Abstract
BACKGROUND Cervical cancer is and will remain to be an important health problem in China, especially with an increasing proportion of younger patients who has more specific needs. In China, surgery to remove tumor burden followed by postoperative treatment with radiotherapy and chemotherapy based on clinicopathologic factors may be the best choice for stages IB3 and IIA2 patients. Radical hysterectomy in cervical cancer has been a classic landmark surgery in gynecology. The current trial is designed to evaluate whether there is a difference between laparoscopic RH and abdominal RH in cervical cancer (stages IB3 and IIA2) patient survival under stringent operation standards and consistent surgical oncologic principles. This paper reports the rationale, design, and implementation of the trial. METHODS/DESIGN This is an investigator-initiated, prospective, randomized, open, blinded endpoint (PROBE) controlled trial. A total of 1104 patients with stage IB3 and IIA2 cervical cancer will be enrolled over a period of 3 years. Patients are randomized (1:1) to either the laparoscopic RH or the abdominal RH group. Patients will then be followed up for at least 5 years. The primary end point will be 5-year overall survival, and secondary endpoints include 5-year progression-free survival, recurrence, and quality of life measurements. DISCUSSION The study results will provide more convincing evidence-based information for stages IB3 and IIA2 cervical cancer patients and their gynecologic cancer surgeons in their choice of surgical method. TRIAL REGISTRATION ClinicalTrials.gov, NCT04939831 , retrospectively registered on 25 June 2021.

Abstract
Cervical cancer is an aggressive type of cancer affecting women worldwide. Many affected individuals rely on smear tests for the diagnosis, surgery, chemotherapy, or radiation for their treatment. However, due to a broad set of undesired results and side-effects associated with the existing protocols, the search for better diagnostic and therapeutic interventions is a never-ending pursuit. In the purview, the bio-concentration of trace elements (copper, selenium, zinc, iron, arsenic, manganese, and cadmium) is seen to fluctuate during the occurrence of cervical cancer and its progression from pre-cancerous to metastatic nature. Thus, during the occurrence of cervical cancer, the detection of trace elements and their supplementation will prove to be highly advantageous in developing diagnostic tools and therapeutics, respectively. This review provides a detailed overview of cervical cancer, its encouragement by human papillomavirus infections, the mechanism of pathology, and resistance. Majorly, the review emphasizes the less explored role of trace elements, their contribution to the growth and inhibition of cervical cancer. Numerous clinical trials have been listed, thereby providing a comprehensive reference to the exploration of trace elements in the management of cervical cancer.

Abstract
Background A retrospective study and a randomized controlled trial published in a high quality journal in late 2018 have shown that laparoscopic radical hysterectomy (RH) was associated with worse survival than abdominal RH among patients with early stage cervical cancer. Radical hysterectomy in cervical cancer has been a classic landmark surgery in gynecology, therefore this conclusion is pivotal. The current trial is designed to reconfirm whether there is a difference between laparoscopic RH and abdominal RH in cervical cancer (stage IA1 with LVSI, IA2) patient survival under stringent operation standards and consistent tumor-free technique. This paper reports the rationale, design, and implementation of the trial. Methods This is an investigator-initiated, prospective, randomized, open, blinded endpoint (PROBE) controlled trial. A total of 690 patients with stage IA1 (with intravascular), and IA2 cervical cancer will be enrolled over a period of three years. Patients are randomized (1:1) to either the laparoscopic RH or the abdominal RH group. Patients will then be followed-up for at least five years. The primary endpoint will be 5-year progression-free survival. Secondary endpoints will include 5-year overall survival rates, recurrence rates, operation time, intraoperative blood loss, surgery-related complications, and quality of life. Discussion The results of the trial will provide valuable evidence for guiding clinical decision of choosing appropriate treatment strategies for stage IA1 (LVSI) and stage IA2 cervical cancer patients.

