Combination therapy with the 5-FU patch and systemic chemotherapy. (a) Subcutaneous models were constructed using BXPC3-luc cells. Mice were subjected to combination treatment with the 5-FU patch and gemcitabine (50 mg/kg, IP injection, once per week). The effect of combination therapy was superior to that of single agent treatment (n = 4, *p < 0.05, **p < 0.01). (b) Survival rate of mice in various treatment groups. A tumour volume of 300 mm3 was defined as the ethical end point and the survival was presented. (n = 4) (c). No differences in body weight were observed between the four groups (***p > 0.05). (d) Tumour growth was monitored with the IVIS after tumour transplantation. The bioluminescence signal was lowest in the combination therapy group. (e) Images of hematoxylin and eosin (H&E)-stained cancer tissue sections from various treatment groups, along with Ki-67 and TUNEL staining (Tunel;green, DAPI;blue) for each condition.
