Laterally extended endopelvic resection (LEER) is a surgical option for patients with laterally recurrent gynecological malignancies to preserve sciatic nerve function [1]. However, when a laterally recurrent tumor involves the sacrum, debulking surgery is generally abandoned because the surgical excision line is outside the standard LEER. Since its technical feasibility and oncological safety have been demonstrated, sacrectomy for recurrent rectal cancer is now considered the treatment of choice [2]. Theoretically, if complete resection is deemed possible, LEER and sacrectomy (beyond-LEER) may be the treatments of choice for recurrent gynecological malignancies. However, the technical feasibility of beyond-LEER has not been reported. In this video, we demonstrate the step-by-step procedure of laparoscopy-assisted beyond-LEER in a patient with platinum-sensitive recurrent ovarian cancer. The patient, with stage IVA ovarian cancer, was in complete remission after debulking surgery and chemotherapy. At the 13-month-platinum-free interval, a solitary recurrent tumor, involving the right internal iliac vessels and infiltrating the right sacral foramen (S3), was detected. Thus, second-line chemotherapy was initially introduced. During 6 months of chemotherapy, the tumor size remained unchanged and no other metastatic lesions were detected. Therefore, surgical resection was planned. Laparoscopy-assisted beyond-LEER was performed, and complete resection without tumor exposure was accomplished. No sign of recurrence 9 months post debulking surgery has been noted. This is the first report to demonstrate the technical feasibility of laparoscopy-assisted beyond-LEER. Table 1 presents a comparison with cases wherein open total pelvic exenteration with low-sacrectomy (TPES) was performed for recurrent rectal cancer. Forty-nine cases of open TPES demonstrated operation time, 11.5 hours; blood loss volume, 2,630 mL; and length of stay, 24.5 days [3]. These results are similar to the findings in our case: operation time, 11 hours; blood loss volume, 1,700 mL; and length of stay, 35 days. We suggest that the benefit of laparoscopy cannot be demonstrated because TPES is a different procedure compared with the beyond LEER. Kimura et al. [4] demonstrated that laparoscopic TPES for recurrent rectal cancer might have a benefit of reduced blood loss. The advantages of laparoscopy during our multidirectional procedure include not only the possibility of reducing blood loss but also the quick closure of abdominal wound and ease of keeping wound clean while changing patient's position during sacrectomy. However, due to the limited case and follow up periods, further studies are required to determine the efficacy of this novel surgery and real advantage of laparoscopy. The informed consent for use of this video was taken from the patient.

Informed consent is a fundamental aspect of surgical care, designed to reinforce patient autonomy, promote shared decision-making, and potentially mitigate legal conflicts by ensuring the provision of comprehensive and consistent information in clinical practice. The Korean Society of Gynecologic Oncology (KSGO) previously published detailed informed consent documents for cervical, endometrial, and ovarian cancer surgery. However, standardized consent forms remain relatively lacking for laparoscopic-robotic hysterectomy performed for non-malignant indications, as well as for vulvar cancer surgery. Hence, the KSGO subcommittee collected, reviewed, and discussed consent forms from domestic medical institutions and subsequently developed informed consent for laparoscopic-robotic hysterectomy and vulvar cancer surgery, aiming to build patient trust and understanding.

Objective: Uterine cancer (UC) is a major cause of cancer-related deaths among women. This study assesses the global burden of UC from 1990 to 2021.

Methods: Data from the Global Burden of Disease 2021 study were used to analyze UC incidence, mortality, and disability-adjusted life years (DALYs) across 204 countries. Age-standardized rates were evaluated by age and Socio-Demographic Index (SDI), with trends forecasted to 2036 using Bayesian models.

Results: In 2021, the global incidence of UC reached 473,614 cases (95% uncertainty interval [UI]=4,29916-5,13667), with an age-standardized incidence rate of 5.41 per 100,000 (95% UI=4.90-5.87), showing an upward trend since 1990, particularly in high-SDI regions. However, the mortality rate in high SDI regions exhibited a declining trend, with an estimated annual percentage change (EAPC) of -0.25 (95% confidence interval=-0.42 to -0.08). Although the number of deaths globally has increased, the age-standardized mortality rate has decreased compared to 1990 (EAPC: -0.85). The global age-standardized DALYs also show a downward trend, except in high SDI and low-middle SDI regions. The highest incidence was observed among individuals aged 70-74 in 2021. By 2036, new cases are projected to rise, though incidence, mortality, and DALYs are expected to decline.

Conclusion: Regional disparities in the global UC burden highlight the need for tailored strategies, especially in low-income countries, to reduce its impact.

Objective: This study aimed to explore differences in disease extent based on the Proactive Molecular Risk Classifier for Endometrial Cancer (ProMisE) classification and to establish personalized staging surgery strategies in patients with preoperatively presumed uterus-confined endometrial cancer.

Methods: In this retrospective, single-center study, we reviewed the medical records of patients with endometrial cancer. These patients were classified according to the ProMisE classification based on tissue samples obtained from dilation and curettage or staging surgeries, and the disease extent was analyzed based on pathologic reports.

Results: A total of 345 patients were clinically estimated to be in stage 1/2 before staging surgery, with immunohistochemistry (IHC) results available. This cohort included 332 patients (96.2%) with clinical stage 1 and 13 patients (3.8%) with stage 2 based on the 2009 FIGO staging system. Among these, 81 patients (23.5%) were assigned to an mismatch repair deficient group (MMRd), 33 (9.6%) to an abnormal p53 group, and 123 (71.1%) to a no specific molecular profile (NSMP) group. Overall, 13 patients had nodal metastasis, with a higher rate observed in the abnormal p53 group (1.2%, 12.1%, and 2.2% for the MMRd, abnormal p53, and NSMP groups, respectively, p=0.013). One patient (0.3%) had parametrial metastasis and four (1.1%) had peritoneal metastasis.

