Objectives Laparoscopy is commonly used for endometrial cancer treatment, and sentinel lymph node (SLN) mapping has become the standard procedure for nodal assessment. Despite the standardization of the technique, there is no definitive data regarding its failure rate. The objective of this study is to identify factors associated with unsuccessful SLN mapping in endometrial cancer patients undergoing laparoscopic SLN mapping after intracervical indocyanine green (ICG) injection. Methods We retrospectively evaluated a consecutive series of endometrial cancer patients who underwent laparoscopic SLN mapping with intracervical ICG injection, in four oncological referral centers from January 2016 to July 2019. Inclusion criteria were biopsy- proven endometrial cancer, total laparoscopic approach, and intracervical ICG injection. Exclusion criteria were evidence of lymph node involvement or extrauterine disease at preoperative imaging, synchronous invasive cancer, the use of tracers different from ICG, and the use of neoadjuvant treatment. Bilateral and failed bilateral SLN mapping groups were compared for clinical and pathological features. In patients with an unsuccessful procedure, side- specific lymphadenectomy was performed. Logistic regression was used to identify predictors of failure. Results A total of 376 patients were included in the study. The overall bilateral and unilateral SLN detection rates were 96.3%, 76.3%, and 20.0% respectively. The failed bilateral mapping detection rate was 23.7%. The median number of sentinel nodes removed was 2.2 (range, 0-5). After multivariate analysis, lymph vascular space involvement [OR 2.4 (1.04-1.12), P=0.003], nonendometrioid histology [OR 3.0 (1.43-6.29), P=0.004], and intraoperative finding of enlarged lymph node [OR 2.3 (1.01-5.31), P=0.045] were identified as independent predictors of failure of SLN mapping. Conclusion Lymph vascular space involvement, nonendometrioid histology, and intra- operative finding of enlarged lymph nodes were identified as independent risk factors for unsuccessful mapping in patients undergoing laparoscopic SLN mapping.

Objectives Pelvic side wall infiltration by gynecological malignancies has been considered for a long time an absolute contraindication to curative resection. The development of the laterally extended endopelvic resection (LEER) has challenged this surgical paradigm. Although the LEER has been standardized in open surgery, only small studies have been published about its endoscopic feasibility. The objective of this study is to analyze the safety of LEER in patients with gynecological malignancies involving the pelvic side wall. Methods We retrospectively evaluated a consecutive series of patients who underwent a laparoscopically modified LEER between July 2014 and November 2018. This indicated gynecological tumors involving the pelvic sidewall and surgeries were conducted in two Italian institutions. All patients underwent pre- operative CT scan or PET to evaluate for distant metastases. Patients without suspicioun of distant metastasis underwent pelvic MRI and examination under anesthesia to establish the resectability of the disease and concomitant diagnostic laparoscopy to exclude intraperitoneal dissemination. All women with disease- free interval <6 months, and/or performance status ≥ 2 ECOG were excluded. Type of resection was defined based on the status of the pathologic margins: R0, microscopically negative (free margin ≤ 5 mm); R1, microscopically positive; and R2, macroscopically (grossly) positive. Disease- free survival was calculated from the date of primary surgery to the time of recurrence. Overall survival was defined as the time from primary surgery to death. results Overall, 39 patients underwent a laparoscopic LEER and 18 (46.2%) patients were eligible for a laparoscopic approach. Laparoscopic LEER was performed as primary treatment for newly diagnosed tumors in eight patients (44.4%), and for recurrences in the other 10 patients (55.6%). No laparotomic conversions were registered. R0 resection was achieved with negative margins in all patients. The median operative time was 415 min (range, 285-615), median estimated blood loss was 285 mL (range, 100-600), and the median length of hospital stay was 10 days (range; 4-22). Only four patients (22.2%) needed blood intraoperative transfusion. In seven patients (38.9%), post- operative admission to intensive care unit was required. There were three (16.7%) intraoperative complications, all managed laparoscopically. In total there were six (33.3%) major postoperative complications: three patients (16.7%) experienced moderate hydronephrosis with normal renal function, which required temporary placement of nephrostomy; one patient (5.6%) had permanent urinary retention; and two patients (11.1%) had a reoperation, one for post- operative hemoperitoneum and another for complete vaginal cuff dehiscence. Discussion Laparoscopic LEER can be safely performed by experienced laparoscopic surgeons, in carefully selected patients with gynecological malignancies involving the lateral pelvic side wall, even for those in which a bladder and rectum sparing surgery appears possible. Further larger prospective trials are needed to evaluate the oncological and the long- term functional outcomes. [ABSTRACT FROM AUTHOR]

