Optic pathway glioma (OPG) is a rare brain tumor affecting children, with no standard treatment strategy. This study described the sporadic OPG survival outcomes after surgical treatment and analyzed the role of imaging features and resection status in children receiving different adjuvant treatments. This retrospective study included 165 OPG patients whose clinical information were obtained from the hospital record system. Tumor volume and residual tumor volume were calculated by delineating the lesion area. Kaplan–Meier method and Cox proportional hazards model were conducted to analyze the independent prognosis factor. A total of 165 patients were included in this study. Respectively, the 5-year overall survival (OS) and progression-free survival (PFS) were 87.58% and 77.87%. Residual tumor size and first adjuvant treatment (AT) after surgery were both associated with PFS. In patients with small-size residual tumors, there was no significant difference in PFS between the AT treatment groups. Moreover, age, exophytic cystic components, leptomeningeal metastases, and AT were associated with OS. In patients with exophytic cystic components and those with leptomeningeal metastases, there was no significant difference in OS. Our results revealed that OPG patients could avoid or defer AT by maximized resection. Age ≤ 2 years was a disadvantageous factor for OS. Patients with exophytic cystic components were more likely to benefit from primary surgery, and CT or RT was not beneficial for these patients. Patients with leptomeningeal metastases had a poor prognosis regardless of the treatment they received. Future prospective clinical studies are needed to develop more effective treatment regimens.

Patients with neuromyelitis optica (NMO) often have an accompanying autoimmune disease, most commonly, but not limited to Sjögren's syndrome (SS). The aim of this study was to compare clinical and laboratory features between NMO patients with and without SS and to investigate the prognosis of NMO in patients with and without SS. Twenty-three NMO patients with SS and 42 NMO patients without SS were included. Clinical and laboratory profiles were compared, including annual relapse rate and time from onset of NMO to Expanded Disability Status Scale (EDSS) scores of 4.0 and 6.0. More NMO patients with SS than those without SS had anti-nuclear antibody, anti-SS-A/Ro and anti-SS-B/La antibodies (91.3 vs. 35.7%, p < 0.001, 87.0 vs. 2.3%, p < 0.001, and 34.8 vs. 0.0%, p < 0.001, respectively). Serum immunoglobulins (IgA, IgM and IgG) were markedly increased in NMO patients with SS in comparison with those without SS. Annual relapse rate and the time from disease onset to an EDSS score of 4.0 and 6.0 were not significantly different between the two groups. No differences between the two groups were found for the other parameters, including AQP-4 antibody status, length of spinal cord lesion and brain lesions. These results imply that NMO in SS more likely represents coexistence with SS rather than representing the result of direct central nervous system involvement in SS. Autoimmune response appears to be more intense in the NMO group with SS, but did not cause a more severe prognosis in comparison with the group without SS, indicating that we should pay attention to the potential benefit of the antinuclear antibodies in NMO.
