This study aims to compare the prostate cancer detection rate between magnetic resonance imaging (MRI)-transrectal ultrasound (TRUS) cognitive fusion targeted biopsy and systematic biopsy. A total of 614 patients who underwent transrectal prostate biopsy during 2016-2018 with multiparametric magnetic resonance imaging (mpMRI) were included. All patients with a PI-RADS V2 score ≥ 3 accepted both targeted biopsy and systematic biopsy, and those with a PI-RADS V2 score ≤ 2 only accepted systematic biopsy. Overall prostate cancer detection rate between the two biopsies was compared. MRI-TRUS cognitive fusion targeted biopsy identified 342 cases (75.7%) of prostate cancer while systematic biopsy identified 358 cases (79.2%). There was no significant difference in the detection rate between the two groups (χ2 = 1.621, P = 0.203). Targeted biopsy had significant fewer biopsy cores compared with systematic biopsy, reducing (9.3 ± 0.11) cores (P < 0.001) in average. Targeted biopsy had about 10.8% (P < 0.001) more tumor tissues in positive cores compared with systematic biopsy. The results show that both MRI-TRUS cognitive fusion targeted biopsy and systematic biopsy have good detection rate on prostate cancer. Cognitive targeted biopsy may reduce biopsy cores and provide more tumor tissues in positive cores.

ObjectiveTo explore the application and effect of clinical nursing pathway based on information-knowledge-attitude-practice (IKPA) theory in percutaneous renal needle biopsy.MethodsThis is a historical control study. A total of 460 patients who underwent percutaneous renal biopsy in West China Hospital of Sichuan University between April and December 2020 were prospectively recruited as the pathway group, and a clinical nursing pathway based on IKAP theory was implemented. By contrast, the data of 617 patients who underwent percutaneous renal biopsy and received routine care in the same hospital between April and December 2019 were retrospectively collected as the control group. The length of hospital stay, hospitalization expenses, the incidences of postoperative complications (macroscopic haematuria, perirenal hematoma, and acute urinary retention), the incidence of postoperative postural hypotension, and the management enrollment rate of chronic kidney disease patients were compared between the two groups.ResultsThe length of hospital stay [median (lower quartile, upper quartile): 8 (7, 11) vs. 8 (7, 12) d] and the hospitalization expenses [median (lower quartile, upper quartile): 7380.50 (6401.86, 8789.21) vs. 8167.00 (6816.50, 10044.50) yuan] were less in the pathway group than those in the control group, the incidences of postoperative macroscopic haematuria (1.52% vs. 6.97%) and perirenal hematoma (2.61% vs. 5.02%) were lower in the pathway group than those in the control group, the management enrollment rate of chronic kidney disease patients was higher in the pathway group than that in the control group (26.09% vs. 6.16%), and the differences between the two groups were statistically significant (P<0.05). The differences in the incidences of acute urinary retention (8.26% vs. 11.18%) and postoperative postural hypotension (0.00% vs. 0.81%) between the two groups were not statistically significant (P>0.05).ConclusionThe application of clinical nursing pathway in percutaneous renal needle biopsy can effectively reduce the length of hospital stay and hospitalization expenses, and improve the management enrollment rate of chronic kidney disease patients.
Objective To evaluate the diagnostic yield and safety of two biopsy methods, electromagnetic navigational bronchoscopy (ENB) and transthoracic needle biopsy (TTNB), in peripheral pulmonary lesions. To select a low-risk and high-benefit biopsy method based on the clinical characteristics of the lesions and patients. Methods A retrospective analysis was conducted on inpatients who underwent ENB and/or TTNB for peripheral pulmonary lesions in Huadong Hospital Affiliated to Fudan University. Propensity score matching was used to compare the diagnostic yield and safety of the two biopsy methods. Results A total of 126 patients were included in the ENB group, and 104 patients in the TTNB group. After propensity score matching, 83 matched pairs were obtained. The TTNB group exhibited a significantly higher diagnostic yield compared with the ENB group (90.4% vs. 48.2%, P<0.001), but it was also associated with a higher incidence of pneumothorax (1.2% vs. 21.7%, P<0.001). In the ENB group, the diagnostic efficacy was correlated with lesion diameter (P<0.001, OR=0.183, 95%CI 0.071 - 0.470), but there was no statistically significant difference in the diagnostic yield among different lung segments (P>0.05). In the TTNB group, lesion characteristics did not significantly affect the diagnostic yield, but a lesion diameter ≤30 mm (P=0.019, OR=5.359, 95%CI 1.320 - 21.753) and a distance from the pleura ≥20mm (P=0.030, OR=6.399, 95%CI 1.192 - 34.360) increased the risk of pneumothorax. When stratified based on lesion and patient blood characteristics, no significant difference was found in the diagnostic yield between the two groups for characteristics such as left upper lobe (P=0.195), right middle lobe (P=0.333), solid with cavity (P=0.567), or abnormal serum white blood cell count (P=0.077). However, the incidence of pneumothorax in the TTNB group was higher than that in the ENB group. Conclusions The diagnostic yield of ENB is affected by the size of the lesion, while the incidence of pneumothorax in TTNB is influenced by both lesion size and distance from the pleura. In cases with lesions located in the left upper lobe, right middle lobe, solid with cavity, or with abnormal serum white blood cell count, selecting ENB for biopsy is considered preferable to TTNB.
