ABSTRACT
BACKGROUND: After the publication of the Laparoscopic Approach to Cervical Cancer trial, the standard surgical approach for early-stage cervical cancer is open radical hysterectomy. Only limited data were available regarding whether the change to open abdominal hysterectomy observed after the Laparoscopic Approach to Cervical Cancer trial led to an increase in postoperative complication rates as a consequence of the decrease in the use of the minimally invasive approach. OBJECTIVE: This study aimed to analyze whether there was a correlation between the publication of the Laparoscopic Approach to Cervical Cancer trial and an increase in the 30-day complications associated with surgical treatment of invasive cervical cancer. STUDY DESIGN: Data from the American College of Surgeons National Surgical Quality Improvement Program were used to compare the results in the pre-Laparoscopic Approach to Cervical Cancer period (January 2016 to December 2017) vs the results in the post-Laparoscopic Approach to Cervical Cancer period (January 2019 to December 2020). The rates of each surgical approach (open abdominal or minimally invasive) hysterectomy for invasive cervical cancer during the 2 periods were assessed. Subsequently, 30-day major complication, minor complication, unplanned hospital readmission, and intra- or postoperative transfusion rates before and after the publication of the Laparoscopic Approach to Cervical Cancer trial were compared. RESULTS: Overall, 3024 patients undergoing either open abdominal hysterectomy or minimally invasive hysterectomy for invasive cervical cancer were included in the study. Of the patients, 1515 (50.1%) were treated in the pre-Laparoscopic Approach to Cervical Cancer period, and 1509 (49.9%) were treated in the post-Laparoscopic Approach to Cervical Cancer period. The rate of minimally invasive approaches decreased significantly from 75.6% (1145/1515) in the pre-Laparoscopic Approach to Cervical Cancer period to 41.1% (620/1509) in the post-Laparoscopic Approach to Cervical Cancer period, whereas the rate of open abdominal approach increased from 24.4% (370/1515) in the pre-Laparoscopic Approach to Cervical Cancer period to 58.9% (889/1509) in the post-Laparoscopic Approach to Cervical Cancer period (P<.001). The overall 30-day major complications remained stable between the pre-Laparoscopic Approach to Cervical Cancer period (85/1515 [5.6%]) and the post-Laparoscopic Approach to Cervical Cancer period (74/1509 [4.9%]) (adjusted odds ratio, 0.85; 95% confidence interval, 0.61-1.17). The overall 30-day minor complications were similar in the pre-Laparoscopic Approach to Cervical Cancer period (103/1515 [6.8%]) vs the post-Laparoscopic Approach to Cervical Cancer period (120/1509 [8.0%]) (adjusted odds ratio, 1.17; 95% confidence interval, 0.89-1.55). The unplanned hospital readmission rate remained stable during the pre-Laparoscopic Approach to Cervical Cancer period (7.9% per 30 person-days) and during the post-Laparoscopic Approach to Cervical Cancer period (6.3% per 30 person-days) (adjusted hazard ratio, 0.78; 95% confidence interval, 0.58-1.04)]. The intra- and postoperative transfusion rates increased significantly from 3.8% (58/1515) in the pre-Laparoscopic Approach to Cervical Cancer period to 6.7% (101/1509) in the post-Laparoscopic Approach to Cervical Cancer period (adjusted odds ratio, 1.79; 95% confidence interval, 1.27-2.53). CONCLUSION: This study observed a significant shift in the surgical approach for invasive cervical cancer after the publication of the Laparoscopic Approach to Cervical Cancer trial, with a reduction in the minimally invasive abdominal approach and an increase in the open abdominal approach. The change in surgical approach was not associated with an increase in the rate of 30-day major or minor complications and unplanned hospital readmission, although it was associated with an increase in the transfusion rate.

