Cost-effectiveness analysis of simple hysterectomy compared to radical hysterectomy for early cervical cancer: analysis from the GCIG/CCTG CX.5/SHAPE trial.

SHAPE (Simple Hysterectomy And PElvic node assessment) was an international phase III trial demonstrating that simple hysterectomy was non-inferior to radical hysterectomy for pelvic recurrence risk, but superior for quality of life and sexual health. The objective was to conduct a cost-effectiveness analysis comparing simple vs. radical hysterectomy for low-risk early-stage cervical cancer. Markov model compared the costs and benefits of simple vs. radical hysterectomy for early cervical cancer over a 5-year time horizon. Quality-adjusted life years (QALYs) were estimated from health utilities derived from EQ-5D-3L surveys. Sensitivity analyses accounted for uncertainty around key parameters. Monte Carlo simulation estimated complication numbers according to surgical procedure. Simple hysterectomy was more effective and less costly than radical hysterectomy. Average overall costs were $11,022 and $12,533, and average gains were 3.56 and 3.54 QALYs for simple and radical hysterectomy, respectively. Baseline health utility scores were 0.81 and 0.83 for simple and radical hysterectomy, respectively. By year 3, these scores improved for simple hysterectomy (0.82) but not for radical hysterectomy (0.82). Assuming 800 early cervical cancer patients annually in Canada, the model estimated 3 vs. 82 patients with urinary retention, and 49 vs. 86 patients with urinary incontinence persisting 4 weeks after simple vs. radical hysterectomy, respectively. Results were most sensitive to variability in health utilities after surgery, but stable through wide ranges of costs and recurrence estimates. Simple hysterectomy is less costly and more effective in terms of quality-adjusted life expectancy compared to radical hysterectomy for early cervical cancer.

Roles of microRNA-486-5p in the diagnosis and the association with clinical symptoms of cervical cancer.

Aim: To explore the predictive value of miR-486-5p in early cervical cancer and the associations of miR-486-5p with different clinical symptoms.Materials & methods: A total of 185 women were recruited. The relative expression levels of serum miR-486-5p were analyzed by real-time polymerase chain reaction. The receiver operator characteristic curves were utilized to reflect the predictive performance of miR-486-5p and squamous cell carcinoma antigen for early cervical cancer. Univariate logistic regression and ranked logistic regression were used to explore the associations of miR-486-5p with different clinical symptoms of early cervical cancer, with odd ratios (ORs) and 95% confidence intervals.Results: Eighty-one women (44.26%) had early cervical cancer. The relative expression of serum miR-486-5p was 1.99-fold higher in early cervical cancer patients than that in controls (p<0.0001). The predictive performance of miR-486-5p for early cervical cancer was significantly superior to that of squamous cell carcinoma antigen, with an area under the curve of 0.865 (p<0.001), sensitivity of 1.000and specificity of 0.804. In addition, overexpressed miR-486-5p was associated with high odds of maximum tumor diameter increase (OR=1.30, 95%CI: [1.01-1.66]).Conclusion: MiR-486-5p may be a potential biomarker for the early cervical cancer diagnosis, and was linked to the risk of maximum tumor diameter.

High keratin 15 expression reflects favorable prognosis in early cervical cancer patients.

Keratin 15 (KRT15) exhibits inconsistent prognostic roles in different cancers, and its prognostic value in early cervical cancer patients who receive tumor resection remains unknown. This study aimed to assess the relationship of KRT15 expression with prognosis in these patients. Totally, 147 early cervical cancer patients who received tumor resection were reviewed in this retrospective study. KRT15 was detected in formalin-fixed paraffin-embedded tumor tissue by immunohistochemistry (IHC). KRT15 IHC scores were computed by multiplying the percentage of positively stained cells (scored as 0-4) and corresponding staining intensity (scored as 0-3), ranging from 0 to 12. Elevated KRT15 IHC score was linked with moderate to well differentiation (P = 0.005), tumor size ≤ 4cm (P = 0.017), and International Federation of Gynecology and Obstetrics (FIGO) stage Ia/Ib (P < 0.001). KRT15 IHC score was inversely associated with adjuvant radiotherapy (P = 0.025) and adjuvant chemotherapy (P = 0.016). KRT15 IHC score ≥ 1 was linked with increased disease-free survival (DFS) (P = 0.003) and overall survival (OS) (P = 0.049). Meanwhile, KRT15 IHC score ≥ 1 independently predicted increased DFS (hazard ratio = 0.213, P = 0.017), but not OS (P > 0.05). KRT15 IHC score ≥ 3 and KRT15 IHC score ≥ 6 could not predict DFS or OS (all P > 0.05). By subgroup analyses, KRT15 IHC score ≥ 1 forecasted favorable DFS in patients with age > 45years, human papillomavirus-positive, squamous carcinoma, and tumor size ≤ 4cm (all P < 0.05). KRT15 IHC score ≥ 1 and KRT15 IHC score ≥ 3 predicted ascended DFS in patients without adjuvant radiotherapy or adjuvant chemotherapy (all P < 0.05). High KRT15 expression reflects favorable tumor features and longer survival in early cervical cancer patients who receive tumor resection.

