BackgroundPositron emission tomography/computed tomography (PET/CT) fails to detect approximately 25% of aortic lymph node metastasis in patients with PET/CT stage IIIC1 cervical cancer. Surgical staging could lead to treatment modification and to improved para-aortic and distant control.Primary Objective(s)To demonstrate if chemoradiation with tailored external beam radiation field based on surgical staging and pathologic examination of the para-aortic lymph node is associated with improved 3-year disease-free survival compared with patients staged with PET/CT staging only.Study HypothesisSurgical staging followed by tailored chemoradiation will improve disease-free survival while avoiding unnecessary prophylactic extended-field chemoradiation in patients with International Federation of Gynecology and Obstetrics (FIGO) stage IIIC1 cervical cancer.Trial DesignThis is an international multicenter, randomized, phase III study. Eligible patients will be randomized 1:1 between PET/CT staging followed by chemoradiation (control arm), or surgical staging followed by tailored chemo-radiation (experimental arm). Randomization will be stratified by tumor stage according to TNM classification, center, and adjuvant treatment.Major Inclusion/Exclusion CriteriaMain inclusion criteria are histologically proven PET/CT FIGO stage IIIC1 cervical cancer. Main exclusion criteria include unequivocal positive common iliac or para-aortic lymph node at pre-therapeutic imaging PET/CT.Primary Endpoint(s)The primary endpoint is disease-free survival defined as the time from randomization until first relapse (local, regional, or distant), or death from any cause.Sample Size510 eligible patientsEstimated Dates for Completing Accrual and Presenting ResultsThe estimated date for completing accrual will be Q2 2027. The estimated date for presenting results will be Q4 2030.Trial Registration NumberNCT05581121.

The transcription factor CCAAT/enhancer binding protein-α (C/EBPα) is involved in the control of cell differentiation and proliferation, and has been suggested to act as a tumor suppressor in several cancers. By using microarray analysis, we have previously shown that hypoxia and estrogen down-regulate C/EBPα mRNA in T-47D breast cancer cells. Here, we have examined the mechanism by which the down-regulation by hypoxia takes place. Using the specific RNA polymerase II inhibitor 5,6-dichlorobenzimidazole-1-β-d-ribofuranoside, the mRNA stability was analyzed under normoxia or hypoxia by quantitative reverse transcription-PCR. Hypoxia reduced the half-life of C/EBPα mRNA by ∼30%. C/EBPα gene promoter studies indicated that hypoxia also repressed the transcription of the gene and identified a hypoxia-responsive element (−522; −527 bp), which binds to hypoxia-inducible factor (HIF)-1α, as essential for down-regulation of C/EBPα transcription in hypoxia. Immunocytochemical analysis showed that C/EBPα was localized in the nucleus at 21% O2, but was mostly cytoplasmic under 1% O2. Knockdown of HIF-1α by RNAi restored C/EBPα to normal levels under hypoxic conditions. Immunohistochemical studies of 10 tumor samples did not show any colocalization of C/EBPα and glucose transporter 1 (used as a marker for hypoxia). Taken together, these results show that hypoxia down-regulates C/EBPα expression in breast cancer cells by several mechanisms, including transcriptional and posttranscriptional effects. The down-regulation of C/EBPα in hypoxia is mediated by HIF-1. [Cancer Res 2008;68(7):2158–65]

In order to define the clinical significance of low-volume metastasis, a comprehensive meta-analysis of published data and individual data obtained from articles mentioning micrometastases (MIC) and isolated tumor cells (ITC) in cervical cancer was performed, with a follow up of at least 3 years.We performed a systematic literature review and meta-analysis, following Cochrane's review methods guide and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The primary outcome was the disease-free survival (DFS), and the secondary outcome was the overall survival (OS). The hazard ratio (HR) was taken as the measure of the association between the low-volume metastases (MIC+ITC and MIC alone) and DFS or OS; it quantified the hazard of an event in the MIC (+/- ITC) group compared to the hazard in node-negative (N0) patients. A random-effect meta-analysis model using the inverse variance method was selected for pooling. Forest plots were used to display the HRs and risk differences within individual trials and overall.Eleven articles were finally retained for the meta-analysis. In the analysis of DFS in patients with low-volume metastasis (MIC + ITC), the HR was increased to 2.60 (1.55-4.34) in the case of low-volume metastasis vs. N0. The presence of MICs had a negative prognostic impact, with an HR of 4.10 (2.71-6.20) compared to N0. Moreover, this impact was worse than that of MIC pooled with ITCs. Concerning OS, the meta-analysis shows an HR of 5.65 (2.81-11.39) in the case of low-volume metastases vs. N0. The presence of MICs alone had a negative effect, with an HR of 6.94 (2.56-18.81).In conclusion, the presence of MIC seems to be associated with a negative impact on both the DFS and OS and should be treated as MAC.

