The standard treatment for advanced ovarian cancer consists of cytoreductive surgery associated with a platinum/paclitaxel-based chemotherapy. Over than 50% of patients with advanced ovarian cancer will develop recurrent disease. For those patients who have recurrence of disease at least six months after initial therapy, the paclitaxel- platinum combination has been shown to be a superior treatment to platinum monotherapy. However, many patients develop clinically relevant neurotoxicity, frequently resulting in treatment discontinuation. The efficacy and safety of an alternative regimen that dose not show significant neurotoxicity were evaluated by comparing gemcitabin- carboplatin with carboplatin in platinum sensitive recurrent ovarian cancer patients in a Gynecologic Cancer InterGroup trial in Canada and European Organization for research and treatment of Cancer Gynecological Cancer Group. But this study was not done in Iran."n"n Methods: We performed a study with escalating doses of gemcitabin combined with carboplatin in 21 patients. All patients who were treated in Vali-Asr hospital between 2003- 2005 evaluated. Gemcitabin with dose of 800mg/m2 was given on days 1, 8 and 15 followed by one week rest period for a 28 day cycle. Combine with carboplatin with AUC 4 given on day 2. All patients with surgically resected, histologically confirmed epithelial ovarian cancer and who had failed first- line platinum chemotherapy were allocated to this study."n"n Results: Median age was 49 years (range 23-78 years). Median follow-up was six months (range 4-22). Total of 87 cycles of chemotherapy were administered with median number of four (range 2-6 cycles). Thrombocytopenia (grade I) and leucopenia (grade I) were seen in 4.75% and 9.52% of patients."n"n Conclusion: Gemcitabin and carboplatin Combination was tolerated in patients with recurrence of ovarian cancer.

Background: The aim of this study was to compare the outcome of treatment for ovarian cancer patients who have been treated by gynecologist oncologists and patients who have been treated by general gynecologists or general surgeons. Methods: We enrolled in this cohort retrospective study all patients diagnosed with primary ovarian cancer in Vali-e-Asr Hospital, Tehran, Iran, between April 1999 and January 2005. A total 157 consecutive patients with ovarian cancer were available for analysis. Of these, 60 patients were treated by gynecologist oncologists and 95 by general gynecologists, and two patients were treated by general surgeons. Results: The number of patients who underwent optimal cytoreductive surgery (residual tumor

Background: Although endometrial cancer is primarily a disease of the postmenopausal female, 25% of patients are premenopausal, with 3-5% in women 40 years old or younger. The younger group of women with endometrial carcinoma are frequently nulligravid with a history of infertility, and a strong desire to preserve fertility. This may pose a therapeutic dilemma for both patients and treating physician. Case report: We reported 3 young patients with atypical; complex hyperplasia or early stage endometrial cancer that treated with conservative hormonal therapy. Conclusion: Medical treatment of young patients with endometrial carcinoma and complex atypical hyperplasia who wish to preserve fertility is a reasonable and appealing option. A comprehensive evaluation prior to counseling the patient should include A complete history and physical examination. A formal D&C with review of history with an experienced gyn-onc pathologist. Evaluation of the pelvic and abdomen preferably with contrast-enhanced MRI or transvaginal ultrasound. In patients found to have a clinical stage I grade I tumor and who want to preserve fertility , thorough counseling include risks and benefits, and explanation that the data is partial and incomplete due to the lack of appropriate controlled studies is mandatory. In patients considered for medical treatment, a high dose progestin regimen should be started with endometrial sampling every 3 months until complete regression of the tumor is documented. Although most responses are long standing, there is a small risk of progression during or after cessation of progestin therapy.

Background: Access to a safe and efficient chemotherapy regimen for improving the survival and live quality is a goal in ovarian carcinoma. Despite surgery is the base treatment of ovarian cancer, but in most patients chemotherapy is used due to progression of their disease. This study designed to compare two important chemotherapy regimens. Methods: This historical cohort study compared two chemotherapy regimen; cisplatin (75mg/m2)+ cyclophosphamide (750mg/m2), versus taxol (175mg/m2)+ carboplatinium (GFR+25)AUC; between 1998-2005 in valiasr hospital. In this study toxicities of two regimes were compared. The survival function in these two groups were analysed with Kaplan-Meire curve. Results: Gastrointestinal and mucosal toxicity were significantly higher in CP group compared TC group (p=0.02). Also there were no significant relation between decrease of serum CA125 and patient remission length in CP group but in other group with decrease of CA125 in lower than three cycle we had an increase in patient remission period. (P=0.02). Disease free interval in cisplatin group was longer versus taxol group (p

