Thirty patients with a diagnosis of metastatic adenocarcinoma of the lung were entered on a trial to evaluate the antitumor efficacy of 5-fluorouracil 370 mg/m2 daily for 5 days every four weeks in combination with folinic acid 200 mg/m2, 60 mm prior to 5FU. All patients had a good performance status, bidimensionally measurable disease, and weight loss ≤5% of preillness weight. Of the 29 evaluable patients, only two (7%) had partial responses (95% confidence limits 1-24%). Eleven (38%) had stable disease and 16 (55%) progressed. The two responding patients survived 12 and 60+ weeks. The median survival of all evaluable patients was 25 weeks (range 7-60+) and that of the stable patients was 26 weeks. The principal toxicities observed were diarrhea and stomatitis. Myelosuppression was rarely dose limiting. In contrast to the results of treatment with 5FU and folinic acid in metastatic colorectal cancer and breast cancer, the results of treatment with this combination of agents have been much less encouraging in adenocarcinoma of the lung. 相似文献

This dose escalation study was designed to determine the maximum tolerated dose (MTD) and recommended doses (RDs) of 5-fluorouracil (5FU), folinic acid and oxaliplatin (FOLFOX) with concomitant radiotherapy in inoperable/metastatic oesophageal squamous cell carcinoma or adenocarcinoma. Patients received three courses of LV5FU2 regimen (folinic acid 200 mg m(-2), bolus 5FU 300-400 mg/m(2), continuous infusion 5FU 400-600 mg m(-2) on days 1 and 2) and escalating doses of oxaliplatin 50 to 100 mg m(-2) on day 1 (FOLFOX). This regimen was repeated every 2 weeks, concomitant to a 50-gray radiotherapy per 5 weeks. Three more cycles were delivered after completion of radiation therapy. Three to six patients were allocated to each of the five dose levels until MTD was reached. Thirty-three patients were enroled and 21 had metastatic disease. Maximum tolerated dose was oxaliplatin 100 mg m(-2), and continuous infusion 5FU was 600 mg m(-2) day(-) (level 5). The most common toxicities were neutropenia, dysphagia and oesophagitis. The RDs were those of FOLFOX-4 regimen (oxaliplatin 85 mg m(-2) and full doses of LV5FU2). The overall response was 48.5%, including 12% complete response. Response rate on primary tumour was 62.9%. This FOLFOX-4 regimen was reasonably well tolerated and effective in inoperable/metastatic oesophageal carcinoma and warrants additional investigation. 相似文献

One hundred eighty-one patients with measurable recurrent or metastatic colorectal cancer, who had not received prior chemotherapy, were randomized in a prospective controlled trial to receive 5-fluorouracil (5FU), 13.5 mg/kg, for five days (arm A) or high-dose folinic acid [Cyanamid-Lederle, Italy] (FA), 200 mg/m2, for five days and 5FU, 400 mg/m2 for five days (arm B). The treatments were repeated every four weeks. One hundred fifty-five patients were evaluable for response. The two arms were balanced for all potential prognostic factors studied. The response rate (CR+PR) was 18% in the 5FU arm and 16% in the 5FU plus FA arm. Median duration of response was 56 weeks for 5FU alone and 42 weeks for the combination (p = 0.48). Median time to failure (TTF) was 20 weeks for arm A and 21 for arm B (p = 0.62). Median survival was 62 weeks on the 5FU arm and 53 weeks on the FA plus 5FU arm (p = 0.14). Dose intensity (DI) delivered was the same in both arms. Diarrhea and mucositis were the most frequent adverse reactions in arm B; 20% of the patients in arm A and 38% of those in arm B experienced diarrhea (p = 0.008). Mucositis occurred in 34% of patients in arm A and 42% in arm B (p = 0.04). In general nausea and vomiting were moderate. Hematological toxicity was more severe in patients treated with 5FU alone: 31% in arm A and 14% in arm B developed leukopenia (p = 0.015). In the combination arm one patient died due to gastrointestinal and hematological toxicity after the seventh cycle. This study indicates that, in advanced colorectal cancer, the combination of high-dose FA and 5FU is not superior to 5FU alone when utilized at standard high-dose intensity. 相似文献

