Impact of the COVID-19 pandemic on the hospital attendance of patients with primary cervical cancer in Heilongjiang,China

Information regarding the impact of the coronavirus disease 2019 (COVID-19) pandemic on cervical cancer in mainland China is lacking. We explored its impact on the hospital attendance of patients with primary cervical cancer. We included 1918 patients with primary cervical cancer who initially attended Harbin Medical University Cancer Hospital between January 23, 2019, and January 23, 2021. Attendance decreased by 31%, from 1135 in 2019 to 783 in 2020, mainly from January to June (𝜒² = 73.362, P < .001). The percentage of patients detected by screening decreased from 12.1% in January-June 2019 to 5.8% in January-June 2020 (𝜒² = 7.187, P = .007). Patients with stage I accounted for 28.4% in 2020 significantly lower than 36.6% in 2019 (𝜒² = 14.085, P < .001), and patients with stage III accounted for 27.1% in 2020 significantly higher than 20.5% in 2019 (𝜒² = 11.145, P < .001). Waiting time for treatment was extended from 8 days (median) in January-June and July-December 2019 to 16 days in January-June (𝜒² = 74.674, P < .001) and 12 days in July-December 2020 (𝜒² = 37.916, P < .001). Of the 179 patients who delayed treatment, 164 (91.6%) were for the reasons of the healthcare providers. Compared to 2019, the number of patients in Harbin or non-Harbin in Heilongjiang Province and outside the province decreased, and cross-regional medical treatment has been hindered. The COVID-19 pandemic has negatively impacted cervical cancer patient attendance at the initial phase. These results are solid evidence that a strategy and mechanism for the effective attendance of cervical cancer patients in response to public health emergencies is urgently needed.

Can we increase the cervical cancer screening interval with an HPV test for women living with HIV? Results of a cohort study from Maharashtra,India

We are reporting (a) updated incidence of cervical intraepithelial neoplasia (CIN) among women who did not have colposcopic or histopathological disease at baseline and (b) disease outcomes among women treated for CIN and their follow-up HPV status; in a cohort of women living with HIV (WHIV). The median overall follow-up was 3.5 years (IQR 2.8-4.3). The incidence of any CIN and that of CIN 2 or worse disease was 16.7 and 7.0 per 1000 person-years of observation (PYO), respectively. Compared with women who were HPV negative at baseline, women who cleared HPV infection had 23.95 times increased risk of incident CIN 2 or worse lesions (95% CI 2.40-661.07). Women with persistent HPV infection had 138.18 times increased risk of CIN 2 or worse lesions (95% CI 20.30-3300.22). Complete disease regression was observed in 65.6% of the HPV positive women with high-grade CIN and were treated with thermal ablation but HPV persistence was seen in 44.8% of those with high-grade disease. Among those who did not have any disease at baseline and were also HPV negative, about 87% (95% CI 83.79-89.48) women remained HPV negative during consecutive HPV test/s with the median interval of 3.5 years. Long-term surveillance of WHIV treated for any CIN is necessary for the prevention of cervical cancer among them. Our study provides an early indication that the currently recommended screening interval of 3 to 5 years among WHIV may be extended to at least 5 years among HPV negative women. Increasing the screening interval can be cost saving and improve scalability among WHIV to support WHO's cervical cancer elimination initiative.     

宫颈癌幸存者社会疏离感现状及影响因素研究

目的 探讨宫颈癌幸存者社会疏离现状及其影响因素，为实施针对性干预提供参考。方法选取395例宫颈癌幸存者作为研究对象，采用一般情况调查表、一般疏离感量表、社会影响量表、社会支持评定量表进行调查。结果宫颈癌幸存者一般疏离感量表得分（41.98±6.81）分；家庭人均月收入、治疗后时间、病耻感总分、社会支持总分是社会疏离的主要影响因素(均P＜0.05），可以解释46.1%的变异量。结论宫颈癌幸存者社会疏离总体水平呈中等偏高。医护人员应关注宫颈癌幸存者的社会疏离水平，尤其是低收入、治疗后时间短的患者，可通过降低患者病耻感和提高患者社会支持水平，降低其社会疏离水平。     

