Small cell anaplastic carcinoma (SCAC) is usually treated non-surgically and, therefore, diagnosis is best done by the least invasive means. Percutaneous fine-needle aspiration biopsy is very accurate in diagnosing malignancy and reasonably accurate in diagnosing malignant cell type. An unequivocal cytological diagnosis of SCAC has a positive predictive value of 0.90 at our institution. The accuracy is lowered by uncertain or suggestive cytological diagnoses.
小细胞间变性癌（SCAC）通常采用非手术治疗，因此，最好通过侵入性最小的方法进行诊断。经皮细针穿刺活检在诊断恶性肿瘤方面非常准确，在诊断恶性细胞类型方面也较为准确。在我们机构，SCAC明确的细胞学诊断阳性预测值为0.90。不确定或提示性的细胞学诊断会降低准确性。