Thirty evaluable patients were treated with methotrexate (MTX) 200 mg/m2, i.v. infusion over 60 minutes, 24 hours prior to the administration of 5-fluorouracil 600 mg/m2, and folinic acid 200 mg/m2, i.v. infusion over 60 minutes, every 2 weeks. A partial or complete response was achieved in 12 patients (40%), and disease stable in 10 patients (33%). Median actuarial survival was 18 months. Side effects, which were within acceptable limits, included 11 cases of stomatitis (5 Grade 3), 3 cases of leukopenia (Grade 2) and 12 cases of mild nausea and vomiting. We conclude that the present combination is active in metastatic colorectal cancer with mild toxicity. These results are being confirmed and a randomized trial is being carried out to prove that this combination holds therapeutic advantage. 相似文献

Only a few drugs are active in the treatment of well-differentiated endocrine carcinomas (WDEC). We evaluated the combination of the so-called 'de Gramont schedule' and irinotecan in these tumors in a phase II study. METHODS: 20 patients were enrolled in the study. The combination regimen included irinotecan, 180 mg/m(2) on day 1, followed by 200 mg/m(2) folinic acid in a 2-hour infusion, an intravenous 10-min bolus of 400 mg/m(2) 5-fluorouracil (5FU) and finally 600 mg/m(2) 5FU in a 22-hour infusion. Folinic acid and 5FU were repeated on day 2. Clinical, biological and morphological parameters were assessed by CT every 8 weeks. The site of the primary tumor was the pancreas in 10 cases, the lung in 3 cases and other sites in 7 cases. Sixteen patients had previously received chemotherapy, and 6 of them had had two lines of treatment. Six patients had previously been treated with chemoembolization. RESULTS: The median number of cycles administered was 8. Grade 3-4 neutropenia was observed in 8 patients, and 1 patient experienced febrile neutropenia. There was no toxicity-related death. No complete symptomatic response was observed in 7 evaluable patients; 4 patients had an objective biological response. One patient achieved a morphological objective response, stabilization was observed in 15, but progression occurred in 3 patients. Median survival was 15 months. CONCLUSION: The above-mentioned combination of LV5FU2 + irinotecan does not yield major activity in heavily pretreated unresectable metastatic gastroenteropancreatic WDEC, and significant toxicity was observed. 相似文献

Twenty-five patients with advanced measurable gastric cancer were treated with high-dose folinic acid (200 mg/m2), 5-fluorouracil bolus (400 mg/m2) and continuous infusion (600 mg/m2) for two consecutive days every two weeks. Fourteen patients over 65 yr old and/or with a poor general status received first-line treatment, and eleven younger patients second-line. The response rate was 43.5% in 23 evaluable patients. There were 2 complete responses (8.7%) and 8 partial responses (34.8%). Median survival was 6 months in first-line and 8 months, calculated from start of folinic acid-5FU, in second-line. Toxicity was mild without WHO Grade greater than 2 events. This combination is effective for advanced gastric cancer in poor-prognosis patients and requires further studies. 相似文献

Summary Standard combination chemotherapy for metastatic breast cancer produces response rates between 30–60% with limited impact on survival. We undertook a phase II trial to determine the activity of 5 fluorouracil (5FU) and folinic acid (FA) in patients with measurable metastatic or recurrent breast cancer who had received no prior chemotherapy. Patients meeting the eligibility criteria received 5FU 370 mg/m2/day and FA 200 mg/m2/day for 5 days repeated every 28 days, toxicity allowing. Response defined by standard criteria was assessed every 8 weeks and toxicity according to WHO criteria was determined on every course. Thirty-three patients were entered on trial. Thirty-two patients were evaluable for response and 33 for toxicity. The dose limiting toxicity was stomatitis with 7/32, 19/32, and 5/32 patients experiencing grade 1, 2, and 3 toxicity. Grades 1 and 2 diarrhea occurred in 17/32 and 11/32 patients respectively. Myelosuppression was not significant. Two complete and 11 partial responses were observed. The overall response rate was 41% (95% CI, 24–58%). Responses were seen in soft tissue and visceral sites. Patients who had received adjuvant chemotherapy more than 6 months prior to receiving 5FU and FA responded also. Six of 29 patients receiving standard combination chemotherapy as second line treatment responded subsequently. We concluded: 1) 5FU and FA is an active combination in the treatment of breast cancer warranting further evaluation in combination with other drugs; 2) the dose-limiting toxicity of stomatitis is tolerable; 3) patients receiving 5FU and FA as first line therapy can respond to conventional combination chemotherapy as second line treatment. 相似文献