ObjectiveTo explore the diagnostic value of CT-guided percutaneous needle aspiration biopsy (PTNB) for ground-glass opacity (GGO) pulmonary lesions. MethodsA retrospective design was used to collect clinical data of patients with GGO lesions admitted in the Affiliated Hospital of North Sichuan Medical College between Jan. 2009 to Jan 2015. Patients were divided into groups according the lesion size (≤10 mm, 10-20 mm,≥20 mm), length of needle path (≤5 cm, 5-9 cm,≥9 cm) and percentage of GGO component (50%-90%, >90%), respectively. The total and subgroups of sensitivity, specificity, and diagnostic accuracy of CT guided PTNB for diagnosing GGO were calculated and the differences among subgroups were compared using Fisher's exact test. Statistical analysis was conducted by using SPSS 17.0 software. ResultsA total of 60 patients involving 48 malignant and 12 benign lesions were included. The total sensitivity, specificity, and accuracy of CT guided PTNB for diagnosing GGO were 87.5%, 100% and 90%, respectively. There were no significant differences among the subgroups based on the lesion size, length of needle path, and percentage of GGO component (all P values >0.05). ConclusionCT-guided PTNB can be used as one of the diagnostic modalities for lung GGO lesions with a moderate diagnostic value.
ObjectiveTo evaluate the diagnostic value of BRAFV600E mutation test in high-risk thyroid nodules with easily underdiagnosed fine-needle aspiration biopsy (FNAB) results.MethodsRetrospectively collected 122 cases of thyroid nodule who treated in the Hebei Petrochina Central Hospital between January 2017 and December 2018, all the cases admitted preoperative ultrasound and FNAB detection. All of the patients had the non-positive cytological results of FNAB and the high-risk features of ultrasound. Contrasted the postoperative pathological coincidence rate of combination of FNAB and BRAFV600E test with FNAB alone.ResultsThe BRAFV600E mutation rate was 27.0% (33/122). The positive rate of BRAFV600E mutation increased with the increase of ultrasound thyroid imaging reporting and data system(TI-RADS) grade (P<0.05), which was independent of patients’ age, gender, number of nodules, diameter of nodules, and FNAB results (P>0.05). The coincidence rate of FNAB combined with BRAFV600E mutation detection was higher than that of FNAB alone ［86.9% (106/122) vs. 69.7% (85/122), P<0.05).ConclusionsThe BRAFV600E mutation test can detect papillary thyroid carcinoma that might be missed by FNAB. We recommend that FNAB should be routinely accompanied by the BRAFV600E mutation test in the high-risk thyroid nodules.
ObjectiveTo systematically review the diagnostic accuracy of C-arm cone-beam CT (CBCT)-guided percutaneous transthoracic needle biopsy (PTNB) for lung nodules. MethodsWe electronically searched databases including PubMed, EMbase, EBSCO, Ovid, CBM, VIP, WanFang Data and CNKI from inception to Feb 28th, 2015, to collect diagnostic studies of CBCT-guided PTNB for lung nodules. Two reviewers independently screened literature, extracted data and assessed the methodological quality of included studies by QUADAS-1 tool. Then, meta-analysis was performed by Stata 12.0 and Meta-DiSc 1.4 softwares for calculating pooled sensitivity (Sen), specificity (Spe), positive likelihood ration (+LR), negative likelihood ration (-LR), and diagnostic odds ratio (DOR), drawing summary receiver operating characteristic (SROC) curve and estimating area under the curve (AUC). ResultsA total of 9 studies involving 1 815 patients were included. The results of meta-analysis showed that the pooled Sen, Spe, +LR,-LR, and DOR were 0.95 (95%CI 0.92 to 0.96), 1.00 (95%CI 0.66 to 1.00), 2 076.58 (95%CI 1.8 to 2.3e+0.6), 0.05 (95%CI 0.04 to 0.08), and 39 443.88 (95%CI 30.53 to 5.1e+0.7), respectively. The AUC of SROC was 0.97 (95%CI 0.95 to 0.98). ConclusionCBCT-guided PTNB can be used as one of the primary examination approaches for lung nodules with relatively high diagnostic accuracy. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
