Further Considerations About NHL in the Elderly

As noted in part 1 of this two-part article, non-Hodgkin's lymphoma is one of a few malignancies that have been increasing in incidence over the past several decades. Likewise, these disorders are more common in elderly patients, with a median age of occurrence of 65 years. Therapy in elderly patients may be affected by multiple factors, especially attendent comorbidities. The approaches to management of these patients, with either indolent or aggressive disease processes, have been based on prospective clinical trial results, many of which have included a younger patient population. Fortunately over the past decade, results of treatment trials that have targeted an older patient population have emerged. The disease incidence and treatment approaches for both follicular (part 1) and diffuse aggressive (part 2) histologies in elderly patients are reviewed, as well as the impact of aging on the care of these patients.

DNA Ploidy and Cell Cycle Analysis in Cancer Diagnosis and Prognosis

The article by Dr. Ross provides an overview of the current status of the medical literature regarding the role of DNA ploidy and cell cycle analysis in cancer diagnosis and patient prognosis. The scope of the article is quite broad, covering virtually every organ system and, as such, provides only a brief summary of the data in each diagnostic category. From these data, there is general agreement about the value of detection of aneuploidy in tumor specimens but a lack of consensus about the importance of cell proliferation analyses, such as S-phase fraction (SPF) measurements. This conclusion reflects the inherent variability in the two determinations. Detection of aneuploidy by analytic cytometry is reliable; it is accurate and depends upon the specimen (frozen vs formaldehyde- fixed, presence of necrosis, cellularity) as well as the quality of specimen preparation. Thus, DNA ploidy analysis can easily be standardized, minimizing intralaboratory variation. Cell cycle analysis, however, is more complex and as yet is not standardized.

Concurrent RT With 5-FU/Epirubicin and Cisplatin or Irinotecan for Locally Advanced Upper GI Adenocarcinoma

From the results of recent studies, it is likely that multimodality therapy with chemotherapy and radiation treatment may improve the overall outcome of locally advanced upper gastrointestinal (GI) malignancies, including esophageal, gastric, pancreatic, and biliary tract carcinomas. However, more effective, more optimal, and less toxic chemotherapy regimen(s) with concomitant radiotherapy are needed beyond the concurrent continuous-infusion fluorouracil (5-FU) with radiation that is commonly applied in general practice. Epirubicin (Ellence), cisplatin, and irinotecan (Camptosar) are all active cytotoxic chemotherapy agents in upper GI cancers. Two phase I studies were designed to test the tolerability of the combination of radiotherapy with infusional 5-FU, epirubicin, and cisplatin (ECF) or 5-FU, irinotecan, and epirubicin (EIF) in the treatment of locally advanced upper GI malignancies.

Management of Comorbid Diabetes and Cancer

Diabetes mellitus is a frequent comorbidity of cancer patients. The growing epidemic of diabetes is anticipated to have tremendous impact on health care. Diabetes may negatively impact both cancer risk and outcomes of treatment. Oncology nurses are ideally positioned to identify patients at risk for complications that arise from cancer treatment in the setting of pre-existing diabetes. Additionally, oncology nurses may be the first to identify underlying hyperglycemia/hidden diabetes in a patient undergoing cancer treatment. Strategies for assessment and treatment will be discussed, along with specific strategies for managing hyperglycemia, potential renal toxicity, and peripheral neuropathy. Guidelines for aggressive treatment of hyperglycemia to minimize risks of complications will be reviewed. The role of interdisciplinary care, utilizing current evidence, is crucial to supporting patients and their families as they manage the challenges of facing two life-limiting diseases. Whole-person assessment and individualized treatment plans are key to maximizing quality of life for patients with cancer and diabetes.

Molecular Targets on Blood Vessels for Cancer Therapies in Clinical Trials

This review covers progress to date in the identification of molecular targets on blood vessels in cancers, as well as agents that act on those targets, with emphasis on those currently in clinical trials. Current vascular-targeting therapies comprise two general types—antiangiogenic therapy and antivascular therapy. Advances in antiangiogenic therapies, particularly inhibitors of vascular endothelial growth factors and their receptors, have clarified the capacity of these inhibitors to change tumor-associated vessel structure to a more normal state, thereby improving the ability of chemotherapeutics to access the tumors. The responses of other antiangiogenesis target molecules in humans are more complicated; for example, αvβ3 integrins are known to stimulate as well as inhibit angiogenesis, and cleavage of various extracellular proteins/proteoglycans by matrix metalloproteinases produces potent regulators of the angiogenic process. Antivascular therapies disrupt established blood vessels in solid tumors and often involve the use of ligand-based or small-molecule agents. Ligand-based agents, irrespective of the antiangiogenic capacity of the ligand, target antivascular effectors to molecules expressed specifically on blood vessels, such as aminopeptidase N, fibronectin extra-domain B, and prostate-specific membrane antigen. Small-molecule antivascular agents, which are not targeted to molecules on blood vessels, rely on physical differences between the vasculatures in tumors and those in normal tissues.

