Recombinant granulocyte colony-stimulating factors (G-CSF) have been shown to be effective in reducing the risk of infections associated with antitumour chemotherapy. This report describes a single-centre experience of the efficacy of pegfilgrastim compared with filgrastim or lenograstim in reducing the incidence of febrile neutropenia in patients receiving combination chemotherapy with taxane and epirubicin in a neoadjuvant and adjuvant setting. ⋯ These data show a trend towards superiority of pegfilgrastim over filgrastim or lenograstim in reducing the frequency of febrile neutropenia in patients treated with taxane and epirubicin chemotherapy regimens for breast cancer.

Various chemotherapeutic agents as well as the anti-CD20 antibody rituximab (R) have been tested in patients with mucosa-associated lymphoid tissue (MALT) lymphoma, but no standard chemotherapeutic regimen has emerged so far. Judging from the data obtained in various types of lymphoma, the activity of R appears to be enhanced by combination with chemotherapy. As no data on this topic exist for MALT lymphoma, we have retrospectively analysed our experience with R plus cyclophosphamide, doxorubicin/mitoxantrone, vincristine and prednisone (R-CHOP/R-CNOP) in patients with relapsed MALT lymphoma. ⋯ Our data demonstrate a high activity of R-CHOP/R-CNOP in relapsing MALT lymphoma irrespective of prior therapy.

Malignant gastrointestinal stromal tumours (GISTs) are a rare subset of aggressive mesenchymal tumours specific to the gastrointestinal system. They are both locally aggressive and can metastasize. The aim of this analysis was to report on our experience of the utility of coincidence positron emission tomography (co-PET) based on an 18F-FDG gamma camera in assessing treatment response to imatinib using CT as the comparator and the final clinical outcome as the end point. ⋯ 18F-FDG co-PET is a useful modality to monitor treatment response to imatinib in patients with malignant GIST. Although there is a relatively reduced sensitivity when compared with CT for the detection of lesions especially in the liver, co-PET changes in several instances precede the changes on CT scanning. This modality has the potential to influence clinical decision making and should be considered as part of the standard care of patients on imatinib.