Ameliyat edilebilir Rahim Ağzı Kanserinde Hematolojik İnflamatuar Belirteçler ile Genel Özellikler Arasındaki İlişki; HALP indeksinin yeri.

Background: Cervical cancer is the most common gynecologic malignancy and the leading cause of cancer-related mortality in women worldwide. Systemic inflammatory reactions in cancer patients impact nutrition, function, and prognosis. Poor nutritional health is linked to a worse prognosis in several malignancies. A new score called the hemoglobin-albumin-lymphocyte-platelet (HALP) index was developed using dietary and inflammatory deficiencies.&#x0D; Method: This retrospective study and CC patients diagnosed from January 2012 to December 2020 who were operated for cervical cancer. Pre-treatment hemoglobin (Hb), albumin (Alb), lymphocyte count (Lc), and platelet (Plt) measurements were made for laboratory research.&#x0D; Results: This retrospective study revealed 74 non-metastatic cervical cancer (median age was 55, ranging from 30 to 86 years). According to the FIGO stage, the percentage of stages 1 and 2 were 78% (58 patients), and 22% (16 patients). Neutrophil lymphocyte ratio (NLR) and platelet lymphocyte ratio (PLR), and HALP index were analyzed with LVSI, parametrial invasion, tumor size, histologic type, and duration of hospital stay; we could not find any significant correlation between the analysis. &#x0D; Conclusion: NLR, PLR, and HALP index have no prognostic value in early operable cervical cancer patients regarding the pathologic features. Prospective multicenter and more patient studies will clarify how the hematologic parameters affect oncologic outcomes.

Morbidity of adjuvant treatment in early cervical cancer: a retrospective cohort study in a Latin American center.

Radical hysterectomy with pelvic lymph node assessment is the standard of treatment in early cervical cancer. Adjuvant radiotherapy or chemoradiotherapy are offered to patients with risk factors for recurrence. The objective of this study was to compare the incidence of severe (> G3) early or late morbidity related to treatment in patients with cervical cancer undergoing radical surgery with/without adjuvant treatment in a Latin American center. Retrospective cohort study of patients diagnosed with cervical cancer stage IA1 to IB1. Complications were evaluated according to Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. The cumulative incidence of severe morbidity was estimated. Risk ratios (RR) were calculated to determine the factors associated with morbidity. 239 patients were included. 133 (55.6%) received only radical surgical management and 106 (44.4%) adjuvant treatment. The incidence of early morbidity was 18.8% [95% confidence interval (CI): 12.6% to 26.5%] in the group without adjuvant treatment versus 21.7% (95% CI: 14.3% to 30.8%) in the adjuvant treatment group (p = 0.58). Late morbidity was 3% (95% CI: 1% to 7.5%) and 8.5% (95% CI: 4% to 15.5%), respectively (p = 0.063). No statistically significant differences regarding grade ≥ 3 morbidity between the groups was found (2.3% vs. 5.7%, p = 0.289). Complications during surgery is the only factor associated with postoperative morbidity related to treatment (RR = 4.1) (95% CI: 3% to 5.7%). In our study, the addition of adjuvant treatment for early cervical cancer patients who underwent radical surgery did not increase the incidence of severe early or late morbidity.

