The efficacy of two chemotherapy regimens for recurrent and inoperable squamous cell carcinoma of the head and neck is reported. All patients had failed prior surgery and/or radiotherapy. 23 patients (group A) were treated with Cisplatin 120 mg/m2 and Adriamycin 60 mg/m2. 21/23 were evaluable for tumour response. The overall response rate (RR) was 28.5% (6/21, 2 CR and 4 PR). Methotrexate 250 mg/m2 with Leucovorin-Rescue 5 X 10 mg/m2 and 5-Fluorouracil 600 mg/m2 were administered to 28 patients. In 26 evaluable patients a RR of 38.4% (10/26, 5 CR and 5 PR) was achieved. The responders in groups A and B had a median survival of 98 and 85.5 weeks respectively and the non-responders 27 weeks in both groups. Nausea, vomiting and alopecia were common and severe in the DDP/ADM group. The major toxic effect of MTX/5-FU was neutropenia with two associated deaths from septicemia, although subjective side-effects were almost completely absent. MTX/5-FU can be recommended for the palliative treatment of recurrent squamous head and neck cancer because of an acceptable response rate, good subjective tolerance and the possibility of outpatient treatment.

Sixteen patients with advanced AIDS-related Kaposi's sarcoma received liposomal doxorubicin (Doxil, Liposome Technology, Menlo Park, California) at 20 mg/m2 every 2 or 3 weeks in an open label study, and were evaluated for efficacy and toxicity. Eleven patients achieved a partial remission and five had stable disease. The median time to achieve a maximum response was two cycles (range 1-3) and the median duration of response was 14 weeks (range 6-30). Myelosuppression was the commonest adverse event; one patient was withdrawn because of neutropenia. Other adverse events were uncommon and mild. Liposomal doxorubicin is an effective and safe single agent treatment for advanced AIDs-related Kaposi's sarcoma.

In Japan, 5-FU/5-FU derivatives or the combination therapy of CAF (cyclophosphamide, CPA; adriamycin, ADM; 5-fluorouracil; 5-FU) have been commonly used for the adjuvant treatment of breast cancer. Recently, a combination of CEF (CPA; Epirubicin, EPI; 5-FU) has come to the stage of adjuvant setting, because the cardiotoxicity was reduced in EPI. In this study, we investigated the feasibility of 6 cycles of CEF (CPA 700 mg/m2, EPI 70 mg/m2, 5-FU 700 mg/m2; day 1 iv every 3-4 weeks) in the adjuvant treatment of primary breast cancer patients with nodal involvements. All 12 patients completed 6 cycles of CEF within 8 months. The median treatment duration was 6.2 months. More than Grade III side effects of neutropenia, nausea/vomiting and alopecia were observed in 7/12 (58.3%), 5/12 (41.7%) and 12/12 (100%), respectively. No serious side effects, including cardiotoxicity, were shown. CEF seems to be feasible regimen as an adjuvant treatment for breast cancer.

CPT-11 + ADM therapy (CPT-11 40 mg/body x 2 days; Day 1 & 2, combined with ADM 20 to 60 mg/body x 1 day; Day 3) was given to four patients with relapsed and advanced non-Hodgkin's lymphoma, which was refractory to conventional chemotherapies. The symptoms of the patients at the beginning of CPT-11 + ADM therapy were fever (in two cases), dyspnea due to pleural effusion (in two), severe backache (in one), and jaundice with splenomegaly (in one). Their Karnofsky performance scales were 20 or 30%. Soon after the initiation of CPT-11 + ADM therapy, their clinical conditions improved dramatically, and they obtained a partial remission lasting 3.5 to 9 months. During the period of controlling lymphomas by this therapy, all patients had some time at home for 2 to 8 months. The adverse effects were vomiting, diarrhea, neutropenia and thrombocytopenia, but no lethal infection or hemorrhage was seen. We conclude that CPT-11 + ADM therapy is very useful for improvement of QOL and life prolongation of patients with non-Hodgkin's lymphoma, which is refractory to conventional chemotherapies and is even disseminated.

