Trans Tasman Radiation Oncology Group is one of the largest cancer clinical trials groups in Australia and New Zealand.

Over three decades, the Trans Tasman Radiation Oncology Group (TROG) has facilitated more than 100 clinical trials that have helped improve the quality of life and treatment options for almost 15,000 volunteer cancer patients.

During that time, the prognosis of cancer patients has improved considerably. In the 1980s the cancer survival rate was less than 50 per cent. Today, for some cancers, the survival rate is as high as 90 per cent.

TROG Cancer Research is focused on radiation treatment, for the many types of cancers it can treat.

Radiation medicine is the overarching specialist branch of therapies used to treat and eliminate cancer using radiation. One of these key therapies is radiation therapy, also called radiotherapy.

Conducting clinical trials for many types of cancer

Our upcoming, current, and past clinical trials have investigated the effectiveness of radiation therapy in treating the following groups of cancers. Our members have also investigated the impact of radiation therapy on symptom management and palliative care.

Research that has an impact

The radiation medicine research team is multidisciplinary, working with TROG Cancer Research members, hospitals, universities, and trial coordinating centres to advance vital cancer research for the community.

Translational research is a key strength of Trans-Tasman Radiation Oncology Group (TROG). Initiatives that were once a part of research projects conducted in laboratories and clinics throughout Australasia are now incorporated into standard care in a clinical setting.

The TOPGEAR trial: shedding light on gastric cancer treatments

Sebastian's Story

For Sebastian, who was diagnosed with stomach cancer at the age of 38, taking part in a clinical trial to help determine the best treatment options not only helped him exhaust all avenues on his cancer journey, but was an opportunity to contribute to scientific knowledge that is helping other patients today.

Radiation Therapy Quality Assurance program

Patients who choose to be part of a cancer clinical trial can be assured that patient safety and radiation therapy protocol compliance is stringently monitored under the TROG Cancer Research Radiation Therapy Quality Assurance (RTQA) program.

As new technologies and techniques are incorporated into radiation therapy treatment, RTQA develops robust radiation therapy planning, delivery, and quality assurance guidelines that ensure compliance and trial quality.

We invite you to explore the cancer clinical trials projects and people leading the fight to cure all cancers with one treatment.