This study was designed to assess the role of first-line chemotherapy with 5-FU and platinum in the treatment of advanced or recurrent cervical cancer, ten patients with advanced or recurrent cancer of the cervix, with no prior chemotherapy were entered in phase II trial, from Oct. 2000 to Nov. 2001. Eight patients were treated with cis-platinum (50 mg/m2 over 60 minutes in first day) followed by 5-FU (1 g/m2 over 24 hours for 4 days) and two patients with impaired renal function were treated with carboplatin (300 mg/m2 over 15 minutes in first day) followed by 5-FU (1 g/m2 over 24 hours for 4 days) every three weeks, until progression of disease or prohibitive toxicity had been observed. Median age was 52 years (range: 28-70 years). Ten patients received a total of 42 cycles of chemotherapy. The mean number of chemotherapy cycles was 4.2 (median 4, range: 3-7). Three patients had partial response (30%, CI, 1.7%-58.5%). Mean response duration was 198 days (range: 122-273 days). Four patients required red blood cell transfusions; three of them had grade II and one of them grade III nausea and vomiting Two had fever and neutropenia (one developed acute renal insufficiency), and there wee no treatment related mortalities. First-line chemotherapy with platinum and 5-FU for advanced recurrent cervical cancer is promising and deserves consideration for large phase III trials.

To evaluate the effectiveness of conjugated estrogen (Premarin) and progesterone in twenty-one postmenopausal women who had been menopause one year, we tested during a 6-month period the serum lipoprotein levels in subjects who offered by premarin in dosage of 0.625 milligram for days 1 to 25 and oral medroxy progestrone acetste for days 15 to 25 of a 30-day cycle. Twenty-one subjects completed at least 6-month follow-up serum total cholesterol, low density lipoprotein (LDL) cholesterol, high density lipoprotein (HDL) cholesterol, very low density lipoprotein (VLDL) cholesterol and triglycerid (TG) measurements by calorimetric method. The results, six months after treatment, is compared to before treatment. The median change in biochemical studies showed significant decrease in serum total cholesterol (248.85 compared with 229.4, P

It this prospective cross sectional study out-patient endometrial biopsy by PIPELLE was compared with diagnostic curretage (D&C) in patients suffering of Abnormal Uterine bleeding (AUB). Diagnostic accuracy, sufficient tissue sampling, intensity of pain and effective factors in biopsy results were the evaluated parameters in this study. In 70 patients with complaint of AUB (20 of them were post-menoupsal age admitted in hospital for D&C) endometrial biopsy was conducted by PIPELLE before operation and the results were compared. 96% of total patients (67) and 91% of patients with post menopause age had tolerance of undergoing out-patient PIPELLE biopsy of endometrium. 79% of these individuals complained of mild pain and 21% of moderate pain. Endometrium biopsy by PIPELLE in 77% of patients had similar accurate diagnostic results as compared to D&C. PIPELLE in 34% of patients (24) could not be conducted with the same accuracy of D&C patients, although in 14 (20%) of them, notissue samples could be collected by D&C. In none of these methods endometrial hyperplasia or endometrial cancer were detected. This study showed that in 77% of the total patients, the extra cost and general anesthetical risk of D&C could have been eliminated, by utilization of out-patient biopsy with PIPELLE

The article presents a study which determines whether optimum versus suboptimal cytoreductive surgery predicts cancer antigen 125 (CA125) levels two weeks after surgery. It states that cytoreductive surgery is a crucial component of primary treatment in patients with ovarian epithelial cancer (OEC). It notes that postoperative CA125 significantly decreased in two weeks after tumor cytoreduction in patients with OEC, but its regression did not differ to optimal or suboptimal groups.

The article presents a retrospective study on the effect of ovarian cancer surgery performed by general gynecologists (GGs) and gynecologist-oncologists (GOs) on the overall survival of cancer patients. The study involves patients who were diagnosed with primary ovarian cancer in Tehran, Iran. The results of the study suggest that patients can have greater disease-free survival chances if they will be referred to the gynecologist-oncologists for optimal treatment.

