As long as the aetiology of acute lymphatic leukaemia of children is not known its therapy is based on clinical experience. Among the values of experience those factors will play a part, the evidence of which during the ALL initial stage will be a risk for successful therapy and survival rate. This results in a choice of more aggressive variants of modern therapy schemes. In a cytogenetic study made in 35 children with ALL it was tested, whether even leukaemic chromosome clones will be a risk for the course of acute leukaemia. The duration of the first remission and survival rate were considered as criteria. The evidence of a leukaemic chromosome clone could be shown to be followed by a short survival rate, irrespective of the stage of the disease where the clone had been observed first. Thus, cytostatic therapy in those ALL patients who are affected with luekaemic chromosome aberration of stem line character should be aimed at the complete annihilation of the clone, irrespective of other remission criteria. The failure of blood and bone-marrow cultures as early as during the untreated initial stage indicated a primary cellular immuno-insufficiency. This combination of cell immuno-depression with high peripheral leukocytes connts and a primary mediastinal tumour or a generalizing lymphosarcoma respectively, was the highest risk up till now for the course of the disease. Judging from the duration of the first remission and the survival rates, the consecutive schemes of therapy did not differ in their effect on leukaemia with pathological stem lines. On the basis of the present study the impression could not be excluded that up till now long term survival rates could be attributed rather to individual manners of response than to the modern therapy scheme.

A 4 7/12-year-old Caucasian female with a history of "croup-like symptoms" and persistent airway obstruction, was found to have a primary lymphosarcoma by biopsy at the time of laryngoscopy and bronchoscopy. No metastatic disease was found. After an induction course of vincristine, prednisone and local irradiation, she received CNS prophylaxis with intrathecal methotrexate and cranial irradiation. Maintenance therapy, administered over a 2 3/4 year period, consisted of cyclophosphamide, methotrexate, and 6-mercaptopurine. Excluding the diagnostic evaluation, she was hospitalized only once for the management of suspected sepsis, gastrointestinal ulceration and severe bone marrow depression. Since discontinuing treatment 27 months ago, she has remained free of disease.

Thirty patients with stage III and IV non-Hodgkin's lymphoma were treated by total-body irradiation (TBI). Eleven patients had previously received local radiotherapy or chemotherapy. Toxicity was confined to haematological depression. Complete remission of disease was achieved in 14 patients. Non-leukaemic patients who had received no previous treatment reacted best to TBI (ten complete remissions in 13 patients). We consider TBI a helpful treatment in non-leukaemic patients with advanced lymphosarcoma.

The effect of serum from 12 cats with lymphosarcoma induced by feline leukemia virus (FeLV) on the response of normal cat peripheral blood lymphocytes to phytomitogen-induced blastogenesis was studied. The majority of FeLV sera, when tested at a concentration of 20% of the incubation medium, caused a 40 to 70% reduction in the mean blastogenic response to concanavalin A compared to the response obtained with a similar concentration of normal feline serum. Results with pokeweed mitogen were similar, but the depression in blastogenesis was less than with concanavalin A. Further studies showed that the blastogenic inhibitory activity of FeLV serum (a) was heat labile at 56 degrees for 30 min, (b) could not be overcome by greater concentrations of mitogens, (c) was proportional to the concentration of FeLV serum in the incubation medium, and (d) could not be demonstrated when lymphocytes were preincubated in FeLV serum followed by washing and reincubating in normal feline serum. The results suggested that a substance present in the serum of FeLV-infected cats contributes to altered immunological reactivity during leukemogenesis in the cat.

An 8 to 10-week-old female New Zealand white rabbit, Oryctolagus cuniculus, which exhibited clinical signs of anorexia, depression, and torticollis was found to have lymphosarcoma with lymphoblastic leukemia. The multiple visceral involvement with neoplastic lymphoid cells observed in this animal was similar to previously reprted cases of lymphosarcoma in the rabbit. An unusual finding was the occurrence of lymphoblastic leukemia since lymphosarcoma in the rabbit has previously been reported as aleukemic.

