Abstract Purpose Diaschisis of cerebrocerebellar loops contributes to cognitive and motor deficits in pediatric cerebellar brain tumor survivors. We used a cerebellar white matter atlas and hypothesized that lesion symptom mapping may reveal the critical lesions of cerebellar tracts. Methods We examined 31 long-term survivors of pediatric posterior fossa tumors (13 pilocytic astrocytoma, 18 medulloblastoma). Patients underwent neuronal imaging, examination for ataxia, fine motor and cognitive function, planning abilities, and executive function. Individual consolidated cerebellar lesions were drawn manually onto patients’ individual MRI and normalized into Montreal Neurologic Institute (MNI) space for further analysis with voxel-based lesion symptom mapping. Results Lesion symptom mapping linked deficits of motor function to the superior cerebellar peduncle (SCP), deep cerebellar nuclei (interposed nucleus (IN), fastigial nucleus (FN), ventromedial dentate nucleus (DN)), and inferior vermis (VIIIa, VIIIb, IX, X). Statistical maps of deficits of intelligence and executive function mapped with minor variations to the same cerebellar structures. Conclusion We identified lesions to the SCP next to deep cerebellar nuclei as critical for limiting both motor and cognitive function in pediatric cerebellar tumor survivors. Future strategies safeguarding motor and cognitive function will have to identify patients preoperatively at risk for damage to these critical structures and adapt multimodal therapeutic options accordingly.

Cryosurgical method is used in treatment of patients with glial tumors which localized in depth and functionally meaningful brain areas. These patients are generally considered as inoperable and receive conservative treatment. Their prognosis has become worse as compared to the patients whose brain tumor is available for surgical removal. The authors used a multiway stereotactic destruction of tumors by cryosurgical cannula, which is inserted in bone cutter opening using manipulator. MR-imaging and PET/CT of brain were applied for stereotactic guidance. The majority of patients who underwent this operation didn’t noticed any loss of quality of life. The rates of survival were higher than corresponding indicators for patients who were treated only by chemo- or radiation therapy and the rates were equal to the patients underwent the radical operations. Thus, the multiway stereotactic cryodestruction is a new, safe and effective method of surgical treatment for the patients with tumor localization in such areas, that their location blocked an application of traditional surgical removal by open method.

Abstract BACKGROUND The brain tumor has a highest mortality rate among childhood malignant tumors. Development of peripheral blood stem cell transplant combined chemotherapy and radiation therapy improved the survival rate of patients with pediatric brain tumor drastically late years. Because of its complicated treatment plan, neurosurgeons cannot readily manage these aggressive therapies which require minute whole body control including prevention of lethal infection due to bone marrow suppression. Even if such treatment is effective and patient survives, the aftereffects may reduce patient’s QOL. PURPOSE We report outcomes of the patients with CNS tumor after multimodality treatment. In addition, we introduce the activity contents by the in-hospital children brain tumor multi-disciplinary medical treatment team organized in March 2016. METHODS We retrospectively reviewed 29 patients (under 15 years old) diagnosed as CNS tumors with total of 43 tumor surgeries between January 2001 and December 2019. RESULTS The histopathological diagnoses were 7 germ cell tumor, 7 astrocytic tumor, 4 ependymal tumor, 4 medulloblastoma, 2 craniopharyngioma, 2 AT/RT and 3 others. The mean age at first surgery was 7.4 y.o. (range: 0.3–14.8). Both chemotherapy and radiation therapy were performed in 22 cases out of 29. There were 15 survivors (11 ambulant, 3 W/C, 1 bedridden), 12 deaths, 2 lost follow-ups. Mean follow-up period was 66 months (range: 1–206). CONCLUSION To improve outcomes, we hold on a regular basis of team meeting, discuss treatment plan, and share information. Recently, we also care issues of the patients, such as fertility and palliative medicine.
