Tumour necrosis factor (TNF) is a pleiotropic cytokine with activities that extend beyond its antitumour effect. There is now increasing evidence that TNF can be either constitutively produced or induced in human tumours. Tumour cells may also lead to TNF induction in normal cells. Experimental studies implicate TNF in processes that contribute to cancer progression. These range from stimulation of cancer growth and metastasis, to metabolic and haematological disturbances, e.g. cancer cachexia, anaemia, and hypercalcaemia. Future cancer therapies may therefore involve neutralisation of TNF activity in cancer patients.

The peripheral blood hematological and biochemical parameters in 60 patients with marrow involvement with carcinoma are described. In all patients the hematologic findings were of anemia (46%), thrombocytopenia (36%), leukocytosis (28%) and leukoerythroblastosis (22%). Elevated serum lactate dehydrogenase (sLDH) and alkaline phosphatase (sALP) occurred in 78% of patients and hypercalcemia in 28% and these abnormal biochemical parameters occurred more frequently with marrow fibrosis. In patients with small cell carcinoma of lung (SCCL) the sLDH was normal in 24% and sALP in 32% and abnormal hematological findings or a raised sLDH occurred more frequently with liver involvement. Bone scan was positive in 49% of patients and the hematological and biochemical parameters in these patients were similar to those of patients with a normal scan. Ten percent of patients with SCCL and marrow involvement had both a normal sLDH and bone scan.

It is generally accepted that some patients affected by mild asymptomatic primary hyperparathyroidism need not be treated with surgery, but may be medically managed without risk. However, our experience regarding 5 of these cases observed in the last two years, suggests a different approach. These patients, initially diagnosed as having mild hyperparathyroidism based on only moderately elevated serum concentrations of calcium and followed medically for years, were referred to us for a sudden worsening of their clinical course. One 35-year-old man presented hemorrhagic gastritis with severe anemia and type II AV block with syncopal attacks. Three women, aged 51, 64 and 65 years, presented with severe hypercalcemia associated with renal failure in two and with marked bone disease in another. In all these cases parathyroid neoplasms were preoperatively localized (by ultrasonography, CT scan and radioactive 201-Tl 99-Tc scan) and surgically removed. Histological examination showed a parathyroid carcinoma in the male patient and single gland enlargements in the three females. A fifth patient, a 65-year-old woman, was referred to us in critical condition: severe hypercalcemia, osteopenia with femur fracture, myocardial infarction and renal failure. She died in a few days, in spite of intensive medical care. These cases suggest that patients with hyperparathyroidism initially diagnosed as "mild" need close medical observation and preferably, in our opinion, should undergo surgery.

We compared the presentation features of three series of patients with multiple myeloma diagnosed between 1960 and 1971 (Kyle R, Mayo Clin Proc, 1975, 50, 29, n = 869), 1972 and 1986 (Clinica Medica, University of Pavia, n = 345) and 1987 and 1990 (Cooperative Group for Study and Treatment of Multiple Myeloma, n = 341). In the most recently diagnosed patients, the percentage of those who had symptoms related to multiple myeloma (i.e. any of bone pain, systemic symptoms, disturbances related to hypercalcemia, neurological involvement and hyperviscosity) was reduced (90 vs. 86 vs. 66%) (P less than 0.001), while the percentage of asymptomatic patients diagnosed by chance was increased (not reported, and 14 vs. 34%). In the most recent series, a lower percentage of spontaneous bone pain (68 vs. 60 vs. 37%, P less than 0.001) paralleled a lower incidence of advanced bone disease (osteolyses and pathological fractures, 60 vs. 64 vs. 34%), and renal failure (serum creatinine greater than 1.2 mg/dl) was also less common (56 vs. 44 vs. 33%, P less than 0.01), at least partially due to a decreased incidence of both hypercalcemia (30 vs. 20 vs. 18%, P less than 0.001) and of hyperuricemia (serum uric acid greater than 7 mg/dl, 47 vs. 32 vs. 26%, P less than 0.01). Systemic symptoms (weakness, infections, fever or weight loss) were reported more seldom by recently diagnosed patients, due to a decreased frequency of anaemia (haemoglobin less than 12 g/dl), leukopenia and thrombocytopenia, as well as of the systemic effects of bone pain and of renal insufficiency. These data indicate that multiple myeloma is diagnosed earlier now than in the past, and this must be taken into account when comparing survival data in treated series.

The authors report a case, perhaps the first, of immunoglobulin D (IgD) benign monoclonal gammopathy. The patient, a 48-year-old black woman, initially had a 500 mg/dl IgD-lambda M-spike, hypercalcemia, and anemia. There was no bone pain, lytic bone lesions, or evidence of renal failure. The bone marrow showed 2.8% plasma cells with a diffuse (not nodular) IgD plasmacytosis and strong lambda predominance. Only trace amounts of free lambda light chains could be demonstrated by immunoelectrophoresis in serum and concentrated urine. The anemia responded quickly to iron therapy. Chemotherapy was not initiated. Over the 6+ years of follow-up, the patient has had no progression of clinical disease attributable to her IgD monoclonal gammopathy. The IgD M-spike has steadily decreased.

