Abstract

Thyroid transcription factor 1 (TTF-1) is considered a highly sensitive and specific marker for primary lung adenocarcinoma. However, in recent years retrospective studies of tumor samples have confirmed that, although rare, TTF-1 can also be expressed in colorectal adenocarcinoma. There are a few case reports of patients with TTF-1-positive colon adenocarcinoma in the medical literature but none of TTF-1-positive rectal adenocarcinoma. Here, we present a case of rectal adenocarcinoma with lung metastasis found to be TTF-1 positive on immunohistochemistry. A review and discussion of the available literature is also included.

摘要

甲状腺转录因子1(TTF-1)被认为是原发性肺腺癌的一种高度敏感和特异的标志物。然而,近年来对肿瘤样本的回顾性研究证实,虽然罕见,但TTF-1也可在结直肠癌中表达。医学文献中有几例TTF-1阳性结肠腺癌患者的病例报告,但没有TTF-1阳性直肠腺癌的报告。在此,我们报告一例直肠腺癌伴肺转移患者,免疫组化显示TTF-1阳性。本文还包括对现有文献的综述和讨论。
