Therapeutic Options in Gastric Cancer: Neoadjuvant Chemotherapy vs Postoperative ChemoradiotherapyThe majority of patients who undergo resection for gastric cancer experience relapse and ultimately die of their disease. Therefore, considerable attention has been paid to neoadjuvant and adjuvant strategies to improve surgical outcomes. Two different approaches have been tested in major clinical trials conducted in the past several years: Postoperative chemoradiotherapy was assessed in a US Southwest Oncology Group/Intergroup study (SWOG 9008/INT 0116), and perioperative chemotherapy was studied in a UK Medical Research Council (MRC) randomized trial (the MRC Adjuvant Gastric Infusional Chemotherapy [MAGIC] trial). These trials demonstrated statistically significant survival benefits in patients with resectable gastric cancer. This review will consider these trials and their implications for clinical practice.

Gynecologic Malignancies in Older WomenThe demographics of the US population continue to change dramatically, as the absolute number and proportion of older people relative to the remainder of the population increases. Last year, the number of persons older than 65 years was estimated to be 35 million, representing almost 13% of the overall population; by 2030, the older population is expected to double. Along with the general aging of the population, the percentage of persons older than 85 years is also growing rapidly, as is the ethnic and racial diversity within the older population.

Combined-Modality Therapy for Head and Neck CancerIn the past, head and neck cancers were felt to be primarily a locoregional control challenge. Distant metastases were not thought to occur frequently. However, the popularity of combined-modality programs emphasizing regional treatment with surgery and radiation in the 1960s enhanced the ability to control the disease at the primary site and within the regional cervical lymphatics. Nevertheless, survival was not improved because treatment failure at distant sites occurred frequently. Apparently, prior treatment programs that did not provide locoregional control masked the ability of this disease to spread to distant sites. Patients died of uncontrolled locoregional disease before they could experience distant metastases.

Management of Anemia in Patients With CancerSince our first "Quality of Life in Current Oncology Practice and Research" symposium was held at St. Mary Medical Center in Long Beach, California in February 1989, and published in ONCOLOGY in May 1990, there has been a marked increase in the use of quality of life measures to determine the outcomes of interventions in clinical oncology. Measuring the effects of anemia treatment with quality of life tools is a fine example of the importance of these tools to gauge the impact and clinical significance of interventions. It is, therefore, both timely and relevant that we dedicate our fifth symposium to the management of anemia in patients with cancer.

The Prostate Cancer Intervention Versus Observation Trial (PIVOT)The Prostate Cancer Intervention Versus Observation Trial (PIVOT) should prove interesting in that the study design will permit observation of the natural history of a potentially lethal malignant disease, influenced only by palliative treatments. My comments will focus on the concerns raised by this study design. I will not address possible biases of the trial introduced by: (1) enrollment of less than 20% of the eligible population; (2) an enrollment rate per participating center of less than 3 patients per year; (3) a 7-year enrollment period; and (4) a 12-year follow-up (for a total trial duration of 19 years).

Active Surveillance: Not Your Father’s Watchful WaitingActive surveillance is becoming a very reasonable and appropriate “treatment” strategy for men with low-risk localized prostate cancer, as Large and Eggener eloquently describe in this review article. It is important to recognize that active surveillance is not what was once referred to as “watchful waiting,” which I believe many patients interpret as “watching and waiting to die.

Paclitaxel for Breast Cancer: The Memorial Sloan-Kettering Cancer Center ExperienceThe proven safety profile and antitumor activity of paclitaxel (Taxol) in the treatment of metastatic breast cancer led investigators at Memorial Sloan-Kettering Cancer Center (MSKCC) to further examine the agent's potential in the treatment of advanced breast cancer. Efficacy and tolerability studies of paclitaxel as single-agent therapy were undertaken, along with parallel investigations of quality-of-life parameters. The studies examined the effects of 96-hour infusion schedules of paclitaxel and are currently assessing the feasibility of a weekly 1-hour infusion schedule. Researchers at MSKCC also compared the results of a variety of two- and three-drug paclitaxel-containing regimens to determine possible synergism and better define safety profiles. They examined the combination of paclitaxel and edatrexate, as well as a promising combination of paclitaxel and a monoclonal antibody directed at growth factor receptors. The latter ongoing trial will include both laboratory studies that examine possible cellular mechanisms for the combination's observed synergy and a clinical trial that combines paclitaxel with a monoclonal antibody directed against the epidermal growth factor. In conclusion, the investigators discuss the optimal integration of paclitaxel into doxorubicin/cyclophosphamide (Cytoxan, Neosar)-based adjuvant therapy for node-positive stage II-III resectable breast cancer.

