Carcinomas of the Oral Cavity

Scope

The dataset has been developed for the reporting of resection and excisional biopsy specimens of malignancies of the oral cavity, including mucosal lip and tongue (mucosal carcinomas, minor salivary gland malignancies, and neuroendocrine tumours). For resections of recurrent disease, the reporting guide may be used pragmatically although some data elements may be not applicable nor assessable. Incisional biopsies and other biopsy specimens are not included in this dataset. Mucosal melanoma, lymphomas and sarcomas are 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.

For additional independent (multicentric) tumours, complete a separate dataset for each.
