Around 1 in 5 people diagnosed with cancer in the UK take part in a clinical trial.
A trial looking at surgery for cervical cancer (SHAPE)
This trial is comparing two different operations for cervical cancer. It is for women with early stage cervical cancer who have a low risk of their cancer coming back. This trial is supported by Cancer Research UK.
More about this trial
Doctors often recommend that some women with early stage cervical cancer have an operation called a hysterectomy. Women usually have a radical hysterectomy. This involves removal of
- The cervix
- The womb
- The upper vagina
- All the tissues holding your womb in place
lymph nodesaround the womb
This is a successful treatment for many women. But some women may have long term side effects such as leaking urine or passing urine more often. Or their sex life may be affected. For example, sexual intercourse may be uncomfortable or painful due to shortening of the vagina or vaginal dryness.
Researchers think that some women may do just as well if they have less extensive surgery. They may only need a simple hysterectomy, this involves the removal of
- The cervix
- The womb
- A small portion of the upper vagina
- The lymph nodes around the womb
A simple hysterectomy may have fewer side effects in the short and long term.
The aims of this trial are to
- Find out if a simple hysterectomy is as good as a radical hysterectomy in treating cervical cancer
- To compare the side effects and quality of life following each operation
Who can enter
You may be able to join this trial if any of the following types of cervical cancer
- Adenocarcinoma of the cervix
- Squamous cell cancer of the cervix
- Adenosquamous cell cancer of the cervix (a mixture of both adenocarcinoma and squamous cells)
As well as the above, all of the following must apply.
- You have early stage disease which has a low risk of coming back (stage 1A2 or stage 1B1 cervical cancer). If you have a stage 1B1 cervical cancer, your cancer must be less than 2cm in size
- You have been diagnosed as a result of having a biopsy, LLETZ (Large Local Excision of the Transformation Zone) or a cone biopsy and your diagnosis has been confirmed by an internal examination and an MRI scan of your pelvis (you may not have to have an MRI scan if you have stage 1A2 cancer and you have had a LLETZ or cone biopsy). You should also have had an X-ray or CT scan of your chest
- Your consultant has recommended that you have surgery to remove your cervical cancer
- You are at least 18 years old
You cannot join this trial if any of these apply. You
- Have had another type of cancer. You can still take part if you have had non melanoma skin cancer or carcinoma in situ of the cervix or
lymphomaand some other types of cancer as long as these have been successfully treated and you have had no signs of any cancer in the last 5 years. Your doctors can advise you about this
- Are pregnant or you still want to have children
- If your surgery to remove your cancer is more than 5 months after your diagnosis
- Are due to have (or have had) chemotherapy before your surgery
This is an international phase 3 trial. The researchers need 200 women to join from the UK.
It is a randomised trial. The women taking part are put into treatment groups by a computer. Neither you nor your doctor will be able to decide which group you are in.
- Women in one group have a simple hysterectomy and removal of pelvic lymph nodes
- Women in the other group have a radical hysterectomy and removal of pelvic lymph nodes. This is the standard treatment
During your operation you have your pelvic lymph nodes removed (pelvic lymph node dissection). This is to check that the cancer has not spread to the lymph nodes and so reduce the chances of it being able to spread beyond the cervix. You then have your hysterectomy.
Your doctor or nurse will explain your operation and recovery in detail. You stay in hospital for about 3 to 5 days. You recovery will depend how fit and well you are and on the type of operation you had. This may take about 3 to 6 weeks.
After your operation your doctor may discuss further treatment with you to reduce the risk of your cancer coming back. This may be chemotherapy or radiotherapy or a combination of the two. These are standard treatments for cervical cancer and are not being looked at as part of this trial.
The trial team will ask you to fill out 2 separate questionnaires before you start treatment and on 5 different occasions over the following 3 years. They will ask you questions about your health and how your diagnosis and treatment has affected your quality of life. This is called a quality of life study. You will also be asked to fill out a questionnaire about your sexual health and how your treatment has affected your ability to have sex. This questionnaire is optional, you don’t have to complete this if you don’t want to.
You will see the doctors and have some tests before you have your operation. The tests include
- Physical examination
- X-ray or CT scan of your chest
After your operation you go to hospital to have regular check ups. You see a doctor and you may have an X-ray or CT scan if they think this is necessary. Your first appointment is 1 month after your surgery, then
- Every 3 months for the 1st year
- Every 4 months in year 2
- Every 6 months in year 3
- Every year after that until the trial stops
Doctors think that the side effects associated with a simple hysterectomy may be less frequent and less severe than a radical hysterectomy. There is a small risk of the cervical cancer coming back after a hysterectomy. This risk may be slightly lower following a radical hysterectomy compared to a simple hysterectomy.
The risks of having an operation include
- Blood clots in the leg or the lung
You have pain relief immediately after your operation and while you are recovering. The doctors and nurses will monitor you closely for any side effects so that treatment can be given promptly if you need it.
After your operation you may have some short term difficulties with passing urine and opening your bowels. You may also experience some sexual problems, such pain or vaginal dryness. These problems are usually temporary although a small number of women may have these side effects in the long term.
Your surgeon will talk to you about the risk of other, rarer side effects.
