To measure the frequency and analyze the rationale and potential diagnostic benefits of converting the fine needle aspiration (FNA) procedure to core biopsy.
The frequency of conversion to core biopsy was calculated over 13 months. Analysis of these cases was conducted in regard to the appropriateness for conversion and whether the core biopsy provided additional specific diagnostic information.
During this period, the onsite triaging pathologist recommended FNA conversion to core biopsy in 31 of 821 procedures (3.7%). In 3 instances, the core biopsy could not be performed. The rationale for conversion in the remaining 28 cases (3.4%) included either scant aspirated material in 9 cases (32%) or an anticipated need for additional histologic material to further characterize the lesion in the other 19 (68%). In 27 cases (96%), the rationale for conversion was considered to be appropriate, and in 3 of these (11%) the core provided a change in diagnosis. Additional useful diagnostic information was identified in 12 cases (44%).
Conversion to core biopsy during FNA is infrequent but justified in most cases. Appropriate utilization of this approach is helpful and may be cost effective.
测量将细针穿刺抽吸（FNA）程序转换为粗针活检的频率，并分析其原理及潜在的诊断益处。
计算13个月内转换为粗针活检的频率。针对这些病例进行分析，判断转换的合理性以及粗针活检是否提供了额外的特异性诊断信息。
在此期间，现场分诊病理学家在821例手术中的31例（3.7%）建议将FNA转换为粗针活检。有3例无法进行粗针活检。其余28例（3.4%）转换的原因包括9例（32%）吸取的材料不足，或其他19例（68%）预计需要额外的组织学材料来进一步明确病变特征。在27例（96%）中，转换的理由被认为是合理的，其中3例（11%）粗针活检改变了诊断结果。在12例（44%）中发现了额外有用的诊断信息。
FNA期间转换为粗针活检的情况并不常见，但在大多数情况下是合理的。合理使用这种方法是有帮助的，而且可能具有成本效益。
