[A cytological, immunophenotypical and cytogenetical study of 136 consecutive cases of B-cell chronic lymphoid hemopathies].

A cytological, immunophenotypical and cytogenetical study of 136 chronic B-cell proliferations (93 CLL, 43 B-cell lymphomas) was led in order to precise diagnosis and to characterize and appreciate chromosomal rearrangements. In this series, mainly selected on blood lymphocytosis criteria, B-CLL were twice more frequent than small B-cell lymphomas. Probes used revealed cryptic abnormalities, which remained unknown by conventional cytogenetics (CC). The frequency of clonal abnormalities (CC and FISH) was 74.8% for this series, with 74.4% for lymphomas and 75.3% for CLL, mainly of Binet stage A (69 A, 13 B, 1 C, 10 unspecified). Proportion was 88.4% in A stages and 84.6% in B stages. In CLL, 13q14 cryptic deletions and translocations were widely majority, 14q32 translocations and trisomy 12 being predominant in lymphoma series. Interphase FISH study of non-clonal metaphasic abnormalities with locus-specific probes often revealed unrecognised clones.

Multicentre, phase II study evaluating capecitabine monotherapy in patients with anthracycline- and taxane-pretreated metastatic breast cancer.

Treating patients with anthracycline- and taxane-pretreated metastatic breast cancer (MBC) represents a significant challenge to oncologists. The tumour-activated oral fluoropyrimidine, capecitabine, is the only treatment approved for these patients. Our study evaluated the efficacy, safety and impact on quality of life (QOL) of capecitabine in this setting. Patients (n=126) with anthracycline- and taxane-pretreated metastatic breast cancer received capecitabine 1250 mg/m(2) twice daily, days 1-14, followed by a 7-day rest period. Median time to progression was 4.9 months (95% Confidence Interval (CI): 4.0-6.4). Thirty-five patients (28%) achieved an objective response (95% CI: 20-36%), including five (4%) complete responses. Median overall survival was 15.2 months (95% CI: 13.5-19.6 months). Capecitabine demonstrated a favourable safety profile, with a low incidence of treatment-related grade 3/4 adverse events. The most common adverse events were hand-foot syndrome and gastrointestinal effects. QOL assessment showed that capecitabine treatment was associated with an increase in mean Global Health Score. Capecitabine is active, well tolerated and improves the QOL of patients with anthracycline- and taxane-pretreated metastatic breast cancer. Based on the consistently high activity demonstrated in clinical trials, capecitabine has become the reference treatment in this setting.

Tumor necrosis factor alpha release is a major biological event associated with rituximab treatment.

INTRODUCTION: In patients with low-grade non-Hodgkin's lymphoma, rituximab (MabThera) produces infusion-related toxicity, including fever, rigors, and chills in greater than 50% of those treated. The majority of these reactions are grade 1 or 2. MATERIALS AND METHODS: In the GELA study LNH98-5, a total of 400 elderly patients with previously untreated diffuse large B-cell lymphoma were randomized to treatment with CHOP or with rituximab plus CHOP (R-CHOP). In a detailed investigation of biological events which may be associated with adverse reactions specific to rituximab infusion, a subgroup of 55 patients (26 in the CHOP group and 29 in the R-CHOP group) were selected for measurement of several biological parameters at baseline and at 1, 4 and 8 h (H1, H4 and H8, respectively) after commencing therapy. For 27 patients, measurements included cytokine and complement levels. RESULTS: Baseline demographic and disease characteristics were similar for patients in both treatment groups. Compared with the CHOP treatment group, patients in the R-CHOP group had significantly higher post-treatment changes in neutrophil, lymphocyte, and monocyte counts, LDH levels, C3a levels, and TNF-alpha levels. In the R-CHOP group, neutrophil levels increased at H4 (P<0.05), lymphocyte levels decreased at H1 (P<0.05), H4 (P<0.001) and H8 (P<0.05), monocytes levels decreased at H1 (P<0.01), LDH levels increased at H4 (P<0.05) and H8 (P<0.01), and C3a decreased at H1 (P<0.01). The most statistically significant changes were observed for TNF-alpha levels: Mean values of TNF-alpha increased more than 250% at H1 and H4 and were still increased by 170% at H8 (P<0.001 at all timepoints). Since only six of the 55 evaluated patients had severe adverse events, it was not possible to correlate severe toxicity with these biological variations. CONCLUSION: This analysis demonstrates that rituximab infusion was rapidly followed by activation of complement, B-lymphocyte cytolysis, and TNF-alpha release.

