Bilateral tubal ectopic pregnancy following induction ovulation can be missed in emergent ultrasonography: Case report.

INTRODUCTION: Bilateral tubal ectopic pregnancy (BTP) is a rare and potentially life-threatening condition that is, often challenging to diagnose preoperatively. PRESENTATION OF CASE: We present a case of BTP in a 25-year-old primigravid woman with a history of infertility due to polycystic ovarian syndrome. She was receiving letrozole when she presented with severe abdominal pain and vaginal bleeding. Initial evaluation revealed a ruptured ectopic pregnancy in the right fallopian tube, prompting an emergency laparotomy. During surgery, a second intact ectopic mass was discovered in the left fallopian tube, highlighting the diagnostic complexity of BTP. Management involved a salpingectomy on the right side and salpingostomy on the left to preserve fertility. DISCUSSION: This case underscores the importance of considering BTP in the differential diagnosis of ectopic pregnancies and the necessity for thorough preoperative imaging studies, namely ultrasonography and surgical exploration, to prevent missed diagnoses. CONCLUSION: BTP is a rare and challenging clinical entity that requires a comprehensive approach to diagnosis and management. Early recognition, prompt intervention, and close surveillance are essential to mitigate the risk of maternal morbidity and mortality associated with this condition.

Early diagnosis of impending rupture uterus during U/S: A case report.

INTRODUCTION AND IMPORTANCE: Uterine rupture is a rare condition that typically occurs in a scarred uterus and can happen during late pregnancy, labor, or the early postpartum period. Since most cases are seen in patients with a history of cesarean surgery, the anterior lower uterine segment is the most affected area. Most patients present with acute symptoms that compromise the fetus and the mother in a life-threatening manner. CASE PRESENTATION: We present a case of uterine rupture with subacute symptoms occurring in the second trimester, which is extremely rare. The patient was a stable second-trimester multiparous woman with chronic abdominal pain, but without any signs of peritoneal bleeding or instability. No history of previous cesarean section was present, and she had recently undergone a non-complicated hysteroscopic polypectomy. Transabdominal and transvaginal ultrasounds were performed, revealing a significant full-thickness myometrial defect in the posterior uterine lower segment. This defect allowed the amniotic sac to protrude into the posterior cul-de-sac. No abdominopelvic hematoma was detected. These findings were confirmed in an urgent MRI, and the patient underwent a laparotomy during which a significant full-thickness defect was discovered at the posterior of the uterus. As it was impossible to continue the pregnancy, the fetus was surgically removed and then prepared using multiple layers. CLINICAL DISCUSSION: The difference between our case and the previously reported one is in the aspect of gradual stable presentation and lacks of vaginal bleeding. CONCLUSION: Previous hysteroscopy carries a risk for future pregnancy complications, such as uterine rupture.

Hypofractionated versus standard chemoradiotherapy in the definitive treatment of uterine cervix cancer: interim results of a randomized controlled clinical trial.

PURPOSE: Concurrent chemoradiation has been the mainstay of treatment for cervix cancer. We aimed to evaluate the non-inferiority of hypofractionated chemoradiation. METHODS: This study was designed as a phase 2, 1:1 randomized, investigator-blinded, controlled, non-inferiority trial and we report the interim results after 50% accrual. Cervical cancer patients with FIGO stages IIA-IIIC were recruited from April 2021 to September 2022. The intervention consisted of 40 Gy of 3D-conformal radiation therapy (RT) in 15 fractions over 3 weeks. In the control group, patients received standard chemoradiation of 45 Gy in 25 fractions over 5 weeks. Both groups received concurrent weekly cisplatin (40 mg/m2). Intravaginal brachytherapy of 28 Gy in 4 weekly fractions was delivered starting 1 week after the end of chemoradiation. The primary outcome was complete clinical response(CCR) at 3 months. Secondary outcomes included acute gastrointestinal (GI), genitourinary(GU), skin, and hematologic toxicities. A p value less than 0.05 was considered significant for analyses. RESULTS: 59 patients were randomized; 30 in the control group and 29 in the intervention group. 20/30 (66.7%) of the patients in the control group and 19/29 (65.5%) in the intervention group achieved a CCR (absolute difference of 0.011, 95% CI - 0.23 to 0.25, p value: 0.13). There was a significantly higher rate of acute grade ≥ 3 GI toxicity in the intervention group (27.6%) compared with the control group (6.7%) (p value 0.032). CONCLUSIONS: Despite an absolute difference of 1.1% in the 3-month CCR, our interim analysis failed to show the non-inferiority of the hypofractionated chemoradiation. Due to the higher GI toxicities, we will continue this trial using intensity-modulated radiation therapy. REGISTRATION NUMBER AND DATE: ClinicalTrials.gov: NCT04831437, 2021.4.1.

