Review
BACKGROUND
Because less-invasive techniques can obviate the need for brain biopsy in the diagnosis of primary central nervous system lymphoma (PCNSL), it is common practice to wait for a thorough initial work-up, which may delay treatment. We conducted a systematic review and reviewed our own series of patients to define the role of LP and early brain biopsy in the diagnosis of PCNSL.
METHODS
Our study was divided into 2 main sections: 1) systematic review assessing the sensitivity of cerebrospinal fluid (CSF) analysis on the diagnosis of PCNSL, and 2) a retrospective, single-center patient series assessing the diagnostic accuracy and safety of early biopsy in immunocompetent PCNSL patients treated at our institution from 2012 to 2018.
RESULTS
Our systematic review identified 1481 patients with PCNSL. A preoperative LP obviated surgery in 7.4% of cases. Brain biopsy was the preferred method of diagnosis in 95% of patients followed by CSF (3.1%). In our institutional series, brain biopsy was diagnostic in 92.3% of cases (24/26) with 2 cases that required a second procedure for diagnosis. Perioperative morbidity was noted in 7.6% of cases (n = 2) due to hemorrhages after stereotactic brain biopsy that improved at follow-up.
CONCLUSIONS
The diagnostic yield of CSF analyses for PCNSL in immunocompetent patients remains exceedingly low. Our institutional series demonstrates that early biopsy for PCNSL is safe and accurate, and may avert protracted work-ups. We conclude that performing an early brain biopsy in a suspected case of PCNSL is a valid, safe option to minimize diagnostic delay.

Meta-Analysis
BACKGROUND
Percutaneous liver biopsy is the gold standard test for the assessment of liver disease. In patients with coagulopathy, ascites, post-transplantation, and hypervascular tumors, biopsy is associated with increased risk of adverse events (AEs). Transjugular liver biopsy (TJLB) is recommended in these conditions but is expensive and unavailable at many centers. Plugged liver biopsy (PLB) provides an alternate diagnostic modality in these high-risk cases.
PURPOSE
To analyze the pooled diagnostic outcome and safety of PLB in high-risk cases.
MATERIAL AND METHODS
A literature search of various databases from January 1990 to July 2022 was conducted for studies evaluating the outcome of PLB in high-risk cases. The primary outcomes were pooled sample adequacy and AEs. Pooled event rates across studies were expressed with summative statistics.
RESULTS
A total of 17 studies (2329 patients) were included in the meta-analysis. The pooled proportion of sample adequacy was 98.9% (95% confidence interval [CI]=98.2-99.6). Severe AEs, major bleeding, and minor AEs were seen in 0.7% (95% CI=0.1-1.3), 0.4% (95% CI=0.1-0.8), and 11.5% (95% CI=2.4-20.6) of the patients. There was only one reported mortality, giving a pooled incidence of 0.0002% (95% CI=0.0-0.0038). Compared to TJLB (5 studies, n = 336), there was no difference in either sample adequacy (odds ratio [OR]=2.34, 95% CI=0.83-6.58) or risk of serious AEs (OR=0.47, 95% CI=0.173-1.31).
CONCLUSION
PLB can be safely performed on patients with coagulopathy and/or ascites with high sample adequacy rates and low incidence of AEs and mortality.

Meta-Analysis Review
BACKGROUND
Core-needle biopsy (CNB) has occasionally been used in the work-up of head and neck lesions. However, no systematic review of this simple, minimally invasive method has yet been performed.
METHODS
A systematic review of the literature and meta-analysis of data extracted from 16 included studies were performed. A total of 1291 cervical lesions in 1267 patients were examined by CNB. This resulted in 1232 adequate samples, from which 554 were subsequently confirmed by excisional biopsy.
RESULTS
CNB was able to identify true neoplasms and detect malignancy in head and neck lesions with an overall accuracy of 94% and 96%, respectively, even though there was a significant difference between the histologically verified and all adequate samples. CNB provided a correct specific diagnosis in 87% of cases without major complications and achieved a higher accuracy than that of fine-needle aspiration in detecting malignancy.
CONCLUSIONS
This meta-analysis confirms that CNB is an excellent method in the assessment of salivary gland lesions and lymphadenopathies inclusive of malignant lymphoma, but it is not ideal for evaluating thyroid lesions.

