Rapid on-site evaluation (ROSE) of image-guided FNA specimens improves subsequent core biopsy adequacy in clinical trial patients: The impact of preanalytical factors and its correlation with survival. Cancer Cytopathol 2024; 132:30-40. [PMID: 37768842 DOI: 10.1002/cncy.22764] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Revised: 07/09/2023] [Accepted: 08/02/2023] [Indexed: 09/30/2023]
Abstract
BACKGROUND Sufficient tumor collection has become of utmost importance in therapeutic experimental protocols. Rapid on-site evaluation (ROSE) ensures adequate sampling for quantification of biomarkers, molecular analyses, and other ancillary studies. The objectives of this study were to evaluate the role of ROSE in trial-associated fine-needle aspiration (FNA) and to analyze predictors of adequacy and cumulative survival from in-house FNA cases used in clinical trials. METHODS Clinical trial FNA biopsies performed at a large academic institution were analyzed over 10 months using a comprehensive chart review of the electronic medical records. SPSS version 28 was used for statistical analysis. RESULTS Three hundred twenty-five FNAs were collected for 57 clinical trials. In total, 225 individual patients had an average of 1.4 FNA procedures each as a result of a multidepartmental collaborative effort. ROSE was performed for all patients, and adequacy was evaluated by cytotechnologists. Seventy-eight percent of samples were considered adequate, 14% were considered less than optimal, and 8% were considered inadequate, with the latter two categories designated together as less than adequate. The imaging modalities were mainly ultrasound-guided (n = 267; 82%) and computed tomography-guided (n = 58; 18%). There was a statistically significant association between adequate sampling and ultrasound-guided biopsies (83%) compared with computed tomography-guided biopsies (59%; p < .01). The effect of body mass index (BMI) on mortality was also a significant finding. The authors observed a survival benefit in patients who had elevated BMIs (range, 25.0-34.9 kg/m2 ) compared with those who were underweight (BMI, <18.5 kg/m2 ) or class III obese (BMI, >35.0 kg/m2 ; p < .01). Therefore, the best predictors of adequacy and mortality were imaging modality and BMI, respectively. CONCLUSIONS Ultrasound-guided modalities are recommended for obtaining adequate FNA sampling for clinical trials. In addition, patients with cancer who had slightly elevated BMIs (25.0-34.0 kg/m2 ) had increased overall survival in this cohort.

Abstract
Intussusception in adults is a rare pathology due to the telescoping of a bowel segment into a section adjacent to it. Almost all cases are linked to a pathological lead point, which is often a colorectal carcinoma where the intussusception involves the large intestine. Likely to occur in the same clinical setting, the differential diagnosis between intussusception and colon carcinoma by ultrasound in the emergency department can be quite challenging. We present a rare case of transient colonic intussusception with a well-differentiated colon adenocarcinoma as the lead point in a 43-year-old patient. The point of care ultrasound (POCUS) revealed the target sign characteristic of intussusception at the level of maximum pain, associated with a pseudokidney sign. However, the pseudokidney sign was indeed an adenocarcinoma of the ascending colon visualized by colonoscopy and per op.

Notohara K. Biopsy diagnosis of type 1 autoimmune pancreatitis: Does it bring a conclusion or confusion? DEN OPEN 2022; 2:e82.

Abstract
A biopsy-based diagnosis of type 1 autoimmune pancreatitis (AIP) is now feasible via an endoscopic ultrasound-guided fine-needle biopsy, but there are potential issues to address. The benefits of acquiring large tissue samples include more successful immunostaining for Immunoglobulin G4 and more identifications of storiform fibrosis, obliterative phlebitis, and the ductal lesions of type 1 AIP. However, storiform fibrosis may not be present in all the type 1 AIP lesions. An interobserver agreement study revealed only slight-to-moderate agreement among pathologists diagnosing the histological findings of type 1 AIP. Potential reasons for disagreement are the different time phases of the inflammation (which result in heterogeneous histological pictures), a focal appearance of the typical histological findings, and the different definitions used by pathologists. We have thus devised guidance for diagnosing type 1 AIP based on biopsy tissues. In this guidance, we define each histological finding of type 1 AIP, for example, storiform fibrosis as a swirling arrangement of inflammatory cells, spindle-shaped cells, and delicate collagens as a unit. The necessity of elastic stains for identifying obliterative phlebitis is explained, with examples of mimickers. Another important purpose of a biopsy in type 1 AIP cases is differentiation from pancreatic ductal adenocarcinoma (PDAC). In this situation, acinar-ductal metaplasia observed in type 1 AIP is a mimicker of PDAC and should not be confused. For the resolution of potential disagreements among pathologists, a multi-disciplinary approach with the collaboration of clinicians, radiologists, and pathologists is necessary to avoid confusion.

Abstract
The purpose of this study was to describe the technique and outcomes of percutaneous thrombin injection into the superficial aspect of actively bleeding liver and kidney biopsy tracks identified with color Doppler ultrasound with the aim of hemorrhage termination. After percutaneous thrombin injection, 15/16 (94%) patients did not require further intervention. Ultrasound-guided thrombin injection into the superficial site of active bleeding is an effective technique for terminating bleeding in the immediate post-procedure period following kidney and liver biopsies and should be considered if active bleeding persists on color Doppler after ≥30 minutes of compression and observation.

Abstract
Pancreatic adenocarcinoma is a lethal disease with a mortality rate that has not significantly improved over decades. This is likely due to several challenges unique to pancreatic cancer. Most patients with pancreatic cancer are diagnosed at a late stage of disease due to the lack of specific symptoms prompting an early investigation. A small subset of patients who are diagnosed at an early stage have a better chance at survival with curative surgical resection, but most patients still succumb to the disease in a few years. The dismal overall prognosis is due to suspected micro-metastasis at an early stage. Due to this reason, there is a recent interest in treating all patients with pancreatic cancers with systemic therapy upfront (including the ones that are surgically resectable). This approach is still not the standard of care due to the lack of robust prospective data available. Recent advancements in treatment regimens of chemotherapy, radiation and immunotherapy have improved the overall short-term survival but the long-term survival still remains poor. Novel approaches in diagnosis and treatment have shown promise in clinical studies but long-term clinical data is lacking. The following manuscript presents an overview of the epidemiology, diagnosis, staging, recent advances, novel approaches and controversies in the management of pancreatic adenocarcinoma.

Abstract
Objective Both a percutaneous biopsy and endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) have been widely performed for liver tumors. However, no studies have compared these two biopsy methods. Method A retrospective study was conducted using medical records for patients who underwent a liver tumor biopsy from 2012 to 2019. The cases were classified into two groups for a comparison: an ultrasound-guided percutaneous biopsy group (percutaneous group) and an EUS-FNA group (EUS group). Results A total of 106 patients (47 in the percutaneous group and 59 in the EUS group) were included. The final diagnosis was malignant in 100 cases and benign in the remaining 6 cases. While the median lesion diameter was 62 mm in the percutaneous group, it was significantly smaller (34 mm) in the EUS group (p <0.01). The EUS group had more left lobe tumors than right lobe tumors. All cases of caudate lobe tumor (four cases) underwent EUS-FNA. The sensitivity, specificity, and accuracy of the procedure were 95%, 100%, and 96% in the percutaneous group and 100%, 100%, and 100% in the EUS group, respectively showing no significant difference. Adverse events were reported in 17% of the percutaneous group, which was significantly lower than in the EUS group (2%; p <0.01). Conclusion A percutaneous biopsy and EUS-FNA have equivalent diagnostic qualities for liver tumors, although EUS-FNA tends to be associated with fewer adverse events. A complete understanding of the characteristics of each procedure is essential when choosing the best biopsy method for each particular case.

