Concurrent endometrial cancer in atypical endometrial hyperplasia and the role of sentinel lymph nodes: clinical insights from a multicenter experience.

OBJECTIVE: This study aimed to evaluate the prevalence of concurrent endometrial cancer in patients pre-operatively diagnosed with atypical endometrial hyperplasia undergoing hysterectomy. Additionally, we assessed the occurrence of high to intermediate-risk and high-risk tumors according to the ESGO-ESTRO-ESP classification. The study also compared surgical outcomes and complications between patients undergoing simple hysterectomy and those undergoing hysterectomy with sentinel lymph node biopsy. METHODS: In this multicenter retrospective study, patients with a pre-operative diagnosis of atypical endometrial hyperplasia were identified and divided into two groups: Group 1, which included patients treated with total hysterectomy with or without bilateral salpingo-oophorectomy, and Group 2, where sentinel lymph node biopsy was incorporated into the standard surgical treatment. RESULTS: Among 460 patients with atypical endometrial hyperplasia, 192 received standard surgical management (Group 1) and 268 underwent sentinel lymph node biopsy (Group 2). A total of 47.2% (95% CI 42.6% to 51.7%) of patients were upgraded to endometrial cancer on final histopathological examination. High to intermediate-risk and high-risk tumors constituted 12.3% and 9.2% in Group 2 and 7.4% and 3.7% in Group 1. Lymph node metastases were identified in 7.6% of patients with concurrent endometrial cancer who underwent nodal assessment with at least unilateral mapping. Of the 12 sentinel lymph node metastases, 75.0% were micrometastases, 16.7% macrometastases, and 8.3% isolated tumor cells. No significant differences were found in estimated blood loss, operative time, and intra-operative and post-operative complications between the two groups. The rate of patients undergoing sentinel lymph node biopsy doubled every 2 years (OR 2.010, p<0.001), reaching 79.1% in the last 2 years. CONCLUSION: This study found a prevalence of concurrent endometrial cancer of 47.2%, and sentinel lymph node biopsy provided prognostic and therapeutic information in 60.8% of cases. It also allowed for the adjustment of adjuvant therapy in 12.3% of high to intermediate-risk patients without increasing operative time or complication rates.

Optimizing patient selection for secondary cytoreductive surgery in recurrent endometrial cancer.

OBJECTIVE: This retrospective, multicenter, observational study aimed to refine patient selection criteria for secondary cytoreductive surgery in recurrent endometrial cancer. The objective was to identify preoperative predictors of complete cytoreduction, assess surgical complexity, and propose a preoperative predictive scoring system to identify suitable candidates for secondary cytoreductive surgery. METHODS: Data from 331 women with recurrent endometrial cancer were analyzed across three Italian centers from January 2010 to December 2021. Patients were categorized based on treatment received (medical treatment, diagnostic laparoscopy/examination under anesthesia, or secondary cytoreductive surgery). Preoperative predictors, surgical complexity, complications, and a predictive scoring system were assessed. Logistic regression and receiver operating characteristic analysis were used for statistical evaluation. RESULTS: Of the cohort, 56.2% underwent debulking surgery, 17.2% had diagnostic laparoscopy, and 26.6% received medical treatment. Patients undergoing secondary cytoreductive surgery were younger, with a lower body mass index, better performance status, and fewer comorbidities. Single site locoregional relapse was common in secondary cytoreductive surgery patients. Age <65 years, single site relapse, lymph node, and hematogenous relapse were independent predictors of complete cytoreduction. A predictive scoring system demonstrated a clear relationship between the score and the likelihood of complete cytoreduction. CONCLUSION: This study identified age <65 years, single site recurrence, as well as nodal and hematogenous recurrence, as predictive factors for achieving optimal cytoreduction. A predictive scoring system incorporating these factors has been proposed to identify optimal candidates for secondary cytoreductive surgery in recurrent endometrial cancer. The scoring system showed promising predictive accuracy and could aid in refining the decision making process, ensuring appropriate patient selection for secondary cytoreductive surgery. Further prospective studies are warranted to validate and enhance the predictive model.

