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.

Fotemustine is a new nitrosourea which has shown some efficacy on disseminated malignant melanoma (DMM) (24.2% response rate (RR) among 153 patients in a Phase II trial) but little activity on hepatic metastasis (8.8% RR). In order to improve those poor results, hepatic intra-arterial infusion (HIAI) of fotemustine was performed. After two years, thirteen patients, all in good general condition, were evaluable. Seven were pretreated and six had extrahepatic metastasis on entry into the study. All patients had a surgically implanted intra-arterial catheter. The induction cycle consisted of 100 mg/m2/week for 3-4 weeks, followed by 5 weeks rest and maintenance therapy of 100 mg/m2 every 3 weeks for stabilized or responding patients. Two complete responses (CR) (72+ and 145+ weeks) and six partial responses (PR) (7-18.5 weeks) were observed. The hepatic RR reached 61.5%. A RR of 42.8% was registered on preexisting EHM (one CR and one PR on cerebral lesions). Nevertheless, this treatment is limited by the high progression rate of 46.1% in extrahepatic disease. Toxicity was mainly hematologic (grade III-IV), comprising 36% neutropenia and 15% thrombopenia. Hepatic intra-arterial infusion of fotemustine is efficient therapy for liver metastases of DMM, but combination schedules (IV + HIA) are warranted.

Intra-arterial hepatic chemotherapy (IAHC) with adriamycin (ADM) has not increased its therapeutic index. For our preclinical studies, we selected pirarubicin (THP), an ADM derivative with faster cellular uptake. In rabbits with VX2 tumor in the liver we compared plasmatic and cellular pharmacokinetics of ADM and THP after i.v. and IAH therapy. For ADM, there were no differences in plasma and heart concentrations, with only a slight increase in tumoral levels after IAH compared to i.v. administration; on the other hand, with IAH THP, there was important reduction in systemic exposure with a major increase in tumoral drug distribution. In the phase I study, involving nine patients with implanted catheters, the starting dose of THP was 30 mg/m2 with a 10 mg/m2 intrapatient escalation every 3 weeks in the absence of toxicity. Pharmacokinetics were compared for i.v. and IAH administration in seven patients. The limiting toxicity was neutropenia and the maximal tolerated dose (MTD) ranged from 50 to 110 mg/m2. Moderate nausea-vomiting (grade 1-2) and alopecia (grade 1) occurred at the MTD. No arterial occlusion, gastroduodenal ulcer, hepatitis, or sclerosing cholangitis were seen. In the phase II study, in colorectal cancer patients (CRC) with metastasis confined to the liver, patients were enrolled until June 1990. THP (40 min infusion every 3 weeks) was initiated at 60 mg/m2 with 10 mg/m2 increment until grade 2 hematotoxicity. The median MTD was 85 mg/m2 (range of 60-120 mg/m2), and the median number of cycles was 7 (range of 2-11) with cumulated doses from 180 to 1,030 mg/m2. Grade 2-4 neutropenia was reached in 15 patients. Other toxicities included two arterial occlusions, one episode of gastritis, but no hepatic toxicity and no heart failure. Antitumor effect (in 18 patients) included 1 CR, 5 PR, 3 MR, 6 NC, and 3 PD. The median survival was 18+ months and 1-year survival was 73% +/- 12%. Seven patients had extrahepatic progression at this time. In conclusion, besides 5-FU or Fudr, THP is active in IAHC (probably in relation with high local extraction) on CRC liver metastases usually unresponsive to ADM. It can be given in an outpatient setting with minimal toxicity.

4'-O-Tetrahydropyranyl adriamycin (THP adriamycin) is a new anthracycline active as a single drug in advanced breast cancer. We have undertaken a phase II study as first-line treatment for metastatic disease with THP adriamycin day 1 = 40 mg/m2 i.v. bolus and 5-fluorouracil day 1 to day 5 = 750 mg/m2 as a continuous i.v. infusion. The dose of THP adriamycin was further escalated up to the maximal tolerated dose defined as grade 3 granulopenia for each patient. Thirty-nine patients were included, 37 being so far evaluable for toxicity and for efficacy. The mean number of cycles given was 5 (range: 2-12). The overall response rate (CR + PR) was 54% (95% CI: 37.9-70.1) and the CR rate 8%. Sites of response were as follows: lung 6/9, liver 11/18, breast 4/8, nodes 7/14, skin 3/8, bone 2/8. Neutropenia with grade 3 + 4 nadir values was observed in 70.2% of the patients according to the objective of the study. No severe thrombopenia or anemia occurred. Stomatitis grade 3 was seen in 27% and grade 4 in 3% of the patients. Alopecia grade 2 was seen in 18% and grade 3 in 9%. No other toxicity was observed. We conclude that this association is effective in metastatic breast cancer, giving few alopecia. A high response rate in liver metastases warrants further evaluation.