25 patients with metastatic colorectal carcinoma previously treated with 5-fluorouracil and folinic acid for advanced disease, were treated with mitomycin C 8 mg/m(2) i.v. bolus on day 1, adriamycin 40 mg/m(2) i.v. bolus on day 1, and lonidamine 150 mg per os t.i.d. starting one day before chemotherapy and stopping 2 days after the end of chemotherapy. Treatment was repeated every 4 weeks. All patients had previous surgery and systemic chemotherapy with 5-fluorouracil and folinic acid given as first line chemotherapy for metastatic tumor. Sites of disease included liver, lung, nodes, abdomen, and bone. All enrolled patients were evaluable for objective response. Only one patient, affected by rectal carcinoma, showed a partial response (4%) which lasted 5.8+ months. No complete response was seen. Stable disease was recorded in 4 cases (16%) with a mean duration of 4.6+ months. All remaining patients had progressive disease. Median overall survival was 8.7+ months. Toxicity was significant. Grade 3 thrombocytopenia was seen in 8 cases (32%), and grade 3 leukopenia in 5 cases (20%). Grade 3 vomiting was observed in 9 patients (36%). The combination of mitomycin C, adriamycin and lonidamine is not effective in the treatment of metastatic colorectal adenocarcinoma resistant to 5-fluorouracil-based chemotherapy. These data suggest that lonidamine is not able to potentiate antineoplastic activity of chemotherapeutic drugs in humans and its use in colorectal cancer should be avoided since it has no or little impact on response rate and survival. 相似文献

BACKGROUND AND AIM: In vitro, methotrexate (MTX) is the best modulator for bolus 5-fluorouracil (5FU), whereas folinic acid (FA) is the best for continuous infusion. We evaluated the effect of 5FU modulated by both MTX (bolus administration) and FA (continuous infusion) as second-line treatment of patients with metastatic colorectal cancer. PATIENTS AND METHODS: Entry criteria were: at least one 5FU-based chemotherapy regimen as first-line treatment for metastatic disease, or progression within twelve months after 5FU-containing adjuvant therapy. Treatment schedule: MTX 200 mg/m2 i.v. days 1 and 15; 5FU 600 mg/m2 i.v. bolus, days 2 and 16; 5FU 200 mg/m2 i.v. continuous infusion for 21 days, starting on day 29; FA 20 mg/m2 i.v. bolus weekly during the three weeks of 5FU infusion. Cycles were repeated every 56 days. The primary end-point was tumour control rate, including partial responses and stabilizations. RESULTS: 34/35 patients enrolled were evaluable for response. Five (14.7%) had a partial response, 13 (38.2%) disease stabilization, and 16 (47.1%) progressed; tumour control rate was 52.9%. Median TTP was 5.8 months (95% CI 4.03-7.83); 29 patients had died. Median OAS was 15.9 months (95% CI 8.8-21.9). Toxicity was mild. CONCLUSIONS: The regimen constituted by 5FU modulated by MTX (bolus administration) and FA (continuous infusion) is active as second-line treatment of metastatic colorectal cancer. 相似文献

AIMS AND BACKGROUND: Combined 5-fluorouracil (5FU) and folinic acid (FA) is the first-line treatment of metastatic colorectal cancer. The aims of this study were to individualize the dose of 5FU in a weekly schedule in which the maximum tolerated dose of 5FU is administered to each patient, and to evaluate the impact of increasing 5FU doses on response and survival. METHODS: Thirty-two patients (30 evaluable for response) with metastatic colorectal cancer were treated with weekly intravenous doses of FA 150 mg/m2 and a fast infusion of 5FU, at an initial dose of 600 mg/m2 which was increased by 60 mg/m2 every week until the appearance of a side effect, in order to determine the maximum tolerated dose for the patient. RESULTS: We obtained 11 objective responses (36.7%, median survival 22 months) and 15 disease stabilizations (50%, median survival 15 months); there were four cases of progressive disease (13.3%, median survival 4 months). The overall survival was 15 months. Twenty-eight patients (87.5%) tolerated 5FU doses of 720 mg/m2 or more. CONCLUSIONS: Weekly 5FU with high-dose FA modulation can be individualized by dose escalation. A 5FU dose of 720 mg/m2 per week seems to be critical, as higher doses are no more effective and lead to severe side effects. This schedule gives good results in terms of response, even though the complete response rate remains low. 相似文献

