Background: Anaplastic thyroid cancer (ATC) is the most aggressive thyroid malignancy and has an extremely poor prognosis, necessitating novel therapeutic strategies. This study investigated the role of anillin (ANLN) in ATC, focusing on its impact on tumor growth and metastasis through the RhoA/PI3K/AKT signaling pathway.
Methods: TCGA and GEO datasets were analyzed to identify key molecular alterations in thyroid cancer.
Background: Our objective was to assess the viability and oncological security of a gasless, transaxillary single-incision endoscopic procedure for performing total thyroidectomy and bilateral central neck dissection (TT + BCND). This study focused on patients diagnosed with bilateral papillary thyroid microcarcinoma (PTMC).
Method: Between April 2020 and November 2021, 22 patients with bilateral PTMC underwent single-incision, gasless, transaxillary endoscopic TT + BCND.
Background: In a previous study, we proposed a novel anatomy-based five-settlement method for transaxillary endoscopic thyroidectomy (fs-TAT) for patients with papillary thyroid carcinoma. The safety of this new method has been reported in a retrospective study of a single cohort. The safety and short-term oncological outcome of this method was confirmed by comparing it with conventional open surgery (COT) in patients with papillary thyroid microcarcinoma.

Based on our concept of mesothyroid excision in open surgery, we proposed a novel anatomy-based five-settlement method in ET the GUA approach. This preliminary report aimed to explore the efficacy and safety of this method in patients with papillary thyroid carcinoma (PTC).

Methods: This retrospective cohort study enrolled patients with PTC who underwent revision LND between 1 January 2012, and 31 December 2021. The initial and revised clinical data were retrieved.
Background: To evaluate the relationship between lymph node yield (LNY) from the initial central neck dissection (CND) and the risk of recurrence in patients undergoing reoperative CND for papillary thyroid cancer (PTC).
Method: We reviewed clinical data from all patients with pathologically proven PTC who underwent central neck and/or lateral neck dissection reoperations at Nanfang Hospital between 2012 and 2020. Patient demographics, tumor characteristics, clinical data and follow-up information were obtained.
In our previous study, we have shown that CRLF1 can promote proliferation and metastasis of papillary thyroid carcinoma (PTC); however, the mechanism is unclear. Herein, we investigated whether the interaction of CRLF1 and MYH9 regulates proliferation and metastasis of PTC cells via the ERK/ETV4 axis. Immunohistochemistry (IHC), qPCR, and Western blotting assays were performed on PTC cells and normal thyroid cells to profile specific target genes.

We report a case of a 42-year-old woman with occasionally found mass in the right anterior area of the neck. After a total thyroidectomy, histopathology and immunohistochemistry tests confirmed primary squamous cell carcinoma of the thyroid with the exclusion of all other possible primary tumor locations.

Method: One hundred and forty patients with pN + PTC who underwent neck dissection were enrolled into this study. SSLN was resected and used as a specimen to investigate the relationship of SSLN with several clinicopathological parameters.
Background: Tyrosine kinase inhibitors (TKIs) have been administered to advanced or radio-iodine refractory differentiated thyroid carcinoma (RR-DTC) patients for years. We performed a pooled analysis to explore the frequency of severe adverse effects in advanced or RR-DTC patients treated with sorafenib and lenvatinib.
Methods: We performed a comprehensive search of computerized databases, including PubMed, Web of Science, Ovid, EMASE, and the Cochrane Library, from the drugs' inception to July 2018 to identify clinical trials.
Purpose: Currently the extent of lymph node dissection (LND) for papillary thyroid microcarcinoma (PTMC) remains controversial. The present study aims to investigate the clinicopathologic predictors of lymph node metastasis (LNM) and prognosis in PTMC patients from Guangdong to enable appropriate treatment and follow-up.
Methods: Data including demographics, tumor size, multifocality, extrathyroidal extension (ETE) and concomitant thyroiditis were collected from 374 untreated PTMC patients from Guangdong, China.
Accumulating evidence has indicated that aberrantly expressed microRNAs (miRs) are extensively involved in cancer development and progression. MiR-639 has been reported to act as tumor promoter in various types of cancer. However, the biological function and underlying molecular mechanism of miR-639 in thyroid carcinoma (TC) have not been intensively investigated.

Aim: To investigate the regulative effect of miRNA (miR)-221 on colorectal carcinoma (CRC) cell radiosensitivity and the underlying mechanisms.
Methods: A human CRC-derived cell line was cultured conventionally and exposed to different doses of X-rays (0, 2, 4, 6 and 8 Gy). The total RNA and protein of the cells were extracted 24 h after irradiation, and the alteration of miR-221 and phosphatase and tensin homolog deleted on chromosome 10 (PTEN) gene mRNA expression was detected by real-time reverse transcriptase polymerase chain reaction (PCR).
