Surgical specimens from 111 patients with Stage I endometrial cancer were reviewed for the presence of lymph‐vascular space invasion by tumor cells. Lymph‐vascular space invasion was noted in 16 cases, and occurred most frequently in poorly differentiated tumors with deep myometrial penetration. Tumor recurrence developed in 44% of patients whose tumors demonstrated lymph‐vascular space invasion as opposed to only 2% of patients without this finding (p < 0.001). Of seven patients with lymph‐vascular space invasion who experienced tumor recurrence, five developed extra‐pelvic metastases. Discriminant function analysis of these data revealed a statistically significant correlation between lymph‐vascular space invasion and tumor recurrence, independent of histologic differentiation of myometrial penetration. These findings suggest that lymph‐vascular space invasion by tumor cells is an important prognostic variable in Stage I endometrial cancer which should be considered in treatment planning.

Five hundred twenty-six patients with invasive cervical cancer, treated at the University of Kentucky from 1964 to 1976, were followed 2-12 years after therapy. One hundred and sixty patients (3 1 %) developed tumor recurrence. Recurrent cancer was noted within 1 year after therapy in 58% of patients and within 2 years of treatment in 76% of patients. Only 6% of patients with recurrent cervical cancer survived 3 or more years. Stage of disease, cell type, lesion size, and the presence of lymph vascular space invasion by tumor cells were all shown to be prognostically significant. The addition of extrafascial hysterectomy to radiation therapy significantly decreased the incidence of recurrence in stage IB cervical tumors 5 cm or more in diameter. Analysis of this data suggests that radical hysterectomy and pelvic lymphadenectomy is as effective as irradiation only in the treatment of large cell squamous carcinomas 2 cm or less in diameter.Cancer 44:2 354 -236 1, 1979.
