Abstract
Introduction: The objective of this study was to evaluate the prognostic significance of 23 clinical and histopathological variables in relation to disease-free (DFS) and overall survival (OS) in patients
with early stage cervical carcinomas.
Methods: A retrospective analysis of 237 patients with cervical carcinoma, undergoing radical hysterectomy and postoperative irradiation between 1988 and 1997 was conducted. The operative
specimens were subjected to detailed and uniform histopathological work-up. The patients were staged according to the postoperative TNM classification of UICC (1997) guidelines. Mean follow-up
time was 57 (18-124) months.
Results: The 5 and 10-year OS rate was 80.8%, while DFS rates at 5 and 10 years were 76.8% and 75.5%, respectively. In multivariate analysis, blood vessel invasion, pelvic lymph node metastases, tumor diameter, inflammatory stromal reaction at the invasion front, and minimum thickness of uninvolved cervical stroma/parametrial extension, were independent and significant variables. The prognostic index, as an indicator of the patient's place in the prognostic spectrum, defined by the Cox regression model, was able to categorize the patients into three distinct risk groups. The 5-year DFS and OS rates of the low-, intermediate-, and high-risk groups were 97.5%, 86.3%, and 43.8%, vs. 98.8%, 84.5%, and 45.3%, respectively (P<0.0001).
Conclusions: The prognostic index could be a sound basis for an appropriate planning of the following therapeutical strategy for the surgically treated patients with cervical carcinoma. The postoperative TNM classification should be modified, incorporating the blood vessel invasion and the inflammatory stromal reaction at the invasion front, as additional significant prognostic factors.