Molecular classification of endometrial carcinoma on endometrial biopsy: an early prognostic value to guide personalized treatment.

OBJECTIVE: Molecular features are essential for estimating the risk of recurrence and impacting overall survival in patients with endometrial cancer. Additionally, the surgical procedure itself could be personalized based on the molecular characteristics of the tumor. This study aims to assess the feasibility of obtaining reliable molecular classification status from biopsy specimens collected during hysteroscopy to better modulate the appropriate surgical treatment. METHODS: This monocentric, retrospective, observational study was conducted on 106 patients who underwent a biopsy procedure followed by radical surgery for endometrial cancer, with concurrent molecular investigation. The molecular classification was determined through immunohistochemical staining for p53 and mismatch repair proteins, along with gene sequencing for POLE. RESULTS: Overall, 106 patients underwent molecular investigation, which was finally achieved on 99 patients (93.4%). Among these, the molecular analysis was conducted in 71 patients (67%) on the pre-operative endometrial biopsy and on the final uterine specimen in 28 patients (26.4%). Most of the endometrial biopsies were performed using Bettocchi hysteroscopy (66%). Molecular analysis was not possible in seven patients (6.6%), with six cases due to sample inadequacy and one case attributed to intra-mucosal carcinoma. The molecular results showed that the copy number low sub-group was the most common, and five cases of 'multiple classifiers' were observed in the low-risk category. CONCLUSION: Our experience in obtaining molecular information from biopsy samples underscores the feasibility and efficacy of this technique, even in small tissue samples. This capability helps define the prognostic group of patients, facilitates timely decision-making, and develops a personalized strategy for each patient.

Major determinants of survival in recurrent endometrial cancer-the role of secondary cytoreductive surgery: a multicenter study.

OBJECTIVE: The main objective of the study was to assess the influence of different clinical and therapeutic variables on the oncological outcomes of patients with endometrial cancer relapse. In particular, we evaluated the impact of cytoreductive surgery with the achievement of complete gross resection. METHODS: This is a multicenter retrospective cohort study conducted in three centers in Italy and including all patients with first relapse of endometrial cancer from January 2010 to December 2021. RESULTS: Data from 331 women with recurrent endometrial cancer were analyzed. Secondary cytoreductive surgery was performed in 56.2% of cases (186 patients). Complete gross resection was achieved in 178 patients (95.7%). Complete gross resection conferred a statistically significant survival benefit both for post-relapse survival and post-relapse free survival (3 years post-relapse survival: 75.4% vs 56.4%, p<0.001; 3 years post-relapse free survival: 32.6% vs 26.5%, p=0.027). At multivariate Cox regression analysis, age ≥75 years, Eastern Cooperative Oncology Group Performance Status ≥2, the advanced-metastatic risk group, complete gross resection, and multiple site relapses were identified as independent significant predictors for post-relapse survival; regarding post-relapse free survival, only age ≥75, the high and advanced-metastatic risk groups, and complete gross resection confirmed their statistical significance. CONCLUSIONS: Secondary cytoreductive surgery with achievement of complete gross resection was confirmed to be an independent positive predictor for survival in patients with recurrent endometrial cancer and should be considered a valid primary treatment in the therapeutic decision-making process.

Long-term survival outcomes in high-risk endometrial cancer patients undergoing sentinel lymph node biopsy alone versus lymphadenectomy.

