Abstract
OBJECTIVE This study sought to explore the efficiency of para-aortic and pelvic lymphadenectomy in the treatment of locally advanced cervical cancer (LACC) with pelvic lymph node (PLN) metastasis. METHODS A total of 171 LACC patients with imaging-confirmed pelvic lymph node metastasis were included in this study. These patients were divided into two groups: the surgical staging group, comprising 58 patients who had received para-aortic and pelvic lymphadenectomy (surgical staging) along with concurrent chemoradiation therapy (CCRT), and the imaging staging group, comprising 113 patients who had received only CCRT. The two groups' progression-free survival (PFS), overall survival (OS) and treatment-related complications were compared. RESULTS The surgical staging group started radiotherapy 10.2 days (range 9-12 days) later than the imaging staging group. The overall incidence of lymphatic cysts was 9.30%. In the surgical staging group, para-aortic lymph node metastasis was identified in 34.48% (20/58) of patients, while pathology-negative PLN was observed in 12.07% (7/58). Over a median follow-up period of 52 months, no significant differences in PFS and OS rates were found between the two groups (p > 0.05). Subgroup analysis of patients with lymph node diameters of ≥ 1.5 cm revealed a five-year PFS rate of 75.0% and an OS rate of 80.0% in the surgical staging group, compared to 41.5% and 50.1% in the imaging staging group, respectively, showing statistically significant differences (p = 0.022, HR:0.34 [0.13, 0.90] and p = 0.038, HR: 0.34 [0.12,0.94], respectively for PFS and OS). Additionally, in patients with two or more metastatic lymph nodes, the five-year PFS and OS rates were 69.2% and 73.1% in the surgical staging group, versus 41.0% and 48.4% in the imaging staging group, with these differences also being statistically significant (p = 0.025, HR: 0.41[0.19,0.93] and p = 0.046, HR: 0.42[0.18,0.98], respectively). CONCLUSION Performing surgical staging before CCRT is safe and delivers accurate lymph node details crucial for tailoring radiotherapy. This approach merits further investigation, particularly in women with pelvic lymph nodes measuring 1.5 cm or more in diameter or patients with two or more imaging-positive PLNs.

Predictive value of number of metastatic lymph nodes and lymph node ratio for prognosis of patients with FIGO 2018 stage IIICp cervical cancer: a multi-center retrospective study. BMC Cancer 2024; 24:1005. [PMID: 39138415 PMCID: PMC11320992 DOI: 10.1186/s12885-024-12784-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Accepted: 08/08/2024] [Indexed: 08/15/2024] Open
Abstract
BACKGROUND To identify the cut-off values for the number of metastatic lymph nodes (nMLN) and lymph node ratio (LNR) that can predict outcomes in patients with FIGO 2018 IIICp cervical cancer (CC). METHODS Patients with CC who underwent radical hysterectomy with pelvic lymphadenectomy were identified for a propensity score-matched (PSM) cohort study. A receiver operating characteristic (ROC) curve analysis was performed to determine the critical nMLN and LNR values. Five-year overall survival (OS) and disease-free survival (DFS) rates were compared using Kaplan-Meier and Cox proportional hazard regression analyses. RESULTS This study included 3,135 CC patients with stage FIGO 2018 IIICp from 47 Chinese hospitals between 2004 and 2018. Based on ROC curve analysis, the cut-off values for nMLN and LNR were 3.5 and 0.11, respectively. The final cohort consisted of nMLN ≤ 3 (n = 2,378) and nMLN > 3 (n = 757) groups and LNR ≤ 0.11 (n = 1,748) and LNR > 0.11 (n = 1,387) groups. Significant differences were found in survival between the nMLN ≤ 3 vs the nMLN > 3 (post-PSM, OS: 76.8% vs 67.9%, P = 0.003; hazard ratio [HR]: 1.411, 95% confidence interval [CI]: 1.108-1.798, P = 0.005; DFS: 65.5% vs 55.3%, P < 0.001; HR: 1.428, 95% CI: 1.175-1.735, P < 0.001), and the LNR ≤ 0.11 and LNR > 0.11 (post-PSM, OS: 82.5% vs 76.9%, P = 0.010; HR: 1.407, 95% CI: 1.103-1.794, P = 0.006; DFS: 72.8% vs 65.1%, P = 0.002; HR: 1.347, 95% CI: 1.110-1.633, P = 0.002) groups. CONCLUSIONS This study found that nMLN > 3 and LNR > 0.11 were associated with poor prognosis in CC patients.

Abstract
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.

Zhang Y, Wang C, Zhao Z, Cheng L, Xu S, Xie P, Xie L, Zhang S. Survival outcomes of 2018 FIGO stage IIIC versus stages IIIA and IIIB in cervical cancer: A systematic review with meta-analysis. Int J Gynaecol Obstet 2024; 165:959-968. [PMID: 37950594 DOI: 10.1002/ijgo.15218] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Revised: 08/02/2023] [Accepted: 10/17/2023] [Indexed: 11/12/2023]
Abstract
OBJECTIVE To assess the difference in survival outcomes between stage IIIC and stages IIIA and IIIB in the 2018 FIGO cervical cancer staging system. METHODS The PubMed, EMBASE, MEDLINE and Web of Science were searched for articles published from November 1, 2018 to January 31, 2023. Articles published in English were considered. The included studies compared the survival outcomes of patients with cervical cancer in FIGO 2018 stage IIIC with those in stages IIIA and IIIB. Studies focused on rare histopathological types were excluded. The statistical analyses were performed using Stata 17 software. The endpoints were overall survival (OS) and progression-free survival (PFS). RESULTS Ten retrospective cohort studies were eligible, involving 2113 (6.2%), 9812 (28.6%), 44 (0.1%), 10 171 (29.7%), 11 677 (34.1%) and 445 (1.3%) patients in stage IIIA, IIIB, IIIA&B, IIIC, IIIC1, and IIIC2, respectively. In the OS group, stage IIIC/C1 was significantly associated with superior survival compared with stage IIIA (hazard risk [HR] 0.62, 95% confidence interval [CI] 0.41-0.93, P = 0.022; I2 = 92.9%) and stage IIIB(A&B) (HR 0.56, 95% CI 0.44-0.71, P < 0.001; I2 = 94.0%). The FIGO 2018 stage IIIC2 was not associated with an increased mortality risk compared with stage IIIA and stage IIIB(A&B). In the PFS group, the outcome of FIGO 2018 stage IIIC/C1 was similar to stage IIIA (HR 0.66, 95% CI 0.27-1.64, P = 0.371; I2 = 65.6%), but better than stage IIIB(A&B) (HR 0.75, 95% CI 0.68-0.83, P < 0.001; I2 = 0.0%). The FIGO 2018 stage IIIC2 has similar PFS outcomes to stage IIIA and stage IIIB(A&B). CONCLUSION Our findings demonstrate that survival outcomes of stage IIIC are no worse than those of stage IIIA and stage IIIB in the 2018 FIGO cervical cancer staging system. In cervical cancer, FIGO 2018 stage IIIC1 has significantly better OS outcomes than stage IIIA and stage IIIB.

Abstract
Purpose To compare the oncologic outcomes of prophylactic extended-field radiation therapy (EFRT) and whole pelvic radiation therapy (WPRT) in cervical patients at high risk of para-aortic lymph node (PALN) recurrence. Patients and Methods From July 1999 to May 2022, a total of 115 patients with cervical cancer and high-risk features of PALN recurrence based on tumor markers, positive LNs and extensive parametrial invasion were retrospectively analyzed. All patients had received EFRT or WPRT at a dose of 39.6-45 Gy and concurrent chemotherapy. In EFRT, coverage was extended to include the para-aortic region below the level of the left renal vein or T12. Results Twenty-eight and 87 patients underwent EFRT and WPRT, respectively. For patients who survived, the median follow-up time was 60.8 months (range 9.2-131.6 months) in the EFRT group and 115.9 months (range 16.9-212.1 months) in the WPRT group. The 5-year overall survival (OS) and pelvic, extrapelvic and PALN recurrence rates were 87.7% vs 60.8% (p=0.019), 10.9% vs 25.3% (p=0.119), 18.1% vs 45.8% (p=0.011), and 0% vs 30.4% (p=0.005), respectively, between the EFRT and WPRT groups. Multivariate analysis revealed that EFRT and 2018 FIGO stage IV disease status were significant predictors of OS and extrapelvic recurrence. Conclusion Compared to WPRT, EFRT significantly improved OS and reduced extrapelvic and PALN recurrence in patients with cervical cancer with high-risk recurrence features.

Abstract
This review provides a practical approach to the imaging evaluation of patients with cervical cancer (CC), from initial diagnosis to restaging of recurrence, focusing on MRI and FDG PET. The primary updates to the International Federation of Gynecology and Obstetrics (FIGO) CC staging system, as well as these updates' relevance to clinical management, are discussed. The recent literature investigating the role of MRI and FDG PET in CC staging and image-guided brachytherapy is summarized. The utility of MRI and FDG PET in response assessment and posttreatment surveillance is described. Important findings on MRI and FDG PET that interpreting radiologists should recognize and report are illustrated. The essential elements of structured reports during various phases of CC management are outlined. Special considerations, including the role of imaging in patients desiring fertility-sparing management, differentiation of CC and endometrial cancer, and unusual CC histologies, are also described. Finally, future research directions including PET/MRI, novel PET tracers, and artificial intelligence applications are highlighted.

