[Local administration of recombinant interferon-beta to patients with cancer-associated body cavity fluids].

The effects of local administration of interferon-beta produced by recombinant DNA technology (GKT-beta, Kyowa Hakko) on malignant effusion were studied in cancer patients and evaluated on the basis of the Criteria for the Evaluation of the Clinical Effects of Solid Cancer Chemotherapy (effects on malignant effusion). Out of 13 cases of peritoneal effusion, the effects were evaluated in 9 cases. Four of these cases remained free from ascites for 4 weeks and were evaluated as complete response (CR). Administration of GKT-beta alone was performed in 4 of 7 cases of pleural effusion, and CR was obtained in 1 case each of breast cancer, gastric cancer and malignant mesothelioma. In cases of gastric cancer, CR was obtained in 5 of 10 cases. The above results suggest that GKT-beta is a very effective drug against malignant effusion.

Primary malignant lymphoma of the breast. With a review of 73 cases among Japanese subjects.

We report a case of a 71-year-old female with primary malignant lymphoma of the breast. The patient noticed a lump in the right breast approximately six years prior to consultation to the Surgical Department because of a rapid growth of the lump, and had no other tumors noticed throughout the body during that period. Histology proved the case to be a "reticulum cell sarcoma" (large cell type) producing IgM in the tumor cells, instead of a breast carcinoma as clinically diagnosed. At the same time, a total of 73 cases of mammary malignant lymphoma among Japanese subjects were reviewed. The criteria for primary or secondary malignant lymphoma of the breast, and histological diagnosis and pathogenesis of the primary breast malignant lymphoma were discussed.

[Intralymphatic administration of BCG-CWS in advanced malignant melanoma].

BCG-CWS was administrated into lymphatic vessels in the treatment of advanced malignant melanoma metastasized to the lymph node of the posterior peritoneum. Side effects consisted of fever, lymphangitis, a decrease in urinary output and a slight rise in serum GOT, there being no serious side effects. Clinically, tumor mass in the abdomen cleared but metastases to the other organs increased, and the patient died of general dispersion of the disease. At autopsy, the abdominal mass became flat, with the cut surface of yellowish brown color. Histologically, this mass formed necrosis made up of destroyed tumor cells and histiocytes. BCG-CWS mediated histiocyte response appeared to destroy tumor cells. Thus, it is possible that local administration BCG-CWS could elicit a potent response even in advanced carcinoma. Since the contact of BCG-CWS with tumor cells produced this response, administration of BCG-CWS into the lymphatic vessels may be indicated where the lymph current to the metastasized lymph node is not obstructed. This treatment would be effective particularly in the case of micrometastasis, and there is a possibility that it could elicit a specific response.

Increased S(-)-apomorphine-induced vacuous chewing and attenuated effect of chronic haloperidol treatment in streptozotocin-induced diabetic rat.

The incidence of S(-)-apomorphine-induced vacuous chewing movements (VCMs) as a model for tardive dyskinesia was investigated in streptozotocin (STZ)-induced diabetic rats. A single dose of STZ (65 mg/kg, intravenously) caused a diabetic state (hyperglycemia, 480-490 vs. 116-118 mg/dl in naive rats). S(-)-apomorphine (250 micrograms/kg, subcutaneously)-induced VCMs were significantly intensified in diabetic rats which had received STZ 9 weeks previously. The enhancement of VCMs was also observed in nondiabetic rats which received subsequent treatment with depot haloperidol (4 mg/kg, intramuscularly, once a week, every week for 4 weeks) followed by a 2-week washout period. The ability of haloperidol to enhance VCMs was attenuated in diabetic rats. The implications of these results in relation to altered neurotransmissions in STZ-induced diabetes are discussed.
