Background: Bulky or multiple lymph node (LN) metastases are associated with poor prognosis in cervical cancer, and the size or number of LN metastases is not yet reflected in the staging system and therapeutic strategy. Although the therapeutic effects of surgical resection of bulky LNs before standard treatment have been reported in several retrospective studies, wellplanned randomized clinical studies are lacking. Therefore, the aim of the Korean Gynecologic Oncology Group (KGOG) 1047/DEBULK trial is to investigate whether the debulking surgery of bulky or multiple LNs prior to concurrent chemoradiation therapy (CCRT) improves the survival rate of patients with cervical cancer IIICr diagnosed by imaging tests. Methods The KGOG 1047/DEBULK trial is a phase III, multicenter, randomized clinical trial involving patients with bulky or multiple LN metastases in cervical cancer IIICr. This study will include patients with a short-axis diameter of a pelvic or para-aortic LN ≥2 cm or ≥3 LNs with a short-axis diameter ≥1 cm and for whom CCRT is planned. The treatment arms will be randomly allocated in a 1:1 ratio to either receive CCRT (control arm) or undergo surgical debulking of bulky or multiple LNs before CCRT (experimental arm). CCRT consists of extended-field external beam radiotherapy/pelvic radiotherapy, brachytherapy and LN boost, and weekly chemotherapy with cisplatin (40 mg/m 2 ), 4–6 times administered intravenously.The primary endpoint will be 3-year progression-free survival rate. The secondary endpoints will be 3-year overall survival rate, treatment-related complications, and accuracy of radiological diagnosis of bulky or multiple LNs.

Background and Objectives: Prior studies have shown that stroke patients treated with percutaneous left atrial appendage occlusion (LAAO) for non-valvular atrial fibrillation (NVAF) experience better outcomes than similar patients treated with warfarin. We investigated the impact of percutaneous left atrial appendage closure on post-stroke neurological outcomes in NVAF patients, compared with non-vitamin K antagonist oral anticoagulant (NOAC) therapy. Methods: Medical records for 1,427 patients in multiple registries and for 1,792 consecutive patients at 6 Korean hospitals were reviewed with respect to LAAO or NOAC treatment.Stroke severity in patients who experienced ischemic stroke or transient ischemic attack after either treatment was assessed with modified Rankin Scale (mRS) scoring at hospital discharge and at 3 and 12 months post-stroke. Results: mRS scores were significantly lower in LAAO patients at 3 (p<0.01) and 12 months (p<0.01) post-stroke, despite no significant differences in scores before the ischemic cerebrovascular event (p=0.22). The occurrences of disabling ischemic stroke in the LAAO and NOAC groups were 36.7% and 44.2% at discharge (p=0.47), 23.3% and 44.2% at 3 months post-stroke (p=0.04), and 13.3% and 43.0% at 12 months post-stroke (p=0.01), respectively.Recovery rates for disabling ischemic stroke at discharge to 12 months post-stroke were significantly higher for LAAO patients (50.0%) than for NOAC patients (5.6%) (p<0.01). Conclusions Percutaneous LAAO was associated with more favorable neurological outcomes after ischemic cerebrovascular event than NOAC treatment.

Purpose: There is lack of data on direct comparison of survival outcomes between open surgery and robot-assisted staging surgery (RSS) using three robotic arms for endometrial cancer. The purpose of this study was to compare the overall survival (OS) and disease-free survival (DFS) between open surgery and RSS using three robotic arms for endometrial cancer. Materials and Methods: Consecutive women with endometrial cancer who underwent surgery between May 2006 and May 2018 were identified. Robotic procedures were performed using the da Vinci robotic system, and the robotic approach consisted of three robotic arms including a camera arm. Propensity score matching, as well as univariate and multivariate Cox regression of OS and DFS were performed according to clinicopathologic data and surgical method. Results: The study cohort included 423 unselected patients with endometrial cancer, of whom 218 underwent open surgery and 205 underwent RSS using three robotic arms. Propensity score-matched cohorts of 146 women in each surgical group showed no significant differences in survival: 5-year OS of 91% vs. 92% and DFS of 86% vs. 89% in the open and robotic cohorts, respectively (hazard ratio, 1.02; 95% confidence interval, 0.82–1.67). In the univariate analysis with OS as the endpoint, surgical method, age, stage, type II histology, grade, and lymph node metastasis were independently associated with survival. Surgical stage, grade, and type II histology were found to be significant independent predictors for OS in the multivariate analysis. Conclusion RSS using three robotic arms and laparotomy for endometrial carcinoma had comparable survival outcomes.