Abstract
Background Ultrasound-guided percutaneous catheter drainage (PCD) is widely accepted as a primary treatment for pyogenic liver abscess. Severe PCD-related complications have been reported; however, delayed bleeding complications due to internal mammary artery injury are unknown. Case Presentation An 84-year-old man undergoing hemodialysis owing to chronic kidney disease due to focal segmental glomerulosclerosis was admitted to our hospital for liver cyst infection. Ultrasound-guided PCD was carried out through the normal liver at the upper abdominal midline at the level of the sixth intercostal space. Two days later, an abdominal hematoma occurred at the puncture site. Contrast-enhanced computed tomography revealed extravasation of the distal right internal mammary artery, which was successfully treated with percutaneous coil embolization. Conclusion Internal mammary artery injury should be considered as a differential diagnosis when a progressing hematoma develops after PCD.

Abstract
From May 1988 to June 1990, 260 patients with abdominal focal disease underwent ultrasonically guided percutaneous fine needle biopsy. The technique of so-called « FNAB-CYT » is described. The procedure entailed very few complications: the mortality rate was 0% and the morbidity rate was 1.5%. The specificity of the technique was 100%, and sensitivity was 93.43%. False-negative diagnoses were made in 8 cases, and in 5 patients the cytologic diagnoses were uncertain. There were no false-positives. The possibility of an immediate control of the collected material by the pathologist avoids the risk of inadequate samples and reduces the number of biopsies for the patient. Comparison among diagnoses on rapid and definitive preparations and histologic ones was carried out to evaluate the diagnostic efficiency of the cytologic procedure. In our experience, a rapid staining of the smears allowed a correct cytologic diagnosis in 87.7% of the cases within approximately 5 min of the biopsy. On the basis of our experience, the authors recommend FNAB-CYT as a routine first-level (less invasive) procedure for diagnosis of abdominal focal disease.

Abstract
Aim and background Pathological proof of malignant in biliary strictures is useful in the preoperative setting as it helps define therapeutic planning and prognosis, and reduces the length of the subsequent surgical intervention. However, it is difficult to obtain. The aim of this study was to evaluate the yield of histological and cytological examination of endobiliary samples obtained during endoscopic retrograde cholangiopancreatography (ERCP). Methods Endobiliary forceps biopsy and brush cytology were performed during ERCP examination in 52 consecutive patients, 36 with malignant and 16 with benign strictures. Results Histology and cytology turned out to have the same sensitivity (53%). The gain in sensitivity achieved by combining the two techniques was limited, reaching a value of 61%. The specificity, however, was 100% for both methods. Most of the few complications observed were due to sphincterotomy and subsided spontaneously or with medical treatment. However, one patient experienced a serious complication and chose to be treated by surgical intervention. The complication was caused by forceps biopsy. Conclusions This study shows that 1) sampling of biliary strictures during ERCP is the primary approach to tissue diagnosis; 2) brush cytology alone is sufficient in clinical practice; 3) forceps biopsy must always be used to sample intra-ampullary strictures but should be considered as a secondary step to sample strictures located more proximally, in the bile ducts, if previous cytology was negative.

Abstract
PURPOSE Perform the first in vivo examination of fine needle aspiration biopsy (FNAB) scleral tracts to determine the incidence of iatrogenic extension of tumor cells. DESIGN A prospective, consecutive, observational case series. METHODS This study was performed in a clinical/surgical setting at Retina Consultants of Houston and Houston Methodist Hospital, Houston, Texas, and included 10 patients who were scheduled for enucleation as primary treatment for uveal melanoma. Treatment included FNAB, enucleation, and histopathologic analysis. The primary outcomes were tumor location and dimension as identified by B-scans and histopathologic analysis. Tumor type was classified by gene expression profile and American Joint Committee on Cancer staging. Twenty-five- or 27-gauge needles were used for FNAB under direct visualization. Cell blocks of acquired specimens were examined using hematoxylin-eosin stain and double immunostain using HMB45 with red chromogen and Ki67 with brown 3,3'-diaminobenzidine chromogen. RESULTS Mean follow-up after enucleation was 20.4 months (range 9.9-31.7). All biopsy specimens had adequate yields for genomic analysis. No enucleation specimen contained tumor cells within sclera, pars plana, or pars plicata. One specimen contained a small collection of tumor cells within the anterior vitreous in the quadrant of the biopsy site. No patient developed an orbital recurrence. Four patients developed nonorbital metastatic uveal melanoma during the study period. Three of them died, and 1 is alive with hepatic metastasis. CONCLUSIONS No iatrogenic extension of tumor was reported. FNAB is a safe procedure that produces a high cellular yield for cytologic and genomic analyses with minimal risk of extraocular dissemination.

Abstract
Introduction. Beneath tumor grading and vascular invasion, nontumor related risk factors for HCC recurrence after liver transplantation (LT) have been postulated. Potential factors were analyzed in a large single center experience. Material and Methods. This retrospective analysis included 336 consecutive patients transplanted for HCC. The following factors were analyzed stratified for vascular invasion: immunosuppression, rejection therapy, underlying liver disease, age, gender, blood transfusions, tumor biopsy, caval replacement, waiting time, Child Pugh status, and postoperative complications. Variables with a potential prognostic impact were included in a multivariate analysis. Results. The 5- and 10-year patient survival rates were 70 and 54%. The overall 5-year recurrence rate was 48% with vascular invasion compared to 10% without (p < 0.001). Univariate analysis stratified for vascular invasion revealed age over 60, pretransplant tumor biopsy, and the application of blood transfusions as significant risk factors for tumor recurrence. Blood transfusions remained the only significant risk factor in the multivariate analysis. Recurrence occurred earlier and more frequently in correlation with the number of applied transfusions. Conclusion. Tumor related risk factors are most important and can be influenced by patient selection. However, it might be helpful to consider nontumor related risk factors, identified in the present study for further optimization of the perioperative management.

Abstract
BACKGROUND Neoplasm seeding is a serious complication after liver metastases biopsy. Reported incidences vary between 10% and 19% for colorectal cancer (CRC) and are unknown for breast cancer (BC). The aim of this retrospective study was to determine the frequency of tumor seeding after ultrasound-guided percutaneous biopsy of CRC and BC liver metastases. MATERIAL AND METHODS Unselected liver biopsies performed in the period of 2005-2012 at our institution were extracted from the National Pathology Registry. Medical records including imaging from patients with biopsy-verified BC and CRC liver metastases were retrospectively reviewed. The endpoint was the development of abdominal wall recurrence following liver biopsy. RESULTS Of total 2981 biopsies we identified 278 patients with CRC and 155 patients with BC biopsy-verified liver metastases. During the median follow-up of 25 months after biopsy (range 3-253 months), no seeding was recorded in patients with BC. Within the median follow-up of 34 months (3-111 months), seeding was registered in 17/278 (6%) of patients with CRC; three patients of 278 (1%) had undoubtedly biopsy-related seeding, which became apparent six, nine, and 26 months after biopsy, respectively; and in nine patients (3%) seeding occurred due to either biopsy or other interventions; and five patients had seeding, which were assessed as a consequence of other invasive procedures than biopsies. The median overall survival of the 17 patients with seeding was 70 months compared to 39 months of patients without seeding. CONCLUSIONS The results showed no seeding in BC patients. Seeding rate after biopsy in CRC patients is not negligible, however, without affecting outcome.

