Optimizing T cell inflamed signature through a combination biomarker approach for predicting immunotherapy response in NSCLC.
Sci Rep
December 2024
Interventional Oncology, Johnson & Johnson Enterprise Innovation, Inc, 10th Floor 255 Main St, 02142, Cambridge, Boston, MA, USA.
The introduction of anti-PD-1/PD-L1 therapies revolutionized treatment for advanced non-small cell lung cancer (NSCLC), yet response rates remain modest, underscoring the need for predictive biomarkers. While a T cell inflamed gene expression profile (GEP) has predicted anti-PD-1 response in various cancers, it failed in a large NSCLC cohort from the Stand Up To Cancer-Mark (SU2C-MARK) Foundation. Re-analysis revealed that while the T cell inflamed GEP alone was not predictive, its performance improved significantly when combined with gene signatures of myeloid cell markers.

BACKGROUND Arterioportal fistulas (APFs) are abnormal connections between the arterial and portal venous systems, leading to portal hypertension (PH) and symptoms such as gastrointestinal bleeding, splenomegaly, and hepatic pain. Symptoms typically appear by the age of 2 years in about 75% of cases. CASE REPORT A 7-year-old boy with an asymptomatic APF developed life-threatening complications following a Clostridium difficile infection.

Department of Surgery, Seoul Metropolitan Government-Seoul National University Boramae Medical Center, Boramae-ro 5-20, Dongjak-gu, Seoul, 07061, Republic of Korea.
Background: Osteoporosis, a frequent complication of gastrectomy, increases with age, and the average age of gastric cancer patients continues to rise. This study aims to analyze perioperative factors of osteoporosis after radical gastrectomy.
Materials And Methods: This retrospective cohort study included patients who underwent dual-energy-X-ray absorptiometry after gastrectomy due to gastric cancer between 2016 and 2019 at Seoul Boramae Medical Center.
Association of PD-1 + Treg/PD-1 + CD8 ratio and tertiary lymphoid structures with prognosis and response in advanced gastric cancer patients receiving preoperative treatment.

December 2024
Department of Gastrointestinal Surgery, School of Medicine, RenJi Hospital, Shanghai Jiao Tong University, 160 Pujian Road, Pudong New Area, Shanghai, 200025, China.
Background: Recent studies have highlighted the distinct ratio of PD-1 + Treg/PD-1 + CD8 for prognosis prediction. However, it remains unclear about the association of this ratio and tertiary lymphoid structures (TLS) with prognosis and response to neoadjuvant or conversion therapy in advanced gastric cancer.
Methods: Firstly, fresh postoperative samples from 68 gastric cancer patients in Renji Hospital were collected.