Abstract
PURPOSE The aim of this study was to compare the survival rates and toxicities of prophylactic extended-field radiation therapy (EFRT) and pelvic radiation therapy (PRT) among patients with cervical cancer with 2018 International Federation of Gynecology and Obstetrics (FIGO) stage IIIC1 disease. METHODS AND MATERIALS We retrospectively analyzed patients with 2018 FIGO stage IIIC1 disease who were treated with definitive concurrent chemoradiotherapy at our institute between 2011 and 2015. A dose of 50.4 Gy in 28 fractions was delivered to the pelvic region (by PRT) or the pelvic plus para-aortic lymph node region (by EFRT) with intensity modulated radiation therapy. The first-line regimen of concurrent chemotherapy was weekly cisplatin. RESULTS A total of 280 patients were included, with 161 patients treated with PRT and 119 patients treated with EFRT. After propensity score matching (1:1), 71 pairs of patients were selected. The respective 5-year rates of the patients treated with PRT and EFRT were 61.9% and 85.0% for overall survival (P = .025) and 53.0% and 77.9% for disease-free survival (DFS) (P = .004), respectively, after matching. In the subgroup analysis, patients were grouped into a high-risk group (122 patients) and a low-risk group (158 patients) based on 3 factors: positive common iliac lymph nodes, ≥3 pelvic lymph nodes, and 2014 FIGO stage IIIB disease. In both the high-risk and low-risk groups, EFRT significantly improved DFS compared with PRT. The rates of grade ≥3 chronic toxicities were 1.2% and 5.9% in the PRT and EFRT groups, respectively (P = .067). CONCLUSIONS In comparison to PRT, prophylactic EFRT was associated with improved overall survival, DFS, and para-aortic lymph node control in patients with cervical cancer with FIGO stage IIIC1 disease. The incidence of grade ≥3 toxicities was higher in the EFRT group than in the PRT group, although the difference was not significant.

BMC Cancer 2023; 23:481. [PMID: 37245053 DOI: 10.1186/s12885-023-10931-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2023] [Accepted: 05/08/2023] [Indexed: 05/29/2023] Open
Abstract
BACKGROUND This study aims to evaluate the clinical efficacy and side effects of setting up a high-risk clinical target volume (CTV-hr) alongside simultaneous integrated boost intensity-modulated radiotherapy (IMRT-SIB) in patients diagnosed with stage IIB-IVA cervical cancer. METHODS This study retrospectively analysed patients with stage IIB-IVA cervical cancer who received radical radiotherapy at the Affiliated Hospital of Qingdao University between November 2014 and September 2019. The patients were divided into experimental and control groups based on whether CTV-hr was set. All patients received a combined treatment of radiotherapy and chemotherapy. The dosage for paclitaxel was 135 mg/m2, while for cisplatin it was 75 mg/m2 or for carboplatin it was AUC 4-6, given in a cycle of 21 days. Radiotherapy (RT) included external beam radiation therapy (EBRT) and intracavitary brachytherapy (ICBT). In the control group, positive lymph nodes (GTV-n) were treated at a dose of 58-62 Gy/26-28 fractions(f), while clinical target volumes (CTV) were treated with a dose of 46-48 Gy/26-28f. The experimental group received a simultaneous integrated boost (SIB) to CTV-hr at a dose of 54-56 Gy/26-28f, with the same CTV and GTV-n as the control group. Both groups were combined with brachytherapy with a total dose (EQD2, the equivalent dose in 2 Gy/f) of 80-90 Gy. The study measured objective remission rate (ORR), 3-year progression-free survival (PFS) rate, 3-year overall survival (OS) rate, recurrence rate, and side effects as endpoints. RESULTS The study enrolled 217 patients, with 119 in the experimental group and 98 in the control group. Results showed that the experimental group had a higher 3-year OS rate (87.4% vs. 71.4%, p = 0.001) and 3-year PFS rate (72.3% vs. 51.0%, p = 0.000) compared to the control group. Additionally, the experimental group had significantly lower rates of overall recurrence (26.1% vs. 50.0%, p = 0.003), in-field recurrence (15.1% vs. 36.7%, p = 0.000), and out-field recurrence(13.4% vs. 35.7%, p = 0.000) compared to the control group. All observed differences were found to be statistically significant. However, the experimental and control groups had no statistically significant difference in ORR and radiological side effects, such as radiation cystitis and enteritis (p > 0.05). CONCLUSIONS Setting CTV-hr and performing IMRT-SIB on patients with stage IIB-IVA cervical cancer effectively increased the 3-year OS rate, 3-year PFS rate and reduced recurrence rate, with no significant differences in side effects.

Abstract
BACKGROUND The impact of para-aortic lymphadenectomy (PALD) on prognosis and quality of life (QoL) for IB2-IIA2 cervical cancer patients remain controversial. And whether intraoperative frozen pathology exam on common iliac lymph nodes could help predict para-aortic lymph node (PALN) metastasis was unanswered with high-level evidence. METHODS A multi-center, randomized controlled study is intended to investigate the effect of PALD on the prognosis and QoL in cervical cancer patients and to assess the value of intraoperative frozen pathological evaluation of common iliac nodes metastasis for the prediction of PALN metastasis. After choosing whether to receive intraoperative frozen pathological examination of bilateral common iliac lymph nodes, eligible patients will be randomly assigned (1:1) to receive PALD or not. The primary end point is 2-year progression-free survival (PFS). The secondary end points include 5-year PFS, 2-year overall survival (OS), 5-year OS, adverse events (AEs) caused by PALD, AEs caused by radiotherapy and QoL. A total of 728 patients will be enrolled from 8 hospitals in China within 3-year period and followed up for 5 years. TRIAL REGISTRATION Chinese Clinical Trial Register Identifier: ChiCTR2000035668.

Machine learning applied to MRI evaluation for the detection of lymph node metastasis in patients with locally advanced cervical cancer treated with neoadjuvant chemotherapy. Arch Gynecol Obstet 2022; 307:1911-1919. [PMID: 36370209 DOI: 10.1007/s00404-022-06824-6] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Accepted: 10/10/2022] [Indexed: 11/13/2022]
Abstract
PURPOSE Concurrent cisplatin-based chemotherapy and radiotherapy (CCRT) plus brachytherapy is the standard treatment for locally advanced cervical cancer (LACC). Platinum-based neoadjuvant chemotherapy (NACT) followed by radical hysterectomy is an alternative for patients with stage IB2-IIB disease. Therefore, the correct pre-treatment staging is essential to the proper management of this disease. Pelvic magnetic resonance imaging (MRI) is the gold standard examination but studies about MRI accuracy in the detection of lymph node metastasis (LNM) in LACC patients show conflicting data. Machine learning (ML) is emerging as a promising tool for unraveling complex non-linear relationships between patient attributes that cannot be solved by traditional statistical methods. Here we investigated whether ML might improve the accuracy of MRI in the detection of LNM in LACC patients. METHODS We analyzed retrospectively LACC patients who underwent NACT and radical hysterectomy from 2015 to 2020. Demographic, clinical and MRI characteristics before and after NACT were collected, as well as information about post-surgery histopathology. Random features elimination wrapper was used to determine an attribute core set. A ML algorithm, namely Extreme Gradient Boosting (XGBoost) was trained and validated with tenfold cross-validation. The performances of the algorithm were assessed. RESULTS Our analysis included n.92 patients. FIGO stage was IB2 in n.4/92 (4.3%), IB3 in n.42/92 (45%), IIA1 in n.1/92 (1.1%), IIA2 in n.16/92 (17.4%) and IIB in n.29/92 (31.5%). Despite detected neither at pre-treatment and post-treatment MRI in any patients, LNM occurred in n.16/92 (17%) patients. The attribute core set used to train ML algorithms included grading, histotypes, age, parity, largest diameter of lesion at either pre- and post-treatment MRI, presence/absence of fornix infiltration at pre-treatment MRI and FIGO stage. XGBoost showed a good performance (accuracy 89%, precision 83%, recall 78%, AUROC 0.79). CONCLUSIONS We developed an accurate model to predict LNM in LACC patients in NACT, based on a ML algorithm requiring few easy-to-collect attributes.

Abstract
Objective Lymph node metastasis (LNM) is the most important factor affecting survival in early-stage cervical cancer (CC). International Federation of Gynecology and Obstetrics revised the staging of CC in 2018 and reported LNM as a staging criterion. We investigated the preoperatively assessable risk factors associated with LNM in surgically treated stage IB1-IIA2 CC patients. Materials and Methods This was a retrospective cohort study of women who underwent radical hysterectomy and pelvic lymphadenectomy with or without para-aortic lymphadenectomy for CC stage IB1-IIA2 from 2004 to 2019. All patients included in this study were examined with speculum inspection, parametrial assessment by rectovaginal palpation under general anesthesia, transvaginal ultrasonography, magnetic resonance imaging (MRI), and chest radiography. Clinical staging was done according to the preoperative findings. MRI was used to measure tumor and lymph node dimensions. Results Out of the 149 women included in the study, 29 (19.4%) had LNM. Univariate analysis revealed that larger tumor size (≥30 mm), lymphovascular space invasion (LVSI) detected with diagnostic biopsy, parametrial involvement, and deep stromal invasion status were significantly different between the group with LNM and the group without LNM. In multivariate analysis, specific preoperative risk factors such as MRI based tumor diameter ≥30 mm and LVSI (+) on the diagnostic biopsy were found to be independent risk factors for LNM in the multivariate analysis. Conclusion The rate of LNM is high in patients with CC with a tumor size ≥30 mm and preoperative biopsy LVSI status even if they are clinically in early stages. Surgeons can take this into account while deciding between primary surgery and chemoradiotherapy in the treatment of CC.

