    早期宫颈癌(CC)患者对保留生育力的手术(FSS)的需求正在增加。本研究旨在评估15-39岁的I期CC患者(通常称为青少年和年轻人(AYAs))的局部切除术替代子宫切除术的可行性,这些患者具有不同的临床病理特征。
    使用监视,流行病学,和最终结果(SEER)数据库,我们确定了在2000年至2020年之间诊断的患者。我们检查了不同年龄段的治疗干预措施,组织学类型的程度,肿瘤分化,和肿瘤分期。局部切除的效果与通过比较总生存率(OS)和疾病特异性生存率(DSS)评估子宫切除术.
    本研究共纳入了10,629名I期AYA宫颈癌患者。在这些患者中,24.5%接受了局部切除以保存生育能力,67.3%接受了根治性子宫切除术。对于宫颈鳞状细胞癌(SCC)患者,长期结果有利于局部切除而不是子宫切除术,在患有腺鳞状细胞癌(ASCC)的患者中观察到类似的趋势。然而,宫颈腺癌(AC)患者的预后相当.在高分化和中分化肿瘤的患者中,与子宫切除术相比,局部切除术显示出更好的OS。对于低分化和未分化肿瘤患者,两种手术干预措施的预后均无明显差异。在IA期患者中,局部切除术被认为是子宫切除术的可行替代方案.在IB1-IB2阶段,FSS产生的预后结果与子宫切除术相当。相反,IB3期患者局部切除术后的5年OS和DSS明显短于子宫切除术患者.
    在IA-IB2期(直径≤4cm)AYA患者中,局部切除可能是保留生育力的可行选择。SCC的组织学类型,AC,ASCC,随着差异化,在确定这些患者的生育力保留策略时,不应将其作为限制性因素。早期患者,良好或中等分化的SCC可能受益于局部切除手术,即使生育保护不是主要目标。
    UNASSIGNED: The demand for fertility-sparing surgery (FSS) is increasing among patients with early-stage cervical cancer (CC). This study aimed to evaluate the feasibility of local excision as an alternative to hysterectomy in stage I CC patients aged 15-39 years-commonly referred to as adolescents and young adults (AYAs)-with varying clinicopathological characteristics.
    UNASSIGNED: Using the Surveillance, Epidemiology, and End Results (SEER) database, we identified patients diagnosed between 2000 and 2020. We examined treatment interventions across different age groups, degrees of histological types, tumor differentiation, and tumor stages. The effect of local excision vs. hysterectomy was assessed by comparing overall survival (OS) and disease-specific survival (DSS) rates.
    UNASSIGNED: A total of 10,629 stage I AYA cervical cancer patients were included in this study. Among these patients, 24.5% underwent local excision for fertility preservation, while 67.3% underwent radical hysterectomy. For patients with cervical squamous cell carcinoma (SCC), long-term outcomes favored local excision over hysterectomy, and a similar trend was observed in those with adenosquamous cell carcinoma (ASCC). However, the prognosis was comparable among patients with cervical adenocarcinoma (AC). In patients with well- and moderate- differentiated tumors, local excision demonstrated superior OS compared to hysterectomy. No significant differences in prognosis were found between the two surgical interventions for patients with poorly differentiated and undifferentiated tumors. In stage IA patients, local excision was considered a viable alternative to hysterectomy. In stage IB1-IB2, FSS yielded prognostic outcomes comparable to those of hysterectomy. Conversely, patients with stage IB3 exhibited significantly shorter 5-year OS and DSS following local excision than those who underwent hysterectomy.
    UNASSIGNED: In stage IA-IB2 (diameter ≤4 cm) AYA patients, local excision may serve as a viable option for fertility preservation. The histological type of SCC, AC, and ASCC, along with differentiation, should not serve as restrictive factors in determining fertility preservation strategies for these patients. Patients with early-stage, well- or moderately-differentiated SCC may benefit from local excision surgery, even when fertility preservation is not the primary objective.

