Clinical characteristics and pregnancy outcomes of infertile patients with endometriosis and endometrial polyps: A retrospective cohort study

ObjectiveThe aim of this study was to discuss the clinical characteristics and the prognosis of surgically diagnosed endometriosis complicated by endometrial polyps and investigate the association between pregnancy outcomes during subsequent pregnancies.Materials and methodsFrom January 2013 to December 2016, 1263 infertile patients were enrolled in the study. We identified 451 patients with endometriosis, and divided them into a polyp group (n = 204) and a non-polyp group (n = 247) based on whether or not they were associated with endometrial polyps. Postoperative clinical pregnant women (n = 82) among the polyp group were then classified into a study group and a control group composed of those undergoing a singleton pregnancy (n = 164) who delivered during the same time period. Clinical statuses and complications during pregnancy and delivery were collected from hospitals and by telephone interviews and surveys through the mail.ResultsThe prevalence rate of endometriosis infertile group was obviously higher than the non-endometriosis infertile group ([45.23%; 204/451] versus [17.12%; 139/812]). Women suffering from stage 1 to 4 endometriosis had a 42.44% (73/172), 40.69% (59/145), 55.89% (38/68) and 51.52% (34/66) occurrence rate of endometrial polyps, respectively. The frequency of endometrial polyps for stage 3 and 4 patients was obviously higher than that of stage 1 and 2 patients ([53.73%; 72/134] versus [41.64%; 132/317]). Moreover, the occurrence rate of deep infiltrating endometriosis (DIE) was 57.81% (37/64), which was obviously higher than that of ovarian endometriosis (42.42%; 98/231) and peritoneal endometriosis (44.23%; 69/156). Of the 204 women diagnosed with posterior endometrial polyps, 89 became pregnant, 7 pregnancies ended in a spontaneous abortion, and 82 successfully delivered a baby. The clinical pregnancy rate of patients in stages 1 and 2 was wholly higher than that of patients in stages 3 and 4 ([48.70%; 56/115] versus [37.71%; 26/82]). The postsurgical pregnancy status of patients suffering from peritoneal endometriosis was slightly better than those with ovarian or DIE, but differences were not statistically significant (P = 0.626). We also found that the pregnancy rate was statistically elevated in patients whose EFI scores range from 7 to 10. When compared to the control group, women with endometriosis and endometrial polyps had a higher risk of their pregnancy being complicated by placenta previa (13.41%) and cesarean delivery (59.76%).ConclusionPatients with endometriosis have a higher frequency of endometrial polyps. We found that a combined hysteroscopy and laparoscopy surgical procedure is an effective way to increase pregnancy rates. Different endometriosis stages and types in patients were associated with clinical pregnancy and spontaneous abortion rates. Women affected by both endometriosis and endometrial polyps have an independently elevated risk of placenta previa and cesarean delivery during pregnancy.

Mismatch repair protein deficiency in endometriosis: Precursor of endometriosis-associated ovarian cancer in women with lynch syndrome

ObjectiveWe aimed to elucidate the pathogenesis of ovarian cancer through the loss of mismatch repair (MMR) proteins in women with Lynch syndrome (LS) in this report.Case reportTwo women with LS underwent surgery for synchronous endometrial cancer and ovarian cancer. In both cases, immunohistochemical examination showed concomitant MMR protein deficiency in endometrial cancer, ovarian cancer, and contiguous ovarian endometriosis. In Case 1, the macroscopically normal ovary included multiple endometrioses with MSH2 and MSH6 expression, and FIGO grade 1 endometrioid carcinoma and contiguous endometriosis without MSH2 and MSH6 expression. In Case 2, all endometriotic cells contiguous with carcinoma in the lumen of the ovarian cyst showed loss of the expression of MSH2 and MSH6.ConclusionOvarian endometriosis with MMR protein deficiency may progress to endometriosis-associated ovarian cancer in women with LS. Diagnosing endometriosis in women with LS during surveillance is important.     

