Feasibility Study of Ultrasonographic Criteria for Microscopic and Macroscopic Extra-Thyroidal Extension Based on Thyroid Capsular Continuity and Tumor Contour in Patients with Papillary Thyroid Carcinomas

Our purpose was to evaluate the feasibility of using ultrasonographic criteria of thyroid capsular continuity and tumor contour to differentiate macroscopic extra-thyroidal extension (ETE) from microscopic ETE, as well as non-ETE from ETE. On ultrasonography, we evaluated thyroid capsular continuity (C0 = continuous, C1 = discontinuous, C2 = invisible), and thyroid tumor contour (P0 = in normal parenchyma, P1 = abutting, P2 = bulging), which were grouped into type 1–9 classifications. Either C1–2 or P1–2 was more prevalent in ETE than non-ETE. C1 and P2 tended to be associated with macroscopic ETE, whereas C0 and P1 were significantly associated with microscopic ETE. Types 6, 8 and 9 were more likely to have ETE than non-ETE; type 6 (C1 P2) and type 9 (C2 P2) were significantly associated with macroscopic ETE, whereas type 8 (C2 P1) was associated more with microscopic ETE. Macroscopic and microscopic ETE, as well as non-ETE and ETE, can be differentiated using these pre-operative ultrasonographic criteria.     

Effect of Tongguan Capsules(通冠胶囊) on Restenosis after Coronary Stent Implantation:Study Protocol for A Randomized Controlled Trial

Background:Although percutaneous coronary intervention(PCI)had become widely employed therapeutic procedure for coronary artery disease,stent restenosis limited the benefits of this revascularization and the question how to prevent such events remained unresolved.While numerous empirical observations suggested Tongguan Capsules(通冠胶囊),a patented Chinese Medicine,could decrease frequency and duration of angina pectoris attacks,evidence supporting its efficacy on restenosis remained inadequate.Objective:This trial was designed to determine whether Tongguan Capsules would reduce restenosis rate in patients after successful stent implantation.Methods:Approximately 400 patients undergoing percutaneous coronary stent deployment were enrolled and randomized to control group or Tongguan Capsules(4.5 g/d)for 3 months.All patients received standard anti-platelet,anti-coagulation and lipid-decreasing treatments,concurrently.The primary clinical endpoint was the 12-month incidence of the major adverse cardiovascular events(defined as cardiac death,myocardial infarction,and recurrence of symptoms requiring additional revascularization).The angiographic end point was restenosis rate at 6 months.Conclusion:This study would provide important evidence for the use of Tongguan Capsules in patients after stent implantation in combination with routine therapies,which may significantly reduce incidence of the restenosis so as to potentially improve the clinical outcomes.(registration number:ChiCTR-TRC-ChiCTR-IIR-17011407)
