Type-specific human papillomavirus prevalence in women referred for colposcopy in Tehran.

Background and Objectives: Although several studies have been achieved on the frequency of the HPV types among women with cervical cancer in Iran, HPV-positive samples were in some cases directed to specific-primer genotyping of HPV 16 and 18. Therefore, the other HPV types are underestimated. Several studies have also reported a greater prevalence of HPV 16 in cervical cancer in Iran than in the world. To clarify these subjects, the distribution of HPV types in women referred for colposcopy in Tehran was investigated. Materials and Methods: In this cross-sectional study, a total of 148 cervical samples from women with normal, atypical squamous cells of undetermined significance, cervical intraepithelial neoplasia I-III, and invasive cervical cancer histopathology were included. HPV was detected by PCR assay and all HPV-positive specimens were subjected to direct nucleotide sequencing. Results: Our results demonstrated that the total prevalence of HPV was 92.5%. The five most common HPV types were HPV 16 (49.3%), 18 (14.8%), 6 (7.4%), 31 (4.1%), and 11 (2.7%). About the histopathological stage, HPV 16 and 18 were dominant in all studied groups. In cervical cancer, HPV 16 and 18 were detected in 60% and 20% of cases, respectively. Conclusion: HPV 16 and 18 were the most common in cervical cancer in Iran.

The expression analysis of human endogenous retrovirus-K Env, Np9, and Rec transcripts in cervical cancer.

While infection with high-risk human papillomavirus (HPV) types is necessary for cervical cancer (CC) development, it is not enough, and other risk factors are required. Several studies have reported the activation of HERV-K in different cancers; however, the investigation of HERV-K expression levels in CC is scarce. In this study, it was hypothesized that activation of HERV-K could play an essential role in CC development. In this order, the expression levels of HERV-K Env, Np9, and Rec transcripts were investigated on 147 normal to CC uterine cervical tissues using quantitative real-time PCR. The significantly higher levels of HERV-K Env and Np9 transcripts were found in patients with cervical intraepithelial neoplasia (CIN) II-III and CC groups compared to those in the normal/CIN I group. Expression of Rec transcript was also higher only in the CC group than normal/CIN I group. Among CC patients, meaningfully higher levels of HERV-K Env and Np9 transcripts were found in patients with squamous cell carcinoma rather than in adenocarcinoma. When only the HPV 16 positive samples were investigated, it was found that the mean difference in Env and Np9 mRNA levels was meaningfully higher among precancer lesions and the cancer group in comparison with the normal group. However, the Rec mRNA level showed no significant differences. The association between the expression of HERV-K genes was investigated, and a significant positive correlation of Env expression with Np9 transcript was found only in the group with precancer lesions (R = 0.6, p = 0.0037). Moreover, a significant positive correlation was found between Rec and Np9 transcripts in patients with normal cervix tissues (R = 0.26, p = 0.033). However, no correlations were observed between the expression of Env and Rec in the three groups. In conclusion, our results showed that HERV-K transcripts, especially Env and Np9, upregulated during cervical lesion progression. These findings highlight the potential use of HERV-K Env and Np9 as biomarkers for CC diagnosis and prognosis. Further investigation is needed to determine the clinical utility of these markers and whether targeting HERV-K oncogenes could be a viable therapeutic strategy for CC.

Modified MR scoring system for assessment of sonographically indeterminate ovarian and adnexal masses in the absence of dynamic contrast-enhanced.

