"I now know how cancer can strike anyone whatever their situation or circumstance. I hope by taking part in a trial it will help others in my position in the future.”
A trial looking at chemotherapy for male germ cell cancer (TE 23)
We know that this is an especially worrying time for people with cancer and their family and friends. We have separate information about coronavirus and cancer. Please read that information alongside this page. We will update that information as guidance changes.
This trial compared 2 different chemotherapy treatments for male germ cell cancers. This trial was supported by Cancer Research UK.
Germ cells are the cells that produce eggs in females and sperm in males. Male germ cell cancers usually develop in the testicles, but can be found in other parts of the body.
Doctors usually treat germ cell cancers with surgery if it is in the testicle, and also with chemotherapy if it is somewhere else in the body. They usually give a combination of chemotherapy called BEP.
BEP doesn’t always work well for germ cell cancers that are classed as having a ‘poor outlook’ (
The aims of this trial were to compare BEP with CBOP BEP to see which may cause the cancer to shrink more for poor prognosis male germ cell cancer and to find out more about the side effects.
Summary of results
The trial team found that CBOP BEP may be better than BEP for men with germ cell cancer who had a poor outlook (prognosis).
This was a randomised trial. The 89 men who took part were put into 1 of 2 groups.
- 46 men had BEP
- 43 men had CBOP BEP
The researchers looked at the number of men in each group who responded well to the chemotherapy. This was the number of men who had no sign of cancer (a
- 28 men who had BEP had a favourable response
- 32 men who had CBOP BEP had a favourable response
A year after treatment the researchers looked at the number of men who were alive and free of cancer. They found that
- 20 men who had BEP were
- 28 men who had CBOP BEP were
2 years after treatment 55 men were known to still be alive
- 27 men had BEP
- 28 men had CBOP BEP
The most common side effects of BEP and CBOP BEP were
- A drop in blood cells causing an increased risk of infection, bruising and bleeding
- Feeling or being sick
- Tiredness (fatigue)
These side effects tended to be more frequent with CBOP BEP.
The trial team concluded that CBOP BEP may be better at shrinking germ cell cancer, but a larger international trial is needed to find out how well it works to prevent cancer coming back.
