Low-dose cytarabine versus intensive chemotherapy in the treatment of acute nonlymphocytic leukemia in the elderly.

We conducted a randomized multicenter trial comparing low-dose cytarabine (LD ARA-C) (20 mg/m2 for 21 days) with an intensive chemotherapy (rubidazone [a daunorubicin-derived agent], 100 mg/m2 for 4 days, ARA-C 200 mg/m2 for 7 days) in 87 patients over 65 years of age with de novo acute nonlymphocytic leukemia (ANLL). Forty-one patients received LD ARA-C and 46 received intensive chemotherapy. The number of complete remissions (CRs) but also of early deaths was higher in the intensive chemotherapy group, while partial remissions (PRs) and failures were more frequent in the LD ARA-C group (P less than .001). Infectious complications during induction treatment were more numerous and more severe in the intensive chemotherapy group (P less than .01). Patients treated with LD ARA-C required fewer RBC transfusions (P less than .02), fewer platelet transfusions (P less than .01), and had a shorter hospital stay for induction treatment (P less than .01). Overall survival and CR duration were not significantly different in either group. In the LD ARA-C group, the survival of patients with PR and those of patients in CRs was identical. We conclude that in a selected group of elderly patients with de novo ANLL a higher number of CRs may be obtained with intensive chemotherapy, but that with LD ARA-C, the number of early deaths is lower, and long-lasting PRs are obtained, resulting in a similar overall survival.

Mediastinal tumor size and response to chemotherapy are the only prognostic factors in supradiaphragmatic Hodgkin's disease treated by ABVD plus radiotherapy: ten-year results of the Paris-Ouest-France 81/12 trial, including 262 patients.

PURPOSE: To identify prognostic factors in 262 patients with supradiaphragmatic Hodgkin's disease (HD), clinical stages (CS) I and II, prospectively treated between 1981 and 1988 according to the Paris-Ouest-France (POF) 81/12 protocol by three 1-month cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine plus methylprednisone (ABVD-MP) followed by subtotal nodal irradiation (RT). PATIENTS AND METHODS: The size of mediastinal tumor (MT) was measured in all patients: 66 did not have MT (NoMT); 105 had a small-size MT (SSMT), ie, mediastinal mass ratio (MMR) less than 0.33; 58 had a medium-size MT (MSMT), ie, MMR > or = 0.33 and less than 0.45; and 33 had a bulky MT (BuMT), ie, MMR > or = 0.45. All patients received three cycles (CS IA, one cycle only) of ABVD-MP; patients in partial remission (PR) or complete remission (CR) after chemotherapy (CT) received supradiaphragmatic RT (involved fields, 40 Gy; adjacent fields, 30 Gy) plus lumboaortic and splenic RT (30 Gy); patients not in CR or PR after CT received salvage CT. RESULTS: Two hundred seventeen patients (82.8%) entered CR after CT and 258 (98.5%) after RT. Ten-year freedom-from-progression (FFP) and survival rateswere 88.6% and 89.4%, respectively. According to univariate analysis, MT size and post-CT status were the only factors to influence both FFP and survival. For patients with NoMT or SSMT, those with MSMT, and those with BuMT, FFP rates were 94.1%, 87.0%, and 63.0% (P < .001), respectively, while corresponding survival rates were 92.6%, 87.2%, and 78.2% (P < .05). FFP rates were significantly different between the patients who achieved CR and those who did not achieve CR after CT: 94.6% versus 65.3% (P < .001); corresponding survival rates were 89.9% and 73.7% (P < .01). Multivariate analysis confirmed that MT size and post-CT status were the only two prognostic factors for FFP; for survival, the same two characteristics, as well as age (< 40 v > or = 40 years), significantly affected prognosis. We were thus able to identify three groups. The 33 patients (12.6%) with a BuMT had 10-year FFP and survival rates of 63.0% and 78.2%, respectively. Of 229 patients without BuMT, the 195 who attained CR after CT had an optimal prognosis (FFP, 96.6%; survival, 93.6%), while those who failed to achieve CR after CT had an intermediate prognosis (FFP, 68.8%; survival, 77.6%). CONCLUSION: These results demonstrate the independent impact on HD prognosis of tumor burden and post-CT status.