Introduction Sentinel lymph node (SLN) dissection has been recognized as a valid tool for staging in patients with endometrial cancer. Several factors are predictors of recurrence and survival in endometrial cancer, including positive lymphovascular space invasion. The aim of this study is to formulate a pre-operative score that, in the event of no-SLN identification, may give an estimate of the true probability of lymphovascular space invasion and guide management. Methodology This was a multi-institutional retrospective study conducted from January 2007 to December 2017. We included all patients with any grade endometrial tumor with a complete pathological description of the surgical specimen and with a minimum follow-up of 12 months. All patients underwent a class A hysterectomy according to Querleu and Morrow and bilateral salpingo-oophorectomy. Lymphadenectomy was performed based on patient risk of node metastases. In order to verify the predictive capacity of the parameters associated with lymphovascular space invasion status, grading, abnormal CA125 (>35 units/ml), myometrial invasion, and tumor size, a synthetic score was calculated. The score was introduced in the receiver operating characteristic curve model in which the binary classifier was represented by the lymphovascular space invasion status. The ideal cut-off was calculated with the determination of the Youden index. Sensitivity and negative predictive value of lymphovascular space invasion score was calculated in patients with lymph node metastasis. Results Six hundred and fourteen patients were included in the study. The average age and BMI of patients were 64.8 (range 33-88) years and 30.1 (range 17-64) respectively. Of the 284 patients who underwent lymphadenectomy, 231 (81.3%) patients had no lymph node metastases, 33 (11.6%) patients had metastatic pelvic lymph nodes, 12 (4.2%) patients had metastatic aortic lymph nodes, and eight (2.8%) patients had both pelvic and aortic metastatic lymph nodes. Lymphovascular space invasion was associated with deep myometrial infiltration (P<0.001), G3 grading (P<0.001), tumor size ≥25 mm (P=0.012), abnormal CA125 (P<0.001), recurrence (P<0.001), overall survival (P<0.001), and disease-free survival (P<0.01). Of all patients with lymphovascular space invasion, 79% had an lymphovascular space invasion score ≥5. The score ranged from a minimum score of 1 to a maximum of 7. The score shows 78.9% sensitivity (95% CI 0.6971 to 0.8594), 65.3% specificity (95% CI 0.611 to 0.693), 29.4% positive predictive value (95% CI 0.241 to 0.353), and 94.4% negative predictive value (95% CI 0.916 to 0.964). Conclusion We found that when lymphovascular space invasion score ≤4, there is a very low possibility of finding lymph nodal involvement. The preoperative lymphovascular space invasion score could complement the SLN algorithm to avoid unnecessary lymphadenectomies. [ABSTRACT FROM AUTHOR]

Objectives Survival of patients with cervical cancer is strongly associated with the local extent of the primary disease. The aim of the study was to develop an integrated diagnostic algorithm, including ultrasonography (USG), magnetic resonance imaging (MRI), and examination under anesthesia, to define the local extent of disease in patients with newly diagnosed cervical cancer. Methods Patients with biopsy proven cervical cancer who underwent primary surgery from January 2013 to December 2018 in four participating centers were recruited. Patients who underwent USG, MRI, and examination under anesthesia prior to surgery were included in the study. Those for whom complete data were not available were excluded. Data regarding tumor size, parametrial invasion, and vaginal involvement obtained by USG, MRI, and examination under anesthesia were retrieved and compared with final histology. Specificity and sensitivity of the three methods were calculated for each parameter and the methods were compared with each other. An integrated pre-surgical algorithm was constructed considering the accuracy of each diagnostic method for each parameter. Results A total of 79 consecutive patients were included in the study. Median age was 53 years (range 28-87) and median body mass index was 24.6 l2 cm and p=0.006 for tumors >4 cm) and vaginal involvement (p=0.01). There was no difference in detection of parametrial invasion between USG, MRI, and examination under anesthesia (p=0.26). Furthermore, regarding tumor size assessment, USG was found to be the significantly better method (p<0.01 for tumors >2 cm and p=0.02 for tumors >4 cm). Examination under anesthesia was the most accurate method for detection of vaginal involvement (p=0.01). Examination under anesthesia and MRI had higher accuracy than USG for identification of parametrial invasion. Application of the algorithm provided the correct definition of local extent of disease in 77.2% of patients (p=0.04). USG was the most accurate method to determine tumor size, while examination under anesthesia was found to be more accurate in prediction of vaginal involvement. Conclusion Our integrated diagnostic algorithm allows a higher accuracy in defining the local extent of disease and may be used as a tool to determine the therapeutic approach in women with cervical cancer.

