Predictive markers of response to immune checkpoint inhibitor rechallenge in metastatic non-small cell lung cancer.

Aim: The present study aims to evaluate the efficacy of rechallenge with immune checkpoint inhibitors (ICIs) compared to chemotherapy and the predictive role of clinical parameters in non-small cell lung cancer (NSCLC) patients who were rechallenged.

Methods: The study included 113 metastatic NSCLC patients who had initially responded to ICIs and platinum-based chemotherapy, either in combination in the first line or sequentially in the first and second line, but later experienced disease progression. Of those patients, 52 later received ICI rechallenge and 61 were exposed to chemotherapy.

Capmatinib in MET exon 14-mutated non-small-cell lung cancer: final results from the open-label, phase 2 GEOMETRY mono-1 trial.

Background: Capmatinib has previously shown activity in treatment-naive and previously treated patients with non-small-cell lung cancer (NSCLC) and a MET exon 14-skipping mutation (METex14). Here, we report the final outcomes from the phase 2 GEOMETRY mono-1 study with an aim to provide further evidence for the activity of capmatinib.

Methods: In this non-randomised, multi-cohort, open-label, phase 2 trial conducted in 152 centres and hospitals in 25 countries, with patients treated in 95 centres in 20 countries, eligible patients (aged ≥18 years) with MET-dysregulated, EGFR wild-type, and ALK rearrangement-negative advanced NSCLC (stage IIIB/IV) and an Eastern Cooperative Oncology Group performance status of 0 or 1 were assigned to cohorts (1a, 1b, 2, 3, 4, 5a, 5b, 6 and 7) based on their MET status (METex14 or MET amplification) and previous therapy lines.

Morphological changes of endometriomas during pregnancy and after delivery detected using ultrasound.

Objective: To assess changes in morphology and size of endometriomas during pregnancy and after delivery.

Design: This was a prospective observational cohort study performed during 2013-2024 at a tertiary care center (Ultrasound Unit, Department of Obstetrics and Gynecology, Skane University Hospital, Malmo, Sweden). Women were offered repeated ultrasound examinations every month during pregnancy and thereafter at 3 and 12 months after delivery.

The Structure and Optical Properties of Luminescent Europium Terephthalate Antenna Metal-Organic Frameworks Doped by Yttrium, Gadolinium, and Lanthanum Ions.

New heterometallic antenna terephthalate MOFs, namely, (EuM)bdc·4HO (M = Y, La, Gd) (x = 0.001-1), were synthesized by a one-step method from aqueous solutions. The resulting compounds are isomorphic to each other; the crystalline phase corresponds to Lnbdc∙4HO.

Current status of molecular diagnostics for lung cancer.

The management of lung cancer (LC) requires the analysis of a diverse spectrum of molecular targets, including kinase activating mutations in , (), and oncogenes, G12C substitutions, and , , and gene fusions. Administration of immune checkpoint inhibitors (ICIs) is based on the immunohistochemical (IHC) analysis of PD-L1 expression and determination of tumor mutation burden (TMB). Clinical characteristics of the patients, particularly age, gender and smoking history, significantly influence the probability of finding the above targets: for example, LC in young patients is characterized by high frequency of kinase gene rearrangements, while heavy smokers often have G12C mutations and/or high TMB.
