The study aims to show that fine needle aspiration biopsy (FNAB) can be as good as, or better than the known and accepted standard procedures in terms of being less costly, less traumatic, simpler and can be done on an outpatient basis with minimum expertise on the part of the clinician. A total of 165 outpatients and inpatients (14 years above) with solid soft tissue tumors except those with previous biopsy were used in the study. All patients were subjected to both fine needle aspiration as well as excision biopsy. Aspiration smear were examined, compared and analyzed. Results showed that FNAB is comparable with the routine biopsy techniques with a sensitivity of 92.85%, specificity of 99.21% and overall accuracy of 98.06%. Analysis revealed that there was no significant difference between the surgical and non-surgical residents. The procedure is safe with no morbidity nor mortality encountered in the series.
To find out the sensitivity and specificity of FNAB and compare these with those of the routine biopsy technique, i.e., incision or through-cut biopsy (2) To find out if other resident physicians with no training in surgery to perform the FNAB can get significant results (3) To find out if FNAB is a safe procedure
