Management of gastrointestinal stromal tumors (GISTs) has been transformed with tyrosine kinase inhibitors (TKIs). While data on optimal duration of adjuvant imatinib remains elusive, guidelines for administration of neoadjuvant TKIs remain unknown. ⋯ Neoadjuvant TKIs can be effectively used for the treatment of primary and recurrent/metastatic GIST. While duration of neoadjuvant therapy, KIT mutation status, and the need for multivisceral resection can help to predict higher risk for recurrence, progression on neoadjuvant TKIs can aid in selection of patients with recurrent/metastatic disease for surgical resection.

Comparative Study
Atypia of undetermined significance in thyroid fine-needle aspiration cytology: prediction of malignancy by US and comparison of methods for further management.
Further management for thyroid nodules with cytological atypia of undetermined significance (AUS) has made controversial conclusions. The aim of this study was to evaluate the most reliable ultrasonography (US) findings to predict malignancy in thyroid nodules with AUS, and to compare inconclusive rates of repeat fine-needle aspiration (rFNA) and core needle biopsy (CNB) in nodules with AUS. ⋯ Nodule echogenicity and US diagnosis can be predictive factors of malignancies for the thyroid nodules with cytological AUS. The CNB is more useful than rFNA for reducing the frequency of inconclusive results after initial AUS.

Randomized Controlled Trial Comparative Study
Comparison of two preoperative inspiratory muscle training programs to prevent pulmonary complications in patients undergoing esophagectomy: a randomized controlled pilot study.
Postoperative pulmonary complications (PPCs) are the most commonly reported complications after esophagectomy. The aim of this study was to examine the effect and feasibility of preoperative inspiratory muscle training-high intensity (IMT-HI), and IMT-endurance (IMT-E) on the incidence of PPCs in patients following esophagectomy for esophageal cancer (EC). ⋯ Preoperative IMT-HI showed to be a promising, effective, and feasible intervention to reduce PPCs in EC patients undergoing esophagectomy. Further research with a larger sample size is recommended.

For years, the outcome of colorectal cancer (CRC) surgery has been inferior in Denmark compared to its neighbouring countries. Several strategies have been initiated in Denmark to improve CRC prognosis. We studied whether there has been any effect on postoperative mortality based on the information from a national database. ⋯ The 30-day mortality rate after elective major surgery for CRC has decreased significantly in Denmark in the past decade. Laparoscopic surgical approach was associated with a reduction in mortality in colon cancer.

Liver transplantation (LT) is performed in selected patients with neuroendocrine hepatic metastases. Survival benefit and the risk of tumor recurrence after LT, also exacerbated by immunosuppressive therapy, remain important clinical issues. Whether patients with particular types of neuroendocrine tumors (NET) benefit more than others is unclear. ⋯ LT might be considered in carefully selected patients. The risk of tumor recurrence remains a significant clinical problem after LT, but data focused on immunosuppression issue are lacking, and there are no currently approved strategies for prevention of recurrence or follow-up protocols. Further studies are needed to define universally accepted inclusion criteria, reliable predictors of better outcome, and optimal timing for LT.
