Background More evidence has shown FDG PET/CT parameters might be associated with survival of patients with locally advanced cervical cancer (LACC) treated with concurrent chemo-radiotherapy (CCRT). Objectives To perform this meta-analysis to investigate the prognostic value of pretreatment FDG PET/CT parameters. Search strategy PubMed and Embase. Selection criteria Studies that met the following criteria were enrolled: patients treated with CCRT for LACC; FDG PET/CT scans performed before or during treatment; and relationship between the parameters of FDG PET/CT and the prognosis of patients were investigated. Data collection and analysis Pooled hazard ratios (HRs) with 95% confidence intervals (CIs) were used to estimate overall survival (OS) or event-free survival (EFS). Main results Higher primary tumor TLG (HR = 1.843, 95% CI = 1.100–3.086, P = 0.02) and MTV (HR = 2.06, 95% CI, 1.21–3.51, P = 0.007) were significantly associated with shorter EFS. Patients with high SUVmax have a shouter OS than those with low SUVmax (HR = 2.582, 95% CI 1.936–3.443, P <0.001). Primary tumor SUVmax (HR = 1.938, 95% CI, 1.203–3.054, P = 0.004) and nodal SUVmax (HR = 3.478, 95% CI = 2.006-6.029, P <0.001) were significantly correlated with EFS with relatively high heterogeneity (I2 = 84%, I2 = 69.4%, respectively). Nodal SUVmax (HR = 2.095, 95% CI = 2.027–2.166, P <0.001) were significantly correlated with OS with relatively high heterogeneity (I2 = 54.1%, P = 0.140). Other parameters had no detected association with survival. Conclusions Pretreatment FDG PET/CT parameters serve as a prognostic predictor.
Objective: To investigate the feasibility and diagnostic accuracy of endometrial biopsy using Li Brush sampler in IUD users. Design: Clinical research Setting: A public teaching hospital in China. Population: IUD users with irregular uterine bleeding and IUD non-users who arranged for dilatation and curettage at the First Affiliated Hospital of Xi’an Jiaotong University, China from January 2018 to January 2020. Methods: This study was conducted in two parts. Part Ⅰ was to assess the impact of Li Brush on the position of IUDs. Transvaginal ultrasound was used to locate IUDs before and after sampling. Part Ⅱ was to explore the diagnostic accuracy of Li Brush in detecting endometrial lesions. Both IUD users and non-users were recruited, and the sampling satisfaction and accuracy of Li Brush were evaluated. Main outcome Measures: The positions of IUDs before and after sampling, cytopathological and histopathological diagnosis, sampling satisfaction rate. Results: Seventeen cases in part Ⅰ confirmed no significant difference in the position of IUDs before and after sampling (p=0.20). 112 IUD users and 139 IUD non-users were recruited in part Ⅱ. The Li Brush achieved 94.64% and 92.09% sampling satisfaction in the IUD group and control group, respectively, and the overall diagnostic accuracy was 88.04% and 93.33% in the two groups. Conclusions: Li Brush used for endometrial biopsy did not affect the position of IUDs and had high sampling satisfaction and accuracy for endometrial diagnoses.