Abstract
OBJECTIVES Evaluation of enhancement characteristics of histopathologically confirmed focal nodular hyperplasias (FNHs) and hepatocellular adenomas (HCAs) with gadoxetic acid-enhanced MRI. METHODS Sixty-eight patients with 115 histopathologically proven lesions (FNHs, n=44; HCAs, n=71) examined with gadoxetic acid-enhanced MRI were retrospectively enrolled (standard of reference: surgical resection, n=53 patients (lesions: FNHs, n=37; HCAs, n=53); biopsy, n=15 (lesions: FNHs, n=7; HCAs, n=18)). Two radiologists evaluated all MR images regarding morphological features as well as the vascular and hepatocyte-specific enhancement in consensus. RESULTS For the hepatobiliary phase, relative enhancement of the lesions and lesion to liver enhancement were significantly lower for HCAs (mean, 48.7 (±48.4)%and 49.4 (±33.9) %) compared to FNHs (159.3 (±92.5) %; and 151.7 (±79) %; accuracy of 89%and 90 %, respectively; P<0.001). Visual strong uptake of FNHs vs. hypointensity of HCAs in the hepatobiliary phase resulted in an accuracy of 92 %. This parameter was superior to all other morphological and dynamic vascular criteria alone and in combination (accuracy, 54–85 %). CONCLUSIONS For differentiation of FNHs and HCAs by means of MRI, gadoxetic acid uptake in the hepatobiliary phase was found to be superior to all other criteria alone and in combination. KEY POINTS EOB-MRI is well suited to differentiate FNHs and hepatocellular adenomas. For this purpose hepatobiliary phase is superior to unenhanced and dynamic imaging. Hepatobiliary phase (peripheral) hyper- or isointensity is typical for FNH. Hepatobiliary phase hypointensity is typical for hepatocellular adenomas. EOB-MRI helps to avoid misinterpretations of benign hepatocellular lesions.

Effectiveness and complications of ultrasound guided fine needle aspiration for primary liver cancer in a Chinese population with serum α-fetoprotein levels ≤200 ng/ml--a study based on 4,312 patients. PLoS One 2014; 9:e101536. [PMID: 25170868 PMCID: PMC4149350 DOI: 10.1371/journal.pone.0101536] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2014] [Accepted: 06/07/2014] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND Hepatocellular carcinoma (HCC) can be diagnosed by noninvasive approaches with serum α-fetoprotein (AFP) levels >200 ng/ml and/or a radiological imaging study of tumor mass >2 cm in patients with chronic liver disease. Percutaneous fine needle aspiration (FNA) under ultrasound (US) guidance has a diagnostic specificity of 95% and is superior to radiological imaging studies. AIM The aim of this study is to elucidate the effectiveness and complications of fine needle aspiration in a Chinese population with primary liver cancer and AFP levels ≤200 ng/ml. MATERIALS AND METHODS A retrospective study was conducted over a period of 28 years. This selection period included patients with a suspected diagnosis of primary liver cancer whose AFP levels were ≤200 ng/ml and who underwent US-FNA. This data was then analyzed with cytomorphological features correlating with medical history, radiological imaging, AFP, and follow-up information. RESULTS Of the 1,929 cases with AFP ≤200 mg/ml, 1,756 underwent FNA. Of these, 1,590 cases were determined malignant and the remaining 166 were determined benign. Further, 1,478 malignant cases were diagnosed by FNA alone, and of these, 1,138 were diagnosed as PLC. The sensitivity, specificity, positive predictive value, negative predictive value, and overall accuracy of the diagnoses were 92.96%, 100%, 100%, 59.71%, and 93.62% respectively. There was no significant difference in the sensitivity, specificity, PPV and NPV between the subgroups with tumor size<2 cm and ≥2 cm. Major complications included implantation metastasis and hemorrhage. CONCLUSION Patients with PLC, especially those who present with an AFP ≤200 ng/ml, should undergo FNA. If negative results are obtained by FNA, it still could be HCC and repeated FNA procedure may be needed if highly suspicious of HCC on imaging study. The superiority of FNA in overall accuracy may outweigh its potential complications, such like hemorrhage and implantation metastasis.

Abstract
BACKGROUND Hepatocellular carcinoma (hcc) is one of the most common causes of cancer-related death worldwide. Overall, liver transplantation and resection are the only available treatments with potential for cure. Various locoregional therapies are widely used to manage patients with advanced hcc or as a bridging therapy for patients with early and intermediate disease. This article reviews and evaluates the role of interventional radiology in the management of such cases by assessing various aspects of each method, such as effect on rates of survival, recurrence, tumour response, and complications. METHODS A systemic search of PubMed, medline, Ovid Medline In-Process, and the Cochrane Database of Systematic Reviews retrieved all related scientific papers for review. RESULTS Needle core biopsy is a highly sensitive, specific, and accurate method for hcc grading. Portal-vein embolization provides adequate expansion of the future liver remnant, making more patients eligible for resection. In focal or multifocal unresectable early-stage disease, radiofrequency ablation tops all other thermoablative methods. However, microwave ablation is preferred in large tumours and in patients with Child-Pugh B disease. Cryoablation is preferred in recurrent disease and in patients who are poor candidates for anesthesia. Of the various transarterial modalities-transarterial chemoembolization (tace), drug-eluting beads, and transarterial radio-embolization (tare)-tace is the method of choice in Child-Pugh A disease, and tare is the method of choice in hcc cases with portal vein thrombosis. CONCLUSIONS The existing data support the importance of a multidisciplinary approach in hcc management. Large randomized controlled studies are needed to provide clear indication guidelines for each method.

Ultrasound guidance reduces pneumothorax rate and improves safety of thoracentesis in malignant pleural effusion: report on 445 consecutive patients with advanced cancer. World J Surg Oncol 2014; 12:139. [PMID: 24886486 PMCID: PMC4016786 DOI: 10.1186/1477-7819-12-139] [Citation(s) in RCA: 38] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2013] [Accepted: 04/20/2014] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Malignant pleural effusion (MPE) is an extremely common problem affecting cancer patients, and thoracentesis is an essential procedure in an attempt to delineate the etiology of the fluid collections and to relieve symptoms in affected patients. One of the most common complications of thoracentesis is pneumothorax, which has been reported to occur in 20% to 39% of thoracenteses, with 15% to 50% of patients with pneumothorax requiring tube thoracostomy.The present study was carried out to assess whether thoracenteses in cancer patients performed with ultrasound (US) guidance are associated with a lower rates of pneumothorax and tube thoracostomy than those performed without US guidance. METHODS A total of 445 patients were recruited in this retrospective study. The medical records of 445 consecutive patients with cancer and MPE evaluable for this study, undergoing thoracentesis at the Oncology-Hematology and Internal Medicine Departments, Piacenza Hospital (Italy) were reviewed. RESULTS From January 2005 to December 2011, in 310 patients (69.66%) thoracentesis was performed with US guidance and in 135 (30.34%) without it. On post-thoracentesis imaging performed in all these cases, 15 pneumothoraces (3.37%) were found; three of them (20%) required tube thoracostomy. Pneumothorax occurred in three out of 310 procedures (0.97%) performed with US guidance and in 12 of 135 procedures (8.89%) performed without it (P<0.0001). It must be emphasized that in all three patients with pneumothorax requiring tube thoracostomy, thoracentesis was performed without US guidance. CONCLUSIONS The routine use of US guidance during thoracentesis drastically reduces the rate of pneumothorax and tube thoracostomy in oncological patients, thus improving safety as demonstrated in this study.

