Abstract
Introduction Pancreatic adenocarcinoma (PDAC) is an aggressive tumor with limited response to both chemotherapy and immunotherapy. Pre-treatment tumor features within the tumor immune microenvironment (TiME) may influence treatment response. We hypothesized that the pre-treatment TiME composition differs between metastatic and primary lesions and would be associated with response to modified FOLFIRINOX (mFFX) or gemcitabine-based (Gem-based) therapy. Methods Using RNAseq data from a cohort of treatment-naïve, advanced PDAC patients in the COMPASS trial, differential gene expression analysis of key immunomodulatory genes in were analyzed based on multiple parameters including tumor site, response to mFFX, and response to Gem-based treatment. The relative proportions of immune cell infiltration were defined using CIBERSORTx and Dirichlet regression. Results 145 samples were included in the analysis; 83 received mFFX, 62 received Gem-based therapy. Metastatic liver samples had both increased macrophage (1.2 times more, p < 0.05) and increased eosinophil infiltration (1.4 times more, p < 0.05) compared to primary lesion samples. Further analysis of the specific macrophage phenotypes revealed an increased M2 macrophage fraction in the liver samples. The pre-treatment CD8 T-cell, dendritic cell, and neutrophil infiltration of metastatic samples were associated with therapy response to mFFX (p < 0.05), while mast cell infiltration was associated with response to Gem-based therapy (p < 0.05). Multiple immunoinhibitory genes such as ADORA2A, CSF1R, KDR/VEGFR2, LAG3, PDCD1LG2, and TGFB1 and immunostimulatory genes including C10orf54, CXCL12, and TNFSF14/LIGHT were significantly associated with worse survival in patients who received mFFX (p = 0.01). There were no immunomodulatory genes associated with survival in the Gem-based cohort. Discussion Our evidence implies that essential differences in the PDAC TiME exist between primary and metastatic tumors and an inflamed pretreatment TiME is associated with mFFX response. Defining components of the PDAC TiME that influence therapy response will provide opportunities for targeted therapeutic strategies that may need to be accounted for in designing personalized therapy to improve outcomes.

Optimal first-line treatment for platinum-eligible metastatic urothelial carcinoma: Comparison of chemo-immunotherapy, immunotherapy, and chemotherapy- A systematic review and meta-analysis. Clin Immunol 2022; 236:108927. [PMID: 35031491 DOI: 10.1016/j.clim.2022.108927] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2021] [Accepted: 01/09/2022] [Indexed: 11/20/2022]
Abstract
BACKGROUND The role of first-line of immunotherapy in metastatic urothelial carcinoma (mUC) remains unclear. This meta-analysis aimed to explore an optimal first-line treatment strategy for mUC patients. METHODS We carried out a meta-analysis between chemo-immunotherapy, immunotherapy, and chemotherapy in mUC based on randomized trials. The outcomes included overall survival (OS), progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), and treatment-related adverse events (AEs). A fixed-effect or random-effects model was adopted depending on between-study heterogeneity. RESULTS Three trials involving 3238 patients were included. PD-1/PD-L1 inhibitor plus platinum-based chemotherapy was associated with the improvements of OS (HR, 0.85; 95% CI 0.75-0.99), PFS (HR, 0.80; 95% CI 0.71-0.90) and ORR (OR, 1.32; 95% CI 1.07-1.63) when compared with platinum-based chemotherapy, but not with better DCR (OR, 1.07; 95% CI 0.78-1.46). PD-1/PD-L1 inhibitor alone was associated with worse ORR (OR, 0.38; 95% CI 0.17-0.87) and DCR (OR, 0.20; 95% CI 0.16-0.25) when compared with platinum-based chemotherapy while it did not statistically reduce the risk of mortality (HR 0.97 for entire cohort; 0.90 for PD-L1 high cohort). In safety analyses, the incidence of adverse events (AEs) between regimens showed no difference, but the frequency of AEs of grade 3 or severity was higher in chemo-immunotherapy compared to chemotherapy. CONCLUSIONS Compared with platinum-based chemotherapy, chemo-immunotherapy is associated with significantly improved PFS, OS, and ORR in the first-line therapy for mUC at the expanse of increased toxicity.