Review
BACKGROUND
Systemic arterial gas embolism (SAGE) is a rare yet serious and underrecognized complication of bronchoscopic procedures. A recent case of presumed SAGE after transbronchial needle aspiration prompted a systematic literature review of SAGE after biopsy procedures during flexible bronchoscopy.
METHODS
We performed a systematic database search for case reports and case series pertaining to SAGE after bronchoscopic lung biopsy; reports or series involving only bronchoscopic laser therapy or argon plasma coagulation (APC) were excluded. Patient data were extracted directly from published reports.
RESULTS
A total of 29 unique patient reports were assessed for patient demographics, specifics of the procedure, clinical manifestations, diagnostic findings, and clinical outcomes. Cases of SAGE occurred after multiple types of bronchoscopic biopsy and under both positive and negative pressure ventilation. The most common clinical findings were neurologic, followed by cardiac manifestations; temporal patterns included acute onset of cardiac or neurologic emergencies immediately after biopsy, or delayed awakening post-procedure. There was a high mortality rate among cases (28%), with residual neurologic deficits also common (24%).
DISCUSSION
SAGE is an underrecognized but severe adverse effect of bronchoscopic lung biopsy, which often presents with acute coronary or cerebral ischemia or delayed awakening from sedation. It is important for all physicians who perform bronchoscopic biopsies to be aware of the clinical manifestations and therapeutic management of SAGE in order to mitigate morbidity and mortality among patients undergoing these procedures.

Comparative Study Meta-Analysis Review
Magnetic resonance imaging-targeted biopsy may enhance the diagnostic accuracy of significant prostate cancer detection compared to standard transrectal ultrasound-guided biopsy: a systematic review and meta-analysis.
CONTEXT
Multiparametric magnetic resonance imaging (MRI) of the prostate may improve the diagnostic accuracy of prostate cancer detection in MRI-targeted biopsy (MRI-TBx) in comparison to transrectal ultrasound-guided biopsy (TRUS-Bx).
OBJECTIVE
Systematic review and meta-analysis of evidence regarding the diagnostic benefits of MRI-TBx versus TRUS-Bx in detection of overall prostate cancer (primary objective) and significant/insignificant prostate cancer (secondary objective).
EVIDENCE ACQUISITION
A systematic review of Embase, Medline, Web of Science, Scopus, PubMed, Cinahl, and the Cochrane library was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Identified reports were critically appraised according to the Quality Assessment of Diagnostic Accuracy Studies criteria. Only men with a positive MRI were included.
EVIDENCE SYNTHESIS
The reports we included (16 studies) used both MRI-TBx and TRUS-Bx for prostate cancer detection. A cumulative total of 1926 men with positive MRI were included, with prostate cancer prevalence of 59%. MRI-TBx and TRUS-Bx did not significantly differ in overall prostate cancer detection (sensitivity 0.85, 95% confidence interval [CI] 0.80-0.89, and 0.81, 95% CI 0.70-0.88, respectively). MRI-TBx had a higher rate of detection of significant prostate cancer compared to TRUS-Bx (sensitivity 0.91, 95% CI 0.87-0.94 vs 0.76, 95% CI 0.64-0.84) and a lower rate of detection of insignificant prostate cancer (sensitivity 0.44, 95% CI 0.26-0.64 vs 0.83, 95% confidence interval 0.77-0.87). Subgroup analysis revealed an improvement in significant prostate cancer detection by MRI-TBx in men with previous negative biopsy, rather than in men with initial biopsy (relative sensitivity 1.54, 95% CI 1.05-2.57 vs 1.10, 95% CI 1.00-1.22). Because of underlying methodological flaws of MRI-TBx, the comparison of MRI-TBx and TRUS-Bx needs to be regarded with caution.
CONCLUSIONS
In men with clinical suspicion of prostate cancer and a subsequent positive MRI, MRI-TBx and TRUS-Bx did not differ in overall prostate cancer detection. However, MRI-TBx had a higher rate of detection of significant prostate cancer and a lower rate of detection of insignificant prostate cancer compared with TRUS-Bx.
PATIENT SUMMARY
We reviewed recent advances in magnetic resonance imaging (MRI) for guidance and targeting of prostate biopsy for prostate cancer detection. We found evidence to suggest that MRI-guided targeted biopsy benefits the diagnosis of prostate cancer.

