BACKGROUND
The aim of our study was to compare the number of lymph nodes removed during indocyanine green (ICG)-guided laparoscopic/robotic pelvic lymphadenectomy with standard systematic lymphadenectomy in endometrial cancer (EC) and cervical cancer (CC).
METHODS
This is a multicenter retrospective comparative study (Clinical Trial ID: NCT04246580; updated on 31 January 2023). Women affected by EC and CC who underwent laparoscopic/robotic systematic pelvic lymphadenectomy, with (cases) or without (controls) the use of ICG tracer injection within the uterine cervix, were included in the study.
RESULTS
The two groups were homogeneous for age ( = 0.08), Body Mass Index, International Federation of Gynaecology and Obstetrics (FIGO) stages ( = 0.41 for EC; = 0.17 for CC), median estimated blood loss ( = 0.76), median operative time ( = 0.59), and perioperative complications ( = 0.66). Nevertheless, the number of lymph nodes retrieved during surgery was significantly higher ( = 0.005) in the ICG group ( = 18) compared with controls ( = 16).
CONCLUSIONS
The accurate and precise dissection achieved with the use of the ICG-guided procedure was associated with a higher number of lymph nodes removed in the case of systematic pelvic lymphadenectomy for EC and CC.

BMC Urology Mar 2022To investigate whether Pentafecta is suitable for bladder cancer patients receiving laparoscopic radical cystectomy (LRC).
BACKGROUND
To investigate whether Pentafecta is suitable for bladder cancer patients receiving laparoscopic radical cystectomy (LRC).
METHODS
From November 2013 to December 2020, muscle invasive Bladder Cancer (MIBC) and non-muscle invasive Bladder Cancer (NMIBC) patients who received LRC and urinary diversion were retrospectively analyzed. Pentafecta was defined as meeting five criteria: negative soft margin, ≥ 16 lymph nodes (LNs) removed, major complications free, urinary diversion related sequelae free and clinical recurrence free within 1 year. Analyze the achievement of five criteria and compare the overall survival (OS) of Pentafecta group with non-attainment group. Multivariable Cox's regression was performed to evaluate the impact of Pentafecta on OS. Multivariable logistic regression was performed to explore the effect of surgical experience on Pentafecta attainment.
RESULTS
A total of 340 patients were included, negative soft margin, ≥ 16 lymph nodes (LNs) removed, major complications free, urinary diversion related sequelae free and clinical recurrence free within 1 year were observed in 95.3%, 30.3%, 83.8%, 75.0% and 85.6% of patients, respectively. Pentafecta group had a significantly longer OS than the non-attainment group (P = 0.027). The group with 10-15 LNs removed and meeting the other four criteria had a similar OS to group with ≥ 16 LNs removed (Pentafecta group) (5-year OS: 67.3% vs 72.7%, P = 0.861). Pentafecta (HR = 0.33, P = 0.011), positive lymph nodes (HR = 2.08, P = 0.028) and MIBC (HR = 3.70, P < 0.001) were all significant predictors of OS in multivariable Cox's regression. Surgical experience (OR = 1.05, P < 0.001), conduit (OR = 2.09, P = 0.047) and neobladder (OR = 2.47, P = 0.048) were all independent predictors of Pentafecta attainment in multivariable logistic regression.
CONCLUSIONS
Pentafecta is suitable for bladder cancer patients receiving LRC and has the potential to be a valuable tool for evaluating the quality of LRC. Based on Pentafecta analysis, removing 10 LNs instead of 16 LNs as the one of the five criteria may be more appropriate for bladder cancer patients.

