Cancer and radio therapy5 answersRadiation therapy is an established modality in cancer treatment, either alone or in combination with other modalities such as surgery and chemotherapy. However, it is associated with side effects and treatment interruptions, leading to worse overall survival and poor quality of life for cancer patients. To improve radiotherapeutic performance and monitor tumor response, a new X-ray responsive radio-pharmaceutical molecule containing chemical radiosensitizers has been developed. This molecule enhances the radiotherapeutic effect by producing high levels of ROS and inhibiting DNA repair in cancer cells, while also allowing for real-time monitoring of ROS levels during treatment. In breast cancer treatment, there has been a shift towards a volume-based approach to minimize long-term toxicity to the heart and lung. Radiotherapy is also effective for relieving localized symptoms in advanced breast cancer and managing brain metastases. Radiation therapy, using various forms of energy, is a common treatment for nearly every type of cancer. Advances in technology have allowed for more precise and accurate tumor targeting, reducing damage to surrounding tissues. In triple negative breast cancer, radiation therapy combined with gold nanoparticles has shown promise in enhancing the response to immune checkpoint blockers, potentially improving clinical outcomes.
Can a biologyst fix a radio?5 answersA biologist can fix a radio, as demonstrated by Lazebnik in his article "Can a Biologist Fix a Radio? — or, What I Learned while Studying Apoptosis". Lazebnik explores the potential pitfalls of the reductionist approach used in biology by applying it to the problem of fixing a broken transistor radio. He suggests that biologists, with their limited knowledge of physics, may approach a radio as a black box and troubleshoot it by cataloguing its components and identifying malfunctioning parts. This contrarian view challenges the prevailing reductionist paradigm in biology, which focuses on describing the smallest components of biological systems. Lazebnik's article highlights the need for a formalized language to describe the complex regulation of biochemical processes in living cells.
What are the key milestones in the history of radio immunotherapy?5 answersRadioimmunotherapy has had several key milestones in its history. One of the earliest reports on radioimmunotherapy techniques was published in the 1980s, marking the beginning of this targeted molecular therapy. However, it took time for the concept of radiation therapy as an immune adjuvant to gain acceptance. The proposal of local radiation therapy as an immunogenic modality was initially met with skepticism and resistance from the scientific community. Over the years, research has shown that radiotherapy can induce an immune response and has the potential to generate anti-tumor T cells in patients lacking sufficient anti-tumor immunity. The combination of radiotherapy with immunotherapy, particularly immune checkpoint inhibitors, has been recognized as a synergistic approach to enhance anti-tumor responses. These findings have led to the redefinition of radiotherapy as a partner for cancer immunotherapy, highlighting its potential in combination therapy.
