OBJECTIVE
To identify a relatively high-risk population in postoperative intermediate-risk cervical cancer and evaluate the effect of platinum-based adjuvant chemotherapy (CT).
METHODS
We retrospectively reviewed the medical records of patients with stage IA2-IIA cervical cancer who had been treated with radical hysterectomy and pelvic lymphadenectomy and classified as the intermediate-risk group for recurrence by postoperative pathological examination from January 2007 to December 2018 at 3 medical centers in Japan. First, patients with intermediate-risk were stratified by histological type and the number of intermediate-risk factors (IRF; large tumor diameter, lymph vascular space invasion, and deep cervical stromal invasion) and then divided into 2 groups: high and low-risk population (estimated 5-year recurrence-free survival [RFS] rate with no further therapy [NFT] <90% and ≥90%, respectively). Second, the efficacy of CT for the high-risk population was evaluated by comparing RFS and overall survival (OS) between the patients receiving CT and those with NFT.
RESULTS
In total, 133 patients were included in the analysis. Among patients with squamous cell carcinoma (SCC) with all IRF or those with non-SCC with 2 to 3 IRF, the 5-year estimated RFS was <90% when treated with NFT. In this population, adjuvant CT was significantly superior to NFT regarding RFS (log-rank, p=0.014), although there was no statistical difference in OS.
CONCLUSION
Patients with SCC with all 3 IRFs and those with non-SCC with 2 to 3 IRFs were at high risk for recurrence. Adjuvant CT is a valid treatment option for these populations.

Renal cell carcinoma (RCC) is an extremely rare cancer in pediatric, accounting for 0.1% to 0.3% of all pediatric malignancies. Due to its low incidence in this age group, literature on pediatric RCC is limited. We present a case of localized RCC in pediatric patient treated with nephroureterectomy and lymphadenectomy. A 14-year-old girl with a 2-year history of red urine, blood clots, and left flank pain underwent physical examination, revealing left flank tenderness. Laboratory results showed anemia, leukocytosis, elevated LDH, and erythrocytes in urine. Imaging revealed a hyperechoic area in the left kidney's lower pole (4.0 × 2.8 cm). Contrast abdominal CT scan indicated a solid mass (5.4 × 3.8 × 3.2 cm) in left renal pelvis extending to the minor calyx and severe hydronephrosis. The patient was diagnosed with suspected cT3N0M0 left upper tract urothelial carcinoma and underwent cystoscopy, bladder cuff excision, and left radical nephroureterectomy with paraaortic lymph node dissection. Pathological analysis revealed clear cell type renal cell carcinoma, WHO ISUP grade IV, extending to the perirenal fat, with tumor-free ureteral resection margins, and no paraaortic lymph node metastasis. Follow-up on postoperative period showed a satisfactory outcome. In cases of pediatric localized RCC, surgical therapy, including radical nephrectomy or nephron-sparing surgery (NSS), can be a preferred treatment for small tumor volumes. This approach preserves kidney function and is generally considered safe for achieving tumor-free margins.

Comparative Study
One of the most common cancers of the urinary tract is bladder tumors. Bladder cancers are divided into two groups: non-muscle-invasive bladder cancer (NMIBC) and muscle-invasive bladder cancer. (1) Trans-Peritoneal Radical Cystectomy (RC) with pelvic lymphadenectomy is the standard technique in muscle invasive and high risk non-muscle invasive bladder cancer (2). and Urologist around the world are more familiar with trans-peritoneal technique. In some articles extra-peritoneal Radical Cystectomy (RC) implied as an decreased postoperative complications techniques. In this letter we want to compare these two techniques and find out the pros and cons of these techniques.

Meta-Analysis
OBJECTIVE
Bladder cancer (BC) is the most common malignant tumour of the urinary system, and radical cystectomy combined with pelvic lymph node dissection (LND) is the standard treatment for BC. We conducted this meta-analysis to explore the efficacy and safety of extended lymph node dissection in radical cystectomy for BC.
METHODS
PubMed, Embase, ProQuest PsycINFO, CINAHL, Web of Science and The Cochrane Library databases were searched for studies on extended lymph node dissection during radical BC surgery. The search time limit was from the establishment of the database to December 2023. Screening and quality assessment of literature were conducted. This meta-analysis was conducted to evaluate the influence of different lymph node dissection methods on recurrence-free survival (RFS), overall survival (OS), operation time, 90-day readmission rate and postoperative complication rate.
RESULTS
A total of 15 studies were included, including 4854 patients. All studies were of high quality. This meta-analysis showed no statistically significant difference in the operation time, postoperative complications and 90-day hospitalisation rate between the two groups of patients. The harvested volume of lymph nodes, RFS and OS rate were not statistically different.
CONCLUSIONS
Among patients with BC undergoing radical cystectomy, extended lymph node dissection did not have a significant effect on operative time, 90-day readmission rates or postoperative complication rates. Thus, extended lymph node dissection is a safe treatment that does not increase the patient's surgical risk.

