REVIEW
Sagit Stern, Elad Dagan, Eran E Alon, Ziv Gil, Gideon Bachar
The incidence of papillary thyroid carcinoma has been on the rise in the past few decades while the disease specific mortality remains stable. During prophylactic central neck dissection (level 6), an average of 60% positive occult lymph nodes metastasis are found, hence the justification for performing a prophylactic central neck dissection. The opponents for performing neck dissection claim that the disease specific mortality is low regardless of the operation and that adding a neck dissection will, significantly, increase surgical morbidity...

Wei-Ping Jiao, Lei Zhang
BACKGROUND: Previous studies have demonstrated that ultrasonography is the recommended imaging modality for preoperative staging of papillary thyroid carcinomas (PTCs). However, only a few studies have kept watch on preoperative evaluation of capsular invasion (CI) or extracapsular extension (ECE) and cervical lymph node metastasis using preoperative ultrasonography. This study aimed to investigate the relationship between the CI or ECE and the cervical lymph node metastasis in PTCs using preoperative ultrasonography and postoperative pathology in Chinese patients...

Cellular senescence has been perceived as a barrier against carcinogenesis. However, the senescence-associated secretory phenotype (SASP) of senescent cells can promote tumorigenesis. Here, we show senescent tumour cells are frequently present in the front region of collective invasion of papillary thyroid carcinoma (PTC), as well as lymphatic channels and metastatic foci of lymph nodes. In in vitro invasion analysis, senescent tumour cells exhibit high invasion ability as compared with non-senescent tumour cells through SASP expression...

BACKGROUND: More than 90% of all thyroid cancers are differentiated thyroid carcinomas (DTC) with a 10 year survival rate greater than 90%. The commonly used risk stratification systems for DTC include: European Organization for Research and Treatment of Cancer (EORTC), AGES (Age, histologic Grade, Extent of tumor, Size), AMES (Metastasis) and MACIS (Completeness of resection, local Invasion). Other systems are also utilized. Several new factors that may be involved in DTC risk stratification have emerged in recent studies, with other "traditional" factors being challenged...
