Filter by:The goal of this observational study is to learn how gonadotoxic treatments (chemotherapies, radiotherapies or immunotherapies) affect the fertility status of participants with cancer. The main questions it aims to answer are: - in females, if cancer therapies reduce the Anti-Müllerian hormone (AMH) concentration (ovarian reserve); - in males, if cancer therapies reduce sperm concentration (sperm quality).
Stereotactic Ablative Radiotherapy (SABR) is a modern RT technique that delivers high doses of radiation to small tumor targets using highly conformal techniques, while trying to avoid healthy tissues and organs. However, SABR treatment requires increased planning, treatment time, cost and potential for higher toxicity due to the higher dose. The purpose of this study is to compare single fraction (SF) SABR vs. multiple fraction (MF) SABR in regards to toxicities, progression-free survival, quality of life (QoL), and cost-effectiveness. In a subset of patients, we will also compare patient QoL, hospitalization rates, and cost-effectiveness between patients who complete QoL questionnaires, record symptoms and receive healthcare provider-guided intervention vs. patients who complete QoL questionnaires only.
The primary purpose of this study is to explore the association of high sensitivity C-reactive protein (hsCRP) and radiotherapy(RT)-induced toxicity in patients with nasopharyngeal carcinoma. In each patient, hsCRP levels in the pre- and post-RT plasma samples will be measured according to the schedule we set.
