Predictive factors of central lymph node metastasis in papillary thyroid carcinoma.

Purpose: The aim of this study was to evaluate the correlation between central lymph node (CLN) metastasis and clinicopathologic characteristics of papillary thyroid cancer (PTC). In addition, we investigated the incidence and risk factors for contralateral CLN metastasis in unilateral PTC. This study suggests the appropriate surgical extent for CLN dissection.

Short-term outcomes after laparoscopic surgery following preoperative chemoradiotherapy for rectal cancer.

Purpose: The safety and the feasibility of performing laparoscopic surgery for rectal cancer after preoperative chemoradiotherapy (CRT) have not yet been established. Thus, the aim of this study was to evaluate the efficacy and the safety of laparoscopic rectal cancer surgery performed after preoperative CRT.

Methods: We enrolled 124 consecutive patients who underwent laparoscopic surgery for rectal cancer.
