We previously reported the efficacy of concurrent cisplatin (Platinol)/etoposide (PE) and radiotherapy in stage IIIB non–small-cell lung cancer in which biopsy confirmation of T4 (noneffusion) or N3 status was required (S9019). In view of the activity of docetaxel (Taxotere) as second-line therapy and potential molecular mechanisms of action favoring taxane sequencing, we designed the present study to maintain a core of concurrent PE/radiotherapy, but to substitute docetaxel consolidation for the two additional cycles of PE.

Locally advanced non–small-cell lung cancer represents 30% to 40%of all pulmonary malignancies. Most patients will die of the diseaseafter aggressive contemporary treatments. Therefore, significant improvementin therapeutic methods must be implemented to improveoverall survival rates. The arrival of a new generation of chemotherapeuticagents-including the taxanes, gemcitabine (Gemzar), andtopoisomerase inhibitors such as irinotecan (Camptosar) and topotecan(Hycamtin)-offers the hope of significant advances in the treatmentof lung cancer. Irinotecan and topotecan are camptothecin derivativesthat inhibit topoisomerase I enzyme. It is believed that topoisomerase Iinhibitors stabilize a DNA/topoisomerase I complex and interact withreplication machinery to cause cell death. A significant amount of datademonstrates that these topoisomerase I inhibitors also act asradiosensitizers. With the increasing data that support concurrentchemoradiation treatment for malignancies, including lung cancer andhead and neck cancers, there is an impetus to pursue the additionaldrugs that may potentially improve local control and survival. Irinotecanis undergoing early clinical trials in the combined-modality setting inseveral different disease sites. This paper will review the data on therole of camptothecin derivatives as a radiosensitizer and as a componentof combined-modality therapy for lung cancer. It is hoped thatnewer treatment strategies, like the combination of radiation andtopoisomerase I inhibitors, will have a significant impact on cure ratesin the future.

Androgen deprivation therapy (ADT) has been used in the management of prostate cancer for more than four decades. Initially, hormone therapy was given largely for palliation of symptomatic metastases. Following several randomized trials of patients with intermediate- to high-risk prostate cancer that demonstrated improvements in biochemical control and survival with the addition of ADT to external beam radiotherapy, there was a dramatic increase in the use of hormone therapy in the definitive setting. More recently, the safety of ADT has been questioned, as some studies have suggested an association of hormone therapy with increased cardiovascular morbidity and mortality. This is particularly worrisome in light of practice patterns that show ADT use extrapolated to situations for which there has been no proven benefit. In the setting of dose escalation with modern radiotherapy, in conjunction with the latest concerns about cardiovascular morbidity with ADT, the magnitude of expected benefit along with potential risks of ADT use must be carefully considered for each patient.

Rituximab (Rituxan) is a chimeric IgG1 anti-CD20 monoclonal antibody increasingly used in the treatment of non-Hodgkin’s lymphoma (NHL). Previous in vitro studies have suggested the role of antibody-dependent cellular cytotoxicity (ADCC) and FcgR-positive effector cells (natural killer and macrophage) in the antitumor effects of anti-CD20 antibodies, but the actual mechanism of rituximab action in vivo remains largely unknown. The FCGR3A gene coding for the FcgRIIIa receptor displays a functional dimorphism with either a phenylalanine (FCGR3A-158F) or a valine (FCGR3A-158V) at amino acid 158, with a higher affinity of human IgG1 and increased ADCC for the latter. The aim of this study was thus to determine the influence of this FCGR3A polymorphism on clinical and molecular responses to rituximab.

Rituximab (Rituxan), when combined with CHOP (cyclophosphamide [Cytoxan, Neosar], doxorubicin HCl, vincristine [Oncovin], prednisone) chemotherapy (R-CHOP) in the treatment of patients with CD20-positive diffuse large B-cell lymphoma (DLCL), significantly prolongs event-free and overall survival (GELA [Groupe d’Etude des Lymphomes de l’Adulte] LNH 98-5 study). Our objective was to estimate the cost-effectiveness of R-CHOP based on the evidence currently available.

Because irinotecan (CPT-11, Camptosar) is a topoisomerase I inhibitor with a broad spectrum of antitumor clinical activity, we investigated its activity in relapsed or refractory non-Hodgkin’s lymphomas (NHLs). Irinotecan at 300 mg/m² IV was administered every 21 days with intensive loperamide management of diarrhea.

Single-agent gemcitabine (Gemzar) is the standard of chemotherapyfor advanced pancreatic cancer, with no phase III trials to date havingshown significantly improved survival with gemcitabine-based combinationsvs single-agent treatment. The multitargeted antifolate agentpemetrexed (Alimta) shows synergistic effects in vitro in combinationwith gemcitabine, and activity and good tolerability when used as singleagenttreatment in advanced pancreatic cancer. In a phase II trial inpatients with advanced pancreatic cancer, the combination ofgemcitabine at 1,250 mg/m2 on days 1 and 8 plus pemetrexed at 500mg/m2 on day 8 after gemcitabine every 21 days resulted in a mediansurvival of 6.5 months and a 1-year survival rate of 29%. Neutropeniawas the primary toxicity, with grade 4 toxicity in 51% of patients. Thepromising results of this trial prompted the initiation of a phase IIItrial comparing gemcitabine at 1,000 mg/m2 on days 1, 8, and 15 every28 days vs the 21-day gemcitabine/pemetrexed regimen given with vitaminsupplementation in patients with pancreatic cancer. The primaryoutcome measure was overall survival, with secondary measures includingresponse rate, progression-free survival, and quality of life.While an increase in response and time to progression was reported forthe gemcitabine/pemetrexed combination, there were no significantdifferences in survival between treatment arms.

After pegylated liposomal doxorubicin (PEG-LD) (Doxil) was shown to be active in ovarian tumors, several trials were developed at the University of Southern California to determine its safety and efficacy in a variety of gynecologic and peritoneal malignancies. Completed phase I and phase II trials have found PEG-LD to be safe and effective in the treatment of platinum- and paclitaxel-refractory epithelial ovarian carcinoma. A new phase II trial is currently underway in similarly refractory patients with ovarian and other related cancers and various degrees of pretreatment. In addition, the efficacy of PEG-LD is being explored in combination with paclitaxel (Taxol), with cisplatin, and with hyperthermia. [ONCOLOGY 11(Suppl 11):38-44, 1997]
