Pyrazofurin was administered to 21 patients with solid tumors at a dose of 200 mg/m2 iv weekly, because this dose had been shown to be well-tolerated and pharmacologic effects of a single dose at this level persisted for up to 7 days. An anemia consistent with a disturbance in rbc production was seen in most patients. Other toxic effects included stomatitis, rash, and myelosuppression. No complete or partial responses were noted, but two patients with alveolar cell carcinoma of the lung each had stable disease for 12 months. Most of the patients in this study tolerated the weekly dosage schedule well with only minimal myelosuppression, suggesting that this agent and schedule might be acceptable for use in combination chemotherapy. Several theoretic reasons favor the use of pyrazofurin in this manner. Pyrazofurin should also be evaluated more fully in patients with polycythemia vera, mycosis fungoides, and psoriasis, since other orotidylate decarboxylase inhibitors have been shown to be effective in these diseases.

The types of anemia associated with natural and experimental feline leukemia virus (FeLV) infection in cats were investigated. In one experiment, 10 kittens were inoculated neonatally with Jarrett FeLV-1, an isolate of subgroup A; 6 developed anemia a few weeks later. This anemia was characterized by macrocytosis, normoblastosis, increased erythropoiesis in the bone marrow, and extramedullary hematopoiesis in the spleen. Anemia was transient and nonfatal and occurred before the onset of lympoid malignancy. The same type of anemia was also seen in 9 of 24 kittens inoculated with Jarrett FeLV-9 of subgroups A and B. A different form of anemai occurred in another experiment in which 10 kittens were inoculated with FeLV-C of subgroup C only. All 10 kittens developed a profound aplastic or erythroblastopenic anemia in which the bone marrow became depleted of erythroid tissue; all kittens died within 16 weeks, most as a direct result of anemia. In an experiment in which kittens were inoculated with FeLV-B of subgroup B only, no kitten showed anemia. Cats with naturally acquired, nonleukemic lymphosarcoma were also studied. Of 33 lymphosarcomas in which myelophthisis was excluded as a cause, 54% of the affected cats had anemia, the features of which were consistent with hemolytic origin. When virus could be grown from these lymphosarcomas, it was of subgroup A alone or a combination of A and B. With one exception, anemic cats had low or negative titers to feline oncornavirus-associated cell membrane antigens. Until more isolates have been tested, it is not known if the various hematologic changes reflected differences in the pathogenic effects of the subgroups of the virus or of types of strains within them.

Malignant mixed tumor of the liver seen in a 4 year old girl was reported. Progressive hepatomegaly, jaundice, anemia, and extraordinarily high level of serum total cholesterol were noted clinically. Postmortem examination had disclosed that most part of the tumor was occupied by fibrosarcomatous cell growth admixed with rhabdomyosarcomatous component. In addition, carcinomatous component was distinctly recognized in a restricted part of the liver tumor. Previous reports on malignant mixed tumor of the liver were reviewed and it was emphasized that the histological diagnosis of malignant hepatic mixed tumor must be cautiously followed Edmondson's criteria; which requires existence of both epithelial and mesenchymal components of neoplastic nature and malignancy of either or both components in a hepatic tumor.

The clinical and pathological findings in 200 consecutive cases of colorectal carcinoma treated by surgical resection have been recorded and subjected to computer analysis. This is the initial report from a long-term prospective survey of this disease. The two most frequent presenting symptoms were altered bowel habit (51.5%) and bleeding (49.5%). Symptoms due to anaemia occurred in 16% of cases and acute obstruction in 13.5% of cases. The value of the various investigations in establishing the diagnosis is discusses. At the time of resection the disease had already reached an advanced stage in a majority of the patients. In 26% of cases it was known that complete resection of tumour tissue had not been achieved. A direct relationship between stage of spread and histological grade of malignancy was noted. The incidence of advanced stage, high histological grade and mucinous tumours was greatest in the right side of the colon. A study of early carcinomas has confirmed that many have arisen from benign epithelial neoplastic polyps. The significance of these observations is discussed.

Under observation were 140 children with retroperitoneal neurogenic tumors. In 69 of 125 patients with malignant neoplasms metastases were detected. Hemographic and myelographic findings were analysed depending on the degree of malignancy and tumor spread. Anemia usually moderate and normochromatic was observed only in neuroblastomas. This group of patients is also characterized by frequent shifts to the left leucograms and high sedimentation test, contrary to benigh tumors. The investigation of bone marrow allows one to reveal the suppression, and more rarely irritation of various blood stems.

