STUDY OBJECTIVE
We sought to estimate the impact of sentinel nodes in gynecologic oncology on fellowship training and discuss potential solutions.
DESIGN
Retrospective multi-institution cohort (Canadian Task Force classification II-2).
SETTING
Three tertiary cancer referral cancer centers.
PATIENTS
Patients with endometrial and vulvar cancer undergoing lymph node evaluation.
INTERVENTIONS
Patient history and fellow case volumes were evaluated retrospectively for type of lymph node assessment.
MEASUREMENTS AND MAIN RESULTS
Minimally invasive endometrial cancer and vulvar cancer fellow case volumes in 3 large institutions were reviewed and average annual volumes calculated for each clinical gynecologic oncology fellow. For vulvar cancer, probabilities of sentinel lymph node mapping and laterality of lesions were estimated from the literature. For endometrial cancer, estimates of lymphadenectomy rates were determined using probabilities calculated from our historic database and from review of the literature. Modeling the approaches to lymphadenectomy in endometrial cancer (full, selective, and sentinel), 100% versus 68% versus 24%, respectively, of patients would require complete pelvic lymphadenectomy and 100% versus 34% versus 12% would require para-aortic lymphadenectomy. In vulvar cancer, rates of inguinal femoral lymphadenectomy are expected to drop from 81% of unilateral groins to only 12% of groins.
CONCLUSIONS
Sentinel lymph node biopsy for endometrial and vulvar cancer will play an increasing role in practice, and coincident with this will be a dramatic decrease in pelvic, para-aortic, and inguinal femoral lymphadenectomies. The declining numbers will require new strategies to maintain competency in our specialty. New approaches to surgical training and continued medical education will be necessary to ensure adequate training for fellows and young faculty across gynecologic surgery.

BACKGROUND
Performing lymphadenectomy in all patients with early-stage endometrial cancer (EC) is debatable because the procedure may expose patients to unnecessary risks of postoperative complications. Aim of this study was to evaluate the prevalence and risk factors of pelvic lymph node metastasis (PLNM) in patients with apparently early-stage EC.
MATERIALS AND METHODS
Two hundred and two patients with apparently early-stage EC who underwent surgical staging at Thammasat University Hospital between the years 2013 and 2020 were included in this retrospective study. Clinicopathological data and preoperative laboratory results were obtained from computer-based medical records. All data were statistically analyzed to determine the prevalence of PLNM and risk factors for developing PLNM.
RESULTS
PLNM was detected in 22 (10.9%) patients. Univariate analysis demonstrated that having grade 3 tumor, myometrial invasion of 50% or greater, vaginal involvement, cervical involvement, adnexal involvement, lower uterine segment involvement, lymphovascular space invasion (LVSI), and positive peritoneal cytology were associated with higher risk for developing PLNM. In addition, lower preoperative hemoglobin level and higher preoperative white blood cell count were significantly associated with PLNM. Multivariate analysis demonstrated that myometrial invasion of 50% or greater and LVSI were independent risk factors for developing PLNM (odds ratio (OR) 9.31, 95% confidence interval (CI) 2.58-33.55, p = 0.001, and OR 3.73, 95%CI 1.39-10.02, p = 0.009, respectively).
CONCLUSIONS
Myometrial invasion of 50% or greater and LVSI were independent risk factors for developing PLNM in patients with apparently early-stage EC and thus lymphadenectomy in these patients should be provided.

Review
Ovarian cancer has the highest mortality rate among the female genital malignancies. Its incidence is steadily increasing worldwide, especially in highly industrialized countries. Scarce and non-specific clinical symptoms in the early stages, and lack of effective screening methods, are the reasons why in the majority of cases the disease is diagnosed in advanced stage. Early diagnosis and optimal therapeutic method have significant impact on the prognosis. Surgery remains the basic treatment method in all stages of ovarian cancer. The general principle is the removal of the entire tumor or maximal cytoreduction. Pelvic and para-aortic lymphadenectomy is an integral part of the operating protocol. Evaluation of the regional lymph nodes is an important element of the diagnosis in patients with ovarian cancer, as the disease stage and the decision about the method of adjuvant therapy both depend on it. The diagnostic value of lymphadenectomy is unquestionable and is the basis of proper classification, while its therapeutic value remains the subject of controversy. The aim of the paper is to review the results of the most important research concerning lymphadenectomy in ovarian cancer, based on the available literature.

