Prognostic factors associated with radical hysterectomy failure.
Two hundred seventy-five patients who underwent radical hysterectomy and pelvic lymphadenectomy for FIGO stage IB carcinoma of the cervix between 1961 and 1982 were retrospectively analyzed to identify specific risk factors associated with treatment failure. Patients were classified as high or low risk on the basis of tumor spread to pelvic lymph nodes or surgical margins. Thirty-eight patients had tumor involvement of pelvic nodes or surgical margins. Despite postoperative whole pelvis radiation therapy in 88% of patients, 13 (34.2%) developed recurrence. All patients with involved nodes or margins who recurred died of disease. Patients with pelvic lymph node or surgical margin involvement clearly constitute a high risk group and should be considered candidates for some form of adjuvant therapy. Two hundred thirty-seven patients had negative nodes and clear surgical margins. There were 18 recurrences (7.6%) in this group. Pathologic specimens were reviewed to evaluate additional histologic criteria which might identify those patients at greatest risk for tumor recurrence in this low risk group. Patients whose tumors contained vascular-lymphatic space invasion or adenomatous histologic components recurred more frequently than patients whose tumors did not (P less than 0.05). Eighty-three percent of low risk patients who recurred had tumors with at least one of these features. Degree of differentiation and depth of invasion did not correlate with risk of recurrence. Prospective randomized trials are needed to determine the effectiveness of postoperative adjuvant therapy for patients at risk for recurrent disease.
