After informed consent 21 patients with advanced head and neck cancer resistant to folinic acid/5-fluorouracil (FA/5FU + cisplatin) were treated with weekly FA/5FU plus low dose hydroxyurea (HU) to evaluate if HU could further modulate 5FU antineoplastic activity. Five patients achieved a partial response (23.8%) which was short-lived (mean duration 6.5 months). Three patients (14%) had stable disease and 13 (62%) progressed. Among responders, four patients had epidermoidal carcinoma and one had clear cell carcinoma. Treatment was well tolerated and 5FU-related toxicity was not apparently worsened by the addition of HU. The most frequent toxicities were nausea/vomiting (81%), diarrhea (52%) and leukopenia (57%). Grade 3 nausea/vomiting and leukopenia were recorded in only 19 and 9% of cases, respectively. One patient had grade 1 cutaneous toxicity and a second patient showed a hand-foot syndrome. These results suggest that HU may further positively modulate 5FU antineoplastic activity.

Twenty-eight patients with refractory advanced malignancies were treated with a 24 hr infusion of 5-fluorouracil (5-FU), Leucovorin (LV), and N-(phosphonacetyl)-L-aspartic acid (PALA) weekly. Twenty-seven patients were evaluable for the assessment of toxicity and anti-tumor activity. PALA was administered as intravenous bolus over 15 min at a fixed dose, 250 mg/m2 24 hr before the start of 5-FU and LV infusions. 5-FU was initially administered at 750 mg/m2 and was incrementally increased to 2600 mg/m2. LV was administered in a fixed dose of 500 mg/m2 concurrently with 5-FU over a 24-hr period. The course was repeated weekly. Diarrhea, stomatitis, nausea, and vomiting were among dose-limiting toxic effects. Other toxicities observed were hand-foot syndrome, hair loss of scalp/eyelashes, overall weakness, rhinitis, and chemical conjunctivitis. Maximum tolerated dose (MTD) of 5-FU in this combination and schedule was 2600 mg/m2. Seven of 14 patients treated at 2600 mg/m2 were able to tolerate the chemotherapy on a weekly basis without interruption. The other seven patients required dose de-escalation, a majority of whom contained 5-FU at a dose of 2100 mg/m2. Twenty-three of 27 patients had been previously treated. Eight patients achieved a partial response, all of whom were previously treated, except three patients. A complete response was observed in a patient with pancreatic carcinoma, previously untreated. Overall response rate for the patients who were treated at the 5-FU dose of 2100 mg/m2 or 2600 mg/m2 is 9 of 18 patients (50%).

Twenty-eight patients with refractory advanced malignancies were treated with a 24-hour infusion of 5-fluorouracil (5-FU), leucovorin (LV), and N-(phosphonacetyl)-L-aspartic acid (PALA) weekly. Twenty-seven patients were evaluable to assess toxicity and antitumor activity. The PALA was administered as an intravenous bolus over 15 minutes at a fixed dose (250 mg/m2) 24 hours before the start of the 5-FU and leucovorin infusions. Initially the dose of 5-FU was 750 mg/m2; this was increased incrementally to 2600 mg/m2. The LV was administered in a fixed dose of 500 mg/m2 concurrently with the 5-FU over a 24-hour period. This regimen was repeated weekly. Diarrhea, stomatitis, nausea, and vomiting were among the dose-limiting toxicities. Others were hand-foot syndrome, hair loss of the scalp and eyelashes, overall weakness, rhinitis, and chemical conjunctivitis. The maximum tolerated dose of 5-FU in this combination and schedule was 2600 mg/m2. Seven of 14 patients treated with 2600 mg/m2 were able to tolerate the chemotherapy on a weekly basis without interruption. The other seven patients required dose reductions, but most received 5-FU at a dose of 2100 mg/m2. Twenty-three of 27 patients were treated previously. Eight patients had a partial response; five of these were treated previously. A complete response was observed in one patient with pancreatic carcinoma, previously untreated. The overall response rate for patients treated with 2100 or 2600 mg/m2 of 5-FU was nine of 18 patients (50%). Three of four previously untreated patients with pancreatic cancer responded to this treatment (two responded partially, and one had a complete response). One of three heavily pretreated patients with non-small cell lung cancer had a partial response as did a patient with breast cancer. Four of ten patients with colorectal cancer responded to the treatment (four partial responses), of whom three had been treated previously.

