Abstract
AIM OF THE STUDY: Radiotherapy (RT) is a radical therapeutic option for patients with oropharyngeal cancer (OPC). It induces an acute postradiation reaction that may cause significant pain. The aim of this study was to analyse pain occurrence and intensity, as well as type and effectiveness of analgesic treatment, in OPC patients undergoing RT or radiochemotherapy (RT-CT). MATERIAL AND METHODS: Retrospective data were obtained for 42 OPC patients at clinical stages I-IVA, treated with adjuvant RT or RT-CT or definite RT or RT-CcT at the Comprehensive Cancer Center in Bialystok, Poland. Pain intensity and type of analgesic treatment during the therapy were analysed and compared with the intensity of the radiation-induced acute reaction, assessed weekly according to the Dische score. RESULTS: Thirty-nine (92.9%) patients received analgesic treatment. Analgesic therapy was started in 27 (64.3%) patients with administration of non-steroidal anti-inflammatory drugs (NSAIDs) and/or paracetamol, in seven (16.7%) with mild opioids and in five (11.9%) with strong opioids. Strong opioids were used during therapy in 21 (50%) patients. Co-analgesics were administered to six patients. Breakthrough pain was observed in 10 (23.8%) patients. CONCLUSIONS: High incidence of pain during RT and RT-CT calls for increased awareness of the importance of pain monitoring and treatment during RT of OPC patients. The analgesic treatment had to be adjusted individually.
