Monoclonal Antibodies That Mimic the Action of Intravenous Immunoglobulin Can Inhibit Immune ThrombocytopeniaIntravenous immunoglobulin (IVIG) is prepared from large pools of plasma from healthy donors and is widely used to treat autoimmune diseases, especially immune thrombocytopenic purpura (ITP). Human polyclonal antierythrocyte antibodies, such as anti-D, can also be effective at treating ITP in individuals expressing the appropriate antigen. The demand for IVIG and anti-D exceeds the supply, and the development of a recombinant product to replace these human-derived blood products would be highly desirable. We have hypothesized that monoclonal antibodies directed against red cells may be effective in inhibiting immune forms of thrombocytopenia.

Current Management of Acute Lymphoblastic Leukemia in AdultsIntensive remission chemotherapy followed by post-remission consolidation and maintenance therapies has achieved complete remission rates of 75% to 90% and 3-year survival rates of 25% to 50% in adults with acute lymphoblastic leukemia (ALL). These results, although promising, are still less favorable than those achieved in childhood ALL. However, various novel experimental and clinical approaches show promise for improving cure rates. Also, specific therapies directed at high-risk subgroups with ALL are beginning to emerge. Detection of specific chromosomal abnormalities at diagnosis identifies patients who are at risk of failing to achieve remission, as well as those who are likely to have short, intermediate, or prolonged disease-free intervals after successful remission induction. Such prognostic information may, ultimately, be used to assign risk categories and to individualize post-remission therapy. [ONCOLOGY 9(5):433-450, 1995]

UFT/Leucovorin Plus Bolus Epirubicin and Cyclophosphamide in Advanced/Metastatic Breast CancerThis article describes the design and early results of an open-label, nonrandomized phase I/II trial of oral UFT plus leucovorin therapy in combination with bolus injections of epirubicin and cyclophosphamide in patients with advanced or metastatic breast cancer. This study was designed as a cohort dose-escalation study with the principal aims being to determine dose-limiting toxicity, overall toxicity, maximum tolerated dose, tumor response, and time to disease progression.

Current Strategies for the Immunotherapy of Multiple MyelomaHere we outline the most promising novel cellular immune strategies for patients with multiple myeloma. In addition, we highlight combinatorial approaches that, it is hoped, will further optimize cellular immunotherapies for myeloma and lead to deep and durable responses and, possibly, even cures.

Managing Early-Stage Breast Cancer in Your Older PatientsAs the aging population in the United States continues to grow, the incidence of diseases of the elderly, such as breast cancer, are increasing. Many more elderly women are expected to be diagnosed with new breast cancers, most of them in an early stage. Appropriate treatment of these women is important, as they have poorer outcomes when undertreated. In this review, we will discuss the biology and treatment of early breast cancer in elderly women. We will focus on the role of comorbidity and its effect on life expectancy, treatment decisions, current recommendations for primary treatment with surgery, radiation and neoadjuvant strategies, and adjuvant treatment including local radiation therapy and systemic treatment with endocrine therapy, chemotherapy, and newer agents. Finally we will discuss the importance of clinical trials in the elderly.

Mantle Cell Lymphoma: Clinicopathologic Features and TreatmentsMantle cell lymphoma (MCL) accounts for approximately 6% of non-Hodgkin’s lymphomas. Patients usually present with advanced disease, with a tendency for extranodal involvement. MCL is an aggressive lymphoma with moderate chemosensitivity, but it remains one of the most difficult therapeutic challenges. Complete response rates to chemotherapy range from 20% to 40%, with median survivals of 2½ to 3 years. Anthracycline-containing regimens do not prolong survival compared with nonanthracycline regimens. Single-agent rituximab (Rituxan) has produced response rates of about 30%, and when combined with an anthracycline-containing regimen, response rates increase to above 90%; however, an impact on survival has not yet been demonstrated. More intensive regimens such as hyperCVAD (hyperfractionated cyclophosphamide [Cytoxan, Neosar], vincristine, doxorubicin [Adriamycin], dexamethasone, methotrexate, cytarabine) with either stem cell transplant or rituximab have been associated with promising results.

Influenza Vaccination in Patients With Cancer: an OverviewInfluenza infection is a potential cause of additional morbidity and mortality in patients who are immunocompromised because of cancer or its treatment. Of particular note, influenza infection may delay or interrupt chemotherapy and necessitate hospitalization. Successful immunization depends on an intact immune system that can produce antibodies in response to antigen exposure. Patients with cancer often have a suppressed immune system, resulting from their disease and/or immunosuppressive therapies, and as a consequence they may have a suboptimal serologic response to influenza vaccination. Since vaccination is the only proven method for preventing influenza infection, the Advisory Committee on Immunization Practices recommends seasonal influenza vaccination for adults without contraindications who have disease- or medication-related immunosuppression. Patients with cancer should be given the trivalent inactivated vaccine. Preliminary data suggest that administering the vaccine between cycles of chemotherapy may yield the best results.

Carboplatin/Gemcitabine Combination in Advanced NSCLCThe treatment of advanced non–small-cell lung cancer (NSCLC)has evolved rapidly over the past few years. Systemic chemotherapy isassociated with both quality of life and modest survival benefit for patientswith advanced NSCLC. Platinum-based doublet combinationsare the “standard of care.” The US Food and Drug Administration(FDA) has approved gemcitabine (Gemzar), a pyrimidine analog, to beused in combination with cisplatin for the treatment of advanced NSCLCin the first-line setting. Randomized clinical trials have established comparableefficacy with improved therapeutic index for the carboplatin/gemcitabine regimen when compared with cisplatin/gemcitabine andother platinum doublets. Nonhematologic toxicities occur at a lowerfrequency with carboplatin/gemcitabine combinations compared withother “standard” platinum-based doublets, whereas dose-limitingthrombocytopenia, the most common toxicity, rarely requires therapeuticintervention. Both the 3- and 4-week schedules of carboplatin/gemcitabine result in similar efficacy and toxicity profiles, but the3-week regimen is preferred. The combination of carboplatin andgemcitabine is an effective regimen with an acceptable toxicity profilefor the treatment of advanced NSCLC. This regimen can also be usedas a foundation for the development of innovative combinations withmolecularly targeted agents.

GM-CSF and IL-2 Combination as Adjuvant Therapy in Cutaneous MelanomaCytokines have been used in the treatment of patients with cutaneousmelanoma. Granulocyte-macrophage colony-stimulating factor(GM-CSF, sargramostim [Leukine]) leads to dendritic cell/macrophagepriming and activation, and also increases interleukin-2 (IL-2)receptor expression on T lymphocytes. IL-2 creates lymphokineactivatedkiller cells and tumor-infiltrating lymphocyte cells. In thisopen-label, single-arm study of 16 high-risk patients, we combined thesetwo agents to take advantage of their different but complementary functions.All patients underwent potentially curative surgery. Postoperatively,each patient received GM-CSF at 125 μg/m2/d subcutaneously(SC) for 14 days; this was followed by IL-2 at 9 million IU/m2/d SC for4 days, and then 10 to 12 days of no treatment. In addition, patientswho had large tumors that could yield over 100 million live tumor cellsreceived autologous melanoma vaccines. The duration of follow-upranged from 21 to 42 months (median: 27 months). During follow-up,five patients developed metastases. This program was carried out on anoutpatient basis, and no hospitalization was required. It was well toleratedwith minimal side effects. The combination treatment regimen ofGM-CSF and IL-2 with or without autologous vaccine used adjuvantlyappears to benefit high-risk melanoma patients; further clinical testingof this regimen is warranted.