A multicenter noninferior randomized controlled study of sentinel lymph node biopsy alone versus sentinel lymph node biopsy plus lymphadenectomy for patients with stage I endometrial cancer, INSEC trial concept.
BACKGROUND
Up to the present time, there has remained a lack of strong evidence as to whether sentinel lymph node biopsy can replace lymphadenectomy for early endometrial cancer. The traditional surgery for endometrial cancer includes pelvic lymphadenectomy and paraaortic lymph node resection, but complications often seriously affect patients' quality of life. Two randomized controlled trials with large samples have proved that lymphadenectomy does not improve the overall recurrence rate and survival rate of patients. On the contrary, it increases the incidence of complications and even mortality. The current trial is designed to clarify whether sentinel lymph node biopsy can replace lymphadenectomy for early endometrial cancer patients with negative lymph nodes.
METHODS
This study is a randomized, open-label, multicenter and non-inferiority controlled clinical trial in China. Potential participants will be patients with pathologically confirmed endometrial cancer at the Zhejiang Cancer Hospital, Jiaxing Maternity and Child Health Care Hospital, and the First Hospital of Jiaxing in China. The total sample size for this study is 722. Patients will be randomly assigned in a 1:1 ratio to two groups. Patients in one group will undergo sentinel lymph node biopsy + total hysterectomy + bilateral salpingo-oophorectomy ± paraaortic lymph node resection. Patients in the other group will undergo sentinel lymph node biopsy + total hysterectomy + bilateral salpingo-oophorectomy + pelvic lymphadenectomy ± paraaortic lymph node resection. The 3-year disease-free survival rate, overall survival rate, quality of life (use EORTC QLQ-C30 + QLQ-CX24), and perioperative related indexes of the two groups will be compared.
RESULTS
We expect to find that for patients with early endometrial cancer, the 3-year disease-free survival rate following sentinel lymph node biopsy with indocyanine green combined with near-infrared fluorescence imaging is similar to that following lymphadenectomy. The operation time, as well as incidence of pelvic lymphocyst, lymphedema of lower limb, and edema of vulva in patients who only undergo sentinel lymph node biopsy are expected to be significantly lower than in patients who undergo lymphadenectomy. The quality of life of patients who undergo sentinel lymph node biopsy alone will be significantly better than that of patients who undergo lymph node dissection.
CONCLUSION
This will prove that the prognosis of sentinel lymph node biopsy alone with indocyanine green combined with near-infrared fluorescence imaging is not inferior to that of sentinel lymph node biopsy plus lymphadenectomy for early stage endometrial cancer with negative nodal assessment intraoperatively. In addition, sentinel lymph node biopsy alone with indocyanine green combined with near-infrared fluorescence imaging results in fewer surgical complications and gives patients better quality of life.

Comparative Study
INTRODUCTION
Endometrial carcinoma is the most common gynaecological malignancy. Studies have shown that laparoscopic total hysterectomy, bilateral salpingo-oophorectomy and pelvic lymph node dissection was advantageous compared to laparotomy in reducing length of stay and intraoperative blood loss. However, these studies had a predominantly Caucasian population. A comparison study was conducted among the Singapore population to investigate the differences in oncological and surgical outcomes between these two methods.
METHODS
A retrospective, single-centre cohort study was conducted. Records of hospitalised patients with Stage 1 endometrioid carcinoma from 2008 to 2014 were extracted for review. Demographic data and study-specific parameters, including operative time, length of hospitalisation, intraoperative and postoperative complications, pain scores, final staging and recurrence rates, were compared between the two groups.
RESULTS
475 endometrioid carcinoma patients were admitted for surgical staging, among whom 374 fulfilled our inclusion criteria. Out of these patients, 229 underwent laparotomy and 145 underwent laparoscopy. The race, parity and body mass index of both groups were comparable. Patients who underwent laparoscopic surgery reported reduced pain score within two hours postoperatively (p = 0.007) and at Postoperative Days 1, 2 and 3 (p < 0.001). Laparoscopic surgery also illustrated better outcomes such as reduced length of stay (p < 0.001) and reduced intraoperative blood loss (p < 0.001). The operative time, recurrence rate and disease-free intervals were comparable between both groups.
CONCLUSION
Laparoscopy offered similar oncological outcomes with superior surgical outcomes compared to laparotomy. It provides a suitable alternative in the surgical staging of endometrioid carcinoma.

OBJECTIVES:
To evaluate the postoperative pathological characteristics of hysterectomy specimens, preoperative cancer antigen (CA)-125 levels and imaging modalities in patients with endometrial cancer and to build a risk matrix model to identify and recruit patients for retroperitoneal lymphadenectomy.
METHODS:
A total of 405 patients undergoing surgical treatment for endometrial cancer were retrospectively reviewed and analyzed. Clinical (age and body mass index), laboratory (CA-125), radiological (lymph node evaluation), and pathological (tumour size, grade, lymphovascular space invasion, lymph node metastasis, and myometrial invasion) parameters were used to test the ability to predict lymph node metastasis. Four parameters were selected by logistic regression to create a risk matrix for nodal metastasis.
RESULTS:
Of the 405 patients, 236 (58.3%) underwent complete pelvic and para-aortic lymphadenectomy, 96 (23.7%) underwent nodal sampling, and 73 (18%) had no surgical lymph node assessment. The parameters predicting nodal involvement obtained through logistic regression were myometrial infiltration >50%, lymphovascular space involvement, pelvic lymph node involvement by imaging, and a CA-125 value >21.5 U/mL. According to our risk matrix, the absence of these four parameters implied a risk of lymph node metastasis of 2.7%, whereas in the presence of all four parameters the risk was 82.3%.
CONCLUSION:
Patients without deep myometrial invasion and lymphovascular space involvement on the final pathological examination and with normal CA-125 values and lymph node radiological examinations have a relatively low risk of lymph node involvement. This risk assessment matrix may be able to refer patients with high-risk parameters necessitating lymphadenectomy and to decide the risks and benefits of lymphadenectomy.

