We have used a relatively new trial methodology, the group sequential design, to prospectively evaluate two dose levels of bolus/infusional 5-fluorouracil (5-FU) and folinic acid in 192 consecutive-patients with advanced colorectal carcinoma. On day 1, all patients received 200 mg m(-2) of folinic acid infusion over 2 h. Cohort A (n = 102 patients) received 500 mg m(-2) 5-FU by i.v. 15-min infusion followed by an infusion of 500 mg m(-2) 5-FU over 22 h. Treatment was repeated on day 2 and further cycles given 2-weekly. After sequential analysis excluded a response rate of over 40%, cohort B (n = 90 patients) received an increased dose of 600 mg m(-2) 5-FU bolus and infusion. Patients had received no prior 5-FU therapy and the two cohorts had similar demographic features. In 179 evaluable patients, the overall response rate was 18% (95% CI 12-24%) with CR of 6% and PR of 12%, with no difference between the two cohorts. Overall median survival was 34 weeks (95% CI 30-39) with no significant difference between cohorts (median survival 32 and 37 weeks in cohort A and B respectively; P = 0.27). On multivariate analysis, poor performance status, elevated initial WBC and alkaline phosphatase and low serum albumin were associated with reduced survival (P < 0.05), and initial raised WBC showed an association with reduced likelihood of response (P = 0.002). Overall toxicity was low with CTC grade 3 mucositis, diarrhoea, nausea or vomiting in < or = 6% of patients and no treatment-related deaths. Significant (grade 3 or above) leucopenia was more common in cohort B than in cohort A (9% and 1% respectively); there were more dose reductions, and the median administered dose intensity was lower in cohort B than in cohort A (89% and 97% respectively; P = 0.006). In this group of relatively unselected patients, we have confirmed a relatively low objective response rate and median survival of 7.8 months with this regimen. There was no significant difference in outcome between the two dose levels but the higher dose of 5-FU was associated with more dose reductions and greater toxicity.

This prospective multicenter trial was performed to determine the response rate, toxicity and applicability of continuous 24 h hepatic arterial infusion of high-dose 5-FU and folinic acid. An improved response rate (60.5% in non-pretreated patients) was however associated with many systemic side-effects (340/509), mainly nausea and diarrhea. Therefore this treatment should be applied only in selected patients in specialized centers.

Twenty-four consecutive patients with metastatic breast carcinoma (MBC) refractory to first line chemotherapy were treated with high-dose folinic acid (FA) 100 mg/m2 diluted in 250 cc of normal saline as 2 hour infusion followed by 5-fluorouracil (5FU) 400 mg/m2 bolus then 5FU 600 mg/m2 as continuous infusion for 22 hours. This therapy was repeated for 2 consecutive days. Chemotherapy was repeated every 15 days. All enrolled patients were evaluable for objective response. A complete response was achieved in 1 patient (4%) and a partial response in 6 cases (25%) for an overall response rate of 29% (confidence limits 18%-39%). The median duration of objective responses was 8.4+ months (range 3.0+/12.8). Six patients showed no change (25%) with a median duration of 4.0 months 11 patients progressed (46%). A subjective improvement in tumor-related symptoms was reported by all responding patients and in 3 patients with no change. Most patients (7/10) with symptomatic bone lesions had a subjective improvement with reduction in analgesic drugs consumption. Objective responses were observed at all sites of disease. In fact, responses were seen in the skin liver lung bore and rodal metastases. The median overall survival was 13.0+ months (range 4.0/16.2+). Over a total of 160 cycles (a mean of 6.6 cycles/patient) grade 1-2 leukopenia was seen in 9 patients (37%) grade 1 thrombocytopenia in 4 patients (17%) and grade 1 anemia in only 2 cases (8%). Grade 3-4 leukopenia or thrombocytopenia were not seen. Phlebitis at the injection vein occurred in 3/10 patients (30%) which refused to implant a central line. In patients with a central line or a port-a-cath no cases of vascular, toxicity were seen. Gastrointestinal toxicity was very mild with 9 patients (37%) suffering from grade 1-2 nausea/vomiting 6 patients (25%) complaining of grade 1-2 diarrhea and 6 patients with grade 1-2 stomatitis. Hand-foot syndrome was observed in only 1 patient. No cases of grade 3-4 gastrointestinal toxicities have been, observed. No cases of cardiotoxicity and/or neurotoxicity were recorded. The combination of high-dose FA and 5FU given as 48 hour continuous venous infusion every 2 weeks is active, at least in terms of objective response rate and tumor-related symptoms palliation against anthracycline-refractory MBC. These results compare favorably with bolus administration of FA and 5FU or other salvage regimens.