Abstract
Cervical Cancer is one of the leading causes of cancer-associated mortality in women. The present study aimed to identify key genes and pathways involved in cervical cancer (CC) progression, via a comprehensive bioinformatics analysis. The GSE63514 dataset from the Gene Expression Omnibus database was analyzed for hub genes and cancer progression was divided into four phases (phases I-IV). Pathway enrichment, protein-protein interaction (PPI) and pathway crosstalk analyses were performed, to identify key genes and pathways using a criterion nodal degree ≥5. Gene pathway analysis was determined by mapping the key genes into the key pathways. Co-expression between key genes and their effect on overall survival (OS) time was assessed using The Cancer Genome Atlas database. A total of 3,446 differentially expressed genes with 107 hub genes were identified within the four phases. A total of 14 key genes with 11 key pathways were obtained, following extraction of ≥5 degree nodes from the PPI and pathway crosstalk networks. Gene pathway analysis revealed that CDK1 and CCNB1 regulated the cell cycle and were activated in phase I. Notably, the following terms, 'pathways in cancer', 'focal adhesion' and the 'PI3K-Akt signaling pathway' ranked the highest in phases II-IV. Furthermore, FN1, ITGB1 and MMP9 may be associated with metastasis of tumor cells. STAT1 was indicated to predominantly function at the phase IV via cancer-associated signaling pathways, including 'pathways in cancer' and 'Toll-like receptor signaling pathway'. Survival analysis revealed that high ITGB1 and FN1 expression levels resulted in significantly worse OS. CDK1 and CCNB1 were revealed to regulate proliferation and differentiation through the cell cycle and viral tumorigenesis, while FN1 and ITGB1, which may be developed as novel prognostic factors, were co-expressed to induce metastasis via cancer-associated signaling pathways, including PI3K-Art signaling pathway, and focal adhesion in CC; however, the underlying molecular mechanisms require further research.

Abstract
BACKGROUND The aim of the current study was to re-evaluate the role of minimally invasive liver resection (MILR) among patients with early-stage (stage I or II) hepatocellular carcinoma (HCC) undergoing partial hepatectomy. METHODS A retrospective analysis of the National Cancer Database (NCDB) was conducted to identify patients with early-stage HCC who underwent partial hepatectomy in the USA from 2010 to 2013. Overall survival (OS) was compared in three cohorts: crude; stabilized inverse probability of treatment propensity score weighting (IPTW); and propensity score matching (PSM). RESULTS Among 4027 patients included in the study, only 11.7%, (n = 473) underwent MILR. In the stabilized IPTW cohort, patients who underwent MILR versus open resection were more likely to have tumors greater than 3 cm (63.9%, n = 285 vs. 51.4%, n = 228, p < 0.001) and poorly/undifferentiated tumors (21.5%, n = 96 vs. 12.9%, n = 57, p < 0.001). Within the crude cohort, a 5-year OS was superior among patients in the open surgical group (67.8%) compared with patients who underwent MILR (56.6%) (p < 0.001). After classic PSM analysis, the 5-year OS of patients undergoing MILR and open surgery were noted to be comparable (57.3% vs 63.8%, p = 0.17; HR 1.16, 95% CI 0.92-1.45). In contrast, after applying IPTW, the 5-year OS of patients who underwent MILR (55.5%) was worse compared with patients who had an open resection (67.5%) (HR 1.46, 95% CI 1.15-1.84; p < 0.001). CONCLUSIONS Long-term outcomes of patients undergoing MILR were comparable with patients who had open surgery when assessed by standard PSM. The use of IPTW resulted in more unbalanced groups leading to residual confounding and bias.

