Laryngeal Cancer Treatment (PDQ®): Treatment - Health Professional Information [NCI] - General Information About Laryngeal Cancer

Supraglottic cancers typically present with sore throat, painful swallowing, referred ear pain, change in voice quality, or enlarged neck nodes. Early vocal cord cancers are usually detected because of hoarseness. By the time they are detected, cancers arising in the subglottic area commonly involve the vocal cords; thus, symptoms usually relate to contiguous spread.

The most important adverse prognostic factors for laryngeal cancers include increasing T stage and N stage. Other prognostic factors may include sex, age, performance status, and a variety of pathologic features of the tumor, including grade and depth of invasion.[6]

Prognosis for small laryngeal cancers that have not spread to lymph nodes is very good with cure rates of 75% to 95% depending on the site, tumor bulk,[7] and degree of infiltration. Although most early lesions can be cured by either radiation therapy or surgery, radiation therapy may be reasonable to preserve the voice, leaving surgery for salvage. Patients with a preradiation hemoglobin level higher than 13 g/dL have higher local control and survival rates than patients who are anemic.[8]

Locally advanced lesions, especially those with large clinically involved lymph nodes, are poorly controlled with surgery, radiation therapy, or combined modality treatment. Distant metastases are also common, even if the primary tumor is controlled.

Intermediate lesions have intermediate prognoses, depending on site, T stage, N stage, and performance status. Therapy recommendations for patients with these lesions are based on a variety of complex anatomic, clinical, and social factors, which should be individualized and discussed in multidisciplinary consultation (surgery, radiation therapy, and dental and oral surgery) prior to prescribing therapy.

Patients treated for laryngeal cancers are at the highest risk of recurrence in the first 2 to 3 years. Recurrences after 5 years are rare and usually represent new primary malignancies. Close, regular follow-up is crucial to maximize the chance for salvage. Careful clinical examination and repetition of any abnormal staging study are included in follow-up, along with attention to any treatment-related toxic effect or complication.