Increasing trends of cervical conization with lymph node evaluation for fertility-sparing surgery in early cervical cancer

ObjectiveTo examine uptake, characteristics, and survival outcome of less-radical fertility-sparing surgery with cervical conization and lymph node evaluation (Cone-LN) in reproductive age patients with early cervical cancer. MethodsThis retrospective cohort study examined the National Cancer Institute's Surveillance, Epidemiology, and End Results Program. The study population included 407 patients aged <50 years with stage IA-IB2 (≤4 cm) cervical cancer who received fertility-sparing surgery from 2004 to 2019. The exposure was fertility-sparing surgery type: Cone-LN (n = 196) or trachelectomy with lymph node evaluation (Trach-LN, n = 211). The main co-outcomes were (i) temporal trends of surgery type, assessed with Cochran-Armitage test, and (ii) clinical and tumor characteristics, assessed with multivariable binary logistic regression model. The secondary outcome was overall survival, assessed with inverse probability of treatment weighting propensity score. ResultsThe number of patients receiving Cone-LN increased from 43.5% in 2004–2007 to 58.4% in 2016–2019 (P-trend = 0.005). Patients receiving conization and sentinel lymph node (SLN) biopsy alone increased from 0% to 14.4% (P-trend < 0.001). In a multivariable analysis, patients in the Cone-LN group were more likely to undergo SLN biopsy (aOR 6.04) compared to those in the Trach-LN group whereas those with adenocarcinoma (aOR 0.49) and T1b tumors (aOR for ≤2 cm 0.21, and aOR for 2.1–4.0 cm 0.10) were less likely to receive Cone-LN. In a propensity score-weighted model, the Cone-LN and Trach-LN groups had comparable overall survival (7-year rates, 98.9% vs 97.8%). Similar associations were observed for patients with squamous, adenocarcinoma / adenosquamous, T1a classification, and T1b(≤2 cm) classification. ConclusionThe current population-based analysis suggests that the performance of cervical conization with lymph node evaluation, particularly with SLN biopsy, is gradually increasing for early cervical cancer patients desiring future fertility.

TRANSLACOL project: Nodal human papillomavirus tumoral DNA detection by ddPCR for survival prediction in early cervical cancer patients without pelvic lymph node invasion

In early cervical cancer (EEC), 10 to 15% of patients without nodal metastasis (N-) will suffer from recurrences with further similar survival as N+ patients. However, no clinical, imaging or pathological risk-factor is today available to identify them. In the present study, we hypothesized that the N- histologically characterized patients who present a poor prognosis could be patients for whom metastasis are missed by classical procedure. Therefore, we propose to research HPV tumoral DNA (HPVtDNA) in pelvic Sentinel Lymph Nodes (SLN) biopsy using ultrasensitive droplet-based digital PCR (ddPCR) to detect eventual occult metastasis. Sixty HPV16, HPV18 or HPV33 positive EEC N- patients with available SLN were included. In SLN, HPV16 E6, HPV18 E7 and HPV33 E6 gene were respectively detected using ultrasensitive ddPCR technology. Survival data were analysed using Kaplan-Meier-curves and log-rank-test to compare progression-free survival (PFS) and disease-specific survival (DSS) in two groups according to their HPVtDNA status in SLN. More than half (51.7%) of the patients finally showed HPVtDNA positivity in SLN initially diagnosed as negative by histology. Two patients with negative HPVtDNA SLN and 6 with positive HPVtDNA SLN group presented recurrence. Finally, all of the 4 deaths listed in our study occurred in the positive HPVtDNA SLN group. These observations hint that the use of ultrasensitive ddPCR to detect HPVtDNA in SLN could allow the identification of two subgroups of histologically N- patients that may have different prognosis and outcome. To our knowledge, our study is the first one to evaluate the detection of HPVtDNA in SLN in early cervical cancer using ddPCR highlighting its interest as a complementary tool for N- specific early cervical cancer diagnosis.

The efficiency of ultrasound-guided erector spinae plane block in early cervical cancer patients undergoing laparotomic radical hysterectomy: A double-blind randomized controlled trial.

We aim to compare the efficiency of erector spinae plane block (ESPB) with transversus abdominis plane block (TAPB) in patients undergoing laparotomic radical hysterectomy because only a few studies are reported exploring this matter. In this randomized controlled trail, 154 eligible patients were randomly allocated into ESPB group [ESPB + patient-controlled intravenous analgesia (PCIA)] and TAPB group (TAPB + PCIA) at 1:1 ratio. The primary outcome was visual analog scale (VAS) score at rest state at 12 h. We found that ESPB group was associated with the lower VAS scores at rest and cough state than TAPB group at 2, 4, 6, 12, and 24 h postoperatively (P < 0.05). Less analgesic consumption and sufentanil consumption in PCIA pump were found in the ESPB group (P < 0.05). Moreover, ESPB group was followed by fewer rescue analgesia requirements, less rescue analgesic consumption, less adverse reactions, and higher analgesia satisfaction (P < 0.05). Our study found that ESPB had advantages on analgesic effect and opioids consumption. In the future, more studies were needed to confirm our findings.