FC-2.15 is a new murine IgM monoclonal antibody (MAb) that recognizes previously undescribed antigens present in proliferating breast cancer cells and normal peripheral granulocytes. A phase I clinical trial was performed in 11 patients with advanced cancer (breast, 5; colon, 2; melanoma, 1; lung, 1; medullary thyroid, 1; skin squamous carcinoma, 1). FC-2.15 was administered by i.v. infusion every other day; eight patients received four infusions, two patients three infusions and one patient received two infusions. One patient received two cycles of treatment. Total doses of MAb ranged between 2.5 and 5 mg/kg. Maximal FC-2.15 serum concentrations for different patients ranged between 1.3 and 7.5 micrograms/ml, and the serum half-life (t1/2-alpha) was approximately 7-9 h. All patients developed human anti-murine antibody. The most consistent toxicity (10 of 11 patients) was a profound and selective neutropenia that occurred within 1 h after the start of each infusion and reversed within 1 h after its discontinuation. Other frequent side effects included fever and chills that were easily manageable. Only two patients needed dose reduction or treatment interruption. The patient who received two treatment cycles did not develop allergic reactions. An objective partial response, consisting of a sustained (4 months) > 50% reduction of breast carcinoma liver metastases, was observed.

Fazarabine (Arabinofuranosyl-5-azacytosine) is a synthetic pyrimidine nucleoside which combines the arabinose sugar of cytosine arabinoside with the triazine base of 5-azacytidine. It has demonstrated activity against a variety of human solid tumor xenografts including colon, lung and breast cancers. Eighteen patients with refractory metastatic colon cancer were enrolled in a phase II trial of fazarabine. The drug was administered as a 72 hr continuous infusion every 3-4 weeks; the starting dose was 2 mg/m2/hr as established in a previous phase I study. The major toxicity was neutropenia, as predicted from the phase I study. The median time to nadir for cycle 1 was 20 days, with a median granulocyte count of 437/microliters (range 36-1600/microliters); recovery was within 2-4 days, with only one incidence of fever and neutropenia in 42 cycles. Especially noted for their absence were thrombocytopenia, nausea, vomiting and stomatitis. No objective clinical responses were seen; one patient had stabilization of rapidly growing liver metastases for a period of 7 months. In view of fazarabine's narrow range of toxicities, future dose intensification trials utilizing fazarabine in combination with hematopoietic growth factors are worthy of consideration.

On the basis of preclinical data showing synergy between 5-fluorouracil (5-FU), leucovorin (LV) and IFN-alpha-2a, a phase I study was carried out to determine the maximum tolerable dose (MTD) of IFN-alpha-2a with this combination in patients with gastrointestinal malignancies. The treatment consisted of 370 mg/m2 5-FU and 200 mg/m2, LV on days 1 to 5, and IFN-alpha-2a on days 1 to 5 of the first week of chemotherapy and on days 1, 3, 5 of each subsequent week, on a 28-day cycle. Six patients with colorectal, 3 with pancreas, 2 with oesophagus, 2 with hepatocellular and one with gastric cancer were treated. At level III (5 x 10(6) U/m2) all patients experienced grade 3 or 4 toxicity during the first 56 days of treatment and the MTD was declared level II. Grade 3 toxicity comprised of anorexia, mucositis, diarrhoea, and fatigue; in one instance, grade 4 neutropenia occurred. Ten patients were evaluable for response, one patient with an oesophageal cancer had a minor response and one patient with rectal cancer and liver metastases had a radiological complete response lasting 3 months. The recommended dose for this schedule in phase II studies is 5-FU 370 mg/m2, LV 200 mg/m2, and IFN-alpha-2a 4 x 10(6) U/m2.

