Journal ArticleDOI
D2 lymphadenectomy alone or with para-aortic nodal dissection for gastric cancer.
M. Sasako,Takeshi Sano,Seiichiro Yamamoto,Yukinori Kurokawa,Atsushi Nashimoto,Akira Kurita,Masahiro Hiratsuka,Toshimasa Tsujinaka,Taira Kinoshita,Kuniyoshi Arai,Yoshitaka Yamamura,Kunio Okajima +11 more
TL;DR: Treatment with D2 lymphadenectomy plus PAND does not improve the survival rate in curable gastric cancer, and no significant differences in recurrence-free survival are found.
Journal ArticleDOI
Gastric Cancer Surgery: Morbidity and Mortality Results From a Prospective Randomized Controlled Trial Comparing D2 and Extended Para-Aortic Lymphadenectomy—Japan Clinical Oncology Group Study 9501
Takeshi Sano,M. Sasako,Seiichiro Yamamoto,Atsushi Nashimoto,Akira Kurita,Masahiro Hiratsuka,Toshiinasa Tsujinaka,Taira Kinoshita,Kuniyashi Arai,Yoshitaka Yamamura,Kunio Okajima +10 more
TL;DR: Specialized surgeons could safely perform gastrectomy with D2 lymphadenectomy with para-aortic nodal dissection in patients with low operative risks without increasing major surgical complications in this setting.
Journal Article
Expression of N-acetylglucosaminyltransferase V in colorectal cancer correlates with metastasis and poor prognosis.
Kohei Murata,Eiji Miyoshi,Masao Kameyama,Osamu Ishikawa,Toshiyuki Kabuto,Yo Sasaki,Masahiro Hiratsuka,Hiroaki Ohigashi,Shingo Ishiguro,Satoru Ito,Hideo Honda,Fuminori Takemura,Naoyuki Taniguchi,Shingi Imaoka +13 more
TL;DR: Direct evidence is shown for the relationship between GnT-V and metastasis in human colorectal cancer and Screening of Gn T-V expression in coloreCTal cancer may provide useful information for prognosis of postoperative patients.
Journal ArticleDOI
Influence of Overweight on Surgical Complications for Gastric Cancer: Results From a Randomized Control Trial Comparing D2 and Extended Para-aortic D3 Lymphadenectomy (JCOG9501)
Toshimasa Tsujinaka,Mitsuru Sasako,Seiichiro Yamamoto,Takeshi Sano,Yukinori Kurokawa,Atsushi Nashimoto,Akira Kurita,Hitoshi Katai,Toshio Shimizu,Hiroshi Furukawa,Satoru Inoue,Masahiro Hiratsuka,Taira Kinoshita,Kuniyoshi Arai,Yoshitaka Yamamura +14 more
TL;DR: Surgical complications, operation time, and blood loss were statistically significantly associated with BMI, and logistic regression analysis revealed that overweight directly affected the occurrence of surgical complications even after considering operation time andBlood loss as intermediate factors instead of outcome variables.
Journal ArticleDOI
Expression of carbohydrate antigen sialyl Le(a): a new functional prognostic factor in gastric cancer.
Shoji Nakamori,H. Furukawa,Masahiro Hiratsuka,Takeshi Iwanaga,Shingi Imaoka,Osamu Ishikawa,Kabuto T,Yo Sasaki,Masao Kameyama,Shingo Ishiguro,T Irimura +10 more
TL;DR: Increased expression of the sLe(a) antigen may serve as a potent prognostic indicator for recurrence in patients with gastric cancer.
