Color and pulsed Doppler ultrasound examinations were done on 11 normal volunteers (NU) and 286 patients that consisted of cervical carcinoma (CC), leiomyoma and/or adenomyosis (M), endometrial carcinoma (EC), trophoblastic disease (TD), benign ovarian tumor (BO), Krukenberg tumor (KT) and ovarian carcinoma (OC). The vascularity was based on the resistance index (RI) and maximum blood flow velocity (Vmax). In uterine disease, there was significant difference (p less than 0.01) among each group, except but one correspondence between NU and CC with RI, and there was significant difference (p less than 0.001) between NU and M, CC and M with Vmax. In ovarian disease, there was significant difference among each group with RI, and there was no significant difference among each group with Vmax. Therefore, Doppler ultrasound is a useful diagnostic tool for assessing gynecologic tumor vascularity.

Gynecologic anatomy is consistently depicted with MRI. Abnormal developmental anatomy is also well assessed. In cases of complete or partial vaginal agenesis where ultrasound is equivocal, MRI can be definitive. The various subtypes of uterine anomalies are well delineated with MRI. MRI is the optimal technique in the therapeutic evaluation of leiomyomas, because the number, size, location, and degeneration can be documented. It is particularly useful in the identification of the ovaries in the presence of an enlarged leiomyomatous uterus. Adenomyosis, an often neglected diagnosis, is distinguishable from leiomyomas. In the setting of an equivocal ultrasound, MRI is useful in discerning whether a mass is ovarian or uterine in origin. Endometriosis, a disease routinely diagnosed and staged by laparoscopy, does have a typical MR appearance and therefore can usually be differentiated from other adnexal masses. Dermoids are readily diagnosed with MRI. Other adnexal masses do not have a specific MR appearance and morphologic criteria as used with ultrasound or CT must be relied upon in suggesting whether or not the mass is benign or malignant. MRI is the procedure of choice in the staging of cervical and endometrial cancer.

Estrogen biosynthesis (aromatase activity) was investigated in human adenomyosis tissue and compared with that of the normal myometrium, endometrium, and endometrial cancer tissues. Homogenates were incubated with [1,2,6,7-3H]androstenedione and NADPH at 37 degrees C for 1 h. After stopping the enzymatic reaction with ethyl acetate, [4-14C]estrone and [4-14C]estradiol-17 beta were added to the incubated sample. Estrone and estradiol were purified and identified by Bio-Rad AG1-X2 column chromatography, thin-layer chromatography and co-crystallization. Estrogen formed in the incubated sample was calculated from the 3H/14C ratio of the final crystal. The value for estrone formed from androstenedione was 52-132 fmol.h-1.g-1 wet weight. Aromatase activity in the adenomyosis tissues was higher than that in normal endometrial or myometrial tissues, but lower than that found in myometrial or endometrial tumour tissue. Furthermore, we investigated the effect of danazol, progesterone, and medroxyprogesterone acetate on adenomyosis cells in primary cultures. Aromatase activity in adenomyosis was blocked by danazol, but stimulated by progesterone and MPA. These results indicate that aromatase activity in adenomyosis may contribute to the growth of the ectopic endometrial tissue which occurs in this disease.

Real-time two-dimensional and pulsed-wave Doppler ultrasonic examinations were performed on 8 normal volunteers and 97 patients with various gynecologic disorders; the objective was to assess uterine and tumor vascularities. Each arterial blood flow velocity wave-form was classified into two types. The resistance indices of normal and abnormal flows were greater than .7 and less than .7, respectively. In normal volunteers, abnormal flows were nil. In 8 of 44 patients with benign tumors (18.2%), abnormal flows were evident and all proved to be cases of leiomyoma or adenomyosis. Doppler signals were not detected in 18 of 36 patients with cervical carcinoma (50%) and abnormal flows were noted in only 6 (16.7%). In all cases of endometrial carcinoma, ovarian carcinoma, and trophoblastic disease, typically abnormal flows were noted. Moreover, in most subjects a decrease in blood flows was observed after chemotherapy by anticancer drugs or irradiation. Therefore, Doppler ultrasound is a pertinent and noninvasive tool that can be used repeatedly for assessing the tumor vascularity in gynecologic disorders.

A case of endometrial carcinoma arising in a large adenomyomatous polyp is described in a 75-year-old woman. The malignant element appeared to be a mixed adenosquamous carcinoma that was embedded in diffuse adenomyomatous infiltration. The lesion was entirely intramural, and the surface endometrium was atrophic and not neoplastic. The absence of endometrial involvement led to a 6-year delay before hysterectomy was carried out. Pathologic study of the radically excised uterus showed evidence of metastasis to one paraaortic lymph node. Since this appears to be the first example of such an event, the English literature was reviewed for the associated findings of adenomyosis and carcinoma in an intramural setting with noninvolvement of the surface endometrium.

The sonographic appearance of the endometrium was correlated to histopathologic findings in 38 patients who underwent hysterectomy. The thickness was accurately assessed by sonography (within +/- 1 mm) in 33 of 38 patients. The hypoechoic halo which surrounds the endometrium was found to represent the inner third of the myometrium which is relatively vascular and compact. In postmenopausal patients who are not receiving hormonal replacement, an endometrium of greater than 5 mm should be considered abnormal. Several causes of abnormally thick endometrium were encountered in this study, including endometrial carcinoma, hyperplasia, adenomyosis, hematometria, mucometria, and pyometria. Sonography was found to be accurate in determining the depth of myometrial invasion in adenocarcinoma.