Faster both in operative time and functional recovery by the extraperitoneal daVinci SP-based robot-assisted radical prostatectomy: a propensity score matching analysis compared to transperitoneal multiport counterpart.
We aim to investigate the peri-operative outcomes after extraperitoneal single-port based robot-assisted radical prostatectomy (eSP-RARP) utilizing the da Vinci SP system compared to conventional transperitoneal multi-port counterparts (tMP-RARP), in an era when pelvic lymph node dissection (PNLD) was omitted for the node-negative case. With exclusion criteria of volume + 50 g, suspicious rectal invasion, and node-positive disease given relatively weak grasping power and limited range of motion from the current SP system, 50 consecutive patients (Since December 2021) with localized prostate cancer underwent eSP-RARP by a single urologist maintaining identical surgical technique for 100 consecutive tMP-RARP cases (Since December 2020). Given initial selection criteria, each group was matched to a 1:1 ratio based on the risk-stratification parameters and the prostate volume. The operative time, which was maintained in each group during the study period, was significantly faster in eSP-RARP groups than in tMP-RARP (149.2 vs. 163.2 min, p = 0.025), while the weight of the removed specimen (27.1 vs. 29.0 g, p = 0.420) and margin positivity (14.7% vs. 11.7% in pT2, p = 0.812) were similar. The gas-out (1.5 vs. 1.88 days, p = 0.003) and solid diet dates (2.26 vs. 3.22 days, p < 0.001) were faster in the eSP-RARP group. The single-pad continence dates (30.5 vs. 51.9 days, p = 0.145) and zero-pad continence dates (105.5 vs. 146.2 days, p = 0.210) were identical. 90-day single-pad continence rate was 92% vs. 82% (p = 0.142, 52% vs. 56% in zero-pad continence). Based on these, daVinci SP-based RARP restored bowel function faster with shorter operative time through an extraperitoneal approach than the conventional transperitoneal multi-port counterpart while maintaining similar incontinence outcomes in cases without a routine PNLD.

OBJECTIVE
To evaluate the effectiveness of methylene blue dye in detecting sentinel lymph nodes (SLNs) in women with early-stage operable (defined as FIGO I-IIA) cervical cancer. It also aims to evaluate procedural challenges and accuracy.
METHOD
This prospective study, which focused on 20 women with early-stage cervical cancer, was carried out between June 2016 and December 2017. These patients had SLN mapping with methylene blue dye injections and thorough examinations, including imaging. All patients underwent radical hysterectomy and complete bilateral pelvic lymphadenectomy. No additional investigation was done on the lymph node in cases where a metastasis was found in the first H&E-stained segment of the sentinel node.
RESULT
20 patients were included in the analysis. The median age of the subjects was 53, and 95 % of them had squamous cell carcinoma. 90 % of the time, the identification of SLNs was effective, and 55 SLNs were found, of which 52.7 % were on the right side of the pelvis and 47.3 % on the left. The obturator group had the most nodes, followed by the external and internal iliac groups in descending order of occurrence. Metastasis was detected in 3 patients, resulting in a sensitivity of 100 % and a specificity of 93.75 % for SLN biopsy. Notably, no false-negative SLNs were found. Complications related to methylene blue usage included urine discoloration in 30 % of patients.
CONCLUSION
This trial highlights the promising efficacy and safety of methylene blue dye alone for SLN identification in early-stage operable cervical cancer, with a notably higher success rate. Despite limitations like a small sample size, healthcare professionals and researchers can build upon the insights from this study to enhance cervical cancer management.

