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.

[A study of hematology questions on the competitive examination of medical residents 1984, 1985 and 1986].

The recently (1984) introduced new modalities for selecting the residents in France is based upon multiple choice (MCQ) questions (2/3) and written answers to patients managements problems (PMP) (1/3). MCQ and PMP are selected by a group for 8 hematologists from the 42 French schools of medicine. The process of selecting the questions, the major topics explored by these questions, the docimological quality of the questions and the most surprising errors made by the candidates are studied. Results argue for a sustained effort in order to improve the teaching of the basis of hematology in our country.

A new technique to protect ovarian function before pelvic irradiation. Heterotopic ovarian autotransplantation.

The authors describe a new technique for the subcutaneous heterotopic transplantation of the ovary before pelvic irradiation to treat Hodgkin's disease. Creation of a cavity to receive the transplant and the use of two surgical teams and the surgical microscope during the operation ensured its successful outcome. The transplanted ovary was followed up clinically and by ultrasound monitoring: ovarian cycles remained regular despite radiotherapy, and follicle growth occurred normally. In comparison to other types of oophoropexy described in the literature, the advantages of this technique included total protection of the ovary from irradiation, and conservation of ovarian function and fertility. One year after the procedure, puncture of the ovarian compartment produced a mature oocyte specimen.

[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.

[Disseminated aspergillosis in acute leukemia probably chemically-induced].

One case of invasive aspergillosis in patient with myeloblastic leukemia probably induced by chimiotherapy is reported. Aspergillosis is a severe infection in immunodepressed host with 70 to 80% of mortality. Early diagnosis can be often carried by broncho-alveolar lavage, route of entry is always pulmonary one. Rapidly established antimycotic treatment can avoid death. Laminar air flow rooms and air spores numeration allow prevention of this infection in the immunodepressed host.

Primary myeloproliferative disorder and hepatic vein thrombosis. A prospective study of erythroid colony formation in vitro in 20 patients with Budd-Chiari syndrome.

We assessed the prevalence of overt and latent primary myeloproliferative disorders in hepatic vein thrombosis. Cultures of bone marrow or peripheral blood mononuclear cells were done in 20 patients with Budd-Chiari syndrome. Erythroid colony formation in the absence of erythropoietin, which is a reliable indicator for a primary myeloproliferative disorder, was seen in 16 patients in whom Budd-Chiari syndrome was due to hepatic vein thrombosis, including 13 women aged 18 to 45 years. Among these 16 patients, the conventional criteria for the diagnosis of a primary myeloproliferative disorder were met in only 2. Primary myeloproliferative disorder, often without peripheral blood changes, is a major cause of hepatic vein thrombosis in young women.

[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.

[Tumoral medullary compressions in malignant hemopathy (a 28 cases review (author's transl)].

The authors reviewed 28 cases of tumoral medullary compressions in malignant hemopathy. At once they point out 2 groups according to the fact that this compression is or not the revealing symptom of the disease. With regard to different data, that is to say, preoperative clinical examination with complementary investigations, and then results obtained from decompressive laminectomy followed or not with complementary therapy; the elements of the functional prognosis are analysed. They insist on frequency of medullary compression in a neuro surgical environment, as the revealing symptom of the hematologic disease and its immediate decompressive therapy is emphasized.
