| Outline of Final Research Achievements |
Although most smooth muscle neoplasms detected in the uterus are benign, uterine leiomyosarcoma (Ut-LMS) is extremely malignant with high rates of recurrence and metastasis. CAVEOLIN1 (CAV1) levels in the epithelial cells of some carcinomas have been reported to increase during tumor progression. We herein evaluated the relationship between CAV1 expression and the pathological features of patients diagnosed with uterine mesenchymal tumors. No clinical link was observed between CAV1 expression and the malignancy of uterine mesenchymal tumors. CAV1 expression was decreased in the normal myometrium, whereas it was strongly expressed in uterine mesenchymal tumors. However, CAV1 was not a potential biomarker to distinguish Ut-LMS from other uterine mesenchymal tumors. The perivascular expression of CAV1 was observed in all types of uterine mesenchymal tumors and myometria. The present study suggest that CAV1 may not act as a potential biomarker of uterine malignant mesenchymal tumors.