Synchronous endometrial and ovarian cancer and its recurrent risk factors: Case series.

BACKGROUND: Synchronous endometrial and ovarian cancer (SEOC) is a relatively rare entity with indistinct clinical manifestation but have a better prognosis compared to metastatic malignancy of each organ. The aim of the study is to determine the prognosis and factors associated with recurrence of SEOC. METHODS: This case-series study was performed on 37 histologically confirmed SEOC, diagnosed and treated in our tertiary hospital from March 2009 to September 2021. Disease-free survival (DFS) and overall survival (OS) rates following indicated procedure were calculated using the Kaplan-Meier method. Univariate and multivariate Cox regression analysis were used to determine risk factors of recurrence. RESULTS: The mean age of participants was 49.38 (age range: 26-78). The most common complaints and symptoms were abdominal pain (40.5%), followed by abnormal uterine bleeding (29.7%). Most common histological presentation was endometroid type for both ovarian (46%) and endometrial (97.3%) cancers. Over the mean follow-up period of 85.54 months, 11 patients developed recurrence without mortality. Non-endometrioid histology of ovarian cancer, higher grade and stage of ovarian cancer, and omentum invasion were significantly associated with worse DFS in unvariate analysis. Lymphovascular invasion was the sole predictor of DFS in multivariate analysis. CONCLUSION: While this study was not able to investigate the risk factors of overall survival associated with SEOC, the results of this study provides an overview of clinicopathological presentation of the disease and emphasizes the importance of lymphovascular invasion in determining prognosis and DFS in SEOC.

Ovarian adenosarcoma in a postmenopausal woman: Case report and review of literature.

INTRODUCTION AND IMPORTANCE: Mullerian adenosarcoma is a rare malignancy that generally occurs in the uterine corpus but uncommonly, it may be found extrauterine. Ovarian adenosarcoma is extremely rare and often is presented in reproductive age women. Most of them are low grade and have à good prognosis except for adenosarcoma with sarcomatous overgrowth. CASE PRESENTATION: A 77-year-old menopausal woman presented with abdominal discomfort. She had severe ascites and elevated levels of CA-125, CA 19-9, and HE4 tumor markers. Adenosarcoma with sarcomatous overgrowth was diagnosed after the histopathological examination of the surgical biopsy. CONCLUSION: The possibility of endometriosis transformation to malignancy even in postmenopausal women may warrant continuous follow-up for early diagnosis of ovarian cancer, this potentially fatal disease. More studies are needed to find the best therapeutic approach to adenosarcoma with sarcomatous overgrowth.

Rare presentation of retroperitoneal leiomyosarcoma mimicking a myoma in a 46-year-old woman: A case report.

Retroperitoneal sarcoma is relatively uncommon. We share our experience in encountering retroperitoneal sarcoma with vascular and urethral adhesion in a 46-year-old woman. Given the rarity of these tumors, evaluation and management should ideally be performed in a center equipped with multidisciplinary expertise in treating sarcomas.

Resistance to single-agent chemotherapy in low-risk gestational trophoblastic neoplasia.

