Therapeutic strategies targeting the DNA damage response, such as poly (ADP-ribose) polymerase (PARP) inhibitors (PARPi), have revolutionized cancer treatment in tumors deficient in homologous recombination (HR). However, overcoming innate and acquired resistance to PARPi remains a significant challenge. Here, we employ a genome-wide CRISPR knockout screen and discover that the depletion of ubiquitin-activating enzyme E1 (UBA1) enhances sensitivity to PARPi in HR-proficient ovarian cancer cells.

The objective of this study was to assess whether the chemotherapy response score predicts homologous recombination status.
Methods: We identified patients with advanced epithelial ovarian cancer (diagnosed January 2019 to 20 June 2023) who received neoadjuvant chemotherapy, underwent interval surgery, and for whom a chemotherapy response score was reported (1=no or minimal tumor response, 2=appreciable tumor response, 3=complete or near complete response with no residual tumor).
Article Synopsis
- This review synthesizes research on uterine-conserving treatments for atypical endometrial hyperplasia and grade 1 endometrial carcinoma while identifying gaps in current knowledge.
- The increasing number of younger patients and those with high surgical risk necessitates effective uterine-conserving options, especially since issues like delayed childbearing and obesity continue to rise.
- Hormonal therapy with close monitoring is the primary conservative method, but more studies are needed to determine the best candidates and tailor treatments based on individual needs.
Article Synopsis
- The study aimed to compare the effectiveness and side effects of two chemotherapy regimens, paclitaxel and carboplatin (PC), against bleomycin, etoposide, and cisplatin (BEP) in treating newly diagnosed or recurrent ovarian sex cord-stromal tumors (SCST).
- In a phase II trial involving 63 patients, the analysis showed that PC did not meet the criteria for being as effective as BEP, with a median progression-free survival of 27.7 months for PC compared to 19.7 months for BEP.
- Although PC had fewer serious adverse events (77% vs. 90%), the study concluded that it failed to demonstrate non-inferiority to BE
Endometrial cancer (EC) is the most common gynaecological cancer among women in high-income countries, with both incidence and mortality continuing to increase. The complexity of the management of patients with EC has evolved with greater comprehension of the underlying biology and heterogeneity of this disease. With a growing number of novel therapeutic agents available, emerging treatment regimens seem to have the potential to help to address the concerning trends in EC-related mortality.
