Radiotherapy & Its Side Effects

AOC Interior

State-of-the-art Technology

In response to the high demand of radiotherapy and cancer-related in-patient hospital services, Hong Kong Integrated Oncology Centre (HKIOC) and Hong Kong Adventist Oncology Center (HKAOC) joined hands to form the Strategic Collaboration Party in 2016.

Referrals will be arranged for HKIOC patients who require radiotherapy, cancer-related in-patient or emergency hospital services at HKAOC.

HKAOC, housed at?Hong Kong Adventist Hospital?– Stubbs Road(HKAH – SR) and equipped with advanced facilities and state-of-the-art radiotherapy, provides a comfortable environment for patient treatment and comprehensive inpatient services.


TomoTherapy is an image-guided radiation therapy system which accurately locates tumours and adjusts doses of radiation accordingly, thus reducing radiation exposure to neighbouring tissues and organs. With an intensity-modulated radiation therapy (IMRT) technique, the device can deliver beams from 360 degrees, delivering radiation to multiple target areas of various sizes and shapes with precision. The built-in CT scan function captures images of tumours immediately before treatment sessions, which allows for a very precise targeting of tumours while ensuring the safeguarding of normal tissue.

4D image guidance: Avoids shifts of tumours due to breathing and other factors
6D patient positioning platform: Provides six degrees of positional correction, ensuring maximum accuracy
Agility? 160-leaf MLC: High resolution beam shaping for more effective modulation
Volumetric modulated arc therapy (VMAT): Radiation beams sweep in uninterrupted arcs around the patient, reducing exposure to surrounding healthy tissues while speeding treatment delivery

Y-90 Radioembolisation—New Treatment for Liver Cancer

Y-90 radioembolisation is a groundbreaking treatment for liver cancer, especially for liver tumours of later stages. This treatment can kill cancer cells precisely without affecting other functioning tissues or organs. The results are promising, with minimal side effects.

Traditional radiotherapy relied on the use of an external radiation source. This would often affect other tissues and organs in the abdomen, limiting the dose of radiation that may be used. The Y-90 treatment utilises the liver’s unique blood supply, delivering the largest radioactive material directly through the bloodstream to the liver tumor, maximising its effect.

Accurate and Efficacious

During the treatment, radioactive microspheres are carried through the catheter into the liver, targeting liver tumour cells. A number of clinical studies have shown that the Y-90 treatment can control tumour cells for 10 to 16 months, six months longer than the arterial chemoembolisation alone.

Efficient and Same Day Discharge

The operation time is only around one to two hours. Patients can return home on the same day, immediately after the operation.

Reduced Side Effects
