This study suggests that administering chemotherapy prior to immunotherapy appears to improve OS in patients with advanced EC and GC, particularly when initiated as first-line treatment. These findings highlight the need for further research into biomarkers and personalized treatment strategies to enhance patient outcomes.

A prospective, non-randomized, two-cohort study was designed to evaluate the efficacy of sintilimab combined with chemotherapy in this setting...This preliminary analysis demonstrates that ICI combined with chemotherapy provides durable antitumor activity and a manageable safety profile as neoadjuvant and/or adjuvant therapy for locally advanced PSCC. These results warrant further validation in larger cohorts.

This study deciphered a novel druggable metabolic-epigenetic pathway (lactate-H3K18la-KIF20A-Myc-PD-L1) responsible for immune evasion in HCC. Targeting this axis might offer a promising strategy to reprogram the tumor microenvironment and restore immunotherapy sensitivity.

Consistently, single-cell analysis of colorectal tumors shows PUM1 positively correlates with PD-L1 and inversely with CD8+ T cell infiltration. Together, our study defines a novel IFN-γ-responsive post-transcriptional regulation that controls PD-L1 expression and tumor immune suppression.

Notably, CALB2 knockdown significantly sensitized CCA tumors to gemcitabine plus radiotherapy, an effect attenuated by KRT7 overexpression. These findings define a novel H3K4 methylation/CALB2/calcium/NF-κB/KRT7/PD-L1 signaling axis that drives immune suppression and therapy resistance in CCA, highlighting its potential as a multi-target strategy for combined immunotherapy and chemoradiotherapy.

Ferula assa-foetida shows potent anti-cancer effects against HCT-116 cells, with PD-L1 suppression suggesting immunotherapy synergy. Further in vivo and clinical studies are needed to confirm its therapeutic role in CRC.

Silencing SOX14 or DHHC9, or activating FXR, synergizes with anti-PD-1 therapy, reducing tumor growth in GCA-treated mice. These findings uncover a mechanism that GCA remodels the tumor microenvironment to mediate CRC resistance to immunotherapy, highlighting therapeutic opportunities targeting the FXR-PD-L1 axis in CRC patients with elevated serum GCA.

Opportunities abound for development of targeted therapies for management of ameloblastoma. Potential candidates are inhibitors of BRAF/MEK and smoothened (SMO) gene/HH pathways, interruption of the TGF-β-Cancer-associated fibroblast axis, anti-angiogenic strategies, immune checkpoint blockade, and RANKL-directed therapy.

ADCs are leading current clinical advances. Future priorities include biomarker-driven trial designs, strategic treatment sequencing, and innovative combination strategies to maximize therapeutic benefit while minimizing toxicity.

Additionally, new therapeutic interventions, such as microbiome-targeted therapies or probiotics, are suggested to enhance the efficacy of ICIs. By uniquely integrating clinical correlations with mechanistic insights on immune microenvironment, this may render pulmonary microbiota to be potential therapeutic strategies for future immunotherapy treatments.
