Megjegyzések:The overexpression of the pH regulator carbonic anhydrase IX (CAIX) due to hypoxic/metabolic stress was reported in various tumors as an adverse prognostic feature. Our retrospective study aimed to investigate the general pattern and dynamics of CAIX expression in rectal adenocar- cinoma following preoperative neoadjuvant therapy (NAT) in matched initial biopsy and surgical resection samples. A total of 40/55 (72.72%) of the post-treatment samples showed partial CAIX expression, frequently in the proximity of hypoxic tumor areas. CAIX expression showed a significant increase in post-treatment tumors (mean% 21.8 ? 24.9 SD vs. 39.4 ? 29.4 SD, p < 0.0001), that was not obvious in untreated tumors (mean% 15.0 ? 21.3 SD vs. 20 ? 23.02, p = 0.073). CAIXhigh phenotype was associated with mutant KRAS status and lack of pathological regression (WHO Tumor Regression Grade 4 and 5). However, the adverse effect of CAIX on overall or progression-free survival could not be statistically confirmed. In conclusion, the dynamic upregulation of CAIX expression is a general feature of rectal adenocarcinoma following neoadjuvant chemo-radiotherapy indicating therapy-induced metabolic reprogramming and cellular adaptation. A synergism of the CAIX-associated regulatory pathways and the mutant KRAS oncogenic signaling most likely contributes to therapy resistance and survival of residual cancer.