The aim of this study was to develop a phase II study gauging the contribution of a daily low-dose of carboplatin combined with 5-fluorouracil (5-FU) and folinic acid (FOL) in a chronotherapy schedule for advanced colorectal cancer patients. 60 patients with metastatic colorectal cancer were included in a phase II trial in which 50% of patients had received prior chemotherapy of up to three regimens. Treatment consisted of a combination of 5-FU (700 mg/m(2)/day) and FOL (300 mg/m(2)/day) infused from 10.00 pm to 10. 00 am peaking at 4.00 am with carboplatin infused from 10.00 am to 10.00 pm at 40 mg/m(2)/day with a peak at 4.00 pm. 4-day courses were repeated every 2 weeks in an ambulatory setting with a programmable pump. Patients experienced excellent tolerance (grades III-IV%): diarrhoea, 8.1; nausea/vomiting, 4.8; mucositis, 3.2; skin or neurological 1.7; granulocytes 29.0; platelets and haemoglobin (Hb) 9.7. Major tumour responses were observed in 47% of cases, 4 complete response (CR), 24 partial response (PR); 3 CR and 6 PR (69%) were recorded in 13 previously untreated patients; 11 (18%) underwent subsequent surgical resection of residual metastases. Median survival was 14.6 months with 22% patients surviving over 2 years (35% survival for responders versus 0 for non-responders). In conclusion, this chronotherapy determined administration of 5-FU/FOL and carboplatin yielded an excellent therapeutic index for the combination and warrants further evaluation in the first-line treatment of metastatic colorectal cancer.

The efficacy of oxaliplatin combined with high-dose 5-fluorouracil (5-FU) and folinic acid (FA) as an outpatient salvage treatment for patients with metastasized colorectal cancer was retrospectively analyzed in one center. Tumor progression had occurred for the majority of patients during two regimens (n = 11) otherwise during one (n = 1) regimen of prior 5-FU-based chemotherapy, which had been applied in a standardized sequential fashion. As third-line therapy oxaliplatin was infused intravenously over 2 h at a dose of 60 mg/m2 prior to a 2-h infusion of FA (500 mg/m2). 5-FU (2,600 mg/m2) was subsequently given over 24 h. A favorable response was observed in 9/12 (75%) of the heavily pretreated patients, including partial remissions in 3/12, minor responses in 2/12 and stable disease in 4/12 patients. The median progression free time was 23 weeks (interquartile range i. r. 0-28) for all patients, the median survival time from start of third-line therapy 55 weeks (i. r. 40-86). The median survival time from the beginning of first-line palliative chemotherapy was 34 months (i. r. 25-45 months). The highest toxicity was WHO grade III and was observed in six patients: Nausea (2), diarrhea (3), vomiting (2) and peripheral neuropathy (1). The quality of life was not adversely affected by the oxaliplatin/5-FU/FA-regimen as assessed by the EORTC QLQ-C30 questionnaire. Thus, the results show the efficiency and low toxicity of oxaliplatin/high-dose 5-FU/FA as palliative third-line therapy of patients with metastasized colorectal cancer and emphasize that sequential palliative chemotherapy may lead to extended survival of these patients.

To evaluate the toxicity and efficacy of combination chemotherapy with paclitaxel, cisplatin and 24 h continuous infusion of 5-FU/folinic acid in patients (pts) with unresectable, locally advanced or metastatic gastric adenocarcinoma. Forty-five chemotherapy-naive pts (28 male and 17 female) with a median age of 60 years (range 35-74) were enrolled. 5-FU 2 g/m2 was given weekly over 24 h i.v. preceded by folinic acid 500 mg/m2 as a 2 h infusion. Paclitaxel 175 mg/m2 was administered as a 3 h-infusion on days 1 and 22 and cisplatin 50 mg/m2 as 1 h infusion on days 8 and 29. Six weeks of therapy (days 1, 8, 15, 22, 29, 36) followed by 2 weeks rest were considered one cycle. A median of 3 cycles (range 1-4) were administered to 45 pts assessable for response, survival and toxicity. Five pts (11%) obtained a CR and 18 pts (40%) a PR (ORR 51%; 95% CI: 35.8-66.3%). Responses were achieved in the liver, lymph nodes, lungs and at the site of the primary tumour. Nine pts (20%) had stable disease. Thirteen pts (29%) were considered to have failed treatment, 8 pts (18%) due to progressive disease and 5 pts (11%) who did not receive one complete cycle of therapy due to acute non-haematologic toxicity. The median progression-free and overall survival times were 9 months (range 1-36+) and 14 months (range 2-36+), respectively. Neutropenia WHO III(o)/IV(o) occurred in 7 pts (15%) with only 1 pt having grade IV. Additional non-haematologic WHO III(o)/IV(o) toxicities included nausea/vomiting in 5 (11%), alopecia in 22 (49%), and diarrhoea in 1 patient each (2%). Dose reductions or treatment delays were necessary in 8 pts (17%), mainly due to neutropenia. All pts were treated on an outpatient basis. The combination of paclitaxel, cisplatin and continuously infused 5-FU/folinic acid appears to be a highly active regimen for the treatment of pts with advanced gastric cancer. While the overall acceptable toxicity allows its use in the palliative setting, it may also be an attractive option to be tested for neoadjuvant or adjuvant treatment.