Abstract
BACKGROUND Little is known about outcomes in patients after being hospitalized for care of cancer or comorbid conditions and the disparity between African-American and White cervical cancer patients. METHODS Using the national inpatient sample (HCUP-NIS) database of the Healthcare Cost and Utilization Project between 2002-2014, we included 5217 African-American and 21,752 White patients hospitalized with a primary diagnosis of cervical cancer. We examined racial differences in hospitalization outcomes; length of stay (LOS) in hospital, mortality in hospital, post-operative complications in patients who underwent hysterectomy and discharge disposition. Patients were matched on age at primary diagnosis, insurance status, residential region, and median income of residential area, modified Deyo comorbidity index, stage of disease and treatment. Categorical outcomes were analyzed by conditional logistic regression accounting for matched study design and odds ratios (95%CI) were reported. LOS was analyzed using t-test and beta estimate for difference in means was reported. RESULTS The LOS was significantly lower for Whites compared to African-American cervical cancer patients when matched on demographic only (β=-0.41, p-value<0.0005, presentation + demographic (β=-0.41, p-value<0.0006) and treatment + presentation + demographic variables (β=-0.46, p-value<0.0001). White cervical cancer patients were commonly discharged to other intermediate nursing facility (OR = 1.30, 95%CI = 1.20-1.41, matched on demographic only; OR = 1.31, 95%CI = 1.21-1.43, matched on presentation + demographic; and OR = 1.32, 95%CI = 1.22-1.43), matched on treatment + presentation + demographic). Similar trends were seen in both older (≥65 years) and younger (<65 years) patients, when stratified by age. CONCLUSION Disparities in hospitalization outcomes in cervical patients are not observed when different characteristics of African-American and White cervical patients are accounted for and matched.

Abstract
AIMS Gastric-type endocervical adenocarcinoma (EA) is characterised by aggressive behaviour and pathogenesis independent of human papillomavirus infection. Because of its morphology and frequent mutation-pattern expression of p53, gastric-type EA may be confused with several types of endometrial carcinoma, particularly in biopsy and curettage specimens. HIK1083 and MUC6 are immunohistochemical markers used to support a diagnosis of gastric-type EA; however, the rates of expression of these markers in endometrial tumours are largely unknown. We therefore aimed to assess the expression of HIK1083 and MUC6 in a cohort of different types of endometrial carcinoma. METHODS AND RESULTS Ninety-one endometrial carcinomas (56 endometrioid, 16 clear cell, and 19 serous) from 91 patients treated with hysterectomy were included. A representative tumour block from each case was used for immunohistochemical staining with HIK1083 and MUC6. The percentage of stained cells (0-100%) and average staining intensity (weak, moderate, and strong) were recorded for both markers. None of 91 cases expressed HIK1083. In contrast, 66% (60/91) of cases showed at least focal expression of MUC6; importantly, 54 of 60 (90%) positive cases showed moderate or strong staining. Five of 60 (8%) cases showed MUC6 staining in ≥50% of tumour cells. Endometrioid tumours (49/56, 88%) were more likely to express MUC6 than cases of clear cell (1/16, 6%) or serous (10/19, 53%) carcinoma. DISCUSSION Endometrial carcinoma often expresses MUC6. In contrast, HIK1083 is consistently negative, and thus, when positive, is a more reliable marker for distinguishing gastric-type EA from some of its endometrial mimics.

