Abstract
BACKGROUND Pancreatic ductal adenocarcinoma (PDAC) is one of the most common malignant tumours and is still associated with a poor prognosis in advanced disease. To improve the standard therapy with gemcitabine, we initiated a prospective randomised phase-II trial with gemcitabine (GEM) versus gemcitabine plus sunitinib (SUNGEM) based on data of in vitro trials and phase-I data for the combination treatment. The rational of adding sunitinib was its putative antiangiogenic mechanism of action. METHODS A total of 106 eligible patients with locally advanced, unresectable or metastatic PDAC without previous system therapy were randomised to receive GEM at a dosage of 1.000mg/m(2) d1, 8, 15 q28 versus a combination of SUNGEM at a dosage of GEM 1.000mg/m(2) d1+8 and sunitinib 50mg p.o. d1-14, q21d. The primary end-point was progression free survival (PFS), secondary end-points were overall survival (OS), toxicity and overall response rate (ORR). RESULTS The confirmatory analysis of PFS was based on the intend-to-treat (ITT) population (N=106). The median PFS was 13.3 weeks (95% confidence interval (95%-CI): 10.4-18.1 weeks) for GEM and 11.6 weeks for SUNGEM (95%-CI: 7.0-18.0 weeks; p=0.78 one-sided log-rank). The ORR was 6.1% (95%-CI: 0.7-20.2%) for GEM and for 7.1% (95%-CI: 0.9-23.5%) for SUNGEM (p=0.87). The median time to progression (TTP) was 14.0 weeks (95%-CI: 12.4-22.3 weeks) for GEM and 18.0 weeks (95%-CI: 11.3-19.3 weeks) for SUNGEM (p=0.60; two-sided log-rank). The median OS was 36.7 weeks (95%-CI: 20.6-49.0 weeks) for the GEM arm and 30.4 weeks (95%-CI: 18.1-37.6 weeks) for the SUNGEM (p=0.78, one-sided log-rank). In regard to toxicities, suspected SAEs were reported in 53.7% in the GEM arm and 71.2% in the SUNGEM arm. Grade 3 and 4 neutropenia was statistically significantly higher in the SUNGEM arm with 48.1% versus 27.8% in the GEM arm (p=0.045, two sided log-rank). CONCLUSIONS The combination SUNGEM was not sufficient superior in locally advanced or metastatic PDAC compared to GEM alone in regard to efficacy but was associated with more toxicity.

Abstract
BACKGROUND Fluorouracil-based chemoradiotherapy is regarded as a standard perioperative treatment in locally advanced rectal cancer. We investigated the efficacy and safety of substituting fluorouracil with the oral prodrug capecitabine. METHODS This randomised, open-label, multicentre, non-inferiority, phase 3 trial began in March, 2002, as an adjuvant trial comparing capecitabine-based chemoradiotherapy with fluorouracil-based chemoradiotherapy, in patients aged 18 years or older with pathological stage II-III locally advanced rectal cancer from 35 German institutions. Patients in the capecitabine group were scheduled to receive two cycles of capecitabine (2500 mg/m(2) days 1-14, repeated day 22), followed by chemoradiotherapy (50·4 Gy plus capecitabine 1650 mg/m(2) days 1-38), then three cycles of capecitabine. Patients in the fluorouracil group received two cycles of bolus fluorouracil (500 mg/m(2) days 1-5, repeated day 29), followed by chemoradiotherapy (50·4 Gy plus infusional fluorouracil 225 mg/m(2) daily), then two cycles of bolus fluorouracil. The protocol was amended in March, 2005, to allow a neoadjuvant cohort in which patients in the capecitabine group received chemoradiotherapy (50·4 Gy plus capecitabine 1650 mg/m(2) daily) followed by radical surgery and five cycles of capecitabine (2500 mg/m(2) per day for 14 days) and patients in the fluorouracil group received chemoradiotherapy (50·4 Gy plus infusional fluorouracil 1000 mg/m(2) days 1-5 and 29-33) followed by radical surgery and four cycles of bolus fluorouracil (500 mg/m(2) for 5 days). Patients were randomly assigned to treatment group in a 1:1 ratio using permuted blocks, with stratification by centre and tumour stage. The primary endpoint was overall survival; analyses were done based on all patients with post-randomisation data. Non-inferiority of capecitabine in terms of 5-year overall survival was tested with a 12·5% margin. This trial is registered with ClinicalTrials.gov, number NCT01500993. FINDINGS Between March, 2002, and December, 2007, 401 patients were randomly allocated; 392 patients were evaluable (197 in the capecitabine group, 195 in the fluorouracil group), with a median follow-up of 52 months (IQR 41-72). 5-year overall survival in the capecitabine group was non-inferior to that in the fluorouracil group (76% [95% CI 67-82] vs 67% [58-74]; p=0·0004; post-hoc test for superiority p=0·05). 3-year disease-free survival was 75% (95% CI 68-81) in the capecitabine group and 67% (59-73) in the fluorouracil group (p=0·07). Similar numbers of patients had local recurrences in each group (12 [6%] in the capecitabine group vs 14 [7%] in the fluorouracil group, p=0·67), but fewer patients developed distant metastases in the capecitabine group (37 [19%] vs 54 [28%]; p=0·04). Diarrhoea was the most common adverse event in both groups (any grade: 104 [53%] patients in the capecitabine group vs 85 [44%] in the fluorouracil group; grade 3-4: 17 [9%] vs four [2%]). Patients in the capecitabine group had more hand-foot skin reactions (62 [31%] any grade, four [2%] grade 3-4 vs three [2%] any grade, no grade 3-4), fatigue (55 [28%] any grade, no grade 3-4 vs 29 [15%], two [1%] grade 3-4), and proctitis (31 [16%] any grade, one [<1%] grade 3-4 vs ten [5%], one [<1%] grade 3-4) than did those in the fluorouracil group, whereas leucopenia was more frequent with fluorouracil than with capecitabine (68 [35%] any grade, 16 [8%] grade 3-4 vs 50 [25%] any grade, three [2%] grade 3-4). INTERPRETATION Capecitabine could replace fluorouracil in adjuvant or neoadjuvant chemoradiotherapy regimens for patients with locally advanced rectal cancer.

Abstract
Bleomycin is generally used as an antineoplastic drug for the intravenous treatment of germ cell tumors or lymphomas. Due to its toxic effect on epithelial cells bleomycin is also used for the treatment of malignant pleural or pericardial effusions. Inadvertent intrathecal administration of cytotoxic drugs may occur due to increasingly complex therapeutic protocols, even when control mechanisms are applied. We report the case of a 39-year-old man with chronic myeloid leukemia. During the treatment of a lymphoblast crisis 30 mg of bleomycin were inadvertently injected intrathecally. Prompt cerebrospinal fluid exchange, dilution with normal saline, and corticosteroid treatment resulted in a positive outcome without major side effects.