International audience; Objectives: To compare oncologic outcomes of patients with early-stage cervical cancer and negative nodes who underwent sentinel lymph node biopsy alone (SLNB) versus pelvic lymphadenectomy (PL).Methods: An ancillary analysis of two prospective multicentric trials on SLN biopsy for cervical cancer (SENTICOL I and II) was conducted. Only patients with early-stage cervical cancer (IA to IIA FIGO stage), bilateral detection of SLN, negative SLN after ultrastaging and negative non-SLN after final pathologic examination were included. Risk-factors of recurrence and disease-specific mortality were determined by Cox proportional hazard models.Results: Between January 2005 and July 2012, 259 node-negative patients were analyzed: 87 in the SLNB group and 172 in the PL group. The median follow-up was 47 months [4-127]. During the follow-up, 21 patients (8.1%) experienced recurrences, including 4 nodal recurrences (1.9%), and 9 patients (3.5%) died of cervical cancer. Disease-free survival (DFS) and disease-specific survival (DSS) were similar between SLNB and PL groups, 85.1% vs. 80.4%, p = 0.24 and 90.8% vs. 97.2%, p = 0.22 respectively. By Cox multivariate analysis, SLNB compared to PL was not associated with DFS (HR = 1.78, 95%CI = [0.71-4.46], p = 0.22) neither with DSS (HR = 3.02, 95%CI = [0.69-13.18], p = 0.14). Only pathologic risk level according to the Sedlis criteria was an independent predictor of DFS and DSS.Conclusions: Omitting full pelvic lymphadenectomy for patients with bilateral negative SLN does not seem to be associated with an increased risk of recurrence in this series. Survival non-inferiority needs to be confirmed by prospective trials.

ImportanceAlthough Africa has the highest burden of cervical cancer in the world, educational resources to achieve the 90-70-90 targets set by the World Health Organization in its strategy to eliminate cervical cancer are lacking in the region.ObjectivesTo adapt, implement, and evaluate the Project Extension for Community Health Care Outcomes (ECHO), an innovative learning tool, to build capacity of clinicians to better incorporate new evidence-based guidelines into cervical cancer control policies and clinical practices.Design, Setting, and ParticipantsThis cross-sectional study assessed knowledge and practices of clinicians and support staff regarding cervical cancer prevention and control and compared them among respondents who had attended Project ECHO sessions (prior ECHO attendees) with those who had not but were planning on attending in the near future (newcomers) as part of the Cameroon Cervical Cancer Prevention Project ECHO. Satisfaction of prior ECHO attendees was also evaluated. Data were analyzed from January to March 2022.Main Outcomes and MeasuresMain outcomes were practices and knowledge regarding cervical cancer education and prevention and preinvasive management procedures compared among prior ECHO attendees and newcomers.ResultsOf the 75 participants (mean [SD] age, 36.4 [10.0] years; 65.7% [95% CI, 54.3%-77.1%] women) enrolled in this study, 41 (54.7%; 95% CI, 43.1%-66.2%) were prior ECHO attendees, and most were clinicians (55 respondents [78.6%; 95% CI, 68.7%-88.4%]). Overall, 50% (95% CI, 37.8%-62.2%) of respondents reported performing cervical cancer screening with visual inspection of the cervix after application of acetic acid (VIA) and/or visual inspection of the cervix after application of Lugol’s iodine (VILI), 46.3% (95% CI, 34.0%-58.5%) of respondents reported performing human papillomavirus (HPV) testing, and 30.3% (95% CI, 18.9%-41.7%) of respondents reported performing cervical cytological examination in their practices, Approximately one-fourth of respondents reported performing cryotherapy (25.4% [95% CI, 14.7%-36.1%]), thermal ablation (27.3% [95% CI, 16.2%-38.3%]) or loop electrosurgical excisional procedure (LEEP, 25.0% [95% CI, 14.4%-35.6%]) for treatment of preinvasive disease. The clinical use of many of these screening and treatment tools was significantly higher among prior ECHO attendees compared with newcomers (VIA/VILI: 63.2% [95% CI, 47.4%-78.9%] vs 33.3% [95% CI, 16.0%-50.6%]; P = .03; cryotherapy: 40.5% [95% CI, 24.3%-56.8%] vs 6.7% [95% CI, 0.0%-15.8%]; P = .002; thermal ablation: 43.2% [95% CI, 26.9%-59.6%] vs 6.9% [95% CI, 0.0%-16.4%]; P = .002). Knowledge about cervical cancer education, prevention, and management procedures was satisfactory in 36.1% (95% CI, 23.7%-48.5%) of respondents; this proportion was significantly higher among prior ECHO attendees (53.8% [95% CI, 37.7%-69.9%]) compared with newcomers (4.5% [95% CI, 0.0%-13.5%]; P Conclusions and RelevanceThese findings suggest that the Project ECHO e-learning and telementoring program was associated with improved skills for clinicians and support staff and enhanced quality of care for patients. In the COVID-19 era and beyond, reinforced efforts to strengthen cervical cancer knowledge and best practices through distance learning and collaboration are needed.

