Comparative Study
BACKGROUND
Lung percutaneous needle biopsy (PNB) is routinely used to diagnose lung cancer. The most prevalent complications of PNB are pneumothorax and bleeding. Differences in characteristics of medical procedures between rural and urban hospitals are well known.
OBJECTIVES
To compare characteristics of patients and lesions between two hospitals and to evaluate whether lung PNB complications differ in rural vs. urban settings.
METHODS
The authors examined case records of 561 patients who underwent lung biopsy at two different medical centers in Israel: Tel Aviv Sourasky Medical Center (urban) and Barzilai Medical Center (rural). To evaluate the complication rates, the authors analyzed findings from chest X-ray performed 2 hours after biopsy and computed tomography (CT) images at the site of biopsy.
RESULTS
The study comprised 180 patients who underwent lung biopsy at Barzilai and 454 at Sourasky. The rate of pneumothorax did not differ between centers (12% at Barzilai and 19% at Sourasky, P = 0.08). Distance from pleura was positively correlated to pneumothorax occurrence in both centers; however, neither lesion size nor lesion locus was found to be a risk factor for pneumothorax. Mild bleeding at the biopsy site occurred equally at Barzilai and Sourasky (32% vs. 36%, P = 0.3, respectively). Furthermore, immediate CT post-biopsy at Barzilai showed 95% negative predictive value, showing that a CT scan performed immediately after lung biopsy cannot replace the routine follow-up chest X-ray in predicting iatrogenic pneumothorax.
CONCLUSIONS
CT-guided percutaneous lung biopsies are comparable between rural and urban hospitals regarding procedure characteristics and complication rates.

Dermatologists rely on skin biopsies to diagnose cutaneous tumors and rashes. Skin biopsy sites should be accurately identified with conventional anatomical site descriptors in the pathology request form. Reliance upon free-text entries to describe these biopsy sites is prone to user error and can cause medical misadventures such as wrong-site follow-up surgery. We sought to determine whether a smartphone application (RightSite) could improve the precision of biopsy site labeling. We conducted a prospective proof-of-concept study of 100 smartphone-assisted skin biopsy site identifiers with matched comparison to 100 historical controls. Student's t-test was used to identify significant differences in the precision of anatomic descriptors before and after adoption of the application. We found a 69% improvement in precision of anatomic site labeling with the RightSite smartphone application (P < 0.0001). These data show smartphone-assisted biopsy site labeling improves the precision of anatomic site descriptors. Integrating graphical user interfaces into the electronic health records system could improve health care by standardizing anatomic site nomenclature and site-specific descriptors.

BACKGROUND
Percutaneous needle biopsy of renal masses has been increasingly utilized to aid the diagnosis and guide management. It is generally considered as a safe procedure. However, tumor seeding along the needle tract, one of the complications, theoretically poses potential risk of tumor spread by seeded malignant cells. Prior studies on the frequency of needle tract seeding in renal tumor biopsies are limited and clinical significance of biopsy-associated tumor seeding remains largely controversial.
METHODS
Here we investigated the frequencies of biopsy needle tract tumor seeding at our institution by reviewing the histology of renal cell carcinoma nephrectomy specimens with a prior biopsy within the last seventeen years. Biopsy site changes were recognized as a combination of foreign body reaction, hemosiderin deposition, fibrosis and fat necrosis. The histologic evidence of needle tract tumor seeding was identified as clusters of tumor cells embedded in perinephric tissue spatially associated with the biopsy site. In addition, association between parameters of biopsy techniques and tumor seeding were investigated.
RESULTS
We observed needle tract tumor seeding to perinephric tissue in six out of ninety-eight (6 %) renal cell carcinoma cases including clear cell renal cell carcinoma, papillary renal cell carcinoma, chromophobe, and clear cell papillary renal cell carcinoma. The needle tract tumor seeding was exclusively observed in papillary renal cell carcinomas (6/28, 21 %) that were unifocal, small-sized (≤ 4 cm), confined to the kidney and had type 1 features. No recurrence or metastasis was observed in the papillary renal cell carcinoma cases with tumor seeding or the stage-matched cases without tumor seeding.
CONCLUSIONS
Our study demonstrated a higher than reported frequency of needle tract tumor seeding. Effective communication between pathologists and clinicians as well as documentation of tumor seeding is recommended. Further studies with a larger patient cohort and longer follow up to evaluate the impact of needle tract tumor seeding on long term prognosis are needed. This may also help reach a consensus on appropriate pathologic staging of renal cell carcinoma when the only site of perinephric fat invasion is within a biopsy needle tract.

