Auto-solidified tumor vaccine (ASTV) effectively combats cancer cells. This thermal-treated vaccine demonstrated significant efficacy in both animal models and human clinical trials for advanced liver cancer, improving survival rates.

Area of Science:

  • Immunology
  • Oncology
  • Biotechnology

Context:

  • Cancer cells can induce specific immune responses in the host.
  • Stimulating effective cellular immunity is crucial for cancer treatment.
  • Thermal treatment of tumors offers a method for immunotherapy development.

Purpose:

  • To evaluate the immune effect of Auto-solidified tumor vaccine (ASTV) on cancer cell inactivation.
  • To assess the efficacy of ASTV in preclinical (mice) and clinical (human) settings.
  • To investigate the mechanism of thermal biological effects on cancer immunity.

Summary:

  • ASTV, produced by heating tumor cells to 65°C for 5 minutes, showed a 93.3% success rate in protecting mice against H22 cancer cells.
  • Clinical application in 69 patients with inoperable advanced liver cancer resulted in a 76.8% efficiency rate and a 23% 5-year survival rate.

  • The study indicates that thermal biological effects inactivate cancer cells and alter host immunity, potentially leading to anti-cancer cellular immune responses.

    • Impact:

    • ASTV represents a promising immunotherapy approach for managing advanced cancers.
    • The findings highlight the potential of heat-treated tumor vaccines in cancer treatment strategies.
    • This research contributes to understanding tumor-induced immunity and developing novel cancer therapies.
