What is “voxel by voxel” radiotherapy? How to reduce toxicity of radiation therapy in cancer treatment? What is radiotherapy precision targeting and dose modulation?

Molecular radio-sensitizers help to increase efficacy of cancer radiotherapy at lower doses. Proton beam therapy and tumor-targeting molecules work together in cancer treatment. Leading radiation oncology expert from Zurich discusses cancer radiotherapy advances.

Radiation therapy treatment options. Radiosurgery in cancer treatment is important. Proton beam therapy is widely used today. Advanced cancer treatment by targeted radiation therapy. Medical second opinion confirms radiotherapy cancer treatment plan. Medical second opinion helps to include best radiotherapy and combination cancer therapy into comprehensive personalized treatment plan. Best precision medicine radiation therapy treatment for advanced stage cancer with metastatic lesions. Get second opinion on advanced cancer diagnosis and be confident that your precision medicine treatment is the best. Video interview with top oncologist in radiation therapy treatment from Zurich, Switzerland. Radiation oncology treatment advances. Part 2. Dr. Stephan Bodis, MD Professor of Radiation Oncology, Zurich, Switzerland. Then from 1980 to 2000, it was the time of 3D radiotherapy. CT scan diagnostic imaging made huge progress. Step by step this was integrated into planning algorithm for radiation oncology. Then from 2000 on, probably to 2010, technology advance was focused on toxicity reduction. "Don't treat what you do not need to treat by radiotherapy”. This is a "voxel by voxel" radiotherapy time. The keywords here are intensity-modulated radiotherapy and image-guided radiotherapy. The surgeons had their advances in technology. Radiotherapy tries to focus the treatment. Radiation therapy gives ionizing radiotherapy only to the cancer target and not to surrounding tissues. Dr. Stephan Bodis, MD. Professor of Radiation Oncology, Zurich, Switzerland. From 2010 on is the modern era of radiotherapy. I think it's now the time for radiosurgery. Others call it stereotactic radiotherapy and the proton beam therapy to treat cancer. These technology concepts are promising but they are very demanding. I think they need an excellent interdisciplinary cooperation. In addition, cancer proton beam therapy is expensive. So this is the clinical path. In the clinics, I think I would like to stay brief that since 2000, probably all major adult solid cancer malignancies. At least one phase three clinical trial came out with a significant progress. This includes radiotherapy as one of the modalities. So interdisciplinary oncology makes huge progress. In the field of cancer biology, I think there were several issues. We have the advent of new cancer medications. Dr. Stephan Bodis, MD (Professor of Radiation Oncology, Zurich, Switzerland). It was not so clear 20 years if molecular biology will succeed as a discipline in the field of radiotherapy, radiation oncology. But now with hypo-fractionated radiotherapy, with proton beam therapy, with molecular radio-sensitizers, we need to know molecular biology. It is a third pillar of radiotherapy beside clinics and physics. I think cancer biology is a must. We made small progress but probably important to mention it briefly. It is a work flow. Work flow with technology, IT technology, computer technology, scheduling a patient, guiding through treatment is much easier than 20 or 30 years ago. The last thing is administrative issues. Tumor center certification. Organ center certification are probably a must for big cancer centers. There is a huge benefit for radiotherapy. Dr. Anton Titov, MD. Thank you very much. Thank you, this is very important progress. It's a very fast developing field. Cancer radiation therapy advances overview by top Swiss radiation oncologist. Targeted regional radiotherapy, proton beam therapy, radio-sensitization method.
