Commentary (Cohen/Khuri): Treatment of Non–Small-Cell Lung Cancer in Older Persons
January 1st 2003The importance of cancer as aproblem in the elderly is gainingincreasing appreciationdue, in part, to the demographicchanges taking place in this countryand around the world and their associationto the incidence of cancer.Ongoing epidemiologic research overthe past several decades has consistentlyconfirmed the continuing trendtoward an aging population. In theUnited States, an anticipated 20.1%of the population will be 65 years ofage or older by 2030, the number ofpeople 75 years of age or older willhave tripled, and the 85-or-older agegroup will have doubled.[1]
Treatment of Non–Small-Cell Lung Cancer in Older Persons
January 1st 2003The majority of individuals diagnosed with lung cancer in theUnited States are 70 years of age and older. Defining appropriatetherapy for older patients with non–small-cell lung cancer (NSCLC) isbecoming a major focus of clinical research. In this article, we reviewthe available data on clinical predictors of risk and benefit for elderlyNSCLC patients receiving treatment via a variety of modalities, includingsurgery, radiotherapy, combined radiotherapy and chemotherapy,and chemotherapy alone. The data demonstrate that subgroups ofelderly patients benefit from appropriately selected treatment. Participationof older patients in clinical trials designed to assess efficacy,toxicity, and quality-of-life outcomes for recently developed treatmentmodalities in this population is critical.
Commentary (Meissner): Diagnosis of Venous Thromboembolic Disease in Cancer Patients
January 1st 2003The diagnosis of venous thromboembolismon the basis ofclinical signs and symptoms isnotoriously inaccurate and, therefore,mandates confirmatory diagnostictesting. Unfortunately, all diagnostictests for deep venous thrombosis(DVT) and pulmonary embolismhave clinical or practical limitations.Contrast venography and pulmonaryarteriography are usually regarded asthe reference standards for the diagnosisof DVT and pulmonary embolism,respectively. However, evencontrast venography may be impossibleto perform in 9% to 14% ofpatients, may fail to visualize 10% to30% of venous segments, and maybe associated with postvenographythrombosis in up to 8% of patients.[1]
Commentary (Hemstreet): Management of Sexual Dysfunction After Prostate Brachytherapy
January 1st 2003Over the past decade, prostatebrachytherapy has been usedincreasingly as definitivetreatment for early-stage carcinomaof the prostate gland, with the majorityof the literature on brachytherapyreporting biochemical results as favorableas those in the most positiveradical prostatectomy and externalbeamradiation therapy series.[1-4]Because of a lack of definitive evidencesupporting the efficacy of onelocal treatment approach over another,quality-of-life (QOL) parametershave assumed greater importance. Ithas been widely asserted that preservationof potency is more likely followingbrachytherapy, but longerfollow-up has raised substantialdoubts about brachytherapy’s potency-sparing advantage.[5,6] In addition,brachytherapy results in amyriad of previously unrecognizedeffects on sexual function.[7,8]
Commentary (Boxer): Management of Sexual Dysfunction After Prostate Brachytherapy
January 1st 2003The current ONCOLOGY articleby Drs. Merrick, Wallner,and Butler is a valuable additionto the literature. An estimated189,000 American men were diagnosedwith prostate cancer in 2002,and 30,200 died of the disease, makingit the most common cancer amongmen, and the second most commoncause of cancer death.[1] The treatmentshave led to a high rate of cure,but the results of treatment oftencause a reduction in quality of life.
Commentary (Lohr): Diagnosis of Venous Thromboembolic Disease in Cancer Patients
January 1st 2003This article nicely describes concernsabout the underdiagnosisof deep vein thrombosis(DVT) and superficial vein thrombosisin patients with malignancy. Theincidence of these conditions in thissetting has been demonstrated to beas high as 51% in postmortem studies,as opposed to the clinically recognized15% rate. The articlereinforces the need for better diagnostictools than are currently availablein clinical practice. It alsostresses the need for a high clinicalsuspicion. Duplex ultrasound shouldbe used as a first step, and othermodalities listed in the article needto be used when appropriate.
Nonmyeloablative Preparative Regimens for Allogeneic Hematopoietic Transplantation
High-dose myeloablative therapy with allogeneic hematopoietictransplantation is an effective treatment for hematologic malignancies,but this approach is associated with a high risk of complications.The use of relatively nontoxic, nonmyeloablative, or reduced-intensitypreparative regimens still allows engraftment and the generation ofgraft-vs-malignancy effects, is potentially curative for susceptiblemalignancies, and reduces the risk of treatment-related morbidity.Two general strategies along these lines have emerged, based on theuse of (1) immunosuppressive chemotherapeutic drugs, usually apurine analog in combination with an alkylating agent, and (2) lowdosetotal body irradiation, alone or in combination with fludarabine(Fludara).
Nursing Shortage to Worsen Over Next 2 Decades

Cancer Risk From Tainted Polio Vaccine Undetermined: IOM Report
December 1st 2002WASHINGTON-There is insufficient evidence to prove or disprove whether polio vaccine doses contaminated with simian virus-40 (SV40) between 1955 and 1963 can trigger certain cancers in humans, according to a report by the Institute of Medicine (IOM), a part of the National Academy of Sciences. Although most population studies have not found an increase in the cancers among people inoculated with the vaccine between 1955 and 1963, a possible link cannot be completely ruled out because of substantial statistical and design limitations in the 13 studies, an IOM committee concluded.
Tailored Messages Motivate Women to Get Mammograms
December 1st 2002WASHINGTON-In motivating women to get timely mammograms, discussions tailored to individuals’ particular reasons for not getting mammograms are far more effective than general recommendations, said Diane Ruth Lauver, PhD, RN, professor of women’s health, University of Wisconsin, Madison. Speaking at the American Psychological Association Conference on Enhancing Outcomes in Women’s Health, she reported on a study of motivational messages given to 797 Midwestern women, age 51 to 80, who had not had a mammogram in the past 13 months.

Fludarabine Combos Showing Efficacy in Lymphomas
December 1st 2002LUGANO, Switzerland-For low-grade lymphomas, fludarabine (Fludara)-based combination therapy may have greater efficacy than single-agent flu-darabine, especially when a monoclonal antibody is part of the combination, a series of recent European investigations suggest. The investigations, presented at the Eighth International Conference on Malignant Lymphoma (ICML), show that various combination therapies hold promise, although a lack of coordination among non-US study groups has hampered progress somewhat.

New Tyrosine Kinase Inhibitor More Potent Than STI-571
December 1st 2002MIAMI BEACH -The Bcr-Abl tyrosine kinase inhibitorPD173955 (PD17) binds to the targetATP binding pocket even moreefficiently than STI-571 (imatinibmesylate, Gleevec).