Benign gynecologic conditions among participants in the Breast Cancer Prevention Trial

OBJECTIVE: This study was undertaken to report on the benign gynecologic conditions occurring among women with an intact uterus at enrollment in the Breast Cancer Prevention Trial of the National Surgical Adjuvant Breast and Bowel Project. STUDY DESIGN: The incidence rates of several benign gynecologic conditions were determined and risks were compared among women receiving tamoxifen and those receiving placebo, based on risk ratios (RRs) with 95% CIs. Comparisons included stratification by menopausal status, body mass index, and history of estrogen use. RESULTS: Compared with women taking placebo, premenopausal women taking tamoxifen had a greater incidence of endometrial polyps (RR = 1.9, 95% CI = 1.55-2.41), leiomyomas (RR = 1.3, 95% CI = 1.14-1.55), endometriosis (RR = 1.9, 95% CI = 1.35-2.70), ovarian cysts (RR = 1.5, 95% CI = 1.20-1.78), and gynecologic surgical procedures, including hysterectomy (RR = 1.6, 95% CI = 1.29-1.88). Postmenopausal women taking tamoxifen also had an increased incidence of endometrial polyps (RR = 2.4, 95% CI = 1.76-3.24), leiomyomas (RR = 1.4, 95% CI = 1.04-1.80), endometriosis (RR = 1.9, 95% CI = 1.29-5.58), and gynecologic surgical procedures, including hysterectomy (RR = 2.2, 95% CI = 1.60-3.13), compared with women taking placebo. All women taking tamoxifen also had an increased incidence of simple endometrial hyperplasia without atypia (overall RR = 2.06, 95% CI = 1.64-2.60) compared with those taking placebo. CONCLUSIONS: Our results strongly support the estrogen agonist role of tamoxifen as the causative factor for the increased risk of endometrial polyps, leiomyomas, endometriosis, and endometrial hyperplasia among women taking this agent.     

Hysteroscopic evaluation of endometrial polyps.

OBJECTIVE: To establish the validity of hysteroscopy for predicting cancer in endometrial polyps based on their number, size and hysteroscopic appearance. METHOD: Retrospective observational study of 653 women diagnosed hysteroscopically as having endometrial polyps. After outpatient or surgical hysteroscopic resection or resection following hysterectomy, the diagnosis was confirmed by histological examination. The incidence of cancer in women who had polyps was determined in the light of menopausal status, symptoms, size, number and appearance of the polyps. RESULT: Carcinoma was found in only 3.9% of the women who consulted for menopausal metrorrhagia and were diagnosed as having a polyp. Hysteroscopy had a sensitivity of 36% and a specificity of 98% for a diagnosis of cancerous polyp or atypical hyperplasia. CONCLUSION: The appearance and number of endometrial polyps seen by hysteroscopy may be useful in predicting cancer in the polyps, although resection and histological examination will still be necessary to confirm the diagnosis.     

Role of Ovarian Suspension in Preventing Postsurgical Ovarian Adhesions in Patients with Stage III-IV Pelvic Endometriosis: A Systematic Review

Endometriosis is a benign complex gynecologic condition with high morbidity that affects women of reproductive age. Pelvic adhesion formation represents a serious clinical challenge in the management of patients with endometriosis. Several interventions aimed at reducing postoperative ovarian adhesion formation have been proposed in recent years. Here we summarize the published evidence on the efficacy of ovarian suspension in preventing postoperative ovarian adhesion formation in women undergoing laparoscopic surgery for stage III-IV endometriosis. The research was conducted using electronic databases. A review of the abstracts of all references retrieved from the search was conducted. Selection criteria for the systematic review included all randomized controlled trials (RCTs) and nonrandomized studies (NRSs) of premenopausal women diagnosed with stage III-IV pelvic endometriosis who underwent ovarian suspension or no ovarian suspension (control group). The RCTs were eligible for meta-analysis. Eight studies, 2 RCTs and 6 NRSs, were included in the systematic review. In all 8 studies, ovarian suspension was performed during surgery for stage III-IV endometriosis. The site of the suspension was the anterior abdominal wall in 76.8% of the cases. Five studies reported the use of polypropylene as suture for the suspension. Removal of the suspension suture in the postoperative period was reported in 6 studies. Pooled data from a meta-analysis of the RCTs show that women who underwent ovarian suspension had a significantly lower incidence of postoperative adhesion formation, particularly of moderate to severe adhesions. Ovarian suspension may reduce the rate and severity of postoperative adhesions formation in women undergoing laparoscopy for the treatment of stage III-IV endometriosis; however, RCTs with larger sample sizes are needed.     

