How do you define and IR-CTV for cervical brachytherapy?
Do you use a trimmed 10 mm expansion on HR-CTV? Do you also include the entire initial extent of disease? How much does your IR-CTV coverage affect your desired dose distribution (if at all)?
Answer from: Radiation Oncologist at Community Practice
Since most outcome data based on HRCTV dose , I don't routinely contour or monitor dose to IRCTV for cervical cancerhttps://www.ncbi.nlm.nih.gov/pubmed/30605752
