    Notes: Abstract  Primary end point of this trial was to reduce neutropenic infections during the treatment of aggressive NHL with CEOP/IMVP-Dexa (cyclophosphamide, epirubicin, vincristine, prednisolone ifosfamide, methotrexate, VP-16, and dexamethasone). Further, we studied the influence of filgrastim on dose intensity of CEOP/IMVP-Dexa, on the rate of complete remissions, on the time to relapse, and on survival. Eighty-five patients with untreated large-cell NHL were randomized to one of two treatment arms; 74 patients were eligible. Thirty-eight patients in arm 1 were treated with CEOP/IMVP-Dexa chemotherapy and filgrastim, 36 in arm 2 with CEOP/IMVP-Dexa chemotherapy alone. In arm 1 filgrastim was self-injected by the patients at 5 μg/kg body wt. s.c. daily, except on the days when cytotoxic drugs were given. During treatment we did weekly complete blood counts. Median leukocyte counts were 10.91×109/l and 5.46×109/l in arm 1 and 2, respectively (p=10–6). Median neutrophil counts were 7.7×109/l in arm 1 and 2.72×109/l in arm 2 (p〈10–6). Median neutrophil nadirs were 0.199×109/l and 0.213×109/l in arm 1 and 2, respectively (p=0.09). Mean platelet nadirs were 95 and 152×109/l (p=0.000004) and mean hemoglobin nadirs 83.95 g/l and 92.78 g/l (p=0.00558) in arm 1 and 2, respectively. Dose intensity of CEOP/IMVP-Dexa was 82.3% and 76.2% in arm 1 and 2, respectively (p=0.041). Forty-two percent and 58% of patients experienced a febrile neutropenia in arm 1 and 2, respectively (not significant, NS). Median time to first neutropenic infection was in treatment week 11 and 6 in arm 1 and 2, respectively (NS). There was no significant difference in rate, duration, and kind of infection, duration of hospitalization, or antibiotic treatment. Seven toxic deaths occurred, all due to neutropenic infection, 6 and 1 in arm 1 and 2, respectively (p=0.0732). Four of the six patients, who died of infection in arm 1 were older than 60 years. Complete remission rate was 83% and 66.7% in arm 1 and 2, respectively (NS). After a median observation time of 3 years there was no difference in time to relapse or survival. Filgrastim increases leukocyte and neutrophil counts and dose intensity, if used with CEOP/IMVP-Dexa chemotherapy in high-grade lymphomas. There was no significant effect on febrile neutropenia or infections. The more frequent fatal neutropenic infection rate in the filgrastim arm was not statistically significant. It is most appropriate to explain it by the patient's age in combination with the high dose intensity. The small increase in dose intensity had no effect on survival but probably decreased hemoglobin levels and platelet counts in arm 1. We were unable to show a benefit for filgrastim in combination with CEOP/IMVP-Dexa.

    Notes: Abstract  Vinorelbine (VNB) shows high antitumoral activity in advanced breast cancer due to its high affinity for mitotic tubulin and differs from the other vinca alkaloids with regard to its low degree of neurotoxicity because of its low affinity for axonal tubulin. Preclinical data show the existence of different binding sites on tubulin for vinca alkaloids and paclitaxel (P), suggesting a lack of cross-resistance. Thus, VNB was chosen eligible for a phase II study to evaluate both the therapeutic efficacy and the toxicity of VNB in patients (pts) with advanced breast cancer failing first-or second-line chemotherapy with P. A total of 14 pts with advanced breast cancer pretreated with P were entered into the study. Therapy consisted of VNB at 30 mg/m2 diluted in 500 ml of normal saline given over 30 min after a minimal interval of 4 weeks since the last application of P. For the first four cycles, injections were repeated at 2-week intervals; thereafter they were repeated at 3-week intervals until evidence of progressive disease or severe toxicity developed. All but one pt was considered assessable for response and all pts were evaluable for toxicity. No objective response was observed; two pts showed no change in their disease. In four pts therapy had to be stopped because peripheral neurotoxicity increased from a pretherapeutic level after therapy with P from National Cancer Institute Common Toxicity Criteria (NCI-CTC) grade 1 (n=3) and 2 (n=1) to neurotoxicity grade 3 after 1, 2 (n=2), and 3 cycles of therapy with VNB, respectively. In addition, constipation of grade 2 occurred in 10 pts. Hematologic toxicity was negligible. No other evaluable toxicity exceeded NCI-CTC grade 1. Both observations of this study, the complete resistance to VNB and the increase in peripheral neuropathy, let us assume the existence of a preclinically not anticipated but clinically relevant cross-resistance between these two spindle poisons and the presence of common functional targets. Therefore, P-pretreated pts should be excluded from consecutive VNB-containing therapies.

    Notes: Abstract The two hormone analogues octreotide and goserelin have been shown to decelerate growth of human pancreatic cancer in vitro and in vivo. The objective of this pilot study was to investigate the efficacy and toxicity of the combination of these two agents in patients with advanced pancreatic cancer. Octreotide was injected subcutaneously in dosages increasing weekly, starting with 50 μg twice daily, until the level of maintenance therapy of 500 μg three times a day was reached. In addition, 3.8 mg goserelin acetate was administered subcutaneously at monthly intervals. A median of 7 cycles (range 1–27 cycles) were applied; 13 out of 14 patients entered into the study were evaluable for response and all 14 were evaluated for toxicity. In one patient with initially non-resectable pancreatic cancer, systemic therapy yielded a partial remission lasting 9 months. The degree of tumour regression then allowed a consecutive macroscopic radical tumour resection followed by an additional 6 months of no evidence of disease while the same drug combination was continued. In an additional 9 patients, no change of disease was observed, in some cases for a remarkably long time (up to 27 months). Nevertheless, the objective response rate of 7% (95% confidence interval 0±21%) was low. In 5 patients a clear improvement in their performance status was seen soon after the start of therapy; 3 patients showed progression of the disease at first evaluation or earlier and 1 patient was not evaluable at the time of study assessment. According to the product-limit method of Kaplan and Meier, the time to progression was 3.0±1.8 months [median±asymptotic standard error (ASE)] and overall survival was 6.0±1.5 months (median±ASE). Toxicity was rare and only of mild to moderate degree. Overall, the regimen under investigation did not meet the criteria for sufficient antitumoural effectiveness. Nevertheless, this study reinforces the concept that pancreatic cancer is principally responsive to endocrine therapy and therefore the further investigation of hormonal manipulation seems worth while in the future.