Abstract
Needle tract seeding refers to implantation of tumor cells by contamination when instruments like biopsy needles are used to examine, excise or ablate a tumor. Implantation along needle tract may lead to change of stage of the tumor, converting a resectable tumor into an inoperable one. In this paper we have reviewed the cases of needle tract seeding due to fine needle aspiration cytology (FNAC) procedure. We analyzed the various aspects of needle tract seedling and suggested how to take precautionary measures to prevent it.

Abstract
BACKGROUND AND AIMS Endoscopical examination is not always sufficient for the diagnosis of gastrointestinal masses. This study assessed the diagnostic accuracy and safety of ultrasound-guided percutaneous biopsy of gastrointestinal lesions. METHODS This retrospective study evaluated 114 patients who underwent ultrasound-guided biopsy of gastrointestinal masses with a 18G needle. Thirty-two of these patients underwent a 22G fine-needle biopsy for cytology. Histology was compared with a composite standard of reference for diagnosis (i.e. post-surgery histological evaluation in 73 cases and computed tomography or magnetic resonance scan findings, together with a compatible clinical follow-up for at least 24 months, in the remaining 41 cases). Safety was assessed by recording side effects for up to 4h after the procedure. RESULTS Of the 114 lesions evaluated, 112 were malignant (98.2%) and 2 benign (1.8%). Specimens were adequate for histology in all but one case. Specimens were obtained from the stomach (n=38; 33.3%), small bowel (n=36; 31.6%) and colon (n=40; 35.1%). Diagnosis was correct in 113/114 cases (99.1%). Sensitivity, specificity, positive and negative predictive values, and diagnostic accuracy were 99.1%, 100%, 100%, 66%, and 99%, respectively. One of the 114 patients (0.9%) bled from a gastric GIST. CONCLUSIONS Ultrasound-guided percutaneous biopsy of gastrointestinal lesions is a valid alternative when diagnosis of a gastrointestinal mass cannot be obtained with an endoscopical procedure.

Abstract
BACKGROUND In patients with palpable hepatomegaly and space occupying lesions demonstrated by imaging techniques, blind fine needle aspiration puncture (FNAP) at the patient's bedside is feasible. OBJECTIVE To compare the diagnostic yield of the fine needle aspiration puncture (FNAP) performed blindly or under radiological control in patients with hepatomegaly and multiple solid space occupying lesions in the liver, demonstrated by ultrasonography. METHODS A retrospective study was made of 169 consecutive FNAPs of liver tumors performed either blindly at the bedside by an internist (55 patients) or imaged-guided by a radiologist (114 patients). RESULTS The diagnostic yield of the technique performed blindly to demonstrate malignancy was 78% (95% confidence interval [CI]: 66-87%) versus 83% (95% CI: 75-89%, P=.42) obtained in the image-guided FNAPs. The diagnostic yield did not vary based on type of tumor invading the liver. CONCLUSION Blind FNAP procedures in patients with palpable enlarged liver due to solid space occupying lesions is as effective as those performed under radiological control.

Abstract
PURPOSE Data yielded by transabdominal ultrasound-guided puncture techniques are valuable for determining the malignancy of inoperable mass lesions of the pancreas. In this study we analyzed the incidence of complications and the risk factors. METHODS A total of 430 punctures of the pancreas were performed for 281 patients. Risk factors were prospectively assessed and complications were recorded. All punctures were sonographically guided. RESULTS The 281 patients underwent a total of 351 puncture procedures including 430 punctures and 901 passes. The maximum diameter of the pancreatic mass lesion was documented; the mean diameter was 48.3 ± 29.1 mm. 75.8 % of punctures were performed with a needle diameter of 0.7-0.95 mm, and 23.0 % of punctures were performed as cutting biopsies producing a tissue sample 1.2 or 1.6 mm in diameter. In 77.8 % of punctures, one puncture was performed, and in 21.9 %, two punctures were performed. Three punctures were performed for one patient (0.3 %) only. The incidence of major complications was 0.3 %. None of the assessed risk factors was associated with an elevated incidence of complications. CONCLUSION Our findings demonstrate the safety of transabdominal percutaneous puncture of the pancreas but do not enable conclusions to be drawn with regard to individual risk factors.

Abstract
AIM: To assess the rate and risk factors for tumour seeding in a large cohort of patients.
METHODS: Over an 8-year period, 1436 hepatocellular carcinoma (HCC) patients with 2423 tumour nodules underwent 3015 image-guided percutaneous cryoablation sessions [1215 guided by ultrasonography and 221 by spiral computed tomography (CT)]. Follow-up CT or magnetic resonance imaging was performed every 3 mo. The detailed clinical data were recorded to analyse the risk factors for seeding.
RESULTS: The median follow-up time was 18 (range 1-90) mo. Seeding was detected in 11 patients (0.76%) at 1-24 (median 6.0) mo after cryoablation. Seeding occurred along the needle tract in 10 patients and at a distant location in 1 patient. Seeded tumours usually showed similar imaging and histopathological features to the primary HCCs. Univariate analyses identified subcapsular tumour location and direct subcapsular needle insertion as risk factors for seeding. Multivariate analysis showed that only direct subcapsular needle insertion was an independent risk factor for seeding (P = 0.017; odds ratio 2.57; 95%CI: 1.47-3.65). Seeding after cryoablation occurred earlier in patients with poorly differentiated HCC than those with well or moderately differentiated HCC [1.33 ± 0.577 mo vs 11.12 ± 6.896 mo; P = 0.042; 95%CI: (-19.115)-(-0.468)].
CONCLUSION: The risk of seeding after cryoablation for HCC is small. Direct puncture of subcapsular tumours should be avoided to minimise seeding.

Abstract
UNLABELLED Fine needle aspiration cytology is a widely accepted, reliable diagnostic modality for the early detection of metastases. OBJECTIVE Quality assurance analysis of fine needle aspiration cytology in melanoma patients. METHOD A total of 194 biopsies performed in 142 melanoma patients were analyzed retrospectively. RESULTS 138 (71.13%) cutaneous or subcutaneous nodules and 56 (28.87%) palpable lymph nodes were studied. 87 (44.85%) true positive, 92 (47.42%) true negative, 3 (1.55%) false positive and 12 (6.19%) false negative cytology results were found. High sensitivity (87.89%), specificity (96.84%) and diagnostic accuracy (93.72%) were confirmed. DISCUSSION The quality assurance of fine needle aspiration biopsy in these patients with recurrent and metastatic melanoma meets the international requirements.

Abstract
Background People often have concerns regarding tumour spread after biopsy which leads to a delay in seeking expert medical advice. The data regarding this perception is scanty. Therefore, we conducted this cross sectional study to explore the beliefs and perceptions of individuals regarding tumour spread after biopsy and the basis of those beliefs. Methods The survey was conducted in outpatient areas of two different tertiary care hospitals of Karachi namely Aga Khan University Hospital Karachi (AKUH) and Karachi Institute of Radiotherapy and Nuclear Medicine (KIRAN). We interviewed 600 individuals and documented their responses on a questionnaire. There were 400 responders from Aga Khan's Consulting Clinic and 100 each from Aga Khan's Oncology Clinic and KIRAN. Results Only 50% of the respondents chose biopsy as the best test for diagnosis of cancer. The level of education was statistically significant in making this choice of answer (p = 0.02) only in univariate analysis. Those individuals who were involved in the work up of cancer patients irrespective of their educational status gave more intelligent answers (p = 0.003). The tumour disturbance after biopsy was regarded as a major factor among 127 respondents (53%) who believed that biopsy could lead to spread of tumour. Conclusions Our study revealed that awareness regarding cancer diagnosis and biopsy is lacking among general public and it does not co-relate well with the level of formal education. These misconception and taboos need to be addressed in public seminars and in the media in order to increase the awareness which could facilitate prompt diagnosis.

