Meta-Analysis Review
Core needle biopsy (CNB) of salivary gland lesions is a relatively new technique that may offer benefits for diagnosis of the lesions. We conducted a systematic literature review to identify studies published between January 1, 1985, and March 15, 2011. Summary estimates of sensitivity and specificity were obtained by using a summary receiver-operating characteristic (SROC) curve. Study quality was assessed by using the QUADAS survey. We identified 5 studies (277 cases) for inclusion. The area under the SROC for CNB was 1.00 (95% confidence interval [CI], 0.99-1.00). Based on histologically verified cases, the sensitivity of CNB is 0.92 (95% CI, 0.77-0.98) and the specificity is 1.00 (95% CI, 0.76-1.00). We conclude that CNB has high accuracy and a low (1.2%) inadequacy rate. CNB is more accurate than fine-needle aspiration, at least in some settings, but the best selection of which test to use for an individual patient and setting remains to be defined.

Meta-Analysis Review
Addition of intrarectal local analgesia to periprostatic nerve block improves pain control for transrectal ultrasonography-guided prostate biopsy: a systematic review and meta-analysis.
OBJECTIVES
To evaluate the efficacy and safety of combined intrarectal local analgesia and periprostatic nerve block versus periprostatic nerve block alone for pain control during transrectal ultrasound-guided prostate biopsy.
METHODS
We comprehensively searched PubMed, Embase and the Cochrane Library trials. Studies comparing the two techniques were identified and pooled for cumulative analysis. The outcome measurements included visual pain scales of three consecutive procedures of transrectal ultrasound-guided prostate biopsy, as well as short-term postoperative complication rates.
RESULTS
There were 18 studies that were finally eligible for the quantitative analysis involving 2076 participants. Combined modalities significantly reduced the pain associated with probe manipulation (weighted mean difference -2.06, 95% confidence interval -2.77 to -1.35, P < 0.001), anesthesia infiltration (weighted mean difference -1.45, 95% confidence interval -2.20 to -0.70, P < 0.001) and needle biopsy (weighted mean difference -0.55, 95% confidence interval -0.76 to -0.34, P < 0.001). Subgroup analyses assessing different local analgesics showed that local anesthetics are generally more effective than myorelaxant and non-steroidal anti-inflammatory drugs. Lidocaine-prilocaine cream proved the most effective in pain control regardless of the origin of pain. No significant difference of short-term postoperative complications (fever, dysuria, acute urinary retention, hematuria, hematospermia and rectal bleeding) was found between the two techniques. The only side-effect associated with local analgesics was headache reported in studies using glyceryl trinitrate ointment.
CONCLUSIONS
Combined modalities show better analgesic efficacy than periprostatic nerve block alone for transrectal ultrasound-guided prostate biopsy without increased morbidities. Among the various local analgesics, lidocaine-prilocaine cream seems to offer the best overall efficacy.

Comparative Study Meta-Analysis Review
OBJECTIVE
The primary objective was to quantify and compare the accuracy and failure rates of directional vacuum assisted biopsy (DVAB) and core needle biopsy (CNB) when used under stereotactic (ST) guidance to biopsy suspicious breast lesions identified with screening mammography.
METHODS
We performed a systematic review of the literature published from January 1996 to July 2004, reporting all-comers populations in Western-style health care systems (i.e., North America, Europe, Australia or New Zealand), referred after screening mammography for breast biopsy using DVAB or CNB under ST guidance. Meta-analyses were conducted for DVAB and CNB, using open surgical biopsy and/or long-term clinical and/or mammogram follow-up as the diagnostic reference standard. The main outcomes of interest were those of greatest clinical relevance, i.e., miss rates and underestimation rates for malignancy. Also, technical failure rate and non-diagnostic rate were assessed for each biopsy method.
RESULTS
Thirty-five studies qualified for the review. There were 12 studies with a DVAB group (n=5,119 patients), and 25 studies with a CNB group (n=6,236). There were no studies including both a DVAB and a CNB group, thus precluding any direct, within-study comparisons of accuracy. Overall agreement rate between DVAB and the reference standard was 97.3%, and between CNB and the reference standard, 93.5%. The frequency of technical failures with CNB was slightly higher than DVAB (5.7 vs. 1.5%), as was the frequency of non-diagnostic samples (2.1 vs. 0%). Of the non-diagnostic CNB samples, 23% were subsequently found to be malignant on reference standard. In multivariate analyses using four covariates (procedure type, geographic location, reference standard, and patient position), there were no significant predictors of agreement rates, but some variables were significant predictors of miss rates. For benign to malignant upgrades, study location was a significant predictor, with more upgrades in non-NA locations. For atypia to malignant upgrades, the type of procedure was a significant predictor, with more underestimations in CNB studies.
CONCLUSION
The best available evidence suggests that, in screening populations referred for minimally invasive breast biopsy biopsy requiring ST guidance, DVAB may provide lower miss and underestimation rates for clinically relevant diagnoses than does CNB.