Gynecologic Oncology Jun 2022Comparing the anatomical distribution of metastatic and non-metastatic pelvic sentinel lymph nodes (SLN) in cervical and endometrial cancer.
OBJECTIVE
Comparing the anatomical distribution of metastatic and non-metastatic pelvic sentinel lymph nodes (SLN) in cervical and endometrial cancer.
METHODS
Detailed SLN mapping results were prospectively retrieved in cervical (n = 145) or high-risk endometrial cancer (n = 201) patients undergoing a robotic staging procedure. Cervically injected Indocyanine Green (ICG), allowing for reinjection in case of inadequate mapping, was used as tracer. An anatomically based definition of SLNs was adhered to evaluating the upper (UPP) and lower (LPP) paracervical lymphatic pathways. The positions of SLNs were intraoperatively depicted on an anatomical chart. A completory pelvic lymphadenectomy was performed. Mapping rates and anatomical distribution of SLNs and the location of pelvic nodal metastases were compared between groups.
RESULTS
The bilateral mapping rate was 97.9% and 95.0% for cervical and endometrial cancer respectively (p = .16). The proportion of typically positioned (interiliac and proximal obturator fossa) SLNs along the UPP was similar between groups (78.1% vs 82.1%, p = .09), and the rate of metastatic SLNs in the obturator fossa was 54.1% and 48.6% respectively (p = .45). All pelvic node positive women (cervical cancer n = 19, endometrial cancer n = 37) had at least one metastatic SLN. Anatomically typical positions could not be defined along the LPP.
CONCLUSION
The anatomical location of SLNs and SLN metastases are similar in cervical and endometrial cancer suggesting that sensitivity results for an SLN concept in endometrial cancer and cervical cancer can be accumulated.

Journal of Gynecologic Oncology Nov 2023This study aimed to validate the surgical and oncologic outcomes of robotic surgery with sentinel node navigation surgery (SNNS) in endometrial cancer.
OBJECTIVE
This study aimed to validate the surgical and oncologic outcomes of robotic surgery with sentinel node navigation surgery (SNNS) in endometrial cancer.
METHODS
This study included 130 patients with endometrial cancer, who underwent robotic surgery, including hysterectomy, bilateral salpingo-oophorectomy, and pelvic SNNS at the Department of Obstetrics and Gynecology of Kagoshima University Hospital. Pelvic sentinel lymph nodes (SLNs) were identified using the uterine cervix 99m Technetium-labeled phytate and indocyanine green injections. Surgery-related and survival outcomes were also evaluated.
RESULTS
The median operative and console times and volume of blood loss were 204 (range: 101-555) minutes, 152 (range: 70-453) minutes, and 20 (range: 2-620) mL, respectively. The bilateral and unilateral pelvic SLN detection rates were 90.0% (117/130) and 5.4% (7/130), respectively, and the identification rate (the rate at which at least one SLN could be identified on either side) was 95% (124/130). Lower extremity lymphedema occurred in only 1 patient (0.8%), and no pelvic lymphocele occurred. Recurrence occurred in 3 patients (2.3%), and the recurrence site was the abdominal cavity, with dissemination in 2 patients and vaginal stump in one. The 3-year recurrence-free survival and 3-year overall survival rates were 97.1% and 98.9%, respectively.
CONCLUSION
Robotic surgery with SNNS for endometrial cancer showed a high SLN identification rate, low occurrence rates of lower extremity lymphedema and pelvic lymphocele, and excellent oncologic outcomes.

BACKGROUND
Lower limb or trunk melanoma often presents with femoral and pelvic sentinel lymph nodes (SLNs). The benefits of harvesting pelvic lymph nodes remain controversial. In this retrospective study, the frequency and predictors of pelvic SLNs (PSLNs), and the impact of PSLNs on survival and staging was investigated.
METHODS
Altogether 285 patients with cutaneous melanoma located in the lower limb or trunk underwent sentinel lymph node biopsy of the inguinal/iliac lymph node basin at Helsinki University Hospital from 2009-2013. Patient characteristics, detailed pathology reports and follow-up data were retrieved from hospital files. Subgroups of patients categorized by presence of PSLNs were compared for outcome parameters including progression-free survival, melanoma-specific survival and groin recurrence.
RESULTS
Superficial femoral/inguinal SLNs were present in all patients and 199 (69.8 per cent) also had PSLNs removed. Median number of SLNs per patient was five and median number of PSLNs was two. Sixty-three patients (22.1 per cent) had metastases in their SLNs and seven (2.5 per cent) had metastases in PSLNs. A single patient had metastases solely in PSLNs, while superficial SLNs remained negative. Harvesting PSLNs or the number of PSLNs retrieved had no impact on progression-free survival or overall survival. The removal of PSLNs did not affect the risk of postoperative seroma or lymphoedema. The only predictor of positive PSLNs was radioactivity count equal to or more than that of the hottest superficial SLNs.
CONCLUSION
Pelvic SLNs have minimal clinical impact on the outcome of melanoma patients especially in cases with negative superficial femoral/inguinal SLNs. Removal of PSLNs should be considered when they are the most radioactive nodes or equal to the hottest superficial femoral/inguinal SLNs in lymphoscintigraphy or during surgery.Preliminary results were presented in part at the International Sentinel Node Society Biennial Meeting, Tokyo, Japan, 11-13 October 2018.

