Abstract
Acute pancreatitis is a common gastroenterological condition that can occur due to several causes. While not required for diagnosis, imaging is often performed and may reveal unexpected findings such as pancreatic masses. Malignancies such as lymphoma are uncommon causes of acute pancreatitis, especially as the initial presentation of malignancy. We present a case of a young patient with acute pancreatitis caused by diffuse large B-cell lymphoma with extranodal disease secondarily involving the pancreas. Our case highlights the importance of keeping a broad differential for acute pancreatitis and considering rare etiologies such as pancreatic lymphoma in patients without another obvious culprit.

Endoscopic Ultrasound-Guided Fine Needle Biopsy in the Diagnostic Work-Up of Deep-Seated Lymphadenopathies and Spleen Lesions: A Monocentric Experience. Diagnostics (Basel) 2023; 13:2839. [PMID: 37685377 PMCID: PMC10487140 DOI: 10.3390/diagnostics13172839] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Revised: 08/11/2023] [Accepted: 08/12/2023] [Indexed: 09/10/2023] Open
Abstract
EUS-FNB has been introduced in clinical practice as a less invasive diagnostic approach with respect to surgery. We performed a single-center retrospective study on the diagnostic efficacy of EUS-guided FNB, including 171 patients with lymph nodes, splenic, and extranodal lesions that underwent EUS for FNB at our institution. Excluding 12 patients who did not undergo FNB and 25 patients with a previous diagnosis of a solid tumor, we included 134 patients with clinical/radiological suspect of a lymphoproliferative disease, including 20 patients with a previous history of lymphoma. Out of the 134 biopsies, material of diagnostic quality was obtained in 111 procedures (84.3%). Histological examination of the EUS-FNB samples produced an actionable diagnosis in 100 cases (74.6%). Among the patients without an actionable diagnosis, a second, different diagnostic procedure produced a further eight diagnoses of lymphoma. Therefore, the sensitivity of EUS-FNB for diagnosing lymphomas was calculated to be 86.4% (51/59). Assignment of lymphomas to WHO classification subtypes was possible in 47/51 (92%) of the cases. In conclusion, EUS-FNB is an effective procedure for the histological characterization of lesions that are suspected to be lymphoproliferative disease, allowing for an actionable diagnosis in 75% of cases.

Comparison of Fine-Needle Biopsy (FNB) versus Fine-Needle Aspiration (FNA) Combined with Flow Cytometry in the Diagnosis of Deep-Seated Lymphoma. Diagnostics (Basel) 2023; 13:2777. [PMID: 37685315 PMCID: PMC10487053 DOI: 10.3390/diagnostics13172777] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Revised: 08/15/2023] [Accepted: 08/25/2023] [Indexed: 09/10/2023] Open
Abstract
Evidence comparing ultrasound endoscopy-guided fine-needle biopsy (EUS-FNB) with EUS-guided fine-needle aspiration (EUS-FNA) in deep-seated lymphoma tissue sampling is insufficient. This study aims to evaluate the diagnostic efficacy of immunohistochemistry (IHC) or flow cytometry (FCM) on specimens obtained from EUS-FNB and EUS-FNA in the diagnosis and staging of deep-seated lymphomas. This real-world, dual-center study prospectively evaluated all eligible specimens from patients who underwent EUS-FNB/FNA over an 8-year period. 53 patients were enrolled, with 23 patients in the EUS-FNB group and 30 patients in the EUS-FNA group. FNB yielded specimens with longer core tissues (0.80 mm [0.55, 1.00] vs. 0.45 mm [0.30, 0.50], p = 0.009) and higher scores of specimen adequacy [4 (3.75, 4.00) vs. 3 (1.00, 4.00), p = 0.025]. Overall analysis revealed that the diagnostic accuracy of IHC based on specimens acquired from EUS-FNB was significantly higher than that of EUS-FNA (91.30% vs. 60.00%, p = 0.013). After controlling confounding factors including lesion size and endoscopists, EUS-FNB with IHC maintained a higher-level diagnostic accuracy compared to EUS-FNA (OR = 1.292 [1.037-1.609], p = 0.023). When FCM was additionally used to analyze the specimen acquired from EUS-FNA, the diagnostic yield was significantly improved (ROC AUC: 0.733 vs. 0.550, p = 0.015), and the AUC of FNB alone or combined with FCM was 0.739 and 0.761. Conclusions: FNB needles generate higher histopathological diagnostic accuracy and specimen quality than FNA for the deep-seated lymphoma. Though the application of FCM significantly improves the diagnostic efficacy of EUS-FNA, FNB was still the preferred diagnostic modality with a shorter procedure time, comparable diagnostic accuracy, and better cost-effectiveness.

Efficacy of Contrast-Enhanced Endoscopic Ultrasonography for the Differentiation of Non-Hodgkin's Lymphoma: A Single-Center Retrospective Cohort Study. J Clin Med 2023; 12:jcm12052054. [PMID: 36902841 PMCID: PMC10004382 DOI: 10.3390/jcm12052054] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Revised: 03/02/2023] [Accepted: 03/02/2023] [Indexed: 03/08/2023] Open
Abstract
BACKGROUND Contrast-enhanced endoscopic ultrasound (CE-EUS) is a promising diagnostic modality for differentiating malignant and benign lymph nodes. This study aimed to evaluate the diagnostic capability of CE-EUS in differentiating indolent non-Hodgkin's lymphoma (NHL) from aggressive NHL. METHODS Patients who underwent CE-EUS and endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for lymphadenopathy and were diagnosed with NHL were included in this study. Echo features on B-mode endoscopic ultrasound (EUS) and vascular and enhancement patterns on CE-EUS were qualitatively evaluated. The enhancement intensity of the lymphadenopathy on CE-EUS over 60 s was also quantitatively evaluated using time-intensity curve (TIC) analysis. RESULTS A total of 62 patients who were diagnosed with NHL were enrolled in this study. Regarding qualitative evaluation using B-mode EUS, there were no significant differences in the echo features between aggressive NHL and indolent NHL. With regard to qualitative evaluation using CE-EUS, aggressive NHL showed a heterogeneous enhancement pattern that is significantly more frequent than indolent NHL (95% confidence interval: 0.57 to 0.79, p = 0.0089). When heterogeneous enhancement was defined as aggressive NHL, the sensitivity, specificity, and accuracy of the qualitative evaluation when using CE-EUS were 61%, 72%, and 66%, respectively. In TIC analysis, the velocity of reduction for homogeneous lesions was significantly higher in aggressive NHL than in indolent NHL (p < 0.0001). The sensitivity, specificity, and accuracy of CE-EUS in differentiating indolent NHL from aggressive NHL improved to 94%, 69%, and 82%, respectively, when combined with qualitative and quantitative evaluations. CONCLUSIONS CE-EUS before EUS-FNA for mediastinal or abdominal lymphadenopathy may be useful for improving the diagnostic capability of differentiating between indolent NHL and aggressive NHL (clinical trial registration number: UMIN000047907).

