Radiation Associated Dysphagia

I didn’t have trouble swallowing right after my radiation treatment, so why now, years later?

Many people believe that once you have completed radiation treatment, then you are out of the woods. Unfortunately, people can develop side effects from radiation, including difficulty swallowing, months – even years – following the completion of their treatment.

What is late Radiation-Associated Dysphagia?

Also called “late RAD,” radiation-associated dysphagia refers to the stiffening of the muscles and tissues of the mouth, throat and/or esophagus. This can result in impaired or painful swallowing.

What are some complications of late RAD?

· Fibrosis: Stiffening of muscles and tissues

· Xerostomia: Dry mouth

· Odynophagia: Pain when swallowing

· Trismus: Difficulty opening your mouth

· Globus: Sensation of food sticking in your throat or esophagus

· Stricture: Narrowing of the esophagus causing food to get stuck or pass slowly

What can I do if I have late RAD?

You are not alone. Swallowing difficulties not only negatively impact quality of life and social interactions, but they can lead to health issues such as weight loss, dehydration & even pneumonia.

To address your swallowing difficulty, it can be beneficial to seek referrals, helpful resources & a support network.

· Speech-Language Pathologist (SLP)

· Ear, Nose & Throat Physician (ENT)

· Registered Dietician (RD)

· Gastroenterologist (GI)

How can I prevent late RAD?

Unfortunately, there is no way to prevent late RAD, however one can minimize the effects and manage it as much as possible by having a progressive, comprehensive daily exercise and stretching plan.

If you are just beginning treatment for head and neck cancer, be sure to seek a referral to a Speech-Language Pathologist (SLP) who has expertise in treating dysphagia in patients with head and neck cancer for an evaluation of your current swallowing ability. The National Foundation of Swallowing Disorders can provide a referral to an SLP who is board-certified in the treatment of swallowing disorders.

Here are a few examples of what you might expect from a referral to an SLP:

· Assessment of your swallow: A clinician will either x-ray your throat/esophagus or pass a scope through your nose while you swallow.

· Diet modifications: Some people may need softer/smoother foods or thicker liquids to swallow safely. Non-oral nutrition (feeding tube) may be considered if indicated.

· Compensatory strategies: There may be postures or techniques that can help protect your airway and help you more easily swallow foods/liquids.

· Swallowing interventions: There are exercises for your tongue and throat that may be helpful depending on the severity of your swallowing problem. If you have a narrowing of your esophagus, a doctor may consider a dilation/stretching.
