title: [The reliability of the grading assessment of the biopsy samples in malignant colorectal neoplasms].
abstract: The authors evaluate the results of preoperative bioptic grading compared with those obtained from postoperative specimens. Altogether, there was nonagreement in 45% of cases; therefore there is the risk of underestimating the biological aggressiveness of the disease. In fact, 68% of patients who were assessed as G1 in preoperative staging were found to have a higher degree of neoplastic dedifferentiation.
