  • Title: Fine-needle aspiration biopsy of pancreatic masses.
    Author: Athlin L, Blind PJ, Angström T.
    Journal: Acta Chir Scand; 1990 Jan; 156(1):91-4. PubMed ID: 2181799.
    Abstract:
    The results of fine-needle aspiration biopsy of pancreatic masses in 79 patients (percutaneous with ultrasonic guidance in 23 and peroperative in 56) were evaluated and correlated to survival (follow-up at least 2 years). The original biopsy diagnosis was malignancy in 41 patients, histologically confirmed in 19, all but two of whom died of cancer within 18 months. None of the 22 patients without histologic verification of the primary malignant cytodiagnosis survived for 18 months. The fine-needle biopsy showed benign cells in 30 patients, in 13 of whom histologic diagnosis was obtained, revealing carcinoma in seven. Six of these seven died within a year, but of the six with histologically benign lesion, five survived for more than 2 years. All 17 patients without histologic verification of benign aspiration biopsy findings survived more than 24 months. The biopsy diagnosis was inconclusive in eight patients. Four of them proved to have carcinoma and died within 18 months. The sensitivity of fine-needle aspiration biopsy of the pancreas was 76% in this study and the predictive value for malignancy was 100%.
