RESUMEN
OBJECTIVE: To evaluate whether intraoperative rupture affects oncological outcomes in patients with early-stage epithelial ovarian cancer (EOC). METHODS: 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. RESULTS: 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). CONCLUSIONS: 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.
RESUMEN
BACKGROUND: Although two recent phase III randomized controlled trials showed survival benefits of undergoing secondary cytoreductive surgery for an initial relapse of ovarian cancer, patients who received a poly-ADP ribose polymerase inhibitor (PARPi) as the first-line maintenance treatment, which is currently the standard treatment for advanced ovarian cancer, were not included in those trials. Therefore, determining an optimal treatment strategy, including secondary cytoreductive surgery, in patients whose cancer progresses even with PARPi treatment, is needed. PRIMARY OBJECTIVE: To determine whether secondary cytoreductive surgery is beneficial in patients who have progressed on PARPi maintenance treatment. STUDY HYPOTHESIS: Secondary cytoreductive surgery followed by chemotherapy is superior to chemotherapy alone for patients who have progressed on PARPi maintenance treatment. TRIAL DESIGN: The SOCCER-P study is a multicenter randomized phase II clinical trial. Patients who meet the eligibility criteria will be randomized to either undergo secondary cytoreductive surgery and subsequent platinum-based chemotherapy plus or minus bevacizumab, or to receive platinum-based chemotherapy plus or minus bevacizumab alone. Patients randomly allocated to the surgery group will undergo secondary cytoreductive surgery followed by six cycles of a physician's choice of platinum-based chemotherapy once they have recovered from surgery. MAJOR INCLUSION/EXCLUSION CRITERIA: The major inclusion criteria are as follows: first recurrence of disease with treatment-free interval from last platinum dose (TFIp) ≥6 months and progression during PARPi maintenance or treatment-free interval from last PARPi therapy (TFIPARPi) <3 months. The major exclusion criteria are as follows: >1 line of prior chemotherapy, TFIp <6 months, and radiological signs suggesting metastases not accessible to surgical removal (complete resection is deemed not possible). PRIMARY ENDPOINT: Progression-free survival. SAMPLE SIZE: 124 patients. ESTIMATED DATES FOR COMPLETING ACCRUAL AND PRESENTING RESULTS: Accrual completion approximately the end of 2026 and the results are expected after 2 years of follow-up in 2029. TRIAL REGISTRATION: NCT05704621.
RESUMEN
BACKGROUND: This report describes the oncologic outcomes for patients with advanced ovarian cancer who had bowel surgery performed by gynecologic oncologists (GOs) and compares the outcomes with those for bowel surgery performed by general surgeons (GSs) during maximal cytoreductive surgery. METHODS: Patients from six academic institutions who had FIGO stage III or IV ovarian cancer and underwent any bowel surgeries during maximal cytoreductive surgery were eligible for the study. The patients were divided into two groups according to whether bowel surgery was performed by a GO or a GS. In both groups, the GOs were mainly involved in extra bowel debulking procedures. Perioperative and survival outcomes were compared between the two groups. RESULTS: The 761 patients in this study included 113 patients who underwent bowel surgery by a GO and 648 who had bowel surgery by a GS. No discernible differences were observed in age, American Society of Anesthesiology (ASA) score, FIGO stage, histologic type, timing of cytoreductive surgery (primary or interval debulking surgery), or complications between the two groups. The GO group exhibited a shorter operation time than the GS group. Kaplan-Meier analysis showed no survival differences between the two groups. In the Cox analysis, non-serous cell types and gross residual diseases were associated with adverse effects on overall survival. However, performance of bowel surgery by a GO did not have an impact on survival. CONCLUSION: Performance of bowel surgery by a GO during maximal cytoreductive surgery is both feasible and safe. These results should be reflected in the training system for GOs regarding bowel surgery, and further research is needed to confirm that GOs can play a more leading role in performing extra-uterine procedures.