Conclusion: Patients with abnormal p53 IHC results exhibited a higher likelihood of lymph node metastasis, even when initially presumed to be at an early stage. For the abnormal p53 group, proactive lymphadenectomy surgery appears beneficial for accurate staging and establishing a subsequent treatment plan.

This study reports the first case of transdiaphragmatic lateropericardial cardiophrenic lymph node excision using the GelPOINT™ mini access platform in a patient with advanced-stage ovarian cancer. A 69-year-old woman with high-grade serous epithelial ovarian cancer. Cardiophrenic lymph node dissection is vital in advanced ovarian cancer surgery, as enlarged nodes are linked to poor prognosis. No clear guidelines exist for operating on patients with enlarged cardiophrenic lymph nodes [1,2]. These nodes are categorized by location relative to the heart: anterior, median (lateropericardial), and posterior [3]. Cardiophrenic lymph node resection can be performed using transdiaphragmatic, transxiphoid, or transthoracic approaches with video-assisted thoracoscopic surgery [4]. In cases with suspicious nodes on imaging, removing them is essential for optimal cytoreduction and accurate staging. In this case, preoperative computed tomography revealed suspicious cardiophrenic lymph nodes measuring 16×13 mm and 10×8 mm, located near the xiphoid process and lateral pericardium. A 30 mm diaphragm incision was made 60 mm from the xiphoid process. An Alexis O-wound retractor was used, and the GelPOINT™ mini platform was introduced with three ports, including one for the camera. A 30-degree optic scope was used to excise the node with LigaSure. When we needed smoke management, we used an aspirator. With this method, we were able to access distally located cardiophrenic lymph nodes with a small incision. Transdiaphragmatic excision of the cardiophrenic lymph node using the mini access platform can be performed effectively with a smaller incision, demonstrating the feasibility and safety of this minimally invasive technique in managing such cases.

Due to the decreasing age of onset and the postponement of childbearing, there is a growing number of patients with endometrial carcinoma (EC) and endometrial atypical hyperplasia (EAH) seeking fertility-sparing treatments. Progestogen-based therapy serves as the principal conservative approach for EC. However, the variability in treatment outcomes hampers the potential for delivering more tailored therapies in clinical practice. To better guide the treatment of patients with fertility preservation needs, we conducted a comprehensive review of existing literature to explore factors related to molecular classification, biomarkers and artificial intelligence (AI) technology that may predict fertility-sparing treatment outcomes, we also looked ahead to future research directions in this field. The pathology before and after treatment is the primary basis for assessing the effectiveness of fertility-sparing treatment for EC and EAH. However, it is challenging to predict the therapeutic outcomes based on the pathological morphology of the initial diagnosis. Traditional immunohistochemical markers, such as estrogen and progesterone receptors, are also very limited in predicting therapeutic response. In recent years, the prognosis of fertility-sparing treatment has also been considered to be correlated with the molecular classification and gene mutation markers of EC. However, there are currently few direct clinical studies available, and our focus will be on reviewing these studies and assessing their applicability. In addition, there are some studies utilizing AI to predict the molecular classification, genes and therapeutic response of EC. The integration of these features will aid in the development of advanced predictive strategies for fertility-sparing treatment of EC and EAH.

Objective: Systemic chemotherapy in recurrent cervical cancer is a palliative treatment approach with limited oncologic outcome. As emerging evidence supports favorable prognosis following radical local treatment strategies for oligometastatic recurrence in gynecologic malignancies, there is an unmet clinical need to define prognostic implications of surgical metastasectomy in recurrent cervical cancer.

Methods: Data of 139 consecutive cervical cancer patients, who underwent primary external-beam radiotherapy with concomitant chemotherapy, followed by magnetic resonance image-guided adaptive brachytherapy between 2015 and 2019, was analyzed. Oncologic outcomes of recurrence patterns, defined according to the European Society for Radiotherapy and Oncology (ESTRO) and the American Society for Radiation Oncology (ASTRO) consensus, was assessed according to the type of recurrence therapy.

Results: Of 54 patients (38.8%) with metachronous disease recurrence, 21 (38.8%) classified as metastatic and 22 (40.7%) as oligometastatic. Oligometastatic recurrence was associated with improved progression-free survival after recurrence (PFS2; hazard ratio [HR]=2.95; 95% confidence interval [CI]=1.23-7.08; p=0.015) and disease-specific survival after recurrence (HR=3.28; 95% CI=1.40-7.70; p=0.006) irrespective of the type of recurrence therapy. An exploratory subgroup analysis of oligometastatic patients undergoing surgical resection ± adjuvant therapy (n=12) suggested reduced risk of second disease recurrence (odds ratio=0.15; 95% CI=0.02-0.92; p=0.020) and improved PFS2 (HR=0.24; 95% CI=0.06-0.99; p=0.048) as compared to palliative systemic treatment (n=7).

Conclusion: A relevant number of recurrences qualifies as oligometastatic according to the ESTRO-ASTRO consensus, which associate with improved prognosis irrespective of the type of recurrence therapy. Patients experiencing oligometastatic recurrence should be carefully evaluated for potentially curative treatment approaches.
