Abstract: Background: The extension of the metastatic lymph nodes through the capsule to the
adipose tissue in the perinodal or extra-nodal defines the extra-nodal extension (ENE). ENE represents
an important prognostic factor in multiple cancers, which is considered as a prognostic parameter
in different tumor-node-metastasis (TNM) classifications.
Introduction: Colorectal cancer (CRC) is ranked third in order of frequency, after successively
lung and breast cancer. Lymph node metastasis has been validated as a significant negative prognostic
factor for survival in colorectal cancer (CRC), which is improved by the adjuvant. Despite
the use of ENE as an important and validated prognostic factor in multiple cancers, ENE is not yet
taken into account in the CCR staging system.
Method: The present short review aims to discuss the prognostic impact of ENE on CRC according
to the emerging evidence. To conduct this study, we have reported the results of all available
studies following the scientific rationale in three parts: retrospective studies, prospective studies,
and meta-analyses.
Result: ENE has a negative impact on the prognosis of colorectal cancer but is not yet used in practice
in colorectal cancer.
Conclusion: We, therefore, propose to carry out randomized clinical trials to study this subject better
and strengthen its value in management strategies.
