Lymph nodal metastases and pathological patterns in cervical cancer: a critical review

We analyzed 8 pathological factors in order to recognize which of them are statistically significant in worsening the stage of cervical cancer. Three factors (external third invasion, CLS, parametrial invasion) are highly significant (p less than 0.001) as regards lymphatic metastases, while no one statistical relation has been found among grading or histotype and cervical canal invasion. Comparing the 8 pathologic factors among themselves, we have observed that parametrium, corpus and CLS are highly related to external third (p less than 0.001); in the same way corpus is related to cervical canal and parametrium to CLS (p less than 0.001).