Background: Bladder cancer is a chemosensitive tumour, however,there is no effective therapy for patients with metastatic diseasewho failed to respond or relapsed after prior treatment withcisplatin-based chemotherapy. Single agent 5-fluorouracil hasmodest activity in bladder cancer. The combination of 5-fluorouracilwith folinic acid results in stabilization of the ternary complexof 5-fluorodeoxyuridine monophosphate-thymidylate synthetase-5,10methylene tetrahydrofolate leading to increased DNA inhibitionand increased cytotoxicity of 5-fluorouracil Patients and methods: Fourteen evaluable patients with metastaticbladder cancer were treated with 5-fluorouracil at 300 mg/m2and folinic acid at 200 mg/m2 daily for five days Results: There were no complete or partial responses. One patienthad a minor response and three patients had stable disease.Diarrhea and mucositis occurred in 25% of patients.

PURPOSE: To evaluate the toxicity and activity of infusional fluorouracil (FU), folinic acid (FA), and oxaliplatin, administered every 2 weeks in patients with metastatic gastric cancer. PATIENTS AND METHODS: Forty-one previously untreated patients with measurable adenocarcinoma of the stomach were eligible for the study. Patients received FU 2.6 g/m(2) (24-hour continuous infusion), FA 500 mg/m(2) (2-hour intravenous infusion), and oxaliplatin 85 mg/m(2) (2-hour intravenous infusion) every 2 weeks for 6 weeks. Treatment was continued until progression of disease was observed. RESULTS: All patients were assessable for toxicity and 37 of 41 patients were assessable for response. Patient characteristics were: sex (male, 28; female,13), median age 60 years (range, 20 to 77 years), and median Eastern Cooperative Oncology Group performance status of 1. Response was evaluated every 6 weeks. Of 37 assessable patients, one complete and 15 partial remissions were observed (overall response rate, 43%). Stable disease was observed in 12 patients (32%) and progressive disease in nine patients (24%). The median overall survival was 9.6 months. WHO grade 3 or 4 hematologic toxicities included neutropenia in two patients (4.9%) and thrombocytopenia in one patient (2.4%). Other WHO grade 3 or 4 toxicities included diarrhea in three patients (7.3%) and vomiting in two patients (4.9%). There were no cases of grade 3 peripheral neuropathy and no treatment-related deaths. CONCLUSION: Biweekly fluorouracil, folinic acid, and oxaliplatin is active and well-tolerated in patients with advanced gastric cancer. Response rates, time to progression, and overall survival were comparable to those achieved with other combination chemotherapy regimens, including FOLFOX6, with significantly less toxicity. 相似文献

Twenty-seven patients with advanced measurable colorectal carcinoma were treated with a combination protocol consisting of folinic acid (FA) 200 mg/m2 i.v. bolus followed by 5-fluorouracil (5-FU) 550 mg/m2, and cisplatin (CIS) 20 mg/m2 each administered as a 2-hour i.v. infusion. Treatment was given on 4 consecutive days at 3- to 4-weekly intervals. Of 25 evaluable patients, 1 achieved complete remission and 5 partial remission for an overall response rate of 24%, while 9 patients (36%) had stable disease. Two out of 6 responders had previously progressed on 5-FU-containing regimens. The 95% confidence interval for response is 7-41%. Median survival time for all 27 patients enrolled in the study is 27+ weeks. Tolerance was remarkable and consisted primarily of mild and reversible gastrointestinal symptoms and myelosuppression. This 3-drug-regimen had significant palliative activity in our patient population. Its definitive role in the treatment of metastatic colorectal cancer as well as the potential improvement of the therapeutic index of 5-FU/FA by addition of CIS, require further evaluation in a randomized phase III trial. 相似文献