OBJECTIVE: Endometrial cancer is the most common gynecologic neoplasm. To date, international guidelines recommend sentinel lymph node biopsy for low-risk neoplasms, while systematic lymphadenectomy is still considered for high-risk cases. This study aimed to compare the long-term survival of high-risk patients who were submitted to sentinel lymph node biopsy alone versus systematic pelvic lymphadenectomy. METHODS: Patients with high-risk endometrial cancer according to the 2021 European Society of Gynaecological Oncology/European Society for Radiotherapy and Oncology/European Society of Pathology risk classification were retrospectively analyzed. The primary aim of the study was to compare the long-term overall survival and disease-free survival of high-risk endometrial cancer patients undergoing sentinel lymph node biopsy versus systematic lymphadenectomy. A supplementary post-hoc survival analysis of cases with nodal metastasis was performed to compare sentinel lymph node and lymphadenectomy survival outcomes in this subset of patients. RESULTS: The study enrolled 237 patients with histologically proven high-risk endometrial cancer. Patients were followed up for a median of 31 months (IQR 18-40). During the follow-up, 38 (16.0%) patients had a recurrence, and 19 (8.0%) patients died. Disease-free survival (85.2% vs 82.8%; p=0.74) and overall survival (91.3% vs 92.6%; p=0.62) were not different between the sentinel lymph node alone and lymphadenectomy groups. Furthermore, neither overall survival (96.1% vs 91.4%; p=0.43) nor disease-free survival (83.7% vs 76.4%; p=0.46) were different among sentinel lymph node alone and lymphadenectomy groups in patients with nodal metastasis. CONCLUSIONS: Sentinel lymph node mapping alone in high-risk endometrial cancer appears to be an oncologically safe technique over a long observational time. Systematic lymphadenectomy in this population does not offer a survival advantage.

Vibrational spectroscopies for biochemical investigation of X-ray exposure effects on SH-SY5Y human neuroblastoma cells.

Neuroblastoma is the most recurring cancer in childhood and adolescence. The SH-SY5Y neuroblastoma cell line is generally adopted for elaborating new therapeutical approaches and/or elaborating strategies for the prevention of central nervous system disturbances. In fact, it represents a valid model system for investigating in vitro the effects on the brain of X-ray exposure using vibrational spectroscopies that can detect early radiation-induced molecular alterations of potential clinical usefulness. In recent years, we dedicated significant efforts in the use of Fourier-transform and Raman microspectroscopy techniques for characterizing such radiation-induced effects on SH-SY5Y cells by examining the contributions from different cell components (DNA, proteins, lipids, and carbohydrates) to the vibrational spectra. In this review, we aim at revising and comparing the main results of our studies to provide a wide outlook of the latest outcomes and a framework for future radiobiology research using vibrational spectroscopies. A short description of our experimental approaches and data analysis procedures is also reported.

Post Treatment Sexual Function and Quality of Life of Patients Affected by Cervical Cancer: A Systematic Review.

Introduction: The aim of this study is to analyze the available scientific evidence regarding the quality of life (QoL) and sexual function (SF) in patients affected by cervical cancer (CC) after surgical and adjuvant treatments. Materials and Methods: Preliminary research was conducted via electronic database (MEDLINE, PubMed and Cochrane Library) with the use of a combination of the following keywords: SF, QoL, and CC. The principal findings considered in the present review were the study design, the number of patients included in each study, the information about the malignancy (histology and stage of disease), the questionnaires administered, and the principal findings concerning SF and QoL. Results: All studies were published between 2003-2022. The studies selected consisted of one randomized control study, seven observational studies (three prospective series), and nine case control studies. The scores used were focused on SF, QOL, fatigue, and psychological aspects. All studies reported a decreased SF and QOL. The most developed questionnaires were the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), the Female Sexual Function Index (FSFI), the Hospital Anxiety and Depression scale (HADS), and the Female Sexual Distress Scale (FSDS). Discussion: All studies reported a decreased SF and QOL. In addition to the perception of body image, several factors coexist in influencing the outcomes such as the physical, hormonal, psychological. Conclusions: Sexual dysfunction after CC treatment has a multifactorial aetiology which negatively affects the quality of life. For these reasons, it is important to follow and support patients with a multidisciplinary team (doctors, nurses, psychologists, dieticians) before and after therapy. This type of tailored therapeutic approach should become a standard. Women should be informed about possible vaginal changes and menopausal symptoms after surgery and on the positive effects of psychological therapy.