Granulocyte colony-stimulating factor after intensive consolidation chemotherapy in acute myeloid leukemia: results of a randomized trial of the Groupe Ouest-Est Leucémies Aigues Myeloblastiques.

PURPOSE: Ten years after the first clinical studies, the clinical impact of myeloid growth factors in acute myeloid leukemia is still unclear. One of the objectives of the Groupe Ouest-Est Leucémies Aigues Myeloblastiques (GOELAM) 2 trial was to evaluate the benefit of granulocyte colony-stimulating factor (GCSF) given only after the two courses of intensive consolidation chemotherapy (ICC) used to maintain complete remission (CR). PATIENTS AND METHODS: One hundred ninety-four patients who were in CR after induction treatment were randomly assigned to receive G-CSF (100 patients) or no G-CSF (94 patients) after two courses of ICC (ICC 1, high-dose cytarabine plus mitoxantrone; ICC 2, amsacrine plus etoposide). G-CSF (filgrastim) was administered from the day after chemotherapy until granulocyte recovery at a daily dose of 5 microg/kg. RESULTS: In the G-CSF group, the median duration of neutropenia (< 0.5 x 10(9)/L) was dramatically reduced, both after ICC 1 (12 v 19 days, P <.001) and after ICC 2 (20 v 28 days, P <.001). The median duration of hospitalization was also significantly shorter in the G-CSF group (24 v 27 days after ICC 1, P <.001; 29 v 34 days after ICC 2, P <. 001). The median duration of intravenous antibiotics was significantly reduced after ICC 1 and ICC 2, and the median duration of antifungal therapy was significantly reduced after ICC 1. However, the incidence of microbiologically documented infections, the toxic death rate, the 2-year disease-free survival, and the 2-year overall survival were not affected by G-CSF administration. Moreover, the median interval between ICC1 and ICC2 was reduced by only 2 days, and the number of patients undergoing ICC2 was not increased in the G-CSF arm. CONCLUSION: G-CSF should be administered routinely after ICC to reduce the duration of neutropenia and hospitalization. However, G-CSF did not seem to significantly increase the feasibility of this two-course program or modify overall outcome.

Effects of clinical combinations of antileukemic drugs on DNA ligase from human thymocytes and normal, stimulated, or leukemic lymphocytes.

Human DNA ligase was purified from different kinds of immunocompetent cells: thymocytes, normal and stimulated lymphocytes, blasts from ALL (Burkitt and non-T, non-B) and ANLL (M1, M2, and M5). Based upon the protocol for the treatment of these leukemias, the purified enzymes were assayed in the presence of routinely used combinations of antileukemic drugs. At the range of concentration tested (between 0.1 and 5 microM) some drugs taken separately were totally inactive on the enzyme from the different sources. For those being inhibitory, when used in combination their effect was always different from what was observed when the compound was tested alone. Some combinations were more effective in inhibiting the enzyme from leukemic than from normal cells (vincristine + cyclophosphamide + prednisone in ALL and rubidazone + Ara-C, Ara-C + m-AMSA, in ANLL). However, some combinations of drugs are without effect on ligase from leukemic cells at this dose range (vincristine + rubidazone + Ara-C + prednisone and adriamycin + asparaginase + Ara-C in ALL or etoposide + Ara-C, adriamycin + cyclophosphamide in ANLL). This is the first direct observation of the effect of cytostatic drugs on DNA ligase, a key enzyme of the DNA replication and repair process. The clinical consequences of these observations are discussed in an attempt to selectively inhibit replication, thereby division, of cancer cells.

Jumping translocation in acute leukemia of myelomonocytic lineage: a case report and review of the literature.

Jumping translocation (JT) is a very rare cytogenetic event, occurring especially in cancer. We describe a case of secondary acute monocytic leukemia (AML5b) with a JT involving the 3q13-3qter segment and leading to a partial trisomy 3. Each clone with JT was associated with trisomy 8 or tetrasomy 8. The literature of JT in AML cases is reviewed: only 13 cases of AML associated with JT have been previously described, seven of which are AML4/5 FAB subtype. Jumping translocation involvement in leukemogenesis is discussed. Leukemia (2000) 14, 119-122.

dATP-mediated inhibition of DNA ligase by 2'-deoxycoformycin in T and B cell leukemia.

