In vitro and in vivo experiments were respectively established using the unique mouse pancreatic cancer cell line (MPC- 83). Apoptosis and morphological changes of the MPC-83 were measured with flow cytometry and microscopy after heating to 42, 46, and 50℃ with water bath for 30 min. Four-week-old female Kunming mice were selected to establish subcutaneous pancreatic cancer model. The therapeutic effect (46℃ and 50℃) was evaluated by detecting various influences including pathological examination. Flow cytometry revealed the apoptosis and necrosis rate of MPC-83 were 46.13% (46℃) and 89.33% (50℃). Fourteen days after hyperthermia, the tumor growth rate were -0.64±0.73 and -0.72±0.79, which were significantly lower than that in each control group (P<0.05). Compared with control groups, tumor growth in the experimental group was markedly inhibited. Pathological examination showed that magnetic nanoparticles were distributed between tumor cells, and some of them were ingested by phagocytes. Fourteen days after hyperthermia, there were no subcutaneous nodules with only the MF remaining. In each control group, tumor cells grew very well, and hyperchromatic nuclei and pathological karyokinesis were seen simultaneously. MFH can reach perfect therapeutic temperature and heat tumor tissue specifically, inhibiting the growth of mouse pancreatic cancer and prolonging the survival time of the mice apparently. MFH has satisfactory therapeutic efficacy for mouse pancreatic cancer., authors=WANG Lufang¹, TANG Jintian², OUYANG Weiwei³, DONG Jian⁴, ZHAO Lingyun², WANG Xiaowen², HU Bing¹, authorsList=WANG Lufang, TANG Jintian, OUYANG Weiwei, DONG Jian, ZHAO Lingyun, WANG Xiaowen, HU Bing, authorCompany=1.
