Although about 50% of lung cancers have distant metastasis at the time of initial diagnosis, colonic metastases are extremely rare. This report presents a rare clinical case of colonic metastasis from primary squamous cell carcinoma of the lung. A 60-year-old female with anorexia and fatigue was referred to the department of pulmonary surgery in our(More)
We herein report a neuropathological and immunohistochemical analysis of a brain from a 25-year-old male with idiopathic type of Lennox-Gastaut syndrome (LGS). The clinical pictures, such as seizure type and progressive mental deterioration with an initial normal psychomotor and mental development in a man were typical of LGS. A routine neuropathological(More)
Malignant peripheral nerve sheath tumors (MPNSTs) are rare soft tissue tumors that arise from a peripheral nerve or exhibit nerve sheath differentiation. Most of these tumors arise on the trunk, extremities, or head and neck regions; they are very rarely located in the abdominal cavity. The patient was a 71-year-old man who was referred to our hospital for(More)
BACKGROUND Single-port laparoscopic surgery is a new technique that leaves no visible scar. This new technique has generated strong interest among surgeons worldwide. However, single-port laparoscopic colon surgery has not yet been standardized. Our aim in this study was to evaluate the feasibility of single-port laparoscopic colectomy compared with(More)
The gastrointestinal tract is continuously exposed to a variety of chemicals and commensal bacteria. Recent studies have shown that changes in gut microbial populations caused by chlorine or other chemicals in the drinking water influence the development of human colorectal cancer, although the mechanism of tumorigenesis in the gut epithelium is obfuscated(More)
BACKGROUND In stage IV colorectal cancer (CRC) with unresectable metastases, whether or not resection of the primary tumor should be indicated remains controversial. We aim to determine the impact of primary tumor resection on the survival of stage IV CRC patients with unresectable metastases. METHODS We retrospectively investigated 103 CRC patients with(More)
The standard operation for colitic cancer in ulcerative colitis (UC) is restorative proctocolectomy; however, sporadic colorectal cancer (CRC) can coincidentally arise in patients with UC and the optimal procedure remains controversial. Therefore, it is crucial to preoperatively determine whether the CRC in UC is a sporadic or colitic cancer. We report a(More)
INTRODUCTION Morgagni's or Larrey's diaphragmatic hernias are relatively uncommon. If the defect is too large for primary closure, the use of a mesh is inevitable. Although primary closure is adaptable for relatively small defects, it is difficult to suture the hernial orifice in which the anterior rim is absent. Herein, we present the case of a patient(More)
KRAS mutations occur in 30-40% of all cases of human colorectal cancer (CRC). However, to date, specific therapeutic agents against KRAS-mutated CRC have not been developed. We previously described the generation of mouse models of colon cancer with and without Kras mutations (CDX2P-G22Cre;Apc(flox/flox); LSL-Kras(G12D) and CDX2P-G22Cre;Apc(flox/flox) mice,(More)
Epithelial ovarian cancer is an aggressive gynecological malignancy with a high mortality rate. Resistance against chemotherapeutic agents often develops in ovarian cancer patients, contributing to high recurrence rates. The multidrug resistance 1 (MDR1/ABCB1) gene encodes P-glycoprotein, which affects the pharmacokinetic properties of anticancer agents. We(More)
