Randomized Controlled Trial Multicenter Study Clinical Trial
A randomised multicentre trial of modified CHOP versus MCOP in patients aged 65 years and over with aggressive non-Hodgkin's lymphoma.
The aim of this study was to determine in a randomised trial whether there is any significant difference in toxicity between modified CHOP and MCOP chemotherapy in elderly patients with aggressive non-Hodgkin's lymphoma (NHL) and to determine whether this reduced dose chemotherapy can be administered with full dose intensity, low toxicity and produce acceptable survival. ⋯ This multicentre randomised trial provides further information on the dose intensity achievable with CHOP or MCOP regimens in elderly patients (median age 74 years) with aggressive NHL. These dose-reduced regimens can be given with nearly 100% dose intensity with 65% of patients completing all the treatment. Survival is comparable to that observed with the more intensive regimens given in this age group.

The clinical characteristics of nail changes in seven patients receiving taxane-containing chemotherapy are described. They include nail pigmentation, subungual hematoma, Beau's lines and onycholysis and subungual suppuration. The incidence of such changes (ranging from 0% to 44%) is reviewed from a Medline search of the literature.

We have treated 38 transplant-eligible patients with relapsed/refractory non-Hodgkin's lymphoma and Hodgkin's disease using an outpatient-based regimen of ifosfamide, carboplatin and etoposide (ICE) for both salvage and peripheral blood stem cell mobilisation. Patients included relapsed or refractory diffuse large B-cell lymphoma (n = 17), follicular lymphoma (n = II), T-cell lymphoma (n = 2), mantle cell lymphoma (n = 2) and Hodgkin's disease (n = 6). Seven patients with diffuse large B-cell lymphoma and three patients with follicular lymphoma (26%) were considered chemorefractory. ⋯ Follow-up is short: however, the Kaplan-Meier estimate of the proportion of patients alive and event-free at a median follow-up of 11 months is 80% and 59%, respectively. Event-free survival for patients who achieved a CR after ICE and transplantation is 88% versus 45% for those who achieved a PR. These data confirm the efficacy and tolerability of fractionated ICE chemotherapy as both a salvage and mobilisation regimen that can be readily delivered in an outpatient setting.

Comment Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
A randomized double-blind multicenter phase III study of fixed-dose single-administration pegfilgrastim versus daily filgrastim in patients receiving myelosuppressive chemotherapy.
We evaluated the efficacy of a single fixed 6 mg dose of pegfilgrastim (a pegylated version of filgrastim) per cycle of chemotherapy, compared with daily administration of filgrastim, in the provision of neutrophil support. ⋯ A single fixed dose of pegfilgrastim administered once per cycle of chemotherapy was comparable to multiple daily injections of filgrastim in safely providing neutrophil support during myelosuppressive chemotherapy. Pegfilgrastim may have utility in other clinical settings of neutropenia.

Phase I/II studies suggest that the combination of irinotecan with capecitabine is feasible and has promising activity. Diarrhea and neutropenia are dose limiting. Overall response rates (RRs) in the 40% to 60% range are seen from preliminary data. ⋯ Following evidence that COX-2 inhibition can slow progression in familial adenomatous polyposis, celecoxib is to be studied in metastatic colorectal cancer (CRC). In vitro, the cyclin-dependent kinase inhibitor flavopiridol enhances the induction of apoptosis by chemotherapy. Clinically, it can safely be administered with irinotecan, and studies in CRC are planned.