Abstract
Methothrexate (MTX) causes unwanted adverse events by affecting gastrointestinal and bone marrow cells when used as an immunosuppressant. Our aim was to reduce those side effects by covalent binding of methothrexate to human serum albumin (HSA) targeting rapidly proliferating lymphocytes, which are known to ingest albumin as an energy source. Twenty-one rats received a kidney transplant. Group A (n = 5) received standard immunosupression (free MTX); group B (n = 9), albumin-MTX conjugates; and group C (n = 7) albumin control. The primary endpoint of this animal study was transplant survival, which was evaluated as death due to uremia. The study was terminated on day 100. Placebo-treated rat recipients (group C) rejected their grafts at a median of 8 days, which was prolonged to 17 days in standard immunosuppressed rats (group A), resulting in doubling transplant survival compared to nonimmunosuppressed animals. However, the same dose given as HSA-conjugated MTX prolonged the median survival time to 43 days. (group B). Hence, the administration of conjugated methotrexate appeared to result in a doubling of transplant survival compared with standard immunosuppression. Moreover, two animals receiving MTX-HSA became long-term survivors without additional immunosuppression. Further studies should be performed to evaluate the significance of these findings in larger animals and possibly in clinical studies.

Abstract
CASE REPORT A 45-year-old patient with cervix carcinoma received combined radiochemotherapy including cisplatin. After a cumulative dose of 240 mg/m(2) the patient suddenly became somnolent and developed a severe tetraparesis and generalized seizures. After ruling out intracranial bleeding, cerebral metastases as well as infectious and metabolic causes of this condition, a severe toxic encephalopathy was diagnosed based on the clinical findings and MRI scans. After symptomatic treatment on the intensive care unit all symptoms were completely reversible. CONCLUSION Toxic encephalopathy is a rare but dramatic complication of various cytostatic drugs. With the widespread use of cisplatin this rare disorder should be kept in mind.

Abstract
4573 Background: The induction of EGFR targeting with cetuximab in radiation based therapy of solid tumors has yielded promising results. Thus, we initiated a prospective phase II trial designed to analyze the feasibility and effectivity of trimodal therapy with gemcitabine-based chemoradiation and cetuximab in locally advanced inoperable pancreatic cancer. Methods: In this phase 2 study, pts with locally advanced pancreatic cancer without prior cytotoxic therapy were treated with radiotherapy (RT), gemcitabine weekly (300mg/m2), and cetuximab weekly (loading dose 400mg/m2 day 1, and concomitant with radiation day 8,15,22,29,36 250mg/m2). RT was delivered by using an integrated IMRT boost concept (54 Gy GTV, 45 Gy CTV) over 5 weeks. RT was followed by gemcitabine (1,000mg/m2) weekly x 3 in 4 weeks. Response evaluation using CT followed at week 12. All pts were intended for surgical treatment between week 12–15. Pts were followed for adverse events and response. Results: 55 pts were enrolled. Preliminary results are presented on 36 pts with the following characteristics: pancreatic adenocarcinoma c2 T4 N1 36/36, median age = 61.5 (range 48–79); M/F = 24/12; ECOG PS 0/1/2 = 6/26/4; median days on treatment: 90 (range 70–100). Treatment-related toxicities were observed in 22 pts. Grade 3 toxicities included diarrhea (n=5), fatigue (n=4), nausea (n=6), neutropenia (n=10), thrombocytopenia (n=4), and vomiting (n=4). 34/36 pts developed some acneiforme rush during therapy. No omittance of cetuximab was necessary in any of the pts. 1 patient died during treatment due to tumor bleeding. Median follow-up at present is 13 month, 1-year survival was 57%, median survival has not been reached. Partial remissions 12/36, stable disease 20/36, progressive disease 4/36 (RECIST). 21/36 pts were amenable for secondary potentially curative resection. 9 pts could be resected, while 8 pts were found to have abdominal metastatic spread. Conclusions: Early data from trimodal therapy in pancreatic adenocarcinoma with chemoradiation (IMRT), gemcitabine, and cetuximab indicate feasibility without increased toxicity profile. The local response appears to be very promising in pancreatic cancer. [Table: see text]

Abstract
Transplantation-associated microangiopathy (TAM) or renal insufficiency (RI) after allogeneic hematopoietic stem cell transplantation is associated with a high mortality. As calcineurin inhibitors (CI) may contribute to TAM or RI, we evaluated the efficacy of replacing CI by daclizumab in patients with graft-versus-host disease (GVHD). Thirteen patients with GVHD-associated TAM and five patients with RI were treated with daclizumab 1 mg/kg intravenous (i.v.)/week, discontinuation of the CI and continuation of the remaining GVHD treatment. All patients had acute GVHD (steroid-sensitive (n=4), steroid-refractory (n=10)) or chronic GVHD (n=4) and were treated with CI before the start of daclizumab. Nine of 13 patients with TAM treated with daclizumab and discontinuation of CI achieved complete remission of TAM, two had stable disease, and one patient did not respond. Patients receiving daclizumab for RI without TAM showed stabilization (2/5) or improvement (3/5) of renal function. Four of 14 patients with acute GVHD achieved CR, two partial remission, eight patients did not respond and 11/14 died at a median of 39 days after start of the daclizumab. Our data demonstrate that replacement of CI by daclizumab can improve TAM and RI. However, mortality remains high in patients with acute GVHD.

Abstract
PURPOSE After neoadjuvant radiochemotherapy and surgery, there is no general agreement about whether postoperative chemotherapy is necessary. With the help of clinical and pathohistologic data, prognostic factors were determined as a basis for the decision to spare a patient additional chemotherapy or to urgently recommend it. RESULTS Ninety-five patients treated with neoadjuvant 5-fluorouracil-based radiochemotherapy (November 4, 1997 and June 15, 2004) without distant metastases and an R0 (microscopically complete) resection were evaluated. Adjuvant chemotherapy (5-fluorouracil or 5-fluorouracil/folinic acid) was given to 65 of 95 patients (68.4 percent). The disease-free survival rate after 36 months was chosen as the target parameter (median follow-up, 36 months). METHODS The five-year survival rate for all patients was 80.3 +/- 5.6 percent; the five-year disease-free survival was 78.1 +/- 5.1 percent; the five-year local control rate was 94.2 +/- 5.1 percent. In the univariate and multivariate analysis of the disease-free survival, the pathohistologic lymph node status after radiochemotherapy (ypN) was the only significant prognostic parameter. Disease-free survival (36 months) for patients without lymph node metastases (ypN0) was excellent, independent of whether they had received postoperative chemotherapy (n = 43; 87.5 +/- 6.0 percent) or not (n = 29; 87.7 +/- 6.7 percent). Patients with ypN2 status have, despite chemotherapy, a poor disease-free survival at 30 +/- 17.6 percent after 36 months. CONCLUSIONS These retrospective data suggest that, for some patients, postoperative chemotherapy can be spared. For patients with ypN2 status, an intensification of the postoperative chemotherapy should be considered. Further evaluation in prospective studies is urgently recommended.