2'-Deoxycoformycin (dCF), a potent adenosine deaminase inhibitor, has been reported to display greater toxicity for T than for B lymphoblasts. Since this compound can block DNA replication and since this effect is mediated by the intracellular ATP/dATP balance, its possible effect on DNA ligase was investigated. dCF at relatively low concentrations (1 microM), in association with dATP (100 microM), is a strong inhibitor of DNA ligase in T blasts, whereas it has no significant effect in B blasts at this concentration. The AMP-ligase complex is the target of the observed inhibition because the combined presence of the inhibitor and dATP results in a more stable dAMP-ligase complex. Because of this observation and of the greater adenosine deaminase activity observed in T cells, the dATP mediated dCF inhibition of ligase might be the crucial replication target of T cell toxicity. These observations are discussed in terms of T immunodeficiencies including Graft Versus Host Disease and related syndromes.

P-glycoprotein (P-170) and CD34 expression in adult acute myeloid leukemia (AML).

We investigated the prognosis value of CD34 and P-170 expression in blast cells of adult patients affected by de novo acute myeloid leukemia (AML). CD34 antigen was analyzed by indirect immunofluorescence (IFI) and alkaline phosphatase-labeled streptavidin biotine (AP-LSAB) in 62 patients (median age: 51 years). P-170 expression was determined by AP-LSAB in 51 cases using JSB1 and C219 monoclonal antibodies. All patients were treated with conventional chemotherapy induction regimen. Follow-up was from 6 to 79 months. Complete remission (CR) rate was not statistically different between CD34+ and CD34- patients (67 vs. 84%, p = 0.2). The duration of CR and survival were not influenced by CD34 expression. Karyotype abnormalities were more frequent among MDR+ patients (65 vs. 21%, p < 0.01). CR rate was statistically lower in MDR+ patients as compared to MDR- patients (63 vs. 96%, p = 0.01). Median disease-free survival (DFS) was shorter for MDR+ patients but the difference was not significant (5 vs. 10 months, p = 0.09). Patients who were positive for both parameters CD34 and P-170, had a poor prognosis with a 50 vs. 100% CR rate for CD34/P-170 negative patients, (p = 0.002), a lower median DFS (3 vs. 12 months, p = 0.01) and overall survival (OS) (3 vs. 14.5 months, p = 0.01). Results of cytogenetic analysis did not influence CR rate but the relapse rate was higher, although not significant, for the patients with unfavorable karyotype (63 vs. 33%). The seven CD34+/MDR+ patients with poor prognosis karyotype had a statistically lower CR rate, median DFS and OS than the 7 CD34-/MDR- patients with normal or favorable karyotype (CR: 29% vs. 100%, p = 0.02), (DFS: 3 vs. > 12 months, p = 0.01), (OS: 4 vs. > 12 months, p = 0.02). Our data indicate that P-170 but not CD34 expression is predictive for a lower CR rate. The identification of a bad prognosis subgroup of CD34+/MDR+ AML patients (and especially those with poor prognosis karyotype) has to be confirmed on larger series using uniform methodology.

Inapparent polycythemia vera: an unrecognized diagnosis.