Meta-Analysis Review
PURPOSE
To systematically appraise and summarize the available evidence about the diagnostic accuracy of ultrasound-guided fine needle aspiration biopsy (USFNA) for thyroid malignancy, and to explore the integration of these estimates with the probability of thyroid malignancy before USFNA.
METHODS
A comprehensive search of multiple databases from each database's inception to August 2014 was performed. Eligible studies included those that evaluated patients with thyroid nodules who underwent USFNA and subsequent evaluation by histopathology or long-term follow-up.
RESULTS
We identified 32 studies at moderate risk of bias evaluating the USFNA diagnostic characteristics for the diagnosis of thyroid malignancy. Results were imprecise and inconsistent across trials. The pooled likelihood ratio (LR) of thyroid malignancy for a benign USFNA result was 0.09 (95 % CI 0.06, 0.14; I (2) = 33 %), whereas the pooled LR for a malignant result was 197 (95 % CI, 68, 569; I (2) = 77 %). In the case of a suspicious for follicular neoplasm result, the pooled LR for malignancy was 0.6 (95 % CI, 0.4, 1.0; I (2) = 84 %) and 8.3 (95 % CI, 3.6, 19.2; I (2) = 89) for a result of suspicious for malignancy.
CONCLUSION
The available evidence regarding the diagnostic accuracy of USFNA warrants only limited confidence due to risk of bias, imprecision, and inconsistency. However, some USFNA results (benign, malignant) are likely very helpful, by significantly changing the pre-test probability of thyroid cancer.

Detailed fine needle aspiration cytopathology findings of noninvasive follicular thyroid neoplasm with papillary-like nuclear features with nuclear grading correlated to that of biopsy and Bethesda category and systematic review.
BACKGROUND
Noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) poses diagnostic challenge in fine needle aspiration cytopathology (FNAC). We aimed first to document our FNAC Bethesda categories (BCs) for all of our NIFTPs and compare our findings with those in the literature with series containing at least 14 cases each.
METHODS
Cases with final histopathological diagnoses of NIFTP and their preoperative FNAC were retrieved from 2006 to 2022 and our cytopathological BCs were documented. Then the slides were re-reviewed in a blinded manner for detailed classification and the results of both the BCs and blinded reclassification were compared with series in the literature for both BCs and detailed cytopathological review of the cases.
RESULTS
Thyroid FNACs of 43 out of 86 patients with final NIFTP diagnoses were obtained. Females composed 72.1% (F/M: 31/12); mean age and mean tumor diameter was 47.6 (19-72 years) and 23.4 mm (7-60 mm), respectively. Totally 81.4% (35/43) were classified in the "indeterminate" diagnostic categories; namely 44.2% (19/43) were reported as atypia of undetermined significance (AUS; BC III), 20.9% (9/43) were follicular neoplasm (FN; BC IV), and 16.3% (7/43) were suspicious for malignancy (SM; BC V). No patient was diagnosed as positive for malignancy (BC VI), preoperatively. Detailed cytomorphologic reevaluation revealed heterogeneous cytopathologic findings and nuclear grade (especially nuclear enlargement, membrane irregularity and elongation) significantly increased with respect to BCs. Systematic review confirmed extremely heterogeneous cytomorphologic nature of NIFTP.
CONCLUSIONS
NIFTPs were categorized most frequently as AUS, followed by FN and SM on FNAC. Our re-review were not able to specify features solely unique to NIFTP alone but may distinguish these cases from classic papillary thyroid carcinoma.

