Treatment for Cancer of the penis (penile cancer)
The type of treatment that you are given will depend on a number of things, including the position and size of the cancer, whether or not it has spread, the grade of the cancer, and your general health.
The treatments used for penile cancer include surgery, radiotherapy and chemotherapy. Surgical techniques have advanced recently, and it is usually possible to either preserve the penis or perform a reconstruction.
Men with cancer of the penis should be treated in a specialist cancer centre.
Surgery
If the cancer is affecting only the foreskin, it may be possible to treat it with circumcision alone.
All the above treatments can usually be given to you as an outpatient. They may be done under local or general anaesthetic, depending on individual circumstances.
Wide local excision If the cancer has spread over a wider area, you will need to have an operation known as a wide local excision. This means removing the cancer with a border of healthy tissue around it. This border of healthy tissue is important as it reduces the risk of the cancer coming back in the future. The operation is done under general anaesthetic and will involve a short stay in hospital.
Removing the penis (penectomy) This may be advised if the cancer is large and is covering a large area of the penis. Amputation may be partial (where part of the penis is removed) or total (removal of the whole penis). The operation most suitable for you depends on the position of the tumour. If the tumour is near the base of the penis, total amputation may be the only option.
The surgeon may also remove lymph nodes from the groin if there is evidence that cancer cells have spread to these nodes, or a possibility that they may have.
Reconstructive surgery It is often possible to have a penis reconstructed after amputation. This requires another operation. The techniques that may be used include taking skin and muscle from your arm, and using this to make a new penis. Sometimes it is also possible for surgeons to reconnect some of the nerves, to provide sensation and the necessary blood flow to allow the reconstructed penis to become erect. This type of surgery is carried out by surgeons who have specialist experience, and you may need to travel to a specialist hospital to have the surgery done.
Radiotherapy
External radiotherapy is normally given as a series of short daily treatments in the hospital's radiotherapy department. High-energy x-rays are directed from a machine at the area of the cancer. The treatments are usually given from Monday to Friday, with a rest at the weekend. Each treatment takes 10–15 minutes. The number of treatments will depend on the type and size of the cancer, but the whole course of treatment for early cancer will usually last for up to six weeks. Your doctor will discuss the treatment and possible side effects with you.
Before each session of radiotherapy, the radiographer will position you carefully on the couch and make sure that you are comfortable. During your treatment you will be left alone in the room, but you will be able to talk to the radiographer who will be watching you carefully from the next room.
Radiotherapy is not painful, but you do have to lie still for a few minutes while your treatment is being given. The treatment will not make you radioactive and it is perfectly safe for you to be with other people, including children, after your treatment.
Radioactive implants Radiotherapy can be given using a radioactive implant. This is also known as brachytherapy. Under a general anaesthetic, small radioactive wires are very carefully positioned in the affected area of the penis. The wires stay in place for about 4–5 days and are then removed. This method of treatment is usually used for smaller cancers on the end of the penis (the glans). While the implant is in place, you need to stay in an isolated room in the hospital so that other people are not exposed unnecessarily to the radiation.
Side effects of radiotherapy
There are sometimes side effects from radiotherapy treatment to the penis. Towards the end of your treatment, the skin on your penis can become sore and may break down. Long-term, radiotherapy can cause thickening and stiffening of healthy tissues (fibrosis). In some men, this can result in narrowing of the tube that carries urine through the penis (the urethra) and so can cause difficulty in passing urine. If narrowing of the urethra does develop, it can usually be relieved by an operation to stretch (dilate) the area. This is done by passing a tube into the urethra and is performed under a general anaesthetic.
Chemotherapy
is the use of anti-cancer (cytotoxic) drugs to destroy cancer cells. It can be one drug or several drugs used together. It is not commonly used to treat cancer of the penis. Chemotherapy cream may sometimes be used to treat very small, early cancers that are confined to the foreskin and end of the penis (glans).
Chemotherapy may also be given as tablets, or by injection, into a vein for more advanced cancer. It may be given along with surgery or radiotherapy (or both).
