Docetaxel for Locally Advanced or Metastatic Non-Small-Cell Lung Cancer
June 1st 2002Docetaxel (Taxotere) has shown activity both as a single-agent and in combination with multiple other cytotoxic agents in the front-line therapy of advanced, metastatic non-small-cell lung cancer (NSCLC). A randomized, phase III trial demonstrated a survival advantage for docetaxel over best supportive care in the front-line setting, with docetaxel achieving a 2-year survival of 12% vs 0% for best supportive care. Combinations of docetaxel with the platinum agents have been the most extensively studied in the front-line setting and have produced notably high response rates and encouraging median survivals.
Gene Chip Identifies Risk of Relapse in Children With ALL
May 1st 2002ORLANDO-A gene-profiling chip might help identify children with acute lymphoblastic leukemia (ALL) who are at low risk of relapse and could be spared intensive therapy, or who are at high risk for treatment-induced acute myeloid leukemia (AML) and should not be treated with topoisomerase II inhibitors.
Normalizing Hemoglobin Predicted to Slow Progression of Chronic Inflammatory Diseases
May 1st 2002LOS ANGELES-Progress in treating cancer-related anemia has accelerated in the almost 20 years since the human erythropoietin gene was cloned. That was in 1983. Ten years later, the Food and Drug Administration approved epoetin alfa (Epogen, Procrit) for transfusion-preventing treatment of patients with anemia-complicating therapy.
Targeted Therapy in Squamous Cell Cancers of the Head and Neck
May 1st 2002The 5-year survival of patients with locally advanced squamous cell cancers of the head and neck is still less than 30%. Treatment of these cancers involves significant functional impairment, diminished quality of life, and considerable time and expense. Local recurrence and distant metastases are still fairly common, and the development of second primary cancers has a significant impact on survival in patients with initial early-stage disease. Despite the success of combination chemoradiation in locally advanced head and neck cancers, these facts stress the need for improved treatment of this disease.
The Role of Mitoxantrone in Non-Hodgkin’s Lymphoma
April 1st 2002Dr. Armitage presents a succinct and thorough review of the role of mitoxantrone (Novantrone) in patients with non-Hodgkin’s lymphoma (NHL). He begins by emphasizing the importance of accurate diagnosis as described in the World Health Organization classification which evolved from the Revised European American Lymphoma classification. Both of these present day classifications are based on the immunologic principles separating lymphomas into B- and T-cell disorders developed in the 1970s by Lennert, Lukes, and Collins.[1,2] His review addresses multiple issues in mitoxantrone therapy, including dose intensity, cardiotoxicity, combination therapy with nucleoside analogs in low-grade lymphomas, the impact of rituximab (Rituxan), therapy for acquired immunodeficiency syndrome (AIDS)-related lymphoma, and the role of high-dose mitoxantrone as part of a preparative regimen for autologous transplants.
Five-Fraction Palliative Radiotherapy May Improve NSCLC Survival
April 1st 2002SAN FRANCISCO-Patients with inoperable non-small-cell lung cancer (NSCLC) who receive 20 Gy of radiation therapy in five fractions achieved slightly superior palliation of thoracic symptoms than those receiving a single 10-Gy dose, according to a study presented at the 43rd Annual Meeting of the American Society for Therapeutic Radiology and Oncology (abstract 30). An unexpected finding was that patients receiving the five-fraction therapy survived significantly longer, the study authors said.
Irinotecan Therapy for Small-Cell Lung Cancer
April 1st 2002Dr. Alan Sandler’s sweeping review of the role of irinotecan (CPT-11, Camptosar) in the treatment of small-cell lung cancer (SCLC) leaves few stones unturned. Some perspective, however, is necessary. To date, with the exception of the Japan Clinical Oncology Group trial, which demonstrated the superiority of irinotecan in combination with cisplatin compared to standard therapy with etoposide and cisplatin, no other new platinum agent combination has proven superior to standard therapy in the treatment of extensive SCLC.[1] The Noda study, published recently in the New England Journal of Medicine, has sparked considerable interest and anticipation in the medical oncology community.
Current Clinical Trials of Molecularly Targeted Agents in Children With Cancer, Part 2
A number of molecularly targeted agents directed at critical cell survival and cell proliferation pathways have recently entered clinical evaluation in children with cancer. These agents offer the potential for more effective anticancer therapy while simultaneously diminishing acute and long-term toxic effects. Systematic evaluations of targeted agents are essential to achieving continued improvements in outcome for children with cancer. Brief summaries of the rationale for conducting studies of several agents in children are provided below. Following these summaries is a listing of phase I, phase I/II, phase II, and pilot studies of these and other agents in pediatric populations.
Commentary on Abstracts #1535, #3354, and #3030
March 1st 2002Increasing data suggest that rituximab may have activity in a variety of uncommon B-cell malignancies. Although earlier preliminary data suggested a high response rate in hairy cell leukemia (HCL) (Thomas et al: Blood 94:705a[abstract 3116], 1999), the complete response rate of 20% in patients who had previously failed cladribine (Leustatin) therapy reported by Nieva et al was considered disappointing (abstract #1535). A more promising approach to patients with refractory HCL is the BL-22 immunotoxin, in which anti-CD22 is linked to a Pseudomonas exotoxin (Kreitman et al: N Engl J Med 345:241-247, 2001). Of 16 patients treated on a phase I study who had failed at least one purine analog, 13 responded, including 11 complete remissions. At a median of 16 months, only three complete responders relapsed and these were successfully reinduced.
High-Dose Therapy in Mantle Cell Lymphoma
March 1st 2002ORLANDO-High-dose therapy with stem cell support improves event-free survival in patients with mantle cell lymphoma when performed in first remission, according to results of a European Intergroup study presented at the 41st Annual Meeting of the American Society of Hematology (abstract 3572).