OBJECTIVES: Dynamic contrast-enhanced (DCE) MRI is not available in all imaging centres to investigate adnexal masses. We proposed modified magnetic resonance (MR) scoring system based on an assessment of the enhancement of the solid tissue on early phase postcontrast series and diffusion-weighted imaging (DWI) with apparent diffusion coefficient (ADC) map and investigated the validity of this protocols in the current study. MATERIALS AND METHODS: In this cross-sectional retrospective study, pelvic MRI of a total of 245 patients with 340 adnexal masses were studied based on the proposed modified scoring system and ADNEX MR scoring system. RESULTS: Modified scoring system with the sensitivity of 87.3% and specificity of 94.6% has an accuracy of 92.1%. Sensitivity, specificity, and accuracy of ADNEX MR scoring system is 96.6%, 91%, and 92.9%, respectively. The area under the receiver operating characteristic curve for the modified scoring system and ADNEX MR scoring system is 0.909 (with 0.870-0.938 95% confidence interval [CI]) and 0.938 (with 0.907-0.961 95% CI), respectively. Pairwise comparison of these area under the curves showed no significant difference (P = .053). CONCLUSIONS: Modified scoring system is less sensitive than the ADNEX MR scoring system and more specific but the accuracy is not significantly different. ADVANCES IN KNOWLEDGE: According to our study, MR scoring system based on subjective assessment of the enhancement of the solid tissue on early phase postcontrast series and DWI with ADC map could be applicable in imaging centres that DCE is not available.

The inhibitory receptors PD1, Tim3, and A2aR are highly expressed during mesoCAR T cell manufacturing in advanced human epithelial ovarian cancer.

BACKGROUND: Chemotherapy and surgery have been the mainstays of epithelial ovarian cancer (EOC) treatment so far. Cellular immunotherapies such as CAR T cell therapy have recently given hope of a cure for solid tumors like EOC. However, extrinsic factors associated with the CAR T cell manufacturing process and/or intrinsic dysregulation of patient-derived T cells, which could be associated with cancer itself, cancer stage, and treatment regimen, may hamper the efficacy of CAR T cell therapy and promote their exhaustion or dysfunction. METHODS: To investigate the association of these factors with CAR T cell exhaustion, the frequency of T and CAR T cells expressing three immune inhibitory receptors (i.e., TIM3, PD1, A2aR) generated from T cells of EOC patients and healthy controls was measured during each stage of CAR T cell production. RESULTS: Our findings revealed that primary T cells from EOC patients show significantly elevated expression of immune inhibitory receptors, and this increase was more prominent in patients undergoing chemotherapy and those with advanced cancer. In addition, the CAR T cell manufacturing process itself was found to upregulate the expression of these inhibitory receptors and more importantly increase the population of exhausted mesoCAR T cells. CONCLUSIONS: Our observations suggest that intrinsic characteristics of patient-derived T cells and extrinsic factors in CAR T cell production protocols should be considered and properly counteracted during CAR T cell manufacturing process. In addition, mitigating the signaling of immune inhibitory receptors through pharmacological/genetic perturbation during CAR T cell manufacturing might profoundly improve CAR T cells function and their antitumor activity in EOC and other solid tumors.

Endocervical adenocarcinoma implantation in episiotomy scar: a case report and review of the literature.

BACKGROUND: Cervical cancer is a rare malignancy in the 1st months of pregnancy. Implantation of this cancer in an episiotomy scar is a condition that is rarely reported. CASE PRESENTATION: We reviewed the literature on this condition and reported a 38 year-old Persian patient who had been diagnosed with cervical cancer, clinically stage IB1, 5 months after a term vaginal delivery. She underwent transabdominal radical hysterectomy with ovarian preservation. Two months later she presented with a mass-like lesion in the episiotomy scar which was proved to be of cervical adenocarcinoma origin after biopsy. The patient was scheduled for chemotherapy with interstitial brachytherapy, an alternative to wide local resection, with successful long-term disease-free survival. CONCLUSION: Implantation of adenocarcinoma in an episiotomy scar is a rare occurrence in patients with a history of cervical cancer and previous vaginal delivery near the time of diagnosis which requires extensive local excision as a primary treatment when feasible. The proximity of the lesion to the anus can lead to major complications of extensive surgery. Alternative chemoradiation combined with interstitial brachytherapy can be successful in eliminating cancer recurrence without compromising the functional outcome.

Cervical intraepithelial neoplasia in non-16/18 high-risk human papilloma virus positive/cytology negative women: An alternative approach in poor resource areas.