Sixty-seven specific-pathogen-free cats of various ages (newborn, 2 wk, 1 mo, 2 mo, 4 mo, and 1 yr) were inoculated ip with either the Rickard (R) or the Kawakami-Theilen (KT) strain of feline leukemia virus (FeLV). Susceptibility to FeLV was judged by induction of a) FeLV group-specific antigens (gsa) in leukocytes, b) FeLV-related disease, c) antibody to feline oncornavirus-associated cell membrane antigen (FOCMA), and d) virus-neutralizing (VN) antibody. Susceptibility to FeLV-decreased with age. Persistent viremia and FeLV-related disease developed in 100% of cats inoculated as newborns, in 85% of cats inoculated at 2 weeks to 2 months of age, and in 15% of cats inoculated at 4 months or 1 year of age. Cats susceptible to FeLV leukemogenesis became persistently FeLV gsa-positive (viremic) at 4 weeks post inoculation and thereafter and produced little or no FOCMA or VN antibody. Cats that resisted leukemogenesis by FeLV all developed persistent FOCMA and VN titers and never became FeLV gsa-positive. The disease in inoculated cats was influenced by virus strain; FeLV-R induced predominantly thymic lymphosarcoma, whereas FeLV-KT caused fatal nonregenerative anemia without concurrent neoplasia.

We investigated the reliability of the fixed cell indirect fluorescent antibody (IFA) peripheral blood smear test as an index of systemic infection with FeLV. Positive results with this test were found to correlate well with detectable FeLV p30 antigen in bone-marrow smears by IFA, in serum and tissue by competition immunoassays, and with type-C particles in bone marrow or spleen by electron microscopy. Most cats with lymphoma, anemia or infectious peritonitis were positive for FeLV and showed a poor or absent antibody response to FeLV p30, gp70, and FOCMA antigens. Most older cats with lymphoma, carcinoma, or sarcoma were negative for FeLV expression and also lacked these FeLV-related antibodies. Detectable immunologic response to FeLV p30 and gp70 proteins and a high-titered FOCMA antibody response were generally restricted to certain healthy cats exposed to FeLV. Antibody to endogenous RD-114 viral p30 and gp70 was not detected in any of a large number of feline sera tested. The prevalence of FeLV-related diseases and immunologic responses to FeLV in healthy cats was directly correlated with the degree of FeLV exposure. By using the IFA blood smear and FOCMA antibody tests one can monitor the horizontal spread of FeLV in multi-cat household and accurately predict the FeLV disease susceptibilty or resistance of individual cats in each environments.

We characterized several aspects of spontaneous regression of lymphocytic leukemia in mice. The disease, induced by the helper murine leukemia virus (MuLV) component obtained from the regressing Friend virus complex (RFV), was characterized by spleen and lymph node enlargement, thymus involvement, and anemia. Leukemia regression occurred in about 25% of infected mice and resulted in the return of lymphoid organs to near-normal weight and normal histology and the recovery from anemia. A tenfold to 1,000-fold decrease in virus titer was seen in those mice in which leukemia regressed when compared to leukemic animals, although infectious virus was still recoverable from apparently normal spleens. The sera of mice in which leukemia regressed contained potent virus-neutralizing activity that was associated mainly with immunoglobulins. These studies firmly supported the evidence that the regressing phenotype of RFV was due to its helper MuLV component (MuLV-RF).

Biochemical and immunological investigations were made on the nature of fluorocarbon-treated antigens obtained from placenta and cancer tissues. 1) By the diffusion in gel method, a specific antigen common to cancer tissues was found in placental tissue, but not in normal tissue. Immunoelectrophoretically, a characteristic precipitate line was found in alpha2-globulin region. 2) Further purification of the placental antigens was carried out by DEAE-cellulose chromatography. Four fractions positive to Folin reaction were detected. 3) Immunoelectrophoresis revealed that the active component was concentrated in a fraction eluted with 0.1 M NaCl in 0.05 M phosphate buffer, pH 5.8 (5.8-fraction). 4) Further purification of the active component was performed by using polyacrylamide gel electrophoresis. Chemical analysis indicated that it belonged to glycoprotein. 5) This substance did not induce anemia in rabbits and had no influence on the osmotic fragility of erythrocytes. These results indicate that this substance is different from the anemia-inducing substance which was previously reported by us.

Three of nine children of possibly consanguineous American Indian parents developed typical osteosarcoma in a 2-year period. Etiologic investigations detected limb anomalies and elevated mean corpuscular volumes (98--109 micrometer3) in the surviving tumor patient, several of her sibs, and her father. Limb anomalies included simple clinodactyly with brachymesophalangy, absence of one digital ray of the foot, and bilateral radioulnar synostosis. The red cell macrocytosis was not accompanied by anemia or explained by the usual causes. No unusual environmental exposures were found and screening for possible oncogenic viruses by culture, electron microscopy, and serology was negative. All family members had elevated antibody titers to Epstein-Barr viral antigens. The proband and her father had excessive chromosomal breaks in the bone marrow. This unusual familial pattern of osseous malignancy and malformation and defective erythropoiesis, tentatively called OSLAM syndrome, may represent impaired regulation of bone development.