BACKGROUND Minimally invasive surgery was adopted as an alternative to laparotomy (open surgery) for radical hysterectomy in patients with early-stage cervical cancer before high-quality evidence regarding its effect on survival was available. We sought to determine the effect of minimally invasive surgery on all-cause mortality among women undergoing radical hysterectomy for cervical cancer. METHODS We performed a cohort study involving women who underwent radical hysterectomy for stage IA2 or IB1 cervical cancer during the 2010-2013 period at Commission on Cancer-accredited hospitals in the United States. The study used inverse probability of treatment propensity-score weighting. We also conducted an interrupted time-series analysis involving women who underwent radical hysterectomy for cervical cancer during the 2000-2010 period, using the Surveillance, Epidemiology, and End Results program database. RESULTS In the primary analysis, 1225 of 2461 women (49.8%) underwent minimally invasive surgery. Women treated with minimally invasive surgery were more often white, privately insured, and from ZIP Codes with higher socioeconomic status, had smaller, lower-grade tumors, and were more likely to have received a diagnosis later in the study period than women who underwent open surgery. Over a median follow-up of 45 months, the 4-year mortality was 9.1% among women who underwent minimally invasive surgery and 5.3% among those who underwent open surgery (hazard ratio, 1.65; 95% confidence interval [CI], 1.22 to 2.22; P=0.002 by the log-rank test). Before the adoption of minimally invasive radical hysterectomy (i.e., in the 2000-2006 period), the 4-year relative survival rate among women who underwent radical hysterectomy for cervical cancer remained stable (annual percentage change, 0.3%; 95% CI, -0.1 to 0.6). The adoption of minimally invasive surgery coincided with a decline in the 4-year relative survival rate of 0.8% (95% CI, 0.3 to 1.4) per year after 2006 (P=0.01 for change of trend). CONCLUSIONS In an epidemiologic study, minimally invasive radical hysterectomy was associated with shorter overall survival than open surgery among women with stage IA2 or IB1 cervical carcinoma.

Bauhinia variegata candida Fraction Induces Tumor Cell Death by Activation of Caspase-3, RIP, and TNF-R1 and Inhibits Cell Migration and Invasion In Vitro. BIOMED RESEARCH INTERNATIONAL 2018; 2018:4702481.

Abstract
Metastasis remains the most common cause of death in cancer patients. Inhibition of metalloproteinases (MMPs) is an interesting approach to cancer therapy because of their role in the degradation of extracellular matrix (ECM), cell-cell, and cell-ECM interactions, modulating key events in cell migration and invasion. Herein, we show the cytotoxic and antimetastatic effects of the third fraction (FR3) from Bauhinia variegata candida (Bvc) stem on human cervical tumor cells (HeLa) and human peripheral blood mononuclear cells (PBMCs). FR3 inhibited MMP-2 and MMP-9 activity, indicated by zymogram. This fraction was cytotoxic to HeLa cells and noncytotoxic to PBMCs and decreased HeLa cell migration and invasion. FR3 is believed to stimulate extrinsic apoptosis together with necroptosis, assessed by western blotting. FR3 inhibited MMP-2 activity in the HeLa supernatant, differently from the control. The atomic mass spectrometry (ESI-MS) characterization suggested the presence of glucopyranosides, D-pinitol, fatty acids, and phenolic acid. These findings provide insight suggesting that FR3 contains components with potential tumor-selective cytotoxic action in addition to the action on the migration of tumor cells, which may be due to inhibition of MMPs.

Abstract
Background Most cervical cancer patients worldwide receive surgical treatments, and yet the current International Federation of Gynecology and Obstetrics (FIGO) staging system do not consider surgical-pathologic data. We propose a more comprehensive and prognostically valuable surgical-pathologic staging and scoring system (SPSs). Methods Records from 4,220 eligible cervical cancer cases (Cohort 1) were screened for surgical-pathologic risk factors. We constructed a surgical-pathologic staging and SPSs, which was subsequently validated in a prospective study of 1,104 cervical cancer patients (Cohort 2). Results In Cohort 1, seven independent risk factors were associated with patient outcome: lymph node metastasis (LNM), parametrial involvement, histological type, grade, tumor size, stromal invasion, and lymph-vascular space invasion (LVSI). The FIGO staging system was revised and expanded into a surgical-pathologic staging system by including additional criteria of LNM, stromal invasion, and LVSI. LNM was subdivided into three categories based on number and location of metastases. Inclusion of all seven prognostic risk factors improves practical applicability. Patients were stratified into three SPSs risk categories: zero-, low-, and high-score with scores of 0, 1 to 3, and ≥4 (P=1.08E-45; P=6.15E-55). In Cohort 2, 5-year overall survival (OS) and disease-free survival (DFS) outcomes decreased with increased SPSs scores (P=9.04E-15; P=3.23E-16), validating the approach. Surgical-pathologic staging and SPSs show greater homogeneity and discriminatory utility than FIGO staging. Conclusions Surgical-pathologic staging and SPSs improve characterization of tumor severity and disease invasion, which may more accurately predict outcome and guide postoperative therapy.

