Article Synopsis
  • The study compared the combination of lenvatinib and pembrolizumab (len + pembro) with traditional chemotherapy for advanced or recurrent endometrial cancer (aEC) in patients who had not previously been treated.
  • Results showed that while len + pembro did not statistically outperform chemotherapy in terms of progression-free survival (PFS) or overall survival (OS), it offered similar outcomes, indicating noninferiority.
  • The trial involved 842 patients and found median PFS and OS were comparable between the two treatment groups, suggesting len + pembro could be an effective alternative to chemotherapy for this cancer type.

In fertility-sparing management (FSM), two different issues can be distinguished: the risk of recurrence/death and the chance of childbearing. Survival is the principal outcome in oncology, and definitions of overall survival and progression-free survival are therefore well defined and widely accepted. The introduction of FSM to clinical practice was determined by the desire of young cancer patients to still have children.

Article Synopsis
  • Surgery is crucial for treating ovarian and endometrial cancer, and the European Society of Gynecological Oncology has set quality indicators to ensure high standards of care.
  • An analysis of surgical management data from the National Health Fund from 2017-2020 showed that most surgeries were performed in departments that fell short of the recommended annual volume benchmarks, indicating a decentralized approach to surgical treatment.
  • The study observed a general increase in surgeries until 2019, followed by a decline in 2020 likely due to the COVID-19 pandemic impacting cancer management.

Article Synopsis
  • The cervical microbiome (CM) is affected by gynecological cancers and undergoes changes after chemoradiation (CRT) therapy in cervical cancer patients.
  • A study analyzed cervical swabs from 16 cervical cancer patients and 30 healthy women, revealing significant differences in microbiome composition before and after treatment.
  • The findings indicate that the CM is more diverse in pre-treatment cancer patients compared to healthy controls, and major alterations occur post-CRT, suggesting potential avenues for future research on treatment options.

Several hundred million people are infected with genital genotypes of the human papillomavirus (HPV) annually in the world. The infections transmitted mainly through sexual routes are usually asymptomatic, but can lead to the development of cervical, vulvar, vaginal, anal, penile cancers, some head and neck cancers and genital warts (condylomas). The fraction HPV-related cancers range from nearly 100% in the case of cervical cancer to several/over a dozen percent in the case of other cancers and diseases.

For many years endometrial cancer has been subdivided into oestrogen - dependent (type I) and oestrogen - independent (type II), according to classical Bokhman classification. Histopathological evaluation including type and grade of tumour, along with clinical factors have been considered as very important prognostic factors that impact treatment decision. However, histologically similar tumours may have different outcomes.

Aims: Vulvar squamous cell carcinoma (VSCC) spreads early and mainly locally direct expansion into adjacent structures, followed by lymphatic metastasis to the regional lymph nodes (LNs). In the lymphatic metastasis, cancer cells bearing CXCR4 and ACKR3 (CXCR7) receptors are recruited to the LNs that produce the CXCL12 ligand. Our study aimed to assess the role of the CXCR4/ACKR3/CXCL12 axis in VSCC progression.