We aimed to determine whether pretreatment squamous cell carcinoma antigen (SCC-Ag) levels and the average logarithmic change in SCC-Ag levels ( Δ log SCC-Ag Δ time ) after concurrent chemoradiotherapy (CCRT) could predict treatment outcomes in patients with stage IIIC1 cervical squamous cell carcinoma (SCC). We analyzed 168 patients with stage IIIC1 cervical SCC who underwent primary CCRT and collected data on age, local extension, treatment details, hematological parameters, and tumor markers such as SCC-Ag and carcinoembryonic antigen 21-1 (Cyfra). Predictive performances of pretreatment SCC-Ag levels and Δ log SCC-Ag Δ time were assessed using receiver operating characteristic curves. Survival analysis was performed using the Cox regression model and Kaplan-Meier plots. The combination of pretreatment SCC-Ag levels and Δ log SCC-Ag Δ time showed higher area under the curve values than pretreatment SCC-Ag levels alone (area under the curve; 95% confidence interval [CI] 0.708 [0.581-0.836] vs. 0.666 [0.528-0.804], respectively). Pretreatment SCC-Ag (≥ 5 ng/ml and Cyfra levels (≥ 3.15 ng/ml) and Δ log SCC-Ag Δ time (≥ - 1.575) were significant predictors of disease-specific survival. The 5-year disease-specific survival rates significantly differed among the low-, intermediate-, and high-risk groups. Risk stratification using both pretreatment SCC-Ag levels and Δ log SCC-Ag Δ time may predict treatment outcomes of patients with stage IIIC1 SCC.

OBJECTIVE: To evaluate whether treatment with erythropoiesis-stimulating agents (ESAs) for chemotherapy-induced anemia affects progression-free survival (PFS) in patients receiving front-line chemotherapy following surgery for ovarian cancer (OC). METHODS: We retrospectively reviewed all consecutive patients who received front-line chemotherapy after surgery between 2013 and 2019 at six institutions. The patients were divided according to the use of ESAs during front-line chemotherapy. The primary endpoint was PFS. The secondary endpoint was the occurrence of thromboembolism. Propensity score matching (PSM) analysis was used to compare survival between matched cohorts. RESULTS: Overall, 2147 patients (433 receiving ESA and 1714 for no-ESA) were identified, with a median follow-up of 44.0 months. The ESA group showed a significantly higher proportion of stage III/IV disease (81.8% vs 61.1%; P < 0.001) and postoperative gross residual disease (32.3% vs 21.2%; P < 0.001) than the no-ESA group. In the multivariable Cox regression analysis, the use of ESAs did not affect PFS (adjusted hazard ratio, 1.03; 95% confidence interval [CI]: 0.89-1.20; P = 0.661). The incidence of thromboembolism was 10.2% in the ESA group and 4.6% in the no-ESA group (adjusted odds ratio, 6.58; 95% CI: 3.26-13.28; P < 0.001). When comparing the well-matched cohorts after PSM, PFS did not differ between the ESA (median PFS 23.5 months) and no-ESA groups (median PFS 22.2 months) (P = 0.540, log-rank test). CONCLUSIONS: The use of ESAs during front-line chemotherapy did not negatively affect PFS in patients with OC after surgery but increased the risk of thromboembolism.
