Fine needle aspiration at a Regional Head and Neck Clinic: a clinically beneficial and cost-effective service.
ABSTRACT Fine needle aspiration (FNA) is an important adjuvant to the diagnosis of a palpable lesion which often permits the complete assessment of patients. The main objective of this study was to determine the clinical benefit of a dedicated FNA service at a tertiary referral Head and Neck Clinic and to assess if such a service is cost effective.
All patients attending the Head and Neck Clinic during 2004 were prospectively assessed in this study. Patient records were analysed regarding investigative modalities including FNA, the subsequent cytology result and the requirement for further histopathological investigations. A cost analysis for all investigative procedures was performed.
A total of 135 patients (36 males) had FNAs performed during the study period. The median age was 51.5 years (range 17-92). Patients presented with lesions of lymph nodes (n = 46), thyroid (n = 41), salivary, parotid or submandibular glands (n = 22) and other cutaneous or cystic lesions (n = 26). Cytological grading results were; C1 = 26, C2 = 93, C3 = 8, C4 = 2 and C5 = 6. Patients with lesions C3 or above normally proceeded to further investigations. The overall cost of the FNA per episode in the out-patient clinic was pound114 per episode compared to day case open biopsy per patient of pound333 and an in-patient stay per patient was pound2371. FNA provided sufficient pathological diagnosis to avoid day case surgery in 57 patients (42.2%), and inpatient surgery in 65 patients (48.1%) resulting in a total saving of pound158 372 in 2004.
This study demonstrates the clinical benefit and cost-effectiveness of FNA services in a dedicated Head and Neck clinic.

ABSTRACT: In ENT clinical practice patients with neck swelling is a common presentation. To know their exact nature a simple, sensitive and diagnostic tool is required to prevent unnecessary costlier investigation and corresponding treatment. Fine needle aspiration cytology (FNAC) is a very safe, sensitive and diagnostic tool. This study was done to know the diagnostic accuracy, sensitivity and specificity of the FNAC in head and neck masses. Present prospective study was done in 179 patients of head and neck masses which were subjected to FNAC and their results were later correlated with histopathological examination report (HPR) wherever available. Out of 179 FNAC, HPR available only in 152 cases. In present study 104 cases (58.10 %) of lymph node, 35 cases (19.55 %) of thyroid gland, 17 cases (9.49 %) of salivary gland, 12 cases (6.70 %) of soft tissue and 11 cases (6.14 %) of miscellaneous swellings were present. The sensitivity, specificity, positive predictive value and negative predictive value of present study were 81.8, 95.0, 81.8 and 95.0 % respectively. The accuracy was 92.10 %.Indian Journal of Otolaryngology and Head & Neck Surgery 06/2014; 66(2). DOI:10.1007/s12070-014-0709-3 · 0.05 Impact Factor

ABSTRACT: Palpable lesion(s) noticed in a patient with thoracic disease may be a useful diagnostic tool and it often gives a clue for further management. In this study, we searched the diagnostic value of palpable lesions in patients with thoracic pathology suspected clinically and/or radiologically. We prospectively examined the correlations of clinical/radiologic and pathologic findings of 72 palpable lesions from 68 patients who presented with suspect for a thoracic disease from two tertiary medical centers. Thirty-two lesions (44.4%) were diagnosed as malignant either by fine-needle aspiration (FNA) only or FNA with confirmatory biopsy. The most common malignancy was non-small-cell carcinoma (10) followed by adenocarcinoma (6), and small-cell carcinoma (5). The most common localization of the palpable lesions was cervical region (20.8%) followed by left supraclavicular (13.8%) and anterior chest wall (13.8%). FNA was effective in obtaining an accurate diagnosis in 66.6% of the patients. Tissue confirmation of FNA was performed in 54 patients. The sensitivity, specificity, negative predictive value, and positive predictive value of FNA in distinguishing a malignant lesion from a benign disease for these palpable lesions were 75, 97, 96, and 80, respectively. One false negativity and one false positivity were also found. Abnormal radiologic features were not correlated with having a malignant palpable lesion. Evaluation of the palpable lesions by FNA and tissue biopsy together is effective for initial triage of the patients with suspect for a thoracic pathology. FNA alone is a convenient and easy method for this purpose especially when the material is immediately assessed for specimen adequacy. Diagn.

ABSTRACT: Fine-needle aspiration cytology guided by ultrasound imaging is a widely used diagnostic tool to evaluate neoplastic or inflammatory lesions of salivary glands. From February 2002 to February 2008 all the parotid lesions removed surgically in our Unit of Otolaryngology were reviewed. Study focused on sensitivity, specificity, accuracy, predictive values, likelihood ratios, and Kappa statistics for fine-needle aspiration cytology vs histological diagnosis in 176 cases. Fine-needle aspiration cytology sensitivity and specificity were 81% and 99%, respectively. Accuracy for malignancy was 97%, accuracy for benignity was 83%; positive and negative predictive values were 93% and 98%, respectively; likelihood ratio of positive and negative test results were 100.3 and 0.19, respectively ("positive" was used to define "malignant"). The prevalence of malignancy was 0.114. Kappa statistics for the degree of agreement between fine-needle aspiration cytology and histological results were 0.85 (95% CI = 0.71-0.99). Pre-operative fine-needle aspiration cytology diagnosis improves surgical treatment of parotid masses.Acta otorhinolaryngologica Italica: organo ufficiale della Società italiana di otorinolaringologia e chirurgia cervico-facciale 02/2011; 31(1):1-4. · 1.44 Impact Factor