Previous small phase II trials have demonstrated that the combination of 5-fluorouracil (5FU) and cisplatin(CDDP) could have clinical activity in metastatic biliary tract cancer. This randomised phase II trial was designed to assess the activity and safety of a high-dose infusional weekly 5FU alone (HDFU) and the combination of 5FU, folinic acid (FA) and CDDP. Patients were included if they had histologically proven locally advanced or metastatic biliary tract carcinoma, World Health Organisation (WHO) performance status < or = 2, bilirubin <2 x upper normal limit, adequate haematological and renal functions and had not received prior chemotherapy, even in the adjuvant setting. Treatments: Arm A (HDFU) consisted of cycles of 5FU 3 g/m(2) intravenously (i.v.), 24 h infusion, weekly, for 6 weeks, followed by 1 week rest, every 7 weeks; Arm B (5FU+FA+CDDP) consisted of cycles of 5FU 2.0 g/m(2) i.v. with folinic acid 500 mg/m(2), 2 h-infusion, weekly, for 6 weeks, followed by 1 week rest plus cisplatin 50 mg/m(2), once every two weeks, for 6 weeks, followed by 1 week rest, every 7 weeks. From February 1997 to June 1999, 58 patients were randomised (29 in each arm). Patients had a median age of 58 years in Arm A and 62 years in Arm B, locally advanced disease was present in 21% of the patients in Arm A and 11% in Arm B. WHO performance status of 0/1/2 was noted in 48%/45%/7% of the patients in Arm A and 54%/43%/4% in Arm B. In both arms, the most common metastatic sites were the liver and peritoneum. Twenty-eight patients were eligible in each arm and one patient did not start the allocated therapy in Arm B. The median number of cycles was 2 [range 1-12] in Arm A and 2 [range 1-6] in Arm B. Responses for the eligible patients who started their allocated therapy were as follows: Complete Response (CR) 0% in Arm A, 4% in Arm B, Partial Response (PR) 7% in Arm A, 15% in Arm B resulting in an overall response rate [95% CI] of 7.1% in Arm A [0.9-23.5%] and 19% [6.3-38.1%] in Arm B. Disease stabilisation was observed in 46% in Arm A and 44% in Arm B. National Cancer Institute of Canada (NCIC) grade 3-4 adverse events (% of patients in Arm A/Arm B) were neutropenia 4%/26%, thrombopenia 0%/7%, stomatitis 0%/4%, vomiting 7%/14%, diarrhoea 0%/11% and neurotoxicity 4%/0%. There was one early toxic death in Arm B. The median overall survival (OS) [95% CI] was in Arm A/Arm B: 5.0 [4.0-7.4] months/8.0 [5.8-11.8] months and the median progression-free survival (PFS) was 3.3 [1.7-4.7] months/3.3 [2.3-6.7] months. Cisplatin in combination with 5FU+FA showed a higher activity than HDFU, but was more toxic. These results are not sufficient to start a phase III trial. However, our group is planning a phase III trial comparing 5FU+folinic acid versus the same schedule+oxaliplatin a platinum analogue. 相似文献

The aim of the study was to assess the response rate and toxicity of high-dose 24 h infusion of 5-fluorouracil (5FU) in metastatic adenocarcinoma of the pancreas. Patients with measurable disease, performance status 0-2, and no prior chemotherapy were registered to receive cycles of leucovorin (LV) 500 mg/m2 (or l-LV 250 mg/m2 over 1 h followed by 5FU 2.6 g/m2 over 24 h, weekly for 6 weeks, followed by a 2-week rest. The main endpoints were the response rate and toxicity. From 37 patients, 36 were the analysed for toxicity, and 33 were eligible and analysed for response. The median age was 59 years (range 28-74 years), and the median performance status was 1. Partial response was observed in three patients (9%) (95% Confidential Interval (CI): [2-24]%). Main grade 3/4 National Cancer Institute (NCI) common toxicity criteria toxicities (patients) were diarrhoea (n = 3), vomiting (n = 2) and hand-foot syndrome (n = 5). Median time to progression was 7 weeks (95% CI: [6.4-11.7] weeks) and median survival 19 weeks (95% CI: [12-35] weeks). In conclusion, high-dose 5FU and folinic acid is well tolerated, but has only modest activity in pancreatic cancer. 相似文献

