During the 9-year period from 1982 to 1991, 72 patients with melanoma were treated with a 5-day quadruple drug chemotherapy regime (BELD) comprising bleomycin, vindesine (Eldesine), CCNU (Lomustine) and DTIC. Forty-three patients had stage III melanoma, 34 of whom had evaluable disease. Of these 34, six (17.6%) achieved a complete response (CR), eight (23.5%) had a partial response (PR), five (14.7%) had stabilized disease (SD) and 15 (44.1%) had progressive disease (PD). Overall median survival of stage III melanoma patients was 38 weeks. Median survival of responders (CR + PR) was 47 weeks and 21 weeks for non-responders (SD + PD) (P < 0.005). Median follow-up time was 38 weeks. Following these encouraging results, 30 patients with stage II melanoma received BELD chemotherapy as adjuvant therapy after regional node dissection and clearance. Adjuvant BELD chemotherapy did not alter survival in these patients. BELD combination chemotherapy is well-tolerated, the main problems being nausea, vomiting, and leucopenia. We have maintained a combined response rate (CR + PR) of 41.1% for stage III disease. This is comparable with other combination chemotherapy regimes, which have as yet not been superseded by the newer biological therapies.

The aim of this pilot study was to estimate the toxicity and response rate of an alternating chemotherapeutic program in chemotherapy-naive metastatic breast cancer patients. Treatment consisted of regimen A (given days 1-28): cyclophosphamide 100 mg/m2 PO days 1-14, doxorubicin 30 mg/m2 i.v. days 1 and 8, and 5-fluorouracil 500 mg/m2 i.v. days 1 and 8 (CAF regimen); regimen B (given days 29-56): dibromodulcitol 135 mg/m2 p.o. days 30-39, mitoxantrone 9 mg/m2 i.v. day 29, and vincristine 1.2 mg/m2 i.v. (maximum 2.0 mg) day 29 (DMV regimen); and regimen C (given days 57-84): thiotepa 12 mg/m2, doxorubicin 45 mg/m2 and vinblastine 4.5 mg/m2 all i.v. on day 57. There were 27 eligible patients with a median age of 51 years (range 34-78). On 14 episodes the leukocyte count fell to less than 1 X 10(9)/L during the first six cycles of treatment (14% of 99 cycles). There were no treatment-related deaths. Common non-life-threatening toxicities included thrombocytopenia, anemia, vomiting, and alopecia. Despite having no drugs in common, the leukocyte and platelet nadirs after CAF correlated with the nadir counts after DMV (r values of 0.6829 and 0.5892, respectively; p = 0.01). Among the 23 patients with measurable and/or evaluable disease there were five complete responses (22%) and nine partial responses (39%), with a median time to treatment failure of 29 weeks. The overall median survival was 19 months.

A randomized trial was performed to determine relative efficacy and toxicity of two first-line combination chemotherapy regimens in women with metastatic breast cancer: CFP (cyclophosphamide, 5-fluorouracil, prednisone) and CMFP (cyclophosphamide, 5-fluorouracil, methotrexate, prednisone). Both regimens have reported efficacy in this setting but differ in dosages and scheduling of the agents they have in common. Three hundred thirty-six women with no prior chemotherapy for metastatic disease were eligible and evaluable, and 309 had either measurable or evaluable disease and were assessable for objective response. Responses were seen in 65 of 153 (42%) on CFP and 83 of 156 (53%) on CMFP (two-sided P = 0.06). Median durations of response were 7.1 months for CFP and 8.5 months for CMFP (log-rank, two-sided P = 0.67). Considering all 336 patients, the median times to disease progression were 4.7 months for CFP and 6.2 months for CMFP (log-rank P = 0.31) and median survivals were 15.2 and 14.9 months, respectively (log-rank P = 0.88). Covariate analysis did not alter these findings. Median leukocyte nadirs were 1800 for CFP and 1500 for CMFP, with 22% and 21%, respectively, having nadirs less than 1000/microliters. Emesis was more frequent on CFP (49%) than on CMFP (26%) but was severe in only 7% and 5%, respectively. It is concluded that despite a higher response rate on CMFP and some differences in toxicities including a higher reported incidence of emesis on CFP, there was no substantial difference in efficacy or tolerability between the two regimens.

