The bone marrow is the soft, spongy part in the center of bones where blood cells are produced. It contains stem cells, which develop into the mature cells in our blood: red blood cells, white blood cells and platelets.
Bone marrow transplantation is a treatment option for some people who have life-threatening blood or immune system diseases. It can also be an option for the treatment of various other hereditary hematological disorders.
Bone marrow transplantation is the procedure where the damaged or destroyed bone marrow of a patient is replaced with healthy bone marrow stem cells from a bone marrow donor. After a successful transplantation the new stem cells take over blood cell production.
Ηistocompatibility of two individuals, or else the tissue similarity, is determined by the histocompatibility antigens, the Human Leukocyte Antigens(HLA). These antigens are inherited and are the molecular identity of our immune system. Due to the fact that they are highly variable, finding two individuals with the same tissue type is particularly difficult.
The search for a suitable donor for a patient begins among the patient’s siblings, who have 25% chance of compatibility, while within the extended family the chances are reduced. There are however many patients that cannot find a donor among their close family members, therefore a further search should be undertaken among unrelated volunteer donors who are able and willing to donate bone marrow to any patient in need.
A volunteer donor can be anyone between the ages of 18-45, in good health with no history of infectious diseases, tumors or heart disease. Registering as a volunteer donor is purely voluntary and altruistic and the donor has the right to change his or her mind at any time. Volunteer donors cannot be bribed nor burdened financially in any way.
The Foundation's policy is to not accept the registration of donors for a particular patient unless they are a parent or a sibling of that patient. This ensures the highest probability of finding a matching donor for each patient. It is also important that a volunteer bone marrow donor is willing to help any patient regardless of the race, ethnicity or religion of the patient.
In the event that a volunteer donor is found to be compatible with a patient, the donor will be called for further awareness and laboratory testing. In addition, they will go through a full medical examination before the collection process, to ensure the good condition of their health. After this procedure, the donor will be asked to decide whether to proceed with the collection process of the graft.
There are two ways that a bone marrow can be collected. The traditional way is when the bone marrow is collected under general anesthetic using a needle and syringe and the marrow is extracted from the pelvic bone cavity. The second method involves the administration of a medication for four days prior to the collection, and then the stem cells are collected by a procedure called leukapheresis.
Bone marrow donation is a surgical outpatient procedure that takes place at a hospital. The donor will receive anesthesia and feel no pain during the donation. Doctors use a needle to withdraw liquid marrow from the back of the donor’s pelvic bone. Through this procedure, about one litre of bone marrow and blood is removed, which represents 5% of the donor’s total quantity of bone marrow, and is naturally replaced within a few weeks.
This is a nonsurgical procedure that can take place at a blood center. For 4 days leading up to the donation, the donor will be given injections of a drug called filgrastim in order to increase the number of blood-forming cells in their bloodstream. Then the donor’s blood is removed through a needle in one arm and passed through a machine that separates out the blood-forming cells (leukapheresis procedure). The remaining blood is returned to the donor through the other arm. Blood-forming cells are back to their normal levels within a few weeks.
The expected risk of giving a graft is minimal. To avoid any serious complications each donor goes through a thorough medical examination before proceeding to transplant donation.
In the case of the traditional way of collecting a graft, the only symptom that is experienced by the donor is usually mild pain at the point of the puncture for a few days. In the case of collecting stem cells through the procedure of leukapheresis, the donor may have bone pain and some flu-like symptoms, which usually respond to medication given by the doctor. A day after the collection of the graft the donors can return back to their routine. In contrast to the minimal side effects of graft donation the donor is rewarded with the knowledge that they have given a patient a second chance to life.
It is rare to be asked to give a graft more than once. In some cases however, such as the relapse of the patient’s disease, a donor may be asked to give a graft for a second time. It is the donor’s decision to proceed to a second graft donation for the same patient. Karaiskakio Foundation prevents graft donation from a volunteer donor for more than one patient.
Nobody can force you to become a donor, but it is very important to think seriously and be informed before you join the bone marrow registry. Your withdrawal can cause great psychological distress to the patients and their families.
Throughout the process of donation and subsequently there will be full anonymity of both the donor and the patient. Cypriot law strictly prohibits the direct or indirect disclosure of the identity of the donor to the patient or of the patient to the donor. The Foundation only allows the exchange of a greeting card or a brief letter from the donor to the patient and vice versa, which has previously been checked by the Registry, to prevent the disclosure of any personal data.

The Karaiskakio Foundation has received funding under the Norwegian Financial Mechanism in the Programming Period 2009-2014, for upgrading part of its infrastructure, advancement of expertise on the subject, promotion of public awareness and enhancement the bone marrow donor registry in Cyprus. Aiming to improve public health and reduce health inequalities, through the proposed project, the Karaiskakio Foundation has enhanced its local health infrastructure with the establishment of a state-of-the art, specialised Childhood Cancer Diagnostic Laboratory which provides diagnostic support to the paediatric and other cancer patients.
The establishment of the Childhood Cancer Diagnostic Laboratory contributes towards:
• Technological progress in the diagnostic field and better understanding of cancer pathology, improvement of patient health and reduction of health inequalities
• Integrated and comprehensive analysis at the early stage of disease identification and classification, management, and treatment
• Structured, systematic and comprehensive laboratory support to patients, hence minimizing the time needed for diagnosis
• Opportunities to young scientists to excel in the field of cancer, invest in people through education
• Increase Social Awareness on cancer.
A parallel objective of the project is the enhancement of the Bone Marrow Donor Registry with new volunteer donors. The challenge is to find the means to attract and to cultivate the feeling of altruism in young adults, through modern means of communication (e.g., apps, social media, self-service stations, short videos etc).
The project further enhances the collaboration of the Greek Cypriot and the Turkish Cypriot Communities in Cyprus.
The Karaiskakio Foundation is already engaged in bi-communal collaboration through the Cyprus Bone Marrow Donor Registry, the greatest in significance and size bi-communal project since 1974. The Kemal Saracoglu Association (a Turkish Cypriot NGO) actively supports the Karaiskakio Foundation in contacting donors and serves as a contact point to help Turkish Cypriot patients and physicians to access the services of the Foundation. Furthermore, the Karaiskakio Foundation is providing both diagnostic and donor search services free of charge to all leukaemia and cancer patients from both the Greek and the Turkish Cypriot community.
