Prognostic impact of intraoperative rupture in early-stage epithelial ovarian cancer: an ancillary study of GORILLA-3002

To evaluate whether intraoperative rupture affects oncological outcomes in patients with early-stage epithelial ovarian cancer (EOC). A multicenter retrospective study was conducted on patients with early-stage EOC based on surgical and final pathological reports between 2007 and 2021. Oncologic outcomes were compared between the unruptured group (International Federation of Gynaecology and Obstetrics [FIGO] stage IA/IB) and ruptured group (FIGO stage IC1). The primary endpoint was progression-free survival (PFS). Propensity score matching (PSM) was performed to adjust for the imbalance in prognostic factors between the groups. Overall, 197 (58.3 %) patients comprised the unruptured group (FIGO stage IA/IB), and 141 (41.7 %) were in the intraoperatively ruptured group (FIGO stage IC1). No significant difference in the 5-year PFS was observed between the two groups before PSM (92.65 % vs. 92.80 %, P = 0.93). After PSM, the 5-year PFS showed a noticeable decrease in the ruptured group compared to the unruptured group, although this difference showed borderline statistical significance (96.90 % vs. 89.82 %, P = 0.061). This trend was particularly discernible in cases with aggressive tumor characteristics; intraoperative rupture remained an independent prognostic factor for shorter PFS in patients with high-grade histology (adjusted hazard ratio = 14.4, 95 % confidence interval = 2.8-74.1). Although not statistically significant, intraoperative rupture may negatively affect PFS in these patients after PSM. Therefore, rupture during surgery should be avoided as it can cause upstaging and unnecessary chemotherapy.

Major clinical research advances in gynecologic cancer in 2023: a tumultuous year for endometrial cancer

In the 2023 series, we summarized the major clinical research advances in gynecologic oncology based on communications at the conference of Asian Society of Gynecologic Oncology Review Course. The review consisted of 1) Endometrial cancer: immune checkpoint inhibitor, antibody drug conjugates (ADCs), selective inhibitor of nuclear export, CDK4/6 inhibitors WEE1 inhibitor, poly (ADP-ribose) polymerase (PARP) inhibitors. 2) Cervical cancer: surgery in low-risk early-stage cervical cancer, therapy for locally advanced stage and advanced, metastatic, or recurrent setting; and 3) Ovarian cancer: immunotherapy, triplet therapies using immune checkpoint inhibitors along with antiangiogenic agents and PARP inhibitors, and ADCs. In 2023, the field of endometrial cancer treatment witnessed a landmark year, marked by several practice-changing outcomes with immune checkpoint inhibitors and the reliable efficacy of PARP inhibitors and ADCs.
