Negative hyperselection of elderly patients with RAS and BRAF wild-type metastatic colorectal cancer receiving initial panitumumab plus FOLFOX or 5-FU/LV.

Background: Upfront anti-EGFR therapy represents the standard of care for patients with left-sided, MSS/pMMR, RAS and BRAF wild-type mCRC. Molecular 'hyperselection' may optimize EGFR inhibition by detecting additional resistance alterations.

Materials And Methods: We used comprehensive genomic profiling on archival samples of elderly patients enrolled in the PANDA trial to detect: HER2 amplification/mutations; MET amplification; NTRK/ROS1/ALK/RET rearrangements; PIK3CA exon 20 mutations; PTEN alterations; AKT1 mutations; MAP2K1 mutations.

ctDNA as promising tool for the assessment of minimal residual disease (MRD) and the need of an adjuvant treatment in gastroesophageal adenocarcinoma.

Gastroesophageal adenocarcinoma is a challenging disease due to its poor prognosis and the presence of few therapeutic options. For these reasons, it is mandatory to identify the subgroup of patients who are at high risk for relapse after curative-intention surgery. In the last years, liquid biopsy has aroused great interest in cancer treatment for its feasibility and the possibility to capture tumor heterogeneity in a real-time way.

Stress symptoms and Coronavirus disease 2019 (COVID-19): a comparative study between Attention Deficit Hyperactivity Disorder and typically developing children and adolescents.

Background: Coronavirus disease 2019 (COVID-19) related confinement severely impacted people wellbeing. Many studies focused on general population, although it is reasonable to expect that patients with neurodevelopmental disorders might have been at higher risk. Children/adolescents with Attention Deficit/Hyperactivity Disorder (ADHD) might be potentially more vulnerable, due to their intolerance to forced restrictions that limit stimulating experiences, to obligation to follow instructions and to acceptation of imposed rules We aimed to compare stress-related behavioral changes of the first COVD-19 related confinement among 6-18 years old ADHD and typically developing subjects.