Cervical cancer is a major global health issue, ranking as the fourth most common cancer in women worldwide. Depending on stage, histology, and patient factors, the standard management of cervical cancer is a combination of treatment approaches, including (fertility- or non-fertility-sparing) surgery, radiotherapy, platinum-based chemotherapy, and novel systemic therapies such as bevacizumab, immune checkpoint inhibitors, and antibody-drug conjugates. While ambitious global initiatives seek to eliminate cervical cancer as a public health problem, the management of cervical cancer continues to evolve with major advances in imaging modalities, surgical approaches, identification of histopathological risk factors, radiotherapy techniques, and biomarker-driven personalized therapies. In particular, the introduction of immune checkpoint inhibitors has dramatically altered the treatment of cervical cancer, leading to significant survival benefits in both locally advanced and metastatic/recurrent settings. As the landscape of cervical cancer therapies continues to evolve, the aim of the present review is to provide a comprehensive discussion of the current state and the latest practice-changing updates in cervical cancer.
ABSTRACT
OBJECTIVES: To assess predictors of extensive lymph node dissemination and non-vaginal recurrence in patients with endometrial cancer with positive sentinel lymph nodes (SLNs). METHODS: Patients with endometrial cancer who underwent primary surgery with SLN mapping and had at least one positive node between October 2013 and May 2019 were included. Positive SLNs were reviewed, and cases were classified according to the location of the metastasis (extracapsular vs intracapsular), and the size of the largest SLN metastasis (isolated tumor cells, micrometastasis, macrometastasis). Associations were assessed based on fitting logistic regression models and Cox proportional hazards models. RESULTS: A total of 103 patients met the inclusion criteria: including 36 (34.9%) with isolated tumor cells, 27 (26.2%) with micrometastasis, and 40 (38.8%) with macrometastasis. Notably, 71.4% of patients exhibiting extracapsular SLN metastases had multiple positive SLNs (p=0.008). Extracapsular invasion (adjusted odds ratio (aOR) 5.81, 95% CI 1.4 to 23.6) and age (aOR=1.8, 95% CI 1.1 to 3.0) emerged as independent predictors of multiple positive SLNs. Among the 38 patients who underwent a backup pelvic lymphadenectomy, 18 (47.4%) presented with positive pelvic non-SLNs, a phenomenon more prevalent in patients with macrometastasis (p=0.004).Independent predictors of non-vaginal recurrence included SLN macrometastasis (adjusted hazard ratio (aHR) 3.3, 95% CI 1.3 to 8.3), non-endometrioid histology (aHR=3.7, 95% CI 1.5 to 9.3), and cervical stromal invasion (aHR=5.5, 95% CI 2.0 to 14.9). Among the 34 patients with isolated tumor cells and endometrioid histology, 3 (9%) experienced a recurrence, all of whom had not received any adjuvant chemotherapy or external beam radiotherapy. CONCLUSION: Patients with positive SLN macrometastasis are independently associated with extensive lymphatic dissemination and distant recurrences. The risk of multiple positive SLNs increases with the extracapsular location of the SLN metastasis and with age. Independent uterine pathologic predictors of non-vaginal recurrence are non-endometrioid histology and cervical stromal invasion.