Comparación de los resultados oncológicos entre cirugía radical por laparotomía versus la de mínima invasión en cáncer temprano de cérvix

Introduction: radical hysterectomy with pelvic lymphadenectomy is the standard treatment for early cervical cancer patients who do not wish to preserve fertility. The main objective of this study is to compare overall survival, disease-free survival, and recurrence rates of patients undergoing minimally invasive radical hysterectomy (MIS) versus open surgery. Likewise, the histopathological characteristics, intraoperative complications, early and late postoperative complications, are analyzed for both techniques, Methodology: an observational retrospective cohort study between 2011 and 2017. Patients over 18 years of age diagnosed with cervical carcinoma in stages IA1 (lymph vascular space invasion) and IB1 (FIGO 2009) receiving follow-up care until December 2020, were included. The Chi-square test, Fisher´s exact test or Mann Whitney U test were used for bivariate analysis, to determine the differences between the techniques with regards to sociodemographic, clinical characteristics and intraoperative early and late complications. Overall survival rates and recurrence densities were calculated with data provided by the patients. Results: of the 113 patients undergoing radical hysterectomy, 75 were excluded from the analysis. Overall survival was 100% in the laparotomy group versus 97.6% in the MIS group. The overall recurrence rate was of 8 cases, 14.1 per 1.000 person-years of observation in the MIS group. Patients in the laparotomy group developed no recurrences. There was a significant difference in median intraoperative blood loss (600 cc in laparotomy versus 100 cc in laparoscopy, p= 0.002); 11.4% of patients required intraoperative transfusion (25% in the laparotomy group versus 2.4% in the MIS group, p=0.006). Conclusions: patients who underwent laparoscopic surgery had a higher recurrence and mortality rate than that of open approach.

Utility of Whole Body 18F-FDG PET/CT in Comparison to Pelvic MRI in Evaluation of Local Staging of Early-Stage Carcinoma Cervix.

This prospective comparative study aimed to investigate the applied value of whole body 2-deoxy-2[fluorine-18]fluoro- D-glucose positron emission tomography integrated with computed tomography (18F-FDG PET/CT) in comparison to pelvic magnetic resonance imaging (MRI) in early cervical cancer patients. A prospective study was performed on 47 clinically early-stage cervical cancer patients evaluated with positron emission tomography/computed tomography (PET/CT) and MRI before surgery. The final postoperative histopathology report served as the reference standard. Both PET/CT and MRI images were analyzed and correlated with histopathologic findings concerning parametrial and lymph node involvement. Sensitivity, specificity, and negative predictive value (NPV) of PET/CT were 33.3%, 81.8%, and 94.7%, respectively, for parametrium assessment. And the corresponding values of pelvic MRI were 33.3%, 63.6%, and 93.3%, respectively (PET/CT versus MRI, p > 0.05). The positive predictive value (PPV) of PET/CT (11.1%) was higher than MRI (5.9%) for parametrial assessment (p < 0.05). The sensitivity, specificity, PPV, and NPV of PET/CT were 75%, 83.7%, 30%, and 97.3%, respectively, for lymph node assessment. And the corresponding values of MRI were 75%, 81.3%, 27.3%, and 97.2%, respectively (PET/CT versus MRI, p > 0.05). There was no significant difference between MRI and PET/CT concerning stage migration (p= 0.4276). The PET/CT had no additional utility (compared to MRI) in the evaluation of local staging of clinically early cervical carcinoma patients.

Open versus minimally invasive radical hysterectomy for early cervical cancer: A two-center retrospective cohort study with pathologic review of usual-type adenocarcinoma and adenosquamous carcinoma