    目的探讨床旁助手的工作经验和学习曲线对机器人辅助腹腔镜早期宫颈癌根治术短期安全性和有效性的影响。
    我们的研究回顾性检索了在广西医科大学第一附属医院接受机器人辅助腹腔镜根治性子宫切除术的120例早期宫颈癌患者。根据两位床边助手(BA)的不同工作经验,患者被分为研究组(无经验BA1)和对照组(有经验BA2).此外,分别绘制这些BAs的学习曲线,并通过累积求和将其分为两个不同的阶段:第一学习阶段和第二主阶段。
    就工作经验而言,将BA1与更有经验的BA2进行比较,尽管平均手术时间延长了29分钟(P<0.001),它没有增加手术并发症的发生率[24.4%VS29.1%,P=0.583],切缘阳性[4.9%VS7.6%,P=0.714],术中器官损伤[0%VS2.5%,P=0.546],淋巴结数目差异无统计学意义[19VS15,P=0.103]。此外,比较同一个床边助手的两个不同阶段,手术并发症的发生率没有显著增加,切缘阳性,术中器官损伤,除学习期手术时间稍长约20min外,BA1和BA2均无淋巴结数(P>0.05).
    在机器人辅助腹腔镜下早期宫颈癌根治术中,工作经验不足和BA的学习阶段只会导致手术时间的轻微延长,不会导致更差的短期手术结果。
    UNASSIGNED: Aim to investigate the impact of bedside assistant\'s work experience and learning curve on the short-term safety and efficacy in robotic-assisted laparoscopic radical hysterectomy for early-stage cervical cancer.
    UNASSIGNED: Our research retrospectively retrieved 120 cases of early-stage cervical cancer patients who underwent robotic-assisted laparoscopic radical hysterectomy at the First Affiliated Hospital of Guangxi Medical University. According to the different work experiences of the two bedside assistants (BA), patients were divided into a research group (inexperienced BA 1) and a control group (experienced BA 2). Furthermore, the learning curves of these BAs were plotted separately and divided into two distinct phases by cumulative summation: the first learning phase and the second master phase.
    UNASSIGNED: In terms of work experience, comparing BA 1 with BA 2 who was more experienced, although the average operative time was prolonged by 29 min (P<0.001), it did not increase the incidence of operative complication [24.4 % VS 29.1 %, P = 0.583], positive resection margin [4.9 % VS 7.6 %, P = 0.714], intraoperative organ damage [0 % VS 2.5 %, P = 0.546] and there was no significant difference in the number of lymph nodes [19 VS 15, P = 0.103]. Additionally, comparing two distinct phases of the same bedside assistant, there was no significant increasing rate in terms of operative complication, positive resection margin, intraoperative organ damage, and the number of lymph nodes (P>0.05) neither BA 1 nor BA 2, except for a slight extension of operative time about 20 min in learning phase (P<0.05).
    UNASSIGNED: In robotic-assisted laparoscopic radical hysterectomy for early-stage cervical cancer, work inexperience and the learning phase of BA only result in a slight extension of operative time, without causing worse short-term surgical outcomes.

    Adjuvant treatments are valuable to decrease the recurrence rate and improve survival for early-stage cervical cancer patients (ESCC), Therefore, recurrence risk evaluation is critical for the choice of postoperative treatment. A magnetic resonance imaging (MRI) based radiomics nomogram integrating postoperative adjuvant treatments was constructed and validated externally to improve the recurrence risk prediction for ESCC.
    212 ESCC patients underwent surgery and adjuvant treatments from three centers were enrolled and divided into the training, internal validation, and external validation cohorts. Their clinical data, pretreatment T2-weighted images (T2WI) were retrieved and analyzed. Radiomics models were constructed using machine learning methods with features extracted and screen from sagittal and axial T2WI. A nomogram for recurrence prediction was build and evaluated using multivariable logistic regression analysis integrating radiomic signature and adjuvant treatments.
    A total of 8 radiomic features were screened out of 1020 extracted features. The extreme gradient boosting (XGboost) model based on MRI radiomic features performed best in recurrence prediction with an area under curve (AUC) of 0.833, 0.822 in the internal and external validation cohorts, respectively. The nomogram integrating radiomic signature and clinical factors achieved an AUC of 0.806, 0.718 in the internal and external validation cohorts, respectively, for recurrence risk prediction for ESCC.
    In this study, the nomogram integrating T2WI radiomic signature and clinical factors is valuable to predict the recurrence risk, thereby allowing timely planning for effective treatments for ESCC with high risk of recurrence.

