Background: Despite a potentially curative treatment, the prognosis after upfront surgery and adjuvant chemotherapy for patients with resectable pancreatic ductal adenocarcinoma (PDAC) is poor. Modified FOLFIRINOX (mFOLFIRINOX) is a cornerstone in the systemic treatment of PDAC, including the neoadjuvant setting. Pharmacokinetic-guided (PKG) dosing has demonstrated beneficial effects in other tumors, but scarce data is available in pancreatic cancer.

Article Synopsis
  • Medical students need effective learning strategies as university content increases, and adopting a Deep Approach (DA) and Self-Regulation (SR) can enhance student success.
  • A study at the University of Navarre analyzed responses from 155 third-year students, revealing that above-average students tended to favor DA over Surface Approach (SA) and scored higher in SR skills.
  • The findings suggest that curricula should be designed to promote DA and SR, encouraging a focus on understanding material rather than mere memorization.

Background: Reviews and meta-analysis conclude that distributed practice and practice testing are deemed the most effective learning techniques among undergraduate students, while rereading, underlining, and summarisation are the most known and less effective ones. However, this evidence is gathered from short-term retention studies prior to 2014, and there are other techniques with promising effect (metacognition, retrieval, concept mapping, setting learning goals) that were not included. Also, there is little real-settings evidence regarding what works best for long-term retention in medical students.

Background: Perioperative chemotherapy (CT) or neoadjuvant chemoradiotherapy (CRT) in patients with locally advanced gastric (GC) or gastroesophageal junction cancer (GEJC) has been shown to improve survival compared to an exclusive surgical approach. However, most patients retain a poor prognosis due to important relapse rates. Population pharmacokinetic-pharmacodynamic (PK/PD) modeling may allow identifying at risk-patients.

Preoperative radiochemotherapy and total mesorectal excision surgery is a recommended standard therapy for patients with locally advanced rectal cancer. However, some subgroups of patients benefit more than others from this approach. In order to avoid long-term complications of radiation and chemotherapy, efforts are being made to subdivide T3N0 stage using advanced imaging techniques, and to analyze prognostic factors that help to define subgroup risk patients.

Background: The finding that some rectal cancers respond to neoadjuvant chemoradiation is broadening new surgical options for the treatment of some of these tumors that, until now, required a total mesorectal excision. Nevertheless, a fine match between clinical and pathological response is required when planning conservative surgical approaches.

Objective: This study aims to prospectively validate the use of endoscopic ultrasound as a predictor of clinical and pathological tumor response in patients with locally advanced rectal cancer.