Abstract
Background/Aims Needle-track seeding is a rare but important complication of diagnostic and therapeutic ultrasound (US)-guided procedures in hepatocellular carcinoma (HCC). We examined the frequency of needle-track seeding after US-guided percutaneous ethanol injection (PEI), fine-needle aspiration biopsy (FNAB), and percutaneous transhepatic biliary drainage (PTBD) in order to determine the appropriate treatment for needle-track seeding and its clinical outcome. Methods We analyzed the clinical characteristics and treatment outcomes in eight patients who experienced needle-track seeding from HCC after an US-guided procedure (FNAB, PEI, or PTBD) between January 1990 and July 2004. Results Seven (0.14%) of 5,092 patients who experienced needle-track seeding (2 after PEI, 4 after FNAB, and 1 after PTBD) during the study period and 1 other patient who experienced needle-track seeding recently were recruited for this study. Two of the eight patients underwent mass excision and the other six patients underwent en-bloc wide excision for the needle-track seeding. Tumors recurred in the needle-tracks in both patients who underwent mass excision but not in the six patients who underwent en-bloc wide excision. Mortality occurred in three patients who experienced the recurrence and progression of intrahepatic HCC. Conclusions The incidence of needle-track seeding after US-guided procedures in HCC was 0.14%. En-bloc wide excision seems to be the optimal treatment for minimizing the probability of tumor recurrence due to needle-track seeding.

Abstract
BACKGROUND Most patients with advanced cancer are frequently malnourished and frequently they develop decreased oral fluid intake and dehidratation. Home parenteral nutrition (HPN) is an increasingly used therapy for patients with advanced cancer. A central venous access device is often an essential component allowing parenteral nutrition and hidratation. However central venous catheter (CVC) insertion represents a risk for pneumothorax or other mechanical complications. This study aimed to determine the reduction of risks related to central venous catheter positionement in the setting of cancer patients with palliative programm. METHODS Consecutive patients with a variety of cancer in advanced phase requiring palliative care who were undergoing placement of central venous catheter for parenteral nutrition or hydratation have been prospectively studied in a program of ultrasound-guided CVC placement. Four types of possible complications were defined:mechanical, thrombotic, infection and malfunctioning. After sterilization, local anesthesia is applied and a 7.5 MHZ puncturing US probe is placed in the supraclavicular site and a 16-gauge needle is advanced under real-time US guidance, into the last portion of internal jugular vein by experienced physicians. The Seldinger tecnique is used to place the catheter that is advanced into the superior vena cava until insertion to right atrium. Two hours after each procedure a chest X-ray and US scanning are carried out to confirm CVC position and rule out a pneumotorax. RESULTS From 30 October 2000 to 31 October 2008: 209 CVC insertional procedure were applied in 207 patients with cancer in the palliative phase only. There were 101 women and 106 men with a mean age of 67.68 year (range 22-86). A single needle puncture of the vein was performed on 206 of 209 procedures (98.6%), the technique was efficacious at the first attempt in 98.6% of cases, in 2 patients (0.96%) the CVC was positioned at the second attempt. The procedure failed only one case (0.44%). No cases of pneumothorax, of major bleeding or nerve punctured were reported. Symptomatic vein thrombosis developed in one patient (0.44%). Infection episodes were reported in two cases. Mean time for CVC permanence was 92.5±9.1 days (range 8-158). CONCLUSION This study indicates that US-guided CVC insertion is a safe, cheap procedure for cancer patients in advanced phase and with palliative program, allowing parenteral nutrition and hydratation.

Abstract
The role of fine needle aspiration (FNA) biopsy of the liver has evolved. Advances in imaging modalities have obviated the need for tissue confirmation in clinically classic hepatocellular carcinoma (HCC). The risks of needle tract seeding and haematogenous dissemination have been actively debated. Nowadays, cytopathologists are confronted by smaller and smaller nodules, detected due to increased surveillance of high-risk cirrhotic patients. Tissue characterization of small well-differentiated hepatocellular nodular lesions (size less than and equal to 2 cm) is extremely challenging and has therapeutic implications. Major issues in the cytodiagnosis of HCC include: (i) distinguishing benign hepatocellular nodular lesions, namely, large regenerative nodules, dysplastic nodules, focal nodular hyperplasia and hepatocellular adenoma from reactive hepatocytes; (ii) distinguishing well-differentiated HCC from benign hepatocellular nodular lesions; (iii) distinguishing poorly differentiated HCC from intrahepatic cholangiocarcinoma and metastatic carcinomas; (iv) determining the histogenesis of a malignant tumour; and (v) determining the site of origin of a malignant tumour. An overview of the biological evolution and histopathological aspects of dysplastic nodules, small HCCs and 'nodule-in-nodule' lesions is presented in tandem with clinically relevant nomenclature. An algorithmic approach to FNA diagnosis of HCC and hepatocellular nodular lesions is outlined. Optimal results depend on (i) a dedicated radiologist-cytopathologist team; (ii) an on-site cytology service, (iii) a combined cytohistological approach, (iv) immunohistochemistry, and (v) clinicopathological correlation. As we move towards personalized medicine, it is envisaged that hepatic FNA is likely to become a point of care in the management protocol as it takes on the additional role of procurement of tumour and peritumoural tissues for genomic and proteomic profiling to enable targeted molecular therapy.

Abstract
The role of hepatic fine-needle aspiration (FNA) biopsy has evolved. Advances in imaging modalities have obviated the need for tissue confirmation in most hepatocellular carcinomas (HCCs). There is risk of needle-tract seeding. Increasingly, small nodules are being detected on ultrasound surveillance of high-risk patients. Diagnostic challenges associated with cirrhosis include distinction of benign hepatocellular nodules, namely, large regenerative nodules and dysplastic nodules, from reactive hepatocytes; and distinction of well-differentiated HCCs from benign hepatocellular nodules. This paper will discuss (i) controversies regarding preoperative/pretransplantation FNA diagnosis of HCC, (ii) update of biological evolution, nomenclature, and histopathologic criteria for diagnosis of precancerous nodules and small HCCs, and (iii) algorithmic approach to FNA diagnosis of hepatocellular nodules. Optimal results depend on dedicated radiologist-cytopathologist team, on-site cytology service; combined cytohistologic approach, immunohistochemistry, and clinicopathologic correlation. Hepatic FNA is likely to be incorporated as a point of care as we move towards personalized medicine.

