FINE NEEDLE ASPIRATION BIOPSY MEMPUNYAI PERANAN PENTING DAN AKURASI TINGGI SEBAGAI METODE DIAGNOSTIK PREOPERATIF TUMOR TULANG
ABSTRACT: Fine Needle
Aspiration Biopsy (FNAB) technique is gaining increasing popularity in the
diagnosis of musculoskeletal lesions because it offers some advantages such as
rapid , easy , with minimal complications, but its applicability in diagnosis
of bone tumors however has some limitations. This research was aimed to explore
the roles of FNAB and its accuracy as the preoperative diagnostic method
compared to histopathology examination from open biopsy or operation as a gold
standard. Research design was descriptive study and diagnostic test from cases
of bone tumors which were aspirated over a period of threeyears in Anatomic
Pathology Laboratory of Saiful Anwar Hospital Malang. The data was collected
with cross sectional method. Of the 106 patients who were subjected to FNAB, 22
cases were diagnosed as benign bone tumor,49 were primary malignant bone
tumor,24 were metastatic malignant bone tumor,1 cases was suspicious malignant
tumor, 5 cases were non neoplastic lesions, and 5 cases were inadequate/
inconclusive for diagnosis. Of the 16 cases which was analized with diagnostic
test, sensitivity of FNAB as preoperative diagnostic method was 100 %,
specificity was 90,91%, positive predictive value was 83,33 % and negative predictive
values was 100 % . Overall, diagnostic accuracy of FNAB was 93,75 %.It can be
concluded that FNAB has important roles to differentiate neoplasm or non
neoplasm lesion, benign or malignant tumor and primary or metastatic malignant
bone tumor. FNAB represented as a technique having high accuracy for preoperative
diagnostic method of bone tumor.