Abstract
Of gynecological cancers, cervical cancer has the second highest incidence globally and is a major cause of cancer‑associated mortality in women. An increasing number of studies have reported that microRNAs (miRNAs) have important roles in cervical cancer carcinogenesis and progression through regulation of various critical protein‑coding genes. The aim of the present study was to investigate the expression and biological roles of miRNA‑211 (miR‑211) in cervical cancer and its underlying molecular mechanism. The results of reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR) demonstrated that the expression levels of miR‑211 in cervical cancer tissues and cell lines were significantly lower compared with adjacent normal tissues and the normal human cervix epithelial cell line, respectively. Furthermore, upregulation of miR‑211 by transfection with miR‑211 mimics inhibited cell proliferation, migration and invasion of cervical cancer, as determined by MTT, Transwell and Matrigel assays, respectively. Bioinformatics analysis and luciferase reporter assay results indicated that zinc finger E‑box binding homeobox 1 (ZEB1) may be a direct target gene of miR‑211. In addition, RT‑qPCR and western blot analysis results demonstrated that miR‑211 overexpression markedly reduced ZEB1 expression at mRNA and protein levels in cervical cancer. Furthermore, the effects of ZEB1 downregulation on the proliferation, migration and invasion of cervical cancer cells were similar to those induced by miR‑211 overexpression. These results indicate that miR‑211 may act as a tumor suppressor in cervical cancer by directly targeting ZEB1. Therefore, miR‑211/ZEB1‑based targeted therapy may represent a potential novel treatment for patients with cervical cancer.

Jacob L, Kalder M, Kostev K. Incidence of depression and anxiety among women newly diagnosed with breast or genital organ cancer in Germany. Psychooncology 2017; 26:1535-1540. [PMID: 27897353 DOI: 10.1002/pon.4328] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2016] [Revised: 11/17/2016] [Accepted: 11/22/2016] [Indexed: 12/12/2022]
Abstract
BACKGROUND To analyze the incidence of depression and anxiety among women newly diagnosed with breast or genital organ cancer (BC or GOC) in Germany. METHODS A total of 29 366 women initially diagnosed with BC or GOC between 2005 and 2014 were available for analysis. The main outcome measure was the incidence of depression and anxiety among women newly diagnosed with BC or GOC within 5 years after the first cancer diagnosis in German gynecologist practices. Demographic and clinical data included age, type of cancer, and presence of metastases at diagnosis. The incidence rate of depression and anxiety per 100 person-years was calculated. We performed a multivariate regression model to analyze the association between depression and the variables of interest. RESULTS In total, 7994 women were diagnosed with depression/anxiety (81.3% had BC and 18.7% had GOC). The incidence of depression and anxiety was 8.8 per 100 person-years in women with BC. In individuals with GOC, the incidence of depression/anxiety was 5.9 per 100 person-years. Breast cancer was associated with a 1.41-fold increase in the risk of developing depression or anxiety as compared with GOC. Patients with metastases also had a higher risk of being depressed and anxious than others (odds ratio = 1.40). Finally, women in the age groups of 41 to 50, 51 to 60, and 61 to 70 years were at a higher risk of depression/anxiety than women in the age group of 71 to 80 years (odds ratios equal to 1.50, 1.38, and 1.22). CONCLUSIONS Women diagnosed with BC were at a higher risk of developing depression or anxiety than women with GOC.