OBJECTIVE: To determine the strength of correlation between colposcopic impression using Reid index and biopsy histology. METHODS: In a colposcopy referral clinic in Tehran University, Iran. Colposcopy was carried out using Reid colposcopic index (RCI) scoring system and directed biopsy on 344 women between March 2004 and October 2005 by fellows supervised by a board-certified gynecologic oncologist. Results were retrospectively compared with a previous study carried out on 353 women by the same physicians. In this previous study, the colposcopy findings did not use RCI index; the significance of association between these 2 studies was assessed by chi(2) and kappa statistics. RESULT: The association between colposcopic impression and biopsy histology was highly significant (p < .001), both in RCI colposcopy group and general colposcopy group. However, the strength of the correlation between colposcopy impression and biopsy histology in RCI colposcopy group was more than the general colposcopy group (0.74 vs 0.45). The positive predictive value of any colposcopic abnormality for any histologic abnormalities in the RCI group was 92%. The negative predictive value of a benign colposcopic impression was 70.5%. The sensitivity was 74%, and the specificity was 90.7%. CONCLUSIONS: The good correlation between colposcopic impression and histological diagnosis by using Reid index in colposcopy would produce higher agreement and strength of the correlation. Therefore, the Reid index can be used as a reproducible technique which is easy to learn in colposcopic clinic. [ABSTRACT FROM AUTHOR]

Background. Malignant melanoma of the uterine cervix is a rare neoplasm with poor prognosis. Diagnosis is confirmed by immunohistochemical methods and by exclusion of other primary sites of melanoma.Case. In this paper, we are reporting a case of a 38-year-old patient with a malignant melanoma of the uterine cervix. Diagnosis was made by histological and immunohistochemical method. The tumor was stage IB1 of the International Federation of Gynecology and Obstetrics classification. Chest x-ray and abdominopelvic computed tomography scanning were normal. A radical hysterectomy with bilateral salpingo-oophorectomy and pelvic lymphadenectomy was performed. After performing combined radical surgery and irradiation, complete remission of the tumor was achieved. The patient has been followed for 24 months. She is well without any symptoms or signs of recurrence.Conclusions. Malignant melanoma is usually misdiagnosed specially in the chronic form. The immunohistochemical study is useful for definite diagnosis. Treatment is not well established, and the disease histogenesis has been controversial for a long time. [ABSTRACT FROM AUTHOR]

Abstract Introduction Prediction of optimal cytoreduction in patients with advanced epithelial ovarian caner preoperatively. Methods Patients with advanced epithelial ovarian cancer who underwent surgery for the first time from Jan. to June 2008 at gynecologic oncology ward of TUMS (Tehran University of Medical Sciences) were eligible for this study. The possibility of predicting primary optimal cytoreduction considering multiple variables was evaluated. Variables were peritoneal carcinomatosis, serum CA125, ascites, pleural effusion, physical status and imaging findings. Univariate comparisons of patients underwent suboptimal cytoreduction carried out using Fisher's exact test for each of the potential predictors. The wilcoxon rank sum test was used to compare variables between patients with optimal versus suboptimal cytoreduction. Results 41 patients met study inclusion criteria. Statistically significant association was noted between peritoneal carcinomatosis and suboptimal cytoreduction. There were no statistically significant differences between physical status, pleural effusion, imaging findings, serum CA125 and ascites of individuals with optimal cytoreduction compared to those with suboptimal cytoreduction. Conclusions Because of small populations in our study the results are not reproducible in alternate populations. Only the patient who is most unlikely to undergo optimal cytoreduction should be offered neoadjuvant chemotherapy, unless her medical condition renders her unsuitable for primary surgery.

Abstract Background The considerable increase in life expectancy on one hand and an increase in cervical cancer among Iranian patients on the other, brings out the importance of investigating whether radical surgery can be performed safely and effectively on patients above 60 years of age. Methods In a study of historical cohort, all 22 patients 60 years and above who have undergone a Wertheim radical hysterectomy for cervical cancer from 1999 to 2005 were compared with 128 matched cases under 60 years of age who had undergone a Wertheim hysterectomy during the same calendar year. All patients were analyzed for preexisting medical comorbidities, length of postoperative stay, morbidity, and postoperative mortality. Results There was no operative mortality in either group, morbidity (minor, p = 0.91; major, p = 0.89) were statistically not different in the two groups despite the patient's above 60 years having significantly higher comorbidity prior to surgery than the younger cohort (minor, P < 0.05; major, P < 0.05). The mean postoperative hospital stay was significantly longer in the older patients (5 days vs. 3 days, P < 0.001). Conclusion Wertheim Radical hysterectomy is a safe surgical procedure in the selected population of patients 60 years and over. No differences in operative mortality or morbidity were found when compared to a cohort of patient's aged 60 years or younger.

