Theranostics with somatostatin receptor antagonists in SCLC: Correlation of Ga-SSO120 PET with immunohistochemistry and survival.

Positron Emission Tomography (PET) using the somatostatin receptor 2 (SSTR2)-antagonist satoreotide trizoxetan (Ga-SSO120) is a novel, promising imaging modality for small-cell lung cancer (SCLC), which holds potential for theranostic applications. This study aims to correlate uptake in PET imaging with SSTR2 expression in immunohistochemistry (IHC) and to assess the prognostic value of Ga-SSO120 PET at initial staging of patients with SCLC. We analyzed patients who underwent Ga-SSO120 PET/CT during initial diagnostic workup of SCLC as part of institutional standard-of-care.

Survivorship program including long-term toxicities and quality-of-life development over 10 years in a randomized trial in operable stage III non-small-cell lung cancer (ESPATUE).

Over 40% stage-III non-small-cell lung cancer (NSCLC) patients (pts) experience 5-year survival following multimodality treatment. Nevertheless, little is known about relevant late toxicities and quality-of-life (QoL) in the further long-term follow-up. Therefore, we invited pts from our randomized phase-III trial (Eberhardt et al.

Fibroblast Activation Protein-Directed Imaging Outperforms F-FDG PET/CT in Malignant Mesothelioma: A Prospective, Single-Center, Observational Trial.

The fibroblast activation protein (FAP) is highly expressed in tumor and stromal cells of mesothelioma and thus is an interesting imaging and therapeutic target. Previous data on PET imaging with radiolabeled FAP inhibitors (FAPIs) suggest high potential for superior tumor detection. Here, we report the data of a large malignant pleural mesothelioma cohort within a Ga-FAPI46 PET observational trial (NCT04571086).

Dielectric Properties of PEEK/PEI Blends as Substrate Material in High-Frequency Circuit Board Applications.

Substrate materials for printed circuit boards must meet ever-increasing requirements to keep up with electronics technology development. Especially in the field of high-frequency applications such as radar and cellular broadcasting, low permittivity and the dielectric loss factor are key material parameters. In this work, the dielectric properties of a high-temperature, thermoplastic PEEK/PEI blend system are investigated at frequencies of 5 and 10 GHz under dried and ambient conditions.