Abstract
Objectives:
The diagnosis of lymphoma on cytologic preparations and core needle biopsies (CNBs) is often challenging due to limited material that precludes additional ancillary testing for accurate classification. We describe our institutional experience with patients who ultimately received a diagnosis of lymphoma using cytologic preparations and CNB material along with additional ancillary testing.
Material and Methods:
All patients whose cytology material (fluids, cytologic smears, and cell block) and CNB resulted in a diagnosis of lymphoma, atypical lymphoid population, or suspicious for lymphoma were retrieved. Diagnoses of lymphoma followed the established nomenclatures of the World Health Organization (WHO). For all cases, the ancillary test profiles were captured and summarized.
Results:
Of 389 cases identified, 17 (4.4%) were diagnosed as atypical lymphoid cells and 31 (7.9%) were suspicious for lymphoma resulting in an indeterminate rate of 12.3%. The rest of the malignant cases (341; 87.7%) were classified using 2017 WHO lymphoid classification system. Six low-grade and 26 high-grade B-cell lymphomas were not further classified because of limited tissue. B-cell lymphomas were the largest category (73.0%): Primarily diffuse large B-cell lymphoma (21.4%), followed by follicular lymphoma (17.5%) and chronic lymphocytic leukemia/small lymphocytic lymphoma (10.9%). A total of 140 cases (36.0%) had flow cytometry results, but 30 specimens (21.4%) were insufficient. Cytogenetic and molecular studies were performed for 78 cases (20.0%).
Conclusion:
Full classification of lymphomas is possible with combined cytologic preparations and CNB material and it is an attractive first sampling modality in the diagnostic process for this disease group.

Abstract
Objectives:
Endoscopic ultrasound-guided fine-needle aspiration cytology (EUS-FNAC) is an effective method to acquire tissue from the mucosal, submucosal, and peri-intestinal structure with the pancreas being the most common organ to be targeted. This study is aimed to evaluate the role of EUS-FNAC in pancreatic lesions as well as other gastrointestinal (GI) structures including lymph nodes, upper GI tract, liver, and spleen.
Material and Methods:
A total of 71 cases were taken in which EUS FNAC was performed over 19 months (2018–July 2019). The details analysis of the cytological features was performed in all these cases along with the clinical outcome. The diagnostic efficacy of the EUS-FNAC was evaluated in these cases.
Results:
Out of 71 cases, 36 (50.7%) were male. The most common site being the pancreas 45 (60%) followed by intra-abdominal lymph nodes in 13(17.3%) cases and stomach 7 (9.3%). The neoplastic aspirate was noted in 38 (50.7%) cases. Among malignant lesion, adenocarcinoma was the most common; however, uncommon malignancies such as metastatic malignant melanoma and acinar cell carcinoma were also noted. Malignant lesion in pancreas includes adenocarcinoma (n = 11, 24.4%) followed by neuroendocrine tumor (n = 7, 15.6%). Tuberculosis was one of the common benign lesions to be reported.
Conclusion:
EUS-FNAC is an effective tool in the diagnosis of GI lesion particularly in the pancreas where it can avoid unnecessary surgical intervention in advanced malignancies. It can effectively obtain samples for molecular markers for pancreatic cancers. Nonetheless, diagnosing tuberculosis in inaccessible lymph nodes with its help is a lifesaving approach especially in developing countries.

Abstract
OBJECTIVES Primary pancreatic lymphoma (PPL) is rare, mimicking pancreatic ductal adenocarcinoma (PDAC) clinically and radiologically. The aim of this study is to evaluate the clinical, radiologic, and pathological characteristics of PPL diagnosed by fine-needle aspiration (FNA) in our institution. METHODS Patient clinical, radiologic, and pathological information was collected from the electronic health record system. RESULTS In total, 11 of 4,353 pancreatic FNAs met the criteria. The most common clinical symptom was jaundice, followed by abdominal pain, weight loss, and diarrhea. Abnormal laboratory findings included elevated alkaline phosphatase, total bilirubin, lactate dehydrogenase, and cancer antigen 19-9. Abnormal radiologic findings included pancreatic mass, biliary dilatation, vessel encasement, and common bile duct encasement and thickening. Five patients underwent more than 1 tissue sampling procedure before the final diagnosis of lymphoma. Final pathologic diagnosis included 7 large B-cell lymphomas and 4 follicular lymphomas. Flow cytometric analysis was performed on 9 specimens, and all demonstrated an aberrant monoclonal B-cell population. CONCLUSIONS PPL mimics PDAC clinically and radiologically and could be a challenge for pathologic diagnosis if lymphoma is not included in the differential diagnosis during immediate evaluation. If lymphoma is suspected during immediate evaluation, PPL could be reliably diagnosed by FNA with the aid of ancillary studies.

Abstract
EUS has become a substantial diagnostic and therapeutic modality for many anatomical regions. The extent of endosonographic assessment is wide, and among others, allows for the evaluation of the mediastinal anatomy and related pathologies such as mediastinal lymphadenopathy and staging of central malignant lung lesions. Moreover, EUS assessment has proved more accurate in detecting small lesions missed by standard imaging examinations such as computed tomography or magnetic resonance. Endosonographically, various mediastinal anatomical landmarks and stations can be visualized by transesophageal scanning, thus providing arranged systematic examination of the mediastinum. In addition, the correct position during the examination is crucial for EUS-guided procedures such as tissue sampling and drainage of mediastinal abscesses. The evolution of EUS-guided diagnostic and interventional procedures has contributed to the increasing importance of understanding the mediastinal anatomy during the EUS examination.

