Background:

The European Society of Medical Oncology Scale for Clinical Actionability of Molecular Targets (ESCAT) classification system provides a standardized framework for categorizing genomic alterations (GAs) of patients with recurrent, metastatic, or rare cancer. This study aimed to present outcomes of patients discussed at the molecular tumor board (MTB) in general and according to ESCAT.

Patients And Methods:

We included 1226 patients with recurrent and/or metastatic cancer presented at the MTB from 2018 to 2022. Clinical and demographic data collected included age, gender, type of specimen, tumor type, number of prior treatments received, techniques used for molecular analyses, GAs identified, MTB recommendations, and inclusion or not into a clinical trial. The clinical endpoints collected were overall response rate (ORR), progression-free survival (PFS), and overall survival (OS), and were correlated with ESCAT.

Results:

Successful molecular profiling was carried out in 895 of 1226 (73%) patients. Actionable GAs were found in 595 (49%) patients, and 206 (17%) patients were oriented to matched therapies. Eventually, 101 (8%) patients received a matched therapy. For these patients, PFS and OS were significantly longer for GAs classified as ESCAT tiers I/II, compared with tiers III/IV (P = 0.009 and P = 0.014, respectively).

Conclusions:

Detection of actionable GAs through MTB molecular screening enabled to treat 8% of patients with matched therapy. Patients treated with matched therapy based on ESCAT tiers I/II had statistically longer PFS and OS, compared with ESCAT tiers III/IV.

Molecular and Ionic Solids

Crystalline solids are divided into four types: molecular, ionic, metallic, and covalent network based on the type of constituent units and their interparticle interactions.
Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...

Kinetic Molecular Theory: Molecular Velocities, Temperature, and Kinetic Energy

The kinetic molecular theory qualitatively explains the behaviors described by the various gas laws. The postulates of this theory may be applied in a more quantitative fashion to derive these individual laws.