    目的:保留生育力的手术(FSS)的目的是在保持生育力和优化生殖结果的同时,达到不劣于根治性治疗的肿瘤结局。这项研究评估了FSS后早期宫颈癌幸存者的体外受精(IVF)结局。比较激进和非激进的方法。
    方法:这项回顾性分析使用了匈牙利国家健康保险基金(2004-2022)的数据,该数据涉及在10个匈牙利生育诊所的FSS治疗早期宫颈癌后接受IVF治疗的患者。患者分为根治性和非根治性手术组,在非根治性手术中保留子宫动脉。使用RStudio(R软件版本:4.2.2)进行统计学分析。学生t检验用于比较组均值,Fisher的精确检验用于评估分类变量之间的独立性和分布,估计赔率。
    结果:该研究分析了来自122个IVF治疗周期的数据,涉及36例患者。非激进组的活产率明显较高(83%,5/6与激进组(17%,5/30)。此外,非根治性组的着床率和每次取卵累积活产率显著较高(37%,7/19和55%,分别为6/11)与激进组(8%,12/148和6%,分别为5/80)。
    结论:这是评估年轻宫颈癌幸存者接受FSS的IVF结局的最大研究。研究结果表明,不太激进的手术与更好的IVF结局相关。这些结果强调了在为早期宫颈癌患者选择FSS时同时考虑肿瘤安全性和生殖结果的重要性。它还强调了进行较不彻底的手术的生殖益处。
    Fertility-sparing surgery (FSS) aims to achieve oncological outcomes that are non-inferior to radical treatment while preserving fertility and optimizing reproductive results. This study assesses in vitro fertilization (IVF) outcomes in early-stage cervical cancer survivors following FSS, comparing radical and non-radical approaches.
    This retrospective analysis used data from Hungary\'s National Health Insurance Fund (2004-2022) on patients who underwent IVF treatment following FSS for early-stage cervical cancer at ten Hungarian fertility clinics. Patients were classified into radical and non-radical surgical groups, with the uterine arteries being spared in the non-radical procedures. RStudio (R software version: 4.2.2) was used for statistical analysis. Student\'s t-test was used to compare group means, and Fisher\'s exact test was applied to assess independence and distributions between categorical variables, and to estimate odds.
    The study analyzed data from 122 IVF treatment cycles involving 36 patients. The non-radical group had a significantly higher live birth rate (83%, 5/6 compared to the radical group (17%, 5/30). Additionally, the non-radical group had a significantly higher implantation rate and cumulative live birth rate per oocyte retrieval (37%, 7/19 and 55%, 6/11 respectively) compared to the radical group (8%, 12/148 and 6%, 5/80 respectively).
    This is the largest study to evaluate IVF outcomes in young cervical cancer survivors who have undergone FSS. The findings suggest that less radical procedures are associated with significantly better IVF outcomes. These results emphasize the importance of considering oncological safety and reproductive outcomes together when choosing FSS for early-stage cervical cancer patients. It also highlights the reproductive benefits of performing less radical surgery.

    背景:本系统评价(SR)和荟萃分析旨在比较早期宫颈癌患者SH和RH之间的手术相关结果和肿瘤学结果。
    方法:我们系统地搜索了数据库,包括PubMed,Embase和Cochrane收集比较SH和RH组在IA2和IB1期宫颈癌患者中肿瘤和手术相关结果的研究。随机效应模型通过ReviewManagerV.5.4计算每个主要结果的加权平均差。
    结果:我们的研究纳入了7项研究,包括6977名患者。对于肿瘤学结果,我们发现复发率[OR=0.88;95%CI(0.50,1.57);P=0.68]和总生存期(OS)[OR=1.23;95%CI(0.69,2.19)没有统计学差异,P=0.48]。两组间LVSI阳性发生率和淋巴结转移无差异。关于手术相关的结果,综合效应显示膀胱损伤[OR=0.28;95%CI(0.08,0.94),P=0.04]和膀胱功能障碍[OR=0.10;95%CI(0.02,0.53),RH组P=0.007]高于SH组。
    结论:这项荟萃分析表明,在接受SH或RH治疗的IA2-IB1期宫颈癌患者中,复发率和总生存率没有显着差异。而SH组有更好的手术相关结局。这些数据证实了缩小早期宫颈癌RH适应症的必要性。
    BACKGROUND: This systematic review (SR) and meta-analysis aims to compare the surgery-related results and oncological outcomes between SH and RH in patients with early-stage cervical cancer.
