[A study on factors influencing survival in stage I ovarian cancer].
Early diagnosis is difficult in ovarian cancer and the prognosis is unfavorable even in stage I case. A total of 131 cases with stage I ovarian carcinoma were treated at our institution, 73 were stage Ia, 13 were stage Ib, 45 were stage Ic and 39 were LPM. To define the criteria for selection of therapy, we retrospectively reviewed the stage I ovarian cancer. The results were as follows: The best survival rate was demonstrated in 96% of LPM cases followed by 73% of endometrioid adeno-carcinoma. Cases with rupture of capsule and with ascites at surgery influenced the 5 year survival rate. We observed no difference in survival rate between the conservative operation (unilateral salpingo-oophorectomy) group and the complete operation (bilateral salpingo-oophorectomy and total hysterectomy) group. Those who had received postoperative chemotherapy showed the longest survival rate of 86%. Evaluation of deaths; 9 of 21 with stage Ic died within 12 months after surgery, and 4 of 7 with stage Iai between 1 and 3 years. The analysis has shown the importance of adequate postoperative treatment and of strict follow-up to guard against recurrence of malignancy in patients with ruptured tumor capsules as well as in those with ascites.
