ABSTRACT
OBJECTIVE To construct the drug clinical comprehensive evaluation index system and quantitative grading in China， and to provide a reference for scientifically carrying out comprehensive clinical evaluation of drugs. METHODS The analytic hierarchy model was used to establish the drug clinical comprehensive evaluation index system， the weight of the evaluation index and the quantitative grading of each index were determined through expert consultation and model calculation. RESULTS The results of expert consultation were integrated by using the analytic hierarchy model， and the drug clinical comprehensive evaluation index system was obtained： including six first-level indicators of effectiveness， safety， economy， suitability， accessibility and innovation， as well as twenty-three second-level indicators of recommended status， medication for special populations， and drug treatment costs； the weight of each indicator was calculated through estimation-matrix method. CONCLUSIONS The analytic hierarchy model can construct the drug clinical comprehensive evaluation index system and quantitative grading in China， which can provide methodological references for comprehensive analysis and decision-making， thus making the clinical comprehensive evaluation of drugs completer and more scientific.
ABSTRACT
Introduction: Gliomas are neoplasms with high recurrence and mortality. Due to the difficulty to apply the World Health Organization (2016) classification, developing countries continue to use histological evaluation to diagnose and classify these neoplasms. Objective: To develop a semi-quantitative scale to numerically grade gliomas by its morphological characteristics. Method: A cohort of patients with gliomas was assessed and followed for 36 months. Tumor tissue sections were analyzed and graded, including aspects such as cell line, cellularity, nuclear pleomorphism, mitosis, endothelial hyperplasia, hypoxic changes, apoptotic bodies, necrosis, hemorrhage and proliferation index. Results: 58 cases were analyzed. Low-grade gliomas median score was 12 points (9 and 13.5 for percentiles 25 and 75, respectively), whereas for high-grade gliomas it was 17 points (16 and 20.5 for percentiles 25 and 75, respectively) (p < 0.0001). Thirty-six-month survival of patients with low (13/17) and high grade gliomas (6/41) was also significantly different (p < 0.0001). Conclusions: The semi-quantitative morphological scale allows an objective evaluation of gliomas, with an adequate correlation between the score, tumor grade and survival time.