We analyzed the intensity of pain at each site of systemic prostate biopsy (SBx) and compared the intensity of pain among magnetic resonance (MRI)-targeted transrectal biopsies according to the periprostatic nerve block (PNB) site. We collected data from 229 consecutive patients who had undergone MRI-targeted biopsy. Patients were stratified into two groups according to the site of PNB (base versus base and apex PNB). Pain was quantified at the following time points: probe insertion, injection at the prostate base, injection at the prostate apex, MRI cognitive biopsy (CBx), MRI/transrectal ultrasound fusion biopsy (FBx), SBx, and 15 min after biopsy. For all biopsy methods, the average pain were significantly higher in the base PNB group than in the base and apex PNB group (CBx, p < 0.001; FBx, p = 0.015; SBx, p < 0.001). In the base and apex PNB group, FBx was significantly more painful than SBx (p = 0.024). Overall, regardless of the PNB site, pain at the anterior sites was more than that at the posterior sites in FBx (p = 0.039). Base and apex PNB provided better overall pain control than base-only PNB in all biopsy methods. In the base and apex PNB group, FBx was more painful than CBx and SBx.

AIMS
Cardiac scintigraphy, a non-invasive technique for diagnosing ATTR cardiac amyloidosis, lacks specificity in patients with concomitant monoclonal gammopathy (up to 40% of cases). For these patients, amyloid type is often established by endomyocardial biopsy (EMB), which has clinical risk. This study aimed to investigate the frequency of ATTR in amyloid-positive tendon/synovium, urinary bladder, and prostate biopsies, sites for which prior biopsy specimens might exist for patients suspected of having cardiac amyloidosis, and, when available, determine the amyloid type concordance rate with other anatomic sites and provide clinical data regarding subsequent development of cardiac amyloidosis.
METHODS AND RESULTS
We queried our reference laboratory database of 19,298 amyloid specimens from myriad anatomic sites typed by mass spectrometry-based proteomics (LC-MS/MS) to investigate the frequency of ATTR amyloid in tendon/synovium, urinary bladder, and prostate. The amyloid type was ATTR in 104/138 (75.4%) tendon/synovium, 173/453 (38.0%) urinary bladder, and 27/81 (33.3%) prostate samples. Of 62 patients with available clinical data, 12 (19%) had bona fide ATTR cardiac amyloidosis prior to/concomitant with the non-cardiac site biopsy. Of the remaining 14 with follow-up, 8 developed bona fide and 2 probable cardiac amyloidosis; at last follow-up 4 had no evidence of cardiac amyloidosis. Fourteen of 16 patients (87.5%) for whom we typed both non-cardiac and cardiac sites had concordant amyloid types. There were 2 discordant cases (prostate = ASem1/heart = AL and urinary bladder = AL/heart = ATTR); only the latter is potentially clinically consequential.
CONCLUSIONS
In patients suspected of having cardiac amyloidosis based on cardiac scintigraphy, LC-MS/MS typing of Congophilic deposits in pre-existing biopsy specimens from non-cardiac sites may help establish the cardiac amyloid type, obviating the need for EMB. However, if the amyloid type identified in the non-cardiac site is not in keeping with other clinical features, then EMB for typing the cardiac amyloid might be indicated.

BACKGROUND & AIMS
Recent research has demonstrated biologic plausibility for iatrogenic tumor seeding via colonoscopy as a cause of metachronous colorectal cancers (CRC). This study evaluated the association between biopsy of non-tumor sites after CRC biopsy and risk of metachronous CRC in a large community-based health care organization.
METHODS
This was a retrospective case-control study of adults with an initial CRC diagnosed by colonoscopy between January 2006 and June 2018 who underwent curative resection. Cases developed a second primary (metachronous) CRC diagnosed 6 months to 4 years after the initial CRC, and were matched by age, sex, diagnosis of inflammatory bowel disease, race, and ethnicity with up to 5 controls without a second CRC diagnosis. The exposure was biopsy in the colonic segment of the metachronous CRC (or corresponding segment in controls) after tumor biopsy, ascertained with blinding to case status. Associations were evaluated using conditional logistic regression and adjusted for potential cofounders.
RESULTS
Among 14,119 patients diagnosed with an initial CRC during colonoscopy, 107 received a second CRC diagnosis. After exclusions for recurrent or synchronous CRC, 45 cases and 212 controls were included. There was no significant association between biopsy of non-tumor sites after initial CRC biopsy and risk of metachronous CRC in the segment of the additional biopsy site (adjusted odds ratio, 2.29; 95% confidence interval, 0.77-6.81).
CONCLUSIONS
Metachronous cancers are not significantly associated with biopsy of non-tumor sites after biopsy of the primary cancer. Although the sample size does not allow definite exclusion of any association, these findings do not support iatrogenic tumor seeding as a common risk factor for metachronous CRC.

