My father had the ascorbate of potassium with ribosium once a day in the morning before having breakfast, 15 minutes before eating. Then he was given a lot of vitamins, a multivitaminic and nothing special beyond that. They always said what was important was the ascorbate of potassium with ribosium. In the first weeks we noticed the cancer stopped growing, then reduced his mass then started reducing faster then disappeared.
Doctors in hospital always asked him to try chemotherapy but he always refused and today he still takes the ascorbate of potassium with ribosium but not as frequently as before when he was sick.
