Introduction: Radioactive iodine (RAI) ablation treatment is used for patients diagnosed with well-differentiated thyroid cancer in order to reduce the risk of recurrence. RAI ablation treatment can adversely affect gonads in males and females. In this study, we aimed to determine ovary damage and infertility risk due to RAI, using serum anti-Müllerian hormone (AMH) level, in females who received RAI ablation treatment. Materials and Methods: 45 female patients who have not gone through the menopause and had received RAI ablation treatment for well-differentiated thyroid cancer in premenopausal period, and 40 healthy females as control groups were included in this study...

During testicular maturation, both Sertoli cells (SCs) and germ cells (GCs) switch from an immature to a mature immunophenotype. The reexpression of markers of immaturity in adults has been reported in cancer and in other testicular pathologies, in men as well as in animal species. Naturally affected with testicular cancer, rabbits have long been used in human reproductive research, but reports on the expression of testicular cell markers in this species are few and data about the immunophenotype of normal postnatal SCs and GCs are lacking...

Anal cancer was diagnosed in a 36-year-old nulliparous woman. Before chemoradiation was started, ovarian transposition and uterine fixation were performed in order to preserve capability for future parenthood. Despite of a low anti-Mullerian hormone level, IVF therapy was successful and resulted in a full-term delivery of a healthy baby by cesarean section. This is the first case report of successful pregnancy after full-dose pelvic radiation for anal cancer.

STUDY QUESTION: Which factors related to patient, treatment or disease are associated with ovarian function recovery after chemotherapy in premenopausal women with breast cancer? SUMMARY ANSWER: Younger age and GnRH agonist (GnRHa) administration during chemotherapy were significantly associated with menses recovery, but this recovery was less likely in patients exposed to taxanes. WHAT IS ALREADY KNOWN: To date, published meta-analyses have only assessed GnRHa administration as a possible factor for ovarian function recovery, and their results were conflicting...

STUDY OBJECTIVE: Preliminary data on the effects of prophylactic bilateral salpingectomy (PBS) show that postoperative ovarian function is preserved up to 3 months after surgery. The confirmation of PBS safety on ovarian function even many years after surgery is essential to reassure the medical community that this new strategy, recently proposed for the prevention of ovarian cancer, is at least able to avoid the risk of premature surgical menopause. We investigated whether the addition of PBS during total laparoscopic hysterectomy (TLH) causes long-term effects on ovarian function...

Regulation of lineage-restricted transcription factors has been shown to influence malignant transformation in several types of cancer. Whether similar mechanisms are involved in ovarian cancer pathogenesis is unknown. PAX8 is a nuclear transcription factor that controls the embryologic development of the Müllerian system, including the fallopian tubes. Recent studies have shown that fallopian tube secretory epithelial cells (FTSECs) give rise to the most common form of ovarian cancer, high-grade serous ovarian carcinomas (HGSOCs)...

Endometrial cancer is the most common gynecologic malignancy in developed countries. Clear cell carcinoma typically occurs in the ovaries, and very rarely occurs in the endometrium; it accounts for less than 3% of all endometrial cancers. It is presumed that clear cell carcinomas are of Müllerian duct origin, and an association with exposure to diethylstilbestrol (DES) or other nonsteroidal follicle stimulating hormones has been described. We report a case of a postmenopausal woman who presented with vaginal bleeding without a specific medical history...

A fundamental understanding of prostate development and tissue homeostasis has the high potential to reveal mechanisms for prostate disease initiation and identify novel therapeutic approaches for disease prevention and treatment. Our current understanding of prostate lineage specification stems from the use of developmental model systems that rely upon the embryonic preprostatic urogenital sinus mesenchyme to induce the formation of mature prostate epithelial cells. It is unclear, however, how the urogenital sinus epithelium can derive both adult urethral glands and prostate epithelia...

This selection from the NCCN Guidelines for Ovarian Cancer focuses on the less common ovarian histopathologies (LCOHs), because new algorithms were added for LCOHs and current algorithms were revised for the 2016 update. The new LCOHs algorithms include clear cell carcinomas, mucinous carcinomas, and grade 1 (low-grade) serous carcinomas/endometrioid epithelial carcinomas. The LCOHs also include carcinosarcomas (malignant mixed Müllerian tumors of the ovary), borderline epithelial tumors (also known as low malignant potential tumors), malignant sex cord-stromal tumors, and malignant germ cell tumors...

Endometrioid carcinoma (EC) is a relatively indolent ovarian carcinoma subtype that is nonetheless deadly if detected late. Existing genetically engineered mouse models (GEMMs) of the disease, based on transformation of ovarian surface epithelium (OSE), take advantage of known ovarian EC driver gene lesions but do not fully recapitulate disease features seen in patients. An EC model in which the Apc and Pten tumour suppressor genes are conditionally deleted in murine OSE yields tumours that are biologically more aggressive and significantly less differentiated than human ECs...

