RETRACTED ARTICLE: The diagnostic nomogram of platelet-based score models for hepatic alveolar echinococcosis and atypical liver cancer

Abstract

Hepatic alveolar echinococcosis (HAE) and liver cancer had similarities in imaging results, clinical characteristics, and so on. And it is difficult for clinicians to distinguish them before operation. The aim of our study was to build a differential diagnosis nomogram based on platelet (PLT) score model and use internal validation to check the model. The predicting model was constructed by the retrospective database that included in 153 patients with HAE (66 cases) or liver cancer (87 cases), and all cases was confirmed by clinicopathology and collected from November 2011 to December 2018. Lasso regression analysis model was used to construct data dimensionality reduction, elements selection, and building prediction model based on the 9 PLT-based scores. A multi-factor regression analysis was performed to construct a simplified prediction model, and we added the selected PLT-based scores and relevant clinicopathologic features into the nomogram. Identification capability, calibration, and clinical serviceability of the simplified model were evaluated by the Harrell’s concordance index (C-index), calibration plot, receiver operating characteristic curve (ROC), and decision curve. An internal validation was also evaluated by the bootstrap resampling. The simplified model, including in 4 selected factors, was significantly associated with differential diagnosis of HAE and liver cancer. Predictors of the simplified diagnosis nomogram consisted of the API index, the FIB-4 index, fibro-quotent (FibroQ), and fibrosis index constructed by King’s College Hospital (King’s score). The model presented a perfect identification capability, with a high C-index of 0.929 (0.919 through internal validation), and good calibration. The area under the curve (AUC) values of this simplified prediction nomogram was 0.929, and the result of ROC indicated that this nomogram had a good predictive value. Decision curve analysis showed that our differential diagnosis nomogram had clinically identification capability. In conclusion, the differential diagnosis nomogram could be feasibly performed to verify the preoperative individualized diagnosis of HAE and liver cancer.

Evaluation of inflammatory parameters in patients with hepatic hydatid disease

“…Hydatid disease (HD) is a zoonotic parasitic disease caused by the adult or larval stages of Echinococcus cestodes. In recent years, HD has become a common and near-cosmopolitan disease that seriously endangers public health and brings economic burden [ 1 ]. China, as one of the countries representing high risks, is estimated to account for 91% of the global incidence [ 2 , 3 ].…”

Extrahepatic alveolar echinococcus on multi-slice computed tomography and magnetic resonance imaging

“…The mean age of the patients was 41 years (range 21–74 years) and 54.5% were men. Tilmann Graeter had also reported that the mean age of the patients was 50 years (range 21–74 years) and 56.2% were men 12 . Tilmann Graeter’s study was a multicenter study, including German, French, and Chinese patients, but our study is a single-center study of larger cases.…”

Development and validation of a Nomogram for predicting the Overall Survival of Patients With Pancreatic Ductal Adenocarcinoma of the Head of the Pancreas

“…[26,27] At present, nomogram is widely used to predict the survival outcome of patients with various tumors, such as lung cancer, breast cancer, and liver cancer. [28][29][30] In this study, we constructed a nomogram of the survival outcomes of patients with PDAC-HP based on 33,893 American patients with PDAC-HP in the SEER database. The results of the study showed that eight variables proved to be independent prognostic factors, including age at diagnosis, sex, race, marital status at diagnosis, AJCC staging, surgery, radiotherapy and chemotherapy.…”