The reactivity of peripheral blood lymphocytes from patients with advanced malignancy was assessed by mitogen-induced stimulation of protein synthesis as measured by 3H-leucine incorporation. It was confirmed that the lymphocyte response of patients was depressed. Furthermore, the lymphocytes of 15 out of 27 cancer patients, selected because of their low responses, inhibited the reactivity of normal lymphocytes in co-cultures. The lymphocytes from one patient with Hodgkin's disease were also inhibitory. In contrast, lymphocytes from healthy subjects, patients with chronic lymphocytic leukaemia, lymphosarcoma or multiple myeloma caused no suppression. Experiments with purified cell populations from patients with carcinoma indicated that purified T cells responded to mitogens while unseparated lymphocytes failed to respond and that the inhibitory activity was due to adherent cells, presumably monocytes. There was no evidence for B-cell-mediated suppression. However, in two cases inhibition was caused by isolated T cells of the patients and not by adherent cells. These experiments suggested that one mechanism for the depression of cell-mediated immunity seen in patients with advanced cancer may be the nonspecific suppresssion of certain T-cell functions by circulating monocytes.

Rostral and middle cranial fossa tumors affecting the optic chiasm and resulting in acute visual deficits were diagnosed in 7 dogs and 1 cat. Blindness and dilated nonresponsive pupils were the primary signs in all animals. Other concurrent neurologic deficits were either absent or were equivocal. Behavioral changes, including signs of depression and lethargy, were noticed in 1 dog and the cat subsequent to the onset of blindness. Retinal function was assessed as normal by electroretinography in all animals. The histologic necropsy diagnosis was pituitary carcinoma in 1 dog and the cat and paranasal sinus carcinoma with intracranial extension in 1 dog. A cytologic diagnosis of polycentric lymphosarcoma affecting the optic chiasm was diagnosed in 1 dog. In the remaining 4 dogs, results of computed tomographic imaging or endocrine function testing suggested pituitary gland neoplasia. Four dogs were treated with cobalt-60 radiation or chemotherapy. There was partial return of visual function in only 1 of the dogs treated with radiation.

Five cases of carcinoma and one case of lymphosarcoma of the pancreas in cats are reported. Duration of clinical signs ranged between three days and ten weeks, the mean age was 10.2 years. Anorexia, depression, and cachexia were the mean symptoms, in four animals a palpable mass in the cranial abdomen was noted. Laboratory evaluation was unspecific, in all cases diagnosis was performed by necropsy. Further diagnostical and therapeutical possibilities are discussed critically.

This paper reports the treatment results of cisplatin in 43 cases of malignant lymphoma. All were proved by pathology, cytology or X-ray and were non-resectable, disseminated advanced or refractory to routine anticancer drugs. The total dose of each course of cisplatin was usually 100-150 mg (2 mg/kg). One fifth or a tenth part of the dose was given with normal saline intravenously once a day. Complete remission rate was 9%, partial remission rate was 28%. Lymphosarcoma and reticulum cell sarcoma gave better results. During the treatment, anorexia, nausea and vomiting were common. Mild or moderate reduction of WBC and platelet was usually observed in the partial responsive cases but the depression on the bone marrow was relative mild. Cisplatin therapy did not cause marked renal dysfunction which was probably due to the hydration instituted. The anticancer action of cisplatin is similar to that of the alkylating agents but the participation of immunologic mechanism may also play a role.

Administration of either Escherichia coli asparaginase or guinea pig serum to C3H/HE mice with the 6C3HED lymphosarcoma is followed by depression of glycine in the tumor. This decrease in cellular glycine concentration does not occur in a tumor resistant to asparaginase. The inhibition of the lymphosarcoma by asparaginase can be reversed by intraperitoneal injection of asparagine or glycine. This reversal appears to be specific because lysine, threonine, serine, and aspartic acid were ineffective. Loss of cellular glycine may be more important than loss of asparagine because of the requirement for glycine in purine synthesis.