Abstract
BACKGROUND endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is a safe and effective technique in the diagnosis of mediastinal and abdominal masses. However, the usefulness of EUS-FNA in the diagnosis and classification of lymphomas is controversial. The aim of this study was to determine the yield of EUS-FNA in the diagnosis and classification of lymphomas. METHODS a retrospective case series was performed in a tertiary referral center. All consecutive patients referred for EUS-FNA with a suspected diagnosis of lymphoma from March 2013 to June 2019 were included. RESULTS thirty-five patients (54.3 % women, median age 72 years) were included. The most frequent location of the node was the abdomen (67.9 %). Nodes were punctured using a 22-gauge (85.7 %) and 19-gauge needle (14.3 %) with a slow-pull technique. The number of passes performed were three or more in 82.9 % of patients. The samples were processed by the cellblock method. Adequate samples for immunohistochemical and molecular biological study were obtained in 33 (94.3 %) patients. EUS-FNA correctly diagnosed lymphoma in 30 out of 35 patients (85.7 %), and subclassification was determined in 23 patients (65.7 %). The most frequent diagnosis was non-Hodgkin lymphoma (85.7 %). There was one moderate adverse event (bleeding), which was resolved during the procedure. CONCLUSIONS EUS-FNA may be a valuable technique in the evaluation of suspected lymphomas with an adequate diagnostic yield and a very low rate of adverse events.

Diagnosis of Hodgkin Lymphoma from Cell Block: A Reliable and Helpful Tool in "Selected" Diagnostic Practice. Diagnostics (Basel) 2020; 10:diagnostics10100748. [PMID: 32992679 PMCID: PMC7601842 DOI: 10.3390/diagnostics10100748] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2020] [Revised: 09/18/2020] [Accepted: 09/23/2020] [Indexed: 01/10/2023] Open
Abstract
Background: The diagnosis of lymphoma requires surgical specimens to perform morphological evaluation, immunohistochemical and molecular analyses. Ultrasound-guided fine needle aspiration may represent an appropriate first approach to obtain cytological samples in impalpable lesions and/or in patients unsuitable for surgical procedures. Although cytology has intrinsic limitations, the cell block method may increase the possibility of achieving an accurate diagnosis. Methods: We retrospectively selected a total of 47 ultrasound-guided fine needle aspiration and drainage samples taken from patients with effusion and deep-seated lesions which are clinically suspicious in terms of malignancy. Results: In 27 cases, both cell block and conventional cytology were performed: 21/27 cell blocks were adequate for the diagnosis of lymphoma and suitable for immunocytochemistry and molecular analyses vs. 12/20 samples to which only conventional cytology was applied. Moreover, in five patients we were able to make a diagnosis of Hodgkin lymphoma with the cell block (CB) technique. Conclusions: Contrary to conventional cytology, the cell block method may allow immunocytochemistry and molecular studies providing useful information for the diagnosis and subtypization of lymphoma in patients unsuitable for surgical procedure or with deep-seated lesions or extra-nodal diseases; additionally, it is a daily, simple and helpful approach. Moreover, we describe the usefulness of cell blocks in the diagnosis of Hodgkin lymphoma.

Abstract
Background: Endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNAB) has become an important modality for identification of intra-abdominal masses. This study analyzed the accuracy of EUS-FNAB in a single medical center and explored factors related to positive diagnosis. Materials and methods: In total, 77 patients with EUS-FNAB were retrospectively reviewed from July 2016 to February 2020. "Atypical (tends to be neoplasm/malignancy)," "suspicious (first consider neoplasm/malignancy)," and "malignant" were defined as positive cytology. The final diagnoses were based on histopathologic examination. The positive rate of EUS-FNAB for the diagnosis of neoplasm and its associations with age, sex, target puncture mass size, liver function, tumor markers, albumin, hypertension, and diabetes were examined. Results: Accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of EUS-FNAB cytologic diagnoses in all patients were 77.9% (60/77), 76.1% (54/71), 100%, 100%, and 26.1% (6/23), respectively. Accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of EUS-FNAB cytologic diagnoses in the pancreas were 80.0% (48/60), 79.3% (46/58), 100%, 100%, and 14.3% (2/14), respectively. The results of EUS-FNAB in pancreatic masses showed that the level of CA19-9 was higher in the true positive group than in the false-negative group (p<0.05). There were no factors associated with the true positive cytologic diagnoses (p>0.05). Conclusions: Our single-medical center study showed that EUS-FNAB is an accurate diagnostic procedure for the evaluation of intra-abdominal masses. Further follow-up is required to explore factors associated with the true positive cytology.

Endoscopic Ultrasound Fine-Needle Aspiration versus Fine-Needle Biopsy for Lymph Node Diagnosis: A Large Multicenter Comparative Analysis. Clin Endosc 2019; 53:600-610. [PMID: 31794654 PMCID: PMC7548151 DOI: 10.5946/ce.2019.170] [Citation(s) in RCA: 22] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2019] [Accepted: 09/26/2019] [Indexed: 02/06/2023] Open
Abstract
Background/Aims Endoscopic ultrasound fine-needle aspiration (EUS-FNA) is preferred for sampling of lymph nodes (LNs) adjacent to the gastrointestinal wall; however, fine-needle biopsy (FNB) may provide improved diagnostic outcomes. This study aimed to evaluate the comparative efficacy and safety of FNA versus FNB for LN sampling.
Methods This was a multicenter retrospective study of prospectively collected data to evaluate outcomes of EUS-FNA and EUS-FNB for LN sampling. Characteristics analyzed included sensitivity, specificity, accuracy, the number of needle passes, diagnostic adequacy of rapid on-site evaluation (ROSE), cell-block analysis, and adverse events.
Results A total of 209 patients underwent EUS-guided LN sampling. The mean lesion size was 16.22±8.03 mm, with similar sensitivity and accuracy between FNA and FNB ([67.21% vs. 75.00%, respectively, p=0.216] and [78.80% vs. 83.17%, respectively, p=0.423]). The specificity of FNB was better than that of FNA (100.00% vs. 93.62%, p=0.01). The number of passes required for diagnosis was not different. Abdominal and peri-hepatic LN location demonstrated FNB to have a higher sensitivity (81.08% vs. 64.71%, p=0.031 and 80.95% vs. 58.33%, p=0.023) and accuracy (88.14% vs. 75.29%, p=0.053 and 88.89% vs. 70.49%, p=0.038), respectively. ROSE was a significant predictor for accuracy (odds ratio, 5.16; 95% confidence interval, 1.15–23.08; p=0.032). No adverse events were reported in either cohort.
Conclusions Both EUS-FNA and EUS-FNB are safe for the diagnosis of LNs. EUS-FNB is preferred for abdominal LN sampling. EUS-FNA+ ROSE was similar to EUS-FNB alone, showing better diagnosis for EUS-FNB than traditional FNA. While ROSE remained a significant predictor for accuracy, due to its poor availability in most centers, its use may be limited to cases with previous inconclusive diagnoses.