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.

First-line high-dose sequential chemotherapy with rG-CSF and repeated blood stem cell transplantation in untreated inflammatory breast cancer: toxicity and response (PEGASE 02 trial).

Despite the generalization of induction chemotherapy and a better outcome for chemosensitive diseases, the prognosis of inflammatory breast cancer (IBC) is still poor. In this work, we evaluate response and toxicity of high-dose sequential chemotherapy with repeated blood stem cell (BSC) transplantation administered as initial treatment in 100 women with non-metastatic IBC. Ninety-five patients (five patients were evaluated as non-eligible) of median age 46 years (range 26-56) received four cycles of chemotherapy associating: cyclophosphamide (C) 6 g m(-2) - doxorubicin (D) 75 mg m(-2) cycle 1, C: 3 g m(-2) - D: 75 mg m(-2) cycle 2, C: 3 g m(-2) - D: 75 mg m(-2) - 5 FU 2500 mg m(-2) cycle 3 and 4. BSC were collected after cycle 1 or 2 and reinfused after cycle 3 and 4. rG-CSF was administered after the four cycles. Mastectomy and radiotherapy were planned after chemotherapy completion. Pathological response was considered as the first end point of this trial. A total of 366 cycles of chemotherapy were administered. Eighty-seven patients completed the four cycles and relative dose intensity was respectively 0.97 (range 0.4-1.04) and 0.96 (range 0.25-1.05) for C and D. Main toxicity was haematological with febrile neutropenia ranging from 26% to 51% of cycles; one death occurred during aplasia. Clinical response rate was 90% +/- 6%. Eighty-six patients underwent mastectomy in a median of 3.5 months (range 3-9) after the first cycle of chemotherapy; pathological complete response rate in breast was 32% +/- 10%. All patients were eligible to receive additional radiotherapy. High-dose chemotherapy with repeated BSC transplantation is feasible with acceptable toxicity in IBC. Pathological response rate is encouraging but has to be confirmed by final outcome.

A placebo-controlled study of recombinant human granulocyte-macrophage colony-stimulating factor administered during and after induction treatment for de novo acute myelogenous leukemia in elderly patients. Groupe Ouest Est Leucémies Aiguës Myéloblastiques (GOELAM).

The complete remission (CR) rate after intensive chemotherapy for acute myelogenous leukemia (AML) remains low in elderly patients, mainly because of a higher infectious mortality rate related to neutropenia and an increased incidence of adverse prognostic factors. Granulocyte-macrophage colony-stimulating factor (GM-CSF) has been shown to potentially recruit leukemic blasts into cell cycle and improve cytotoxic effects when given during chemotherapy, and to shorten the duration of neutropenia when administered after chemotherapy. Two hundred forty patients aged 55 to 75 years who had newly diagnosed AML were randomly assigned to receive placebo or Escherichia coli-derived GM-CSF (5 micrograms/kg/d by 6-hour intravenous infusion) starting during induction chemotherapy on day 1 and continued through and after chemotherapy until recovery of neutrophils, or evidence of regrowth of leukemia, or up to day 28. Induction chemotherapy consisted of idarubicin (8 mg/m2/d on days 1 to 5) and cytarabine (100 mg/m2/d on days 1 to 7). The study drug was not administered subsequent to the induction course. Patients who achieved a CR received continuous maintenance therapy for 1 year with four quarterly reinduction courses; in the 55- to 64-year age subgroup, patients were randomly assigned to receive or not a consolidation course before maintenance therapy. The CR rate was similar in the GM-CSF and placebo groups (63% and 60.5%, respectively; P = .79). The mortality, rate of resistant disease, and rate of regrowth of leukemia were also similar in both groups. The time to neutrophil recovery was shorter in patients who received GM-CSF (24 v 29 days; P = .0001), but the incidence and characteristics of infectious events were not different. The 2-year disease-free survival (DFS) rate was significantly improved in the GM-CSF group (48% v 21% in the placebo group; P = .003). This effect was highly significant in the cohort of patients aged 55 to 64, but only marginal in patients >/=65 years of age. There was a trend toward a longer overall survival (OS) in the GM-CSF group (P = .082). In summary, the administration of GM-CSF, concomitantly with chemotherapy and thereafter during induction course in AML, shortened the time to neutrophil recovery, but did not improve the CR rate in patients aged 55 to 75. Nonetheless, DFS and OS were significantly prolonged in patients aged 55 to 64 treated with GM-CSF. These results are promising and further evaluation of myeloid growth factors in AML is warranted.

