Thyroid Transcription Factor-1

Sažetak
Background & objectives: Thyroid Transcription Factor-1 (TTF-1) can be a useful marker for lung and thyroid primaries. However, TTF-1 expression has been reported in up to 2.5% of breast carcinomas. There are two main commercially available TTF-1 antibody clones: 8G7G3/1 and SPT24. Methods: A 60-year-old woman presented with a large tumour involving the entire right breast together with multiple pulmonary and mediastinal tumour masses. Due to the aggressive course, the working diagnosis was a lung primary producing breast metastasis. Breast and lung core needle biopsies both revealed a TTF-1, ER and GATA3 positive adenocarcinoma, while napsin A, PR and HER2 were negative. Results: Endocrine therapy was administered, leading to significant reduction in the size and number of pulmonary and mediastinal metastases. Two years later, a sanitary mastectomy was performed. The breast tumour was positive for ER and GATA3, and negative for napsin A and PR. This time, TTF-1 was performed with both commercially available clones, showing a positive reaction with SPT24 and a negative reaction using the 8G7G3/1 clone. Conclusion: Breast metastases from extramammary malignancies are rare (0.2-2% of all tumours), with lung being one of the most frequent primary sites. TTF-1 clone selection can have clinical significance in the workup of a potential metastatic lung adenocarcinoma, especially in settings with limited amount of tumour tissue. In the setting of breast vs lung primary, an antibody panel including napsin A and GATA3 should be used, as occasional ER- positive lung carcinomas as well as TTF-1 positive breast carcinomas have been documented.