Background: Methotrexate (MTX) and actinomycin D (ActD) have been used as first-line chemotherapy agents in the treatment of low-risk gestational trophoblastic neoplasia (GTN). Although low-risk GTN is considered a curable disease, its reported primary remission rates of 49 to 93% reflect the difficulties of treatment and different factors influencing it. Hence, this study aimed to determine the remission rates and related factors of single-agent chemotherapy resistance in low-risk GTN patients. Methods: This retrospective study included patients with diagnosed low-risk GTN who received either MTX once a week (IM, 30mg/m2) or ActD once every two weeks (pulsed IV, 1.25mg/m2). Then, the patients were followed-up until complete remission or single-agent treatment failure to assess resistance rate and related factors. Results: Eighty-four patients were included in the study (18 patients were receiving MTX and 66 patients were receiving ActD). 85.7% of all participants achieved complete remission after first-line chemotherapy (72.2% in MTX vs 89.4% in ActD). There was a significant association for higher tumor size (P=0.046), the occurrence of metastasis (P=0.019), and pretreatment ß-HCG levels (P=0.005) with resistance to treatment. Conclusion: This study demonstrated higher tumor size, the occurrence of metastasis, and pretreatment ß-HCG levels have been associated with increased resistance to first-line chemotherapy agents.

Struma ovarii: A case report and review the literature.

INTRODUCTION AND IMPORTANCE: Struma ovarii is a monodermal teratoma which characterized by the presence of thyroid tissue. The symptoms of this tumor are nonspecific and thus misdiagnosis and indifference to other ovarian lesions are very common. CASE PRESENTATION: Herein, we described a case of struma ovarii that was successfully diagnosed and managed. The tumor is mimicking a malignant tumor based on ascites and tumor marker assessments. Although, thyroid function indices are normal. CLINICAL DISCUSSION: The initial footprint of the tumor is mostly based on incidental imaging, but definitive diagnosis is possible based on pathological studies. Surgical resection of the tumor can be led to successful treatment and prognosis. CONCLUSION: Struma ovarii is a rare tumor and also misdiagnosis is common. Regarding rarity of Struma Ovarii, the treatment option is debated. However, in postmenopausal cases with the aim of completely removing the symptoms, total abdominal hysterectomy with bilateral salpingo-oophorectomy can be occasionally indicative.

What are the determinants of parametrial invasion in patients with early stage cervical cancer: A cross sectional study.

Introduction: There was an increase in number of patients presented with early-stage cervical cancer (CC). Tumors with favorable pathological features might be candidates for less radical surgery. Methods: We retrospectively reviewed 700 patients with histologically confirmed CC between January 2011 and March 2020. Chi-square, Fisher's exact tests and multivariate logistic regression analysis were used to assess relations between parametrial involvement (PI) and clinic-pathological variables. Results: Total number of 132 patients with stage IA to IIA were eligible to participate. Squamous cell carcinoma was reported in 100 (75.8%) patients, adenocarcinoma and other tumor pathologies were found in 24(18.2%) and 8(6.1%), respectively. Considering the 2018 FIGO stage, 11 (8.4%) patients had IA, 111 (83%%) IB and 10 (7.6%) IIA. Nine patients (6.8%) had PI on permanent pathologic report. Univariate analysis demonstrated that following variables were statistically different between patients with and without PI: age ≥50, tumor size ≥ 3 cm, lower segment involvement, poorly differentiated pathology, deep stromal invasion, pelvic lymph node, lympho-vascular involvement and positive surgical margin (all p values < 0.05). Among these variables only tumor size ≥3 cm (OR: 2.1, 95% CI: 1.11-4.16, p value: 0.02), deep stromal invasion (OR: 2.2, 95% CI: 1.9-7.43, p value: 0.02) and positive surgical margin (OR: 5.1, 95% CI: 3.97-11.15, p value: 0.008) were independent risk factor of PI in multivariate analysis. Conclusions: Early stage CC might be surgically approached in a more conservative manner if patients have tumor size <3 cm and do not have deep stromal invasion in conization.

