Abstract
Purpose
Surgery remains the curative treatment of choice for colorectal cancer (CRC). However, to our knowledge, no report has addressed the usefulness of additional regional lymph node dissection for primary CRC that has invaded another colon region.
Methods
We reviewed the clinicopathological characteristics and outcomes of eight patients who underwent surgery between March, 2005 and August, 2014, for CRC that invaded another region of the colon.
Results
Five patients underwent additional regional lymph node dissection in the area of the invaded colon and one patient had lymph node metastasis in the region. Two of three patients who did not undergo additional regional lymph node dissection were found to have regional lymph node recurrences in the area during the follow-up period. Although there was no statistical correlation between extra-regional lymph node metastasis and clinicopathological or operative factors, the patients with extra-regional lymph node metastasis or recurrence had primary regional lymph node metastasis.
Conclusion
For curative intent, surgeons may need to perform additional regional lymph node dissection for primary CRC invading another colon region.