Abstract
BACKGROUND During the last several years, major progress has been made in developing targeted chemotherapy using cytotoxic drugs covalently bound to human serum albumin (HSA). We explored the activity of two antifolates methotrexate (MTX) and aminopterin (AMPT) bound to HSA in prophylaxis and treatment of experimental acute graft-versus-host disease (aGVHD). METHODS In all, 113 female F1 hybrid BN/Lew-rats were irradiated with 8.2 Gy (n=103) or 9.9 Gy (n=10). One day after irradiation each rat received 4 x 10 bone marrow cells and 1.5 x 10 spleen T-cells from female Lew-rats. GVHD prophylaxis consisted of MTX-HSA 2 mg/kg (n=25), MTX-HSA 0.5 mg/kg (n=8), AMPT-HSA 0.65 mg/kg (n=8), MTX 0.5 mg/kg (n=17), or native HSA (n=39) given intraperitoneally (IP) on days 0, 4, 8, and 12. Treatment of aGVHD consisted of MTX-HSA 2 mg/kg (n=8) or AMPT-HSA 0.5 mg/kg (n=8) given intraperitoneally at the time of onset of aGVHD and subsequently every fourth day (a total of four doses). RESULTS All animals receiving native HSA developed lethal aGVHD. Prophylactic treatment with MTX-HSA 2 mg/kg prevented aGVHD in 18 of 25 animals and in 6 of 8 receiving AMPT-HSA. In contrast, five out of nine rats receiving free MTX died due to aGVHD. The survival rates in the prophylactic MTX-HSA 2 mg/kg and AMPT-HSA groups were significantly higher compared to the MTX and control groups (P<0.05), while non hematologic toxicity of MTX-HSA was not detectable. AMPT-HSA at a dose of 0.65 mg/kg as well as MTX at a dose of 0.5 mg/kg were associated with temporary weight loss and lethargy. CONCLUSIONS The albumin conjugates MTX-HSA and AMPT-HSA effectively prevent experimental aGVHD.

Abstract
4100 Background: The induction of EGFR targeting with cetuximab in radiation based therapy of solid tumors has yielded promising results. Thus, we initiated a prospective Phase II trial designed to analyze the feasibility and effectivity of trimodal therapy with gemcitabine-based chemoradiation and cetuximab in locally advanced inoperable pancreatic cancer. Methods: In this phase 2 study, pts with locally advanced pancreatic cancer without prior cytotoxic therapy were treated with radiotherapy (RT), gemcitabine weekly (300 mg/m2), and cetuximab weekly (loading dose 400 mg/m2 day 1, and concomitant with radiation day 8,15,22,29,36 250 mg/m2). RT was delivered by using an integrated IMRT boost concept (54 Gy GTV, 45 Gy CTV) over 5 weeks. RT was followed by gemcitabine (1000 mg/m2) weekly × 3 in 4 weeks. Response evaluation using computed tomography followed at week 12. All amenable patients were intended for surgical treatment between week 12–15. Results: 24 pts were enrolled until now. Preliminary results are presented on 20 pts with the following characteristics: pancreatic adenocarcinoma c2 T4 N1 20/20, median age = 63.5 (range 51–79); M/F = 13/7; ECOG PS 0/1/2 = 2/12/6; median days on treatment: 90 (range 70–100). Treatment-related toxicities were observed in 16 pts. Grade 3 toxicities included diarrhea (n = 4), fatigue (n = 2), nausea (n = 3), neutropenia (n = 6), thrombocytopenia (n = 2), and vomiting (n = 2). 18/20 pts developed some acneiforme rush during therapy. No omittance of cetuximab therapy was necessary. 1 patient died during RT due to tumor bleeding. Median follow-up at present is 6 month, median survival has not been reached. Partial remissions 8/20, stable disease 9/20, progressive disease 3/20. 12/20 patients were amenable for secondary potentially curative resection. 4 patients could be resected, while 3 patients were found to have abdominal metastatic spread. Conclusions: Early data from trimodal therapy in pancreatic adenocarcinoma with chemoradiation (IMRT), gemcitabine, and cetuximab indicate feasibility without increased toxicity profile. The local response appears to be very promising in pancreatic cancer, potentially allowing neoadjuvant treatment. [Table: see text]

Abstract
INTRODUCTION The transfer of allogeneic lymphocytes contained in a hematopoietic stem cell graft confers an immune-mediated antileukemic effect, termed the graft-vs-leukemia (GVL) effect. Graft-vs-host disease (GVHD), the most detrimental complication of allogeneic BMT, largely resides within the same lymphocyte population. Therefore, separation of GVL- and GVH-reactions is a long-standing goal of experimental studies dealing with allogeneic transplantation of hematopoietic stem cells. MATERIALS AND METHODS The objective of the current study was to assess the potential of Th1- and Th2-type CD4+ T cells in mediating GVHD and GVL effects in a fully allogeneic murine transplant model. BALB/c (H-2d) mice were given a dose of A20 (H-2d, B-cell leukemia) cells two days prior to lethal total body irradiation (TBI) and transplantation of fully mismatched (C57BL/6, H-2b) T-cell depleted (anti-Thy1.2, CD90) bone marrow (TCD-BM) cells. Graded numbers of either unmanipulated, Th1- or Th2-polarized highly enriched CD4+ donor type T cells (10(6) or 10(7)) were administered 2 h posttransplant. Infusion of 10(6) of unmanipulated, Th1-, or Th2-primed CD4+ T cells resulted in moderate GVHD-related mortality (40%, 50%, 10%) and significantly improved long-term survival (50%, 45%, 46% surviving the observation period of 120 days) as compared to animals receiving TCD-BM alone (18%). RESULTS The administration of 10(7) unmanipulated or Th1-type CD4+ T cells given shortly after transplantation led to death of all mice within 50 days due to fatal acute GVHD. In contrast, the adoptive transfer of 10(7) Th2-primed CD4+ T cells resulted in significant improvement of long-term survival (80%) compared to the TCD-BM group. This powerful GVL effect was associated with a substantially lower incidence of lethal acute GVHD (10%) if compared to the results of transplantation of Th1-type CD4+ T cells. CONCLUSION These results demonstrate that allogeneic Th2-type CD4+ T cells given post BMT can induce GVL effects in a cell-dose-dependent manner without increasing the risk of severe acute GVHD.

Abstract
BACKGROUND AND OBJECTIVE Allogeneic transplantation can not be offered to many patients due to potential side-effects of conventional conditioning. Dose-reduced conditioning approaches improve tolerability, however, treatment efficacy may be reduced as well. We have, therefore, developed a dose intense but toxicity reduced conditioning regimen based on treosulfan and fludarabine and report first results. PATIENTS AND METHODS 65 patients with a median age of 50 years were transplanted from related (n = 21) or unrelated donors (n = 44) after conditioning with treosulfan (3 x 10, 3 x 12 or 3 x 14 g/m(2) i. v.) and fludarabine (5 x 30 mg/m(2) i. v.). 21 patients were in complete remission (CR) and 44 patients had not reached a CR at the time of transplantation. 59 of 65 patients were considered unfit for a conventional conditioning regimen. RESULTS The actuarial overall survival after 3 years is 59.2 %, the event-free survival 40.1 %. Patients with a related donor or transplantation in CR had a better overall (85.4 resp. 74.2 %) and event-free survival (52.2 % resp. 61.9 %). The cumulative incidence of relapse at 3 years was 26.2 %. Non-relapse mortality at day 100 is 17.4 % (cumulative incidence). In stepwise Cox regression analyses for overall survival, event-free survival and non-relapse mortality the covariables transplantation in CR vs. not in CR and the donor status were shown to be influential. CONCLUSIONS These results with a conditioning therapy of treosulfan and fludarabine indicate that patients despite higher age, concomitant disease or after intensive pretreatment can be successfully transplanted without increased treatment-related mortality.

