The Polycystic Ovary Disease (PCOD) is one of the most common endocrine disorders in women with a prevalence of 5%. Affected women often consult a gynecologist because of menstrual irregularities, fertility problems or problems of androgen excess. However, PCOD is a metabolic disorder affecting multiple organs. Studies suggest that those women are at risk for developing several complications such as type II diabetes mellitus, hypertension, dyslipidemia and myocardial infarction. The risk to develop endometrial carcinoma is also elevated. To give adequate treatment to women with PCOD, an interdisciplinary approach of gynecologists together with endocrinologists specialized in metabolic and nutritional disorders at the University of Basel is presented. The work-up for diagnosis and assessment of risk factors is outlined. Goal of this interdisciplinary approach is an adequate evaluation of affected patients and their long-term follow-up to test if proposed interventions as weight loss, treatment of hyperinsulinemia, regulation of menstrual cycle and others can avoid long-term sequelae.

A single gene encodes the key enzyme for estrogen biosynthesis termed aromatase, inhibition of which effectively eliminates estrogen production. Aromatase inhibitors successfully treat breast cancer and endometriosis, whereas their roles in endometrial cancer, uterine fibroids, and aromatase excess syndrome are less clear. Ovary, testis, adipose tissue, skin, hypothalamus, and placenta express aromatase normally, whereas breast and endometrial cancers, endometriosis, and uterine fibroids overexpress aromatase and produce local estrogen that exerts paracrine and intracrine effects. Tissue-specific promoters distributed over a 93-kilobase regulatory region upstream of a common coding region alternatively control aromatase expression. A distinct set of transcription factors regulates each promoter in a signaling pathway- and tissue-specific manner. Three mechanisms are responsible for aromatase overexpression in a pathologic tissue versus its normal counterpart. First, cellular composition is altered to increase aromatase-expressing cell types that use distinct promoters (breast cancer). Second, molecular alterations in stromal cells favor binding of transcriptional enhancers versus inhibitors to a normally quiescent aromatase promoter and initiate transcription (breast/endometrial cancer, endometriosis, and uterine fibroids). Third, heterozygous mutations, which cause the aromatase coding region to lie adjacent to constitutively active cryptic promoters that normally transcribe other genes, result in excessive estrogen formation owing to the overexpression of aromatase in many tissues.

Transitional cell carcinoma is a very rare histological subtype of endometrial cancer, with only 18 cases described in literature. Ovary represents the most common site where it accounts for 2% of all ovarian cancers. Due to the rarity of this disease, current management is controversial and includes various approaches, mostly described in the adjuvant setting, both radiotherapy and chemotherapy alone or in combination. Here, we report a case of a 65-year-old patient who underwent adjuvant vaginal brachytherapy for an endometrial transitional cell carcinoma. The patient was treated with radical total abdominal hysterectomy and bilateral salpingo-oophorectomy (TAH-BSO), without lymph-node sampling, and adjuvant endocavitary brachytherapy delivering 30 Gy in 5 fractions in consecutive days. Treatment tolerance was excellent, with only G1 genitourinary acute toxicity and no other adverse events reported. In this experience, the choice of brachytherapy alone resulted in excellent local control outcomes. However, the patient developed a distant recurrence after 43 months and chemotherapy was applied. More research is required to determine the most effective treatment for this rare histological subtype, and in particular, the role of chemotherapy and radiotherapy combinations.
