Cancer after kidney transplantation : prevent and diagnose

Cancer after kidney transplantation: Ways to prevent and diagnose

One of the main treatment methods for kidney failure is kidney transplantation.

This procedure will bring many benefits and convenience for kidney patients compared to other treatments, i.e. dialysis. This topic has been discussed in more detail in the article “What are the benefits and risks of kidney transplant?".

However, kidney transplants may also carry risks that demand certain medical examinations and considerations: for example, an increased risk of certain infections, diabetes, and some cancers.

We have already addressed in detail the likelihood of some infections and ways to prevent them in the article "Infection after Kidney Transplantation: Why it happens and How to prevent".

But exactly, what is the connection between the risk of cancer and kidney transplantation?

Why does the risk of cancer increase after a kidney transplant? Are different types of cancers equally common for kidney recipients or are some of them more likely? And how can these difficulties be prevented?

In this article, we will address these issues.

Why does the risk of cancer increase after a kidney transplant?

There are two main reasons for this:

- Use of immunosuppressive drugs

As we have reviewed in the article "What to expect: Kidney transplantation procedure step by step in Iran", one of the most essential steps after kidney transplantation is to receive immunosuppressive drugs regularly and for an indefinite time. These drugs are prescribed to prevent the immune system from rejecting the new organ. However, they can also have consequences.

Some of these drugs can make some cancers more likely than others. For example, antilymphocyte serum, or OKT3, are some of these drugs that can increase the risk of post-transplant lymphoproliferative disorder, or PTLDs, which is one of the most critical possible consequences of organ transplants.

But in general, it is the combination of these drugs that can cause some risks. The fact is that the human body occasionally and commonly develops some cellular abnormalities, but often the body's immune system is able to control and destroy them. When the immune system does not function properly due to medication, it is possible to lose control of such abnormalities and this would eventually lead to some cancers.

- Infections

Some viral infections may also increase the risk of some cancers. As mentioned, since the recipients of the organ have to take immunosuppressive drugs regularly, the incidence of some of these infections is likely to increase.

For example, the Epstein-Barr virus increases the risk of lymphoma, Human Herpes Virus-8 increases the risk of Kaposi sarcoma, and Human Papilloma Virus (HPV) can lead to skin cancer or cervical cancer.

Prevention and diagnosis

Some cancers are more likely to develop after a kidney transplant than others:

- Skin cancers i.e. melanoma

- Cancers related to the hematologic system or lymphoma

- Gastrointestinal cancers (i.e. colon, rectum, pancreas, etc.)

- Cervical cancer (in women)

- Breast Cancer

- Lung cancer

- Kidney cancer (either in the natal kidney or in the newly transplanted kidney)

However, the reality is that although kidney transplantation may have some consequences, it is almost the best treatment for kidney patients. Therefore, the solution is not to avoid this practice but to respect its later considerations, one of the most vital steps of which is cancer screening.

Many medical sources, including The American Society of Transplantation, have published guidelines for post-transplant cancer screening, some of which are reviewed below:

Skin Cancer:

People who have an organ transplant are three times more likely to develop skin cancer.

Therefore, it is necessary to use suitable and strong sunscreens (or sunblocks).

Skin cancers are usually diagnosed and treated early. The appearance of any unusual moles or spots after transplantation should be examined immediately. Also, the ability of this cancer to spread to other parts of the body is relatively low.

Among the prescription drugs, there is a possibility that an anti-rejection drug called sirolimus can also be used to prevent cancer. But in general, with the onset of skin cancer, many physicians reduce the dose of immunosuppressive drugs.

Lymphoma:

Lymphoma cancer or PTLD is a relatively more serious cancer that may be seen in a small number of organ recipients.

This disease leads to the growth of white blood cells in the immune system (mainly in the spleen and lymph nodes).

There are several treatments that would be different for each person. For some, it may be prescribed to stop taking immunosuppressive drugs, which may lead to rejection of the transplanted organ, for others chemotherapy or radiotherapy may be prescribed, and immunosuppressive drugs can be continued at lower doses.

Cervical (Neck of the Womb) Cancer:

Women after kidney transplantation may be more likely to develop this cancer than usual. Pap smears and cervical smears are recommended in these women.

This cancer can be diagnosed and treated in the very early stages with relevant tests.

Breast Cancer:

Kidney recipients should pay special attention to breast self-examination and regular clinical examinations after transplantation.

Research has shown that transplant patients usually develop non-cancerous breast masses, but even if these are not risky, it is vital that the treating physician examines any abnormalities.

Finally, it is necessary to reiterate that despite the potential risks mentioned, transplantation is still the preferred treatment for kidney patients, which will save them from endless dialysis and dying from kidney failure in the short term.

Therefore, it should not be left out because of these uncertain problems.
