中文摘要：

小细胞肺癌是肺常见的神经内分泌肿瘤,其恶性程度高、生长速度快、易早期转移、预后差。对小细胞肺癌进行准确的分期,可制定个性化的治疗方案,从而改善患者的预后。PET/CT一次检查可获得全身代谢和解剖图像,提高了诊断的准确性和整体性。目前PET/CT已在临床得到广泛应用,并在小细胞肺癌的诊断、分期、指导治疗及预后评估中发挥着重要作用。本文对PET/CT在小细胞肺癌分期与治疗中的价值进行综述。

英文摘要：

Small cell lung cancer is the most common primary neuroendocrine malignancy of the lung and is characterized by high malignant degree,rapid doubling time,easy metastasis in early stage and poor prognosis.Accurate staging of small cell lung cancer can formulate personalized therapeutic plans and improve the prognosis of patients.PET/CT can obtain metabolism and anatomical images of the whole body in one scan and improve the diagnostic accuracy and integrity.PET/CT has been widely applied to clinical practice now.PET/CT will play a more and more important role in diagnosis,staging,treatment and prognosis assessment of patients with small cell lung cancer.The value of PET/CT in staging and treatment of small cell lung cancer was reviewed in this article.