We have recently demonstrated that continuous-infusion (CI) 5-fluorouracil (FU) eradicates human colon carcinoma cells made resistant to bolus FU in vitro. In addition, in the same experimental system, the mechanisms of resistance to pulse and CI FU were found to be different. These observations led us to test the clinical activity of a standard regimen of CI FU (300 mg/m2 per day) in a cohort of 15 patients with advanced measurable colorectal cancer who were in progression after having failed to respond to bolus treatment with FU alone (3 patients) or FU combined with high-dose 6-S-leucovorin (LV) (12 patients). The median age of the patients was 68 years, and their median Eastern Cooperative Oncology Group performance status (ECOG PS) was 1. No myelotoxicity was observed. Mild diarrhea, mucositis, and vomiting occurred in 32%, 26%, and 19% of the patients, respectively, with no WHO grade 3 or 4 episodes being noted. In all, 6 of 15 patients complained of hand-foot syndrome, which was severe in 2 instances, lasting approximately 1 week. Overall, 1 partial response and 6 instances of disease stabilization, including 3 minor responses, were obtained both in patients who had been pretreated with pulse FU alone and in patients who had failed first-line treatment with FU + LV. Finally, 8 patients failed CI FU. In conclusion, these results, obtained in patients who were clearly progressing after having failed first-line treatment, support our experimental finding that resistance to bolus FU may be overcome by CI FU and extend this possibility to patients who are resistant to bolus treatment with FU + LV.

Phase II study results demonstrating high efficacy and low toxicity for a weekly schedule of high-dose 5-fluorouracil/folinic acid (5-FU/FA) in intensively pretreated metastatic breast cancer patients prompted the addition of paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) to this regimen in a phase I/II trial in outpatients: high-dose 5-FU (24-hour infusion)/FA (2-hour infusion preceding 5-FU) is given for 6 weeks (days 1, 8, 15, 22, 29, and 36), with paclitaxel (3-hour infusion) administered on days 1 and 22; 2 weeks' rest follows. Folinic acid 500 mg/m2 was administered throughout; the respective 5-FU doses for dose levels 1 through 3 were 1.5, 1.8, and 2.0 g/m2 with paclitaxel 135 mg/m2. Dose level 4 (500 mg/m2 FA, 2.0 g/m2 5-FU, and 175 mg/m2 paclitaxel) was chosen for phase II evaluation. To date, 46 patients with bidimensionally measurable disease (four each at dose levels 1, 2, and 3, and 34 at dose level 4) have been entered. The 12 patients treated at dose levels 1 through 3 were titrated to level 4 doses when phase II began; 35 patients are evaluable for response. The median age is 46 years, and the median number of metastatic sites is 2.5. Fourteen patients had received adjuvant chemotherapy, nine chemotherapy for metastasis, and 23 chemotherapy both adjuvantly and for metastasis. Of 31 anthracycline-treated patients, 27 had anthracycline-resistant disease. No dose-limiting toxicity appeared until dose level 4, when grade 3 or 4 leukopenia and diarrhea occurred in 15 and eight, respectively, of 108 cycles. Mild to moderate mucositis, hand-foot syndrome, myalgia, and nausea/vomiting occurred in 20% to 40% of cycles. One (3%) of the 35 patients had a complete response, 18 (51%) had partial responses, 14 (40%) had stable disease, and two (6%) had disease progression. Eleven (55%) of 20 evaluable patients with anthracycline-resistant disease responded (95% confidence interval, 34% to 76%). Median time to maximum response was 2 months, and the remission duration was 8+ months. Median survival time has not been reached. Paclitaxel and weekly high-dose 5-FU/FA was well tolerated and highly effective, even in patients with anthracycline-resistant metastatic breast cancer. The regimen can be administered safely to outpatients.

