Eighty-eight patients with figo Stage Ib and IIa squamous cell carcinoma of the cervix underwent radical hysterectomy with pelvic and paraaortic lymphadenectomy. The records and histopathologic material were reviewed to determine the prognostic significance of vascular channel involvement and deep stromal penetration by tumor. Seventy-four patients (84%) were alive and free of disease for more than 2 years and 14 (16%) developed recurrent carcinoma within that time. A positive correlation was found between depth of stromal penetration by tumor and the degree of vascular channel involvement (p<0.05). Vascular involvement in itself did not significantly affect nodal status, survival or the rate of recurrence. Depth of penetration was associated with a higher incidence of positive nodes (p<0.05). There was a trend towards a lower survival rate and a higher recurrence rate in patients with deep stromal penetration as compared to those with superficial tumors. Microscopic nodal disease increased the rate of recurrence and had an adverse effect on survival. The combination of deep tumor penetration and positive nodes in the same patient was associated with the highest recurrence rate and the lowest survival (p<0.05). Nodal status was a more significant prognostic indicator than depth of tumor penetration because patients with deeply penetrating tumors and positive nodes had more than twice the recurrence rate than did patients with deep tumors and negative nodes. Postoperative radiation therapy was beneficial to patients whose tumor demonstrated deep stromal penetration and microscopic metastases to pelvic lymph nodes.
