مستخلص: | Background: Tumor-Stroma Ratio (TSR) has been recognized as a valuable prognostic indicator in various solid tumors. This study aimed to examine the clinicopathological relevance of TSR in Merkel cell carcinoma (MCC) using artificial intelligence (AI)-based parameterization of the stromal landscape and validate TSR scores generated by our AI model versus human-assessed. Methods: 112 MCC cases with Whole Slide Images (WSIs) were collected from four different institutions. WSIs were first partitioned into 128x128-pixel "mini-patches" then classified by a novel framework, termed Pre-TumOr And STroma (Pre-TOAST) and TOAST, whose output equaled the probability of the mini-patch representing tumor cells rather than stroma. Hierarchical random samplings of 50 mini-patches per region were performed throughout 50 regions per slide. TSR and Tumor-Stromal Landscape (TSL) parameters were estimated by the maximum-likelihood algorithm. Results: Receiver Operating Characteristic (ROC) curves showed the areas under the curve (AUCs) of Pre-TOAST in discriminating classed of interest (COI) including tumor cells, collagenous stroma, and lymphocytes from non-classes of interest (non-COI) including hemorrhage, space, and necrosis were 1.00. AUCs of TOAST in differentiating tumor cells from related stroma were 0.93. MCC stroma was categorized into TSR-high (TSR≥50%) and TSR-low (TSR<50%) using both AI- and human pathology-based methods. AI-based TSR-high subgroup exhibited notably shorter Metastasis-Free Survival (MFS) with a statistical significance of p=0.029. Interestingly, pathologist-determined TSR subgroups lacked statistical significance in Recurrence-Free Survival (RFS), MFS, and Overall Survival (OS) (p>0.05). Density-based spatial clustering of applications with noise (DBSCAN) analysis identified two distinct Tumor-Stroma Landscape (TSL) clusters: TSL1 and TSL2. TSL2 showed significantly shorter RFS (p=0.045) and markedly reduced MFS (p<0.001) compared to TSL1. Conclusion: TSL classification appears to offer better prognostic discrimination than traditional TSR evaluation in MCC. TSL can be reliably calculated using an AI-based classification framework and predict various prognostic features of MCC. (Copyright © 2024. Published by Elsevier Inc.) |
