Needle Aspiration Cytology

Objective: The rate of pancreatic lesions has increased in recent decades due to the widespread use of advanced imaging techniques. Nowadays, a significant proportion of cases are incidentally discovered in asymptomatic patients and cytology is an important tool for the diagnosis and multidisciplinary management of these cases. Study Design: In this study we retrospectively review the experience with pancreatic fine-needle aspiration cytology in the last 17 years at a single large tertiary hospital in Madrid, Spain. Results: Our results indicate that more than 60% of pancreatic malignant lesions are cytologically confirmed before surgery and 30% of the patients are asymptomatic. Despite this, we have noted that the total number of malignant lesions surgically resected in our hospital has basically remained unchanged over the years, because incidental diagnosis is not always synonymous with resectability and a substantial number of patients are already metastatic at the time of diagnosis. Our series also shows an increase in the number of neuroendocrine tumors, which now represent almost 20% of all cytological diagnoses at our hospital. The sensitivity in our series is 70% and the false negative rate remains 30%, despite sample quality control by experienced cytologists and standardized technical conditions. Fibrosis and necrosis are the 2 features of the primary tumor that significantly and negatively influence the accuracy of cytologic diagnosis. Conclusion: We herein report our experience with cytologic diagnosis of pancreatic lesions in a single tertiary hospital. Our results confirm that cytology is a safe, reliable, and important tool for pancreatic lesion diagnosis and management.

INTRODUCTION: The study is an attempt to evaluate the sensitivity, specificity, positive predictive value, negative predictive value, p Value and complications of CT guided thoracic interventions fine needle aspiration cytology and core biopsy which are used for diagnosing benign and malignant thoracic lesions. MATERIAL AND METHODS: Study included 102 Patients (87 males and 15 females) with age group ranged from 15 to 87 years.A total of 143 CT guided interventions (84 FNAC’s and 59 core biopsies) were performed in 102 patients. The tissue obtained was sent to the laboratory for histopathological and cytological analysis for a final diagnosis which would contribute to patient management. RESULTS: All( 59) core biopsies were successful in procuring adequate tissue for histopathological analysis and the yield of core biopsies was 100% .However out of 84 FNAC’s only 4 were unsuccessful in procuring adequate tissue with a failure rate of 4.8%. Post procedural biopsy complications were only three (2.1%) which were small pneumothorax. There were 75 malignant lesions and 23 benign lesions based on cytology and histopathology (4 were excluded due to inadequate sample). There was good agreement between benign and malignant lesions diagnosed on CT and that diagnosed by pathology. The most common benign and malignant lesions were granulomatous lesion and squamous cell carcinoma. CONCLUSION: Percutaneous CT guided interventions like core biopsy and fine needle aspirations cytology are simple minimal invasive procedures with good patient acceptance and low morbidity and almost negligible mortality. CT guided interventions should be performed early for diagnosis of thoracic lesions.

Background: Fine needle aspiration cytology (FNAC) is used as a diagnostic tool for masses or lumps. Ultrasound-guided FNAC is usually used for the diagnosis of hepatic lesions. Aim: To analyze the role of ultrasound-guided fine needle aspiration cytology in the differentiation of hepatic lesions in benign and malignant lesions. Methods: During one year total 83 cases were selected and their FNAC was performed. Cases were analyzed after routine staining. Cell blocks were prepared where blood stained material was aspirated. Results: Mean age of the patients was 52±7.8 years and M: F of 1.3:1. 8 cases (9.64%) had low cellularity smear, 18 cases (21.69%) were of benign origin and 57 cases (68.67%) revealed malignant lesions, eight cases (9.64%) were of primary origin and 51 cases (59.03%) were of secondary origin. Conclusion: Ultrasound-guided FNAC is a useful and accurate method and can be used for diagnosis of different kinds of hepatic lesions.

AbstractThe usefulness of fine-needle aspiration cytology (FNAC) in the diagnosis and treatment of submandibular gland lesions is not well known. The 210 FNACs taken from submandibular gland lesions at Turku University Central Hospital between 1984 and 1991 were reviewed. Of these FNACs, 78 samples from primary lesions were confirmed histologically. Within this subset 10 FNACs were taken from benign neoplasms, all of which were correctly classified (sensitivity 100 per cent; specificity 88 percent). Only four of the 14 FNACs from malignant lesions were cytologically considered malignant (sensitivity 29 per cent). On the other hand, four FNACs raised a false suspicion of malignancy (specificity 6 per cent). Out of 54 FNACs from non-neoplastic lesions 43 were correct (sensitivity 80 per cent; specificity 63 per cent). There were 104 patients (123 FNACs), who had not been operated on: the follow-up of these patients shows that in this subset of FNACs there were no false malignant but probably one false benign finding (1 per cent). We conclude that FNAC can offer valuable information about the type of the submandibular gland lesion, but the decision of operative and other treatment should not be based solely on the result of FNAC.
