Prognostic Impact of Bone Mineral Density Reduction During Neoadjuvant Chemotherapy (NAC) in Patients Undergoing NAC Followed by Esophagectomy for Esophageal Cancer

Kazuhide Sato, Keita Takahashi, Yoshitaka Ishikawa, Naoko Fukushima et autres

ABSTRACT Background Our previous study suggested that low bone mineral density (BMD), known as osteopenia, was a poor prognostic factor in patients who underwent esophagectomy for esophageal cancer (EC). Meanwhile, the association between BMD reduction during neoadjuvant chemotherapy (NAC) and the worse …

Clinical impact of low fornix perfusion on devascularized whole stomach as a risk factor for anastomotic leakage after esophagectomy

Keita Takahashi, Masami Yuda, Yoshitaka Ishikawa, Takahiro Masuda et autres

Backgrounds: We previously reported poor vascularity of narrow gastric tube evaluated by thermography was associated with anastomotic leakage (AL) after esophagectomy. Meanwhile, the association between the fornix low perfusion on devascularized whole stomach (DWS) and the incidence of AL remains unclear. Therefore, …