OBJECTIVE: Because the specific prevalence and carcinogenesis of non-16/18 high-risk (hr) Human Papillomavirus (HPV) is not fully understood, we designed a study with aim of evaluating the risk of high-grade cervical intraepithelial neoplasia (CIN) in non-16/18 hr-HPV positive/cytology negative cases and assessing the distribution of non-16/18 hr-HPV subtypes. MATERIALS AND METHODS: This cross-sectional study was conducted on 138 non-16/18 hr-HPV positive/cytology negative women, who were referred to the gynecologic oncology clinic of Yas hospital, affiliated with Tehran University of Medical Sciences, January 2021 to 2022. RESULTS: Among the detected types, HPV 31 was the most frequent type. 63 cases underwent biopsy as indicated based on colposcopic examination with acetic acid 3% application among which 34 had normal results. In the remaining 29 cases, 25 had insignificant findings. CIN2 was reported in 2 cases, one with HPV 31, 45, 58, and the other with HPV 58. CIN3 was also detected in 2 cases, one with HPV 31 and the other with HPV 35, 45. The overall incidence of high-grade CIN was 2.8%. A statistically significant (P-value = 0.046) difference was detected between patients with high-grade CIN compared with the others regarding the Hookah usage. CONCLUSION: The risk of CIN among non-16/18 hr-HPV positive/cytology negative cases is noticeably low. Based on ASCCP guidelines return testing at 1 year without immediate colposcopy seems sufficient; however, because of many reasons doing immediate colposcopy rather than 1-year follow-up may be a more accessible approach in resource poor, low-income countries such as ours.

The impact of lymphovascular space invasion on survival in early stage low-grade endometrioid endometrial cancer.

BACKGROUND: The lymphovascular space invasion (LVSI) is suggested as a prognostic factor for endometrial cancer in many studies, but it has not yet been employed in FIGO staging system. The present study was aimed to evaluate the impact of LVSI on survival in patients with early stage endometrioid endometrial cancer. METHODS: This retrospective cohort was conducted on early stage endometrial cancer patients who underwent surgical staging [total abdominal hysterectomy and bilateral salpingo-oophorectomy (TAH/BSO)] and omental biopsy at Referral Teaching Hospitals of Tehran from 2005 to 2021. Patient's age, menopause status, tumor grade, tumor size, depth of myometrial invasion, LVSI and lower segment involvement were recorded. Data were analyzed with SPSS 22. RESULTS: 415 patients with stage I and grade 1-2, endometrioid endometrial cancer were analyzed. 100 patients (24.1%) were LVSI-positive. 3-year and 5-year survival rates were 97.1% and 88.9%, respectively. Recurrence occurred in 53 patients (12.8%). 3-year overall survival rates in LVSI-negative and LVSI-positive were 98.7% and 92%. These rates for 5-year survival were 92.1% and 79%, respectively. Recurrence rates in LVSI-negative were 8.9% while it was 25% in LVSI-positive cases. Multivariate analysis showed that LVSI has significant correlation with 3-year and 5-year overall survival rates. CONCLUSIONS: LVSI in early stage endometrial cancer significantly and independently influences 3-year and 5-year survival rates and acts as a strong prognostic factor in these patients. LVSI should be implemented in endometrial cancer staging systems due to its significant correlation with cancer recurrence rates and 5-year survival rates.

Predictive value of B-human chorionic gonadotropin for progression of molar pregnancy to persistent gestational trophoblastic neoplasm.

BACKGROUND: This study aimed to assess the predictive value of B-human chorionic gonadotropin (B-hCG) for progression of molar pregnancy to persistent gestational trophoblastic neoplasm (GTN). METHODS: This cohort study evaluated 126 patients with molar pregnancy. The patients were selected among those presenting to Yas Hospital in 2016-2017. All female patients with molar pregnancy hospitalized in this hospital who underwent evacuation were enrolled. After evacuation, the patients underwent ultrasound examination to measure their endometrial thickness. Also, presence of complete or partial mole was pathologically assessed. The B-hCG titers were measured before and at 48 h, 1 week, 2 weeks, and 3 weeks after the evacuation. The follow-up was continued until the B-hCG titer was negative or the patient was classified as a case of GTN according to the FIGO classification. Data were analyzed by the independent t-test, Mann-Whitney Test, χ2 test, receiver operating characteristic (ROC) curve, and linear regression. RESULTS: Of 126 patients with molar pregnancy, 13 developed GTN. The mean ratio of pre-evacuation B-hCG titer to the value at 3 weeks after evacuation was 0.02±0.005 in the full recovery and 0.06±0.04 in the GTN group, indicating an area under the curve (AUC) of 0.904. CONCLUSIONS: The ratio of pre-evacuation B-hCG titer to the value at 3 weeks after the evacuation of mole can serve as an excellent predictor for development of GTN.

