Singapore – A*STAR’s Institute of Bioengineering and Nanotechnology (IBN) has teamed up with the Singapore Institute of Advanced Medicine Holdings Pte Ltd (SIAMH) to explore how to better tackle nasopharyngeal carcinoma (NPC), a type of head and neck cancer, through targeted proton therapy.
The two parties are collaborating through an agreement to evaluate and optimise proton therapy for NPC with the use of patient-derived xenografts as well as in vitro 3D organoid models developed at A*STAR’s IBN, specifically for the treatment of recurrent and radioresistant NPC. The parties will also perform research on designing and establishing novel nano-radiotheranostic agents.
NPC that is detected early is often treated by radiotherapy, concurrently with chemotherapy. However, NPC presents a unique treatment challenge for radiation oncologists due to the proximity of cancer tissues to several critical organs and tissues such as the brain, the spinal cord, the salivary gland, and the optical nerves. Any damage to these adjacent structures could severely impair the quality of life of patients following the treatment.

Proton therapy could help solve some of these existing treatment challenges. It is a newer mode of radiation therapy that allows proton beams to more precisely irradiate the tumour compared to the x-rays used in conventional radiotherapy. This results in sparing damage to nearby healthy tissues and organs, and potentially less treatment-related side effects for patients to enjoy improved quality of life.
“We are excited to partner with SIAMH to explore ways of optimising proton therapy for treating NPC, through leveraging IBN’s expertise in developing tumour models and organoids for disease modelling and therapeutic optimisation,” said Dr. Lucky Sasidharan, Postdoctoral Fellow at A*STAR’s IBN.
“This collaboration offers a great opportunity to mutually apply our technologies and expertise in an innovative fashion for the benefit of cancer patients,” added Dr. Lim Chwee Ming, Adjunct Clinician Scientist at A*STAR’s IBN.

Dr. Djeng Shih Kien, Chairman and CEO of SIAMH said, “We are very happy to be able to collaborate with A*STAR’s IBN and develop a focus group interested in treating Asian cancers like NPC. Although NPC is rare in the Western world, it is common in Asia. There are 300 new cases a year in Singapore alone. It is the 3rd most common cancer in Malaysia, after colorectal and lung cancer.”
Dr. Djeng added: “Singapore is a small country with limited resources and talent pool. SIAMH’s first collaboration with IBN is our attempt to bring together leaders of IBN and the private sector in Singapore as well as domestic and international experts to maximise talent usage. Proton Therapy will be available in Singapore by early 2020. It would significantly reduce side effects due to its characteristic tumour targeting abilities which would be very advantageous in sparing critical structures in the case of NPC patients.”
Recently, the group also presented their work at the Australia and New Zealand Head and Neck Cancer Society’s Annual Scientific Meeting held at Adelaide[1][1].
NPC is the 9th most common cancer and 7th most frequent cause of cancer related deaths amongst males in Singapore.2 It is often associated with an Epstein-Barr virus (EBV) infection of the white blood cells and nasal lining at the back of the nose. One of the most common signs of newly-diagnosed NPC is the appearance of one or more lumps in the nose or on the neck.