PURPOSE: The Polycythemia Vera Study Group (PVSG) has established useful criteria for the diagnosis of polycythemia vera. In some circumstances, an increase of plasma volume (PV) masks that of red cell mass (RCM), with hemoglobin (Hb) and hematocrit (Ht) remaining normal. This defines the concept of inapparent polycythemia. PATIENTS AND METHODS: One hundred and three patients seen in the hematology unit with the diagnosis of polycythemia vera were studied. There were 55 males and 48 females with a median age of 59 years. Ninety-five patients fulfilled the PVSG criteria. Spontaneous erythroid colonies and low serum erythropoietin level confirmed the diagnosis in the 8 other cases. Patients were classified according to Hb and Ht level. RESULTS: Group A consisted of 85 patients with increased Hb and Ht defined, respectively, by Hb > 18 g/dl, Ht > 0.52 in males and Hb > 16 g/dL, Ht>0.47 in females. Group B included 18 patients (17%) with inapparent polycythemia vera (IPV) defined by a normal Hb and Ht value at diagnosis. In this group, the reasons to perform RCM were as follows: splenomegaly associated with increased platelets and/or leucocytes counts (n = 8), portal vein thrombosis (n = 5), increased platelets or leucocytes counts without splenomegaly (n = 3), and isolated splenomegaly (n = 2). The two groups were balanced in terms of age, sex, leucocyte, serum iron, and platelet level. Hemoglobin and Ht levels were significantly different between the two groups. The difference between the PV was indeed highly significant. The mean PV increase was + 9.5% (nL < +20%) in group A versus + 36.3% in group B (P < 0.00005). Red cell mass was not different between the two groups. CONCLUSIONS: Increased Hb or Ht should constitute the sole criteria for RCM determination. In the context of portal vein thrombosis, isolated hyperleucocytosis, thrombocytosis, or splenomegaly, a RCM should be performed. The frequency of IPV remains to be specified but the diagnosis of polycythemia vera is probably underestimated.

Splenectomy in idiopathic thrombocytopenic purpura: its correlation with the sequestration of autologous indium-111-labeled platelets.

We present a retrospective analysis of 111In-platelet sequestration studies in 111 patients with the clinical diagnosis of idiopathic thrombocytopenic purpura (ITP). Fifty-one of these patients underwent splenectomy, independent of the results of the 111In-platelet studies to determine if these isotopic results could accurately predict a beneficial response to splenectomy. Between January 1984 and June 1990, 111 patients who presented with ITP were subjected to a study of autologous 111In-labeled platelets through autotransfusion. The platelet sequestration site was splenic (81%), mixed (12%), or hepatic (7%). Fifty-one patients with persistent drug-resistant thrombocytopenia underwent splenectomy regardless of the isotopic results: 33 patients beyond 6 mo after diagnosis and 18 with high hemorrhagic risks before this delay. The follow-up median duration was 2.9 yr. Thirty-three of the 38 patients with splenic sequestration showed a normalized platelet count, as opposed to 2 of the 13 with mixed or hepatic sequestration (p < 0.001). In addition, platelet survival extended beyond 8 days in six patients, with no apparent sequestration site. The platelet isotopic study performed with this technique appears to be indicated in ITP: it guides clinicians in their decision to perform splenectomy and relates to a more central mechanism certain thrombocytopenias that are inappropriately categorized as ITP.

DNA ligases in human leukemia.

Following partial purification on sucrose gradient and/or phosphocellulose chromatography, DNA ligase was tested in peripheral white blood and bone marrow cells of nearly 100 patients with various kinds of leukemias, mainly acute leukemias. Terminal deoxynucleotidyl transferase (TdT) was tested in parallel. DNA ligase of acute myeloblastic leukemia (AML) was extracted with the same sedimentation coefficient (5.5S) on sucrose gradient, and eluted with the same KCl molarity (0.3 M) than the one extracted from normal lymphocytes. Acute lymphoblastic leukemias (ALL) were characterized by no detectable DNA ligase activity--in most T or non T-non B-ALL, or a low activity in pre-B and B (Burkitt type) ALL, with levels similar to the one observed in chronic lymphocytic leukemia (CLL). An inverse relationship was observed between DNA-ligase and TdT in ALL, ligase being undetectable in cells positive for TdT and being present in some T or non T-non B, and in all pre-B and B-ALL negative for TdT. AML and chronic myelocytic leukemia (CML) were characterized by a markedly higher DNA-ligase activity. This activity was higher in the most differentiated subtypes--M2, M3 and M4 subtypes of FAB classification--and in CML. Moreover a high degree of correlation was observed in AML between the DNA ligase activity and the S phase fraction measured by 3 H-thymidine autoradiography or flow cytophotometry on the total cell sampling. Besides their clinical interest, these results are discussed in relation with the role of DNA-ligase in DNA replication and repair.

