1.  Association of CTTN polymorphisms with the risk of colorectal cancer 
Purpose
Various studies searching for biomarkers to predict tumor metastasis or prognosis in both esophageal squamous cell carcinoma (ESCC) and head and neck squamous cell carcinoma (HNSCC) are currently underway. However, few data have been reported on its association with colorectal cancer (CRC). Single nucleotide polymorphisms (SNPs) are the most common known form of human genetic variation and may contribute to an increased susceptibility to cancer including CRC. The present study aimed to investigate whether the polymorphisms in the CTTN gene are associated with susceptibility to CRC in the Korean population.
Methods
A case-control study was performed to examine the relationship between the CTTN g.-9101C>T, g.-8748C>T, and g.72C>T polymorphisms and the risk of CRC. Polymerase chain reaction-restriction fragment length polymorphism analysis of g.-8748C>T, g.-9101C>T and Taqman analysis of g.72C>T were performed on blood samples from 218 patients with CRC and 533 control individuals. The g.-9101C>T, g.-8748C>T, and g.72C>T SNPs in CTTN and their haplotypes were analyzed.
Results
The genotype and allele frequencies of g.-9101C>T, g.-8748C>T, and g.72C>T did not differ between the patient group and the control group. Further, the haplotype of CTTN g.-9101C>T, g.-8748C>T, and g.72C>T did not differ between patient group and the control group. However, the genotype and allele frequencies of CTTN g.-9101C>T were significantly increased in the lymph node positive CRC group compared to the control group.
Conclusion
The CTTN g.-9101C>T polymorphism may influence lymph node positive CRC.

2.  Application of single incision laparoscopic surgery for appendectomy in children 
Purpose
Recently, single incision laparoscopic surgery (SILS) has been popular in use with its progress studied for more minimally invasive surgery and cosmetic improvement. We investigated the feasibility and efficacy of SILS for appendectomy (SILS-A) in children and compare it with conventional laparoscopic appendectomy (C-LA).
Methods
We studied, retrospectively, adolescent patients who underwent C-LA or SILS-A. There were 25 patients in the C-LA group and 30 patients in the SILS-A group. The clinical outcomes were compared between the groups.
Results
The SILS-A procedures were performed successfully in adolescent patients . There were no significant difference between the C-LA and SILS-A group with respect to demographic data and post-operative outcomes. There was one complication (4%) in the C-LA group and two complications (6.6%) in the SILS-A group, but there was no significant difference.
Conclusion
SILS-A was technically feasible and safe in children. Considering little postoperative scar and no difference in post-operative outcomes compared to C-LA, SILA could be applicable in adolescent patients. Larger studies and further technical implements will be necessary to assess the true benefit of this approach.

3.  Synchronous granular cell tumors in the perianus and chest wall 
Granular cell tumor (GCT) is a rare tumor that originates from the Schwann cells in the skin, soft tissues, and internal organs. Usually, GCTs are clinically benign, although malignant and multifocal forms are very rarely known to occur. Cases of GCT of the perianus are rare, and thus far, no study has reported synchronous GCTs of the perianus and the chest wall. We report a case of a 31-year-old woman with synchronous GCTs of the perianus and the chest wall to have a mind of consideration of the possibility of GCT in the differential diagnosis of perianal tumor.

4.  Primary adenosquamous carcinoma of the colon 
Journal of the Korean Surgical Society  2011;80(Suppl 1):S31-S35.
Adenosquamous cell carcinoma (Ad-SCC) of the colon is rare. The pathogenesis of Ad-SCC is unclear, however, several hypotheses have been suggested. The clinical presentation and gross findings of Ad-SCC of the colon are similar to those of adenocarcinoma of the colon, but Ad-SCC has a more aggressive clinical course and a poorer prognosis. We report on two cases of Ad-SCC of the colon with obstruction; a collision-type Ad-SCC that has not only obstruction but also numerous hepatic metastases, and a composite-type Ad-SCC treated with left hemicolectomy followed by an adjuvant chemotherapy.