The survival benefit of combination chemotherapy to patients with advanced non-small-cell carcinoma of the lung (NSCLC) is controversial. To study this question, the National Cancer Institute of Canada (NCIC) Clinical Trials Group conducted a prospective randomized trial comparing best supportive care (BSC) to two chemotherapy regimens, vindesine and cisplatin (VP), and cyclophosphamide, doxorubicin, and cisplatin (CAP). Between February 1983 and January 1986, 23 centers across Canada entered 251 patients on study. Eighteen centers participated in the three-arm schema (150 patients); centers choosing not to participate in a study with a no-chemotherapy arm followed a two-arm schema comparing VP with CAP (101 additional patients). Altogether, 233 patients were eligible. Patients had measurable or evaluable disease, with either distant metastases (82.5%) or bulky limited disease considered inoperable or unsuitable for radical radiotherapy. The treatment groups were comparable in terms of age, sex, performance status, histology, disease extent, and weight loss. The overall response rates (complete response [CR] plus partial response [PR]) on the chemotherapy arms were CAP, 15.3%, and VP, 25.3% (P = .06). Patients on the three-arm portion of the trial had a median survival of 32.6 weeks when treated with VP, 24.7 weeks with CAP, and 17 weeks with BSC. The significance of the differences in survival, adjusted for prognostic factors, is as follows: chemotherapy v BSC, P = .02; VP v BSC, P = .01; and CAP v BSC, P = .05. Toxicity on the chemotherapy arms was significant, with leukopenia of severe or greater degree occurring in 37.8% (CAP) and 40.0% (VP), severe vomiting in 12.2% (CAP) and 23.3% (VP), and severe neurotoxicity in 15.6% (VP).

The possible synergism of cisplatin (P) and 5-fluorouracil was studied in 38 consecutive patients with advanced or metastatic colorectal carcinoma. Cisplatin 60 mg/m2 i.v.q. 4 weeks and fluorouracil 600 mg/m2 i.v. weekly were administered for at least 2 cycles, on an out-patient basis, to 24 males and 14 females with a median age of 57 years and a median PS of 80 (Karnofsky). Evaluable lesions were: primary unresectable tumor in 2 patients, local recurrence in 11, liver, lung, bone and soft tissue metastases in 21, 7, 2 and 3 patients respectively. With a median number of 3 cycles administered to 35 evaluable patients, 6 partial responses, 16 unchanged and 13 progressions were observed. Responses were observed in the liver (2 patients), lungs (1) and soft tissues (3). Median remission duration was 15 weeks, median duration of 'unchanged' was 12 weeks. The overall median survival was 24 weeks (30.5 weeks for responders and 22.5 weeks for non-responders). Six patients were pretreated with chemotherapy not containing cisplatin (mainly adjuvant 5-FU). None of them responded. Toxicity was very tolerable with moderate nausea, vomiting and alopecia in the majority of the patients; bone marrow toxicity was generally mild with no blood transfusions required, no complications of myelosuppression (sepsis or bleeding) and no chemotherapy-related deaths. In this experience the combination of low dose cisplatin with fluorouracil, does not appear to significantly enhance 5-FU toxicity and the response rate is not superior to that reported with 5-FU alone. However, better designed schedule combinations with optimal doses, sequences and exposure time of the 2-drug regimen, seem necessary to obtain the biochemical events that support the potentiation.