Abstract
Although quite rare, retroperitoneum can harbour malignant limphomas. On the grounds that the anatomical location is uncommon and the symptoms are scarce, the diagnosis is usually late and challenging. Imaging methods such as magnetic resonance imaging, computed tomography (CT) and positron emission tomography-computed tomography (PET-CT), can characterize and locate the tumor while endoscopic ultrasound fine needle aspiration (EUS-FNA) may provide pathological confirmation. We present the clinical case of a fifty-five-year-old female that is admitted to our hospital with epigastric discomfort, nausea and vomiting. CT showed a homogenously enhancing mass lesion that encased the pancreas, in contact with the portal vein, inferior vena cava, invading splenomesenteric confluence. To investigate further, EUS-FNA was decided and it revealed lymphocyte proliferation suggestive for the diagnosis of lymphoma. Hereinafter, surgical intervention was performed and immunohistochemical analysis and sub classification of lymphoma was obtained. The final diagnosis was non-Hodgkin lymphoma, Diffuse Large B-Cell Lymphoma (DLBCL). Poly-chemotherapy with R-CHOP was initiated. At the end of the treatment fluorodeoxyglucose positron emission tomography (FDG-PET) was performed and no pathological findings were found. A brief review of literature is also provided.

Abstract
INTRODUCTION Controversy remains as to whether image-guided fine-needle aspiration (FNA) biopsy coupled with appropriate ancillary techniques has clinical utility in the diagnosis of deep-seated lymphomas. MATERIALS AND METHODS A retrospective search (20 years) was performed to identify FNA cases with a definitive or indeterminate lymphoma diagnosis for deep-seated locations. The FNA diagnosis was compared with corresponding surgical pathology (SP) and clinical follow-up. The application of ancillary tests was also evaluated. RESULTS A total of 121 cases from 118 patients were recovered. Among 95 of 121 (79%) aspirates that had a definitive lymphoma diagnosis, 50 lacked SP follow-up. Most (82%) represented possible recurrent lymphoma, and thus therapy proceeded based on the FNA results alone. Additionally, 44 of 95 (46%) had an FNA diagnosis concordant with corresponding SP and 1 case was discordant. Of 44 with concordant SP diagnosis, 25 had further lymphoma subtyping that was concordant with SP. There were 26 of 121 (21%) with indeterminate diagnosis on FNAs. Of these, SP confirmed a diagnosis of lymphoma in 81%. Indeterminate cytologic diagnoses were due either to absent/inconclusive flow cytometry (FC) (11 of 21) or Hodgkin lymphoma (10 of 21). Of 121 cases, 93 utilized FC, 53 utilized cell-block immunohistochemical stains, and 29 utilized molecular testing as part of FNA work-up. CONCLUSIONS FNA plays an important role in the diagnosis/clinical management of deep-seated non-Hodgkin B cell lymphoma (NHL), particularly for recurrence. The addition of ancillary techniques, particularly FC, markedly increases NHL diagnostic accuracy and subclassification. Our study is one of the few large series examining the clinical utility of FNA in the setting of deep-seated lymphomas.

Abstract
Endoscopic ultrasound (EUS) is considered a valuable diagnostic tool during the workup of malignant gastric lesions, including primary gastric lymphomas (PGL). Although endoscopy combined with multiple biopsies remains essential in the establishment of PGL diagnosis, EUS utilization in locoregional disease staging has been well documented in the literature. Data also support the possible role of EUS in prediction of response to first-line treatment, that is, Helicobacter pylori eradication. However, its application in the posttreatment setting remains problematic, since concordance rates between endosonography and histology findings during follow-up seem to vary substantially. The aim of the present review is to summarize all available data regarding the role of EUS in the management of PGL.

Abstract
Pancreatic cytopathology, particularly through the use of endoscopic ultrasound-guided fine-needle aspiration (FNA), has excellent specificity and sensitivity for the diagnosis of pancreatic lesions. Such diagnoses can help guide preoperative management of patients, provide prognostic information, and confirm diagnoses in patients who are not surgical candidates. Furthermore, FNA can be used to obtain cyst fluid for ancillary tests that can improve the diagnosis of cystic lesions. In this article, we describe the cytomorphological features and differential diagnoses of the most commonly encountered pancreatic lesions on FNA.

Abstract
Evaluation of deep-seated lymphomas by fine-needle aspiration (FNA) can be challenging due to their reduced accessibility. Controversy remains as to whether FNA and ancillary techniques can be used to diagnose deep-seated lymphomas reliably and sufficiently for clinical management. Most published studies are favorable that endobronchial ultrasound (EBUS)/endoscopic ultrasound (EUS)-FNA plays an important role in the diagnosis of deep-seated lymphomas. The addition of ancillary techniques, particularly flow cytometry, increases diagnostic yield. While subclassification is possible in a reasonable proportion of cases, the reported rates of successful subclassification are lower than those for lymphoma detection/diagnosis. The diagnostic limitation exists for Hodgkin's lymphoma, grading of follicular lymphoma, and some T-cell lymphomas. The role of FNA in deep-seated lymphomas is much better established for recurrent than primary disease. It remains unclear whether the use of large-sized-needle FNA or a combination of core needle biopsy and FNA improves subclassification. It is important for cytopathologists to have considerable understanding of the WHO lymphoma classification and develop a collaborative working relationship with hematopathologists and oncologists. As EUS/EBUS-FNA techniques advance and sophisticated molecular techniques such as next- generation sequencing become possible, the role of FNA in the diagnosis of deep-seated lymphomas will possibly increase.

Abstract
OBJECTIVE Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) has recently been used for the evaluation of various lesions arising in the porta hepatis. The purpose of this study is to evaluate the diagnostic yield of this increasingly utilized approach to porta hepatis lesions. STUDY DESIGN A retrospective study of 72 consecutive samples of porta hepatis lesions obtained via EUS-FNA between 2004 and 2015 was conducted. Clinical histories and endoscopic findings were available prior to the diagnostic interpretation. The diagnosis of each lesion was based on its cytologic features on smears, its histologic features on cell block, a comparison with any relevant prior specimens, immunohistochemistry and flow cytometric studies when applicable. RESULTS A total of 72 lesions (59 lymph nodes, 2 cysts and 11 masses) were biopsied in 70 patients. Adequate specimens were obtained in 65/72 cases (90%). Most of the lymph nodes were benign (n = 40, 67%) and most of the masses were malignant or suspicious (n = 8, 73%). A variety of diagnoses, primary and metastatic, were made, including hepatocellular carcinoma, cholangiocarcinoma and lymphoma. In addition, we have noted a significant increase in the number of EUS-FNAs in recent years. CONCLUSION EUS-FNA is an effective and increasingly utilized diagnostic approach for the evaluation of multiple types of lesions in the porta hepatis.