A 34-year-old male was admitted to our hospital because of anorexia and nausea in September, 1987. On admission, anemia, thrombocytopenia and hypercalcemia were observed, and the peripheral blood showed leukocytosis with atypical plasma cells (50%). Bone marrow aspiration showed hypercellularity, with a presence of atypical plasma cells (82%). The M-type protein in the serum and urine was identified as lambda Bence Jones protein by immunoelectrophoresis. On systemic skeletal X-rays, osteolytic lesions were not detected. Thus, a diagnosis of plasma cell leukemia associated with hypercalcemia was made. Hypercalcemia was treated successfully with overhydration. However the disease was refractory to combination chemotherapy, and at 10 months after diagnosis, he died of septic candidiasis. Hypercalcemia associated with plasma cell leukemia in its initial stage is rare.

Twenty-five Chinese patients with human T-cell lymphotropic virus type I (HTLV-I) associated adult T-cell leukaemia/lymphoma (ATLL) were identified in Taiwan. No patients had been outside Taiwan and none were descendants of Japanese heritage. Their ages ranged from 28 to 71 years. There were 17 men and eight women. Main clinical and laboratory features at presentation were lymphadenopathy (16), skin lesions (11), hepatosplenomegaly (11), pulmonary lesions (11), hypercalcaemia (10) and bone marrow infiltration (14). Peripheral blood was characterized by leucocytosis with presence of pleomorphic abnormal lymphocytes but rare anaemia or thrombocytopenia. The clinical subtypes were acute in 15, chronic in three, smouldering in one, and lymphoma type in six. The immunophenotypes of the ATLL cells were characterized by the expression of CD2+, CD4+, CD7-, CD8- and CD25+. The overall prognosis was poor with a median survival of 5 months. The acute form had a significantly shorter survival (2 months) than lymphoma type (13 months). Susceptibility to various infections was common. Pulmonary complications accounted for 73% of the causes of death. The clinicopathologic features of ATLL in Taiwan are indistinguishable from those in HTLV-I endemic areas. The present series adds to the knowledge of the worldwide pattern of the disease.

Congenital hypothyroid dwarfism was diagnosed in a family of Giant Schnauzers. Three female and two male puppies from different litters were evaluated for dwarfism, lethargy, somnolence, gait abnormalities, and constipation. On physical examination, disproportionate dwarfism (n = 5), macroglossia (n = 3), hypothermia (n = 3), delayed dental eruption (n = 3), ataxia (n = 2), and abdominal distension (n = 1) were identified. Results of initial laboratory tests showed anemia (n = 4), hypercholesterolemia (n = 4), hypercalcemia (n = 2), and transudative abdominal effusion (n = 1). Radiographic skeletal surveys disclosed epiphyseal dysgenesis and delayed skeletal maturation (n = 5). A diagnosis of hypothyroidism was established on the basis of low basal serum thyroxine concentrations that failed to increase following the administration of TSH (n = 5) and markedly reduced to absent thyroid image when evaluated with gamma camera imaging of the thyroid gland (n = 4). In the two dogs that were most thoroughly evaluated, the results of thyroid histology, prolonged TSH testing, and repeat thyroid imaging, after three daily injections of TSH, were all consistent with secondary or tertiary, rather than primary, hypothyroidism. When TSH was administered over a period of 3 consecutive days (5 IU/day, subcutaneously), serum thyroid hormone response became normal and resulted in a normal thyroid image in the two dogs re-evaluated with gamma camera imaging. Daily treatment with oral levothyroxine (20 micrograms/kg) resulted in complete remission in puppies (n = 4) treated prior to 4 months of age. The other puppy failed to attain normal breed standards for height.(ABSTRACT TRUNCATED AT 250 WORDS)

A variety of side effects have been reported with the use of interleukin-2 alone or in combination with lymphokine-activated killer cells in patients with disseminated neoplasms. The present study was undertaken to determine the effects of high-dose interleukin-2 administration in normal rats. Sprague-Dawley rats were treated with intravenous recombinant interleukin-2 (900,000 IU/kg/day) for 9 consecutive days. Animals were placed in individual metabolic cages, and arterial blood pressure, food intake, body weight, and urine output were monitored. On day 10, animals were killed by exsanguination, various tissues were harvested, and a variety of hematologic and chemical assays were performed. The results were compared with those of placebo-injected normal control and pair-fed groups. The interleukin-2-treated group exhibited anorexia, weight loss, hypotension, anemia, leukocytosis, lymphocytosis, eosinophilia, hypercalcemia, azotemia, and a marked urinary concentration defect. Histologic examination of various tissues revealed widespread infiltration with mono-nuclear cells and eosinophils in most organs, especially in the lungs and liver of interleukin-2-treated animals. Other abnormalities included severe panlobular hepatitis, hepatocellular necrosis, and thymic involution. Renal involvement was mild and consisted of focal interstitial infiltration by mononuclear cells. According to these observations, administration of high-dose interleukin-2 in normal rats results in a score of significant functional, biochemical, and histologic abnormalities.

The performed clinical analysis covered 80 patients with multiple myeloma, treated at Hematological Clinic of PMA in the years from 1974 to 1984. The following prognostic factors were analyzed: age, sex, living place, clinical advancement period of the disease, functional state according to Karnofsky (Karnofsky's index), monoclonal protein type, the concentration of urea, creatinine, calcium in blood serum, hemoglobin concentration as well as the neoplastic tumour mass. These factors were considered to indicate poor prognosis: severe anemia, hypercalcemia, renal failure, and Karnofsky's index being below 70 points.
