Three tumor cell subpopulation lines derived from a single, spontaneously occurring BALB/cfC3H mammary tumor were evaluated for their ability to cause a leukemoid effect in mice. One of the BALB/cfC3H tumor cell lines (410.4) produced leukocytosis with neutrophilia, hypercalcemia, and thymic atrophy. A second line (66) produced none of these effects. The third line (168) was intermediate in its ability to affect neutrophil counts and splenomegaly but did not produce thymic atrophy or hypercalcemia. These studies demonstrated that the hemopoietic effect of tumor cells derived from a single tumor was variable and that a tumor cell line which caused neutrophilia also induced hypercalcemia and thymic atrophy, the same association that was reported previously in the case of murine CE mammary carcinoma. These observations will be useful in the further investigation of pathophysiology of tumor-induced leukemoid reactions, hypercalcemia, and other paraneoplastic syndromes.

Two hundred patients with myeloma disease have been reported in Bulgarian medical literature for the period 1943-1973. The males are 62.3 per cent and the females--37.7 per cent. Out of all the cases 91.2 per cent are at the age of 40 and 48 per cent of the patients--between 51--60. The following incidence rate of the investigated syndromes and symptoms was established: osseous--96 per cent, asthenic-dynamic--93.2 per cent, consumptive--74,6 per cent, neurologic--57.4 per cent, febrility--53 per cent, hepatomegalia--50 per cent, splenomegaly--24.3 per cent, lymphoadenomegalia--23.5, per cent, hemorrhagic--37.1 per cent, skin manifestations--20.7 per cent, spontaneous fractures--42.7 per cent, osseous tumors--25 per cent, hypercalcemia--56.1 per cent, broachitis and bronchopneumonia--50.7 per cent of the patients. The distribution according to the X-ray criteria reveals: osteolytic form--81,4 per cent; diffuse-porotic--9.3 per cent and osteonegative--9.3 per cent. The diagnosis was made within 1 1/2 years after the appearance of the first manifestations. The average life span is about 2 years (2 1/2 months to 5 1/2 years). A difference in the prognosis of beta1-,beta2- and gamma-myelomas was no testablished.

We had shown previously that the prevalence of human T-cell leukemia/lymphoma virus type I (HTLV-I)-antibody positivity is high in Jamaican non-Hodgkin's lymphoma (NHL) patients and that virus-positive patients have the clinical features and poor prognosis of adult T-cell leukemia/lymphoma (ATL). Sixty-two % of 45 NHL patients diagnosed consecutively between 2/1/82 and 1/31/84 and studied prospectively were HTLV-I-antibody positive. Skin involvement (38%), hypercalcemia (44%), and leukemia (40%) were unusually prevalent and there was a strong association (p less than 0.05) with HTLV-I-antibody positivity. Fifty-two % of the patients had bone marrow infiltration, and 74% of these patients were HTLV-I-antibody positive (p = 0.06). Lymphadenopathy (96%), hepatomegaly (60%), and splenomegaly (25%) were detected with about the same frequency as in other series of NHL patients with advanced disease, and 61-88% of these patients were HTLV-I-antibody positive. Patients were classified into those with "typical ATL" (NHL associated with 2 of the 4 features i) hypercalcemia; ii) histologically proven skin infiltration; iii) leukemia; and iv) bone marrow infiltration, providing that the morphology of infiltrating or leukemic cells was characteristic of ATL; those "consistent with ATL" (NHL associated with 1 of these 4 features); and "non-ATL" (NHL without any of these 4 additional features). Thirty-two (71%) of the NHL patients were ATL patients, i.e., had features typical of or consistent with ATL, and 78% of these were HTLV-I-antibody positive. HTLV-I provirus was detected in tumour cells of all HTLV-I-antibody positive patients tested. Three (23%) of the non-ATL patients were HTLV-I-antibody positive. There was no correlation between histopathological features and the clinical classification or HTLV-I-antibody positivity. Median survival of ATL and non-ATL patients was 16 and 53 weeks. Although the disease was usually fulminant, 34% of the ATL patients had a subacute or chronic course. Skin involvement and leukemia were prominent in these patients. Hypercalcemia was the chief prognostic determinant. Median survival of hypercalcemic and normocalcemic ATL patients was 13 and 86 weeks (p less than 0.05). Hypercalcemia caused 10 deaths, infections 12, and death was due to tumour progression in 4 patients. Infections were usually due to pyogenic organisms and only 2 patients had systemic opportunistic infections. Six (27%) of 22 chronic lymphocytic leukemic (CLL) patients were HTLV-I-antibody positive.(ABSTRACT TRUNCATED AT 400 WORDS)

Clinical and histopathologic material from 42 patients with peripheral T-cell lymphoma (PTCL) was reviewed. The median age was 63.5 years (range, 11-97 years). The male:female ratio was 2.8:1. Prior immune or lymphoproliferative diseases occurred in 36% of the patients. PTCL was advanced at presentation with B symptoms (67%), generalized adenopathy (69%), and stage III/IV disease (79%). Suspected lung or pleural involvement (21%), hepatomegaly (29%), and splenomegaly (43%) were common; marrow involvement was documented in 37% of the patients at presentation and in 51% of patients during the illness. Hypercalcemia and eosinophilia occurred in 19% and 29% of patients, respectively. Among patients receiving combination chemotherapy (BCOP, CHOP, BACOP, COMLA), eight (24%) of 33 achieved a complete remission and only four (12%) of 33 had a sustained complete remission. The median survival for PTCL was 11 months. Because of the poor response to standard therapy, clinical trials should identify cases of PTCL and evaluate newer regimens in this subset of aggressive lymphoma.

