Pasig hospital offers fresh hope to liver cancer patients

MANILA, Philippines – A new technology introduced recently in the Philippines offers new hope to Filipinos with liver cancer, including those whose chances of survival are considered slim.
Radioembolization involves the insertion of radioactive beads into specific cancerous areas in the liver to reduce or completely block blood flow to the tumor.
Dr. Ramon Santos-Ocampo, an interventional radiologist at the Medical City in Ortigas Extension is the only local doctor certified to perform the medical procedure.
The Pasig City-based hospital recently introduced the new technology to its patients.
Santos-Ocampo said the new procedure was documented to increase patient survival by about one and a half years more compared to other treatments.
The radiologist said radioembolization was not an experimental treatment but a mainstream intervention for patients with cancer of the liver.
He said the procedure was performed on patients who developed cancer of the liver either because of defects in the liver or from another cancerous organ.
Cancers in the colon and pancreas often spread to the liver first before moving to other parts of the body.
Santos-Ocampo said treatment options for liver cancer usually included organ transplant, surgery, or chemoembolization that involved the injection of a foreign substance into the tumor to stop blood flow to kill cancer cells.
But Santos-Ocampo said many patients in the country did not respond to these treatments. He hoped radioembolization would be beneficial to local patients.
Santos-Ocampo said the new treatment was best for Filipinos because of the high incidence of Hepatitis B in the country. Hepa B, he said, usually developed into cirrhosis or cancer of the liver.
He added that Filipinos would save a lot of money having the procedure done here instead of in the United States, Hong Kong or Singapore.
The procedure costs about P1 million at Medical City. In the US, the price tag is about $55,000 (about P2.4 million).
The procedure involves the insertion of about 20-60 million microbeads or the radioactive Yttrium 90 (Y90) spheres into the liver tumor through the artery in the groin.
The minute radiation beads conduct selective embolization (blocking of blood flow) to kill the tumor without causing significant radiation to the normal parts of the liver or even outside the patient’s body. The Y90 spheres come from Australia.
While the therapy is new in the country, Santos-Ocampo said it has been around for 10 years now.
In Sydney, he said, the procedure was so common it was considered an outpatient intervention procedure.
But Santos-Ocampo said timing might be perfect for the introduction of the treatment here.
In its present form, he said the new procedure had gone through “growing pains.”
On Wednesday, a 70-year-old woman with state 4 colorectal cancer that had spread to the liver underwent radioembolization at Medical City. She was discharged yesterday and there was very little disruption in her daily activities.
Santos-Ocampo performed the procedure under the supervision of Australian interventional radiologist Dr. Lourens Bester.
Earlier, a Filipino based in Canada underwent the procedure, he added.