The aim of this study was to define the maximum tolerated dose (MTD) of paclitaxel (TAX) in combination with doxorubicin (ADM). To evaluate the efficacy and tolerability of this combination, TAX was administered in escalating doses of 30 mg/m2, starting from 120 mg/m2, by 1 hour continuous infusion, per group of three patients; ADM was administered at a fixed dose of 50 mg/m2, 24 hours before administering TAX (phase 1). The combination was recycled every 3 weeks. In phase II, TAX was administered at the MTD defined in phase I. Thirty-six women were enrolled. The MTD of TAX was 220 mg/m2. Objective responses were observed in 28/34 (82%) assessable patients. The median progression-free survival was 11.8 months and overall survival 27.8 months. The main clinical toxicity was neutropenia (grade III-IV) of short duration (94%). Two patients developed cardiac toxicity. The combination TAX+ADM is very effective in advanced breast cancer.

Doxil is a liposomal preparation of doxorubicin that results in prolonged pharmacologic exposure in vivo to the active agent. We sought to test the hypothesis that this new formulation would result in improved efficacy in patients with colorectal cancer. Patients with advanced colorectal cancer who had received prior therapy were eligible for the trial. Treatment consisted of Doxil 45 mg/m2 intravenously every 3 weeks. Seventeen patients entered the trial and they received a median of two cycles of treatment. None of the patients had a partial response to treatment. Stable disease was the best response, and one patient received therapy for 17 cycles before her disease progressed. The therapy was well tolerated, with only two patients having the dose decreased because of hand-foot syndrome. Four patients experienced allergic reactions during the infusion, but with appropriate premedication and slowing of the infusion, treatment was able to be resumed without difficulty. No greater than grade I neutropenia or thrombocytopenia developed in any patient. Although Doxil was well tolerated at this dose and schedule, it was not an active agent in this group of patients. Doxil alone or in combination with other agents is worthy of further study in cancers responsive to doxorubicin.

Vestar has asked for a second time for Food and Drug Administration (FDA) approval of DaunoXome, a liposomal daunorubicin, for the treatment of patients with systemic Kaposi's Sarcoma (KS) based on results from a large phase III trial. Overall response rates were lower than expected in this trial, with only 23 percent responding to DaunoXome, and there were slightly more than expected cases of reported neutropenia. However, incidence of toxicity such as hair loss, fatigue, and neuropathy were significantly lower. One other liposomal anthracycline, Doxil, has also been recommended for approval. No trials as yet have been done to compare the two drugs' effectiveness, although quality-of-life issues make these drugs attractive candidates.

While there have been significant advances in first-line chemotherapy for advanced ovarian cancer, most patients still relapse with drug-resistant disease. For patients refractory to the two most active agents (platinum and paclitaxel), there are few salvage regimens that possess significant clinical activity together with minimal treatment-related toxicities. Caelyx is a new treatment for advanced ovarian cancer, which delivers doxorubicin encapsulated in long-circulating Stealth liposomes, resulting in a prolonged circulation and enhanced tumour targeting of the drug, together with a markedly different safety profile compared with native doxorubicin. Recent phase II clinical trials in relapsed ovarian cancer have demonstrated efficacy in patients with platinum-refractory disease (defined as progression on or relapse within 6 months of previous therapy). In those with combined platinum/paclitaxel-refractory disease, the response rate was 14.5% (95% Confidence Interval (CI): 7.8-21.4%), with many patients demonstrating a prolonged duration of response of beyond 6 months. The most frequent severe (grade 3/4) toxicity with Caelyx was palmar-plantar erythrodysesthesia (PPE), which occurred in 25% of patients and was managed by dose modification or lengthening the treatment cycle. The incidence of neutropenia and alopecia was much reduced, and the cardiac safety profile was also improved compared with equivalent cumulative anthracycline doses for native doxorubicin. In summary, the evidence of clinical efficacy in patients with platinum-refractory ovarian cancer together with an improved safety profile are all strongly supportive of a positive benefit-risk profile for Caelyx in the treatment of advanced ovarian cancer following failure of first-line platinum-based therapy

