卵巢腺纤维瘤及囊性腺纤维瘤的超声特点   总被引:1,自引:0,他引:1  
目的探讨卵巢腺纤维瘤及囊性腺纤维瘤的术前超声特征,以便帮助临床提高术前诊断准确性。方法对北京大学人民医院妇科自2004年8月~2006年8月收治并经手术病理证实的卵巢腺纤维瘤或囊性腺纤维瘤患者24例术前超声结果进行回顾性分析,并选取同期良性浆液性囊腺瘤39例及交界性囊腺瘤49例作对照。结果24例卵巢腺纤维瘤或囊性腺纤维瘤中,良性18例,交界性5例,癌变1例。肿瘤单侧22例(91.67%),15例(62.50%)为单房,平均直径7.40cm。10/18例(55.56%)良性浆液性腺纤维瘤或囊性腺纤维瘤内出现乳头或实性部分,与交界性囊腺瘤相比差异具有显著性(P=0.002)。实性区仅1/10(10%)例可检测到血流信号,与交界性囊腺瘤相比差异具有显著性(P=0.003)。结论卵巢腺纤维瘤及囊性腺纤维瘤单侧多见,单房多见,半数以上可见囊内乳头或肿瘤囊实性,但乳头或实性区一般少血流,且血流阻力指数一般〉0.50。一旦乳头或实性区血流信号丰富,或者阻力指数〈0.50,应警惕肿瘤交界性或癌变。  相似文献

OBJECTIVE: Our purpose was to evaluate the risk of malignancy in surgically removed ovarian cysts that were characterized before the operation as unilocular according to transvaginal ultrasonography. STUDY DESIGN: This prospective analysis included 927 premenopausal women and 377 postmenopausal women operated on at 2 European university hospitals between January 1992 and December 1997. On the basis of ultrasonographic findings the cysts were characterized either as echo-free, without solid parts or papillary formations (group 1), or as having echogenic cyst content, with solid parts or papillary formations (group 2). Ultrasonographic and macroscopic appearances of the cysts were compared with histopathologic diagnosis. RESULTS: In group 1, in premenopausal women 3 of 413 cysts (0.73%) proved to be borderline or malignant, and in postmenopausal women 4 of 247 cysts (1.6%) proved to be borderline or malignant. The figures for cysts in group 2 were 11 of 514 cysts (2.1%) and 13 of 130 cysts (10.0%), respectively. It was not possible to differentiate by transvaginal ultrasonography between benign, borderline, and malignant cysts when solid parts or papillary formations were visualized. CONCLUSIONS: This study confirmed that the risk of malignancy associated with unilocular echo-free cysts (group 1) was low. Serial ultrasonographic follow-up should therefore be the standard procedure with unilocular echo-free cysts <50 mm in diameter. In cysts with a mean diameter of >50 mm, papillary formations or solid parts may be missed by transvaginal ultrasonography. The risk for malignancy in cysts containing papillary formations or solid parts (group 2) was 3 to 6 times higher than that in unilocular echo-free cysts.  相似文献

Objective.Our objective was to improve the preoperative diagnosis of ovarian malignancy using a multivariate logistic regression analysis on the basis of demographic, serologic, gray-scale morphological, and Doppler variables.Methods.One hundred seventy-one patients with ovarian tumors (120 benign, 51 malignant including 9 tumors of low malignant potential) were studied with transvaginal B-mode, color, and pulsed Doppler ultrasonography before surgery. Based on the gray-scale ultrasound imaging, each tumor was classified as a unilocular cyst, multilocular cyst, unilocular cyst with solid parts, multilocular cyst with solid parts, or solid tumor. Intratumoral blood flow velocity waveforms were recorded on all tumors except unilocular cyst and were evaluated for resistance index (RI) and peak systolic velocity (PSV). Serum CA 125 levels were also measured.Results.Twenty tumors were unilocular cysts and were all benign. Seventy tumors including all unilocular cysts which showed no flows were all benign. The remaining 101 tumors (50 benign, 51 malignant including 9 tumors of low malignant potential) presented intratumoral blood flows. Univariate and multivariate logistic regression analyses were conducted to identify variables predictive of ovarian malignancy in these 101 tumors. The variables included age, menstrual state, serum CA 125 levels, B-mode classification, RI, and PSV. In univariate analysis, menopause, the positivity of CA 125 (≥35 U/ml), and PSV larger than or equal to 10.4 cm/s were found to be significantly associated with malignant tumors. The PSV value of 10.4 cm/s was the median in benign tumors. Multivariate analysis showed that serum CA 125 levels (≥35 U/ml) (P= 0.002) and PSV (≥10.4 cm/s) (P< 0.001) were to be independent predictors of malignancy.Conclusion.These results suggest that intratumoral PSV is the strongest means of differentiating benign from malignant ovarian tumors with suspicious gray-scale ultrasonographic findings.  相似文献