Abstract
OBJECTIVE The aim of this study was to review the clinicopathological characteristics of small cell neuroendocrine cervical cancer (SCNEC) and to identify the optimal treatment. METHODS The Japanese Society of Gynecologic Oncology conducted a retrospective cohort study of SCNECs enrolled in the Gynecological Tumor Registry of the Japan Society of Obstetrics and Gynecology between 2004 and 2015. All cases were modified and unified by International Federation of Gynecology and Obstetrics 2008 (Union for International Cancer Control 7th edition). RESULTS There were 822 registered patients diagnosed with SCNEC from 2004 to 2015 which comprised 1.1% (822/73,698) of all uterine cervical cancer cases. Rates of lymph-node and distant metastasis were significantly higher in T1b2 (38.9% and 13.7%, respectively) than T1b1 (14.2% and 4.4%, respectively) (p<0.01). In IB2 and T1bN1M0 SCNEC, the 5-year survival rate with surgery followed by chemotherapy was significantly higher than that with surgery followed by radiation therapy/concurrent chemoradiation therapy (p<0.01). CONCLUSION SNCEC tumors >4 cm in size had greater rates of lymph-node and distant metastasis when compared with tumors ≤4 cm. Adjuvant chemotherapy, rather than radiotherapy, may improve prognosis after surgery in T1bN1M0 SCNEC.

Abstract
Objective We aimed to investigate the association of examined lymph node (ELN) number with lymph node status and long-term survival in FIGO stage IB-IIA cervical squamous cell carcinoma(CSCC) and to determine the minimum number of ELN associated with survival improvement. Method Data from the Surveillance, Epidemiology, and End Results Program (SEER) database of FIGO stage IB-IIA CSCC patients undergoing hysterectomy and pelvic lymphadenectomy in 2004-2016 were analyzed to explore the relationship between ELN number and lymph node status and overall survival (OS) by using the multivariable approach. The estimated probability of falsely identifying a patient as node-negative and the hazard ratios (HRs) for each ELN was fitted with a LOWESS smoother, and the structural breakpoints were determined. X-tile software was used to determine the optimal cutoff value for ELNs. Results A total of 2627 patients were analyzed. The optimal cutoff value of the ELN number was identified as 7 based on the results of X-tile software. The structural breakpoints according to the associations between the number of ELNs and the estimated risk of false-negative lymph node dissection and HRs for overall survival were 9 and 8, respectively. The multivariate analysis indicated that ELN number was an independent prognostic factor for OS, both as a continuous or categorical variable. To further explore the effect of more ELNs on survival, another cutoff value of 17 was chosen to compare the survival curves of patients. The multivariate-adjusted COX model showed that patients with ELN<8 had a significantly higher risk of death than those with ELN8-17 (HR=1.447, 95% CI =1.075-1.947, p=0.015), but there was no significant difference in overall survival between patients with ELN>17 and patients with ELN8-17 (HR=0.822, 95%CI =0.665-1.016, p=0.070). Conclusion A sufficient number of ELNs was associated with better long-term survival in FIGO stage IB-IIA CSCC. At least 8 ELNs need to be examined for prognostic stratification. Excessive lymph node dissection (ELN>17) may not confer additional survival benefits.

Abstract
Concomitant chemoradiotherapy is the standard treatment for locally advanced cervical cancer. Pelvic irradiation is commonly recommended for patients with negative para-aortic lymph nodes(PALNs). However, owing to the development of imaging-guided brachytherapy, distant failure has become the main failure pattern. The PALNs are a vital site of distant metastasis, and the para-aortic region may contain occult microscopic metastases that are barely detected owing to imaging technology restriction. The prognostic of patients who experienced PALN failure is dismal. Typically, there are four ways to decrease PALN failure. First, surgical staging can be performed to assess the occurrence of metastasis in the para-aortic region; however, the application of surgical staging is decreasing owing to controversial survival benefits and accompanying complications of surgery. Second, regular imaging surveillance and timely salvage of early recurrences could reduce PALN failure. Third, better systemic adjuvant therapy could be recommended since it has enormous potential to reduce distant metastases and improve overall survival. Fourth, performing prophylactic extended-field irradiation (EFI), including pelvic and para-aortic region irradiation, can sterilize occult microscopic metastases in the para-aortic region and improve survival. Prior investigations have revealed that prophylactic EFI could reduce PALN failure as well as distant metastasis and present the benefit of survival. Yet, owing to the serious morbidity induced by enlarged irradiation field in the era of conventional irradiation techniques, further research on EFI is stagnated. Nowadays, with the development of new technologies, intensity modulated radiation therapy can deliver a higher dose to tumors with acceptable toxicity. Prophylactic EFI regained attention. However, the inclusion criteria of prophylactic EFI in existing studies reveal great discrepancies. Thus, it is urgent to precisely identify indications for better survival and lower complications in patients with cervical cancer. In this review, we identify indications and summary guidelines for prophylactic EFI, which may provide a foundation for further trials and clinical applications.

Abstract
Background Patients with locally advanced cervical cancer without para-aortic lymph node metastases (PAO-LNM) at diagnosis who undergo concurrent chemoradiotherapy are at 4-11% risk of developing PAO-LNM during follow-up. Some studies suggest a beneficial influence of elective para-aortic radiotherapy (PAO-RT) on disease-free survival (DFS) in these patients. The aim of this study was to systematically review and meta-analyse literature on the impact of PAO-RT on DFS in cervical cancer patients. Methods A systematic search of PubMed/MEDLINE and EMBASE databases was performed. The analysis included intervention studies that reported on DFS in patients with cervical cancer who received chemotherapy and pelvic radiotherapy with or without PAO-RT. From each included study, relevant study characteristics and outcome data including the hazard ratio (HR) adjusted for potential confounders were extracted. An overall pooled adjusted hazard ratio (aHR) for DFS after PAO-RT versus no PAO-RT was calculated using a random-effects model. Results A total of 2,016 articles were evaluated. Eleven articles were included in the systematic review, of which 3 were appropriate for quantitative meta-analysis. Pooling of these 3 cohorts (including 1,113 patients) demonstrated a statistically significant association between PAO-RT and DFS (pooled aHR 0.87, 95% confidence interval: 0.79-0.97). No significant heterogeneity among reported aHRs was observed (I2 = 0.0%). Conclusions This meta-analysis suggests a modest but significant beneficial impact of elective para-aortic radiotherapy on DFS in patients with locally advanced cervical cancer who undergo concurrent chemoradiotherapy. This finding based on non-randomized studies provides an imperative for further investigation in prospective controlled trials.

Abstract
Background Lymph node metastasis (LNM) accounts for the most important route of metastasis for cervical cancer. Yet, the status of LNM is different in patients with similar clinico-pathological variables. It has been revealed that microRNAs are widely involved in the occurrence and development of various malignancies, and the tumor-suppressive or promoting effects of microRNA-99 (miR-99) family have been previously reported. This study sought to investigate the predictive value of miR-99a for lymphogenous spread and its effect on the survival of patients with early-stage cervical squamous cell cancer (CSCC). Methods Patients with stage IB squamous cervical cancer who were treated surgically between October 2015 and November 2018 were enrolled. A total of 21 formalin-fixed paraffin-embedded tissues of pathologically confirmed positive lymph nodes were retrieved, and an additional 21 tissues of negative lymph nodes from patients well-matched on baseline characteristics were collected as the control group. TaqMan real-time quantitative polymerase chain reaction was used to examine the expression levels of miR-99a in the samples. Differential expression levels of miR-99a were compared between the 2 groups using independent sample t-test. Furthermore, the associations between miR-99a expression level and clinico-pathological parameters of these 42 patients was evaluated by Chi-square test or Fisher's exact-probability method, and their effects on survival were assessed using Kaplan-Meier product-limit method. Results There were no significant differences in baseline clinico-pathological parameters between the 2 groups (P>0.05). The expression levels of miR-99a in the node-positive group and control group were 1.61±3.09 and 16.77±30.40, respectively (P=0.029). Downregulated expression of miR-99a was closely related to depth of invasion (DOI) and lymph-vascular space invasion (P<0.05). Univariate analysis revealed that downregulated miR-99a and deeper DOI were associated with worse 5-year disease-free survival, while multivariate analysis showed that only the expression level of miR-99a was an independent factor for disease-free survival (HR =0.120; 95% CI: 0.015-0.979; P=0.048). Patients with downregulated miR-99a tended to have more unfavorable overall survival, but the difference did not reach statistical significance. Conclusions MiR-99a plays an inhibitory role in the pathogenesis of lymph node metastasis and may serve as a novel prognostic biomarker for patients with CSCC.

[PMID: 35626385 PMCID: PMC9140083 DOI: 10.3390/diagnostics12051230] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2022] [Revised: 05/12/2022] [Accepted: 05/12/2022] [Indexed: 12/02/2022] Open
Abstract
The incidence of lymph node (LN) involvement and its prognostic value based on radiological imaging in stage IIB cervical cancer (CC) remains unclear, and evidence regarding oncological outcomes of patients with stage IIB CC with LN metastases is limited. In this study we retrospectively reviewed the incidence and prognostic significance of pretreatment radiologic LN status in 72 patients with clinical stage IIB CC (FIGO 2009), with or without radiologic evidence of LN enlargement. An enlarged LN was defined as a diameter > 10 mm on CT/MRI. Progression-free survival (PFS) and overall survival (OS) were assessed. Radiologic LN enlargement of >10 mm was observed in 45.8% of patients with stage IIB CC. PFS (p = 0.0088) and OS rates (p = 0.0032) were significantly poorer in the LN group (n = 33) than in the non-LN group (n = 39). Univariate Cox analysis revealed that LN > 10 mm contributed to a higher rate of recurrence and mortality. In conclusion, nearly half of the patients with clinical stage IIB CC had enlarged LNs (>10 mm) identified during pretreatment radiologic evaluation, which negatively impacted prognosis. Our findings highlight the need to incorporate CT- or MRI-based LN assessment before treatment for stage IIB CC.