Role of the CD34+ 38- cells in posttransplant hematopoietic recovery.

Using three different statistical tests in parallel, we showed in a preliminary study that neither mononuclear cells, CD34+ 33+ or 33- cells, nor CD34+ 38+ cells significantly correlated with engraftment kinetics following autologous blood cell transplantation (ABCT). We additionally demonstrated here, in a series of patients suffering from malignant diseases, that the graft content in CD34+ 38- cells is individually a more sensitive indicator of the earliest, as well as the latest post-ABCT trilineage hematopoietic recovery than the colony-forming units-granulocyte-macrophage and even the total CD34+ cell content. This suggests that the CD34+ 38- cell population is itself subdivided into two more subsets, one being already lineage-committed and responsible for short-term engraftment, the other containing only very primitive hematopoietic cells responsible for sustained engraftment. Strong arguments favor the probability that these subsets correspond to HLA-DR+ and DR cells, respectively. We also defined an optimal threshold value of 0.05 x 10(6) CD34+ 38- cells/kg of the patient's body weight (b.w.) above which a rapid and sustained trilineage engraftment safely occurs. In fact, infusion of lower numbers of cells seems to have a more significant impact on long-term compared to short-term neutrophil recovery and on platelet kinetics engraftment. We additionally looked for the eventual influence on engraftment time of the type of disease, and of post-ABCT administration of hematopoietic growth factors (HGF). When the type of disease appeared to have no influence on the engraftment time, posttransplant HGF administration significantly reduced the time to trilineage engraftment in patients transplanted with < 0.05 x 10(6) CD34+ 38- cells, thus justifying it in case of reinfusion of low numbers of CD34+ 38- cells. On the other hand, the administration of HGF after infusion of more than 0.05 x 10(6) CD34+ 38- cells/kg b.w. did not hasten more, or only very little, the engraftment time, thus becoming not only unprofitable for the patients but costly as well.

Prognostic factors for survival and response after high-dose therapy and autologous stem cell transplantation in systemic AL amyloidosis: a report on 21 patients.

We retrospectively investigated the feasibility and the toxicity of autologous stem cell transplantation (ASCT) in 21 cases of systemic amyloidosis (AL). The conditioning regimens consisted of high-dose melphalan (HDM) alone (n = 18) or in combination with 12 Gy total body irradiation (n = 3). Toxic death rate was high: 9/21 patients (43%) died within the first month following ASCT, and 10/12 surviving patients achieved a response. With a median follow-up of 14 months, the OS and the EFS rates at 4 years were 57.1% (+/-10.8) and 29.9% (+/-14.5) respectively for the whole group. The major prognostic factor for both response and survival was the number of clinical manifestations at the time of ASCT, of the following five criteria, i.e. creatinine clearance < 30 ml/min, nephrotic syndrome with urinary protein excretion > 3000 mg/24 h, congestive heart failure, neuropathy, or hepatomegaly associated with alkaline phosphatase level > 200 IU/l. For patients presenting with two or more clinical manifestations the 4-year OS and EFS were both 11.1% compared with 91.7% and 46.3% respectively in patients with fewer than two clinical manifestations at the time of ACST. We conclude that ASCT is feasible in AL in a subset of patients with fewer than two clinical manifestations at the time of ASCT. Given the severe extra-haematological toxicity, ASCT should not be considered in other cases.

Primordial role of CD34+ 38- cells in early and late trilineage haemopoietic engraftment after autologous blood cell transplantation.