Coexisting ovarian malignancy in young women with endometrial cancer

OBJECTIVE: In premenopausal women with endometrial cancer, ovarian preservation may be a consideration. Our objective was to examine the occurrence of coexisting ovarian malignancy and to identify predictors of adnexal involvement. METHODS: With institutional review board approval, a retrospective chart review was conducted of young women with endometrial cancer identified at 4 affiliated institutions from 1996 to 2004. RESULTS: Among 102 young women (aged 24-45 years) who underwent hysterectomy for endometrial cancer, 26 (25%) were found to have coexisting epithelial ovarian tumors: 23 were classified as synchronous primaries, and 3 as metastases. Ovarian cancer histology was endometrioid in 92% of cases. Among the 26 cases of coexisting ovarian involvement, 12 (46%) had grade 1 endometrial cancer on preoperative biopsy, 4 (15%) had normal preoperative imaging of the adnexa, and 4 (15%) had benign-appearing ovaries at the time of intraoperative assessment. On final pathology, 18 of 26 cases (69%) occurred in patients with grade 1 endometrial cancers, and 15 (58%) occurred with inner myometrial invasion. Our study further highlights the risk of conservative management with 1 case of ovarian cancer diagnosed 9 months after hysterectomy with ovarian conservation for a stage IA, grade 1 endometrial cancer and a case of advanced endometrial cancer metastatic to the ovaries developing 3 years after successful resolution of a grade 1 endometrial cancer treated with megestrol acetate (Megace). CONCLUSION: Careful preoperative and intraoperative assessment of the adnexa is mandatory in young women with endometrial cancer. Those who desire ovarian preservation should be counseled regarding the high rate of coexisting ovarian malignancy.     

Outcomes of endometrial-polyp treatment with hysteroscopy in operating room

To assess the results of using a resectoscope in the hysteroscopic resection of endometrial polyps that were previously diagnosed by office hysteroscopy and to demonstrate the necessity of extraction for histological study. A prospective long-term follow-up study (level of evidence II-2). University Hospital. 303 women presenting a hysteroscopic image of an endometrial polyp. Interventions: Office hysteroscopy, hysteroscopic resection of polyps by means of a resectoscope and an anatomopathological study of the polyps. Statistical analysis was performed. 303 diagnosed endometrial polyp formations were resected by means of hysteroscopy during surgery. In all cases, biopsies of the uterine cavity or of the polyp were negative. Resection of the polyps with hysteroscopy in the operating room using a resectoscope proved to be a safe technique. The anatomopathological study of the polyps showed hyperplasia with atypias in 10 cases (3.3%) and endometrial cancer in 9 women (3.0%). Our study data suggest that endometrial polyps should be resected because they may harbor malignant or premalignant lesions. Hysteroscopic surgery is recommended for its simplicity and scant complications.     