    METHODS: We systematically searched databases including PubMed, Embase and Cochrane to collect studies that compared oncological and surgery-related outcomes between SH and RH groups in patients with stage IA2 and IB1 cervical cancer. A random-effect model calculated the weighted average difference of each primary outcome via Review Manager V.5.4.
    RESULTS: Seven studies comprising 6977 patients were included into our study. For oncological outcomes, we found no statistical difference in recurrence rate [OR = 0.88; 95% CI (0.50, 1.57); P = 0.68] and Overall Survival (OS) [OR = 1.23; 95% CI (0.69, 2.19), P = 0.48]. No difference was detected in the prevalence of positive LVSI and lymph nodes metastasis between the two groups. Concerning surgery-related outcomes, the comprehensive effects revealed that the bladder injury [OR = 0.28; 95% CI (0.08, 0.94), P = 0.04] and bladder disfunction [OR = 0.10; 95% CI (0.02, 0.53), P = 0.007] of the RH group were higher compared to the SH group.
    CONCLUSIONS: This meta-analysis suggested there are no significant differences in terms of both recurrence rate and overall survival among patients with stage IA2-IB1 cervical cancer undergoing SH or RH, while the SH group has better surgery-related outcomes. These data confirm the need to narrow the indication for RH in early-stage cervical cancer.

    微创手术治疗早期宫颈癌尚有争议。传统的结肠切除术方法被认为是造成低等肿瘤学结果的原因。关于保护性结肠切除术是否可以优化微创技术并改善早期宫颈癌女性预后的证据仍然有限。根据现有文献,我们进行了系统评价和荟萃分析,以比较接受微创根治性子宫切除术和保护性子宫切除术治疗的患者与接受开放手术治疗的患者的肿瘤学结果。我们探索了PubMed,Embase,Cochrane图书馆,和ClinicalTrials.gov从成立到2022年12月。纳入标准为:(1)以英文发表的随机对照试验或观察性研究,(2)比较微创根治性子宫切除术与保护性子宫切除术与早期宫颈癌开腹根治性子宫切除术的研究,和(3)比较生存结果的研究。两名审稿人进行了筛选,数据提取,独立进行质量评估。该研究共纳入了8项2020名女性的回顾性队列研究,其中821人属于微创手术组,其中1199人属于开放手术组。微创手术组的无复发生存率和总生存率均与开放手术组相似(合并风险比,分别为0.88和0.78;95%置信区间,分别为0.56-1.38和0.42-1.44)。与腹部根治性子宫切除术相比,微创根治性子宫切除术与保护性子宫切除术治疗早期宫颈癌的无复发生存率和总生存率相似。保护性结肠切除术可能是改良微创技术的保证方法。
    Minimally invasive surgery on treatment of early-stage cervical cancer is debatable. Traditional approaches of colpotomy are considered responsible for an inferior oncological outcome. Evidence on whether protective colpotomy could optimize minimally invasive technique and improve prognoses of women with early-stage cervical cancer remains limited. We produced a systematic review and meta-analysis to compare oncological outcomes of the patients treated by minimally invasive radical hysterectomy with protective colpotomy to those treated by open surgery according to existing literature. We explored PubMed, Embase, the Cochrane Library, and ClinicalTrials.gov from inception to December 2022. Inclusion criteria were: (1) randomized controlled trials or observational studies published in English, (2) studies comparing minimally invasive radical hysterectomy with protective colpotomy to abdominal radical hysterectomy in early-stage cervical cancer, and (3) studies comparing survival outcomes. Two reviewers performed the screening, data extraction, and quality assessment independently. A total of 8 retrospective cohort studies with 2020 women were included in the study, 821 of whom were in the minimally invasive surgery group, and 1199 of whom were in the open surgery group. The recurrence-free survival and overall survival in the minimally invasive surgery group were both similar to that in the open surgery group (pooled hazard ratio, 0.88 and 0.78, respectively; 95% confidence interval, 0.56-1.38 and 0.42-1.44, respectively). Minimally invasive radical hysterectomy with protective colpotomy on treatment of early-stage cervical cancer had similar recurrence-free survival and overall survival compared to abdominal radical hysterectomy. Protective colpotomy could be a guaranteed approach to modifying minimally invasive technique.