Abstract
The synthetic compound 7-4-[Bis-(2-hydroxyethyl)-amino]-butoxy-5-hydroxy-8-methoxy-2-phenylchromen-4-one (V8) is a novel flavonoid-derived compound. In this study, we investigated the effects of V8 on Toll-like receptor 4 (TLR4)-mediated inflammatory reaction in human cervical cancer SiHa cells and lipopolysaccharide (LPS)-induced TLR4 activity in cervical cancer SiHa (HPV16+) cells, but not in HeLa (HPV18+) and C33A (HPV-) cells. In addition, V8 inhibited LPS-induced expression of TLR4, MyD88, TRAF6 and phosphorylation of TAK1, and their interaction with TLR4 in SiHa cells, resulting in an inhibition of TLR4-MyD88-TRAF6-TAK1 complex. Moreover, V8 blocked LPS-induced phosphorylation of IκB and IKK, resulting in inhibition of the nuclear translocation of P65-NF-κB in SiHa cells. We also found that V8 reduced the expression of NF-κB target genes, such as those for COX-2, iNOS, IL-6, IL-8, CCL-2, and TNF-α in LPS-stimulated SiHa cells. These results suggested that V8 exerted an anti-inflammatory effect on SiHa cells by inhibiting the TLR4-MyD88-TRAF6-TAK1 complex-mediated NF-κB activation.

Abstract
Although a rare cancer in the developed world due to the success of cervical screening programmes, cervical cancer remains one of the most common cancers diagnosed in women under the age of 35 years old. Radical hysterectomy and more recently radical trachelectomy have been highly effective in curing the majority of women with early stage disease. Many, however, are left with long-term 'survivorship' issues including bowel, bladder and sexual dysfunction. In view of these chronic co-morbidities, many clinicians now consider whether a less radical approach to surgery may be an option for some women. This review focuses on the current evidence for the safety of conservative surgery for early stage cervical cancer with regard to cure rates in comparison to standard management, as well as any improvement in short and long-term morbidity associated with a more conservative approach.

Abstract
Cervical cancer is the most common gynecological cancer in Brazil. Among women, it is the second most frequent, second only to breast cancer. It is the fourth leading cause of cancer death in the country, with estimated 15,590 new cases (2014) and 5,430 deaths (2013). In order to update information to improve outcomes, reduce morbidity and optimize the treatment of this cancer, this article will address the advancement of knowledge on cervical cancer. The topics covered include the role of surgery in different stages, treatment of locally advanced carcinomas, fertility preservation, the role of the sentinel lymph node technique, indications and techniques of radiotherapy and chemotherapy, and some special situations.

Abstract
BACKGROUND Women living in Africa experience the highest burden of cervical cancer. Research and investment to improve vaccination, screening, and treatment efforts are critically needed. We systematically reviewed and characterized recent research within a broader public health framework to organize and assess the range of cervical cancer research in Africa. METHODS We searched online databases and the Internet for published articles and cervical cancer reports in African countries. Inclusion criteria included publication between 2004 and 2014, cervical cancer-related content pertinent to one of the four public health categories (primary, secondary, tertiary prevention or quality of life), and conducted in or specifically relevant to countries or regions within the African continent. The study design, geographic region/country, focus of research, and key findings were documented for each eligible article and summarized to illustrate the weight and research coverage in each area. Publications with more than one focus (e.g. secondary and tertiary prevention) were categorized by the primary emphasis of the paper. Research specific to HIV-infected women or focused on feasibility issues was delineated within each of the four public health categories. RESULTS A total of 380 research articles/reports were included. The majority (54.6 %) of cervical cancer research in Africa focused on secondary prevention (i.e., screening). The number of publication focusing on primary prevention (23.4 %), particularly HPV vaccination, increased significantly in the past decade. Research regarding the treatment of precancerous lesions and invasive cervical cancer is emerging (17.6 %), but infrastructure and feasibility challenges in many countries have impeded efforts to provide and evaluate treatment. Studies assessing aspects of quality of life among women living with cervical cancer are severely limited (4.1 %). Across all categories, 11.3 % of publications focused on cervical cancer among HIV-infected women, while 17.1 % focused on aspects of feasibility for cervical cancer control efforts. CONCLUSIONS Cervical cancer research in African countries has increased steadily over the past decade, but more is needed. Tertiary prevention (i.e. treatment of disease with effective medicine) and quality of life of cervical cancer survivors are two severely under-researched areas. Similarly, there are several countries in Africa with little to no research ever conducted on cervical cancer.