ObjectiveTo compare survival outcomes of minimally invasive surgery (MIS) and open surgery for radical hysterectomy (RH) in early cervical cancer patients with histologic subtypes of usual-type adenocarcinoma and adenosquamous carcinoma. MethodsFrom two centers' cervical cancer cohorts, patients with 2009 FIGO stage IB1–IB2 who underwent RH between 2007 and 2020 were retrospectively identified. Patients with usual-type adenocarcinoma and adenosquamous carcinoma were included in the analysis after pathologic review according to the updated World Health Organization Classification of Tumors. Clinicopathologic characteristics and survival outcomes were compared in terms of open surgery or MIS. ResultsThis study included 161 patients. No significant differences were noted in overall survival (OS; P = 0.241) and disease-free survival (DFS; P = 0.156) between patients with usual-type adenocarcinoma (n = 136) and those with adenosquamous carcinoma (n = 25). MIS RH group (n = 99) had a significantly smaller tumor size (P < 0.001), lesser pathologic parametrial invasion (P = 0.001), and lesser lymph node metastasis (P < 0.001) than open RH group (n = 62). MIS and open RH groups showed similar OS (P = 0.201) and 3-year DFS rate (87.9% vs. 75.1%; P = 0.184). In multivariate analysis, worse DFS was not associated with MIS (P = 0.589) but was associated with pathologic parametrial invasion (adjusted HR, 3.41; 95% CI, 1.25–9.29; P = 0.016). Consistent results were observed among patients with usual-type adenocarcinoma; MIS was not associated with worse DFS. ConclusionsComparable survival outcomes were found for MIS and open RH in early-stage cervical usual-type adenocarcinoma and adenosquamous carcinoma. Although MIS RH was not a poor prognostic factor, pathologic parametrial invasion was significantly associated with worse DFS in cervical usual-type adenocarcinoma and adenosquamous carcinoma.

Comparison of the Oncological Outcomes Between Robot-Assisted and Abdominal Radical Hysterectomy for Cervical Cancer Based on the New FIGO 2018 Staging System: A Multicentre Retrospective Study.

ObjectiveTo compare the 3-year oncological outcomes of robot-assisted radical hysterectomy (RRH) and abdominal radical hysterectomy (ARH) for cervical cancer.MethodsBased on the clinical diagnosis and treatment for cervical cancer in the China database, patients with FIGO 2018 stage IA with lymphovascular space invasion (LVSI)-IB2 cervical cancer disease who underwent RRH and ARH from 2004 to 2018 were included. Kaplan–Meier survival analysis was used to compare the 3-year overall survival (OS) and disease-free survival (DFS) rate between patients receiving RRH and those receiving ARH. The Cox proportional hazards model and propensity score matching were used to estimate the surgical approach-specific survival.ResultsA total of 1,137 patients with cervical cancer were enrolled in this study, including the RRH group (n = 468) and the ARH group (n = 669). The median follow-up time was 45 months (RRH group vs. ARH group: 24 vs. 60 months). Among the overall study population, there was no significant difference in 3-year OS and DFS between the RRH group and the ARH group (OS: 95.8% vs. 97.6% p = 0.244). The Cox proportional hazards analysis showed that RRH was not an independent risk factor for 3-year OS (HR: 1.394, 95% CI: 0.552–3.523, p = 0.482). However, RRH was an independent risk factor for 3-year DFS (HR: 1.985, 95% CI: 1.078–3.655 p = 0.028). After 1:1 propensity score matching, there was no significant difference in 3-year OS between the RRH group and the ARH group (96.6% vs. 98.0%, p = 0.470); however, the 3-year DFS of the RRH group was lower than that of the ARH group (91.0% vs. 96.1%, p = 0.025). The Cox proportional hazards analysis revealed that RRH was not an independent risk factor for 3-year OS (HR: 1.622, 95% CI: 0.449–5.860 p = 0.461), but RRH was an independent risk factor for 3-year DFS (HR: 2.498, 95% CI: 1.123–5.557 p = 0.025).ConclusionAmong patients with stage I A1 (LVSI +)-I B2 cervical cancer based on the FIGO 2018 staging system, RRH has a lower 3-year DFS than ARH, suggesting that RRH may not be suitable for early cervical cancer patients.

Fertility-Sparing Surgery versus Radical Hysterectomy in Early Cervical Cancer: A Propensity Score Matching Analysis and Noninferiority Study.