The clinical pharmacology and toxicity of a novel anthracycline derivative, 4'-O-tetrahydropyranyladriamycin (THP-adriamycin), was investigated in patients with advanced malignant diseases. The starting dose was 30 mg/m2 which was escalated by increments of 10 mg/m2. Twelve patients with a median age of 42 (range, 19-69) years and a median Eastern Cooperative Oncology Group performance score of 2 (range, 1-2) were entered into the study. The diagnoses included four testicular cancers, two breast cancers, two small cell lung cancers, two acute myeloid leukemias, one colon cancer, and one hemangiosarcoma. THP-adriamycin was given as an i.v. bolus injection every 3 weeks. Evaluable were 18 courses for general toxicity, 16 courses for hematological toxicity, and 16 courses for pharmacokinetics. THP-adriamycin had a short initial half-life of 1.4 +/- 0.3 min (mean +/- SD) due to rapid cellular uptake. Peak concentrations in unseparated blood cells were reached 5 min after drug injection and remained higher than in plasma throughout the observation period of 72 h. The half-lives of THP-adriamycin in plasma were 19 +/- 2.8 min in an intermediate and 13 +/- 1.6 h in the terminal phase. A linear correlation was observed between the dose and the areas under the concentration curves for THP-adriamycin in plasma (r2 = 0.97) and blood cells (r2 = 0.99). The volume of distribution was 2124 +/- 221 liters/m2 and the total clearance rate 115 +/- 11 liters/m2h. THP-adriamycin was metabolized to Adriamycin, THP-adriamycinol, and adriamycinol. The major metabolite was Adriamycin with a terminal half-life in plasma of 33 +/- 10 h. The area under the curve of Adriamycin was also correlated to the administered dose (r2 = 0.96). Since excessive peak concentrations of Adriamycin were avoided, the treatment with THP-adriamycin might be an alternative to continuous infusions or weekly administrations. The maximum tolerated dose was 70 mg/m2, and the dose-limiting toxicities were leukopenia and thrombocytopenia. Anemia, nausea, and vomiting were mild to moderate, and no other toxicity was observed. All side effects were dose dependent and reversible. In a patient with breast cancer, a disease stabilization was achieved lasting for 9 weeks. No objective remission was observed. We suggest 60 mg/m2 in pretreated or poor risk and 70 mg/m2 in untreated or good risk patients every 3 weeks for further clinical trials.

Antiemetic effects of perphenazine and prochlorperazine, both administered by continuous i.v. infusion after a loading dose, were compared in patients receiving cisplatin. Study subjects were 6 men and 13 women for whom other antiemetic therapy had failed; each patient was studied during two courses of cisplatin therapy. Patients were randomly selected to receive either perphenazine or prochlorperazine during the first course; for the second course, each received the other antiemetic. During drug administration, nausea, retching, vomiting, and side effects of the antiemetic were recorded hourly by the patient and concurrently by a pharmacist observer (both blinded). Each patient's scores on nausea, retching, and vomiting were compared by drug and by treatment sequence. Evaluable data for 17 patients showed that aggregate differences between responses to the two drugs were not significant. Fourteen patients had significantly less nausea, retching, and vomiting during the second course of treatment. Few side effects were reported. Nervousness was experienced with prochlorperazine in four patients and perphenazine in one, and drowsiness occurred with prochlorperazine in four patients and perphenazine in three. Perphenazine and prochlorperazine, when given in equal doses and administered by continuous i.v. infusion after a loading dose, were equally effective in controlling nausea and vomiting associated with cisplatin therapy.

Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) is an effective drug in the treatment of metastatic breast cancer (MBC). In the salvage setting, 5-fluorouracil (5-FU) and folinic acid have proved to be effective against MBC as well. Recent preclinical data suggest that paclitaxel plus 5-FU has additive cytotoxicity. Given these observations, we initiated a phase II trial in which 38 women with MBC have been treated with a combination of all three drugs. All patients are currently evaluable for toxicity and 34 are evaluable for response. All women had histologically proven and assessable disease. Patients with prior exposure to paclitaxel were ineligible. Patient characteristics include a median age of 51 years (age range, 31 to 73 years) and a median performance status of 1 (range, 0 to 2). Thirty-three patients have received prior chemotherapy, of whom 23 had adjuvant chemotherapy only. Fifty-eight percent of the patients (22 of 38) had received prior doxorubicin or mitoxantrone; four patients had only hormonal therapy. Four patients had bone-only disease, and three patients had lymphangitic spread or cytologically positive pleural effusion as the only evaluable disease. Treatment consisted of paclitaxel 175 mg/m2 over 3 hours (day 1 only), followed by folinic acid 300 mg over 1 hour, followed by 5-FU 350 mg/m2 on days 1 to 3. Patients received standard paclitaxel premedications. To date, 175 cycles have been administered (median cycle length, 29 days; median number of cycles per patient, five). Toxicities included grade 3/4 infections in nine cycles (5%), grade 3/4 mucositis in three cycles, grade 3/4 nausea/vomiting in three cycles, grade 1 paresthesias in 12 patients (32%), alopecia 100%, and 17 cycles (10%) associated with dose reduction. Based on Cancer and Leukemia Group B toxicity criteria, arthralgia/myalgias were modest and graded mild (32 cycles), moderate (nine cycles), or severe (two cycles). There were two major hypersensitivity reactions, prompting removal of those patients from further protocol treatment. Four patients are unassessable for response due to hypersensitivity reactions (two) and unevaluable disease (two). Among the 34 patients evaluable for response, there were three complete responses, 18 partial responses, one minor response, nine stable disease, and three progressive disease (response rate, 62%). Responses were seen in patients who had received prior doxorubicin or mitoxantrone (11 of 22 patients) and in anthracycline/naive patients (10 of 16 patients). Responses were observed in all metastatic sites: soft tissue, viscera, and bone. Paclitaxel/5-FU/folinic acid appears to be an effective and well-tolerated outpatient regimen for women with MBC, even after failure of anthracycline-containing therapy.

