Abstract
The rate of long-term remissions after treatment of peripheral T cell lymphomas (PTCL) with standard CHOP-like protocols is unsatisfactory. A prospective multicenter phase II trial was initiated in untreated patients with PTCL of all International Prognostic Index-risk groups, evaluating alemtuzumab consolidation in patients with complete or good partial remission after CHO(E)P-14 induction. Twenty-nine (70.7 %) of the 41 enrolled patients received alemtuzumab consolidation (133 mg in total). The main grades 3–4 toxicities during alemtuzumab therapy were infections and neutropenia with one potentially treatment-related death. Complete responses were seen in 58.5 %, partial responses in 2.4 % and 29.3 % had progressive disease. After a median observation time of 46 months, 19 patients have died, 16 of them due to lymphoma and/or salvage therapy complications. Event-free and overall survival at 3 years in the whole intent to treat population are 32.3 and 62.5 %, respectively, and 42.4 and 75.1 % in the patients who received alemtuzumab. In conclusion, application of a short course of alemtuzumab after CHO(E)P-14 induction is feasible although complicated by severe infections. A current phase III trial, applying alemtuzumab as part of the initial chemotherapy protocol to avoid early progression, will further clarify its significance for the therapeutic outcome.

Abstract
Lymphoplasmacytic lymphoma (LPL) is an indolent lymphoma with moderate sensitivity to conventional chemotherapy. This study investigated whether the addition of rituximab to standard chemotherapy improves treatment outcome in LPL and the subgroup of LPL patients fulfilling the criteria of Waldenstroem's macroglobulinemia (WM). A total of 69 patients with previously untreated LPL were enrolled into the trial; 64 patients were evaluable for treatment outcome. In all, 48 of the 64 LPL patients fulfilled the criteria of WM. Patients were randomly assigned to R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone, n=34) or CHOP (n=30). R-CHOP resulted in significantly higher overall response (OR) rate (94 vs 67%, P=0.0085) in the LPL patients and in the WM subgroup (91 vs 60%, P=0.0188). With a median observation time of 42 months, R-CHOP induced a significantly longer time to treatment failure (TTF) with a median of 63 months for R-CHOP vs 22 months in the CHOP arm in the LPL patients (P=0.0033) and in the WM subgroup (P=0.0241). There was no major difference of treatment-associated toxicity between both treatment groups. These data indicate that the addition of rituximab to front-line chemotherapy improves treatment outcome in patients with LPL or WM.

Abstract
7538 Background: The clinical course of peripheral T-cell lymphomas (PTCL) is unfavourable. Treatment protocols developed for aggressive B-NHL are employed, with significantly worse outcomes. The MoAb alemtuzumab (CAM) has shown promising activity in T-NHL, although its use may be complicated by severe infections. Methods: In 2003, the DSHNHL group initiated a prospective multicenter phase II trial for previously untreated PTCL. Six cycles of either CHOEP-14 (< 60 y) or CHOP-14 (> 60 y) with G-CSF support are followed by a short consolidation course with CAM, when either a CR or a good PR has been achieved. Inclusion criteria: PTCL-NOS, AILD, intestinal T-NHL, anaplastic large cell T-NHL (ALK negative); age 18–70 y; all IPIs; ECOG PS 0–3. The primary endpoint is feasibility, measured by occurrence SAE and protocol adherence. Secondary endpoints are remission rate, TTF, OS, DFS, tumor control and TRM. CAM is given at a total dose of 133 mg over 4 weeks. Prophylaxis against PCP and herpes infections is mandatory during CAM therapy and is continued until CD 4 cells are > 200/μl. CMV-positive patients are monitored weekly. Results: 35 (of the planned 37) pts have been enrolled, 31 are evaluable. 5/31 pts are still undergoing chemotherapy. 7/31 pts had progressive disease or NC under/after chemotherapy and did not receive CAM. 18 of the 19 pts who achieved a CR/PR (15/4) received CAM. 12 of the CAM pts are in continuous CR, 7 had progressive disease or relapsed. There was no treatment-related death. Of 7 registered SAEs, 3 were related to chemotherapy, 4 to CAM (1 fungal pneumonia, 2 CMV pneumonias, 1 bacterial sepsis after dental procedure). Other CAM side effects were: Herpes Zoster (1), CMV-reactivation (1), grade III-IV neutropenias (2). All pts recovered with appropriate treatment. Conclusion: Preliminary analysis demonstrates that the combination of CHO/E/P-14 followed by a short course of CAM consolidation therapy is feasible without TRM. The adverse effects related to infections can be severe but manageable upon careful monitoring and close follow-up. The phase II trial will close in 4/2006, to be followed by a randomized phase III trial of A-CHOP-14 vs CHOP-14. No significant financial relationships to disclose.

