Background:Early singular nodular hepatocellular carcinoma(HCC)is an ideal surgical indication in clinical practice.However,almost half of the patients have tumor recurrence,and there is no reliable prognostic prediction tool.Besides,it is unclear whether preoperative neoadjuvant therapy is necessary for patients with early singular nodular HCC and which patient needs it.It is critical to identify the patients with high risk of recurrence and to treat these patients preoperatively with neoadjuvant therapy and thus,to improve the outcomes of these patients.The present study aimed to develop two prognostic models to preoperatively predict the recurrence-free survival(RFS)and overall survival(OS)in patients with singular nodular HCC by integrating the clinical data and radiological features.Methods:We retrospective recruited 211 patients with singular nodular HCC from December 2009 to January 2019 at Eastern Hepatobiliary Surgery Hospital(EHBH).They all met the surgical indications and underwent radical resection.We randomly divided the patients into the training cohort(n=132)and the validation cohort(n=79).We established and validated multivariate Cox proportional hazard models by the preoperative clinicopathologic factors and radiological features for association with RFS and OS.By analyzing the receiver operating characteristic(ROC)curve,the discrimination accuracy of the models was compared with that of the traditional predictive models.Results:Our RFS model was based on HBV-DNA score,cirrhosis,tumor diameter and tumor capsule in imaging.RFS nomogram had fine calibration and discrimination capabilities,with a C-index of 0.74(95%CI:0.68-0.80).The OS nomogram,based on cirrhosis,tumor diameter and tumor capsule in imaging,had fine calibration and discrimination capabilities,with a C-index of 0.81(95%CI:0.74-0.87).The area under the receiver operating characteristic curve(AUC)of our model was larger than that of traditional liver cancer staging system,Korea model and Nomograms in Hepatectomy Patients with Hepatitis

Splenic hamartomas(SHs)are uncommon,benign vascular lesions of unclear etiology and are mostly found incidentally on abdominal images,at surgery,or at autopsy.Since the first case description,in 1861,less than 50 pediatric SH cases have been reported in the literature.In this article,we have performed an analysis of all SH cases in children published in the literature to date and presented our case of an 8-year-old male with SH.These lesions in children were shown to cause symptoms more often than in the adult population.The observed SH sizes in children ranged from a few millimeters to 18 cm,and the symptomatic lesions were mostly larger or multiple.The most common clinical finding was splenomegaly.Signs of hypersplenism were present in children with a single SH larger than 4.5 cm(diameter range:4.5-18.0 cm)and in those with multiple hamartomas,ranging from a few millimeters to 5 cm.Eighty percent of patients with available laboratory findings had hematological abnormalities such as anemia,thrombocytopenia,or pancytopenia.Other symptoms and signs included abdominal pain,recurrent infections,fever,night sweats,lethargy,growth retardation,and weight loss.The use of multiple imaging modalities may suggest the preoperative diagnosis of a splenic mass in children and determine the therapeutic approach.However,the final diagnosis of SH relies on histopathological evaluation.Surgery,including total or partial splenectomy(PS),is the mainstay of SH management.Milickovic M et al.Splenomas in children WJCC https://*** 1910 April 16,2024 Volume 12 Issue 11 Although total splenectomy carries a greater risk of overwhelming post-splenectomy infection than PS it has remained the most performed surgical procedure in children with SH.In the majority of pediatric patients with symptomatic SH,resolution of symptoms and resolution or improvement of cytopenias occurred after surgical treatment.

Sarcomatoid intrahepatic cholangiocarcinoma mimicking liver abscess: A case report

引用

World Journal of Clinical Cases 2020年第1期8卷 208-216页

Sarcomatoid intrahepatic cholangiocarcinoma(SICC)is an extremely rare and highly invasive malignant tumor of the liver.To our knowledge,the imaging findings of sarcomatous cholangiocarcinoma have been rarely reported;and radiological features of this tumor mimicking liver abscess have not yet been reported.CASE SUMMARY We present a case of SICC mimicking liver abscess.The patient,a 43-year-old male,complained of repeated upper right abdominal discomfort and intermittent distension over a period of one month.Radiology examination revealed a huge focal lesion in the right liver.The lesion was hypointense on computed tomography with honeycomb enhancement surrounded by enhanced peripheral areas.It showed a hypo-signal on non-contrast T1-weighted images and a hypersignal on non-contrast T2-weighted images.Radiologists diagnosed the lesion as an atypical liver abscess.The patient underwent a hepatectomy.After surgery,he survived another 2.5 mo before passing away.A search of PubMed and Google revealed 43 non-repeated cases of SICC reported in 20 published studies.The following is a short review in order to improve the diagnostic and therapeutic skills in cases of SICC.CONCLUSION This report presents the clinical and radiological features of SICC and imaging features which showed hypovascularity and progressive enhancement.SICC can present as a multilocular cyst on radiological images and it is necessary to distinguish this lesion from an atypical abscess.Simple surgical treatment is not the best treatment option for this disease.