Review
Upon discovery of lymph node metastasis during radical hysterectomy with pelvic lymphadenectomy in early-stage cervical cancer, the gynaecologist may pursue one of two treatment strategies: abandonment of surgery followed by primary (chemo)radiotherapy (PRT) or completion of radical hysterectomy, followed by adjuvant (chemo)radiotherapy (RHRT). Current guidelines recommend PRT over RHRT, as combined treatment is presumably associated with increased morbidity. However, this review of literature suggests there are no significant differences in survival and recurrence and total proportions of adverse events between treatment strategies. Additionally, both strategies are associated with varying types of adverse events, and affect quality of life and sexual functioning differently, both in the short and long term. Although total proportions of adverse events were comparable between treatment strategies, lower extremity lymphoedema was reported more often after RHRT and symptom experience (e.g. distress from bladder or bowel problems) and sexual dysfunction more often after PRT. As reporting of adverse events, quality of life and sexual functioning were not standardised across the articles included, and covariate adjustment was not conducted in most of the analyses, comparability of studies is hampered. Accumulating retrospective evidence suggests no major differences on oncological outcome and morbidity after PRT and RHRT for intraoperatively discovered lymph node metastasis in cervical cancer. However, conclusions should be considered cautiously, as all studies were of retrospective design with small sample sizes. Still, treatment strategies seem to affect adverse events, quality of life and sexual functioning in different ways, allowing room for shared decision-making and personalised treatment.

Review
Bladder cancer, a common malignancy of the urinary system, is routinely treated with radiation, chemotherapy, and surgical excision. However, these strategies have inherent limitations and may also result in various side effects. Immunotherapy has garnered considerable attention in recent years as a novel therapeutic approach. It harnesses and activates the patient's immune system to recognize and eliminate cancer cells, which not only prolongs therapeutic efficacy but also minimizes the toxic side effects. Several immune checkpoint inhibitors and cancer vaccines have been developed for the treatment of bladder cancer. Whereas blocking immune checkpoints on the surface of tumor cells augments the effect of immune cells, immunization with tumor-specific antigens can elicit the production of anti-tumor immune effector cells. However, there are several challenges in applying immunotherapy against bladder cancer. For instance, the efficacy of immunotherapy varies considerably across individual patients, and only a small percentage of cancer patients are responsive. Therefore, it is crucial to identify biomarkers that can predict the efficacy of immunotherapy. Pelvic lymph nodes are routinely dissected from bladder cancer patients during surgical intervention in order to remove any metastatic tumor cells. However, some studies indicate that pelvic lymph node dissection may reduce the efficacy of immunotherapy by damaging the immune cells. Therefore, the decision to undertake pelvic lymph node removal should be incumbent on the clinical characteristics of individual patients. Thus, although immunotherapy has the advantages of lower toxic side effects and long-lasting efficacy, its application in bladder cancer still faces challenges, such as the lack of predictive biomarkers and the effects of pelvic lymph node dissection. Further research is needed to explore these issues in order to improve the efficacy of immunotherapy for bladder cancer.

