Lung cancer ranks as the most common and lethal malignancy in America and worldwide. APOBEC3B is a newly identified DNA cytosine deaminase, which is supposed to function as a major source of DNA mutation in many different tumors. In this study, we combine the data of online databases and two hundred and twenty-one primary non-small-cell lung carcinoma (NSCLC) specimens from Sun Yat-sen University Cancer Center to investigate, for the first time, the clinical role of APOBEC3B in lung cancer. We found that the APOBEC3 expression was commonly elevated in NSCLC tissues and overexpression of APOBEC3B was correlated with unfavorable prognosis of the patients with NSCLC. Furthermore, APOBEC3B expression was associated with nodal status, TNM staging and adjuvant chemotherapy of the patients with NSCLC. Further research is warranted.

Background: Uncertainty in the diagnosis of lung nodules is a challenge for both patients and physicians. Artificial intelligence (AI) systems are increasingly being integrated into medical imaging to assist diagnostic procedures. However, the accuracy of AI systems in identifying and measuring lung nodules on chest computed tomography (CT) scans remains unclear, which requires further evaluation.

Lung adenocarcinoma (LUAD) is the most common histological subtype of nonsmall-cell lung cancer. Herein, a multiomics method, which combined proteomic and N-glycoproteomic analyses, was developed to analyze the normal and cancerous bronchoalveolar lavage fluids (BALFs) from six LUAD patients to identify potential biomarkers of LUAD. The data-independent acquisition proteomic analysis was first used to analyze BALFs, which identified 59 differentially expressed proteins (DEPs).

This study determined the characteristics of patients with early-stage melanoma (IA-IIA) who later had stage IV recurrence. We retrospectively examined 880 melanoma patients and identified those who progressed to stage IV disease from an initial early-stage (n = 50). We observed a median latent period of 4 years between early-stage diagnosis and metastatic disease.

Background: In Taiwan, as the population ages, palliative care services (PCS) have expanded significantly to include comprehensive benefit plans for critically ill individuals, supported by reimbursements from the National Health Insurance program. However, incorporating palliative care into the medical management of these patients presents several challenges. We aim to evaluate the effects of palliative care interventions on medical resources in end-of-life scenarios, to promote earlier palliative care access and provide high-quality healthcare services for patients.