Rituximab Improves Paclitaxel/Topotecan Salvage Efficacy in NHL
March 1st 2002ORLANDO-Adding rituximab (Rituxan) to paclitaxel (Taxol)/topotecan (Hycamtin) salvage therapy raises response rates by about 25%, more than triples complete response rates, and is effective in both primary refractory and relapsed aggressive B-cell lymphomas.
Current Clinical Trials of Molecularly Targeted Agents in Children With Cancer

These agents offer the potential for more effective anticancer therapy while diminishing acute and long-term toxic effects. Systematic evaluations of agents such as these are essential if continuing improvements in outcome are to be achieved in children with cancer. Brief summaries of the rationale for conducting studies of several agents in children are provided below. Following these summaries is a listing of phase I, phase I/II, phase II, and pilot studies of these agents in pediatric populations
SMART Studies Two HAART Strategies for HIV
March 1st 2002BETHESDA, Maryland-A long-term study to determine which of two common strategies is better for treating HIV-infected individuals was initiated in January, as 21 US centers and several Australian sites began enrolling the first 1,000 patients. Participants in the SMART trial (Strategies for Management of Anti-Retroviral Therapies) are randomized to receive immediate, aggressive antiretroviral therapy ("hit-hard-early") or no HIV drugs until CD4+ T-cell counts fall below 250 cells/µL ("go-slow").
Allovectin-7 Immunotherapy Active in Metastatic Melanoma
March 1st 2002NEW YORK-In patients with metastatic cutaneous melanoma who have already failed or are refractory to standard treatment, Allovectin-7, a targeted gene therapy using a nonviral delivery system, can induce both local and systemic responses in tumors injected weekly, results of a multicenter phase II study suggest.
Treatment of Acute Myelogenous Leukemia
March 1st 2002There have been significant advances in our understanding of the biology of acute myelogenous leukemia (AML), and to a lesser extent, in its treatment. Dr. Estey has provided an excellent overview of the current state of the clinical management of the disease. He has described both the standard therapeutic approaches, including allogeneic hematopoietic stem cell transplantation, as well as the role of investigational therapy. The present state of clinical research in AML is reviewed in some detail in the context of the broad clinical investigation of the disease at the M. D. Anderson Cancer Center. Dr. Estey makes a strong argument for the early consideration of investigational therapy, focusing on patients for whom "standard" therapy is demonstrably inadequate.
Selection for Herceptin by FISH Improves Survival
February 1st 2002SAN ANTONIO-A retrospective study presented at the 24th Annual San Antonio Breast Cancer Symposium (abstract 18) has shown that breast cancer patients selected for treatment with trastuzumab (Herceptin) combination therapy on the basis of HER-2 gene amplification by fluorescent in situ hybridization (FISH) may have improved clinical benefits.
Role of Adjuvant Therapy in Resected Stage II/IIIA Non-Small-Cell Lung Cancer
January 1st 2002The search for effective postoperative adjuvant therapy for patients with resected non-small-cell lung cancer (NSCLC) has been spurred by a high rate of failure after definitive surgery. Except for patients with resected T1, N0, M0 lesions, failure rates exceed 30%. Widespread application of adjuvant therapy has been reined in by a disappointing lack of effectiveness in this setting.
ODAC Backs Adding HER-2 DNA Test to Herceptin Package Insert
January 1st 2002SILVER SPRING, Maryland-The FDA’s Oncologic Drugs Advisory Committee (ODAC) has unanimously recommended that the agency amend the labeling of Herceptin (trastuzumab, Genentech) to include a new gene-detection test to identify women with metastatic breast cancer who are likely to benefit from the therapy. The 16-to-0 vote backed adding the PathVysion HER-2 DNA Probe Kit to the labeling. The kit is made by Vysis, Inc., now owned by Abbott Laboratories.
Antifungal Prophylaxis in Hematopoietic Stem Cell Transplant Recipients
November 1st 2001Efforts at preventing and treating fungal infection in hematopoietic stem cell transplant (HSCT) recipients must take into account the types of infections likely to be encountered during the different risk periods in hosts with different underlying risks. Given the emergence of molds as prevalent pathogens and the long duration of risk in allogeneic HSCT recipients, optimal antifungal prophylaxis would consist of treatment that can be given over a prolonged period and that would provide both anti-Candida and anti-Aspergillus activity. Optimal empiric therapy would consist of a broad-spectrum agent in the absence of more sensitive and specific methods for microbial diagnosis. Fluconazole (Diflucan) is currently the standard prophylactic agent for candidiasis, although mold-active agents and alternative strategies for polyene administration are being investigated. The gold standard for empiric therapy is currently a polyene antifungal, yet an increased appreciation for amphotericin B-resistant yeasts and molds, and less toxic mold-active alternatives, might lead to the use of other compounds in the future. The recent development of multiple alternatives emphasizes our need to establish treatment algorithms that consider both the likely pathogens and potential toxicities.

Gene Therapy Plus Radiotherapy Delays Esophageal Cancer Growth in Mice
November 1st 2001WASHINGTON-Combining gene therapy with radiotherapy may provide a useful approach to combating human esophageal cancers, said Vinay Kumar Gupta, MD, of the University of Chicago Medical School, at the 54th Annual Cancer Symposium of the Society of Surgical Oncology.
Three Platinum-Based Doublets for NSCLC Tested in Italy
October 1st 2001SAN FRANCISCO-Platinum-based chemotherapy with either gemcitabine (Gemzar) or paclitaxel (Taxol) caused fewer terminations of therapy for progressive disease or adverse events than the reference regimen of platinum with vinorelbine (Navelbine) in advanced non-small-cell lung cancer (NSCLC).
