Objective: To investigate the incidence of malignant transformation and P53 and P16 expression in teratomatous skin of ovarian mature cystic teratoma. Materials and Methods: Data on ovarian teratoma specimens in nearly 10 years were reviewed. P53 and P16 expression were detected by immunohistochemistry in 25 cases of teratomatous skin of ovarian mature cystic teratoma, 20 cases of squamous cell carcinoma and 2 cases of squamous cell carcinoma originated from teratomatous skin. Results: Of 1913 cases of ovarian mature cystic teratoma in nearly 10 years, only two cases of squamous cell carcinoma were found in teratomatous skin, with malignant transformation rate of 0.1045%. P53 expression was detected in 2 cases squamous cell carcinoma originated from teratomatous skin and P16 overexpression in one. There were no expressions of P53 and P16 in 25 cases of teratomatous skin of ovarian mature cystic teratoma. Of 20 cases of squamous cell carcinoma P53 overexpression (positive rate of 55%) was detected in 11 cases, P16 overexpression (positive rate of 35%) in 7 cases. The positive rates of P53 and P16 expression in squamous cell carcinomas were significantly higher than that in the teratomatous skins (p< 0.001, p= 0.002). Conclusions: There was low risk of malignant transformation in teratomatous skin of ovarian mature cystic teratoma which can be explained by lower P53 and P16 expressionin teratomas than that in squamous cell carcinoma.

Introduction: Kelantan is one of the states in Malaysia which has a high prevalence of type 2 diabetes (DM2). Other than with endometrial carcinoma, the association of DM2 with particular female cancers is not known. Objective: To determine the proportion of breast, cervical, ovarian and endometrial cancers among females with DM2 diagnosed in Hospital Universiti Sains Malaysia (HUSM) over an 11 year period. Materials and Methods: All histologically confirmed cases of breast, endometrial, cervical and ovarian carcinomas admitted to the Hospital were included in the study. The patient diabetic status was traced from the hospital medical records. Results: There was a total of 860 cases of breast, cervical, ovarian and endometrial carcinomas over this period. Breast carcinoma was the commonest, accounting for 437/860 (50.8%) followed by cervix, 159/860 (18.5%), ovarian, 143/860 (16.6%) and endometrial carcinomas, 121/860 (14.1%). Out of these, 228/860 (26.5%) were confirmed diabetics. Endometrial carcinoma patients showed the highest proportion being diabetics, 42.1% (51/121), followed by ovarian cancer, 25.9% (37/143), breast carcinoma, 23.6% (103/437) and cervical cancer 23.3% (37/159). Conclusions: There is a significant proportion of DM2 among women with these four cancers, endometrial carcinoma being the highest followed by ovarian, breast and cervical carcinoma. The rising trend of these four cancers is in tandem with an increasing trend of DM2 in the community. In populations where diabetes is prevalent, screening for epithelial cancers should be rigourous. Diabetic clinics should include screening for these cancers among their female patients and gynecology clinics should screen the women they treat for their diabetes status.

Objectives: To determine the prevalence and predicting factors of ovarian metastasis, and evaluate the histology of other ovarian neoplasms in women with early-stage cervical cancer. Methods: The medical records of women with cervical cancer stage IA-IIA who underwent primary surgical treatment at Siriraj Hospital, Mahidol University from January 2007 to December 2011 were used for the study. Demographic, clinical and histopathologic data of the women who underwent salpingo-oophorectomy were reviewed. Results: Of 264 women, the mean age was 52.3 years. The types of hysterectomy procedures were composed of 210 radical hysterectomy, 9 modified radical hysterectomy, 40 simple hysterectomy, and 5 abandoned hysterectomy. The prevalence of ovarian metastasis was 0.76% (2/264). All of ovarian metastatic patients were older than 60 years old, postmenopause, and had macroscopical stage IB1 cervical cancer. Others ovarian tumors were found in 7 patients including 1 synchronous ovarian carcinoma, 1 serous cystadenoma, 1 fibroma, and 4 teratoma. Conclusions: In cases of early-stage cervical carcinoma of the population studied, ovarian preservation could be another option in <60-year-old patients, with non-neuroendocrine cell type, stage IA, and no extracervical or ovarian lesions.

Background: Ovarian mucinous carcinoma has a poor prognosis in advanced stages and a poor response to conventional chemotherapy. An efficient treatment is not yet available. We heere investigated HER2 expression and the potential for trastuzumab therapy in ovarian mucinous tumors. Materials and Methods: Immunohistochemistry was performed in formalin-fixed, paraffin-embedded tissue from 27 ovarian mucinous tumors including 14 carcinomas and 13 borderline tumors diagnosed in the Pathology Department, Farhet Hached Hospital, Sousse, between 1993 and 2013. The HercepTest (DAKO) was used for immunohistochemistry. Results: HER2 expression was observed in only one borderline tumor (7.7%) and in 14.3% of mucinous carcinomas of the ovary. Conclusions: Our results suggest that trastuzumab therapy would be an option for patients with mucinous carcinoma when the tumor has HER2 overexpression.

