Seventeen patients underwent a thyroid nodule FNAB (results: 12 benign, one follicular neoplasm, three suspicious for malignancy, and one papillary thyroid cancer [PTC]), from which six underwent thyroidectomy; PTC was confirmed by surgical pathology for all cases (8.5% of all nodules observed).
In this report a further case of SV-PTC is described which was associated to Hashimoto's thyroiditis, a finding never described in the cytological literature up to now for SV-PTC; this association created further differential diagnostic problems.The neoplasm displayed RET-PTC1 fusion.
We describe a case of papillary thyroid carcinoma with fibromatosis/fasciitis-like stroma (PTC-FLS) that contained the rare BRAF c.1799_1801delTGA (p.V600_K601delinsE) mutation, which has not previously been reported in this tumour, as well as the CTNNB1 c.133T>C (p.S45P) mutation.
To find an appropriate management strategy for patients with T1bN0M0 PTC, the outcomes of active surveillance for T1bN0M0 to T1aN0M0PTC were investigated and compared, and the outcomes of surgery for T1bN0M0 PTC were studied.
The aim of this study was to evaluate the clinicopathologic characteristics of the MFV-PTC treated in the Yonsei University College of Medicine.Between September 2007 and July 2012, 18,697 patients with PTC were treated in our institution.
BACKGROUND The aim of this study was to investigate the expression of the BRAF V600E gene mutation and the RET/PTC gene rearrangement in the progression of papillary thyroid carcinoma (PTC) in 50 patients from Inner Mongolia.
Comparing the cytological or, when performed, histological diagnoses with the results of FNAB-Tg, we found that in 24 cases of lymph node metastases from PTC (19 lymph nodes from patients at the first diagnoses and 5 lymph nodes from PTC patients in follow up) the mean level of Thyroglobulin was 1840.11 ng/ml; range: <0,2 to 11440 ng/ml.
Discovering the mechanism of PTC genesis and progression and finding new potential diagnostic biomarkers/therapeutic target genes of PTC are of great significance.
These results highlight an important role of <i>miR-195</i> in the initiation and progression of PTC and implicate the potential application of <i>miR-195</i> in PTC target therapy.
Microscopic examination of CMV-PTC revealed predominately cribriform and morular pattern of cancer cells with characteristic nuclear features of papillary thyroid carcinoma.Psammoma body is rare.
Radiation exposure, young age, and female gender are associated with high prevalence of RET/PTC1 and RET/PTC3 in papillary thyroid cancer: a meta-analysis.
Similarly, DIO3 mRNA levels were higher in PTC samples harboring the BRAF(V600E) mutation as compared with those with RET/PTC1 rearrangement or negative for these mutations (P<0.001).
Six of 27 PTCs (22%) had ret proto-oncogene (RET) fusions (RET/PTC1, n = 5; RET/PTC3, n = 1); 2 tumors measured >2 cm and diffusely involved the thyroid, and 5 had lymphatic invasion, with vascular invasion in 2.
The aims of the current study were to explore plasma lncRNAs as a novel biomarker panel for the diagnosis of non-131I-avid lung metastases of PTC and to investigate the plasma lncRNA expression levels associated with survival in PTC patients with lung metastases.
