This randomized phase III trial compared hepatic arterial infusion (HAI) chemotherapy with 5-fluorouracil (5-FU) followed by uracil/tegafur (UFT) and leucovorin (LV) versus UFT/LV alone for patients with curatively resected liver metastases from colorectal cancer (CRC). ⋯ Although this study was limited by a small sample size after early study termination, our analysis found that HAI with 5-FU followed by UFT/LV did not improve the DFS of patients with curatively resected liver metastases from CRC compared with UFT/LV alone. The future studies are necessary to evaluate the survival benefit of HAI in combination with newer systemic chemotherapeutic agents for patients with resectable liver metastases from CRC.

Proper preoperative staging is vital in the treatment of breast cancer patients. Fluorine-18-labeled 2-fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography (18F-FDG-PET/CT) and conventional diagnostic modalities including ultrasonography (US), mammography (MG), and magnetic resonance imaging (MRI) play a greater role. ⋯ US and MRI should remain the first line for the diagnosis of breast cancer. Both MRI and FDG-PET/CT could accurately diagnose the primary breast cancer and stage the axilla lymph nodes, but further large population study is needed.

Oxaliplatin-induced neurotoxicity is the single main dose-limiting factor in the treatment of colorectal cancer. The degree of neurotoxicity may be either acute and reversible or observed as cumulative and chronic peripheral nerve damage leading to peripheral neuropathy (PNP), walking difficulties, extremity hypersensitivity, tingling and numbness, and increased pain sensation. ⋯ Our study lays ground for further larger scale longitudinal studies on oxaliplatin neurotoxicity and its prevention. We believe that early diagnosis of oxaliplatin-induced neurotoxicity is essential in the prevention of irreversible nerve damage and should be prioritized when assessing and evaluating treatment so that adequate adjustment may be made.

The association between cyclooxygenase-2 (COX-2) gene polymorphisms and hepatocellular carcinoma (HCC) has been widely reported, but the results are still controversial. To clarify the effect of COX-2 -1195G/A (rs689466), -765G/C (rs20417), and +8473T/C (rs5275) polymorphisms on HCC risk, a meta-analysis was performed. ⋯ Our meta-analysis suggests that -1195G/A, -765G/C, and +8473T/C in COX-2 may contribute significantly to HCC risk.

Sevoflurane anesthesia is a high-risk factor for postoperative cognitive dysfunction (POCD) in elderly patients. Recently, some studies demonstrated that dexmedetomidine (DEX) could reduce the incidence of POCD caused by sevoflurane anesthesia. We hypothesized that DEX could reduce the incidence of POCD caused by sevoflurane anesthesia through decreasing plasma interleukin (IL-6) and tumor necrosis factor (TNF)-α concentrations. ⋯ The POCD incidence was higher in elderly patients receiving sevoflurane anesthesia and DEX could alleviate POCD in these patients through decreasing plasma TNF-α and IL-6 concentrations.