Lobaplatin, one of the third - generation platinum compounds, has shown encouraging anticancer activity in a variety of tumor types. However, the efficacy of lobaplatin in ovarian cancer has not been systemically evaluated. In this study, lobaplatin as a single agent and in combination with taxanes was investigated in - vitro and in an in vitro model of ovarian carcinoma. Using the sulforhodamine B (SRB) assay, the cytotoxic effects of lobaplatin alone and in combination with taxanes were compared with cisplatin and carboplatin in seven ovarian cancer cell lines. In addition, in - vitro antitumor activities were evaluated with cisplatin - sensitive and cisplatin - resistant human ovarian cancer xenografts in nude mice. The cytotoxicity of lobaplatin was similar to or higher than that of cisplatin and carboplatin, with $IC_{50}$ values from 0.9 to $13.8{\mu}mol/L$ in a variety of ovarian cancer cells. The combination of lobaplatin with docetaxel yielded enhanced cytotoxic activity in vitro. In addition, in platinum - sensitive ovarian cancer xenografts, lobaplatin alone showed similar antitumor activity to cisplatin and carboplatin. Furthermore, lobaplatin alone or in combination with docetaxel exhibited significant activity in platinum - resistant ovarian cancer xenografts. These results indicate that the use of lobaplatin alone or in combination with docetaxel might be a rational and novel therapeutic strategy for ovarian cancer. Further clinical development of lobaplatin is clearly warranted.

Objectives: We designed this study to evaluate the effect of Korean medical treatment on complications of chemotherapy after curative resection in patient with ovarian carcinoma IV. Methods: The patient got total abdominal hysterectomy and bilateral salpingo-oophorectomy (TAHBSO) on 9/4 and received chemotherapy on 10/7, 10/28, 11/18. During this period, the patient suffered from anorexia, dyspepsia, nausea, weight loss and insomnia. We treated the patient with herbal medicine and acupuncture. The efficacy of treatment was evaluated with visual analog scale (Vas), weight and 36-item short form health survey instrument (SF-36). Results: After treatment, although the scale values went ups and downs according to chemotherapy schedule, abdominal pain Vas changed 7 to 0, weight changed 46 kg to 51 kg. Also, SF-36 scores increased. Conclusions: This case report shows that the Korean medical treatment is useful in the treatment of complications of chemotherapy after curative resection in patient with ovarian carcinoma IV.

High-grade serous carcinoma (HGSC) is the most common type of pelvic cancer among women. Serous tubal intraepithelial carcinoma (STIC) is a precursor lesion of HGSC. Herein, we report a rare occurrence of STIC in patients undergoing surgery for benign indications without a family history of ovarian cancer. A 77-year-old woman underwent total laparoscopic hysterectomy and bilateral salpingo-oophorectomy for uterine prolapse. Pathological examination revealed bilateral STIC without ovarian abnormalities, and no other abnormal findings were noted. Another patient, a 49-year-old woman, underwent laparoscopic total hysterectomy and bilateral salpingectomy for uterine fibroids. STIC lesions were observed in both fallopian tubes. Subsequently, a staging was performed. No additional lesions were found, and the patient was followedup through imaging and blood tests. As reports of STIC lesions are rare, data on their clinical outcomes and management strategies are limited. In this report, we present cases of incidental STIC in benign surgery and discuss its proper interpretation and management. Through the early detection of STIC lesions, patients with risk factors can be identified in advance, which will allow prevention and early detection of ovarian cancer. Opportunistic salpingectomy was also actively discussed in this regard.

Tracheal tumors are uncommon comprising less than 0.1% of all malignancies. Metastatic tracheal tumors, especially from the extrathoracic sites, are exceedingly rare. Ovarian cancer tends to metastasize to the serous cavities and the lymph nodes. One large autopsy study reported tracheal involvement in 1% of patients who had died from ovarian cancer. Other studies have not mentioned tracheal involvement at all. Since the main symptoms of cough, hemoptysis, or wheezing are nonspecific, patients may be initially treated for other conditions including asthma or bronchitis. Here we describe a metastatic tracheal tumor from an ovarian carcinoma that was initially treated for bronchial asthma.

Purpose: To evaluate the prognostic impact of peritoneal washing cytology in patients with endometrial and ovarian cancers. Materials and Methods: We retrospectively identified 86 individuals with ovarian carcinomas, ovarian borderline tumors and endometrial adenocarcinomas. The patients had been treated at Shahid Sadoughi Hospital and Ramazanzadeh Radiotherapy Center, Yazd, Iran between 2004 and 2012. Survival differences were determined by Kaplan-Meier analysis. Multivariate analysis was performed using the Cox regression method. A p<0.05 value was considered statistically significant. Results: There were 36 patients with ovarian carcinomas, 4 with borderline ovarian tumors and 46 with endometrial carcinomas. The mean age of the patients was $53.8{\pm}15.2years$. In patients with ovarian carcinoma the overall survival in the negative cytology group was better than the patients with positive cytology although this difference failed to reach statistical significance (p=0.30). At 0 to 50 months the overall survival was better in patients with endometrial adenocarcinoma and negative cytology than the patients with positive cytology but then it decreased (p=0.85). At 15 to 60 months patients with FIGO 2009 stage IA-II endometrial andocarcinoma and negative peritoneal cytology had a superior survival rate compared to 1988 IIIA and positive cytology only, although this difference failed to reach statistical significance(p=0.94). Multivariate analysis using Cox proportional hazards model showed that stage and peritoneal cytology were predictors of death. Conclusions: Our results show good correlation of peritoneal cytology with prognosis in patients with ovarian carcinoma. In endometrial carcinoma it had prognostic importance. Additional research is warranted.

Mature cystic teratoma is a common ovarian lesion, approximately 10-20% of ovarian tumor. However, it can undergo a malignant transformation, but incidence of malignant transformation is very low. Squamous cell carcinoma is the most common type of malignant transformation in the mature cystic teratoma. Preoperative diagnosis of malignant transformation in the mature cystic teratoma is very difficult, because malignant transformed tissues are very small in the mature cystic teratoma components. And so most of the carcinoma arising in mature cystic teratoma were diagnosed after histologic examination. We experienced a case of squamous cell carcinoma arising in the mature cystic teratoma of the ovary and report a case with a brief review of the literatures.
