Radiosurgery advised for postpneumonectomy recurrent lung cancer

A large study of patients who developed contralateral lung cancer after having a pneumonectomy suggests that stereotactic radiation therapy is a curative option with minimal toxicity, even for high-risk patients with chronic obstructive pulmonary disease.

Study calculates radiation dose risk for infants in Belgian NICU

A Belgian study has shed additional light on the amount of radiation dose delivered to infants in neonatal intensive care units (NICUs). The research provides reference values for NICU radiation dose, and also offers guidance on collecting dose measurements and converting them into organ-dose values.

Internal mammary node biopsies needed for better RT planning

A large study of breast cancer patients reveals that only 5% of patients with cancer-positive internal mammary nodes who receive radiation therapy (RT) will die of breast cancer recurrence within five years. This survival rate is comparable to patients with positive axillary lymph nodes who receive radiation therapy.

Study reports link between breast toxicity and timing of rad therapy

The timing of treatment for breast cancer patients receiving external-beam radiation therapy (EBRT) following intraoperative radiation therapy (IORT) may be an important factor in preventing toxicity. Patients who receive EBRT sooner than five or six weeks after receiving IORT may have a higher risk of developing chronic late toxicity, according to a study by German researchers.

Single-session breast radiotherapy safe for pregnant women, study finds

Breast-conservation surgery becomes an option for pregnant women in their third trimester. For many of these women, radiation therapy can safely be postponed until after birth. But the option of breast-conserving surgery may become available to all pregnant women if electron-beam intraoperative radiation therapy (IORT) is used.

HF weekly radiation effective for elderly breast cancer patients

Results of a clinical study at the Institut Curie in Paris verify that patients with nonmetastatic breast cancer can achieve the same long-term outcomes with conservative surgery followed by weekly high-frequency (HF) radiotherapy as patients who receive conservative surgery followed by daily radiation therapy.

Swiss pediatric CT survey leads to national dose standards

When a child needs a CT exam of the head, chest, or abdomen in Switzerland, pediatricians and parents can be assured that the radiation dose exposure will be identical regardless of the hospital. The country's success in standardizing pediatric CT dose could provide a model for similar efforts under way in the U.S.

MRI used to diagnose complex lung infections in children

CT is the gold standard for lung imaging, particularly when a chest x-ray lacks the detail needed to make a diagnosis. But CT's far higher radiation dose -- equivalent to 200 chest radiographs -- has some pediatric radiologists looking for an alternative modality, especially for children with chronic lung conditions who may require many CT scans.