Abstract
The present study aimed to investigate the inhibitory ability of β-hydroxyisovaleryl-shikonin (β-HIVS) on the proliferation of human cervical cancer HeLa cells and to identify the mechanism of this effect. The HeLa cells were treated with β-HIVS and the inhibition of cell growth was detected by an MTT assay. Flow cytometry was performed to analyze the apoptosis rate and cell cycle distribution of HeLa cells. Reverse transcription-polymerase chain reaction and western blot analysis were used to examine the expression of the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR) signaling pathway proteins. The results revealed that β-HIVS inhibited HeLa cell proliferation in a dose- and time-dependent manner. With the administration of increasing concentrations of β-HIVS, the apoptotic rate of HeLa cells was also increased. The cell cycle was slightly arrested at the S phase, with ~6% of cells in this phase, subsequent to treatment with 10 µM β-HIVS. In addition, β-HIVS markedly reduced the expression levels of PI3K, AKT, mTOR and 70-kDa ribosomal protein S6 kinase in HeLa cells. β-HIVS promoted cervical cancer cell apoptosis by inhibiting the PI3K/AKT/mTOR signaling pathway and suppressing downstream gene expression. The present study is expected to lead to the development of molecular targeted therapy for this signaling pathway as a novel method of cervical cancer treatment.

Gynecol Oncol 2015; 138:478-85. [PMID: 26047592 DOI: 10.1016/j.ygyno.2015.05.039] [Citation(s) in RCA: 106] [Impact Index Per Article: 11.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2015] [Revised: 05/29/2015] [Accepted: 05/29/2015] [Indexed: 11/25/2022]
Abstract
OBJECTIVES Sentinel lymph node (SLN) procedure could be an attractive solution to the debate on lymphadenectomy in endometrial cancer; however challenges to interpreting the literature include marked heterogeneity across studies, a wide variety of injection techniques and a lack of uniformly accepted definitions for important outcomes. We aim to critically appraise the published literature and streamline terminology and methodology for future studies in this field. METHODS We conducted a PubMed search and included all original research of endometrial cancer patients having undergone SLN procedure with an n>30. Data collected included injection technique, unilateral, bilateral, and para-aortic detection rates, and ultrastaging results. When different definitions were used for reporting outcomes, we recalculated the original study results according to our proposed definitions. Data was analyzed using descriptive statistics. RESULTS Seventeen studies met our inclusion criteria. Injection sites were categorized into cervical versus corporeal. Overall detection rates ranged from 60 to 100%; studies with n>100 all had overall detection rates of >80%. Bilateral detection rates were higher with a combination of two injection agents. Para-aortic mapping was most frequent after corporeal injection techniques (39%), and was higher after deep vs. standard cervical injection (17% vs. 2%). The proportion of metastatic lymph nodes diagnosed through ultrastaging was high (around 40%) and ultrastaging of SLN upstaged approximately 5% of patients. Retrospectively applying a surgical algorithm revealed a sensitivity of 95%, a negative predictive value of 99%, and a false negative rate of 5% (with only 9 false negative cases remaining in total). CONCLUSION Results of SLN research for endometrial cancer are promising. We believe that in future studies, uniform reporting is needed to improve our understanding of the safety and feasibility of SLN in EC. We propose 2 strategies: a checklist of elements to include in future reports and the standardization of key definitions.
