Management of Colorectal Cancer in Older PatientsAn increasing body of evidence suggests that geriatric patients can benefit from and tolerate standard chemotherapy similarly to younger patients in the settings of both early- and advanced-stage colorectal cancer. Assessment of this unique population requires more comprehensive evaluation in addition to routine history, physical examination, and laboratory tests. Specific considerations of their physiologic functional changes will help physicians better manage these patients. Ongoing studies are now designed to better understand the decision-making process, safety profile, and efficacy of various treatment regimens in geriatric patients.

Adjuvant Therapy for Colorectal Cancer: Increasingly Complex as Patients AgeThe treatment of older patients with colorectal cancer is not always straightforward. As highlighted in the article by Dr. Ades, the heterogeneity of physiologic aging, the increasing prevalence of comorbid disease with age, and changing preferences with aging make counseling about adjuvant therapy more complex for older patients than for younger patients.

Commentary (Kelly/Goldberg): CEA Monitoring in Colorectal CancerCarcinoembryonic antigen (CEA) monitoring in patients with stage I-IV colorectal cancer has been, and remains, a controversial issue in oncology practice. Recommendations vary from bimonthly monitoring to no monitoring in the surveillance setting (for stage I-III disease). In the metastatic setting, there are no clear guidelines for CEA follow-up, although continued monitoring in such patients is common in the oncology community. This manuscript reviews the accuracy of CEA testing, its value as a prognostic indicator, and its role in surveillance and response assessment. The limitations of the test in the adjuvant and metastatic settings are illustrated through several case reports from the Colorectal Oncology Clinic at Roswell Park Cancer Institute. Guidelines for CEA monitoring are provided, based on a detailed literature review and institutional experience.

Recognizing and Managing Side Effects Associated With Novel Targeted Therapies:Nursing management of patients with advanced malignancies presents a formidable challenge. In addition to the discomfort and debilitation these diseases can cause, side effects of traditional treatment modalities such as surgery, chemotherapy, and radiation may lead to severe and sometimes fatal sequelae. New targeted therapies promise an effective treatment with more easily tolerated and managed side effects. Basic understanding of the drugs' mechanism of action contributes to the successful management of the toxicities that can be manifested. Effective patient education results in improved compliance with treatment regimens and potentially improved clinical outcomes. Nursing intervention remains a vital component in the successful use of these novel agents.

Genetic Counseling in Hereditary Nonpolyposis Colorectal CancerRecent identification of gene mutations responsible for hereditary nonpolyposis colorectal cancer (HNPCC) has made possible the presymptomatic diagnosis of at-risk family members. If DNA testing shows that a family member is a gene carrier, that individual's lifetime cancer risk is approximately 90%. If the test is negative, the family member's cancer risk drops to that of the general population.

Pemetrexed in Transitional Cell Carcinoma of the UrotheliumCurrently, the four-drug combination of methotrexate, vinblastine,doxorubicin (Adriamycin), and cisplatin (MVAC) or the two-drug combinationof gemcitabine and cisplatin (GC) represents the standard ofcare for patients with locally advanced and metastatic transitional cellcarcinoma of the urothelium. Recently, there has been a plethora ofdata from other chemotherapeutic regimens. Promising new agents,such as the multitargeted antifolate pemetrexed (Alimta), and new drugcombinations have demonstrated increased efficacy and/or decreasedtoxicity compared with current regimens. Currently, data are availablefrom three phase II studies utilizing pemetrexed or the combination ofpemetrexed/gemcitabine (Gemzar) in patients with locally advanced andmetastatic transitional cell carcinoma of the urothelium. Further investigationof combinations of pemetrexed and other active drugs inthe treatment of patients with locally advanced and metastatic diseaseis warranted.
