    Abstract: Purpose To evaluate prognostic factors for relapse-free survival (RFS) and overall survival (OS) and to assess the impact of different postremission therapies in adult patients with core binding factor (CBF) acute myeloid leukemias (AML). Patients and Methods Individual patient data-based meta-analysis was performed on 392 adults (median age, 42 years; range, 16 to 60 years) with CBF AML (t(8;21), n = 191; inv(1 6), n = 201) treated between 1993 and 2002 in prospective German AML treatment trials. Results RFS was 60% and 58% and OS was 65% and 74% in the t(8;21) and inv(16) groups after 3 years, respectively. For postremission therapy, intention-to-treat analysis revealed no difference between intensive chemotherapy and autologous transplantation in the t(8;21) group and between chemotherapy, autologous, and allogeneic transplantation in the inv(16) group. In the t(8;21) group, significant prognostic variables for longer RFS and OS were lower WBC and higher platelet counts; loss of the Y chromosome in male patients was prognostic for shorter OS. In the inv(16) group, trisomy 22 was a significant prognostic variable for longer RFS. For patients who experienced relapse, second complete remission rate was significantly lower in patients with t(8;21), resulting in a significantly inferior survival duration after relapse compared with patients with inv(16). Conclusion We provide novel prognostic factors for CBF AML and show that patients with t(8;21) who experience relapse have an inferior survival duration.

    Notes: Abstract We report the case of an unresected, metastatic gastric cancer, which was treated with a very short course of the oral 5-fluorouracil (5-FU) prodrug S-1. The patient had to discontinue chemotherapy during the first treatment cycle due to severe toxicity, but achieved a pathologically confirmed, long-term complete response of her primary tumour, a diffuse-type poorly differentiated adenocarcinoma.

    Notes: Abstract Background:The cytotoxic agent bendamustine combines apurine-like benzimidazol and alkylating nitrogen mustard group. The clinicallytolerated dose for single bolus bendamustine is 215 mg/m2, forfractionated therapy on four consecutive days 85 mg/m2. The maximumtolerated dose of a day 1 and 8 (q4w) 30 min infusion schedule was recentlyfound to be 160 mg/m2, mouth dryness and fatigue weredose-limiting. Our current phase I trial was designed to define therecommended dose of a new weekly short infusion schedule. Patients and methods:Patients with refractory malignant tumoursqualified for the trial after written informed consent was obtained.Bendamustine was given as a 30-min i.v. infusion weekly for up to eightconsecutive weeks. Results:Twelve patients (8 male, 4 female, median age 57.5 years,range 42–64) were enrolled in this trial. At the starting dose of 80mg/m2, two patients had dose-limiting toxicity (fatigue grade 3,mouth dryness grade 3, fever grade 4 Common Toxicity Criteria). Nodose-limiting events were observed in six patients treated at 60mg/m2. An intermediate dose level of 70 mg/m2 wasstudied in three younger, less heavily pre-treated patients, was welltolerated and not associated with dose-limiting events. Haematologicaltoxicity was mild except for grade 3–4 lymphocytopenia, occurring in 11of 12 patients. Bendamustine was found to induce long-lastingpanlymphocytopenia with predominant B-cell cytotoxicity. Conclusions:The maximum tolerated dose of weekly bendamustinegiven as a 30-min i.v. infusion is 80 mg/m2, mouth dryness, fatigueand fever are dose-limiting. The recommended dose for phase II trials is 60mg/m2.