Ovarian endometriosis associated with ovarian carcinoma: a clinicopathological and immunohistochemical study

OBJECTIVE: The purpose of this study was to demonstrate the incidence, the histopathological characteristics, and the proliferation activity of endometriosis and atypical endometriosis associated with ovarian carcinoma. METHODS: Microscopic slides of primary lesions from 127 patients with primary ovarian carcinoma were reviewed. The presence or absence of endometriosis and the transitions from typical endometriosis to atypical endometriosis and from atypical endometriosis to carcinoma were also histologically evaluated. Ki-67 immunoreactivity of typical and atypical endometriosis and carcinoma was examined. In addition, endometrial metaplasias were also evaluated. RESULTS: Of the 127 patients, 37 had endometriosis: 70% (30/43) had clear cell adenocarcinoma, 43% (3/7) had endometrioid adenocarcinoma, 7% (4/60) had serous adenocarcinoma, and none (0/17) had mucinous adenocarcinoma. Thirty-three cases showed typical endometriosis and 29 cases had atypical endometriosis (25 cases had both). Tufting and the stratification of the lining epithelium were observed in 25 and 23 cases, respectively. The transition from typical endometriosis to atypical endometriosis was observed in 22 cases, and the transition from atypical endometriosis to carcinoma, in 23 cases. Only one case showed a direct transition from typical endometriosis to carcinoma. The mean Ki-67 indices were as follows: ovarian carcinoma, 23.1; atypical endometriosis, 9.9; typical endometriosis, 2.7. In 18 cases with metaplasia in endometriosis, eosinophilic metaplasia and ciliated metaplasia were the most common types. Five cases had two types of metaplasia. CONCLUSIONS: Ovarian carcinomas, especially clear cell and endometrioid adenocarcinomas, are highly associated with endometriosis. Atypical endometriosis shows proliferation activity intermediate to those of typical endometriosis and ovarian carcinoma, suggesting it is a precancerous status.     

Annual surveillance by CA125 and transvaginal ultrasound for ovarian cancer in both high-risk and population risk women is ineffective

Objective  To assess the efficacy of annual CA125 and transvaginal ultrasound (TVU) scan as surveillance for ovarian cancer.
Design  Retrospective audit.
Setting  NHS Trust.
Population  Three hundred and forty-one asymptomatic women enrolled for ovarian cancer screening: 179 were in a high-risk group (>10% lifetime risk of developing ovarian cancer), 77 in a moderate risk group (4–10% lifetime risk of developing ovarian cancer) and 71 in a near population risk group (<4% lifetime risk).
Methods  Retrospective audit of case records, laboratory CA125 results, radiology reports, histology records and local cancer registry data.
Main outcome measures  Ovarian cancers occurring in study population. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of TVU, and CA125 as a screening tool for ovarian cancer.
Results  Four ovarian cancers and one endometrial cancer occurred. One ovarian cancer was detected at surveillance, three occurred in women who presented symptomatically between screenings. Thirty women underwent exploratory surgery because of abnormal findings at surveillance. Two women had cancer (PPV = 6.7%); one had ovarian cancer and the other endometrial cancer. Twenty-eight women (93.3%) had no malignancy. Sensitivity, specificity, PPV and NPV for TVU in the whole cohort were 33.3, 85.8, 0.6 and 99.8%, respectively. For high-risk individuals, the figures for TVU were 33.3, 84.5, 1.1 and 99.6, respectively. Combining both modalities for the whole cohort, the sensitivity, specificity, PPV and NPV were 66.7, 82.9, 1.5 and 99.8% and 50.0, 82.8, 1.3 and 99.7%, respectively, for the high-risk group alone.
Conclusions  Ovarian screening by annual TVU and CA125 is inefficient at detecting early-stage ovarian cancers.     

