Correlation of quality of life with self-care efficacy and social support in patients with nasopharyngeal carcinoma after radiotherapy / 中南大学学报(医学版)

To explore the correlation of quality of life with self-care efficacy and social support in patients with nasopharyngeal carcinoma after radiotherapy.
 Methods: A total of 179 patients with nasopharyngeal carcinoma at 3 months after radiotherapy were surveyed using self-designed general information questionnaire, European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 (EORTC QLQ-C30 V3.0), Chinese-version of Strategies Used by People to Promote Health (C-SUPPH), and Perceived Social Support Scale (PSSS).
 Results: The score of cognitive function was the highest, while the score of social function was the lowest. The score of related symptoms was 22.21±10.24, the overall score for quality of life was 52.46±17.96, the score of self-care efficacy was 62.14±14.50, and the score of social support was 56.03±7.63. Self-care efficacy of patients with nasopharyngeal cancer after radiotherapy was positively correlated with 5 functional areas of quality of life and overall quality of life, and negatively correlated with relevant symptoms (P<0.01). Social support was positively correlated with physical function, social function and overall quality of life (P<0.01), and negatively correlated with relevant symptoms (P<0.05). Multiple regression analysis showed that self-care efficacy could predict 5 functional areas of life quality, relevant symptoms, overall quality of life and social support predicted social function in quality of life.
 Conclusion: Self-care efficacy and social support for patients with nasopharyngeal cancer after radiotherapy can affect their quality of life. Nursing staff should pay attention to improving the self-care efficacy of patients, guide them to actively seek or obtain social support, and in turn to improve their quality of life.

Development and Validation of Dynamic Intensity Modulated Accurate Radiotherapy System KylinRay-IMRT / 中国医疗器械杂志

KylinRay-IMRT is the advanced radiotherapy treatment planning module of accurate radiotherapy system (KylinRay) aiming to provide accurate and efficient plan design platform. In this paper the system design, main functions and key technologies of KylinRay-IMRT were introduced. KylinRay-IMRT supports three dimensional conformal radiotherapy (3D-CRT), intensity modulated radiotherapy (IMRT) and many other types of treatment plan design with function modules including patient data management, image registration and fusion, image contouring, image three dimensional reconstruction and visualization, three dimensional conformal radiotherapy planning, intensity modulated radiotherapy planning, plan evaluation and comparison, and report print. KylinRay-IMRT has been tested by the national standard YY/T 0889-2013, the results showed that the performance of KylinRay-IMRT can fully meet the standard requirements.
