Patients with hepatocellular carcinoma (HCC) and liver metastasis (mets) present with a wide range of underlying liver dysfunctions and concomitant malignancies. Stereotactic body radiation therapy (SBRT) is well-tolerated and a valuable alternative for patients who are not eligible for invasive procedures. Yet, like all radiation therapy (RT) techniques, the energy dose deposit to tumor cells is limited by the surrounding healthy tissues. […]
Radiation oncology technological development is principally focused in improving the precision of radiotherapy (RT) and reducing unwanted irradiation to normal tissues. There is an unmet medical need into ameliorating the energy dose deposit within tumor cells without increasing the dose received by surrounding healthy tissues. […]
For patients (pts) with hepatocellular carcinoma (HCC) or liver metastasis (liver mets), stereotactic body radiation therapy (SBRT) is a well-tolerated option. Yet, the risk of injury to normal tissues limits the ability to efficiently sterilize tumor cells. Thus, hafnium oxide nanoparticles, NBXTR3, were developed, which increase the interaction of radiotherapy energy dose deposition within tumor cells when activated by an ionizing energy source like SBRT. […]
With recent advances in radiation delivery techniques, an increasing number of cancer patients undergo radiotherapy. However, due to the non-targeted nature of radiotherapy, doses are limited by potential toxicity to surrounding normal tissue. Thus, a major challenge remains to develop new strategies to improve the tumor selectivity of radiation therapy. […]
The enclosed abstract was presented at the 13th Journées cancéropole Grand Sud-Ouest at Poitiers. The abstract Hafnium oxide nanoparticles as an emergent promising treatment for solid tumors describes how hafnium oxide nanoparticles were designed at the nanoscale in the form of crystalline 50nm-particles to efficiently absorb ionizing radiation and increase the radiation dose deposited – “hot spots” of energy deposit – from within the tumor cells for efficient cell killing. […]
Elderly patients (pts) with head and neck squamous cell carcinoma (HNSCC) represent 25% of the affected population. They are not always eligible to the same treatment of younger pts, thus require new therapies. NBTXR3, injectable hafnium oxide nanoparticles activated by radiotherapy (RT), was developed to increase the local deposit of energy within the tumor. […]
Management of hepatocellular carcinoma (HCC) and liver metastasis (mets) requires complementary expertise of multiple specialties. Treatment decisions are increasingly complex and physicians must face a wide range of underlying liver dysfunctions and concomitant malignancies. Among available treatments, stereotactic body radiation therapy (SBRT) is well-tolerated. […]
