Dysphagia
|May 23, 2026
Summary
Dysphagia (swallowing difficulties) varies significantly by cancer type, affecting head and neck and gastrointestinal cancers most. Understanding these cancer-specific swallowing profiles is key for targeted patient care and rehabilitation.
Area of Science:
- Oncology
- Speech-Language Pathology
- Gastroenterology
Background:
- Dysphagia is prevalent in cancer patients but poorly understood beyond head and neck cancers.
- Characterizing swallowing profiles across diverse cancer types is crucial for effective supportive care and rehabilitation strategies.
Purpose of the Study:
- To analyze swallowing safety and efficiency impairments in a large cohort of adult cancer patients with various diagnoses.
- To identify differences in dysphagia prevalence and patterns across 12 cancer types using the DIGEST scale.
- To correlate videofluoroscopic swallowing study (VFSS) findings with clinical outcomes and identify specific physiologic deficits.
Main Methods:
- Analysis of 10,677 VFSS studies from 6,423 adult cancer patients across 12 diagnoses (2016-2021).
- Utilized the Dysphagia Impairment Severity Scale (DIGEST) for grading swallowing safety and efficiency.
- Employed multivariable mixed-effects ordinal logistic regression to assess differences in DIGEST impairment across cancer types.
- Examined physiologic impairments using the Modified Barium Swallow Impairment Profile (MBSImP) in a subset of 704 studies.
Main Results:
- Dysphagia frequency and patterns (safety vs. efficiency) differed significantly across cancer types (p < 0.05).
- Highest overall dysphagia rates were observed in patients with multiple cancers including head and neck (HN) (71%) and gastrointestinal (GI) (64%) cancers.
- Safety impairments were most common in HN, GI, and central nervous system (CNS) cancers, while efficiency deficits predominated in HN and CNS cancers.
- Pharyngeal swallow initiation, anterior hyoid excursion, and laryngeal vestibular closure were the most frequent physiologic impairments.
Conclusions:
- Swallowing impairment profiles exhibit significant variation based on cancer type, indicating distinct underlying physiologic targets.
- Findings support the development of cancer-specific dysphagia management pathways.
- Integrating both physiologic (MBSImP) and functional (DIGEST) metrics is essential for optimizing dysphagia rehabilitation in cancer patients.

01:27Esophageal Achalasia
Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide (VIP)...
01:25Deglutition
Swallowing, otherwise known as deglutition, facilitates the transport of food from the mouth to the stomach. It is a multifaceted process that involves both the tongue and the muscles of the throat and esophagus. Saliva and mucus aid in this process, which takes approximately 4 to 8 seconds for semi-solid or solid food and around 1 second for liquids or very soft food.
Swallowing can be divided into three stages: the voluntary phase, the pharyngeal phase, and the esophageal phase. Although the...

01:24Upper GI Series: Barium Swallow
The Barium Swallow Study, or a Barium Esophagogram, is a diagnostic imaging method used to visualize the upper gastrointestinal (GI) tract, including the esophagus, stomach, and small intestine. It employs barium sulfate, a radiopaque contrast material, to provide clear images of the upper digestive system, helping to identify abnormalities, diseases, or structural issues.

02:18Cancer
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
01:26Esophageal Strictures-II: Clinical Features and Management
Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

02:43Mouse Models of Cancer Study
Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...
