Efficacy of Chemotherapy in Pain Control of Patients with Cancer at the Early Phase of Their Disease

<b>Scope:</b> The rationale of the present study is to measure the impact of chemotherapy on the pain caused by the disease. <b>Materials and Methods:</b> The present study was based on the completion of two standardized questionnaires for the assessment of physical symptoms (Brief Pain Inventory-BPI-and the revised Edmonton Symptom Assessment System-ESASr) in three different moments. The research was conducted at the Oncology Institute "Prof. Dr. Ion Chiricuță" Cluj-Napoca between 2022 and 2023. <b>Results:</b> 24 patients were included in the study, and they received different cytostatic treatment regimens, adapted to the underlying pathology. We analyzed the distribution of all symptoms from the ESASr and the total score. In terms of the general situation, if we exclude pain, there is never a difference between Time 2 and 3. Furthermore, in all cases where there is a statistically significant effect, there is a difference between Time 1 and 3. We also analyzed the distribution of activities with which pain interacts in BPI. Regarding the general situation, three patterns of influence of pain on the examined parameters are found: for general activity, mood, ability to work, and sleep, there are significant differences between moments 1 and 2 and 1 and 3, without significant differences between moments 2 and 3. The second pattern identified refers to the lack of effect of pain on the ability to walk and on the relationship with other people. The peculiarity is represented by the influence on the enjoyment of life that was significantly improved only from Time 1 to 3. <b>Conclusions:</b> The present study demonstrated a considerable effect of cytostatic treatment on the management of cancer-related pain, as shown across different evaluations.
