"Use of deformable image registration techniques to estimate dose to or" by Marie Vozzo, Joel Poder et al.


Abstract
Purpose: The purpose of this investigation was to examine differences in estimates of accumulated rectal dose when using deformable image registration (DIR) compared with rigid image registration (RIR) methods, and parameter addition methods for combined transrectal ultrasound (TRUS)-based high-dose-rate brachytherapy (HDR-BT) and external beam radiation therapy (EBRT) treatments of prostate cancer. Material and methods: In this retrospective study, data from 10 patients who had previously received HDR-BT in one 15 Gy fraction, followed by 46 Gy EBRT in twenty-three fractions were used. To estimate total combined dose to the rectum, dose accumulation using both DIR and RIR methods were compared with parameter addition methods, which assume the same region of rectal anatomy receives the maximum dose from both treatment modalities. For both rigid and deformable image registration techniques, the quality of image registration was evaluated through metrics, including mean ....

Brachytherapy may proceed safely in cervical cancer patients following uterine perforation


Brachytherapy may proceed safely in cervical cancer patients following uterine perforation
A new study finds that brachytherapy, a common procedure that delivers radiation directly to cancer cells, may continue safely, potentially without delay or antibiotics, in cervical cancer patients following uterine perforation.
According to the World Health Organization, cervical cancer is the fourth most common cancer in women. Treatment for cervical cancer often involves brachytherapy combined with daily radiation therapy.
Brachytherapy delivers radiation directly to cancer cells through a tube placed within the uterus.
At times this tube can pierce the uterus and lead to a perforation. Many clinicians will not proceed with the treatment when a perforation occurs. This can lead to delays in therapy that may increase the recurrence risk and potentially lead to worse survival rates. ....

The IAEA concluded today a virtual educational session to help increase access to life-saving radiotherapy to support the treatment of cervical cancer in Morocco.
Cervical cancer is a major public health problem worldwide, with approximately 600,000 new cases diagnosed in 2020 and 340,000 deaths. It represents the second most frequent and fatal cancer among women in Morocco, especially since it is often diagnosed at an advanced stage. ....