An autopsy case of adult T cell leukemia associated with hypercalcemia and hyperplastic parathyroid glands is reported. A 51-year-old man complained of systemic lymphadenopathy and hepato-splenomegaly; a diagnosis of adult T cell leukemia was made based on clinico-pathological findings. The pathogenesis of hypercalcemia in adult T cell leukemia is discussed. However, cases associated with hyperplasia of the parathyroid gland are very rare. We emphasize the role of the parathyroid gland in the pathogenesis of hypercalcemia in adult T cell leukemia.

A 31-year-old woman presented with hypercalcemia, anemia, azotemia, and splenomegaly. Extensive laboratory studies failed to establish the diagnosis, though sarcoidosis seemed likely on the basis of marked hypercalciuria and restrictive lung disease. Conjunctival biopsy showed noncaseating epithelioid granulomas, confirming the clinical diagnosis. Conjunctival biopsy deserves consideration in the evaluation of the patient with unexplained hypercalcemia or other findings suggestive of saroidosis.

A 24 year old patient with epigastric pain, polyuria, polydipsia and hypercalcemia was admitted to the hospital. Besides the frequent causes of hypercalcemia such as primary hyperparathyroidism and malignancy-related hypercalcemia we had to consider sarcoidosis because of massive splenomegaly. The interstitial lung disease shown on x-ray films of the chest, the epithelioid granulomas in lung tissue and the increased ACE confirmed the diagnosis of sarcoidosis. Hypercalcemia is found in less than 5% of all cases with sarcoidosis. After treatment with steroids, diphosphonates and diuretics all symptoms and the hypercalcemia improved.

A 59-year-old man was admitted in July, 1985 because of generalized lymphadenopathy and hypercalcemia. The biopsy specimen of the left inguinal lymph node showed diffuse large cell lymphoma. He achieved a complete remission (CR) in July, 1986 by CHOP therapy. In January, 1992, he visited the outpatient clinic with splenomegaly, and swelling of the left axillary and left supraclavicular lymph nodes. The biopsy specimen of the axillary lymph node showed follicular small cleaved cell lymphoma. Because the spleen and the lymph nodes regressed after the biopsy, he has been followed up without any specific treatment for lymphoma. Histologic change from low-grade lymphoma into more aggressive histologic pattern is well documented. However the converse phenomenon, occurrence of low-grade lymphoma after intermediate-, or high-grade lymphoma has rarely been reported. Histological examination is mandatory when a patient with diffuse large cell lymphoma is suspected to have relapsing disease after the long-term CR.

Twenty-six cases of adult T-cell leukemia/lymphoma (ATLL) were identified between 1983 and 1991 in Martinique (French West Indies). There were 14 men and 12 women, all of mixed racial descent and born in Martinique. Their ages ranged from 23 to 95 years. The main clinical and laboratory features at initial presentation were peripheral lymphadenopathy (22 cases), hepatomegaly (11 cases), splenomegaly (10 cases), cutaneous lesions (12 cases), hypercalcemia (16 cases), refractory infection by Strongyloides stercoralis (12 cases), and pre-existing autoimmune disorders (4 cases). All patients had absolute lymphocytosis with circulating pleomorphic abnormal lymphocytes. The prognosis was poor, with most patients (20 cases) surviving for less than 6 months. Although the overall clinicopathologic features of ATLL in this series are similar to those described in previous reports, we observed three additional points of interest: a high association with Strongyloides infection, an increased incidence of tropical spastic paresis/HTLV-1 associated myelopathy (TSP/HAM) among the relatives of the patients (5 cases), and the presence of prior collagen vascular diseases.

A 64-year-old woman is reported with Stage I (Rai) chronic lymphocytic leukaemia (CLL), in whom hypercalcemia developed when an increased proportion of prolymphocytic cells characterized a transformation of CLL in prolymphocytoid leukaemia (CLL/PL). Although hypercalcemia is more frequently found in T-cell leukaemia associated with human T lymphotropic lymphocyte type I, scattered reports indicate that patients with B-CLL can also be affected with this metabolic disturbance. The case described here, progressed with an indolent course of CLL for 26 months, when she was admitted with a very aggressive disease characterized by a high WBC count, splenomegaly and hypercalcemia. Despite an effort to achieve a clinical remission, she failed treatment and death was attributed to unresponsive hypercalcemia. The mechanism of hypercalcemia in such cases is unclear as no parathyroid adenoma or second malignant tumor was found ante mortem. This electrolytic disturbance would appear to be a direct consequence of the transforming leukaemia and a possible mechanism involving a secreted humoral factor that could lead to altered calcium metabolism.
