It is necessary to examine the characteristics of the dissemination nodules to establish a therapeutic strategy for peritoneal dissemination from digestive malignancy. Ki-67 expression as a proliferation marker in peritoneal dissemination nodules was investigated. The subjects were 15 patients with gastrointestinal cancers who underwent resection of the(More)
A schwannoma is a tumor that develops on peripheral nerves or spinal roots. Although any part of the body can be affected, the breast is a quite unusual site for schwannomas. We report herein a case of schwannoma presenting as a breast tumor. In the current case, the tumor showed both clinically and mammographically as a well-defined breast mass. Of(More)
BACKGROUND/AIMS In this study, we have attempted to identify and assess factors that would be most predictive of postoperative incisional surgical site infection (SSI) in colorectal surgery, including representative markers for nutrition or obesity. METHODS 152 patients who underwent elective colorectal resection were identified for inclusion in this(More)
We have previously demonstrated that the risk of incisional surgical site infection (SSI) increases with obesity and that the most useful predictor of incisional SSI is the thickness of subcutaneous fat. Based on this finding, we have recently attempted a closure technique in surgery for the obese in which a subcutaneous drain is inserted for the prevention(More)
BACKGROUND/AIMS Serum C-reactive protein (CRP) is an acknowledged marker of infections. For early detection of postoperative infections, CRP levels may be a useful marker. In this study, the CRP response with respect to wound infections (incisional surgical site infection (SSI)) in elective colorectal surgery was examined to define the role of serum CRP as(More)
BACKGROUND Adenoma of the nipple is a rare breast tumor that is often mistaken clinically for Paget's disease and misinterpreted pathologically as invasive ductal carcinoma. CASE REPORT We report herein a distinctive case of adenoma of the nipple projecting out of the nipple. In the current case, we were able to perform curative resection through a(More)
MicroRNA-7 (miR-7) has been reported to be a tumor suppressor in all malignancies including colorectal cancer (CRC). However, its significance for CRC clinical outcomes has not yet been explored. The potential for miR-7 to act as a tumor suppressor by coordinately regulating the epidermal growth factor receptor (EGFR) signaling pathway at several levels was(More)
AIM To evaluate the presence of extracapsular invasion (ECI) in positive nodes as a predictor of disease recurrence disease in colorectal cancer. METHODS Two hundred and twenty-eight consecutive patients who underwent colorectal resection were identified for inclusion in this study, of which 46 had positive lymph nodes. Among 46 cases with stage(More)
The optimal timing of early oral intake after surgery has not been fully established. The objective of this study was to compare early oral intake at postoperative day 1 after resection of colorectal cancer with that of day 2 to identify the optimal timing for resumption of oral intake in such patients. Consecutive patients with colorectal cancer who(More)
BACKGROUND/AIM Lymphatic invasion (ly) may mainly reflect the selective affinity of breast cancer cells for lymph nodes. We conducted the present study to investigate whether the presence of lymphatic invasion is a predictor of sentinel lymph node (SLN) metastasis in clinically node-negative breast cancer. PATIENTS AND METHODS We retrospectively evaluated(More)
