In our group of patients, no statistically significant difference was observed in the response to therapy depending on the patient's age (Fisher's exact test Response to radiotherapy concerning the patient's age, performance status, primary origin (histological type of tumor), and localization of the metastases that were irradiated.Also, no statistically significant difference was observed in the time to reach the maximum response according to any parameter: age of the patient (log‐rank test, Time to response in relation to the patient's age, performance status, primary origin (histological type of tumor), and localization of the metastases that were irradiated.In the entire group of patients, there was no statistically significant difference in the level of response to radiotherapy (degree of pain reduction based on VAS) according to all the mentioned parameters: age of the patient (Kruskal–Wallis test = 4.92, Level of response to radiotherapy in relation to the patient's age, performance status, primary origin (histological type of tumor), and localization of the metastases that were irradiated.Kruskal–Wallis test = 4.92
Kruskal–Wallis test = 0.17
Kruskal–Wallis test = 7.31
Abbreviations: Max, maximal reported pain according to visual analog scale; MIN, minimal reported pain according to visual analog scale; SD, standard deviation; SE, standard error.For each patient in our study, follow‐up lasted 3 months from the date of irradiation or until the date of death. In that interval, out of 64 patients in our group, 19 of them had a progression of pain. The average time until the progression of pain in the entire group of patients was 34 days (1–69 days), that is, the duration of the response was an average of 1 month after reaching the maximum response.In the entire group of patients, in the mean follow‐up time of 3 months, no statistically significant difference was observed in the time to pain progression after radiation depending on the patient's age (log‐rank test Pain progression in relation to the patient's age, performance status, histological type of tumor, and localization of the metastases that were irradiated.