Review
Trachelectomy: How is it actually done? A review from FRANCOGYN group Titre: Trachélectomie: comment faire en pratique ? Revue de la littérature par le groupe FRANCOGYN.
Because of the peak incidence of cervical cancer between the ages of 35 and 44 and the increasing age of first pregnancy, the issue of fertility preservation in cases of early-stage cervical cancer in women in this reproductive age category arises. Early-stage cervical cancer patients have a good prognosis and are surgically treated in cases of mildly aggressive human papillomavirus-related histological type (squamous cell carcinoma, adenocarcinoma), FIGO stage IA to IB1 (i.e., <2 cm), with shallow stromal invasion (<10 mm) and without the presence of lymph-vascular space invasion or lymph node or regional involvement. Under these conditions, conservative treatment by trachelectomy, which has recurrence-free and overall survival rates equivalent to that of hysterectomy, may be considered. After a complete pre-therapeutic assessment, including pelvic lymphadenectomy, to eliminate all contraindications to conservative treatment, a simple or enlarged trachelectomy can be chosen. According to some authors, the route of entry (vaginal, simple or robot-assisted laparoscopy, laparotomy) has no significant effect on survival or fertility, although the literature on the subject is limited. Trachelectomy offers good results in terms of fertility, with an estimated pregnancy rate of between 23% and 55% and a live birth rate of 70%. The significant reduction of the cervix associated with the procedure increases the risk of prematurity. However, this can be prevented by the use of a permanent cerclage. Close follow-up of these patients is essential for a minimum period of 5 years in order to detect any recurrence or postoperative complications.

Clinical Trial
After pelvic lymphadenectomy (PLA), pelvic vessels, nerve, and ureter are skeletonized. Internal hernias beneath the skeletonized pelvic structure following pelvic lymphadenectomy (IBSPP) are a rare complication following PLA. To the best of our knowledge, only 12 IBSPP cases have been reported and clinical details on such hernias remain unknown. The aim of the study was to investigate the incident and etiology of IBSPP. 1313 patients who underwent open or laparoscopic pelvic lymphadenectomy were identified from our database. A retrospective review was performed. Mean follow-up period was 33.9 months. A total of 12 patients had IBSPP. Multivariate analysis of laparoscopic surgeries group as compared to open surgeries group, para-aortic lymphadenectomy rate, number of dissected lymph nodes by PLA, antiadhesive material use rate, and blood loss were lower in laparoscopic surgeries group: odd ratio (OR) = 0.13 [95% confidence interval (CI) 0.08-0.19], and OR = 0.70 [95% CI 0.50-0.99], OR = 0.17 [95% CI 0.10-0.28], OR = 0.93 [95% CI 0.92-0.94]. However, no significant difference was observed in the incidence of IBSPP between laparoscopic surgery (1.0%) and open surgery (0.8%). All IBSPP occurred in the right pelvic space. These findings may contribute to the development of prevention methods for this disease.

Multicenter study comparing oncologic outcomes after lymph node assessment via a sentinel lymph node algorithm versus comprehensive pelvic and paraaortic lymphadenectomy in patients with serous and clear cell endometrial carcinoma.
OBJECTIVES
To compare survival after nodal assessment using a sentinel lymph node (SLN) algorithm versus comprehensive pelvic and paraaortic lymphadenectomy (LND) in serous or clear cell endometrial carcinoma, and to compare survival in node-negative cases.
METHODS
Three-year recurrence-free survival (RFS) and overall survival were compared between one institution that used comprehensive LND to the renal veins and a second institution that used an SLN algorithm with ultra-staging with inverse-probability of treatment weighting (IPTW) derived from propensity scores to adjust for covariate imbalance between cohorts.
RESULTS
214 patients were identified (118 SLN cohort, 96 LND cohort). Adjuvant therapy differed between the cohorts; 84% and 40% in the SLN and LND cohorts, respectively, received chemotherapy ± radiation therapy. The IPTW-adjusted 3-year RFS rates were 69% and 80%, respectively. The IPTW-adjusted 3-year OS rates were 88% and 77%, respectively. The IPTW-adjusted hazard ratio (HR) for the association of surgical approach (SLN vs LND) with progression and death was 1.46 (95% CI: 0.70-3.04) and 0.44 (95% CI: 0.19-1.02), respectively. In the 168 node-negative cases, the IPTW-adjusted 3-year RFS rates were 73% and 91%, respectively. The IPTW-adjusted 3-year OS rates were 88% and 86%, respectively. In this subgroup, IPTW-adjusted HR for the association of surgical approach (SLN vs LND) with progression and death was 3.12 (95% CI: 1.02-9.57) and 0.69 (95% CI: 0.24-1.95), respectively.
CONCLUSION
OS was not compromised with the SLN algorithm. SLN may be associated with a decreased RFS but similar OS in node-negative cases despite the majority receiving chemotherapy. This may be due to differences in surveillance.