OBJECTIVE: To assess the distribution of molecular classes and their impact on the risk of recurrence in endometrial cancer patients with lymph node metastasis at the time of primary surgery. METHODS: Endometrial cancer patients with lymph node micrometastasis or macrometastasis (International Federation of Gynecology and Obstetrics (FIGO) 2009 stage IIIC) after surgical staging at five referral centers worldwide from October 2013 to September 2022 who underwent molecular classification were identified. Endometrial cancers were categorized into four molecular classes: POLE mutated, mismatch repair deficient, p53 abnormal, and no specific molecular profile. Survival analyses using Kaplan-Meier and Cox models (univariate and multivariate) were conducted to evaluate the relationship between molecular class and 5-year recurrence free survival. RESULTS: 131 patients were included: 55 (42.0%) no specific molecular profile, 46 (35.1%) mismatch repair deficient, 1 (0.8%) POLE mutated, and 29 (22.1%) p53 abnormal. During a 5 year follow-up period, 50 (38.2%) patients experienced a recurrence with a median time of 1.2 years (interquartile range (IQR) 0.5-1.8). Median follow-up for the remaining 81 patients was 3.1 years (IQR 1.3-4.5). Survival analysis revealed a significant difference in recurrence-free survival between no specific molecular profile, mismatch repair deficient, and p53 abnormal classes (log rank p<0.01). In a model adjusted for type of lymph node metastasis and tumor grade, the molecular class did not retain significance (p=0.13), while in a model adjusted for type of lymph node metastasis and adjuvant therapy, the molecular class retained significance (p<0.01). CONCLUSION: Among patients with stage IIIC endometrial cancer, POLE mutated tumors exhibited an extremely low prevalence, with no specific molecular profile emerging as the largest molecular subgroup. Despite the significant difference in recurrence-free survival between molecular classes, conventional histopathologic parameters retained crucial prognostic value. Our findings highlight the necessity of integrating molecular classes with pathological characteristics, rather than considering them in isolation as crucial prognostic factors in stage IIIC endometrial cancer.
ABSTRACT
OBJECTIVE: Ultrastaging is accurate in detecting nodal metastases, but increases costs and may not be necessary in certain low-risk subgroups. In this study we examined the risk of nodal involvement detected by sentinel lymph node (SLN) biopsy in a large population of apparent early-stage endometrial cancer and stratified by histopathologic characteristics. Furthermore, we aimed to identify a subgroup in which ultrastaging may be omitted. METHODS: We retrospectively included patients who underwent SLN (with bilateral mapping and no empty nodal packets on final pathology) ± systematic lymphadenectomy for apparent early-stage endometrial cancer at two referral cancer centers. Lymph node status was determined by SLN only, regardless of non-SLN findings. The incidence of macrometastasis, micrometastasis, and isolated tumor cells (ITC) was measured in the overall population and after stratification by histotype (endometrioid vs serous), myometrial invasion (none, <50%, ≥50%), and grade (G1, G2, G3). RESULTS: Bilateral SLN mapping was accomplished in 1570 patients: 1359 endometrioid and 211 non-endometrioid, of which 117 were serous. The incidence of macrometastasis, micrometastasis, and ITC was 3.8%, 3.4%, and 4.8%, respectively. In patients with endometrioid histology (n=1359) there were 2.9% macrometastases, 3.2% micrometastases, and 5.3% ITC. No macro/micrometastases and only one ITC were found in a subset of 274 patients with low-grade (G1-G2) endometrioid endometrial cancer without myometrial invasion (all <1%). The incidence of micro/macrometastasis was higher, 2.8%, in 708 patients with low-grade endometrioid endometrial cancer invading <50% of the myometrium. In patients with serous histology (n=117), the incidence of macrometastases, micrometastasis, and ITC was 11.1%, 6.0%, and 1.7%, respectively. For serous carcinoma without myometrial invasion (n=36), two patients had micrometastases for an incidence of 5.6%. CONCLUSIONS: Ultrastaging may be safely omitted in patients with low-grade endometrioid endometrial cancer without myometrial invasion. No other subgroups with a risk of nodal metastasis of less than 1% have been identified.