BACKGROUND: The aim of this study was to determine the maximum-tolerated dose (MTD) and the recommended dose of irinotecan and oxaliplatin with a fixed 5-fluorouracil (5-FU)/leucovorin (LV) regimen in patients with metastatic solid tumors. PATIENTS AND METHODS: The trial was designed to evaluate escalating doses of oxaliplatin and irinotecan, starting at 60 mg/m2 and 90 mg/m2, respectively, given at day 1 with the full-dose LV5FU2 regimen, given on days 1 and 2 as follows: folinic acid 200 mg/m2 followed by 5-FU 400 mg/m2 bolus and 600 mg/m2 22 h continuous infusion, every 2 weeks. The second cohort of patients was treated at the recommended dose for oxaliplatin and irinotecan with the simplified LV5FU regimen: on day 1, a 2-h infusion of folinic acid (400 mg/m2), followed by a 10-min intravenous bolus of 5-FU (400 mg/m2), followed by a continuous infusion of 5-FU (2400 mg/m2) over 46 h. RESULTS: Thirty-four patients were treated at the following dose levels (oxaliplatin/irinotecan mg/m2): 60/90, 60/120, 85/120, 85/150, 85/180, 85/200 and 85/220 and seven patients were treated at the recommended dose with the simplified LV5FU scheme. The MTD was reached at dose level 85/220 mg/m2 but the recommended dose chosen for the second step was 85/180 mg/m2 to keep a better compliance with the biweekly schedule. Main grade 3/4 toxicities per patient included the following: neutropenia in 78% (febrile episodes in 12%), diarrhea in 27%, nausea/vomiting in 24% and peripheral neuropathy in 37% (Lévi's scale). Antitumor activity was observed at almost all dose levels. Most objective responses were observed in digestive malignancies, since 10 out of 11 were obtained in five colorectal cancers, two pancreatic cancers, two cholangiocarcinoma and one gastric cancer. CONCLUSION: The recommended dose for the triple association is 85/180 mg/m2 of oxaliplatin and irinotecan, respectively, with LV5FU2 or simplified LV5FU. The antitumor activity in gastrointestinal malignancies should be evaluated in phase II studies in different tumor types. 相似文献

Twenty patients with documented progression after two or three cisplatin-based regimens for advanced epithelial ovarian carcinoma were treated with high-dose folinic acid (200 mg/m2), 5-fluorouracil bolus (400 mg/m2) and continuous infusion (600 mg/m2) for two consecutive days every two weeks. One clinically complete and two partial responses were observed in 16 evaluable patients, with 5 remaining stable. Median survival was 9 months. Toxicity was mild. This combination achieved a 19% (95% confidence interval 4%-46%) response rate in heavily pretreated cisplatin-resistant patients. 相似文献

PURPOSE: This Nordic multicenter phase II study evaluated the efficacy and safety of oxaliplatin combined with the Nordic bolus schedule of fluorouracil (FU) and folinic acid (FA) as first-line treatment in metastatic colorectal cancer. PATIENTS AND METHODS: Eighty-five patients were treated with oxaliplatin 85 mg/m(2) as a 2-hour infusion on day 1, followed by a 3-minute bolus injection with FU 500 mg/m(2) and, 30 minutes later, by a bolus injection with FA 60 mg/m(2) every second week. The same doses of FU and FA were also given on day 2. RESULTS: Fifty-one of 82 assessable patients achieved a complete (n = 4) or partial (n = 47) response, leading to a response rate of 62% (95% CI, 52% to 72%). Nineteen patients showed stable disease, and 12 patients had progressive disease. Thirty-eight of the 51 responses were radiologically confirmed 8 weeks later (confirmed response rate, 46%; 95% CI, 36% to 58%). The estimated median time to progression was 7.0 months (95% CI, 6.3 to 7.7 months), and the median overall survival was 16.1 months (95% CI, 12.7 to 19.6 months) in the intent-to-treat population. Neutropenia was the main adverse event, with grade 3 to 4 toxicity in 58% of patients. Febrile neutropenia developed in seven patients. Nonhematologic toxicity consisted mainly of neuropathy (grade 3 in 11 patients and grade 2 in another 27 patients). CONCLUSION: Oxaliplatin combined with the bolus Nordic schedule of FU+FA (Nordic FLOX) is a well-tolerated, effective, and feasible bolus schedule as first-line treatment of metastatic colorectal cancer that yields comparable results compared with more complex schedules. 相似文献