RESUMEN
OBJECTIVE: This study aimed to evaluate the therapeutic role of lymphadenectomy in patients surgically treated for clinically early-stage epithelial ovarian cancer (EOC). METHODS: This retrospective, multicenter study included patients with clinically early-stage EOC based on preoperative abdominal-pelvic computed tomography or magnetic resonance imaging findings between 2007 and 2021. Oncologic outcomes and perioperative complications were compared between the lymphadenectomy and non-lymphadenectomy groups. Independent prognostic factors were determined using Cox regression analysis. Disease-free survival (DFS) was the primary outcome. Overall survival (OS) and perioperative outcomes were the secondary outcomes. RESULTS: In total, 586 patients (lymphadenectomy group, n=453 [77.3%]; non-lymphadenectomy groups, n=133 [22.7%]) were eligible. After surgical staging, upstaging was identified based on the presence of lymph node metastasis in 14 (3.1%) of 453 patients. No significant difference was found in the 5-year DFS (88.9% vs. 83.4%, p=0.203) and 5-year OS (97.2% vs. 97.7%, p=0.895) between the two groups. Using multivariable analysis, lymphadenectomy was not significantly associated with DFS or OS. However, using subgroup analysis, the lymphadenectomy group with serous histology had higher 5-year DFS rates than did the non-lymphadenectomy group (86.5% vs. 74.4%, p=0.048; adjusted hazard ratio=0.281; 95% confidence interval=0.107-0.735; p=0.010). The lymphadenectomy group had longer operating time (p<0.001), higher estimated blood loss (p<0.001), and higher perioperative complication rate (p=0.004) than did the non-lymphadenectomy group. CONCLUSION: In patients with clinically early-stage EOC with serous histology, lymphadenectomy was associated with survival benefits. Considering its potential harm, lymphadenectomy should be performed according to histologic subtype and subsequent chemotherapy in patients with clinically early-stage EOC.

Complex surgery is an essential component in the management of advanced ovarian cancer. Furthermore, achieving complete gross resection in cytoreductive surgery appears to be associated with significant survival benefits in patients with advanced ovarian cancer. The goal of this review is to demonstrate the advancement of surgical techniques in gynecologic oncology surgery, including resection of disease within the intrathoracic and inguinal regions. This progress has expanded the option of surgery to more patients, especially those who would have previously been deemed inoperable. In this review we describe the most notable studies and reports of surgical resection of ovarian cancer involving cardiophrenic/supradiaphragmatic lymph nodes, mediastinum, lung pleura or parenchyma, and the inguinal region. We also describe the growing role that video-assisted thoracic surgery has played in advanced ovarian cancer diagnosis and management. The studies, series, and reports described demonstrate that comprehensive surgical procedures outside of the abdomen or pelvis can be both safe and feasible in properly selected patients. They also suggest that resection of disease outside of the abdomen or pelvis may benefit appropriately selected patients. Future studies are necessary to identify which patients may benefit most from upfront surgery versus neoadjuvant chemotherapy when ovarian cancer metastasis is present in the thoracic or inguinal regions.

OBJECTIVE: The aim of this study was to identify high- and low-risk subgroups of patients with lymph node (LN) metastasis in presumed early-stage endometrioid endometrial cancer (EC) patients. METHODS: Clinicopathologic data of presumed early-stage endometrioid EC patients (n=361) treated with lymphadenectomy between March 2000 and July 2022 were analyzed. None of the patient had definite evidence of LN metastasis in a preoperative magnetic resonance imaging (MRI). A received operating characteristic curve analysis was conducted to define the sensitivity and specificity for the combined preoperative risk factors for LN metastasis, which was determined by multivariate analysis. RESULTS: Nineteen patients (5.3%) had LN metastasis. Multivariate analysis identified cervical stromal invasion on MRI (odds ratio [OR]=4.386; 95% confidence interval [CI]=1.020-18.852; p=0.047), cornual location of tumor on MRI (OR=36.208; 95% CI=7.902-165.913; p<0.001), and lower uterine segment/isthmic location of tumor on MRI (OR=8.454; 95% CI=1.567-45.610; p=0.013) as independent prognostic factors associated with LN metastasis. Patients were categorized into low- and high-risk groups according to risk criteria. Significant differences in the rates of LN metastasis were observed between the two groups (0.4% vs. 22.2%, p<0.001). CONCLUSION: Approximately 95% of presumed early-stage endometrioid EC patients did not have LN metastasis. A model using tumor location was significantly correlated with the risk of LN metastasis. Even in presumed early-stage endometrioid EC patients, therefore, tumor location should be investigated to determine whether to perform LN assessment.