Comparative Study
PURPOSE
Fine needle aspiration with and without concurrent core needle biopsy is a minimally invasive method to diagnose and assist in management of renal masses. We assessed the pathological accuracy of fine needle aspiration compared to and associated with core needle biopsy and the impact on management.
MATERIALS AND METHODS
We performed a single institution, retrospective study of 342 cases from 2001 to 2015 with small and large renal masses (4 or less and greater than 4 cm, respectively). Diagnostic and concordance rates, and the impact on management were analyzed.
RESULTS
Adequacy rates for fine needle aspiration only, core needle biopsy only and fine needle aspiration plus core needle biopsy were 21%, 12% and 8% (aspiration vs aspiration plus biopsy p <0.026). In the aspiration plus biopsy group adding aspiration to biopsy and biopsy to aspiration reduced the inadequacy rate from 23% to 8% and from 27% to 8% for a total reduction rate of 15% and 19%, respectively, corresponding to 32 cases (9.3%). Rapid on-site examination contributed to a 22.5% improvement in fine needle aspiration adequacy rates. In this cohort 30% of aspiration only, 5% of biopsy only and 12% of aspiration plus biopsy could not be subtyped (aspiration vs biopsy p <0.0001, aspiration vs aspiration plus biopsy p <0.0127 and biopsy vs aspiration plus biopsy p = 0.06). The diagnostic concordance rate with surgical resection was 99%. Conversion of an inadequate specimen to an adequate one by a concurrent procedure impacted treatment in at least 29 of 32 patients. Limitations include the retrospective design and accuracy measurement based on surgical intervention.
CONCLUSIONS
Fine needle aspiration plus core needle biopsy vs at least fine needle aspiration alone may improve diagnostic yield when sampling renal masses but it has subtyping potential similar to that of core needle biopsy only.

SIGNIFICANCE
Despite recent advances in multimodal optical imaging, oral imaging systems often do not provide real-time actionable guidance to the clinician who is making biopsy and treatment decisions.
AIM
We demonstrate a low-cost, portable active biopsy guidance system (ABGS) that uses multimodal optical imaging with deep learning to directly project cancer risk and biopsy guidance maps onto oral mucosa in real time.
APPROACH
Cancer risk maps are generated based on widefield autofluorescence images and projected onto the at-risk tissue using a digital light projector. Microendoscopy images are obtained from at-risk areas, and multimodal image data are used to calculate a biopsy guidance map, which is projected onto tissue.
RESULTS
Representative patient examples highlight clinically actionable visualizations provided in real time during an imaging procedure. Results show multimodal imaging with cancer risk and biopsy guidance map projection offers a versatile, quantitative, and precise tool to guide biopsy site selection and improve early detection of oral cancers.
CONCLUSIONS
The ABGS provides direct visible guidance to identify early lesions and locate appropriate sites to biopsy within those lesions. This represents an opportunity to translate multimodal imaging into real-time clinically actionable visualizations to help improve patient outcomes.

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.

Review
Fine-needle aspiration biopsy (FNAB) is a well-established initial diagnostic tool. However, in some instances limitations and shortcomings arise, making it insufficient for determining a specific diagnosis. Consequently, patients have to undergo another diagnostic procedure. The second procedure is either repeat FNAB, core-needle or open biopsy, and can be inconvenient and costly. In some centers, the FNAB is immediately followed by core-needle biopsy (CNB) in the same setting after assuring adequacy on the initial FNAB utilizing rapid on-site specimen evaluation (ROSE). It is argued that implementing such an approach will eventually have additional critical advantages that include the following: (a) it is more convenient to patients to have both procedures in one visit, (b) the tissue procured by both procedures will be more adequate, enabling cytopathologists to reach an accurate diagnosis, and (c) it is ultimately a cost-effective approach if we take into consideration the avoidance of a potential second more invasive diagnostic procedure. Since we are living in an era of patient-centered medicine coupled with cost-cutting strategies, we present here a brief review of the topic with analysis of this alternative approach, review of the pertinent literature and shed light on a few scenarios that justify this approach.