Abstract
BBR 3438, a member of the 9-aza-anthrapyrazole family designed to decrease anthracycline dependent cardiotoxicity and to improve efficacy provided high in vivo activity in gastric carcinoma xenograft models. The present study was carried out to assess the efficacy and safety of BBR 3438 applied at a dose of 50 mg/m(2) four-weekly as an 1-hour infusion to pretreated patients with gastric cancer. Twenty-seven patients received at least one administration of BBR 3438. Lymph nodes and liver were the most common sites of metastases. A total of 94 cycles were administered (median 2, range 1-6). The main toxicity consisted of (worst per patient [%]; NCIC CTC grades 1/2/3/4) neutropenia 7/7/19/52 (one case of febrile neutropenia), stomatitis 15/19/4/-, nausea 22/26/7/-, vomiting 19/7/7/-, alopecia 15/33/-/-. Neutrophil nadir (520/mul) was reached after a median 15 days. The median time to recovery to < or = grade 1 neutropenia was 13.5 days. The median average cumulative dose of BBR 3438 was 166.8 mg, and the median dose intensity was 48.8 mg/m(2). Left ventricular ejection function (LVEF) was monitored with multiple-gated angiography (MUGA). Median LVEF values at baseline and at the end of cycle 2 were 67.5% and 65%, respectively, and no patient showed a relevant decrease of LVEF. In 25 patients evaluable for response no remission was observed. Four patients (16%) had stable disease. Median time to progression was 51 days, median overall survival was 64 days. In all, the feasibility and tolerability of BBR 3438 applied 4-weekly at a dose of 50 mg/m(2) was confirmed and neither relevant LVEF decreases nor hints of cardiac toxicity were observed. In terms of antitumor activity, BBR 3438 was found to be ineffective in the treatment of gastric cancer.

Abstract
BACKGROUND In a phase III study recruiting patients with stage II colon cancer the effect of adjuvant therapy with edrecolomab, a murine monoclonal antibody to the cell-surface glycoprotein 17-1A, was compared to observation alone. PATIENTS AND METHODS From January 1997 until July 2000 a total of 377 patients were postoperatively stratified according to tumor stage (T3 vs. T4) and center, and randomly allocated to either treatment with edrecolomab (cohort A, n = 183) or observation (cohort B, n = 194). Patients in cohort A received a total of 900 mg edrecolomab. The study was terminated prematurely because of discontinuation of drug supply in Germany. RESULTS 305 patients were eligible for the primary endpoint of overall survival and 282 patients for disease-free survival. After a median follow-up of 42 months overall survival and disease-free survival were not significantly different. Toxicity was mild. CONCLUSIONS In the present study, postoperative adjuvant treatment with edrecolomab in patients with resected stage II colon cancer did not improve overall or disease-free survival.

Abstract
Steroid-resistant acute GVHD (aGVHD) following allogeneic hematopoietic stem cell transplantation (alloHSCT) continues to be associated with a high mortality. We report the results of a phase II study of treatment of steroid-resistant aGVHD with the IL-2 receptor antibody daclizumab combined with the TNF-receptor fusion protein etanercept. Treatment consisted of daclizumab 1 mg/kg given i.v. on days 1, 4, 8, 15, 22 and etanercept 16 mg/m(2) s.c. on days 1, 5, 9, 13, 17. A total of 21 patients (age 15-61 years) with steroid-resistant aGVHD after alloHSCT were included in the study. Donor types were HLA-matched related (n=6), HLA-matched unrelated (n=14), and HLA-mismatched unrelated (n=1). Eight patients achieved complete, and six showed partial remission of aGVHD. Seven patients did not respond. Four of 21 patients are currently alive with a median follow-up of 586 (185-1155) days. Three patients died due to relapsed malignancy. Treatment-related mortality was due to infectious complications (n=11) or organ failure due to aGVHD (n=3). In total, 12 patients developed subsequent chronic GVHD. In conclusion, the data demonstrate an acceptable response rate of the combination of daclizumab and etanercept in the treatment of steroid-resistant aGVHD. Nevertheless, long-term mortality due to infectious complications and chronic GVHD remains high.

Abstract
The aim of this study was to determine the dose-limiting toxicity (DLT) and establish the recommended dose for mitomycin C added every 3 weeks to the standard combination dose of capecitabine. Cohorts of at least three patients with pretreated gastrointestinal carcinoma received capecitabine 1000 mg m(-2) orally twice daily on days 1-14 plus i.v. bolus mitomycin C on day 1 at doses of 4, 6, 8 or 10 mg m(-2) (corresponding to dose levels I-IV). Cycles were repeated every 3 weeks. Two treatment cycles were considered for the evaluation of DLTs. Of the 53 patients enrolled, the majority had colorectal (n=27) or gastric (n=14) cancers. Patients had received a median of two lines of prior chemotherapy (34% with >/=3 lines and 87% with prior 5-FU-based therapy). At the recommended dose level (IV, n=30), grade 3 adverse events during cycles 1 and 2 were: anaemia (10%); leukopenia (3%); thrombocytopenia (3%); stomatitis/mucositis (3%); hand-foot syndrome (3%). Two patients experienced DLTs (mucositis, n=1; neutropenic fever, n=1), but there were no grade 4 events. The median dose intensity for capecitabine and mitomycin C was 100% during cycles 1 and 2 and only four patients required postponement of therapy. Of the 43 patients evaluable for efficacy, seven achieved partial and minor remissions (16%; 95% CI, 5-28%), and 12 patients (28%) had stable disease. The favourable safety profile and promising activity of the capecitabine/mitomycin C combination, even in heavily pretreated patients, warrant further evaluation in patients with advanced colorectal and gastric cancers.

Abstract
New conditioning regimens are being explored to reduce toxicity and enable allogeneic bone marrow transplantation in patients not eligible for conventional transplantation. We have investigated treosulfan, an alkylating agent, with the aim of developing an efficient and reliable but less-toxic conditioning regimen. A series of 30 patients who were not eligible for standard conditioning therapy received transplants from HLA-matched related (n = 14) or unrelated (n = 16) donors after administration of treosulfan 10 g/m2 intravenously daily for 3 days and fludarabine 30 mg/m2 intravenously daily for 5 days. Patients receiving grafts from unrelated donors also were given rabbit antithymocyte globulin 10 mg/kg intravenously daily for 3 days. All patients achieved prompt neutrophil and platelet recovery. Extramedullary toxicity was generally mild with Common Toxicity Criteria (CTC) grade 3 or 4 attributable to the conditioning seen only with transaminases. Complete donor chimerism was achieved by 90% of the patients. Acute graft-versus-host disease (GVHD) grade III or IV developed in 14% of the patients and chronic GVHD in 39%. An estimated overall survival rate of 73% and an event-free survival rate of 49% have been reached after a median of 22 months (range, 7.4-33.4 months). In summary, the combination of treosulfan and fludarabine is a safe and efficient conditioning regimen.

