Background And Purpose: We investigate discrepancies in the assessment of treatment-related symptoms in lung cancer between healthcare professionals and patients, and factors contributing to these discrepancies.
Materials And Methods: Data from 515 participants in the REQUITE study were analysed. Five symptoms (cough, dyspnoea, bronchopulmonary haemorrhage, chest wall pain, dysphagia) were evaluated both before and after radiotherapy.
Objectives: Deep inspiration breath-holds (DIBHs) reduce heart and lung toxicity during breast cancer radiotherapy. Consecutive DIBHs are stressful, time-consuming, and leads to position changes. To facilitate the introduction of pre-oxygenation using high-flow nasal oxygen (HFNO) and hyperventilation to prolong DIBHs (L-DIBHs), we examined the effect of hyperventilation time on the duration of L-DIBHs.

- IBDM for breast radiotherapy needs better spatial normalisation due to differences in treatment positioning and breast characteristics, prompting an optimization study.
- Data from 996 patients were analyzed using various deformable image registration methods to improve the accuracy of spatial normalisation during treatment.
- The B-spline algorithm with normalised mutual information was identified as the most effective method, with supine registrations achieving the highest accuracy, while arm positioning did not significantly affect outcomes.
Objectives: The study was undertaken to assess the association between certification and volume of breast centres on the one hand and survival on the other in patients with invasive breast cancer (IBC).
Methods: The study comprises a cohort of 46,035 patients diagnosed with IBC between 2014 and 2018, selected from the nation-wide Belgian Cancer Registry (BCR) database, which was linked with health insurance, hospital discharge and vital status data. Overall and relative survival probabilities were obtained with Kaplan-Meier method and an actuarial approach based on Ederer II, respectively.
