Association Between the Cancer Diagnosis-to-Intervention Interval and Short-Term Analgesic Response Following Interventional Pain Treatment: A Retrospective Cohort Study

Background/Objectives: Cancer-related pain remains difficult to control in a substantial proportion of patients despite contemporary pharmacological treatment, and interventional procedures may provide additional analgesic benefit. However, the relationship between the timing of these procedures and analgesic response remains insufficiently characterized. This study investigated whether the interval between cancer diagnosis and interventional pain treatment was associated with short-term analgesic response.
