New Questions About Transplantation in Multiple MyelomaMultiple myeloma is now the most common indication for autologous stem cell transplantation (ASCT) in North America, with over 5,000 transplants performed yearly (Center for International Blood and Marrow Transplant Research [CIBMTR] data). While the role of ASCT as initial therapy in multiple myeloma has been established by randomized studies, newer therapies are challenging the traditional paradigm. The availability of novel induction agents and newer risk stratification tools, and the increasing recognition of durability of remissions are changing the treatment paradigm. However, even with arduous therapy designed to produce more complete remissions—for example, tandem autologous transplants—we have seen no plateau in survival curves. A tandem autologous procedure followed by maintenance therapy may be performed in an attempt to sustain remission. Sequential autologous transplants followed by nonmyeloablative allotransplants are pursued with the hope of "curing" multiple myeloma. We examine how the key challenges of increasing the response rates and maintaining responses are being addressed using more effective induction and/or consolidation treatments and the need for maintenance therapies after ASCT. We argue that given the biologic heterogeneity of multiple myeloma, risk-adapted transplant approaches are warranted. While the role of curative-intent, dose-intense toxic therapy is still controversial, conventional myeloablative allogeneic transplants need to be reexamined as an option in high-risk aggressive myeloma, given improvements in supportive care and transplant-related mortality.

Management of Anemia in Patients With Hematologic MalignanciesAnemia is common in patients with hematologic malignancies, and it has negative effects on their quality of life. The current clinical practice guidelines recommend erythropoietic therapy in patients with cancer- or chemotherapy-related anemia, but anemia is often undertreated in patients with hematologic malignancies. Several randomized controlled trials have shown that treatment with erythropoiesis-stimulating proteins such as epoetin alfa (Procrit), epoetin beta, and darbepoetin alfa (Aranesp) increases hemoglobin levels, reduces the need for red blood cell transfusions, and improves quality of life in patients with hematologic malignancies and anemia receiving chemotherapy. Furthermore, preliminary data from a recent open-label study suggest that early treatment of mild anemia in patients with hematologic malignancies treated with chemotherapy produces marked improvements in quality of life and productivity. Increasing patients' hemoglobin levels may also improve their cognitive function. These findings support the use of erythropoietic therapy to manage anemia in patients with hematologic malignancies who are treated with chemotherapy.

Guidelines for the Use of Erythropoietic Growth Factors in Patients With Chemotherapy-Induced AnemiaThe use of erythropoietic growth factors to treat chemotherapy-induced anemia (CIA) has been increasing as clinicians become more aware of the ability of these drugs to improve the quality of life of patients with cancer. The cost associated with erythropoietic growth factor therapy makes its appropriate use a practical issue for physicians and hospitals. Clinical practice guidelines can benefit physicians by increasing practice efficiency, reducing medical errors, increasing the quality of medical care, and decreasing reimbursement problems. The American Society of Clinical Oncology and the American Society of Hematology, the European Organisation for Research and Treatment of Cancer, and the National Comprehensive Cancer Network (NCCN) have all published guidelines for using erythropoietic growth factors to treat CIA, and this article reviews and summarizes those guidelines. Of the three guidelines for the use of erythropoietic growth factors in CIA, the NCCN guidelines are based on the most recent data. Current evidence indicates that erythropoietic growth factors can increase hemoglobin levels, reduce the need for red blood cell transfusions, and improve quality of life; the effect of erythropoietic therapy on outcomes in patients with CIA is still being investigated.

Commentary (Goldman)-Chronic Myeloid Leukemia: Changing the Treatment ParadigmsMolecular discoveries and clinical advances over the past few decades have made the treatment of chronic myeloid leukemia (CML) one of the great success stories of modern medicine. Before the 1980s, the focus was on maintaining normal white blood cell counts with agents such as hydroxyurea and busulfan. With the use of interferon, treatment strategies turned more toward cytogenetic remission. In 1998, targeted therapy was introduced to this setting with the first studies of imatinib mesylate. Since then, treatment objectives have shifted toward the attainment of molecular remission. In this review, we consider the variety of approaches to treating CML, efforts to minimize treatment failures, and possible future directions in therapy.

Commentary (Harari): Anti-EGFR Therapy UpdateSince initial characterization over 40 years ago, strong preclinical and clinical data have clearly established the epidermal growth factor receptor (EGFR) as a worthy molecular target for intervention in cancer therapy. The receptor is expressed, overexpressed, or mutated in many human tumors, including head and neck, colorectal, pancreatic, non-small-cell lung, ovarian, esophageal, gastric, breast, prostate, bladder, and renal cancers. Experiments in several model systems have confirmed that EGFR signaling is involved in regulating several key biologic processes, including cell proliferation, epithelial development, organogenesis, apoptosis, angiogenesis, and differentiation. Furthermore, EGFR function has been shown to be altered and/or dysregulated in a variety of spontaneous tumors.