Abstract
Peritoneal seeding (PS) of hepatocellular carcinoma (HCC) is uncommon, and the clinicopathological features are poorly understood. A total of 181 autopsy cases of HCC, including 171 cases with detailed clinical information, was investigated for PS and evaluated. PS was identified in 17 cases (9.4%), and was locally (70.6%) or entirely (29.4%) distributed in the peritoneal cavity, involving the diaphragm (76.5%), omentum (47.1%), or alimentary tract serosa (47.1%). Compared with primary HCC, PS showed similar or slightly undifferentiated features (88.2%) and exhibited more differentiated features (11.8%). In 15 cases (88.2%) of HCC with PS, primary HCC showed membranous β-catenin immunoreactivity. However, in five cases (33.3%), respective PS lost this immunoreactivity. PS was significantly associated with rupture of HCC (P= 0.012), direct diaphragmatic invasion (P= 0.001), and lymph node metastasis (P < 0.001), indicating these are high risk factors for PS; there was no significant association with a past history of percutaneous fine-needle biopsy, percutaneous ethanol injection and/or radiofrequency ablation (P= 0.97), or metastasis to lung (P= 0.13), bone (P= 0.71), or adrenal gland (P= 0.79). PS can infrequently proliferate aggressively with more differentiated features. Loss of membranous β-catenin expression may be associated with PS of HCC.

Abstract
BACKGROUND A central venous catheter (CVC) currently represents the most frequently adopted intravenous line for patients undergoing infusional chemotherapy and/or high-dose chemotherapy with hematopoietic stem-cell transplantation and parenteral nutrition. CVC insertion represents a risk for pneumothorax, nerve or arterial punctures. The aim of this prospective observational study was to explore the safety and efficacy of CVC insertion under ultrasound (US) guidance and to confirm its utility in clinical practice in cancer patients. METHODS Consecutive adult patients attending the oncology-hematology department were eligible if they had solid or hematologic malignancies and required CVC insertion. Four types of possible complication were defined a priore: mechanical, thrombotic, infection and malfunctioning. The patient was placed in Trendelenburg's position, a 7.5 MHZ puncturing US probe was placed in the supraclavicular site and a 16-gauge needle was advanced under real-time US guidance into the last portion of internal jugular vein. The Seldinger technique was used to place the catheter, which was advanced into the superior vena cava until insertion into right atrium. Within two hours after each procedure, an upright chest X-ray and ultrasound scanning were carried out to confirm the CVC position and to rule out a pneumotorax. CVC-related infections, symptomatic vein thrombosis and malfunctioning were recorded. RESULTS From December 2000 to January 2009, 1,978 CVC insertional procedures were applied to 1,660 consecutive patients. The procedure was performed 580 times in patients with hematologic malignancies and 1,398 times those with solid tumors. A single-needle puncture of the vein was performed on 1,948 of 1,978 procedures (98.48%); only eighteen attempts among 1,978 failed (0.9%). No pneumotorax, no major bleeding, and no nerve puncture were reported; four cases (0.2%) showed self-limiting hematomas. The mean lifespan of CVC was 189.7 +/- 18.6 days (range 7-701). Symptomatic deep-vein thrombosis of the upper limbs developed in 48 patients (2.42%). Catheter-related infections occurred in 197 (9.96%) of the catheters inserted. They were successfully treated with antibiotics and only in 48 (2.9%) patients definitive CVC removal was required for infection and/or thrombosis or malfunctioning. CONCLUSIONS This study represents the largest published series of consecutive patients with cancer undergoing CVC insertion under US guidance; this procedure allowed the completion of the therapeutic program for 1,930/1,978 (97.6%) of the catheters inserted. The absence of pneumotorax and other major complications indicates that US guidance should be mandatory for CVC insertion in patients with cancer.

Abstract
AIM: To investigate the serological diagnostic factors for liver metastasis in patients with colorectal cancer.
METHODS: One hundred and six adult in-patients with colorectal cancer were studied and divided into patients with liver metastasis (n = 56) and patients without liver metastasis (n = 50). Serum levels of tumor and biochemical markers for liver were measured at the time of diagnosis.
RESULTS: The mean survival time was 55.9 mo, 36.8 mo and 68.3 mo for the overall patients, patients with liver metastasis and patients without liver metastasis, respectively. Lactate dehydrogenase (LDH) level was significantly correlated with the survival time of colorectal cancer patients. The levels of alanine aminotransferase, aspartate aminotransferase, γ-glutamyltransferase (GGT), LDH and carcinoembryonic antigen (CEA) were significantly higher in patients with liver metastasis than in those without liver metastasis. Patients with lymph node metastasis had a higher risk of liver metastasis than those without lymph node metastasis. The cut points of LDH, GGT and CEA for screening liver metastasis were 180 U/L, 30 U/L and 5.0 μg/L, respectively. The sensitivity was 64.3%, 69.6% and 70.4%, and the specificity was 64.0%, 60.0% and 52.4%, respectively. The sensitivity of parallel test was 85.2% for LDH and CEA, and 92.6% for GGT and CEA, respectively. The specificity of serial test was 85.7% for LDH (or GGT) and CEA.
CONCLUSION: Early diagnosis of liver metastasis is of great significance. The sensitivity and specificity of combined tumor and biochemical markers are rather good in screening colorectal liver metastasis.

Abstract
OBJECTIVE The objective of our study was to report the incidence of bleeding after imaging-guided percutaneous core biopsy at a single center using a standardized technique. MATERIALS AND METHODS We performed a retrospective review of percutaneous core biopsies performed at our institution from January 2002 through February 2008. Data were collected at the time of biopsy, and clinical information was obtained 24 hours and 3 months after the biopsy. The specific information that was collected included the results of coagulation studies, aspirin use, the organ biopsied, the size of the biopsy needle, and the number of needle passes. Bleeding complications were defined using the Common Terminology Criteria for Adverse Events (CTCAE, version 3.0) established by the National Cancer Institute. RESULTS Among the 15,181 percutaneous core biopsies performed during the study period, 70 hemorrhages (0.5%) that were CTCAE grade 3 or greater were identified within 3 months of biopsy. The incidence of bleeding in patients taking aspirin within 10 days before biopsy was 0.6% (18/3,195), which was not statistically different compared with the incidence of bleeding in those not taking aspirin (52/11,986, 0.4%; p = 0.34). The incidence of bleeding after liver biopsy was 0.5%; kidney biopsy, 0.7%; lung biopsy, 0.2%; pancreas biopsy, 1.0%; and other biopsy, 0.2%. There were significant associations between major bleeding and serum platelet count and international normalized ratio (p < 0.001), although the association between major bleeding and the size of the biopsy needle was not significant (p = 0.97). CONCLUSION The overall incidence of major bleeding after imaging-guided percutaneous core needle biopsy is low. Recent aspirin therapy does not appear to significantly increase the risk of such bleeding complications.

Abstract
Due to the widespread clinical use of imaging modalities such as ultrasonography, computed tomography and magnetic resonance imaging (MRI), previously unsuspected liver masses are increasingly being found in asymptomatic patients. This review discusses the various characteristics of the most common solid liver lesions and recommends a practical approach for diagnostic workup. Likely diagnoses include hepatocellular carcinoma (the most likely; a solid liver lesion in a cirrhotic liver) and hemangioma (generally presenting as a mass in a non-cirrhotic liver). Focal nodular hyperplasia and hepatic adenoma should be ruled out in young women. In 70% of cases, MRI with gadolinium differentiates between these lesions. Fine needle core biopsy or aspiration, or both, might be required in doubtful cases. If uncertainty persists as to the nature of the lesion, surgical resection is recommended. If the patient is known to have a primary malignancy and the lesion was found at tumor staging or follow up, histology is required only when the nature of the liver lesion is doubtful.

