PURPOSE A low expression level of cyclin-dependent kinase (Cdk) inhibitor p27 is associated with high aggressiveness and poor prognosis of various carcinomas. Human Cdk subunit 1 (Cks1), as well as S-phase kinase-associated protein 2 (Skp2), is an essential and specific factor in the p27 proteolysis by SCF(Skp2) ubiquitin ligase. The purpose of this study(More)
The clinical significance of isolated tumor cells (ITC) circulating in the blood of patients with colorectal cancer is unclear. In this study, we investigated the relationship between the presence of ITC that express carcinoembryonic antigen (CEA) and/or cytokeratin 20 (CK20) transcripts in the blood and the clinicopathological findings and prognosis using(More)
Despite advances in treatment, postoperative pneumonia remains a major problem after esophagectomy. Lung age has been proposed as a comprehensive indicator for respiratory function. The aim of this study is to reveal the efficacy of lung age in predicting occurrence of pneumonia after esophagectomy. We assessed 342 consecutive patients who underwent(More)
The genetic alterations that occur during esophageal tumorigenesis have yet to be determined. We previously established a Wister rat carcinogenesis model of esophageal squamous cell carcinoma. To understand more about the molecular mechanisms during carcinogenesis, we produced esophageal neoplastic lesions by administering N-amyl-N-methylnitrosamine and(More)
Excessive visceral fat may promote cancer development and progression because of metabolic derangements. The purpose of this study was to clarify the impact of abdominal fat distribution on patient prognosis after esophagectomy for esophageal squamous cell carcinoma (ESCC). Computed tomography volumetry was performed in 150 patients who underwent curative(More)
When tracheal injury occurs during esophagectomy, it is a very serious and frequently fatal complication. We experienced a case of intractable tracheomediastinal fistula caused by tracheal injury during esophagectomy that was successfully repaired using a pedicle flap of the left pectoralis major muscle. A 55-year-old Japanese man who had congenital right(More)
Minimally invasive esophagectomy (MIE) is being increasingly performed worldwide. When performing MIE, we sometimes experienced difficulties due to a narrow upper mediastinum or a middle to lower thoracic esophagus hidden by the projection of the vertebral body. However, there were no reports regarding the influence of anatomical factors on the difficulty(More)
Pedicled jejunal flap and colon graft interposition are choices for esophageal reconstruction in patients with a history of gastrectomy or those who have undergone synchronous esophagogastrectomy. However, the optimal conduit in this situation is still being debated. We reviewed the literature concerning esophageal reconstruction using a conduit other than(More)
Esophagectomy for patients with esophageal cancer remains a high-risk surgery. We introduced a multidisciplinary perioperative management team in the Cancer Institute Hospital (PeriCan) to improve short-term outcomes after esophagectomy. To clarify the effect of PeriCan, we compared short-term outcomes between patients who underwent esophagectomy 1 year(More)
Intussusception is a rare cause of postoperative intestinal obstruction in adults. We experienced two cases of bowel obstruction due to the jejuno-jejunal intussusception after harvest of a free jejunum graft for reconstruction after cervical esophagectomy. Bowel obstruction occurred early in the postoperative course, and reoperations were needed in both(More)
