[Combined antitumor therapy with polyamine biosynthesis inhibitors and mitomycin C].

A combined effect of the polyamine biosynthesis inhibitors, alpha-difluoromethylornithine (DFMO) and methyglyoxal-bis-guanylhydrazone (MGBG) with mitomycin C (MMC) was studied. DFMO, MGBG and MMC were given intraperitoneally to nude mice xenotransplanted human gastric cancer. This new combination of the three drugs resulted in the complete halt of the xenotransplanted tumor growth and marked decline of spermine levels in the tumor tissues. The other treatments with DFMO and MGBG as well as MMC alone were inferior to this new combined therapy in suppression in both tumor growth and tissue spermine level. These data suggest that this new combined treatment be effective against human gastric cancer.

[Immunologic studies on the patients with gastrointestinal cancer--with particular reference to correlation between T lymphocyte and macrophage].

Correlation of monocyte with T lymphocyte or IgG-FcR+ T lymphocyte was studied in 57 gastrointestinal cancer patients and 24 healthy volunteers as control. In 24 volunteers, no correlation was found between them. Forty gastrointestinal cancer patients with curative tumor showed pre-and postoperatively a close correlation between monocyte and T lymphocyte, but there was little correlation, both pre-and postoperatively, between monocyte and IgG-FcR+ T lymphocyte. Seventeen patients with recurrent and/or inoperable gastrointestinal cancer, had a reverse correlation of monocyte with IgG-Fc R+T lymphocyte. It was suggested from these data that mononuclear phagocyte system (monocyte), which fulfils its function as an antigen presentation, has an intimate relationship, both directly and indirectly, to T lymphocyte.

[Immunological study of the actions of auxiliary antitumor agents--effects on lymphocyte transformation reaction and natural cytotoxicity activity in nude mice].

P-aminobenzoic acid-N-xyloside (K-247) and dimethyl-2- (tetrahydro-2-furanyl) ethylsulfonium-p-toluene sulfonate (GT-101) were tested their in vivo effects on both mitogen-induced lymphoproliferative reactions and natural cell-mediated cytotoxicities in BALB/c nude mice (homozygous and heterozygous) spleen lymphocytes. The animals were injected i.p. either 400 mg/kg of K-247 or 5 mg/kg of GT-101 (for 7 days consecutively). GT-101 caused a positive increase in lymphoproliferations by PHA and SPA, while the administration of K-247 had no effect on PHA-and SPA-induced lymphoproliferations. Furthermore, in a 12-hour 51Cr release assay, both drugs had no effect on the natural cell-mediated cytotoxicity against YAC-1 cells.

Clinical outcome of intraoperative pelvic hyperthermochemotherapy for patients with Dukes' C rectal cancer.

In attempts to prevent local recurrence after curative resection for rectal cancer, intraoperative pelvic hyperthermochemotherapy (IOPHC) was prescribed for 27 patients with Dukes' C cancer. The procedures used were as follows: immediately after amputation or resection of the rectum with extended lymphadenectomy, the pelvic cavity was filled with physiological saline containing 40 micrograms/ml mitomycin C, which was warmed at 45 degrees C for 90 min with an apparatus devised for IOPHC. Thirty-five patients who underwent surgery alone for Dukes' C rectal cancer within the same period served as controls. There was a local recurrence in three patients in the IOPHC group (11.1%), and in 13 in the control group (37.1%). With regard to hepatic or pulmonary metastasis, there was no difference between the two groups. There was no morbidity in the IOPHC treatment except for a large volume of exudate from the pelvic cavity. Thus, IOPHC can be considered as one option for limiting local recurrence after surgical resection of an advanced rectal cancer.
