C13.9

Clinical Causes: Long-term tobacco use (smoking cigars, cigarettes, or chewing tobacco) Heavy alcohol consumption Chronic irritation of the hypopharynx due to poor oral hygiene or repeated infections Human papillomavirus (HPV) infection, in some cases History of radiation therapy in the head and neck region Exposure to certain industrial chemicals or carcinogens

Key Symptoms: Persistent sore throat or cough Difficulty swallowing (dysphagia) Sudden or gradual weight loss Hoarseness or changed voice quality Lump or mass in the neck or throat Ear pain or discomfort Unexplained bleeding or foul-smelling breath

Diagnosis Path: Diagnosing hypopharyngeal cancer involves several steps, including a thorough medical history and physical exam. Healthcare providers may use the following diagnostic tools: - Endoscopy with a laryngoscope to visually examine the throat - Biopsy of suspicious tissue samples taken during endoscopy - Imaging tests such as CT scans, MRI, or PET scans to determine the extent of tumor spread - Laryngoscopy for detailed visualization of the hypopharynx Evaluation of lymph nodes in the neck to check for metastasis is also part of the diagnostic process.

Treatment Protocols: Treatment approaches depend on the size, location, and spread of the tumor, as well as the patient’s overall health. Common treatments include: - Surgery to remove the tumor or affected tissues, which may involve partial or total removal of the larynx or hypopharynx - Radiation therapy aimed at destroying cancer cells - Chemotherapy, often used in combination with radiation, to target cancer cells throughout the body - Targeted therapy and immunotherapy might be considered in advanced cases Rehabilitation such as speech therapy and nutritional support may be necessary following treatment to assist with recovery.
