Malignant Odontogenic Tumours

Scope

The dataset has been developed for the reporting of excision biopsy and resection specimens for malignant primary odontogenic (carcinoma and sarcoma) tumours. For resections of recurrent disease, the reporting guide may be used pragmatically although some data elements may be not applicable nor assessable. Malignant neoplasms arising in the nasal cavity and paranasal sinuses, oral cavity, salivary glands, trachea, pharynx and larynx are dealt with in separate ICCR datasets. Non-odontogenic bone, soft tissue and lymphoma protocols are also dealt with in separate ICCR datasets. In addition, neck dissections and nodal excisions are dealt with in a separate ICCR dataset, and this dataset should be used in conjunction, where applicable.

This dataset is intended for use for primary cancer resections.
