The Impact of Disease Progression on Health-Related Quality of Life Outcomes in Patients With Oligometastatic Disease at 12 Months Post Stereotactic Body Radiation Therapy.

Purpose: There is a paucity of published health-related quality of life (HRQOL) outcomes in patients with oligometastatic disease (OMD) who receive stereotactic body radiation therapy (SBRT) and no available data assessing the effect of disease progression post-SBRT on HRQOL in this patient population.

Methods And Materials: Patients with OMD who received SBRT in a phase II single-arm research ethics board approved study were included. HRQOL was a secondary outcome.

Evaluation of Bony Anatomy Versus Endobiliary Stents as Surrogates for Volumetric Image Guidance in Pancreatic Cancer.

Purpose: Online treatment setup verification through cone-beam computed tomography (CBCT) in pancreatic cancer patients is limited by low soft tissue contrast. This study aims to quantify the relative positional displacements between bony anatomy and endobiliary stents as surrogates for pancreatic cancers.

Methods: Under ethics approval, 258 localization CBCT images from 15 pancreatic patients with endobiliary stents were evaluated.

Inter-professional variability in the assignment and recording of acute toxicity grade using the RTOG system during prostate radiotherapy.

Background And Purpose: To compare the routine acute toxicity documentation practices of therapists and oncologists using the RTOG lower GI and GU scales.

Methods And Materials: Ninety consecutive prostate radiotherapy patients were identified. The weekly urinary and rectal acute toxicity grades routinely documented by therapists and oncologists were collected retrospectively from radiotherapy charts.