Significance of histology and nodal status on the survival of women with early-stage cervical cancer: validation of the 2018 FIGO cervical cancer staging system. J Gynecol Oncol 2022; 33:e26. [PMID: 35320882 PMCID: PMC9024192 DOI: 10.3802/jgo.2022.33.e26] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2021] [Revised: 12/16/2021] [Accepted: 12/21/2021] [Indexed: 12/24/2022] Open
Abstract
OBJECTIVE To assess the efficacy of the FIGO 2018 classification system for nodal-specific classifications for early-stage cervical cancer; specifically, to examine the impact of nodal metastasis on survival and the effect of postoperative treatments, according to histological subtypes. METHODS This society-based retrospective observational study in Japan examined 16,539 women with the 2009 FIGO stage IB1 cervical cancer who underwent primary surgical treatment from 2004 to 2015. Associations of cause-specific survival (CSS) with nodal metastasis and postoperative adjuvant therapy were examined according to histology type (squamous cell carcinoma [SCC], n=10,315; and non-SCC, n=6,224). RESULTS The nodal metastasis rate for SCC was higher than that for non-SCC (10.7% vs. 8.3%, p<0.001). In multivariable analysis, the impact of nodal metastasis on CSS was greater for non-SCC tumors (adjusted-hazard ratio [HR], 3.11; 95% confidence interval [CI], 2.40-4.02) than for SCC tumors (adjusted-HR, 2.20; 95% CI, 1.70-2.84; p<0.001). Propensity score matching analysis showed significantly lower CSS rates for women with pelvic nodal metastasis from non-SCC tumors than from SCC tumors (5-year CSS rate, 75.4% vs. 90.3%, p<0.001). The CSS rates for women with nodal metastasis in SCC histology were similar between the postoperative concurrent chemoradiotherapy/radiotherapy and chemotherapy groups (89.2% vs. 86.1%, p=0.42), whereas those in non-SCC histology who received postoperative chemotherapy improved the CSS (74.1% vs. 67.7%, p=0.043). CONCLUSION The node-specific staging system in the 2018 FIGO cervical cancer classification is applicable to both non-SCC tumors and SCC tumors; however, the prognostic significance of nodal metastases and efficacy of postoperative therapies vary according to histology.

Abstract
We herein report a retrospective analysis of the efficacy of a combination therapy of pelvic irradiation that excluded the common iliac lymph nodes region and image-guided brachytherapy (IGBT) for non-bulky (≤4 cm) cervical cancer. Thirty-three patients with stage I-II cervical squamous cell carcinoma (≤4 cm) and without pelvic/para-aortic lymphadenopathy who were treated with definitive radiotherapy alone between February 2009 and September 2016 were included. The radiotherapy consisted of CT-based small-pelvis irradiation (whole pelvis minus common iliac lymph node area) of 20 Gy/10 fractions followed by pelvic irradiation with a midline block of 30 Gy/15 fractions and IGBT of 24 Gy/4 fractions (6 Gy/fraction for high-risk [HR] clinical target volume [CTV] D90%). In-room computed tomography (CT) imaging with applicator insertion was used for brachytherapy planning, with physical examinations and diagnostic magnetic resonance imaging (MRI) also being referred to for determination of HR CTV. Over a median follow-up of 60.5 months (range, 7-89), two patients developed distant recurrence and one developed local and distant recurrence. Two patients died from cervical cancer, one from hepatocellular carcinoma and one from non-cancerous disease. The 2/5-year local control (LC), progression-free survival (PFS) and overall survival (OS) rates were 100%/96.7%, 93.8%/90.6% and 93.9%/93.9%, respectively. No pelvic/para-aortic lymph node recurrence was observed. There were no late complications of grade 3 or higher in the small bowel, large bowel/rectum, or bladder. Our results suggest that a combination therapy of IGBT plus small-pelvis irradiation excluding common iliac lymph nodes provides reasonable clinical outcomes and can be a treatment option in non-bulky (≤4 cm) cervical squamous cell carcinoma.

Abstract
AbstractRadical hysterectomy (RH) is a standard treatment for early-stage cervical cancer. This surgery extirpates the uterus along with the paracervical tissues, vagina, and the paracolpium to achieve local control. Pelvic lymphadenectomy is a critical component of RH performed for regional control. A clear understanding of pelvic anatomy is critical to safely performing a RH and achieving optimal oncological and functional outcomes. The various surgical steps can damage the pelvic autonomic nerves, and a systematic nerve-sparing technique is used for the preservation of autonomic nerves. There is an intricate vascular network in the lateral paracervix (cardinal ligament) and the pelvic sidewall. We need to comprehend the three-dimensional structure of the vascular and nerve anatomy in the pelvis to perform RH effectively and safely. We can create six spaces around the uterine cervix, including the paravesical spaces, pararectal spaces, a vesicovaginal space, and a rectovaginal space to reveal the target of extirpation. It is critical to find the proper tissue plane separated by the layers of membranous connective tissue (fascia), in order to minimize intraoperative bleeding.

Abstract
OBJECTIVE The circumflex iliac nodes distal to the external iliac nodes are frequently removed when bilateral pelvic lymphadenectomy is performed in patients with cervical cancer. The objective of this systematic review was to assess the incidence of metastasis in the circumflex iliac nodes in patients with cervical cancer. METHODS PubMed/Medline, ClinicalTrials, Embase, Cochrane Central Register of Controlled Trials, Scopus, and Ovid databases were searched from inception to May 2021. We included articles published in English language reporting all types of studies, except for case reports and commentaries. Abstracts and unpublished studies were excluded. The inclusion criteria were diagnosis of cervical cancer, FIGO 2009 stages IA-IIB, squamous cell carcinoma, adenocarcinoma or adenosquamous carcinoma, and primary surgery including pelvic lymph node dissection. RESULTS A total of 3037 articles were identified. Overall, 1165 eligible patients from four studies were included in the analysis. A total of 696 (59.7%) patients had early-stage disease (FIGO 2009 stages IA, IB1, IIA1). The median number of extracted circumflex iliac nodes, which was reported in two studies, was one (range not reported) and three (range 1-13). The positive lymph node rate for the entire population and circumflex iliac node involvement were 26.9% and 3.1%, respectively. Isolated metastases were reported for 904 patients (three studies) and in one patient nodal spread was detected (0.11%). CONCLUSION The rate of isolated metastases in circumflex iliac nodes is small and excision of these lymph nodes as part of routine lymphadenectomy should be avoided.

Abstract
This study investigated the usefulness of conventional ultrasound (US) and contrast-enhanced ultrasound (CEUS) in distinguishing metastasis of pelvic sentinel lymph nodes (SLNs) in patients with gynecological cancer. We examined 74 SLNs of patients with endometrial cancer (n = 26) and cervical cancer (n = 11). Patients underwent US and CEUS followed by SLN biopsy; US and CEUS results were evaluated visually and quantitatively and compared between pathological metastasis-negative and -positive groups. To support CEUS results, the microvessel density of SLNs was evaluated immunohistochemically. Seventeen positive and 40 negative SLNs were evaluable. Margin and enhancement patterns by visual assessment revealed significant differences (p = 0.046 and 0.022, respectively). In quantitative time-intensity curve analyses, the weakest peak intensities (PImin), PI ratio and PI difference indicated significant differences (p = 0.045, p < 0.001 and p < 0.001, respectively). The areas under the receiver operating characteristic curves (AUCs) were 0.64, 0.82 and 0.83, respectively. The most effective PI ratio from the AUC was 1.3 (sensitivity = 82%, specificity = 70%), and the PI difference from the AUC was 20 (sensitivity = 88%, specificity = 70%). Microvessel density was significantly lower in metastatic lesions than in other areas. The quantitative analysis of CEUS seemed to be a reasonable method for distinguishing lymph node metastasis in patients with gynecological cancer.

Abstract
AIM To investigate the clinical significance of uterine corpus involvement in patients with surgically treated cervical cancer. METHODS Patients (n = 354) with clinical early-stage (stage IB1-IIA2) cervical cancer who underwent radical hysterectomy and pelvic ± paraaortic lymphadenectomy were evaluated. RESULTS Uterine invasion was detected in 60 (16.9%) patients. Patients with uterine invasion had a higher rate of pelvic lymph node metastasis than those without uterine invasion (35% vs 22.8%, p = 0.046). In multivariate analysis, no statistically significant difference was identified between patients with and without uterine invasion for pelvic lymph node metastasis (p = 0.953). Uterine invasion was identified as an independent risk factor for paraaortic lymph node metastasis in multivariate analysis (p = 0.012). The presence of pelvic lymph node metastasis was found to be another significant predictor of paraaortic lymph node involvement (p = 0.022). In addition, uterine invasion and lymph node metastasis were identified as an independent risk factors regarding poor prognosis in cancer-specific survival (hazard ratio [HR]: 4.537; 95% confidence interval [CI], 1.304-15.782; p = 0.017 and HR: 5.598; 95% CI, 1.581-19.823; p = 0.008, respectively). CONCLUSIONS Uterine invasion is an independent predictor of decreased survival and the presence of paraaortic lymph node metastasis in cervical cancer. The presence of the uterine invasion in cervical cancer should be considered as a poor prognostic factor in the decision of treatment.

Abstract
International Federation of Gynecology and Obstetrics (FIGO) staging, which is the fundamentally important cancer staging system for cervical cancer, has changed in 2018. New FIGO staging includes considerable progress in the incorporation of imaging findings for tumour size measurement and evaluating lymph node (LN) metastasis in addition to tumour extent evaluation. MRI with high spatial resolution is expected for tumour size measurements and the high accuracy of positron emmision tomography/CT for LN evaluation. The purpose of this review is firstly review the diagnostic ability of each imaging modality with the clinical background of those two factors newly added and the current state for LN evaluation. Secondly, we overview the fundamental imaging findings with characteristics of modalities and sequences in MRI for accurate diagnosis depending on the focus to be evaluated and for early detection of recurrent tumour. In addition, the role of images in treatment response and prognosis prediction is given with the development of recent technique of image analysis including radiomics and deep learning.