    背景:绝经前妇女的宫颈癌发病率正在上升,和保留生育力的手术在这个年轻人群中提供了一个重要的选择。缺乏证据表明应使用何种肿瘤大小截止值来定义保留生育力的手术的候选资格。
    目的:我们试图描述在最大直径≤4cm的宫颈癌患者中,保留生育力的手术(与标准手术相比)与预期寿命之间的关系如何因肿瘤大小而异。我们的次要目标是根据肿瘤大小量化接受保留生育力手术的患者接受辅助放疗的可能性。
    方法:我们在国家癌症数据库中确定了年龄≤45岁的患者,在2006年至2018年之间诊断为I期宫颈癌,肿瘤≤4cm,未接受术前放疗或化疗,并接受了保留生育能力的手术(锥形或膀胱切除术,简单或根治性)或标准手术(简单或根治性子宫切除术)作为主要治疗方法。进行倾向评分匹配,以比较接受保留生育力手术的患者和接受标准手术的患者。采用灵活的参数模型,根据保留生育力与标准手术的患者的肿瘤大小,量化诊断后5年内预期寿命的差异(受限平均生存时间;RMST)。此外,在那些接受了节育手术的人中,采用logistic回归模型探讨肿瘤大小与接受辅助放疗概率之间的关系.
    结果:共有11,946名患者符合纳入标准,其中904人(7.6%)接受了保留生育力的手术。在倾向得分匹配后,897例接受保留生育力手术的患者与接受标准手术的患者1:1匹配。尽管保留生育能力或进行标准手术的患者的5年预期寿命相似,但无论肿瘤大小如何,在肿瘤较小的患者中,与保留生育力手术相关的预期寿命差异的估计更为精确(1-cm肿瘤:RMST差异,-0.10个月;95%CI,-0.67至0.47)与较大肿瘤的患者(4-cm肿瘤:RMST差异,-0.11个月;95%CI,-3.79至3.57)。接受辅助放射的概率随肿瘤大小而增加,从1厘米肿瘤的5.6%(95%CI,3.9-7.9%)到4厘米肿瘤的37%(95%CI,24.3-51.8%)不等。
    结论:在诊断后的5年内,年龄≤4cm的I期癌症年轻患者在保留生育功能或标准手术后的生存结局相似.然而,因为很少有肿瘤>2厘米的患者接受了保留生育的手术,在这一人群中,不能排除临床上重要的生存差异.
    Cervical cancer incidence among premenopausal women is rising, and fertility-sparing surgery serves as an important option for this young population. There is a lack of evidence on what tumor size cutoff should be used to define candidacy for fertility-sparing surgery.
    We sought to describe how the association between fertility-sparing surgery (compared with standard surgery) and life expectancy varies by tumor size among patients with cervical cancers measuring ≤4 cm in largest diameter. Our secondary objective was to quantify the probability of undergoing adjuvant radiotherapy among patients who underwent fertility-sparing surgery as a function of tumor size.
    We identified patients in the National Cancer Database aged ≤45 years, diagnosed with stage I cervical cancer with tumors ≤4 cm between 2006 and 2018, who received no preoperative radiation or chemotherapy, and who underwent either fertility-sparing surgery (cone or trachelectomy, either simple or radical) or standard surgery (simple or radical hysterectomy) as their primary treatment. Propensity-score matching was performed to compare patients who underwent fertility-sparing surgery with those who underwent standard surgery. A flexible parametric model was employed to quantify the difference in life expectancy within 5 years of diagnosis (restricted mean survival time) based on tumor size among patients who underwent fertility-sparing and those who underwent standard surgery. In addition, among those who underwent fertility-sparing surgery, a logistic regression model was used to explore the relationship between tumor size and the probability of receiving adjuvant radiation.
    A total of 11,946 patients met the inclusion criteria of whom 904 (7.6%) underwent fertility-sparing surgery. After propensity-score matching, 897 patients who underwent fertility-sparing surgery were matched 1:1 with those who underwent standard surgery. Although the 5-year life expectancy was similar among patients who had fertility sparing surgery and those who had standard surgery regardless of tumor sizes, the estimates of life-expectancy differences associated with fertility-sparing surgery were more precise among patients with smaller tumors (1-cm tumor: restricted mean survival time difference, -0.10 months; 95% confidence interval, -0.67 to 0.47) than among those with larger tumors (4-cm tumor: restricted mean survival time difference, -0.11 months; 95% confidence interval, -3.79 to 3.57). The probability of receiving adjuvant radiation increased with tumor size, ranging from 5.6% (95% confidence interval, 3.9-7.9) for a 1-cm tumor to 37% (95% confidence interval, 24.3-51.8) for a 4-cm tumor.