Abstract
Immunosuppression has recently been proposed for low-risk myelodysplastic syndromes (MDS) to reverse bone marrow failure by inhibiting intramedullary secretion of proapoptotic cytokines. We treated 35 MDS patients (24 refractory anaemia (RA), 10 RA with excess blasts and one chronic myelomonocytic leukaemia) with either horse antithymocyte globulin 15 mg/kg/day or rabbit antithymocyte globulin 3.75 mg/kg/day, each for 5 days. Median age was 63 years (range: 41-75). After 1 to 34+ months of follow-up (mean: 15+), four patients experienced complete haematological responses (CR), six good responses (GR) and two minor responses. All CRs and GRs occurred in patients with RA, in whom both horse and rabbit ATG yielded five responses out of 12 (42%). Time to response varied between 1 and 10 (mean: 3) months. The median duration of response was 9+ (1-17+) months; five patients are in continuing response. In all, 23 patients suffered side effects > degrees II WHO (the degree of toxicity encountered according to the internationally accepted WHO toxicity grading); one patient died 2 weeks after rabbit ATG from rhinocerebral mucormycosis. Parameters that correlated with response were duration of disease and RA subgroup. In our experience, immune-modulating therapy with either horse or rabbit ATG is feasible in patients with RA and short duration of disease.

Abstract
The optimum treatment conditions of interferon (IFN) alpha therapy in chronic myeloid leukemia (CML) are still controversial. To evaluate the role of hydroxyurea (HU) for the outcome of IFN therapy, we conducted a randomized trial to compare the combination of IFN and HU vs HU monotherapy (CML-study II). From February 1991 to December 1994, 376 patients with newly diagnosed CML in chronic phase were randomized. In all, 340 patients were Ph/BCR-ABL positive and evaluable. Randomization was unbalanced 1:2 in favor of the combination therapy, since study conditions were identical to the previous CML-study I and it had been planned in advance to add the HU patients of study I (n=194) to the HU control group. Therefore, a total of 534 patients were evaluable (226 patients with IFN/HU and 308 patients with HU). Analyses were according to intention-to-treat. Median observation time of nontransplanted living patients was 7.6 years (7.9 years for IFN/HU and 7.3 years for HU). The risk profile (new CML score) was available for 532 patients: 200 patients (38%) were low, 239 patients (45%) intermediate, and 93 patients (17%) high risk. Complete hematologic response rates were higher in IFN/HU-treated patients (59 vs 32%). Of 169 evaluable IFN/HU-treated patients (75%), 104 patients (62%) achieved a cytogenetic response that was complete in 12% (n=21), major in 14% (n=24), and at least minimal in 35% (n=59). Of the 534 patients, 105 (20%) underwent allogeneic stem cell transplantation in first chronic phase. In the low-risk group, 65 of 200 patients were transplanted (33%), 30 (13%) in the intermediate-risk group, and nine (10%) in the high-risk group. Duration of chronic phase was 55 months for IFN/HU and 41 months for HU (P<0.0001). Median survival was 64 months for IFN/HU and 53 months for HU-treated patients (P=0.0063). We conclude that IFN in combination with HU achieves a significant long-term survival advantage over HU monotherapy. In view of the data of CML-study I, these results suggest that IFN/HU is also superior to IFN alone. HU should be combined with IFN in IFN-based therapies and for comparisons with new therapies.

Abstract
Intensive induction therapy in acute myeloid leukemia (AML) as in some other systemic malignancies is a strategy fundamentally different from post-remission strategies. Approaches such as consolidation treatment, prolonged maintenance, and autologous or allogeneic transplantation in first remission are directed against the minimal residual disease in which a malignant cell population has survived induction treatment and shows resistance due to special genetic or kinetic features. In contrast, induction therapy deals with naive tumor cells possibly different from their counterparts in remission in terms of their kinetic status and sensitivity. Therefore, in AML the introduction of intensification strategies into the induction phase of treatment has been suggested as a new step in addition to intensification in the postremission phase. As expected from the dose effects observed in post-remission treatment with high-dose cytarabine (AraC) or longer treatment, similar dose effects have been found in induction treatment both from the incorporation of high-dose AraC and from the double-induction strategy used in patients up to 60 years of age. As a particular effect, patients with poor-risk AML according to an unfavorable karyotype, high LDH in serum, or a delayed response show longer survival following double induction containing high-dose AraC as compared to standard-dose AraC. A corresponding dose effect in the induction treatment of patients aged 60 years and older has been found with daunorubicin 60 vs 30 mg/m2 as part of the thioguanine/ AraC/daunorubicin (TAD) regimen with the higher dosage significantly increasing the response rate and survival in these older patients who represent a poor-risk group as a whole. Thus we have been able to demonstrate both in younger and older patients that a poor prognosis can be improved by a more intensive induction therapy. High-dose AraC in induction, however, exhibits cumulative toxicity in that repeated courses containing high-dose AraC in the post-remission period lead to long-lasting aplasias of about 6 weeks. Thus after intensive induction treatment, high-dose chemotherapy in remission may be practicable using stem-cell rescue and may contribute to a further improvement in the outcome in poor-risk as well as average-risk patients with AML. These approaches are currently under investigation by the German AML Cooperative Group (AMLCG). "The more intensive the better" is certainly not the way to go in the management of AML and other systemic malignancies but some increase in intensity may be possible and better.