Long-term follow-up of allogeneic bone marrow transplantation in patients with poor prognosis non-Hodgkin's lymphoma.

Relapsed or very aggressive high-grade NHL and refractory low-grade NHL have a poor clinical outcome. Autologous BMT may be used but is of limited efficacy in these cases. Allogeneic BMT offers the advantage of tumour-free bone marrow and a possible GVL effect. Between 1987 and 1996, 13 patients (median age 31 years) suffering from lymphoid malignancies underwent allo-BMT. Four patients had low-grade NHL, three intermediate-grade and six high-grade NHL. Three patients were grafted with evolutive disease, four were in partial remission after several courses of chemotherapy, two were in CR2 and four were in CR1 after initial therapy. The mean number of prior treatments was 2.7 (1-6). Median time from diagnosis to BMT was 25 months (4-90). The conditioning regimen consisted of cyclophosphamide (120 mg/kg/day for all, plus VP16 in one case) and total body irradiation. Five out of the seven patients who were not in CR at the time of transplantation entered CR after BMT. Eight patients developed acute GVHD grade > or = II and four had chronic GVHD. Nine patients are alive, eight in CR with a median follow-up of 49.8 months post BMT (2-125). Overall survival is 67.3% and the median time for EFS is 102 months. Two patients with low-grade NHL relapsed 61 and 102 months post BMT and were treated with DLI. One patient with a stage IV SLL had a partial remission and one with multiple cutaneous localisation of FL entered CR after grade IV acute GVHD. Allo-BMT is a highly effective treatment for advanced poor prognosis lymphoid malignancies with acceptable toxicity. Moreover, DLI can be effective in relapsing patients.

Cytogenetic studies in 56 cases with Ph1-positive hematologic disorders.

Karyotypes were examined in 56 cases of Ph1-positive hematologic disorders based on direct examination of bone marrow material and culture of blood for 24 hr without phytohemagglutinin (PHA). Various banding techniques (Q, followed by R or C, where necessary) were used. The series of patients consisted of 21 females and 35 males with the ages ranging from 3 to 72 years. In three cases, the clinical and hematologic picture at the time of diagnosis and karyotyping was not compatible with chronic myeloid leukemia (CML): 1 case had acute myeloblastic leukemia (AML), another acute lymphoblastic leukemia (ALL) and the third subacute myeloid leucosis. The results are as follows: In three cases (two female, one male), no Ph1 translocation could be demonstrated in any of the metaphases either with Q- or R-banding. In 50 cases (19 female, 31 male), a standard Ph1 translocation, t(9;22)(q34;q11), was observed. In two of these cases, ages 45 and 47, the Ph1 translocation was accompanied by loss of the Y chromosome in all the metaphases examined. Finally, in three cases (all male), variant Ph1-translocations were found: t(7;9)(9;22)(q35?;q31?;q11), and t(1;9)(9;22)(q21;134;q11).

Multidrug resistance in aggressive lymphoproliferative disorders of T and natural-killer origin.

The measurement of rhodamine 123 (Rho123) efflux in hematological malignancies, using flow-cytometry, provides an accurate assessment of multidrug resistance (MDR) of both P-glycoprotein and MRP. While their normal counterparts display high levels of PgP and Rho123 efflux, we investigated the MDR status of marked T/NK proliferations. When diagnosed according to natural killer (NK) markers (CD16, CD56, CD57) 8 of nine NK lymphoproliferative disorders (LPD) were markedly positive (3 NK non Hodgkin's lymphomas (NHL), 1 NK lymphoproliferative disease of large granular lymphocytes (LGL), and 5 T/NK LGL). These results are in accordance with the observed response to chemotherapy in the treated cases. Mature T LPD (prolymphocytic leukemia (PLL), and NHL) cells gave varying results, as did cells from Sezary syndromes. Marked Rho123 efflux was detected in the two cases of T-PLL suggesting the expression of MRP as previously described. Immature T-lymphomas or leukemias (6 cases) were all negative. These data should be considered in relation to NK proliferations which clearly display an MDR phenotype and therefore raise the question, of the relevance of this phenotype in normal cells, and secondly of the negativity of immature T-LPD. The latter could indicate that MDR inhibitors may be superfluous in the initial treatment of acute lymphoblastic leukemia (ALL). Finally the resistance to treatment of T-ALL or mature T cells LPD invokes the importance of exploring other mechanisms of drug resistance such as the lung resistance related protein (LRP).

