Open gastric surgery in elderly patients is associated with higher morbidity and mortality rates than those reported among younger individuals. Therefore, minimally invasive surgery may have a larger impact on the elderly compared to the younger age group. The objective of this study was to evaluate the experience of laparoscopy-assisted distal gastrectomy(More)
Keratin 17 (K17) is regarded as a basal/myoepithelial cell keratin and is known to be inducible in activated keratinocytes. The high frequency of K17 expression in pancreaticobiliary nonmucinous adenocarcinoma or basal-like breast carcinoma has previously been described. However, its expression in gastric cancer (GC) is controversial. We investigated the(More)
The malignant potential of gastrointestinal stromal tumors (GISTs) is difficult to diagnose before surgery because the diagnoses are based on tumor diameter and mitotic index. The progression of small GISTs is always observed because they do not seem to have malignant potential. 18F-Fluorodeoxyglucose (FDG)-positron emission tomography (PET) is a useful(More)
Melanoma antigen-encoding gene-1 (MAGE-1), a cancer/testis antigen, has been reported to be expressed in various types of cancer. We investigated the clinicopathological features and prognostic significance of MAGE-1 expression in advanced gastric cancer (AGC). Immunohistochemical staining for MAGE-1 was performed on surgical specimens obtained from 135(More)
The prognosis of unresectable gastric cancer is poor. Chemotherapy occasionally converts an initially unresectable gastric cancer to a resectable cancer. The responses of noncurative factors to initial chemotherapy and the outcomes of additional (conversion) surgery were retrospectively evaluated in 151 patients with unresectable gastric cancer receiving(More)