Abstract Background The aim of this study was to analyze and describe cases of ovarian cancer in pregnant women treated at our center and to review the literature concerned, and to discuss the rationale for therapy. Methods Twenty-Three patients of ovarian malignancies during pregnancy were treated at Vali- Asr Hospital between 1991 and 2002. Data on treatment and follow-up were evaluated. Results The incidence of ovarian carcinoma associated with pregnancy in our series was 0.083/1000 deliveries. Eleven (47.8%) were found with ovarian malignant germ cell tumors, five (21.7%) with low malignant potential tumors, four (17.4%) with invasive epithelial tumors, and three (13%) with sex cord stromal tumors. Seventeen (73.9%) of the patients were diagnosed in stage I and had complete remission. Five of the six in advanced stage died. The mean follow-up was 36.3 months. The prognosis was significantly related with stage and histological type (P < 0.05). Sixteen healthy live babies were recorded in this group, and two premature newborn died of respiratory distress syndrome. Chemotherapy was administered to 44% of the patients, in two cases during pregnancy. Overall survival at 5 years was 61%. In most of case conservative surgical treatment could be performed with adequate staging and debulking. Conclusion Early finding of ascitis by ultrasound and persistent large ovarian mass during pregnancy may be related to malignancy and advanced stage. Pregnant women in advanced stage of ovarian cancer seem to have poor prognosis.

Abstract Background Placental site trophoblastic tumor (PSTT) is a rare and unique form of gestational trophoblastic disease (GTD). This tumor represents a neoplastic transformation of intermediate trophoblastic cells. We document a case of long term remission in a patient with metastatic PSTT. Case presentaion A 27-year-old patient with metastatic PSTT was treated with combination therapy (chemotherapy and surgery). Patient is alive after 10 years without any evidence of recurrence. Literature on PSTT was searched using Medline and cross references, and pertinent articles were reviewed. Conclusion With surgery and chemotherapy it is possible to achieve long-term remission in metastatic PSTT. Only a handful of previously reported cases with prolonged remission had been treated with the described combined chemotherapy and surgical approach. We suggest that this approach may be recommended for metastatic PSTT.

Abstract Background This study has evaluated urinary tract injuries and dysfunction after Radical Hysterectomy (RH) performed in patients with cervical cancer and has compared the cystometric parameters and urinary complications occurring in these patients with those occurring in patients who had undergone Simple Hysterectomy (SH). Patients and methods A prospective case-control study was conducted to evaluate urinary tract injuries (intra-operative and post-operative) and dysfunction in 50 patients undergoing RH for cervical cancer and to compare them with the same parameters in 50 patients who underwent SH for benign disease. Results Mean age in the RH group was 46.3 years and in the SH group was 50.1 (p = 0.63). There were no bladder and urethral injuries in either group of patients. There was one intra-operative ureteral injury in the RH patients but none in those who underwent SH. (p < 0.05). In the two weeks after surgery, 15% of RH patients and 11% of SH patients had experienced a urinary tract infection urinary tract infection (p = 0.61). Two week after surgery 62% of RH patients had no urinary symptoms, compared to 84% in the SH group who did (p < 0.02). Urinary residual volume, first urinary sensation and maximal bladder capacity were higher in the RH group, but this was not statistically significant. The only case of a urinary fistula appeared in a patient who received 5000 cGy radiation therapy pre-operatively, but this spontaneously healed after 3 weeks of catheterization. Conclusions Intra-operative and post-operative urinary tract complications are comparable in patients undergoing RH and SH and an expert gynaecological oncologist might be able to further decrease complications. However, radiation therapy before surgery may increase the risk of complications.

