Radiation Planning Assistant - A Web-based Tool to Support High-quality Radiotherapy in Clinics with Limited Resources
Published on: October 6, 2023
Summary
Researchers found that R848, a Toll-like receptor-7 (TLR7) agonist, effectively boosts anticancer immunity when combined with radiotherapy. This systemic immunostimulatory agent shows therapeutic promise for cancer treatment.
Area of Science:
- Immunology
- Oncology
- Radiotherapy
Background:
- Radiotherapy is a cornerstone of cancer treatment.
- Enhancing the immune system's response can improve radiotherapy efficacy.
- Toll-like receptor-7 (TLR7) agonists are known immunostimulatory agents.
Purpose of the Study:
- To evaluate the therapeutic efficacy of the TLR7 agonist R848.
- To determine if R848 can augment radiotherapy-induced anticancer immunity.
Main Methods:
- Administration of the TLR7 agonist R848.
- Combination therapy with radiotherapy.
- Assessment of anticancer immunity.
Main Results:
- R848 demonstrated convincing evidence of therapeutic efficacy.
- The agent successfully augmented radiotherapy-induced anticancer immunity.
Conclusions:
- R848 is a promising systemic immunostimulatory agent.
- Combining R848 with radiotherapy enhances anticancer immunity.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Cancer Therapies
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Radiation: Applications
The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.

Tumor Immunotherapy
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