OBJECTIVE: This study aimed to determine the safety and efficacy of the RKP00156 vaginal tablet, a CDK9 inhibitor, in healthy women and patients with cervical intraepithelial neoplasia grade 2 (CIN2). METHODS: We conducted a phase 1/2a clinical trial of RKP00156. In step 1, RKP00156 at a dose of 10, 25, or 50 mg or a placebo tablet was administered transvaginally to 24 healthy women. In step 2, RKP00156 at a dose of 10, 25, or 50 mg or a placebo tablet was administered once daily for 4 weeks in 62 patients with CIN2. The primary endpoints of this trial were the safety of RKP00156 and the change in the human papillomavirus (HPV) viral load. RESULTS: A total of 86 patients were enrolled and randomized. RKP00156 administration did not cause serious drug-associated adverse events (AEs). Although no significant difference in the HPV viral load was found between the experimental and placebo groups, a reduction in the HPV viral load was observed in the 25 mg-dose group (-98.61%; 95% confidence interval=-99.83%, 4.52%; p=0.046) after treatment completion in patients with a high HPV viral load, despite a lack of statistical power. No differences in histologic regression and HPV clearance were observed. CONCLUSION: The safety of RKP00156 was proved with no serious AEs. Although the study did not show any significance in histologic regression and HPV clearance, our findings indicate that RKP00156 may have a possibility of short-term inhibitory effect on HPV replication in patients with higher viral loads.

Introduction: We evaluated the effect of high-dose polymeric nanoparticle micellar paclitaxel (PM-Pac) on survival in patients with stage III-IV high-grade serous ovarian cancer (HGSC) who underwent upfront surgery. Methods: We prospectively recruited the patients who received PM-Pac (280 mg/m2) and carboplatin at an area under the curve (AUC) of 5 (cohort 1) in two tertiary centers between October 2015 and June 2019. As historical controls, we retrospectively collected data on those who received paclitaxel (175 mg/m2) and carboplatin (AUC 5; cohort 2) or paclitaxel (175 mg/m2), carboplatin (AUC 5) and bevacizumab (15 mg/kg; cohort 3). Results: A total of 128 patients were divided into cohorts 1 (n=49, 38.3%), 2 (n=53, 41.4%), and 3 (n=26, 20.3%). Cohort 1 showed better progression-free survival (PFS) than cohort 2 in all patients and those treated with optimal debulking surgery (ODS; median, 35.5 vs. 28.1 and 35.5 vs. 28.9 months; p ≤ 0.01) despite no difference in PFS between cohorts 1 and 3 and between cohorts 2 and 3. In particular, stage III disease was a favorable factor for PFS, whereas cohort 2 was related to worse PFS (adjusted hazard ratios, 0.456 and 1.834; 95% confidence interval, 0.263 - 0.790 and 1.061 - 3.171), showing no difference in PFS between cohorts 1 and 3 in those treated with ODS. Conclusion: High-dose PM-Pac improved PFS compared to conventional chemotherapy, and the change of paclitaxel to PM-Pac had as much effect on PFS as the addition of bevacizumab in patients with stage III-IV HGSC who underwent ODS.
RESUMEN
Since the latest practice guidelines for ovarian cancer were developed by the Korean Society of Gynecologic Oncology (KSGO) in 2021, many studies have examined the efficacy and safety of various treatments for epithelial ovarian cancer (EOC). Therefore, the need to develop recommendations for EOC treatments has been raised. This study searched the literature using 4 key items and the Population, Intervention, Comparison, and Outcome: the efficacy and safety of poly-ADP ribose polymerase inhibitors in newly diagnosed advanced EOC; the efficacy and safety of intraperitoneal plus intravenous chemotherapy in optimally debulked advanced EOC; the efficacy and safety of secondary cytoreductive surgery in platinum-sensitive recurrent ovarian cancer; and the efficacy and safety of the addition of bevacizumab to platinum-based chemotherapy in first platinum-sensitive recurrent EOC patients who received prior bevacizumab. The evidence for these recommendations, according to each key question, was evaluated using a systematic review and meta-analysis. The committee of ovarian cancer of the KSGO developed updated guidelines for treatments of EOC.