We prospectively investigated anti-Müllerian hormone (AMH) as a measure of ovarian insult in young females during and after treatment for Wilms tumor (WT), osteosarcoma (OS), and Ewing sarcoma (ES).Twenty-one female childhood cancer patients, with a mean age of 7.9 years (range 0.6-17), entered the study. Levels of AMH, follicle-stimulating hormone (FSH), and luteinizing hormone were monitored at diagnosis and every 3 to 4 months during, and regularly for a mean of 2.6 years after treatment.A profound decline in AMH was seen in the majority of the 21 study patients 3 to 4 months after the beginning of treatment, the exception being patients with WT, of whom 60% showed no such decline...

PURPOSE: Mutations in the BRCA1/2 genes are associated with breast and ovarian cancer susceptibility. Recent studies have suggested that the BRCA mutation might be associated with occult primary ovarian insufficiency. To evaluate fertility, several studies have validated anti-Mullerian hormone (AMH) as a direct biomarker for ovarian aging and it is considered a quantitative marker of ovarian reserve. We hypothesize that BRCA1 gene mutations will be negatively associated with AMH levels...

Persistent Müllerian duct syndrome (PMDS) is a condition in which a 46, XY male displays masculine external genitalia, but internally retains developed Müllerian duct structures (uterus, fallopian tubes, and upper two-thirds vagina). Thoughtful operative consideration is needed to maximize the therapeutic benefit while minimizing the risk of hypogonadism, infertility, and erectile dysfunction. We report a 53-year-old male with a pelvic mass incidentally discovered on routine ultrasound, intra-operatively discovered to be PMDS...

Cyclophosphamide (CP), the commonly used chemotherapeutic agent in cancer treatment, is proven to cause ovarian toxicity and infertility in women. In the present study, we investigated the protective effect of genistein (GEN), a phytoestrogen found in the soy protein, against CP-induced ovarian toxicity in rats. Forty female adult rats were allocated into five groups. A normal control group received the vehicle; another group was injected with a single acute intraperitoneal dose of CP (200mg/kg). Three other groups were pretreated with GEN (0...

Opportunities for patients undergoing hemodialysis to receive chemotherapy are increasing. A combination of paclitaxel and carboplatin (TC) is first-line chemotherapy in patients with Müllerian cancer. However, the optimal dose and time interval between the end of carboplatin administration and initiation of hemodialysis remains to be elucidated. TC was administered to a patient with fallopian tube cancer undergoing hemodialysis. The paclitaxel regimen was determined to be 135 mg/m(2) (total of 210 mg) over 3 h...

Granulosa cell tumor of the ovary is a rare, hormonally active ovarian cancer, typical symptoms of which include various gynecological bleeding disorders. Adult granulosa cell tumor is most commonly detected at stage I, whereupon the prognosis is good. The disease, however, recurs in one third of stage I patients and leads to death in half of these. Conventional cytotoxic agents may be ineffective in the treatment of relapsed tumors. Inhibin B and anti-Müllerian hormone have proven to be sensitive and accurate markers...

Anti-Müllerian hormone (AMH) and its type II receptor AMHR2, both previously thought to primarily function in gonadal tissue, were unexpectedly identified as potent regulators of transforming growth factor (TGF-β)/bone morphogenetic protein (BMP) signaling and epithelial-mesenchymal transition (EMT) in lung cancer. AMH is a TGF-β/BMP superfamily member, and AMHR2 heterodimerizes with type I receptors (ALK2, ALK3) also used by the type II receptor for BMP (BMPR2). AMH signaling regulates expression of BMPR2, ALK2, and ALK3, supports protein kinase B-nuclear factor κB (AKT-NF-κB) and SMAD survival signaling, and influences BMP-dependent signaling in non-small cell lung cancer (NSCLC)...

The diagnosis and treatment of a patient with Mullerian duct cyst torsion combined with bladder cancer were retrospectively analyzed. The patient received an open abdominal operation with right accessory resection plus pelvic adhesion release, and conducted microscopic examination for the bladder under general anesthesia. The results of histopathological examination confirmed the diagnosis of Mullerian duct cyst and papillary urothelial carcinoma at low level. After surgery, the patient received chemotherapy and follow-up observation, and all the indices for the patient were normal and no obvious discomfort...

Sister Mary Joseph's nodule is sometimes the first sign of an internal malignancy, including gastrointestinal, gynecological, or malignancy of unknown primary. It is rarely the sole presentation of a primary peritoneal cancer. In this report, we present the case of a 70-year-old female with umbilical drainage and a computed tomography scan consistent with solitary umbilical nodule. Excision of the nodule revealed adenocarcinoma of likely müllerian origin. Surgical staging did not show any evidence of malignancy with the exception of pelvic washings...

Women with Lynch syndrome (LS) have a high risk of developing endometrial carcinoma (EC) and, less frequently, ovarian carcinoma. As EC not uncommonly is the first malignancy, prophylactic hysterectomy (PH) has been increasingly implemented. In this study, we report the clinicopathologic features of a series of 70 LS patients who underwent either PH (n=39) or nonprophylactic hysterectomy (NPH) (n=31) at 3 tertiary referral centers. Among the 39 patients with PH, 2 had endometrial tumors seen grossly, whereas 37 showed no macroscopic lesions...