Treatment of Stage I-III Non-Small-Cell Lung Cancer in the ElderlyElderly patients with stage I-III non-small-cell lung cancer (NSCLC) constitute a peculiar patient population and need specific therapeutic approaches. Limited resections are an attractive alternative for elderly patients with resectable NSCLC because of the potential reduction in postoperative complications. Curative radiation therapy is an acceptable alternative for elderly patients who are unfit for or refuse surgery. Hypofractionated stereotactic body radiation therapy is of particular interest for this population because of its favorable tolerance.

New Treatments for Multiple MyelomaIn 2004, multiple myeloma was diagnosed in more than 15,000 peoplein the United States and will account for approximately 20% of deathsdue to hematologic malignancies. Although traditional therapies suchas melphalan (Alkeran)/prednisone, combination chemotherapy withVAD (vincristine, doxorubicin [Adriamycin], and dexamethasone), andhigh-dose chemotherapy with stem cell transplantation have shownsome success, median survival remains between 3 to 5 years. Treatmentoptions for patients with multiple myeloma have increased in recentyears, with the promise of improvement in survival. New agents, suchas the proteasome inhibitor bortezomib (Velcade), the antiangiogenicand immunomodulator thalidomide (Thalomid) and its analogs, suchas lenalidomide (Revlimid), together with other small molecules, includingarsenic trioxide (Trisenox), and other targeted therapies, havebeen studied alone and in combination with other antineoplastic therapies,either as induction therapy prior to stem cell transplantation or inpatients with relapsed disease. Bortezomib recently was approved inthe United States for the treatment of multiple myeloma in patientswho have received at least one prior therapy. The use of bortezomibbasedregimens as front-line therapy as well as the use of other agentsin multiple myeloma remain under investigation, and approvals forboth thalidomide and lenalidomide are hoped for soon, with the overallprospect of patient outcome continuing to be increasingly positive.

Adjuvant Chemotherapy for Resected Non–Small-Cell Lung CancerBecause of the high rate of distant disease recurrence, the 5-yearsurvival of patients who have undergone complete surgical resectionof localized non–small-cell lung cancer (NSCLC) is approximately 50%.Initial results from early studies of adjuvant postoperative chemotherapyreported an adverse effect of alkylating agent and older chemotherapyregimens on survival. Cisplatin-based combinations were the first toshow a survival advantage. A 1995 meta-analysis of these studies suggesteda 13% reduction in the hazard ratio for death (HR = 0.87), leadingto a 5% survival benefit at 5 years. Still, these trials involved limitednumbers of patients (N = 1,394), and the results failed to reach statisticalsignificance (P = .08). Of the five largest subsequent randomizedtrials of platinum-based adjuvant therapy, three showed a significantsurvival advantage. Although it is impossible to determine the reasonsfor the differing outcomes of these studies, several key features distinguishthem, and the data suggest that medically fit patients with resectedstage IB or II NSCLC should be offered chemotherapy with a platinum/new drug combination.

Commentary (Stinchcombe et al): Perspectives on Salvage Therapy for Non–Small-Cell Lung CancerWe applaud Dr. Cappuzzo andcolleagues for an excellentreview of an emerging fieldin lung cancer treatment. Since 2000,three drugs (docetaxel [Taxotere],pemetrexed [Alimta], and erlotinib[Tarceva]) have been approved by theUS Food and Drug Administration(FDA) for second-line therapy in non–small-cell lung cancer (NSCLC) basedon the results of phase III trials (seeTable 1).[1-4] It is also possible thatsimilar approval will be sought for otherdrugs (eg, topotecan [Hycamtin]),[5]and gefitinib (Iressa) remains an optionfor treatment in the third-line setting.

Perspectives on Salvage Therapy for Non–Small-Cell Lung CancerPlatinum-based chemotherapy offers a modest survival advantage overbest supportive care in chemotherapy-naive patients with a good performancestatus and advanced/metastatic non–small-cell lung cancer(NSCLC). Despite the survival benefit associated with first-line chemotherapy,the majority of patients will experience relapse or disease progression.In clinical practice, an increasing number of patients maintaina good performance status after first-line treatment and are eligible forfurther treatments. Docetaxel (Taxotere) at 75 mg/m2 given once every3 weeks has been the standard of care for second-line chemotherapy sincethe year 2000. Pemetrexed (Alimta) is a novel multitargeted antifolateagent with single-agent activity in first- and second-line treatment ofNSCLC. A large phase III study comparing docetaxel to pemetrexed insecond-line therapy demonstrated that pemetrexed is equally active andless toxic than docetaxel. Based on these results, pemetrexed is a reasonablesecond-line chemotherapy option for patients with recurrent, advancedNSCLC. Progress made in the field of molecular biology has led to theidentification of drugs active against specific cellular targets. Gefitinib(Iressa) and erlotinib (Tarceva) are both orally active tyrosine kinase inhibitorsof the epidermal growth factor receptor. Phase II and III trialshave demonstrated that these agents are active particularly in a subgroupof patients with specific biologic characteristics. Both drugs have beenapproved for the treatment of pretreated NSCLC. Other drugs, such ascetuximab (Erbitux) and bevacizumab (Avastin) have shown promisingactivity in NSCLC and are currently being tested in clinical trials.
