Undifferentiated carcinoma of the pancreas (UDC) is rare and has a dismal prognosis. Here, we report a case of 6-year disease-free survival with a mixed type of UDC and UDC with osteoclast-like giant cells, with a high mitotic index as well as perineural, lymphatic, vessel, and diaphragmatic invasion. The patient underwent radical distal pancreatectomy and… (More)
BACKGROUND Pancreatic cancer accompanied by a moderate-sized pseudocyst with extrapancreatic growth is extremely rare. Diagnosis of pancreatic cancer on preoperative imaging is difficult when the pancreatic parenchyma is compressed by a pseudocyst and becomes unclear. Despite advances in imaging techniques, accurate preoperative diagnosis of cystic lesions… (More)
BACKGROUND Although many surgical procedures are now routinely performed laparoscopically, pure laparoscopic pancreaticoduodenectomy (LPD) is not commonly performed because of the technical difficulty of pancreatic resection and the associated reconstruction procedures. Several pancreatic-enteric anastomosis techniques for LPD have been reported, but most… (More)
BACKGROUND We investigated the patterns and predictors of recurrence and survival in cryptogenic non-B, non-C, non-alcoholic hepatocellular carcinoma (CR-HCC). We compared the findings with those hepatitis virus B (B) and hepatitis virus C (C)-HCC. CR-HCC does not include HCC developed on NASH. METHODS From 1990 to 2011, of 676 patients who underwent… (More)
KEY CLINICAL MESSAGE We propose that surgical resections of peritoneal metastases arising from hepatocellular carcinoma are an option for selected patients with controlled HCC in the liver, and without metastases in other organs, when the complete removal of such metastases can be achieved, especially in the case of patients with normal liver function.
