BACKGROUND:The effects of the BRAF V600E mutation on prognostic factors and poor clinical outcomes in papillary thyroid cancer (PTC) have not been fully quantified. The authors performed comprehensive meta-analysis to assess the strength of associations between these conditions and the BRAF V600E mutation. METHODS: The authors identified the clinical studies that examined the association of the BRAF V600E mutation in surgical specimens with clinicopathologic outcomes between January 2003 and October 2010 using the Medline database. One hundred thirty-one relevant studies were hand-searched. The authors selected 27 studies that included 5655 PTC patients. They calculated the pooled odds ratios (ORs) or risk ratios with 95% confidence intervals (CIs) for each study using a random effect model. RESULTS: The average prevalence rate of the BRAF V600E mutation was 49.4%. In 26 studies, compared with the patients who had the wild-type BRAF genes, the PTC patients with the BRAF V600E mutation had increasedORs of an extrathyroidal invasion (OR, 2.14; 95% CI, 1.68-2.73), a lymph node metastasis (OR, 1.54; 95% CI, 1.21-1.97), and an advanced TNM stage (OR, 2.00; 95% CI, 1.61-2.49). In 8 studies, patients with the mutation had 2.14-fold increased risk of recurrent and persistent disease (95% CI, 1.67-2.74). The associations were generally consistent across the different study populations. CONCLUSIONS: This meta-analysis demonstrates that the BRAF V600E mutation is closely related to the high-risk clinicopathological factors and poorer outcome of PTC. The results obtained here suggest that the BRAF V600E mutation should be considered as a poor prognostic marker in PTC and may lead to better management for individual patients.

The BABA technique for endoscopic thyroid surgery is a feasible method of total thyroidectomy with a low rate of postoperative complications and, additionally, excellent cosmetic results. Therefore, in selected cases of thyroid cancer, the BABA endoscopic total thyroidectomy should be considered as a valid surgical option.

Robotic endoscopic thyroidectomy using the BABA technique is a feasible procedure and can be performed safely. It provides an excellent operative field view enabling easy identification of vital structures. It also gives the desired cosmetic results and minimal postoperative pain similar to conventional endoscopic thyroid surgery using the BABA technique.

Background: The incidence of breast cancer in young women (age < 35) is low. The biology of the disease in this age group is poorly understood, and there are conflicting data regarding the prognosis for these women compared to older patients.

The bilateral axillo-breast (BAB) approach for endoscopic thyroidectomy shows insignificant postoperative complications, except transient vocal cord palsy, as well as good cosmetic results. It is also a feasible method for total thyroidectomy. Therefore, the BAB approach for endoscopic total thyroidectomy can be the surgical treatment of choice for selected cases of thyroid cancer.

The BRAF(V600E) mutation was associated with high-risk clinicopathologic characteristics in patients with PTC. The BRAF(V600E) mutation may be a potential prognostic factor in PTC patients.

The incidence of thyroid cancer has rapidly increased, with a decrease in tumors of large size, LN involvement, and ETE, although the decreasing rates of LN involvement and ETE were not as prominent as decreasing rates of large size tumors. The mortality and recurrence rates have also decreased. Future long-term follow-up of patients diagnosed in the most recent decade is needed to confirm the prognostic characteristics of Korean PTC patients.

RFA may be an effective and safe alternative to repeat surgery in patients with locally recurrent small thyroid cancers.