Case report of malignant endometrial polyps

The aims of this retrospective review were to determine the frequency of malignant endometrial polyps diagnosed with ambulatory hysteroscopy in the Obstetrics/ Gynaecology Department of HDE, Lisbon, between January 2001 and December 2005 and to characterize these cases according to risk factors, sonographic and endoscopic findings tumoral histology, and tumor stage. We found seven cases of malignant endometrial polyps in a total of 1333 polyps initially diagnosed: an incidence rate of 0. 53%. These seven patients had a mean age of 68 years (55–82 years), and all were postmenopausal, with five having one risk factor each for endometrial cancer. Metrorrhagia was present in six of the seven patients (85.7%). Ultrasonography was abnormal in all seven patients, with a mean endometrial thickness of 26 mm (range: 12–44 mm). The hysteroscopy images suggested malignancy in all cases. All except one patient had a single polyp. The polyps had volumes between 1.5 and 3 cm; two were removed completely and five were biopsed. The histological subtype was: mixed endometrioid/serous papillary or clear cell (2), adenocarcinoma with squamous differentiation (2), carcinosarcoma (2), and clear cell carcinoma (1). Malignancy inside polyps is rare, but diagnostic hysteroscopy with visual guided biopsies can identify these cases in the earlier stages. The risk factors are not different from those of other endometrial carcinomas, but the histological subtype seems to point to more aggressive cancers.     

Transvaginal ultrasound and diagnostic hysteroscopy as a predictor of endometrial polyps: risk factors for premalignancy and malignancy

The aim of this study is to assess accuracy of transvaginal ultrasound (TVUS) and diagnostic hysteroscopy in diagnosing endometrial polyps and to determine premalignancy and malignancy rates in asymptomatic women. The study was designed to retrospectively analyze 438 women who underwent operative hysteroscopy in a day-care unit when endometrial polyp was suspected after TVUS and diagnostic hysteroscopy. Multivariate logistic regression modeling showed effects of age, previous breast cancer with tamoxifen treatment, and menopause with or without bleeding on pathologic results. The results indicate that positive predictive value of TVUS with diagnostic hysteroscopy was 79.9%. Premalignancy or malignancy occurred in 3.2% and was significantly related to menopause with abnormal bleeding (P < 0.001), which carried a 20-fold higher risk of pathology than any other group. Age was also a risk factor. It was concluded that TVUS with diagnostic hysteroscopy reliably evaluates endometrial polyps. The low incidence of endometrial tumors in asymptomatic (especially premenopausal) women suggests that their operative evaluation may not be cost effective. Larger studies are needed to support this tentative conclusion.     

Endometrial polyps in obese asymptomatic pre and postmenopausal patients with breast cancer: Is screening necessary?

Objective

To evaluate the prevalence of endometrial polyps in obese asymptomatic pre and postmenopausal patients with breast cancer and to know if a baseline pretamoxifen endometrial assessment should be taken into consideration in these women at high risk.

Methods

A cross-sectional study was carried out with 201 women with breast cancer. A diagnostic hysteroscopy was performed in all women. All formations suspected as polyps were removed. The prevalence of endometrial polyps was analyzed in all patients (n = 182) and in premenopausal (n = 49) and postmenopausal (n = 118) women with estrogen receptor (ER) positive breast cancer (BC) according to their body mass index (BMI) and other risk factors.

Results

Hysteroscopic evaluation was possible in 182 cases (90.5%). Of the total of women, 160 (87.9%) were ER(+)BC patients, 133 (73.1%) postmenopausal women and 41.5% were obese (BMI ≥ 30 kg/m²). Endometrial polyps were found in 52 cases (28.5%) (3 cases of simple hyperplasia harbored within a polyp). In premenopausal patients with ER(+)BC, there were no statistical differences in endometrial polyps according to their BMI (22.3% in non-obese women vs 31.7% in obese) while in all patients (26.4% in non-obese vs 44.0% in obese) and in postmenopausal women with ER(+)BC (25.9% in non-obese vs 48.6% in obese) there were statistical differences. In all women the relative risk (RR) of endometrial polyps in obese patients was 2.24 (1.01–4.83), in obese postmenopausal women with ER(+)BC was 2.75 (1.01–7.40) and in obese premenopausal patients with ER(+)BC was 1.42 (0.80–3.29).