A total of 55 patients with measurable colorectal metastatic carcinoma were studied to evaluate the impact on toxicity, response, and survival of protracted venous infusion (PVI) 5-FU 200 mg/m2 per day with Cis-DDP 80 mg/m2 or carboplatin 300 mg/m2 every 3 weeks, 1-hour infusion. Patients received continuous uninterrupted therapy until there were signs or symptoms of toxicity. Both 5-FU and cisplatin were withheld when patients experienced grade II stomatitis and diarrhea, severe nausea or vomiting not controlled by standard antiemetic therapy, and clinically significant hand-foot syndrome. The toxicity was neurological (20% grade 2 and 3) hematological (13% grade 2) and dermatological (11% grade 2). The overall response (CR+PR) was 24% with a median survival of 13 months. The results of our study show that there is no improvement in response rate, response duration or survival compared with historical trials. However, this study does confirm the valuable palliative role of the protracted 5-FU infusion treatment. Colorectal carcinoma is one of the most common neoplasms in Western societies, being second only to lung cancer as a cause of death from malignancy. The management of nonmetastatic primary disease in surgical, with adjuvant chemotherapy for those at high risk of relapse. However, for those with metastatic disease at diagnosis or recurrent disease after resection, cytotoxic chemotherapy is the treatment of choice and fluorouracil (5-FU) is the most active cytotoxic agent in this disease, with a response rate of approximately 20%. Efforts to improve the response rate have focused on the use of agents to modulate 5 FU. The Southwestern Oncology Group (SWOG) study reported by Leichman et al. (1) and a study from the United Kingdom by Hill et al. (2) compared conventional FU to modulated FU and found no improvement in response rate or survival. In the SWOG study, two different schedules of bolus FU and LV were compared with bolus FU alone and to continuous infusion FU administered alone or modulated by LV or PALA. In this study, the results obtained with bolus FU were superior to most of the studies in the literature: The response rate was 26%, and the median survival was 14 months. The high- and low-dose LV and FU groups showed response rates and survival similar to bolus FU alone. However, in 12 previously reported randomized studies comparing FU and LV or FU alone, nine reported that the combination of FU and LV produced significant increases in response rates and two reported significant increase in survival (3, 4). Many of these trials used the dose schedules reported in the SWOG trial. Protracted venous infusion (PVI) 5-FU has been shown to have superior efficacy with less toxicity in colorectal cancer when compared to bolus 5-FU and synergy between cisplatin and 5-FU has been demonstrated in vitro. Consequently, we have investigated the efficacy of the combination of bolus cis or carboplatin and PVI 5 FU in 55 patients with advanced colorectal cancer using survival, response rate, symptomatic response, and toxicity as study endpoints.

Previous report suggested that weekly 24-hour infusion of high-dose 5-fluorouracil (5-FU) and leucovorin is a highly active and relatively low toxic regimen for the treatment of colorectal carcinoma (J Clin Oncol 9: 625-30, 1991). This phase II study was conducted to test this important observation by a slightly modified regimen in a larger group of patients. The weekly HDFL regimen consisted of 5-FU 2600 mg/m2/week and leucovorin 300 mg/m2/week (maximum 500 mg) in a 24-hour intravenous infusion. Between February 1992 and December 1995, a total of 42 patients with non-resectable, recurrent or metastatic colorectal adenocarcinoma were enrolled onto the study. Twenty-nine (69.0%) patients had prior exposure to lower-dose 5-FU. There were 22 men and 20 women with median age of 60 (20-75) years. They received a total of 855 and an average of 20.4 (4 to 65) courses of HDFL chemotherapy. Most patients were treated at outpatient clinics and the drugs were infused by an ambulatory pump system via a Port-A catheter. The median duration of follow-up was 22 months. ECOG Gr 2-3 stomatitis, diarrhea, nausea, and vomiting developed in 6 (14.3%), 6 (14.3%), 5 (11.9%), and 5 (11.9%) patients, respectively. Twenty (47.6%) patients had developed hand-foot syndrome. There was no hematological toxicities except 3 (7.1%) patients developed ECOG Gr 1-2 leucopenia. The overall response rate was 42.9% (28%-59%, 95% C.I.) with 2 complete responses and 16 partial responses. Eight (61.5%; 31%-86%, 95% C.I.) of 13 patients, who had no previous 5-FU exposure, responded (1 complete response, 7 partial responses). Ten (34.5%, 17%-54%, 95% C.I.) of 29 patients, who had had previous lower-dose 5-FU exposure, responded (1 complete response and 9 partial responses). The median duration of response was 5 months (1+ to 23+ months). The median overall survival of the whole group of 42 patients and the 18 responders was 10 and 22 months, respectively. Our data supported the original results of HDFL regimen in the treatment of colorectal cancers. HDFL regimen can be used either as first-line or second-line treatment for non-resectable, recurrent or metastatic colorectal cancers.

