Case presentation 2: Metastatic prostate cancer.
In October 2019, a 64-year-old Mexican male patient with no relevant medical history attended a routine prostate examination and revealed abnormal prostate antigen values (> 1700 ng/ml). Urinary and semen bleeding occurred promptly, and was diagnosed with metastatic prostate cancer. In February 2020, the patient refused chemotherapy and chose a metabolic therapy that consisted for 2.5 months of daily intravenous administration of the glucose analog 2-deoxy-D-glucose (2DG). Additionally, the patient followed a ketogenic diet and 20 h intermittent fasting. During therapy, the patient not had significant side effects.
In March 2020, the patient started the oral CDS protocol adding 1 ml of the vehicle DMSO 70% to solution and CDS absorption enema protocol. In 2021, the patient added 5 g of clinoptilolite zeolite to the diet, during fasting and before each meal. In 2022, the patient balanced oral and enema therapy with the intravenous CDS protocol, which he administered monthly according to previously described doses. Currently, the patient is without deficits or alterations in the daily routine. The patient has normal prostate antigen values and maintains a periodic control, with a forty-four-month follow-up (Fig. 2).
