Combined chemo-immuno-hormonotherapy of advanced renal cell carcinoma.

Thirty-five patients (pts.) with advanced renal cell carcinoma were treated with a combination of vinblastine (5 mg/m2/IV) plus epirubicin (50 mg/m2/IV) every 3-4 weeks, alpha-2-A-interferon (9 x 10(6) U/IM 3 times in the 1st week, then 18 x 10(6) U/IM 3 times weekly), and medroxyprogesterone acetate (2,000 mg/os/day plus 500 mg IM/week). Thirty-one patients were males and 4 were females with a median age of 63 years (range 35-75) and median performance status of 70% (range 50-90%). We observed nine partial remissions (26%) with median duration of 40 weeks (range 20-232+). Fifteen pts. had no change (43%) while 11 pts. progressed (31%). The main side-effects were: leukopenia (29/35, 83%) with median nadir of 3,100 WBC/mm3 (range 510-3,990) and fever (32/35, 91%). Thrombocytopenia occurred in 4 pts. (11%), anemia in 5 (14%), asthenia in 12 (34%), nausea/vomiting in 12 (34%), alopecia in 8 (23%) and stomatitis in 3 (8.5%). Two patients stopped the therapy with medroxyprogesterone acetate because of muscular cramps. Median survival was 65 weeks (range 6-327+). We conclude that the combination of recombinant alpha 2A-interferon-vinblastine-epirubicin and medroxyprogesterone acetate has modest but definitive activity in patients with advanced renal cell carcinoma.

Epirubicin metabolism and pharmacokinetics after conventional- and high-dose intravenous administration: a cross-over study.

In a pharmacokinetics study, six patients were treated i.v. with epirubicin (EPI) at the two dose levels of 60 and 120 mg/m2, whereas a further six patients were treated at 75 and 150 mg/m2. Both groups were studied according to a balanced cross-over design; the aim of the study was to assess the pharmacokinetic linearity of epirubicin given at high doses. Both the absolute goodness of fit and the Akaike Information Criterion (AIC) point to a linear, tricompartmental open model as the choice framework for discussing EPI plasma disposition after 16/24 administrations, independent of the delivered dose. After 8 treatments, the minimal AIC value corresponded to a nonlinear tissue-binding model. However, even in these cases, second-order effects were present only during the early minutes following treatment. In a model-independent framework, mean EPI plasma clearance was identical at the two dose levels of 60 and 120 mg/m2 (65.4 +/- 8.0 vs 65.3 +/- 13.4 l/h, P = 0.92). Both the mean residence time (MRT) and the volume of distribution at steady-state (VSS) were similar as well (MRT: 22.6 +/- 2.9 vs 24.2 +/- 3.7 h; P = 0.46; VSS: 21.3 +/- 1.5 vs 22.6 +/- 6.5 l/kg, P = 0.46). No statistically significant difference could be found in mean statistical-moment-theory parameters determined after 75- and 150-mg/m2 EPI doses (plasma clearance, PlCl: 83.4 +/- 13.5 vs 68.5 +/- 12.8 l/h, P = 0.12; MRT: 22.6 +/- 4.8 vs 21.9 +/- 3.9 h, P = 0.60; VSS: 26.7 +/- 10.5 vs 21.2 +/- 7.0 l/kg, P = 0.17). Analysis of variance also failed to reveal any significant correlation between dose and plasma clearance. However, when data relative to single patients were examined, a trend toward nonlinear drug distribution as well as a consequent increase in peripheral bioavailability could be observed in 4/6 patients of the 75-mg/m2 vs the 150-mg/m2 group.(ABSTRACT TRUNCATED AT 400 WORDS)

A phase II study of carboplatin and cyclophosphamide in advanced ovarian carcinoma.

Forty-two patients affected by either stage III and IV ovarian cancer with residual tumor after surgery or recurrent ovarian cancer entered a phase II study of the combination carboplatin 300 mg/m2 and cyclophosphamide 600 mg/m2 every 28 days. Thirty-eight patients were evaluable for response and of these 27 obtained complete or partial remission with a 71% overall remission (clinical complete remission 45%; partial remission 26%). Treatment tolerability was on the whole good. The most frequent side effects were leukopenia (76%), anemia (67%) and nausea/vomiting (60%). Thrombocytopenia was present in 31% of the patients, but nearly always to a mild degree except for one grade 4 case. No other grade 4 side effect was observed. We did not observe any cases of nephrotoxicity and only two patients complained of paresthesia. This carboplatin-cyclophosphamide combination in advanced ovarian carcinoma produces comparable results, in terms of objective responses, to those obtained with standard cisplatin-based regimens, with suggestion of a better toxicological profile.