Prediction of lymphovascular space invasion in cervical carcinoma using diffusion kurtosis imaging.

BACKGROUND: This study aimed to investigate the potential relationship between diffusion kurtosis imaging (DKI)- derived parameters and lymphovascular space invasion (LVSI) in patients with cervical carcinoma. PATIENTS AND METHODS: This prospective study included 30 patients with cervical carcinoma. The patients underwent MRI, diffusion-weighted imaging (DWI), and DKI prior to surgery. The surgical pathology results were accepted as the reference standard for determining the LVSI status. The DKI-derived parameters, including mean diffusivity (MD) and mean kurtosis (MK), were measured. The apparent diffusion coefficient (ADC) value was also assessed. RESULTS: The MD value of LVSI positive cervical carcinomas was significantly lower than LVSI negative carcinomas (p-value = 0.01). MK value was significantly higher in LVSI positive tumors (p-value = 0.01). However, the ADC value did not show a significant difference between LVSI positive and LVSI negative tumors (p-value = 0.2). MD and MK parameters showed similar diagnostic accuracy in identifying the LVSI status, with the area under the curve of 0.77 and 0.78, respectively. CONCLUSION: In this study, DKI-derived parameters were associated with the LVSI status in cervical carcinomas. Further studies with larger sample size are required to confirm these results.

Uterine involvement in epithelial ovarian cancer and its risk factors.

BACKGROUND: Epithelial ovarian cancer (EOC) is an extremely aggressive and lethal carcinoma. Specific data that identify high-risk groups with uterine involvement are not available. Thus, this study aimed to evaluate a gross number of women with EOC to obtain the frequency of uterine involvement and its risk factors. METHODS: This retrospective observational study was conducted on 1900 histologically confirmed EOC women, diagnosed and treated in our tertiary hospital from March 2009 to September 2020. Data including their demographic, medical and pathological findings were collected. RESULTS: From 1900 histologically confirmed EOC women, 347 patients were eligible for participations. The mean age of study patients was 51.31 ± 11.37 years with the age range of 25 to 87 years. Uterine involvement was detected in 49.6% (173) of the patients either macroscopic (47.4%) or microscopic (52.6%) types. Uterine involvement was significantly associated with having AUB (P-value = 0.002), histological type of ovary tumor (P-value < 0.001), ovarian cancer stage (P-value < 0.001), and abnormal CA-125 concentration (P-value = 0.004). Compared to the other study patient, the patients with metastatic uterine involvement had significantly higher stage (p-value< 0.001), higher grade of ovary tumor (p-value = 0.008), serous histological type (p-value< 0.001), and a higher level of CA-125 concentration (p-value< 0.001). on the other hand, the patients with synchronous uterine cancer were significantly younger (p-value = 0.013), nulliparous (p-value< 0.001), suffered from AUB symptoms (p-value< 0.001) and had endometroid histological type (p-value = 0.010) of ovary cancer in comparison to other study patients. CONCLUSION: Considering the high prevalence of uterine involvement in EOC patients, ultrasound evaluation and/or endometrium biopsy assessment should be done before planning any treatment.

Comparison of the diagnostic accuracy of contrast-enhanced/DWI MRI and ultrasonography in the differentiation between benign and malignant myometrial tumors.