The aim of this study was to evaluate the efficacy and tolerance of second-line continuous 5-fluorouracil (5FU) chemotherapy combined with folinic acid and mitomycin C in patients with advanced colorectal cancer who progressed on first-line chemotherapy. From June 1992 to April 1994, 24 consecutive patients, median age 59.7 years (range 41-73), performance status (PS) 0 to 2, were treated as second-line chemotherapy with mitomycin C, 7 mg/m2 every 4 weeks, folinic acid 200 mg/m2/day as a 2 h infusion followed by 400 mg/m2 of 5FU bolus and 600 mg/m2 continuous 5FU infusion for 22 h on days 1 and 2 and every 14 days; 19 patients did not respond to folinic acid and 5FU bolus regimen (in 2 patients, this was associated with pirarubicin in a continuous hepatic artery infusion) and 3 did not respond to irinotecan; 2 patients had disease progression during adjuvant chemotherapy with folinic acid and 5FU bolus. Tumor response was assessed every 12 weeks. One patient died before evaluation and 1 was lost to follow-up after 3 cycles; 7/24 patients had an objective response (29.2%, 95% confidence interval (CI): 11.0-47.4) including 2 complete responses; 7 additional patients had stable disease or minor response. Mean duration of response was 7.5 months. Median survival was 10 months and survival at 1 year was 39.4% (95% CI: 4-59.4). One patient who had a disease progression under irinotecan presented an objective response. No iatrogenic deaths occurred, nor was any grade 3 or 4 myelotoxicity seen. No hand-foot syndrome nor any cardiotoxicity arose but 2 grade II alopecia were seen. Digestive toxicities were the most frequent but with only 4 grade III toxicities (1 vomiting, 1 mucositis and 2 diarrhea) and no grade IV. With nearly 30% objective response and acceptable toxicity this treatment seems to offer a good alternative in the treatment of advanced colorectal cancers after the failure of first-line chemotherapy.

There are few treatment options available for patients with metastatic breast cancer who have failed anthracycline- and paclitaxel-based chemotherapy. Xeloda (capecitabine) is a novel selectively tumoractivated fluoropyrimidine carbamate producing clinically active levels of 5-fluorouracil (5-FU) at the tumor site. Xeloda is active in breast cancer and is administered orally. It is the only registered treatment for patients in whom anthracycline and taxoid treatment has failed. In a phase II trial of 163 paclitaxel-refractory patients with metastatic breast cancer, the overall response rate with Xeloda was 20%, with three complete responses, and the median survival was 12.8 months. A total of 20% of patients experienced a Clinical Benefit Response (a composite assessment of clinical benefit). Furthermore, Xeloda was well tolerated; the most common treatment-related adverse events were hand-foot syndrome, diarrhea, nausea, vomiting, and fatigue. Two additional studies of Xeloda in patients with metastatic breast cancer have also been completed. In the first study, patients with anthracycline-resistant metastatic breast cancer received either Xeloda or paclitaxel; the response rates were 36 and 26%, respectively. In the second study, women aged >/=55 years received first-line treatment with either Xeloda or cyclophosphamide/methotrexate/5-FU. The response rates were 25 and 16%, respectively. These studies show that Xeloda is an active agent in the treatment of metastatic breast cancer with the additional advantage of oral administration.

This is a phase I dose-escalation study of uracil and tegafur (in a molar ratio of 4:1 [UFT]) administered in combination with calcium folinate and paclitaxel in metastatic breast cancer. This trial was initiated to 1) determine the maximum tolerated dose and dose-limiting toxicities of UFT plus calcium folinate (Orzel) administered three times per day for 21 days in combination with paclitaxel; and 2) define the appropriate dose for phase II testing. Thus far, 14 patients have been accrued to three dose levels. Two patients developed dose-limiting toxicities at dose level 3. One patient experienced grade 3 hypotension. A second patient experienced grade 3 vomiting, grade 4 diarrhea, and severe hand-foot syndrome. Two partial responses and one complete response have been observed. Early trends suggest that this regimen is active in metastatic breast cancer and is well tolerated. Completion of this study is anticipated in 1999.