Abstract
AIM To determine the diagnostic value and major complications of fine-needle aspiration (FNA) for primary liver cancer (PLC) and its influence on the treatment outcome and prognosis. METHODS Information was gathered retrospectively for 3011 patients who presented with suspected PLC. Of which 2528 cases underwent ultrasound-guided fine-needle aspiration (US-FNA) biopsy. Patients were followed up through repeated office visits and imaging studies with a median follow-up of 7 months (range, 1-29 months). RESULTS The sensitivity, specificity, positive predictive value, negative predictive value and overall accuracy of cytological diagnosis by FNA biopsy for detection of liver malignancy were 91.5%, 100.0%, 100.00%, 59.1% and 92.4% respectively. All patients with AFP> or = 400 microg/L were associated with malignancy. Of 1154 patients with AFP<400 microg/L who were finally proved PLC, 945 were detected by FNA alone. Major complications included bleeding in 11 cases (5 of them died later), occurred mainly in hepatocellular carcinoma with superficial location, large tumors and severe cirrhosis, and implantation metastases in 5 cases, which were recognized as a subcutaneous nodule at the previous biopsy site. Implantation metastases were treated with resection or radiotherapy. CONCLUSION FNA biopsy is valuable for the diagnosis of PLC. However, complications of post-biopsy hemorrhage should not be ignored, as such bleeding may be fatal. Implantation seems to have little effect on the prognosis.

Abstract
Since its advent more than 20 years ago, endoscopic ultrasound (EUS) has undergone evolution from an experimental to a diagnostic instrument and is now established as a therapeutic tool for endoscopists. Endoscopic ultrasound cannot accurately distinguish benign from malignant changes in the primary lesion or lymph node on imaging alone. With the introduction of the curved linear array echoendoscope in the 1990s, the indications for EUS have expanded. The curved linear array echoendoscope enables the visualization of a needle as it exits from the biopsy channel in the same plane of ultrasound imaging in real time. This allows the endoscopist to perform a whole range of interventional applications ranging from fine needle aspiration (FNA) of lesions surrounding the gastrointestinal tract to celiac plexus block and drainage of pancreatic pseudocyst. This article reviews the current role of EUS and EUS-FNA in diagnosis, staging and interventional application of solid pancreatic cancer.

Abstract
Pancreatic cancer is the 4th leading cause of cancer death annually. Recent technological advances in imaging have led to non-uniformity in the evaluation of pancreatic neoplasms. The following article describes the history behind various biopsy techniques and the rationale for obtaining a biopsy of a pancreatic neoplasm and discusses the benefits and disadvantages of the various pancreatic biopsy techniques, including fine needle aspiration biopsy, Tru-cut needle biopsy, endoscopic brushings/cytology, and endoscopic ultrasound guided biopsies. A treatment algorithm for pancreatic neoplasms is then presented.

Savoy AD, Raimondo M, Woodward TA, Noh K, Pungpapong S, Jones AD, Crook J, Wallace MB. Can endosonographers evaluate on-site cytologic adequacy? A comparison with cytotechnologists. Gastrointest Endosc 2007; 65:953-7. [PMID: 17531627 DOI: 10.1016/j.gie.2006.11.014] [Citation(s) in RCA: 68] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/17/2005] [Accepted: 11/04/2006] [Indexed: 12/13/2022]
Abstract
BACKGROUND On-site determination of cytologic adequacy increases the accuracy of EUS-guided FNA (EUS-FNA); however, on-site cytotechnologists are not available to all endosonographers. We hypothesize that experienced endosonographers can accurately assess whether an on-site FNA specimen is adequate. OBJECTIVE To determine the accuracy of on-site cytopathology interpretation of EUS-FNA specimens by comparing endosonographers with a cytotechnologist. DESIGN Prospective double-blind controlled trial. SETTING Academic medical center with a high-volume EUS practice. PATIENTS Consecutive patients undergoing EUS-FNA of lymph nodes or pancreas tumors. MAIN OUTCOME MEASUREMENTS Accuracy, sensitivity, and specificity of 3 endosonographers and 1 cytotechnologist for interpretation of cytologic specimen adequacy and diagnosis compared with a criterion standard of a board-certified cytopathologist. RESULTS There were 59 lymph node, 49 pancreas, and 9 liver specimens (117 total). For determination of adequacy, none of the endosonographers were statistically equivalent to the cytotechnologist (P=.004). For determination of suspicious/malignant versus benign specimens, all 3 endosonographers were inferior (P<.001) to the cytotechnologist. LIMITATIONS This study represents a small group of trained endosonographers in a high-volume practice and may not be applicable to other settings. The sample size does not allow an accurate evaluation of different biopsy sites (eg, pancreas vs lymph node). CONCLUSIONS Even trained endosonographers have variable and, in some cases, inferior abilities to interpret on-site cytologic adequacy compared with cytotechnologists.

Seeding risk for percutaneous approach of HCC. Cancer Treat Rev 2007; 33:437-47. [PMID: 17512669 DOI: 10.1016/j.ctrv.2007.04.001] [Citation(s) in RCA: 208] [Impact Index Per Article: 12.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2006] [Revised: 03/30/2007] [Accepted: 04/03/2007] [Indexed: 02/06/2023]
Abstract
BACKGROUND Tumour biopsy is usually considered mandatory for patient management by oncologists. Currently percutaneous ablation is used therapeutically for cirrhotic patients with small hepatocellular carcinoma (HCC), not suitable for resection or waiting for liver transplantation. However malignant seeding is a recognized complication of both diagnostic and therapeutic procedures in patients with HCC. Although percutaneous therapy whether with or without biopsy of a suspected HCC nodule may minimize the risk of seeding, this has not been confirmed. AIM To evaluate the risk of seeding, defined as new neoplastic disease occurring outside the liver capsule, either in the subcutaneous tissue or peritoneal cavity following needle biopsy and/or local ablation therapy (LAT). METHODS A literature search resulted in 179 events in 99 articles between January 1983 and February 2007: 66 seedings followed liver biopsy, 26 percutaneous ethanol injection (PEI), 1 microwave, 22 radiofrequency ablation (RFA), and 64 after combined biopsy and percutaneous treatment (5 microwave; 33 PEI; 26 RFA). RESULTS In 41 papers specifying the total number of patients biopsied and/or treated, the median risk of seeding was 2.29% (range 0-11%) for biopsy group; 1.4% (1.15-1.85%) for PEI when used with biopsy and 0.61% (0-5.56%) for RFA without biopsy, 0.95% (0-12.5%) for RFA with biopsy and 0.72% (0-10%) for liver nodules (including non-HCC nodules) biopsied and ablated. CONCLUSION Risk of seeding with HCC is substantial and appears greater with using diagnostic biopsy alone compared to therapeutic percutaneous procedures. This risk is particularly relevant for patients being considered for liver transplantation.

Abstract
BACKGROUND Sentinel lymph node biopsy (SLNB) allows early detection of metastases, thereby enabling early treatment in melanoma patients likely to benefit from adjuvant therapies. This prospective study analyzes the possible benefits of additional ultrasound (US) and fine needle aspiration cytology (FNAC) of sentinel nodes (SN) prior to SLNB. METHOD Over a 2-year period 127 melanoma patients with 151 SN were scheduled for SLNB. All SN were initially identified with lymphoscintigraphy, then identified and evaluated by US and the cells aspirated for cytology (FNAC). US findings and FNAC results were compared to surgical findings. RESULTS Of 127 patients, 114 had one SN each, 12 had two, and one had three. In vivo US achieved a sensitivity of 79% (95% CI: 62-91%) and a specificity of 72% (95% CI: 62-81%). FNAC showed a sensitivity of 59% (95% CI: 41-76%) and a specificity of 100% (95% CI: 95-100%). The combination of these two in vivo methods achieved an overall sensitivity of 82% (95% CI: 65-93%) and an overall specificity of 72% [95% CI: 62-81%]. CONCLUSION Combined US and FNAC provides important information prior to SLNB in that both procedures identify metastases in the lymph nodes (sensitivity > 80%). Patients with positive FNAC may proceed directly to complete lymph node dissection (cLND) instead of having initial SLNB. Thus, combined US and FNAC may prevent unnecessary anesthesia and surgical management as well reduce costs. In our study 16% (19/121) fewer SLNB procedures were carried out, subsequently replaced by cLND. For patients with a negative combination of in vivo US and FNAC, SLNB remains the best diagnostic option.

