Radiation Therapy News and Research RSS Feed - Radiation Therapy News and Research

Radiation therapy (also called radiotherapy, x-ray therapy, or irradiation) is the use of a certain type of energy (called ionizing radiation) to kill cancer cells and shrink tumors. Radiation therapy injures or destroys cells in the area being treated (the “target tissue”) by damaging their genetic material, making it impossible for these cells to continue to grow and divide. Although radiation damages both cancer cells and normal cells, most normal cells can recover from the effects of radiation and function properly. The goal of radiation therapy is to damage as many cancer cells as possible, while limiting harm to nearby healthy tissue.

Metabolic pathway that shows potential to slow aging may drive brain cancer

While a particular metabolic pathway shows potential to slow down the aging process, new research indicates a downside: That same pathway may drive brain cancer. [More]
Clonal hematopoiesis may help predict cancer patients at risk for fatal form of leukemia

Clonal hematopoiesis may help predict cancer patients at risk for fatal form of leukemia

Patients successfully treated for breast, colon and other cancers can go on to develop an often-fatal form of leukemia, sometimes years after completion of treatment, due to a genetic mutation leading to secondary malignancies known as therapy-related myeloid neoplasms (t-MNs). [More]
Researchers show how microRNAs play key role in tumor progression and response to radiation

Researchers show how microRNAs play key role in tumor progression and response to radiation

OHSU researcher Sudarshan Anand, Ph.D., has a contemporary analogy to describe microRNA: "I sometimes compare MicroRNA to tweets -- they're short, transient and constantly changing." [More]

Researchers identify simple, inexpensive tool for assessing prognosis of pediatric brain tumors

A multi-institutional group of researchers, led by investigators at Children's Hospital Los Angeles and the University of Michigan, have identified a simple and inexpensive tool for assessing the prognosis of pediatric brain tumors called ependymomas. [More]
New study identifies novel target for treatment of Graves' disease and other scarring eye conditions

New study identifies novel target for treatment of Graves' disease and other scarring eye conditions

A new class of therapies may be on the horizon for thyroid eye disease (TED) and other destructive scarring conditions. [More]
Second opinions may not reduce overtreatment in prostate cancer, study suggests

Second opinions may not reduce overtreatment in prostate cancer, study suggests

A new analysis indicates that many men with prostate cancer obtain second opinions from urologists before starting treatment, but surprisingly, second opinions are not associated with changes in treatment choice or improvements in perceived quality of prostate cancer care. [More]
FDA approves new combo treatment for patients with advanced sarcomas

FDA approves new combo treatment for patients with advanced sarcomas

There are approximately 15,000 sarcoma cases annually in the United States, comprising more than 60 types of soft tissue sarcomas and 20 types of bony sarcomas. [More]
World Cancer Congress: DITTA urges development of integrated care approaches in medical technology

World Cancer Congress: DITTA urges development of integrated care approaches in medical technology

In its session at the World Cancer Congress, DITTA, the Global Diagnostic Imaging, Healthcare IT and Radiation Therapy Trade Association explained how fragmentation within healthcare systems makes it difficult for them to effectively manage complex conditions such as cancer where the various dimensions of care - prevention, screening, diagnosis, treatment and palliation – are inseparable.

IDoR 2016 spotlights role of radiology in diagnosis and management of breast diseases

IDoR 2016 spotlights role of radiology in diagnosis and management of breast diseases

On Tuesday, Nov. 8, more than 140 medical societies worldwide will mark the International Day of Radiology, celebrating the thousands of lives saved by the many contributions of breast imagers and radiation oncologists. [More]
High out-of-pocket costs, rather than race/ethnicity, may impact adjuvant endocrine therapy adherence

High out-of-pocket costs, rather than race/ethnicity, may impact adjuvant endocrine therapy adherence

High out-of-pocket costs, rather than race or ethnicity, are responsible for disparities associated with adherence to adjuvant endocrine therapy, according to a new study from researchers at The University of Texas Health Science Center at Houston (UTHealth) School of Public Health. [More]
Penn study reveals new sights into how some intestinal cells can withstand chemotherapy and radiation

Penn study reveals new sights into how some intestinal cells can withstand chemotherapy and radiation

When treating cancer with chemotherapy and radiation, decisions about dose must walk a fine line between attacking cancerous cells and preserving healthy ones. [More]
Robot-assisted surgery at NYU Lutheran offers hope to women with endometrial cancer

Robot-assisted surgery at NYU Lutheran offers hope to women with endometrial cancer

Nandi Kumar Carpen, a 51-year-old wife, mother of two young girls, and a nurse at a major city hospital, noticed some "spotty" bleeding outside of her regular menstrual cycle. [More]
Targeting TASINs can be viable approach for preventing colon cancer, research reveals

Targeting TASINs can be viable approach for preventing colon cancer, research reveals

A small molecule called TASIN-1 can selectively kill cells with a mutation that is considered to be a precursor to colon cancer, while sparing related normal cells, UT Southwestern Medical Center cancer biologists have demonstrated. [More]
Yale researchers identify chemical inhibitor that limits growth of lung tumor cells

Yale researchers identify chemical inhibitor that limits growth of lung tumor cells

A recently published Yale study may offer a new solution to fighting lung cancer. [More]
Innovative combined therapy could effectively fight tumors

Innovative combined therapy could effectively fight tumors

Researchers wish to treat tumors more effectively in the future by combining radiation therapy and focused ultrasound. The joint project SONO-RAY began on October 1st, 2016. [More]
Researchers report high response rate with single drug in phase I/II trial of paediatric brain cancer

Researchers report high response rate with single drug in phase I/II trial of paediatric brain cancer

A high response rate with a single drug in a phase I/II trial of paediatric brain tumour has set the stage for combination therapy with higher response and lower toxicity, researchers reported at the ESMO 2016 Congress in Copenhagen. [More]
Increasing incidence of thyroid cancer in past three decades

Increasing incidence of thyroid cancer in past three decades

The incidence of thyroid cancer has tripled in the past three decades, yet the reason for this is not clear. [More]
C-11 choline PET and MRI help physicians map patterns of prostate cancer recurrence after surgery

C-11 choline PET and MRI help physicians map patterns of prostate cancer recurrence after surgery

A team of Mayo Clinic researchers has, for the first time, successfully mapped patterns of prostate cancer recurrence, following surgery. Using C-11 choline PET imaging and multiparametric MRI, researchers found an anatomically diverse pattern of recurrence, which may help optimize treatment of patients whose prostate cancer returns after surgery.

Researchers identify new strategy to selectively sensitize cancer cells to radiation therapy

Researchers identify new strategy to selectively sensitize cancer cells to radiation therapy

Many types of cancer become drug resistant, making them difficult to treat. Researchers with University of California San Diego School of Medicine and Moores Cancer Center have identified a strategy to selectively sensitize certain cancer cells to radiation therapy that may improve tumor control and reduce treatment-related side effects.
