bilateral internal iliac arteries. Postoperative adjuvant chemotherapy was performed using the following two protocols. Protocol 1 (18 cases) consisted of cis-platinum alone being administered every week for 3 weeks and then every month for 1 year. In protocol 2 (7 cases), cisplatinum, adriamycin, and 5-fluorouracil were administered at 3-week intervals on three occasions and then every month for 1 year. Eighteen patients were still alive with no evidence of disease after an average of 26 months. One patient died as a result of factors unrelated to cancer. Local recurrence and distant metastasis occurred in 6 patients, of whom 3 were still alive for an average of 20.7 months. Three patients died of cancer progression after 9, 19, and 21 months. The survival rate for all 25 patients at 50 months was 77%. Nausea and vomiting occurred in most patients during the administration of cis-platinum. Mild myelosuppression developed in a few patients subjected to protocol 2. Our results indicate that adjuvant chemotherapy consisting of the administration of cis-platinum alone or in combination with other chemotherapeutic agents appears to be effective in patients with invasive bladder cancer.