BACKGROUND: Various modalities including ultrasonography and magnetic resonance imaging (MRI) have been developed as imaging technique for screening malignant myometrial tumors, but a few studies assessed the diagnostic value of these two techniques in differentiation of benign from malignant myometrial tumors that had been the main purpose of this study. MATERIALS AND METHODS: This cross-sectional study was performed on 63 women underwent surgery for intrauterine masses that were initially assessed using MRI and ultrasound before surgery at a tertiary hospital in Tehran from 2016 to 2020. Their MRI was reviewed by a reputable radiologist in the field. The findings of histopathological assessment were considered as the gold diagnostic standard. RESULTS: The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of MRI to detect sarcoma were revealed to be 94.6%, 92.3%, 94.6%, 92.3%, and 93.7% respectively. Ultrasonography had not preferable applicability to differentiate sarcoma from benign tumors with sensitivity, specificity, PPV, NPV and accuracy of 35.1%, 88.4%, 81.2%, 48.9%, and 57.1% respectively. The diagnostic performance of both modalities was not affected by baseline clinical conditions including pain, abnormal uterine bleeding and menopausal status. CONCLUSION: MRI but not ultrasonography can effectively differentiate benign from malignant myometrial tumors.

Fertility sparing surgery in malignant ovarian Germ cell tumor (MOGCT): 15 years experiences.

AIM: We aim to evaluate the reproductive outcome of fertility-sparing surgery and chemotherapy among young women diagnosed with MOGCT of any stage. METHODS: In the current retrospective study we evaluated 79 patients with malignant ovarian germ cell tumors (MOGCT) who visited at Imam Center, Vali-e-asr Hospital, Gynecologic Oncology department during 2001-2016. Reproductive outcomes (menstruation status and childbearing) followed fertility-preserving surgery and adjuvant chemotherapy by filling questionnaires. Statistical analysis was done with SPSS software, Chi-Square Tests were done, and significance was determined at P ≤ 0.05. Results among 79 young women who underwent fertility-sparing treatment, 72 patients followed up for reproductive outcome, and 7 patients excluded because of death (3 cases), XY genotyping (3 cases), and bilateral ovarian involvement (1 case). The mean age at presentation was 23 years. (Range: 19-33 years). The 5 and 10-year disease-free survival rate was 87% and 94.4%, respectively. The overall survival rate (OSR) was 94.4% at 5 and 10 years. Regular menstruation recovered in 60 of 72 patients after treatment (83%). All patients without adjuvant chemotherapy experienced regular menstruation, while normal menstruation was retrieved in 78% in the adjuvant chemotherapy group at the end of treatment. This retrieval of regular menstruation was not dependent on the age or number of chemotherapy cycles. 19 of 26 patients who attempted pregnancy were led to delivery (73%). No one required infertility treatments. The mean of chemotherapy cycles is related to a successful pregnancy. CONCLUSION: We showed patients with MOGCT could become pregnant and give birth if they desire. The advanced tumor stage wasn't the convincing factor for avoiding fertility preservation. Fertility sparing surgery with adjuvant chemotherapy is a safe treatment and results in a high fertility rate.

Aggressive angiomyxoma of the pelvis surgical management in a case with delayed diagnosis.

INTRODUCTION AND IMPORTANCE: Aggressive angiomyxoma is characterized as a non-capsulated soft mass with the ability to progress to surrounding tissues but without metastasis to distant tissues. Slowing tumor extension leading delayed tumor diagnosis, expression of different types of hormonal receptors, therapeutic ineffectiveness of noninvasive treatment approaches and misdiagnosis have remained as the major challenges for managing this tumor. CASE PRESENTATION: Herein, we described a case of aggressive angiomyxoma located in the posterior of the uterus and vagina that as successfully managed surgically to remove tumor mass followed by gonadotropin-releasing hormone (GnRH) agonist to prevent tumor recurrence. CLINICAL DISCUSSION: Surgical resection is the treatment of choice in aggressive angiomyxoma with complete success rate, however despite such successfulness, about two-thirds of patients experienced postoperative recurrence rate that could be prevented by hormone-based therapy especially GnRH agonist. CONCLUSION: Aggressive angiomyxoma is a rare tumor with locally invasive behavior. As misdiagnosis is common imaging like MRI with DWI should be considered. The best treatment is surgical resection by experienced surgeons in tertiary referral hospitals. Even with complete resection, the recurrence rate is high. So adjuvant medical treatment seems to be necessary.

