With regard to OS, we observed an association similar to that reported in gastric cancer (increased risk for higher CACNA-1H and CACNA-1I expression, reduced risk for higher CACNA-1G expression) in the adenocarcinoma subset when all patients were included, whereas significance was retained for CACNA-1H only in squamous-cell carcinoma. Here, CACNA1I is linked to adenocarcinoma.
