Massive systemic amyloidosis associated with light-chain deposition disease.

A 72-year-old woman presented with rapidly progressive renal failure and multiple myeloma. The patient died 6 months later of severe hepatic insufficiency. The light-microscopic, immunological and ultrastructural findings showed widespread kappa-light-chain deposits including the kidneys, liver, spleen, heart, lungs, tongue, ovary, pancreas and bone marrow associated with massive AL amyloid deposits in the same organs and in the thyroid gland. The concurrent presence of two different deposits is very unusual and the possible mechanisms for such an association are discussed.

Hemibody irradiation in stage III multiple myeloma: results of 20 patients.

The advanced forms of multiple myeloma of bone, stage III, or those with a large tumoral mass, characterized by a considerable number of myeloma-cells, pose difficult problems in treatment. Little progress has been made since the introduction of the alkylating agents, and combined chemotherapy does not seem to be any more effective in terms of survival. It is these severe forms that culminate in painful symptoms which are often difficult to eliminate. The radiosensitivity of myeloma led us to treat 20 patients affected by severe forms of the disease by total body irradiation in two stages, and we analyse here the effects of treatment and the tolerance for this technique.

[Heterogeneity of large granular lymphocyte leukemia. 2 cases].

Large cell granulocytic leukemia (LCGL) or proliferative lymphocyte T gamma disease, characterized cytologically by the presence of lymphocytes with intracytoplasmic azurophil granules, raises the problem of whether or not it is monoclonal in character. However, although it may resemble a chronic lymphoid T leukemia or Felty's syndrome, it differs by the constant finding of infiltration of the splenic red pulp by large granular lymphocytes. Studies of their immunologic phenotype and functional activity produce heterogeneous results. The disease course varies considerably: the serious nature of the infections, knowledge of the physiopathologic mechanism of the neutropenia and the importance of the tumoral syndrome could represent therapeutic indications the modalities of which have still to be defined.

[Value of high-dose cytosine-arabinoside in the treatment of resistant acute leukemia].

Sixty-one patients with refractory or relapsed or secondary acute leukemia were treated with high-dose cytosine arabinoside (2-3 g/sq m in intravenous infusion every 12 hr to a 12-36 g/sq m total dose). m-Amsa or another antileukemic drug was given with cytosine arabinoside to 20 patients. Complete remission was achieved in 12 of 27 patients with acute myeloid leukemia, 5 of 8 patients with chemotherapy-induced leukemia, 3 of 7 patients with hematologic disorders in blastic crisis and 5 of 17 acute lymphoblastic leukemia patients. A similar response rate (6/16) was obtained when m-Amsa was given with cytosine-arabinoside. The median duration of remission was short (4 months in acute myeloid leukemia). Bone marrow transplantation was performed in 10 patients during the remission time. This regimen has acceptable toxicity; severe neurologic or hepatic disorders occurred in 18% of patients. These data suggest that high-dose cytosine arabinoside is an effective alternative in the treatment of resistant acute leukemia.

[Cardiac involvement in 2 cases of malignant non-Hodgkin's lymphoma. Course of cardiac involvement under chemotherapy].

In a recently published post-mortem series the incidence of cardiac lesions in malignant lymphoma was estimated at about 8.7%. These lesions rarely produce specific cardiac symptoms; they usually are late manifestations of a disease with multiple secondary lesions or are discovered at autopsy. In most patients the lesions are not limited to the heart but represent the extension to that organ of a malignant lymphoma. We observed two cases of cardiac lesions secondary to malignant non-Hodgkin lymphoma and we were able to evaluate their response to chemotherapy. In the first patient the cardiac symptoms revealed the lymphoma; in the second patient the cardiac involvement was discovered 4 years after the lymphoma was diagnosed. In both cases the cardiac lesions were detected by two-dimensional echocardiography. They presented as polypoid masses filling the right atrium and associated with periaortic thickening in the first case, and as a large heterogeneous mass including a tricuspid valve leaflet and extending to the free wall of the right ventricle in the second case. Pericardial effusion was present in the two patients. These echocardiographic findings were confirmed computerized tomography and catheterization. In the first case, followed up for one year, the echocardiographic images reverted to normality after chemotherapy. The second patient, unfortunately, did not respond to chemotherapy and deteriorated rapidly.

[Neuropathies and monoclonal dysglobulinemias].

Nine patients with peripheral neuropathy and monoclonal gammapathy are presented (4 multiple myeloma, 5 Waldenström's macroglobulinemia). Two patients had tremor and ataxia. All patients had delayed nerve conduction and increased cerebrospinal fluid protein. Symptoms of neuropathy preceded detection of serum protein abnormalities in seven cases. Nerve fiber lesions involved myelin and axons. Biphasic myelopathy with uniform separation of myelin lamellae was observed in one case of Waldenström's disease. Amyloid stains were negative. Treatment was successful in one of four patients. 185 cases of peripheral neuropathy with monoclonal gammapathy are reviewed. Pathogenic role of microvascular changes, amyloid depositions, antimyelin antibody is discussed. The role of anti MAG antibody remains unresolved. Nerve damage due to another cause is possible. The paraprotein and the neuropathy may not be directly related but both caused by the underlying condition.

[Expression of class I and class II markers on populations of leukemic cells].

The study of class I and class II antigen expression on leukemic cells brought the following conclusions: most of the leukemic cells show a slower number of class I antigenic sites than normal peripheral blood lymphocytes (PBL) but, in most cases, this does not hinder HLA typing; contrarily to normal PBL, leukemic cells seem to carry "non HLA" antigens (and/or non classical HLA antigens) which are probably responsible of the false positive reactions frequently observed at the time of HLA typing; most of the leukemic cell types express DR antigens (except those belonging to the T lineage) but DQ antigen expression (and in some cases MT antigen expression) varies depending on the cell type studied: well defined on mature B hemopathies, DQ expression is often lower than DR expression on acute leukemic cell types.

[Chronic lymphocytic leukemia, erythroblastopenia, thymolipoma].

The association of B cell chronic lymphocytic leukemia and pure red cell aplasia in a 42 year-old patient led to the discovery of a thymic enlargement. After six weeks treatment including steroids, cyclophosphamide and three courses of plasma exchange without improvement, surgical thymectomy was followed by a reticulocytosis and remission of the red cell aplasia. The tumor was a thymolipoma. Characteristics of this are thymic tumor, his connections with pure red cell aplasia and in vitro differentiation of erythroid progenitors are discussed.

[Multiple myeloma of the bones. Treatment by 2-stage whole-body irradiation. 7 cases].

Seven patients with high tumoral burden myeloma of bones were treated by two successive hemicorporeal irradiations. This treatment was strikingly effective in providing pain relief which was durable in 3 cases. It might also have reduced the tumoral mass, since partial remission was obtained in 2 cases and lasting normalization of calcaemia in one patient with a non-excreting myeloma. Its haematological side-effects did not seem to exceed those of combined chemotherapy, and its pulmonary toxicity was reduced by using corrected doses.
