Background: This study aimed to reveal the clinicopathologic features and causes of bleeding in older patients with postmenopausal bleeding (PMB) and to investigate the correlation between the ultrasonographic findings and etiology of PMB. Methods: We retrospectively analyzed the causes and clinical characteristics of PMB in 498 patients who were diagnosed between January 2007 and December 2017. The population with PMB was divided into 2 groups according to age: Group A (n=204) included individuals more than 65 years of age and group B (n=294) included those less than 65 years of age. Clinical characteristics such as age, parity, underlying conditions, previous surgical history, and previous menopausal hormone therapy were compared between the groups. Cervical cytology testing and transvaginal ultrasonography were performed in all patients with PMB. Endometrial biopsy was performed in all cases of endometrial thickness ${\geq}5mm$. Results: We examined 498 patients with PMB. In group A, atrophic endometrium (n=125, 61.27%) was the most common cause of PMB. Twenty-three patients had gynecological malignancy (cervical cancer: n=12, 5.88%; endometrial cancer: n=8, 3.42%; ovarian cancer: n=3, 1.46%), and 30 patients had benign gynecological disease (endometrial polyp: n=10, 4.90%; submucosal myoma: n=6, 2.94%; uterine prolapse: n=7, 3.42%; cervical dysplasia; n=5, 2.45%; cervical polyp: n=2, 0.98%). Forty patients had endometrial thickness ${\geq}5mm$. Eight patients were diagnosed with endometrial cancer. All cases of endometrial cancer were diagnosed with endometrial thickness >10 mm. Conclusion: Atrophic endometrium was the most common cause of PMB in both groups, and approximately 12% of cases were associated with gynecological malignancy in older patients.

Background: Unopposed estrogen has a central role in development of endometrial benign, premalignant and malignant lesions. The aim of this study was to evaluate the anti-estrogenic effect of metformin on endometrial histology in comparison with progesterone. Materials and Methods: A total of 43 patients who were referred to our center for abnormal uterine bleeding and had a histologic diagnosis were disordered proliferative endometrium or simple endometrial hyperplasia were included and randomly distributed in two groups treated with metformin (500mg Bid) or megestrol (40mg daily), respectively, for three months. After this period the patients were evaluated by another endometrial biopsy to assess the impact of the two drugs in restoring normal endometrial histology. Results: Our findings revealed that metformin could induce endometrial atrophy in 21 out of 22 patients (95.5%) while this positive response was achieved in only 13 out of 21 patients (61.9%) in the megstrol group. In addition two low grade endometrial carcinomas in the metformin group responded very well. Conclusions: We conclude that metformin could be used as an effective antiestrogenic agent in control of abnormal endometrial proliferative disorders.

The laryngeal cancer is a cancer of secondary sex organ, such as malignant tumors of the mammary gland, endometrium, and prostate. The clinical characteristics of the female laryngeal cancers are considered somewhat to be different from that of male. As cancer of the larynx is principally a disease of men, many investigations have showed the characteristics of the male laryngeal cancers. For understanding the clinical characteristics of the female laryngeal cancers, we analyzed 21 cases of laryngeal cancer in women, diagnosed and treated in our institute during the last 10 years. The results were, 1) In female subjects, supraglottis was most common subsite of laryngeal cancer(85.7%). 2) On histopathologic grade, the moderately differentiated squamous cell carcinoma was the most common (80.9%). 3) The positive neck nodes were 19 %, considered to be lower than that of total laryngeal cancer. 4) The treatment results, the 2 year disease free rate and 5 year survival rate were 88.9%, 83.3%, respectively. These results suggest, therefore, female laryngeal cancers are more likely to be supraglottic cancer than glottic cancer. In spite of high incidence of supraglottic cancer, the nodal metastases are rare, the prognosis appeared to be good.

This report is aimed to investigate the effect of Integrative Medicine Therapy (IMT) in treating metastasized ovary and endometrial cancer. A 51-year-old woman who was diagnosed double primary ovarian and endometrial cancer in 2009. The patient was treated with Laparoscopic Assisted Vaginal Hysterectomy (LAVH), Bilateral Salpingo Oophorectomy (BSO) Pelvic Lymph Node Dissection (PLND), adjuvant chemotherapy till Sep. in 2013. But metastases to Rt. External Iliac artery, Aortocaval area Lymph Nodes, Liver(caudate lobe), Rt. Buttock subcutaneous area, Lt. Gastric Area Lymph Nodes were found. Finally, the patient decided to be treated by IMT including Abnoba Viscum, Vitamin C, herbal medication and pharmacopuncture combined with chemotherapy. The efficacy was evaluated with Positron Emission Tomography and Computed Tomography (PET-CT) and Abdomen Computed Tomography (CT). The metastatic tumor in liver was disappeared and Rt. external iliac artery, aortocaval area Lymph Nodes, Rt. buttock subcutaneous area were also decreased after 6 months treatment. These results suggest that IMT may have a potential role for metastatic cancer.

Objective: Endometrial cancer is the fourth most common cancer among women in developed countries. Affected patients may benefit from systemic chemotherapy, alone or in combination with targeted therapies if the disease is clinically diagnosed prior to expansion and metastasis to other organs. The aim of this study was to evaluate the prognostic role of c-kit mutations and comparision with tumor type and grade in human uterine endometrial carcinomas. Materials and Methods: Seventy five patients with endometrial carcinoma and seventy five normal controls were studied for possible mutations in exon 17 of the c-kit gene using single strand conformational polymorphisms and sequencing. Results: c-kit mutation in exon 17 appeared to be significantly different between endometrial carcinoma and normal endometrium. The pattern and frequency of the mutations was also shown to be different between tumors from different stages.

The polycystic ovary syndrome is the most common endocrinological disorder of reproductive age women with a prevalence of 5 to 8 %. The most common diagnostic criteria used for polycystic ovary syndrome are oligo- or an-ovulation, clinical and/ or biochemical signs of hyperandrogenism and polycystic ovaries. Hyperandrogenism results in increased estrogen levels and lack of cyclic progesterone due to anovulation and persistent stimulation of the endometrium may lead to endometrial hyperplasia or adenocarcinoma development. In this mini review, we aimed to evaluate the possible relationship between polycystic ovary syndrome and endometrial cancer.

Objective: To explore the possible significance of aromatase P450 in endometrial hyperplasia with a background of polycystic ovary syndrome (PCOS). Methods: Immunohistochemistry was used to determine the expression of aromatase P450 in endometrium of PCOS patients. Semiquantitative analysis of aromatase P450 expression of mRNA and protein level wasalso carried out by real-time quantitative RT-PCR method. After endometrial cells were stimulated by testosterone and letrozole in vitro, the estradiol ($E_2$) level was determined, and the expression of cell aromatase P450 mRNA was assessed. Results: The aromatase P450 mRNA level was increased in endometria of PCOS patients. When endometrial cells were cultured with $10^{-6}M$ testosterone, the $E_2$ level in the culture medium increased. An inhibitory effect on $E_2$ generation and expression of aromatase P450 mRNA was observed when the endometrial cells were treated with $10^{-5}M$ letrozole. Conclusions: There is an increased expression of aromatase P450 in PCOS patient endometrium. Androgen stimulation could enhance the synthesis of aromatase P450 mRNA and the production of $E_2$ in endometrial cells in vitro while letrozole could do the reverse.