Exploring Surgical Strategies for Uterine Fibroid Treatment: A Comprehensive Review of Literature on Open and Minimally Invasive Approaches.

Background and Objectives: Uterine myomas represent one of the most prevalent pathologies affecting the female population. These benign neoplasms originate from the smooth muscular cells of the uterus, and they can be either single or multiple. Often associated with debilitating symptoms such as pelvic heaviness, pain, constipation, and urinary dysfunctions, the surgical management of myomectomy exhibits considerable variability. This diversity in approaches is influenced by factors such as the number and size of myomas, the patient's age, and overall clinical conditions. This study aims to elucidate and compare the advantages and disadvantages of different surgical approaches, specifically endoscopic procedures versus open surgery, providing valuable insights for clinical decision making. Materials and Methods: A comprehensive bibliographic search spanning from 2013 to 2023 was systematically conducted across databases including Medline, Embase, the Cochrane Database of Systematic Reviews, and ClinicalTrials.gov. The search utilized keywords such as "myomectomy laparoscopic and open", "myomectomy open and minimally invasive", "myomectomy open and laparoscopic", and "myomectomy open vs. laparoscopic." The research methodology, along with predetermined inclusion and exclusion criteria, was established prior to the search, ensuring a systematic and rigorous approach. Subsequently, data analysis was carried out. Results: Following the study selection process, 25 articles met the eligibility criteria for inclusion in this analysis. The average numbers of myomas were 3.7 (ranging from 1 to 13.7) and 5.4 (ranging from 1 to 13.5) for the minimally invasive surgery and open surgery groups, respectively. In terms of myoma size, the total averages across studies were 7 cm (ranging from 4.8 to 14) for the minimally invasive group and 8 cm (ranging from 3.9 to 11.2) for the open surgery group. The average pregnancy and delivery rates were 29.7% (ranging from 1.8 to 100) for the minimally invasive group and 28.5% (ranging from 1.8 to 100) for the open surgery group. Regarding complications, the average rate was 14.2% (ranging from 0 to 50) for the endoscopic group and 22.3% (ranging from 0 to 60.3) for the laparotomic group. Conclusions: In conclusion, a critical factor influencing the choice of surgical approach is primarily the size and quantity of fibroids. The mini-laparotomic approach emerges as a viable alternative to endoscopy, demonstrating favorable surgical outcomes and aesthetic results. Interestingly, the type of surgical procedure appears to have no significant impact on the pregnancy rate.

Predictive Score of Nodal Involvement in Endometrial Cancer Patients: A Large Multicentre Series.

BACKGROUND: Sentinel lymph node (SLN) biopsy is considered the standard of care in early-stage endometrial cancer (EC). For SLN failure, a side-specific lymphadenectomy is recommended. Nevertheless, most hemipelvises show no nodal involvement. The authors previously published a predictive score of lymphovascular involvement in EC. In case of a negative score (value 3-4), the risk of nodal metastases was extremely low. This multicenter study aimed to analyze a predictive score of nodal involvement in EC patients. METHODS: The study enrolled patients with EC who had received comprehensive surgical staging with nodal assessment. A preoperative predictive score of nodal involvement was calculated for all the patients before surgery. The score included myometrial infiltration, tumor grading (G), tumor diameter, and Ca125 assessment. The STARD (standards for Reporting Diagnostic accuracy studies) guidelines were followed for score accuracy. RESULTS: The study analyzed 1038 patients and detected 155 (14.9%) nodal metastases. The score was negative (3 or 4) for 475 patients and positive (5-7) for 563 of these patients. The score had a sensitivity of 83.2%, a specificity of 50.8%, a negative predictive value of 94.5%, and a diagnostic value of 55.7%. The area under the curve was 0.75. The logistic regression showed a significant correlation between a negative score and absence of nodal metastasis (odds ration [OR], 5.133, 95% confidence interval [CI], 3.30-7.98; p < 0.001). CONCLUSION: The proposed predictive score is a useful test to identify patients at low risk of nodal involvement. In case of SLN failure, the application of the current score in the SLN algorithm could allow avoidance of unnecessary lymphadenectomies.