OBJECTIVES: Transvaginal ultrasound is typically the initial diagnostic approach in patients with postmenopausal bleeding for detecting endometrial atypical hyperplasia/cancer. Although transvaginal ultrasound demonstrates notable sensitivity, its specificity remains limited. The objective of this study was to enhance the diagnostic accuracy of transvaginal ultrasound through the integration of artificial intelligence. By using transvaginal ultrasound images, we aimed to develop an artificial intelligence based automated segmentation model and an artificial intelligence based classifier model. METHODS: Patients with postmenopausal bleeding undergoing transvaginal ultrasound and endometrial sampling at Mayo Clinic between 2016 and 2021 were retrospectively included. Manual segmentation of images was performed by four physicians (readers). Patients were classified into cohort A (atypical hyperplasia/cancer) and cohort B (benign) based on the pathologic report of endometrial sampling. A fully automated segmentation model was developed, and the performance of the model in correctly identifying the endometrium was compared with physician made segmentation using similarity metrics. To develop the classifier model, radiomic features were calculated from the manually segmented regions-of-interest. These features were used to train a wide range of machine learning based classifiers. The top performing machine learning classifier was evaluated using a threefold approach, and diagnostic accuracy was assessed through the F1 score and area under the receiver operating characteristic curve (AUC-ROC). RESULTS: 302 patients were included. Automated segmentation-reader agreement was 0.79±0.21 using the Dice coefficient. For the classification task, 92 radiomic features related to pixel texture/shape/intensity were found to be significantly different between cohort A and B. The threefold evaluation of the top performing classifier model showed an AUC-ROC of 0.90 (range 0.88-0.92) on the validation set and 0.88 (range 0.86-0.91) on the hold-out test set. Sensitivity and specificity were 0.87 (range 0.77-0.94) and 0.86 (range 0.81-0.94), respectively. CONCLUSIONS: We trained an artificial intelligence based algorithm to differentiate endometrial atypical hyperplasia/cancer from benign conditions on transvaginal ultrasound images in a population of patients with postmenopausal bleeding.
ABSTRACT
OBJECTIVE: Sentinel lymph node mapping by intracervical indocyanine green injection is the preferred method for surgical staging in endometrial cancer. Adverse reactions to indocyanine green are extremely rare, and information about the safety of this tracer in patients with a history of other allergies, asthma, or comorbidities is limited. We aim to evaluate the rate of adverse reactions to indocyanine green injected during sentinel lymph node mapping in patients with endometrial cancer and review the etiology of such reactions. METHODS: All patients with endometrial cancer undergoing sentinel lymph node mapping with indocyanine green cervical stroma injection at the Mayo Clinic in Rochester, Minnesota between June 2014 and December 2018 were retrospectively evaluated. Any adverse reaction occurring intra-operatively or within 7 days after surgery was identified. A thorough chart review was performed by an allergy specialist physician for any patient with an allergic-type reaction. RESULTS: We included 923 patients of which 565 (61.2%) had a history of allergy to antibiotics, non-steroidal anti-inflammatory drugs (NSAIDs), other medications, and/or environmental exposures. Of 490 patients who had previously received contrast media, 25 (5.1%) had a history of an adverse reaction. No immediate anaphylaxis or other allergic reactions were observed after indocyanine green injection. 10 (1.1%) patients developed a transient skin reaction within 7 days after surgery. None of these patients had a history of contrast media reaction. Based on timing and clinical/peri-operative history of affected patients, it was determined that skin reactions were likely induced by other newly prescribed medications or contact sensitivity, not administration of indocyanine green. CONCLUSION: Indocyanine green injection for sentinel lymph node mapping in patients with endometrial cancer caused no immediate/delayed anaphylactic or other severe allergic reactions. This included patients with a history of other allergies, asthma, and comorbidities. The myth of iodine's relationship to allergic reactions must be refuted to allow indocyanine green use in patients with a history of contrast media or shellfish allergy.
