A second look

I have arranged for a second opinion of my pathology slides, as I suspected the original diagnosis. The review was performed my Dr Michael Halliday, chief neuropathologist at the Toronto Hospital. He agrees with the initial diagnosis of GBM, with two conditions. Because the biopsy sample is so small, he cannot rule out the existence of oligodendroglial features that might have been missed in the biopsy sampling. Similarly he cannot rule out a low grade astrocytic component. My neuro-onc, Dr Warren Mason, tells me that either condition might explain my “remarkable response to treatment”.
