Prognostic risk factors in histopathologic findings were analyzed in the data for one hundred and thirteen patients with uterine endometrial carcinoma who were treated surgically. Univariate survival analysis with Kaplan-Meier methods revealed that the nuclear grade (p less than 0.005), lymph-vascular space invasion (p less than 0.005), histologic grade (p less than 0.01) and histologic type (p less than 0.01) correlated with the patient's prognosis. Among surgical FIGO stages II and III, there was similar significance in the correlations in the nuclear grade (p less than 0.05), lymph-vascular space invasion (p less than 0.0001) and histologic type (p less than 0.05), although there was difference (p less than 0.05) only between grade 1 and grade 3 in the histologic grade. Multivariate survival analysis with a proportional hazard regression model showed that the nuclear grade (p less than 0.005) and lymph-vascular space invasion (p less than 0.01) correlated significantly with the prognosis. The hazard ratios with a 95% confidence interval for each of these factors were 19.2 (3.2-115.7) and 16.9 (2.1-135.3), respectively. The 3-year survival rate was 98% for a hazard ratio less than 64.7, and 45% for one more than 67.4, between which there was a significant difference (p less than 0.0001). And univariate survival analysis of this hazard ratio also revealed strong correlations with the patient's prognosis. These results suggest that it is of great importance to adopt the hazard model including such factors as the nuclear grade and lymph-vascular space invasion in estimating the patient's prognosis and proceeding to adequate post-operative therapy for individual patient.

Histopathologic factors were investigated in the data for ninety-one patients with endometrial carcinoma who were treated surgically. Each of these subjects was reclassified according to the new FIGO surgical criteria (1989) for stages and the relationship between the new classifications and the prognosis of patients was analyzed. One third of the patients (24/72) with clinical FIGO stage I (1983) had extracorporeal spread of the disease and these cases were reclassified as surgical stages II and III. Among clinical stage Ib patients there were many more with extracorporeal spread than among those in clinical stage Ia (p less than 0.005) although there was no difference between the histopathological characteristics (histologic grade, myometrial invasion, cervical involvement, adnexal involvement and pelvic lymph node metastasis) of the stage Ia and Ib groups. Univariate survival analysis revealed that the histologic grade (p less than 0.05), myometrial invasion (p less than 0.05), cervical involvement (p less than 0.005) and pelvic lymph node metastasis (p less than 0.005) correlated with the patient's prognosis. Multivariate survival analysis with the proportional hazard regression model showed that cervical involvement (p = 0.05) and the new stage classification (p = 0.03) correlated significantly with the prognosis. The cumulative 5-year survival rate by clinical stage (1983) was 87% for stage I (Ia: 96%, Ib: 80%) and 72% for stage II, between which no significant difference was determined. The survival rate for stage III was not calculated because there was only one case with stage III disease in this study.(ABSTRACT TRUNCATED AT 250 WORDS)

The basic and clinical efficacies of aztreonam (AZT) were evaluated in obstetric and gynecologic infections during the perinatal period. The results obtained are summarized below. 1. Concentrations of AZT in umbilical venous blood and amniotic fluid showed a good placental transfer of AZT. The rate of placental transfer of AZT was very similar to rates for cephalosporins. 2. Since the clinical efficacy rate of AZT in the treatment of Gram-negative bacterial infections was 80.0%, AZT appears to be a useful drug against Gram-negative bacterial infections.
