The FACT-NP is a reliable and valid instrument for measuring QOL in patients with NPC.

This study aimed to explore the perceptions and experiences of swallowing difficulties in irradiated survivors of nasopharyngeal carcinoma (NPC). Qualitative semi-structured interviews were conducted with 60 post-irradiation NPC patients after they had answered a set of self-report questions. The interviews were transcribed verbatim for analysis. Results of the self-report data showed that in response to a global question 'Do you have any swallowing difficulties?' eight-five per cent of the respondents reported a certain degree of difficulty. The qualitative interview findings, however, suggested that this figure might have been underestimated. Patient interpretations of swallowing difficulties had excluded part of the symptoms. Some respondents who claimed to have no difficulty swallowing, in fact, were suffering from oral retention of food bolus, regurgitation of food or liquids through the nose, and/or even choking. The risk of aspiration was generally neglected. Informants' concerns focused more on the threat of cancer recurrence, thus paid less attention to the radiation-induced swallowing complication. Respondents did not possess sufficient knowledge to judge their swallowing abilities at a general level. This study suggests ways to enhance patient-provider communication and health education to improve patient knowledge.