In order to better define which cell subset contained in graft products might be the most predictive of haemopoietic recovery following autologous blood cell transplantation (ABCT), the relationships between the amounts of reinfused mononuclear cells (MNC), CFU-GM, total CD34+ cells and their CD33 and CD38 subsets. and the successive stages of trilineage engraftment kinetics, were studied in 45 cancer patients, using the Spearman correlation test, a linear regression model and a log-inverse model. No relationship was found between the infused numbers of MNC, CD33+ and CD33- subsets observed and the numbers of days to reach predetermined absolute neutrophil (ANC), platelet and reticulocyte counts. The infused numbers of CFU-GM, CD34+ and CD34+ 38+ cells correlated inconstantly with haemopoietic recovery parameters. The strongest and the most constant correlations were significantly observed between the infused numbers of CD34+ 38- cells and each trilineage engraftment parameter. The log-inverse model determined a threshold dose of 0.05 x 10(6) (= 5 x 10(4)) CD34+ 38- cells/kg, below which the trilineage engraftment kinetics were significantly slower and unpredictable. Post-transplant TBI-conditioning regimens increased the low cell dose-related delay of engraftment kinetics whereas post-transplant administration of haemopoietic growth factors (HGF) seemed to abrogate this delay. This would justify clinical use of HGF only in patients transplanted with CD34+ 38- cell amounts lower than the proposed threshold value. This study suggests that the CD34+ 38- subpopulation, although essentially participating in late complete haemopoietic recovery, is also composed of committed progenitor cells involved in early trilineage engraftment.

Subcutaneous interleukin-2, interferon alfa-2a, and continuous infusion of fluorouracil in metastatic renal cell carcinoma: a multicenter phase II trial. Groupe Français d'Immunothérapie.

PURPOSE: A phase II trial was designed to determine the efficacy and the tolerance of interleukin-2 (IL-2), interferon alfa-2a (IFNalpha), and fluorouracil (5-FU) in patients with metastatic renal cell carcinoma. PATIENTS AND METHODS: One hundred eleven patients were included. Patients received subcutaneous IL-2 9 x 10(6) IU daily for 6 days and IFNalpha 6 x 10(6) IU on days 1, 3, and 5 every other week for 8 weeks. 5-FU was administered through a continuous infusion at 600 mg/m2 for 5 consecutive days for 1 week every 4 weeks. RESULTS: The response rate was 1.8% (95% confidence interval [CI], 0% to 4.3%) with only two partial responses (PRs). Toxicity was moderate with 3.6% grade 4 events and two deaths related to treatment. CONCLUSION: This regimen of IL-2, IFNalpha, and 5-FU in patients with metastatic renal cell carcinoma was ineffective. The results raise the question of the dose and schedule of subcutaneous cytokines that must be used in metastatic renal carcinoma.

Comparison of autologous bone marrow transplantation and intensive chemotherapy as postremission therapy in adult acute myeloid leukemia. The Groupe Ouest Est Leucémies Aiguës Myéloblastiques (GOELAM).

Three intensive consolidation strategies are currently proposed to younger adults with acute myeloid leukemia (AML) in first complete remission (CR): allogeneic or autologous bone marrow transplantation (BMT) and intensive consolidation chemotherapy (ICC). Patients aged 15 to 50 years with de novo AML received an induction treatment with 7 days of cytarabine and either idarubicin or rubidazone. After achievement of a CR, patients up to the age of 40 and having an HLA-identical sibling were assigned to undergo an allogeneic BMT. All the other patients received a first course of ICC with high-dose cytarabine and the same anthracycline as for induction. They were then randomly assigned to either receive a second course of ICC with amsacrine and etoposide or a combination of busulfan and cyclosphosphamide followed by an unpurged autologous BMT. Of 517 eligible patients, 367 had a CR, but only 219 (59.5%) actually received the planned intensive postremission treatment (73 allogeneic BMT, 75 autologous BMT, and 71 ICC). With a median follow-up of 62 months, the 4-year disease-free survival (DFS) of the 367 patients in CR was 39.5%. The 4-year overall survival (OS) of the 517 eligible patients was 40.5%. In multivariate analysis, DFS and OS were influenced only by the initial white blood cell count and by the French-American-British classification. The type of postremission therapy had no significant impact on the outcome. There was no difference in the 4-year DFS and OS between 88 patients for whom an allogeneic BMT was scheduled (respectively, 44% and 53%) and 134 patients of the same age category and without an HLA-identical sibling (respectively, 38% and 53%). Similarly, there was no difference in the outcome between autologous BMT and ICC. The 4-year DFS was 44% for the 86 patients randomly assigned to autologous BMT and 40% for the 78 patients assigned to ICC (P = .41). The 4-year OS was similar in the two groups (50% v 54.5%, P = .72). The median duration of hospitalization and thrombocytopenia were longer after autologous BMT (39 v 32 days, P = .006, and 109.5 v 18.5 days, P = .0001, respectively). After a first course of ICC, a second course of chemotherapy is less myelotoxic than an unpurged autologous BMT but yields comparable DFS and OS rates.

