Purpose: We performed a combined assessment of skeletal muscle mass using the skeletal muscle mass index (SMI) and the psoas muscle index (PMI) to evaluate their association with the overall survival (OS) of gastric cancer patients after curative gastrectomy.
Methods: We analyzed, retrospectively, the computed tomography records of skeletal muscle mass of patients who underwent radical gastrectomy for pStage I-III gastric cancer between April, 2010 and April, 2016. We then compared OS as the primary outcome, stratifying patients according to their SMI or PMI, and investigated prognostic factors using multivariate analyses.
Article Synopsis
- * The research included 4,663 patients who had radical gastrectomy for stages I-III gastric cancer, categorizing their preoperative prealbumin and C-reactive protein (CRP) levels to establish PPS scores, with lower scores indicating poorer survival.
- * Results showed that a higher PPS correlated with worse overall survival, with scores of one and two being independent indicators of poor prognosis, suggesting that PPS can better identify at-risk patients compared to mGPS after surgery
Background: Patients aged >80-years-old with gastric cancer are commonly excluded from clinical trials, and no consensus exists regarding surgical indications and outcomes in older patients. In this study, we analyzed the post-gastrectomy long-term survival and etiologies of mortality in older patients with gastric cancer.
Methods: Patients aged >80-years-old with pathological stages I-III primary gastric cancer who undergone radical gastrectomies, between May 2006 and March 2017, were included in the study.
Tokyo Electric Power Company, TEPCO, has started tritiated water release into the Pacific Ocean. In order to reduce unreasonable rumor caused by tritium release, flounder, abalone, and sarggasum were exposed to tritium enriched seawater, and time dependent Tissues Free Water Tritium (TFWT) concentration was measured. Estimating the concentration of Organically Bound Tritium (OBT) is important to assess tritium impact because it has a longer biological half-life than TFWT.

However, treatment intensity for S-1 as adjuvant chemotherapy has not as yet been compared between minimally invasive (MI) and open (Open) surgery.
Methods: We retrospectively compared dose modification of adjuvant S-1 between MI and Open surgery in patients undergoing R0 gastrectomy for gastric or esophago-gastric junction cancer at the Cancer Institute Hospital Tokyo, Japan, during the period from 2012 to 2022, and receiving S-1 for pStage II or S-1 plus docetaxel for pStage III as adjuvant chemotherapy.
