Irinotecan in Relapsed or Refractory Non-Hodgkin’s LymphomasBecause 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.

Controversies in Early-Stage Hodgkin’s DiseaseThe optimal choice of treatment for early-stage Hodgkin’s disease depends on (1) knowledge of the prognostic factors that may influence treatment outcome and (2) the risk of acute and long-term complications incurred by treatment. For prognostic and therapeutic considerations, patients are divided into those with early-stage, favorable-prognosis disease (clinical stage I/II without risk factors) and those with early-stage, unfavorable-prognosis or intermediate-stage disease (clinical stage I/II with risk factors).

DNA Microarrays in Lymphoid MalignanciesGene expression profiling using cDNA microarrays has the potentialto improve current lymphoma classification schemes by establishinga molecular diagnosis of these malignancies. The use of this technologyled to the discovery of biologically and clinically distinct subtypesof diffuse large B-cell lymphoma (DLBCL). Gene expression datacan also be used to formulate powerful mathematical algorithms thatpredict the clinical outcome in patients with DLBCL and mantle celllymphoma. In B-cell chronic lymphocytic leukemia, gene expressionprofiling identified ZAP70, an important prognostic marker whose expressioncorrelates with the mutational status of the immunoglobulinheavy chain gene and, therefore, with survival in these patients. Theseexamples illustrate that gene expression profiling may pave the way fordetailed molecular characterization of lymphoid malignancies that willultimately lead to tailored, disease-specific therapies.

Neoadjuvant Therapy With Gemcitabine in Breast CancerPrimary systemic therapy (ie, preoperative or neoadjuvant) increasesthe possibility for breast-conserving surgery in patients with primarybreast cancer. Patients with pathologic complete response to primarysystemic therapy have improved survival compared with those with persistenttumors. Several phase II trials have evaluated gemcitabine-containingdoublet or triplet regimens as primary systemic therapy for breastcancer, results of which have shown promising clinical and pathologicresponse rates with manageable toxicity. Results of a phase I/II studyof gemcitabine (Gemzar)/epirubicin (Ellence)/docetaxel (Taxotere), orGEDoc, with prophylactic filgrastim (Neupogen), as primary systemictherapy in 77 evaluable patients with primary breast cancer are reportedherein. Dose-limiting toxicities were grade 3 febrile neutropenia(n = 1) and grade 3 diarrhea (n = 2) at the fourth dose level ofGEDoc tested (gemcitabine at 800 mg/m2 days 1 and 8, epirubicin at90 mg/ m2 day 1, and docetaxel at 75 mg/m2 day 1). As assessed byultrasound, 92% of patients responded overall (22% complete response),and 79% of patients could undergo breast-conserving surgery. Thepathologic complete response rate in resected breast tissue was 26%.

Progress With a Purpose: Eliminating Suffering and Death Due to Cancercancer is the second leading cause of death in the United States, with more than 500,000 men, women, and children succumbing to the disease each year. The idea, then, that we can eliminate the suffering and death due to cancer in the United States by the year 2015 may appear impractical, if not irrational and impossible. It seems inconceivable that in the first part of the 21st century every patient could survive cancer. Doubt can be attributed to awareness of the biologic complexity of cancer and seeing the pace of clinical progress through the prism of the 20th century.

Risk Models for Chemotherapy-Induced Neutropenia in Non-Hodgkin’s LymphomaNon-Hodgkin’s lymphoma is primarily a disease of the elderly, with61% of the new cases reported in patients 60 years old or older. Aggressivecombination chemotherapy can cure some patients, but there arefrequently treatment failures and overall survival is low. Retrospectivestudies have found that treatment with less than standard chemotherapydoses is associated with lower survival, and surveys of practice patternshave found that many patients, especially elderly ones, are treated withsubstandard regimens and doses. Neutropenia is the major dose-limitingtoxicity of chemotherapy in patients with non-Hodgkin’s lymphoma.First-cycle use of colony-stimulating factor (CSF) can reduce the incidenceof neutropenia and its complications and help maintain the chemotherapydoses. Researchers have investigated risk factors in patientswith non-Hodgkin’s lymphoma to determine which patients are at highestrisk for neutropenia and would benefit from targeted first-cycle CSFsupport. It has been shown in several studies that advanced age, poorperformance status, and high chemotherapy dose intensity are risk factors.Other trials suggest that low serum albumin levels, elevated lactatedehydrogenase levels, bone marrow involvement, and high levelsof soluble tumor necrosis factor receptor are also risk factors. Doseintensity has also been shown in many studies to be an important predictorof survival in patients with non-Hodgkin’s lymphoma. Managingthe toxicity of chemotherapy with CSF has facilitated the deliveryof planned dose on time, as well as dose-intensified chemotherapy regimens.The promising results from recent clinical trials of dose-denseregimens with CSF support suggest that this could prove to be the beststrategy for improving patient outcomes.

Current Management of Depression in Cancer PatientsIn their paper, Schwartz and colleagues review the risk factors for depression and suicide in patients with cancer and argue convincingly that screening for depression can be simply and quickly performed. They also delineate the efficacy and potential adverse effects of psychotherapeutic or psychopharmacologic treatments for these patients. Buttressing the identification and treatment of depression in the cancer patient are vital, ongoing scientific developments that flow from an increased understanding of interactions among the brain, endocrine system, and immune system. This rapidly evolving body of neurobiological knowledge has catalyzed fundamental changes in how we conceptualize depression in cancer patients and has important ramifications regarding the treatment and prevention of depressive syndromes in this setting.

gSevere, debilitating fatigue is common in cancer patients. For many,it is the symptom that interferes most with normal routines. Virtuallyevery modality used to treat cancer may cause fatigue, as can complicationsof the disease such as sleep disturbances, infections, malnutrition,hypothyroidism, and anemia. There is a significant overlap betweendepression and fatigue in many patients. Given the high prevalenceof cancer-related fatigue, frequent assessment of patients is essential.The evaluation should include an attempt to identify reversiblecauses of fatigue, and screening for depression. However, many cancerpatients suffer from fatigue even in the absence of any identifiable,reversible cause. For these patients, consideration can be given to suitableexercise programs, educational support and counseling, and energyconservation strategies. A trial of a stimulant medication is alsoreasonable. Given the heterogeneity of patients, individualized approachesare needed. For anemic patients undergoing chemotherapy,erythropoietic agents can increase hemoglobin levels. The impact ofthese drugs on fatigue and quality of life is uncertain. Recent reports ofincreased mortality and thrombotic events in cancer patients treatedwith epoetin require further investigation.