Emerging evidence has suggested that cytoreductive prostatectomy (CRP) allows superior oncologic control when compared to current standard of care androgen deprivation therapy alone. However, the safety and benefit of cytoreduction in metastatic prostate cancer (mPCa) has not been proven. Therefore, we evaluated the incidence of complications following CRP in men newly diagnosed with mPCa. A total of 68 patients who underwent CRP from 2006 to 2014 at four tertiary surgical centers were compared to 598 men who underwent radical prostatectomy for clinically localized prostate cancer (PCa). Urinary incontinence was defined as the use of any pad. CRP had longer operative times (200 min vs 140 min, P < 0.0001) and higher estimated blood loss (250 ml vs 125 ml, P < 0.0001) compared to the control group. However, both overall (8.82% vs 5.85%) and major complication rates (4.41% vs 2.17%) were comparable between the two groups. Importantly, urinary incontinence rate at 1-year after surgery was significantly higher in the CRP group (57.4% vs 90.8%, P < 0.0001). Univariate logistic analysis showed that the estimated blood loss was the only independent predictor of perioperative complications both in the unadjusted model (OR: 1.18; 95% CI: 1.02-1.37; P = 0.025) and surgery type-adjusted model (OR: 1.17; 95% CI: 1.01-1.36; P = 0.034). In conclusion, CRP is more challenging than radical prostatectomy and associated with a notably higher incidence of urinary incontinence. Nevertheless, CRP is a technically feasible and safe surgery for selecting PCa patients who present with node-positive or bony metastasis when performed by experienced surgeons. A prospective, multi-institutional clinical trial is currently underway to verify this concept.

OBJECTIVE: To compare clinicopathologic characteristics and surgical outcomes of laparoscopic surgery in women with endometrial cancer according to body mass index (BMI). METHODS: From June 2009 to October 2010, prospective observational study without randomization of 159 patients treated by laparoscopic surgery from 10 hospitals nationwide. RESULTS: Patients were divided according to the WHO guidelines for Asia-Pacific populations and the distributions of BMI were as follows: 3 patients (1.9%) in underweight (BMI < 18.5 kg/m2), 50 patients (31.4%) in normal weight (BMI, 18.5-22.9 kg/m2), 45 patients (28.3%) in overweight (BMI, 23.0-24.9 kg/m2), 49 patients (30.8%) in obese (BMI, 25.0-29.9 kg/m2), and 12 patients (7.5%) in morbid obese (BMI > or = 30.0 kg/m2). Age, history of previous surgery, surgery extend, and history of previous surgery were not different between non-obese patients (BMI < 25.0 kg/m2) and obese patients (BMI > or = 25.0 kg/m2). Co-morbidities were more common in obese patients but marginally significant (23.5% vs. 37.7%, p=0.072). Four patients (2.5%) were converted to abdominal surgery because of severe adhesion. Regarding to surgical outcomes, operation time was significantly longer in obese patients (199 min vs. 235 min, p=0.013) but blood loss, lymph node yield, hospital stay, Foley removal, transfusion rate and peri-operative complication were not statistically significant. Regarding to pathologic results, there were no difference in terms of lymphovasucular space invasion, tumor grade, histologic type, lymph node metastasis and FIGO stage. CONCLUSION: Clinicopathologic characteristics and surgical outcomes does not seem to be significantly influenced by BMI except operation time. So the laparoscopic approach can be the alternative method for obese patients.

OBJECTIVE: The purpose of this study was to evaluate the prognostic significance of tumor volume assessed by pretreatment MRI in stage IIB cervical cancer patients with concurrent chemoradiation therapy. METHODS: A retrospective chart review was performed on seventy five patients with cervical cancer who were treated with concurrent weekly cisplatin (40 mg/m2) and radiotherapy between January 2000 and April 2007. Potential prognostic factors were age, chemotherapy numbers, histology, tumor diameter and volume, lymph node (LN) involvement and pretreatment squamous cell carcinoma antigen (SCC-Ag) levels. RESULTS: The median follow-up time was 55 months (range, 8 to 104 months). The median tumor size and volume (range) were 4.5 cm (2 to 10) and 33.1 mL (4.2 to 392.7), respectively. Pelvic LN enlargement rate was 58.7%. Para-aortic LN enlargement rate was 14.7%. Using multivariate analysis, a tumor volume (>33 mL, p=0.025), pelvic LN enlargement (p=0.044) revealed a significantly unfavorable outcome on overall survival. PFS was influenced by tumor histology (p<0.001), pelvic LN enlargement (p=0.015) and pretreatment SCC-Ag levels (p=0.018). We found that 22 (29.3%) patients had recurrences and 14 (18.7%) patients died of disease. The 5-year overall survival rate was 80.6% (standard error, 4.9%) and 5-year PFS rate was 71.3% (standard error, 5.3%). CONCLUSION: Tumor volume and pelvic LN involvement showed possibility to predict overall survival in patient with stage IIB cervical cancer. Optimal tumor volume and pelvic LN assessment by pretreatment MRI might be helpful to predict treatment outcome.
