Advances in diagnosis and treatment of thymic carcinoid / 基础医学与临床

ABSTRACT

Thymic carcinoid is a rare neoplasm with unclear risk factors and controversial classifications .Clinical manifestations vary from asymptomatic to many nonspecific symptoms , among which endocrinopathy seems to be as-sociated with poor prognosis .Image studies show no specificity both in CT and PET/CT, but are of great value in clinical staging .Ki67 index has been found to be a powerful tool for grading neuroendocrine tumors and further studies should be made .The diagnosis of thymic carcinoid mainly depends on pathology and immunohistochemistry plays a role in differential diagnosis .Radical resection is the first choice in treatment , and target therapy becomes possible with the development in molecular pathology .