Abstract
The graft vs. leukemia (GVL) effect is one of the most important factors of anti-tumor activity after allogeneic hematopoetic stem cell transplants (alloSCT). Its effectiveness depends mainly on the tumor biology as well as the tumor burden. Patients with a high tumor burden may not respond to GVL-effect despite otherwise sensitive biology. Campath-1H is known as an effective treatment of chronic lymphocytic leukemia (CLL). Due to its ability to induce profound immunosuppression, it has also been used as part of conditioning regimens before alloSCT. We report a patient, who received campath-1H in combination with docetaxel for treatment of chemotherapy and donor lymphocyte infusion resistant CLL after alloSCT, who developed shortly after discontinuation of treatment with campath-1H severe eosinophilia of the peripheral blood and typical clinical as well as histological signs of cutaneous chronic graft vs. host disease followed by complete clearance of CLL. The clinical course demonstrates the impact of the tumor burden on the GVL-effect, as well as the effectiveness of campath-1H in the presence chemo-resistance in a patient with CLL. Furthermore, the GVL effect was not abrogated by the use of campath-1H.

Abstract
Allogeneic peripheral blood progenitor cells (PBPCs) have mostly been mobilized by granulocyte colony-stimulating factor (G-CSF). There is neither clinical nor experimental data available addressing the question if other hematopoietic growth factors or combinations thereof might influence engraftment, graft-versus-host disease (GvHD), and graft-versus-leukemia (GvL) effects after allogeneic peripheral blood progenitor cell transplantation (PBPCT). We used a murine model to investigate these parameters after transplantation of PBPCs mobilized with G-CSF and SCF either alone or in combination. Treatment of splenectomized DBA and Balb/c mice with 250 microg/kg/day G-CSF for 5 days resulted in an increase of CFU-gm from 0 to 53/microl. The highest progenitor cell numbers (147/microl) were observed after treatment with 100 microg/kg/day SCF administered in conjunction with G-SCF. No differences were detected with regard to the number of T cells (CD3+), T cell subsets (CD4+, CD8+), B cells (CD19+) and NK cells (NK1.1+) in PBPC grafts mobilized by G-CSF plus SCF compared to those mobilized with G-CSF alone. The antileukemic activity of syngeneic and MHC-identical allogeneic PBPC grafts was investigated in lethally irradiated Balb/c mice bearing the B-lymphatic leukemia cell line A20. In this model, PBPCs mobilized by G-CSF plus SCF exerted a significantly higher antileukemic activity compared to grafts mobilized by G-CSF alone (94 vs 71% freedom from leukemia at day 100, P<0.05). The antileukemic effect was lowest after BMT (38% freedom from leukemia). Since significant differences in the incidence of lethal GvHD were not observed, improved GVL-activity resulted in superior overall survival. Our data demonstrate that the utilization of specific hematopoietic growth factors not only improve the yield of hematopoietic progenitor cells but can also significantly enhance the immunotherapeutic potential of allografts.

Abstract
Pseudomembranous tracheobronchial aspergillosis coincident with systemic pulmonary aspergillosis represents a rare manifestation of fungal infection in immunocompromized hosts. We report on a patient with recurrent Hodgkin's disease, showing this infectious pattern after treatment with corticosteroids within the antineoplastic schedule, whereas neutropenia--the main risk factor for mold infections--had not occurred. An impaired number of helper T lymphocytes was merely detected as an additional, but hypothetical risk factor, when investigating the status of immunosuppression. Treated systemically with amphotericin B, the patient recovered quickly, although reported mortality rates are disastrous. What is crucial for the clinical management is an early diagnosis by bronchoscopy and cultural proof of the pathogen followed by an adequate antifungal treatment.

Abstract
BACKGROUND A novel immunological approach to colon cancer therapy is the antibody targeting of the fibroblast activation protein (FAP), which is highly expressed by stroma cells of this tumour. Unconjugated sibrotuzumab (BIBH 1), which is a humanised version of the murine anti-FAP mAb F19, was investigated for its anti-tumour activity, safety and pharmacokinetics. PATIENTS AND METHODS Patients with metastatic colorectal cancer received weekly intravenous infusions of unconjugated sibrotuzumab at a dose of 100 mg over 12 scheduled weeks. The study was implemented as an open-label, uncontrolled, multicentre trial. RESULTS 25 patients were enrolled. Patients had one or more measurable lesions, predominantly liver lesions, at baseline. At least 8 repeated weekly infusions of sibrotuzumab in 17 evaluable patients did not result in complete or partial remission. Rather, ongoing tumour progression was noted in all patients except for 2 patients with stable disease. However, progressive disease was also observed post-study in these 2 patients who received 1 and 6 additional infusions, respectively, of sibrotuzumab. Sibrotuzumab exhibited 2-compartment pharmacokinetics with a dominant terminal phase and t1/2 beta = 5.3 +/- 2.3 days. Adverse drug reactions (rigors/chills, nausea, flushing and one incidence of bronchospasm) were observed in 5 patients. Of the 24 patients given 2 or more infusions of sibrotuzumab, antibodies against sibrotuzumab were found in 3 patients (12.5%) after 4-12 infusions. CONCLUSIONS Sibrotuzumab was well tolerated and safe. The minimal requirement for the continuation of this exploratory trial, of at least one complete or partial remission, or equivalently, of 4 patients with stable disease, was not met.

Abstract
Peripheral T-cell lymphomas (PTCL) are a rare entity of non-Hodgkin's lymphomas (NHL). Despite the poor outcome after conventional chemotherapy, the impact of high-dose chemotherapy (HDCT) and autologous or allogeneic stem cell transplantation is not well defined in these patients. In a retrospective study, we evaluated the outcome of 15 patients (9 male, 6 female) with PTCL after HDCT with autologous (10 patients) and allogeneic (5 patients) stem cell transplantation between 1996 and 2001 at our department. At the time of transplantation three patients were in second remission, seven patients were in partial remission (PR), and three patients had refractory disease. Two patients were treated with sequential HDCT (cyclophosphamide, adriamycin, vincristine, etoposide, prednisolone, m-CHOEP). The conditioning regimes were heterogeneous. After HDCT ten patients (67%, autologous 7, allogeneic 3) achieved CR, two patients (13%, autologous 2, allogeneic 0) had refractory disease, and three patients (20%, autologous 1, allogeneic 2) died because of toxic side effects before evaluation of response was performed. The median overall survival (OS) was 12 months. The 1-year probability of survival for the autologous and allogeneic groups was 58% and 40%, respectively. At the time of evaluation, six patients are alive and nine patients have died (four severe infection, one late toxicity, two disease progression, and two relapse). Despite the small number of patients in this study, HDCT with autologous or allogeneic hematopoietic transplantation seems to be an effective treatment option that can achieve CR for patients with PTCL. Because of the poor outcome of these patients after conventional chemotherapy, HDCT seems to be a rational option in first-line therapy. Whether it improves survival in these patients should be further investigated.

