Methods: From August 1995 to September 2005, radical hysterectomy was chosen as primary treatment regimen for 122 patients (group A), 85 patients underwent radical hysterectomy after ef- fective neoadjuvant therapy (group B), and 98 patients received surgery after ineffective preoperative therapy (group C). All patients received postoperative therapy. Results: Atotal of 305 patients were analyzed. The maximum diameter of tumor was largest in group B, while the pathological risk factors (cervical infiltration, positive surgical margins) were in the lowest propor- tion. The 5-year mortality rate and relapse rate of group B were the highest, and the overall survival (OS) and progression-free survival (PFS) were the shortest (P 〈 0.05). No significant difference of long-term survival was found in group C and group A. No difference was found in the surgical of three groups. Large tumor more than 5.5 cm had higher effective ratio of treatment than those 5.5 cm or less. Patients received effective preoperative radiotherapy had better long-term prognosis than those received chemotherapy or radiochemotherapy. Conclusion: neoadjuvant treatment using for patients with IB2, IIA2 cervical cancer is effective in reducing risk factors of pathological, but it could not improve the long-term survival. The indications of adjuvant therapy after surgery should be reconsidered. Those tumors of diameter 5.5 cm or less response poor to neoadjuvant treatment, and no improvement of survival was found, so direct surgical treatment is suggested for these patients. Radiotherapy is a better choice of preoperative treatment.展开更多

However, little is known about CAATs adoption process by audit firms. Therefore, this paper adapts the technology readiness theory (TRI), the unified theory of acceptance and use of technology (UTAUT) and the technology-organization environment (TOE) framework and Denison organizational culture theory, and presents a new theory of unified technology readiness and cultural-technological-organizational-environmental model (UTR-CTOE), to explain CAATs adoption at both individual level and firm level. The methodology used in the study consists of a random sampling among the auditors through the administration of questionnaire. A total of 581 auditors registered with Mauritius Institute of Professional Accountants (MIPA) respond to the survey. Our main findings of this paper confirm that the relation between beliefs, such as perceived usefulness, perceived ease of use, facilitating condition and social influence, and motivation is positively correlated, while beliefs have a negative correlation with inhibition towards CAATs adoption. Results also indicate that firm's decision for CAATs adoption is positively influenced by cultural, technological, organizational, and environmental factors. Furthermore, there is an indirect impact of firm's internal and external influences on auditors' adoption of CAATs.展开更多