Conclusions

Asymptomatic women with breast cancer have a high prevalence of baseline subclinical endometrial polyps and it is very high in obese postmenopausal patients with estrogen receptor positive breast cancer. Therefore, there may be a future role for baseline pretamoxifen screening of some sort for the obese asymptomatic postmenopausal patient, especially if they are elderly and ER positive.     

Adenomyosis and junctional zone changes in patients with endometriosis

Objectives

To evaluate image findings in the junctional zone (JZ) in patients with endometriosis and correlate with image findings of adenomyosis. To attempt a correlation of the degree of adenomyotic infiltration with the degree of infiltration and stage of endometriosis.

Study design

Magnetic resonance imaging (MRI) of the uterus was performed in 153 women with suspected deeply infiltrating endometriosis and planned surgery, and in a reference group of 129 women without endometriosis, verified during hysterectomy. Changes in the JZ and endometriosis in the pelvis were described in detail. Diagnosis of adenomyosis at MRI was based on optimal criteria derived from the hysterectomy control group. The stage of endometriosis (AFS stage) was determined during surgery.

Results

In the group of women with endometriosis 34.6% had adenomyosis compared with 19.4% in the reference group (p < 0.05). More women with endometriosis (39.9%) had an irregular JZ compared to 22.5% in the reference group (p < 0.01). Among women with severe endometriosis (AFS stage IV) 42.8% had adenomyosis compared to 29.4% in the women with other stages of endometriosis (AFS stages I + II + III) (p = 0.10). More women with severe endometriosis (AFS stage IV) had deeper wall invasion of adenomyosis (p > 0.05) but the presence of deep infiltrative rectovaginal endometriosis and the size of infiltration were not correlated to adenomyosis or depth of infiltration of adenomyosis.

Conclusions

In a group of young women with severe symptomatic endometriosis and planned surgery a systematic evaluation of the JZ revealed that one third had uterine adenomyosis, but the invasive potential of endometrial cells in the uterus and in the peritoneum corresponded only to a limited degree.     

High frequency of endometrial polyps in endometriosis

STUDY OBJECTIVE: To evaluate the effectiveness of hysteroscopy and the frequency of endometrial polyps in women with endometriosis. DESIGN: Retrospective clinical study (Canadian Task Force classification II-2). SETTING: Infertility unit at a university-affiliated hospital. PATIENTS: One hundred eighty-three infertile women, 92 with endometriosis and 91 controls without the disease. INTERVENTION: Laparoscopy and scoring of endometriosis according to the American Fertility Society classification, and confirmation of endometrial polyps by pathologic examination. MEASUREMENTS AND MAIN RESULTS: There was no significant difference between groups with regard to age, mean duration of infertility, and frequency of primary or secondary infertility. Endometrial polyps were found in 43 women (46.7%) with endometriosis and in 15 controls (16.5%, p = 0.0000). Their frequency did not differ significantly according to stage of endometriosis. CONCLUSIONS: We strongly recommend hysteroscopy if endometriosis is detected in a woman undergoing evaluation for infertility, even if hysterosalpingography and transvaginal ultrasonography do not suggest endometrial polyps.     

Ovarian cancer risk associated with varying causes of infertility

OBJECTIVE: To evaluate the risk of ovarian cancer as related to underlying causes of infertility. DESIGN: Retrospective observational cohort study. SETTING: Five large reproductive endocrinology practices. PATIENT(S): A total of 12,193 women evaluated for infertility between 1965 and 1988. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Ovarian cancer ascertained through 1999. RESULT(S): With 45 identified ovarian cancers, this cohort of infertility patients demonstrated a significantly higher rate of ovarian cancer than the general female population (standardized incidence ratio [SIR] = 1.98; 95% confidence interval [CI], 1.4-2.6). The risk was higher for patients with primary infertility (SIR = 2.73) than for those with secondary infertility (SIR = 1.44), and it was particularly high for patients who never subsequently conceived (SIR = 3.33). Women with endometriosis had the highest risk (SIR = 2.48; 95% CI, 1.3-4.2), with a further elevated risk among those with primary infertility (4.19, 2.0-7.7). Comparisons among the infertile women, which allowed calculation of rate ratios (RRs) after adjustment for multiple factors, also showed links with endometriosis. Compared with women with secondary infertility without endometriosis, patients with primary infertility and endometriosis had a RR of 2.72 (95% CI, 1.1-6.7). CONCLUSION(S): Determination of ovarian cancer risk should take into account the type of infertility (primary vs. secondary) and underlying causes. Further study of endometriosis may provide insights into ovarian carcinogenesis.