Sexual Quality of Life in Gynecological Cancer Survivors in Iran.

OBJECTIVE: Patients with gynecological cancer might suffer from suboptimal sexual quality of life. This cross sectional study aimed to assess the sexual quality of life in the survivors of gynecological cancers and was recruited in a teaching hospital affiliated to Tehran University of Medical Sciences between 2018 and 2020. MATERIAL AND METHODS: The data was collected by a web-based platform with validated self-administered questionnaires including demographic information, and the Sexual Quality of Life-Female (SQOL-F) questionnaire. The data were analyzed using appropriate tests. RESULTS: Totally, 42% (106) of the participants had a sexual relationship in the last 6 months. The mean (SD) of sexual quality of life score was 46.84 (11.86) with the range of 0-90. The patients with cervical cancer had a worse sexual quality of life in Psychosexual Feelings (P=0.048) and Self-Worthlessness (p=0.036) compared with other gynecological cancers. Sexual quality of life did not improve or worsen over time. CONCLUSION: It is concluded poor sexual quality of life need further attention in the traditional societies and healthcare providers are urged to improve their sexual quality of life.

The importance of correct radiological diagnosis in (adenoma malignum): a case report.

Minimal deviation adenocarcinoma (MDA) of the cervix otherwise known as adenoma malignum is a rare variation of cervical adenocarcinoma. Radiological evaluation plays a great role to ensure an early diagnosis. Here, we report a 48-year-old woman who was presented with a mucoid vaginal discharge 10 years after a supracervical hysterectomy. Despite normal biopsy and cytology, magnetic resonance imaging showed a large cervix and multiple cervical cysts that considered adenoma malignum as a differential diagnosis. She underwent surgery and the pathology confirmed the adenoma malignum. In conclusion, radiologists, as well as gynecologists, and also pathologists may consider MDA among the differential diagnosis in patients with a vaginal discharge and multicysts in the cervix even after hysterectomy despite normal cytology and biopsy.

Quality of Life in Patients with Gynecological Cancers: A Web-Based Study.

INTRODUCTION: Gynecological cancers are common in adult women. One of the most important goals in the management of these patients is to improve quality of life, along with survival as a traditional outcome. The aim of this study was to evaluate quality of life in gynecological cancers in Iran. METHODS: This cross-sectional study was performed on a sample of patients with gynecological cancers including uterine, ovarian, cervical, and vulvovaginal attending a teaching hospital affiliated to Tehran University of Medical Sciences between 2014 and 2019. The data was collected by a web-based platform with validated self-administered questionnaires including demographic information, the EORTC QLQ-C30 and the Hospital Anxiety and Depression (HADS). The data were analyzed using appropriate tests. RESULTS: In all 251 patients were studied. The mean age of patients was 52.8±12.4 years and 43% had uterine, 30% had ovarian, 25% had cervical, and 2% had vulvovaginal cancer. The mean global quality of life score as measured by the EORTC QLQ-C30 was 59.8 ± 24.9. Women with ovarian cancer had the highest and women with cervical cancer had the lowest global quality of life score. There were significant differences in emotional, cognitive and global quality of life by cancer diagnosis (p <0.05). Although not significant, overall physical, role, cognitive and social functioning was found to be better in women who had been treated with surgery. The mean anxiety and depression score were 8.7± 5.0 and 7.1 ± 5.2, respectively. CONCLUSION: The results demonstrated that patients with gynecological cancers had a low quality of life, and experience higher anxiety and depression.

