Dr Osayande Evbuomwan, Senior Lecturer and Medical Specialist in the Department of Nuclear Medicine at the University of the Free State (UFS), received the first clinical PhD in nuclear medicine completed at the UFS at the April graduation ceremonies.

Dr Osayande Evbuomwan, Senior Lecturer and Medical Specialist in the Department of Nuclear Medicine, Faculty of Health Sciences, at the University of the Free State (UFS), graduated with the first clinical PhD in nuclear medicine completed at the UFS.

He graduated on Thursday (18 April 2024) at the university’s autumn graduation ceremonies when the Faculty of Health Sciences conferred degrees on its graduation class of 2024.

Dr Evbuomwan, the man behind his department using Lutetium 177 PSMA (Lu-177 PSMA) therapy and now Actinium 225 PSMA therapy to treatment metastatic castrate resistant prostate cancer (MCRPC) – an advanced stage prostate cancer, said his PhD is about using a special radiopharmaceutical called Technetium 99m ECDG to detect active disease in the joints of patients with rheumatoid arthritis (RA).

More opportunities for similar degrees

This research has won him the Society of Nuclear Medicine and Molecular Imaging (SNMMI) International Best Abstract Award for South Africa during last year’s SNMMI 2023 Annual Meeting in the US.

“I am very grateful, and at the same time, proud about this achievement (his PhD). This qualification will definitely give more opportunities for further similar degrees at the department. So yes, I feel very happy and fulfilled.

“Rheumatoid arthritis is a debilitating disease with associated morbidity that can lead to serious joint deformity and destruction. The need for an investigation with a very high diagnostic accuracy in detecting active disease is needed, especially in the detection of subclinical disease. Few prior studies in the literature had shown promising results with Tc 99m ECDG imaging in this regard. So, we decided to conduct a proper prospective study to test this hypothesis,” says Dr Evbuomwan.

This research, he explains, was also aimed at finding out if the new nuclear medicine radiopharmaceutical for the identification of active disease in patients with rheumatoid arthritis can also offer prognostic information. This aspect of the study concluded that this particular radiopharmaceutical (Tc – 99m ECDG) is highly sensitive in identifying synovitis (inflammation of the membrane that protects joints) and is capable of offering prognostic information in patients with rheumatoid arthritis.

This was the first prospective study to assess the prognostic value of this radiopharmaceutical in patients with rheumatoid arthritis, Dr Evbuomwan says.

Researching theranostics in the future

According to him, he had a smooth journey to completing his PhD – something he contributes to support from the fantastic team of three supervisors, the assistant who prepared the radiopharmaceutical, the rheumatology department, the radiographers and nurses at the Department of Nuclear Medicine, and most importantly, his wife and two daughters.

His passion for research, growth and the practice of nuclear medicine were his major motivators on this journey.

Dr Evbuomwan is currently looking at the possibility of starting research on theranostics. The only stumbling block for now, he says, is that the department still does not have a PET/CT camera, as this is very vital in today’s nuclear medicine practice. However, together with the Free State Department of Health, they are working hard to secure one.

“I now want to focus on nuclear medicine therapy and its promotion. This includes both imaging and treatment (theranostics) of certain cancers, most especially prostate cancer, neuroendocrine neoplasms, thyroid cancers and the neuroectodermal tumours. I also want to focus on being involved with the training of more registrars at the department of nuclear medicine and increasing the awareness of nuclear medicine amongst colleagues in the Free State,” says Dr Evbuomwan about his future plans.

Last year, big sister led the Kovsie team, and now it is the turn of her little sister. Tanya Mostert will be filling the shoes of her big sister, Karla Mostert, when she leads the University of the Free State (UFS) team in the USSA tournament in Cape Town from Monday 4 July 2016.

Karla now helping as defence coach

Karla was captain in Johannesburg in 2015 when the UFS lost against Tuks in the USSA final by 39-48. The star of the Proteas is too old to play for the UFS again, and is now helping out as defence coach. Karla and Lauren-Lee Christians, who won’t be playing in the USSA tournament, were included in the South African Universities Netball team that will compete in the World Student Games in Miami, America, from 13 to 17 July 2016.

The Kovsie Netball team is one of seven UFS sports teams competing in USSA tournaments. The others are hockey (men and women), rugby, badminton, basketball, squash, and volleyball.

Mostert sisters are both natural leaders

Like Karla, Tanya is a natural leader. She was captain of the Zwartkop High School team, as well as the Free State U19 and U21 teams. “It is amazing that two children from the same home are both leaders, even if there is naturally a difference in their leadership style,” says Burta de Kock, the Kovsie coach.
“For me as coach, it is also wonderful to know that they (Karla and Maryka Holtzhausen, Protea captain and Kovsie assistant coach) are prepared to plough back at this young age. They are also role models for the other players.”
According to De Kock, she has a strong USSA group and wants the UFS to perform better than in 2015.

The UFS teams taking part in the USSA tournaments from Monday 4 July 2016 are:

  • Netball (Cape Town)
  • Hockey (men and women, Johannesburg)
  • Rugby (East London)
  • Badminton (Stellenbosch)
  • Basketball (Johannesburg)
  • Squash (Stellenbosch)
  • Volleyball (Pretoria)
