ABSTRACT
Objective:To explore the prognostic value of tumor deposits (TD) by number and anatomical distribution in gastric cancer (GC) patients without lymph node metastasis.Methods:From Aug 2012 to Aug 2018 all 91 GC patients undergoing radical gastrectomy and without nodal metastasis at Yijishan Hospital of Wannan Medical College were enrolled in this study. Patients were divided into L1, L2, and L3 groups according to the number of TD and into Q1 and Q2 groups according to the anatomical regions of the TD.Results:The 3-year overall survival (OS) rates of groups L1, L2, and L3 were 58.9%, 52.1%, and 31.5%, respectively ( χ2=9.769, P=0.008). The 3-year OS rates of groups Q1 and Q2 were 58.9% and 7.1% ( χ2=46.310, P<0.001). The number of TD, their distribution, neural invasion, vascular invasion, tumor size, and pT stage were all related to prognosis by univariate analysis (all P<0.05). Tumor size>4 cm ( HR=2.460, 95% CI:1.307-4.629, P=0.005), distribution of TD (non-perigastric)( HR=3.959, 95% CI:2.077-7.545, P<0.001), neural invasion ( HR=4.299,95% CI:1.953-9.461, P<0.001), and pT 4 stage ( HR=2.283, 95% CI:1.250-4.171, P=0.007) were independent risk factors for prognosis by multivariate analysis. Conclusion:The distribution of TD (non-perigastric) is an independent risk factor for poor prognosis in gastric cancer patients after radical gastrectomy and with negative lymph node metastasis.
ABSTRACT
OBJECTIVE@#To explore the clinical and genetic characteristics of a fetus with Melnick-Needles syndrome (MNS).@*METHODS@#A fetus with MNS diagnosed at Ningbo Women and Children's Hospital in November 2020 was selected as the study subject. Clinical data was collected. Pathogenic variant was screened by using trio-whole exome sequencing (trio-WES). Candidate variant was verified by Sanger sequencing.@*RESULTS@#Prenatal ultrasonography of the fetus had shown multiple anomalies including intrauterine growth retardation, bilateral femur curvature, omphalocele, single umbilical artery, and oligohydramnios. Trio-WES revealed that the fetus has harbored hemizygous c.3562G>A (p.A1188T) missense variant of the FLNA gene. Sanger sequencing confirmed that the variant was maternally derived, whilst its father was of a wild type. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was predicted to be likely pathogenic (PS4+PM2_Supporting+PP3+PP4).@*CONCLUSION@#The hemizygous c.3562G>A (p.A1188T) variant of the FLNA gene probably underlay the structural abnormalities in this fetus. Genetic testing can facilitate accurate diagnosis of MNS and provide a basis for genetic counseling for this family.
