Radio-resistance remains a major challenge in the effective treatment of lung cancer. Cancer-associated fibroblasts (CAFs), the predominant cellular components in solid tumors, play a crucial role in tumor treatment and resistance. Thus, understanding the interactions between CAFs and tumor cells is key to overcoming radio-resistance in lung cancer. Herein, we demonstrated that radiation exacerbates fibrosis and acted as a critical driver for fibroblast proliferation and migration by promoting tumor cell secretion of high mobility group box 1(HMGB1), a key regulator of tumor progression and metastasis. Mechanistic analysis revealed that HMGB1 activated the PI3K-AKT pathway via TLR4, driving the transformation of CAFs into myCAFs subtypes. To block HMGB1 and enhance radiotherapy, we encapsulated the HMGB1 inhibitor DPG into tumor-targeted liposomes (DPG-Lipo) for combined tumor radiotherapy. The results showed that HMGB1 inhibition not only prevented CAFs activation and boosted radiotherapy effectiveness but also promoted immune infiltration, including CD8 T cells and DCs. Additionally, the reduction of MMP2 and VEGF in tumor tissues further suggested that combined targeted therapy could also inhibit tumor metastasis and invasion. Our findings reveal the relationship between lung cancer radio-resistance and CAFs, highlighting the significance of targeting HMGB1 to inhibit CAFs in enhancing radiotherapy sensitivity.

Background: Large cell neuroendocrine carcinoma (LCNEC) represents a rare and unique type of lung tumor with an unfavorable prognosis. It is essential to summarize the treatment modalities and prognosis for inoperable stage III and IV LCNEC, explore the role of frontline immunotherapy, and examine the stratification role of the Lung Immune Prognostic Index (LIPI) and its relationship with the tumor microenvironment (TME).
Methods: This study retrospectively analyzed 160 patients with inoperable lung LCNEC (L-LCNEC) admitted to three hospitals from December 2012 to November 2023.

Introduction: Psychiatric comorbidities are increasingly recognized in patients with thoracic malignancies. We undertook this scoping review to characterize the management of thoracic malignancies in patients with psychiatric illness and uncover any disparities in operative treatment or perioperative outcomes.
Methods: We conducted a scoping review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

With the advancements of next-generation sequencing, publicly available pharmacogenomic datasets from cancer cell lines provide a handle for developing predictive models of drug responses and identifying associated biomarkers. However, many currently available predictive models are often just used as black boxes, lacking meaningful biological interpretations. In this study, we made use of open-source drug response data from cancer cell lines, in conjunction with KEGG pathway information, to develop sparse neural networks, K-net, enabling the prediction of drug response in EGFR signaling pathways and the identification of key biomarkers.

Background: Amrubicin monotherapy has been used in Japan for patients with refractory, relapsed, small cell lung cancer (SCLC). However, the clinical guidelines do not specify a recommended initial dose for elderly patients. This retrospective study aimed to explore the appropriate initial dose of amrubicin for elderly patients with refractory, relapsed SCLC.

Lung cancer, as one of the cancers with the highest morbidity and mortality rates in the world, requires accurate detection of its vital serum marker, neuron-specific enolase (NSE), which is a key challenge for early detection of lung cancer. However, traditional chemiluminescence immunoassay (CLIA) methods rely on labeled antibodies (Abs) and suffer from complex operations and high costs. In this work, a label-free CLIA based on CL-functionalized mesoporous magnetic nanoparticles (CuFeO@mSiO-Cys-Luminol-Au NPs) is developed for the rapid and sensitive detection of NSE.
