Head and neck cancer registry of Japan.

OBJECTIVE

The Head and Neck Cancer Registry, supported by the Japan Society for Head and Neck Cancer, was re-established in 2012 after renewal of the contents and methods of registration.

METHODS

The registry registers patients with previously untreated, histologically confirmed malignant tumors of the head and neck, including the oral cavity, larynx, hypopharynx, oropharynx, nasopharynx, nasal cavity and paranasal sinus, major salivary gland, and cervical nodal involvement with an unknown primary.

RESULTS

The total number of registered patients reached more than 150,000 as of June 2024. We have published reports of important real-world evidence from the registry data.

CONCLUSION

We believe that this nation-wide, organ-based registry aids understanding of the epidemiology and treatment strategies of head and neck cancer, in addition to hospital-based and national cancer registries in Japan.