    Within 5 years of diagnosis, young patients with stage I cancers measuring ≤4 cm had similar survival outcomes after either fertility-sparing surgery or standard surgery. However, because few patients with tumors >2 cm underwent fertility-sparing surgery, a clinically important survival difference could not be excluded in this population.

    目的:分析临床早期宫颈癌(ESCC)患者行子宫切除及放疗后复发的影响因素。
    方法:我们收集了ESCC患者的数据,根据2009年国际妇产科联合会(FIGO)分期标准分期,在2012年至2019年期间接受了子宫切除术后的辅助放疗。这些患者随后使用2018年FIGO标准进行了重新治疗。单变量和多变量分析,连同列线图分析,进行了探讨与无复发生存(RFS)相关的因素。
    结果:共有310例患者符合纳入标准,中位随访时间为46个月。其中,根据2018年FIGO分期标准,126例ESCC患者因淋巴结转移(LNM)在手术后恢复至III期C1或III期C2。其中,60例(19.3%)复发。1-,3-,5年RFS率为93.9%,82.7%,和79.3%,分别。多因素分析显示,阳性淋巴结(LNs)的数量,肿瘤直径(TD)>4厘米,和宫旁浸润(PI)与复发有关。列线图显示了它们对3年和5年RFS的预测价值。值得注意的是,LNM患者的5年复发率(RR)增加了30.2%,特别是LN≥3(45.5%)。III期C2患者的RR明显高于IIIC1患者(56.5%vs.24.3%,p<0.001)。TD>4cm患者的5年RFS占65.8%,显著低于TD≤4cm的(88.2%)。亚组分析显示,III期C2患者的5年RR高于III-C1患者(56.5%vs.24.3%,p<0.001),证明RFS存活曲线有显著差异。
    结论:临床上ESCC患者行子宫切除术后辅助放疗的RR与阳性LN的数量相关,TD>4cm,和PI。应重视ESCC中LNM与根治性子宫切除术后复发的共同高危因素。
    To analyze recurrent factors in patients with clinical early-stage cervical cancer (ESCC) following hysterectomy and adjuvant radiotherapy.
    We collected data from patients with ESCC, staged according to the 2009 Federation International of Gynecology and Obstetrics (FIGO) staging criteria, who underwent hysterectomy followed by adjuvant radiotherapy between 2012 and 2019. These patients were subsequently restaged using the 2018 FIGO criteria. Univariable and multivariable analyses, along with nomogram analyses, were conducted to explore factors associated with recurrence-free survival (RFS).
    A total of 310 patients met the inclusion criteria, with a median follow-up time of 46 months. Among them, 126 patients with ESCC were restaged to stage III C1 or III C2 after surgery due to lymph node metastasis (LNM) based on the 2018 FIGO staging criteria. Of these, 60 (19.3%) experienced relapse. The 1-, 3-, and 5-year RFS rates were 93.9%, 82.7%, and 79.3%, respectively. Multivariate analysis revealed that the number of positive lymph nodes (LNs), tumor diameter (TD) > 4 cm, and parametrial invasion (PI) were associated with recurrence. The nomogram indicated their predictive value for 3-year and 5-year RFS. Notably, the 5-year recurrence rate (RR) increased by 30.2% in patients with LNM, particularly those with ≥ 3 positive LNs (45.5%). Patients with stage III C2 exhibited a significantly higher RR than those with IIIC1 (56.5% vs. 24.3%, p < 0.001). The 5-year RFS for patients with TD > 4 cm was 65.8%, significantly lower than for those with TD ≤ 4 cm (88.2%). Subgroup analysis revealed higher 5-year RRs in patients with stage III C2 than that in patients with III-C1 (56.5% vs. 24.3%, p < 0.001), demonstrating a significant difference in the RFS survival curve.
