Response to Bad news Cesium

I find it amazing that the Cesium chloride was a failure but conventional radiation therapy with concurrent low-dose temozolomide was not a failure . The patient didn't improve and died with the conventional therapy and
the report didn't site the conventional treatment as a failure.
It also says that the Cesium chloride was expensive
I'll bet the radiation and chemo was ten times more costly. Here is the heart of the problem. The inexpensive Cesium is competing with the expensive conventional treatment and that's why they want to Kill the use of Cesium.