Standard chemotherapy for advanced epithelial ovarian cancer is a combination of platinum-paclitaxel. One strategy to improve the outcome for patients is to add other agents to standard therapy. Doxil is active in relapsed disease and has a response rate of 25% in platinum-resistant relapsed disease. A dose finding study of doxil-carboplatin-paclitaxel was therefore undertaken in women receiving first-line therapy. Thirty-one women with epithelial ovarian cancer or mixed Mullerian tumours of the ovary were enrolled. The doses of carboplatin, paclitaxel and doxil were as follows: carboplatin AUC 5 and 6; paclitaxel, 135 and 175 mg m(-2); doxil 20, 30, 40 and 50 mg m(-2). Schedules examined included treatment cycles of 21 and 28 days, and an alternating schedule of carboplatin-paclitaxel (q 21) with doxil being administered every other course (q 42). The dose-limiting toxicities were found to be neutropenia, stomatitis and palmar plantar syndrome and the maximum tolerated dose was defined as; carboplatin AUC 5, paclitaxel 175 mg m(-2) and doxil 30 mg m(-2) q 21. Reducing the paclitaxel dose to 135 mg m(-2) did not allow the doxil dose to be increased. Delivering doxil on alternate cycles at doses of 40 and 50 mg m(-2) also resulted in dose-limiting toxicities. The recommended doses for phase II/III trials are carboplatin AUC 6, paclitaxel 175 mg m(-2), doxil 30 mg m(-2) q 28 or carboplatin AUC 5, paclitaxel 175 mg m(-2), doxil 20 mg m(-2) q 21. Grade 3/4 haematologic toxicity was common at the recommended phase II doses but was short lived and not clinically important and non-haematologic toxicities were generally mild and consisted of nausea, paraesthesiae, stomatitis and palmar plantar syndrome.

The aim of this study was to determine the maximum tolerated dose (MTD) and the dose-limiting toxicities (DLT) of a weekly administration of paclitaxel and pegylated liposomal doxorubicin (Caelyx; Schering Plough Pharmaceutical) in patients with advanced solid tumours. 19 pretreated patients with solid tumours received escalated doses of pegylated liposomal doxorubicin (6-12 mg/m(2)) as a 1-h intravenous (i.v.) infusion followed by a fixed dose of paclitaxel (80 mg/m(2)) weekly for 4 consecutive weeks in cycles of 6 weeks. DLT was defined as grade 4 neutropenia or thrombocytopenia, febrile neutropenia, grades 3 or 4 non-haematological toxicity or treatment delay due to unresolved toxicity during cycle 1. The MTD was reached at the dose of pegylated liposomal doxorubicin of 10 mg/m(2)/week and paclitaxel of 80 mg/m(2)/week. The DLTs were treatment delay due to grade 3 neutropenia and grade 3 diarrhoea. A total of 55 chemotherapy cycles were administered, and grades 3-4 neutropenia occurred in seven cycles (13%); the non-haematological toxicity was mild with grades 2/3 diarrhoea occurring in 4 (7%), grades 2-4 asthenia in 11 (20%) and grade 2 mucositis in 7 (13%) cycles. There was no case with more than a 10% LVEF decrease after a median of 3 (range 2-6) administered cycles/patients. One patient with breast cancer and 1 with ovarian cancer experienced a major partial response. The weekly administration of pegylated liposomal doxorubicin at the dose of 10 mg/m(2) in combination with paclitaxel at the dose of 80 mg/m(2) for 4 consecutive weeks, in cycles of 6 weeks which represent the recommended doses for further phase II studies, is a well tolerated regimen, which merits further evaluation in tumours known to be sensitive to taxanes and/or anthracyclines.
