5-Fluorouracil (5-FU) is one of the important antineoplastic agents for the treatment of gastrointestinal cancers. The biochemical modulation of 5-FU by various drugs has brought about the two combinations of 5-FU/folinic acid (FA) and 5-FU/alpha-interferon (IFN), which have shown clinical activity in phase II and III trials, especially in colorectal cancer. The experience with both combinations in upper gastrointestinal cancers, however, is limited. In esophageal cancer, two phase II studies with 5-FU/IFN reported seven (27%) objective remissions in 26 patients, indicating superiority of 5-FU/IFN over 5-FU monotherapy. Trials with 5-FU/FA alone are lacking in esophageal cancer. The modulation of 5-FU by IFN or FA failed to show clinically significant activity in pancreatic cancer. However, in gastric cancer, 5-FU/FA and 5-FU/IFN seem to induce higher complete and overall remission rates in advanced gastric cancer compared with 5-FU alone. With the daily times five schedule of 5-FU/FA, 27% objective remissions were achieved; in combination with other cytotoxic drugs, such as etoposide, anthracyclines, cisplatin, mitomycin, or methotrexate, objective response rates up to 50% and more were reported.

A group of 20 patients with gastric cancer, refractory to or with no change after two or three cycles of carboplatin were treated with etoposide/folinic acid/5-fluorouracil (ELF). An objective remission rate of 45% (9/20), a median remission duration of 8 months and a median survival time of 11 months were achieved. Toxicities were mild to moderate only. These results are comparable to those being achieved with ELF in previously untreated gastric cancer patients and confirm its efficacy and good tolerability.

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.

Thirty-four consecutive patients with measurable advanced gastric cancer were treated in a disease oriented Phase II study with high-dose folinic acid (HDFA) 300 mg/m2 10 min. inf., followed immediately by etoposide 120 mg/m2 50 min. inf., followed immediately by 5-fluorouracil (5-FU) 500 mg/m2 10 min. inf., given on day 1,2,3 (ELF). Courses were repeated every 22-28 days. All patients who entered this study were older than 65 years or had underlying cardiac disease. Thirty-three patients were evaluable for response and toxicity (greater than or equal to 1 course). One patient was lost to follow up. The overall response rate was 48% (16/23) including 12% (4/33) complete remissions. Eight patients had minor responses or no change and 9 had progressive disease. Five of six patients with locally advanced and non-resectable disease had an objective response (1 CR, 4 PR's). The response rate in patients with metastatic disease was 41% (11/27). After a median observation time of 6.5 months, the median survival time was 10.5 months, with a median remission (CR + PR) duration of 8 months. Toxicity was manageable and included mild to moderate myelosuppression and gastrointestinal toxicities. One episode of life-threatening (Grade IV) leukopenia, and two episodes of severe diarrhea requiring hydration were noted. No treatment related death occurred. ELF is an effective combination in advanced gastric cancer and can be safely administered to elderly patients and patients with cardiac risk.

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.

Many patients with advanced gastric cancer cannot be treated with intensive chemotherapy. In an attempt to provide a feasible regimen for such patients, the combination of etoposide, leucovorin and fluorouracil (ELF) has been developed with promising results. The present study involved 42 patients with advanced gastric cancer who where unsuitable for cisplatin- or anthracycline-containing regimens because of their age (24 patients over 65 years), poor performance status (12) or the presence of concomitant illness (6). The treatment consisted of etoposide 120 mg/m2 i.v., 1-leucovorin 150 mg/m2 i.v. and fluorouracil 500 mg/m2 i.v. for 3 consecutive days every 3 weeks. Among the 41 evaluable patients, there was a 32% objective response rate (95% confidence interval 19-48%), with 7% of complete remissions. The median response duration was 4 months, the median time to progression in all patients was 5 months and the median overall survival was 10 months. No drug-related deaths or WHO grade 4 side effects were observed. On the basis of these results, we concluded that the ELF regimen is feasible and that its activity warrants randomized studies comparing the ELF combination with fluorouracil plus folinic acid.

