Management of Follicular Lymphoma in the Up-Front and Relapsed SettingsA number of recent treatment advances in the management of follicular lymphoma (FL), including the introduction of the anti-CD20 monoclonal antibody rituximab, have effectively shifted the primary therapeutic goal away from palliation and avoidance of toxicity toward the more proactive objective of extending survival. This paper reviews recent practice patterns in the broad context of the published findings from major phase III randomized trials; it documents potential gaps between trial results and actual practice, and the implications of these for continuing education of oncologists. Forty-three US-based community oncologists participated in a cross-sectional case survey during which 40 documented their management of 186 patients with newly diagnosed FL and 133 patients with relapsed FL, all of whom were treated after January 1, 2008. The findings from this initiative indicate that the majority of these patients did not have any major symptoms at presentation. Additionally, tolerance of and response to treatment, regardless of the regimen employed, were similar across the different age groups studied (<65, 65-74, ≥75 years). Therapies selected by the physicians surveyed in both the up-front and the relapsed settings broadly corresponded to the evidence-based published literature and were supported by treatment guidelines. In addition, a change in the proportional use of bendamustine/rituximab (BR) in the up-front treatment of FL from 2008 to 2010 was observed, suggesting that community oncologists are rapidly incorporating pivotal clinical trial results when deciding on individual patient management strategies.

Topoisomerase I Inhibitors in Small-Cell Lung CancerAmong patients with lung cancer, approximately 15% have smallcelllung cancer (SCLC). The clinical characteristics of SCLC tend tobe more aggressive, but also more sensitive to chemotherapy and radiationtherapy than those of non-SCLC. Irinotecan (Camptosar) is aderivative of camptothecin, an inhibitor of the nuclear enzymetopoisomerase I. Irinotecan has been shown to exhibit excellent antitumoractivity against SCLC in monotherapy regimens and in combinationwith cisplatin. A phase III trial comparing irinotecan and cisplatin(IP) with etoposide and cisplatin (EP) in patients with previously untreatedextensive-stage SCLC (ED-SCLC) was conducted. Patients inthe IP arm responded significantly better than patients in the EP arm.In the IP arm, the response rate was 84%, and median overall survivalwas 12.8 months. A phase II trial of irinotecan, cisplatin, and etoposide(IPE) administered weekly (arm A) or every 4 weeks (arm B) for EDSCLC(JCOG 9902-DI) was also performed. In arm B, the responserate was 77% and the median overall survival was 12.9 months. A randomizedtrial comparing IP with IPE administered every 3 weeks inpatients with previously untreated ED-SCLC is presently being performedin Japan.

Phase I Trial of Irinotecan and Epirubicin in Advanced CancerBoth irinotecan (CPT-11, Camptosar) and epirubicin (Ellence) are significant chemotherapeutic agents that are used in the management of many different cancers. Each agent works through the inhibition of topoisomerases, and inhibition of topoisomerases I and II may possibly result in significant clinical synergy. This phase I clinical study represents an investigation of the first combination of irinotecan and epirubicin in patients with advanced cancer.