Combination of quinine as a potential reversing agent with mitoxantrone and cytarabine for the treatment of acute leukemias: a randomized multicenter study.

A phase III prospective randomized multicenter study was performed to determine whether quinine could improve the response rate of poor-risk acute leukemias (ALs) to standard chemotherapy including a multidrug resistance (MDR)-related cytotoxic agent. The rationale of the study was based on the negative prognostic value of MDR phenotype in ALs and the ability of quinine to reverse this phenotype both in vitro and ex vivo. Three hundred fifteen patients (median age, 49 years; range, 16 to 65) with relapsed (n = 108) or refractory (n = 32) acute myeloblastic leukemia (AML), relapsed (n = 27) or refractory (n = 9) acute lymphoblastic leukemia (ALL), secondary AL (n = 22) or blastic transformation of myelodysplastic syndrome ([MDS] n = 74) or myeloproliferative syndrome ([MPS] n = 43) were randomly assigned to receive mitoxantrone ([MXN] 12 mg/m2/d, days 2 to 5) and cytarabine ([Ara-C] 1 g/m2/12 h, days 1 to 5) alone or in combination with quinine (30 mg/kg/d, days 1 to 5; continuous intravenous infusion beginning 24 hours before MXN infusion). Side effects of quinine were observed in 56 of 161 quinine-treated patients and disappeared in all but four cases after one or two 20% dose decreases. Sera from quinine-treated patients showed increased MXN uptake in an MDR-positive cell line compared with matched sera obtained before quinine infusion. Quinine induced a significant increase in the incidence of nausea, vomiting, mucositis, and cardiac toxicity. A complete response (CR) was observed in 85 of 161 patients (52.8%) from the quinine-treated group versus 70 of 154 patients (45.5%) in the control group (P = .19). The most important differences between quinine and control group CR rates were observed in patients with refractory AMLs and blastic transformation of MDS and MPS. The CR rate was higher in P-glycoprotein-positive cases, although the difference was not significant. Failure of the regimen due to blastic persistence or blast number increase was higher in the control group (61 of 154 patients) than in the quinine group (45 of 161, P = .04). Early death was observed in eight cases (four in each arm) and death in aplasia in 27 cases (20 in quinine group v seven in control group, P = .01). The significant increase of toxicity in the quinine arm could have masked the clinical benefit of MDR reversion in poor-risk ALs.

Treatment of acute myelogenous leukaemia in patients aged 50-65: idarubicin is more effective than zorubicin for remission induction and prolonged disease-free survival can be obtained using a unique consolidation course. The Goelam Group.

