Local recurrence underreporting in rectal cancer registry suggests improved definitions and reporting accuracy for metastatic disease.
There was a significant underreporting of local recurrence in the SCRCR.

Clarifying the definition of local recurrence and stressing the importance of reporting local recurrence regardless of metastatic disease or palliative treatment may improve data accuracy.