Abstract
UNLABELLED Irinotecan (CPT-11) has been shown to prolong survival and improve quality of life in comparison to best supportive care in colorectal cancer patients with pretreatment of bolus 5-fluorouracil (5-FU). After first-line 24-h high-dose (HD) 5-FU/folinic acid (FA) an objective response rate of 11% with 3-weekly CPT-11 350 mg/m was reported. In the present study we investigated weekly CPT-11 in combination with 24-h HD-5-FU/FA as second-line treatment after prior exposure to 24-h HD-5-FU. Synergy between 5-FU and CPT-11 is the rationale to combine both substances for second-line therapy in order to overcome resistance to 5-FU. Thirty-five patients were recruited in a single institution to receive 6 x weekly CPT-11 80 mg/m(2), FA 200 mg/m(2) and 24-h HD-5-FU 2000 mg/m(2). Treatment was repeated on day 57. PATIENT CHARACTERISTICS M/F=20/15, median WHO performance status 1, range (0-2). Thirty-four patients were evaluable for response: partial response 17% and no change 40%. Median time to progression and overall survival were 3.3 and 8.4 months, respectively. All patients were evaluable for toxicity analysis (National Cancer Institute Common Toxicity Criteria grade 3): leukocytopenia 3%, diarrhea 12% and vomiting/nausea 6%. Of the assigned doses, a median 100% of 5-FU and 92% of CPT-11 were administered during the first cycle of chemotherapy. We conclude that weekly CPT-11 and HD-5-FU/FA is an active and safe combination chemotherapy resulting in response rates in the upper range of other CPT-11-based second-line regimen. The toxicity profile in our series compared to 3-weekly CPT-11 seems favorable.

Abstract
BACKGROUND Adjuvant chemotherapy for colon cancer has been established during the past decade. From 1990 until recently treatment with 5- fluorouracil (5-FU) and levamisole (LEV) lasting 12 months was recommended as standard treatment. At the initiation of this study in 1993 improvement of adjuvant therapy was expected by the modulation of 5-FU with folinic acid (FA). Therefore, we decided to perform a prospective randomized multicenter trial to compare standard 5-FU/LEV to 5-FU/FA for either 6 or 12 months. PATIENTS AND METHODS Patients with stage III colon cancer after curative en bloc resection were randomized in 3 treatment groups: arm A (5-FU/LEV, weekly, 12 months), arm B (5-FU/FA, days 1-5, every 4 weeks, 12 months) and arm C (like B, 6 months). RESULTS Between March 1993 and November 1997, 180 patients were randomized into the study, 155 were eligible for further evaluation. The interim analysis in November 2000 showed no significant difference for recurrence and disease-free survival in arm B and C, therefore the data from both 5-FU/FA treatment arms (B+C) were combined for comparison with 5-FU/LEV-treatment (A). Most pronounced toxicity in all treatment arms was mild nausea, loss of appetite and leukopenia. A tendency for more diarrhea and stomatitis was observed in arm B+C. After a median follow-up of 36.2 months no significant difference was seen for disease free survival (p = 0.9) and overall survival (p = 1.0). 3-year recurrence rates were 39.6% in arm A and 39.1% in arm B+C, 3-year survival rates amounted to 74.1% in arm A and 74.9% in arm B+C. CONCLUSION Only a limited number of patients could be recruited in this study. The observed data support the results of other studies, which concluded that 6 months (or 12 months) treatment with 5-FU/FA is equivalent to 12 months treatment with 5-FU/LEV. Therefore the 6 months treatment with 5-FU/FA can be supported as standard for adjuvant therapy of stage III colon cancer.

Abstract
Gene therapeutic approaches currently favor adenoviral vectors over alternatively available vector systems. Ovarian cancer represents an attractive model for an intraperitoneal adenovirus-based gene therapy, which is now under intensive clinical investigation. Adenovirus-mediated gene transfer depends on adequate virus uptake and thus on the presence of sufficient amounts of high-affinity coxsackie-adenovirus receptor (CAR) and alphavbeta3- and alphavbeta5 integrins on target cells. This fact has been ignored in most ongoing clinical trials. This investigation, therefore, determined expression of CAR by immunohistochemistry in 37 ovarian carcinomas and compared it with that of alphavbeta3 and alphavbeta5 integrins. In all samples, except one undifferentiated carcinoma, CAR was immunohistochemically demonstrable. Grade 1 tumors exhibited stronger CAR immunostaining as compared with higher-grade cancers (P < 0.03). Integrins alphavbeta3 and alphavbeta5 were detectable in 62% and 65% of carcinomas, respectively, and staining for both classes correlated positively (P < 0.005). Cancers classified as undifferentiated completely lacked alphavbeta3 expression. Furthermore, in undifferentiated and grade 3 carcinomas the three molecules studied exhibited marked distributional heterogeneity with regard to focal positivity and negativity within the same tumor. Either the absence of CAR, alphavbeta3 and alphavbeta5 or the pronounced heterogeneity in their expression might seriously compromise the efficiency of adenovirus-based gene therapy in ovarian cancer.

Abstract
The antifolate aminopterin (AMPT) was developed before methotrexate (MTX), but was not clinically established or generally used due its increased toxicity compared to MTX. Recently, we reported on the increased metabolism of albumin conjugates such as methotrexate-albumin (MTX-SA) in malignant tumors and the feasibility of using albumin as a carrier for drug targeting. Consequently, AMPT was covalently bound to serum albumin (AMPT-SA) at a 1:1 molar ratio. Biodistribution, tolerability and efficacy of this novel conjugate were studied in Walker-256 (W-256) carcinoma-bearing rats. As compared to native albumin, the same biodistribution and plasma clearance were found for AMPT-SA, which achieved 20.1% tumor uptake (estimated uptake per g tumor 6.4%) within 24 h after i.v. administration in rats. In a randomized study, AMPT-SA, repeatedly i.v. injected, was compared with low-molecular-weight AMPT. Depending on the molar concentration, the maximum tolerated dose (MTD) of AMPT covalently bound to SA was twice that of unbound AMPT (three repeated injections of 1.0 mg AMPT-SA/kg body weight versus three repeated injections of 0.5 mg AMPT/kg body weight; p=0.0006). Efficacy was studied at the level of the MTD and MTD/2, and demonstrated that AMPT-SA was significantly more active. At the MTD/2 in W-256 carcinoma-bearing rats, AMPT-SA achieved a 100% volume reduction and an optimal volume reduction during treatment/control (T/C) of 8.3% compared to a 53% volume reduction of AMPT and a T/C of 16.5% (p=0.032). Tumor relapses were reduced and occurred later in the AMPT-SA group (two tumor recurrences for AMPT-SA versus seven for AMPT; p=0.05). In this comparative study, the AMPT-SA conjugate showed high antitumor activity in vivo and a favorable toxicity compared to low-molecular-weight AMPT. These effects are attributed to the albumin carrier which seems to be an effective tool for selective tumor drug targeting.

