The three simultaneous tumors of 2014 had mixed features: the G3 tumor with a single lymph node metastasis had both abundant extracellular mucin production and signet-ring cells (Figure 1, panel 1b), while the other two were more conventional gland-forming adenocarcinomas, yet extracellular mucins were also present in lesser quantities (Figure 1, panel 1c). This evidence concerns the gene MUC5AC and adenocarcinoma.