Objective: Fertility-sparing surgery (FSS) is the treatment of choice for patients with early cervical cancer (ECC) and fertility desire, but survival rates compared to radical hysterectomy (RH) have been scarcely reported. The aim of this study was to analyse the oncological outcomes of FSS compared to a balanced group of standard RH. Methods: A retrospective multicentre study of ECC patients who underwent FSS or RH was carried out in 12 tertiary hospitals in Spain between January 2005 and January 2019. The experimental group included patients who underwent a simple and radical trachelectomy, and the control group included patients who underwent RH. Optimal 1:1 propensity score (PS) matching analysis was performed to balance the series. Results: The study included 222 patients with ECC; 111 (50%) were treated with FSS, and 111 (50%) were treated with RH. After PS matching, a total of 38 patients in the FSS group and 38 patients in the RH group were analysed. In both groups, the overall survival (HR 2.5; CI 0.89, 7.41) and recurrence rates (28.9% in the FSS group vs. 13.2% in RH group) were similar. The rate of disease-free survival at 5 years was 68.99% in the FSS group and 88.01% in the RH group (difference of −19.02 percentage points; 95% CI −32.08 to −5.96 for noninferiority). In the univariate analysis, only tumour size reached statistical significance. Conclusion: FSS offers excellent disease-free and overall survival in women with ECC with fertility desire and is not inferior compared to RH.

Differences in the Impact of Heart Rate Variability on the Surgical Approach in Patients With Early Cervical Cancer: Laparoscopic versus Open Surgery.

BackgroundEvidence suggests that the risk of recurrence and death in patients with early cervical cancer (ECC) undergoing minimally invasive surgery is significantly higher than that in patients undergoing open surgery. However, the mechanisms underlying such a difference remain unclear. Heart rate variability (HRV) represents autonomic nerve activity, which is related to tumorgenesis and can be used as a prognostic indicator for various cancers. The main purpose of this study was to explore the difference in the effects of laparoscopic and open surgery on HRV in ECC patients.MethodsA total of 68 ECC (FIGO IA1 with lymphovascular space invasion -IIA2) patients undergoing radical hysterectomy for the first time (84% open group vs. 16% laparoscopic group) were included. A single-lead micro-ECG recorder was used to collect 5 min electrocardiograms 1 day before the operation and 3 days after the operation, and then HRV time domain and frequency domain indices were analyzed, including mean heart rate (MeanHR), maximum heart rate (MaxHR), minimum heart rate (MinHR), the standard deviation of all normal-to-normal intervals (SDNN), the root mean square of successive interval differences (RMSSD), very low-frequency power (VLF), low-frequency power (LF), high-frequency power (HF), total power (TP), and the ratio of LF to HF (LF/HF).ResultsHeart rate (i.e., MeanHR, MaxHR, and MinHR) were significantly higher, and HRV (i.e., SDNN, RMSSD, LF, HF, and TP) were significantly lower after the operation than before the operation in both the laparoscopic and open groups (P < 0.05). The postoperative reduction in RMSSD and HF was significantly higher in the laparoscopic group than in the open group (P < 0.05).ConclusionsThese data suggest that radical hysterectomy can lead to increased heart rate and decreased HRV in patients with ECC, which can negatively affect cardiac autonomic regulation. Compared with open surgery, laparoscopic surgery has a greater negative impact on the HRV of ECC patients.

Survival Impacts of Perineural Invasion on Patients Under Different Radical Hysterectomies Due to Early Cervical Cancer.

ObjectiveCervical cancer is a common gynecological malignancy. In addition to the open radical hysterectomy (ORH) and laparoscopic radical hysterectomy (LRH), laparoscopic nerve-sparing radical hysterectomy (LNSRH) could be another treatment option since it could preserve urinary, colorectal, and sexual functions. However, LNSRH might result in early cancer metastasis and recurrence due to inadequate tumor resection. Additionally, whether LNSRH should be considered based on perineural invasion (PNI) status remains controversial. To assess different types of hysterectomy on the outcome of early cervical cancer with PIN.MethodsA retrospective study was performed in early cervical cancer patients who received ORH, LRH, or LNSRH between January 2012 and December 2019. Age, FIGO cancer stages, histopathological types, tumor size, histological grade, invasion depth, lymph node metastasis, lymphovascular space invasion, and PNI were documented. Disease-free survival (DFS) and overall survival (OS) were recorded.ResultsA total of 174 patients were included, with 33, 69, and 72 patients received LRH, ORH, and LNSRH, respectively. Twenty-one patients (12.1%) had PNI. DFS (P = 0.000) and OS (P = 0.022) periods were shortened in positive PNI patients than in negative PNI patients (P = 0.000 and 0.022, respectively). In patients with positive PNI, lymph node metastasis, but not the surgery type, was an independent risk factor for DFS and OS (P = 0.000).ConclusionEarly cervical cancer patients with PNI had shorter postoperative DFS and OS periods. In these patients, lymph node metastasis, but not the type of hysterectomy, was independently associated with DFS and OS.

Diagnosis of Early Cervical Cancer with a Multimodal Magnetic Resonance Image under the Artificial Intelligence Algorithm.

