Julian – Interview 33
Julian has prostate cancer. He is in a Phase 1 trial of a drug (a PARP inhibitor) which may stop cancer cells regrowing in people like him who have the BRCA2 genetic mutation. This mutation increases the risk of prostate and other cancers.
Members of Julian’s family carry the BRCA2 genetic mutation, which increases the risk of breast and ovarian cancer in women and prostate cancer in men. The mutation is more common in families of Eastern European Jewish origin. They first discovered this when one of Julian’s sisters had breast cancer and then ovarian cancer. Julian had a genetic test about six years ago which showed he carried the mutation, but at that point he was perfectly well. Then four years ago in 2004 he noticed blood in his urine and a biopsy showed he had prostate cancer. A bone scan showed the cancer had spread to his pelvic bone.
Because the cancer had already spread, he was told it was not worth having radical treatments such as surgery or radiotherapy. Instead, he was given a drug which blocks the production of hormones in the prostate which normally help cancer cells to survive. This worked for a while, and then he was given a different drug when the first one stopped working. When the second drug stopped working, Julian discussed further options with his consultant. He had read about a new drug (a PARP inhibitor) which it was hoped would stop cancer cells re-growing in people like him who have the BRCA2 genetic mutation. It turned out there was a Phase 1 trial of this drug at a nearby specialist hospital, to which Julian had been previously referred, and Julian asked to take part.
There were some concerns about whether he should take part. A Phase 1 trial is when a treatment is at an experimental stage, and researchers still need to find out what side effects there are, how severe they are, and what dosage is best. All participants take the new drug, unlike a Phase Three trial in which two or more different treatment are being compared and people are allocated randomly to receive one of them. As Julian still feels generally very well, the doctors wanted to be sure he understood the risk of possible unpleasant side effects and longer term damage, and could decide whether it was worth this risk. Julian himself felt that he wanted to take this chance of possible benefit to himself, and as someone who works in a cancer research institute there was also an element of scientific curiosity;. Given the risk to his own daughters if they have inherited the BRCA2 mutation, he also felt taking part in the research might help them directly in future.
So far he has been well on the drug, apart from a bit of nausea and stomach discomfort. He has been on the trial for about eighteen months, and it seems to have worked well for him. His level of PSA (prostate-specific antigen, a marker of how the cancer is changing) has gone steadily down and is now stable, and his bone tumours seem to be stable or reducing. He feels very lucky to have had this opportunity, and has been impressed by the quality of care at the specialist hospital. He hopes he will be able to help the research further by taking the drug long enough to see what the longer term risks are, if any.