Folinic acid plus 5-FU based chemotherapy in squamous cell carcinoma of the head and neck: Bologna experience.

BACKGROUND: The principal aim of our policy in the cytotoxic treatment of advanced squamous cell carcinoma of the head and neck (SCCHN) is to reduce toxicity, to maintain or increase the response rate and consequently to improve the quality of life for these patients. In locally advanced disease the aim is to reduce the volume of the tumor and to treat micrometastases in order to achieve a better outcome of the subsequent local treatment (i.e., surgery and/or radiotherapy). In these patients the aim is to prolong survival. PATIENT AND METHOD: We have employed 3 different multi-drug regimens with 5-FU+FA combination in 87 consecutive patients with SCCHN. Two regimens (B1, C) have been used for recurrent and/or metastatic disease and only one (B2) for previously untreated patients with locally advanced SCCHN. Regimen B1: cisplatin (P) 30 mg/m2 i.v., 5-fluorouracil (5-FU) 500 mg/m2 i.v., folinic acid racemic form (d, 1-FA) 200 mg/m2 i.v., bleomycin (B) 15 mg im 1st and 2nd day; Regimen C: P 60 mg/m2 1st day, 5-FU 500-750 mg/m2 continuous infusion, FA 50 mg po every 4 hours, B 15 mg im 2nd and 3rd day; Regimen B2 is similar to the B1 but lasts 3 consecutive days (instead of 2) and for every 3 weeks (instead of 4). It consists of 3 cycles before surgical treatment or radiotherapy. RESULTS: There are no statistical differences in the Objective Response (OR) for the regimens B1 (39%) and C (34%). Grade 3-4 toxicity is higher in regimen B1 (50%) than in regimen C (< or = 8%). CONCLUSION: Regimen C is less toxic regimen B1 with no significant difference in the OR. The primary treatment study is still ongoing but the preliminary results are promising: the remission rate is 92% (22/24, 1CR + 21 PR) and the median survival is 18 months (range 3-38+).

High-performance liquid chromatographic analysis of idarubicin and fluorescent metabolites in biological fluids.

A specific, sensitive, and reliable high-performance liquid chromatographic (HPLC) method for the determination of idarubicin (IDA) and its known fluorescent metabolites idarubicinol (IDAol) and 4-demethoxy-daunomycinone (AG1) in biological fluids (human plasma and urine) was developed and tested. Plasma samples were solid-phase-extracted (C18 bonded silica cartridges). Complete separation of unchanged drugs and metabolites was achieved on a Cyanopropyl chromatographic column (25 cm x 4.6 mm inside diameter; particle size, 5 microns) using fluorescence detection (excitation wavelength, 470 nm; emission wavelength, 580 nm). Sensitivity was better than 0.2 ng/ml for all analytes; rates of recovery of unchanged drug and metabolites were better than 84.5% (IDA), 80.3% (IDAol), and 83.9% (AG1). The interassay coefficient of variation was 6.5% for IDA, 5.8% for IDAol, and 9.8% for AG1. Mean intra-assay precision was 4.6% for IDA, 5.9% for IDAol, and 5.0% for AG1 at sample concentrations of above 1 ng/ml and 12.1% for IDA, 10.8% for IDAol, and 14.1% for AG1 at sample concentrations of below 1 ng/ml.

Idarubicin metabolism and pharmacokinetics after intravenous and oral administration in cancer patients: a crossover study.

