Efficacy of ramucirumab and subsequent nivolumab therapy in patients with advanced gastric cancer: A retrospective study.

Masaaki Saito Koichi Suzuki Sawako Tamaki Yasuaki Kimura Iku Abe Yuhei Endo Fumiaki Watanabe Toshiki Rikiyama

Molecular and clinical oncology 20(3) 17-17 2024年3月

Nivolumab monotherapy is a standard treatment of metastatic gastric cancer, and this type of cancer involves vascular endothelial growth factor (VEGF) signaling in the tumor immunological environment. The subgroup analysis of the ATTRACTION-2 tria...

A postoperative body weight increase is a novel risk factor for incisional hernia of midline abdominal incision after elective gastroenterological surgery.

Langenbeck's archives of surgery 408(1) 452-452 2023年11月

PURPOSE: Midline abdominal incisions (MAIs) are widely used in both open and minimally invasive surgery. Incisional hernia (IH) accounts for most long-term postoperative wound complications. This study explored the risk factors for IH due to MAI i...

Update of risk factors for surgical site infection in clean-contaminated wounds after gastroenterological surgery: An analysis of 1,878 participants enrolled in 2 recent randomized control trials for the prevention of surgical site infection.

BACKGROUND: Clean-contaminated wounds should be the main target for reducing the burden of harm caused by surgical site infection after gastroenterological surgery. METHODS: The present study targeted 1,973 patients enrolled in 2 randomized contro...

Implementation of intraoperative wound irrigation with aqueous 10% povidone-iodine and triclosan-coated sutures is not effective for reducing the incidence of incisional surgical site infection after major hepato-biliary-pancreatic surgery in patients with preoperative biliary drainage.

Hiroshi Noda Ryo Maemoto Kosuke Ichida Hidetoshi Aizawa Yuhei Endo Masahiro Iseki Shimpei Maeda Takarharu Kato Fumiaki Watanabe Toshiki Rikiyama

Journal of hepato-biliary-pancreatic sciences 30(6) 714-723 2023年6月

BACKGROUND/PURPOSE: Patients who receive preoperative biliary drainage (PBD) and biliary reconstruction are most at risk for incisional surgical site infection (SSI) in major hepatobiliary-pancreatic (HBP) surgery. METHODS: We evaluated 72 patient...

Circulating tumor DNA in molecular assessment feasibly predicts early progression of pancreatic cancer that cannot be identified via initial imaging.

Fumiaki Watanabe Koichi Suzuki Hidetoshi Aizawa Yuhei Endo Yuji Takayama Nao Kakizawa Takaharu Kato Hiroshi Noda Toshiki Rikiyama

Scientific reports 13(1) 4809-4809 2023年3月

Molecular assessment using circulating tumor DNA (ctDNA) has not been well-defined. We recruited 61 pancreatic cancer (PC) patients who underwent initial computed tomography (CT) imaging study during first-line chemotherapy. Initial molecular asse...