Meta-Analysis
BACKGROUND
Controversies exist regarding the biopsy technique of choice for the accurate diagnosis of soft-tissue sarcoma (STS). The objective of this systematic review and meta-analysis was to compare the diagnostic accuracy of core needle biopsy (CNB) versus incisional biopsy (IB) in STS with reference to the final histopathological result.
METHODS
Studies regarding the diagnostic accuracy of CNB and IB in detecting STS were searched systematically in the MEDLINE and EMBASE databases. Estimates of sensitivity and specificity with associated 95% CIs for diagnostic accuracy were calculated. The risk of bias was assessed using the Quality Assessment of Diagnostic Accuracy Studies version 2 (QUADAS-2).
RESULTS
A total of 17 studies comprising 2680 patients who underwent 1582 CNBs and 241 IBs with subsequent tumor resection met the inclusion criteria. The sensitivity and specificity of CNB and IB to detect the dignity of lesions were 97% (95% CI, 95%-98%) and 99% (95% CI, 97%-99%), respectively, and 96% (95% CI, 92%-99%) and 100% (95% CI, 94%-100%), respectively. Estimates of the sensitivity and specificity of CNB and IB to detect the STS histotype were 88% (95% CI, 86%-90%) and 77% (95% CI, 72%-81%), respectively, and 93% (95% CI, 87%-97%) and 65% (95% CI, 49%-78%), respectively. Patients who underwent CNB had a significantly reduced risk of complications compared with patients who underwent IB (risk ratio, 0.14; 95% CI, 0.03-0.56 [P ≤ .01). Quality assessment of studies revealed a high risk of bias.
CONCLUSIONS
CNB has high accuracy in diagnosing the dignity of lesions and STS histotype in patients with suspected STS with fewer complications compared with IB. Therefore, CNB should be regarded as the primary biopsy technique.

Meta-Analysis
OBJECTIVE
We conducted a systematic review and meta-analysis of the tissue adequacy and complication rates of percutaneous transthoracic needle biopsy (PTNB) for molecular analysis in patients with non-small cell lung cancer (NSCLC).
MATERIALS AND METHODS
We performed a literature search of the OVID-MEDLINE and Embase databases to identify original studies on the tissue adequacy and complication rates of PTNB for molecular analysis in patients with NSCLC published between January 2005 and January 2020. Inverse variance and random-effects models were used to evaluate and acquire meta-analytic estimates of the outcomes. To explore heterogeneity across the studies, univariable and multivariable meta-regression analyses were performed.
RESULTS
A total of 21 studies with 2232 biopsies (initial biopsy, 8 studies; rebiopsy after therapy, 13 studies) were included. The pooled rates of tissue adequacy and complications were 89.3% (95% confidence interval [CI]: 85.6%-92.6%; I² = 0.81) and 17.3% (95% CI: 12.1%-23.1%; I² = 0.89), respectively. These rates were 93.5% and 22.2% for the initial biopsies and 86.2% and 16.8% for the rebiopsies, respectively. Severe complications, including pneumothorax requiring chest tube placement and massive hemoptysis, occurred in 0.7% of the cases (95% CI: 0%-2.2%; I² = 0.67). Multivariable meta-regression analysis showed that the tissue adequacy rate was not significantly lower in studies on rebiopsies ( = 0.058). The complication rate was significantly higher in studies that preferentially included older adults ( = 0.001).
CONCLUSION
PTNB demonstrated an average tissue adequacy rate of 89.3% for molecular analysis in patients with NSCLC, with a complication rate of 17.3%. PTNB is a generally safe and effective diagnostic procedure for obtaining tissue samples for molecular analysis in NSCLC. Rebiopsy may be performed actively with an acceptable risk of complications if clinically required.