Impact of Obesity on Sentinel Lymph Node Mapping in Patients with apparent Early-Stage Endometrial Cancer: The ObeLyX study.

OBJECTIVE: Conflicting data exists on the impact of Body Mass Index (BMI) on sentinel lymph-node (SLN) detection. The primary study endpoint was to investigate the impact of obesity on overall detection rate, bilateral mapping, and mapping failure rate of SLN. In addition, we evaluated possible differences in terms of surgical management and "empty-packet dissection" rate among obese and non-obese patients. METHODS: Multicenter, propensity-matched, retrospective study. Patients with apparent early-stage endometrial cancer were included. Study population was divided into women with BMI

Anatomical distribution of sentinel lymph nodes in patients with endometrial cancer: a multicenter study.

OBJECTIVE: Sentinel lymph node (SLN) mapping represents the standard approach in uterine confined endometrial cancer patients. The aim of this study was to evaluate the anatomical distribution of SLNs and the most frequent locations of nodal metastasis. METHODS: This was an observational retrospective multicenter study involving eight high volume gynecologic cancer centers in Italy. We reviewed 1576 patients with a histologically confirmed diagnosis of endometrial cancer from September 2015 to June 2020. All patients underwent total hysterectomy with salpingo-ophorectomy and SLN mapping. RESULTS: A total of 3105 SLNs were mapped and removed, 2809 (90.5%) of these were bilateral and 296 (9.5%) unilateral. The overall detection rate was 93.4% (77.9% bilateral and 15.5% unilateral). The majority of SLNs (80%) and positive SLNs (77.8%) were found at the external iliac and obturator level in both endometrioid and non-endometrioid endometrial cancer. Negative SLNs were more frequent in patients with endometrioid compared with non-endometrioid cancer (91.9% vs 86.1%, p<0.0001). Older patients, a higher body mass index, and non-endometrioid histology were more likely to have 'no mapping' (p<0.0001). Univariate and multivariate analysis showed that higher body mass index and age at surgery were independent predictive factors of empty node packet and fat tissue (p=0.029 and p<0.01, respectively). CONCLUSION: The most frequent sites of SLNs and metastases were located in the pelvic area below the iliac vessel bifurcation. Our findings showed that older age, a higher body mass index, and non-endometrioid histology had a negative impact on mapping.

Nodal Assessment in Endometrial Atypical Hyperplasia.

OBJECTIVE: Atypical endometrial hyperplasia (AH) is the neoplastic precursor more often associated with endometrial cancer (EC). Nowadays, 25-50% of patients subjected to hysterectomy for preoperative AH are diagnosed with EC at the final pathological analysis. Furthermore, there is no consensus on which preoperative AH patients would benefit from sentinel lymph node mapping. This study aimed to evaluate nodal assessment and preoperative cancer risk factors in preoperative AH patients undergoing nodal surgical staging. METHODS: Patients undergoing surgical treatment for AH were retrospectively included in the analysis. Patients were divided into two groups (AH and EC groups) based on the final surgical pathology. The ESGO/ESTRO/ESP risk classification was used for EC cases. DESIGN: This was a retrospective study. RESULTS: Of the 207 AH patients treated, 152 cases met the inclusion criteria. Among preoperative AH patients with final EC diagnosis, 39 patients were in the low-risk group (25.7%), 8 in the intermediate-risk group (5.3%), 4 in high-intermediate (2.6%), and 3 patients were allocated in the high-risk group (2.0%). Fifty-four total patients underwent nodal surgical staging. Only one nodal micrometastasis (0.7%) was found at ultrastaging. Multivariate analysis showed abnormal uterine bleeding (AUB) (p = 0.01), hypertension (p < 0.01), and endometrial thickness ≥20 mm (p = 0.02) statistically more represented in patients with EC at final surgical analysis. EC risk was 2.9 (95% CI: 1.29-6.48) in AUB, 2.7 (95% CI: 1.06-6.92) in hypertension, and 3.1 (95% CI: 1.19-7.97) in endometrial thickness ≥20 mm cases. LIMITATIONS: The present study has limitations inherent in its retrospective nature. CONCLUSION: The overall risk of nodal metastases in preoperative AH patients was low. Conversely, 9.9% of the preoperative AH patients belonged to the intermediate or high-risk group for EC at the final histological examination. Preoperative cancer risk factors would identify AH patients for whom nodal staging could be suggested.

