Gene expression analysis of the concomitant existence of lymphovascular and perineural invasion in colorectal cancer
The invasion of cancer cells into the peritumoral, lymph node and perineural system could be detrimental on cancer patients. In colorectal cancer (CRC) patients, the presence of lymphovascular (LVI) and/or perineural (PNI) invasion could significantly influence on the survival rates, treatment optio...

The invasion of cancer cells into the peritumoral, lymph node and perineural system could be detrimental on cancer patients. In colorectal cancer (CRC) patients, the presence of lymphovascular (LVI) and/or perineural (PNI) invasion could significantly influence on the survival rates, treatment options and recurrence tendencies. To date, no study has analyzed the molecular profile of the concomitant existence of LVI and PNI in CRC.
