Treatment effect waning (TEW) refers to the attenuation of treatment effects over time. Assumptions of a sustained immuno-oncologic treatment effect have been a source of contention in health technology assessment (HTA). We review how TEW has been addressed in HTA and in the wider scientific literature.

Objectives: Here we describe treatment and survival of patients with advanced EAC, GEJC, and GAC to provide population-based evidence on distinctions and similarities between these populations.
Design: Retrospective cohort study of patients with unresectable advanced (cT4b) or metastatic (cM1) EAC, GEJC, or GAC (2015-2020) were selected from the Netherlands Cancer Registry.
Background: Gastric cancer (GC), gastroesophageal junction cancer (GEJC), and esophageal adenocarcinoma (EAC), together, are leading causes of cancer deaths worldwide. Patient health-related quality of life (HRQoL) and well-being has become increasingly important alongside traditional oncologic outcomes for both patients and clinicians and may aid treatment decisions. We conducted a survey to examine the clinical characteristics, humanistic burden, and the effects of first-line (1L) treatment in patients with GC/GEJC/EAC, across different geographic regions, to address the paucity of real-world data.

Here, an approach based on machine learning to produce a fast-executing model is introduced that predicts the polarization and energy of the radiated light produced at an insertion device. This paper demonstrates how a machine learning model can be trained on simulated data and later calibrated to a smaller, limited measured data set, a technique referred to as transfer learning.