Review
BACKGROUND
Glomangiopericytoma belongs to the category of borderline/low-malignant-potential tumors of the sinonasal tract, but no studies about prognosis have been reported.
METHODS
To define the characteristics of glomangiopericytoma and to identify its prognostic factors, a systematic review was performed. A total of 337 cases of glomangiopericytomas were analyzed.
RESULTS
Patients with glomangiopericytoma demonstrating resection margin involvement and receiving radiotherapy/chemotherapy had a significantly worse disease-free survival time (P = .014 and .006, respectively). Patients with glomangiopericytoma had a tendency toward longer overall survival when they were diagnosed at a younger age (≤60 years; P = .001), did not demonstrate marginal involvement (P = .032), recurrence/metastasis (P = .002), or radiotherapy/chemotherapy (P = .010), and had a right-sided tumor (P < .001), actin-immunopositivity (P < .001), and CD34-/BCL2-immunonegativities (P = .002 and .019, respectively). By multivariate analysis, actin (P < .001) and CD34 (P = .002) immunostaining were significantly related to the overall survival of patients with glomangiopericytoma.
CONCLUSION
Actin and CD34 immunostaining could be used as independent prognostic indicators of glomangiopericytomas.

Meta-Analysis
PURPOSE
Although ductal carcinoma in situ (DCIS) seldom involves lymph nodes, some patients may upstage to invasive disease, thus requiring a second surgery for sentinel lymph node (SLN) biopsy (SLNB). However, the indications of SLNB remain inconclusive and clinical trials are rarely available. Our aim is to systematically review the real-world data to evaluate whether SLNB is precisely applied in patients with a high risk of upstaging from DCIS to invasive carcinoma.
METHODS
PubMed, EMBASE, and Cochrane library databases were searched. Prospective and retrospective cohort studies that evaluated the pathological outcomes of SLNB and the upstaging rate in women with DCIS were included. The primary outcomes were the upstaging and SLN-positive rates of patients initially diagnosed as having DCIS. We analyzed factors, namely biopsy methods, clinical presentations, histological patterns, and hormone receptor status, that potentially indicate nodal involvement risk.
RESULTS
We retrieved 43 prospective and 69 retrospective studies including 44,001 patients. The pooled estimates of upstaging and SLN-positive rates were 25.8% (95% confidence interval [CI]: 0.230-0.286) and 4.9% (95% CI: 0.042-0.055), respectively. In subgroup analysis, the upstaging rate was significantly higher in patients with estrogen receptor-negative status, palpable mass, tumor size >2 cm on imaging, and high-nuclear grade and those who received a preoperative diagnosis through core needle biopsy.
CONCLUSION
The upstaging and SLN-positive rates of DCIS were 25.8% and 4.9%, respectively. By selecting patients with high risk DCIS, surgeons may increase the precision of and reduce the excess and incomplete treatment rates of SLNB.

Review
PURPOSE
More literatures regarding radiocolloid-based dynamic sentinel lymph node biopsy (DSNB) in penile cancer with clinically negative groin (cN0) have been published since previous meta-analysis in 2012. This updated meta-analysis was to assess the accuracy of the procedure in penile cancer with cN0 disease and explore its relative factors on the basis of current evidences.
MATERIALS AND METHODS
We performed a review of PubMed, Ovid/Embase, and the Cochrane Library in March 2016 according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement. Study quality was evaluated by the use of the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2). A random effects model was used for statistical pooling. Publication bias was evaluated by the use of funnel plot and Egger's test. Meta-regression, subgroup and sensitivity analysis were conducted to explore the sources of heterogeneity.
RESULTS
A total of 27 articles were included. Two articles had two different cohorts and each cohort was considered a separate study. Overall 29 studies were used for sensitivity and negative predictive value (NPV) meta-analysis. The pooled sensitivity and NPV was 88 % (95 % CI 84-90 %) and 99 % (98-99 %), respectively. Meta-regression and subgroup analysis revealed that the use of preoperative ultrasonic scan (USS) ± fine-needle aspiration cytology (FNAC), surgical exploration of wound for suspicious lymph nodes (LN), immunohistochemistry (IHC) and extensive experience were significantly associated with the improved sensitivity of DSNB.
CONCLUSIONS
Radiocolloid-based DSNB is a promising staging modality to detect inguinal micrometastasis in penile cancer without clinically positive inguinal LN. Preoperative USS ± FNAC and surgical exploration are effective supplements to exclude potentially clinical involvement, and IHC makes the diagnosis of occult metastasis in SLN more likely. The multidisciplinary and multistep procedure should be performed by skilled teams in specialized centers.
