Clinical usefulness of color doppler ultrasound in patients with endometrial hyperplasia and carcinoma

Abstract

At the microstructural level, bones remodel throughout life. This process is recorded in bone cortex as osteons. A more comprehensive understanding of the interaction between genetic regulation and environmental factors in osteon remodeling will increase the value of this skeletal record and enable more accurate reconstruction of individual life histories. The purpose of this study was to examine the contribution of maternal lineage to normal age and sex variation in osteon remodeling dynamics in Macaca mulatta. Femoral cross sections from 57 Cayo Santiago‐derived rhesus macaques representing five matrilines were examined to evaluate the effect of genetic relatedness on osteon remodeling dynamics. Analysis of variance revealed an effect of maternal lineage on osteon area and Haversian canal area. The other variables did not differ significantly among matrilines. Analysis of covariance revealed no significant interactions among age, sex, and matriline for any of the microstructural variables. Am J Phys Anthropol 121:000–000, 2003. © 2003 Wiley‐Liss, Inc.

Assessment of Myometrial Invasion in Endometrial Cancer by Transvaginal Sonography, Doppler Ultrasonography, Magnetic Resonance Imaging and Frozen Section

“…Some studies have assessed the blood flow characteristics of the uterine artery, 17,11 whereas others have evaluated directly the blood flow characteristics of intratumoral arteries. 26,27 Cheng et al 26 have shown the usefulness of TV-CDU in predicting myometrial tumor spread by using blood flow resistance indices. 28 However, Develioglu et al 17 have shown the unreliability of predicting tumor spread using such indices.…”

Clinical Usefulness of 3-Dimensional Sonography and Power Doppler Angiography for Diagnosis of Endometrial Carcinoma

“…1,2 However, the usefulness of this parameter to discriminate between benign and malignant endometria has shown contradictory results. 3,4 A progressive increase in angiogenesis has been implicated in the progression from endometrial hyperplasia to invasive carcinoma, 5 and color Doppler sonography is a technique that allows in vivo assessment of tumoral angiogenesis. 6 Both premises can explain why this examination has been proposed for discriminating between benign and malignant endometria [7][8][9][10][11][12] and to predict tumoral extension before surgery.…”

Intérêt de l’échographie endovaginale préopératoire dans l’évaluation de l’infiltration myométriale des adénocarcinomes de l’endomètre

“…Le rôle du Doppler pulsé ou couleur dans l'évaluation de l'invasion myométriale est controversé [19,[25][26][27]. Le cancer de l'endomètre s'associe à une hypervascularisation voire une néovascularisation endométriale et sous-endométriale, avec une diminution des index de résistance (IR) et des index de pulsatilité de l'artère utérine, ainsi qu'une perte de l'encoche protodiastolique.…”