PURPOSE OF REVIEW: To review evidence around the value and challenges of surgery for recurrent epithelial ovarian cancer (ROC). Both cytoreductive and palliative aspects will be addressed RECENT FINDINGS: Prospective and retrospective evidence demonstrates a significantly longer remission derived from the combination of surgical and systemic modalities as opposed to systemic treatment alone in carefully selected ROC-patients who have relapsed more than 6 months from the end of their 1st line platinum-based chemotherapy. Nevertheless, this benefit appears to be limited when total macroscopic tumor clearance is not achieved. Selection algorithms to identify optimal surgical candidates are of paramount importance to prevent surgical morbidity without the equivalent oncological benefit. In the palliative setting, the risks and benefits of salvage surgery need to be counterbalanced with the advances of conservative techniques for optimal care. Well-defined selection algorithms to identify those who will benefit from surgery in the relapsed setting appear to be the key to oncologic and surgical success.

OBJECTIVES: This meta-analysis was undertaken to systematically evaluate the effects of poly (ADP-ribose) polymerase inhibitor (PARPi) maintenance therapy on the survival of newly diagnosed advanced epithelial ovarian cancer (EOC) patients. METHODS/MATERIALS: A systematic literature search revealed 3,227 studies. A subsequent selection process identified seven suitable randomized studies that assessed the survival outcomes in newly diagnosed advanced EOC patients administered PARPi (n = 1921; the PARPi group) or placebo (n = 1150; the placebo group). The survival outcomes were compared with respect to the PARPi treatment regardless of bevacizumab maintenance therapy. All adverse events ≥ grade 3 were analyzed. Review Manager Version 5.4.1 software was used for the meta-analysis. RESULTS: The two-year progression-free survival (PFS) was significantly better in the PARPi group than the placebo (Hazard ratio [HR], 0.53; 95% confidence interval [CI], 0.41 to 0.68). Furthermore, patients in the PARPi group with the BRCA1/2 mutation (BRCAm), BRCA wild type, homologous-recombination deficiency (HRD), or HRD without BRCAm, but not with homologous-recombination proficiency had a significantly better two-year PFS than the patients in the placebo group. The five-year overall survival (OS) was comparable in the two groups, but patients in the PARPi group with BRCAm had a significantly better five-year OS than those in the placebo group (HR, 0.57; 95% CI, 0.44 to 0.74). In addition, the adverse event rate (≥ grade 3) was significantly higher in the PARPi group than in the placebo group (HR, 2.94; 95% CI, 1.13 to 7.63). CONCLUSIONS: In patients with newly diagnosed advanced EOC, PARPi maintenance therapy was significantly more effective in terms of survival than no PARPi treatment. However, the risk of serious adverse events was higher for patients who received PARPi maintenance therapy.