Abstract
Cervical cancer is the fourth most common neoplasm in women. In locally advanced cervical cancers, the international guidelines recommend nodal aortic assessment. Two techniques have been described to perform laparoscopic aortic lymphadenectomy: transperitoneal laparoscopic lymphadenectomy (TLL) and extraperitoneal laparoscopic lymphadenectomy (ELL). This meta-analysis aims to compare the surgical outcomes of TLL and ELL for staging purposes. The systematic review was carried out in agreement with the preferred reporting items for systematic reviews and meta-analyses statement (PRISMA). Two hundred and twenty studies were analyzed, and 19 studies were included in the review (7 for TLL and 12 for ELL group). 1112 patients were included in the analysis: 390 patients were included in group 1 and 722 patients in group 2.38 patients (9.7%) in the TLL group and 69 (9.5%) patients in the ELL group developed major complications. The analysis of all complications (intraoperative and postoperative) rate through pooled analysis did not show a significant difference between the two groups (p = 0.979), although a significantly higher intraoperative complication rate (p = 0.018) occurred in the TLL group compared to ELL. No significant differences were found between groups for BMI (p = 0.659), estimated blood loss (p = 0.889), length of stay (p = 0.932), intraoperative time (p = 0.932), conversion to laparotomy rate (p = 0.404), number of lymph node excised (p = 0.461) and postoperative complication (p = 0.291). TLL approach shows a higher rate of intraoperative complications, while no significant difference was found between the two techniques when postoperative complications were analyzed.

Abstract
OBJECTIVE The Japan Society of Gynecologic Oncology published the first guidelines for the treatment of cervical cancer in 2007. The aim of this research was to evaluate the influence of the introduction of the first guideline on clinical trends and outcomes of patients with early-stage cervical cancer who underwent surgery. METHODS This analysis included 9,756 patients who were diagnosed based on the pathological Tumor-Node-Metastasis (pTNM) classification (i.e., pT1b1, pT1b2, pT2b and pN0, pN1, pNX) and received surgery as a primary treatment between 2004 and 2009. Data of these patients were retrospectively reviewed, and clinicopathological trends were assessed. The influence of the introduction of the guideline on survival was determined by using a competing risk model. RESULTS For surgery cases, the estimated subdistribution hazard ratio (HR) by the competing risk model for the influence of the guideline adjusted for age, year of registration, pT classification, pN classification, histological type, and treatment methods was 1.024 (p=0.864). Following the introduction of the first guideline in 2007, for patients with lymph node metastasis, the use of chemotherapy (CT) as a postsurgical therapy increased, whereas that of concurrent chemoradiotherapy (CCRT)/radiotherapy (RT) decreased (p<0.010). For pN1 cases, the estimated subdistribution HR by the competing risk model for the influence of the guideline was 1.094 (p=0.634). There was no significance in the postsurgical therapy between CT and CCRT/RT (p=0.078). CONCLUSIONS Survival of surgical cases was not improved by the introduction of the guidelines. It is necessary to consider more effective postsurgical therapy for high-risk early-stage cervical cancer.

[PMID: 33933005 PMCID: PMC8088051 DOI: 10.1186/s12885-021-08208-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2020] [Accepted: 04/18/2021] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND The assessment of retroperitoneal lymph node status in patients with locally advanced cervical cancer is still a problem. This study aimed to explore the choice of these assessment methods. METHODS Laparoscopic retroperitoneal lymphadenectomy was performed in 96 patients with advanced cervical cancer. The positive rates of lymph node metastasis were analyzed. The values of computed tomography lymph node minimum axial diameter (MAD) and squamous cell carcinoma antigen (SCC-Ag), and their combination in predicting retroperitoneal lymph node metastasis were compared. High-risk factors for common iliac lymph node (CILN) and/or para-aortic lymph node (PALN) metastasis were analyzed. RESULTS The lymph node metastasis rate was 62.50% and the CILN and/or PALN metastasis rate was 31.25%. Overall, 96 patients had 172 visible lymph nodes. The positive rate of lymph node metastasis was significantly higher in the MAD ≥1.0 cm group (83.33%) than in the 0.5 cm ≤ MAD < 1.0 cm group (26.82%). The critical values of MAD and SCC-Ag in determining lymph node metastasis were 1.0 cm and 5.2 ng/mL, respectively. The accuracy, specificity, and Youden index of MAD ≥1.0 cm combined with SCC-Ag ≥ 5.2 ng/mL for evaluating lymph node metastasis were 75.71%, 100%, and 0.59, respectively, and were significantly different from the values for the MAD ≥1.0 cm (72.09%, 80.56%, and 0.47, respectively) and SCC-Ag ≥ 5.2 ng/mL (71.43%, 68.97%, and 0.42, respectively) groups. Correlation analysis showed that non-squamous cell carcinoma, pelvic lymph node (PLN) MAD ≥1.0 cm plus number ≥ 2, and 1 PLN MAD ≥1.0 cm with CILN and/or PALN MAD 0.5-1.0 cm were risk factors for CILN and/or PALN metastasis. CONCLUSION Patients with MAD ≥1.0 cm and SCC-Ag ≥ 5.2 ng/mL, as well as high risk factors for CILN and/or PALN metastasis, should undergo resection of enlarged lymph nodes below the common iliac gland and lymphadenectomy of CILN/PALN to reduce tumor burden and to clarify lymph node metastasis status for accurate guidance in follow-up treatment. Patients with MAD < 1.0 cm and SCC-Ag < 5.2 ng/mL may be treated with chemoradiotherapy directly based on imaging, given the low lymph node metastasis rate.

Abstract
PURPOSE To clarify the prognostic value of the number of metastatic lymph nodes (mLNs) in squamous and non-squamous histologies among women with node-positive cervical cancer. METHODS One hundred ninety-one node-positive cervical cancer patients who had undergone radical hysterectomy plus systematic pelvic and para-aortic lymphadenectomy followed by concurrent radiochemotherapy were retrospectively reviewed. The prognostic value of the number of mLNs was investigated in squamous cell carcinoma (SCC) v (n = 148) and non-SCC (n = 43) histologies separately with univariate log-rank test and multivariate Cox regression analyses. RESULTS In SCC cohort, mLNs > 2 was significantly associated with decreased 5-year disease-free survival (DFS) [hazard ratio (HR) = 2.06; 95% confidence interval (CI) 1.03-4.09; p = 0.03) and overall survival (OS) (HR = 2.35, 95% CI 1.11-4.99; p = 0.02). However mLNs > 2 had no significant impact on 5-year DFS and 5-year OS rates in non-SCC cohort (p = 0.94 and p = 0.94, respectively). We stratified the entire study population as SCC with mLNs ≤ 2, SCC with mLNs > 2, and non-SCC groups. Thereafter, we compared survival outcomes. The non-SCC group had worse 5-year OS (46.8% vs. 85.3%, respectively; p < 0.001) and 5-year DFS rates (31.6% vs. 82.2%, respectively; p < 0.001) when compared to those of the SCC group with mLNs ≤ 2. However, the non-SCC group and the SCC group with mLNs > 2 had similar 5-year OS (46.8% vs. 65.5%, respectively; p = 0.16) and 5-year DFS rates (31.6% vs. 57.5%, respectively; p = 0.06). CONCLUSION Node-positive cervical cancer patients who have non-SCC histology as well as those who have SCC histology with mLNs > 2 seem to have worse survival outcomes when compared to women who have SCC histology with mLNs ≤ 2.

Abstract
BACKGROUND/AIM This study aimed to evaluate the outcome of radiation therapy for patients with distant lymph node (LN) metastases, without organ metastases from uterine cervical cancer (UCC). PATIENTS AND METHODS Twenty-six patients with UCC with distant LN metastases received radiotherapy and were retrospectively analyzed. The sites of distant LN metastasis were as follows; Supraclavicular in 19, inguinal in nine, axillary in four, and others in three. The mean dose prescribed for these was 50 (range=40-60) Gy. RESULTS The 2-year overall, cause-specific, and progression-free survival, and local control of primary tumor rates were 51.3%, 51.3%, 46.9%, and 67.9%. In multivariate analysis, performance status ≥1 (p=0.007), para-aortic LN metastases (p=0.001), and lack of high-dose-rate intracavitary brachytherapy (p=0.033) were significantly associated with poor overall survival. Performance status ≥1 (p=0.004), and para-aortic LN metastases (p=0.014) were significantly associated with poor cause-specific survival. CONCLUSION This study demonstrated favorable local control in patients with UCC with distant LN metastases.

