Development and Validation of a Radiomics Nomogram for Preoperative Prediction of Lymph Node Metastasis in Colorectal Cancer Gastrointestinal Cancer

Purpose To develop and validate a radiomics nomogram for preoperative prediction of lymph node (LN) metastasis in patients with colorectal cancer (CRC). Patients and Methods The prediction model was developed in a primary cohort that consisted of 326 patients with clinicopathologically confirmed CRC, and data was gathered from January 2007 to April 2010. Radiomic features were extracted from portal venous–phase computed tomography (CT) of CRC. Lasso regression model was used for data dimension reduction, feature selection, and radiomics signature building. Multivariable logistic regression analysis was used to develop the predicting model, we incorporated the radiomics signature, CT-reported LN status, and independent clinicopathologic risk factors, and this was presented with a radiomics nomogram. The performance of the nomogram was assessed with respect to its calibration, discrimination, and clinical usefulness. Internal validation was assessed. An independent validation cohort contained 200 consecutive patients from May 2010 to December 2011. Results The radiomics signature, which consisted of 24 selected features, was significantly associated with LN status (P

ConclusionsPreoperative sarcopenia is an independent prognostic factor of postoperative morbidity and shorter survival in CRC peritoneal metastasis patients treated with CRS –HIPEC. Our findings support the importance of preoperative screening for sarcopenia as part of preoperative risk assessment for better selection of CRS–HIPEC candidates or treatment modifications in CRC patients with peritoneal metastasis.

AbstractThe aim of the study was to evaluate the ability to detect extra-cardiac foci by means of whole-body18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) in patients with definite endocarditis (IE) according to the modified Duke criteria and investigate the clinical impact of the findings. From January 2011 to December 2015 we included 178 patients (mean age 66  ± 14 years, 25% female) with IE in this multicentre study. FDG-PET/CT was part of the work-up for extra-cardiac foci in the including hospitals and was performed at a median of 9 days (IQR 10) af...

CONCLUSIONS: Although the whole-body PET/MRI was more accurate than the pelvic MRI alone for the prediction of tumor and node response to preoperative chemoradiotherapy, the technique performed worse than CT in detecting small lung metastasis.

This study presents a case of prostate carcinoma and the tumour remission observed after administration of a personalised Dendritic cell vaccine (APCEDEN). Patient concerns: A 58 years old Caucasian male diagnosed with prostate carcinoma with GLEASON score 8. The patient had previously been diagnosed with Renal Cell Carcinoma (RCC) in 1996 and had undergone nephrectomy of the right kidney. PET CT scan revealed multiple intensely PSMA avid lesions noted in both lobes of the prostate gland with SUVmax −28.3 and the prostate gland measuring 3.2 × 3.2 cm displaying maximum dimensions. Diagnosis: FNAC fo...

CONCLUSION: For radiotherapy treatment of localized prostate cancer in patients with hip prosthesis, the dose distribution was better in the VMAT and MAR- CT image methods than the conventional methods. Because the anatomical structure of the male pelvic region is relatively constant among individuals, we consider that VMAT is a valid treatment plan despite analyzing just three cases.

The majority of doctors will tell you that there is nothing you can do to reverse fatty liver and that health problems such as cirrhosis and liver failure may be in your future that they will address with the awful “solution” of liver transplant. The truth is the opposite: fatty liver is easily and readily reversible in virtually everybody, provided you take action before irreversible changes take place and are given the right information and tools. In this video, I discuss the three basic phenomena that drive fat deposition, liver damage, and inflammation that lead to this condition: Carbohydrate consumption ...
