Prognostic Value of Metabolic Information in Advanced Gastric Cancer Using Preoperative 18 F-FDG PET/CT

ConclusionHigh SUVmax and high MTV of the primary tumor suggest a high risk of recurrence for AGC patients. Even if SUVmax is similar, the prognosis may vary depending on MTV. Combining PET parameters results in a better prediction for prognosis.

Abstract OBJECTIVES: To assess metastatic involvement of perigastric lymph nodes (PLNs) in patients with T1 gastric cancer by using CT perfusion imaging (CTPI). METHODS: A total of 82 annotated PLNs of 33 patients with T1 gastric cancer confirmed by endoscopic ultrasonography (EUS) underwent CTPI and portal Phase CT scan before operation. The scan data were postprocessed to acquire perfusion maps and calculate perfusion parameters including blood flow (BF) and permeability surface (PS). A radiologist measured the short axis diameters and perfusion parameters of PLNs. According to the post-operative pathology ...

Conclusion: Our data suggest that lean body mass can be a relevant prognostic factor in patients with gastric or esophageal cancer, and that CT measurements should be included in the routine preoperative evaluation, because it may provide information that aids nutritional and clinical care for these patients.Resumo Objetivo: Investigar se medidas antropom étricas e tomografia computadorizada (TC) da composição corporal podem predizer morbimortalidade pós-operatória em pacientes com câncer gástrico e/ou esofágico. Materiais e Métodos: Estudo retrospectivo que rev...

A 50-year-old woman presented with stomach discomfort. The patient had undergone a lobular breast cancer (LBC) surgery 17 years previously. On physical examination, mild upper abdominal tenderness was detected. Laboratory tests did not show any notable findings. Abdominal computed tomography scan revealed a gastric wall thickening (Fig. 1A, arrow). Esophagogastroduodenoscopy showed diffuse hypertrophic gastric folds (Fig. 1B). Biopsy specimens from the folds showed a poorly differentiated adenocarcinoma (Fig.

Rationale: Migration of endoclips and stitches into the duodenum after laparoscopic hepatectomy is incredibly rare with a poorly understood mechanism. Patient concerns: A 56-year-old woman who underwent laparoscopic left hepatectomy and cholecystectomy in August 2016 was admitted to our hospital with nausea and vomiting in December 2017. Diagnoses: Abdominal computed tomography (CT) scan showed high density shades in duodenal ampulla. Esophagogastroduodenoscopy showed deformation of the duodenal ampulla into two lumens; hem-o-lock clips and stitches were detected in the upper lumen. Contrast enhanced CT scan reveal...

Computed tomographic (CT) imaging at third lumbar vertebra (L3), routinely used by oncologists, represents a reliable tool to quantify muscle mass. A systematic review and meta-analysis was performed to assess the efficacy of CT scan to define muscle mass as a prognostic marker in GC patients undergoing gastrectomy and/or chemotherapy. The primary outcomes were overall survival (OS) and recurrence-free survival (RFS) and the secondary outcomes included postoperative length of hospital stay (P-LOS), total and severe complications in GC patients undergoing gastrectomy.

CONCLUSIONS: Our model-based patient selection tool is able to predict who might be at risk of exceeding dose-constraints during SBRT. It is a promising tool to tailor LAPC treatments, e.g. by employing online adaptive SBRT; and hence, to minimize toxicity of patients being at risk. PMID: 31606227 [PubMed - as supplied by publisher]

We present the exact course of a spontaneous rupture of the eyeball with choroidal metastasis from gastric carcinoma (GC) and the applied surgical interventions. Patient concerns: A 59-year-old male presented with pain and vision loss on his left eye for 6 months. He was diagnosed with GC, for which he received systemic chemotherapy for a year. Diagnoses: Preoperative B-scan, color fundus photography, computed tomography, and magnetic resonance imaging showed a choroidal tumor in his left eye. The spontaneous rupture of the corneoscleral limbus from 2 to 5 o’clock, combined secondary glaucoma, exudative retinal...