Update of Robotic Surgery in Benign Gynecological Pathology: Systematic Review.

Background and Objectives: Since the Food and Drug Administration's (FDA) approval in 2005, the application of robotic surgery (RS) in gynecology has been adopted all over the world. This study aimed to provide an update on RS in benign gynecological pathology by reporting the scientific recommendations and high-value scientific literature available to date. Materials and Methods: A systematic review of the literature was performed. Prospective randomized clinical trials (RCT) and large retrospective trials were included in the present review. Results: Twenty-two studies were considered eligible for the review: eight studies regarding robotic myomectomy, five studies on robotic hysterectomy, five studies about RS in endometriosis treatment, and four studies on robotic pelvic organ prolapse (POP) treatment. Overall, 12 RCT and 10 retrospective studies were included in the analysis. In total 269,728 patients were enrolled, 1721 in the myomectomy group, 265,100 in the hysterectomy group, 1527 in the endometriosis surgical treatment group, and 1380 patients received treatment for POP. Conclusions: Currently, a minimally invasive approach is suggested in benign gynecological pathologies. According to the available evidence, RS has comparable clinical outcomes compared to laparoscopy (LPS). RS allowed a growing number of patients to gain access to MIS and benefit from a minimally invasive treatment, due to a flattened learning curve and enhanced dexterity and visualization.

Is Adnexectomy Mandatory at the Time of Hysterectomy for Uterine Sarcomas? A Systematic Review and Meta-Analysis.

Background and Objectives: Uterine sarcomas represents only 3% of all the female genital tract ones. The tumoral stage is the most significant prognostic factor. The role of the bilateral salpingo-oophorectomy (BSO) in the surgical management of FIGO stage IA and IB appears still controversial. This review aims to investigate the impact of bilateral adnexectomy in the treatment of uterine sarcoma. Methods: Following the recommendations in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, we systematically searched the PubMed, Scopus, Cochrane, Medline, and Medscape databases in February 2022. We applied no language or geographical restrictions, but we considered only English studies. We included the studies containing data about Recurrence Rate (RR), Disease-free Survival (DFS), and Overall Survival (OS). We used comparative studies for meta-analysis. Results: Seventeen studies fulfilled the inclusion criteria; 2 retrospective observational studies, and 15 retrospective comparative studies, And 14 out of the 15 comparative studies were enrolled in meta-analysis. A total of 3743 patients were analyzed concerning the use of adnexectomy with hysterectomy in patients with uterine sarcoma and compared with those who did not. Meta-analysis highlighted a non-significant worsening of the OS in the BSO group compared to the OP group and showed that adnexectomy does not improve the DFS (BSO OR 1.23 (95% CI 0.81-1.85) p = 0.34; I2 = 24% p = 0.22). Conclusions: Most studies selected for our review showed that adnexectomy does not significantly affect the RR, OS, and PFS in treating FIGO stage I uterine sarcomas. Therefore, even if there is a unanimous consensus about bilateral adnexectomy in menopausal patients, preservation of ovarian tissue may be considered in premenopausal women. Nonetheless, there are not enough cases in the literature to recommend this procedure.