Objective: To determine the incidence of long term lymphadenectomy complications in primary surgery for endometrial cancer and to elucidate risk factors for these complications. Methods: A retrospective chart review was carried out for all patients with endometrial cancer managed at Parma University Hospital Unit of Gynecology and Obstetrics between 2010 and 2016. Inclusion criteria were surgical procedure including hysterectomy and lymphadenectomy (pelvic or pelvic and aortic). We identified patients with postoperative lymphocele and lower extremity lymphedema. Logistic regression analysis was used to identify predictive factors for postoperative complications. Results: Of the 249 patients tested, 198 underwent pelvic lymphadenectomy (79.5%), and 51 (20.5%) of those underwent both pelvic and para-aortic lymphadenectomy. Among the 249 patients, 92 (36.9 %) developed lymphedema while 43 (17.3%) developed lymphocele. Multivariate analysis showed that addition of para-artic lymphadenectomy was an independent predictor for both lymphedema (odds ratio (OR) 2.764, 95% confidence interval (CI) 1.023 to 7.470) and lymphocele (OR 5.066, 95% CI 1.605 to 15.989). Moreover, postoperative adjuvant radiotherapy (OR 2.733, 95% CI 1.149 to 6.505) and identification of any positive lymph node (OR 19.391, 95% CI 1.486 to 253.0) were significantly correlated with lymphedema, while removal of circumflex iliac nodes (OR 8.596, 95% CI 1.144 to 65.591) was associated with lymphoceles occurrence. Conclusion: Although sentinel lymph node navigation is a promising option, lymphadenectomy represents the primary treatment in many patients with endometrial cancer. However, comprehensive nodal dissection remains associated with a high rate of long term complications, such as lymphedema and lymphocele. Avoiding risk factors that are related to the development of these postoperative complications is often difficult and, therefore, the strategy to assess lymph nodal status in these women must be tailored to obtain the maximum results in terms of oncological and functional outcome.

Objective: The identification of patients with endometrial cancer (EC) at higher risk for relapse is critical to individualize and better tailor postoperative treatment. No evidence is available regarding the possible association between tumor size (TS) and the risk of local recurrence. The purpose of this study was to analyze the correlation between TS and risk/type of recurrence in EC patients, stratified according to the new European Society of Medical Oncology-European Society of Gynecological Oncology-European Society for Radiotherapy and Oncology classification. Methods: Data of patients with histologically proven EC who received primary surgical treatment between November 1999 and June 2015 were retrospectively retrieved from 5 institutions. Optimal TS cutoff was calculated using a receiver operating characteristic curve. Site of recurrence as a function of TS and groups of risk were analyzed. Local recurrence-free survival, recurrence-free survival, and overall survival were calculated using the Kaplan-Meier method. Results: Data of 1166 patients were analyzed. Among them, 514 (44.1%) had low-risk EC, 174 (14.9%) had intermediate risk EC, 173 (14.8%) had high–intermediate risk EC, and 305 (26.2%) had high-risk EC. A total of 134 (11.5%) women had recurrence: 47 (4%) of them had local relapse, 30 (2.6%) had locoregional relapse, and 57 (4.9%) had distant relapse. Tumor size 25 mm or greater emerged as the threshold for the prediction of a higher rate of local recurrence (P < 0.0001, hazard ratio = 18.2, P = 0.005) and a lower local recurrence-free survival and recurrence-free survival (P < 0.0001) only in patients with low-risk EC. There was no statistically significant correlation between TS and recurrence in the other risk groups. Conclusions: In this very large series, tumor size emerges as an independent prognostic factor of local recurrence in women with low-risk EC and could be a valuable additional criterion to personalize the treatment approach to these patients.

Objectives: This multicentric retrospective study investigates the early and long-termself-reported urinary, bowel, and sexual dysfunctions in early-stage cervical cancer patients who submitted to laparoscopic totalmesometrial resection (L-TMMR), total laparoscopic radical hysterectomy, vaginalassisted laparoscopic radical hysterectomy, and laparoscopic-assisted radical vaginal hysterectomy. Methods: Cervical cancer patients, FIGO (International Federation of Gynecology and Obstetrics) stage IA2YIB1/IIA1 who submitted to nerve-sparing radical hysterectomy were recruited. Pelvic functionswere assessed within 30 days (early outcome) and 12 months after surgery (long-term outcome). Results: Two hundred thirteen subjects receiving nerve-sparing radical hysterectomy were enrolled. Laparoscopic total mesometrial resection was performed in 46 patients (21.6%), total laparoscopic radical hysterectomy in 65 patients (30.5%), vaginal-assisted laparoscopic radical hysterectomy in 54 patients (25.4%), and laparoscopic-assisted radical vaginal hysterectomy in 48 women (22.5%). Operative timewas significantly lower in the L-TMMR group (240 minutes; range, 120Y670 minutes; P = 0.001). The overall perioperative complication rate was 11.3%, with no statistically significant differences among the 4 groups. Stress incontinence and sensation of bladder incomplete emptyingwere detected, respectively, in 54 patients (25.6%) and 65 patients (30.7%) with a significantly lower prevalence among those in the L-TMMR group, which resulted, respectively, in 11.1% (P = 0.022) and 13.3% (P= 0.036). The prevalence rates of constipation, sensation of incomplete bowel emptying, and effort during evacuation were significantly higher among those in the L-TMMR group, resulting in, respectively, 37% (P = 0.001), 42.3% (P = 0.012), and 50% (P = 0.039). One hundred forty-nine patients (70%) were sexually active. Fifty-eight women (38.9%) reported low enjoyment, 83 women (55.7%) medium enjoyment, and 8 women (5.4%) reported high enjoyment, without statistically significant differences among the 4 groups. Conclusions: Laparoscopic total mesometrial resection is associated with improved longterm urinary autonomic functions and worse gastrointestinal autonomic outcome. Further larger prospective trials are needed to evaluate both the oncological and functional outcomes in order to establish themost appropriate surgical approach for early-stage cervical cancer patients.