From December 1987 to June 1992, 251 patients aged 50-65 with de novo acute myelogenous leukaemia (AML) were recruited to a multi-institutional randomized clinical trial. Induction therapy consisted of Ara-C (200 mg/ m2, continuous infusion, days 1-7) with either zorubicin (ZRB) (200 mg/m2, i.v., days 1-4) or idarubicin (IDR) (8 mg/ m2, i.v., days 1-5). Consolidation therapy consisted of a single course of intensive chemotherapy with high-dose Ara-C (3 g/m2, 3 h infusion, q 12 h, days 1-4) and m-Amsa (100 mg/m2/d, i.v., days 5-7). The complete remission (CR) rate was (73%) with Ara-C/ IDR versus (60%) with Ara-C/ZRB (P = 0.033). In multivariate analysis, factors found to be significant in predicting CR were normal karyotype and treatment with IDR. With a median follow-up of 73 months, the median disease-free survival (DFS) duration of all CR patients and the probability of CR at 6 years were 17 months and 29%. In multivariate analysis the only factor associated with an increased DFS duration was a normal karyotype. The median event-free survival (EFS) duration for all evaluable patients and the median overall survival duration for all eligible patients were respectively 7 and 12 months without any difference between induction arms. The study shows that in patients aged 50-65 idarabicin is more effective than zorubicin for remission induction. However, the type of anthracycline did not influence overall survival duration. Using a unique consolidation course, we observed a prolonged DFS which compares favourably with results obtained with more prolonged consolidation therapy or maintenance treatment.

5-Fluorouracil versus 5-fluorouracil plus alpha-interferon as treatment of metastatic colorectal carcinoma. A randomized study.

BACKGROUND: In 1989, S. Wadler reported very promising results (76% response rate) with a combination of 5-fluorouracil (5-FU) plus alpha-2a interferon (IFN) in the treatment of metastatic colorectal carcinoma (MCRC). In vitro, there are several potential explanations for synergism between the two agents. We therefore decided in 1989 to start a randomized study comparing 5-FU alone with 5-FU plus IFN. PATIENTS AND METHODS: 105 non-pretreated patients with measurable metastatic colorectal carcinoma entered into this study. The patients were randomly allocated either in arm A (n = 49) with 5-FU: 750 mg/m2 i.v. CI d1-d5 followed by 750 mg/m2 i.v. bolus once a week, or in arm B (n = 56) with 5-FU as in arm A plus IFN 9 x 10(6) IU sub-cutaneously three times a week. RESULTS: After two months of treatment we observed 1 CR and 2 PR in arm A (response rate 6.1%), 3 CR and 8 PR in arm B (response rate 19.6%), i.e., a significant difference (P = 0.05). Event-free survival was significantly higher in arm B (6 months) than in arm A (2 months) (P < 0.01), while median survival was slightly higher in arm B (12 months) than in arm A (10 months) (P < 0.05). For overall survival the difference was not significant after adjustment on center treatment and baseline Karnofsky status (P = 0.13). Toxicity was also greater in arm B. Sixteen percent of patients in arm A and 36% in arm B experienced certain grade 3-4 side effects (P < 0.05). CONCLUSION: 5-FU plus IFN is more effective than 5-FU alone in terms of response rate, event free survival but not of overall survival. 5-FU plus IFN is more toxic. As IFN has no demonstrated efficacy in MCRC as a single agent, this study suggests that IFN is acting as a 5-FU modulatory agent. The response rate observed (19.6%) is similar to the results obtained elsewhere with 5-FU plus leucovorin.

Is the small non-cleaved-cell lymphoma histologic subtype a poor prognostic factor in adult patients? A case-controlled analysis. The Groupe d'Etude des Lymphomes de l'Adulte.

PURPOSE: To study the prognostic significance of the small non-cleaved-cell lymphoma (SNCCL) histologic subtype, we compared the outcome of adult patients with SNCCL with that of patients with aggressive lymphoma other than SNCCL by means of two case-controlled studies. PATIENTS AND METHODS: We analyzed the results of the doxorubicin, cyclophosphamide, vindesine, bleomycin, and prednisone (ACVBP) regimen used as a reference scheme in our cooperative study group (Groupe d'Etude des Lymphomes de l'Adult [GELA]) in 52 adult SNCCL patients with no bone marrow (BM) or CNS involvement. Forty-five SNCCL patients younger than 60 years could be compared with two separate case-matched groups of patients with aggressive lymphoma other than SNCCL undergoing the same therapeutic regimen. In the first case-controlled study, matching ensured identity of each risk factor of the age-adjusted International Index (ie, Ann Arbor stage, performance status, and lactate dehydrogenase [LDH] level); in the second study, matching was performed according to the number of presenting risk factors (zero, one, two, or three), regardless of their nature. RESULTS: The 5-year overall survival rates were not significantly different between SNCCL and control patients in both case-controlled studies: 48% versus 51% in the first study, and 48% versus 55% in the second study. CONCLUSION: These results support the thesis that in patients with no bone marrow or CNS involvement, the SNCCL histologic subtype does not confer a prognosis worse than that of other aggressive lymphoma.