Abstract
BACKGROUND The 24-hour continuous infusion of 5-fluorouracil (5-FU) and folinic acid (FA) as part of several new multidrug chemotherapy regimens in advanced gastric cancer (AGC) has shown to be effective, with low toxicity. In a previous phase II study with 3-weekly bolus 5-FU, FA and mitomycin C (MMC) we found a low toxicity rate and response rates comparable to those of regimens such as ELF, FAM or FAMTX, and a promising median overall survival. In order to improve this MMC-dependent schedule we initiated a phase II study with high-dose 5-FU/FA and 3-weekly bolus MMC. PATIENTS AND METHODS From February, 1998 to September, 2000 we recruited 33 patients with AGC to receive weekly 24-hour 5-FU 2,600 mg/m(2) preceded by 2-hour FA 500 mg/m(2) for 6 weeks, followed by a 2-week rest period. Bolus MMC 10 mg/m(2) was added in 3-weekly intervals. Treatment given on an outpatient basis, using portable pump systems, was repeated on day 57. Patients' characteristics were: male/female ratio 20/13; median age 57 (27-75) years; median WHO status 1 (0-2). 18 patients had a primary AGC, and 15 showed a relapsed AGC. Median follow-up was 11.8 months (range of those surviving: 2.7-11.8 months). RESULTS 32 patients were evaluable for response - complete remission 9.1% (n = 3), partial remission 45.5% (n = 15), no change 27.3% (n = 9), progressive disease 15.1% (n = 5). Median overall survival time was 10.2 months [95% confidence interval (CI): 8.7-11.6], and median progression-free survival time was 7.6 months (95% CI: 4.4-10.9). The worst toxicities (%) observed were (CTC-NCI 1/2/3): leukopenia 45.5/18.2/6.1, thrombocytopenia 33.3/9.1/6.1, vomitus 24.2/9.1/0, diarrhea 36.4/6.1/3.0, stomatitis 18.2/9.1/0, hand-foot syndrome 12.1/0/0. Two patients developed hemolytic-uremic syndrome (HUS). CONCLUSIONS High-dose 5-FU/FA/MMC is an effective and well-tolerated outpatient regimen for AGC (objective response rate 54.6%). It may serve as an alternative to cisplatin-containing regimens; however, it has to be considered that possibly HUS may occur.

Abstract
The accuracy of stereoscopic and standard three-dimensional (3D) CT in the classification of acetabular fractures was compared. A receiver operating characteristic (ROC) analysis was performed by two radiologists and two surgeons blinded to the presence of acetabular fractures in an animal model (a total of 62 porcine hips, 40 with artificial acetabular fractures). Classification of acetabular fractures was adopted from the literature. Interpretation was performed on a workstation using two specific volume rendering algorithms; unshaded and shaded bone. The ROC analysis did not demonstrate any benefit in stereoscopic 3D CT compared with standard 3D CT.

Abstract
BACKGROUND A weekly continuous 24-hour infusion therapy with 5-fluorouracil (5-FU) and calcium - folinic acid (CA-FA) was shown to be an effective first-line treatment in advanced metastatic colorectal cancer. Sodium - folinic acid (S-FA) is a new formulation which, in contrast to CA-FA allows the simultaneous i.v. administration in combination with 5-FU in one pump. PATIENTS AND METHODS From 1997 to 1998, 51 patients [median age 60 (range 24-77) years; 38 male, 13 female] with metastatic colorectal cancer were recruited in 5 centers to receive weekly 24-hour infusions of 5-FU (2,600 mg/m(2)) and S-FA (500 mg/m(2)) dissolved in one pump for 6 weeks as first-line treatment. The treatment cycle was repeated after a 2-week rest period. RESULTS 1,178 administrations (median 24, range 3-54) were performed during the study. Out of 51 patients (median follow-up 20.2 months), 2 (3.9%) achieved complete remission (CR), 17 (33.3%) partial remission (PR), and 21 (41.2%) no change (NC). Progressive disease (PD) was observed in 11/51 (21.6%) patients, including 6 patients who did not complete the first cycle. Median time to tumor progression (TTP) was 8.5 months (95% CI: 5.8-11.3). 32/51 (62.7%) patients survived for more than 1 year, the median survival was reached at 16.5 months (95%CI: 10.2-22.8). Among major toxicities, NCICTC grade III/IV diarrhea occurred in 13/51 (25.4%), grade III hand-foot syndrome in 6/51 (11.7%) patients. Grade III/IV stomatitis was observed in 4/51 (7.8%), cardiac toxicity occurred in 2/51 patients (3.9%). CONCLUSION Similar to conventional 24-hour 5-FU + CA-FA treatment, the combination with S-FA induced 37.2% objective responses with moderate toxicity. However, TTP seems favorable and the administration of S-FA is convenient, while saving costs and time for the patient in outpatient units.

Abstract
BACKGROUND Postoperative radio-chemotherapy has been established as standard treatment for stage II and III rectal cancer patients in the last decade. To improve the efficacy of this therapy, we decided to evaluate continuous 24-hour infusion of 5-fluorouracil (5-FU) with folinic acid (FA) in combination with local radiation versus standard bolus 5-FU/FA with local radiation in a randomized study. Here we report on the first 28 patients to receive the experimental treatment. PATIENTS AND METHODS Patients with stage II and III rectal cancer received weekly 2-hour infusions of FA 500 mg/m2 followed by continuous 24-hour infusions of 5-FU 2,600 mg/m2 postoperatively via a Port-A-Cath system. The first cycle included 8 consecutive weekly administrations, the 1st-4th in full dose, the 5th-8th with 50% reduced dose while local irradiation (45 or 50.4 Gy) was performed. Thereafter, two further chemotherapy cycles (6 weekly administrations, 100% dose) followed. RESULTS 28 patients received continuous 5-FU/FA treatment, of whom only 21 were evaluable for tolerability. 19 patients (90.4%) completed the first cycle, only 14 patients entered the second treatment cycle. Especially during the combined radiochemotherapy, increased toxicity was observed with grade III/IV diarrhea (n = 2), nausea (n = 1), leukopenia (n = 1), and cardiac toxicity (n = 1). CONCLUSION The high rate of premature treatment dropout indicate that the chosen schedule of weekly high-dose 5-FU/FA continuous infusion and combined postoperative radiotherapy should not be recommended for further use in postoperative adjuvant treatment.

Abstract
Limitations of low mol. wt anticancer drugs are short tumor exposure times and toxicity to normal tissue. Methotrexate (MTX) covalently linked to human serum albumin (HSA) as a macromolecular carrier caused tumor regressions concomitant with a favorable toxicity profile in a clinical phase I trial (Hartung et aL, Clin. Cancer Res., 1999, 5, 753). We examined the uptake, intracellular degradation, metabolism and thymidylate synthase (TS) inhibition of MTX-HSA in the T-cell leukemia line CCRF-CEM and the MTX transport resistant clone CCRF-CEM/MTX. The number of MTX molecules per albumin molecule was determined by electrospray mass spectrometry. A loading ratio (LR) of approximately 1.4 mol MTX/albumin revealed intact complexes with one and two MTX molecules/albumin. In the complex with an LR of 5.7, albumin with up to 16 MTX molecules was seen. MTX-HSA was taken up by CCRF-CEM cells via endocytosis and cleaved by lysosomal enzymes. Liberated MTX was a poor substrate of folylpolyglutamate synthetase and was exported into the medium. TS was inhibited and cell survival was impaired by MTX-HSA in a time- and concentration-dependent manner. CCRF-CEM/MTX cells exhibited a growth inhibition of 30-40% after MTX-HSA treatment, but no TS inhibition. The alternative uptake route via endocytosis enables MTX-HSA to overcome transport resistance to MTX.

