Around 1 in 5 people diagnosed with cancer in the UK take part in a clinical trial.
A trial looking at chemotherapy for advanced cancer of the bile duct or gallbladder (ABC 02)
This trial was looking at gemcitabine, with or without cisplatin, for people with advanced cancer of the bile duct or gallbladder. This trial was supported by Cancer Research UK..
Doctors thought chemotherapy may be useful for treating advanced cancer of the bile duct or gallbladder that could not be removed with surgery. But they were not sure which chemotherapy drugs were the best to use.
- Helped people to live longer
- Was better at controlling the cancer
- Caused fewer side effects
Summary of results
The researchers found that the combination of gemcitabine and cisplatin worked better than gemcitabine alone. And it didn’t cause any more side effects.
The trial recruited 410 people. Half the people had gemcitabine alone, half had gemcitabine and cisplatin.
Just over half the people taking part became more unwell during treatment. Some of this was due to the chemotherapy. This was the same for both groups. A few more people in the group having both drugs had a drop in the number of blood cells.
The average length of time before the cancer started growing again was
- 8 and a half months for people having both drugs
- 6 and a half months for people having gemcitabine alone
And the average length of time that people lived after treatment was also longer in the group having both drugs (11 months) than in the group having gemcitabine alone (8 months).
As the results showed that the combination of both drugs worked better, the researchers suggest this should become