Preoperative Monocyte Count as a Mirror of Tumor Characteristics and Likelihood of Recurrence in Endometrial Carcinoma Cases

Background: Recently preoperative hematologic parameters have attracted attention for their capacity to predict tumor characteristics and recurrence. Considering the established role of tumor-associated macrophages (TAM) in the tumor microenvironment, we evaluated the role of the preoperative monocyte count as a surrogate for TAM. Methods: We retrospectively reviewed 166 patients with histopathologically proven endometrial cancers from January 2011 to March 2015 and assessed any association of preoperative monocyte count with tumor characteristics and recurrence. Results: The majority of patients had tumors with the following characteristics: endometrioid histology (83.1%), low grade (grade I-II, 71.7%) and stage I disease (68.1%). The mean ± SD monocyte, neutrophil and platelet counts were 8.23 x 109/L ± 3.56 x 109/L, 64.0 x 109/L ± 11.3 x 109/L and 261.6 x 109/L ± 74.6 x 109. Statistically significant associations were noted with between preoperative monocyte count and tumor stage (p value=0.044), recurrence (p value<0.001) and omentum involvement (p value< 0.001) but not with tumor grade (p value=0.897), depth of myometrium involvement (p value=0.479), lymphovascular space invasion (p value=0.269) and lymph node involvement (p value=0.377). Conclusion: An elevated preoperative monocyte count is related to more aggressive tumors and a higher recurrence rate in patients with endometrial cancer.

The prognostic role of preoperative serum CA125 levels in patients with advanced endometrial carcinoma.

BACKGROUND: Lifetime risk of developing endometrial cancer is 2.17%. There is controversy regarding the predictive value of Cancer Antigen 125 (CA125) in endometrial cancer as well as the significance of its relationship with prognostic factors and appropriate cut-off value. OBJECTIVE: The aim of the present study was to investigate the prognostic role of CA125 in advanced endometrial carcinoma and determination of the appropriate cut-off value. METHODS: A sample of 91 patients was retrospectively selected from a population of 501 patients suffering from endometrial cancer during 1995 to 2015 in accordance with the inclusion criteria. The relation between clinicopathological variables and CA125 were analyzed. In order to determine sensitivity and specificity of various cut-off levels, receiver operating characteristic (ROC) curve analysis was performed for associated factors confirmed by logistic regression analysis. RESULTS: In 35% of patients, CA125 values were 35 u/ml, and in 52%, the values were equal to or greater than 20 u/ml. High preoperative CA125 was significantly related with advanced stage, ovarian involvement, omental metastasis, and myometrial invasion equal to or greater than 50%. According to the ROC curve, the suitable cut-off value for CA125 in advanced stage (sensitivity = 73%, specificity = 55%, positive predictive value = 18%, negative predictive value = 78%) and myometrial invasion equal to or greater than 50% (sensitivity = 64%, specificity = 61%, positive predictive value = 47%, negative predictive value = 74%) was 20 u/ml. Further, the suitable cut-off value for CA125 in involvement of the ovaries (sensitivity = 77%, specificity = 72%, positive predictive value = 31%, negative predictive value = 95%) and omental involvement (sensitivity = 70%, specificity = 70%, positive predictive value = 22%, negative predictive value = 95%) was 35 u/ml. CONCLUSIONS: In endometrial carcinoma, due to the relationship of CA125 with numerous prognostic factors, it is recommended that CA125 measurement be included in preoperative evaluation. In case of high CA125 levels, complete surgical staging including lymphadenectomy and omentectomy should be considered.

Utility of Pelvic MRI and Tumor Markers HE4 and CA125 to Predict Depth of Myometrial Invasion and Cervical Involvement in Endometrial Cancer.

