1. What Lymphoseek is and what it is used for

This medicine is diagnostic use only. This means that it is used in breast cancer, melanoma or oral cavity cancers to help find out about your illness. It is not a treatment for your illness.

Before it is used, the powder in the vial which contains tilmanocept is mixed with a radioactive medicine called sodium pertechnetate (containing 99mTc) to make a substance called technetium (99mTc) tilmanocept.

Since technetium (99mTc) tilmanocept contains a small amount of radioactivity it can make parts of the body areas visible to doctors during tests to help them see if the cancer has spread to places called ‘lymph nodes’ that are found near tumours. The lymph nodes nearest the tumour are called ‘sentinel’ lymph nodes. These lymph nodes are where cancer cells are most likely to have spread. When Lymphoseek has found the sentinel lymph nodes, they can be removed and checked to see if there are any cancer cells present. Lymphoseek finds the lymph nodes and can be detected using a special camera or detector.

The use of Lymphoseek does involve exposure to small amounts of radioactivity. Your doctor and the nuclear medicine doctor have considered that the clinical benefit that you will obtain from the procedure with the radiopharmaceutical outweighs the risk due to radiation.

2. What you need to know before Lymphoseek is used

Do not use Lymphoseek:

If you are allergic to tilmanocept or any of the other ingredients of this medicine (listed in section 6) or to any of the ingredients of the radiolabelled pharmaceutical.

Warnings and precautions

Take special care with Lymphoseek:

  • if you are pregnant or believe you may be pregnant
  • if you are breast-feeding

Before administration of Lymphoseek you should:

Follow the instructions of your doctor or nuclear medicine doctor.

Children and adolescents

This medicine is not for use in children and adolescents under 18 years of age because it has not been studied in this age group.

Other medicines and Lymphoseek

Tell your nuclear medicine doctor if you are taking, have recently taken or might take any other medicines. This includes medicines obtained without a prescription and herbal medicines.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant, or are planning to have a baby, ask your nuclear medicine doctor for advice before you are given this medicine.

You must inform the nuclear medicine doctor before the administration of Lymphoseek if there is a possibility you might be pregnant, if you have missed your period, or if you are breast-feeding.

When in doubt, it is important to consult your nuclear medicine doctor who will supervise the procedure.

If you are pregnant, the nuclear medicine doctor will only administer this product during pregnancy if a benefit is expected which would outweigh the risks.

If you are breast-feeding, breast milk should be discarded for 24 hours after administration of Lymphoseek. Please ask your nuclear medicine doctor when you can resume breast-feeding.

Driving and using machines

It is considered unlikely that Lymphoseek will affect your ability to drive or to use machines. Your doctor and nuclear medicine doctor will tell you when it is safe to drive after your surgery.

Lymphoseek contains sodium:

This medicine contains less than 1 mmol sodium (23 mg) per dose. That means it is essentially ‘sodium-free’.

3. How to use Lymphoseek

This medicine is for hospital use only.

There are strict laws on the use, handling and disposal of radiopharmaceutical products. Lymphoseek will only be used in special controlled areas. This product will only be handled and given to you by people who are trained to use it safely. These persons will take special care for the safe use of this product and will keep you informed of their actions.

The nuclear medicine doctor supervising the procedure will decide the quantity of Lymphoseek to be used in your case. It will be the smallest quantity necessary to get the desired information.

The quantity to be administered usually recommended for an adult ranges from 18.5 to 74 MBq (megabecquerel, the unit used to express radioactivity).

The dose may be divided up into smaller amounts. This means that the doctor can make more than one injection in the area around the tumour.

Administration of Lymphoseek and conduct of the procedure

Lymphoseek is injected under the skin, under the nipple, or in or around the tumour. The place depends on the type of tumour.

Lymphoseek is given either the day before or on the day of your procedure.

Duration of the procedure

Your nuclear medicine doctor will inform you about the usual duration of the procedure.

The Nuclear Medicine doctor uses a special camera to find Lymphoseek. The surgeon uses the pictures taken to see where the sentinel lymph nodes are located. The surgeon will also use a machine that finds the 99mTc part of the medicine. The 99mTc shows the surgeon where the sentinel lymph nodes are located.

When the sentinel lymph node is found, the surgeon removes it. If there is more than one sentinel lymph node, they will remove these nodes as well. The sentinel lymph nodes are then checked to see if cancer cells have spread to them.

After adminstration of Lymphoseek, you should?

The nuclear medicine doctor will inform you if you need to take any special precautions after receiving this medicine. Contact your doctor if you have any questions.

If you have been given more Lymphoseek than you should

An overdose is unlikely because you will get a specially measured amount of Lymphoseek precisely controlled by the doctor supervising the procedure. However, in the case of an overdose, you will receive the appropriate treatment.

Should you have any further questions on the use of Lymphoseek, please ask the nuclear medicine doctor who supervises the procedure.

  • high levels of calcium in the blood

This radiopharmaceutical will deliver low amounts of ionising radiation associated with the least risk of cancer and hereditary abnormalities.

If you get any side effects, talk to your nuclear medicine doctor. This includes any possible side effects not listed in this leaflet.

Reporting of side effects

If you get any side effects, talk to your doctor or nurse. This includes any possible side effects not listed in this leaflet. You can also report side effects directly ( see details below ).