The pharmacokinetics and metabolism of 4-demethoxydaunorubicin (idarubicin, IDA) were studied in 21 patients with advanced cancer after i.v. (12 mg/m2) and oral (30-35 mg/m2) treatment according to a balanced crossover design. Patients were divided into four groups: subjects who showed normal liver and kidney function (group N), those who presented with normal kidney function and liver metastases (group L), those with kidney dysfunction (creatinine clearance, less than or equal to 60 l/h; group R), and those with both liver and kidney dysfunction (group LR). Five patients showed variations in liver or kidney function after the first treatment and were considered to be nonevaluable for the crossover study but evaluable for the liver/kidney function study; some of them appeared in different groups for the i.v. as opposed to p.o. treatments. After i.v. administration, IDA plasma levels followed a triphasic decay pattern. The main metabolite observed in all patients was the 13C-reduced compound (IDAol), which attained plasma levels 2-12 times higher than those of the parent compound. IDA pharmacokinetics was not dependent on the presence of liver metastases but was related to the integrity of kidney function. Analysis of variance indicated a significant correlation between IDA plasma clearance and creatinine clearance; it was also found that IDA plasma clearance was lower in patients whose creatinine clearance was less than 60 ml/min [group N, 122.8 +/- 44.0 l/h; group L, 104.4 +/- 27.7 l/h (P = 0.58) vs group R, 83.4 +/- 18.3 l/h (P = 0.037)]. The IDAol terminal half-life and mean residence time (MRT) were significantly increased in patients with impaired kidney function [MRT: group N, 63.6 +/- 10.8 h; group L, 69.9 +/- 10.2 h (P = 0.27) vs group R, 83.2 +/- 10.9 h (P = 0.025) and t1/2 gamma: group N, 41.3 +/- 10.1 h; group L, 47.0 +/- 7.4 h (P = 0.31) vs group R, 55.8 +/- 8.2 h (P = 0.025)]. After oral treatment, drug absorption occurred during in the first 2-4 h after IDA administration; a biphasic decay pattern was observed thereafter. The main metabolite observed in all patients was again IDAol. The AUC of IDAol was greater after oral administration than after i.v. treatment in proportion to the AUC of IDA (i.v.: AUC-IDAol/AUC-IDA, 2.4-18.9; p.o.: AUC-IDAol/AUC-IDA, 4.1-21.4). Following oral dosing, a substantial amount of 4-demethoxydaunomycinone (AG1) was found in 11/21 patients.(ABSTRACT TRUNCATED AT 400 WORDS)

Chemotherapy with cisplatin, epirubicin, methotrexate in the treatment of locally advanced or metastatic transitional cell cancer of the bladder (TCC).

Forty patients with advanced transitional cell cancer (TCC) of the bladder were treated with cisplatin, epirubicin, methotrexate (PEM, every 3-4 weeks). If creatinine clearance was reduced to 40 ml/min, the usual full doses of cisplatin and methotrexate, 50 mg/m2, were proportionally reduced. 23 patients had full-dose (FD) therapy, 17 had reduced dose (RD) (40-20 mg/m2). Two patients achieved complete response and 17 partial response. The overall response rate was 19/40 (47.5%), 11/23 (48%) for FD and 8/17 (47%) for RD (p = 1.000). 17/40 pts (42.5%) had no-change and 4/40 (10%) had disease progression. The median duration of CR and PR was 32 weeks, range 4-82 (22 weeks, range 12-52 for FD; 32 weeks, range 4-82 for RD, cisplatin p = .7362). The main side effect was vomiting (35/40 pts, 87.5%, 20/23 = 87% for FD, 15/17 = 90% for RD, p = 1.000). Leukopenia was observed in 12 patients (30%, nadir 3,240 range 900-3,800, 6/23 = 26% for FD, 6/17 = 35% for RD, p = .7285), alopecia in 18 patients (45%, 15/23 = 65% for FD, 3/17 = 18% for RD, p = .004). The results of this study show that a dose escalation to 50 mg/m2 for cisplatin, epirubicin and methotrexate in the PEM regimen results in an increase in overall response (OR) (19/40 = 47.5%) with respect to a historical control using the same drugs at doses of 40 mg/m2 (12/35 = 34%). In patients with normal renal function the escalated dose was tolerated without a corresponding increase in toxicity.(ABSTRACT TRUNCATED AT 250 WORDS)

The antiemetic efficacy and the cost-benefit ratio of ondansetron calculated with a new approach to health technology assessment (real cost-benefit index).

In a phase II study including 80 patients treated with highly emetic drugs such as cisplatin, carboplatin or cyclophosphamide > 600 mg/day) we confirmed the potential of ondansetron to prevent cancer chemotherapy- related acute nausea and vomiting. With a total dose of 19.0-37.3 mg ondansetron we achieved 82%-100% acute (0-24 hours) vomiting free patients. Using ondansetron for the prevention of acute nausea and vomiting increases the total chemotherapy costs by 6%. The real cost-benefit ratio for the treatment of acute nausea and vomiting shows better values for ondansetron than for all other recommended regimens.