Abstract
BACKGROUND The usefulness of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for evaluating hilar, mediastinal and central parenchymal lesions has been well established. However, its utility for diagnosing lymphoma is controversial. The aim of this study was to evaluate the diagnostic utility of EBUS-TBNA for the definitive diagnosis of de novo lymphoma with subtype classification. METHODS Patients with lymphoma who underwent EBUS-TBNA for diagnostic purposes at a single institution between March 2004 and May 2013 were retrospectively reviewed. RESULTS Of the 971 patients who underwent EBUS-TBNA during the study period, 19 patients, who did not have a previous history of lymphoma, had a final diagnosis of lymphoma. EBUS-TBNA provided a diagnosis accompanied with subtype classification in 6 patients (32%), a suspicious but not definitive classification in 10 patients (53%), and a negative classification in 3 patients (16%). Immunohistochemical staining for definitive diagnosis was performed in 15 of 16 patients (94%), with suspicious results from routine hematoxylin and eosin staining. No procedure-related complications occurred. CONCLUSIONS EBUS-TBNA is a useful initial diagnostic procedure, aiding decisions for the management of patients with suspected lymphoma, even though the sensitivity of EBUS-TBNA for diagnosing lymphoma with subtype classification was lower than previously reported.

BACKGROUND EUS-guided fine needle aspiration biopsy (EUS-FNAB) of deep-seated lymphadenopathy is proposed to identify lymphoproliferative disorders when no superficial lesion is accessible. METHODS We analyzed prospectively collected data of 115 EUS-FNABs from 73 thoracic or abdomino-pelvic targets in 52 patients with suspected lymphoproliferative disorders (LPDs) between January 2005 and May 2011 from a single institution. Conventional histology and immunohistochemistry procedures were performed on samples. RESULTS No complications were recorded. An LPD was identified in 29 cases and ruled out in 21 cases. In 2 cases the analysis was negative, but an LPD was identified using a secondary procedure. For the identification of LPDs irrespective of subtype, this procedure has positive and negative predictive values of 100% and 91.3% respectively, with 93.6% sensitivity and 100% specificity. In 31 patients finally diagnosed with LPDs, an accurate diagnosis meeting the 2008 World Health Organization classification criteria was established in 21 (68%) cases, success being significantly associated with target size above 30 mm in multivariate analysis (odds ratio 7.47; p = 0.05). CONCLUSION EUS-FNAB of deep-seated lymphadenopathy with conventional morphological assessment appears to have a high diagnostic value for LPD identification and can obviate invasive surgery. A sub-classification was possible in two thirds of the cases.

Abstract
Since its introduction in the early 1990s, endoscopic ultrasound-assisted fine-needle aspiration (EUS-FNA) has been used for sampling of extraintestinal mass lesions and peri-intestinal lymphadenopathy. Although EUS-FNA is highly accurate, lymphomas can be challenging to diagnose using EUS-FNA. We present the case of a 60-year-old male who had experienced upper abdominal discomfort for 1 month. Computerized tomography (CT) examination revealed multiple soft-tissue shadows located above the pancreatic body. The biggest shadow had a cross-sectional area of 7.7 cm × 7.2 cm. Positron emission tomography-CT (PET-CT) imaging showed increased uptake of 18F-FDG by these soft-tissue shadows. To investigate further, EUS was performed and it revealed the presence of multiple hypoechoic round lymph nodes. During the procedure, EUS-FNA was performed, but only a few dyskaryotic cells were observed by cytological evaluation. EUS-assisted retroperitoneoscopy and lymph node biopsy were performed to obtain more tissue for immunohistochemical analysis and subclassification of lymphoma. Finally, the patient was diagnosed with non-Hodgkin lymphoma, germinal center B-cell-like diffuse large B-cell lymphoma by this technique. EUS-assisted transendoscopic retroperitoneal lymph node biopsy is an alternative procedure for the diagnosis of lymphomas.

Abstract
Endoscopic ultrasound (EUS)-guided fine needle aspiration has emerged as the procedure of choice to obtain samples to reach a definitive diagnosis of lesions of the gastrointestinal tract and of adjacent organs. The obtainment of a tissue core biopsy presents several advantages that can substantially contribute to the widespread diffusion of EUS utilization in the community and in countries where cytology expertise may be difficult to be achieved. This article will review the EUS-guided fine needle biopsy techniques developed so far, the clinical results, their limitations as well as their future perspective.

Abstract
Accurate diagnosis and subtyping of lymphoma have important prognostic implications and are generally required for treatment planning. Histological assessment, immunophenotyping, and genetic studies are usually necessary. Endoscopic ultrasound guided-fine needle aspiration cytology (EUS-FNAC) is a minimally invasive technique widely used for the evaluation of deep-seated benign and malignant lesions. However, the value of cytological samples in lymphoma diagnosis is still a matter of debate. Endoscopic ultrasound guided-fine needle biopsy (EUS-FNAB) can provide tissue core samples that may help overcome the limitations of cytology. The aim of this review is to summarize the available literature regarding EUS-FNAC and EUS-FNAB for the diagnosis and subtyping of lymphoma. In addition, we discuss its usefulness in the management of primary extra-nodal lymphomas, as well as technical issues that may influence sample quality.