AIMS
The biomarkers oestrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2) are routinely measured in patients with breast cancer with international consensus on how they should be interpreted. There is evidence to support use of other biomarkers to give more detailed predictive and prognostic information. Ki-67 is one example, and measures the proliferative activity of cancer cells. It is important that this can be performed at diagnosis of breast cancer for patients who do not have initial surgical treatment (mainly older women) and those receiving neoadjuvant therapies.
METHODS AND RESULTS
A systematic review was performed to assess concordance of measurement of Ki-67 between core needle biopsy (CNB) samples and surgical excision (SE) samples in patients with invasive breast cancer. MEDLINE and Embase databases were searched. Studies were eligible if performed within the last 10 years; included quantitative measurement of Ki-67 in both CNB and SE samples with no prior breast cancer treatment; measured concordance between two samples; and had full text available. A total of 22 studies, including 5982 paired CNB and SE samples on which Ki-67 was measured, were appraised. Overall, there appeared to be concordance; however, reliability was unclear. Where given, the Cohen's kappa coefficient (κ) of correlation between samples ranged from 0.261 to 0.712. The concordance rate between CNB and SE where measured as a percentage had a range from 70.3 to 92.7% CONCLUSIONS: Assessment of level of concordance of Ki-67 between CNB and SE samples is hampered by different methodologies. International consensus on Ki-67 measurement is urgently needed.

Meta-Analysis Review
BACKGROUND
Transjugular liver biopsy (TJLB) procedurally samples liver tissue through the internal jugular vein. It is indicated in the presence of coagulopathies and/or ascites.
AIMS
This meta-analysis aimed to assess the safety and efficacy of TJLB in children.
METHODS
A literature search of several databases was conducted from inception to August 2022. Eligible studies reported pediatric patients (< 18 years old) who underwent TJLB. The pooled proportion was analyzed using a random-effects model. This review was registered in PROSPERO (CRD42022354421).
RESULTS
From 921 initial studies screened, eight met the eligibility criteria, with a total of 361 pediatric patients who underwent 374 TJLBs. All eight studies reported pooled rates of technical success at 99.1% (95% CI 0.982, 1.001; I = 0%) and histological adequacy of sampling at 97.5% (95% CI 0.954, 0.995; I = 27.66%). A total of 49 complications were reported across six studies, the most common being bleeding from the entry site (38.78%), fevers for less than 24 h (12.24%), red blood cells transfusion requirement (10.2%), supraventricular tachycardia (8.16%), and pain requiring analgesia (8.16%).
CONCLUSION
Pediatric TJLB demonstrates high rates of technical success and adequate liver core biopsy samples, with a low rate of complications. These results suggest that TJLB is an effective method for diagnostic yield and postprocedural outcomes, especially in patients with preexisting coagulopathies and ascites where percutaneous liver biopsy is contraindicated. Additional studies evaluating larger groups of pediatric patients may provide further support for the use of TJLB in this population.

