Multivariate analysis of prognostic factors in patients with ovarian cancer stage I and II.
OBJECTIVE
To evaluate prognostic factors such as surface capsular invasion, rupture of the capsule and intraperitoneal cytology in patients with stage I or II ovarian cancer.


METHODS
Multivariate analysis was performed using 11 clinicopathologic prognostic factors obtained from 183 cases of stage I and II ovarian cancer, which had been surgically treated between 1983 and 1993.


RESULTS
Significant prognostic factors determined by the Kaplan-Meier method were rupture and invasion of the capsule in stage II ovarian cancer. Multivariate analysis showed that spontaneous rupture of the capsule was the only significant factor, and intrapelvic cytology was an important factor without significance. Although capsular rupture caused by the surgeon showed poor prognosis by the Kaplan-Meier method, no significance was observed for this factor by multivariate analysis.


CONCLUSIONS
Multivariate analysis showed that capsular rupture caused by the surgeon did not affect the prognosis in stage I and II ovarian cancer.