Resumen El cancer de vulva, que afecta en la mayoria de los casos a mujeres de edad avanzada, es un cancer infrecuente, pero grave, debido a las caracteristicas de las pacientes en las que aparece. La cirugia es la piedra angular de su tratamiento y ha experimentado una reduccion de su morbilidad perioperatoria local y ganglionar con el desarrollo de la tecnica del ganglio centinela en los ultimos anos. El estatus ganglionar es un factor pronostico principal. El tratamiento quirurgico depende del estadio TNM (tumor, ganglios [node], metastasis). Para los estadios mayores a T1a, consiste en una vulvectomia radical, parcial o total, con el objetivo de obtener unos margenes de al menos 1 cm asociados a una evaluacion ganglionar sistematica. Por ultimo, los progresos de la radioterapia asociada a las tecnicas de quimiosensibilizacion permiten ofrecer alternativas terapeuticas aceptables a los estadios TNM mas avanzados.

Resumen El cancer del cuello uterino se debe a la infeccion cronica por el virus del papiloma humano (VPH), que se transmite por via sexual, y su tratamiento quirurgico se basa en la colpohisterectomia ampliada para los estadios precoces.

Aqui se describe la tecnica quirurgica de colpohisterectomia ampliada por laparoscopia que se utiliza en el centro de los autores de este articulo. A continuacion, se describen las principales complicaciones y una revision de la literatura sobre los resultados de estas tecnicas minimamente invasivas.

Introduction Pelvic lymph node dissection has been the standard of care for patients with early cervical cancer. Sentinel node (SN) mapping is safe and feasible and may increase the detection of metastatic disease, but benefits of omitting pelvic lymph node dissection in terms of decreased morbidity have not been demonstrated. Materials and methods In an open-label study, patients with early cervical carcinoma (FIGO 2009 stage IA2 to IIA1) were randomly assigned to SN resection alone (SN arm) or SN and pelvic lymph node dissection (SN + PLND arm). SN resection was followed by radical surgery of the tumour (radical hysterectomy or radical trachelectomy). The primary end-point was morbidity related to the lymph node dissection; 3-year recurrence-free survival was a secondary end-point. Results A total of 206 patients were eligible and randomly assigned to the SN arm (105 patients) or SN + PLND arm (101 patients). Most patients had stage IB1 lesion (87.4%). No false-negative case was observed in SN + PLND arm. Lymphatic morbidity was significantly lower in the SN arm (31.4%) than in the SN + PLND arm (51.5%; p = 0.0046), as was the rate of postoperative neurological symptoms (7.8% vs. 20.6%, p = 0.01, respectively). However, there was no significant difference in the proportion of patients with significant lymphoedema between the two groups. During the 6-month postoperative period, the difference in morbidity decreased over time. The 3-year recurrence-free survival was not significantly different (92.0% in SN arm and 94.4% in SN + PLND arm). Conclusion SN resection alone is associated with early decreased lymphatic morbidity when compared with SN + PLND in early cervical cancer.