To clarify the tumor behavior in borderline ovarian tumors, we examined the characteristics of neovascularization in these tumors by using a transvaginal color Doppler ultrasound (TV-CDU). Twelve patients with borderline ovarian tumors were preoperatively evaluated for the characteristics of intratumoral blood flow by TV-CDU, using both the resistance index (RI) and pulsatility index (PI). As a control group, 100 patients with benign ovarian tumors and 31 patients with malignant ovarian tumors were also examined by TV-CDU. An intratumoral blood flow was significantly detected in both borderline (91.6%; 11/12) and malignant ovarian tumors (90.3%; 28/31), but not in benign ovarian tumors (53%; 53/100) (P< 0.01). In addition, both the mean RI and mean PI values were significantly lower in the borderline (RI; 0.45, PI; 0.67) and malignant ovarian tumors (RI; 0.39, PI; 0.58) than those in the benign ovarian tumors (RI; 0.61, PI; 1.05) (P< 0.01). In mucinous tumors, the borderline tumors showed a significantly high intratumoral vascularity (P< 0.01) and both borderline and malignant tumors significantly demonstrated a low-resistance blood flow (P< 0.01), in comparison to those of the benign tumors. Mucinous borderline tumors of the intestinal type also tended to have a lower RI as well as a lower PI value than müllerian type. Regarding neovascularization as represented by intratumoral blood flow characteristics, this study thus suggests that a close relationship exists in the tumor behavior between borderline and malignant ovarian tumors, especially in mucinous epithelial tumors.  相似文献

Ovarian mucinous tumors stem from ovarian surface epithelium and are divided into benign, borderline and malignant. It is difficult to differentiate borderline and malignant mucinous tumors. Thirty-eight cases of ovarian mucinous tumors which were diagnosed at the Pathology Department of Dicle University Medical Faculty were reviewed. Of these, 18 (47.3%), six (15.7%) and 14 (36.8%) were benign, borderline and malignant, respectively. The patients' ages ranged from 18 to 67 (average 44.5) years. Bilaterality was detected in 1/18 (5.5%), 0/6 and 4/14 (28.5%) of benign, borderline and malignant mucinous tumors, respectively. Mean tumor size was 26.4 cm. Microscopically, there was no stratification in the benign tumors. The borderline tumors had papillary infoldings and 2-3 layers of atypical epithelial cells but no invasion of the stroma. Malignant tumors had four or more layers of atypical epithelial cells and stromal invasion.  相似文献

CA 125 measurement and ultrasonography in borderline tumors of the ovary   总被引:15,自引:0,他引:15  
OBJECTIVES: Our goal was to perform an analysis of ultrasonographic characteristics and CA 125 levels in ovarian tumors of borderline malignancy. STUDY DESIGN: We performed a retrospective analysis of CA 125 levels and ultrasonographic parameters in 91 patients with borderline tumors. RESULTS: Serous tumors of borderline malignancy were associated with elevated CA 125 levels in 75% of patients before surgery (mean, 156 IU/mL) compared with 30% of mucinous tumors (mean, 28 IU/mL; P =.004). CA 125 was elevated in 35% of stage IA serous tumors (mean, 67 IU/mL) compared with 89% of tumors with spread beyond the ovary (mean, 259 IU/mL; P =.001). Mucinous tumors tended to be bigger (13.1 +/- 7 cm) on ultrasonography than serous tumors (9.3 +/- 6.2 cm, P =.016). Mucinous tumors were multilocular in half the patients and contained papillations in 40% of the patients. Serous tumors were multilocular in 30% of the patients but presented with solid or papillary patterns in 78% of the patients (P =.001). A resistance index of <0.4 was found in 36% of mucinous tumors and half the cases of serous tumors. In 13% of patients, ultrasonographic characteristics were compatible with a simple cyst only, including 1 patient with microinvasion and 1 patient with stage IIIB disease. Sensitivity of gray-scale ultrasonography was 87%, that of CA 125 measurement was 62%, and that of flow was 55%. At least 1 diagnostic test result was abnormal in 93% of patients, 2 were abnormal in 69% of patients, and all 3 were abnormal in 21% of patients. CONCLUSIONS: A high proportion of borderline tumors of the ovary, particularly of the serous type, were associated with elevated CA 125 levels and abnormal ultrasonographic characteristics, although some tumors presented as simple cysts.  相似文献

