Chest wall toxicity reported after high-dose lung SBRT
Stereotactic body radiation therapy (SBRT) is emerging as an effective treatment for peripheral non-small cell lung cancer, but not without chest wall toxicity for some patients. Rib fractures and severe chest wall pain can occur months after treatment.

Parents sue California hospital over pediatric CT radiation overdose
A rural California hospital is being sued by parents of a child who underwent a CT exam during an emergency department visit for a neck injury. The parents allege that their 23-month-old boy received radiation burns and has permanent chromosomal damage due to excessive radiation exposure from the CT scan, which took over an hour to perform.

ED report turnaround times drop with speech recognition
Emergency department (ED) radiologists are crediting speech recognition technology with a dramatic reduction in report turnaround times at a level I trauma center. Final reports for "routine" procedures are being generated in an hour or less, compared to 3.6 days before implementation of a multiphase process improvement project.

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.

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.

Active thyroid surveillance effective, beneficial for older patients
Active surveillance with ultrasound and pathology is effective for patients with early-stage thyroid cancer, especially older ones.
A 58-year-old woman was diagnosed with ER-positive (Allred score 8) ILC in her right breast. Ultrasound and MRI found prominent lymph nodes in right axillary level I area, diagnosed as metastasis on ultrasound-guided fine-needle aspiration. F-18 FES-PET/CT showed a positive mass in right breast (white arrow; SUVmax, 5.6) and multiple F-18 FES–positive lymph nodes in right axillary level I, II, and II/III junction areas (red arrows; SUVmax, up to 12.2). In addition, a small F-18 FES-positive lymph node was observed in the right second internal mammary area (red circles; SUVmax, 1.8). However, biopsy could not be performed because it was too small and not visible on ultrasound; the clinician decided to include internal mammary lymph node in treatment field for adjuvant radiotherapy. The patient underwent lumpectomy with ALN dissection, with five metastases being identified in 13 lymph nodes dissected, and is scheduled to receive adjuvant chemotherapy, radiotherapy, and endocrine therapy.