ABSTRACT
OBJECTIVE: The prognostic significance of isolated tumor cells (≤0.2 mm) in sentinel lymph nodes (SLNs) of endometrial cancer patients is still unclear. Our aim was to assess the prognostic value of isolated tumor cells in patients with low risk endometrial cancer who underwent SLN biopsy and did not receive adjuvant therapy. Outcomes were compared with node negative patients. METHODS: Patients with SLNs-isolated tumor cells between 2013 and 2019 were identified from 15 centers worldwide, while SLN negative patients were identified from Mayo Clinic, Rochester, between 2013 and 2018. Only low risk patients (stage IA, endometrioid histology, grade 1 or 2) who did not receive any adjuvant therapy were included. Primary outcomes were recurrence free, non-vaginal recurrence free, and overall survival, evaluated with Kaplan-Meier methods. RESULTS: 494 patients (42 isolated tumor cells and 452 node negative) were included. There were 21 (4.3%) recurrences (5 SLNs-isolated tumor cells, 16 node negative); recurrence was vaginal in six patients (1 isolated tumor cells, 5 node negative), and non-vaginal in 15 (4 isolated tumor cells, 11 node negative). Median follow-up among those without recurrence was 2.3 years (interquartile range (IQR) 1.1-3.0) and 2.6 years (IQR 0.6-4.2) in the SLN-isolated tumor cell and node negative patients, respectively. The presence of SLNs-isolated tumor cells, lymphovascular space invasion, and International Federation of Obstetrics and Gynecology (FIGO) grade 2 were significant risk factors for recurrence on univariate analysis. SLN-isolated tumor cell patients had worse recurrence free survival (p<0.01) and non-vaginal recurrence free survival (p<0.01) compared with node negative patients. Similar results were observed in the subgroup of patients without lymphovascular space invasion (n=480). There was no difference in overall survival between the two cohorts in the full sample and the subset excluding patients with lymphovascular space invasion. CONCLUSIONS: Patients with SLNs-isolated tumor cells and low risk profile, without adjuvant therapy, had a significantly worse recurrence free survival compared with node negative patients with similar risk factors, after adjusting for grade and excluding patients with lymphovascular space invasion. However, the presence of SLNs-isolated tumor cells was not associated with worse overall survival.
ABSTRACT
STUDY OBJECTIVE: To show how advanced pelvic Schwannoma can be safely managed with a laparoscopic approach. DESIGN: Demonstration of the laparoscopic technique with narrated video footage. SETTING: Schwannomas are benign tumors that arise from well-differentiated Schwann cells (glial cells) of peripheral nerve sheaths. Schwannomas are nonaggressive, slow-growing, solitary masses with a low rate of malignant transformation and a low risk of recurrence after resection. They rarely occur in the pelvis, with a reported incidence of 1% to 3%. Tumors involving spinal nerve roots commonly present with radicular pain and nerve compression syndromes (Supplemental Video 1-3). This video shows the management of pelvic Schwannoma originating from the left sacral root S1 by a minimally invasive approach. INTERVENTIONS: Laparoscopic nerve-sparing excision of a pelvic Schwannoma. CONCLUSION: Historically, pelvic schwannomas have been managed mainly by laparotomy. Here, we demonstrate the feasibility and safety of a large pelvic Schwannoma excision by a minimally invasive approach.

BACKGROUND: Pheochromocytoma and Paraganglioma (PGL) are rare neuroendocrine tumors, with an estimated incidence of about 0.6 cases per 100.000 person/year. Overall, 3-8% of them are malignant. These tumors are characterized by a classic triad of symptoms (headaches, palpitations, profuse sweating) due to hypersecretion of catecholamines. Despite several advantages of minimally invasive surgery (MIS) for PGL debulking, the surgical approach is not standardized yet. In this scenario, we aimed to report a case of a multiple recurrent PGL with metastatic retroperitoneal localization involving the pelvic sidewall, excised with MIS. CASE PRESENTATION: We performed complete laparoscopic-assisted neuronavigation (LANN technique) with isolation of the sacral routes and the sciatic nerve to obtain complete exposure of the main anatomic landmarks. Robotic surgery was used to perform neurolysis of sacral plexus, and partial resection of left splanchnic nerves was needed. After the resection of the first mass, extensive neurolysis of all sacral routes, obturator nerve, pudendal nerve till the entrance of the pudendal (Alcock) canal, and sciatic nerve was performed. Finally, the mass was identified after trans gluteal incision and dissection of the maximum gluteal muscle, and a partial resection of the superior gluteal nerve and slicing of the sciatic nerve were needed to obtain a radical excision of the mass. Then neurorrhaphy of the sectioned nerve fibers of the superior gluteal nerve was performed, and nerve protection was obtained using a collagen nerve wrap. After 18 months of follow-up, the patient is free of disease at the MRI imaging and 123I-metaiodobenzylguanidine scintigraphy. CONCLUSIONS: Minimally invasive gynecological surgery with neuropelveological approach could be considered as a feasible option in case of multifocal pelvic retroperitoneal malignant paraganglioma of the pelvic side wall.