OBJECTIVE: The purpose of this pilot study was to determine whether the MRI and biomarkers human epididymis protein 4 (HE4) and CA125 correlate with depth of myometrial invasion, histologic grade, cervical involvement and nodal metastases in patients with endometrioid adenocarcinoma of the uterus. MATERIALS AND METHODS: This was a prospective, observational study in women with biopsy-proven endometrial adenocarcinoma of the uterus. Preoperative pelvic MRI was performed and concentration of HE4 and CA125 were assessed before surgery. All surgical specimens were reviewed by a single expert pathologist. The results were compared with the final histopathology report of surgical staging. RESULTS: Included were a total of 68 women with endometrioid adenocarcinoma of the uterus, most (76%) with stage I disease. Levels of serum HE4 greater than 140PM and CA125 greater than 35 ku/L were observed in 12 (17%) and 26 (38.2%) of patients respectively whose greater proportion were cases with deep myometrial invasion and high grade tumor. In the evaluation of deep tumoral invasion (> 50%) of the myometrium sensitivity, specificity, and diagnostic accuracy of MRI were 68.9%, 94.8% and 83.8% respectively. For lymph node involvement these values were 50%, 95.1% and 91.1% respectively and for cervical stromal involvement were 64.3%, 98.1% and 91.1% respectively. CONCLUSION: Higher stage, deep myometrial invasion, and lymph node or cervical stromal involvement increase diagnostic accuracy of MRI. Higher levels of HE4 and CA125 were observed in patients with deep myometrial invasion and higher grade of tumor.

Ovarian metastasis in endometriod type endometrial cancer.

BACKGROUND: The purpose of this study was to examine the rate and clinico-Pathological characteristics of ovarian metastasis of endometriod type endometrial cancer. MATERIALS AND METHODS: A retrospective study of all patients with endometriod type endometrial cancer was carried out during 1990-2009. Chi-square and Fisher's Exact tests were used to analyze all the variables. P ≤ 0.05 was considered statistically significant. SPSS software (version 18), was used for statistical analysis of the data obtained. RESULTS: Two hundred and ten patients fulfilled the inclusion criteria. Only 17 (8%) cases were identified to have ovarian metastasis. Fisher's Exact test showed that the independent risk factors of ovarian metastasis in endometrial carcinoma included pathologic grading and depth of myometrial invasion (p<0.001 and p<0.02, respectively). CONCLUSION: The risk of ovarian metastasis in the patients with well to moderately differentiated endometriod type endometrial cancer and myometrial invasion limited to less than one half of the myometrium is minimal. Therefore, it is possible to preserve ovaries in young women with early stage endometrioid type endometrial carcinoma, but it is better to remove and freeze ovarian tissue to save fertility without the recurrence risk of ovarian cancer.

Frequency of different types of ovarian cancer in Vali-e-Asr Hospital (Tehran University of Medical Sciences) 2001-2003.

Purpose of this study was to report histology specific age adjusted ovarian cancer incidence rates from 2001-2003 in Tehran University Hospital (valie-Asr hospital). This was a case series study including all microscopically confirmed cases of ovarian malignancies from 2001-2003. There were 152 cases of ovarian cancer, 102 (67.1%) epithelial type, 26 (17.1%) germ cell tumors, 14 (9.2%) sex cord stromal and 10 (6.6%) metastatic ovarian tumors. Present results were compatible with results from nonwestern countries. Epithelial type tumors and sex cord-stromal tumors were more prevalent after the age 50 (40 and 44.4% consequently). Germ cell tumors were more prevalent before 20(16 cases, 61.5%) (chi2 = 42.54, p-value = 0.000). Stage of disease in epithelial type tumors was advanced in most of patients but most germ cell tumors and sexcord-stromal tumors were stage I (chi2 = 19.6, p-value = 0.000). Present study showed that epithelial ovarian tumors in comparison to western countries are less frequent in Iran but still this histologic type is the most prevalent type of ovarian malignancy in this area of the world. Of course in younger patients we can predict more probability of germ cell tumors with more localized disease and better prognosis.