Abstract
Natural killer (NK) cell lymphomas are a newly recognized entity of non-Hodgkin's lymphoma with a highly aggressive clinical course and strong association with Epstein-Barr virus (EBV) infection. Although no recurrent chromosome aberrations have been identified in NK-cell lymphoma, deletions of 6q and trisomy 7 have been described repeatedly in this type of lymphoma. In this study we attempted to determine the immunophenotypes of tumour cells with certain chromosome aberrations, i.e. deletions of 6q and trisomy 7, in three cases of NK cell lymphomas by means of combined immunophenotyping and fluorescence in situ hybridization (FISH). In all three cases clonal chromosome aberrations were detected only in CD56+ cells but not in CD3+ or CD5+ cells. However, not all CD56+ cells were shown to contain these chromosome aberrations. Double immunophenotyping combined with FISH confirmed that the chromosome aberrations occurred only in CD56+CD3- cells. This study indicates that chromosome aberrations in NK-cell lymphomas are restricted to the CD56+, CD3- and CD5- cell population and that NK-cell lymphomas are indeed derived from mature true NK cells and not from T lymphocytes.

Abstract
Patients with primary refractory or relapsed acute myeloid leukemia (AML) who undergo intensive salvage chemotherapy carry a high risk of treatment failure due to infectious complications and early relapses. The study presented here assessed the effect of granulocyte colony-stimulating factor (G-CSF) on the duration of post-treatment neutropenia, the incidence of infection-related deaths, and the disease-free and overall survival. Sixty-eight evaluable patients with relapsed and refractory AML received G-CSF 5 microg/kg per day subcutaneously starting 2 days after the completion of salvage treatment with the S-HAM regimen, consisting of high-dose cytosine arabinoside twice daily on days 1, 2, 8, and 9 and mitoxantrone on days 3, 4, 10, and 11. Ninety-one patients who were treated with the identical S-HAM regimen but without G-CSF support during a preceding study served as controls. The application of G-CSF resulted in a significant shortening of critical neutropenia of less than 500 microl (36 vs. 40 days; p = 0.008), which translated into a trend towards a lower early death rate (21% vs. 30%) and an increase of complete remissions (56% vs. 47%, p=0.11). In patients younger than 60 years a significant prolongation of time to treatment failure (159 vs. 93 days, p=0.038) and of duration of disease-free survival (203 vs. 97 days, p=0.003) was observed. These results indicate a beneficial effect of G-CSF on early mortality as well as on long-term outcome when administered after S-HAM salvage therapy for advanced AML.

Abstract
BACKGROUND Invasive fungal infections have increasingly become a matter of concern with regard to patients receiving intensive myelosuppressive therapy for hematologic malignancies. Such infections, especially prolonged neutropenia systemic fungal infections, may contribute substantially to infectious complications and early death. Measures for early detection and effective prophylactic strategies using active and nontoxic antifungal agents are therefore urgently needed. METHODS The current randomized study was initiated to assess the efficacy of oral fluconazole as systemic antifungal prophylaxis for high risk patients with recurrent acute myeloid leukemia undergoing intensive salvage therapy. RESULTS Of 68 fully evaluable patients, 36 were randomized to fluconazole in addition to standard prophylaxis with oral co-trimoxazol, colistin sulphate, and amphotericin B suspension, and 32 were randomized to standard prophylaxis only. No major differences between the two groups were observed in the number of episodes of fever of unknown origin (61% vs. 50%) or clinically defined infections (56% vs. 50%). Microbiologically defined infections were more frequent in the fluconazole group (50% vs. 31%), mainly due to a higher incidence of bacteremias (42% vs. 22%). There were two cases of proven invasive fungal infections in each group. Systemic amphotericin B was administered more frequently to patients receiving fluconazole prophylaxis (56% vs. 28%). Fluconazole prophylaxis had no impact on the rate of early death or overall survival. CONCLUSIONS For patients with high risk recurrent acute myeloid leukemia undergoing intensive salvage therapy, antifungal prophylaxis with fluconazole was not superior to standard prophylaxis only.

