Non-Hodgkin's Lymphoma in the Elderly: A Tale of Successes and Future ChallengesAs 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.

Further Thoughts on a Rare EntityPrimary neuroendocrine neoplasms of the lung represent a clinical spectrum of tumors ranging from the relatively benign and slow-growing typical carcinoid to the highly aggressive small-cell lung carcinoma. The rarity of carcinoids has made the role of radiation therapy in their management controversial. This review considers the results of published studies to generate treatment recommendations and identify areas for future research. Surgery remains the standard of care for medically operable disease. Histology plays the most important role in determining the role of adjuvant radiation. Resected typical carcinoids likely do not require adjuvant therapy irrespective of nodal status. Resected atypical carcinoids and large-cell neuroendocrine carcinomas have a significant risk of local failure, for which adjuvant radiation likely improves local control. Definitive radiation is warranted in unresectable disease. Palliative radiation for symptomatic lesions has demonstrated efficacy for all histologies. Collaborative group trials are warranted.

Chemotherapy After Surgery for Stage II Colon Cancer: Clarifying the ControversyTo treat, or not to treat-the decision to use adjuvant chemotherapy plagues medical oncologists and patients harnessed with the diagnosis of stage II colon cancer. A look to the literature does not simplify the decision, as significant controversy exists regarding the magnitude of benefit associated with 6 months of adjuvant chemotherapy. Dr. Kopetz and colleagues provide a well-organized review of the current literature examining the benefit of adjuvant chemotherapy in stage II disease, and discuss potential prognostic markers that may help determine who would most likely benefit from treatment.

Irinotecan/Cisplatin in Advanced, Treated Gastric or Gastroesophageal Junction CarcinomaWe conducted a phase II study to assess the response rate and toxicity profile of the irinotecan (CPT-11, Camptosar) plus cisplatin combination administered weekly to patients with at least one previous chemotherapy for advanced adenocarcinoma of the stomach or gastroesophageal junction. Patients with histologic proof of adenocarcinoma of the stomach or gastroesophageal junction with adequate liver, kidney, and bone marrow functions were treated with 50 mg/m² of irinotecan plus 30 mg/m² of cisplatin, both administered intravenously 1 day a week for 4 consecutive weeks, followed by a 2-week recovery period.

Contemporary Management of Prostate Cancer With Lethal PotentialScreening for prostate cancer by determining serum prostate-specificantigen (PSA) levels has resulted in a stage migration such thatpatients with high-risk disease are more likely to be candidates for curativelocal therapy. By combining serum PSA, clinical stage, and biopsyinformation-both Gleason score and volume of tumor in the biopsycores-specimen pathologic stage and patient biochemical disease-freesurvival can be estimated. This information can help patients and cliniciansunderstand the severity of disease and the need for multimodaltherapy, often in the context of a clinical trial. While the mainstays oftreatment for local disease control are radical prostatectomy and radiationtherapy, systemic therapy must be considered as well. A randomizedtrial has shown a survival benefit for radical prostatectomy inpatients with positive lymph nodes who undergo immediate adjuvantandrogen deprivation. Clinical trials are needed to clarify whether adjuvantradiation therapy after surgery confers a survival benefit. PSAis a sensitive marker for follow-up after local treatment and has proventhat conventional external-beam irradiation alone is inadequate treatmentfor high-risk disease. Fortunately, the technology of radiationdelivery has been dramatically improved with tools such as three-dimensionalconformal radiation, intensity-modulated radiation therapy,and high-dose-rate brachytherapy. The further contributions of pelvicirradiation and neoadjuvant, concurrent, and adjuvant androgen deprivationtherapy have been defined in clinical trials. Future managementof high-risk prostate cancer may be expanded by clinical trialsevaluating neoadjuvant and/or adjuvant chemotherapy in combinationwith androgen deprivation.

Contemporary Management of Prostate Cancer With Lethal PotentialThe article by Davis et al is importantfor several reasons.First, it reminds us about themost lethal phenotype in patients withapparently localized prostate cancer.This subgroup is easily forgotten intoday's era of PSA screening becausethe majority of patients now diagnosedwith prostate cancer are classified aslow risk. Second, there have been few,if any, good reviews that define theissues, including the definition ofhigh-risk disease, the effectiveness ofthe major treatments (ie, radical prostatectomy,radiation therapy, and theirneoadjuvant or adjuvant supplementaltherapies), and the current gaps inour knowledge of these issues.

Managing the Peritoneal Surface Component of Gastrointestinal Cancer: Part 2Until recently, peritoneal carcinomatosis was a universally fatalmanifestation of gastrointestinal cancer. However, two innovations intreatment have improved outcome for these patients. The new surgicalinterventions are collectively referred to as peritonectomy procedures.During the peritonectomy, all visible cancer is removed in an attemptto leave the patient with only microscopic residual disease. Perioperativeintraperitoneal chemotherapy, the second innovation, is employed toeradicate small-volume residual disease. The intraperitoneal chemotherapyis administered intraoperatively with moderate hyperthermia.Part 1 of this two-part article, which appeared in the January issue,described the natural history of gastrointestinal cancer with carcinomatosis,the patterns of dissemination within the peritoneal cavity, andthe benefits and limitations of peritoneal chemotherapy. Peritonectomyprocedures were also defined and described. Part 2 discusses the mechanicsof delivering perioperative intraperitoneal chemotherapy andthe clinical assessments used to select patients who will benefit fromcombined treatment. The results of combined treatment as they vary inmucinous and nonmucinous tumors are also discussed.

Understanding the Pathobiology of Chemotherapy-Induced Nausea and VomitingImproved understanding of the physiologic and neuropharmacologicmechanisms underlying chemotherapy-induced nausea andvomiting (CINV) has driven significant progress in the treatment ofCINV over the past 2 decades. Recognition of the role of neurotransmittersand their receptors in the process of CINV has been central tothis progress. Initial attention focused on dopamine, then on serotonin,and most recently on substance P, which has yielded a usefulnew class of antiemetic medications known as selective neurokinin-1receptor antagonists. Preclinical studies of these neurokinin-1 receptorantagonists suggested that they would demonstrate broad antiemeticactivity in acute emesis, demonstrate activity against cisplatininduceddelayed emesis, be well tolerated, and contribute to enhancedefficacy when used in combination with other classes of antiemetics.These suggestions appear to have been largely borne out in clinicaltrials. Pharmacogenomics may offer a means to further extend andapply our understanding of CINV by enabling more selective targetingof antiemetic therapies. To date, the application of pharmacogenomicsto CINV has focused on variations in the metabolism of serotoninreceptor antagonists by CYP 450 genotype and variations in the5-HT3 receptor gene itself.
