Simple Summary Lung cancer is the leading cause of cancer related deaths and non-small cell lung cancer (NSCLC) is its most relevant subtype. Here, we present data on p53 co-playing 5 '-Nucleotidase Domain-Containing Protein 2 (NT5DC2) protein- and gene-expression and its clinical implication and prognostic value. NT5DC2 overexpression was associated with advanced lymphonodal spread and reduced survival in patients with adenocarcinoma of the lung. Moreover, dysregulated p53 in combination with overexpressed NT5DC2 might promote malignancy by interaction with cancer associated fibroblasts. Via immunohistochemistry (IHC) on tissue micro arrays (TMA) clinical and prognostic impact of p53 co-playing 5 '-Nucleotidase Domain-Containing Protein 2 (NT5DC2) protein expression was evaluated in 252 NSCLC patients. Confirmatory, gene expression database. mRNA levels of NT5DC2 were studied in 1925 NSCLC patients. High protein expression of NT5DC2 resulted in reduced median overall survival (OS) of patients with stage I-III adenocarcinoma (ADC) (Log Rank p = 0.026, HR 2.04 (1.08-3.87)), but not in squamous cell carcinoma (SCC) (p = 0.514, HR 0.87 (0.57-1.33)). Findings on OS were reproduced via gene expression analysis in ADC (p < 0.001, HR 1.64 (1.30-2.08)) and SCC (p = 0.217, HR 0.86 (0.68-1.09)). Yet, NT5DC2 mRNA levels were higher in SCC compared to ADC (p < 0.001) and in pN2 tumors compared to pN0/1 tumors (p = 0.001). Likewise, NT5DC2 protein expression associated with high-grade SCC. Moreover, NT5DC2 expression was positively correlated with p53 protein (p = 0.018) and TP53 gene expression (p < 0.001) and its survival effect was p53 dependent. While p53 expression was negatively associated with the presence of CD34+ cancer associated fibroblasts (CAFs), NT5DC2 expression insignificantly tended to higher levels of SMA+ CAFs (p = 0.065).