Meta-Analysis Review
BACKGROUND
Image-guided biopsy is routinely conducted in patients with suspected discitis, though the sensitivity reported in the literature ranges widely.
PURPOSE
We applied a systematic review and meta-analysis to estimate the yield of image-guided biopsy for infectious discitis.
DATA SOURCES
We performed a literature search of 4 data bases: PubMed, Cochrane CENTRAL Register of Controlled Trials, Embase.com, and Scopus from data base inception to March 2016.
STUDY SELECTION
A screen of 1814 articles identified 88 potentially relevant articles. Data were extracted for 33 articles, which were eligible if they were peer-reviewed publications of patients with clinical suspicion of discitis who underwent image-guided biopsy.
DATA ANALYSIS
Patients with positive cultures out of total image-guided biopsy procedures were pooled to estimate yield with 95% confidence intervals. Hypothesis testing was performed with an inverse variance method after logit transformation.
DATA SYNTHESIS
Image-guided biopsy has a yield of approximately 48% (793/1763), which is significantly lower than the open surgical biopsy yield of 76% (152/201; < .01). Biopsy in patients with prior antibiotic exposure had a yield of 32% (106/346), which was not significantly different from the yield of 43% (336/813; = .08) in patients without prior antibiotic exposure.
LIMITATIONS
The conclusions of this meta-analysis are primarily limited by the heterogeneity of the included studies.
CONCLUSIONS
Image-guided biopsy has a moderate yield for the diagnosis of infectious discitis, which is significantly lower than the yield of open surgical biopsy. This yield is not significantly affected by prior antibiotic use.

Meta-Analysis
BACKGROUND
Both anaplastic thyroid carcinoma (ATC) and thyroid lymphoma (TL) clinically present as rapidly enlarging neck masses. Unfortunately, in this situation, like in any other thyroid swelling, a routine fine-needle aspiration (FNA) cytology is the first and only diagnostic test performed at the initial contact in the average thyroid practice. FNA, however, has a low sensitivity in diagnosing ATC and TL, and by the time the often "inconclusive" result is known, precious time has evolved, before going for core-needle biopsy (CNB) or incisional biopsy (IB) as the natural next diagnostic steps.
OBJECTIVES
To determine the diagnostic value of CNB in the clinical setting of a rapidly enlarging thyroid mass, a systematic review and meta-analysis of the available data on CNB reliability in the differential diagnosis of ATC and TL.
METHODS
A PubMed, Embase and Web of Science database search was performed on June 23th 2021. Population of interest comprised patients who underwent CNB for clinical or ultrasonographical suspicion of ATC or TL, patients with a final diagnosis of ATC or TL after CNB, or after IB following CNB.
RESULTS
From a total of 17 studies, 166 patients were included. One hundred and thirty-six were diagnosed as TL and 14 as ATC following CNB. CNB, with a sensitivity and positive predictive value of 94,3% and 100% for TL and 80,1% and 100% for ATC respectively, proved to be superior to FNA (reported sensitivity for TL of 48% and for ATC of 61%). Furthermore, the need for additional diagnostic surgery after CNB was only 6.2% for TL and 17.6% for ATC.
CONCLUSIONS
Immediately performing CNB for a suspected diagnosis of ATC and TL in a rapidly enlarging thyroid mass is more appropriate and straightforward than a stepped diagnostic pathway using FNA first and awaiting the result before doing CNB.

Review
BACKGROUND
Bullous pemphigoid is an autoimmune disease that typically presents with tense bullae and severe pruritus. However, bullae can be lacking, a subtype termed nonbullous pemphigoid.
OBJECTIVE
To summarize the reported characteristics of nonbullous pemphigoid.
METHODS
The EMBASE and MEDLINE databases were searched using "nonbullous pemphigoid" and various synonyms. Case reports and series describing nonbullous pemphigoid were included.
RESULTS
The search identified 133 articles. After selection, 39 articles were included, presenting 132 cases. Erythematous, urticarial plaques (52.3%) and papules/nodules (20.5%) were the most reported clinical features. The mean age at presentation was 74.9 years. Histopathology was commonly nonspecific. Linear depositions of IgG and/or C3 along the basement membrane zone were found by direct immunofluorescence microscopy in 93.2%. Indirect immunofluorescence on salt-split skin was positive in 90.2%. The mean diagnostic delay was 22.6 months. A minority of patients (9.8%) developed bullae during the reported follow-up.
LIMITATIONS
Results are mainly based on case reports and small case series.
CONCLUSION
Nonbullous pemphigoid is an underdiagnosed variant of pemphigoid that most often does not evolve to bullous lesions and mimics other pruritic skin diseases. Greater awareness among physicians is needed to avoid delay in diagnosis.
