Background and purpose Both lymphovascular invasion (LVI) and non-nodal tumor deposits (TDs) are essential prognostic risk factors for colorectal cancer that many oncologists may not be aware of. This study aimed to detect the incidence of reporting of the state of the LVI and non-nodal TDs with operable colorectal malignancy, which are very important prognostic risk factors. Patients and methods Reporting of LVI and non-nodal TDs were traced in 900 patients (818 retrospective and 82 prospective individuals) with cancer of the colon and the rectum. The ability of improving the incidence of reporting was estimated by comparison of incidence of reporting in both groups. Results Percentage of reporting of LVI was 39% in the retrospective group and 49.9% in the prospective group, while reporting of non-nodal TDs was 7.228% in the retrospective group and 24.24% in the prospective group. There was a statistically significant difference between reporting of non-nodal TDs, prospective patients over retrospective patients (P<0.0001); while there was no statistically significant difference between reporting in retrospective and prospective patients in the LVI with P value of 0.865. Conclusion There were inadequate reporting of both non-nodal TDs and LVI in retrospective patients with improvement in prospective patients although statistically nonsignificant in the LVI, which may necessitate a new staging system that could accommodate all this prognostic risk factors.
