Treatment may involve surgery, radiotherapy, or chemotherapy, alone or in combination.Surgical Treatment
Surgical treatment may involve partial or full removal of the tumour. Neighbouring tissues and structures may or may not be removed, depending on their involvement in the tumour’s structure and spread. Full removal of the larynx may be necessary in some cases. Adjunct Treatment
Adjunct treatment, most commonly the administration of chemotherapy or radiotherapy, may be necessary. Chemotherapy or radiotherapy may be necessary singly, in combination with each other, or in combination with surgery. Adjunct treatment may be necessary prior to surgical treatment, alongside surgical treatment, or after surgical treatment. Clinical decision-making can be difficult in circumstances where the patient is unable to access necessary adjunct treatment. Multi-Disciplinary Treatment
Often, successful treatment of and recovery from laryngeal cancer will involve expertise outside of the realms of surgery or oncology. Physical therapists, occupational therapists, speech therapists, psychiatrists, psychologists, oral/maxillofacial surgeons,  dentists, neurologists, neurosurgeons, and endocrinologists may all become involved in the care of patients with laryngeal cancer. Epidemiology
Incidence is five in 100,000 (12,500 new cases per year) in the US. The American Cancer Society estimated that 9,510 men and women (7,700 men and 1,810 women) would be diagnosed with and 3,740 men and women would die of laryngeal cancer in 2006.According to the GLOBOCAN 2018 estimates of cancer incidence and mortality produced by the International Agency for Research on Cancer, there were 177,422 new cases of laryngeal cancer worldwide in 2018 (1.0% of the global total.) Among worldwide cancer deaths, 94,771 (1.0%) were due to laryngeal cancer.
The examination of the larynx requires some expertise, which may require specialist referral.The physical exam includes a systematic examination of the whole patient to assess general health and to look for signs of associated conditions and metastatic disease. The neck and supraclavicular fossa are palpated to feel for cervical adenopathy, other masses, and laryngeal crepitus. The oral cavity and oropharynx are examined under direct vision. The larynx may be examined by indirect laryngoscopy using a small angled mirror with a long handle (akin to a dentists mirror) and a strong light. Indirect laryngoscopy can be highly effective, but requires skill and practice for consistent results. For this reason, many specialist clinics now use fibre-optic nasal endoscopy where a thin and flexible endoscope, inserted through the nostril, is used to clearly visualise the entire pharynx and larynx. Nasal endoscopy is a quick and easy procedure performed in clinic. Local anaesthetic spray may be used.If there is a suspicion of cancer, biopsy is performed, usually under general anaesthetic. This provides histological proof of cancer type and grade. If the lesion appears to be small and well localised, the surgeon may undertake excision biopsy, where an attempt is made to completely remove the tumour at the time of first biopsy. In this situation, the pathologist will not only be able to confirm the diagnosis, but can also comment on the completeness of excision, i.e., whether the tumour has been completely removed.