Idarubicin and high dose cytarabine: a new salvage treatment for refractory or relapsing non-Hodgkin's lymphoma.

Twenty three patients with relapsing (n = 11) or refractory (n = 12) non-Hodgkin's lymphoma (NHL) to one or two prior anthracycline based combination chemotherapy regimens were treated as second or third line regimen with 3 induction cycles of Idarubicin (IDA) (7 mg/m2/d i.v. d1-d3) and high dose cytarabine (HD Ara-C) (1 g/m2/12 h i.v. d1-d3), each cycle was repeated every 3 weeks. Responding patients received a maintenance therapy with monthly cycles of IDA: 15 mg/m2 d1-d3, Etoposide 100 mg/m2 d1-d3, both by oral route. Twenty two patients are evaluable and we observed 13 CR and 1 PR with an overall response rate of 61% (14/23: 95% Cl = 38.5% 80.3%). The median time to progression was 32 months (6.5 - 63 + m.). The response rate to IDA-HD Ara C was not different for patients with (n = 14) or without (n = 9) objective response to the last prior therapy. The main toxicity was hematological: all patients experienced grade 4 neutropenia and 22 patients had grade 4 thrombopenia, but there were no toxic deaths. IDA and HD-Ara-C combination is highly effective in refractory or relapsed. NHL. As hematological toxicity was the limiting factor for further escalation of dose-intensity, further studies might include hematopoietic growth factors support in the therapeutic scheme.

[Carboplatin and cyclophosphamide in stage Ic-IV ovarian carcinoma: retrospective study of 101 cases].

We report our experience of CBDCA-CPM combination chemotherapy as first line therapy in 101 ovarian cancers. The therapeutic scheme was: initial cytoreductive surgery followed by six chemotherapy cycles (CBDCA 400 mg/m2/d IV dl, CPM 600 mg/m2/d IV dl, dl = d21) and second-look laparotomy. The initial stages were four Ic, three IIa, four IIb, four IIc, 15 IIIa, 28 IIIb, 23 IIIc and 20 IV. After initial surgery, there were 39 macroscopic residual diseases superior to 2 cm, 26 macroscopic residual diseases inferior or equal to 2 cm, four microscopic diseases and no residual disease in 30 cases (unknown in two cases). The overall response rate to chemotherapy was 83% with 56% histologic complete response rate. The main toxicity was haematological with 60% of leucopenia grade III-IV, 52% of thrombopenia grade III-IV. Age at diagnosis, residual disease after first look surgery and length of CA 125 normalization were significant prognostic factors for survival in this series.

[AIDS-related eosinophilic folliculitis. Efficacy of high dose topical corticotherapy].

INTRODUCTION: A chronic pruriginous eruption of eosinophil-rich follicular papules and pustules is observed in AIDS patients. The pathogenesis of this disease, termed eosinophil folliculitis, is poorly understood and treatment is debated. CASE REPORT: A 30-year-old woman with AIDS developed highly pruriginous lesions of 5 month duration localized on the face, the trunk and upper limbs. There were papulo-pustules and excoriated papules. The elementary lesion was a follicular pustula. The eosinophil count was normal. The pathology examination revealed a rich eosinophil infiltration around the hair follicles and sebaceous glands as well as follicular spongiosis. Search for demodex, pityrosporons and a large number of infectious agents was negative. Oral minocyclin was uneffective. Local high-dose corticosteroids produced a remarkable effect and led to complete remission in 9 months. DISCUSSION: Most cases of eosinophil folliculitis associated with AIDS have been reported in men, but rarely in Europe. The remarkable efficacy of the local corticosteroid in this case was exceptional. This condition could result from inappropriate inflammatory reaction in AIDS induced by various factors including demodex and pityrosporon. Several therapeutic approaches have been proposed to eradicate the triggering factors and others to modify the immune response. The exceptional response to the short local treatment with corticosteroids would suggest that this approach could be proposed as first intention treatment in eosinophil folliculitis associated with AIDS.