A phase II study of high-dose epirubicin plus cisplatinum in advanced non-small-cell lung cancer (NSCLC).

Thirty-seven patients with unresectable NSCLC received epirubicin (EPI) as i.v. bolus at the dose of 120 mg/sm+cisplatinum (CP) at the dose of 60 mg/sm every 28 days up to the maximum cumulative dose of 840 mg/sm of EPI. Of 35 evaluable patients, 19 (54%) (95% confidence limits: 37%-71%) achieved PR for a median duration of 10 months (range: 2-21). The majority of responsive patients experienced improvement in performance status, related-disease symptoms and body weight. Grades 3-4 leukopenia occurred in 42% of the patients. In five patients there was a > 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 9 months (range 2-26). This study shows that inclusion of HD-EPI in a combination regimen contributes to obtaining a high remission rate in advanced NSCLC.

The Bologna Eubiosia Project: hospital-at-home care for advanced cancer patients.

Since 1985 the Associazione Nazionale per lo Studio e la Cura dei Tumori Solidi (ANT), an Italian nonprofit anticancer organization, has provided a hospital-at-home care program for advanced and very advanced cancer patients. This program is part of the Eubiosia Project which also includes a number of complementary services. Teams of doctors, nurses, and psychologists work round-the-clock in the region and on hospital wards, assisted by diagnostic and therapeutic facilities applicable at home and by a round-the-clock on-call service seven days a week. The patients who were treated between December 1985 and December 1991 numbered 5603, of whom 2130 received treatment in 1991 alone, with 702 patients on line at the end of the period. The mean duration of home care for the first 2803 deceased patients was 62 days, and the percentage of deaths at home was 70%. We analyzed control of the main symptoms and the residual survival in three groups of patients--stomach, lung, and breast cancer sufferers--and found that acceptable pain control was achieved in 95% of cases. From the retrospective analysis of our data it can be seen that the eligibility criteria for entry to home care should not only depend upon performance status and the presence of symptoms, but should also take into account the factors that are inherent to the natural history of any kind of tumor as well as the social, domestic, and psychological characteristics of the patients.

Activity of high-dose epirubicin in advanced non-small cell lung cancer.

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.

5-Fluorouracil, epirubicin and cyclophosphamide (FEC combination) in advanced breast cancer.

Thirty patients with advanced breast cancer, not pretreated with chemotherapy for advanced disease, received a polychemotherapy regimen containing 5-fluorouracil (500 mg/m2 iv), epirubicin (50 mg/m2 iv) and cyclophosphamide (500 mg/m2 iv) every four weeks. All patients were evaluable for response and for toxicity. No complete remissions were observed, while 13 patients (43.5%) achieved a partial remission for a median duration of 46 weeks. The main side-effects were alopecia (grade 2-3 in 57%), leukopenia (grade 3-4 in 33%) and nausea/vomiting (grade 3-4 in 27%). In three cases we observed laboratory signs of cardiotoxicity without clinical symptoms.

5-fluorouracil + folinic acid with cisplatinum and bleomycin in the treatment of advanced head and neck squamous cell carcinoma.

Thirty-six patients with advanced squamous cell carcinoma of the head and neck (SCCHN) were treated with a regimen including cisplatinum (CP) 30 mg/m2 i.v., 5-fluorouracil (5-FU) 500 mg/m2 i.v. bolus, folinic acid (FA) 200 mg/m2 i.v. in a continuous one-hour infusion, and bleomycin (B) 15 mg i.m. on the first and second days and repeated every 28 days. Thirty-three patients (25 with recurrent disease and 8 untreated) are evaluable for objective response. Of these, 4 (12%) achieved CR and 15 (45%) PR. All of the untreated patients responded. The mean duration of response in the patients with recurrent or metastatic disease was 5.5 months (range 2-10+). Remission of symptoms, such as pain and dysphagia, was obtained in 58% and in 44%, respectively. Subjective remission occurred almost exclusively in objectively responsive patients. The major side effects were leukopenia (55%) and nausea/vomiting (58%). This regimen is active in the treatment of advanced SCCHN. The quality of life may be improved in responsive patients.