Abstract
It is the long-term goal of the German CML Study Group and of the Süddeutsche Hämoblastosegruppe (SHG) to improve survival of patients with chronic myelogenous leukemia (CML). In a first randomized study (CML Study I) monotherapies with hydroxyurea or interferon alpha (IFN-alpha) were compared with a standard busulfan regimen with regard to duration of the chronic phase and survival. The main results of this study were published, 1-3 and a long-term follow up is planned. In a second randomized study the effect of the combination of IFN-alpha and hydroxyurea versus hydroxyurea monotherapy on survival is being investigated. This paper provides a first preliminary report on the study concept, patient recruitment, state of documentation and initial patients' characteristics 9 months after closure of the study.

Abstract
The current study was initiated to compare the anti-lymphoma activity and side-effects of prednimustine/mitoxantrone (PmM) vs cyclophosphamide, vincristine, prednisone (COP) in patients with advanced low-grade non-Hodgkin's lymphomas in way of a prospective randomized multicenter trial. Two hundred and forty-six patients with stage III or IV centroblastic-centrocytic (CB-CC (Kiel-classification)) or follicle center lymphoma (FCL (REAL classification)) and centrocytic (CC) or mantle-cell-lymphoma (MCL) were randomized for therapy with either PmM or COP and are fully evaluable for response and toxicity. PmM consisted of prednimustine 100 mg/m2/day on days 1-5 and mitoxantrone 8 mg/m2 /day days 1 and 2, while COP comprised cyclophosphamide 400 mg/m2/day on days 1-5, vincristine 1.4 mg/m2/day on day 1 and prednisone 100 mg/m2/day on days 1-5. Both regimens were repeated for a total of six cycles followed by an additional two courses for consolidation in responding cases and a subsequent second randomization for interferon alpha maintenance vs observation only. Overall response rates were comparable with 83% complete and partial remissions after COP and 84% remissions after PmM. PmM revealed a significantly higher rate of complete remissions (36 vs 18%, P < 0.006), the majority being achieved after four courses. The more rapid and possibly also more effective reduction of the lymphoma cell mass by PmM resulted in a tendency to a longer event-free interval for patients achieving remissions after PmM as compared to COP with estimated median event-free intervals of 31 vs 14 months, respectively (P=0.04). Separate analysis of lymphoma subtypes showed a tendency to a lower rate of complete remission in CC or MCL as compared to CB-CC or FCL (16 vs 30%, P=0.12, NS) while overall response rates were in a similar range (81 vs 85%). In both subtypes, PmM induced a higher rate of complete remission while overall response rates were comparable after PmM or COP. Treatment associated side-effects comprised predominantly myelosuppression and granulocytopenia in particular which was more frequently observed after PmM than COP (43 vs 31 %, P < 0.0001). This difference was clinically irrelevant, however, since serious infectious complications were encountered in less than 3% of cycles after both regimens. COP therapy was associated with a significantly higher incidence and degree of hair loss and complete alopecia (31 vs 2%) as well as of peripheral neurotoxicity (23 vs 2%). These data show that both PmM and COP reveal a high anti-lymphoma activity in patients with advanced stage non-Hodgkin's lymphoma. PmM appears advantageous with a higher rate of complete remissions and a better tolerability with regard to secondary side-effects. A longer follow-up is needed to assess the long-term effects of initial treatment on disease-free and overall survival and the impact on additional maintenance therapy with interferon alpha.

Abstract
Carcinoembryonic antigen (CEA) was determined serially in 54 patients with malignant tumour (other than colorectal ones). Patients in remission (21), those resistant to treatment (16) and a group not receiving treatment (17) showed a good correlation between growth behaviour of the tumour and titre changes. Best correlation was in 21 patients who after treatment with cytostatic agents, hormones or radiation had objective signs of remission. Serial determination of CEA is thus of value in the control of treatment of malignant tumours other than those of the colorectum.

Abstract
Carcinoembryonic antigen (CEA) was assayed in 18 samples of non-malignant and 21 samples of malignant effusions. In 95% of benign effusion CEA activity was found within normal limits and increased only in one case of Klebsiella pneumonia. In 57% of the 21 malignant effusions CEA levels were elevated and in 4 cases elevated titers were first indications of the malignancy of the effusion. In some cases remarkable differences between serum titer and effusion titer were found. Combined measurement of CEA activity in plasma and effusion increases diagnostic value.
