The present study investigated the therapeutic potential of combining tumor-treating fields (TTF), a novel
cancer treatment modality that employs low-intensity, alternating electric fields, with 5-fluorouracil (5-FU), a standard chemotherapy drug used for treating pancreatic cancer. The HPAF-II and Mia-Paca II pancreatic cancer cell
lines were treated with TTF, 5-FU, or their combination. Combination treatment produced a significantly greater
inhibitory effect on cancer cell proliferation than each single modality. Furthermore, combination therapy induced a
substantially higher rate of pancreatic cancer cell apoptosis and exhibited a synergistic effect in clonogenic assays.
Additionally, combination treatment showed a greater inhibition of cancer cell migration and invasion than either
TTF or 5-FU alone. In conclusion, these findings suggest that the synergistic properties of TTF and 5-FU result in
greater therapeutic efficacy against pancreatic cancer cells than either modality alone and may improve survival
rates in patients with pancreatic cancer.