Taxol was administered as a 24-hour continuous infusion at 250 mg/m2 in this Phase II trial in patients with adenocarcinomas of the upper gastrointestinal tract (UGIT). Twenty-five patients were entered between July 1991 and June 1992, twenty-three were eligible and were evaluated for toxicity and twenty-two were assessable for response. There was one partial response (4.5%) in a patient with liver metastases, with a duration of 6 months. Toxicity was primarily neutropenia. Taxol as a single agent appears to have little activity in adenocarcinoma of the UGIT.

In this phase II study, 39 women (median age 51 years) with advanced breast cancer received docetaxel (75 mg m-2) intravenously over 1 h every 3 weeks as first-line chemotherapy for advanced disease, without routine premedication for hypersensitivity reactions. In 31 evaluable patients, an overall response rate of 52% (95% CI 33-70%) was achieved, including a complete response rate of 13%. The median time to first response was 12 weeks (range 3-35+), the median duration of response was 34 weeks (range 11-42+) and the median time to progression was 24 weeks (range 0-42+). Docetaxel showed considerable activity in patients with visceral involvement (52% response), including lung (67%) and liver (44%) metastases. The safety profile was acceptable. Grade 4 neutropenia occurred in 82% of patients (53% of cycles); febrile neutropenia (grade 4 neutropenia with fever > 38 degrees C, requiring antibiotics) occurred in only three (7.7%) patients (1.4% of cycles) and none of these required hospitalisation. Acute adverse events were generally well tolerated, with only two grade 3 events and no grade 4 events reported. Despite no prophylactic premedication, the incidence of acute hypersensitivity reactions was only 13%. Fluid retention was widely experienced (72% of patients) but was severe in only five (12.8%) patients and was the reason for discontinuation of treatment in 16 patients. Nevertheless, patients were able to receive a median cumulative dose of approximately 592 mg m-2 before discontinuing treatment, and the syndrome was slowly reversible after treatment withdrawal. In conclusion, docetaxel, even at a dose of 75 mg m-2, is confirmed to be an active agent in breast cancer. Compared with an earlier study of first-line docetaxel at the usual dose of 100 mg-2, it appears that 75 mg m-2 produces a lower response rate (52% vs 68%), although this still compares favourably with that of doxorubicin monotherapy in a similar patient population (43%). This difference is particularly striking in subgroups of patients with particularly poor prognostic factors, such as liver metastases or involvement of more than two organs. The incidence of fluid retention appears to be similar at the two doses and, it is likely that premedication with corticosteroids will be preferable to dose reduction for managing this adverse event.

Nasopharyngeal carcinoma (NPC) has been shown to be highly responsive to chemotherapy. The major limiting toxicity was myelotoxicity. Recently, the role of granulocyte colony-stimulating factor (G-CSF) in reducing chemotherapy-induced neutropenic sepsis has been well established. In this study, we tested whether recombinant human G-CSF (rhG-CSF) could effectively support the bone marrow function in both previously untreated and pretreated metastatic NPC patients receiving intensive chemotherapy. Twelve patients with distant metastatic disease, 5 newly diagnosed (group A) and 7 pretreated patients (group B), were enrolled to receive BEC (bleomycin, epirubicin and cisplatin), followed by rhG-CSF support (50 microg/m2 s.c. daily for 10 days) every 4 weeks for two cycles. Four patients in group A completed the treatment as scheduled while only 2 patients in group B did. After the first treatment cycle, 6 patients (50%) had grade III-IV myelosuppression. Five of the patients were from group B. The mean values of the white cell count nadir were 2,680 (range 1,200-3,700) in group A and 1,343 (range 400-2,900) in group B (p = 0.0386). Neutropenia-associated fever occurred in 7 patients, 6 of whom had received previous treatment. There were 2 deaths due to toxicity, and both patients had liver metastases within 6 months following radiation. After 24 months of follow-up, only 1 patient is still alive. Our preliminary results suggest that in previously treated metastatic NPC patients, bone marrow suppression is still the major limiting toxic side effect of aggressive chemotherapy, especially for those patients with liver recurrences within 6 months after irradiation and despite rhG-CSF support.
