Alex Villalta as he was working in his office for his tile business, got a doctor visit who told him that he had “lost a lot of weight.” He was diagnosed with a rare form of cancer called leiomyosarcoma that had spread to his liver and it weighed more than 4 kg. Dr Sinziana Dumitra, a MUHC Surgical Oncologist, recalls him saying,”Doctor, I will beat this, I will be here atleast 5 years from now.” “Even though that’s not what the data shows for metastatic leiomyosarcoma,” she argues. The doctors gave him 12-18 months to live but things got more complicated after surgery and chemotherapy. “Unfortunately, the disease was more widespread than expected.” She explains. They were to think outside the box for his case. This was when they decided to use a procedure that normally treats liver cancers called Y90 radioembolization.
It’s also known as Selective Internal Radiation Therapy (SIRT), often used for patients who are not a selected candidate for surgery/percutaneous ablation of liver tumours. The beads are coated with Y90 and delivered via arteries supplying these tumours. Y90 is a beta-emitting radionuclide. Y90 stands for Yttrium which is, yes, a radioactive substance. These beads are smaller than the size of a human hair.
Its mechanism does two things; one, it blocks internal arterial flow through the blood vessels cutting off blood supply and two, while it’s stuck in the blood vessels it gives off a high dose of radiation to the tumour. Note: that the beads are left in place during most of the radiation exposure which is within 10 to 14 days after the procedure and it starts to wear off 30 days after the procedure. These Y90 beads are also used to treat hepatocellular cancers or other cancers that are spread to the liver.
His grandkids are inspired by his motto to never give up in life. Oh, and he’s also cancer-free.
