Objective: It is well known that ovarian steroids modulate bone turnover. Conditions associated with low levels of these hormones, such as menopause, hypogonadism, and others, have been related to osteopenia or osteoporosis. On the other hand, hyperandrogenism in premenopausal women, mainly in polycystic ovarian syndrome, has been reported to have a protective effect on bone mass. However, data regarding how bone mass is affected by neoformative processes in which steroids are increased are not as well documented. Our aim was to study the effect of secreting ovarian tumors on bone mass.
Methods: A total of 14 patients were referred to our hospital because of endocrine ovarian tumors. Steroid levels were measured prior to and after surgery. Bone mineral density (BMD) by DEXA was assessed at inclusion in all cases. Additionally, in 7 women bone measurement was repeated after 1-year follow-up. The setting was a tertiary hospital.
Results: All patients showed increased levels of testosterone, androstenedione, and free testosterone prior to surgery. BMD was also in the normal-upper range or over normal in all of them. As expected in the subjects with a second DEXA a decrease in bone mass was noted.
Conclusion: Steroid secreting ovarian tumors increase bone mass and thus may protect women from later osteoporosis.

Purpose: Hereditary breast and ovarian cancers (HBOC) carry a high risk of breast cancer, and detailed screening with contrast-enhanced breast MRI (breast MRI surveillance) is recommended. With the increase in the number of individuals diagnosed with HBOC, the demand for breast MRI surveillance is also rising. However, the current system is inadequate, with factors such as lack of knowledge and indifference among healthcare professionals, and insufficient understanding of breast MRI surveillance being cited.

Background: The pathogenesis of ovarian cancer (OvCa) involves a complex interplay of genetic, environmental, and hormonal factors. With the in-depth exploration of tumor ecosystem, exosomes can mediate the immunological status of tumor microenvironment (TME). Therefore, we aimed to recognize the tumor-derived exosomes (TEXs) which can distinguish the immune-hot and cold tumors and reflect the immunotherapeutic responses.

Background: Ovarian cancer (OC), particularly high-grade serous ovarian carcinoma (HGSOC), is the leading cause of mortality from gynecological malignancies worldwide. Despite the initial effectiveness of treatment, acquired resistance to poly(ADP-ribose) polymerase inhibitors (PARPis) represents a major challenge for the clinical management of HGSOC, highlighting the necessity for the development of novel therapeutic strategies. This study investigated the role of 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 3 (PFKFB3), a pivotal regulator of glycolysis, in PARPi resistance and explored its potential as a therapeutic target to overcome PARPi resistance.

Background: Ovarian cancers (OC) and cervical cancers (CC) have poor survival rates. Tumor-infiltrating lymphocytes (TILs) play a pivotal role in prognosis, but shared immune mechanisms remain elusive.
Methods: We integrated single-cell RNA sequencing (scRNA-seq) and spatial transcriptomics (ST) to explore immune regulation in OC and CC, focusing on the PI3K/AKT pathway and FLT3 as key modulators.
Personality traits of women with hereditary risk for breast/ovarian cancer versus obstetric history and cancer preventive behaviors.

The aim of the study is to analyze the relationship between personality traits of women with hereditary predisposition to breast/ovarian cancer and their obstetric history and cancer-preventive behaviors. A total of 357 women, participants of 'The National Program for Families With Genetic/Familial High Risk for Cancer', were included in the study. The Neo Five-Factor Inventory (NEO-FFI) and a standardized original questionnaire designed for the purpose of the study were used.
