We examined the effectiveness of hypertensive intra-arterial chemotherapy for endometrial carcinoma using transvaginal Doppler ultrasound and magnetic resonance imaging. Angiotensin II, 100 mg cisplatin, and 40 mg doxorubicin were prescribed for 8 patients with endometrial carcinoma (3 stage Ia; 3 stage Ib; 2 stage II). The resistance index (RI) was obtained for intratumoral blood flow velocity waveforms by transvaginal Doppler ultrasound and changes in RI (delta RI: differences before and after chemotherapy) were calculated. The tumor volume (TV) was also evaluated, based on the T2-weighted image of magnetic resonance imaging (MRI). The decrease in tumor size [DR-T: (TV before chemotherapy--TV after chemotherapy)/TV before chemotherapy x 100] was determined. RI measurements did not correlate with TV, either before or after chemotherapy. The delta RI varied from 0.007 to 0.615 (mean: 0.207) and DR-T varied from 20.1% to 65.0% (mean: 45.5%). The correlation between delta RI and DR-T [DR-T = 23.5 + 167.2 (delta RI)-165.6 (delta RI)2; R2 = 0.772, p < 0.05] was significant. Therefore, we confirmed the effectiveness of hypertensive intra-arterial chemotherapy for endometrial carcinoma using both transvaginal Doppler ultrasound and MRI.

The renin-angiotensin system (RAS) is well known as regulator of electrolytes and blood pressure. Besides this function, there are numerous studies supporting the idea of a local tissue RAS. This system controls the local activity of the different RAS family members, especially of the functional proteins Angiotensin II and Angiotensin (1-7). Those antagonistically acting proteins have been described to be expressed in different organ systems including the human reproductive tract. Therefore, this local RAS has been suspected to be involved in the control and regulation of physiological and pathological conditions in the female reproduction tract. This review of the available literature summarizes the physiological influence of the RAS on the follicular development, ovarian angiogenesis, and placental- and uterine function. In addition, in the second part the role of the RAS concerning ovarian- and endometrial cancer becomes elucidated. This section includes possible novel therapeutic strategies via inhibition of RAS-mediated tumor growth and angiogenesis. Looking at a very complex system of agonistic and antagonistic tissue factors, it may be supposed that the RAS in the female reproduction tract will be of rising scientific interest in the upcoming years.