Urologic Complication after Laparoscopic Hysterectomy in Gynecology Oncology: A Single-Center Analysis and Narrative Review of the Literature.

Background and Objectives: Minimally invasive surgery (MIS) has recently increased its application in the treatment of gynecological malignancies. Despite technological and surgical advances, urologic complications (UC) are still the main concern in gynecology surgery. Current literature reports a wide range of urinary tract injuries, and consistent scientific evidence is still lacking or dated. This study aims to report a large single-center experience of urinary complications during laparoscopic hysterectomy for gynecologic oncologic disease. Materials and Methods: All patients who underwent laparoscopic hysterectomy for gynecologic malignancy at the Department of Medicine and Surgery of the University Hospital of Parma from 2017 to 2021 were retrospectively included. Women with endometrial cancer, cervical cancer, ovarian cancer, uterine sarcoma, or borderline ovarian tumors were included. Patients undergoing robotic surgery with incomplete anatomopathological data or patients lost during follow-up were excluded from the analysis. Intraoperative and postoperative UC were analyzed and ranked according to the Clavien-Dindo classification. Results: Two hundred-sixty patients were included in the study: 180 endometrial cancer, 18 cervical cancer, nine ovarian cancer, two uterine sarcomas, and 60 borderline ovarian tumors. Nine (3.5%) UCs were reported (five intraoperative and four postoperative complications). No anamnestic variables showed a statistical correlation with the surgical complication in the univariable analyses. C1 radical hysterectomy, a higher FIGO stage, and postoperative adjuvant treatment (p-value = 0.001, p-value = 0.046, and p-value = 0.046, respectively) were independent risk factors associated with the occurrence of UC. Conclusions: The urological complication rates in patients with oncological disease are relatively rare events in the expert hands of dedicated surgeons. Radical hysterectomy, FIGO stage, and adjuvant treatment are independent factors associated with urinary complications.

Discrimination of Different Breast Cell Lines on Glass Substrate by Means of Fourier Transform Infrared Spectroscopy.

Fourier transform infrared (FTIR) micro-spectroscopy has been attracting the interest of many cytologists and histopathologists for several years. This is related to the possibility of FTIR translation in the clinical diagnostic field. In fact, FTIR spectra are able to detect changes in biochemical cellular components occurring when the cells pass to a pathological state. Recently, this interest has increased because it has been shown that FTIR spectra carried out just in the high wavenumber spectral range (2500-4000 cm-1), where information mainly relating to lipids and proteins can be obtained, are able to discriminate cell lines related to different tissues. This possibility allows to perform IR absorption measurements of cellular samples deposited onto microscopy glass slides (widely used in the medical environment) which are transparent to IR radiation only for wavenumber values larger than 2000 cm-1. For these reasons, we show that FTIR spectra in the 2800-3000 cm-1 spectral range can discriminate three different cell lines from breast tissue: a non-malignant cell line (MCF10A), a non-metastatic adenocarcinoma cell line (MCF7) and a metastatic adenocarcinoma cell line (MDA). All the cells were grown onto glass slides. The spectra were discriminated by means of a principal component analysis, according to the PC1 component, whose values have the opposite sign in the pairwise score plots. This result supports the wide studies that are being carried out to promote the translation of the FTIR technique in medical practice, as a complementary diagnostic tool.

Confounding factors of transvaginal ultrasound accuracy in endometrial cancer.

