Review Meta Analysis
Systematic review and meta-analysis of totally laparoscopic versus laparoscopic assisted distal gastrectomy for gastric cancer.
Totally laparoscopic distal gastrectomy (TLDG) has been developed in the hope of improving surgical quality and overcoming the limitations of conventional laparoscopic assisted distal gastrectomy (LADG) for gastric cancer. The aim of this study was to determine the extent of evidence in support of these ideals. ⋯ TLDG may be a technically safe, feasible, and favorable approach in terms of better cosmesis, less blood loss, and faster recovery compared with LADG.

The aims of this study were to evaluate the associations between the maximum standardized uptake value (SUVmax) and prognostic factors in invasive lobular carcinoma (ILC) and to compare these results with those in invasive ductal carcinoma (IDC). ⋯ The SUVmax was significantly different according to the tumor grade, ER, EGFR, and Ki-67 for IDCs. The SUVmax exhibited a positive association with Ki-67 in ILC; however, it was not significantly different with other factors, which suggests that the role of (18)F-FDG PET/CT may be limited in ILC.

Case Reports
Ipsilateral partial anomalous pulmonary venous connection in right lung cancer with absent right upper lobe.
A partial anomalous pulmonary venous connection (PAPVC) is an uncommon congenital anomaly. This report documents the case of a 48-year-old man with PAPVC which was incidentally discovered with right lung cancer and absence of right upper lobe. ⋯ If the PAPVC is located in a different lobe, a pulmonary resection for lung cancer would precipitate an adverse outcome without a correction of the PAPVC. Surgeons should therefore be cautious regarding the potential existence of a PAPVC when a patient undergoes surgical procedures.

Meta Analysis Comparative Study
Radiofrequency ablation versus percutaneous ethanol injection for hepatocellular carcinoma: a meta-analysis of randomized controlled trials.
Radiofrequency ablation (RFA) and percutaneous ethanol injection (PEI) are treatment methods for patients with early-stage hepatocellular carcinoma (HCC) who are not suitable for surgery. Although some reports indicate that RFA is better than PEI, results from previous reviews and analyses are inconsistent. Therefore, this meta-analysis was performed to more thoroughly evaluate the effects of these treatments in patients with HCC. ⋯ RFA was only superior to PEI in Asian studies that included selection bias. Thus, there is insufficient evidence to support the idea that RFA is superior to PEI for patients with cirrhotic HCC. Additional large-scale, multicenter, randomized controlled trials that control for selection bias are needed to fully elucidate the optimal treatment method for HCC.

Hepatic metastasectomy for patients with primary colorectal cancer offers better long-term outcome, and chemotherapy can increase the rate of hepatic resectability for patients with initially inoperable disease. The pattern of liver metastasis and status of the primary tumor are rarely discussed in the analysis of long-term outcome. In this report, we evaluate the influence of the pattern of metastasis on clinical features and prognosis. ⋯ In colorectal cancer, centrally located liver metastasis represents a poor prognostic factor after hepatectomy, and is associated with early recurrence. Neoadjuvant chemotherapy may be used to downstage centrally located liver metastases to improve outcome.
