American Society of Clinical Oncology guideline for antiemetics in oncology: update 2006.

PURPOSE: To update the 1999 American Society of Clinical Oncology guideline for antiemetics in oncology. UPDATE METHODOLOGY: The Update Committee completed a review and analysis of data published from 1998 thru February 2006. The literature review focused on published randomized controlled trials, and systematic reviews and meta-analyses of published phase II and phase III randomized controlled trials. RECOMMENDATIONS: The three-drug combination of a 5-hydroxytryptamine-3 (5-HT(3)) serotonin receptor antagonist, dexamethasone, and aprepitant is recommended before chemotherapy of high emetic risk. For persons receiving chemotherapy of high emetic risk, there is no group of patients for whom agents of lower therapeutic index are appropriate first-choice antiemetics. These agents should be reserved for patients intolerant of or refractory to 5-HT3 serotonin receptor antagonists, neurokinin-1 receptor antagonists, and dexamethasone. The three-drug combination of a 5-HT3 receptor serotonin antagonist, dexamethasone, and aprepitant is recommended for patients receiving an anthracycline and cyclophosphamide. For patients receiving other chemotherapy of moderate emetic risk, the Update Committee continues to recommend the two-drug combination of a 5-HT3 receptor serotonin antagonist and dexamethasone. In all patients receiving cisplatin and all other agents of high emetic risk, the two-drug combination of dexamethasone and aprepitant is recommended for the prevention of delayed emesis. The Update Committee no longer recommends the combination of a 5-HT3 serotonin receptor antagonist and dexamethasone for the prevention of delayed emesis after chemotherapeutic agents of high emetic risk. CONCLUSION The Update Committee recommends that clinicians administer antiemetics while considering patients' emetic risk categories and other characteristics.

Granisetron in the control of radiotherapy-induced nausea and vomiting: a comparison with other antiemetic therapies.

Radiotherapy-induced nausea and vomiting (RINV) can be one of the most distressing symptoms of radiotherapy treatment, which if incompletely controlled may last for several weeks with fractionated radiotherapy and prevent completion of the planned treatment course. Current treatment guidelines recommend the use of 5-HT(3) receptor antagonists with or without corticosteroids for highly and moderately emetogenic radiotherapy, though only granisetron and ondansetron are currently indicated for RINV in most countries. Granisetron is a potent and highly selective 5-HT(3) receptor antagonist, with demonstrated efficacy in RINV in both placebo-controlled and comparative studies. In this paper the clinical experience with granisetron in RINV is reviewed, and its efficacy and safety compared with other antiemetic therapies.

Effects of recombinant human erythropoietin (rHuEPO) on tumor control in patients with cancer-induced anemia.

It is well recognized that anemia-induced tumor hypoxia is associated with a reduced sensitivity of tumors to radiation and some forms of chemotherapy. Thus, the correction of lower hemoglobin (Hb) concentrations with recombinant human erythropoietin (rHuEPO) can play an essential role by improving tumor oxygenation. Based on evidence from a number of trials, treatment with rHuEPO will effectively ameliorate anemia and improve quality of life. However, one of the most essential prerequisites for achieving this benefit is the use of rHuEPO in agreement with the evidence-based ASCO/ASH-guidelines recommending a target Hb concentration of 12 g/dl (7.44 mmol/l).

Peripheral vascular disease: carotid and vertebral brachytherapy for in-stent restenosis.

For years, intra-arterial brachytherapy has been a recognized method for treating recurrent stenosis after percutaneous transluminal angioplasty and stent placement. However, its use in arteries supplying the brain has not been described to date. We report a case treated with intra-arterial brachytherapy for high-grade recurrent stenoses of the high cervical internal carotid artery and the proximal vertebral artery. At 2-year follow-up, the outcome was successful.

Antiemetics in children receiving chemotherapy.

Only a few studies have been carried out in children on the prevention of chemotherapy-induced acute emesis. 5-HT3 antagonists have been shown to be more efficacious and less toxic than metoclopramide, phenothiazines and cannabinoids. The optimal dose and scheduling of the 5-HT3 antagonists has not been identified. Combinations of a 5-HT3 antagonist and dexamethasone show increased efficacy with respect to 5-HT3 antagonists alone. All pediatric patients receiving chemotherapy of high or moderate emetogenic potential should receive a combination of a 5-HT3 antagonist and dexamethasone to prevent acute emesis. No studies have specifically evaluated antiemetic drugs in the prevention of chemotherapy-induced delayed and anticipatory emesis in children.

Antiemetic therapy for multiple-day chemotherapy and high-dose chemotherapy with stem cell transplant: review and consensus statement.

The objective of this paper is to evaluate the efficacy of modern antiemetic therapy for chemotherapy-induced nausea and vomiting for patients receiving multiple-day or high-dose chemotherapy. Published phase II and phase III studies as well as their personal experiences were evaluated by the authors to develop this consensus statement. The largest published experience with multiple-day chemotherapy is with 5-day cisplatin combination chemotherapy. The introduction of 5-HT3 antagonists greatly improved emetic control. However, day 4-5 nausea as well as delayed nausea and vomiting remains a clinical problem despite the inclusion of dexamethasone. A 5-HT3 antagonist plus dexamethasone is the preferred current option for patients receiving high-dose chemotherapy with stem cell transplant. However, the results do not appear as successful as for highly emetic standard-dose chemotherapy.
