Radiation Therapy After Breast-Conserving Surgery

Given the high usage of radiation therapy (RT) for women ≥ 70 years of age with T1, estrogen receptor-positive (ER+) tumors undergoing breast-conserving therapy (BCT) despite data from randomized trials supporting omission of RT, researchers reviewed their institutional experience to determine if RT use is influenced by risk factors for local recurrence or comorbidities. They analyzed overall,…

Robots Can Detect Breast Cancer As Well As Radiologists

A new paper in the Journal of the National Cancer Institute suggests that artificial intelligence systems may be able to perform as accurately as radiologists in the evaluation of digital mammography in breast cancer screening. Breast cancer is the most common cancer in women, and despite important improvements in therapy, it is still a major cause…

Some Tumors Grow Back Aggressively After Radiation Chemotherapy

Many of the commonly used cancer treatments, such as radiation or chemotherapy, kill tumor cells. But sometimes, after those cells have died and been cleared away, a tumor will respond by growing faster and more aggressively. And scientists don’t know why. Using computer modeling techniques, researchers at Northeastern may have found the answer. Intentional damage…

Shedding Light Literally On Resistance To Radiation Therapy

A new Johns Hopkins study offers promise towards someday being able to non-invasively examine changes in cancerous tumors to determine whether they’ll respond to radiation treatment, before treatment even begins. Because The findings, published Feb. 28 in Cancer Research, can potentially help identify subsets of patients that are best suited for radiation treatment; thereby reducing…

Stereotactic Radiation Feasible For Oligometastatic Cancer

Stereotactic ablative radiation therapy (SABR) for recurrent oligometastatic cancer is a feasible and tolerable treatment option, according to a phase 2 study published in the January issue of the International Journal of Radiation Oncology, Biology, Physics. Overall survival Philip Sutera, from the University of Pittsburgh School of Medicine, and colleagues assessed the role of SABR for…

Sperm Quality Unaffected By Chemotherapy For Early Testicular Cancer

Men with early stage testicular cancer can safely receive one course of chemotherapy or radiotherapy after surgery without it having a long-term effect on their sperm count, according to a study published in the leading cancer journal Annals of  today. Although it is known already that several rounds of chemotherapy or high doses of radiotherapy given to men…

PET Scans Show Biomarkers Could Spare Breast Cancer Patients

In an effort to further individualize therapy and avoid over-treating patients, researchers at the Johns Hopkins Kimmel Cancer Center report a new study using PET scans has identified a biomarker that may accurately predict which patients with one type of HER2-positive breast cancer might best benefit from standalone HER2-targeted agents, without the need for standard…

Photoacoustic Imaging Measures The Temperature Of Deep Tissues

Measuring a fever is usually pretty simple place a thermometer under a patient’s tongue and get an accurate temperature reading within 30 seconds. But that simplicity does not translate when it comes to measuring the temperatures of specific tissues deep inside the body. Current techniques. Biomedical engineers at Duke University have demonstrated how photoacoustic imaging…

Study Finds Upsurge In 'Active Surveillance' For Low-Risk Prostate Cancer

Many men with low-risk prostate cancer who most likely previously would have undergone immediate surgery or radiation are now adopting a more conservative “active surveillance” strategy, according to an analysis of a new federal database by scientists from Dana-Farber Cancer Institute. Low-risk prostate The use of active surveillance increased from 14.5 % to 42.1 %…

Radiation Therapy Effective In Treating Men With Prostate Cancer

This type of radiation, known as stereotactic body radiotherapy, is a form of external beam radiation therapy and reduces the duration of treatment from 45 days to four to five days. because The approach has been in use since 2000; but has not yet widely adopting because; of concerns over how safe and effective this…

Radiologists Can Help Identify Victims Of Domestic Violence

Radiologists may play a crucial role in identifying signs of intimate partner violence, a type of domestic violence, according to a study published in the journal Radiology. Radiologists can identify potential violence-related patterns of injury and work closely with referring providers to provide care for the victims. intimate partner violence is a serious; preventable social and…
