The present invention relates to: a temperature-sensitive hydrogel for cancer treatment; a photothermal composition comprising the hydrogel as an active ingredient; and a preparation method for the temperature-sensitive hydrogel for cancer treatment. The temperature-sensitive hydrogel of the present invention includes gold nanostars as active ingredients, and thus can generate heat by light irradiation, thereby exhibiting a photothermal therapy effect. In addition, the hydrogel temperature increases so that the release of nitric oxide (NO) from S-nitrosocysteine can be induced. In addition, the temperature-sensitive hydrogel of the present invention includes S-nitrosocysteine as an active ingredient so that, upon a temperature rise due to a photothermal reaction, the penetration of drugs into a tumor site can be improved by the release of NO, and at the same time, apoptosis of cancer cells can be directly caused; and includes an immunotherapy agent as an active ingredient so that tumor size can be effectively suppressed even with the passage of time. Therefore, as a material that enables complex treatment combined with photothermal therapy and immunotherapy, the temperature-sensitive hydrogel of the present invention having the aforementioned effect can be usefully utilized in the field of medicine for cancer treatment.

Provided are methods and compositions for enhancing radiotherapy in various cancers by administering dopamine receptor (DRD2)‐binding phenylpiperazine derivatives such as brexpiprazole, cariprazine, pipamperone, and perospirone. In vitro studies show that combining these agents with ionizing radiation (e.g., 5 Gy) significantly reduces cancer cell survival, suppresses metastatic and stemness markers (e.g., CD44, MMP‑2, Snail, Nanog), and promotes apoptosis. Fractionated or single‐fraction radiation regimens can be paired with DRD2 antagonists to lower treatment‐resistant phenotypes, decrease the likelihood of recurrence, and potentially reduce necessary radiation dosages. The approach applies to breast, prostate, lung, pancreatic, and brain cancers, among others. Depending on tumor characteristics, additional chemotherapeutic or immunotherapeutic agents may further improve outcomes.
