[Pregnancy after ovariectomy as a result of preservation of the embryos].

We report the first published case of pregnancy obtained with a self-preserved embryo in a woman who, in 1987, had been castrated for a tumoral and painful pelvic disease retrospectively diagnosed as endometriosis. This woman had an old-standing tuboperitoneal infertility, and in vitro fertilization had been performed, followed by cryopreservation of the embryos. Two embryos were transferred during an artificially induced oestro-progestogenic cycle. Pregnancy developed and progressed normally with a simplified therapeutic regimen. This case suggests that preservation of the embryos is a possible solution to the problem of women about to undergo medical or surgical castration and wishing to become pregnant after cure of the disease which motivated the castration.

Cytogenetics and molecular analysis in chronic myelogenous leukemia patients treated by interferon and chemotherapy.

A new combination regimen including chemotherapy and interferon was started in 1986 for the treatment of 24 chronic myelogenous leukaemia patients in chronic phase. Complete cytogenetic remission were noted in 10 patients and 6 of them are in sustained remission. The overall survival was 70% at 40 months. However, a minimal residual disease was detected in the 3 patients tested with the polymerase chain reaction. In addition no correlation was detected between the site of the breakpoint and response to therapy.

Two additional cases of t dic(9:12) in acute lymphocytic leukemia (ALL): prognosis in ALL with dic(9:12).

We report two occurrences of dic(9;12) in acute lymphoblastic leukemia and review previous cases. Cases of dic(9;12) share common features with cases of 9p and 12p rearrangements, but prognosis seems particularly good in cases of dic(9;12). The persistence of a specific dicentric in stable clones is remarkable and points to unusual centromeric behavior and/or marked selective advantage of the anomaly.

Combined therapy interferon and chemotherapy in chronic myelogenous leukemia.

In view of the results achieved by others with interferons and also with low doses of Cytosine-arabinoside, we have treated 24 patients with IFN alpha 2a and Hydroxyurea for induction, with addition of low dose Ara-C during IFN maintenance therapy when the cytogenetic results were deemed insufficient. Complete hematological responses were obtained in 75% of the cases. Cytogenetic responses were noted in 83% of 12 previously untreated (complete or almost complete response in 3) and in 50% of previously treated patients (complete or almost complete response in 3 patients).

Use of various mitogens and cell stimulation index in 21 patients with chronic lymphocytic leukaemia.

A number of mitogens was used in 21 chronic B-lymphocytic leukaemia patients. Thymidine uptake assays were performed to evaluate cell stimulation. Phytohemagglutinin and phorbol-myristate 13 acetate were found to be the most efficient on cell proliferation. Abnormal clones were found 7 times with PMA, 4 times with PHA, twice with pokeweed, but in no case with lipopolysaccharide or proteine-A. The efficiency of PHA as a B-cell activator is likely to be due to T cell mediation.

Karyotypes of 33 patients with clonal aberrations in chronic lymphocytic leukaemia. Review of 216 abnormal karyotypes in chronic lymphocytic leukaemia.

We report on 33 unpublished patients with clonal anomalies in chronic lymphocytic leukaemia. The literature was thoroughly reviewed in order 1) to quantify the frequency of anomalies found in chronic lymphocytic leukaemia and to give new status to the rarest, 2) to determine whether a given anomaly was an additional anomaly and/or a primary anomaly, and 3) to find out whether strong associations between different anomalies exist in this disease.

The 8p11 anomaly in "monoblastic" leukaemia.

We report on three cases of monoblastic leukaemia with a chromosomal breakpoint at 8p11. One of our cases exhibited a translocation t(8;16) as has been described in 12 previous cases reported in 1987. The two other cases showed respectively t(6;8) and t(8;19) and they seem to be the first two reports of variant translocation in this disease. The available cases serve to define the main characteristics of this new subtype of non lymphocytic acute leukaemia: phagocytosis in most of the cases, the possible involvement of a granulomonocytic precursor, and a common breakpoint in 8p11.

[Acute leukemia with translocation (8;16)].

Three cases of M5 acute leukemia, 1 with a t(8;16)(p11;p13), 2 with variant translocations, both with a breakpoint at band 8p11, t(6;8)(q27;p11) and t(8;19)(p11;q13) are reported and 12 other published cases reviewed. This is a rare new entity, of variable but rather poor prognosis, seen from birth to 75 years of age, with several cases in infants. Leukemic cells, which often show conspicuous phagocytic activity on bone marrow smears, bear both monocytic and granulocytic markers in at least some cases. The best therapeutic regimen is not well-defined. The molecular basis of the disorder remains to be elucidated.

Malignant histiocytosis: a specific t(2;5)(p23;q35) translocation? Review of the literature.

In this paper, the investigators report a well documented case of malignant histiocytosis (MH) with a t(2;5)(p23;q35) translocation. A breakpoint in 5q35 appears to be specific, either for the disease or for a subclass of the disease. Additional cases of MH with cytogenetics are needed. This will help to determine if one class of MH or several subclasses can be defined by cytogenetic anomaly(ies).