Ultrasound characteristics of different types of adnexal malignancies   总被引:5,自引:0,他引:5  
OBJECTIVE: To describe ultrasound characteristics of adnexal malignancies, i.e., borderline ovarian tumors, primary invasive ovarian epithelial cancer stage 1, primary invasive ovarian epithelial cancer stages 2-4, rare types of malignancy, and metastatic tumors. METHODS: In a prospective international study involving nine European ultrasound centers, 1,066 women with a pelvic mass judged to be of adnexal origin underwent transvaginal gray scale and color Doppler ultrasound examination by a skilled examiner before surgery. A standardized examination technique and predefined definitions of ultrasound characteristics were used. RESULTS: Of 1,066 masses, 266 were malignant and are included: 55 ovarian borderline tumors, 144 primary invasive epithelial ovarian cancers (42 stage 1, 102 stages 2-4), 25 rare malignancies, and 42 metastatic tumors. Most (56%) metastatic tumors and most (60%) rare types of tumor were solid and richly vascularized at color Doppler ultrasound examination (on a scale ranging from 1 to 4, color score based on subjective evaluation was 3 or 4 in 88% and 86%, respectively). Borderline ovarian tumors and stage 1 primary invasive ovarian epithelial cancers differed from stages 2-4 primary invasive ovarian epithelial cancers: they were larger (median volume 375 ml and 695 ml vs. 209 ml; P = 0.0213 and 0.0001), a larger proportion contained papillary projections (64% and 67% vs. 41%; P = 0.0072 and 0.0054), they were more often multilocular cysts without solid components (18% and 14% vs. 2%; P < 0.0017 and 0.0204), but they were less often purely solid (5% and 7% vs. 38%; P 相似文献

Summary In order to determine whether sonography could differentiate between benign and malignant ovarian neoplasms a retrospective analysis of preoperative ultrasound examination was made. The ultrasound images were evaluated for internal consistency, presence of septae, presence of solid nodules, papillary projections and tumor borders. Evidence of ascites and omental involvement were also assessed. Our study showed that benign ovarian serous tumors had a similar appearance to low grade malignant serous tumors, and were undistinguishable from the borderline serous carcinoma. The poorly differentiated serous adenocarcinoma was characterized by the presence of thick papillary projections rather than echogenicity. However, benign or malignant mucinous tumors gave the same pattern. Loss of tumor wall definition, ascites and omental involvement may signal malignancy. The dermoid tumor had a characteristic sonographic appearance.  相似文献

Ultrasound is now frequently used for evaluation of pathological findings discovered on gynecological examination and for puncture of ovarian cysts. Although the new, high-frequency vaginal transducers have a very high resolution, only macroscopically visible structures of the tumors can be imaged. For this reason, it seemed important to classify ovarian tumors according to their macroscopic appearance and then relate this to whether the tumor was benign, borderline, or malignant. Such a classification has not been performed before. Medical records from women operated upon due to pelvic tumors over a period of 11 years were scrutinized. There were 1017 women included in the study. Among those tumors characterized as unilocular cysts 0.3% (1/296) was malignant; this tumor had macroscopically visible papillary vegetations on the inside of the cyst wall. This cyst was found in a woman 60 years old. Sixty percent (178/296) of the women who had a unilocular cyst were over the age of 40. Two percent (4/203) of the unilocular solid tumors were classified as malignant. The malignancy rates for multilocular cysts was 8% (20/229), multilocular solid tumors 36% (147/209), and solid tumors 39% (31/80). Papillary vegetation on the cyst wall was the structure that was most frequent in malignant tumors. Neither the thickness of the cyst wall nor the thickness of septa inside the tumor seemed to correlate with malignancy. Among the simple ovarian cysts, 65 had a diameter over 10 cm but none of them was malignant. The one that was malignant had a diameter of approximately 5 cm. In conclusion, unilocular ovarian cyst seems to carry a very slight chance of malignancy even in women over the age of 40. Papillary vegetation on the cyst wall, a structure that can be seen by ultrasound, seems to be a serious sign.  相似文献