This research was conducted to explore the value of multimodal magnetic resonance imaging (MRI) based on the alternating direction algorithm in the diagnosis of early cervical cancer. 64 patients diagnosed with early cervical cancer clinicopathologically were included, and according to the examination methods, they were divided into A group with conventional multimodal MRI examination and B group with the multimodal MRI examination under the alternating direction algorithm. The diagnostic results of two types of multimodal MRI for early cervical cancer staging were compared with the results of clinicopathological examination to judge the application value in the early diagnosis of cervical cancer. The results showed that in the 6 randomly selected samples of early cervical cancer patients, the peak signal-to-noise ratio (PSNR) and structural similarity image measurement (SSIM) of multimodal MRI images under the alternating direction algorithm were significantly higher than those of conventional multimodal MRI images and the image reconstruction was clearer under this algorithm. By comparing MRI multimodal staging, statistical analysis showed that the staging accuracy of B group was 75%, while that of A group was only 59.38%. For the results of postoperative medical examinations, the examination consistency of B group was better than that of A group, with a statistically significant difference (P < 0.05). The area under the receiver operating characteristic (ROC) curve (AUC) of B group was larger than that of A group; thus, sensitivity was improved and misdiagnosis was reduced significantly. Multimodal MRI under the alternating direction algorithm was superior to conventional multimodal MRI examination in the diagnosis of early cervical cancer, as the lesions were displayed more clearly, which was conducive to the detection rate of small lesions and the staging accuracy. Therefore, it could be used as an ideal MRI method for the assistant diagnosis of cervical cancer staging.

Cervical conization before primary radical hysterectomy has a protective effect on disease recurrence in early cervical cancer: A two-center matched cohort study according to surgical approach

ObjectiveTo ascertain whether cervical conization before radical hysterectomy (RH) has a protective effect on survival outcomes in early cervical cancer, taking into account the surgical approach. MethodsFrom cervical cancer cohorts of two institutions, we identified node-negative, margin-negative, parametria-negative, 2009 FIGO stage IB1 cervical cancer patients who received primary Type C RH between July 2006 and June 2020. Patients were divided into conization group (n = 144) and control group (n = 434). We conducted three independent 1:1 propensity score matching processes for histology, lymphovascular space invasion, cervical tumor size, and surgical approach (all patients, those who underwent open surgery, and those who underwent minimally invasive surgery [MIS]). Survival outcomes were compared. ResultsOverall, the conization group had less cervical tumor size and received MIS more frequently (P = 0.010) and adjuvant treatment less often (P = 0.002) versus the controls. After matching, the conization group showed significantly better disease-free survival (DFS) versus control (3-year DFS rate, 94.2% vs. 86.3%; P = 0.012), but similar overall survival. Among the open RH matched patients (n = 96), no difference in DFS was observed between the conization and control groups (P = 0.984). In contrast, among the MIS RH matched patients (n = 192), the conization group showed significantly better DFS versus control (3-year DFS rate, 95.7% vs. 82.9%; P = 0.005). In multivariate analysis adjusting for cervical tumor size and adjuvant treatment, conization was identified as an independent favorable prognostic factor for DFS (adjusted HR, 0.318; 95% CI, 0.134–0.754; P = 0.009). ConclusionsPreoperative cervical conization might reduce the disease recurrence rate in early cervical cancer patients who undergo primary MIS RH.

Validation of Potential Protein Markers Predicting Chemoradioresistance in Early Cervical Cancer by Immunohistochemistry.

BackgroundIn a previous study, a proteomic panel consisting of BCL-2, HER2, CD133, CAIX, and ERCC1 significantly predicted survival in patients with locally advanced cervical cancer. However, the prognostic significance of these proteins has not been assessed in early cervical cancer. The present study investigated the clinical significance and chemoradioresistance prediction power of these proteins in patients with early-stage cervical cancer.Materials and MethodsBCL-2, HER2, CD133, CAIX, and ERCC1 expression was determined by the immunohistochemical staining of 336 cervical cancer tissue microarrays. The associations of these proteins with clinicopathologic characteristics and disease progression were assessed.ResultsThere was a trend of low CAIX expression (p=0.082) and high ERCC1 expression (p=0.059) in patients with a favorable response to adjuvant radiation. High HER2 expression was significantly associated with shorter disease-free survival (DFS) in the total group (5-year DFS of 80.1% vs. 92.2%, p=0.004). A prognostic significance remained in multivariate analysis (Hazard ratio, HR=2.10, p=0.029). In the adjuvant radiation group, low CAIX and high ERCC1 expression indicated significantly unfavorable DFS (75.0% vs. 89.0%, p=0.026 and 76.8% vs. 88.6%, p=0.022, respectively). Low CAIX expression remained an independent prognostic marker in multivariate analysis (HR=0.45, p=0.037). The combined molecular-clinical model using random survival forest method predicted DFS with improved power compared with that of the clinical variable model (C-index 0.77 vs. 0.71, p=0.006).ConclusionHER2, CAIX, and ERCC1 expression can be predictive protein markers for clinical outcomes in early cervical cancer patients treated primarily with radical surgery with or without adjuvant radiation.

