Immune checkpoint inhibitor (ICI) treatments benefit some patients with metastatic cancers, but predictive biomarkers are needed. Findings in selected cancer types suggest that tumor mutational burden (TMB) may predict clinical response to ICI. To examine this association more broadly, we analyzed the clinical and genomic data of 1,662 advanced cancer patients treated with ICI, and 5,371 non-ICI-treated patients, whose tumors underwent targeted next-generation sequencing (MSK-IMPACT). Among all patients, higher somatic TMB (highest 20% in each histology) was associated with better overall survival. For most cancer histologies, an association between higher TMB and improved survival was observed. The TMB cutpoints associated with improved survival varied markedly between cancer types. These data indicate that TMB is associated with improved survival in patients receiving ICI across a wide variety of cancer types, but that there may not be one universal definition of high TMB.

Indocyanine green (ICG) is a well-established near-infrared dye which has been used clinically for several decades. Recently, it has been utilised for fluorescence-guided surgery in a range of solid cancer types, including sarcoma, with the aim of reducing the positive margin rate. The increased uptake and retention of ICG within tumours, compared with normal tissue, gives surgeons a visual reference to aid resection when viewed through a near-infrared camera.

Lysosome-dependent cell death (LDCD) is a regulated form of cell death initiated by increased lysosomal membrane permeability, leading to the cytoplasmic release of lysosomal enzymes and subsequent cellular damage. Molecular mechanisms controlling LDCD include lysosomal membrane instability and lysosomal enzyme release, which together lead to cell damage. A more profound comprehension of these underlying mechanisms may reveal new therapeutic targets for diseases associated with lysosomal dysfunction.

Objectives: Treatment delay can adversely affect cancer prognosis and public health. However, previous studies have not examined the association between cancer treatment delay and 5-year mortality risk for various cancer types in a single study population.
Methods: We used retrospective cohort data from 21 740 patients diagnosed with common cancers between 2000 and 2017, with mortality follow-up to 2022, from the Philippines' Department of Health-Rizal Cancer Registry to understand how treatment delay of <30, 30-90, or >90 days was associated with 5-year all-cause mortality risk, by cancer type and stage at diagnosis.

Post-translational modifications (PTMs) are chemical modifications that occur on specific amino acid residues after protein biosynthesis, which can affect protein function by altering protein structure, localization and activity, thus expanding protein diversity. Extensive research has demonstrated that PTMs can regulate various metabolic processes, such as glucose and lipid metabolism, as well as immune modulation in tumor cells, thereby promoting tumor initiation, progression, and metastasis. In this article, we systematically review a class of emerging PTMs whose roles in tumor metabolism and immune regulation have gradually been recognized in recent years, including six types: lactylation, palmitoylation, SUMOylation, succinylation, crotonylation, and myristoylation.
