About Oral Mucositis

Oral Mucositis (OM): A serious complication for your patients

A painful inflammatory condition that worsens over time and can be difficult to manage1-3

Severe cases of OM may result in the interruption of a patient’s oncology treatment schedule4

Inflammation is the underlying cause

OM, an inflammation and ulceration of the mucosal membranes in the mouth and throat, is a common side effect of radiation and chemotherapy cancer treatments.1,2

  • Severe pain and inflammation
  • Increased risk of infections
  • Malnutrition
  • Dehydration
  • Difficulty speaking
  • Increased use of opioids

The pathogenesis of OM6*

* Adapted from J Support Oncol 2004;2(1):21–32

  • Radiation and/or chemotherapy causes direct cell death and activates second messengers, leading to upregulation in proinflammatory cytokines
  • Upregulation of proinflammatory cytokines causes injury to mucosal cells and activates pathways that amplify mucosal injury
  • A significant inflammatory cell infiltrate is associated with the mucosal ulcerations

Well-controlled OM is essential to cancer treatment success

When radiation or chemotherapy doses must be reduced or interrupted, the efficacy of cancer therapy and patient survivorship may be compromised9,10

Severe, debilitating OM is most often associated with head and neck malignancies6
  • In one study (n = 204), OM developed in 91% of patients receiving radiation therapy, with or without chemotherapy8
  • The risk of OM was significantly higher among patients receiving a regimen of both chemotherapy and radiation versus those receiving radiation alone (P = 0.002)8