False negative rate at 18F-FDG PET/CT in para-aortic lymphnode involvement in patients with locally advanced cervical cancer: impact of PET technology. BMC Cancer 2021; 21:135. [PMID: 33549033 PMCID: PMC7866875 DOI: 10.1186/s12885-021-07821-9] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2020] [Accepted: 01/19/2021] [Indexed: 11/25/2022] Open
Abstract
Background The identification of factors responsible for false negative (FN) rate at 18F- Fluorodeoxyglucose (FDG) Positron Emission Tomography /Computed Tomography (PET/CT) in para-aortic (PA) lymph nodes in the presurgical staging of patients with locally advanced cervical cancer (LACC) is challenging. The aim of this study was to evaluate the impact of PET/CT technology. Methods A total of 240 consecutive patients with LACC (International Federation of Gynecology and Obstetrics, FIGO, stage IB2-IVA) and negative Magnetic Resonance Imaging (MRI) and/or Computed Tomography (CT) and negative 18F-FDG PET/CT in the PA region, undergoing laparoscopic PA lymphadenectomy before chemoradiotherapy were included. The FN rate in patients studied with Time of flight (TOF) PET/CT (TOF PET) or non-Time of flight PET/CT (no-TOF PET) technology was retrospectively compared. Results Patients presented with FIGO stage IB (n = 78), stage IIA-B (n = 134), stage III (n = 18) and stage IVa (n = 10), squamous cell carcinoma (n = 191) and adenocarcinoma (n = 49). 141/240 patients were evaluated with no-TOF PET/CT and 99/240 with TOF PET/CT. Twenty-two patients (9%) had PA nodal involvement at histological analysis and considered PET/CT FN findings. The FN rate was 8.5% for no-TOF PET and 10% for TOF PET subgroup respectively (p = 0.98). Ninety patients (38%) presented with pelvic node uptakes at PET/CT. The FN rate in the PA region was 18% (16/90) and 4% (6/150) in patients with and without pelvic node involvement at PET/CT respectively (19 vs 3% for no-TOF PET and 17 vs 5% for TOF PET subgroup). Conclusions In LACC, FN rate in PA lymph nodes detection is a clinical issue even for modern PET/CT, especially in patients with pelvic uptake. Surgical lymphadenectomy should be performed in case of negative PET/CT at PA level in these patients, while it could be discussed in the absence of pelvic uptake.

Abstract
OBJECTIVE To analyze the predictive factors for non-sentinel lymph node (non-SLN) metastasis in early-stage cervical cancer. METHODS We analyzed a series of 113 patients who underwent sentinel lymph node (SLN) mapping for cervical cancer. The SLNs were examined by immunohistochemistry (IHC) when the hematoxylin-eosin stain was negative. RESULTS The overall bilateral detection rate was 81.5%, with a median of two SLNs resected. The study ultimately included 92 patients with SLNs that were mapped who had also undergone systematic pelvic lymph node dissection. Thirteen (14.1%) patients had positive SLNs, with a median of one positive SLN. Regarding the size of SLN metastasis, one (1.1%) had isolated tumor cells (ITC), seven (7.6%) had micrometastases, and five (5.4%) had macrometastases. Notably, 46.1% (6/13) had lymph node metastases detected only after IHC. Five (38.5%) cases had positive non-SLNs, with a median count of one positive lymph node. Parametrial invasion was the only risk factor for positive non-SLN (p = .045). Regarding the size of SLN metastasis, non-SLN involvement was present in the only case with ITC (1/1), 42.9% (3/7) of cases with micrometastases, and in 20% (1/5) with macrometastases. CONCLUSIONS Our data suggest that parametrial invasion correlates with the risk of non-SLN metastasis in cervical cancer.

Abstract
OBJECTIVE To identify patterns of therapy failure after radiotherapy in Chinese patients with locally advanced cervical cancer (LACC). METHODS A retrospective study was conducted at a Chinese hospital from June 2012 to July 2018. All analyses were done using SPSS 26. RESULTS 105 patients with treatment failure were included. After a median follow-up of 27 months (range 10-82), the 3-year survival rate after therapy failure was 19.4%. In multivariate analysis, squamous cell carcinoma antigen (SCC-Ag) <4 ng/mL (p < 0.001) and disease-free interval >12 months (p = 0.013) showed significant survival benefits. We identified 3 types of failure: distant lymph node metastasis (n = 50), hematogenous metastasis (n = 53) and pelvic failure (n = 48). Most metastatic para-aortic lymph nodes (PALN) were inferior to the level of left renal hilum (84.8%, n = 28). A total of 80% of patients with supraclavicular lymph nodes (SCLN) metastasis ignored imaging on supraclavicular region. For solitary SCLN or lung metastasis, the prognosis was better than that combined with other sites failure, respectively (p = 0.005; p = 0.001). Many patients with central sites recurrence received insufficient doses of intracavitary brachytherapy (IBT) for low tolerance to pain. CONCLUSION The distribution of metastatic PALN is asymmetrical and optimizing clinical target volume to minimize toxicity of para-aortic radiation is necessary. The effect of ultrasonography as preliminary screening and follow-up means on SCLN metastasis can be expected. Pain management and psychological interventions are essential for patients receiving IBT.

Abstract
Pelvic lymphadenectomy is a common surgical procedure in gynecologic oncology. Pelvic lymph node dissection is performed for all types of gynecological malignancies to evaluate the extent of a disease and facilitate further treatment planning. Most studies examine the lymphatic spread, the prognostic, and therapeutic significance of the lymph nodes. However, there are very few studies describing the possible surgical approaches and the anatomical variations. Moreover, a correlation between anatomical variations and lymphadenectomy in the pelvic region has never been discussed in medical literature. The present article aims to expand the limited knowledge of the anatomical variations in the pelvis. Anatomical variations of the ureters, pelvic vessels, and nerves and their significance to pelvic lymphadenectomy are summarized, explained, and illustrated. Surgeons should be familiar with pelvic anatomy and its variations to safely perform a pelvic lymphadenectomy. Learning the proper lymphadenectomy technique relating to anatomical landmarks and variations may decrease morbidity and mortality. Furthermore, accurate description and analysis of the majority of pelvic anatomical variations may impact not only gynecological surgery, but also spinal surgery, urology, and orthopedics.

Abstract
Objectives This study aimed to assess the effect of neoadjuvant chemotherapy (NACT) on the rate of lymph node metastasis (LNM) in FIGO stage IB1-IIB cervical cancer patients and compare the LNM between NACT plus surgery and surgery only. Methods We identified 34 eligible studies in PubMed, Web of Science, Cochrane Library, and EMBASE from inception to July 27, 2019. Data analyses were performed by Stata (version 13) and Revman (version 5.3). Results In these 34 included studies, the pooled incidence of LNM was estimated as 23% (95% CI, 0.20-0.26; I2 = 79.6%, P<0.001). In the subgroup analysis, we identified five factors, including study type, year of publication, continents from which patients came, histological type and the FIGO stage. When taking FIGO stage into consideration, the LNM rate was 13% in stage IB (95% CI: 0.10-0.15; I2 = 5.5%, P=0.385), 23% in stage IIA (95% CI: 0.18-0.28; I2 = 0%, P=0.622), and 27% in stage IIB (95% CI: 0.20-0.33; I2 = 0%, P=0.898), respectively. Through the comparison between NACT plus surgery and surgery only based on the six randomized controlled trials, the incidence of positive lymph nodes was lower in patients receiving NACT plus surgery than surgery only (RR=0.57, 95% CI: 0.39-0.83; I2 = 60.5%, P=0.027). The 5-year OS was higher in the NACT + surgery group than surgery-only group (RR=1.13, 95% CI: 1.03-1.23; I2 = 0.0%, P=0.842). Conclusions Among cervical cancer in stage IB1-IIB, the preoperative NACT plus radical surgery resulted in a 23% probability of LNM, which was lower than those receiving radical surgery only. In stage IIA and IIB, the effect of NACT to reduce LNM was more obvious.

Abstract
OBJECTIVE We aim to describe the false negative (FN) and false positive (FP) rates of preoperative cross-sectional imaging (PCI) prior to radical surgery for cervical cancer. METHODS A retrospective cohort study of patients who underwent radical hysterectomy for early-stage cervical cancer from January 2010 until December 2017 at a single tertiary care center was performed. Patients were included if they underwent preoperative PCI and radical surgery. Patient demographics and clinicopathologic information were recorded from medical record review. Descriptive statistics were used. RESULTS Overall, 106 patients met inclusion criteria. Eighty-four percent (89/106) of patients had no suspicion for metastatic disease on PCI, while 16% (17/106) had suspicion for metastatic disease. Of the 89 without suspicion for metastatic disease on PCI, 16% (14/89) had a false negative study with metastatic disease identified on final surgical pathology. False negative rates by modality were 16% (11/70) for PET/CT and 6% (2/33) for diagnostic CT. Of the 17 cases with suspicion for metastatic disease on imaging, 53% (9/17) were false positive studies with no metastatic disease identified histologically. False positive rates by modality were 7% (5/70) for PET/CT and 12% (4/33) for diagnostic CT. CONCLUSION PCI is a tool to help identify patients who are optimal candidates for radical surgery. In this sample, the false negative rate was 16%, and false positive rate was 53% for PCI among women who underwent primary radical surgery. Further study is needed to explore preoperative testing that may more accurately identify optimal surgical candidates.

Abstract
PURPOSE We aimed to assess the impact of low-volume metastasis (micrometastasis and isolated tumor cells) on disease-free survival (DFS) of women with early-stage cervical cancer. METHODS Women with clinically suspected stage 1A-IB2 (FIGO 2018 classification) disease who underwent retroperitoneal nodal staging between October 2010 and April 2018, were retrospectively analyzed. The group of women who had undergone lymphadenectomy and standard node pathologic analysis (H&E group), were compared to the group undergoing sentinel node mapping (SLN) and ultrastaging with or without lymphadenectomy (ultrastaging group). At a median follow-up of 45 months, the DFS curves were analyzed. RESULTS Overall, 573 patients were revised (272 in the H&E group and 302 in the ultrastaging group). Eighty-five patients presented lymph node metastasis (32 in H&E, 53 in ultrastaging). Ultrastaging protocol increased the rate of low-volume metastasis by 5.6%. Twenty patients showed exclusive micrometastasis or ITC's. Seventy-three recurrences occurred (35 in H&E, 38 in ultrastaging). Only 1 out of 53 patients in the ultrastaging group (1.9%) presented with micrometastasis recurred. The 3-year disease-free survival was 89% for the H&E group, and 88% for the ultrastaging group, respectively (p = 0.175). CONCLUSION Ultrastaging analysis allowed increasing the detection of low volume metastasis in women with early-stage cervical cancer. However, the type of nodal staging did not have an impact on patients' 3-year disease-free survival.

