Once the tumor cells have invaded the nerve sheath, it may access the growth environment that is beneficial for metastasis 7.
This was the predominant theory for the last 40 years. Through continuous pathological section analysis, it was found that the transfer mode of perineural invasion was continuous, non-jumping, and direct spreading 8. The patterns of perineural invasion widely varies, including complete and incomplete encirclement, concentric lamination, and tangential contact 9.
A more common exist in perineural invasion is tumor cells free inside of the nerve sheath but tumor-nerve contact within the perineurium In fact, there is no agreement regarding the interpretation of perineural invasion among pathologists who conduct microscopic examination of tissue specimens Furthermore, it is necessary to establish a risk model exploring the relationship between nerve-tumor distance and nerve diameter with clinical outcomes Perineural tumor spread is more frequently associated with 15 :.
The biologic mechanism of perineural invasion pathogenesis is not well understood, but a recent theory is that it relates to reciprocal signaling interactions and the acquired capacity of tumor cells to respond to signals within the peripheral nerve, which promote invasion. Some of these such as NGF and other factors, such as neural cell adhesion molecule NCAM , have been shown to have increased expression in head and neck squamous cell carcinoma demonstrating perineural invasion, and may also have a role in its pathogenesis Footnote: Schwann cells mediate perineural invasion.
Dedifferentiated Schwann cells come into direct contact with cancer cells. This direct contact results in the extension of protrusions from the cancer cells. Schwann cells intercalate between cancer cells, thereby promoting cancer dispersal from the tumor and migration toward the neuron. These steps ultimately lead to perineural invasion. Patients with extensive perineural invasion PNI should be offered adjuvant radiation therapy.
Focal perineural invasion is a relative indication for adjuvant therapy. Image-guided radiation therapy is used to verify accurate delivery of intensity-modulated radiation therapy, and may provide an additional advantage in radiotherapeutic management of complex targets close to critical structures, of relevance for head and neck tumors with perineural spread PNS. The role of systemic therapies in the management of perineural invasion and perineural spread remains unclear.

Patients who experience perineural invasion, which has been described in many cancer types, often have poor prognoses, higher risk of local recurrence, and often suffer from severe pain 2. Perineural invasion is a well-recognized phenomenon in head and neck cancers 3 , prostate cancer 4 and colorectal cancer.
A third term, neurotropism, simply means that a tumor has an affinity for growth along nerves. There are three layers of connective tissue covering each nerve, namely the outermost epineurium, the middle perineurium, and the innermost endoneurium 6. The inside part of the nerve is separated from the surrounding tumor by multiple layers of collagen and basement membrane. This anatomical structure serves as a low-resistance plane that provides channels to the tumor cells for spreading along the neural sheaths.
Once the tumor cells have invaded the nerve sheath, it may access the growth environment that is beneficial for metastasis 7. This was the predominant theory for the last 40 years.
