Prof Jan du Plessis is the Head of the Paediatric Oncology Unit at the University of the Free State (UFS).

A post on Facebook by a bereaved parent of a young child who tragically died of cancer that reads: “I want my old life back, the one with my child in it”, is unfortunately still the sad reality that many families face, even though in developed countries the overall survival rate for childhood cancer is now over 80%. For some types of cancer and in developing countries such as South Africa, the rate is much lower. There are some childhood cancers for which there is no treatment and which are uniformly fatal. 

Another harsh reality, according to Prof Jan du Plessis, Head of the Paediatric Oncology Unit at the University of the Free State (UFS), is that some of those who do survive cancer can go on to suffer long-term (sometimes life-long) health issues as a result of their treatment. Almost all cancer treatments used in children today were actually developed for adults. Most of these treatments (such as chemotherapy or radiotherapy) target all fast-growing cells (not just cancer cells), and this leads to harsh side-effects in young, growing bodies. 

Prof du Plessis says the need for more effective and safer treatments for children is urgent. Despite better outcomes for children diagnosed with cancer, some do not survive. Currently, between 800 to a 1 000 South African children are diagnosed with cancer annually. However, it’s estimated that half of the children with cancer in South Africa are never diagnosed, according to the Cancer Association of South Africa (CANSA)

Different types of Childhood Cancer

Children can get many different types of cancer. Some of the most common childhood cancers are:
• Leukaemia – cancer of the blood and bone marrow, which is the most common childhood cancer.
• Brain cancer – cancer that grows in the brain which is the second most common childhood cancer. It kills more children than any other type of cancer.
• Neuroblastoma & Nephroblastoma – the most common solid tumours diagnosed in children under the age of five.
• Sarcoma – a cancer that grows in the bones and connective tissues of the body.
• Lymphoma – cancer that develops in the lymphatic system.

St Siluan Warning Signs of Childhood Cancer:

According to CHOC Childhood Cancer Foundation South Africa, research showed that an ongoing awareness campaign on the early warning signs was needed to improve the rate of referrals at an earlier stage of the disease. It is for this reason that 15 February (International Childhood Cancer Day), and the month of September, that marks Childhood Cancer Awareness Month, are important for awareness. 

“It is not possible to prevent cancer in children, but significant improvements can be made in their lives by detecting cancer early and avoiding delays in care. A correct diagnosis is important to treat children with cancer because each cancer involves a specific treatment regimen that may include surgery, radiotherapy, and chemotherapy.

“To improve early diagnosis we try to educate the public/students on the early warning signs of childhood cancer. We use the St Siluan Warning Signs for Childhood Cancer,” explains Prof Du Plessis. 

S – Seek medical help early for ongoing symptoms
I – White spot in the eye, new squint, sudden blindness or bulging eyeball
L – Lump on the stomach, pelvis, head, arms, legs, testicle or glands
U – Unexplained fever present for more than two weeks, weight loss, fatigue, pale appearance, easy bruising and bleeding
A – Aching bones, joints, back and easy fractures
N – Neurological signs, a change in walk, balance or speech, regression, continuous headaches with / without vomiting and enlarged head

According Prof du Plessis, his hope is to diagnose these kids early, the earlier they are diagnosed, the less treatment they are exposed. It is amazing to witness how the cancer kids adapt to their new normal and reality, says Prof Du Plessis. 

“They play soccer in the corridor, not in the park. One in fact learnt to walk in the hospital. Nurses and doctors become their new family. Their joy, strength and resilience is remarkable. Their laughter will make your heart melt. Your life will be forever changed, seeing a child fight cancer.”

Breeding of unique game requires a balance between conservation and sustainable use
2014-05-20

 

Game bred for qualities such as unconventional hair colour or horn quality, may on the long term have unexpected consequences for biodiversity and game farming.

This is according to the inaugural lecture of Prof Paul Grobler from the Department of Genetics at the University of the Free State (UFS).

Prof Grobler feels that the consequences of selective breeding should be examined carefully, as there is currently much speculation on the subject without sound scientific information to back it.

“At the moment, colour variation invokes much interest among game farmers and breeders. Unusual colour variants are already available in different game species. These unusual animals usually fetch much higher prices at auctions compared to prices for the ‘normal’ individuals of the species.”

Examples of these unusual variants are springbuck being bred in white, black or copper colours, the black-backed or ‘saddleback’ impala, and the gold-coloured and royal wildebeest.

A black-backed impala was recently sold for R5,7 million.

“Based on genetic theory, good reason exists why these practices need to be monitored, but one should also take care not to make the assumption that selective breeding will inevitably lead to problems,” warns Prof Grobler.

Grobler says that negative characteristics in a species can sometimes unwittingly be expressed during the selection process for a unique colour. “It is seen, for example, in purebred dogs where the breeding of a new race sometimes brings underlying genetic deviations in the species to the front.” He also believes that some of these animals may not be able to adapt to changing environmental conditions.

“However, one should also look at the positive side: because of the good demand for game, including unusual variants, there is much more game in South Africa today than in many decades. Balance should be found between the aims of conservation and the sustainable utilisation of game.”

Research at the UFS’s Department of Genetics is now trying to establish the genetic effects of intensive game breeding and predict the impact on biodiversity.
