Acquisition of discrete immune suppressive barriers contributes to the initiation and progression of preinvasive to invasive human lung cancer.

Computerized chest tomography (CT)-guided screening in populations at risk for lung cancer has increased the detection of preinvasive subsolid nodules, which progress to solid invasive adenocarcinoma. Despite the clinical significance, there is a lack of effective therapies for intercepting the progression of preinvasive to invasive adenocarcinoma. To uncover determinants of early disease emergence and progression, we used integrated single-cell approaches, including scRNA-seq, multiplexed imaging mass cytometry and spatial transcriptomics, to construct the first high-resolution map of the composition, lineage/functional states, developmental trajectories and multicellular crosstalk networks from microdissected non-solid (preinvasive) and solid compartments (invasive) of individual part-solid nodules.

A robotic-assisted thymectomy is equivalent to a transsternal resection in large thymomas.

Background: Robotic-assisted thoracoscopic surgery (RATS) is widely accepted for small-to-moderate-size thymomas. However, limited data exists comparing the feasibility of RATS for large tumors ≥5 cm. The aim of this study is to compare the oncological and perioperative outcomes of open thymectomy (OT) versus RATS for these larger tumors.

Does High Standard Uptake Value on Positron Emission Tomography Preclude Sublobar Resection in Stage IA Non-Small Cell Lung Cancer ≤2 cm?

Background: Recent randomized trials have shown equivalent survival after sublobar resection vs lobectomy in patients with clinical stage IA non-small cell lung cancer (NSCLC) ≤2 cm. High maximum standard uptake value (SUVmax) is a known risk factor in NSCLC, yet limited data exist on whether a high SUV should preclude a sublobar resection. This study aimed to determine whether there is an association between SUVmax and survival based on the extent of parenchymal resection.
