The aim of this study was to assess whether the reduction in the total dose of pegylated liposomal doxorubicin (PLD) per cycle from 50 mg/m(2) every 4 weeks to 40 mg/m(2) every 4 weeks can effectively lower the incidence of treatment-related palmar-plantar erythrodysesthesia (PPE) and mucositis. ⋯ The favorable safety profile observed in this study leads us to recommend the use of PLD 40 mg/m(2) every 4 weeks for patients with advanced breast cancer.

The combined assessment of thymidylate synthase (TS), dihydropyrimidine dehydrogenase (DPD) and thymidine phosphorylase (TP) gene expressions in metastatic colorectal cancer has been reported to be able to predict the efficacy of fluoropyrimidine-based chemotherapy. In order to evaluate the prognostic role in the adjuvant setting, we investigated the TS, DPD and TP expression in primary tumors of colorectal cancer patients treated with 5-fluorouracil (5-FU). ⋯ This retrospective investigation suggests that the combined assessment of TS and DPD may be useful to evaluate the prognosis of patients with Dukes' B and C colon carcinoma receiving 5-FU adjuvant chemotherapy. The role of TP as a predictor for 5-FU-based therapy needs further investigations.

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.

A phase I study was conducted to determine the maximum tolerated doses (MTDs) and dose-limiting toxicities (DLTs) of the pegylated liposomal doxorubicin (PLD) and oxaliplatin combination in patients with advanced solid tumors. ⋯ The combination of PLD and oxaliplatin has an acceptable toxicity profile with promising activity and merits further evaluation in phase II studies.