    RR in patients with clinical ESCC after hysterectomy followed by adjuvant radiotherapy is correlated with the number of positive LNs, TD > 4 cm, and PI. Emphasis should be placed on the common high-risk factor of LNM association with recurrence after radical hysterectomy in ESCC.

    背景:本研究的目的是研究在接受根治性子宫切除术治疗的国际妇产科联合会(FIGO2009)I-IIA期宫颈癌患者术前18F-氟-2-脱氧-D-葡萄糖正电子发射断层扫描/计算机断层扫描(18F-FDGPET/CT)测量的最大标准化摄取值(SUVmax)的预测价值。
    方法:共纳入47例FIGOI-IIA期宫颈癌患者,这些患者术前进行活检和18F-FDGPET/CT,然后进行根治性子宫切除术。研究了SUVmax与病理危险因素或生存之间的相关性。
    结果:大肿瘤(≥4厘米)患者的平均SUVmax明显更高,晚期(IIA>IB>IA)和侵入深度>50%。有无盆腔淋巴结受累的患者之间的SUVmax没有显着差异(P=0.639)。有和无淋巴管浸润的原发肿瘤的SUVmax分别为12.95和10.35(P=0.5)。在总生存期(OS)和无病生存期(DFS)方面,高SUVmax和低SUVmax患者之间没有显着差异。使用从接收器工作特性(ROC)曲线分析获得的OS和DFS的最佳截止值7.65。与肿瘤大小<4cm相比,肿瘤大小>4cm的患者死亡率高5.9倍(P=0.09)。
    结论:本研究观察显示,尽管SUVmax与病理变量相关,它不能独立预测接受根治性子宫切除术治疗的FIGO期IA-IIA宫颈癌患者的肿瘤结局.这些结果表明,原发性肿瘤的SUVmax可用于风险分层,但不适用于手术治疗的早期宫颈癌患者的预后。未使用18F-FDGPET/CT的其他参数如代谢性肿瘤体积(MTV),肿瘤溶解糖酵解(TLG),小样本量,SUVmax计算中的变化,组织病理学异质性,将IA期患者纳入研究是本研究的限制因素.使用18F-FDGPET/CT的多代谢参数进一步研究大样本量,包括SUVmax,Suvmean,SUVpeak,需要MTV和TLG。
    BACKGROUND: The aim of the present study was to investigate the predictive value of maximum standardized uptake value (SUVmax) measured on preoperative 18F-fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography (18F-FDG PET/CT) in International Federation of Gynecology and Obstetrics (FIGO 2009) stage I-IIA cervical cancer patients who were treated with radical hysterectomy.
    METHODS: A total of 47 patients with FIGO stage I-IIA cervical cancer who were evaluated preoperatively with biopsy and 18F-FDG PET/CT followed by radical hysterectomy were included in the study. Correlation between SUVmax and pathological risk factors or survival was studied.
    RESULTS: The mean SUVmax was significantly higher in patients with large tumor size (≥4 cm), advanced stage (IIA>IB>IA) and depth of invasion >50%. No significant difference was noted in SUVmax between patients with and without pelvic lymph node involvement (P=0.639). SUVmax of the primary tumor with and without lymph-vascular invasion were 12.95 and 10.35, respectively (P=0.5). No significant difference was noted between patients with high SUVmax and low SUVmax with regards to overall survival (OS) and disease-free survival (DFS), using an optimal cut-off value of 7.65 for OS and DFS obtained from receiver operating characteristic (ROC) curve analysis. Patient with tumor size >4cm had 5.9 times more probability of mortality compared to tumor size <4cm (P=0.09).
    CONCLUSIONS: The present study observations showed that although SUVmax is associated with pathological variables, it does not independently predict oncological outcomes in FIGO stage IA-IIA cervical cancer patients who were treated with radical hysterectomy. These findings suggest that SUVmax of primary tumor may be used for risk stratification, but not for prognostication in surgically treated early-stage cervical cancer patients. Not using other parameters of 18F-FDG PET/CT like metabolic tumor volume (MTV), tumor lysis glycolysis (TLG), small sample size, variation in calculation of SUVmax, histopathologic heterogeneity, inclusion of stage IA patients in the study were constraints of present study. Further studies with large sample size using multi metabolic parameters of 18F-FDG PET/CT, including the SUVmax,SUVmean,SUVpeak, MTV and TLG are needed.
