Proton magnetic resonance spectroscopy (H-MRS) has demonstrated that , lung cancer has higher lactate and choline signals than those of normal tissues. The detection of these metabolites in lung cancer by H-MRS would be useful for clinical diagnoses of lung cancer. We report the detection of lactate and choline in lung cancer by H-MRS in a 41-year-old Asian man who was diagnosed with pT4N0M0 ⅢA stage, right upper lobe lung adenocarcinoma. A lactate-lipid peak was observed near 1.33 ppm in the spectrum of lung cancer at TE = 30 ms, and it was inverted at TE = 135 ms, indicating that a lactate signal is contained in the lactate-lipid peak. A choline peak was also observed near 3.2 ppm in the spectrum with fat suppression at TE = 135 ms. An accumulation of similar cases will help determine the appropriate applications of H-MRS for lung cancer.

The aim of the present study was to investigate the efficacy and safety of anlotinib combined with vinorelbine (NVB) as a second-line treatment for elderly patients with advanced squamous cell lung carcinoma (SqCLC). The present retrospective analysis included 48 elderly patients (aged ≥65 years) diagnosed with advanced SqCLC who received anlotinib in combination with NVB as a second-line therapy between January 2021 and December 2023. The primary endpoints assessed were overall survival (OS), progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR) and safety profile.

Background: The occurrence of immune-related adverse events (irAEs) seemed to be associated with better outcomes in advanced gastric cancer (AGC) patients. However, research focusing on the impact of the single-organ irAE (uni-irAE) or multi-organ irAEs (multi-irAEs) on the AGC outcome is relatively limited. In this study, we investigated individually the impact of the different irAEs on AGC survival as well as the co-occurrence patterns of multi-irAEs.

Background: Inflammation and immune evasion are associated with tumorigenesis and progression. The Systemic Inflammation Response Index (SIRI) has been proposed as a pre-treatment peripheral blood biomarker. This study aims to compare the relationship between SIRI, various serum biomarkers, and the prognosis of NSCLC patients before and after treatment.

The COVID-19 pandemic has had a global impact, with >771 million confirmed cases and 6 million deaths reported by October 2023. Cancer patients, due to their immunosuppressed status, face an increased infection risk and higher COVID-19 complications. The present study aimed to assess clinical outcomes in COVID-19-infected cancer patients, focusing on mortality rates and other aspects, providing valuable insight for better protection and outcomes.

Elevated inflammatory markers on blood tests and emergent computed tomography led to a diagnosis of acute mesenteric ischemia, and the patient passed away 7 h later. Skin mottling indicates decreased blood flow in the gastrointestinal tract and is observed during mesenteric ischemia.
