Are lymph node ratio and surgical quality strong prognostic factors of rectal cancer : results from a single referral centre?
LNR is an independent prognostic factor of OS and ORFS. In line with the principles of optimal surgical management, the quality of TME and lymph node yield are essential technical requirements.
Our results confirm the finding that 'acquired' immune responses are not ubiquitous across all invertebrate-pathogen interactions. We discuss why we may have observed no effect in this study, with focus on the mechanistic basis of the RNAi pathway.