Endometrial cancer is the most frequently diagnosed gynecological tumour. Transvaginal ultrasound has a leading role in the preoperative evaluation of endometrial cancer patients. The study aimed to identify factors that can worsen the diagnostic accuracy of transvaginal ultrasound in endometrial cancer patients. We retrospectively analysed 290 patients with histological diagnosis of endometrial adenocarcinoma. Two-dimensional (2D) gray-scale ultrasound and power Doppler imaging were performed. Age, menopause status, obesity, parity, Figo stage and benign uterine disorders were evaluated as possible factors worsening the diagnostic accuracy of the ultrasonography. FIGO stage IB was the main significant confounding factor in the univariate analysis (p = .004). Furthermore, 2D transvaginal ultrasound showed worse diagnostic accuracy in endometrial cancer patients with concomitant benign uterine pathologies.Impact statementWhat is already known on this subject? Many studies have analysed the reliability and diagnostic accuracy of transvaginal ultrasound in predicting myometrial invasion, but few studies have underlined the importance of confounding factors. Shin et al. (2011) showed that diffuse fibromatosis is a quality ultrasound confounding factor. Furthermore, Fischerova et al. (2014) showed that body mass index (BMI) did not influence the diagnostic accuracy of ultrasound assessment.What do the results of this study add? FIGO stage IB is the main factor worsening the diagnostic accuracy of transvaginal ultrasound in endometrial cancer patients (p = .004). Among the 82 patients with histologically proven FIGO stage IB, 27 (32.9%) had a wrong ultrasound prediction of myometrial infiltration. Twenty-one (36.2%) patients in whom there was no agreement between ultrasound prediction of myometrial infiltration and pathological analysis had fibromatosis and/or adenomyosis (p = 0.04).What are the implications of these findings for clinical practice and/or further research? Two-dimensional ultrasound represents a useful tool in the correct pre-operative setting of patients with endometrial cancer. In FIGO stages IB endometrial cancer patients and in conjunction with benign uterine pathologies, 2D transvaginal ultrasound has less diagnostic accuracy. In these cases, MRI still plays a leading role.

How to Select Early-Stage Cervical Cancer Patients Still Suitable for Laparoscopic Radical Hysterectomy: a Propensity-Matched Study.

BACKGROUND: Recently, it was reported that minimally invasive surgery (MIS) has a negative impact on early-stage cervical cancer (ECC) patient survival. At the same time, advantages of MIS regarding quality of life and low rate of intra- and postoperative complications are well known. Therefore, it is essential to select patients who may benefit from MIS without worsening their oncologic outcomes. The aim of this study is to investigate which pathological factors could guide surgeons' choice about the best approach in ECC. PATIENTS AND METHODS: Patients with 2009 FIGO stage from IA1 with lymphovascular space invasion (LVSI) to IB1/IIA1 treated by open or laparoscopic surgery were judged eligible for the study. Disease-free survivals (DFS) of both approaches were tested in subgroups, defined according to histology, tumor size, grading, LVSI, parametrial involvement, and nodal status. RESULTS: A total of 423 patients were enrolled (217 in the open and 206 in the laparoscopic group). No difference between open surgery and laparoscopy was found among subgroups defined according to histology, grading, LVSI, parametrial involvement, or nodal status. Among patients with tumor > 20 mm, laparoscopy showed a significantly higher relapse risk [hazard ratio (HR): 2.103, p = 0.030]. Among patients with tumor < 20 mm, laparoscopy showed DFS superimposable to open surgery (HR: 0.560, p = 0.128). CONCLUSIONS: Tumor size of 20 mm appeared as the only independent discrimination criterion in patients whose prognosis is affected by surgical approaches.

Laparoscopic sentinel node mapping with intracervical indocyanine green injection for endometrial cancer: the SENTIFAIL study - a multicentric analysis of predictors of failed mapping.

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 pre-operative 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], non-endometrioid 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, non-endometrioid histology, and intra-operative finding of enlarged lymph nodes were identified as independent risk factors for unsuccessful mapping in patients undergoing laparoscopic SLN mapping.

Novel preoperative predictive score to evaluate lymphovascular space involvement in endometrial cancer: an aid to the sentinel lymph node algorithm.

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.
