The chemotherapeutic action of 5-fluorouracil monotherapy on HRS-Sarcoma in mice was compared with those of 5-fluorouracil nucleoside combinations (thymidine, cytidine or guanosine). The curative action of 5-fluorouracil was potentiated without increasing its toxicity, when cytidine or guanosine were applied at definite intervals before or after 5-fluorouracil.

The biological activity of a hot-water extract from delipidated BCG, designated as HSA (Hot-water Soluble Adjuvant), was investigated. The HSA did not induce hyperreactivity to bacterial endotoxin. The hot-water extract from which nucleic acids had been removed by streptomycin (SM-HSA) was found to enhance the delayed-type hypersensitivity as evidenced by the results of footpad reaction of mice. The HSA and SM-HSA could be injected to mice by an intraperitoneal route for 20 consecutive days without undesirable side effects. A comparative study was made on the effects of HSA in relation to the duration and doses of treatment with HSA using the ddI mice inoculated with Sarcoma-180. The most remarkable effect was observed when 0.25 mg of HSA had been injected for 20 consecutive days. Also SM-HSA was found to exert antitumor activity when applied in the same manner as above. These results suggest that the presence of nucleic acids is not related to the biological and antitumor activities of the hot-water extract.

Spin-lattice relaxation time measurements were made on the muscle, heart, kidneys, spleen, liver, brain and blood of both normal mice and those injected with Sarcoma-180. As well as a marked increase in the relaxation time of the tumour itself, mice injected with Sarcoma-180 showed a rise in the kidney relaxation time, along with blood relaxation times which were often either above or below the range found in normal mice. Correlation coefficients for the relaxation times of the various organs were calculated and found to be very sensitive to the physiological state of the animal. For healthy mice, the correlations were reasonably high, but even mild stress decreased the correlations, whilst the presence of cancer almost completely destroyed the correlations. These findings are all consistent with the hypothesis that cancer affects the water regulatory system of the animal as a whole.

Sarcoma 45 cells were inoculated subcutaneously to rats and carcinosarcoma. Walker 256 cells implanted intramuscularly in the Wistar rats. The injections of the heparin-urea complex with a simultaneous blocking of the vegetative nerves system created an anticoagulant and fibrinolytic background in the organism of these animals and produced an antitumorigenic effect, i.e. the inhibition of growth of primary tumors and metastases, the mitotic activity decline in the malignant tissue and a change in the submicroscopic structure of the sarcoma 45 cells (greater chromatin density, prevalence of the fibrillar component in the nuclei, swelling of the reticulum channels, condensation of mitochondria and reduction of polysomes). All this shows the physiological activity of malignant cells to decline through imitating the hyperfunction of the anticoagulation blood system.

N-Ethyloxycarbonylaminomehyl-L-isoleucine (A-145), a novel antitumor amino acid derivative, is an anti-tumor agent effect in cases of Ehrlich ascites rather than against Sarcoma-180. The chemotherapeutic index of A-145 was 14.9 for Ehrlich ascites carcinoma and 4.2 for ascites Sarcoma-180. Experimental studies on ddy mice regarding the difference in susceptibility of these two tumor cell lines to A-145 gave the following results. In in vivo experiments, the uptake of 14C-A-145 by Ehrlich ascites carcinoma was greater than by Sarcoma-180, i. e. the uptake ratio of Ehrlich ascites carcinoma/Sarcoma-180 was 1.52 at 30 min and 2.7 at 24 hr after injection. In in vivo experiments, there was no remarkable difference between Ehrlich ascites carcinoma and Sarcoma 180 in the subcellular distribution of 14C-A-145, and the majority of the radioactivity taken up was distributed in nuclei and cytosol fractions. In in vitro experiments, the uptake of 14C-A-145 by both cell lines was found to be temperature sensitive, glucose dependent, and decreased on addition of KCN, 2, 4-dinitrophenol or iodoacetic acid. In in vitro experiments, competitive inhibition by L-isoleucine on 14C-A-145 uptake into tumor cells was observed in both cell lines, however, in vitro experiments, the inhibitory effect of A-145 on cell growth in cultured Sarcoma-180 was not reversed by L-isoleucine.

Sarcoma metastatic to the central nervous system is generally considered to be rare. In this report three cases of sarcoma with metastasis to the central nervous system are presented. The case of rhabdomyosarcoma of the lung probably represents the first reported instance of such tumor metastatic to the central nervous system. The case of fibrosarcoma of the thigh is thought to be the first report of metastatic sarcoma with leptomeningeal dissemination. The metastatic brain lesions of the alveolar soft part sarcoma were incidental findings at autopsy. A summary of 22 cases previously reported and a brief discussion of the mode of metastasis of sarcoma, as compared to that of carcinoma, are also presented.

We studied the effect of thyroxine treatment on tumor growth and metastases resulting from tumor implants on the hind feet of mice in two syngeneic systems. In control, untreated A/Jax mice, tumor Sarcoma 1 at Day 14 after implantation had average tumor weight of 582 +/- 60 (S.D.) mg and showed an incidence of 57% metastases to regional popliteal nodes and 5% metastases to thymus. In contrast, the thyroxine-treated group (40 microgram/mouse s.c., 5 times/week for 1 month) had an average tumor weight of 808 +/- 56 mg (p less than 0.001), and metastases to popliteal nodes and thymus were 90 and 35%, respectively. In another syngeneic tumor system, Lewis fibrosarcoma was implanted in C57BL/6J mice, and the tumor weight and metastatic index (derived from the number and size of the pulmonary tumor foci) were determined at Day 28. Again, the synthetic L-thyroxine treated group showed a significant enhancement tumor growth and metastatic index. The mean tumor weight in the treated group was 385 +/- 26 mg (control, 694 +/- 25 mg; p less than 0.005) and metastatic index was 84 +/- 29 (control, 30 +/- 25; p less than 0.001). Induced hypothyroidism (treatment with 131I, 100 microCi/mouse i.p.) showed the reverse effect on both tumor systems. These results suggest that both tumor systems are dependent on thyroid hormones for their growth and spread.

The serum Zn content in rats bearing Yoshida-Sarcoma, AH 66F, AH 13 or AH 109A was found to be low as compared with that in normal controls. In the rats which had received intraperitoneal inoculum of Yoshida-Sarcoma, the effects of anticancer drugs were closely related to the changes in serum Zn content. Namely, serum Zn content increased and approached the normal range almost parallel with the prolongation of survival time by anticancer drugs. As the causes responsible for the reduction in quantity of serum Zn in the tumor-bearing rats, the reduction of serum albumin content and the accumulation of Zn in the tumor tissue and organs such as the liver and kidneys were suggested.

Anti-tumour activity of an aromatic retinoic acid analog has been tested on Sarcoma J in syngeneic system. Tumour complete regression rate and median survival time of progressors mice are significantly improved. These results are at variance with previous observations suggesting the lack of activity of this compound on transplanted murine tumours. Arguments in favour of an immunological stimulation responsible for the observed anti-tumour effect are presented and discussed.

Initial screening of the 2 recently developed immunosuppressive agents, cyclosporin A and cyclosporin C, in 11 murine transplantable neoplasms revealed significant increase of lifespan with long-term survivors after i.p. injection to the ascites tumors, Taper liver, Sarcoma 180J and Ehrlich.
