Background: Lung cancer risk is increased in COPD. However, it is not clear how COPD affects the course of lung cancer.
Aim: To determine whether the overall survival of stage 4 lung cancer patients differ in various COPD stages.
Study Design: A cross-sectional retrospective study.
Methods: We screened lung cancer patients with ICD code: C34 and included stage 4 lung cancer patients with histological diagnosis and pulmonary function tests at admission in the study. Demographic data, stages, metastasis sites and number of metastases, performance status, pulmonary function tests, Global Initiative for Chronic Obstructive Lung Disease (GOLD) stages, arterial blood gasses and treatment methods were recorded on a standardised database. We checked their dates of death from national database. Data were evaluated with SPSS programme version 18.
Results: Out of 900 patients, 146 patients had stage 4 disease at the time of diagnosis and, 127 patients had COPD. There was a significant difference between survivals of stage 4 cancer patients with different COPD stages. As COPD stage increased, overall survival worsened (P = 0.037). Factors affecting survival were bone metastasis (P = 0.01, OR = 1.72), liver metastasis (P = 0.04, OR = 1.87), brain metastasis (P = 0.001, OR = 2.6), having N 2-3 disease (P = 0.01, OR = 1.79) and GOLD 4 COPD (P = 0.01, OR = 2.28).
Conclusion: As COPD becomes more severe, overall survival rates of stage 4 patients worsen. Bone metastasis, liver metastasis, brain metastasis, having N2-3 disease and GOLD 4 COPD worsen the overall survival.

Tumor cell-intrinsic signaling pathways can drastically affect the tumor immune microenvironment, promoting tumor progression and resistance to immunotherapy by excluding immune-cell populations from the tumor. Several tumor cell-intrinsic pathways have been reported to modulate myeloid-cell and T-cell infiltration creating "cold" tumors. However, clinical evidence suggests that excluding cytotoxic T cells from the tumor core also mediates immune evasion.

Antibodies targeting immune checkpoints, such as PD-1, PD-L1, or CTLA-4, have transformed the treatment of patients with lung cancers. Unprecedented rates of durable responses are achieved in an imperfectly characterized population of patients with metastatic disease. More recently, immune checkpoint inhibitors have been explored in patients with resectable non-small-cell lung cancers.

Lung cancers associated with cystic airspaces (LCCAs) are a rare and relatively novel concept analyzed in various case reports and retrospective studies. In this review, it was our aim to investigate the morphologic, imaging, and clinicopathologic characteristics of this entity, as well as its natural course in light of the current literature. Literature search including the years 2000-2022 was conducted in PubMed.

Background: Telecytology-assisted rapid on-site evaluation (ROSE) offers a cost-effective method to enhance minimally invasive biopsies like fine needle aspiration and core biopsies with touch preparation. By reducing nondiagnostic sampling and the need for repeat procedures, ROSE via telecytology facilitates prompt triage for ancillary tests, improving patient management. This study examines cases initially deemed adequate for diagnosis during telecytology-assisted ROSE but later categorized as nondiagnostic at final evaluation (NDIS).

Determining mutations in the kinase domain of the epidermal growth factor receptor (EGFR) is critical for the effectiveness of EGFR tyrosine kinase inhibitors (TKIs) in lung cancer. Yet, DNA-based sequencing analysis of tumor samples is time-consuming and only provides gene mutation information on EGFR, making it challenging to design effective EGFR-TKI therapeutic strategies. Here, we present a new image-based method involving the rational design of a quenched probe based on EGFR-TKI to identify mutant proteins, which permits specific and "no-wash" real-time imaging of EGFR in living cells only upon covalent targeting of the EGFR kinase.
