Last year in the UK over 60,000 cancer patients enrolled on clinical trials aimed at improving cancer treatments and making them available to all.
A trial comparing chemotherapy before and after surgery for women with advanced ovarian cancer (EORTC 55971)
This trial compared chemotherapy before surgery with chemotherapy after surgery for advanced ovarian, primary peritoneal or fallopian tube cancer.
This trial looked at two different ways of treating women with advanced ovarian cancer. One group had chemotherapy first, followed by an operation, then more chemotherapy. The other group had surgery first, followed by chemotherapy and if necessary more surgery.
The aim of this trial was to find out which order of treatment was better at stopping the cancer from coming back.
Summary of results
The trial team found that the women who had surgery first did no better than the women who had chemotherapy first.
718 women took part in this trial
- Half had surgery and 6 cycles of
- Half had 3 cycles of platinum chemotherapy followed by surgery and then 3 more cycles of platinum chemotherapy
The trial team analysed the results after monitoring the women in the trial for an average of just under 5 years. They looked at how long the women lived for after treatment. And how long before the cancer started to grow again. They found no difference between the 2 different groups.
We have based this summary on information from the team who ran the trial. The information they sent us has been reviewed by independent specialists (