Assessment of Cervical Cancer Molecular-Based Screening Tools; HPV-DNA Detection versus E6/E7 mRNA Testing; First Report of a Prospective Cohort Study among Iranian Women.

BACKGROUND: Human papillomavirus (HPV) has been found as the most considerable causes of cervical cancer. Recently, several molecular methods have been introduced to increase the accuracy of the screening programs and decrease the mortality rate. Among these methods, mRNA-based methods have more advantages as they assess the expression level of HPV E6 and E7 oncogenic mRNAs. This study aimed to evaluate the results of HPV RNA- and DNA-based methods among Iranian women population with normal cytology results. METHODS: Overall, 4640 women were enrolled referred to the Gynecology Oncology Ward of Vali-e-Asr Hospital, private and academic clinics, Tehran, Iran from Jan 2016 to Apr 2018. To assess the HPV-DNA infection INNO-LiPA® HPV Genotyping Extra-II kit was used. For HPV-RNA assessment, Aptima HPV Assay and in house HPV-RNA genotyping methods were applied. RESULTS: The positivity rates of HPV infection according to DNA- and RNA-based methods were 18.0% and 11.2%, respectively (P<0.001). The positive predictive value, negative predictive value, specificity and sensitivity of DNA-based method in contrast with RNA-based method were 59.2% (56.6-61.6), 99.4% (99.0-99.6), 91.7% (90.8-92.6) and 95.2% (93.0-96.9) respectively. CONCLUSION: At the present study for prognosis of cervical cancer, RNA-based method seemed to be more specific in contrast to DNA-based method. Patient follow up and further studies will be conducted in order to clarify the clinical sensitivity and specificity of the two methods.

Five-Day Intravascular Methotrexate Versus Biweekly Actinomycin-D in the Treatment of Low-Risk Gestational Trophoblastic Neoplasia: A Clinical Randomized Trial.

OBJECTIVES: Methotrexate (MTX) and Actinomycin-D (Act-D) are effective drugs used in the treatment of low-risk gestational trophoblastic neoplasia (LRGTNs). The aim of the present study was to compare intravenous (IV) MTX and IV Act-D in the treatment of LRGTNs. MATERIALS AND METHODS: Sixty-two patients with LRGTN were enrolled in a prospective randomized clinical trial between 2010 and 2013 in Moheb e Yas Hospital, Tehran University of Medical Sciences. Primary treatment regimens were IV MTX, 0.4 mg/kg daily for 5 days every 14 days (25 mg maximum daily dose), and IV Act-D, 1.25 mg/m (2 mg maximum dose) every 14 days. RESULTS: Thirty-two and 30 patients were enrolled to MTX and Act-D groups, respectively. Complete remission after receiving first-line chemotherapy was achieved in 79% of all cases, 80% in the Act-D group and 78.1% in the MTX group.Twenty percent of the Act-D patients and 21.9% of the MTX patients showed resistance to the first-line chemotherapy, of which 16.7% and 15.6% responded completely to the second-line monotherapy, respectively. Multiple drug therapy was needed in 3.3% of the Act-D group and 6.3% of the MTX group.We did not find any correlation between treatment response and beta-human chorionic gonadotropin level, uterine mass size, lung metastasis, antecedent pregnancy, and duration from diagnosis to treatment. Adverse effects were not statistically different between the 2 groups. CONCLUSIONS: Single-agent chemotherapy in the treatment of LRGTNs resulted in an overall complete remission rate of 79%, 80% in the Act-D group and 78.1% in MTX group, with no statistically significant difference. Whereas this study represents an important step in comparing single-agent treatments, comparison of other regimens will be required to determine the optimal single-agent therapy.

Comparison of clinicopathologic variables in coexistence cancers of the endometrium and ovary: A review of 55 cases in an academic center in Iran.

