We report the results of an expanded trial of 5-fluorouracil (FUra) combined with high-dose
folinic acid
for treatment of patients with advanced colorectal or gastric adenocarcinoma. In each treatment course, the patients received both FUra (340-400 mg/m2/day by iv infusion over 15 minutes) and
folinic acid
(200 mg/m2/day by iv bolus) for 5 consecutive days, with a 21-day interval between courses. Eighty-six patients with colorectal carcinoma were evaluated. The combined complete response (CR) and partial response (PR) rates were 39% for 54 patients who did not receive prior chemotherapy and 22% for 32 patients who had previously received chemotherapy. Four patients who were previously resistant to FUra attained objective responses. The median time to disease progression for the 28 responders was 10 months. The median survival time of responders was 19.5 months, and the probability of their being alive at 2 years was 40%. Of 27 patients with gastric adenocarcinoma, 13 (48%) responded to therapy. Their median time to disease progression was 5.5 months. The median survival time of responders was 11 months, and their probability of being alive at 15 months was 30%. Toxicity was within acceptable limits. Toxic effects included
stomatitis
, diarrhea, conjunctivitis, skin rash, and mild myeloid hypoplasia. In a separate study, plasma concentrations of L-folates above 10(-5) M were achieved after a rapid single iv injection of 200 mg/m2 of
folinic acid

We report the results of an expanded trial of 5-fluorouracil (5-FU) combined with high-dose
folinic acid
for treatment of patients with advanced colorectal or advanced gastric adenocarcinoma. In each treatment course, the patients received both 5-FU (340 to 400 mg/m2/d by intravenous (IV) infusion for a period of 15 minutes) and
folinic acid
(200 mg/m2/d by IV bolus) for 5 consecutive days, with a 21-day interval between courses. Eighty-six patients with colorectal carcinoma were evaluated. The combined complete and partial response rates were 39% for 54 patients who did not receive prior chemotherapy and 22% for 32 patients who had previously received chemotherapy. Four patients who were previously resistant to 5-FU attained objective responses. The median time to disease progression for the 28 responders was 10 months. The median survival time of responders was 19.5 months, and the probability of their being alive at 2 years was 40%. Of 27 patients with gastric adenocarcinoma, 13 (48%) responded to therapy. Their median time to disease progression was 5.5 months. The median survival time of responders was 11 months, and their probability of being alive at 15 months was 30%. Toxicity was within acceptable limits. Toxic effects included
stomatitis
, diarrhea, conjunctivitis, skin rash, and mild myeloid hypoplasia. In a separate study, plasma concentrations of L-folates greater than 10(-5) mol/L were achieved after a rapid single IV injection of 200 mg/m2 of
folinic acid
. Comparisons of our results with those reported in previous studies on 5-FU administered as a single agent suggest that, in advanced colorectal and gastric adenocarcinoma,
folinic acid
administered in high doses enhances the effectiveness of 5-FU administered concomitantly. Furthermore, some colorectal tumors that were previously resistant to 5-FU become sensitive to this drug. The survival of the patients who responded to therapy was markedly improved over that observed in reported series of untreated patients with advanced colorectal and gastric adenocarcinomas.

In order to determine the clinical applicability of the in vitro observation of enhanced cytotoxicity of 5-fluorouracil (5-FU) in the presence of excess reduced folates, the Southwest Oncology Group (SWOG) performed a randomized trial evaluating two dose schedules of 5-FU and
folinic acid
(FA) in 128 patients with metastatic colorectal cancer. Of 125 eligible patients, 62 were randomized to receive bolus FA (200 mg/m2 days 1 through 4) in addition to 5-FU (1,000 mg/m2 days 1 through 4) by continuous four-day infusion (infusion arm), while 63 were randomized to receive bolus FA (200 mg/m2 days 1 through 5) in addition to 5-FU (325 mg/m2 days 1 through 5) by bolus injection (bolus arm). The toxicities of the two schedules differed, with
stomatitis
being more severe in the infusion arm and leukopenia being more severe in the bolus arm. The response rates and survival data for the two arms are nearly identical. The median survival of patients on the infusion arm is 11.0 months and of patients on the bolus arm, 10.3 months. The infusion arm produced one complete response (CR) and 12 partial responses (PRs), for a major response rate of 21% of eligible patients. The bolus arm produced three CRs and 11 PRs, for a major response rate of 22% of eligible patients. The response rate produced is minimally superior to recent cooperative group studies of colorectal cancer, but the response rate and survival experience are within the range of experience for treatment with 5-FU alone.

We report the results of a therapeutic trial in patients with rectocolic and gastric metastatic adenocarcinomas. This trial is based on experimental evidence that an excess of reduced intracellular folic acid increases the cytotoxicity of fluoropyrimidines. The treatment consists of 5-fluorouracile (5-FU) (370 to 400 mg/m2/24 h) and
folinic acid
in high doses (200 mg/m2: 24 h) given simultaneously for 5 consecutive days; the interval between courses is 21 days. Thirty patients with measurable rectocolic adenocarcinomas were evaluated. They were divided into two groups: 16 patients had had no previous chemotherapy and 14 had not responded to chemotherapy with 5-FU alone or associated with other cytostatic drugs. Response rates were 56% in the first group and 21% in the second. Five patients with measurable gastric adenocarcinomas were also evaluated; none had received previous chemotherapy. A partial response was recorded in three of these patients. Toxicity of the therapeutic regimen was acceptable.
Stomatitis
was the most common toxic side-effect. In patients with severe adverse side-effects recurrence was efficiently prevented by decreasing the daily dose of 5-FU to 30 mg/m2 during subsequent courses. We conclude that in the tumors studied
folinic acid
in high doses can improve the antitumoral effect of 5-FU and induce a response to this agent in some rectocolic tumors which were previously resistant.