Abstract
Methotrexate covalently bound to human serum albumin in a 1:1 molar ratio (MTX-HSA) is a new macromolecular drug which is currently being studied in phase I clinical trials by the German Association for Medical Oncology (AIO) Phase I/II study group. Previous studies have shown that MTX-HSA differs favorably from unbound MTX in terms of plasma half-life time, tumor accumulation of albumin and uptake mechanisms into cancer cells. To achieve optimal drug efficacy, repeated treatment cycles were necessary. To evaluate the anti-tumor activity of MTX-HSA and MTX in pre-clinical in vivo models, we selected 7 solid human tumor xenografts growing s.c. in nude mice and administered drug either i.p. or i.v. weekly for 3 weeks. The maximal tolerated dose (MTD) of MTX-HSA in nude mice was 12.5 mg/kg given i.p. on days 1, 8 and 15, whereas the MTD for free MTX was 100 mg/kg given i.v. MTX-HSA was significantly more active (p > 0.01) than MTX in 3 models. In the soft tissue sarcoma SXF 1301, MTX-HSA effected complete remission/cure after a single injection, whereas free MTX resulted in short-lasting, partial tumor regression. In the prostate-cancer model PRXF PC3M, MTX-HSA produced growth inhibition of 92.8% of control or an optimal test/control (T/C) of 7.2% compared to a T/C of 20.8% for MTX (p = 0.05). In the osteosarcoma model SXF 1410, optimal T/C values were 10.2% and 14.5%, respectively (p = 0.025). In lung cancers LXFE 409 and LXFL 529, bladder cancer BXF 1258 and breast cancer MAXF 449, both compounds were inactive. The improved therapeutic effects seen in 3 xenograft models under MTX-HSA treatment are promising and might be due to specific accumulation of the compound in solid tumors owing to their enhanced permeability and retention effect. Thus, clinical development of MTX-HSA will continue and sarcomas as well as prostate cancers will be included as potential target tumors for upcoming clinical phase II trials.

Abstract
The active immunization of bone marrow (BM) donors with myeloma immunoglobulin (Ig) results in an idiotypic T cell response that can be transferred to the recipient. Using a murine model we evaluated the effectiveness, side-effects and underlying mechanisms of this approach. Balb/c (H-2d) mice were given a dose of HOPC-1F myeloma cells secreting the monoclonal IgG2a followed by lethal total body irradiation (7.5 Gy) 2 days later and a subsequent transplantation of 2 x 10(7) allogeneic MHC-matched DBA/2-derived marrow cells. Donors were pre-immunized with three i.p. injections of HOPC(IgG2a) or control Ig given with incomplete Freund's adjuvants (IFA) spaced 1 week apart. In some experiments, donor-spleen cells were additionally transferred 2 h post transplant. Injection of HOPC-myeloma led to death of all animals after a median survival time (MST) of 42 days. A lethal dose of TBI followed by transfer of unmanipulated marrow grafts plus splenocytes resulted in moderate antimyeloma effects with 8% of mice achieving long-term survival. Nearly the same results were obtained after transplantation of BM immunized with the control Ig. In contrast, transplantation of marrow grafts from HOPC(IgG2a) immunized donors exerted a significant GVM effect with 63% long-term survival for more than 180 days. The additional transfer of 2 x 10(7) immune splenocytes derived from the same donor resulted in even stronger anti-myeloma effects (FFR 87%). No increase in the incidence of severe acute GVHD was observed. In vitro data suggest that allogeneic CD8+ idiotype-specific T cells may be the major effector cells. Our results demonstrate that active immunization of the donor with the myeloma-specific Ig can induce powerful graft-versus-myeloma effects after allogeneic BMT.

Abstract
BACKGROUND: Gastric carcinoma still is a worldwide major cause of cancer death. Although various chemotherapy schedules yielded high response rates, median survival rarely exceeds 8-10 months. Many regimens are inevitably associated with significant toxicity which jeopardizes their value as palliative treatment, especially in patients with reduced performances status. Therefore, we initiated a phase II study for the treatment of advanced gastric carcinoma using a bolus regimen with mitomycin C (MMC), 5-fluorouracil (5-FU) and folinic acid (FA), allowing the enrollment of elderly patients or those with reduced performance status (WHO grade 2). PATIENTS AND METHODS: Between 1996 and 1998 we recruited a total of 58 patients with advanced gastric cancer to receive bolus MMC 3 mg/m(2), 5-FU 450 mg/m(2), and FA 100 mg/m(2) on days 1-3. Treatment was repeated on day 22. 53 patients met the inclusion criteria: male n = 36, female n =17; median age 65 (range 26-81); mean WHO status 1 (range 0-2). RESULTS: Out of 53 patients 50 were evaluable for response, all 58 patients who received therapy were evaluable for toxicity. Eleven patients (22%) achieved partial remission (95% CI: 11.5 -36.0%), 24 (48%) no change and 15 (30%) were progressive. Median overall survival was 11.5 months, the median time to progression 6.0 months. Out of 290 treatment cycles the worst toxicities observed (WHO 2/3/4) were as follows: anemia 13/3/1, leukopenia 19/1/1, thrombopenia 11/3/0, nausea/emesis 11/2/0, infections 2/1/0, diarrhea 14/2/0, and stomatitis 6/1/1. One patient developed hemolytic-uremic syndrome. CONCLUSIONS: The tumor control rate (PR + NC) of 70% was comparable to established chemotherapy regimens, while median overall survival was promising. Toxicity was mild, allowing the treatment especially for elderly patients and on outpatient basis. Copyright 2000 S. Karger GmbH, Freiburg

Abstract
BACKGROUND: Immunotherapy with monoclonal antibody 17-1A (mAb 17-1A) has been shown effective as an adjuvant treatment in UICC stage III colon carcinoma. Usually, severe side effects are infrequent with mAb 17-1A treatment. CASE REPORT: A 64-year-old man had a 18-month history of recurring arthralgia, sinusitis, and conjunctivits. After curative resection of UICC stage II colon cancer adjuvant treatment with mAb 17-1A was initiated. After the first administration (500 mg) the patient experienced an aggravation of the above-mentioned symptoms which led to the diagnosis of Wegener's granulomatosis with multiorgan involvement. Under immunosuppressive therapy with cyclophosphamide and prednisone, clinical stabilization could be achieved. CONCLUSION: The exacerbation of Wegener's granulomatosis occurred immediately after the first administration of mAb 17-1A. This suggests that mAb 17-1A should be applied cautiously in autoimmune disease. Copyright 2000 S. Karger GmbH, Freiburg
