Journal ArticleDOI

Masahiro Tsujiura,Daisuke Ichikawa,Shuhei Komatsu,Atsushi Shiozaki,Hideyuki Takeshita,Toshiyuki Kosuga,Hirotaka Konishi,R Morimura,K Deguchi,Hitoshi Fujiwara,Kazuma Okamoto,Eigo Otsuji +11 more
TL;DR: Detection of circulating miRNAs might provide new complementary tumour markers for GC, and they were significantly reduced in post-operative samples.
Journal ArticleDOI
Circulating microRNAs in plasma of patients with oesophageal squamous cell carcinoma
Shuhei Komatsu,Daisuke Ichikawa,Hideyuki Takeshita,Masahiro Tsujiura,R Morimura,H Nagata,Toshiyuki Kosuga,Daisuke Iitaka,Hirotaka Konishi,Atsushi Shiozaki,Hitoshi Fujiwara,Kazuma Okamoto,Eigo Otsuji +12 more
TL;DR: Detection of circulating miRNAs might provide new complementary tumour markers for ESCC by monitoring tumour dynamics through plasma miRNA assays.
Journal ArticleDOI
Clinical impact of circulating miR-221 in plasma of patients with pancreatic cancer.
Tsutomu Kawaguchi,Shuhei Komatsu,Daisuke Ichikawa,R Morimura,Masahiro Tsujiura,Hirotaka Konishi,Hideyuki Takeshita,H Nagata,Tomohiro Arita,Shoji Hirajima,Atushi Shiozaki,Hisashi Ikoma,Kazuma Okamoto,Toshiya Ochiai,Hiroki Taniguchi,Eigo Otsuji +15 more
TL;DR: Plasma miR-221 could be a useful biomarker for cancer detection, monitoring tumour dynamics and predicting malignant outcomes inPCa patients, and may contribute to clinical decision making in PCa treatments.
Journal ArticleDOI
Clinical impact of circulating miR-18a in plasma of patients with oesophageal squamous cell carcinoma
Shoji Hirajima,Shuhei Komatsu,Daisuke Ichikawa,Hideyuki Takeshita,Hirotaka Konishi,Atsushi Shiozaki,R Morimura,Masahiro Tsujiura,H Nagata,Tsutomu Kawaguchi,Tomohiro Arita,Takeshi Kubota,Hitoshi Fujiwara,Kazuma Okamoto,Eigo Otsuji +14 more
TL;DR: Plasma miR-18a may be a very useful biomarker for cancer detection and the monitoring of tumour dynamics in patients with ESCC.
Journal ArticleDOI
Surgical Outcomes of Gastrectomy for Elderly Patients with Gastric Cancer
Hiroki Takeshita,Daisuke Ichikawa,Shuhei Komatsu,Takeshi Kubota,Kazuma Okamoto,Atsushi Shiozaki,Hitoshi Fujiwara,Eigo Otsuji +7 more
TL;DR: The treatment results in elderly patients were comparable to those in nonelderly patients, suggesting that R0 resection with at least limited lymph node dissection according to Japanese guidelines should be considered, even for elderly patients.