41 patients (pilot study-I) and 50 patients (multicenter study II) were randomized to receive as systemic chemotherapy for 6 courses with 5 FU alone (A) [440 (I)-450 (II) mg/m2 IV bolus, 5/21 days] or
folinic acid
followed by 5 FU (B) (respectively 200 and 370 mg/m2 IV bolus, 5/21 days). In the multicenter trial, oral levamisole at the dose of 150 mg/day (3/14 days) was added to chemotherapy for one year. Ten patients in study I and 19 patients in study II also received a post-operative course of intra-portal chemotherapy. Toxicity was evaluated respectively on 232 (I) and 276 (II) courses. Clinical limiting toxicities were
stomatitis
and diarrhea. In protocol II, a significant enhancement of grades 3-4 granulocyte toxicity was seen (17.3% of courses in II vs only 3.4% in I; p < 0.001). This was especially recorded in the group treated with 5-FU alone (26% of courses in A vs 11% in B; p < 0.001). Levamisole was therefore stopped in 12 cases (10 cases in A; 2 cases in B).

Fourteen patients with malignant gliomas were entered on a phase II study of 5-fluorouracil 300-370 mg/m2 plus
folinic acid
200 mg/m2 x 5 days q4 weeks. To be eligible, patients could not have received more than 1 prior chemotherapy regimen. A single patient with a recurrent oligodendroglioma responded. Toxicity (predominantly
stomatitis
, diarrhea, and granulocytopenia) was tolerable and was similar to that seen in studies of 5-fluorouracil plus
folinic acid
in other tumor types. This regimen has minimal activity in recurrent malignant gliomas.

A total of 44 women with advanced breast cancer who had failed first- and second-line chemotherapy were given combination chemotherapy consisting of
folinic acid
(FA), 5-fluorouracil (5-FU) and mitomycin C (MMC). The treatment schedule was: 200 mg/m2 FA and 400 mg/m2 5-FU given i.v. over 2 h for 5 days plus 5 mg/m2 MMC given i.v. on days 3-5; in 19 patients with an Eastern Cooperative Oncology Group (ECOG) performance status of 3-4 and bone marrow depression, the MMC dose was 3 mg/m2 given i.v. on days 3-5. In all, 41 patients were evaluable for response; 15 had a partial remission (PR), 18 had stable disease (SD), and 8 showed progressive disease (PD). The median response duration was 6 months and the median survival was 10 months. Toxicity was mild and consisted mainly of
stomatitis
, diarrhea, and leukopenia. A rapid improvement in performance status was noted in responding patients. A striking result was the reduction of analgesics in most cases and their complete withdrawal in responding patients. This combination chemotherapy achieved satisfactory effectiveness and improved the quality of life of patients.

The main purpose of this trial was to investigate the activity of a less toxic regimen in patients with advanced gastric carcinoma regarding response rate and survival. We report on a pilot study of 20 patients treated with the combination of 5-fluorouracil and
folinic acid
. 5-fluorouracil was administered at a daily dose of 450 mg/m2 followed by
folinic acid
200 mg/m2 for four consecutive days every four weeks. The overall response rate was 15% with one complete and two partial responders. The median duration of response was 11, 10 and 10 months respectively. The median survival of all patients was 9 months. Toxicity was mild and consisted primarily of diarrhea.
Stomatitis
and myelosuppression occurred rarely. In conclusion, the combination of 5-fluorouracil and
folinic acid
has moderate activity in gastric cancer, while median survival appears similar to the other more intensive regimens. The combination is very well tolerated with minimal toxicity. A detailed review of the literature regarding the effectiveness of the above regimens on response rate, overall survival and toxicity is also presented.

In order to assess the maximum tolerated dose of 5'-deoxy-5-fluorouridine (5dFUR) combined with a cisplatin (20 mg/m2 i.v.) and L-
folinic acid
(100 mg/m2 i.v.), 5-day schedule 19 consecutive chemotherapy-naive patients affected by advanced or recurrent carcinoma of the head and neck were entered in this phase I trial. Doses of 5dFUR were escalated from a starting level of 2,000 mg/m2/day up to 3,000 and 5,000 mg/m2/day. At the latter step the dose-limiting acute toxicities were
stomatitis
and diarrhea, which were of WHO grade 3-4 and occurred in 3 and 1 out of 4 evaluated patients, respectively. Other grade 3 acute toxicities were leukopenia, anemia, renal impairment, and neurologic symptoms, observed in 1 patient each. Furthermore, one possibly treatment-related death was registered among patients entered in the highest dose level. Eleven out of 19 patients (58%; 95% CI:34-80%) showed a complete (2 cases) or partial (9 cases) response to this treatment, regardless of the 5dFUR dosage employed. From our results we may define the maximum tolerated dose of 5dFUR to be associated with cisplatin and L-folin acid used in this trial as 3,000 mg/m2/day x 5 days. Assessment of the real activity of this combination chemotherapy deserves further studies.

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.