To evaluate the risk of transformation of atypical endometrial hyperplasia (AEH) into endometrial cancer, a group of 190 women who underwent treatment for AEH was followed up. The group included 53 women of child-bearing age, 81 in the premenopausal period, and 56 in the postmenopausal period. The most frequent clinical manifestation of AEH was metrorrhagia. The patients with mild or moderate AEH received conservative treatment, while the patients with severe AEH complicated by other gynecological diseases (uterine myoma or adenomyosis) received surgical treatment. Conservative hormonal treatment included cyclic administration of infecundin, bisecurin, hydroxyprogesterone caproate. The average duration of hormone therapy was 12 months. The 1st follow-up examination was conducted 3 months after the onset of the treatment. Of 53 patients of child-bearing age, 18 had recurrence of AEH (1 within 6 months after the initiation of the treatment, 5 within 6 months, 10 within 1-3 years, 1 within 5 years, and 1 within 9 years). Endometrial cancer was diagnosed in 2 patients (7 and 10 years after treatment of AEH). Of 81 patients in the premenopausal period, 29 developed recurrence of AEH within 3 months to 3 years of the treatment; endometrial cancer was detected in 2. Of 56 patients in the postmenopausal period, 16 developed recurrence within 3-6 months of the treatment; endometrial cancer was diagnosed in 3 patients. These findings indicate that majority of the patients with AEH can be cured by hormonal therapy, but the high risk of cancer development (3.7%) requires longterm follow-up.

Estrogen receptor (ER) and progestin receptor (PR) levels and their respective dissociation constants (Kd) were determined by titration assay and Scatchard analyses in 319 human uteri. Levels of receptors were neither age nor uterine weight dependent. ER was higher in postmenopausal patients while PR levels were lower in women under 25 years of age. ER ranged from undetectable to 560 fmol/mg cytosol protein (mcp) while PR levels were generally 10-fold greater with a mean of 791 fmol/mcp. The mean of the Kd of ER was 4.0 X 10(-10) M while that for the PR was 9.2 X 10(-10) M. Receptor levels were not correlated with their respective Kd values nor with the Kd of the other receptor; therefore ligand affinities were not receptor concentration dependent. A population of patients was identified (12.5% of the total) in which the ER levels were undetectable while their corresponding PR ranged from 38 to 2,100 fmol/mcp. This suggests the existence of a type of PR which may not require ER for its expression and is independent of the phase of the cycle. Both ER and PR content were significantly elevated in the proliferative phase of the cycle. Evaluation of results as a function of histopathological features showed no relationship between the ER and PR of patients with anovulatory bleeding versus pathology. Uteri with leiomyomas contained ER and PR at levels comparable to those of histologically normal uteri. Adenomyosis patients tended to have lower ER and higher PR levels than the normal uteri. Reference ranges have been established for these receptors in uteri as a corollary to studies of these proteins in endometrial cancer.

Among 30 cases of uterine body cancers, in eight cases (Stage IA, two cases; Stage IB, six cases) uterine adenomyosis was demonstrated microscopically. The age range was from 46 to 66 years with a median of 56. When these eight cases were compared with the 12 cases of Stage I endometrial cancer without adenomyosis, there was no difference in either menstrual history or family history, although past histories of hypertension and diabetes mellitus were found in these eight cases. The mean obesity index was 127 in eight cases and 116 in 12 cases. Seven of these eight cases were pure tubular adenocarcinoma. From the standpoint of early myometrial infiltration of the endometrial cancer, these eight cases not only provided a good model to survey early endometrial cancer but also suggested a common stimulus, such as estrogen, in both endometrial cancer and uterine adenomyosis.

The clinical records and pathologic specimens from 150 patients with endometrial carcinoma were reviewed to test the hypothesis that constitutionally predisposed patients with evidence of endogenous hyperestrinism (i.e., obesity, hypertension, diabetes, nulliparity, leiomyomata, adenomyosis) have a more benign form of carcinoma than do patients who do not fit this profile. Our results do not support this hypothesis, but do reveal certain other prognostic indicators, in addition to factors relating to the tumor itself, including stage, grade, histologic type, and extent of invasion. These indicators include: (a) age and menopausal status--women over 50 years of age, and more impressively, postmenopausal women of any age, have less favorable histology, staging, and survival; (b) race--black women have higher-grade tumors, higher-stage tumors, and poorer survival rates than white women; (c) hyperplasia--when hyperplasia is found in the biopsy, curettage, or hysterectomy specimen, the accompanying carcinoma is of a much more favorable type and extent, and survival rates are significantly better. The reasons for these correlations are not fully understood, and possible explanations are discussed. There may be two distinct patterns of endometrial carcinoma: a prognostically favorable one arising on a background of hyperplasia predominantly in premenopausal women, and a prognostically unfavorable one, occurring principally in postmenopausal women without hyperplasia. Empirically, we advise pathologists to comment on the presence or absence of hyperplasia in any specimen in which endometrial carcinoma is diagnosed.
