Fever Therapy
Fever Therapy is recorded here as the cancer-care family of controlled heat and fever-range approaches: local hyperthermia, regional hyperthermia, whole-body or fever-range whole-body hyperthermia, thermal ablation, HIPEC-style heated perfusion, and older pyrogen/immunotherapy traditions such as Coley's toxins. It should be distinguished from unmanaged fever, infection, home sauna use, or overheating.
In conventional oncology language, hyperthermia exposes tissue to controlled high temperature to injure tumor cells directly or make them more sensitive to radiation and certain anticancer drugs. NCI describes local, regional, and whole-body approaches, including short periods of whole-body heating around 107-108 F in specialized settings. American Cancer Society likewise frames hyperthermia as a treatment usually combined with radiation or chemotherapy, requiring skilled temperature monitoring.
The fever-range branch focuses less on burning a tumor and more on physiologic heat stress, immune signaling, heat shock proteins, antigen presentation, innate/adaptive immune activation, blood-flow changes, and possible synergy with radiotherapy, chemotherapy, and immunotherapy. Modern reviews describe plausible cancer biology effects, but clinical evidence varies sharply by method, temperature, cancer site, device, and treatment combination.
The historical thread is important. William B. Coley observed tumor regressions after infections and developed bacterial toxin preparations intended to induce fever and immune activation. Later researchers and clinicians such as Ralf Kleef, E. Dieter Hager, Gian F. Baronzio, Robert Gorter, and whole-body hyperthermia groups continued to explore fever-range or thermal oncology concepts. The database should preserve that trail while separating historical claims, integrative-clinic claims, and regulated oncologic hyperthermia.
Evidence posture: local/regional hyperthermia and thermal ablation have recognized oncologic uses in selected settings, and hyperthermia may enhance radiation or chemotherapy. Whole-body and complementary/alternative hyperthermia claims are more mixed; a systematic review of complementary medical hyperthermia found heterogeneous studies and did not find reliable survival or quality-of-life evidence for alternative whole-body or electro-hyperthermia approaches. Safety matters: burns, pain, dehydration, nausea, diarrhea, cardiovascular stress, blood clots, and organ stress can occur, especially with regional or whole-body heating.
