Which patient characteristic would limit the use of radiation therapy post-initial treatment in FOM SCC?

• A. Patient age
• B. Depth of tumor
• C. Stenosis
• D. Tumor size

Answer: (C)

The limitation of using radiation therapy post-initial treatment in cases of Floor of Mouth (FOM) squamous cell carcinoma (SCC) can indeed be influenced by the presence of stenosis in the patient's condition. Stenosis refers to the abnormal narrowing of a body passage or space, which can occur in the context of the FOM due to tumor invasion or post-surgical changes. When stenosis is present, especially in the oral cavity or oropharynx, it can complicate the administration of radiation therapy. This is because the altered anatomy may hinder the ability to deliver radiation uniformly and effectively to the targeted tissues, potentially leading to inadequate treatment and increased toxicity. Furthermore, radiation therapy can exacerbate existing anatomical irregularities, leading to complications such as further narrowing, difficulty in swallowing, and the ability to maintain oral hygiene. Thus, the presence of stenosis is a significant consideration in treatment planning and can limit the implementation of post-treatment radiation in patients with SCC originating from the FOM.
