Misoprostol, a synthetic analog of prostaglandin E1, has anti-inflammatory and mucosa-protecting properties. The objective of this study was to evaluate the efficacy of misoprostol oral rinse in reducing the severity of oral mucosal injury caused by high-dose chemotherapy.

Mucositis is a clinically important and sometimes dose-limiting complication of cancer therapy. Mucositis lesions can be painful, affect nutrition and quality of life, lead to sepsis, and have significant economic impact. Recent modeling of the toxicity has been based on the continuum of clinical signs and symptoms of mucositis involving the alimentary tract, including both oral and gastrointestinal sites. The pathogenesis of oral and gastrointestinal mucositis is multifactorial and complex. In recent years, there has been a substantial increase in both basic and clinical research related to mucosal injury in cancer patients. Since most of this research has been directed to oral mucositis, the present review principally addresses this component of the toxicity. Morbidity, economic impact, pathogenesis and clinical course of mucositis are discussed. In addition, several agents in clinical development for mucositis are discussed in the context of the current pathobiologic model as well as the recently updated evidence-based clinical management guidelines.

Mucositis is a significant complication of cancer therapy, with important clinical and economic implications. In June 2005, the Mucositis Study Group of the Multinational Association of Supportive Care in Cancer/International Society for Oral Oncology (MASCC/ISOO) conducted an evidence-based update review of the literature on mucositis. The goal of this literature review is to update previously published guidelines for the management of mucositis. This article reports the findings of the subgroup charged with reviewing the literature related to amifostine.

Alimentary mucositis is a significant complication of cancer therapy, with important clinical and economic implications. In June 2005, the Mucositis Study Group of the Multinational Association of Supportive Care in Cancer/International Society for Oral Oncology conducted an evidence-based review of the literature on alimentary mucositis. The goal of this literature review was to update previously published guidelines for the management of mucositis. This article reports the findings of the subgroup charged with reviewing the literature related to anti-inflammatory interventions. Considerable preclinical and clinical evidence suggests that the use of anti-inflammatory agents may be a promising approach to reduce the severity of mucositis. However, there was not enough evidence to support any new guidelines advocating the use of any specific anti-inflammatory intervention. Thus, there is a need for well-designed clinical trials evaluating the use of anti-inflammatory agents in the management of mucositis.

CuraGen is developing velafermin (CG-53135), human fibroblast growth factor-20 administered intravenously, for the potential treatment and prevention of oral mucositis (OM). By December 2004, phase II trials for the prevention of OM in cancer patients undergoing bone marrow transplant had been initiated, and in September 2005 CuraGen indicated that results from this study will be reported during the first quarter of 2006.