Survival Outcomes in Patients With 2018 FIGO Stage IA2-IIA2 Cervical Cancer Treated With Laparoscopic Versus Open Radical Hysterectomy: A Propensity Score-Weighting Analysis.

ObjectiveTo compare the survival and recurrence outcomes between open and laparoscopic radically hysterectomy (RH) for stage IA2-IIA2 cervical cancer based on Federation International of Gynecology and Obstetrics (FIGO) 2018.MethodsData of 1,373 early cervical cancer patients undergoing open or laparoscopic radically hysterectomy at ShengJing Hospital of China Medical University between January 1, 2013, and December 31, 2016, were retrospectively reviewed. Propensity score-based inverse probability of treatment weighting (PS-IPTW) was used to balance the covariates between the two groups.ResultsA total of 705 cervical cancer patients of FIGO 2009 stage IA2-IIA2 were finally enrolled in this study. After IPTW adjustment, the OS (HR = 2.095, 95% CI: 1.233-3.562, P = 0.006) and PFS (HR = 1.950, 95%CI: 1.194-3.184, P = 0.008) rates were significantly higher in the open RH (ORH) group compared with the laparoscopic RH (LRH) group. Then after re-staging according to the FIGO 2018 staging system, 561 patients still belonged to stage IA2-IIA2, 144 patients were upgraded to stage IIIC1p-IIIC2p. The ORH group had a significantly superior OS (HR = 1.977, 95%CI: 1.077-3.626, P = 0.028) and PFS (HR = 1.811, 95%CI: 1.046-3.134, P = 0.034) compared with the LRH group after PS-IPTW analysis. Furthermore, in patients with no high and intermediate risks, difference of the OS (HR = 1.386, 95%CI: 0.287-6.69, P = 0.684) and PFS (HR = 1.524, 95%CI: 0.363-6.396, P = 0.565) rates between the two groups were with no statistical meaning.ConclusionsOutcomes of this retrospective cohort study were in compliance with indications for ORH recommended by the National Comprehensive Cancer Network guidelines Version 1, 2021. However, LRH showed non-inferiority for patients with no prognostic risk factors compared with ORH.

Prognostic significance of poorly differentiated histology and impact of adjuvant chemotherapy in early squamous cell carcinoma of cervix uteri.

ObjectiveThis study is to determine whether the addition of cisplatin‐based chemotherapy after radical hysterectomy will improve the survival of low‐risk squamous cervical carcinoma with poor differentiation.MethodsPatients with low‐risk squamous cervical cancer (FIGO IA2–IIA, absent high‐ and intermediate‐risk factors after pathological evaluation) were eligible for this study. As first, the prognostic relevance of G3 versus G1/G2 among patients with low‐risk squamous cervical cancer was analyzed, then, the oncological results of postoperative chemotherapy among low‐risk squamous cervical cancer with poor differentiation was explored.ResultsTotally, there were 367 low‐risk squamous cervical cancer patients, of whom 161 were poor‐differentiated (47 in the chemotherapy group and 114 in the nonchemotherapy group), with a median follow‐up time of 56 months. Patients with G3 displayed a significantly worse overall survival (p = 0.035), and a higher recurrence rate (p = 0.014) than patients with G1/G2. Compared with the nonchemotherapy group, the hazard ratios (95%CI) for recurrence‐free survival in the chemotherapy group was 0.24 (0.06–0.93), (p = 0.038). No difference in overall survival was observed between the chemotherapy group and the nonchemotherapy group.ConclusionsThe addition of cisplatin‐based chemotherapy following surgery significantly improved recurrence‐free survival for low‐risk, poor differentiation, and early stage squamous cervical cancer patients.