短期非融合固定治疗枢椎齿状突Ⅱ型骨折后的颈椎活动度

[目的]探讨短期寰枢椎椎弓根螺钉非融合固定治疗枢椎齿状突Ⅱ型骨折后颈椎活动功能。[方法]2012年2月~2017年12月,选取枢椎齿状突II型骨折后接受后路寰枢椎椎弓根螺钉非融合内固定术,并二次手术取出内固定物的患者32例。对比患者自身前后两次手术后颈椎过伸过屈、左右旋转角度,同时参考正常人群颈椎活动度进行比较。[结果]32例患者均顺利完成C1/2椎弓根螺钉非融合内固定术,经影像学确认内固定位置良好,无血管、神经损伤等并发症的发生。于初次内固定术后4~15个月,平均(9.55±2.72)个月,32例患者再次入院行内固定取出术。取内固定术后平均随访(16.41±4.25)个月。末次随访时32例患者前屈、后伸、左旋转和右旋转ROM均显著大于取内固定之前角度(P<0.05),但仍显著不及正常人。[结论]短期寰枢椎椎弓根螺钉非融合内固定治疗枢椎齿状突骨折,可有效保留颈椎活动功能,值得临床推广应用。     

B7-H4及Fas、FasL与宫颈癌免疫逃逸机制的关系

目的:检测免疫共刺激分子B7-H4及Fas、FasL在不同宫颈组织中的表达，研究三者的异常表达与宫颈癌免疫逃逸机制的关系。方法:选择陕西省肿瘤医院病理科2014-2018年的石蜡包埋标本162例，采用免疫组织化学方法检测20例正常宫颈、30例宫颈上皮内瘤变(CIN)和112例I期-IV期宫颈癌组织中B7-H4及Fas、FasL的表达水平。结果:B7-H4在正常宫颈组、CIN组、宫颈癌组的阳性表达率分别为0、20.0%、47.32%，两两相比，具有显著性差异（P<0.05）。在112例宫颈癌病例中FIGO临床分期I期至IV期各期别宫颈癌组织B7-H4的阳表达率分别为16.67%、43.18%、70.83%、85.71%，各组间相比差异具有统计学意义。正常对照组Fas的阳性表达率是85.00％，CIN组43.33％，宫颈癌组41.96％，正常组与CIN、正常组与宫颈癌组相比差异均具有统计学意义（P<0.05），CIN组与宫颈癌组相比，无明显差异（P>0.05）。FasL的阳性表达率在正常组为20.00%，CIN组为50.00%，宫颈癌组为56.25%，正常组与CIN、宫颈癌组比较，差异具有统计学意义(P<0.05)，CIN组与宫颈癌组比较无显著差异;B7-H4阳性宫颈癌组Fas阳性表达率28.30%明显较B7-H4阴性宫颈癌组Fas阳性表达率54.24%低，差异具有统计学意义（P<0.05）；而B7-H4阳性宫颈癌组FasL阳性表达率79.25%明显高于B7-H4阴性宫颈癌组FasL阳性表达率35.59%，差异具有统计学意义（P<0.05）。结论:负性免疫共刺激分子B7-H4和Fas、FasL凋亡蛋白在宫颈癌的发生、进展中起到了重要作用，其协同作用可能为宫颈癌细胞逃逸机体免疫的机制之一。

子宫内膜癌三维超声血管血流参数与病理学预后指标的相关性

目的探讨子宫内膜癌三维超声血管血流参数与病理学预后指标的相关性。方法选择子宫内膜良性病变患者120例(良性组)与子宫内膜癌患者120例(癌变组),所有患者给予三维超声,记录血管血流参数;采用免疫组化法检测两组病灶病理学预后指标(IGF-1、IGF-2)表达情况并进行相关性分析。结果癌变组的超声病灶形态、内膜回声、增强强度、增强均度与良性组对比差异有统计学意义(P<0.05)。癌变组的IGF-1、IGF-2表达阳性率分别为90.8%、74.2%,显著高于良性组的28.3%、36.7%。癌变组中三维超声血流分级与良性组对比差异有统计学意义(P<0.05)。在癌变组中,直线相关分析显示三维超声血流分级与IGF-1、IGF-2表达阳性率呈显著正相关性(P<0.05)。结论子宫内膜癌患者多表现为IGF-1、IGF-2的高表达,三维超声血管血流分级程度比较高,两者存在相关性,可共同影响子宫内膜癌的发生。     

18F-FDG PET/CT代谢的可重复性研究进展

18F-脱氧葡萄糖(18F-FDG)PET／CT在恶性肿瘤的早期诊断、临床分期、疗效评价、监测复发及肿瘤放疗靶区定位中具有重要价值。为了使PET/CT能够更准确地进行恶性肿瘤的疗效评价，18F-FDG PET／CT代谢的可重复性研究显得尤为重要。本文就传统临床代谢参数值标准化摄取值（SUV）、代谢活性肿瘤体积（MATV）、总病灶糖酵解（TLG）、肿瘤与肝脏比率（TLR）、肿瘤与血液比率(SUR)及近年新兴的PET图像纹理分析等方面的可重复性研究进行概述。