Surgical studies have specific issues, such as quality assurance on procedures, standardization of techniques, surgeon effect, timing of randomization, blinding respect or choice of the reference arm. All these difficulties conducted to criticism many trials, and lack of results implementation. Indeed, adherence to methodological guidelines is often poor. Twelve recommendations were recently issued by the JAMA surgery revue for good practice in surgical studies to improve the quality of surgical trials in general and surgical oncology. We detail here the main issues of surgical trials in gynaecological oncology surgery, as well as possibilities of improvement for future studies.

Background The sentinel lymph node (SLN) biopsy may be an alternative to systematic lymphadenectomy in early cervical cancer. The SLN biopsy is less morbid and has been shown to have high sensitivity for metastasis detection. However, the sensitivity of the SLN technique might be overevaluated because SLNs are examined with ultra-staging, and non-sentinel nodes usually are examined only with routine techniques. This study aimed to validate the negative predictive value (NPV) of the SLN technique by the ultra-staging of SLNs and non-sentinel nodes (NSLNs). Methods The SENTICOL 1 study data published in 2011 were used. All nodes (i.e., SLNs and NSLNs) were secondarily subjected to ultra-staging. The ultra-staging consisted of sectioning every 200 µm, in addition to immunohistochemistry. Moreover, the positive slides and 10% of the negative slides were reviewed. Results The study enrolled 139 patients, and SLNs were detected in 136 (97.8%) of these patiets. Bilateral SLNs were detected in 104 (76.5%) of the 136 patients. A total of 2056 NSLNs were identified (median, 13 NSLNs per patient; range 1–54). Of the 136 patients with SLNs, 23 were shown to have positive SLNs after serial sectioning and immunohistochemical staining. The NSLNs were metastatic in six patients. In the case of bilateral SLN detection, the NPV was 100%, with no false-negatives (FNs). Conclusions The pelvic SLN technique is safe and trustworthy for determining the nodal status of patients with early-stage cervical cancer. In the case of optimal mapping with bilateral detection, the NPV was found to be 100%.

Introduction Detection of sentinel lymph node in early breast cancer is commonly based on the combination of patent blue dye and a radioisotope 99m Technetium. Each of these two tracers has advantages and disadvantages leading to the development of the use of indocyanine green. Methods We conducted a prospective clinical trial to compare the detection rate of indocyanine green with 99mTe. Each patient undergoing a sentinel lymph node biopsy for an early breast cancer received both indocyanine green and radioisotopes. The trial was registered: FLUOBREAST EudraCT N 2015-000698-11, ClinicalTrials.gov: NCT02875626. Results Among a total of 88 patients, 77 were assessable for a total of 205 nodes. Detection rates were 93% for the isotope and 96% for the indocyanine green. The combined detection rate was 99%. The overall concordance rate per patient was 91%. The median number of excised sentinel nodes was 2.3 for each tracer and 2.7 for the combined method (P = .21). All the macrometastatic nodes were detected by both indocyanine green and radioisotopes. The median time between incision of the axilla and removal of the last node was 14 minutes. There was neither allergy nor radio-sensitization linked with the use of indocyanine green. Conclusions Indocyanine green delivers a high detection rate and sensitivity for the sentinel lymph node biopsy in early breast cancer, with short operative time and a normal number of excised sentinel lymph nodes. Allergy is extremely rare and there is no toxicity. Indocyanine green could be an alternative to radioisotopes to provide an accurate staging of the axilla. Its routine use should be approved.

