Frequently Asked Questions

Doctor: A clinical trial is a research project that aims to determine whether a new test or treatment works and is safe. These trials often originate in the laboratory and involve comparing two or more treatments in patients with a specific condition or those at risk of a condition. The goal is to generate high-quality evidence about which treatment or preventive strategy is more effective. Clinical trials are research studies involving people like you. Researchers conduct these trials to find new or better ways to prevent, detect, or treat health conditions.

Doctor: Radiotherapy uses high-energy radiation (like X-rays) to target cancer cells. The radiation damages the cancer cells, preventing them from growing. Doctors carefully aim the radiation at the tumour to minimize harm to healthy tissue. There are 2 main types of radiotherapy. External Beam Radiotherapy where beams come from outside the body like a focused flashlight. Internal Radiotherapy where radioactive material is placed inside the body near the tumour. Goals of radiotherapy are to completely cure cancer, boost effectiveness of chemo or surgery, after surgery to prevent cancer from coming back or ease symptoms when curing isn’t possible.

Doctor: Types of clinical trials include interventional trials and observational studies. Interventional Trials are like scientific experiments. People get split into groups, each receiving a different treatment. Researchers check for side effects and effectiveness. In observational studies researchers observe people without changing anything. No special treatments, just watching and learning.

Doctor: Clinical trials go through different steps. Phase 0 involves early tests in a few people. Phase I checks safety and dosage in a small group. Phase II studies effectiveness and side effects in a larger group. Phase III compares the new treatment to existing ones. Phase IV monitors the drug’s use after approval.

Doctor: A randomised controlled trial is like a scientific showdown to figure out which treatment works best. This includes ‘random allocation’ and ‘intention to treat analysis’. Random Allocation: Imagine researchers splitting people into different groups like sorting cards. Each group gets a different treatment—like a new drug or therapy. Intention to Treat Analysis: Even if someone doesn’t fully follow the treatment, they’re still part of the analysis. It’s like counting everyone who RSVP’d, even if they left early. Why all the fuss? Randomised controlled trials help us know if a treatment really works and if it’s safe. They’re like the gold standard in medical research!

Doctor: Imagine you’re playing a game of chance. You have two treatment options (A and B). Instead of someone deciding which treatment you get, we flip a fair coin. If it lands heads, you get treatment A; if it lands tails, you get treatment B. This way, it’s fair, and we can compare the treatments without bias.

Doctor: In the world of clinical trials, an arm refers to a group of patients who receive a specific treatment (or sometimes no treatment at all). Let’s break it down. Imagine a grand medical showdown with different treatments competing. Researchers randomly assign patients to various arms, each representing a different treatment. These arms allow us to compare outcomes, see which treatment works best. For example, one arm might receive an experimental drug, while another gets a placebo or an existing therapy. So, clinical trial arms are like different teams in a medical championship—they help us find winners!

Doctor: Informed consent means that researchers explain the purpose of the research to potential participants. They share details about what their role would be and how the trial will work. This includes details about the procedure, potential risks, benefits, and any alternatives. You then freely decide whether to participate based on this understanding.

Doctor: Standard of care in clinical trials refers to the usual treatment that patients receive for a specific condition outside of the trial. It’s like the “go-to” approach that doctors commonly use. When conducting a clinical trial, the control group (which doesn’t receive the experimental treatment) is often given this standard treatment rather than a placebo.

Doctor: When prostate cancer is first diagnosed, patients often undergo treatments such as surgery, radiation therapy, or other targeted therapies. Unfortunately, in some cases, the cancer can come back. This is known as recurrent prostate cancer. It means that despite the initial treatment, cancer cells have started growing again. While recurrent prostate cancer can be challenging, many patients continue to lead active lives.

Doctor: The treatment for prostate cancer can be surgery, radiotherapy, hormone therapy and/or chemotherapy. The POINTER-PC trial will treat participants whose prostate cancer has come back (also called recurrent prostate cancer) using two different types of radiotherapy. Radiotherapy is a cancer treatment that uses radiation to target and kill cancer cells. Beams of radiation are carefully directed at the cancer from outside the body using specialist equipment.
