Novel Concepts in Radioimmunotherapy for Non-Hodgkin's LymphomaTositumomab/iodine-131 tositumomab (Bexxar) and ibritumomab tiuxetan (Zevalin) are radioimmunoconjugates targeting the CD20 antigen. Both agents are approved in the United States for use in relapsed or refractory, indolent or transformed, B-cell lymphoma. These agents are well tolerated and have the highest levels of single-agent activity observed in these histologies. This review will summarize the key trials that led to approval of both I-131 tositumomab and ibritumomab tiuxetan, and then focus on four novel therapeutic concepts in radioimmunotherapy: retreatment, therapy of de novo indolent lymphoma, therapy of aggressive histologies, and incorporation in high-dose therapy programs utilizing autologous stem cell support.

Commentary (Gruber et al)-What the Physician Needs to Know About Lynch Syndrome: An UpdateIn many respects, Lynch syndromeserves as the paradigm of cancergenetic syndromes. It is relativelycommon and accounts for approximately3% to 5% of colorectal cancer cases.The genetic basis is clearly understood,and genetic testing is clinically availableand routinely incorporated intoclinical practice. Furthermore, the diagnosishas a profound impact on themanagement of individuals at risk, andinterventions have been shown tosubstantially reduce morbidity andmortality. These advances in our understandingare attributable, in largepart, to the seminal work of Dr. HenryLynch and his colleagues.[1-3]

Myalgias and Arthralgias Associated With PaclitaxelPaclitaxel-induced myalgias and arthralgias occur in a significantfraction of patients receiving therapy with this taxane, potentiallyimpairing physical function and quality of life. Paclitaxel-inducedmyalgias and arthralgias are related to individual doses; associationswith the cumulative dose and infusion duration are less clear. Identificationof risk factors for myalgias and arthralgias could distinguisha group of patients at greater risk, leading to minimization of myalgiasand arthralgias through the use of preventive therapies. Optimalpharmacologic treatment and possibilities for the prevention of myalgiasand arthralgias associated with paclitaxel are unclear, partially dueto the small number of patients treated with any one medication. Theeffectiveness of nonsteroidal anti-inflammatory drugs (NSAIDs) is themost frequently documented pharmacologic intervention, although noclear choice exists for patients who fail to respond to NSAIDs. However,the increasing use of weekly paclitaxel could necessitate daily administrationof NSAIDs for myalgias and arthralgias and leave patients at riskfor adverse effects. This concern may also limit the use of corticosteroidsfor the prevention and treatment of paclitaxel-induced myalgias andarthralgias. Data from case reports suggest that gabapentin (Neurontin),glutamine, and, potentially, antihistamines (eg, fexofenadine [Allegra])could be used to treat and/or prevent myalgias and arthralgias. Giventhe safety profile of these medications, considerable enthusiasm existsfor evaluating their effectiveness in the prevention and treatment ofpaclitaxel myalgias and arthralgias, particularly in the setting ofweekly paclitaxel administration.

Quality-of-Life End Points in Oncology Drug TrialsHealth-related quality of life (HRQL) is a multidimensional construct that represents the patient’s perspective on valued aspects of health and functioning. Over the last several years, the pharmaceutical industry, as well as health care providers and the patient advocacy community, have shown increasing interest in HRQL as an outcome measure. Pharmaceutical companies and other sponsors of cancer clinical trials are seeking novel approaches with which to establish the benefits of treatment and to differentiate their products from other marketed products. Health care providers hope to provide cancer patients with therapies that positively affect their quality of life. To date, however, most oncology drug approvals have been based on traditional end points, such as survival and tumor response rate. This article will focus on some of the lessons learned from recent reviews of HRQL data and will describe some of the many challenges that lie ahead. ONCOLOGY 13(10):1439-1442, 1999]

Commentary (Brandes/Brahmer): Perspectives on Salvage Therapy for Non–Small-Cell Lung CancerAbout 172,570 new cases ofnon–small-cell lung cancer(NSCLC) are expected to bediagnosed in 2005 in the United States,and almost as many will die of thedisease. Patients with effusions or metastaticdisease are candidates for combinationchemotherapy. The regimensof choice are platinum-based combinationchemotherapy schedules. Giventhat most patients will experience diseaseprogression despite their initialtreatment, they may be eligible for second-line chemotherapy, provided theyhave an acceptable performance status.

Current Controversies in the Management of Hodgkin's LymphomaDespite significant improvements in the treatment of Hodgkin's lymphoma over the past 2 decades, physicians continue to face dilemmas in therapy for the disease, and many cured patients live with complications of treatment. Newer therapeutic options are still needed for the disease, to minimize complications and to improve the treatment of patients in relapse. This review considers the treatment of Hodgkin's lymphoma in younger patients, addressing such issues as which patients with early-stage disease may require radiotherapy, what prognostic factors provide information that can affect treatment choices in patients with advanced disease, and what we have learned about treatment complications in this setting.

Renal-Cell CarcinomaRenal-cell carcinoma (RCC) is curable only in patients presenting with resectable, early-stage disease. Advanced local or metastatic disease carries an approximate 15% 5-year survival rate. However, the natural history of metastatic RCC is heterogeneous, and aggressive palliative treatment is recommended, especially for patients with a solitary metastatic site and good performance status.

Pancreatic Cancer: Incremental Success in Overcoming a Major Therapeutic ChallengeErlotinib (Tarceva) is a human epidermal growth factor receptor type 1/epidermal growth factor receptor (HER1/EGFR) tyrosine kinase inhibitor initially approved by the US Food and Drug Administration for the treatment of patients with locally advanced or metastatic non–small-cell lung cancer after failure of at least one prior chemotherapy regimen. In this report, we present the pivotal study that led to the approval of erlotinib in combination with gemcitabine (Gemzar) in patients with locally advanced/metastatic chemonaive pancreatic cancer patients. The combination demonstrated a statistically significant increase in overall survival accompanied by an increase in toxicity. Physicians and patients now have a new option for the treatment of locally advanced/metastatic adenocarcinoma of the pancreas.

IP Therapy in Front-Line Care for Advanced Ovarian CancerIntraperitoneal (IP) chemotherapy is a preferred treatment option that should be offered to all women for front-line treatment of stage III optimally debulked ovarian cancer. Patients should be provided with information on the survival and toxicity for both IP and intravenous (IV) therapies, as well as practical information about the administration of each regimen, so that they may play an active role in the decision-making process. When making a decision between IP and IV therapeutic options, the experience and preference of the oncologist are critical factors in determining appropriate therapy for each woman.