Clinical Trial
BACKGROUND
While total hysterectomy and bilateral salpingo-oophorectomy without lymph node staging are standard for low- and intermediate-risk endometrial cancer, certain histopathologic factors revealed after surgery can necessitate additional interventions. Our study assessed the influence of sentinel lymph node biopsy on postoperative decision-making.
MATERIALS AND METHODS
In the SENTRY trial (July 2021 - February 2023), we enrolled patients with International Federation of Gynaecology and Obstetrics (FIGO) stage IA-IB low-grade endometrioid endometrial cancer. Laparoscopic sentinel lymph node mapping using indocyanine green was performed alongside total hysterectomy with bilateral salpingo-oophorectomy. Subsequent management changes based on sentinel lymph node biopsy results were evaluated. The trial was registered at ClinicalTrials.gov (NCT04972682).
RESULTS
Of the 100 enrolled participants, a bilateral detection rate of 91% was observed with a median detection time of 10 min (interquartile range 8-13 min). Sentinel lymph node metastases were found in 8% (N = 8) of participants. Postoperative FIGO staging increased in 15% (N = 15) and decreased in 5% (N = 5) of patients. Sentinel lymph node biopsy results altered the adjuvant treatment plan for 20% (N = 20): external beam radiotherapy was omitted in 12% (N = 12) while 6% (N = 6) had external beam radiotherapy +/- systemic chemotherapy added due to sentinel lymph node metastases. In 2% (N = 2), the external beam radiotherapy field was expanded with the paraaortic region. No intraoperative complications were reported and no 30-day major morbidity and mortality occurred. Throughout a median follow-up of 14 (95% CI 12-15 months, neither patient-reported lymphedema nor pelvic recurrence surfaced in the cohort.
CONCLUSIONS
Sentinel lymph node biopsy using indocyanine green is a safe procedure and allows tailoring adjuvant therapy in presumed low- and intermediate-risk endometrial cancer. It assists in avoiding external beam radiotherapy overtreatment and introducing additional modalities when necessary.

OBJECTIVES
The surgical training of gynecologic oncology (GO) fellows is critical to providing excellent care to women with gynecologic cancers. We sought to evaluate changes in techniques and surgical volumes over an 18-year period among established GO fellowships across the US.
METHODS
We emailed surveys to 30 GO programs that had trained fellows for at least 18 years. Surveys requested the number of surgical cases performed by a fellow for seventeen surgical procedures over each of five-time intervals. A One-Way Analysis of Variance was conducted for each procedure, averaged across institutions, to examine whether each procedure significantly changed over the 18-year span.
RESULTS
14 GO programs responded and were included in the analysis using SPSS. We observed a significant increase in the use of minimally invasive (MIS) procedures (robotic hysterectomy (p < .001), MIS pelvic (p = .001) and MIS paraaortic lymphadenectomy (p = .008). There was a concurrent significant decrease in corresponding "open" procedures. There was a significant decrease in all paraaortic lymphadenectomies. Complex procedures (such as bowel resection) remained stable. However, there was a wide variation in the number of cases reported with extremely small numbers for some critical procedures.
CONCLUSIONS
The experience of GO fellows has shifted toward increased use of MIS. While these trends in care are appropriate, they do not diminish the need in many patients for complex open procedures. These findings should help spur the development of innovative training to maintain the ability to provide these core, specialty-defining procedures safely.

OBJECTIVES
A total mesenteric excision (TME) with lateral pelvic lymph node dissection (LLND) is the standard treatment for advanced low rectal cancer in Japan. Recently, neoadjuvant (chemo)radiotherapy (n(C)RT) has been used with LLND to improve outcomes at multiple Japanese institutes. This study evaluates the benefits of adding nCRT to TME with LLND.
METHODS
Seventy-two consecutive patients who underwent TME and LLND with or without nCRT between 2006-2019 to treat advanced low rectal cancer were retrospectively reviewed. The clinicopathological data were compared and the risk factors for local recurrence were evaluated.
RESULTS
Fifty-seven patients (79.1%) underwent TME and LLND with nCRT, and 15 patients (20.9%) without nCRT. There was no significant difference in the clinicopathological characteristics except the clinical T stage. The occurrence of postoperative complications was statistically insignificant. The 5-year local recurrence rate of patients with nCRT was significantly lower than those without (4.0% versus 26.6%, in all patients, =0.002). Multivariate analysis revealed that the absence of nCRT was an independent risk factor for local recurrences in patients who underwent TME with LLND (hazard ratio: 6.04, =0.04).
CONCLUSIONS
The administration of nCRT prevented local recurrences more effectively in patients with advanced low rectal cancer who underwent TME with LLND.

In this editorial, we proceed to comment on the article by Chua , addressing the management of metastatic lateral pelvic lymph nodes (mLLN) in stage II/III rectal cancer patients below the peritoneal reflection. The treatment of this nodal area sparks significant controversy due to the strategic differences followed by Eastern and Western physicians, albeit with a higher degree of convergence in recent years. The dissection of lateral pelvic lymph nodes without neoadjuvant therapy is a standard practice in Eastern countries. In contrast, in the West, preference leans towards opting for neoadjuvant therapy with chemoradiotherapy or radiotherapy, that would cover the treatment of this area without the need to add the dissection of these nodes to the total mesorectal excision. In the presence of high-risk nodal characteristics for mLLN related to radiological imaging and lack of response to neoadjuvant therapy, the risk of lateral local recurrence increases, suggesting the appropriate selection of strategies to reduce the risk of recurrence in each patient profile. Despite the heterogeneous and retrospective nature of studies addressing this area, an international consensus is necessary to approach this clinical scenario uniformly.
