Conclusions: The extent of resection and tumor invasiveness are related to the post-operative recurrence of AM. To improve the surgical procedures to maximize the tumor resection is usually important to improve the prognosis of AM patients. 0.05 was considered statistically significant. Results Clinical Characteristics of Patients in the AM Group and BM Group In the AM group, there were 19 females and 11 males, and the mean age was 58.6 16.6 years (range: 20C81 years); 46.7% (14/30) of patients were younger than 60 years. In the BM group, there were 26 females and 4 males, and the mean age was 53.6 14.6 years (range: 5C74 years); 63.3% of patients were younger than 60 years (Table 1). Significant difference was observed in the HESX1 gender between AM group and BM group, but there was no marked difference in 5(6)-Carboxyfluorescein the age. The skull base, convexity, and parasagittal meningiomas were found in 7, 17, and 6 patients, respectively, in the AM group, and 11, 13, and 6 patients, respectively, in the BM group, showing no pronounced difference between two groups in the tumor localization. The 5(6)-Carboxyfluorescein mean tumor diameter was 5.4 1.7 cm (range: 1.5C10 cm) in the AM group and 4.4 2.0 cm (range: 1.1C11 cm), there was marked difference in the tumor size between them, and more patients in the AM group had the tumor larger than 5 cm in the diameter.

In the AM group, seven patients received post-operative radiotherapy, of whom five underwent gamma knife medical procedures and two received whole brain radiotherapy. In the BM group, three patients received post-operative radiotherapy (all with gamma knife surgery). Patients in both groups did not receive post-operative chemotherapy. There was no marked difference in the proportion of patients receiving post-operative radiotherapy although it in the AM group was slightly higher than in the BM group ( 0.05). Findings From Follow Up In the AM group, 30 patients received complete follow up for any median of 34 months (range: 3C69 months), 12 developed recurrence and two died. In the BM group, 30 patients received complete follow up for any median of 32.5 months (range: 18C80 months), two developed recurrence and none died. The recurrence rate in the AM group (40%; 12/30) was significantly higher than in the BM group (6.7%; 2/30) ( 0.05). Immunohistochemical Findings Fourteen and twenty-four patients had been positive to PR in the AM BM and group group, respectively, showing proclaimed difference between them ( 0.01). Positive E-Ca appearance was within 13 and 26 sufferers in the AM BM and group group, respectively, displaying dramatic difference ( 0.01). 13 and 27 sufferers had been positive to -catenin in the AM BM and group group, respectively, showing proclaimed difference ( 0.01). The Ki67 LI was 8 4.32% in the AM group and 2.83 1.77% in the BM group, and factor was noted in the Ki67 LI between them. Furthermore, Ki67 LI 5(6)-Carboxyfluorescein 8% was discovered 13 sufferers in the AM group, but only 1 individual in the BM group ( 0.01). Univariate Evaluation of Factors Linked to the Post-Operative Recurrence Outcomes showed age group, tumor size, tumor invasiveness, and level of resection were linked to the post-operative recurrence positively. The somewhat increased recurrence price in the sufferers getting post-operative radiotherapy appeared to be from the usage of sub-total resection in these sufferers. Furthermore, the recurrence price was also considerably different between sufferers with triple invasion and staying sufferers (Desk 2).