High-dose megestrol acetate has been reported to be effective salvage therapy for women with ovarian carcinoma. The Eastern Cooperative Oncology Group performed this phase II study of oral megestrol acetate, 200 mg four times daily until disease progression, in 33 patients either with stage III or IV histologically confirmed ovarian carcinoma or with unresectable tumor in the pelvis with measurable or evaluable disease who progressed after treatment with one prior chemotherapy regimen. Thirty and 31 patients were evaluable for response and toxicity, respectively. No patient had an objective response and none had subjective improvement after a median treatment period of 1.4 months. Nausea or vomiting occurred in most patients, usually grade 1-2. Megestrol acetate is ineffective salvage therapy for patients with inoperable, previously treated ovarian carcinoma.

The cytotoxic regimen of epirubicin, cisplatin, and continuous infusional 5-fluorouracil (ECF) has demonstrated activity in a range of malignancies, including gastroesophageal, breast, and pancreatic cancers. Prolonged infusional central venous catheter (CVC) mediated therapy is not always feasible and modifications of the 5-fluorouracil (5FU) schedule have been reported. We reviewed our experience of both the standard and a modified ECF regimen in patients diagnosed with carcinoma of unknown primary site (CUPS). A retrospective analysis of all patients diagnosed with CUPS (31 adenocarcinoma and 5 poorly differentiated carcinoma) and treated with ECF between June 1994 and June 1998 was undertaken. Thirty-six patients, median age 56 (range: 24-74), were treated thrice-weekly with 50 mg/m2 epirubicin, 60 mg/m2 cisplatin, and 5-FU administered either by continuous infusion 200 mg/m2/d via a CVC (standard ECF) or as a 6-h infusion 600 mg/m2 through a peripheral venous catheter (modified ECF). Thirteen patients were treated with standard ECF and 23 received modified ECF. The median number of cycles administered was 4 (range: 1-10). Thirty-two patients had evaluable disease, seven (22%; 95% confidence interval: 8-36%) demonstrated a partial response, including three patients that received standard ECF and four treated with modified ECF. There were no complete responses. The median survival for all 36 patients was 9.0 mo. Median survival for patients treated with standard ECF was 11.7 mo as compared to 5.1 mo for the modified ECF schedule (p = 0.052). Liver involvement and elevation of serum CA19.9 were identified as possible adverse prognostic factors. Both regimens were well tolerated, with the only grade 3/4 toxicity recorded being leukopenia (four patients), nausea/vomiting (seven patients), and diarrhea (one patient). CVC complications in the standard ECF group were thrombosis (one patient) and infection (three patients). There were no treatment-related deaths. We conclude that ECF, whether modified or standard, has modest activity in the setting of CUPS. Patient survival is comparable to survival documented in previous reports of CUPS treatment. The apparent survival difference between the two ECF schedules may be the result of patient selection factors. The optimal treatment of CUPS remains unknown and can only be determined through randomized controlled trials.