Abstract
Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is a technique which allows the study of cells obtained through aspiration in different locations near the gastrointestinal tract. EUS-FNA is used to acquire tissue from mucosal/submucosal tumors, as well as peri-intestinal structures including lymph nodes, pancreas, adrenal gland, gallbladder, bile duct, liver, kidney, lung, etc. The pancreas and lymph nodes are still the most common organs targeted in EUS-FNA. The overall accuracy of EUS is superior to computed tomography scan and magnetic resonance imaging for detecting pancreatic lesions. In most cases it is possible to avoid unnecessary surgical interventions in advanced pancreatic cancer, and EUS is considered the preferred method for loco-regional staging of pancreatic cancer. FNA improved the sensitivity and specificity compared to EUS imaging alone in detection of malignant lymph nodes. The negative predictive value of EUS-FNA is relatively low. The presence of a cytopathologist during EUS-FNA improves the diagnostic yield, decreasing unsatisfactory samples or need for additional passes, and consequently the procedural time. The size of the needle is another factor that could modify the diagnostic accuracy of EUS-FNA. Even though the EUS-FNA technique started in early nineteen's, there are many remarkable progresses culminating nowadays with the discovery and performance of needle-based confocal laser endomicroscopy. Last, but not least, identification and quantification of potential molecular markers for pancreatic cancer on cellular samples obtained by EUS-FNA could be a promising approach for the diagnosis of solid pancreatic masses.

Abstract
BACKGROUND Primary pancreatic lymphoma is a rare tumour of the pancreas. Data on the role of endoscopic ultrasound guided fine needle aspiration for its diagnosis are scant. AIM To identify the frequency of occurrence, sonographic characteristics and cytological findings that are predictive of primary pancreatic lymphoma. METHODS Pancreatic lymphoma cases were identified by retrospective review of solid pancreatic masses over 10-year period. RESULTS 12/2397 (0.5%) lesions were identified. Patients were predominantly white (92%) and male (58%). Mean largest dimension was 47.5mm and 83.3% were located in the head. The mass appeared heterogeneous in 75% and peripancreatic lymphadenopathy was noted in 58%. None of the patients showed features of chronic pancreatitis or pancreatic ductal dilation. Rapid onsite analysis revealed atypical lymphocytes in 92%. Flow cytometry confirmed diagnosis in 75% of cases. CONCLUSIONS Primary pancreatic lymphoma is encountered in 0.5% of patients undergoing endoscopic ultrasound guided fine needle aspiration. A large heterogeneous mass, in the absence of chronic pancreatitis or pancreatic duct dilation that reveals atypical lymphocytes on fine needle aspiration is suggestive.

Abstract
Immunophenotyping of paucicellular samples may represent a diagnostic challenge in the flow cytometry (FC) laboratory routine, as the scarcity of cells limits the number of tests that can be performed. Specimens such as fine needle aspirates (FNA), human body fluids (BF), cerebrospinal fluid (CSF), or ocular fluid (OF) sent for FC investigations in the case of suspicion of lymphoma, or for lymphoma monitoring, may contain very low numbers of cells. In these cases, it is mandatory to obtain the largest amount possible of useful information from a single tube. The basic protocol described in this unit provides a method that combines the use of multiple monoclonal antibodies (MAbs) with a Boolean gating strategy to identify and quantify the main lymphocyte populations, as well as to detect lymphomatous B cells or any aberrant T cell expression, if present, in paucicellular samples.

Abstract
RATIONALE The current management of lymphoma requires accurate diagnosis and subtyping of de novo lymphoma and of relapsed or refractory lymphoma in known cases. The role of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in the clinical management of lymphomas is unclear. OBJECTIVES To investigate the use of EBUS-TBNA in the diagnosis of de novo and relapsed mediastinal lymphomas. METHODS A total of 2,256 consecutive patients who underwent EBUS-TBNA in a tertiary center between February 2008 and April 2013 were prospectively evaluated. The diagnostic accuracy and clinical use of EBUS-TBNA in 100 cases of de novo or suspected relapsed mediastinal lymphoma was investigated by comparing EBUS-TBNA diagnosis with the final diagnosis. MEASUREMENTS AND MAIN RESULTS De novo mediastinal lymphoma was correctly diagnosed by EBUS-TBNA in 45 (88%) of 51 and relapsed lymphoma in 15 (100%) of 15 lymphoma cases. EBUS-TBNA accurately established a diagnosis other than lymphoma in 32 (97%) of 33 patients with suspected lymphoma relapse. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of EBUS-TBNA in the diagnosis of mediastinal lymphoma were 89%, 97%, 98%, 83%, and 91%, respectively. Sensitivity of EBUS-TBNA in subtyping lymphomas into high-grade non-Hodgkin lymphoma, low-grade non-Hodgkin lymphoma, and Hodgkin lymphoma was 90%, 100%, and 79%, respectively. EBUS-TBNA diagnosis was adequate for clinical management in 84 (84%) of 100 cases. CONCLUSIONS Multimodality evaluation of EBUS-TBNA can be successful in the diagnosis of de novo mediastinal lymphomas and is ideally suited in distinguishing lymphoma relapse from alternative pathologies; it is least sensitive in subtyping Hodgkin lymphoma.

Abstract
Although endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is the method of choice to obtain samples to reach definitive diagnosis of lesions of the gastrointestinal tract and of adjacent organs, it cannot fully characterize certain neoplasms. The lack of cytology expertise has hindered the dissemination of EUS, limiting its widespread use. The obtainment of a tissue specimen through EUS fine-needle biopsy (EUS-FNB) may overcome the limitations of EUS-FNA. EUS-FNB is expected to move the practice of EUS from cytology to histology, expanding the use of EUS and facilitating targeted therapies and monitoring of treatment response in a more biologically driven manner.

Abstract
OBJECTIVES Thoracic and abdominal lymph nodes may be enlarged in a variety of disorders. Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is a well-established technique for sampling such nodes, but samples obtained are small, which may make definitive diagnosis difficult. We conducted a retrospective review to determine the contribution of ancillary techniques, such as special histochemistry (SHC), immunohistochemistry (IHC) and flow cytometry, in increasing the diagnostic yield of EUS-FNA carried out at our institution. STUDY DESIGN Between November 2005 and December 2012, 278 patients underwent EUS-FNA of enlarged thoracic and abdominal nodes at our institution. All specimens obtained were subjected to rapid on-site evaluation. Data were reviewed in all patients requiring ancillary techniques for definitive diagnosis. RESULTS Ancillary techniques were performed in 111 of 278 cases. IHC was performed in 24, flow cytometry in 3 and SHC staining in 84. IHC and SHC aided in reaching a definitive diagnosis in 19 of 24 and 3 cases, respectively. Flow cytometry led to a definitive diagnosis in 3 cases. A total of 80 cases were also submitted to culture for tuberculosis with 6 positive for Mycobacterium tuberculosis. CONCLUSIONS Ancillary studies in EUS-FNA of thoracic and abdominal lymph nodes can significantly improve the yield of EUS-FNA.

