BACKGROUND Few larger studies have estimated the incidence of incisional hernia (IH) after abdominal surgery. METHODS Patients who had abdominal surgery between November 2009 and February 2011 were included in the study. The incidence rate and risk factors for IH were monitored for at least 180  days. RESULTS A total of 4305 consecutive patients were(More)
OBJECTIVE This Phase II trial was designed to evaluate the safety and efficacy of neoadjuvant oxaliplatin and capecitabine and bevacizumab without radiotherapy in patients with poor-risk rectal cancer. METHODS Patients with magnetic resonance imaging-defined poor-risk rectal cancer received neoadjuvant oxaliplatin and capecitabine and bevacizumab followed(More)
OBJECTIVE To investigate whether immunohistochemically demonstrated lymph node micrometastasis has prognostic significance in patients with histologically node-negative (pN0) hilar cholangiocarcinoma. SUMMARY BACKGROUND DATA The clinical significance of immunohistochemically detected lymph node micrometastasis recently has been evaluated in various(More)
BACKGROUND Neoadjuvant chemotherapy for unresectable colorectal liver metastases can reduce tumor size, which sometimes leads to curative resection. The aim of the present study was to identify and describe patients with initially unresectable liver-only metastases from colorectal cancer who obtained sufficient chemotherapeutic benefit that eventually lead(More)
BACKGROUNDS Perioperative introduction of developed chemotherapy into the treatment strategy for locally advanced rectal cancer (LARC) may be a promising option. However, the most prevalent treatment for high-risk LARC remains preoperative chemoradiotherapy (CRT) in Western countries. PATIENTS AND METHODS A phase II trial was undertaken to evaluate safety(More)
In Western countries, the standard treatment for locally advanced rectal cancer is preoperative chemoradiotherapy followed by total mesorectal excision. On the other hand, in Japan, treatment results without radiotherapy are by no means inferior; therefore, extrapolation of results of preoperative treatment in Western countries to Japan is controversial. We(More)
PURPOSE We previously showed that S-1 after curative resection of colorectal liver metastasis had acceptable toxicity and a high rate of completion of therapy in a prospective phase II trial. We here reported the primary endpoint of disease-free survival (DFS). METHODS Between October 2008 and August 2010, 60 patients were eligible for this study and(More)
BACKGROUND Although, in Western countries, oxaliplatin-based regimens have been established as a gold standard treatment for patients with stage III or high risk stage II colon cancer after curative resection, in Japan fluorouracil-based regimens have been widely accepted and recommended in the guidelines for adjuvant settings in patients with stage III(More)
