简要总结
Tumor deposits (TD), nodules in the peritumoral adipose tissue with no architectural residue of lymph node, which is a definition often being confusing to the extranodal extension (ENE), have been described in several malignancies and linked to a worse prognosis. In gastric cancer and colon cancer, TD and ENE should be distinguished and collected separately in 8th AJCC manual. However, in thyroid cancer, TD as a collection variable was absence in both the 8th AJCC manual and the 2015 ATA guideline. This is a study that revealed the presence of TD by reviewing a large number of papillary thyroid carcinoma (PTC) specimens and explored its prognostic value by constructing a nomogram to accurately predict disease-free survival in PTC patients.

结局指标
主要结局
disease-free survival (DFS) after diagnosis
时间窗: between 2015 and 2021
The primary outcome was disease-free survival (DFS) after diagnosis, with endpoints as tumor locoregional recurrence, distant metastasis, and disease-specific death. If a patient was deceased, the cause of death was confirmed by the death certificate or the hospitalization record to identify disease-specific death.
次要结局
- Disease recurrence(between 2015 and 2021)