Abstract
Endoscopic ultrasonography (EUS) has recently gained a pivotal role in the management of gastric lymphomas, especially in the diagnostic workup. Its accuracy and reliability have overcome those of other imaging techniques, such that it represents an invaluable tool for the management of gastric lymphomas. Although this technique is operator dependent, its application in large series has proved its reliability. Thus, it has generally been considered a useful tool for providing information crucial in deciding the treatment program, especially for mucosa-associated lymphoid tissue (MALT) lymphomas, for which EUS can provide an accurate evaluation of disease extension and treatment response probability. Limited-stage disease, confined to the submucosa, has a greater probability to respond to sole Helicobacter pylori eradication. In contrast, the value of EUS in response assessment and follow-up monitoring is still debated, with discordant opinions about its reliability and clinical advantages, because normalization of the EUS findings occurs with a considerable delay compared to the histologic evaluation. In the follow-up setting, preliminary data have indicated that persistently positive EUS findings in low-grade gastric lymphoma could represent a warning for a possible relapse. However, in high-grade gastric lymphoma, such findings do not have any clinical implications.

Abstract
OBJECTIVES The field of cytopathology has been rapidly advancing in the era of molecular pathology and personalized medicine. On-site cytologic evaluation for adequacy and triaging specimens for small core biopsy or fine-needle aspiration (FNA) are often required. Cytopathologists face the challenge of how to best triage small specimens for diagnosis, molecular testing, and personalized treatment. Owing to its minimally invasive nature, FNA alone or combined with core biopsy for lymphoproliferative disorders and soft tissue tumors has gained popularity. METHODS Literature review and author's institutional experience are used for this review article. This article will focus mainly on lymphoproliferative disorders and soft tissue tumors. RESULTS Evaluation combining cytomorphology, immunohistochemistry, and/or molecular pathology is often needed to accurately diagnose and classify lymphomas and soft tissue tumors. Many molecular tests have been performed on cytologic specimens, such as tests for BRAF and RET in thyroid FNA. CONCLUSIONS Molecular pathology has been widely integrated into conventional cytopathology for diagnosing lymphoproliferative disorders and soft tissue tumors, and the diagnostic value of FNA on those tumors has increased significantly. Cytology will play a more important role in the era of personalized medicine.

Abstract
Primary gastrointestinal lymphoma comprises 10-15% of all non-Hodgkin lymphomas and encompasses 30-40% of the total extranodal lymphomas. Approximately 60-75% of cases occur in the stomach, and then the small bowel, ileum, cecum, colon and rectum. Lymphoid neoplasms may consist of mature B, T and less commonly extranodal NK/T cells. Of these, the two most frequently encountered histologic subtypes are extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma), where Helicobacter pylori infection is implicated in a number of cases, and diffuse large B cell lymphoma. Several B cell lymphomas are associated with chromosomal aberrations. Enteropathy-associated T cell lymphoma, type I in particular, usually arises in a background of celiac disease. T cell gene rearrangement confirms clonality. NK/T cell neoplasms are invariably associated with Epstein-Barr virus infection and are often aggressive; thus, differentiation from a benign NK-cell enteropathy is paramount. Although incidence of other hematopoietic malignancies in the gastrointestinal tract such as plasma cell myeloma associated with amyloidosis, plasmablastic lymphoma, Hodgkin disease, histiocytic sarcoma and mast cell sarcoma is extremely rare, these entities have been documented, with the latter two demonstrating aggressive clinical behavior. Endoscopic ultrasonography is an important adjunct in disease staging and follow-up. Conservative antibiotic treatment of stage I MALT lymphomas with associated Helicobacter pylori infection achieves good clinical outcome with high remission rate. Chemotherapy, radiation and rarely surgery are reserved for advanced diseases or cases resistant to conservative therapy and those not associated with Helicobacter pylori infection.

World J Gastroenterol 2012; 18:2357-63. [PMID: 22654426 PMCID: PMC3353369 DOI: 10.3748/wjg.v18.i19.2357] [Citation(s) in RCA: 36] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/15/2011] [Revised: 09/24/2011] [Accepted: 04/12/2012] [Indexed: 02/06/2023] Open
Abstract
AIM: To assess the characteristics and quality of endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA) in a large panel of endosonographers.
METHODS: A survey was conducted during the 13th annual live course of endoscopic ultrasonography (EUS) held in Amsterdam, Netherlands. A 2-page questionnaire was developed for the study. Content validity of the questionnaire was determined based on input by experts in the field and a review of the relevant literature. It contained 30 questions that pertained to demographics and the current practice for EUS-FNA of responders, including sampling technique, sample processing, cytopathological diagnosis and sensitivity of EUS-FNA for the diagnosis of solid mass lesions. One hundred and sixty-one endosonographers who attended the course were asked to answer the survey. This allowed assessing the current practice of EUS-FNA as well as the self-reported sensitivity of EUS-FNA for the diagnosis of solid mass lesions. We also examined which factors were associated with a self-reported sensitivity of EUS-FNA for the diagnosis of solid mass lesions > 80%.
RESULTS: Completed surveys were collected from 92 (57.1%) of 161 endosonographers who attended the conference. The endosonographers had been practicing endoscopy and EUS for 12.5 ± 7.8 years and 4.8 ± 4.1 years, respectively; one third of them worked in a hospital with an annual caseload > 100 EUS-FNA. Endoscopy practices were located in 29 countries, including 13 countries in Western Europe that totaled 75.3% of the responses. Only one third of endosonographers reported a sensitivity for the diagnosis of solid mass lesions > 80% (interquartile range of sensitivities, 25.0%-75.0%). Factors independently associated with a sensitivity > 80% were (1) > 7 needle passes for pancreatic lesions or rapid on-site cytopathological evaluation (ROSE) (P < 0.0001), (2) a high annual hospital caseload (P = 0.024) and (3) routine isolation of microcores from EUS-FNA samples (P = 0.042). ROSE was routinely available to 27.9% of respondents. For lymph nodes and pancreatic masses, a maximum of three needle passes was performed by approximately two thirds of those who did not have ROSE. Microcores were routinely harvested from EUS-FNA samples by approximately one third (37.2%) of survey respondents.
CONCLUSION: EUS-FNA sensitivity was considerably lower than reported in the literature. Low EUS-FNA sensitivity was associated with unavailability of ROSE, few needle passes, absence of microcore isolation and low hospital caseload.