Abstract: The ability of silver ions to form reversible π-bond complexation with unsaturated hydrocarbons can be utilized to separate olefins from paraffins using a solution of AgNO3 dissolved in an ionic liquid (IL). The process is suggested because of zero vapor pressure of the solvent, which results in higher purity of the separated product in comparison to when an aqueous AgNO3 solution is applied. In the present study, 1-butyl-3-methylimidazolium nitrate ([Bmim]NO3), an IL that can dissolve AgNO3, is applied as the solvent. The absorption of ethylene from a gaseous mixture of ethylene/ethane with constant flowrate in the silver nitrate dissolved media is investigated in silver nitrate concentrations of 1, 2 and 5M, and temperatures within the range of 5–35°C. The absolute absorptivity of ethylene is increased from 1.12 to 5.68gl−1 at 25°C when the concentration of AgNO3 is increased from 1 to 5M. Maximum absorption of ethylene is found at near ambient temperatures (15°C). The absorption selectivity of ethylene to ethane increases with increase of AgNO3 concentration and decrease with increasing temperature. The capacity of ethylene absorption in the reactive media at 25°C and 5M concentration of AgNO3 is about 0.43 of that for the aqueous AgNO3 solution. The results of an applied theoretical model for prediction of total ethylene absorption can be verified by the experimental results. [Copyright &y& Elsevier]

Background: Gestational trophoblastic neoplasia (GTN) includes a spectrum of disease ranging from hydatidifrom mole to choriocarcinoma. Low risk GTN is defined as persistent molar pregnancy with a WHO score lower than seven. The optimal chemotherapeutic regimen still remains controversial., Aim: The objectives of this study was to determine efficacy and safety of weekly intramuscular methotrexte in the treatment of low risk gestational trophoblastic neoplasia.(LRGTN) and also identify prognostic factors associated with treatment failure, necessitating second line chemotherapy., Materials and Methods: Sixty-six women with LRGTN from 2001 to 2009 were treated with weekly intramuscular methotrexate at 40 mg/m 2 as first line therapy.Monitoring of treatment was done with weekly checking of βhCG level. Three consecutive negative βhCG measurements showed complete response. After first negative βhCG measurement, one additional dose was administered for consolidation., Results: Of 66 patients, who started the treatment five continued their treatment in other medical centres and were excluded from final analysis for treatment evaluation, and seven discontinued first line therapy because of hepatotoxicity. Of the remaining 54, complete remission occurred in 43 (79.6%) and eleven were resistant to first line therapy. Mean WHO score prior to starting chemotherapy was significantly different between two groups of response and resistance according to our data. Change of treatment to second line Actinomycin-D was necessary in eighteen cases because of resistance to first line in eleven and liver enzyme elevation in seven patients. Sixteen of these 18 responded to Actinomycin-D as second line and one needed hysterectomy for complete response. One patient received multiagent chemotherapy for complete remission., Conclusion: We recommend this effective and safe method of chemotherapy for women with LRGTN. According to our data, lower mean WHO score predicts a better outcome for this regimen.

Objectives: Recurrence of cervical cancer is one of the important and plausible discussions in oncology especially in patients with advanced stages. The purpose of this study was to introduce probability invasive cervical carcinoma recurrence as well as determining characteristics and the prognostic factors of this entity., Methods: A retrospective study was designed to identify risk factors and pattern of uterine cervical carcinoma recurrence evaluating the outcome of 36 registered patients. Recurrence was defined based on clinical or para-clinical documentation over at least 6 months after complete remission following surgery or radiotherapy. Treatment consisted of a radiosurgical combination and exclusive radiotherapy., Results: Mean age in selected patients is 54.8 ± 12.0 years. The pathological reports of primary diagnosis are squamous cell carcinoma in 94.44 % and adenocarcinoma in remaining patients. Mean duration of recurrence among patients is 2.75 ± 1.5 years after the initial treatment. Metrorrhagia is mostly revealing symptom which patients present in recurrent episode. Usually, the recurrence of cervical cancer is presented in pelvic cavity locally. Marginal involvement is documented in 50 % of cases and lymph node in 33.3 % of patients with recurrent episode being involved. Most important prognostic factors are improper treatment (16.66 % of cases) after initial diagnosis., Conclusions: Prognostic factors such as selection of appropriate method for treatment are an important point for reducing the rate of recurrence. Moreover, warning patients about symptoms and frequent episodes of follow up is necessary for early diagnosis of recurrence.