Objectives We aimed to assess the diagnostic value of frozen-section pathologic examination (FSE) of sentinel lymph nodes (SLN) in patients with early-stage cervical cancer. Methods Two French prospective multicentric database on SLN biopsy for cervical cancer (SENTICOL I and II) were analysed. Patients with IA to IIA1 2018 FIGO stage, who underwent SLN biopsy with both FSE and ultrastaging examination were included. Results and discussion Between 2005 and 2012, 313 patients from 25 centers fulfilled the inclusion criteria. Metastatic involvement of SLN was diagnosed in 52 patients (16.6%). Macrometastases, micrometastases and isolated tumor cells (ITCs) were found in 27, 12 and 13 patients respectively. Among the 928 SLNs analysed, FSE identified 23 SLNs with macrometastases in 20 patients and 5 SLNs with micrometastases in 2 patients whereas no ITCs were identified. Ultrastaging of negative SLNs by FSE found macrometastases, micrometastases and ITCs in additional 7, 11 and 17 SLNs. Ultrastaging increased significantly the rate of patients with positive SLN from 7% to 16.6% (p The sensitivity and the negative predictive value of FSE were 42.3% and 89.7% respectively or 56.4% and 94.1% if ITCs were excluded. False-negative cases were more frequent with tumor size ≥ 20 mm (OR = 4.46, 95%IC = [1.45–13.66], p = 0.01) and preoperative brachytherapy (OR = 4.47, 95%IC = [1.37–14.63], p = 0.01) and less frequent with patients included in higher volume center (>5 patients/year) (OR = 0.09, 95%IC = [0.02–0.51], p = 0.01). Conclusions FSE of SLN had a low sensitivity for detecting micrometastases and ITCs and a high negative predictive value for SLN status. Clinical impact of false-negative cases has to be assessed by further studies.

Aim The surgical treatment of endometrial cancer (EC) can be more complicated in obese patients. Robotic surgery could simplify the surgical approach in these patients. The aim of our study was to compare the outcomes of robotic surgery in obese (body mass index ≥30 kg/m2 ) and nonobese patients. Methods We performed a retrospective study on patients with EC benefitting from a robotic approach in our institution. The primary outcome was the 5-year overall survival (OS). We also assessed the 5-year recurrence-free survival (RFS), type of surgery, laparotomy conversion rate, adjuvant treatment and postoperative morbidity. Results We analyzed 175 consecutive patients with EC who underwent robotic surgery, 42 patients with obesity and 133 patients without. The median follow-up length was 37 months [1-120]. The OS rate was 97% in the whole population and the RFS was 74%. Obesity did not impact prognosis. Laparotomy conversion rate was low in both groups (5% in patients with obesity vs 3%, P = 0.619). There were no significant differences in terms of postoperative complications (5 vs 9%, P = 0.738). There were significantly less pelvic lymphadenectomies in patients with obesity (5 vs 12%, P = 0.005). In the subgroup of patients with high-risk EC, rate of lymphadenectomy and of adjuvant treatments did not differ between patients with or without obesity. Conclusion Obese patients with EC can be safely treated with a robotic approach, with a low complication rate and similar oncological outcomes compared to nonobese patients.

IntroductionRadical hysterectomy is the gold standard in the management of early-stage cervical cancer. Parametrectomy aims to remove occult disease but is associated with significant surgical morbidity. Avoiding unnecessary parametrectomy in a subset of patients at low risk of parametrial involvement may decrease the incidence of such morbidity. The purpose of this study was to identify patients at low risk of parametrial involvement in early-stage cervical cancer potentially eligible for less radical surgery based on pre-operative criteria and sentinel lymph node (SLN) status.MethodsWe performed an ancillary analysis of data from two prospective trials on sentinel node biopsy for cervical cancer (SENTICOL I and II). Patients with International Federation of Gynecology and Obstetrics (FIGO) IA–IIA cervical cancer who underwent primary radical surgery and bilateral SLN mapping were identified between 2005 and 2012 from 25 French oncologic centers. Patients who underwent pre-operative brachytherapy or did not undergo radical surgery (simple trachelectomy, simple hysterectomy, or lymph node staging only) were excluded.ResultsOf 174 patients who fullfiled the inclusion criteria, 9 patients (5.2%) had parametrial involvement and 24 patients (13.8%) had positive SLN. Most patients had 2018 FIGO stage IB1 disease (86.1%) and squamous cell carcinomas (68.9%). Parametrial involvement was significantly associated with tumor size ≥20 mm on pelvic magnetic resonance imaging (MRI) (adjusted odds ratio (ORa) 9.30, 95% CI 1.71 to 50.57, p=0.01) and micrometastic or macrometastatic SLN (ORa 8.98, 95% CI 1.59 to 50.84, p=0.01). Of 114 patients with tumors ConclusionsLess radical surgery may be an option for patients with bilateral negative SLN after ultrastaging and tumors