Prophylactic use of itraconazole for the prevention of invasive pulmonary aspergillosis in high risk neutropenic patients.

Invasive pulmonary aspergillosis (IPA) is an increasing cause of morbidity and mortality in patients with hematologic malignancies. A major program of construction work close to our unit prompted us to evaluate the efficacy of itraconazole prophylaxis in preventing IPA in these patients. During September 1994 to December 1995, 77 patients undergoing 96 neutropenic episodes (mean duration, 19.3 days +/- 9.1) received itraconazole as antifungal prophylaxis. All patients were treated in laminar air flow rooms. Itraconazole was administered at a loading dose of 600mg/d, (day 1 to day 3) and 400mg/d on the following days, in 87 instances. In the remaining episodes, the daily dose was 200 or 400mg. Oral doses were adjusted to reach a plasma itraconazole level (PIL) above 1000ng/l. In cases of inadequate PIL or poor oral intake, IV AmphoB was started at a 20 mg daily dose. Five cases of IPA (proven n = 2, probable n = 3) were observed. This represents an incidence of 5.2% of the total number of episodes. One out of 67 (2%) treatment episodes with adequate PIL were associated with IPA as compared to 4 of 29 (14%) episodes with inadequate PIL, (p < 0.02). AmphoB was added in 28 cases because of low PIL (n = 25), and/or antibiotic-resistant fever persistent pulmonary infiltrate (n = 8). These results need to be interpreted with caution, because of the absence of randomization or a control group. The efficacy of Itraconazole in neutropenic patients with high risk IPA has to be confirmed on larger and prospective studies.

Multifactorial drug-resistance phenomenon in acute leukemias: impact of P170-MDR1, LRP56 protein, glutathione-transferases and metallothionein systems on clinical outcome.

The multidrug resistance phenomenon can be observed in cases which do not express the P170 protein and these cases are suspected as having activated different resistance phenomena. Four phenomena were studied at the time of diagnosis in a series of 35 lymphoblastic and 25 myeloblastic acute (de novo) leukemias, by an immunocytochemical method. Two energetic drug transport processes were investigated: the classical MDR/P170 and the P110/LRP56 proteins, and two physiological detoxifying activities such as the glutathione transferases (GST alpha, mu, pi) and the metallothioneins (Mts). The results demonstrate that these phenomena are independent but their synergic activity can increase their impact on the outcome. P110/LRP56 positive cases demonstrated 48.8% complete remission (CR) rate compared to 71.4% for negative tests. When P170 and P110 were both positive or negative, the CR rates were 27.3% and 81.8% respectively (p = 0.0120), and survival curves were also different (p = 0.030). The CR rate in AML or ALL is weakly affected by GST pi, alpha or mu but relapses are more frequently observed for Positive-GST pi ALL (p = 0.0658). Patients with both P170 and GST pi positive reactions had a 53.3% CR rate compared to 78.9% for both negative reactions. Survival curves for these two groups were different. The CR rate in AMl was 100% for Mts positive and 43.7% for negative cases (p = 0.050), however the median survival was totally different for these two groups (p = 0.046). CR rates were 26.6% for patients who were P170 positive and Mts negative compared to 100% for P170 negative and Mts positive (p = 0.038) patients. Survival curves were also different (p = 0.0510). We conclude that these four mechanisms induce an independent drug resistance but their synergic action increase their impact on the outcome. The metallothioneins seem to have a major impact on the drug resistance phenomenon and its effect should be investigated with high priority, in the light of these results.

[Stenosis of the branches of the pulmonary artery caused by Hodgkin's lymphadenopathies]. / Sténoses des branches de l'artère pulmonaire par des adénopathies hodgkiniennes.

