Research progress on multimodality treatment for primary tracheal adenoid cystic carcinoma / 中华放射肿瘤学杂志

Primary tracheal adenoid cystic carcinoma (TACC) is exceedingly rare. Surgical resection is the main treatment for TACC. Whether the operation is radical or not is a key prognostic factor. Postoperative radiotherapy may be suitable to improve the local control rate and long-term survival for patients with positive surgical margin. For unresectable, recurrent and metastatic TACC patients, definitive radiotherapy, chemotherapy and molecular targeted therapies have yielded certain clinical efficacy. The aim of this review is to summarize the research progress on multimodality treatment for TACC.

Application of core needle biopsy guided by ultrasound in diagnosis of thyroid nodule / 中华内分泌外科杂志

Objective To explore the role of ultrasound-guided core needle biopsy in diagnosis and treatment of thyroid nodules.Methods 778 cases undergoing ultrasound-guided core needle biopsy in our department from Jan.2012 to Dec.2014 were retrospectively analyzed,and the sensitivity,specificity and accuracy were calculated.Results All the patients were operated successfully.Except for 21 nodules undiagnosed,16.4％ (124/757) were histologically diagnosed as malignant and 83.6％ (633/757) were benign.15 samples of the 124 malignant nodules were less than 10 millimeter in diameter.The sensitivity,specificity and accuracy were 100％,94.8％ and 95.6％,respectively.Of the ultrasound features,blood flow,boundary,internal situation and calcification were statistically significant between benign and malignant nodules,but not so between the groups of different greatest dimentions.Conclusion Ultrasound-guided core needle biopsy is safe and effective for obtaining thyroid nodule tissue,and it is helpful for diagnosis of thyroid diseases.
