This study suggests a role for regular follow-up computed tomography scans within 6 months postoperatively and tumour marker assays for the early detection of ovarian metastasis in premenopausal women after primary surgery, especially in colonic patients with poor prognostic factors.

The depth of submucosal invasion, cell differentiation, and tumor cell dissociation were significant pathologic predictors of LN metastasis in SICC. Because SICC is associated with a considerable risk of LN metastasis, local excision may be performed carefully in SICC without adverse features.