Abstract
OBJECTIVE The prognostic impact of surgical paraaortic staging remains unclear in patients with locally advanced cervical cancer (LACC). The objective of our study was to evaluate the results of the surgical technique of preoperative aortic lymphadenectomy in LACC related to tumor burden and disease spread to assess its influence on survival. METHODS Data of 1,072 patients with cervical cancer were taken from 11 Spanish hospitals (Spain-Gynecologic Oncology Group [GOG] working group). Complete aortic lymphadenectomy surgery (CALS) was considered when the lymph nodes (LNs) were excised up to the left renal vein. The extent of the disease was performed evaluating the LNs by calculating the geometric means and quantifying the log odds between positive LNs and negative LNs. The Kaplan-Meier method was used to estimate the survival distribution. A Cox proportional hazards model was used to account for the influence of multiple variables. RESULTS A total of 394 patients were included. Pathological analysis revealed positive aortic LNs in 119 patients (30%). LODDS cut-off value of -2 was established as a prognostic indicator. CALS and LODDS <-2 were associated with better disease free survival and overall survival than suboptimal aortic lymphadenectomy surgery and LODDS ≥-2. In a multivariate model analysis, CALS is revealed as an independent prognostic factor in LACC. CONCLUSION When performing preoperative surgical staging in LACC, it is not advisable to take simple samples from the regional nodes. Radical dissection of the aortic and pelvic regions offers a more reliable staging of the LNs and has a favorable influence on survival.

UGT1A1 polymorphism has a prognostic effect in patients with stage IB or II uterine cervical cancer and one or no metastatic pelvic nodes receiving irinotecan chemotherapy: a retrospective study. BMC Cancer 2020; 20:729. [PMID: 32758288 PMCID: PMC7405427 DOI: 10.1186/s12885-020-07225-1] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2020] [Accepted: 07/27/2020] [Indexed: 12/24/2022] Open
Abstract
Background Uridine diphosphate glucuronosyltransferase 1 family polypeptide A1 (UGT1A1) is a predictive biomarker for the side-effects of irinotecan chemotherapy, which reduces the volume of tumors harboring UGT1A1 polymorphisms. We aimed to determine whether UGT1A1 polymorphisms can predict progression-free survival in patients with local cervical cancer treated with irinotecan chemotherapy. Methods We retrospectively analyzed the data of 51 patients with cervical cancer treated at a single institution between 2010 and 2015. All patients were diagnosed with 2009 International Federation of Gynecology and Obstetrics (FIGO) stage IB1, IB2, IIA, or IIB squamous cell carcinoma, underwent radical hysterectomy, and received irinotecan chemotherapy as neoadjuvant and/or adjuvant treatment. All patients were examined for irinotecan side effects using UGT1A1 tests. Conditional inference tree and survival analyses were performed considering the FIGO stage, age, the UGT1A1 status, and the number of metastatic lymph nodes to determine primary factors associated with progression-free survival. Results The tree-structured survival model determined high recurrence-risk factors related to progression-free survival. The most relevant factor was ≥2 metastatic lymph nodes (p = 0.004). The second most relevant factor was UGT1A1 genotype (p = 0.024). Among patients with ≤1 metastatic lymph node, those with UGT1A1 polymorphisms benefited from irinotecan chemotherapy and demonstrated significantly longer progression-free survival (p = 0.020) than those with wild-type UGT1A1. Conclusions Irinotecan chemotherapy might be beneficial in patients with cervical cancer, UGT1A1 polymorphisms, and ≤ 1 metastatic lymph nodes.

Abstract
Objective: Previous studies have shown that prophylactic extended-field irradiation can reduce para-aortic lymph node failure (PALNF) rates in patients with cervical cancer. As such, this type of irradiation may particularly benefit patients with a high risk of PALNF. In the present study, we analyzed the risk factors for PALNF in patients with cervical cancer treated with pelvic irradiation in order to identify potential indications of prophylactic extended-field irradiation. Methods: We evaluated patients with 2018 FIGO stage IB3-IIIC1 cervical cancer who were treated with definitive pelvic radiotherapy or concurrent chemoradiotherapy at our institution between 2011 and 2014. Univariate and multivariate analyses were performed to identify risk factors for PALNF. Results: We included 572 patients in the study. The median follow-up period was 37.9 months. Eighteen patients (3.1%) first site of tumor relapse was the para-aortic lymph nodes, and thus showed PALNF. Using multivariate Cox regression analysis, we identified two significant risk factors for PALNF: tumor extension to the pelvic wall (hazard ratio, HR 3.60, p=0.026) and ≥ 2 pelvic MLNs (HR 5.30, p=0.005). For patients with and without risk factors, the 3-year overall survival, disease-free survival, and PALNF rates were 77.3% and 90.1% (p<0.001), 56.4% and 83.1% (p<0.001), and 12.0% and 2.3% (p<0.001), respectively. Conclusion: Tumor extension to the pelvic wall and ≥ 2 pelvic MLNs are positively associated with PALNF after pelvic irradiation in patients with cervical cancer. Further trials will be required to validate whether patients with these two risk factors may benefit from prophylactic extended-field irradiation.

Abstract
OBJECTIVES To assess the diagnostic accuracy of magnetic resonance imaging (MRI) for detecting myometrial invasion, cervical invasion, and lymph node metastases in endometrial cancer. MATERIALS AND METHODS A systematic literature search was performed in PubMed, Embase, Cochrane Library, Web of Science, and Clinical trials. The methodological quality of each study was assessed by using the standard Quality Assessment of Diagnostic Accuracy Studies-2. Statistical analysis included evaluating publication bias, assessing threshold effect, exploring heterogeneity, pooling data, meta-regression, forest plot, and summary receiver-operating characteristics curves construction. RESULTS Fourteen studies could be analyzed. For detecting deep myometrial invasion, the pooled sensitivity and specificity were 0.79 and 0.81 respectively, and patients younger than 60 years old demonstrated higher sensitivity (0.84) and specificity (0.90). The diagnostic accuracy is highest by jointly using T2-weighted image, dynamic contrast-enhanced MRI, and diffusion weighted imaging to detect the deep myometrial invasion. There were low sensitivity and high specificity for the diagnosis of cervical invasion (0.53, 0.95), cervical stromal invasion (0.50, 0.95), pelvic or/and para-aortic lymph node metastases (0.59, 0.95), and pelvic lymph node metastases (0.65, 0.95). CONCLUSION MRI has good diagnostic performance for assessing myometrial invasion in patients with endometrial cancer, especially in patients younger than 60 years old. Dynamic contrast-enhanced MRI and diffusion weighted imaging can help improve sensitivity and specificity for detecting myometrial invasion. MRI shows high specificity for detecting cervical invasion and lymph node metastases in endometrial cancer.

Abstract
OBJECTIVE Sentinel lymph node (SLN) biopsy aims to assess lymph node status with reduced surgical morbidity. The aim of the study was to determine the accuracy and safety of SLN biopsy in the management of early cervical carcinoma using a double technique (technetium-99m (Tc-99m) nanocolloid and methylene blue dye injection). METHODS This was a 10-year study from January 2009 to January 2019 that recruited 103 consecutive women undergoing surgery for early cervical carcinoma, FIGO 2009 stage IA1 (grade 3, and grade 2 with lymphovascular space invasion) to IB1 (<2 cm), at the West Kent Gynaecological Oncology Centre, Maidstone, UK. All patients were given the choice of pelvic node dissection and SLN mapping or SLN only. All patients elected to undergo SLN only. In total 97 patients had SLN mapping performed laparoscopically. We used the combined method (Tc-99m nanocolloid and/or methylene blue dye). All SLN routinely underwent ultrastaging. RESULTS At least one SLN was detected in all 103 patients, using at least one of the combined methods (Tc-99m nanocolloid or blue dye). Bilaterally SLN were removed in 85/103 women with an 83% bilateral detection rate. The median SLN count was 2.3 (range 1-6) nodes. Of 103 patients, 7 (6.7%) patients had lymph node involvement. There were no pelvic or para-aortic lymph node recurrences with a median follow-up of 53 (range 8-120) months. The specificity and negative predictive value of a negative SLN was 100%. None of our 103 patients reported lower extremity lymphedema. CONCLUSION In carefully selected patients with early cervical carcinoma, SLN biopsy alone appears to be a safe method for lymph node assessment of women undergoing surgical staging. Ultrastaging is an essential part of histologic examination of SLN.

Abstract
OBJECTIVE The survival and prognostic factors for locally advanced cervical cancer treated with nerve-sparing Okabayashi-Kobayashi radical hysterectomy have not been elucidated. We aimed to evaluate the oncological outcomes of those patients after radical hysterectomy with adjuvant chemotherapy. METHODS This retrospective cohort study was conducted from January 2002 to December 2011. Treatment was conducted at a single tertiary center in northern Japan. We used the Okabayashi-Kobayashi radical hysterectomy with lymphadenectomy. We applied unilateral nerve preservation for stage IIA/IIB cancer if there was a one-sided extension of the disease outside the cervix. Indication for adjuvant therapy was based on Sedlis criteria. High-risk was defined as evidence of lymph node metastasis, pathological parametrial invasion, and a positive/close surgical margin. The choice of adjuvant therapy was chemotherapy which consisted of paclitaxel and cisplatin. RESULTS The study included 76 early-stage IB1 (≤4 cm) and IIA1 cervical cancer and 45 locally advanced stage IB2 (>4 cm), IIA2, and IIB disease treated consecutively. The median follow-up was 106 (range: 6-203) months. There were 18 (15%) patients with recurrence, with five of 76 in the early-stage (7%) and 13 of 45 in the locally advanced disease (29%) (P<0.001). For locally advanced cervical cancer, pT classification (P<0.001), lymph node metastasis (P=0.007), and histology (P=0.05) were associated with locoregional recurrence. The five-year locoregional recurrence rate in the locally advanced disease was 20% and 5% in the early-stage disease (P=0.01). The five-year disease-free survival in the locally advanced cervical cancer was 71% and 93% in the early-stage disease (P<0.001). The overall survival in locally advanced disease depended on the adeno-type histology and lymph node metastasis. CONCLUSION The tailored use of nerve-sparing Okabayashi-Kobayashi radical hysterectomy with adjuvant chemotherapy based on tumor histology and lymph node metastasis may be a possible option as a treatment of locally advanced cervical cancer in selected patients.

