Cancer Vaccines: A Promising Therapeutic Strategy in Advanced Solid Tumors

Recent advancements in understanding how cancer cells evade immune recognition have led to significant progress in cancer immunotherapy. Therapeutic cancer vaccines hold great promise due to their safety, specificity, and ability to establish lasting immune memory, serving as an effective immunotherapy either alone or in combination with other treatments in clinical research. Cancer vaccines aim to restore the host’s innate and adaptive anti-cancer immune responses by stimulating antigen-presenting processes and reversing the immunosuppressive environment that facilitates tumor immune evasion and metastasis. Although in clinical studies cancer vaccines have been observed to not effectively induce tumor regression, they can enhance local immune responses in combination with other immunotherapeutic agents, such as immune checkpoint inhibitors (ICIs), thus delaying cancer recurrence and prolonging overall survival in advanced tumor settings.