BACKGROUND: The coexistence primary cancers of the endometrium and ovary are relatively uncommon. The purpose of this study was to characterize patients diagnosed primary synchronous endometrial and ovarian cancer (SEOC), endometrial cancer (EC) with ovarian metastasis, and ovarian cancer (OC) with endometrial metastasis and compare clinicopathologic variables and prognosis. MATERIALS AND METHODS: All the patients with diagnosis of both endometrium and OC, who hospitalized between 2002 and 2012 in an academic center affiliated to Tehran University of Medical Sciences, were evaluated with respect to different clinicopathologic variables, follow-up times, and outcomes. RESULTS: Fifty-five patients had been diagnosed with both endometrium and OC. 17, 26, and 12 patients were diagnosed as SEOC, EC, and OC, respectively. The frequency of abnormal uterine bleeding was significantly lower in OC (16.7%) compared to others (58.8% in SEOC and 53.8% in EC). However, the abdominal/pelvic pain was significantly higher in OC (50%) compared to others (35.3% in SEOC and 34.6% in EC) (P < 0.05). Complex atypical hyperplasia (87.5%), endometriosis (88.8%), and endometrioid carcinoma (54.5%) was observed most in SEOC group. The duration of follow-up time was between 3 and 171 months with a mean of 16 months. There was no death in SEOC who followed. Survivals of patients between three group were statistically significant (P = 0.032). CONCLUSION: Our results showed that overall survival (OS) and progression-free survival (PFS) of SEOC patients is better than those with EC and OC (P = 0.032).

Human chorionic gonadotrophin as an indicator of persistent gestational trophoblastic neoplasia.

BACKGROUND: Gestational trophoblastic neoplasia (GTN) disease is excessive and inappropriate proliferation of trophoblast after termination of the pregnancy. Many attempts have been made to improve follow-up procedures, but no studies have evaluated Human Chorionic Gonadotrophin (HCG) as a post treatment indicator. Thus we aimed to know ß-HCG variability in post treatment pregnancies. METHODS: 40 Molar affected pregnancies were followed post-surgical treatment by serum ß-HCG level in a tertiary level hospital. All subjects were treated by evacuation and followed by ß-HCG every week for three weeks, then every month for six months. RESULTS: 30 women were normal (group I) and 10 (group II) diagnosed as GTN cases. Serum ß-HCG which obtained serially shown significant differences between two groups (p=0.001). The quantity of ß-HCG/week had significantly higher level than normal females (p<0.001) CONCLUSION: Our results suggested that ß-HCG serum level could be used as a strong indicator for identifying affected patients at early stage.

Clinical response to a second uterine curettage in patients with low-risk gestational trophoblastic disease: a pilot study.

OBJECTIVE: To determine the curative effect of a repeat uterine evacuation in patients with low-risk gestational trophoblastic neoplasia. STUDY DESIGN: Patients with low-risk gestational trophoblastic neoplasia (GTN)(N=12), diagnosed according to the International Federation of Gynecology and Obstetrics 2002 guidelines, were enrolled in a prospective cohort study. Primary outcomes were need for chemotherapy after second uterine evacuation and number of chemotherapy courses needed to achieve complete remission. RESULTS: Ten patients (83%) did not require chemotherapy and were cured bya second curettage. Two patients failed to respond to the second curettage and received single-agent chemotherapy with actinomycin-D (1.25 mg/m2 biweekly, slow intravenous administration). Both patients responded to chemotherapy as second-line therapy. A 100% remission rate was achieved, with no recurrence at the 1-year follow-up. One patient (8%) had a uterine perforation. CONCLUSION: Second curettage has a favorable response rate. It seems reasonable to perform a second curettage in patients with low-risk GTN in settings where serum beta-hCG assay follow-up is highly reliable and available. However, its potential complications and inconvenience must be discussed critically with each patient.

Performance of pregnant women on folic acid intake.

The cause of neural tube defects (NTDs) is multifactorial and in this case folic acid has an important role. Since the neural tube is closed during 21-28 days of pregnancy, most of women are not informed about their pregnancy at this time, and as a result the golden time of folic acid consumption is missed. The aim of this study was evaluating the performance of pregnant women attending to Tehran Women's Hospital in regard to folic acid intake during pre-conceptional period between 2011 and 2012. This cross-sectional study was conducted in 370 pregnant women attending the prenatal clinic of a hospital affiliate to Tehran University of Medical Sciences between 2011 and 2012. Data were collected through interview using a questionnaire. Although 70% of the pregnancies were planned, but 70.5% of pregnant women had not taken folic acid before conception or in necessary time. There was found a significant relationship between level of education, history of abnormalities in children and the number of abortions and taking folic acid before pregnancy (P=0.005, P=0.000 and P=0.000, respectively).

