Conclusion
In conclusion the 8th ediiton head and neck AJCC cancer staging manual incorporates signficiant changes.
Here we highlight some of the pertinent changes relevant to radiologists including:
- DOI,
which is a pathological rather than a radiological measurement,
which has changed the staging of some head and neck tumours.
- HPV +ve and HPV -ve SCC - the former being small,
well defined,
and less likely to invade local structures,
whereas the latter tend to be large,
ill defined,
invade surrounding structures and demonstrate necrotic rather than cystic lymph node metastases.
- ENE is ultimately a pathological diagnosis,
with suggestive radiological features including increased size,
necrosis,
and ill-defined borders
- Neck nodal metastasis with an unknown primary,
depending on HPV and EBV status will be diagnosed as either a oropharyngeal or nasopharyngeal cancer respectively.
These findings are important to guide general radiologists and neuroradiologists alike in guiding reporting,
management,
and contributing to MDM discussion.
