Objective: To develop gastric cancer patients suitable for our culture of Quality of Life, finished processing the EORTC QLQ-STO22 scale to form the corresponding Chinese version, in order to provide an effective measurement tool for the evaluation of the quality of life of patients with gastric cancer and clinical efficacy assessment. Method: According to the WHO definition of quality of life, theoretical concepts, reference to recognized on the basis of the review of the literature, learning psychology, sociology and other related knowledge and application of the universal scale of cancer, and stomach cancer-specific scale widely listen to the group of the issues, especially clinical oncologists and patients with various malignancies views and through qualitative interviews and to rate the importance of the method of combining to form a pre-survey scale, of the 448 patients with malignant tumors (including gastric cancer 43 cases) pre-survey. According to preliminary survey results, the coefficient of variation for general module, correlation coefficient method, cluster analysis and principal component analysis of four methods of screening, and only for the specific module variation coefficient method and correlation coefficient are two ways to filter . Entries retained after the screening last discussion to determine the entry of the official scale, and ultimately the formation of a formal quality of life of cancer patients Measurement Scale - the gastric Scale QLICP-ST system and quality of life was measured by the 86 patients with gastric cancer to this Scale reliability, validity and responsiveness evaluation. Meanwhile, the Chinese method of scale the formation of the Chinese version of the EORTC QLQ-STO22 through translation and back translation, cultural adaptation step, the same measuring quality of life of the 86 patients with gastric cancer, EORTC QLQ-STO22 to appraisal Chinese Edition reliability, validity and responsiveness. Results: (1) the development of five areas including physical function, psychological function, social function, common symptoms and side effects of specific types of cancer field, a total of 40 entries in measuring quality of life of cancer patients Scale system - the gastric scale QLICP- ST, where the first four fields of 33 entries the general module QLICP-of GM specific types of cancer field is composed of seven entries gastric cancer specific module. QLICP-ST scale in various areas and the total scale test-retest correlation coefficient greater than 0.90, the various areas and the total scale of the first and the second score mean comparison, there was no statistically significant difference; Cronbach coefficient α : various fields between 0.70 to 0.86, 0.90 common modules, the total scale of 0.91; split-half reliability: all areas of common module is between 0.73 to 0.92, 0.91, the total scale is 0.94. Factor analysis showed: 10 common factors extracted cumulative variance contribution rate of 67.32 percent, with varimax rotation after the results consistent with theoretical idea.