OBJECTIVE: To identify the risk factors for failure of first-line poly (ADP-ribose) polymerase inhibitor (PARPi) maintenance therapy in patients with advanced ovarian cancer. METHOD: Patients with stage III-IV epithelial ovarian cancer who received first-line PARPi maintenance therapy were retrospectively reviewed. Clinicopathologic factors were compared between two groups-recur/progression of disease (PD) and non-recur/PD. RESULTS: In total, 191 patients were included. Median follow-up was 9.9 months, and recurrence rate was 20.9%. BRCA mutations were found in 63.4% patients. Postoperative residual tumor (60.5% vs. 37.8%), non-high grade serous carcinoma (HGSC) (15.0% vs. 6.0%), neoadjuvant chemotherapy (NAC) (55.0% vs. 35.8%), and pre-PARPi serum CA-125 levels ≥23.5 U/mL (35.9% vs. 15.2%) were more frequently observed in the recur/PD group. Multivariate Cox-regression analysis revealed pre-PARPi serum CA-125 levels ≥23.5 U/mL (HR, 2.17; 95%CI, 1.03-4.57; p = 0.042), non-HGSC (3.28; 1.20-8.97; p = 0.021), NAC (2.11; 1.04-4.26; p = 0.037), and no BRCA mutation (2.23; 1.12-4.44; p = 0.023) as independent risk factors associated with poor progression-free survival (PFS). A subgroup analysis according to BRCA mutation status showed that pre-PARPi serum CA-125 levels ≥26.4 U/mL were the only independent risk factor for poor PFS in women with BRCA mutations (2.75; 1.03-7.39; p = 0.044). Non-HGSC (5.05; 1.80-14.18; p = 0.002) and NAC (3.36; 1.25-9.04; p = 0.016) were independent risk factors in women without BRCA mutations. CONCLUSION: High pre-PARPi serum CA-125 levels, non-HGSC histology, NAC, and no BRCA mutation might be risk factors for early failure of first-line PARPi maintenance therapy. In women with BRCA mutations, high pre-PARPi serum CA-125 levels, which represent a large tumor burden before PARPi, were the only independent risk factor for poor PFS.

Importance: Hyperthermic intraperitoneal chemotherapy (HIPEC) followed by interval cytoreductive surgery (ICS) has shown survival benefits for patients with advanced-stage ovarian cancer. However, there is still a lack of consensus regarding the integration of HIPEC into clinical practice. Objective: To evaluate the safety and effectiveness of ICS with HIPEC compared with ICS alone in clinical practice for patients with advanced-stage ovarian cancer. Design, Setting, and Participants: This prospective, multicenter, comparative effectiveness cohort study enrolled 205 patients with stage III or IV ovarian cancer who had received at least 3 cycles of neoadjuvant chemotherapy followed by ICS with HIPEC or ICS without HIPEC at 7 Korean Gynecologic Oncology Group institutions between September 1, 2017, and April 22, 2022. Nine patients were excluded because they did not meet the inclusion criteria. Exposures: Neoadjuvant chemotherapy followed by ICS with HIPEC or ICS without HIPEC. Main Outcomes and Measures: The primary end point was progression-free survival (PFS). Overall survival (OS) and the safety profile were the key secondary end points. Results: This study included 196 patients (median age, 58.0 years [range, 38-82 years]), of whom 109 underwent ICS with HIPEC and 87 underwent ICS without HIPEC. The median duration of follow-up was 28.2 months (range, 3.5-58.6 months). Disease recurrence occurred in 128 patients (65.3%), and 30 patients (15.3%) died. Interval cytoreductive surgery with HIPEC was associated with a significant improvement in median PFS compared with ICS without HIPEC (22.9 months [95% CI, 3.5-58.6 months] vs 14.2 months [95% CI, 4.0-56.2 months]; P = .005) and median OS (not reached [95% CI, 3.5 months to not reached] vs 53.0 [95% CI, 4.6-56.2 months]; P = .002). The frequency of grade 3 or 4 postoperative complications was similar in both groups (ICS with HIPEC, 3 of 109 [2.8%] vs ICS without HIPEC, 3 of 87 [3.4%]; P > .99). Among patients with recurrence, the frequency of peritoneal recurrence was lower in the ICS with HIPEC group than in the ICS without HIPEC group (21 of 64 [32.8%] vs 41 of 64 [64.1%]; P = .001). Conclusions and Relevance: This study suggests that ICS in conjunction with HIPEC was associated with longer PFS and OS than ICS without HIPEC for patients with advanced-stage ovarian cancer and was not associated with higher rates of postoperative complications. The lower rate of peritoneal recurrence after HIPEC may be associated with improved OS.