Abstract
This review discusses the current imaging modalities for the diagnosis and staging of solid and cystic pancreatic lesions and for the assessment of acute and chronic pancreatitis, and the future role of emerging technologies in the management of pancreatic diseases. Multidetector row spiral computed tomography is superior to conventional single-detector row spiral computed tomography in the detection and staging of pancreatic adenocarcinoma. Positron emission tomography is a sensitive but relatively nonspecific diagnostic modality. Positron emission tomography-computed tomography fusion may improve the staging accuracy for pancreatic cancer. Echo-enhanced ultrasound may have an emerging role in evaluating pancreatic masses. Endoscopic ultrasound with fine needle aspiration for cytology is the single best method for diagnosis and staging of nonmetastatic pancreatic cancer with a high accuracy for determining tumor resectability. In acute pancreatitis, a modification of the standard computed tomography severity index, which places greater emphasis on extrapancreatic complications, has shown superior correlation with various patient outcome measures. Endoscopic retrograde cholangiopancreatography is still the test of choice for morphological evaluation of chronic pancreatitis, whereas magnetic resonance cholangiopancreatography offers a noninvasive alternative in selected patients. Endoscopic ultrasound can be useful for detecting early chronic pancreatitis. Secretin-stimulated imaging techniques may eventually provide a noninvasive method of reliably assessing pancreatic exocrine function.

Abstract
AIMS To review the latest strategies and controversies in the surgical treatment of liver metastases of colorectal cancer systemically and comprehensively. METHODS A medline based literature search on relevant topics was performed in PubMed for key articles concerning the novel strategies and controversies in the management of liver metastases of colorectal cancer. Some information was obtained from 'Proc Am Soc Clin Oncol' published recently. The findings and discussions were related to our own experiences. RESULTS Although for well-indicated patients, a consensus has been reached that hepatic resection is the only management that could provide the patients curability, there still exist many controversies, such as the prognostic evaluation, contraindications to hepatic resection, treatment for synchronous liver metastases, the place of laparoscopic surgery, etc. Meanwhile, various strategies to improve the respectabilities are available, including neoadjuvant chemotherapy, portal vein embolization, two stage hepatectomy, and some locally ablative approaches. The current condition is difficult and sometimes confusing for a relevant surgeon when designing treatment protocols for more complex diseases. CONCLUSION As the advancing of the management of liver metastases of colorectal cancer, more patients will become candidates for and benefit from potentially curative surgical resections. Optimal effect could only be achieved when used in a manner tailored to the individual patient.

Abstract
BACKGROUND Evaluation of a focal pancreatic mass in the setting of chronic pancreatitis (CP) is a diagnostic challenge. The objectives of the study were to compare the diagnostic yield and accuracy of EUS-guided FNA (EUS-FNA) in the evaluation of pancreatic-mass lesions in the presence or the absence of CP and to identify predictors of CP before EUS-FNA of pancreatic-mass lesions. METHODS The study design was analysis of data collected prospectively on all patients with solid pancreatic-mass lesions who underwent EUS-FNA at a tertiary referral center. A total of 282 consecutive patients underwent 300 EUS-FNA procedures of pancreatic-mass lesions over a 3-year period. The diagnostic yield and the accuracy of EUS-FNA was compared between patients with and without CP. CP was defined by the presence of more than 4 EUS criteria. RESULTS Final diagnosis was adenocarcinoma in 210 (70%), benign disease in 64 (21%), other pathology in 19 (6%), and indeterminate in 4 (2%); 3 patients (1%) were lost to follow-up. CP was noted in 75/300 (25%) patients. A lower sensitivity for EUS-FNA was observed in patients with CP than in those without CP (73.9% vs. 91.3%; p = 0.02). While patients with CP had a higher negative predictive value (88.9% vs. 45.5%; p < 0.001), no significant differences were observed for specificity (100% vs. 93.8%), positive predictive value (100% vs. 99.5%), and accuracy (91.5% vs. 91.4%) between those with and without CP. False-negative cytology was encountered in 24 cases: 6/71 (8%) with CP vs. 18/222 (8%) without CP. Patients with CP required more EUS-FNA passes to establish a diagnosis vs. those without CP (median, 5 vs. 2; p < 0.001). On multivariable analysis, age < 50 years (p < 0.001), male gender (p < 0.001), black race (p = 0.001), and the absence of jaundice (p = 0.005) were significantly associated with CP. The impact of EUS-FNA on long-term clinical management was not analyzed. The impact of individual EUS features of CP on sensitivity of EUS-FNA was not evaluated. By protocol, mass lesions that were benign required more passes to definitively exclude malignancy. CONCLUSIONS EUS-FNA has a low sensitivity for pancreatic-mass lesions in the setting of CP. This decreased sensitivity can be overcome by performing more numbers of passes at FNA, which improves diagnostic accuracy. Demographic features and clinical presentation are predictive of underlying CP in patients with pancreatic-mass lesions.

Abstract
Endosonography ultrasound (EUS) is a minimally invasive technology using a high-frequency ultrasound transducer that is incorporated into the tip of a conventional endoscope. This technique permits high-resolution imaging of the gastrointestinal wall and structures in its vicinity, as well as real-time endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA). This is a review of the literature on EUS-guided FNA of the mediastinal and abdominal lymph nodes, the pancreas, intramural gastrointestinal masses, and other miscellaneous organs and body cavities. EUS-guided FNA is a recently developed procedure that has established itself as a safe, highly accurate, and clinically useful modality.

Abstract
BACKGROUND Endoscopic ultrasonography-guided fine-needle aspiration biopsy (EUS-FNAB) has come into widespread use, mainly in Western countries, as an efficient and safe method for the cytologic or histologic diagnosis of pancreatic cancer. However, it still has received relatively little attention in Japan. To evaluate the clinical status of EUS-FNAB in Japan, we retrospectively analyzed the results with regard to the ability of EUS-FNAB to diagnose pancreatic cancer, as well as its safety. METHODS A total of 52 patients (37 male, 15 female; mean age, 62.5 years; range, 33-85 years) with focal pancreatic lesions underwent EUS-FNAB at our group of hospitals in one region of Japan. Final diagnosis was confirmed by histologic examination of surgical specimens or clinical follow-up. RESULTS The final diagnoses were malignant tumors in 32 patients and benign ones in 20. Insertion of the needle into the lesion was successful in 50 of the 52 patients (96.2%). Adequate specimens were obtained by EUS-FNAB from 47 of the 50 pancreatic lesions (94.0%). With five false-negative and no false-positive results, the accuracy, sensitivity, specificity, and positive and negative predictive values were 89.4%, 82.1%, 100%, 100%, and 79.2%, respectively. No complications occurred. CONCLUSIONS EUS-FNAB is an efficient and safe method for the histologic diagnosis of pancreatic cancer. It should be considered as one of the indispensable modalities for the histological diagnosis of pancreatic cancer in Japan, as it is in Western countries.