Endoscopic ultrasound-guided fine needle aspiration biopsy for diagnosis of lymphoproliferative disorders: feasibility of immunohistological, flow cytometric, and cytogenetic assessments. Am J Gastroenterol 2012; 107:397-404.

Abstract
OBJECTIVES In addition to morphology, immunophenotype and genetic abnormalities should be assessed during diagnosis and subclassification of lymphoproliferative disorders. The objective of this study was to evaluate the yield of endoscopic ultrasound-guided fine needle aspiration biopsy (EUS-FNAB) using a standard 19-gauge needle for diagnosis and subclassification of lymphoma, assessing the feasibility of immunohistological, flow cytometric, and cytogenetic assessments. METHODS Two hundred forty patients with suspected lymphoma were referred for EUS-FNAB to our quaternary EUS center between June 2005 and December 2010. EUS-FNAB using a conventional 19-gauge needle was attempted for all patients, followed by histological assessments including immunohistological staining, flow cytometry, and cytogenetic analysis (G-band karyotyping). Among the patients, 152 were ultimately diagnosed with lymphoma. The primary outcome measure of this study was the sensitivity of histological assessment, including immunohistological staining, flow cytometry, and G-band karyotyping, for diagnosis and subclassification of lymphoma. RESULTS Among the 152 patients ultimately diagnosed with lymphoma, 147 patients (96.7%) were diagnosed by EUS-FNAB, and classification in accordance with the WHO (World Health Organization) system was also possible for 135 patients (88.8%) on the basis of histological findings, including immunohistological staining. Flow cytometry showed abnormal or unusual cell populations in 121 (79.6%) of the 152 patients diagnosed with lymphoma, and in 114 (90.5%) of the 126 patients diagnosed with B-cell lymphoma. Specific cytogenetic abnormalities were detected in 21 (13.8%) of the lymphoma patients. CONCLUSIONS EUS-FNAB using a standard 19-gauge needle has high diagnostic value for lymphoma. Immunophenotyping is usually possible, while cytogenetic abnormalities can be identified in a relatively limited number of patients.

Abstract
BACKGROUND The ability to obtain tissue samples for histological examination during EUS has theoretical advantages over cytology alone. OBJECTIVE To prospectively evaluate the feasibility and yield of EUS-guided fine-needle tissue acquisition (EUS-FNTA) with a large-gauge needle in patients in whom we expected histology to be more useful than cytology to reach a definitive diagnosis. DESIGN Prospective cohort study. SETTING Tertiary care academic medical center. PATIENTS Consecutive patients with subepithelial lesions, esophagogastric wall thickening, mediastinal and abdominal masses/lymphadenopathy of unknown origin, or pancreatic lesions after nondiagnostic FNA. INTERVENTIONS EUS-FNTA with a 19-gauge needle. MAIN OUTCOME MEASUREMENTS Feasibility and yield of EUS-FNTA. RESULTS A total of 120 patients with a mean age of 61 ± 14.6 years and mean lesion size of 38 ± 25 mm (range 8-140 mm) were enrolled. FNTA was successfully performed in all but 1 patient (98.9%), and adequate samples for histological examination were obtained in 116 of the 119 patients (97.5%) in whom EUS-FNTA was technically successful. A mean of 2.8 ± 0.8 passes per patient were performed. At the time of current follow-up, a definitive diagnosis was available in 117 of the 120 patients (97.5%), with only 8 false-negative results. The sensitivity, specificity, positive and negative predictive values, and diagnostic accuracy of EUS-FNTA in the 117 patients with a definitive diagnosis were 91.8%, 100%, 100%, 71.4%, and 93.2%, respectively. LIMITATIONS Single-center study with limited power. CONCLUSIONS EUS-FNTA by using a large-gauge needle has a high yield and promising diagnostic accuracy and could be used when histology may be more useful than cytology to reach a definitive diagnosis.

Endoscopic ultrasound fine needle aspiration in the diagnosis of lymphoma. JOURNAL OF ONCOLOGY 2011; 2011:785425.

Abstract
In recent years, endoscopic ultrasound techniques with Fine Needle Aspiration (FNA) have become an increasingly used diagnostic aid in the differentiation of mediastinal lymphadenopathy. Endobronchial ultrasound (EBUS) and endoesophageal ultrasound (EUS) are now available for clinicians to reach mediastinal and paramediastinal masses using a minimally invasive approach. These techniques are an established component for diagnosing and staging lung cancer and their benefit in the diagnosis of lymphoma's has been highlighted in a number of case studies. However, the lack of tissue architecture obtained by cytological FNA specimens decreases the diagnostic accuracy for benign causes of thoracic lymphadenopathies, lymphomas, and histopathological subtyping of lung cancer. Accordingly, our study group have adapted the FNA sampling technique, resulting in tissue fragments that can be used for histopathological examinations. As an illustration, we report a case of follicular non-Hodgkin lymphoma, diagnosed on tissue fragments obtained by adjusted EUS FNA. We believe that this relatively simple adjustment to routine FNA sampling can help to overcome the diagnostic limitations inherent in cytology obtained by routine FNA.

Abstract
OBJECTIVE Although endoscopic ultrasound combined with fine needle aspiration (EUS-FNA) is rapidly becoming the preferred diagnostic approach for the sampling and diagnosis of gastrointestinal and mediastinal malignancies, there are limited data as to its use in the diagnosis of lymphoproliferative disorders. Therefore, we carried out a retrospective evaluation of the performance of EUS-guided FNA combined with flow cytometry (FC) as a tool to improve overall sensitivity and specificity in the diagnosis of lymphoma. METHODS Of 1560 patients having EUS-guided FNA during the period of the study, a total of 56 patients were evaluated by cytology with FC after EUS-FNA. There was adequate material to perform FC analysis for all but one case. RESULTS EUS-FNA-FC gave a diagnosis of lymphoma in 11 cases and of reactive lymphadenopathy in 20. A specific histological type was defined by FC alone in eight cases. The remaining cases were diagnosed later by cytology and cell block sections: 13 carcinomas, nine granulomatous lymphadenopathies and one mediastinal extramedullary haematopoiesis. One case was considered only suspicious for lymphoma on cytology and FC but was not confirmed on molecular analysis and one had insufficient material for FC. CONCLUSIONS Our results show that a combination of EUS-FNA-FC is a feasible and highly accurate method, which may be used for the diagnosis and subtyping of deep-seated lymphoma, providing a significant improvement to cytomorphology alone both for diagnosis and treatment planning, as long as immunocytochemistry is available for non-lymphoma cases.