STUDY OBJECTIVE: Resection of bulky lymph nodes in gynecologic oncology is a challenging procedure. Considering the risk of intraoperative vascular injury, a technique to avoid severe complications is mandatory. In this study, we aimed to analyze the feasibility of laparoscopic ultraradical lymph node debulking using Yasargil clamps in patients with gynecologic cancer with bulky lymph node metastases. DESIGN: Multicenter retrospective case series (ClinicalTrialg.gov ID: NCT05318170), between September 2010 and April 2020. SETTING: Units of Gynecologic Oncology. PATIENTS: Patients with gynecologic cancer with bulky lymph node metastases. INTERVENTIONS: Laparoscopic ultraradical lymph node debulking using Yasargil clamps. MEASUREMENTS AND MAIN RESULTS: Forty-three patients with gynecologic cancer with bulky pelvic and/or aortic lymph nodes metastases undergoing laparoscopic lymph node debulking surgery using Yasargil clamps were included. Median surgical time was 300 minutes (range, 120-550 minutes); median estimated blood loss was 170 mL (range, 0-700 mL). Median size of lymph nodes was 50 mm (range, 25-100). R0 resection was achieved in all cases. Four intraoperative complications (9.3%) occurred. No conversion to open surgery was required. There were 8 postoperative complications, classified grade 2 or worse. There were no cases with intra- or postoperative mortality. CONCLUSION: In our experience, in carefully selected patients with gynecologic cancer with bulky lymph nodes, laparoscopic lymph node debulking using Yasargil clamps could be considered a valid option to avoid potential severe vascular intraoperative complications.

INTRODUCTION: Squamous cell carcinoma (SCC) arising from endometriosis is very rare. Moreover, endometriosis located on the pelvic side wall is uncommon, while its cancerization is quite unusual. We herein report the first case of retroperitoneal SCC arising from endometriosis. CASE PRESENTATION: A case of a 52-year-old woman with retroperitoneal pararectal right mass is presented. The pelvic magnetic resonance imaging showed a retroperitoneal tumor extended to the right pelvic side wall. The neuropelveological examination completed the preoperative assessment, showing a right-sided sciatica and overactive bladder symptoms. Tumor removal was completely managed by a minimally invasive technique through the laparoscopic laterally extended endopelvic resection procedure and pelvic neurolysis. Final histology revealed a SCC in a context of diffuse endometriosis with a histologic continuity between the SCC and the endometriosis. The patient underwent adjuvant chemotherapy with no recurrence after 6 months. CONCLUSION: To the best of our knowledge, the present case represents the first evidence of retroperitoneal SCC of the pelvic side wall arising from endometriosis completely resected by laparoscopic approach. Although its rare occurrence, the gynecologist oncologist should maintain a high index of suspicion for malignant endometriosis transformation in case of retroperitoneal pelvic mass and history of endometriosis.

OBJECTIVE: Surgical demonstration of combined sacral plexus neurolysis and laparoscopic laterally extended endopelvic resection for deep lateral infiltrating endometriosis. DESIGN: Video showing principles of neurolysis and laparoscopic laterally extended endopelvic resection applied to endometriotic surgery. SETTING: University tertiary referral center. Deep infiltrating endometriosis is an underestimated disease with real medical and clinical issues, recently classified as central pelvic endometriosis and lateral pelvic endometriosis further divided into superficial and deep according to the structures' involvement [1]. The surgical removal of endometriotic foci remains the standard treatment. A wide knowledge of neuroanatomy and high skills in minimally invasive surgery are required to manage this challenging surgical scenario [2]. INTERVENTIONS: New surgical approach for deep lateral infiltrating endometriosis based on the principles of lateral extended endopelvic resection and neuropelviologic surgery [3,4]. The patient was a 35-year-old woman, para 1, with neuropathic pain radiating to the left leg and a cyclic menstrual disorder. A laparoscopically assisted neuronavigation and subsequent neurolysis allowed the identification of the lateral nodule without damage to the autonomic pelvic innervation [1]. Then, a complete resection of the internal vascular compartment was required to obtain a radical endometriotic eradication. Shaving and bladder resection were also performed to complete removal of the endometriotic foci. CONCLUSION: The association of neuroanatomic knowledge and surgical oncologic principles applied to minimally invasive surgery should be considered to ensure an adequate surgical radicality and clinical benefit in patients with deep infiltrating endometriosis.

