Cytostatic chemotherapy of hematological malignancies if often complicated by
neutropenia
, which increases the risk of infections, especially if the neutrophil count is below 500/ml. Frequently, fever is the first and in most patients the only sign of an infection. Unexplained fever is defined as follows: temperature of > or = 38.3 degrees C or > or = 38.0 degrees C for at least one hour, or measured twice within 12 hours, if the neutrophil count is < 500/ml or < 1.000/ml with predicted decline to 500/ml. Different risk categories can be identified according to the duration of
neutropenia
: low risk < or = 5 days, intermediate risk 6-9 days, high risk > or = 10 days. An empirical mono- or duotherapy with antipseudomonal and antistreptococcal agents should be initiated immediately. In the low risk patient group, oral therapy with cipro-, levo-, or ofloxacin combined with amoxicillin/clavulanic acid is permissible. For standard and high risk patients, monotherapy can be carried out with either ceftazidime, cefepime, piperacillin with a beta-lactam-inhibitor or a carbapenem. In
duo
-therapy, a single dose of an aminoglycoside is combined with acylaminopenicillin or a cephalosporin of the third or fourth generation. The addition of glycopeptides in empirical therapy should only be considered in the presence of severe mucositis, or if a catheter-associated infection is suspected. If fever persists after 72-96 hours of first-line therapy with antibiotics, the regimen should be modified (with the exception of e.g. coagulase-negative staphylococci infections, because these infections take longer to respond). Intermediate risk patients should additionally receive an aminoglycoside after monotherapy (penicillin or a cephalosporin). If a carbepenem was administered for monotherapy, this can be followed by a quinolone and/or a glycopeptide. In the high risk group, the same modifications should be made as in the intermediate risk group but with additional systemic antifungal treatment. In the presence of unexplained fever, fluconazole can be administered at first, but if this fails, amphotericin B (conventional or liposomal), voriconazole, itraconazole or caspofungin should be started. After defervescence to < 38 degrees C, treatment should be continued for seven days if the neutrophil count is < 1.000/ml, and for two days if the neutrophil count is > 1.000/ml. In documented infections treatment is directed against the responsible pathogen, however maintaining the broad spectrum activity. Lung infiltrates are often caused by fungal organisms, therefore an empiric antifungal therapy is necessary which is active against Aspergillus species. Antibacterial prophylaxis can reduce the incidence of bacterial infections, but not the mortality by infections. If the risk of fungal infections exceeds 15%, an antifungal prophylaxis with resorbable drugs can be given.

In advanced or relapsed pancreatic cancer, mono- or
duo
-therapy has shown modest efficacy at best. The present study evaluated the efficacy of a triplet combination in relapsed or advanced pancreatic cancer. A total of 37 patients with adenocarcinoma of the pancreas in stage III/IV or with relapsed disease were treated with a gemcitabine, 5-fluorouracil and cisplatin (GFP) regimen every 3 weeks. Only 29 out of 37 patients were evaluable for response due to early treatment interruption in 8 patients. The overall response rate was 24.1% and the disease control rate was 68.9%. The progression-free survival (PFS) rate was 61.5, 30.9 and 17.6% at 3, 6 and 9 months, respectively, and the overall survival (OS) rate was 46.5 and 30.6% at 6 and 12 months, respectively. Grade 3/4 leukopenia,
neutropenia
and thrombocytopenia occurred in 18.4, 29.9 and 24.5% of 147 cycles, respectively. Old age and a poor performance status (PS) were associated with the early discontinuation of chemotherapy (P=0.038 and P=0.036, respectively). In patients <65 years old and with a PS of <2, the median PFS and OS times were 5.3 months and 10.3 months, respectively. Overall, although GFP resulted in acceptable response and survival rates, it does not appear to have marked superiority to gemcitabine-based single or duplet chemotherapy.
