[Allogenic bone marrow grafts (author's transl)].

Bone marrow transplantation is a major therapeutic approach for treatment of patients with severe aplastic anemia or acute leukemia refractory to chemotherapy. It is possible only if an HLA matched sibing is found. ABO compatibility is not necessary. The conditionning regimen includes high doses of cyclophosphamide associated or not with a 1 000 rads total body irradiation. In acute leukemia, the two year percentage survival is 17%, in aplastic anemia it is 40%. Complications are immunologic : rejection, graft versus host disease and persistent severe immune deficiency.

Search for nucleic acid sequences complementary to a murine oncornaviral genome in poly(A)-rich RNA of human leukemic cells.

The presence of viral-like sequences in the RNA of various types of leukemic cells was investigated by hybridizing cellular poly(A)-containing RNA with cDNA synthesized in an endogenous system of purified Moloney murine sarcoma virus [M-MSV-(MLV)]. Poly(A)-RNA-cDNA hybrids were detected by assaying their resistance to S1 nuclease. Hybrids were found in 22 out of the 46 leukemias that were tested. None of the controls, including material obtained from buffy coats, bone marrow cells, and a continuous human cell line, was positive. Positive cases were found in all the different categories of leukemias with the exception of chronic myelogenous leukemias. There was no definite corelation between the category of leukemia and positivity. A few cases contained a very high proportion of poly(A)-RNA-cDNA hybrid.

[Hormone replacement therapy in breast cancer patients: a study of 230 patients, with a case-control study].

OBJECTIVES: After recalling the classical contra-indication of hormone replacement therapy (HRT) concerning patients with a personal history of breast cancer (BC), and arguments that may be opposed, the authors report the present results of a prospective study undertaken in the Center of Breast Diseases in Saint-Louis hospital in Paris since February 1992. PATIENTS AND METHODS: By April 2001, 230 patients had been included. A free interval of 2 years at least since the treatment of the primary BC has been observed. The reasons for prescribing HRT were vasomotor troubles (flushes, nightly sweats) or a dyspareunia, which were severe and not controlled by non-hormonal treatments. There was also an indication of a major osteoporotic or cardiovascular danger. In fact, many of these patients had a premature, artificial, chemo-induced menopause. The HRT most often used was an estro-progestin association (estradiol + a progestin compound) given either continuously or with a 5-d interruption each month. The mean duration of treatment was 2.5 years. RESULTS: Results, concerning the improvement of menopause troubles, were remarkable in the great majority of troubles. HRT had to be stopped in 39 cases, reading as follows: 17 cases for relapses (seven local, six in the contro-lateral breast and four metastases (7%)). Also, 22 patients (9%) interrupted their HRT for serious side-effects. A case-control study did not show any significant difference between with and without HRT patients concerning the overall survival without relapse. DISCUSSION AND CONCLUSIONS: Quality of life of patients was often substantially improved, and a deleterious effect on the cancer disease was not found. Our results are in agreement with the literature from other countries. However, one must be cautious. In such circumstances, HRT must be prescribed with the informed consent of the patients and delivered in appropriate hospital and university centers. It is wished that large randomised prospective studies may be undertaken.

Future trends in cancer treatment and emesis control.

The treatment of cancer patients has improved over the last few years for a variety of reasons. These include improvements in diagnosis, more potent chemotherapeutic drugs and the introduction of new ways of containing or eliminating cancers by the use of multi-modality treatment regimens often facilitated by the use of chemoprotective agents. Cancer patients have also benefited from an increased awareness of their needs, with health care professionals paying attention to toxicities of treatment and optimising treatment schedules to combine the best possible medical outcome with patient comfort and acceptability of treatment. Thus not all the advances seen in the management of cancer patients have relied upon the introduction of novel anti-tumour agents; important advances have been made by the optimal use of existing drugs, the revision of treatment schedules and better control of the side effects of treatment. One of the more distressing side effects of cancer chemotherapy, having a profound effect on its acceptability to patients, is nausea and vomiting. The introduction over the last 3 years, of ondansetron, the first generally available 5-HT3 receptor antagonist, has had beneficial effects on the management of patients. Through improvements in anti-emetic control ondansetron has provided a better quality of life and is now beginning to impact on the design and administration of conventional chemotherapy treatment schedules. This paper reviews the changes that have been seen with the use of ondansetron and makes several suggestions about areas where clinicians might find a beneficial role for 5-HT3 receptor antagonists.

Fetal hemangiolymphangioma: a case report.

Hemangiolymphangioma is a malformation of both lymphatic and blood vessels. We present a case of fetal abdominal hemolymphangioma diagnosed by ultrasound at 27 weeks of gestation. The extensive fetal involvement, and the diagnosis before fetal viability led us to propose medical termination of pregnancy. This represents the second reported case of prenatal diagnosis of this malformation.
