Colorectal cancer is the third most common cancer in Korea and the third leading cause of death from cancer. Treatment outcomes for colon cancer are steadily improving due to national health screening programs with advances in diagnostic methods, surgical techniques, and therapeutic agents.. The Korea Colon Cancer Multidisciplinary (KCCM) Committee intends to provide professionals who treat colon cancer with the most up-to-date, evidence-based practice guidelines to improve outcomes and help them make decisions that reflect their patients’ values and preferences. These guidelines have been established by consensus reached by the KCCM Guideline Committee based on a systematic literature review and evidence synthesis and by considering the national health insurance system in real clinical practice settings. Each recommendation is presented with a recommendation strength and level of evidence based on the consensus of the committee.

We discuss the technical details and operative advantages of approaching pathologies from the contralateral side in cases of asymmetric spinal stenosis. The contralateral approach offers better manipulative freedom and a more accessible target approach along the plane of the pathology, allowing safer decompression and facet preservation; further, this approach is ergonomic for surgeons. We recommend the adoption of this approach in decompressing asymmetric spinal stenosis.

Cordyceps bassiana has long been used as an oriental medicine and reported to possess diverse biological activities. The fruiting bodies of Cordyceps bassiana was extracted with ethanol and then further fractionated with n-hexane, ethyl acetate, n-butanol and water. The butanol fraction from Cordyceps bassiana (CBBF) exhibited the most effective in anti-inflammatory activity in RAW 264.7 macrophages and the roles of CBBF on the anti-inflammation cascade in LPS-stimulated RAW 264.7 cells were studied. To investigate the mechanism by which CBBF inhibits NO, iNOS and COX-2, the activation of IκB and MAPKs in LPS-activated macrophage were examined. Our present results demonstrated that CBBF inhibits NO production and iNOS expression in LPS-stimulated RAW 264.7 macrophage cells, and these effects were mediated through the inhibition of IκB-α, JNK and p38 phosphorylation. Also, CBBF suppressed activation of MAPKs including p38 and SAPK/JNK. Furthermore, CBBF significantly suppressed LPS-induced intracellular ROS generation. Its inhibition on iNOS expression, together with its antioxidant activity, may support its anti-inflammatory activity. Thus Cordyceps bassiana can be used as a useful medicinal food or drug for further studies.

A nodular density was detected on a chest radiograph taken from a 57-year-old Korean woman who was visiting a hospital for a routine check. Chest computed tomography revealed a 4.8 cm lobulated mass in the right lung and another focal nodular lesion in the left lung; biopsies of both lungs revealed adenocarcinoma. We conducted DNA sequencing and peptide nucleic acid clamping to investigate the potential double primary lung cancer. The results verified that the mass in the right lung had a mutation in the epidermal growth factor receptor, whereas the nodule in the left lung had a wild-type sequence, showing that these two were genetically different cancers from one another. Thus, we demonstrate that genetic testing is useful in determining double primary lung cancer, and we herein report on this case.

PURPOSE: There is no consensus regarding the difference in outcomes of HCV in patients who receive living donor liver transplantation (LDLT) or compared to deceased donor liver transplantation (DDLT). The aims of this study were to compare characteristics between LDLT and DDLT groups and to identify risk factors affecting patient survival. METHODS: We retrospectively reviewed the multicenter records of 192 HCV RNA-positive patients who underwent liver transplantation. RESULTS: Thirty-five patients underwent DDLT, and 146 underwent LDLT. The 1-, 3-, and 5-year patient survival rates were 66.7%, 63.0%, and 63.0% in the DDLT group and 86.1%, 82.3%, and 79.5% in the LDLT group (P = 0.024), respectively. After propensity matching, the patient survival curve of the LDLT group was higher than that of the DDLT group. However, there was no statistically significant difference in patient survival between the 2 groups (P = 0.061). Recipient age ≥ 60 years, LDLT, and use of tacrolimus were positively associated with patient survival in multivariate analyses. CONCLUSION: LDLT appears to be suitable for HCV-infected patients if appropriate living donor is available.
