Childhood Cancer Awareness Month: Identifying early warning signs is critical

For many years childhood cancer has remained a taboo subject in our communities, mainly because too little was or is known about it. Many have known or come across an adult with cancer but for a child to be diagnosed with cancer is totally unheard of. No parent wants to hear the news that their ‘heartbeat in human form’ has fallen ill. One moment they are OK, the next, waves of emotions flood the parents. Mixed in all this are feelings of guilt, anxiety, uncertainty, constant wondering if they could have done anything differently. Most importantly the question, often unuttered remains “Is my child dying/ how much time do I have”.

Most young cancer patients live in developing countries

Childhood cancer is rare and involves only 1% of all cancers. It is reported that globally approximately 70% of all childhood cancer cases occur in low- and middle-income countries. If diagnosed early, approximately 70-80% of childhood cancers are curable in developed countries. Unfortunately, most children with cancer live in developing countries with limited resources and the cure rate does not reflect the same success. The low survival rates can be attributed to poor diagnosis coupled with too few specially trained doctors and nurses and the misbelief that child cancer is too difficult to cure. However, even in resource-poor environments at least 50% of childhood cancers can be cured.

Numerically, childhood cancer is not a significant cause of death in sub-Saharan African countries, which leaves childhood cancer less of a priority. In Africa, the most common paediatric health problems are malnutrition, infectious diseases such as HIV and tuberculosis. Whereas in Western countries, after accidents, cancer is the second leading cause of death in children and is a burden to the health system.

A study done by Stones et al in 2014 published the survival rates for children with cancer in South Africa at two different Units (Universitas and Tygerberg Hospitals) to be around 52%. The conclusion was that the children present late and with advanced-stage disease, which obviously affects their outcome. They also concluded that strategies to improve awareness of childhood cancer should be improved. Identifying early warning signs of childhood cancer is critical for parents and healthcare workers to ensure early diagnosis and improved cure rates. We often refer to these as red flag signs that should raise suspicion of the possibility of cancer as a diagnosis for the presenting patient.

Almost 85% of childhood cancers will present with the red flag signs, which could suggest the possibility of a childhood cancer, namely:

1. Pallor and purpura (bruising)

2. Bone and joint pain

3. Lymphadenopathy

4. Unexplained masses on any body part

5. Unexplained neurological signs

6. Changes in the orbit or eye

7. Persistent unexplained fever and weight loss

The most common cancer in children is leukaemia (blood cancer). Brain tumours are the most common non-haematological cancers, followed by nephroblastomas (kidney cancers) and neuroblastomas (sympathetic chain cells, the adrenal glands the most common site of origin).

We honour the children currently battling cancer and their families

Once there is clinical suspicion of cancer, the child should be investigated or referred for the relevant investigations to be conducted to get to the right diagnosis. Treatment for childhood cancer includes chemotherapy, surgery or radiotherapy. These may be given separately or in combination depending on the diagnosis. Many models of care exist, but regardless of the outcome, children and families who receive compassionate, holistic care of symptomatology and address their non-physical needs are able to face their illness with dignity and energy.

Childhood Cancer should not remain a taboo subject in South Africa and should be a topic of conversation more often so that people can be educated regarding the early warning signs and become more aware of its occurrence amongst children. Get the word out that a cure is possible. This month, which is known as Childhood Cancer Awareness Month, and throughout the year, we honour the children currently battling cancer, the families who love them, the clinicians and other caregivers treating them, the survivors of childhood cancer and the children who lost their lives to childhood cancer.

UFS involved in project to light up the townships

The parties involved with the project are from the left: Prof Hendrik Swart (Departmental Chairperson of the UFS Department of Physics), Dr Thembela Hillie (CSIR), Prof Neerich Revaprasadu (Department of Chemistry at the University of Zululand) and Dr Wynand Steyn (CSIR).

UFS involved in project that could light up the townships

The University of the Free State’s (UFS) Department of Physics is involved with a project that could make life easier in the townships through the use of artificial light.

“The project is based on the use of sunlight to activate nano material in for example cement and paint during the day. At night the cement or paint can then radiate light,” said Prof Hendrik Swart, Departmental Chairperson of the UFS Department of Physics.

According to Prof Swart an amount of R3,9 million has been made available by the Council for Scientific and Industrial Research (CSIR) for the further development of the project.

Prof Swart visited the University of Florida in America in 1995 for a year where he researched luminescent phosphor material that is suitable for flat panel television screens. The red, green and blue spots on the television screens originate from these kinds of phosphor materials. “At that stage plasma television screens were only a dream. Today it is sold everywhere,” said Prof Swart.

“Upon my return I started a research group at the UFS which investigated the degrading of phosphor material. We also started to concentrate on the effectiveness of nano phosphors. In the mean time our cooperation with the Americans was strengthened with follow-up visits to America of my colleagues, Prof Koos Terblans and Mr Martin Ntwaeaborwa,” said Prof Swart.

“Nano phosphors are basically luminescent powders that consist of particles that are 1 millionth of a millimetre. These particles can provide light as soon as they are illuminated with, for instance, sunlight. The amount of time these particles can provide light, is determined by the impurities in the material,” said Prof Swart.

According to Prof Swart nano particles are developed and linked to infrastructure materials in order for these materials to be excited during the day by sunlight and then it emits light during night time.

“The nano material is of such a nature that it can be mixed with materials, such as paint or cement. The yellow lines of roads can for example emit light in a natural way during night time,” said Prof Swart.

About a year ago Prof Swart and Dr Thembela Hillie, a former Ph D-student of the UFS Department of Physics, had discussions with Prof Neerich Revaprasadu from the University of Zululand and the CSIR about the possibility of mixing these nano phosphor particles with other materials that can be used as light sources in the building of roads and houses.

“Prof Revaprasadu is also actively involved in the research of nano materials. Our efforts resulted in the CSIR approving the further extension of the project,” said Prof Swart.

“The UFS and the University of Zululand are currently busy investigating ways to extend the light emitting time,” said Prof Swart.

“There are eight M Sc and Ph D-students from the UFS and about five students from the University of Zululand working on this research project. The Department of Physics at the Qwaqwa Campus of the UFS, with Francis Dejene as subject head, is also involved with the project,” said Prof Swart.

According to Prof Swart the further applications of nano materials are unlimited. “Children whose parents cannot afford electricity can for instance leave any object such as a lamp, that is covered with these phosphor particles, in the sun during the day and use it at night as a light for study purposes,” said Prof Swart.

According to Prof Swart the further extension of the project will take about two years. “During this time we want to determine how the effectiveness of the phosphors can be increased. Discussions with the government and other role players for the possible implementation of the project are also part of our planning,” said Prof Swart.
