RESUMEN
We performed combination chemotherapy adapted to chronotherapy with 5-fluorouracil, leucovorin, mitomycin C and cisplatin in 11 patients with gastric cancer and 7 with colorectal cancer. Treatment consisted of a 5-day course of continuous arterial or intravenous infusion of 5-FU (500 mg/body/day), arterial or intravenous infusion of leucovorin (20 mg/body/day) at 6:00 p.m. on days 1-5, arterial or intravenous infusion of mitomycin C (2 mg/body) at 9:00 a. m. on day 5, and arterial or intravenous infusion of cisplatin (20-80 mg/body) at 6:00 p.m. on day 5. The effective rate against gastric cancer was 73%; however, the effective rate against colorectal cancer was 29%. During and after this therapy, there was only a little appetite loss, nausea and stomatitis.

Combination chemotherapy with multiple drugs (FLMP therapy), in which the drugs were determined based on biochemical modulation and the dosing schedule was established in accordance with the circadian rhythms of the human body, was performed in cases of advanced recurrent gastric cancer. The drugs were administered according to the following schedule: 500 mg of 5-FU (continuous) on days 1-5 (the dose was increased during the night), 20 mg of LV on days 1-5 (at 6 PM), 2 mg of MMC on day 5 (at 9 AM) and 60-80 mg of CDDP on day 5 (at 6 PM). A five-day course was administered by intravenous drip or hepatic arterial infusion at intervals of 4 weeks. Of 14 patients treated, the effect was estimated to be CR in 3, PR in 6, NC in 3, and PD in 2. The effectiveness rate was 62.3% overall, and the rate by administration route was 6/10 (60.0%) for i.v. and 3/4 (75.0%) for i.a. The side effects were slight. Those of grade 3 or more included anorexia in 5%, nausea and vomiting in 1%, stomatitis in 1% and leukopenia in 1%. This therapy, administered in accordance with the theory of chronotherapy, caused few side effects, and thus is considered a promising treatment for gastric cancer.

A 64-year-old man underwent total gastrectomy and placement of the hepatic arterial catheter for advanced gastric cancer with multiple liver metastasis. After the operation, repeated hepatic arterial infusion chemotherapy was performed. Treatment consisted of a 5-day course of continuous arterial infusion of 5-FU. (500 mg/body), leucovorin (21 mg/body) intravenous infusion at 4:00 p.m. on days 1-5, mitomycin C (2 mg/body) arterial infusion at 9:00 a.m. on day 5, and cisplatin (40 mg/body) arterial infusion at 4:00 p.m. on day 5. A total of 13 courses of this chemotherapy diminished liver metastasis. During this therapy, the patient's condition was good, with no experience of nausea or leukopenia.

As a postoperative adjuvant chemotherapy for gastric cancer, we have administered a combination of NCS (Neocarzinostatin) and 5-FU (NF treatment method) and in this paper we have compiled the results obtained in patients who were treated for 5 years in an attempt to compare the 5-year survival rate with that of patients administered a combination of MMC and 5-FU (MF treatment group) and a control group administered no anticancer agents. As the selection of either NF or MF treatment was conducted on an annual basis, this study can be considered an historical controlled study. The results obtained are summarized as follows. On comparing the survival rate of the NF treatment group and the control group, the 5-year survival rate for all patients who underwent curative resection and all patients with histological stage III cancers and the curative resection PS (+) group, as well as the survival period of the non-resected patients, showed a statistically significant difference, indicating that the survival rate was higher in the NF group. On comparing the NF group and the MF group, although no statistically significant difference was observed between then based on a stratified analysis of all resected cases, histological stage differences and n.ps factors, etc., certain values tended to indicate a higher survival rate for the NF group. Moreover, the survival rate of the non-resected patients was more favorable in the NF group. These results confirm that NCS is useful for the treatment of stomach cancer and compares favorably with MMC. The appearance of side-effects was significantly lower in the NF group in comparison with the MF group and the number of patients who had to discontinue therapy was extremely low.