Dendritic Cell Function in Sentinel Nodes

Intraoperative lymphatic mapping and sentinel lymphadenectomy has become an increasingly popular technique for staging the regional lymph nodes in early-stage melanoma. This operative technique allows for detailed pathologic analysis of the first (or sentinel) lymph node in direct connection with the primary tumor, and provides a unique opportunity for assessing potential immunologic interactions between the primary tumor and regional lymph node basin. We performed lymphatic mapping and sentinel lymphadenectomy on 25 patients with early-stage melanoma and resected an additional nonsentinel node in each case. Sentinel and nonsentinel nodes were evaluated by routine pathologic analysis. A portion of each node was processed for expression of the dendritic markers of activation CD80, CD86, and CD40, and their corresponding T-cell receptors CTLA-4 and CD28. Of 25 patients undergoing lymphatic mapping and sentinel lymphadenectomy, 20 (80%) had matched sentinel and nonsentinel nodes. A total of 26 matched lymph node sets were obtained: three pairs from one patient and two from an additional two patients. Reverse transcription polymerase chain reaction analyses of corresponding sections of the sentinel and nonsentinel nodes demonstrated a marked reduction in semiquantitative expression of CD80 (77%), CD86 (77%), and CD40 (85%), as well as CTLA-4 (88%) and CD28 (85%) in sentinel as compared to nonsentinel nodes. The diminished expression of the dendritic cell markers appeared to be unrelated to the B-cell (CD20) and T-cell (CD2) expression. Lymphatic mapping and sentinel lymphadenectomy allows for detailed pathologic and molecular characterization of sentinel nodes. Our results suggest a quantitative reduction in dendritic cell markers in sentinel as compared to nonsentinel nodes, which may be important in the immunologic interaction between the primary site and regional lymph node basin and may also serve as useful criteria for identifying sentinel nodes.

Clinical Trials in Ovarian Cancer, Part 2

The American Cancer Society has estimated that 23,300 women will develop ovarian cancer in 2002, and 13,900 women will die from the disease.[1] The 5-year survival rate is about 80% for women with stage I disease, 50% for women with stage II disease, 25% for women with stage III disease, and 15% for women with stage IV disease. Among women with advanced-stage disease, optimal debulking surgery, as well as platinum/taxane-based adjuvant therapy prolongs disease-free and median survival.[2,3] Population-based data suggest that guidelines for therapy are not uniformly followed in community practice.[4] In addition, older patients appear to receive less aggressive treatment than younger patients.

Honing Therapy for Rectal Cancer

Epidermal growth factor receptor (EGFR) and vascular endothelial growth factor (VEGF) are often overexpressed in colorectal cancer and are associated with inferior outcomes. Based on successful randomized phase III trials, anti-EGFR and anti-VEGF therapeutics have entered clinical practice. Cetuximab (Erbitux), an EGFR-specific antibody, is currently approved in the United States in combination with irinotecan (Camptosar) for patients with metastatic colorectal cancer refractory to irinotecan or as a single agent for patients unable to tolerate irinotecan-based therapy. In retrospective analyses, patients with EGFR-expressing rectal cancer undergoing neoadjuvant radiation therapy had a significantly inferior disease-free survival and lower rates of achieving pathologic complete response. Based on the positive data in metastatic colorectal cancer and synergy with radiation therapy seen in preclinical models, there is a strong rationale to combine cetuximab with neoadjuvant radiation therapy and chemotherapy in rectal cancer. Bevacizumab (Avastin), a VEGF-specific antibody, was the first antiangiogenic agent to be approved in the United States for use in combination with standard chemotherapy in the first- and second-line of treatment in metastatic colorectal cancer. VEGF-targeted therapy may lead to indirect killing of cancer cells by damaging tumor blood vessels, and may increase the radiosensitivity of tumor-associated endothelial cells. VEGF blockade can also "normalize" tumor vasculature, thereby leading to greater tumor oxygenation and drug penetration. This review will address completed and ongoing trials that have established and continue to clarify the effects of these agents in rectal cancer.

Induction Chemotherapy for Resectable Non–Small-Cell Lung Cancer

Lung cancer remains the leading cause of cancer death in Americanmen and women. Non–small-cell lung cancer (NSCLC) accountsfor 85% of these cases. Although surgery is the best curative approachfor resectable NSCLC, long-term survival for patients with operabledisease remains poor. More than half of patients who initially presentwith stage I to IIIA disease experience relapse of metastatic disease.Postoperative adjuvant therapy has been evaluated in several randomizedtrials, and provides a survival benefit. It appears reasonable tolook to induction chemotherapy, or preoperative chemotherapy, to providea similar improvement in survival with early treatment ofmicrometastatic disease. Multiple trials of induction therapy have beencarried out with encouraging results. The use of various induction regimenswith chemotherapy alone or chemotherapy combined with radiotherapyfor stage IIIA NSCLC is under investigation. Randomized trialsare under way to better define the role of induction therapy in themultimodality treatment of NSCLC.
