Hash Oil for Gliomas? What Would You Do?

A friend asked me to look at the evidence for hash oil as a treatment for glioma. His teenage daughter was recently diagnosed with brain cancer: a grade 3 anaplastic ependymoma. It recurred very rapidly after surgery and radiotherapy and the latest tissue diagnosis shows an aggressive grade IV glioma. Her prognosis is not good. No further attempts at curative therapy are indicated; the oncologist prescribed only palliative therapy with temozolomide. Her father, who had recently lost his wife to cancer (breast cancer metastatic to lungs and brain), was understandably devastated. As he puts it, he remains “focused on the belief that just maybe a cure can be found.” He stumbled on what he calls “earth-shattering news” regarding hash oil. He and his friends established a private wiki website which they are constantly updating with information about THC (tetrahydrocannabinol, the active ingredient in marijuana and hash) and other possible cancer cures: everything from curcumin to diet. He asked me to look at the information he has accumulated. He said

I hope to convince you in the same way I have done with my daughter’s GPs and her neuro-oncologist at BC Children’s Hospital.

The oncologist was not exactly convinced. He didn’t say he thought hash oil was likely to work; he only said it would be reasonable to try it as a complementary therapy. He said

the data published so far appears very preliminary, most of its potential effectiveness in vivo so far appears in colonic disease, having said that there doesn’t appear to be any obvious down side as a complementary therapy and may have synergistic effect, so may be reasonable as add on to temodal if she tolerates it

I wasn’t convinced either.

I will discuss two issues here:

  1. What does the evidence say about gliomas and hash oil?
  2. When is it reasonable to try an unproven treatment as a last resort?
