Background: Our goals were to measure the accuracy of specialist helical computed tomography (CT) in the preoperative staging of gastric cancer, to determine the relative benefit of progressive CT system technology, and to determine the magnitude of any learning curve in radiological interpretation.
Methods: One hundred patients (median age, 70 years; range 27-86 years; 68 male) underwent a preoperative CT (73 helical [hCT], 27 multislice [mCT]), performed by a single specialist radiologist, followed by surgery within 3 weeks. The strength of the agreement between the perceived CT stage and the histopathological stage was determined for each CT system and also for four serial cohorts of 25 patients, by the weighted Kappa statistic (Kw).
Results: The Kw values for T, N, M1 liver, and M1 peritoneal stage were 0.40, 0.18, 0.36, and 0.09 for hCT, compared with 0.57, 0.67, 0.66 (all P < 0.001), and 0.24 (P = 0.06) for mCT. Serial Kw for T and N stages improved from 0.26 and -0.14 in the first quartile of patients to 0.61 and 0.73 (P < 0.001) in the last quartile of patients.
Conclusion: The role of CT in the preoperative staging of gastric cancer is becoming stronger as CT technology improves.

Purpose: To assess and compare the diagnostic efficiency of histogram analysis of monochromatic and iodine images derived from spectral CT in predicting Ki-67 expression in gastric gastrointestinal stromal tumors (gGIST).
Methods: Sixty-five patients with gGIST who underwent spectral CT were divided into a low-level Ki-67 expression group (LEG, Ki-67 < 10%, n = 33) and a high-level Ki-67 expression group (HEG, Ki-67 ≥ 10%, n = 32). Conventional CT features were extracted and compared.

Background: GI cancers pose an increasing global health burden, with their impact on the working-age population (WAP) aged 15-64 years remaining largely unexplored despite the crucial role of this group in societal and economic well-being.
Objective: To assess trends and cross-country inequality in the global burden of six GI cancers from 1990 to 2021 among individuals in the WAP.
Design: The 2021 Global Burden of Disease study dataset was used to obtain estimates of GI cancer incidence and 95% uncertainty intervals, including the number of cases, crude incidence rate and age-standardised incidence rate (ASIR).

Background/aim: The effect of left ventricular systolic dysfunction (LVSD), a risk factor for postoperative mortality, in older adult patients with gastric cancer has not been fully elucidated. This study aimed to evaluate the impact of low preoperative left ventricular ejection fraction (EF) on short- and long-term outcomes in older adult patients with gastric cancer.
Patients And Methods: This retrospective study enrolled 237 older adult patients with gastric cancer (≥75 years old) who underwent preoperative echocardiography and curative gastrectomy.

Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama, Japan.
Background/aim: Body weight loss (BWL) after gastrectomy for gastric cancer (GC) decreases postoperative quality of life and survival in patients with GC. This study aimed to evaluate the effect of oral nutritional supplements composed of high protein on BWL in the early period following gastrectomy.
Patients And Methods: Pre- and postoperative body weight and skeletal muscle mass were measured using bioelectrical impedance analysis in patients undergoing radical gastrectomy for GC and analyzed retrospectively.