Eleven patients with chemotherapeutically pretreated advanced gastric cancer were treated in a phase II study with a combination of 5-fluorouracil (5-FU) and Leucovorin (LV, folinic acid). 5-FU (1,200 mg/m2) and LV (100 mg/m2) were given as a parallel continuous intravenous infusion over 48 h every 2 weeks for at least 8 weeks. Toxicity and response rates were evaluated. Results show that this chemotherapeutic regimen is well tolerable, without any side effects exceeding WHO grade 1 toxicity, but that it has no considerable effects on tumor growth. None of the patients achieved disease remission. In 8 out of the 11 study patients therapy had to be discontinued prematurely because of disease progression. Therefore we conclude that the studied protocol of 5-FU/LV as second-line treatment of advanced gastric cancer although well tolerable is not effective.

In our previous randomized trial of advanced gastric cancer patients, the addition of epirubicin (EPI) to 5-fluorouracil (FU) with folinic acid (FA) resulted in an improved response rate and survival in the responder patients. Preclinical studies also showed an enhancement of FU and anthracyclines with interferon. To evaluate the possibility of human lymphoblastoid interferon (IFN) to enhance the therapeutic activity of the FA-FU + EPI combination regimen, 39 advanced gastric cancer patients received: FU at 375 mg/m2 i.v. immediately after FA (l-isomer form) at 100 mg/m2 i.v. for 5 consecutive days; EPI at 60 mg/m2 i.v. on day 1, and IFN 3 MU s.c. for 7 consecutive days, starting 2 days before the FA-FU administration. Thirty-seven patients were evaluable for response and toxicity. Twelve partial responses were observed with an overall response rate of 32% (95% CI, 17-48%). The median response duration was 6 months, and the median survival time was 8 months. Toxicity was mild and no grade 4 side effects or treatment-related deaths were observed. However, the addition of IFN to the FA-FU + EPI regimen did not improve response, duration of response or survival.

The combination of sequential high dose methotrexate and 5-fluorouracil (FU) combined with epirubicin (FEMTX regimen) has shown some clinical efficiency as a first line therapy in advanced gastric cancer. We evaluated the therapeutic activity of this combination in advanced colorectal cancer patients who failed the FU + folinic acid regimen, and in advanced gastrointestinal cancer situation where no standard regimen is available. Twelve patients with measurable metastatic colorectal cancer refractory to first line (n = 6) or second line (n = 6) chemotherapy, as well as 9 patients with advanced gastrointestinal cancer, entered this pragmatic pilot study. Eighty-six per cent and 38% of the patients experienced severe haematological or non-haematological toxicities, respectively. Four patients were not evaluable for response due to their early departure from the scheme due to acute toxic events (n = 3) or toxic death (n = 1). No objective response was observed, but 9 stabilisations and 8 progressive diseases were noted. The FEMTX regimen is not of clinical value as a salvage therapy in colorectal and gastrointestinal cancer, because of its toxicity and its lack of efficacy.

Etoposide, leucovorin and 5-fluorouracil (ELF) chemotherapy has been reported to be less toxic yet effective (response rates of 50%) in patients with advanced gastric cancer. A phase II study of ELF in 25 patients (11 males, 14 females, median age 53 years) with advanced adenocarcinoma of the stomach is reported. Patients received outpatient intravenous etoposide 120mg/m2 over 2 hours, folinic acid 300 mg/m2 over 2 hours, 5-fluorouracil 500 mg/m2 boluses daily for 3 days every 21 days. Of 17 measurable patients, there was one complete response (CR), 4 partial responses (PR) for a total response rate of 29.4%. Non-hematologic toxicity was modest (grade 0 vomiting 11/21, stomatitis 16/21, diarrhea 17/21). Grade 3/4 neutropenia was seen in 14/23, thrombocytopenia in 2/23, anemia in 5/23 patients. Median progression-free and overall survival was 4.1 and 7.1 months, respectively. In conclusion, ELF chemotherapy shows only modest activity in patients with advanced gastric cancer and is associated with severe hematologic toxicity.