What Is the Role of Maintenance Rituximab in Follicular NHL?Recent trials have demonstrated improvements in progression-free and overall survival with the inclusion of the chimeric anti-CD20 monoclonal antibody rituximab (Rituxan) in chemotherapy regimens for treatment-naive and relapsed patients with advanced-stage follicular non-Hodgkin's lymphoma (NHL). As rituximab therapy has significant single-agent activity in follicular NHL, is generally well tolerated, and has no dose-limiting or significant hematologic toxicity, a number of approaches evaluating maintenance therapy with extended dosing of rituximab are being tested. Trials have demonstrated prolonged progression-free survival in patients treated with maintenance rituximab using a variety of schedules following treatment with single-agent rituximab, induction or salvage chemotherapy, or salvage therapy with rituximab and chemotherapy combinations. Small increases in neutropenia and infections have been reported with extended rituximab use. Ongoing trials are evaluating the optimal use of rituximab (maintenance vs retreatment) and the benefit of rituximab maintenance following treatment of therapy-naive patients treated with rituximab-containing chemoimmunotherapy induction regimens. This article discusses the risks and benefits of maintenance rituximab for follicular NHL.

Gynecologic Manifestations of Hereditary Nonpolyposis Colorectal CancerHereditary nonpolyposis colorectal cancer (HNPCC) is an autosomaldominant cancer susceptibility syndrome associated with inheriteddefects in the DNA mismatch repair system. HNPCC family membersare at high risk for developing colorectal, endometrial, and ovariancancers. Studies of HNPCC families have helped define the importantrole that mismatch repair genes play in the molecular pathogenesis ofendometrial and ovarian cancers. This review will describe some of theimportant clinical and molecular features of HNPCC-related endometrialand ovarian cancer and describe how genetic susceptibility can beidentified in patients with sporadic endometrial and ovarian cancers. Itis important to identify patients with HNPCC, as families of mutationcarriers may benefit from genetic counseling, testing, and intensifiedcancer surveillance.

The Role of Intravenous Iron in Cancer-Related AnemiaPatients with cancer may have an absolute or functional iron deficiency as a result of their disease or its treatment. These conditions can lead to an insufficient supply of iron for incorporation into erythrocytes during supportive care with erythropoiesis-stimulating proteins for chemotherapy. The use of supplemental iron therapy is well established in patients with chronic kidney disease and anemia, but less well studied in the oncology/hematology setting. Furthermore, the use of oral iron formulations in patients with cancer and anemia is limited by poor absorption in the duodenum, arduous dosing requirements (three times a day), and a high likelihood of gastrointestinal side effects. Two recent studies have shown that intravenous (IV) iron (iron dextran or ferric gluconate) increases the hematopoietic response rates in cancer patients who were receiving chemotherapy and treated with epoetin alfa (Procrit) for anemia. The effects on hemoglobin levels and measures of iron metabolism were notably greater with IV iron formulations than with oral iron formulations. The results from several ongoing trials of IV iron in patients treated with epoetin alfa or darbepoetin alfa (Aranesp) for chemotherapy-induced anemia should lead to a greater understanding of the role of IV iron supplementation in improving the hematopoietic responses in these patients.

Commentary (Chung/Johnson): Targeting the Epidermal Growth Factor ReceptorThe epidermal growth factor receptor (EGFR) promotes the growth of different cell types and has been implicated in tumorigenesis. The EGFR comprises a family of four structurally similar tyrosine kinases with a complex link to downstream signaling molecules that ultimately regulate key cell processes. Anti-EGFR agents have been developed as promising therapeutic anticancer targets, and some have been recently approved for the treatment of non-small-cell lung cancer and colon cancer. The two anti-EGFR therapies with the greatest clinical application are monoclonal antibodies that block the binding of ligands to EGFR and small-molecule tyrosine kinase inhibitors that inhibit the binding of adenosine triphosphate to the internal tyrosine kinase receptor of EGFR. We attempt to give an overview of the EGFR function and biology, focusing on the most important clinical findings and applications of EGFR inhibitors in lung and head and neck cancer.

Endoscopic Ultrasound Fine-Needle Aspiration in the Staging of Non‑Small‑Cell Lung CancerPrecise mediastinal staging of non-small-cell lung cancer is extremely important, as mediastinal lymph node metastases generally indicate unresectable disease. Reliance on computed tomography (CT) and positron-emission tomography (PET) alone to stage and determine resectability is limited by false-positive results. Whenever possible, pathologic confirmation of metastases is desirable. Mediastinoscopy and transbronchial fine-needle aspiration are widely established but imperfect modalities. Endoscopic ultrasound fine-needle aspiration (EUS-FNA) has emerged as a diagnostic and staging tool because of its safety, accuracy, and patient convenience. We reviewed 13 prospective studies evaluating the comparative performance of EUS for staging lung cancer. We conclude that EUS is a valuable staging modality. Further studies of the role of EUS compared to other modalities such as integrated PET/CT and endobronchial ultrasound (EBUS) are forthcoming.