In this adjuvant three-arm multicenter trial, we studied whether modulating the standard 5-fluorouracil (5-FU) treatment with either folinic acid (FA) or interferon-alpha-2a (IFN-alpha) was superior to the recommended standard of adjuvant treatment in R0 resected colon cancer, 5-FU plus levamisole (LEV) for 12 months, in terms of toxicity and outcome. From July 1992 to October 1999, a total of 813 patients with resected colon cancer in stage II (T4N0M0; n = 63) or stage III (TxN1-3M0; n = 750) were randomized into three treatment groups and stratified according to N stage and participating centers (64 hospitals). The patients received a postoperative loading dose of 5-FU (450 mg/m2 on days 1 to 5 [arms A and C]) or 5-FU (450 mg/m2) plus FA (Rescuvolin, Medac, Hamburg, Germany, 200 mg/m2 on days 1 to 5 [arm B]). After completion of the first chemotherapy cycle, LEV was administered orally at a dosage of 150 mg per day on days 1 to 3, once every 2 weeks. After a 4-week chemotherapy-free interval, the treatment was continued weekly for 52 weeks. Treatment in one arm A ("standard") (n = 279) consisted of 5-FU intravenously (450 mg/m2 on day 1, once a week) plus LEV. 5-FU plus LEV was modulated in arm B (n = 283) with FA (200 mg/m2 on day 1, once a week) and in arm C (n = 251) with IFN-alpha at 6 million units three times a week repeated weekly. Treatment dosages were adjusted if toxic events above WHO grade 2 occurred. Patients were closely followed to determine recurrence and survival; the latter was calculated according to Kaplan-Meier analysis. Toxic events above WHO grade 2, mainly leukopenia, diarrhea, and nausea, occurred in 113 (14%) of 649 patients who had completed treatment in arms A (8.4%), B (13.5%), and C (31.7%). Discontinuance rates were as follows: 28% for all patients, 29% in arm A, 21% in arm B, and 34% in arm C. Overall relapse rates were 27% for all patients, 30% in arm A, 24% in arm B, and 28% in arm C. Relapses were local (8%), distant (78%), or combined (12%). Four-year overall survival rates in arms A, B, and C were 66.1%, 77.5%, and 66.2%, respectively. The 4-year survival rate in arm B was significantly higher compared to arm A (P <0.02, log-rank test) with arm A being equal to arm C. Adjuvant therapy with 5-FU plus FA plus LEV for 12 months is superior to the recommended standard (5-FU + LEV for 12 months). IFN-alpha modulation of 5-FU (plus LEV) adds to the toxicity with no therapeutic benefit.

BACKGROUND: Gastric carcinoma still is a worldwide major cause of cancer death. Although various chemotherapy schedules yielded high response rates, median survival rarely exceeds 8-10 months. Many regimens are inevitably associated with significant toxicity which jeopardizes their value as palliative treatment, especially in patients with reduced performances status. Therefore, we initiated a phase II study for the treatment of advanced gastric carcinoma using a bolus regimen with mitomycin C (MMC), 5-fluorouracil (5-FU) and folinic acid (FA), allowing the enrollment of elderly patients or those with reduced performance status (WHO grade 2). PATIENTS AND METHODS: Between 1996 and 1998 we recruited a total of 58 patients with advanced gastric cancer to receive bolus MMC 3 mg/m(2), 5-FU 450 mg/m(2), and FA 100 mg/m(2) on days 1-3. Treatment was repeated on day 22. 53 patients met the inclusion criteria: male n = 36, female n =17; median age 65 (range 26-81); mean WHO status 1 (range 0-2). RESULTS: Out of 53 patients 50 were evaluable for response, all 58 patients who received therapy were evaluable for toxicity. Eleven patients (22%) achieved partial remission (95% CI: 11.5 -36.0%), 24 (48%) no change and 15 (30%) were progressive. Median overall survival was 11.5 months, the median time to progression 6.0 months. Out of 290 treatment cycles the worst toxicities observed (WHO 2/3/4) were as follows: anemia 13/3/1, leukopenia 19/1/1, thrombopenia 11/3/0, nausea/emesis 11/2/0, infections 2/1/0, diarrhea 14/2/0, and stomatitis 6/1/1. One patient developed hemolytic-uremic syndrome. CONCLUSIONS: The tumor control rate (PR + NC) of 70% was comparable to established chemotherapy regimens, while median overall survival was promising. Toxicity was mild, allowing the treatment especially for elderly patients and on outpatient basis. Copyright 2000 S. Karger GmbH, Freiburg

