Background: Hepatocellular carcinoma (HCC) is the third leading cause of cancer deaths. Early-stage disease is treated with curative intent, but most patients present with advanced HCC, which carries a poor prognosis. Viscum album extracts (VAE) are used by cancer patients as an adjunct treatment or palliation.

Article Synopsis
- Researchers tested a slow-release emulsion of killed mycobacteria (CFA) for treating tumors in mice, dogs, horses, and human cancer patients, analyzing its effects on survival and immune response.
- * In preclinical trials, significant tumor regression and extended survival were observed across all species, with immune cell analysis indicating that early neutrophil infiltration predicted treatment success.
- * The treatment was well tolerated in human patients, and CT scans showed tumor regression, particularly in a late-stage renal cancer patient.
The following four observations point in the same direction, namely that there is an unleveraged potential for stimulating the innate immune system against cancer: (1) experimental treatments with bacterial extracts more than 100 years ago by Coley and contemporaries, (2) a positive correlation between spontaneous regressions and febrile infection, (3) epidemiological data suggesting an inverse correlation between a history of infection and the likelihood of developing cancer, and (4) our recent finding that a cocktail of pattern recognition receptor ligands (PRRLs) can eradicate solid tumors in cancer mice if applied metronomically. Because the main immunostimulating component of mistletoe extract (ME), mistletoe lectin, has been shown to be a PRRL as well, we suggest to apply ME in combination with additional PRRLs. Additional PRRLs can be found in approved drugs already on the market.

Case Report: Two patients with primary cutaneous B-cell lymphoma (pT2bcNxM0 follicle center and pT2ac-NxM0 marginal zone) either declined or postponed recommended conventional treatment and received high-dose, fever-inducing mistletoe treatment; a combination of intratumoral, subcutaneous, and intravenous application was given; and one patient also underwent whole-body hyperthermia.
