Two part collectives of patients with carcinomas of the uterus - one consisting of 525 conventionally irradiated patients, the other consisting of 577 patients irradiated with telecobalt - are compared with respect to their five-year survival recovery rate, the frequency of recurrences and metastases and the radiogenic complications. After having introduced the telecobalt therapy - intracavitary radium therapy remaining unchanged - the five-year survival recovery ameliorated by about 10% for carcinomas of the cervix as well as for carcinomas of the body of the uterus. The evaluation according to tumor stages showed that the telecobalt irradiation was particularly advantageous for operated and non-operated patients with a carcinoma of the cervix of stage II as well as for non-operated patients with a carcinoma of the body of the uterus. The authors discuss the possible reasons for the increase of recurrence rate and radiogenic complications observed in patients treated with telecobalt.

Tamoxifen, a common adjuvant therapy for hormone receptor-positive breast cancer, is associated with an increased risk of endometrial pathologies, such as hyperplasia, polyps, and carcinoma. This study investigates rapamycin, an mTOR inhibitor, as a potential novel strategy for preventing tamoxifen-induced endometrial proliferation. This in vitro study utilised endometrial stromal cells isolated from infertile women.

Mesonephric-like adenocarcinoma (MLA) is a newly recognized type of carcinoma that occurs in the uterus and ovaries. MLA exhibits distinct morphological and immunophenotypical features similar to those of mesonephric carcinoma of the cervix or vagina, with the majority of reported tumors containing mutations. MLA is exceedingly rare and appears to be associated with aggressive clinical behavior.

Objective: To examine the diagnostic efficacy of contrast-enhanced ultrasound (CEUS) with Sonazoid (Sonazoid-CEUS) for endometrial lesions.
Methods: In this prospective and multicenter study, data were collected from 84 patients with endometrial lesions from 11 hospitals in China. All the patients received a conventional US and Sonazoid-CEUS examination.

This study investigated the risk factors for endometrial hyperplasia (EH) and endometrial carcinoma (EC) in premenopausal women. The goal was to establish a nomogram model to predict the risk of EH/EC and quantitative standards in clinical practice, which improved the clinical prognosis of EH/EC patients. Data were collected from premenopausal women with suspected EH/EC who underwent hysteroscopic endometrial biopsy.

Article Synopsis
- Uterine carcinosarcoma (UCS) is a rare cancer combining both carcinoma and sarcoma features, often resembling endometrial carcinoma, with a potential link to nulliparity (never having given birth) as a risk factor.
- A 55-year-old woman presented with postmenopausal vaginal bleeding and was diagnosed after surgery, revealing well-differentiated adenocarcinoma and osteosarcoma components, along with multiple positive immunohistochemical markers.
- Following a series of surgical interventions and treatments, including chemotherapy and radiotherapy, the patient demonstrated no signs of tumor recurrence and had a disease-free survival of seven months as of July 2024.