The objective of this study was to determine the toxicity and the efficacy of the combination of cisplatin, etoposide, 5-fluorouracil (5-FU) and folinic acid in the treatment of patients with advanced squamous cell carcinoma of the esophagus. Patients received cisplatin 80 mg/m(2) i.v. on day 1, etoposide 125 mg/m(2) i.v. on day 1 and etoposide 200 mg/m(2) p.o. on days 3 and 5, 5-FU 375 mg/m(2)/day continuously i.v. combined with folinic acid 30 mg p.o. 6 times per day on days 1--4. Courses were repeated every 4 weeks until progression or up to a maximum of 6 courses. Patients were evaluated for response after every two courses. Sixty-nine patients received a total of 291 courses (median 4, range 1--6). The hematological toxicity consisted of leukocytopenia grade 3 or 4 in 17 and 16% of patients, respectively. Leukocytopenic fever was seen in 19% of patients. Thrombocytopenia grade 3 or 4 was seen in 13 and 7% of patients, respectively. Non-hematological toxicity consisted of nausea/vomiting grade 3 in 32%, diarrhea grade 3 in 6% and mucositis grade 3 or 4 in 23% of patients. The overall response rate was 34% (complete response 4%, partial response 30%) and the median time to progression was 7 months in 13 patients who received no additional treatment. The median survival for all patients was 9.5 months with a 1-year survival rate of 36%. Ten patients with initially locally unresectable disease (N=2) or celiac or supraclavicular lymph node metastases (N=8) who received additional treatment (esophageal resection in seven patients and radiotherapy in three patients) after they had responded to chemotherapy had a 3-year survival of 50%. We conclude that the combination cisplatin and etoposide combined with 5-FU and folinic acid is a safe and active regimen for patients with advanced squamous cell carcinoma of the esophagus. Mucositis is the most prevalent toxicity.

Tegafur is a prodrug of the antineoplastic agent fluorouracil, and is administered in a 1:4 molar ratio with the fluorouracil modulator uracil. Oral tegafur/uracil 300 mg/m(2)/day plus calcium folinate 75 or 90 mg/day for 28 days every 35 days was as effective as intravenous (IV) fluorouracil 425 mg/m(2)/day plus folinic acid 20 mg/m(2)/day for 5 days every 28 or 35 days in the treatment of patients with metastatic colorectal cancer in two large, randomised, nonblind, multicentre trials (n = 816 and 380). Median survival time among patients treated with tegafur/ uracil or fluorouracil was approximately 12 months in both trials. Results from both trials also demonstrated no significant between-group differences in overall response rates among patients treated with oral tegafur/uracil (12 and 11%) or IV fluorouracil (15 and 9%). In elderly patients (aged > or = 70 years) with metastatic colorectal cancer, results from small noncomparative studies showed that treatment with oral tegafur/uracil afforded overall response rates of 12.5 to 29% and was well tolerated. During preoperative treatment with oral tegafur/uracil plus calcium folinate as an adjunct to radiotherapy in patients with stage II or III rectal cancer, the maximum tolerated dosage of tegafur/uracil was 350 mg/m(2)/day (administered 5 days per week for 5 weeks). Among the 15 patients who were followed for 5 to 8 months, three had a complete response to treatment. Treatment with tegafur/uracil was also given postoperatively. The most common adverse events associated with oral tegafur/uracil were anaemia, nausea/vomiting, diarrhoea, thrombocytopenia, mucositis, neutropenia, asthenia, anorexia and abdominal pain. Oral tegafur/uracil was associated with a significantly more favourable tolerability profile than IV fluorouracil in the two large randomised trials. In particular, stomatitis and most adverse haematological events were less frequent.
