BACKGROUND Laparoscopic colorectal resection has been gaining popularity over the past two decades. However, studies about laparoscopic rectal surgery in elderly patients with long-term oncologic outcomes are limited. In this study, we evaluated the short-term and long-term outcomes of laparoscopic and open resection in patients with rectal cancer aged ≥ 70(More)
Multicellular organisms have multiple homologs of the yeast ATG8 gene, but the differential roles of these homologs in autophagy during development remain largely unknown. Here we investigated structure/function relationships in the two C. elegans Atg8 homologs, LGG-1 and LGG-2. lgg-1 is essential for degradation of protein aggregates, while lgg-2 has(More)
BACKGROUND A history of previous abdominal surgery (PAS) may increase the complexity of laparoscopic colorectal surgery. The aim of this study was to investigate the impact of PAS on the outcomes of laparoscopic colorectal resection for colorectal cancer. METHODS A total of 378 colorectal cancer patients (group A) with a history of PAS were 1:1 matched to(More)
Desmoid tumors are rare soft tissue tumors with limited data on their management and prognosis. We sought to determine the rates of recurrence after surgery for desmoid tumors and analyze factors predictive of recurrence-free survival (RFS). From February 1976 to October 2011, 233 consecutive patients with desmoid tumors who underwent macroscopically(More)
INTRODUCTION Preoperative chemoradiotherapy (CRT), followed by total mesorectal excision, has become the standard of care for patients with clinical stages II and III rectal cancer. Patients with pathologic complete response (pCR) to preoperative CRT have been reported to have better outcomes than those without pCR. However, the factors that predict the(More)
Laparoscopic resection for transverse colon cancer remains controversial. The aim of this study is to investigate the short- and long-term outcomes of laparoscopic surgery for transverse colon cancer. A total of 278 patients with transverse colon cancer from a single institution were included. All patients underwent curative surgery, 156 patients underwent(More)
BACKGROUND The aim of this study was to evaluate the effect of a longer interval between long-course neoadjuvant chemoradiotherapy and surgery on surgical and oncologic outcome. METHODS A total of 233 consecutive patients with clinical stage II and III rectal cancer were divided into 2 groups according to the neoadjuvant-surgery interval: short-interval(More)
BACKGROUND The lymph node ratio (LNR) has been shown to be an important prognostic factor for colorectal cancer. However, studies focusing on the prognostic impact of LNR in rectal cancer patients who received neoadjuvant chemoradiotherapy (CRT) followed by curative resection have been limited. The aim of this study was to investigate LNR in rectal cancer(More)
OBJECTIVE The efficacy of laparoscopic treatment of rectal cancer remains unclear, and little is known about its effect on sphincter preservation. We compared short-term outcomes of laparoscopically assisted and open surgeries following neoadjuvant chemoradiotherapy (CRT) for mid and low rectal cancer. METHODS This study enrolled 137 patients with mid-low(More)
BACKGROUND To investigate the feasibility, safety and short-term efficacy of laparoscopic techniques applied in the abdominoperineal resection (APR) for low rectal cancer. METHODS The clinical data of 236 patients with APR from January 2010 to January 2012 were analysed retrospectively, including 100 patients underwent laparoscopically assisted APR (LAAPR(More)