BACKGROUND: Hyperthermic intraperitoneal chemotherapy (HIPEC) has emerged as a treatment option at the time of cytoreductive surgery after neoadjuvant chemotherapy. The effect of active warming of HIPEC on postoperative pain needs to be investigated. This study aimed to investigate whether HIPEC reduces postoperative pain. METHODS: From the KOV-HIPEC-01 trial, a randomized controlled trial of HIPEC for advanced primary ovarian cancer, 184 patients with a residual tumor size <1 cm were randomly assigned to the HIPEC and control groups at a 1:1 ratio. The consumption of analgesics and pain scales were analyzed. Hyperthermic intraperitoneal chemotherapy was administered after cytoreductive surgery. The primary objective was to compare the consumption of opioids measured in morphine milligram equivalents and non-opioids measured as the maximum daily dose between the HIPEC and control groups. The secondary objective was to compare the minimum and maximum pain intensities on numeric rating scales between the two groups using a linear mixed model. RESULTS: Lesser consumption of non-opioids, with a lower mean maximum daily dose on postoperative days 1 and 2, was observed. The HIPEC group also experienced lower maximum pain intensities on postoperative day 1. No overall differences in the minimum or maximum pain intensities were observed on postoperative day 7. CONCLUSION: The addition of HIPEC to cytoreductive surgery did not lead to increased postoperative pain, as demonstrated by a reduction in the use of analgesics and lower scores on postoperative pain scales during the early postoperative period.
RESUMEN
OBJECTIVE: To identify clinicopathological factors associated with disease recurrence for patients with 2018 FIGO stage IA with lymphovascular invasion to IB1 cervical cancer treated with minimally invasive surgery (MIS). METHODS: A total of 722 patients with cervical cancer between January 2010 and February 2021 were identified. Clinicopathological factors related to disease recurrence were analyzed. Disease-free survival (DFS) and overall survival (OS) rates were estimated using the Kaplan-Meier method. To determine prognostic factors for DFS, a Cox proportional hazard regression model was used. RESULTS: Of 722 patients, 49 (6.8%) experienced disease recurrence (37 pelvis, 1 para-aortic lymph node, and 11 peritoneum). Five-year DFS and OS rates were 90.7% and 98.1%, respectively. In multivariate analysis, risk factors associated with disease recurrence were residual disease in the remaining cervix (OR, 3.122; 95% CI, 1.152-8.461; p = 0.025), intracorporeal colpotomy (OR, 3.252; 95% CI, 1.507-7.017; p = 0.003), and positive resection margin (OR, 3.078; 95% CI, 1.031-9.193; p = 0.044). The non-conization group had a higher percentage of stage IB1 (77.4% vs. 64.6%; p = 0.004) and larger tumor (10 mm vs. 7 mm; p < 0.001) than the conization group. Intracorporeal colpotomy and residual disease in the remaining cervix were independent variables associated with disease recurrence in patients undergoing MIS following conization. CONCLUSION: During MIS, patients with cervical cancer ≤2 cm in size can be vulnerable to peritoneal recurrences. Patients diagnosed with invasive cancer through conization often have low-risk pathological features, which may affect their survival outcomes.