One of the most intense controversies in endometrial cancer revolves around the need for lymphadenectomy at the time staging. The study carried out to analyze the role of staging with pelvic lymphadenectomy in intermediate-risk stage I endometrial cancer-stage IA grade III and stage IB grades I and II. Review analysis of all the patients with stage I carcinoma endometrium intermediate risk treated at our institution between January 2006 and December 2014. All demographic data, tumor factors, adjuvant treatment, follow-up, and recurrence were recorded. Sixty-five were in intermediate-risk group, of which 21 were in low intermediate- and 44 in high intermediate-risk group, with 4 patients with positive pelvic node in each group. In patients with low intermediate-risk stage IA, grade III tumors, the nodal involvement was substantial even when the myometrial invasion was less than 50%. All grade 1 tumors did not have pelvic nodal metastasis. Overall percentage of pelvic nodal metastasis in our review of intermediate-risk carcinoma endometrium was 12%, with 19% in stage IA, grade III tumors, and 9% with stage IB, grade I and II tumors. A systematic lymphadenectomy should be done in patients with endometrial cancer who are at intermediate to high risk of lymph node metastases. The grade III histology is more likely to predict for nodal metastasis more than depth of myometrial invasion. It is recommended to stratify patients into risk groups to formulate guidelines for therapeutic lymphadenectomy.

INTRODUCTION
This was a surgical pilot study to systematically introduce the technique of sentinel lymph node (SLN) mapping in women with early-stage stage cervical cancer (CC) and endometrial cancer (EC) in Denmark. The study aimed to facilitate structured surgical training to ensure surgeon proficiency in SLN mapping. The study precedes two national prospective studies on the oncological safety and correct patient selection for SLN mapping in CC and EC.
METHODS
The study was conducted at four gynaecological cancer centres at Odense and Aarhus University Hospital, Rigshospitalet and Herlev Hospital, between September 2016 and August 2019. All centres went through a protocolled introduction to the surgical technique, pelvic lymphatic drainage, pathological ultra-staging and data entry. A criterion of a total (uni- and bilateral) SLN detection of > 80%, based on 30 SLN mappings was set.
RESULTS
The four centres performed 140 (range: 30-46) procedures. The total SLN detection rate was 91.3% with bilateral SLN detection in 68.8% and unilateral SLN detection in 22.5% of cases. The cumulated total SLN detection rate at three centres was above the pre-set 80% criterion from the beginning of inclusion, whereas one centre reached the criterion after 20 procedures.
CONCLUSIONS
In this study, all centres demonstrated international-level SLN detection rates within 30 procedures. Hence, all centres met the study criterion regarding surgeon proficiency and were eligible for the national studies.

Since sentinel lymph node mapping in endometrial cancer is becoming more widely used, the need of standardizing surgical technique is growing [1, 2]. The objective of this surgical video is to describe the procedure of two-step pelvic and para-aortic sentinel lymph node mapping using indocyanine green and fluorescent camera in endometrial cancer, in three versions of surgical modality of laparoscopic, robotic, and open laparotomy. The patients in the surgical video are diagnosed with biopsy-proven endometrial cancer in its early stage determined by the preoperative imaging study. After collecting washing cytology, bilateral salpinges were clamped with Endo Clip™ to minimize tumor spillage. Gauze packing in posterior cul-de-sac was done to minimize the spillage of indocyanine green dye during paraaortic sentinel lymph node mapping. Indocyanine green dye was injected in bilateral uterine fundus, to detect isolated paraaortic sentinel lymph node pathway. After bilateral paraaortic sentinel lymph node was sampled, cervical injection of Indocyanine green dye was done in 3 o'clock and 9 o'clock directions, both superficially and deeply, 2 mL in each side. After dissecting off the obliterated umbilical ligament, para-vesical and para-rectal spaces were developed. The ureter, uterine artery, and internal and external iliac vessels were identified before bilateral pelvic sentinel lymph nodes were sampled. Asan Medical Center's Institutional Review Board exempted this project. Sentinel paraaortic and pelvic lymph nodes were successfully harvested by two-step method of sentinel lymph node mapping through laparoscopic, robotic, and open laparotomy methods. This surgical video provides specific steps of pelvic and para-aortic sentinel lymph node mapping.
