What is another word for perineural invasion?
Pronunciation: [pˈɛɹɪnjˌuːɹə͡l ɪnvˈe͡ɪʒən] (IPA) 
Perineural invasion (PNI) refers to the growth and spread of cancer cells around nerves. It is an important factor in cancer staging as PNI indicates a more aggressive tumor and a higher risk of recurrence. There are several synonyms for this term including nerve involvement, intraneural invasion, and neural spread. In addition, PNI can also be referred to as neurotropism, which describes cancer cells' tendency to grow along the nerves and possibly use them as a pathway for metastasis. Accurate and precise communication between healthcare professionals regarding the presence or absence of PNI is essential in formulating the most appropriate cancer treatment plan for patients.