Risk of developing ovarian cancer among women with ovarian endometrioma: a cohort study in Shizuoka, Japan

Although some studies have indicated that endometriosis may increase the risk of developing ovarian cancer, there are no data from epidemiologic studies in Japan. We prospectively analyzed all cases of ovarian endometrioma enrolled in the prefecture-wide Shizuoka Cohort Study on Endometriosis and Ovarian Cancer Programme, which was initiated in 1985. To evaluate the risk of ovarian cancer by time periods subsequent to ovarian endometrioma diagnosis, a cohort of 6,398 women with a clinically documented ovarian endometrioma in Shizuoka between 1985 and 1995 was identified from the Shizuoka Cancer Registry (SCR), with follow-up through 2002. Ovarian cancer incidence among cohort members was ascertained by linkage to the SCR using a unique person-identification number. Standardized incidence ratios (SIR) and their 95% confidence intervals (CI) were computed by a use of prefecture-wide rates of ovarian cancer, adjusted for age and calendar year. During follow-up of up to 17 years of the ovarian endometrioma cohort, 46 incident ovarian cancers were identified, yielding that the ovarian cancer risk was elevated significantly among patients with ovarian endometrioma (SIR = 8.95, 95% CI = 4.12-15.3). The SIR did not increase with increasing follow-up duration. The risk increased with increasing age at ovarian endometrioma diagnosis, with a SIR equal to 13.2 (95% CI = 6.90-20.9) in women above 50 years of age. Our findings for the first time support the hypothesis that ovarian endometrioma increases the subsequent risk of developing ovarian cancer in Shizuoka, Japan.     

Specific hysteroscopic findings can efficiently distinguish the differences between malignant and benign endometrial polyps

ObjectiveTo evaluate differences in hysteroscopic findings between benign endometrial polyps and endometrial cancer.Materials and methodsFrom January 2012 to December 2016, we extracted 179 cases with endometrial polyps from 3066 women who underwent hysteroscopy followed by dilatation and curettage or transcervical resection, with 154 and 25 cases of benign and malignant endometrial polyps, respectively. Clinical characteristics, histopathological and hysteroscopic findings of the women were evaluated retrospectively.ResultsThe hysteroscopic findings of malignant polyps were hyper-vascular (72%, 18/25), ulcerative (64%, 16/25) and polyps with irregular surfaces (24%, 6/25). In contrast, pedunculate small growths with smooth surfaces were usually seen in the benign endometrial polyps (38.3%, 59/154). Hyper-vascular (OR: 142.6, 95% CI: 25.98–783.4) and polyps with irregular surfaces (OR: 12.02, 95% CI: 1.765–81.83) in hysteroscopic findings were significant strong predictors of endometrial polyps with endometrial cancer. Hysteroscopic findings of ulcerative changes were most strongly associated with a diagnosis of malignant polyps, with sensitivity, specificity, negative (NPV) and positive (PPV) predictive values of 64.0%, 100%, 94.5%, and 100%, respectively.ConclusionWomen with hysteroscopic findings of endometrial polyps with hyper-vascular, ulcerative, and polyps with irregular surfaces had a high likelihood of endometrial cancer. A target biopsy of the polyps with these specific appearances should be performed to exclude malignant lesions.