BACKGROUND: To identify those most likely to benefit from secondary cytoreductive surgery (SCS), we evaluated the survival outcomes and factors predictive of prognosis in patients with recurrent ovarian cancer. METHODS: We retrospectively reviewed the medical records of patients with recurrent ovarian cancer treated at five high-volume Korean hospitals between 2010 and 2021. Recurrence characteristics, treatment methods, and potential predictors of survival were compared between the chemotherapy and surgery groups. RESULTS: Among all 670 patients, 88.1% had initial stage III/IV disease, and 215 (32.1%) underwent SCS. Among patients who underwent SCS, only those who achieved complete resection exhibited improved survival. Even in patients with residual disease < 1 cm after SCS, we observed no significant survival benefit (p = 0.942). In the multivariate Cox analysis, residual disease at primary surgery, progression-free interval, recurrence sites (≤3 regions or limited carcinomatosis), ascites, and SCS were significant predictors of survival. Meanwhile, the only factor predictive of complete resection after SCS was recurrence sites (p < 0.001). CONCLUSIONS: The benefits of SCS appear to be exclusive to cases of complete resection. We propose limited regional platinum-sensitive recurrence (≤3 regions or limited carcinomatosis) without ascites as the optimum selection criteria for SCS.

OBJECTIVES: To evaluate oncologic and pregnancy outcomes of fertility-sparing treatment (FST) using progestin in patients with stage I grade 2 endometrioid endometrial cancer (EC) without myometrial invasion (MI) or grade 1-2 with superficial MI. METHODS: Multicenter data of patients with stage I grade 2 EC without MI or grade 1-2 EC with superficial MI, who received FST between 2005 and 2021, were analyzed. Cox regression analysis identified independent factors for progressive disease (PD) during the FST. RESULTS: Altogether, 54 patients received FST [medroxyprogesterone acetate (500-1000 mg) in 44, megestrol acetate (40-800 mg) in 10] with concurrent levonorgestrel-releasing intrauterine devices use in 31. With median time to achieve a complete response (CR) of 10 (3-24) months, 39 patients (72.2%) achieved CR. Of the 15 patients who attempted to conceive after achieving CR, 7 (46.7%) became pregnant (2 abortions, 5 live births). During a median FST duration of 6 (3-12) months, nine patients (16.6%) were diagnosed with PD. Fifteen (38.5%) experienced recurrence with a median recurrence-free survival of 23 (3-101) months. In the multivariable analysis, tumor size before FST ≥2 cm (HR 5.456, 95% CI 1.34 to 22.14; p = 0.018) was significantly associated with a high PD rate during FST. CONCLUSION: The overall response rate to FST was promising, however, the PD rate was significant during the first 12 months of FST. Therefore, performing thorough endometrial biopsy and imaging studies is essential to strictly evaluate the extent of the disease every 3 months from FST initiation.

BACKGROUND: There have been no studies concerning the complications or benefits of cholecystectomy in ovarian cancer. In this study, we aimed to evaluate the outcomes of cholecystectomy performed during various time periods of the disease course and suggest a management strategy for cholecystectomy in ovarian cancer. METHODS: We retrospectively reviewed the medical records of patients with advanced ovarian cancer who underwent cholecystectomy during the cytoreductive surgery from 2009 to 2020. Cholecystectomy was primarily indicated when the gallbladder and surrounding structures were considered to have metastatic tumor invasion. If the final pathologic results showed free of malignant tumor, patients were placed into the no-infiltration group. Clinical outcomes including the recurrence rate and complications were analyzed. RESULTS: A total of 62 patients underwent cholecystectomy, 48 of whom (77.4%) underwent cholecystectomy during primary or interval debulking surgery, whereas 14 (22.6%) underwent cholecystectomy during the follow-up period (five with benign disease and 9 with disease recurrence). Among the patients, 32 (51.6%) patients were included in the no-infiltration group in the final pathology. There were no complications observed in the no-infiltration group (n = 32). Seven (78%) of the nine patients who received cholecystectomy for disease recurrence had metastatic disease in the porta-hepatis or lesser sac at the time of primary surgery. However, no recurrent lesions were observed around the porta-hepatis in patients who received cholecystectomy during primary treatment. CONCLUSION: Considering the safety of the procedure, as well as the risk of disease recurrence or cholecystitis, a cholecystectomy can be offered to patients with ovarian cancer who have metastatic lesions around the gallbladder and porta-hepatis at the time of primary surgery.