A 22 year old patient was admitted to hospital for dyspnoea and haemoptysis. Cardiac catheterisation showed a pressure gradient between the main pulmonary artery and its branches. Pulmonary angiography showed appearances of extrinsic compression of the branches of the pulmonary artery. This was shown to be caused by lymphadenopathy on CT scan and Hodgkin's disease was diagnosed after surgical biopsy. The pressure gradient between the main pulmonary artery and its distal branches almost completely regressed after chemotherapy and radiotherapy.

[Agranulocytosis and connectivitis different from Felty's syndrome: 4 cases. Success of cyclosporin in a case]. / Agranulocytose et connectivites distinctes du syndrome de Felty: 4 observations. Succès dans un cas de la ciclosporine.

Four cases of chronic agranulocytosis in patients with systemic diseases different from Felty's syndrome are reported. Two patients had primary Sjögren's syndrome (confirmed in one, suspected in the other), one had systemic lupus erythematosus and the last patient had an unclassifiable connective tissue disease. Only one severe infection was recorded. The pathophysiological mechanisms involved are discussed. There is a strong suspicion that the cytopenia is of immune origin. Corticosteroid therapy was effective in all four patients. One patient who could not tolerate corticosteroids was successfully treated with cyclosporin A.

[Primary adrenal lymphoma with latent adrenal insufficiency: a case report and literature review]. / Lymphome primitif des surrénales avec insuffisance surrénalienne latente: à propos d'un nouveau cas et revue de la littérature.

We report a new case of primary adrenal lymphoma with latent adrenal insufficiency and long-term remission after hydrocortisone replacement therapy. We have analyzed 29 other cases described in the literature. This disease with poor prognosis can be revealed by an incidentally discovered, frequently bilateral, adrenal mass. Adrenal insufficiency may be latent and the diagnostic procedure should include both cortisol and ACTH determination with an additional ACTH stimulation test if appropriate. Early adrenal substitution can improve patient survival.

[Treatment of localized forms of Hodgkin's disease with 3 courses of chemotherapy (ABVD-MP) in combination with wide focal and prophylactic lumbo-splenic radiotherapy. The POF 81/12 protocol]. / Traitement des formes localisées de la maladie de Hodgkin par 3 cures de chimiothérapie (ABVD-MP) associées à une radiothérapie focale élargie et lombo-splénique prophylactique. Protocole POF 81/12.

Between October 10, 1981 and December 31, 1987, we used the Hodgkin POF 81/12 protocol to treat 235 patients aged from 5 to 65 years (mean 30 years) with localized Hodgkin's disease clinically classified as stage IA (n = 6), stage IIA (n = 128) and stage IIB (n = 53). A contiguous lesion was present in 22 cases and a mediastinal lesion in 170 cases. The patients received 3 monthly courses of ABVD-MP (doxorubicin 25, bleomycin 10, vinblastine 6, dacarbazine 375 and methylprednisolone 120 mg per sq.m intravenously on days 1 and 15), except for stage IA non-mediastinal patients who received only one course. Thereafter, in the absence of failure (lack of changes or progression under chemotherapy), a 40 Gy wide focal irradiation and a 30 Gy prophylactic lumbo-splenic irradiation were performed. Complete remission (CR) was obtained in 229 patients, and the 6 failures (4 after ABVD-MP, 2 after radiotherapy) were treated with specific programmes. On December 1, 1988 (median survival 42 months, range 12-86 months) we had recorded 9 relapses (after 9 to 51 months) and 7 deaths (2 failures, 2 relapses and 3 patients in CR: ovarian carcinoma, road accident, exploratory pleural puncture). The current actuarial relapse and survival rates at 7 years are 5 and 94 respectively. Two unfavourable forms of the disease were identified: infra-diaphragmatic with massive lumbo-aortic lesions (5 cases: 1 failure, 1 relapse) and supra-diaphragmatic with a mediastinum/chest ratio of 0,45 or more (30 cases: 5 failures, 5 relapses). In the 200 patients devoid of these 2 risk factors the results obtained were: CR 100 percent, only 2 relapses and survival at 7 years 98 percent.