Resume Le statut ganglionnaire est le facteur pronostique le plus important chez les patientes atteintes d’un cancer du col uterin aux stades precoces. Le prelevement du ganglion sentinelle est une technique precise permettant d’evaluer le risque d’envahissement ganglionnaire en substitution aux curages pelviens systematiques. Une chirurgie ganglionnaire moins agressive permet de diminuer la morbidite induite par les curages pelviens, en particulier le risque de lymphœdeme des membres inferieurs. L’analyse histologique du ganglion sentinelle permet une ultrastadification qui identifie de faibles volumes tumoraux (cellules tumorales isolees et micrometastases). Sur le plan anatomique, la technique du ganglion sentinelle fournit des informations plus precises sur le drainage lymphatique des tumeurs du col en identifiant des nœuds lymphatiques en dehors des zones de curages classiques. La selection d’une population de patientes a faible risque d’atteinte ganglionnaire, une courbe minimale d’apprentissage et des regles simples garantissent un faible taux de faux negatifs. Plusieurs etudes ont montre que la technique du ganglion sentinelle est faisable, avec d’excellents taux de detection et de sensibilite. La technique combinee avec le technetium-99 et le bleu patente est largement utilisee mais la methode par fluorescence recemment introduite a montre de meilleurs taux de detection des ganglions sentinelles. Bien que les principales recommandations internationales recentes incitent a un prelevement du ganglion sentinelle en complement du curage pelvien, le prelevement exclusif du ganglion sentinelle n’est pas encore la reference, du au manque de donnees prospectives sur la survie sans recidive. Certains points sont encore discutes, tels que la valeur de l’examen extemporane du ganglion sentinelle et l’impact a long terme des micrometastases. L’essai prospectif randomise SENTICOL III devrait repondre a ces problematiques.

Resumen El tratamiento del cancer de endometrio esta bien codificado, en particular con las recomendaciones de la Societe Francaise d’Onco-Gynecologie-College National des Gynecologues et Obstetriciens Francais (SFOG-CNGOF) publicadas en 2017. Se recomienda la cirugia minimamente invasiva, especialmente para los estadios 1 y, si se cumplen algunas condiciones, para los estadios 2. Se debe comprobar antes de la intervencion la factibilidad tecnica, con una evaluacion preterapeutica que conste de una resonancia magnetica (RM) y de una exploracion fisica en la consulta y, despues, bajo anestesia general antes de comenzar la intervencion. Los autores de este articulo detallan las diferentes etapas de la histerectomia por laparoscopia en el tratamiento del cancer de endometrio, los procedimientos que se pueden asociar y el postoperatorio previsible.

Objectives Description of fertility and prognosis of patients with borderline ovarian tumor (BOT) treated by fertility-sparing surgery through a longitudinal study from the French national cancer network. Methods All consecutive patients diagnosed with BOT from the French National Network dedicated to Ovarian Malignant Rare Tumors from 2010 and 2017 were selected. In 2018, an update was made by sending a questionnaire regarding recurrence and fertility to patients aged under 43 years at diagnosis and treated conservatively. We compared the characteristics of the patients with/without recurrence and with/without live birth. Results Fifty-two patients aged 18 to 42 years presented a desire of pregnancy. Thirty patients (58%) presented a FIGO IA tumor, and 20 patients were treated by bilateral cystectomies (38%). We observed at least one live birth for 33 patients (63%) and local recurrences in 20 patients (38%). Both recurrence and live birth in 17 patients (33%) were reported, with recurrence occurring before pregnancy, after a second fertility-sparing treatment, in half of the cases. No factors associated with recurrence or live birth in this study were identified. Moreover, in this population, both recurrence and live birth were independent of age, with a linear risk along time. Disease-free survival was worse for patients treated with bilateral cystectomy (n = 20, 38%), with no difference in terms of fertility. Conclusion Two third of the patients experienced life birth after conservation surgery. We did not highlight an age/time from surgery for which the risk of recurrence outweighs the chance of pregnancy and to radicalize surgery. Moreover, almost a quarter of the live birth occurred after recurrence, with no more further event to date in these patients. The results encourage to consider a second fertility-sparing surgery after local borderline recurrence in the case of pregnancy desire. All these decisions must be discussed in specialized multidisciplinary boards.

