Radiomics and Machine Learning for prediction of two-year disease-specific mortality and KRAS mutation status in metastatic colorectal cancer.

Purpose: Colorectal cancer is usually accompanied by liver metastases. The prediction of patient evolution is essential for the choice of the appropriate therapy. The aim of this study is to develop and evaluate machine learning models to predict KRAS gene mutations and 2-year disease-specific mortality from medical images.

Severe toxicity in adult patients with lung cancer under treatment with pemetrexed: a prospective cohort study.

Pemetrexed is an antimetabolite approved for treatment of non-small cell lung cancer. Harbouring interindividual variability in both the pharmacokinetic and pharmacogenetic profiles may lead to life-threatening toxicities. A prospective cohort study of adult patients initiating treatment with pemetrexed in combination with platinum between 2013 and 2015 were follow up.

Universal determination of microsatellite instability using BAT26 as a single marker in an Argentine colorectal cancer cohort.

Microsatellite instability (MSI) is a hallmark tool for Lynch syndrome (LS) screening and a prognostic marker for sporadic colorectal cancer (CRC). In regions with limited resources and scarce CRC molecular characterization as South America, the implementation of universal MSI screening is under debate for both its purposes. We sought to estimate the frequency of BAT26 in colorectal adenocarcinomas and to determine associated clinical and histological features.

Prediction of severe toxicity in adult patients under treatment with 5-fluorouracil: a prospective cohort study.

5-Fluorouracil (5-FU) has long been used for the treatment of gastrointestinal tumors harboring interindividual variability in both the pharmacokinetic and the pharmacogenetic profiles, which in turn may lead to life-threatening toxicities. We carried out a prospective cohort study of adult patients initiating treatment with 5-FU between 2013 and 2015. Primary exposures of interest were the methylenetetrahydrofolate reductase single nucleotide polymorphism in exons 4 and 7 and 5'-untranslated region-thymidylate synthase VNTR genotypes, in addition to baseline clinical and demographic variables.