STUDY OBJECTIVE: To demonstrate the application of surgical neuroanatomic principles for the diagnosis and treatment of deep infiltrating endometriosis involving the lateral femoral cutaneous nerve. DESIGN: Video demonstration of laparoscopic lateral femoral cutaneous endometriosis resection with nerve transplant. SETTING: Endometriosis infiltrating somatic nerves is a poorly known condition, which can cause severe neuropathic symptoms [1] and is often unrecognized with a subsequent treatment delay [1]. Intimate knowledge of pelvic neuroanatomy and expertise in minimally invasive surgery are essential to manage this challenging surgical scenario [2-4]. INTERVENTIONS: Thirty-six years old patient with primary infertility and chronic pelvic pain associated with dysmenorrhea, dyspareunia, dysuria, and dyschezia. Preoperative magnetic resonance imaging detected a 3-cm parauterine and a 2-cm retrocervical endometriosis nodule. Magnetic resonance imaging did not demonstrate pelvic nerve involvement. Preoperative neuropelveologic assessment demonstrated a significant hypoesthesia of the corresponding lateral femoral cutaneous nerve dermatome, representing the primary complaint. A swab test showed spotting areas of allodynia. These findings prompted us to investigate for a right lateral femoral cutaneous entrapment. Laparoscopy showed an endometriosis nodule infiltrating the right lateral femoral cutaneous nerve. A resection of the nerve was necessary, and a subsequent reconstruction with a collagen bovine neuro-guide was carried out. The operative time was 300 minutes, and the estimated blood loss was 150 mL. Hospital stay was 3 days. After 3 months, the patient showed a clinical improvement in the pain and hypoesthesia on the reconstructed nerve dermatome. CONCLUSION: Neuropelvic anatomic assessment should be considered during the preoperative evaluation for patients with endometriosis who have pelvic pain and neuropathy as part of the diagnostic process [5]. This unique case demonstrates that nerve resection and transplantation can be used in specific situations for neuropathy related to deep infiltrative endometriosis of pelvic nerves.

Lower extremity lymphedema (LEL) is a common complication following surgical staging of endometrial cancer. LEL is a chronic condition associated with significant impact on patient morbidity and quality of life (QoL). This review aimed to report the current evidence in the literature on secondary LEL after surgical staging for endometrial cancer, focusing on the incidence based on different approaches to lymph node staging, diagnosis, risk factors, and the impact on QoL. Due to the absence of a standardized agreement regarding the methodology for evaluating LEL, the documented frequency of occurrence fluctuates across different studies, ranging from 0% to 50%. Systematic pelvic lymphadenectomy appears to be the primary determinant associated with the emergence of LEL, whereas the implementation of sentinel lymph node biopsy has notably diminished the occurrence of this lymphatic complication after endometrial cancer staging. LEL is strongly associated with decreased QoL, lower limb function, and negative body image, and has a detrimental impact on cancer-related distress reported by survivors. Standardization of lymphedema assessment is needed, along with cross-cultural adaptation of subjective outcome measures for self-reported LEL. The advent of sentinel lymph node mapping represents the ideal approach for accurate nodal assessment with less short- and long-term morbidity. Further research is needed to definitively assess the prevalence and risk factors of LEL and to identify strategies to improve limb function and QoL in cancer survivors with this chronic condition.