Abstract
Precision cancer surgery is a system that integrates the accurate evaluation of tumor extension and aggressiveness, precise surgical maneuvers, prognosis evaluation, and prevention of the deterioration of quality of life (QoL). In this regard, nerve-sparing radical hysterectomy has a pivotal role in the personalized treatment of cervical cancer. Various types of radical hysterectomy can be combined with the nerve-sparing procedure. The extent of parametrium and vagina/paracolpium excision and the nerve-sparing procedure are tailored to the tumor status. Advanced magnetic resonance imaging technology will improve the assessment of the local tumor extension. Validated risk factors for perineural invasion might guide selecting treatment for cervical cancer. Type IV Kobayashi (modified Okabayashi) radical hysterectomy combined with the systematic nerve-sparing procedure aims to both maximize the therapeutic effect and minimize the QoL impairment. Regarding the technical aspect, the preservation of vesical nerve fibers is essential. Selective transection of uterine nerve fibers conserves the vesical nerve fibers as an essential piece of the pelvic nervous system comprising the hypogastric nerve, pelvic splanchnic nerves, and inferior hypogastric plexus. This method is anatomically and surgically valid for adequate removal of the parametrial and vagina/paracolpium tissues while preserving the total pelvic nervous system. Local recurrence after nerve-sparing surgery might occur due to perineural invasion or inadequate separation of pelvic nerves cutting through the wrong tissue plane between the pelvic nerves and parametrium/paracolpium. Postoperative management for long-term maintenance of bladder function is as critical as preserving the pelvic nerves.

Abstract
OBJECTIVE To build and validate a CT radiomic model for pre-operatively predicting lymph node metastasis in early cervical carcinoma. METHODS AND MATERIALS A data set of 150 patients with Stage IB1 to IIA2 cervical carcinoma was retrospectively collected from the Nanfang hospital and separated into a training cohort (n = 104) and test cohort (n = 46). A total of 348 radiomic features were extracted from the delay phase of CT images. Mann-Whitney U test, recursive feature elimination, and backward elimination were used to select key radiomic features. Ridge logistics regression was used to build a radiomic model for prediction of lymph node metastasis (LNM) status by combining radiomic and clinical features. The area under the receiver operating characteristic curve (AUC) and κ test were applied to verify the model. RESULTS Two radiomic features from delay phase CT images and one clinical feature were associated with LNM status: log-sigma-2-0 mm-3D_glcm_Idn (p = 0.01937), wavelet-HL_firstorder_Median (p = 0.03592), and Stage IB (p = 0.03608). Radiomic model was built consisting of the three features, and the AUCs were 0.80 (95% confidence interval: 0.70 ~ 0.90) and 0.75 (95% confidence intervalI: 0.53 ~ 0.93) in training and test cohorts, respectively. The κ coefficient was 0.84, showing excellent consistency. CONCLUSION A non-invasive radiomic model, combining two radiomic features and a International Federation of Gynecology and Obstetrics stage, was built for prediction of LNM status in early cervical carcinoma. This model could serve as a pre-operative tool. ADVANCES IN KNOWLEDGE A noninvasive CT radiomic model, combining two radiomic features and the International Federation of Gynecology and Obstetrics stage, was built for prediction of LNM status in early cervical carcinoma.

Abstract
BACKGROUND Nodal status is the most important prognostic factor in cervical cancer. However, further risk stratification in node positive cervical cancer patients is warranted for optimal therapeutic decisions. MATERIAL AND METHODS Nodal positive patients (n = 86) were retrospectively stratified into two groups according to either number of positive nodes (>3 vs. 1-3) or lymph node ratio (LNR) (≥10 vs. <10% and >6.6 vs. ≤6.6%). Univariable log-rank tests and both univariable and adjusted multivariable Cox regression models were used to evaluate the association between number of positive nodes or LNR and disease-free survival (DFS) and overall survival (OS). RESULTS LNR was significantly associated with worse DFS in adjusted multivariable analysis, both when categorized as ≥10 versus <10% (HR 2.25, 95% CI 1.06-4.76, p = 0.034) and when categorized as >6.6 versus ≤6.6% (HR 2.79, 95% CI 1.23-6.37, p = 0.015). However, we found no significant association between number of positive nodes or LNR and OS. DISCUSSION In operable node-positive cervical cancer, both number of positive lymph nodes and LNR can be used for further risk stratification with regard to DFS but not OS.

Abstract
CONTEXT.— Ultrastaging of sentinel lymph nodes (SLNs) is a crucial aspect in the approach to SLN processing. No consensual protocol for pathologic ultrastaging has been approved by international societies to date. OBJECTIVE.— To provide a review of the ultrastaging protocol and all its aspects related to the processing of SLNs in patients with cervical cancer. DATA SOURCES.— In total, 127 publications reporting data from 9085 cases were identified in the literature. In 24% of studies, the information about SLN processing is entirely missing. No ultrastaging protocol was used in 7% of publications. When described, the differences in all aspects of SLN processing among the studies and institutions are substantial. This includes grossing of the SLN, which is not completely sliced and processed in almost 20% of studies. The reported protocols varied in all aspects of SLN processing, including the thickness of slices (range, 1-5 mm), the number of levels (range, 0-cut out until no tissue left), distance between the levels (range, 40-1000 μm), and number of sections per level (range, 1-5). CONCLUSIONS.— We found substantial differences in protocols used for SLN pathologic ultrastaging, which can impact sensitivity for detection of micrometastases and even small macrometastases. Since the involvement of pelvic lymph nodes is the most important negative prognostic factor, such profound discrepancies influence the referral of patients to adjuvant radiotherapy and could potentially cause treatment failure. It is urgent that international societies agree on a consensual protocol before SLN biopsy without pelvic lymphadenectomy is introduced into routine clinical practice.

Abstract
PURPOSE Lymph node metastases significantly worsen the prognosis in cervical carcinoma. Risk factors-pathological and patient related-could select patients at high risk for lymph node involvement. METHODS This retrospective analysis was performed by analyzing data from patients with cervical carcinoma treated between 2000 and 2017 at the Department of Obstetrics and Gynecology of the University Hospital Ulm. RESULTS In total, 261 patients with cervical carcinoma (International Federation of Gynecology and Obstetrics (FIGO) stage IA-IIB) and lymphadenectomy with at least 10 removed lymph nodes were available for analysis. Overall, 86 (33.0%) patients had lymph node metastases; 73 patients had pelvic lymph node metastases only and 13 patients had both pelvic and paraaortic lymph node metastases. Lymph node metastases were found most often in the region of the external iliac artery and obturator fossa, with 57.0% and 54.7% of all 86 node-positive patients, respectively. Univariable analyses showed that presence of lymph node metastases was significantly associated with both preoperative FIGO stage (p = 0.001) and final pathological tumor stage (p < 0.001), status of resection margin (p = 0.002), lymphovascular space invasion (LVSI), (p < 0.001) and vascular space invasion, (p < 0.001). In a multivariable logistic regression model with presence of lymph node metastases (yes/no) as binary response variable, only LVSI (p < 0.001) and body mass index (BMI), (p = 0.035) remained as significant independent predictors of lymph node involvement. Subgroup analyses showed that LVSI was a significant predictive factor for lymph node involvement in patients with a preoperatively assessed FIGO stage < IIB (p < 0.001), but not for patients with a preoperatively assessed FIGO stage ≥ IIB (p = 0.122). CONCLUSIONS The risk factor LVSI should play an important role in deciding whether an individualized therapy concept is based on escalating or deescalating treatment. In future, the sentinel concept could reduce morbidity and at the same time provide an important prognostic assessment for a subset of cervical cancer patients.

Abstract
Lymph node status is the most important prognostic factor of survival in women with early stage cervical cancer. Sentinel lymph node (SLN) biopsy is an accurate method for the assessment of lymph nodal involvement in early-stages cervical cancer and has been increasingly used instead of systematic pelvic lymph node dissection (PLND). Less-radical lymph node dissection decreases the associated morbidity of PLND, especially the risk of lower-leg lymphoedema, which affects severely patient quality of life. SLN biopsy allows nodes ultrastaging and provides supplementary histological information by increasing the detection of tumor low-volume (isolated tumors cells and micrometastases). Moreover, SLN biopsy provides accurate anatomical information on pelvic lymphatic drainage pathway by identifying nodes outside of routine lymphadenectomy areas. Selection of a population at low-risk of nodal metastasis, a minimal training, and simple rules may ensure a low false negative rate. Several studies have shown that SLN mapping in these patients is feasible, with excellent detection rates and sensitivity. Combined detection with technetium-99 and blue dye has been widely used but recently, there has been increasing interest in the use of fluorescent dies such as indocyanine green (ICG) which would improve SLN detection. Although recent international guidelines recommend performing SLN biopsy in addition to PLND, SLN biopsy alone is not the gold-standard yet due to lack of prospective evidence, especially on long-term oncological safety. Some points remain controversial such as the low accuracy of intraoperative SLN status assessment by frozen section and the impact of micrometastasis on prognostic. The prospective randomized clinical trial SENTICOL III will answer to these problematics.