Acceptable predictive accuracy of histopathology results by colposcopy done by Gynecology residents using Reid index.

OBJECTIVE: The aim of this study was to determine the strength of the correlation between colposcopic impression according to Reid colposcopic index (RCI) done by Gynecology residents and biopsy histology in a university hospital. METHODS: Colposcopy was performed on 260 women. According to RCI, the scores zero, one, or two were given to each of four standardized colposcopy patterns (acid staining, iodide staining, margin of lesion, and vascular pattern) and the total score was calculated. In those with multiple lesions, the patterns with the highest score were considered. Then the biopsy was obtained from the lesion and put in formalin for pathological evaluation. RESULTS: There was a statistically significant association between colposcopy findings and histopathology findings and the score was increased as parallel as malignancy grade (r = 0.680, P < 0.05). The highest sensitivity and specificity for diagnosis of each CIN also were related to staining with acetic acid. For high-grade CIN lesions, the highest specificity was related to staining with acetic acid, but the sensitivity was equal for four findings. CONCLUSION: Colposcopy using RCI yields a good correlation with histology results. It also showed that colposcopy done by Gynecology residents using RCI is a feasible and acceptable cervical cancer screening method in a university hospital.

Reproductive factors associated to human papillomavirus infection in Iranian woman.

OBJECTIVE: In recent years, humman papilomaviruses (HPV) infection is the most common type of sexual trasmitted diseases (STD) in majority of countries. It's a significant source of morbidity and mortality worldwide. In this study, we aimed to compare the history of reproductive disease between two groups of Iranian women with and without HPV infection through colposcopy precedure. MATERIALS AND METHODS: This case -control study included 210 women reffered to a training gynecology hospital of Tehran University of Medical Science in Tehran. Case group was composed of 70 women with diagnosis of HPV infection, while control group was composed of 140 women with no sign of mentioned-infectious diseases of the control group. Reproductive history was prepared using the standard questionnaire, and obtianed data were analized by SPSS 20. RESULTS: OUR FINDINGS SHOWED THAT THE RISK FACTORS FOR HPV INFECTION WERE AS FOLLOWS: low parity (p = 0.000), reduction of number of weekly sexual intercourse (p = 0.000), no consumption of oral contraceptive pill (OCP) (p = 0.006), and history of withdrawal contraceptive method (p = 0.001). CONCLUSION: Improvement of our knowledge about reproductive factors associated with HPV may help us to identify women at risk and to develope different methods of preventive interventions.

Comparison of pulsed actinomycin D versus 5-day methotrexate for the treatment of low-risk gestational trophoblastic disease.

OBJECTIVE: To determine the effectiveness of 2 standard chemotherapy regimens for low-risk gestational trophoblastic disease according to the International Federation of Gynecology and Obstetrics (FIGO) staging system. METHODS: From 2008 until 2010, 75 women with low-risk gestational trophoblastic disease received either pulsed actinomycin D (n=50) or 5-day methotrexate (n=25). The primary remission rate, the duration of treatment, the number of treatment courses, and the adverse effects were compared. RESULTS: The complete remission rates were 90% for the actinomycin D group and 68% for the methotrexate group (P=0.018). The mean number of chemotherapy courses administered to achieve complete remission (including courses of second-line therapy) was 3.1 in the methotrexate group and 5.3 in the actinomycin D group (P=0.01). No major adverse effects were experienced in either treatment group and there were no significant differences in terms of adverse effects. Second-line chemotherapy was indicated for 11 patients. CONCLUSION: Based on the present study, pulsed actinomycin D seems to be an appropriate first-line treatment for patients with low-risk gestational trophoblastic disease.