Background The objective of this study was to determine clinical, tumoral and surgical factors associated with successful bilateral sentinel lymph node mapping (SBM) in early-stage cervical cancer. Methods We performed an ancillary work on the data of two prospective trials on SLN biopsy for FIGO IA-IIA cervical cancer (SENTICOL I & II). Patients having Sentinel lymph node (SLN) mapping for early-stage cervical cancer were included between 2005 and 2012 from 28 French oncologic centers. SLN was detected by a combined labeling technique (blue and isotopic). Results 405 patients were included for analysis: SLNs were identified on at least one side of the pelvis in 381 patients (94.1%) and bilaterally in 326 patients (80.5%). The mean age was 45.4 years [22–85 years]. Most patients had IB1 pathologic FIGO 2018 stage (81.3%) and squamous cell carcinoma (71%). Surgeries were mainly performed by minimally invasive approach (368 patients – 90.9%). By multivariate analysis, lower SBM rate was significantly associated with Age ≥70 years (ORa = 0.02, 95%CI = [0.001–0.28], p = 0.004), tumor size larger than 20 mm (ORa = 0.46,95%CI = [0.21–0.99], p = 0.048) and Body-mass index higher than 30 kg/m2 (ORa = 0.28, 95%CI = [0.12–0.65], p = 0.003). SBM rate was significantly higher in high skills centers (>5patients/year) (ORa = 8.05, 95%CI = [2.06–31.50], p = 0.003) and in SENTICOL II (2009–2012) compared to SENTICOL I (2005–2007) (ORa = 2.6, 95%CI = [1.23–5.51], p = 0.01). Conclusions In early-stage cervical cancer, bilateral SLN detection rates is lower in patients aged more than 70years, patients with BMI≥30 kg/m2 and larger tumor ≥20 mm whereas stronger experience of SLN biopsy technique improves bilateral SLN detection.

Simple Summary The prognosis of cervical cancer is significantly influenced by lymph node involvement. The lymphatic system is the primary way of metastasis for cervical carcinoma, and lymph-vascular space invasion (LVSI) is considered the most important risk factor for pelvic lymph node metastasis (PLNM). Previous studies have not clarified the correlation between lymphangiogenesis and an increased risk of metastasis and tumor recurrence. The evaluation and identification of several markers of lymphangiogenesis may identify patients with high risk of PLNM. Our findings suggest that the lymphatic spread does not required the proliferation of new lymphatic endothelial cells. These results emphasize the importance of pre-existing peritumoral lymphatic vessels in the metastatic process in early cervical cancer. Abstract Background: In patients with cervical cancer, the presence of tumoral lymph-vascular space invasion (LVSI) is the main risk factor for pelvic lymph node metastasis (PLNM). The objective of this study was to evaluate the presence of several markers of lymphangiogenesis in early-stage cervical cancer and their correlation with PLNM and tumoral recurrence. Materials and Methods: Seventy-five patients with early-stage cervical carcinoma underwent sentinel lymph node (SLN) sampling in association with complete pelvic lymph node dissection. Primary tumors were stained with the following markers: Ki67, D2-40, CD31 and VEGF-C. A 3-year follow-up was performed to evaluate the disease-free survival. Results: Overall, 14 patients (18.6%) had PLNM. Positive LVSI was seen in 29 patients (38.6%). There was a significant correlation between LVSI evidenced by H/E staining and PLNM (p < 0.001). There was no correlation between high Ki67, CD31, D2-40, and VEGF-C staining with PLNM or tumor recurrence. Conclusions: Our data support that lymphatic spread does not require the proliferation of new lymphatic endothelial cells in early-stage cervical cancer. These results emphasize the importance of pre-existing peritumoral lymphatic vessels in the metastatic process in early cervical cancer. None of the markers of lymphangiogenesis and proliferation assessed in this study were predictive of PLNM or recurrence.
